Test tube washing device for chemical laboratory

Abstract

The invention relates to the technical field of test tube washing equipment and discloses a test tube washing device for a chemical laboratory. The test tube washing device comprises a washing water tank. The top of the washing water tank is fixedly provided with a drive tank. The top of the drive tank is fixedly provided with a drive motor. The outer side of the washing water tank fixedly communicates with a water conveying capillary tube. An inner cavity of the washing water tank is rotationally connected with a water conveying cylinder. The bottom of the water conveying cylinder fixedly communicates with washing tubes. The bottom ends of the washing tubes penetrate and extend into the bottom of the washing water tank. According to the test tube washing device for the chemical laboratory, by arranging an adjusting gear and rotating an adjusting handle, the height of the washing tubes can be adjusted to be inserted into test tubes, by cooperating with washing holes, clean water can flow into the multiple test tubes at the same time, the problems that according to an existing test tube washing device for the chemical laboratory, after chemical experiments are completed, it needs toadd water to the used test tubes to wash the used test tubes one by one, the washing process is tedious, the labor intensity is large, and the washing efficiency is low are solved, and the washing efficiency is effectively improved.

Description

technical field [0001] The invention relates to the technical field of test tube cleaning equipment, in particular to a test tube cleaning device for chemical laboratories. Background technique [0002] The test tube is a commonly used instrument in the chemical laboratory. It is used as a reaction container for a small amount of reagents. It is used at room temperature or under heating (it should be preheated before heating, otherwise the test tube is easy to burst). The specifications of ordinary test tubes are represented by outer diameter (mm) × length (mm), such as 15 × 150, 18 × 180 and 20 × 200. [0003] Test tubes are often used in chemical laboratory experiments. In order to ensure the long-term and clean use of test tubes, the test tubes need to be cleaned from time to time. The existing test tube cleaning devices for chemical laboratories need to clean the used test tubes one by one after the chemical experiment is completed. Adding water to clean, the cleaning p...
