Tank for rapid fermentation of livestock and poultry manure

Abstract

The invention belongs to the technical field of fermentation of livestock and poultry manure, specifically to a tank for rapid fermentation of livestock and poultry manure. The tank comprises a tank body, wherein a bottom flange, a middle flange and a top flange are arranged in the tank body; the interior of the tank body is divided into a fermentation chamber and a driving chamber; a main stirring shaft is arranged in the tank body; a plurality of stirring teeth are arranged on the main stirring shaft along an axial direction in a layered manner; the two layers of stirring teeth close to themiddle flange are ventilation stirring teeth; a top air supply channel and a bottom air supply channel are arranged in main stirring shaft and connected with the ventilation stirring teeth respectively; an air supply distributor is arranged on the middle flange; and the bottom air supply channel, the top air supply channel and the air supply distributor are connected with different fans. Accordingto the ventilation stirring teeth and the air supply distributor, air is supplied through different air ducts and fans, so air supply pressure is guaranteed, sufficient oxygen is provided for aerobicfermentation at the bottom of the tank body, fermentation efficiency and quality are improved, a period is short, demands for equipment are reduced, and the cost for purchasing the equipment is reduced.

Description

technical field [0001] The invention belongs to the technical field of livestock and poultry manure fermentation, in particular to a rapid livestock and poultry manure fermentation tank. Background technique [0002] At present, my country's livestock and poultry breeding industry is developing rapidly, and a large amount of livestock and poultry manure will be produced in the process of livestock and poultry breeding, especially in large-scale or large-scale farms. Therefore, it is necessary to carry out harmless treatment of these livestock and poultry manure Or resource utilization, otherwise it will cause waste of resources and environmental pollution. [0003] For the treatment of livestock and poultry manure, the main method is microbial fermentation. The equipment used is mainly a fermenter. The livestock and poultry manure is aerobically fermented in the fermenter under the action of microorganisms, and the activity of microorganisms in the manure is fully utilized to...

Problems solved by technology

[0004] A stirring device and a ventilation device are installed in the fermentation tank, and the function of the stirring device is used to mix the air and the fermented liquid to promote the dissolution of oxygen in the fermented liquid, so as to ensure the supply of microorganisms for growth, reproduction and fermentation. In the prior art, the fermenter uses ventilation stirring blades The air supply and oxygen supply are carried out, so that the air supply efficiency of the ventilation device in the existing fermentation tank is low, the oxygen supply for the fermentation of feces is insufficient, the fermentation speed is slow, the cycle is long, the number of equipment required is large, and the cost is high
