Test tube cleaning device

Abstract

The invention discloses a test tube cleaning device, comprising a frame, a moving mechanism, a pulling mechanism and a cleaning sheet, the moving mechanism can move along the length direction of the frame, the pulling mechanism is movably arranged on the moving mechanism, and the cleaning sheet is fixed on the pulling mechanism Mechanism; the frame includes a driving screw and at least one guide rod, the driving screw and the guiding rod are parallel to each other, and the driving screw is made of metal material; the moving mechanism includes an upper plate, a lower plate and a nut, the upper plate and the lower plate are parallel to each other, and the nut is fixed At the center of the lower plate, and the nut is threaded on the drive screw. In the present invention, the cleaning is more thorough, and the phenomenon of residual attachments is eliminated; the cleaning area of ​​the inner wall of the test tube can be increased without manually moving the driving parts, and the operation is simple; the potential safety hazard of the human body being corroded by splashing of chemical reagents is eliminated, and safe operation is ensured; Cleaning efficiency, shortening the time required for cleaning operations.

Description

technical field [0001] The invention relates to the technical field of test tube inner wall cleaning, in particular to a test tube cleaning device. Background technique [0002] The test tube is a commonly used instrument in the chemical laboratory. It is mainly used as a chemical reaction container for a small amount of reagents. It is used at room temperature or when heated (it needs to be preheated before heating, otherwise the test tube is easy to burst). Generally speaking, test tubes can be divided into ordinary test tubes, support test tubes, centrifuge test tubes, etc. The main purposes of test tubes are as follows: holding liquid or solid reagents; heating a small amount of solid or liquid; preparing a small amount of gas reactor; collecting a small amount of gas; dissolving a small amount of gas, liquid or solid solute; The reaction container of the reagent is used at room temperature or under heating. [0003] On the other hand, some common chemical combustion e...

Problems solved by technology

[0004] The object of the present invention is to provide a test tube cleaning device. In the present invention, the driving member drives the driving screw to rotate, and the driving screw drives the polarization ring to continuously rotate, thereby pushing the plug to move back and forth. The cleaning sheet swings back and forth, and at the same time, the driving screw drives the moving mechanism to move along the inner wall of the test tube through the nut, so that the cleaning sheet scrapes off the massive particle adherents along the length of the test tube to solve the problem that the massive particle adherents are not easy to scrape off. Incomplete cleaning and a small amount of residues of adherents; manual cleaning has certain safety hazards; low operating efficiency and prolonging the time required for cleaning
