Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen blowing concentrators, and more specifically to a nitrogen blowing concentrator capable of automatically washing a tube wall. Background Art

[0002] Nitrogen blowing concentrator is an instrument used in scientific research experiments, environmental monitoring and evaluation experiments, analytical testing experiments, and material composition analysis and research processes. Nitrogen blowing concentrator concentrates or purifies mixed liquid substances with nitrogen in preparation for subsequent in-depth research and analysis. Nitrogen blowing concentrator can heat, concentrate and purify liquid samples to be tested and analyzed. With the continuous development of science and technology, people's requirements for the manufacturing process of this nitrogen blowing concentrator are getting higher and higher.

[0003] The existing nitrogen blowing concentrator has certain drawbacks during installation and use. During use, the traditional nitrogen blowing concentrator uses a single tube for blowing, which causes liquid to splash easily. In addition, its sealing is not good enough, and it is susceptible to corrosion and pollution. The working efficiency is too low and the waterproof performance is poor, which brings certain adverse effects to people's use process.

[0004] After searching, the Chinese patent with publication number CN215525276U discloses a nitrogen blowing concentrator. By setting up nitrogen blowpipes and using multiple nitrogen blowpipes for spraying, the working efficiency can be improved and the liquid can be prevented from splashing. The No. 1 blowpipe and the No. 2 blowpipe are rotated horizontally by rotating the rotating shaft. In this way, the liquid rotates along the cup wall to produce a vortex, which is not easy to splash out. It is very practical and efficient.

[0005] When the above-mentioned nitrogen blowing concentrator is actually used, during the concentration process, the sample may adhere to the tube wall to form residues, which may contaminate the next sample, resulting in deviation or distortion of the experimental results, increasing the risk of cross contamination and affecting the reliability of the experimental results.
