A multi-layer screening device of a powder separator

Abstract

The invention discloses a multi-layer screening device of a powder classifier, which comprises a casing, a powder cutting rotary block is installed in a feeding pipe on the top of the casing, and a plurality of powder feeding grooves and powder cutting rotary blocks are arranged around the powder cutting rotary block. Knife, a feeding gauze is installed under the powder cutting rotary block, a rotating drum is installed under the feeding pipe, a plurality of powder throwing tanks are arranged around the bottom of the rotating drum, and the outlet of the powder throwing tank is equipped with a A heavy plate, an elastic sleeve is installed on one side of the weight plate, a number of impact bars are installed inside the elastic sleeve, a blower is installed in the middle of the inner bottom of the shell, and a plurality of coarse powder outlets are arranged around the inner bottom of the shell, A plurality of fine powder tanks are installed on the inner wall of the housing, and fine powder gauzes are respectively installed on the upper sides of the fine powder tanks. The present invention has the characteristics of further screening the fine powder and enhancing the separation effect of fine powder and coarse powder.

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.
