Definitions
- This invention concerns a new electromechanical apparatus, with fully electronical automation, designed in three versions, namely:
- the apparatus was expressly studied in the smallest details in order to give solution to the problems connected with the separation, collection, transport and disposal of organic city waste materials in general, and consequently of hygienic-sanitary nature and related to environment pollution, by operating at the source of waste materials the compulsory sorting between wet organic and solid inorganic waste.
- the advantages deriving from the use ofthe apparatus according to this invention are the following: a) compulsory source sorting of organic and inert waste; b) progressive elimination of road trash cans and bells, and containers for sorted and unsorted waste; c) progressive elimination of most open air waste dumps; d) drastic reduction ofthe number of packing machines e) great recovery of organic fluids through the purifying equipments, being subject to recycling as organic fertilizers, f) big savings due to non-investments for the road waste containers, their maintenance and replacement, being no longer required; g) further savings for reduced transport to and from waste dumps and or incinerators, specially if located outside district; h) cleaner and hygienic conditions in homes and in any environment, i) lower pollution risks in urban and non-urban habitats; j) progressive and constant reduction ofthe present taxation levels per head for the item "city cleaning" and other related costs.
- Fig. 1 schematically represents a side view of the apparatus: the cross section of the external case quite clearly illustrates the different mechanical parts where the four phases of organic waste processing take place, and the distinct separation between the motor-pump-transmission cabinet and the zone where the very process is developped;
- Fig. 2 again in a cross section of the outside case represents in front position the four sections forming the processing zone, clearly putting in evidence the clean border between the first zone and the second one, where respectively the first and the second process phases, as well as the third toghether with the fourth, take place.
- Fig. 3 illustrates the same case section seen from the back, having in evidence the electric motor (M) on top, the motor-driven pump (P) and the drive (T) for the various organs ofthe apparatus,
- Fig. 4 top view, puts in evidence the cover of the loading chamber, the location ofthe photocells controlling the cover opening and the port for access to the electronic control unit.
- the present apparatus for processing organic city waste in general is realizable as a component of a quite usual kitchen, like a dish-washing machine, and can be therefore used as built-in equipment, being extractible like a drawer on suitable tracks provided in the furniture. It is plugged into the current net, receiving the power for the treatment process from a traditional electric connection (1), it is connected to the water supply net through the pipe union (2) ofthe inlet flexible hose and to the sewerage through the pipe union (3) of the outlet flexible hose.
- the apparatus consists of a case (4) with an inside frame entirely made of stainless steel, having the shape of a rectangular parallelepipedon with square base, with round angles outside
- two spherical rubber-coated wheels (5) are provided on the rear side, and two screw adjustable feet (6) on the front side, in order to facilitate the displacement and positioning of the machine Outside the apparatus neither hand grips nor control keyboards are present, as it works under fully electronical control, being equipped with a programmed control unit (7) that is located inside the apparatus in the upper part
- the loading phase begins from the top of the machine through the loading port (8) that opens horizontally within a toothed track guide (9) under the control of a photocell ( 10), the electronic beam of which is interrupted by the waste approaching the port (8)
- the garbage is disposed inside the loading chamber (1 1); at this moment the first treatment phase begins
- the port (8) closes under the control of an adjustable timer that is located in the electronic unit (7), and that simultaneously starts a set of special crushing rollers (12, 12a), such rollers, that are six in total, engage one another by couples in such a way that the two couples of rollers having a smaller diameter (12a) work above the couple with the larger diameter (12), that is arranged in centered position with respect to the remaining two, and are suitable for cutting and crushing organic waste materials of consistent hardness and volume, such as animal bones, food residuals, etc
- the crushed waste materials fall by gravity, becoming heavier because of the water absorbed through a couple of pierced stainless steel pipes (13), into the sloping hopper ( 14) leading to
- the third treatment phase develops inside the above mentioned pressing chamber ( 19) and begins by a) shutting off the water flow and powering the electric resistance (20) that raises the temperature of muds up to 120°C, thus giving way to the sterilization phase of the muddy products, b) during the sterilization phase, the flocculation process begins, thus facilitating the sterilization of the entire muddy mass, this flocculation is obtained by means of two shear blades (21), one with cutting edge and the other one with toothed edge, granting a further reduction of muddy crumbs, c) after reaching the preset temperature, the resistance (20) turns off and the water flows again directly and exclusively into the pressing chamber through a stainless steel pipe, the inlet of water expedites the mud cooling that is also facilitated through the centrifugation phase In case of pressure excess situations that might occur inside the pressing chamber ( 19), both the relief valve (23) and safety valve (23a), that are calibrated at a preset pressure, are operated, they are directly connected to the discharge pipeline (3a) leading to the sewer
- the apparatus is ready for a new treatment cycle, or, if required, for an idle self-cleaning treatment "with water only, or adding a glas ofa common disinfectant"
