Screening device for chemical raw material production

Abstract

The invention relates to the technical field of screening for chemical raw material production, and discloses a screening device for chemical raw material production. The screening device comprises araw material drying mechanism, a raw material crushing mechanism and a screening mechanism, the raw material crushing mechanism is arranged at the bottom of the raw material drying mechanism, the screening mechanism is arranged at the bottom of the raw material crushing mechanism, and the raw material drying mechanism comprises a drying box, a stirring motor, a stirring shaft and a scraping blade.According to the screening device for chemical raw material production, the stirring motor is started to drive the stirring shaft to rotate, so that stirring blades are driven to stir chemical raw materials, meanwhile, a heating pipe in a heating box and a fan are started to conduct hot air drying on the raw materials in a drying box, the scraping blade scrapes the inner wall of the drying box, the chemical raw materials are prevented from adhering to the inner wall, the drying box stirs and dries the chemical raw materials with large moisture, the situation that the chemical raw materials with large moisture are agglomerated, so that screening of the chemical raw materials is affected is avoided, and the screening quality is improved.

Description

technical field [0001] The invention relates to the technical field of screening for chemical raw material production, in particular to a screening device for chemical raw material production. Background technique [0002] Chemical raw materials can be divided into organic chemical raw materials and inorganic chemical raw materials. Organic chemical raw materials can be divided into alkanes and their derivatives, alkenes and their derivatives, alkynes and their derivatives, quinones, aldehydes, alcohols, ketones, phenols Classes, ethers, anhydrides, esters, organic acids, carboxylates, carbohydrates, heterocycles, nitriles, halogenated, amidoamides, and others. Inorganic chemical raw materials The main raw materials of inorganic chemical products are chemical minerals such as sulfur, sodium, phosphorus, potassium, calcium (see inorganic salt industry), coal, oil, natural gas, air, water, etc. In addition, the by-products and wastes of many industrial sectors are also raw ma...

AI Technical Summary

Problems solved by technology

[0003] At present, different chemical production or different factories have different requirements for the accuracy of the required raw materials, so screening devices need to be used. During the screening process of existing screening devices, for larger raw materials or chemical products with more moisture The screening of raw materials is difficult, which seriously affects the production efficiency of chemical raw materials
