Melting and washing screening method for kitchen waste treatment system

Abstract

The invention discloses a melting and washing screening method for a kitchen waste treatment system, wherein the kitchen waste treatment system comprises a sorting machine, a high-temperature melting and washing screening machine, a grinding machine, a vibrating screen, a horizontal centrifuge, a pulping machine, a vertical centrifuge and a serous fluid pool, and an inlet of the sorting machine is provided with a feeding apparatus; the melting and washing screening method comprises the following steps of: feeding in a transporting way, cleaning in a sorting way, screening in a melting and washing way, refining in a grinding way, firstly centrifuging, pulping in a hydrating way, and discharging oil in a centrifuging way; the kitchen waste belongs to a ripe material, and is easy to melt in a hydrating way; the material is transported by a screw shaft arranged in the middle, and the screw shaft is reasonable to design, and is convenient, quick and direct to transport the material; three sections of structures with different functions are respectively arranged, i.e. the melting of organic matters, the cleaning of waste residue, and the recovering of moisture can be realized on the same assembly line, so that the cleaned waste residue is good in cleanliness, and good in organic matter use ratio; and the wool to be ground is completely soaked in high-temperature water, so that the organic matter is obvious in cleaning effect.

Description

technical field [0001] The invention relates to the technical field of solid waste disposal, in particular to a melting, washing and screening method of a kitchen waste treatment system. Background technique [0002] Food waste mainly refers to food waste produced by households, canteens, catering industries, etc., commonly known as swill, which is an important part of urban garbage; in view of our country's diet, the amount of food waste is huge; because food waste contains many organic matter Once the food waste rots and deteriorates, the harm it will cause is immeasurable. How to effectively reduce and treat food waste, how to extract and utilize organic materials, and how to achieve efficient treatment of food waste are currently the top priorities of urban sanitation departments considering food waste treatment. [0003] The main components of kitchen waste include rice and flour food residues, vegetables, animal and vegetable oils, meat, bones, etc. In terms of chemic...

AI Technical Summary

Problems solved by technology

This design does not perform high-temperature cleaning of solids during the garbage sorting process, and more organic materials adhere to the surface of the discharged waste residue, which is not conducive to the collection of more organic components; The introduction of high-temperature water washing is not conducive to the recovery of organic materials during the second impurity removal, reducing the actual treatment effect
