Various embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

Embodiment 1. The present invention is a centrifugal high-stability dust removal and environmental protection equipment for mining. As shown in Figures 1-15, it includes a square outer cylinder 1 and a cylinder cover 2. The bottom of the outer cylinder 1 is installed. There are moving wheels to facilitate moving the device. The top of the cylinder cover 2 is penetrated and fixedly installed with a dust suction pipe 201. The dust suction pipe 201 is connected to a dust suction fan, which can suck dust in the environment into the interior of the outer cylinder 1. A dust removal cylinder plate 3 with a circular hole running through the middle part of the outer cylinder 1 is fixedly installed between the inner walls of the outer cylinder 1. A dust removal mesh cylinder 4 with the same inner diameter as the circular hole is fixedly installed on the top surface of the dust collection cylinder plate 3. The dust removal mesh cylinder 4 Able to filter dust, a filter with a smaller aperture can be used. A centrifugal rod 5 is rotatably installed in the middle of the cylinder cover 2, and a plurality of dust-removing mesh cylinders 4 are fixedly installed on the outer surface of the centrifugal rod 5. The centrifugal fan blades 6 and the dust suction pipe 201 inhale the dust-containing air from the outside into the dust removal mesh cylinder 4. At the same time, the centrifugal rod 5 can drive multiple centrifugal fan blades 6 to rotate inside the dust removal mesh cylinder 4, so that the inside of the dust removal mesh cylinder 4 The air generates eddy currents, and the centrifugal force generated by the eddy current drives the dust to quickly move to the dust removal mesh cylinder 4 and filters the dust, thereby improving the dust removal efficiency. A filter 101 is installed on the outer surface of the outer cylinder 1, and the air passes through the dust removal mesh cylinder 4 After filtration, it can be discharged from the filter screen 101, thereby completing the air circulation, filtration and dust removal. A scraper ring 7 located above the centrifugal fan blade 6 is coaxially fixed on the outside of the centrifugal rod 5, and the centrifugal rod 5 can drive the scraper ring. 7 rotates synchronously. A plurality of scraper beams 8 are fixedly installed on the outer surface of the scraper ring 7. The bottom surface of the scraper beam 8 is in contact with the top of the dust removal mesh cylinder 4. When the scraper ring 7 rotates, it can Each scraper beam 8 moves circumferentially on the top of the dust removal screen barrel 4. The bottom of each scraper beam 8 is fixedly installed with a spiral scraper 9 that fits the inner side of the dust removal screen barrel 4. Multiple scrapers When the beam 8 moves in a circumferential direction, it can drive a plurality of spiral scrapers 9 to move in a circumferential direction.

Multiple scraper beams 8 can drive multiple air blast mechanisms 12 to move circumferentially around the dust removal screen cylinder 4. When the dust removal screen When the mesh of the dust collector 4 is clogged with dust, multiple air blasting mechanisms 12 can blow out high-pressure gas to the dust collector 4, thereby blowing the dust clogged inside the mesh of the dust collector 4 to the inside of the dust collector 4, and then spirally The scraper 9 can scrape the dust down to the bottom of the outer cylinder 1. A unloading device 13 is installed between the front and rear inner walls of the outer cylinder 1. After the spiral scraper 9 scrapes the dust on the inside of the dust removal mesh cylinder 4, the dust can be removed. Fall to the unloading device 13, and then move the dust to the bottom of the outer cylinder 1 for storage through the unloading device 13. The unloading device 13 can seal and isolate the interior of the outer cylinder 1 into upper and lower parts to avoid centrifugal fan blades 6 During the rotation, the dust that has been scraped into the space below the unloading device 13 is again driven to the inside of the dust collector 4 for filtration, causing more and more dust inside the dust collector 4.
