Description

Technical Field

[0001] This utility model relates to the field of bioreactor feeding technology, specifically to an online sterilizable feeding push valve for bioreactors. Background Art

[0002] A bioreactor is a device system that utilizes the biological functions of enzymes or organisms (such as microorganisms) to carry out biochemical reactions in vitro. It is a kind of biological function simulator, such as fermenters, immobilized enzymes, or immobilized cell reactors. It has important applications in winemaking, pharmaceutical production, concentrated jam production, fruit juice fermentation, and the degradation of organic pollutants.

[0003] The commonly used feed valve in bioreactors is the pin-type feed valve. The disadvantage of this type of feed valve is that sterilization is dangerous, as it requires wiping the interface with alcohol and then igniting it. This operation method is not safe and is inconvenient. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an online sterilizable feed push valve for bioreactors, solving the problems mentioned in the background.

[0005] This utility model provides the following technical solution: an online sterilizable feeding push valve for a bioreactor, comprising: a feed pipe and a connector installed on the bioreactor tank, wherein a sleeve is installed on the surface of the feed pipe, the connector is installed on the surface of the sleeve, and a rotary switch is threadedly connected to the surface of the sleeve, a first groove is formed on the surface of the feed pipe, and a first retaining spring is installed on the inner wall of the first groove, and the first retaining spring is connected to the surface of the rotary switch;

[0006] The inside of the conveying pipe is provided with a hollow flow channel, and the surface of the conveying pipe is provided with a feeding port, which is connected to the hollow flow channel.

[0007] Preferably, the surface of the sleeve is provided with a first limiting part, and the surface of the first limiting part is connected to the inner wall of the connector.

[0008] Preferably, the surface of the sleeve is provided with a second groove, and the inner wall of the inner wall of the second groove is engaged with a second retaining spring, the surface of the second retaining spring being connected to the surface of the connector.

[0009] Preferably, the surface of the feed pipe is provided with a first mounting groove and a second mounting groove, which are respectively located on both sides of the feed port. A first sealing ring is installed on the inner wall of the first mounting groove, and a second sealing ring is installed on the inner wall of the second mounting groove. The surfaces of the first sealing ring and the second sealing ring are movably connected to the inner wall of the sleeve.

[0010] Preferably, one end of the conveying pipe is provided with a second limiting part, and the other end of the conveying pipe is provided with a connecting part.

[0011] Preferably, the surface of the sleeve is provided with a third mounting groove, and a second sealing ring is installed on the inner wall of the second mounting groove.

[0012] Preferably, the surfaces of the connector and the rotary switch are knurled with knurled grooves.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This online sterilizable feed valve for bioreactors, consisting of a feed pipe, connector, sleeve, and rotary switch, allows for online sterilization of both the tank and the feed valve. When the feed pipe retracts counter-clockwise to a position flush with the sleeve, the feed port is completely closed, isolating the feed pipe from the tank. This eliminates the need for open flame sterilization. Rotating the feed valve clockwise allows the feed pipe head to enter the tank, exposing the feed port. Activating the feed pump at this point allows material to enter the tank through the feed pipe, enabling continuous feeding. Attached Figure Description
