Description

Spiral dust collector falls in slope
Technical Field
The invention relates to the technical field of dust removing equipment, in particular to a slope-descending spiral dust removing device.
Background
In industrial production, a large amount of dust can be generated in some occasions, the health of operators can be influenced when the operators work in the occasions for a long time, and meanwhile, the environment can be polluted by directly discharging air with the dust to the outside, which is particularly prominent in the coal transportation industry. At present, a large amount of dust is generated in the transportation process of a conveying belt of coal, especially in the process of transporting the coal from one belt to the other belt, the large amount of dust is stirred up due to the falling of the large amount of coal, the dust is diffused in a production workshop, great harm is caused to the body of workers in an operation area, meanwhile, the production safety is also influenced by the large amount of coal powder in the air, and the deflagration risk is generated at any time; meanwhile, coal water formed by mixing coal powder and water is corrosive, a method of directly adopting dry fog for dust suppression on equipment cannot play a role in removing dust fundamentally, but generates a plurality of coal water drops to corrode the surface or the whole structure of the equipment, and one conveying belt is corroded almost completely in a period of several years. Therefore, the dust removing device is suitable for transportation, and after dust-carrying air generated in a working place is sucked into the dust removing device, dust in the dust removing device can be blocked in the dust removing device, and pure air is discharged to the outside. However, the existing dust removal device is not suitable for large-size dust removal devices because the length of a dust removal processing channel is simply increased in order to improve the dust removal effect, so that the device has large horizontal and vertical sizes, and more dust removal positions are needed in working scenes such as coal transportation.
