Test tube cleaning device

Abstract

The invention discloses a test tube cleaning device which comprises a rack, a moving mechanism, a pulling mechanism and a cleaning piece, wherein the moving mechanism can move in the length direction of the rack, the pulling mechanism is movably arranged on the moving mechanism, and the cleaning piece is fixed to the pulling mechanism; the rack comprises a driving screw rod and at least one guide rod, the driving screw rod and the guide rod are parallel to each other, and the driving screw rod is made of a metal material; the moving mechanism comprises an upper plate, a lower plate and a nut, the upper plate and the lower plate are parallel to each other, the nut is fixed to the center of the lower plate, and the nut is in threaded connection with the driving screw. According to the device, cleaning is more thorough, and the phenomenon of attachment residue is eliminated; the cleaning area of the inner wall of the test tube can be increased without manually moving the driving piece, and operation is easy and convenient; the potential safety hazard that a human body is corroded due to splashing of chemical reagents is eliminated, and safe operation is ensured; the cleaning efficiency is improved, and the time required by cleaning operation is shortened.

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
