Description

Technical Field

[0001] The utility model belongs to the technical field of culture tank liquid transfer, and in particular relates to a liquid transfer device between culture tanks. Background Art

[0002] A culture tank is a device used in the biological field to cultivate microorganisms, cells, etc. For example, culture tanks are used to cultivate specific strains in microbial fermentation, and culture tanks are used to cultivate cell fluids in cell culture.

[0003] In the application process of culture tanks, such as biological fermentation, it is often necessary to divert the materials in the main tank into different tanks for subsequent processing. Specifically, in the initial stage of the reaction, the amount of reaction materials is large, and a tank with a larger volume is often used as the starting reaction. In the subsequent reaction process, a tank with a reduced volume is often used. At this time, the material solution in the large culture tank needs to be diverted into different tanks.

[0004] During the diversion discharge process, it is often necessary to filter the material. The current filtering method is to install a filter in the material pipe during discharge. However, in actual use, it is often found that the filter is easily deformed during use. The specific reason is that the material tank has a large volume. When discharging the material, the impact force and liquid pressure of the material liquid are relatively large. During filtering, especially at the beginning of the discharge, the filter will be eroded and deformed by the impact of the material liquid, which leads to the need to frequently replace the filter.

[0005] Therefore, in the actual production process, the frequent deformation of the filter makes repair and maintenance very cumbersome. Utility Model Content

Firstly, after the diversion, the scouring of the material solution on the filter structure is reduced, and secondly, the diversion design is used to increase the filtering use time of the filter structure.

[0037] Specifically, the multi-tube filtering mechanism includes an external filtering main pipe 2 (the bottom of the external filtering main pipe 2 is connected to the liquid transfer pipe mechanism), and a tube rack plate 31 is assembled and connected inside the external filtering main pipe 2 (the tube rack plate 31 is circular in shape and is threadedly connected inside the external filtering main pipe 2 by a threaded connection method).
