[0031] It achieves the separation of large materials in catering waste through the combination of a screen and a swinging leg. The device includes a frame. In some examples, the frame is a square steel frame structure. The main shaft and the mesh cage are tilted at an angle of 5-10 degrees. The main shaft is installed in the middle, and both ends are fixed to the frame by bearings. The mesh cage is fixed to the middle and lower part of the frame by bolts. During operation, the mesh cage does not move. The main shaft is driven by a motor, and the forward and reverse rotation of the motor is controlled by timing to achieve the left and right swing of the main shaft. The swinging leg is fixed to the main shaft and moves with the left and right swing of the main shaft. The spray device is fixed on both sides of the main shaft and swings with the main shaft.
[0032] After the restaurant waste is filtered by the receiving hopper, it enters the device. The motor drives the main shaft to rotate, and the swing leg is fixed to the main shaft by bolts. The swing leg swings left and right through the main shaft to realize the functions of material selection, bag breaking, and organic matter crushing. The material larger than the mesh of the screen is screened and transported out, and the material smaller than the mesh of the screen enters the back-end crushing, pulping and oil extraction link. Through the swing leg crushing, extrusion and material selection, the organic matter is crushed into the undersize, and the inorganic matter is sent to the oversize through the material selection, realizing the preliminary separation of organic and inorganic matter, and at the same time, the grease flows into the undersize.
[0033] The utility model adds a fixed steel wire rope to the swing leg of the large material sorting machine, fixes the swing leg in the device when it falls off, and prevents the fallen swing leg from entering the rear end conveying spiral and damaging the spiral equipment.
[0034] At the same time, due to the stickiness of grease, some grease will adhere to plastic bags, plastic bottles, cotton cloth, fruit peels and other debris in the kitchen waste, and the device will screen the large objects, causing grease loss on the large objects, especially in winter when the temperature is low, the amount of grease loss will increase. At the same time, a hot water back-spray device is installed in the device to wash the materials, wash the grease in the catering waste into the screened material, reduce grease loss, and improve the oil extraction rate of catering waste.
[0035] The technical solution adopted by the utility model to solve the technical problem is to add a fixing buckle to the main shaft beam, add a fixing buckle at the bottom of the swing leg, and then add a fixing rope such as a wire rope or a chain between the main shaft beam and the buckle at the bottom of the swing leg, so that when the swing leg falls off, the swing leg is fixed on the main shaft beam to prevent the fallen swing leg from entering the rear end spiral and damaging the spiral equipment; at the same time, fixed brackets are welded on both sides of the main shaft beam to fix the spray pipes and nozzles added on both sides, and hot water is used to spray back after oil is extracted at the rear end. When the main shaft beam swings left and right, the nozzle is driven to move left and right to increase the spray range, and the grease adhered to the surface of large pieces of materials such as plastic bags, plastic bottles, cotton cloth, peels, etc. is washed into the screen, thereby improving the grease recovery rate. Compared with the existing equipment and technology, the oil extraction rate of catering waste is improved, and the damage to the rear end equipment is greatly reduced.
[0036] Before feeding production, start the large material sorting device in advance. After the equipment runs stably, start the back-spray of hot water, start feeding, and crush the organic matter through the swing legs. At the same time, break the plastic bags, and let the organic matter pass through the screen into the screened material, while the inorganic matter is discharged at the tail end, thus realizing the separation of organic and inorganic matter. During the production process, if the swing leg is stuck on a hard object and breaks or the fixing bolt breaks, the fallen swing leg will be fixed to the main shaft through the fixing device to prevent damage to the rear-end equipment. After the production is completed, the fallen swing leg will be replaced without affecting the production. During the sorting and crushing process, hot water is sprayed back on both sides of the main shaft to rinse the material, and the grease on the surface of the material is washed into the screened material to reduce grease loss.
