Description

AN APPARATUS FOR MONITORING LIQUID TRANSPORTATION VESSELS AND LIQUID FLOWING THROUGH THEM
CROSS-REFERENCE TO RELATED APPLICATIONS
[001] This application claims the benefit of US provisional application No.
62/032,842 filed on August 4, 2014, the contents of which are herein incorporated by reference.
TECHNICAL FIELD
[002] The present disclosure generally relates to a liquid transfer system, and more specifically, to an apparatus for monitoring aggregation of impurities above a predetermined threshold in liquid transportation vessels.
BACKGROUND
[003] The systems used these days to transfer liquids (e.g., irrigation systems) are deficient in terms of keeping their performances. The liquid flow in transportation vessels is weakened through time due to changes that causes impurities aggregation to be accumulated in the liquid transportation vessels. The changes may be, for example, in the environmental conditions, in the liquid properties, and so on. The impurities aggregation may include organic substances, inorganic substances and bacterial colonies beyond a predetermined standards level. Proper liquid flow in the liquid transportation vessels can be critical, for example, when it comes to saving lives by firefighting systems.
[004] Accumulation of the impurities aggregation can also result in a lack of consistency in the liquid rate. Such inconsistency cannot always be detected until it is too late and the irrigation target areas are harmed, for example, when it comes to irrigation of fields by irrigation systems. It should be noted that some liquid transportation vessels can be blocked and in other liquid transportation vessels can be an increased acceleration of the liquids flowing through them (e.g., over watering).
[005] These days in order to prevent from liquid transportation vessels to be interrupted by the impurities aggregation, the liquid transportation vessels are washed from time to time, or they are maintained by chemicals to reduce the aggregation of impurities in the liquids. Such vessels can be sampled and the
l samples may be further analyzed in order to try to determine whether the liquids flowing through a system is proper to such system. However, there are no effective ways know in the art enabling to measure in real-time the impurities aggregation in each one of the liquid transportation vessels in the system. Therefore interrupted liquid transportation vessels cannot be detected in time.
[006] It would therefore be advantageous to provide a technical solution for monitoring impurities aggregation. It would be further advantageous to overcome the limitations of the prior art by providing an effective way to prevent interruption in the operation of the liquid transportation vessels.

DETAILED DESCRIPTION
[0012] It is important to note that the embodiments disclosed herein are only examples of the many advantageous uses of the innovative teachings herein. In general, statements made in the specification of the present application do not necessarily limit any of the various claimed inventions. Moreover, some statements may apply to some inventive features but not to others. In general, unless otherwise indicated, singular elements may be in plural and vice versa with no loss of generality. In the drawings, like numerals refer to like parts through several views.
[0013] According to certain exemplary embodiments, a liquid transfer system for monitoring liquid transportation vessels and liquid flowing through them is disclosed. In one embodiment, at least one liquid inlet vessel is designed to connect to at least one portion of at least one liquid transportation vessels and at least one stimulation unit. The liquid inlet vessel is connected to the liquid transportation vessel in an area where there is a likelihood that the liquid flow will change as a result of conditions prevailing in such area. Such conditions may include high temperature, high PH, high concentration of Calcium Carbonate (CaC03), and so on. In addition, the stimulation unit designed with a large surface that empowers these conditions. Such stimulation unit may include at least one capturing unit or it may be designed to connect to at least one capturing unit. Such capturing unit is used to capture impurities aggregation accumulated in the liquid inlet vessel, near the liquid inlet vessel and throughout the stimulation unit.
[0014] According to an embodiment, the flow rate of liquid flowing through the stimulation unit is measured. According to another embodiment, the capacity of liquid flowing through the capturing unit is measured, for example, by sensors included therein, to detect accumulation of impurities aggregation above a predetermined threshold. According to yet another embodiment, the capturing unit is designed to be connected to at least one liquid outlet vessel, through which the liquid is released out of the liquid transfer system.
[0015] Fig. 1 shows an exemplary and non-limiting schematic diagram of a liquid transfer system 100 (referred herein after as system 100) utilized to describe the various embodiments disclosed herein. The system 100 includes at least one liquid transportation vessel (e.g., liquid transportation vessel 1 10), at least liquid inlet vessel 120 designed to connect between the liquid transportation vessel 1 10 and a stimulation unit, at least one stimulation unit 130, at least one capturing unit 140 and at least one liquid outlet vessel 160. The system 100 may further include one or more sensors 150-1 through 150-n communicatively connected to the stimulation unit 130 and/or the capturing unit 140 as further described below. [0016] Fig. 1 shows only one liquid transportation vessel 110, one liquid inlet vessel 120, one stimulation unit 130, one capturing unit 140 and one outlet vessel 160 merely for the sake of simplicity.
