[0015] Technical effects and advantages of the present invention:

[0016] The aerobic decomposition and oil collection device for kitchen waste can drive the first and second crushing rollers to rotate in opposite directions through the operation of a crushing motor, so as to quickly crush the kitchen waste. Meanwhile, a biological medium and a microbial mixture are added to a processing box to aerobically digest the kitchen waste in the processing box, so that organic matter in the kitchen is converted into carbon dioxide and wastewater. Meanwhile, two cooling plates are attached to the surface of the kitchen waste to cool the kitchen waste. The density of oil is smaller than that of water, so that the grease floating on the surface of the wastewater is solidified and attached to the surface of the cooling plate. After the wastewater is discharged, it is convenient to separately process the grease and to recycle the grease.

[0017] Air is blown into the ventilation box through an air pump, and the air in the ventilation box is heated through an electric heating pipe, and then the hot air is blown into the treatment box through the ventilation pipe. After the waste water in the treatment box is discharged, the solidified grease at the bottom of the cooling plate is heated to melt the grease quickly, thereby facilitating the recovery of the grease;

[0018] The forward and reverse motors can drive the two cooling plates to rotate. When the two cooling plates are in a parallel state, it is convenient for the crushed food waste to fall into the lower half of the treatment box. When the two cooling plates are attached, they can play a sealing role, and when the food waste is processed, odor is prevented from emitting from the treatment box.

[0019] Through the operation of the aerator, the outside air can be transported into the processing box. When the food waste is aerobically digested, the oxygen concentration in the processing box is increased, the reaction speed is improved, and the processing efficiency of the food waste is accelerated. At the same time, when the aerator finishes working, the support spring supports the sealing ring, so that the exhaust sleeve is quickly retracted into the positioning sleeve, preventing wastewater from entering the fixed sleeve through the exhaust sleeve;

[0020] By rotating the motor, it can drive the lifting screw to rotate, thereby driving the cleaning frame to move up and down in the processing box, automatically cleaning the inner wall of the processing box, avoiding the staff from cleaning the processing box, and reducing the labor intensity of the staff. The aerobic decomposition and oil collection device for food waste can not only quickly process the food waste, but also separate the grease in the garbage, which is convenient for recycling and reuse of the grease.

[0040] Working principle:

[0041] The aerobic decomposition and oil collection device for kitchen waste is used. When the kitchen waste is put into the treatment box 1 through the feed hopper 2, the crushing motor 3 is started, the crushing motor 3 drives the crushing roller 1 4 and the driving gear 5 to rotate, the driving gear 5 drives the crushing roller 2 6 to rotate through the driven gear 7, thereby driving the crushing roller 1 4 and the crushing roller 2 6 to rotate in opposite directions, and the kitchen waste is quickly crushed. At the same time, the forward and reverse motors 9 are started to drive the driving shaft 10 and the driving bevel gear 1 11 to rotate, the driving bevel gear 1 11 drives the cooling plate 12 to rotate through the driven bevel gear 2 24, so that the two cooling plates 12 are parallel to each other, and the crushed kitchen waste falls into the bottom of the treatment box 1, and then the biological medium and the microorganism mixture are added to the treatment box 1;

[0042] The forward and reverse motors 9 rotate in the reverse direction, so that the two cooling plates 12 are attached to each other, and then water is added to the processing box 1 through the water inlet pipe, so that the water surface contacts the bottom of the cooling plate 12, and the kitchen waste is cooled by the cooling plate 12. The density of oil is smaller than that of water, so that the grease floating on the surface of the wastewater solidifies and adheres to the surface of the cooling plate 12;

[0043] Then, the rotary motor 19 and the aerator 26 are started, and the rotary motor 19 rotates in a forward and reverse cycle, driving the rotary shaft 20, the active bevel gear 21 and the active bevel gear 3 22 to rotate. The active bevel gear 21 drives the fixed sleeve 23 to rotate through the driven bevel gear 24, thereby driving the stirring blade 25 to rotate. At the same time, the aerator 26 works to blow air into the fixed sleeve 23, and push the exhaust sleeve 28 out of the positioning sleeve 27. The air enters the treatment box 1 through the exhaust holes around the exhaust sleeve 28. When the food waste is aerobically digested, the oxygen concentration in the treatment box 1 is increased, the reaction speed is increased, and the food waste organic matter is converted into carbon dioxide and wastewater. After the food waste is processed, the carbon dioxide and wastewater are discharged from the treatment box 1. Then, the aerator 26 is closed, and the support spring 30 supports the sealing ring 29, so that the exhaust sleeve 28 is quickly retracted into the positioning sleeve 27 to prevent the wastewater from entering the fixed sleeve 23 through the exhaust sleeve 28.

[0044] After the waste water is discharged, air is blown into the ventilation box 14 through the air pump 15, and the air in the ventilation box 14 is heated by the electric heating tube 16, and then the hot air is blown into the processing box 1 through the ventilation pipe 17 to heat the solidified grease at the bottom of the cooling plate 12 to melt the grease quickly, and then the grease is discharged through the drain pipe, so as to facilitate the recovery of the grease. At the same time, the rotating motor 19 drives the rotating shaft 20 and the active bevel gear three 22 to rotate, and the active bevel gear three 22 drives the lifting screw 32 to rotate in a forward and reverse cycle through the driven bevel gear three 33, thereby driving the cleaning frame 35 to move up and down in the processing box 1, automatically cleaning the inner wall of the processing box 1, avoiding the staff from cleaning the processing box 1, and reducing the labor intensity of the staff.
