Abstract

The invention discloses a two-level particle product screening device for chemical production. The two-level particle product screening device comprises a bottom plate. A left vertical plate and a right vertical plate are vertically and fixedly arranged on the bottom plate. A screening tank is arranged above the bottom plate and internally provided with a rotation tank. The rotation tank is of a hemisphere shell-shaped structure and is evenly provided with a plurality of through holes. A guiding rod rightwards penetrating the left side wall of the screening tank is horizontally and fixedly arranged on the inner wall of the right side of the left vertical plate. A fan-shaped gear is fixedly provided with a transmission plate, and the diameter of sieve holes in a sieve plate is smaller thanthat of the through holes. The two-level particle product screening device achieves screening of particle-shaped products through rotation of the rotation tank, two-level screening of the particle-shaped products is conducted through the sieve plate, shaking and scattering of raw materials in the rotation tank are accelerated through rotation of the rotation tank, and the screening efficiency is improved; and a scraper blade moves left and right to conduct transverse scraping on particle raw materials on the sieve plate, the particle products are promoted to penetrate the sieve holes of the sieve plate, and the screening efficiency of the particle products is greatly improved.

Description

technical field [0001] The invention relates to the technical field of chemical production, in particular to a secondary screening device for granular products used in chemical production. Background technique [0002] Chemical industry, that is, the chemical industry, has spread to all aspects of human life. In modern life, chemical products are inseparable almost anytime and anywhere. From material life such as clothing, food, housing and transportation to spiritual life such as culture, art and entertainment, chemical products are required to serve them. Some chemical products play an epoch-making important role in the history of human development. Their production and application even represent a certain historical stage of human civilization. Anyone who uses chemical methods to change the composition or structure of substances, or to synthesize new substances belongs to chemical production technology, that is, chemical technology, and the resulting products are called...
