Environment-friendly energy-saving straw anaerobic fermentation efficient treatment equipment

Abstract

The invention discloses environment-friendly energy-saving straw anaerobic fermentation efficient treatment equipment. The equipment structurally comprises a stirring device, an efficient energy-saving motor, a pressurizing and bubble removing device, a fermentation tank machine body, and supporting legs; the supporting legs are welded at the bottom of the fermentation tank machine body. Comparedwith the prior art, the equipment has the beneficial effects that the pressurizing and bubble removing device consisting of the energy-saving motor, a disc, a pressurizing and bubble removing group, ahinge fork, a reciprocating type movable group and a gas exhaust cover is additionally arranged in an existing anaerobic fermentation tank, and bubbles are broken by increasing the internal pressureintensity of the fermentation tank to achieve the purpose of removing the bubbles, so that straws can be prevented from overflowing due to relatively numerous bubbles generated by stirring, the wasteof the straws is avoided, the production capacity is improved, bacteria can normally breathe, the lignocellulose of the straws can be decomposed, the decomposition efficiency is improved, and the fermentation time is shortened.

Description

technical field [0001] The invention relates to the technical field of anaerobic fermentation equipment, in particular to an environment-friendly and energy-saving anaerobic fermentation efficient treatment equipment for straw. Background technique [0002] Through fermentation, not only the nutritional value of straw is improved, but also the palatability is significantly improved, which greatly enhances the appetite of livestock. The texture of fermented straw will become softer, which is more conducive to the digestion of livestock. At the same time, the fermented straw feed is not easy to mildew and can be stored for a long time Therefore, straw fermentation has opened up a new way for the effective utilization of crop straw in agricultural areas and the development of animal husbandry in agricultural areas in my country. Straw fermentation can generally be divided into anaerobic fermentation and ventilation fermentation according to the different requirements for oxygen i...

AI Technical Summary

Problems solved by technology

[0004] a) The increase of air bubbles will cause the straw to overflow and lead to waste of straw;

[0005] b) Bubbles increase. With the respiration of microorganisms, the bubbles will be filled with carbon dioxide, and the oxygen in the air cannot be exchanged during anaerobic fermentation, which will affect the respiration of bacteria, which is not conducive to the decomposition of lignocellulose, which will increase the fermentation time. , leading to low fermentation efficiency
