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

The invention discloses a water film dedusting device for treating dust generated by a sandblasting machine, which comprises a cylinder body, a dust inlet pipe, a water spray nozzle, a water inlet pipe, a porous disc-shaped thin plate and a dust accumulation outlet device. Dust enters the cylinder through the dust inlet pipe, and the water nozzle is supplied with water through the water inlet pipe to realize the water spray purification of the dust; the porous disc-shaped thin plate has an upper and lower structure, which is welded to the inner wall of the cylinder to form a curved pipeline; The cover is equipped with six air outlets, and the lower end is fixedly connected to the dust accumulation outlet device; the air purified by spraying water from the water nozzle is purified twice through the curved pipeline formed by the upper and lower porous disc-shaped thin plates, and then passes through the upper cover of the cylinder. Six air outlets are discharged; the accumulated dust purified by spraying water from the water nozzle falls to the lower end of the cylinder, and the dust accumulation outlet device at the lower end of the cylinder is opened to realize the cleaning and discharge of the accumulated dust; Dust causes air pollution and poor working environment, and has the advantages of low processing cost, less consumables, 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; ...
