A bioreactor device

Abstract

The utility model provides a kind of biological reaction device, it is related to biological reaction equipment technical field, the biological reaction device includes jar body;Stirring part, the stirring part is arranged in the inside of jar body, the stirring part is used to stir the liquid in jar body;Pumping part, the pumping part is arranged in the inner bottom of jar body, the pumping part is used to support the lower end of stirring part, while the liquid of jar body bottom center area is pumped upward, this kind of reaction device because it uses auxiliary shaft, can reduce the length of stirring shaft, improve the rigidity of stirring shaft, and by the rotary connection of cover and stirring shaft, improve the stability of stirring shaft when rotating, while helical blade in the process of following stirring shaft rotation, the material of bottom can be continuously pumped to the upper end of sleeve, realize the circulation flow of jar body inner bottom material, so as to reduce the emergence of dead angle condition, reduce the generation of sediment, improve the transmission efficiency of temperature, avoid each area temperature difference too large.