[0017] The liquid inlet vessel 120 is designed to connect to the liquid transportation vessel 1 0 which may be part of an irrigation system, but the use of such liquid inlet vessel 120 may be also envisioned in the likes of sewerage, drinking water supply system, liquid food supply system, etc.). According to an embodiment, the liquid inlet vessel 120 has two ends (i.e., multi-pipe design). The first end include a central pipe designed to be connected to at least one portion of the liquid transportation vessel 1 10 and the second end include a plurality of sub-pipe branches from the central pipes. The second end is designed to be connected to the stimulation unit 130 so that the liquid enters the stimulation unit 130 is split between the plurality of sub-pipes to allow a piston flow and to prevent hydraulic short. It should be understood that the multi-pipe design is also used for slowing down the liquid flowing into the stimulation unit 130. The Multi-pipe design of the liquid inlet vessel 120 is described in more detail herein below with reference to Fig. 2.
[0018] The stimulation unit 130 is connected to the liquid transportation vessel 110 in an area where the operation of the liquid transportation vessel 1 10 is most affected by the conditions of such area. As an example, these conditions may be, but are not limited to high temperature, high PH, high concentration of Calcium Carbonate (CaC03), etc. Typically, in such area, the flow rate of liquid flowing through the liquid transportation vessel 1 10 is relatively slow, and therefore, the liquid transportation vessels 110 in such area has the greater tendency to be interrupted, for example, blocked respective of impurities aggregation. The stimulation unit 130 includes at least one end that is greater than the liquid transportation vessels 1 10, thereby empowers the conditions that may lead to accumulation and/or aggregation of impurities in the liquid transportation vessels 1 0. According to an embodiment, the stimulation unit 30 has an inner design of a maze that also used to slow the liquid flow rate in the stimulation unit 130.
[0019] The capturing unit 140 comprises a first end 142 designed to be connected to the stimulation unit 130 and a second end 144 designed to be connected to the liquid outlet vessel 160. Such capturing unit 140 is used to capture the impurities that are accumulated and/or aggregated in the liquid inlet vessel 120, near the liquid inlet vessel 120 and throughout the stimulation unit 130. According to an embodiment, the capturing unit 140 may have filtering properties. The filter resolution of the capturing unit 140 can vary depending on the needs. As an example, one capturing unit 140 can capture impurities aggregation above 50 Micron, while another capturing unit 140 can capture impurities at higher resolutions.
[0020] The impurities aggregation may include organic substances, inorganic substances, and bacterial colonies and any combination thereof beyond a predetermined standards level. The accumulation of such impurities aggregation may occur because of, for example, environmental condition affecting the liquid transportation vessels 1 10, the properties of the liquids flowing through the liquid transportation vessels 110, the design of the stimulation unit 130, and the like. It should be understood that the flow rate and/or pressure of liquids flowing through the stimulation unit 130 and/or the liquid capturing unit 140 can be measured when required, for example, in a predetermined time intervals or upon demand.
[0021] According to an embodiment, the capturing unit 140 is designed in a way that it can be disconnect from the system 100, for example, for cleaning purposes, measurements purposes, and so on. According to another embodiment, the impurities aggregation above the predetermined standards level (e.g., 50 Micron) can be detected by one or more sensors 150-1 through 150-n (hereinafter referred to individually as a sensor 150 and collectively as sensors 150) that may be included within any of the liquid inlet vessel 120, the stimulation unit 130 and the capturing unit 140.
[0022] The sensors 150 are configured to perform, for example, quantitative measurements and/or biological measurements to measure the concentration of organic sand/or inorganic substances in the liquid flowing through the system 100. In addition, each of the sensors 150 is configured to detect the presence bacterial colonies. It should be noted that the capturing unit 140 designed to be connected to the stimulation unit 130 from one end and to the liquid outlet vessel 160 from another end. Therefore, after capturing the impurities aggregation in the system 1 10, the liquid is flowing out of the system 100.
[0023] Upon determination that the impurities aggregation (e.g., organic substances and/or inorganic substances, bacterial colonies) is above the predetermined standards level, correction actions are taken manually or under the control of a controller (not shown) to prevent interruptions in the operation of the entire system 100 or part of it. The correction actions may include, for example, correcting the flow rate of the liquid in the liquid transportation vessels 110.
