A solid chemical raw material crushing device

Abstract

The invention discloses a solid chemical raw material crushing device and mainly relates to the field of raw material crushing devices. The device comprises a base, a supporting frame, a grinding and crushing device, a power transfer connector and a driving motor. The grinding and crushing device comprises a grinding barrel and a rotary grinding roller. A rough grinding cavity, a transition grinding cavity and a fine grinding cavity are formed in the grinding barrel. A rough grinding table, a transition grinding table and a fine grinding table are arranged on the periphery of the rotary grinding roller. A first connection shaft at the bottom of the rotary grinding roller is connected with a connection table. The top of the connection table is provided with a first thrust bearing. The periphery of the connection table is provided with a filter groove. The bottom of a filter net is provided with a containing groove. A second connection shaft at the bottom of the connection table is connected with the output end of the driving motor. The base is further provided with a bearing frame body. The top end of the bearing frame body is provided with a second thrust bearing. The solid chemical raw material crushing device has the beneficial effects that use is convenient, time and labor are saved, the crushing efficiency is high, ground and crushed solid raw materials are uniform in size, and crushing is thorough.

Description

technical field [0001] The invention relates to the field of raw material crushing devices, in particular to a solid chemical raw material crushing device. Background technique [0002] Chemical experiments are the basis for the formation and development of chemical science and the standard for testing the truth of chemical science knowledge. At the same time, chemical experiments can cultivate students' hands-on ability, consolidate the knowledge they have learned, and improve their thinking ability. [0003] The solid raw material in the chemical laboratory, when the experiment is carried out in the reaction vessel, the volume of the reactant is relatively large, and the solid raw material needs to be crushed into powder or smaller particles before the reaction. The existing method is to use similar The cylindrical wooden stick of the rolling pin crushes the solid raw material interlayer paper. Since there are multiple groups in the laboratory, the experiment has been re...

AI Technical Summary

Problems solved by technology

Since there are multiple groups in the laboratory, the experiment has been repeated many times, and more solid raw materials are required. When simply using cylindrical sticks to crush the solid raw materials, it is time-consuming and laborious to use, and it needs to be crushed many times. The solid raw materials are of different sizes, the crushing is not thorough, and the solid raw materials are easy to spill during the crushing process, resulting in waste
