Chemical raw material quantitative crushing device

Abstract

The invention discloses a chemical raw material quantitative crushing device. The device comprises a main box body; a coarse crushing cavity is formed in the main box body; a feeding pipe fixedly connected with the upper end wall of the coarse crushing cavity is arranged in the main box body; a vertically-through feeding cavity is formed in the feeding pipe; a lining plate located on the right side of the feeding pipe is fixedly connected to the upper end wall of the coarse crushing cavity; and a sieve plate frame is fixedly connected between the front end wall and rear end wall of the coarse crushing cavity. According to the chemical raw material crushing device, chemical raw materials are subjected to coarse crushing and fine crushing treatment, and the chemical raw materials subjected to the coarse crushing are cooled and then subjected to the fine crushing, so that the problem that volatilization or deterioration is caused due to the fact that generated heat is too high when the chemical raw materials are crushed at a time is solved; meanwhile, the chemical raw materials with more uniform particle sizes can be obtained through two times of crushing; and in addition, generated harmful dust is taken away while the chemical raw materials are subjected to heat dissipation treatment in the fine crushing through a heat dissipation fan, so that the working environment of the chemical raw material crushing is improved, and the health of workers is facilitated.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a quantitative crushing device for chemical raw materials. Background technique [0002] Chemical raw materials generally need to be crushed before they can be put into chemical production. The existing chemical raw materials are usually crushed once in the crushing device. The crushing device easily generates heat during the crushing process of chemical raw materials. Some chemical raw materials are effective after heating The ingredients will volatilize or even deteriorate, affecting the subsequent use of raw materials, and the particle size of the obtained raw materials cannot be guaranteed. In addition, a large amount of harmful dust will be generated during the crushing process, which is not conducive to the health of workers. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a quantitative crushing devic...
