Test tube automatic fluid filling and double-cleaning device

Abstract

The invention relates to a test tube automatic fluid filling and double-cleaning device. The test tube automatic fluid filling and double-cleaning device comprises a clamping mechanism, a rotating mechanism, a cleaning tank and a feeding 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 cleaning tank is arranged below the rotating mechanism. Cleaning fluid is stored in the cleaning tank. The rotating mechanism drives the clamping mechanism to rotate, and when the test tubes in the clamping mechanism are immersed in the cleaning fluid, the test tubes are cleaned. The feeding mechanism comprises a feeding tank, a fluid feeding pipe and a fluid pump. The feeding tank is divided into a cleaning fluid tank and a purified water tank. The cleaning fluid tank is connected with the fluid feeding pipe through a first electromagnetic valve. The purified water tank is connected with the fluid feeding pipe through a second electromagnetic valve. The fluid pump is used for pumping the cleaning fluid or purified water from the cleaning fluid tank or the purified water tank and outputting the pumped cleaning fluid or purified water into the cleaning tank through the fluid feeding pipe.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a test tube automatic liquid injection double cleaning device. Background technique [0002] In the course of experiments or work, test tubes are often used for various chemical experiments. Among them, the test tube is an important tool in the whole detection process, and cleaning the used test tube is an important step in the post-experiment treatment. When a large number of test tubes need to be cleaned, because of the large number, manual cleaning is slow, which will increase the working time for post-test processing. If the efficiency of the sample bottle cleaning step can be improved, the working gap between the previous batch and the next batch can be well connected, and the overall efficiency of the detection work can be improved. [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 i...

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
