Chemical machinery raw material screening device

Abstract

The invention relates to the technical field of chemical machinery raw material screening, and discloses a chemical machinery raw material screening device. The chemical machinery raw material screening device comprises a box body, a motor and a material outlet pipe. A rotating ball and a bevel gear A are arranged at the output end of the motor, a wavy channel is linked with a dust removal device,and the bevel gear A meshes with a rotating device which conducts centrifugal force automatic screening operation on raw materials. According to the chemical machinery raw material screening device,due to the fact that a screening cylinder and a raw material screening net are arranged, chemical machinery raw materials pass through a material outlet plate and intermittently enter a cavity of theraw material screening net, the chemical machinery raw materials with the small size are discharged from a discharging pipe A, the raw materials with the large size enter a discharging pipe B to be discharged, and accurate screening operation of the solid chemical machinery raw materials with the different sizes is achieved; due to the fact that a rotating column and soft bristles are arranged, the purpose that the solid chemical machinery raw materials are subjected to cleaning and dust removal is achieved; and due to the fact that the dust removal device is arranged, the purpose that the dust of the solid chemical machinery raw materials cleaned by the soft bristles is processed under the action of continuous air blowing operation is achieved, and the dust in a cavity of the box body isblown away.

Description

technical field [0001] The invention relates to the technical field of chemical machinery raw material screening, in particular to a chemical machinery raw material screening device. Background technique [0002] Chemical machinery is the general term for machines and equipment used in chemical industrial production. In order to process raw materials into finished products of a certain specification in chemical production, it often needs to go through a series of chemical processes such as raw material pretreatment, chemical reaction, and separation and purification of reaction products. The machinery used to realize these processes is often classified as chemical machinery, and chemical raw materials need to be screened by screening devices in the process of processing. [0003] However, the chemical machinery raw material screening devices in the prior art generally have the following defects. Due to the different volumes of solid chemical machinery raw materials, traditio...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a chemical machinery raw material screening device, which has the advantages of improving the screening efficiency and cleaning the dust of solid chemical machinery principles, and solves the problem that traditional screens are easy to mix small-volume raw materials into large-volume Among the raw materials, the screening is not accurate. Secondly, there is a large amount of dust in the raw material particles of chemical machinery. The existing technology cannot clean and remove dust during the screening process.
