Multistage bacterial liquid bacteria screening equipment

Abstract

The invention belongs to the technical field of bacteria separation and particularly relates to multistage bacterial liquid bacteria screening equipment. The multistage bacterial liquid bacteria screening equipment comprises a mounting barrel body, a separation module, an automatic collection module and an anti-pollution module; a temporary storage room is arranged at the upper part of the mounting barrel body and is used for temporary storage of bacteria separated by the separation module; a bacterial liquid release tube is communicated wit the lower end of the temporary storage room and is used for releasing the bacteria in the temporary storage room; the separation module is positioned in the temporary storage room and is used for separating the bacteria of different sizes; the automatic collection module is positioned at the lower end of the bacterial liquid release tube and is used for receiving the bacteria of different sizes released from the bacterial liquid release tube; the anti-pollution module is distributed on the mounting barrel body, the temporary storage room and the separation module and is used for preventing external bacteria or the separated bacteria from polluting bacteria that is being separated. The multistage bacterial liquid bacteria screening equipment provided by the invention can quickly separate in batch and respectively store the various bacteria of different sizes in the bacterial liquid and can improve the bacterial liquid bacteria separation efficiency.

Description

technical field [0001] The invention belongs to the technical field of bacteria separation, in particular to a multi-stage screening device for bacteria liquid bacteria. Background technique [0002] In the field of biomedical technology, bacterial culture plays an important role in the diagnosis, prevention, treatment and scientific research of diseases. In the process of bacterial culture, it is unavoidable to occasionally mix other miscellaneous bacteria into the bacterial liquid, and the purpose of culture is to obtain relatively pure bacteria. The bacteria are picked out, at this time, it is necessary to use the bacterial liquid bacterial screening and isolation technology. [0003] In the prior art, there are also some technical solutions for bacterial screening of bacterial liquids. For example, a Chinese patent with application number CN201620075181 discloses a two-stage separation and screening device for medical microorganisms, including "frame, universal wheels, ...

Problems solved by technology

[0003] In the prior art, there are also some technical solutions for the screening of bacterial liquid bacteria. For example, a Chinese patent with the application number CN201620075181 discloses a two-stage separation and screening device for medical microorganisms, including "frame, universal wheels, microbial cylinder , filter cylinder, secondary centrifugal cylinder, primary centrifugal cylinder, mounting plate, rotating shaft, driven pulley, driving pulley, belt, motor, gasket Ⅰ, gasket Ⅱ, centrifugal cylinder cover, inner gasket, top cover, lifting The hand and the outlet are characterized in that: the filter cylinder is provided with multiple filter holes, and the multiple filter holes are evenly distributed at the bottom of the filter cylinder; the secondary centrifugal cylinder is provided with multiple centrifugal holes I, and multiple centrifugal Holes I are evenly distributed on the second-stage centrifugal cylinder; multiple centrifugal holes II are arranged on the first-stage centrifugal cylinder, and multiple centrifugal holes II are evenly distributed on the first-stage centrifugal cylinder; ", this technical solution can only achieve two-stage Separation, only two specific sizes of bacteria can be separated, and it is impossible to separate more bacteria of different sizes. At the same time, in the process of continuous bacterial separation, the bacteria remaining outside the centrifuge cylinder after the previous separation are easy to mix in the next Among the bacteria isolated at one time, the quality of bacterial isolation is reduced, and better purification cannot be obtained, which cannot meet the needs of experiments, let alone the diagnosis, prevention, treatment and scientific research of diseases
