[0033] The working principle of the present application is as follows: Figures 1-3 The catering wastewater enters the automatic residue removal system of the grease trap through the water inlet pipe 2, and the solid-liquid separation of the catering wastewater is completed through the water inlet grille 4. As the solid waste on the upper part of the grille increases, the liquid level on the upper part of the grille pool rises, and when the height of the photoelectric liquid level sensor 5 is reached, the sensor transmits a signal to the intelligent electric control box 28, and the electric control box controls the electric control valve 3 to close and stops water inlet. The residue inlet electric control valve 7 is opened, and the kitchen waste crusher 8 and the variable pitch screw extruder 11 are started. The solid kitchen waste on the inclined water inlet grille 4 enters the automatic residue removal tank 6 by gravity, and is crushed in the kitchen waste crusher 8. The small particle size kitchen waste can enter the variable pitch screw extruder 11 through the ceramic filter disc 9 and the discharge hopper 10. The variable pitch screw extruder 11 has a certain inclination angle. The crushed waste enters the garbage collection bin 12 from the high end of the variable pitch screw extruder by compression. The water content after compression enters the oil-water separation area from the low end of the variable pitch screw extruder through the automatic residue removal tank drain pipe 14. The kitchen waste collection bin is transported away for further processing by manually opening the discharge valve 16 controlled by the electric control box.
[0034] When the solid kitchen waste on the water inlet grille 4 completes a cycle of automatic garbage disposal, the liquid level on the water inlet grille 4 drops, and the photoelectric liquid level sensor 5 will transmit a signal to the intelligent control box 28. The control box controls the opening of the electric control valve 3 and the water outlet valve 15, and the closing of the residue inlet electric control valve 7, the kitchen waste crusher 8 and the variable pitch screw extruder 11, and the automatic garbage disposal system stops working. The oil-containing wastewater together with the automatic residue removal tank outlet water enters the oil-water separation area. In the oil-water separation area, the oil-containing wastewater passes through the water inlet baffle 17-1, the intermediate baffle 17-2, the water outlet baffle 17-3 and the partition plate 19 in turn to form four gallery baffles. The floating oil in the wastewater can fully float by using the density difference. The floated oil is collected by the automatic floating ball skimmer 23 at the upper part of the oil-water separation area and is introduced into the waste oil collection barrel 23-9 through the oil suction pump 24. The separated oil sewage passes through the water outlet baffle 17-3 and enters the water outlet area, and is discharged from the oil separation tank through the water outlet pipe 27. The waste oil collection barrel 23-9 is provided with a cover 23-10 connected with the oil discharge pipe 26. The waste oil collection barrel 23-9 needs to be replaced regularly and the cover of the new collection barrel is connected with the oil discharge pipe. In order to prevent the oil from coagulating into blocks in a low temperature state, the oil suction pipe 25 and the oil discharge pipe 26 are wrapped with a heating sleeve 23-6. The intelligent control box 28 is provided with a temperature sensor 28-1. When the outdoor temperature is lower than 10℃, the heating assembly in the control box starts to heat the oil in the oil suction pipe 25 and the oil discharge pipe 26 through the heating sleeve 23-6.
[0035] Because the organic matter concentration of the restaurant wastewater is high, the dissolved oxygen content of the wastewater in the oil-water separation area of the oil separation tank is low, and methane and other gases are easily produced in the anoxic environment. Therefore, in order to ensure the normal operation of the oil separation tank, an exhaust hole 22 is arranged at the top of the oil separation tank to timely discharge methane and other gases.
[0036] The above-mentioned embodiments are only preferred technical solutions of the present application, and should not be regarded as limiting the present application. The protection scope of the present application should be based on the technical solutions claimed in the claims, including equivalent replacement schemes of the technical features in the claimed technical solutions. That is, equivalent replacement improvements within this scope are also within the protection scope of the present application.
