Description

Centrifugal fermentation cylinder stirring rake

Technical Field

The utility model relates to the technical field of stirring, in particular to a centrifugal fermentation tank stirring paddle.

Background

The stirring paddle of the existing biological fermentation tank is driven to rotate by the stirring paddle, the shearing force generated by the stirring paddle during the rapid rotation is larger, some organisms are sensitive to the shearing force, the larger shearing force is not beneficial to the growth of the organisms, microbial cells are easy to break, and when some extracellular enzymes and extracellular substances are produced, the broken cells in the fermentation liquor are more, the impurities in the fermentation liquor are more, so that the purification of the extracellular enzymes and substances at the later stage is not beneficial. And the rapid rotation of the stirring paddle of the biological fermentation tank can only lead the fermentation liquor in the fermentation tank to rotate transversely or rotate up and down in a small range, which is not beneficial to the dissolution of the gas in the fermentation liquor.

SUMMERY OF THE UTILITY MODEL

The technical problem to be solved by the utility model is to provide a centrifugal fermentation tank stirring paddle, which solves the problems mentioned in the background technology.

In order to solve the technical problem, the stirring paddle of the centrifugal fermentation tank comprises a guide pipe which is vertically arranged, a lower disc is arranged at the top of the guide pipe, a through hole which is matched with the guide pipe is formed in the middle of the lower disc, a plurality of arc-shaped blades are arranged on the surface of the lower disc at equal intervals along the circumferential direction of the through hole, the top of each arc-shaped blade is fixedly connected with an upper disc, and the surface of each upper disc is connected with a motor through a stirring shaft.

As an improvement of the utility model, the arc-shaped blade is provided with 3-8 blades.

As a modification of the utility model, the arc-shaped blade is provided with four pieces.

As an improvement of the utility model, the arc directions of the arc-shaped blades are consistent.

As a refinement of the utility model, the lower and upper discs are of equal diameter.

As an improvement of the utility model, the height of the arc-shaped blade is 1-400 cm.

As an improvement of the utility model, the diameters of the lower disc and the upper disc are 2-500 cm.

As an improvement of the utility model, the distance between the upper disc and the bottom of the draft tube is 10-1000 cm.

Compared with the prior art, the utility model has the advantages that 1) the fermentation liquid in the fermentation tank generates centrifugal force by utilizing the thrust generated by the arc-shaped blades, the centrifugal force enables the fermentation liquid to transversely flow out from the gaps among the arc-shaped blades, and the fermentation liquid in the guide pipe upwards flows due to pressure to fill the fermentation liquid transversely flowing out from the arc-shaped blades, so that the fermentation liquid in the fermentation tank does a large circulation of up-and-down flow while rotating, and the gas in the fermentation liquid is more favorably dissolved; 2) the centrifugal force is generated by the thrust generated by the arc-shaped blades to rotate the liquid, the shearing force generated by the rotation of the stirring paddle is reduced as much as possible, the growth of organisms in the fermentation tank is facilitated, the biological cells in the fermentation box are broken less, impurities in the fermentation liquor are less, and the purification of extracellular enzymes and extracellular substances in the later stage is facilitated.
