Dustless feeding, granulating, sieving and smashing system

Abstract

The invention belongs to the technical field of material sieving and smashing equipment, and particularly discloses a dustless feeding, granulating, sieving and smashing system, which comprises a feeding device, a granulating device, a sieving device and a smashing device, wherein the four devices are connected hermetically through a vacuum conveying device respectively. The entire dustless feeding, granulating, sieving and smashing system is formed by introducing dustless feeding, dustless granulating, dustless sieving and dustless smashing into the system, materials are granulated rapidly, and agglomerates among materials are eliminated, so that a part of granulated qualified particles are directly fed into a first qualified product storage bin in a material sieving process, unqualified materials are correspondingly reduced after sieving, and the workload of a subsequent smashing device is reduced simultaneously; the working time and overall material smashing time of the system are reduced, the smashing working efficiency is increase, and the labor intensity of smashing procedure workers is lowered; and meanwhile, the vacuum conveying device is mainly used for conveying materials in the entire system, so that a good working environment is created.

Description

technical field [0001] The invention belongs to the technical field of material screening and crushing equipment, and in particular relates to a dust-free feeding, sizing, screening and crushing system. Background technique [0002] At present, there is no complete dust-free feeding and granulation screening and crushing system in China. The existing various technological processes lack the function of dust-free granulation. The agglomeration of materials during transportation is only achieved by simple agitation to separate the agglomerates. Since there is no fast granulator, some unseparated agglomerated materials will be screened out as unqualified products during the screening, which increases the load on the screening system. At the same time, the increase of unqualified materials will also increase the workload of the crushing system and the work intensity of the crushing workers, which increases the operating cost. [0003] In addition, the domestic crushing system n...

Problems solved by technology

[0002] At present, there is no complete dust-free feeding and granulation screening and crushing system in China. The existing various technological processes lack the function of dust-free granulation. The agglomeration of materials during transportation is only achieved by simple agitation to separate the agglomerates. Since there is no fast granulator, some unseparated agglomerated materials will be screened out as unqualified products in the screening process, which increases the load on the screening system

At the same time, the increase of unqualified materials will also increase the workload of the crushing system and the work intensity of the crushing workers, increasing the operating cost

[0003] In addition, the domestic crushing system needs a huge collector to replace the early bag dust collection. The collector is composed of a cyclone separator and a suction fan. inner wall of feeder

The cyclone separator is not easy to disassemble quickly as a whole, and it is not conducive to quick cleaning. Therefore, the difficulty and workload of cleaning are increased for the replacement of crushed varieties

Part of the material sticks to the surface of the collector and can only be taken out during cleaning, resulting in the reduction of airtight conveying crushed materials, especially the materials taken out during cleaning in pharmaceuticals cannot be used continuously, which causes waste of materials
