Stackable drawing type adjustable sieve plate

Abstract

A superimposed and extractable adjustable sieve plate belongs to the field of sieve plate equipment, and is composed of an upper plate, a middle plate and a bottom plate. There are uniformly distributed large sieve holes, middle sieve holes are set on the middle plate, and small sieve holes are set on the bottom plate. It is in a concentric state with the small sieve holes. Its structure is simple and reasonable, and its working principle is clear. It is composed of three layers of sieve plates that can move each other. Each layer is equipped with a sieve hole with different specifications. Arrangement, the sieve plate can be adjusted according to the screening object during the screening operation. When the sieve plate is synthesized and used, the wear of the sieve plate can be further reduced. It has high wear resistance, strength and strong impact resistance, and improves the The working efficiency of the sieve plate greatly prolongs the service life of the sieve plate.

Description

technical field [0001] The invention belongs to the field of sieve plate equipment, in particular to a superimposed and extractable adjustable sieve plate. Background technique [0002] Screening operation is a very widely used operation method. It is widely used in mineral processing plants and industrial sectors such as metallurgy, construction, chemical industry and abrasive materials. At present, most of the sieve plates used at home and abroad have the same structure. The size of the sieve holes in the direction of material movement is the same. In this way, the sieve plate with a shorter service life in front determines the service life of the whole set of sieve plates, resulting in waste of sieve plates. [0003] The invention patent application of Chinese Patent No. CN201110437837.9 discloses a composite sieve plate, which is composed of a non-porous sieve plate, a small-hole sieve plate and a large-pore sieve plate. Small, the middle part is a small-hole sieve pla...

AI Technical Summary

Problems solved by technology

Although this patent avoids the waste of the sieve plate structure, it increases the production cost of the sieve plate. Because the material of the sieve plate has not changed, the wear resistance and corrosion resistance of the sieve plate itself have not changed.

In addition, the combined sieve plate cannot be adjusted according to the particle size, and requires a large space during use, which is inconvenient to use
