Water film dust removal device for treating dust generated by sand blasting machine

Abstract

The invention discloses a water film dust removal device for treating dust generated by a sand blasting machine. The water film dust removal device comprises a barrel, a dust inlet pipeline, a water spray nozzle, a water inlet pipe, porous disc-shaped thin plates and an accumulated dust outlet device. The dust enters the barrel through the dust inlet pipeline, and the water spray nozzle supplies water through the water inlet pipe to achieve water spray purification on the dust; the porous disc-shaped thin plates are of an upper-lower layer structure and are welded to the inner wall of the barrel to form a curve type pipeline; six air outlet holes are formed in an upper cover of the barrel, and the lower end of the barrel is fixedly connected with the accumulated dust outlet device; air obtained after water spray purification of the water spray nozzle is secondarily purified through the curve type pipeline formed by the upper-lower layer porous disc-shaped thin plates and then is discharged through the six air outlet holes in the upper cover of the barrel; and accumulated dust obtained after water spray purification of the water spray nozzle falls to the lower end of the barrel, theaccumulated dust outlet device at the lower end of the barrel is opened, and cleaning and discharging of the accumulated dust are achieved. The device solves the problems that due to a large amount of dust generated during work of the sand blasting machine, air pollution is caused, and the work environment is severe, and has the beneficial effects of low treatment cost, low material consumption and high efficiency.

Description

technical field [0001] The invention belongs to the field of industrial dedusting devices, in particular to a water film dedusting device for processing dust generated by sandblasting machines. Background technique [0002] At present, environmental protection issues in the industrial production process cannot be ignored. In the process of mechanical manufacturing, when sandblasting is performed on the surface of the workpiece, a large amount of polluting dust will be generated in the sandblasting machine. Pollution dust will be discharged directly from the outlet of the sandblasting machine, causing serious air pollution, and causing a bad working environment, and the staff need to wear protective clothing. The existing dust removal technologies are mainly bag dust removal, spray dust removal, and water wall dust removal. Although the bag dust removal has a high dust removal rate, its efficiency is not high and requires regular maintenance and replacement of consumables; ...

Problems solved by technology

The polluting dust will be discharged directly from the outlet of the sandblasting machine, causing serious air pollution and harsh working environment. Staff need to wear protective clothing

The existing dust removal technologies are mainly bag dust removal, spray dust removal, and water wall dust removal. Although the bag dust removal has a high dust removal rate, its efficiency is not high and requires regular maintenance and replacement of consumables; The water mist is sprayed out and cannot be in good contact with the dust surface, thereby reducing the efficiency of dust removal; the water wall surface dust removal method is to distribute the water flow in the dust pipe, which cannot fully purify the dust, but can only purify the dust in contact with the water wall surface. And the dust inside cannot be fully purified
