Combined solid-liquid separator used in excrement recycling process in livestock and poultry industry

Abstract

The invention provides a combined solid-liquid separator used in an excrement recycling process in a livestock and poultry industry. The combined solid-liquid separator comprises a base, a high-pressure chamber, a stock chamber, a piston movement chamber, a high frequency generator, a feed hopper, a liquid frequency power station, a liquid frequency pump station, a motor, a hydraulic cylinder, a piston, a piston support, a piston head, a high frequency generator, an auxiliary outflow device, a discharge door, and an access door. The combined solid-liquid separator has the advantages that the average value of the content of water in digestate or original residue of excrement is decreased from 77% to 60%, the content of water in the digestate or original residue can be less than 55% after the digestate or original residue of the excrement is dried and sterilized simply, the basic requirements on making of mattress materials of cow in a pasture are met, 18 m <3> of the materials can be processed by the combined solid-liquid separator, only 3-3.8 kwh of electricity is consumed when each cubic meter of materials are processed, electric energy can be greatly saved, and the cow dung can be better processed.

Description

technical field [0001] The invention is mainly used in the technical field of manure recycling in the livestock and poultry breeding industry, and specifically relates to a compound solid-liquid separation device in the process of recycling the manure and sewage in the livestock and poultry breeding industry. Background technique [0002] At present, in the domestic livestock and poultry breeding industry's manure treatment process, most of the solid-liquid separation equipment used (water content is 95%) adopts separators imported from abroad, and a small part of them uses domestic manufacturers. Imported separator. This type of equipment is mainly used in the dairy farms of dairy companies. It can separate the moisture content of the biogas slurry or raw manure liquid from 93% (average) to 77% (average) , the processing capacity of each separator is 5-6 cubic meters per hour, and the processing cost per cubic meter is 2.5-3 kWh. In the pasture manure, after the solid mat...

Problems solved by technology

This brings a series of cost and timeliness issues such as labor, transportation, site, construction, weather, etc.

Most of the pastures are directly discarded due to the high cost of recycling and the lack of technical equipment to solve the problem of excessive water content, resulting in serious environmental pollution problems

[0003] If pastures use biogas residue or raw dung extracted from biogas slurry or raw manure as bedding material for cattle bedding, two problems must be solved: 1. The moisture content of the bedding material must be lower than 55%; 2. Sterilization

The ranch cannot afford such high operating costs
