Up-and-down reciprocating type test tube washing device applied to college chemical experiment

Abstract

The invention provides an up-and-down reciprocating type test tube washing device applied to a college chemical experiment. The up-and-down reciprocating type test tube washing device comprises two brackets; a water storage tank is arranged between the two brackets; the upper part of each bracket is provided with a first rotating shaft; a test tube pedestal is fixedly connected between the two first rotating shafts; one of the rotating shafts is connected with a first motor; the upper side of the test tube pedestal is provided with a plurality of test tube grooves; the sidewall of each test tube groove is provided with a rubber sleeve; an electric heating layer is arranged between one test tube groove and the corresponding rubber sleeve; the upper side of each bracket is provided with an up-and-down reciprocating device which is fixedly connected with a supporting plate; the supporting plate is provided with a plurality of second rotating shafts; each second rotating shaft is arranged in a way of penetrating through the supporting plate; the sidewall of each second rotating shaft is provided with bristles; and the top end of each second rotating shaft is fixedly connected with a driven gear. The up-and-down reciprocating type test tube washing device provided by the invention has the advantages of reasonable structural design, simplicity and convenience in operation, high washing efficiency and the like, and has certain popularization and application values.

Description

technical field [0001] The invention relates to the technical field of chemical experiment teaching, in particular to an up and down reciprocating motion test tube cleaning device for university chemical experiments. Background technique [0002] At present, chemistry is an experiment-based discipline, and the formation and development of chemistry cannot be separated from experiments. After studying in middle school, students have a basic understanding of the subject of chemistry. But for the chemistry study in the university, some students are still at a loss. When students are studying, they not only need to master the contents of the textbook, but also need to use chemical experiments to form chemical concepts, understand and consolidate chemical knowledge, so chemical experiments are particularly important. [0003] In the process of chemical experiments, test tubes are the most common experimental equipment. Test tubes, commonly used instruments in chemical laborator...

Problems solved by technology

[0004] It is used in a large amount, and the test tubes used in the experiment are cleaned manually. Now, the cleaning is basically done by rinsing, rotating in the test tube or rinsing back and forth. It is not very convenient to clean. Moreover, the phenomenon of test tube rupture is also likely to occur during cleaning, thereby injuring students or teachers; in addition, after the test tube is cleaned, the water stains on the inner wall of the test tube are difficult to remove quickly, and are generally dried, which reduces the cleaning efficiency of the test tube
