Abstract

The invention relates to a pulverizing device, in particular to a solid chemical raw material pulverizing device for a chemistry class in a senior middle school. By the solid chemical raw material pulverizing device for the chemistry class in the senior middle school, time and labor are saved, the experiment is visual, and solid chemical raw materials are pulverized thoroughly. In order to solve the technical problem, the solid chemical raw material pulverizing device for the chemistry class in the senior middle scheme comprises a bottom plate, a collecting box, a cylinder I, a cylinder II, a spring, a wedge block, a breaking box, a cylinder III, a discharge opening, a cylinder IV, a left breaking plate, a valve, a right breaking plate, a contact roller, a funnel, a grinding roller I, a motor I, a motor II, a grinding roller II and a strut, wherein the collecting box, the strut, the cylinder I and the cylinder II are successively arranged on the bottom plate from left to right; the left end of the strut is connected with the funnel; and the motor I is arranged on the left side of the inside of the funnel. By the solid chemical raw material pulverizing device for the chemistry class in the senior middle scheme, effects of time and labor saving, visual experiments and thoroughly pulverizing are achieved.

Description

technical field [0001] The invention relates to a crushing device, in particular to a crushing device for solid chemical raw materials used in high school chemistry classrooms. Background technique [0002] Chemistry is a kind of natural science. It is a science that studies the composition, properties, structure and changes of substances at the molecular and atomic levels, and creates 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, and its achievements are an important symbol of social civilization. There are two forms of chemical change and physical change in chemistry. [0003] A solid is an aggregated state of matter. Compared with liquids and gases, solids have a relatively fixed volume and shape, and their texture is relatively hard. The ground state of a solid is not only the lowest energy...
