Test tube double-spray-washing and spin-drying device

Abstract

The invention relates to a test tube double-spray-washing and spin-drying device. The test tube double-spray-washing and spin-drying device comprises a clamping mechanism, a rotating mechanism, a liquid waste tank and a spray-washing mechanism. The clamping mechanism is arranged on the rotating mechanism and used for fixing test tubes in the clamping mechanism. The rotating mechanism is used for controlling the clamping mechanism to rotate. The liquid waste tank is arranged below the rotating mechanism. A sealing cap is arranged above the clamping mechanism and the rotating mechanism in a covering mode, and the bottom of the sealing cap is attached to the upper edge of the liquid waste tank. The sealing cap is provided with a spray-washing opening. The spray-washing mechanism sprays cleaning fluid into the test tubes through the spray-washing opening. The spray-washing mechanism comprises a cleaning fluid tank, a purified water tank, a fluid inlet pipe, a fluid pump and a fluid outlet pipe. One end of the fluid inlet pipe is connected with the cleaning fluid tank or the purified water tank, and the other end of the fluid inlet pipe is connected with the fluid pump. One end of the fluid outlet pipe is connected with the fluid pump, and the other end of the fluid outlet pipe penetrates through the spray-washing opening and faces towards the test tubes. The fluid pump pumps fluid from the cleaning fluid tank or the purified water tank through the fluid inlet pipe and sprays out the fluid through the fluid outlet pipe.

Description

Technical field [0001] The invention relates to a cleaning device, in particular to a test tube double spray washing and spin-drying device. Background technique [0002] In experiments or work processes, test tubes are often used for various chemical experiments. The test tube is an important tool in the entire testing process, and cleaning the used test tube is an important step in the post-processing of the experiment. When a large number of test tubes need to be cleaned, manual cleaning is slow due to the large number, which will increase the working time of post-test processing. If the efficiency of the sample bottle cleaning step can be improved, the working gap between the upper batch and the lower batch can be well connected, and the overall efficiency of the inspection work can be improved. [0003] In the existing manual cleaning process, there are the following problems: ① When cleaning, the staff needs to shake the solution in the test tube by hand. If a large number ...

Problems solved by technology

[0003] And in the process of existing manual cleaning, there are following problems: 1. when cleaning, need the staff member to throw out the solution in the test tube with hand, if when operating a large amount of test tubes, repetitive work takes up a large amount of working hours, causes whole cleaning process inefficiencies

[0004] ②Due to the small volume of the test tube, it is easy to pollute the outer surface of the test tube during the process of throwing out the solution, causing secondary pollution and increasing the cleaning workload

[0005] ③During the transfer process, due to the manual operation, human organs such as fingers will come into contact with the sample solution in the test tube, or volatile organic gases enter the human body through the respiratory organs, and the solvent in the test tube solution may be toxic such as toluene and n-hexane. Harmful organic solvents, causing great harm to human health
