Mechanical and biochemical reaction device applied to coarse pulp of kitchen waste

Abstract

The invention relates to a mechanical and biochemical reaction device applied to coarse pulp of kitchen waste. A material outlet is formed in the bottom of a reaction cabin; more than three nozzles for spraying and stirring the materials at high pressure are respectively arranged on the lower parts of two side plates of the reaction cabin in a running direction of the materials; a two-shaft conveying mechanism is arranged on the lower part of the reaction cabin; an output shaft of a driving motor is connected with an input shaft of a gear reversing mechanism through a coupler; an input shaft and an output shaft of the gear reversing mechanism are connected with a first main shaft and a second main shaft which are provided with helical blades; the first main shaft and the second main shaft respectively penetrate through the reaction cabin and are mounted on a support base through a bearing; the support base is mounted on a frame; a three-level relay material circulation conveying mechanism comprises a first-level lifting mechanism, a second-level lifting mechanism and a third-level lifting mechanism which are arranged in sequence and connected upwards. The mechanical and biochemical reaction device applied to coarse pulp of kitchen waste, disclosed by the invention, has the characteristics of compact structure, easiness in operation and capability of improving the hydrolysis and acidification efficiency of the coarse pulp.

Description

technical field [0001] The invention relates to a mechanical biochemical reaction device for coarse slurry of kitchen waste, and belongs to the technical field of waste treatment. Background technique [0002] Food waste refers to food residues from food processing and consumption by residents. It has the characteristics of high water, oil, organic matter, and salt content. It is easy to rot and deteriorate, spread germs, and emit bad odors. [0003] At present, the main treatment technologies of food waste at home and abroad mainly include landfill, incineration, composting, physical crushing, feed and anaerobic digestion treatment technologies. In addition to the high content of starch, animal fat, dietary fiber and other organic substances in food waste, it is also rich in nitrogen, phosphorus, potassium, calcium and other elements, which has the characteristics of comprehensive nutrition and extremely high utilization value. At present, the most advanced food waste trea...

AI Technical Summary

Problems solved by technology

At present, the above-mentioned coarse pulp generally needs to be further pulverized and hydrolyzed to enter the anaerobic water treatment system, so a separate beating and hydrolyzed acidification device is required, the equipment is redundant, and there are problems of low beating and hydrolyzed acidification efficiency

In addition, since all materials are ground into the anaerobic system after beating, the technical difficulty of biogas residue treatment is increased, which in turn affects the stable operation of the entire anaerobic system
