[0001] This utility model relates to the technical field of kitchen waste treatment, and in particular to the technical field of integrated four-phase separation equipment for kitchen waste treatment. Background Technology
[0002] With the acceleration of urbanization, the amount of food waste generated is increasing day by day. Traditional food waste treatment methods have many problems, such as low processing speed, unreasonable equipment logic, ineffective water and oil removal, and excessive energy consumption. Traditional spiral structures are prone to entanglement and jamming when encountering common plastic bags, woven bags, beer bottles, and other strip or flexible objects in the waste, requiring manual cleaning and causing downtime. In addition, the heating energy consumption is too high and the oil removal equipment is too complicated. Therefore, it is of great significance to develop a high-efficiency, energy-saving and environmentally friendly food waste treatment system. Summary of the Invention
[0003] The purpose of this invention is to solve the problems in the existing technology by proposing an integrated four-phase separation device for kitchen waste treatment, which can solve the above problems.
[0004] To achieve the above objectives, this utility model proposes an integrated four-phase separation device for food waste treatment, including a storage pot with an opening at the top. A fine residue separation box is located below the storage pot, and the storage pot and the fine residue separation box are separated by a separation net. A plate chain conveyor belt is installed in the storage pot, and the plate chain conveyor belt has filter holes. The discharge end of the plate chain conveyor belt is located above one side of the storage pot. An extrusion screw is rotatably installed in the fine residue separation box, and the extrusion end of the extrusion screw has a fine residue discharge port. A liquid outlet is provided on the fine residue separation box, and an oil-water separation mechanism is located below the liquid outlet.
[0005] Preferably, both the storage pot and the fine slag separation box are conical in shape, with the top being larger than the bottom, and both the storage pot and the fine slag separation box have a double-layer leak-proof structure.
[0006] Preferably, a splash guard is installed at the opening, which seals the inlet when closed.
[0007] Preferably, the storage pot has a mounting groove on its side wall for mounting the plate chain lifting conveyor belt.
[0008] Preferably, the oil-water separation mechanism includes an oil-water separation tank, which is equipped with a boat-shaped oil suction device. The boat-shaped oil suction device includes a hull, and the bottom of the hull is provided with several counterweight chambers. An oil discharge pipe is installed through the hull and connected to a vacuum oil suction pipe.
[0009] Preferably, the oil-water separator is equipped with a hot water circulation pipe, which is heated by a heating device located outside the oil-water separator. The heating device is an electromagnetic heater or a burner.

[0011] Preferably, the storage pot is provided with a vent, and the vent is provided with an activated carbon filter.
[0012] The beneficial effects of this utility model are as follows: This utility model uses a separating net to isolate coarse slag in a storage pot, and a plate chain conveyor belt to separate the coarse slag. Fine slag and liquid enter a fine slag separation box, where an extrusion screw separates the fine slag. The liquid is then discharged into an oil-water separation mechanism for further separation. This completes the four-phase separation of coarse slag, fine slag, liquid water, and liquid oil in one device. This application also has the function of storing waste, making it highly practical. This utility model is equipped with a splash guard that automatically rises when the food waste collection vehicle discharges the waste, preventing splashing. After discharge, it automatically lowers to prevent odor emission. It also prevents leakage, gas expansion, and odor emission during storage and production.

[0023] See Figures 1 to 8 An integrated four-phase separation device for treating kitchen waste includes a storage pot 1 with an opening at the top. A fine residue separation box 2 is located below the storage pot 1, and the storage pot 1 and the fine residue separation box 2 are separated by a separation net 3. A plate chain conveyor belt 4 is installed in the storage pot 1, and the plate chain conveyor belt 4 has filter holes. The discharge end of the plate chain conveyor belt 4 is located above one side of the storage pot 1. An extrusion screw 5 is rotatably installed in the fine residue separation box 2, and the extrusion end of the extrusion screw 5 has a fine residue discharge port 51. A liquid outlet 21 is provided on the fine residue separation box 2, and an oil-water separation mechanism 6 is located below the liquid outlet 21.
[0024] Both the storage pot 1 and the fine slag separation box 2 are cone-shaped with a larger top and a smaller bottom, and both the storage pot 1 and the fine slag separation box 2 have a double-layer leak-proof structure.
[0025] A splash guard 7 is installed at the opening, and the splash guard 7 seals the feed inlet when closed.
[0026] The inner wall of the storage pot 1 is provided with an installation groove for mounting the plate chain lifting conveyor belt 4.
[0027] The oil-water separation mechanism 6 includes an oil-water separation tank 61, which is equipped with a boat-shaped oil suction device 8. The boat-shaped oil suction device 8 includes a hull 81, and the bottom of the hull 81 is provided with several counterweight chambers 82. An oil drain pipe 83 is installed through the hull 81, and the oil drain pipe 83 is connected to a vacuum oil suction pipe 84.
[0028] In the boat-shaped oil extractor, there is an oil drain pipe made of PA hose, PVC hose, or other rigid or flexible pipe with a diameter of 5-200mm. This pipe extends to a suitable position below the liquid oil surface in the oil-water separator. This position ensures that when the boat-shaped oil extractor is on the liquid oil surface, the pipe opening is below the liquid oil surface. At this point, with the assistance of a vacuum device, liquid oil can be extracted. When the liquid oil extraction is complete and the boat-shaped oil extractor is on the water surface, the pipe opening is on the liquid water surface. At this point, the pipe opening is not in contact with the water surface and no water can be extracted. The adjustment principle is that water and oil have different specific gravities, and objects of the same mass will sink to different depths in water and oil. The operation method is to add small doses of high-density substances, such as fine sand or iron sand, to the counterweight chamber of the boat-shaped oil extractor for comparison and adjustment to achieve the conditions described above.
[0029] The oil-water separator 61 is equipped with a hot water circulation pipe, which is heated by a heating device 9 located outside the oil-water separator 61. The heating device 9 is an electromagnetic heater or a burner.
[0030] The heating system of this device is divided into liquid fuel burner heating technology or electromagnetic instantaneous heating technology, depending on the daily processing capacity. This avoids the pollution caused by traditional boiler heating and the high energy consumption caused by resistance heating. The burner or electromagnetic heating can use relatively mature products in the industry.
[0031] The fine slag outlet 51 is connected to a screw conveyor 52, and the discharge end of the screw conveyor 52 is located above one side of the storage pot 1.
[0032] The storage pot 1 is provided with a vent, and an activated carbon filter is provided at the vent.
[0033] Plate chain conveyor belts are composed of stainless steel sheets or thin stainless steel strips. The stainless steel sheets have multiple regularly or irregularly arranged 0.5-10mm holes for separating solid and liquid materials, while the stainless steel strips have gaps of less than 3mm in a certain direction for separating solid and liquid materials. Plate chains of various shapes are used to lift kitchen waste and achieve the goal of solid-liquid separation.
[0034] This invention uses a plate chain elevator to separate coarse slag, and a screw with a speed of 20-110 revolutions per minute combined with vacuum extraction or a fluid pump to separate fine slag. This can effectively improve equipment production efficiency, extend machine life, and reduce the input of manpower and material resources.
[0035] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
