Description

Deduster

Technical field

The utility model relates to a kind of cleaner, especially can be used for the suction type deduster of large tracts of land industrial dedusting.

Background technology

At present, industrial dedusting adopts water flushing dedusting and vavuum pump dedusting dual mode usually, because the water consumption of water flushing dedusting is quite big, current water resource is very in short supply again, therefore this dedusting method is a kind of great waste to water resource, and the vavuum pump dedusting is to utilize the vacuum of motor rotating at high speed drive fan impeller blade rotation generation to carry out dedusting, because of the easy scaling loss of motor overheating, so motor running time can not be long, be unsuitable for large-area dedusting work.

Summary of the invention

In order to overcome the easy scaling loss of waste water resource, motor overheating, the ineffective deficiency of large tracts of land dedusting that exists in the existing dedusting technology, the utility model provides a kind of suction type deduster that is used for industrial dedusting, this deduster utilizes existing source of the gas of factory or air compressor machine to be power, mechanical rotating part, wearing and tearing are not only not fragile, and do not generate heat, running time is unrestricted, is very suitable for large-area dedusting work.

The technical scheme that its technical problem that solves the utility model adopts is: deduster comprises casing at least, be positioned at the separator and the dust exhaust apparatus that is installed on the cabinet cover of casing, the threeway combination reducer pipe of dust exhaust apparatus is by nozzle, mixing chamber is formed with the carrier pipe that is positioned at mixing chamber one end, nozzle places in the mixing chamber, nozzle is the interior blank pipe of a stairstepping, its internal diameter reduces step by step, nozzle, mixing chamber, carrier pipe respectively with external air source or air compressor machine, sweep-up pipe, the cyclone dust removal chamber of separator is communicated with, the top of separator is gas vent, the bottom is the cyclone dust removal chamber, the whirlwind core is positioned at the cyclone dust removal chamber, the whirlwind in-core is put the two-stage dust removal cloth bag, and the lower end in cyclone dust removal chamber is a dust bag.This deduster utilization threeway combination reducer pipe can produce the characteristic of negative pressure, make complete machine be in negative pressure state, draw dust, sump oil, sewage etc., after dust-contained airflow tangentially enters deduster, can keep rotation at a high speed, ash and air make air-flow separately form vortex pair motion up and down then because of the different centrifugal force of generation of poor quality in the rotary course, and dust is in the strong centrifugation of bottom, cyclone dust removal chamber generation.Be separated to peripheral thicker particle and bring to bottom, dedusting chamber by following vortex, enter dust bag along the periphery; The dust granule that another part is thinner brings to top by last vortex, forms strong Cyclonic dust ring, produces the effect of gathering of particulate, carries out final dusting by the two-stage dust removal cloth bag.

The beneficial effects of the utility model are the power source that uses of this suction type deduster existing source of the gas or air compressor machines as factory, replace conventional cleaners to be used as power with motor, can be energy-conservation, and this machine has adopted the two-stage dust removal mode of cyclone dust removal and cloth-bag type dedusting, efficiency of dust collection can be up to 99% after testing, and this machine mechanical rotating part, do not have wearing and tearing, do not generate heat, running time is unrestricted, is particularly suitable for large-area industrial dedusting work.
