Abstract

The invention provides food waste pretreatment equipment which belongs to waste treatment equipment and is used for solving the problems of too violent crushing and too many adhesive materials contained in separated impurities of the traditional waste pretreatment equipment. The food waste pretreatment equipment is characterized in that a first partition board and a second partition board are arranged in a shell; the shell is partitioned into a left space, a middle space and a right space by the first partition board and the second partition board partition, wherein the bottoms of the left space, the middle space and the right space are communicated; a rack is arranged in the middle space, and a lifting mechanism is obliquely fixed on the rack; a horizontal partition board is fixed below the first partition board, a spiral bag breaking device and a mesh screen are arranged below the horizontal partition board in sequence, the mesh screen is connected with the lifting mechanism and a vibrating screen in sequence, a flusher is arranged above the vibrating screen, a spiral transmitter is arranged below the mesh screen, and a feeding pump is arranged at the bottom of the right inner space of the shell; the left inner space of the shell is provided with a booster pump connected with the flusher; and a bevel board group which is obliquely arranged is fixed between the first partition board and the rack. The food waste pretreatment equipment has a compact structure and universal parts and integrates the functions of bag breaking, oil removing and impurity removing; and food residues subjected to impurity removal do not contain glass fragments and are homogeneous and fluidized, thereby being convenient for post-treatment.

Description

technical field [0001] The invention belongs to garbage treatment equipment, in particular to a kitchen garbage pretreatment equipment. Background technique [0002] Food waste refers to a special type of biomass waste collected from restaurants, hotels, government canteens and school canteens, 90% of which are food residues, including starch and grease, and the other 10% are Impurities, including plastic bags, glass bottles, milk cartons, big bones, meat skin, etc. There are two main methods for the resource treatment of existing food waste, one is to produce feed or fertilizer through rapid biological treatment, and the other is to produce biogas through anaerobic digestion. No matter which treatment method is adopted, if the impurities are not effectively separated, the transportation pipeline will be blocked and the stability of the subsequent treatment process will be destroyed. It is worth noting that although the content of glass in the impurities is small, if it is...
