Chemical raw material crushing and refining device

Abstract

The invention discloses a chemical raw material crushing and refining device, and relates to the technical field of chemical engineering. The device comprises a crushing box, a plurality of pairs of crushing blades are fixed to the side wall of a driven shaft at equal intervals, a lifting mechanism used for driving a bearing net plate to vertically ascend and descend is arranged on the crushing box, a crushing mechanism used for impacting and crushing chemical raw materials is arranged on the lifting mechanism, and a discharging hopper is vertically installed at the bottom of the crushing box.Rotation of the driven shaft and a driving shaft is achieved through an arranged transmission mechanism. The driven shaft drives the crushing blades to rotationally crush the chemical raw materials;through the arrangement of the lifting mechanism, materials can be vertically and repeatedly circulated; under the repeated cutting and crushing action of the crushing blades in the circulating process, the arranged lifting mechanism can drive the bearing net plate to vibrate up and down, the turning action of the raw materials is promoted, the raw material crushing effect is more sufficient, arranged extrusion blocks can repeatedly impact and crush the chemical raw materials, and the refining efficiency of the raw materials is greatly improved.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a crushing and refining device for chemical raw materials. Background technique [0002] Chemical industry is the abbreviation of "chemical technology", "chemical industry", "chemical engineering" and so on. 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, and the resulting products are called chemicals or chemical products. At first, what produce this series products is handicraft workshop, develops into factory later, and has gradually formed specific production industry, namely a chemical industry. Chemical engineering is a science that studies the general laws of the production process of chemical products. The relationship between human beings and chemical industry is very close. Some chemical products play an epo...