[0024] Fig. 2 depicts an exemplary and non-limiting three dimensional (3D) schematic block diagram of an apparatus 200 comprises a capturing unit with filtering properties for monitoring impurities aggregation according to an embodiment. The apparatus 200 designed with a surface larger than the liquid transportation vessels (not shown) the apparatus 200 is connected to. Such design empowers the conditions affecting the flow rate of liquid flowing through the apparatus 200. Under such conditions there is a high likelihood that the liquid flow rate will slow down and impurities in the liquid will be accumulated and/or aggregated. As an example, the conditions may be, but are not limited to a high temperature, a high PH, a high concentration of Calcium Carbonate (CaC03), and so on. It should be noted that in addition to the mentioned conditions, the liquid transportation vessels can be interrupted respective of the properties of the liquid flowing through it.
[0025] The apparatus 200 comprises at least one liquid inlet vessel 210, at least one stimulation unit 220, at least one capturing unit 230 and at least one liquid outlet vessel 240. Fig. 2 shows only one liquid inlet vessel 210, one stimulation unit 220, one capturing unit 230 and one liquid outlet vessel 240 merely for the sake of simplicity.
[0026] The liquid inlet vessel 210 designed to be connected to the liquid transportation vessel which may be part of a liquid transfer system. The liquid transfer system may be, but is not limited to an irrigation system, sewerage, drinking water supply system, liquid food supply system, and the like. The liquid flowing through the liquid inlet vessel 210 (i.e., central pipe) is split into a sub- pipes 212-1 through 212-m (hereinafter collectively referred to as sub-pipes 212) located inside the stimulation unit 220 to allow a piston flow of liquid into the stimulation unit 220 and to prevent hydraulic short. It should be noted that such dispersed flow of liquid is also used for slowing down the liquid enters the stimulation unit 220.
[0027] By creating a slow liquid flow different type of impurities (e.g., organic substances, inorganic substances) may be aggregated throughout the apparatus 200 (i.e., in the beginning of the apparatus 200 were the sub-pipes 212 are located, throughout the stimulation unit 220 and in the capturing unit 230).The stimulation unit 220 enables the continuous slow liquid flow through it as a result of its structure (i.e., surface larger than the liquid transportation vessel the apparatus 200 is connected to). Such continuous slow liquid flow leads to aggregation and/or accumulation of impurities in the apparatus 200.
[0028] The capturing unit 230 can be connected to the stimulation unit 220 as an external component or it may be part of the stimulation unit 220. The capturing unit 230 disclosed herein includes variable size of holes that enables the capturing unit 230 to filter the liquid in the stimulation unit 230 based on the apparatus 200 requirements. As a non-limiting example, in a case of an irrigation system, there may be a need to detect aggregation of impurities between 50 to 70 Microns, while in other system such need can changed. It should be noted that detection of impurities aggregation between 50 to 70 Microns allows preforming correction actions in time to prevent interruption in the operation of the irrigation system (i.e., blockages in liquid transportation vessels, over watering in liquid transportation vessels).
[0029] The capturing unit 230 can be removed from the apparatus 200, for example, for cleaning purposes, measurements purposes, analyses purposes, and so on. As an example, measurement can then be performed to determine the likelihood of the liquid transportation vessels to be interrupted (e.g., blocked) and thereby enable taking prevention actions. Such measurements can include, for example, sampling the capacity of capturing unit 230 to detect impurities aggregation above a predetermined threshold. In addition, the liquid flow rate in the apparatus 200 can be measured as well as the pressure of the liquid in the apparatus 200. It should be noted that the filtered liquid flows out from the apparatus 200 through the liquid outlet vessel 240.
[0030] Fig. 3 shows an exemplary and non-limiting three dimensional (3D) schematic block diagram of an apparatus 300 comprises a funnel inside of a stimulation unit operative according to an embodiment. The apparatus 300 includes at least one liquid inlet vessel 310, at least one stimulation unit 320 containing the funnel (i.e., funnel 322) inside of it, at least one capturing unit 330 and at least one liquid outlet vessel 340.
[0031] The liquid inlet vessel 310 designed to be connected to a liquid transportation vessel (not shown) of a liquid transfer system. The liquid flows from the liquid transportation vessel through the liquid inlet vessel 310 to the stimulation unit 320. The stimulation unit 320 designed with a surface larger than the liquid transportation vessel to empower the conditions affecting the flow rate of liquid flowing through the liquid transportation vessel. Under such conditions there is a high likelihood that the liquid flow rate will slow down and impurities in the liquid will be accumulated and/or aggregated. It should be noted that in addition to such conditions, the liquid transportation vessel and/or the stimulation unit 320 can be interrupted respective of the properties of the liquid flowing through them. It also should be noted that different type of impurities (e.g., organic substances, inorganic substances, bacterial colonies) may be aggregated throughout different parts of the apparatus 300 as further described below.
