Novel air-supply fermentation equipment

Abstract

The invention discloses novel air-supply fermentation equipment. The novel air-supply fermentation equipment comprises a container, a stirring module, and an air supply module, wherein a fermentationspace is formed in the container and used for fermenting materials, a plurality of first air outlet parts are further arranged at the bottom in the container, and the first air outlet parts are used for supplying air into the airtight container at the bottom of the airtight container in a first direction; the stirring module comprises a main shaft, a plurality of stirring blades and a drive mechanism, the stirring blades are arranged on the main shaft, the drive mechanism is used for driving the main shaft to rotate, a second air outlet part is arranged on at least one stirring blade, and thesecond air outlet part is used for leaving from the bottom of the airtight container to carry out air outlet; and the air supply module is used for independently supplying air to the first air outletparts and the second air outlet part separately. Gas supply is carried out through the cooperation of the first air outlet parts at the bottom and the second air outlet part at the middle part, so that a fermentation optimization effect is realized, and the fermentation efficiency is increased.

Description

Technical field [0001] The invention relates to biological reaction equipment, in particular to a new type of air-feeding fermentation equipment. Background technique [0002] At present, with the promotion of industrialized farms, farms will produce a large amount of organic waste such as manure and food residues. How to recycle organic waste in a harmless manner is an urgent problem. Chinese Patent No. 2009101777454 discloses a fermentation and drying treatment device for organic waste. A rotating shaft is arranged in an airtight container, and a stirring blade is arranged on the rotating shaft. The stirring blade is used to agitate the organic waste and the air supply mechanism is used. The air is output through the air outlet on the stirring blade to realize the fermentation of the organic waste in the airtight container. However, this prior art has disadvantages: the mixing blades move intermittently during operation, usually rotating one circle in one hour, and after the ...

AI Technical Summary

Problems solved by technology

However, there are defects in this prior art: the stirring blades move intermittently during operation, and usually rotate once an hour, and after the air is output from the stirring blades, it can only aerate a local area, and the aerobic fermentation process is also limited. In the ventilated area, this will lead to discontinuous air intake of the equipment, uneven fermentation, and seriously affect the fermentation efficiency; The problems of low efficiency and high cost are particularly prominent

In some cases, the density of organic waste in the fermentation device is not uniform, and the defects of low efficiency and high cost caused by the original air supply method are also obvious; the air outlet is set on the bottom mixing blade to output air, which limits the The distance between the blade and the bottom of the container and the arrangement of the blades are not conducive to improving the mixing effect; the use of the hollow inside of the mixing blade to form an air passage is also unfavorable to the improvement of the blade manufacturing process and structural strength.
