Closed gravity particle multistage separation dust remover

Abstract

The invention provides a closed gravity particle multistage separation dust remover which comprises a main body and screening units, and a dust removal air inlet and a dust removal air outlet are formed in the main body, so that dust removal and purification of materials can be realized. Meanwhile, the plurality of screening units are arranged in the main body, and the screening units can be usedfor screening and separating materials with different particle sizes, so that the grading of the materials is realized, and meanwhile, the materials can be screened and purified again. The screening unit each is further provided with an independent discharging pipe, and the graded materials can be independently output. The closed gravity particle multistage separation dust remover has the advantages of simple structure and compact and reasonable design, can simultaneously realize dust removal and classification of the materials by adopting one set of equipment, and is very convenient to use. According to the invention, the problems of large occupied operation space, large equipment maintenance operation amount and the like caused by combined operation of a plurality of sets of equipment required for particle material treatment in the prior art are completely solved.

Description

technical field [0001] The invention relates to the technical field of granular material treatment, and more specifically relates to a closed gravity particle multi-stage separation dust collector. Background technique [0002] In the prior art, the treatment of granular materials usually includes dust removal and classification. For dust removal operations, it is achieved through gravity dust collectors, that is, using the different specific gravity of granular materials and dust, in the flowing air flow, lighter The dust will flow with the wind, and the heavier granular materials will fall directly, so as to realize dust removal. For the classification operation, the vibrating screen is generally used in combination with the particle grade classification equipment. The vibrating screen converts mechanical energy into kinetic energy of the particles to make the particles move on the screen for screening. Particle grade classification equipment is the separation of particle...
