Kitchen waste treatment system

Abstract

The invention relates to a kitchen waste treatment system, and belongs to the technical field of kitchen waste recycling treatment. The kitchen waste treatment system sequentially involves a sorting assembly, a stewing spiral conveying assembly, a sand-water separation assembly, a spiral extrusion dehydration assembly and a gathering spiral conveying assembly according to the treatment sequence ofkitchen waste. According to the kitchen waste treatment system, fine materials sorted by the sorting assembly are subjected to two-stage solid-liquid separation, so that the organic matter in the kitchen waste can be effectively retained so as to be used for subsequent process treatment, and the moisture content of the residue material can be reduced; meanwhile, the sand-water separation assemblyis additionally arranged, the buffer emergency capacity of the whole treatment system is effectively improved, when the subsequent process goes wrong, the sand-water separation assembly and the spiral extrusion dehydration assembly can be used for storing a leaching liquid, so that the flexibility is high, and high economic benefits are achieved.

Description

technical field [0001] The invention belongs to the technical field of kitchen waste recovery and treatment, and in particular relates to a kitchen waste treatment system. Background technique [0002] The amount of food consumed in China is huge. With the development of social economy and the improvement of people's living standards, the amount of domestic waste has increased sharply, and it is increasing at a rate of 8%-10% every year. On the other hand, the harmless disposal rate of waste in China is less than 6%, and more than half of it is food waste. In view of the complex composition and high water content of food waste, at present, the treatment process of large material sorting + cooking screw conveyor + screw extrusion dehydrator is generally adopted for food waste in China. The produced filtrate is transported to the screw extrusion dehydrator, resulting in a low solid content of the material extruded by the screw extrusion dehydrator, and the effect of extrusion...

Problems solved by technology

In view of the complex composition and high water content of food waste, at present, the treatment process of large material sorting + cooking screw conveyor + screw extrusion dehydrator is generally adopted for food waste in China. The produced filtrate is transported to the screw extrusion dehydrator, resulting in a low solid content of the material extruded by the screw extrusion dehydrator, the effect of extrusion dehydration is not very good, and it cannot meet the standards for landfill or incineration
