Abstract

The invention discloses a miniature rotary seal used for a bioreactor. The miniature rotary seal comprises a seal body and a seal ring; the seal body comprises a hollow seal housing and a seal shaft core; the seal ring is an x-shaped silicone rubber seal ring; both the seal housing and the seal shaft core are provided with a pipeline joint; one end of the seal housing is provided with three stopping cards; an annular slot is arranged in the seal shaft core; notches corresponding to the stopping cards are formed in the annular slot; the seal ring is sleeved at one end of the seal shaft core away from the pipeline joint; and the seal housing is sleeved on the annular slot of the seal shaft core through the stopping cards so as to prevent the seal housing from separating with the shaft core. The seal components of the miniature rotary seal provided by the invention are convenient in assembling and disassembling, and convenience is brought for the replacement and washing operations of the seal ring.

Description

technical field [0001] The invention relates to a micro rotary seal, in particular to a micro rotary seal for a bioreactor. Background technique [0002] Equipment that needs to deliver gas or liquid to rotating parts generally requires a rotary seal. For example, a rotary bioreactor is a device used in the fields of cell-scale culture, tissue engineering, and microgravity effect simulation. Due to the needs of cell metabolism, cell culture generally needs to replace the culture medium on time. For the sealed culture method, it is also necessary to use circulation measures to exchange gas in the culture medium to supply oxygen to the cells. Most of the cell culture fluids that use carbonate as a buffer system also need a certain concentration of carbon dioxide to maintain a stable pH value of the culture medium. . Most of these requirements require the online delivery of the culture solution, and the online supply of the rotary culture must rely on the rotary seal. [00...
