Defoaming and heat insulation biological fermentation tank

Abstract

The invention discloses a defoaming and heat insulation biological fermentation tank, which comprises a tank body, a stirring motor, a stirring shaft and a jacket. The bottom of the tank body is equipped with a tank bottom wall-scraping mechanism. The stirring shaft is equipped with a defoaming mechanism and a vertical wall-scraping mechanism. A thermal insulation coupling is mounted at the upperend of the stirring shaft. The defoaming and heat insulation biological fermentation tank utilizes the thermal insulation coupling to isolate a butt joint shaft and the stirring shaft, and a cylindrical heat insulation cotton layer is employed for heat preservation wrapping of a rectangular end at the upper end of the stirring shaft, thus effectively ensuring the temperature stability at the upperend of the stirring shaft and not transferring the ambient temperature directly to the fermentation liquid in the tank body. An annular floating drum, L-shaped defoaming rods and a vertical short rodcompose the defoaming mechanism, which can rise and fall along with the liquid level to destroy bubbles timely by the transverse rods of L-shaped defoaming rods and the vertical short rod.

Description

technical field [0001] The invention relates to a biological fermenter, in particular to a defoaming and heat-insulating biological fermenter. Background technique [0002] At present, during the use of biological fermentation tanks, the fermentation effect is often affected by temperature control problems. Since the stirring shaft is directly connected from the outside of the tank to the inside, and there is no temperature insulation protection for the stirring shaft on the top of the tank, As a result, the temperature at the upper end of the stirring shaft is directly transmitted to the tank; in addition, bubbles will appear on the top of the tank during the fermentation process, which may cause overflow and affect the normal use of the fermenter. Therefore, it is necessary to design a defoaming and heat-insulating biological fermentation tank, which can realize the heat insulation and defoaming function of the stirring shaft, and ensure the stable and efficient use of the...
