Animal waste fermentation tank

Abstract

The invention discloses an animal waste fermentation tank. The animal waste fermentation tank comprises a main fermentation tank, supports, a feeding channel and a sealing cover plate, wherein the feeding channel is formed in the top of the side surface of the main fermentation tank, the top of the main fermentation tank is connected with an auxiliary fermentation tank through a one-way pressure reducing valve, biogas in the main fermentation tank is exhausted into the auxiliary fermentation tank through the one-way pressure reducing valve when the pressure of the biogas in the main fermentation tank reaches a certain value, and the problems that a well sealing fermentation tank bursts easily when the pressure exceeds the bearable pressure due to limited bearable pressure of the fermentation tank and the risk degree is high are solved. A water inlet and a water outlet are connected with a heating inner chamber in the bottom of the side surface of the main fermentation tank, the water outlet communicates with a heating water tank through a pipe, a circulating pump is mounted in the heating water tank and connected with the water inlet through a pipe, a heating circulating passage is formed, water heated by the heating water tank is fed into the heating inner chamber through the circulating pump to heat the main fermentation tank, and fermentation in the inner chamber of the main fermentation tank is speeded up effectively.

Description

Technical field [0001] The invention relates to the technical field of fermentation devices, in particular to an animal manure fermentation tank. Background technique [0002] At present, there are many kinds of animal manure regenerative feed fermentation machines on the market. The basic principle is to use biological technology combined with fermentation process technology to effectively treat animal manure according to biological characteristics, and comprehensively utilize animal manure and added materials. The microorganisms are fully fermented by stirring to make the materials completely decomposed. At the same time, the pathogenic bacteria, viruses, eggs, parasites and other harmful elements in the animal feces are killed by heating, and the organic matter is converted into feed. During the fermentation process, the temperature has a great influence on the fermentation, but there are few heating devices for the fermentation tank on the market, and during the fermentation ...

AI Technical Summary

Problems solved by technology

During the fermentation process, the temperature has a great influence on the fermentation, but there are few heating devices for the fermenter in the market, and during the fermentation process, the biogas in the fermenter accumulates more and more, and the pressure of the fermenter is limited. , a well-sealed fermenter is easy to burst when the pressure exceeds its withstand pressure, and the risk is high. Usually, the user will discharge the biogas in the fermenter through the exhaust valve, or connect the gas device through the conduit for combustion, but there is very little biogas The collection device, after the fermentation in the fermenter is completed, the next fermentation or shelving is usually carried out, and the irrigation body needs to be cleaned. The traditional fermenter is rarely equipped with a device for cleaning the inside of the tank. Therefore, we propose a kind of animal excrement Fermenter
