An airflow cascade enhanced vibrating screening system

Abstract

The invention discloses an airflow cascade enhanced vibrating screening system, which comprises a screening assembly, the screening assembly includes a vibrating box and a vibrating screen, the upper end of the vibrating box is sealed by a dust cover, and a feeding chute is provided at the left end; Wind device; the vibrating screen is located in the vibrating box, and the material is screened through the vibrating components. The left end of the vibrating screen is lower than the feeding chute, and the right end is inclined downward and close to the chute on the screen. There is an under-screen chute under the vibrating screen. The air induction device includes an air pipe assembly and a main air pipe. Connect with dust collector and induced draft fan in turn. The airflow cascade enhanced vibrating screening system has a simple structure. Through the airflow drag force generated by the air induction device, the ability of the material to penetrate and stratify and touch the screen through the screen is enhanced to achieve efficient deep screening and make the screening effect better.

Description

technical field [0001] The invention relates to the field of screening, in particular to an airflow cascade enhanced vibration screening system. Background technique [0002] Screening technology is a classification process in which broken materials pass through the sieve holes of the sieve surface and are divided into various products with different particle sizes according to their particle size. It is widely used in coal, metallurgy, chemical industry, building materials and other fields. key link. [0003] In the traditional single vibrating field screening process, the dust concentration in the air is high, and the recovery rate of fine particles is low. When performing deep screening, the screening effect is poor. Water spraying is used for dust removal, although it can promote particle penetration through the screen and improve the fine particle size. Particle recovery rate, but it will increase the consumption of water resources, and the mixing of water and micro pa...

[0003] In the traditional single vibrating field screening process, the dust concentration in the air is high, and the recovery rate of fine particles is low. When performing deep screening, the screening effect is poor. Water spraying is used for dust removal, although it can promote particle penetration through the screen and improve the fine particle size. Particle recovery rate, but it will increase the consumption of water resources, and the mixing of water and micro particles will reduce the quality of the product and cause the pollution of the overall equipment; the use of upward induced air for dust removal can reduce the dust concentration in the air, but due to the force of the air flow on the particles upward, it is not conducive to fine particle stratification and sieving
