Chemical experiment table

Abstract

The invention discloses a chemical experiment table, and belongs to the field of teaching aids. The chemical experiment table comprises a table board, a cleaning device, a storage device, an oscillating device and a lifting device, wherein the cleaning device, the storage device and the oscillating device are all arranged at the top of the table board; four rectangularly distributed telescopic rods are arranged at the bottom of the table board; each telescopic rod is vertically disposed, and the lower end part of the telescopic rod is in transmission connection with a lifting device; a recycling device is arranged between the lifting device and the table board; a water tap is arranged at a position, beside the storage device, at the top of the table board; a storage rack of an H-shaped structure is arranged beside the recycling device; the bottom of the storage rack is fixedly connected with the top of the lifting device; a water passing tank corresponding to the water tap is arrangedon the table board; two ends of the recycling device are respectively communicated with the water passing tank and the cleaning device. The chemical experiment table can prevent chemical experiment waste liquid from injuring hands of a person due to the cleaning device and the oscillating device; furthermore, the height of the table board can be adjusted by driving executed by the lifting device;the chemical experiment table is relatively high in practicability.

Description

technical field [0001] The invention relates to the field of teaching aids, in particular to a chemical experiment bench. Background technique [0002] Chemistry is a kind of natural science, which studies the composition, properties, structure and changes of substances at the molecular and atomic levels; it is the science of creating new substances. The world is composed of matter, and chemistry is one of the main methods and means used by human beings 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. In the field of modern teaching, in order to deepen students' mastery of knowledge points, a large number of chemical experiment courses will be arranged. The bench is an auxiliary device for students to carry out chemical experiments, and it has been widely used in the field of chemistry teaching. [0003] At present, when conducting chemical experiments,...

Problems solved by technology

[0003] At present, when conducting chemical experiments, in order to fully contact each reaction solution, the test tube is usually manually shaken to observe the state of each solution in the test tube after the reaction, and when the student performs a chemical experiment on the chemical experiment bench, usually It is to pour the experimental solution into the sink, and then manually clean the chemical utensils on the tap. The disadvantages of this method are: first, chemical experiments often use more corrosive reagents that are harmful to the human body. When shaking the test tube, the solution in the test tube is dripped into the hands and the chemical utensils are cleaned by hand, which will cause certain harm to the students; second, pouring the experimental solution into the water tank and directly discharging it will pollute the water environment. It is not conducive to environmental protection; and the height of the existing chemical experiment bench cannot be adjusted, and the practicability is low
