Detailed Description
As shown in fig. 1, the disposable bioreactor bag comprises a bag body 10, a first inner rotor 21 and a first sealing structure 20, wherein the first inner rotor 21 and the first sealing structure 20 are arranged at the bottom of the bag body; the top of the bag body is provided with a second sealing structure 30 which is connected with the bag body in a sealing way, a second inner rotor 31 is pivoted on the second sealing structure and is positioned in the bag body, the second sealing structure is provided with a second outer rotor matching groove 32, and the second outer rotor matching groove is positioned outside the bag body; a stirring shaft 40 is arranged in the bag body, and two ends of the stirring shaft are connected with the first inner rotor and the second inner rotor.
In actual operation, the reaction bag is placed in the steel shell, the outer rotor on the first motor shaft at the bottom of the steel shell is fitted into the first outer rotor fitting groove 22, and the outer rotor on the second motor shaft at the top of the steel shell is fitted into the second outer rotor fitting groove 32. The first motor acts to drive the outer rotor to rotate, and the magnets in the outer rotor act on the magnets of the first inner rotor 21 to drive the first inner rotor to rotate. Likewise, the outer rotor on the second motor shaft drives second inner rotor 31 to rotate. The first motor and the second motor act synchronously to drive the first inner rotor and the second inner rotor to rotate synchronously, and the first inner rotor and the second inner rotor drive the same stirring shaft 40 to rotate.
Any inner rotor comprises an inner rotor shell 210 and an inner rotor magnet 211 sealed in the inner rotor shell, and the stirring shaft 40 is fixedly connected with the inner rotor shell. The stirring shaft is a plastic piece, and the inner rotor shell 210 is a plastic piece, and the two are fixedly connected. The inner rotor is provided with a concave structure, the sealing structure is provided with a convex structure, the bearing is installed on the convex structure, and the bearing is matched in the concave structure, so that the inner rotor is pivoted with the corresponding sealing structure.
