Abstract

A centrifugal lifting stirrer of a bioreactor is disclosed. The centrifugal lifting stirrer includes a tank body having an opened top. A gear ring is fixedly mounted to the inner wall of the bottom end of the tank body. A drive gear provided with a motor is movably mounted at the middle of the inner wall of the bottom end of the tank body. The drive gear and the gear ring are arranged concentrically. The inner wall of the bottom end of the tank body is provided with an annular slot. The annular slot and the gear ring are concentric. The diameter of the annular slot is smaller than the diameterof the gear ring. A plurality of sliding blocks are disposed in the annular slot in a matched manner and are evenly distributed according to the circle center of the annular slot. A horizontal drivengear is movably mounted to the top end of each sliding block and is between the gear ring and the drive gear. The driven gears can be meshed with the drive gear and the gear ring. A vertical long boxhaving an opened top is fixedly mounted at the top surface of each driven gear, and an accommodating box having an opened top is fixedly mounted to the inner wall of the bottom end of each long box.Connecting pipes are made of stainless steel. Positions of rotary valves of the connecting pipes can be fixed so that match gears can be meshed with racks, and opening or closing of the rotary valvescan be controlled.

Description

technical field [0001] The invention belongs to the field of biotechnology, in particular to a centrifugal lifting agitator for a bioreactor. Background technique [0002] At present, in the mechanical stirring device of biotechnology, the motor is directly connected to the stirring shaft, and the motor is installed outside the stirring device. However, due to the tightness between the motor, the stirring shaft and the stirring device, it is easy to cause bacterial contamination of the cell culture medium, and the stirring The shear force damage of the shaft to the cells is also relatively large, so it is inconvenient to use during the stirring process. Contents of the invention [0003] The invention provides a bioreactor centrifugal lifting agitator to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] The bioreactor centrifugal lifting agitator includes a box with an open top, a horizontal...
