Kitchen waste collecting and separating device

Abstract

The invention discloses a kitchen waste collecting and separating device. The kitchen waste collecting and separating device is arranged at the front channel of a kitchen waste treatment production line; the top layer of the collecting hopper of a dual-layer structure consists of a plurality of filter plates with densely distributed with liquid filter holes; a slag discharge hole is formed on the bottom of a hopper; a screening device is arranged below the slag discharge hole; the plate surface of a base plate of a hopper at the lower layer is not provided with holes; and a liquid outlet is formed on the bottom of the hopper, and is communicated with a slag liquid mixing groove through a liquid delivery pipe. According to the invention, aiming at the characteristic of great water content of kitchen waste, solids and liquids in the collecting hopper are separated, the separated liquids enter a screening device and a crashing device, so that adverse influences of high screening and crushing load, poor efficiency and the like caused by too much moisture are prevented, and efficient screening and crushing effects are obtained. According to the invention, not only can the fertilizer efficiency in sewage be fully utilized, but also pollution generated by sewage exhaust as well as the increased sewage treatment appliances and running cost are prevented.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a collection and separation device for kitchen waste. Background technique [0002] The dual attributes of hazard and resource coexist in kitchen waste. On the one hand, kitchen waste has a high oil-water content, generally 80% to 90%. It is perishable and produces stench. Improper disposal (landfill or incineration) will cause serious environmental pollution; and the sources are complex, including viruses, pathogenic bacteria, Pathogenic microorganisms can also cause the spread and infection of pathogenic bacteria, which are more harmful. At the same time, kitchen waste has a high content of organic matter, rich in various trace elements such as nitrogen, phosphorus, potassium, calcium, and animal and vegetable oils, and has high potential resource utilization value. In the existing technology, the harmless and resourceful solutions of food waste include the p...

Problems solved by technology

However, there is no collection and separation device specifically for the characteristics of kitchen waste in the prior art. The sorting site is often flooded with a large amount of sewage and soup, not only the working environment is poor, the ground is slippery and slippery, the smell is unpleasant, and flies are flying around. ; and the direct discharge of these sewage will cause secondary pollution, and a large amount of fertilizer and oil contained in it will be wasted in vain
