Teaching demonstration device for chemical industry

Abstract

The invention relates to a teaching demonstration device for chemical industry, and effectively solves the problems that the teaching efficiency is low and demonstration equipment is limited by experimental conditions during chemical teaching demonstration in the prior art. According to the technical scheme, the device can automatically complete reaction among different groups of contrast experiments, the whole process does not need to be controlled by a teacher, the teaching pressure of the teacher in the teaching process can be greatly relieved, and the whole contrast experiment process is carried out continuously; students can clearly compare and understand experiment phenomena generated in different groups of experiment processes, so that the teaching effect is better.

Description

technical field [0001] The invention belongs to the technical field of chemical engineering teaching, and in particular relates to a teaching demonstration device for chemical engineering. Background technique [0002] Chemical industry is the abbreviation of "chemical technology", "chemical industry", "chemical engineering", etc. Any technology that uses chemical methods to change the composition and structure of substances or to synthesize new substances belongs to chemical production technology, that is, chemical technology. known as a chemical or chemical product; [0003] In the process of using chemical methods to synthesize and generate new substances (that is, in the process of chemical reactions), some chemical reactions are carried out under different external environmental factors, and the reaction process and the rate of generating new substances have obvious differences, such as: Temperature, catalyst, etc. In order to enable students to have a deeper understan...

AI Technical Summary

Problems solved by technology

[0004] However, in actual operation, different groups of experiments need to be manually operated by the teacher, that is, one group of experiments is completed before proceeding to the next group of experiments. There is a time interval between them, which also makes the comparison of the experimental phenomena generated during the reflection process less obvious for students (due to a certain time interval in the middle, when the next experiment is carried out, the memory of the students for the previous experimental phenomenon will be weakened), and it is impossible to deepen the students' understanding of the experimental phenomenon. Understanding and cognition of chemical reactions;

[0005] Moreover, during the teaching demonstration process, the teacher not only operates the experiment, but also teaches the students according to the observed experimental phenomena and combined with the textbook content. During the alternate teaching and experimental operation, the teacher is very easy to use during the experimental operation. Mistakes due to panic, due to the production of chemical substances and heat release during the chemical reaction process, once mistakes are made, it is easy to cause experimental accidents and cause safety hazards;
