Multi-layer screening device of powder concentrator

Abstract

The invention relates to a multi-layer screening device of a powder concentrator. The multi-layer screening device comprises a shell, a powder cutting rotating block is installed in a feeding pipe at the top of the shell, multiple powder feeding grooves and powder cutters are arranged on the periphery of the powder cutting rotating block, a feeding gauze is installed below the powder cutting rotating block, and a rotating cylinder is installed below the feeding pipe. Multiple powder throwing grooves are formed in the periphery of the bottom of the rotating cylinder, a balance weight plate is arranged at an outlet of each powder throwing groove, an elastic sleeve is installed on one side of the balance weight plate, multiple impact rods are installed in the elastic sleeve, an air blower is installed in the middle of the bottom of the inner side of the shell, and multiple coarse powder outlets are formed in the periphery of the bottom of the inner side of the shell. Multiple fine powder grooves are formed in the inner wall of the shell, and fine powder gauzes are mounted on the upper sides of the fine powder grooves correspondingly. The multi-layer screening device of the powder concentrator has the advantages that fine powder can be further screened, and the fine powder and coarse powder separation effect is enhanced.

Description

technical field [0001] The invention relates to the technical field of powder separators, in particular to a multi-layer screening device for powder separators. Background technique [0002] There are many types of powder separators, and different types are suitable for different materials. Different models are also produced according to customer requirements for material fineness. Commonly used separators include cyclone separators, three-separation separators, centrifugal separators, special separators for coal mills, special separators for calcium powder, etc. Later, many high-efficiency powder separators and high-efficiency three-separation powder separators were developed. They are new-generation varieties that improve on the original basis and increase production. [0003] When the existing powder separator is in use, it only separates the coarse powder from the fine powder, and cannot allow the fine powder to be screened and classified; at the same time, the powder m...

Problems solved by technology

[0003] When the existing powder separator is in use, it only separates the coarse powder from the fine powder, and cannot allow the fine powder to be screened and classified; at the same time, the powder materials are easy to stand together, so that the falling coarse powder is mixed with fine powder, which improves the quality of the powder selection.
