Abstract

The invention relates to the technical field of teaching tools, in particular to a heating and stirring device for a chemical experiment. The heating and stirring device comprises a stirring body anda heating device, wherein a stirring shaft is arranged on the stirring body, stirring blades are arranged on the stirring shaft, the heating device comprises a heating wire, a switch and a power source which are connected in series, the heating wire is located in the stirring body, a plurality of spoilers are arranged on the inner wall of the stirring body, a liquid discharging pipe is arranged onthe bottom of the stirring body, a manually operated valve is arranged on the liquid discharging pipe, and a liquid injection pipe is arranged at the top of the stirring body. The heating and stirring device is simple in structure, the using cost is reduced, and the heating and stirring device is easy to popularize, and has very good practicality. Meanwhile, the heating and stirring device is convenient to operate, and accordingly the teaching efficiency is improved. The temperature needed by a chemical reaction can be ensured through the heating device, therefore the chemical experimental reaction is conducted sufficiently, what's more, along with perturbation of stirring, the chemical experiment reaction is conducted thoroughly, and the teaching quality is improved.

Description

technical field [0001] The invention relates to the technical field of teaching appliances, in particular to a heating and stirring device for chemical experiments. Background technique [0002] At present, in the teaching process of chemistry courses, a lot of chemical experiments need to be done to enhance students' perceptual knowledge, and in the operation engineering of many chemical experiments, it is necessary to continuously stir the chemical liquids in containers of various sizes . Chemical reactions are divided into exothermic reactions and endothermic reactions, and some chemical reactions will change with changes in temperature, resulting in incomplete reactions. Contents of the invention [0003] The object of the present invention is to provide a heating and stirring device for chemical experiment with simple structure and the function of heating and stirring. [0004] In order to achieve the above object, the technical solution adopted in the present inven...
