Technical field

The invention relates to the technical field of chemical engineering, in particular to an efficient screening and discharging device for chemical materials.

Background technique

Chemical industry is the abbreviation of "chemical process", "chemical industry", "chemical engineering" and so on. Any technology that uses chemical methods to change the composition or structure of a substance or synthesize a new substance is a chemical production technology, that is, a chemical process, and the resulting product is called a chemical or chemical product. In the beginning, these products were produced in hand workshops, and later evolved into factories, and gradually formed a specific production industry, the chemical industry. Chemical engineering is a science that studies the common laws of the production process of chemical products. The relationship between mankind and chemical industry is very close. Some chemical products have played an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization.

Screening is the use of a sieve to make the fine material smaller than the sieve hole pass through the screen surface, while the coarse material larger than the sieve hole stays on the screen surface, thus completing the process of separating coarse and fine materials. The separation process can be seen as a two-stage composition of material stratification and fine particle penetration. Material stratification is the condition to complete the separation, and the purpose of separation is the proper sieving of fine particles.
