Sampling device for bioreactor used for removing residual water

Abstract

The invention discloses a sampling device for a bioreactor used for removing residual water. The sampling device structurally comprises a sample collection cylinder, a sampling pulling rod, a residualwater removing device, a connection cup and a sampling straw, an air supply mechanism is arranged for cooperating with rotation of a turbine blade disc to generate airflow, and in cooperation with anair compression mechanism, pushing force is applied to the entering airflow; then powerful airflow is sprayed through an air spraying head along an air conveying mechanism, therefore all internal residual water is brushed away, the blow-drying effect is indirectly achieved, dryness of the inside of the sampling device is ensured, and it is avoided that water corrodes the sampling device; according to the sampling device, a silica-gel drier in a drying mechanism is utilized, a heating bar in the drying mechanism is cooperatively used for drying the drier to achieve repeated using, and therefore after water removal, moisture in existing air in the sampling device can be absorbed; dryness of the internal environment of the sampling device is further ensured, the phenomenon that the interiorof the sampling device is damp is avoided, it is further ensured that the sampling device can be normally used repeatedly next time, and the utilization rate of the sampling device is increased.

Description

technical field [0001] The invention relates to a sampler for a bioreactor for removing residual water, which belongs to the technical field of biological experiments. Background technique [0002] Bioreactor is a kind of biochemical reaction that uses microorganisms to another substance to achieve the desired effect. It is widely used in various industries such as alcohol, pharmaceutical production, organic pollutant degradation, etc., and After the bioreactor reacts, it needs to sample the culture fluid in it. When sampling, it needs to be extracted by a sampler, so as to perform data detection on the culture fluid. However, the existing sampler has the following disadvantages: [0003] After sampling and cleaning, the sampler cannot completely clean out the cleaned liquid due to the gap between the connecting cups, resulting in the remaining water droplets in it, and the water droplets stay in it for a long time, which will make the remaining part often in damp In this s...

AI Technical Summary

Problems solved by technology

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a bioreactor sampler for removing residual water, so as to solve the problem that the sampler of the above-mentioned equipment cannot completely clean the liquid after cleaning due to the gap between the connecting cups after sampling and cleaning. If the liquid stays in it for a long time, it will keep the remaining part in a wet state, which will lead to the continuous growth of bacteria. If it is corroded by bacteria for a long time, it will easily make the inner wall of the sampling tube or the relative Soft corrosion occurs at the connection, causing the sampler to be blocked and damaged, which will cause the sampler to be unusable next time, and cause a waste of resources.
