A fan feeding dust separator

Abstract

The invention discloses a feeding dust separator employing a fan. The feeding dust separator comprises a cyclone separator, a cyclone bracket, an outer barrel of a dust collector, a dust collector mesh bucket and a dust-catching fan, wherein an inlet of a fan feeding pipeline is formed in one side of the upper part of the cyclone separator; a dust discharge channel is communicated with and arranged at the upper end of the cyclone separator; another outlet of the dust discharge channel is connected with a dust collecting cloth bag for collecting dust; the outer barrel of the dust collector is communicated and connected with the cyclone separator; a material granule outlet is formed in the lower end of the outer barrel of the dust collector; the dust collector mesh bucket is nested with the outer barrel of the dust collector; the upper end of the outer barrel of the dust collector is communicated and connected with a lower outlet of the cyclone separator; a plurality of small holes of which the diameters are less than those of material granules are formed in the wall of the barrel; a dust outlet of the dust-catching fan is connected with another dust collecting cloth bag; a dust suction inlet is connected with two dust-discharge steel wire hoses; and the other end of each dust-discharge steel wire hose penetrates through the outer barrel of the dust collector internally and is arranged on the outer wall of the dust collector mesh bucket. The feeding dust separator is simple in structure, and is capable of finishing dust separation of plastic granules when conveying the plastic granules, and effectively removing the dust in the plastic granules.

Description

technical field [0001] The invention relates to the field of equipment for removing dust from materials, in particular to a dust separator fed by a fan. Background technique [0002] In the preparation process of plastic particle raw materials such as polyethylene and polypropylene, it is inevitable that various dusts are easily generated and mixed in the materials, which greatly affects the next step of the process, so it is indispensable to need The dust removal process is carried out on plastic raw materials, and the existing dust removal methods for various materials mainly include wind dust removal and vibrating plate dust removal. [0003] Among them, the existing wind-force dedusting equipment such as a "granular material wind-force de-powdering equipment" disclosed in Chinese patent CN2613316Y, the wind-force depowdering equipment includes a dry cleaning room, a funnel-shaped dust collector and a bag filter, and the funnel-shaped dust collector includes a column A c...

AI Technical Summary

Problems solved by technology

[0004] The equipment mentioned in the patent can basically complete the preliminary dedusting of the dust in the material, but it cannot further dedust the material after the preliminary treatment, and the dust has a strong adsorption force in some materials such as plastic particles, which is difficult to remove The process of rotary dust removal in the preliminary funnel-shaped dust collector completes a better dust removal effect
