Test tube cleaning device for chemical experiment

Abstract

The invention discloses a test tube cleaning device for chemical experiment, and belongs to the technical field of chemical experimental equipment. The test tube cleaning device comprises a test tube cleaning box body, an ultrasonic generator arranged at the bottom of the test tube cleaning box body, a test tube cleaning body moving guide rail fixed to the outer wall of the test tube box body, a test tube cleaning body upper fixed cover movably installed on the test tube cleaning body moving guide rail, and a test tube support telescopically installed on the test tube cleaning body upper fixed cover. The test tube cleaning device disclosed by the invention embodiment can be used for fixing and cleaning test tubes of different lengths, and the ultrasonic cleaning and liquid jet cleaning are combined; the cleaning effect and cleanliness of chemical test tubes are improved, and human bodies are prevented from being damaged by the chemical test tubes in the cleaning process; moreover, according to the test tube cleaning device disclosed by the invention embodiment, the jet pressure of jet holes in test tube fixing columns can be adjusted according to the diameters of the test tubes cleaned, and waste of cleaning solutions and energy is avoided; and the cleaning cost of the chemical test tubes is reduced.

Description

Technical field [0001] The invention relates to the technical field of chemical experiment equipment, in particular to a test tube cleaning device for chemical experiments. Background technique [0002] Chemistry is a kind of natural science, which studies the composition, properties, structure and change laws of substances at the molecular and atomic levels; the science of creating new substances. The world is composed of matter, and chemistry is one of the main methods and means used by humans to understand and transform the material world. It is a subject with a long history and full of vitality. Its achievements are an important symbol of social civilization. There are two forms of change in chemistry: chemical change and physical change. [0003] The test tube is an indispensable experimental tool in chemical experiments. The test tube can be directly heated and used as a reaction vessel for a small amount of reagents. In order to meet the test requirements, the washing of t...

Problems solved by technology

[0004] In the existing technology, the test tubes need to be cleaned after the chemical experiment for future use and storage. In the existing test tube cleaning, a test tube brush is usually used for individual cleaning. When a large number of chemical test tubes are used, it is necessary to manually clean the chemical test tubes. A job that is extremely harmful to the human body, and the work efficiency is extremely low and the cost is high; moreover, chemical test tubes are fragile items, and the test tubes are often broken due to improper operation, resulting in a waste of resources and a large waste of labor. There is still water in the cleaned test tube and cannot be stored immediately
