Dual-spray washing device for test tube

Abstract

The invention relates to a dual-spray washing device for a test tube. The dual-spray washing device comprises a clamping mechanism, a rotating mechanism, a waste liquid tank and a spray washing mechanism, wherein the clamping mechanism is arranged on the rotating mechanism and is used for fixing the test tube in the clamping mechanism; the rotating mechanism is used for controlling the rotation of the clamping mechanism, and the spray washing mechanism is used for spraying washing liquid into the test tube and comprises a washing liquid tank, a purified water tank, a liquid inlet tube, a liquid pump and a liquid outlet tube; one end of the liquid inlet tube is connected with the washing liquid tank or the purified water tank, and the other end of the liquid inlet tube is connected with the liquid pump; one end of the liquid outlet tube is connected with the liquid pump, and the other end of the liquid outlet tube is toward the test tube; the liquid pump sucks liquid from the washing liquid tank or the purified water tank through the liquid inlet tube and sprays out the washing liquid through the liquid outlet tube; the waste liquid tank is arranged below the rotating mechanism. When the rotating mechanism drives the test tube to the position under the rotating mechanism, the washing liquid in the test tube is poured into the waste liquid tank.

Description

technical field [0001] The invention relates to a cleaning device, in particular to a test tube double spray 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 in the test tube by ha...

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
