Detailed description of the invention
The ink ink jet numbering machine filter present invention proposed below in conjunction with the drawings and specific embodiments is described in further detail.According to the following describes and claims, advantages and features of the invention will be apparent from.It should be noted that, accompanying drawing all adopts the form simplified very much and all uses non-ratio accurately, only in order to convenience, the purpose aiding in illustrating the embodiment of the present invention lucidly.
Refer to Fig. 1, it is the structural representation of ink ink jet numbering machine filter of the present invention, as it is shown in figure 1, described ink ink jet numbering machine filter includes: housing 12 and be arranged at the first filter element the 7, second filter element the 9, the 3rd filter element 11 and pressure buffer chamber 5 in described housing 12；Described second filter element 9 is arranged at the outside of described 3rd filter element 11, and described pressure buffer chamber 5 is collectively formed by described second filter element 9, described 3rd filter element 11 and the housing 12 above both；Ink is carried out single filter by described first filter element 7, ink through single filter is carried out cascade filtration by described second filter element 9, ink after cascade filtration is carried out three-stage filtration by described 3rd filter element 11, and the air in described pressure buffer chamber 5 is for cushioning the pressure oscillation filtered and produce at different levels.
Concrete, the first filter element 7 is installed on the bottom of housing 12, during to guarantee work this part can complete wetting in the ink, it is prevented that dry, alleviate ink suction pressure, improve filter effect；The inside opening of described second filter element 9 is positioned at the bottom in pressure buffer chamber 5, ensure the top having partial air to be sealed in pressure buffer cavity 5 all the time, when there is fluctuation in ink pressure, compressibility due to air, this part fluctuation can be filtered out by pressure buffer cavity 5, it is to avoid has influence on the pressure of three grades of filter element 11 outputs.The ink ink jet numbering machine filter of the present invention, while having and stabilizing ink pressure, leaches the impurity in ink circulation, it is provided that filter efficiency efficiently.
Normal operation in order to ensure ink ink jet numbering machine filter, described housing 12 offers the first entrance 1 connected with described first filter element 7, the first outlet 2 connected with described first filter element 7 and the second entrance 6 of connect with described second filter element 9 and connect with main core passage 10 second export 3 and connect with the 3rd filter element 11 the 3rd export 4；Wherein, described first entrance 1 is connected with described first filter element 7 by ink extracting channel 8.Described main core passage 10 is collectively formed by described second filter element 9 and described 3rd filter element 11.
Further, realize filtration at different levels to maintain in ink entrance ink ink jet numbering machine filter, export described first and be additionally provided with compression pump 14 between 2 and described second entrance 6, to provide the driving force needed for ink sucking ink function ink jet numbering machine filter.
Preferably, described ink ink jet numbering machine filter also includes two damper tubes, one of them damper tube 13b is arranged in described second outlet 3, another damper tube 13a is arranged on described second entrance 6, and the damped coefficient that the damped coefficient of the damper tube 13a being arranged on described second entrance 6 is less than the damper tube 13b being arranged in described second outlet 3, thus according to the amount of filtrations actual coincidence situation equilibrium assignment filtered resources (i.e. ink) at different levels, slowing down loine pressure, filter efficiency be substantially improved.
The operation principle of the ink ink jet numbering machine filter of the present invention is as follows:
As shown in Figure 1, in figure arrows be ink ink jet numbering machine filter work time ink the flow direction, first, ink sucks from the first entrance 1 under the effect of compression pump 14, enters ink extracting channel 8 until flowing into the first outlet 2 after the first filter element 7 carries out single filter；Then, again from the first suction side exporting 22 entrance compression pumps 14, ink enters the second filter element 9 after damper tube 13a current limliting from the second entrance 6 after compression pump 14 pressurizes and carries out cascade filtration, ink through cascade filtration is directly entered pressure buffer chamber 5, reducing pressure oscillation by the air in compression pressure cushion chamber 5, the most of ink then passing through cascade filtration exports 3 outflows from second after damper tube 13b current limliting again；Remainder ink through cascade filtration again flows through the 3rd filter element 1111 and carries out third level filtration, and the cleaning ink obtaining pressure stability after the third level is filtered directly feeds the nozzle of ink ink jet numbering machine from the 3rd outlet 4 outflow.
In the present embodiment, the ink of the second outlet 3 outflow is for viscosity monitoring sampling, in addition, second outlet 3 can be passed through the normally opened end of a viscosity monitoring valve and directly connect air in the gap of sampling, guarantee that extraneous air can connect with pressure buffer cavity when ink ink jet numbering machine filter is out of service, it is ensured that during start, cavity has the fluctuation for compensator or trimmer pressure of enough air every time.As can be seen here, one ink ink jet numbering machine filter can realize three-stage filtration and the demand for ink monitoring, and integrated level is high, it is not necessary to for the separately installed filter unit of filter processes at different levels, reduce the space that whole filtration system middle filtrator takies, improve the utilization rate of work space.
To sum up, in ink ink jet numbering machine filter provided by the present invention, described ink ink jet numbering machine filter includes housing and the first filter element being arranged in described housing, the second filter element, the 3rd filter element and pressure buffer chamber；Described second filter element is arranged at the outside of described 3rd filter element, and described pressure buffer chamber is collectively formed by described second filter element, described 3rd filter element and the housing above both；Ink is carried out single filter by described first filter element, ink through single filter is carried out cascade filtration by described second filter element, ink after cascade filtration is carried out three-stage filtration by described 3rd filter element, air in described pressure buffer chamber, for cushioning the pressure oscillation filtered and produce at different levels, improves the stability of pressure in ink；Additionally, due to multiple integrated layouts of being integrally formed of filter element in whole ink ink jet numbering machine filter, it is not necessary to exterior line connects, and pipe-line layout tidiness and reliability are greatly improved.
Foregoing description is only the description to present pre-ferred embodiments, not any restriction to the scope of the invention, any change that the those of ordinary skill in field of the present invention does according to the disclosure above content, modification, belongs to the protection domain of claims.
