Description

Technical Field

[0001] The invention relates to the technical field of coal mine dust removal, and in particular to a mine dust removal device. Background Art

[0002] Coal mines are areas where humans mine coal resources in coal-rich mining areas. They are generally divided into underground coal mines and open-pit coal mines. When the coal seam is far from the surface, people usually choose to dig tunnels underground to mine coal. This is an underground coal mine. When coal mines are being mined, a lot of dust will be generated. Most of the existing dust removal devices use wet dust removal, which is to add more water to the ground to reduce the dust during coal mining. However, this will cause more water on the ground, affecting the collection of coal mines and causing the coal mines to become damp. Summary of the invention

A filter element is arranged inside the filter tube main body, and a fixing hoop is fixedly connected on the outer tube wall of the filter tube main body extending to one end of the first connecting sleeve and the second connecting sleeve, and the filter tube main body is rotatably connected with the first connecting sleeve and the second connecting sleeve. The driving member arranged inside the driving box can drive the fan blades to rotate. When the fan blades rotate, negative pressure can be formed inside the driving box. The air containing dust is sucked into the driving box from the dust collection component. The air containing dust will be filtered for the first time when entering the filter tube body, and will be filtered for the second time when passing through the driving box. The air after multiple filtrations will be discharged from the clean air exhaust hole to complete the dust removal process.

[0005] Furthermore, the upper cylinder is threadedly connected to the lower cylinder, which is convenient for disassembly to replace the filter plate and other components.

[0006] Further, the filter plate is located above the fan blades, the filter plate is installed inside the upper cylinder, and the filter plate is connected to the side wall of the inner circle of the upper cylinder. In this solution, it is fixedly connected and located above the fan blades, and the filtering effect is better.

[0008] Furthermore, a truncated cone-shaped support column is sleeved on the bottom of the servo motor to achieve the purpose of support and ensure stability.

[0009] Furthermore, the truncated cone-shaped support column is fixedly connected to the inner bottom wall of the lower cylinder, and the side wall of the outer circle of the truncated cone-shaped support column is inclined, which can facilitate the discharge of air.

[0010] Furthermore, a heat dissipation groove is provided at one end of the lower cylinder close to the truncated cone-shaped support column, and the heat dissipation groove is connected to the interior of the lower cylinder, so that the servo motor can be cooled, thereby extending the service life of the servo motor.

[0011] Furthermore, the filter tube body is made of rubber material. The rubber tube has good flexibility and can be bent, which is convenient for replacing the filter tube.

When the fan blades rotate, negative pressure can be formed inside the driving box. The dusty air is sucked into the driving box from the dust suction component. The dusty air will be filtered for the first time when entering the filter tube body, and will be filtered for the second time when passing through the driving box.
