Abstract

The invention relates to a microcarrier bioreactor tank inner and outer pipeline channel sealing connection device. The device comprises a hard pipe, a sealing connection seat, a sealing connection sleeve and a compression nut. The hard pipe is fixed on a microcarrier frame in a reaction tank, and one end of the hard pipe penetrates through a top cover of the reaction tank; the top cover is provided with a threaded connector, and the threaded connector is connected with the sealing connecting seat. The sealing connecting sleeve which is inserted on the hard pipe in a sleeving manner is arranged in the sealing connecting seat; the compression nut is pressed on the sealing connecting sleeve; the compression nut is connected with the sealing connecting seat; and sealing rings are arranged in the sealing connecting seat and the sealing connecting sleeve. The internal and external pipelines of a microcarrier bioreactor tank can be conveniently connected in a static sealing mode, and compared with the existing dynamic sealing connection mode, the device is safer and more reliable, and the structure is simpler.

Description

technical field [0001] The invention relates to the technical field of bioreactor design, in particular to a sealing connection device for internal and external pipeline channels of a microcarrier bioreactor tank. Background technique [0002] In the reaction tank 13 of the microcarrier bioreactor, a microcarrier frame 14 needs to be set. Due to the obstruction of the microcarrier frame plate, the bent or circular ventilation pipeline cannot be directly inserted into the cell culture area 16 from the tank top cover 15 . The current solution is to figure 1 As shown: an air channel 18 is set at the center of the stirring shaft 17, and is connected with the joint 19 outside the reaction tank 13, so as to access the conveying gas, but this structure needs to be set between the rotating stirring shaft 17 and the stationary joint 19. A seal 20 is used to maintain the airtightness between the inside and outside of the reaction tank 13 . However, the dynamic seal 20 may wear out a...
