Winnowing and separating device

Abstract

The invention relates to a material separation device, in particular to a winnowing and separating device, which comprises a sealed tank body. A feed hopper is arranged on the top part of the tank body; one end parts of two screen meshes are connected to form a splayed sieve through a fixed strip, and the other ends are free ends; sides of the two screen meshes and an end part of the fixed strip are fixed onto a front side wall and a rear side wall of the tank body; the fixed strip is located under a lower end outlet; air inlets and discharge holes are formed in the front side wall and the rear side wall of the tank body; two excess material discharge holes and a large-particle-diameter powder discharge hole are formed in the bottom part of the tank body; the two excess material dischargeholes are located under the free ends of the two screen meshes; and the large-particle-diameter powder discharge hole is formed under the splayed sieve. The winnowing and separating device provided bythe invention is used for sieving firstly to separate large particle matters and then winnowing, so that the accuracy and the efficiency of winnowing are improved, and the amount of powder entering excess materials is reduced.

Description

technical field [0001] The invention relates to a material sorting device, in particular to a wind separation device. Background technique [0002] During the preparation of ceramic glazes and pigments, the ore powder is ground by a ball mill and then enters the winnowing machine for winnowing. After winnowing, the remaining material enters the winnowing collection bin and is discharged from a discharge port set at the bottom. It enters the ball mill for grinding, but about 70% of the qualified powders in the residual material selected by the wind also enter the ball mill for grinding again, resulting in waste of production resources and reducing efficiency. Contents of the invention [0003] In view of the above technical problems, the present invention provides a powder that can simultaneously screen multiple particle sizes, and the specific technical solution is: [0004] The winnowing and separating device includes a sealed box, the top of the box is provided with a f...