[0032] The liquid flows throughout the upper part of stimulation unit 320 so that at least one portion of the impurities aggregation sinks into the funnel 322 and the other portion flows with the liquid toward the capturing unit 330. The capturing unit 330 can be connected to the stimulation unit 320 as an external component or it may be part of the stimulation unit 320. The capturing unit 330 is used to capture the other portion of the impurities aggregation by, for example, filtering the liquid flowing through it. The capturing unit 330 can be removed from the apparatus 300, for example, for sampling the capacity of the capturing unit 330 to detect impurities aggregation above a predetermined threshold. The capturing unit 330 is connected to the liquid outlet vessel 340 so the liquid flows from the capturing unit 330 through the liquid outlet vessel 340 out from the apparatus 300.
[0033] It should be noted that the impurities aggregation accumulated in the funnel 322 can be taken out from bottom of the funnel 322 by, for example, a tap 350 connected to the apparatus 300. The capacity of the impurities aggregation is analyzed to determine, for example, the type of the impurities aggregation and the volume of such aggregation. Correction actions will be performed respective thereof to prevent interruption in the operation of the liquid transfer system (i.e., blockages in the liquid transportation vessels, over watering in the liquid transportation vessels).
[0034] Fig. 4 depicts an exemplary and non-limiting flowchart 400 utilized to describe a method for monitoring impurities aggregation in liquid transportation vessels according to an embodiment. It should be noted that, although discussion of Fig. 4 will be made with respect to the apparatus 200 described in Fig. 2, the steps of this flowchart may be performed with respect to apparatus 300 described in Fig. 3 or another apparatus without departing from the scope of the disclosed embodiments.
[0035] In S410, a slow liquid flow rate is initiated in the inlet of an apparatus (e.g., apparatus 200) connected to at least one liquid transportation vessel. According to a non-limiting embodiment, the liquid flows from the liquid transportation vessel through a liquid inlet vessel (e.g., liquid inlet vessel 210) to a stimulation unit (e.g., stimulation unit 220). The liquid split into a number of sub-pipes (e.g., sub-pipes 212) inside the stimulation unit to allow a slow liquid flow in the inlet of such stimulation unit. The liquid transportation vessel may be part of any type of a liquid transfer system. The slow liquid flow in the inlet of the stimulation unit increases the likelihood of impurities aggregation to be accumulated in the stimulation unit.
[0036] In S420, the accumulation of the impurities aggregation throughout the stimulation unit is empowered respective of the structure of stimulation unit (e.g., surface larger than the liquid transportation vessel) and respective of the location in which the apparatus is connected to liquid transportation vessel as it disclosed herein above with reference to Figs. 1 -3. In S430, the impurities aggregation is captured by a capturing unit (e.g., capturing unit 230) communicatively connected to the stimulation unit.
[0037] According to an embodiment, the capturing unit is configured with filtering capabilities so when the liquid flows through it, impurities aggregation above a predetermined threshold can be captured. According to another embodiment, the capturing unit may include different types of sensors (e.g., sensors 150) that are used to detect and/or capture the impurities aggregation. Such sensors may include, biological sensors that are used to detect the impurities aggregation (e.g., by changing the color of a reagent), quantitative sensors that are used to detect and/or capture accumulation of the impurities aggregation above a predetermined threshold.
[0038] It should be noted that the impurities aggregations may be accumulated in the beginning of the apparatus (e.g., where the sub-pipes 212 are located), throughout the stimulation unit or in the capturing unit. It also should be noted that further analysis can be made to determine the type of the impurities aggregation (e.g., organic substances, inorganic substances, bacterial colonies) and its volume. In S440, it is checked whether the size of the impurities aggregation reached a predetermined threshold and, if so, execution continues with S450; otherwise, execution continues with S460. It should be understood that such threshold may change from one apparatus to another upon demand.
[0039] In 450, correction actions are performed with respect of the operation of the liquid transfer system and/or with the maintenance of such system. According to an embodiment, the correction actions are performed to prevent interruptions in the operation of such system. According to another embodiment, the correction actions are performed to upgrade/improve the maintenance of such system. The corrections actions may be performed manually or under the control of a controller (not shown). In S460, it is checked whether the liquid transfer system needed to be reevaluated (e.g., based on changes in the liquid flow and/or elapsed of predefined interval), If so, execution returns to S210; otherwise, execution terminates.
