Biological energy fermentation tank with protective structure

Abstract

The invention relates to the technical field of microbial ensilage fermentation, in particular to a biological energy fermentation tank with a protective structure. The biological energy fermentationtank comprises a tank body, wherein the tank body is cylindrical in appearance and obliquely extends along the front lower portion; at least two transmission rings fixedly sleeve the outer surface ofthe tank body; a base is arranged below the tank body; driving mechanisms are arranged on the lower portions of two sides, which are close to the transmission rings, of the upper end surface of the base; a pressing plate is arranged on the inner side of the tank body in a sliding manner; a rotating shaft movably penetrates through the middle axis of the pressing plate; the rear end of the rotatingshaft is rotationally connected with the inner wall of the tank body; and a plurality of limiting strips extending in the front-back direction extend from the outer surface of the rotating shaft. Thebiological energy fermentation tank can be well applied to fermentation microbial ensilage of straw, oxygen on the inner side during storage of the straw can be discharged as much as possible, wateris controlled, and the amount of air entering the straw during material taking can be reduced.

Description

technical field [0001] The invention relates to the technical field of micro-storage fermentation, in particular to a bioenergy fermenter with a protective structure. Background technique [0002] Straw fermentation micro-storage is the microbial fermentation storage technology of crop straws, which is a straw storage method to improve the nutritional value of crop straws. In the process of straw micro-storage, microorganisms use sugars in straw feed as substrates and convert them into organic acidic process. After the straw is fermented aerobically, the oxygen is exhausted, and aerobic microorganisms cannot survive. At this time, anaerobic microorganisms start to move. Under anaerobic conditions, they cannot completely convert sugar substrates into water and carbon dioxide, but can only decompose them into various organic acids, including caproic acid, propionic acid, lactic acid, and butyric acid. Wait. These organic acids are ionized in the straw feed, forming a large ...

AI Technical Summary

Problems solved by technology

In the prior art, there is no fermentation device for micro-storage storage, which is usually stored in a kiln, which causes inconvenience in the process of water control, sealing, and subsequent removal of the straw. First, the moisture content of the straw needs to be controlled to 60% during the micro-storage process. %—70%; Secondly, before sealing, it is necessary to press out the oxygen as much as possible, which is laborious and inconvenient, and it is also quite inconvenient to cover the sealing film when sealing; finally, when it is taken out and used as feed, the sealing film needs to be opened, and the When the straw is taken out, the surrounding straw will be loosened, which will allow oxygen to enter, destroy the fermentation balance of the internal straw, and affect the shelf life of the straw
