Technical Field

[0001] The invention relates to the technical field related to grinding roller processing, in particular to a dust removal device for a grinding roller processing workshop. Background Art

[0002] In roller processing workshops, although traditional dust removal devices can handle dust in the air to a certain extent, they still have significant technical defects in practical applications. These devices usually rely on complex filtering systems and dust collection devices to separate dust and air, but this method often cannot completely solve the problem of dust adsorption, especially under the action of static electricity, a large amount of fine dust will still adhere to the surface of the electrostatic equipment. In addition, traditional dust removal devices are easily damaged in high temperature environments and have high maintenance costs.

[0003] With the increasingly stringent environmental protection requirements, how to effectively recycle and utilize these adsorbed dust has become an urgent problem to be solved. Most of the existing dust removal methods can only separate dust from the air, but it is difficult to further process the dust that has settled or adsorbed on the surface. This not only causes a waste of resources, but also may cause secondary pollution to the working environment. For this reason, we propose a dust removal device for roller processing workshops.

The rotating brush ring can clean the surface of the electrostatic rod, thereby improving the cleaning effect of the dust on the surface of the electrostatic rod. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] See also Figure 1 - Figure 7 The embodiment of the present invention provides a technical solution: a dust removal device for a grinding roller processing workshop, comprising a dust removal tank 1, an air inlet pipe 11 and an exhaust pipe 12 are fixedly installed at both ends of the outer wall of the dust removal tank 1, a plurality of electrostatic rods 13 distributed in a circular array are fixedly installed at equal intervals in the dust removal tank 1, a dust collecting plate 2 is arranged in the dust collection tank 1, a limit plug hole 23 connected with the electrostatic rod 13 is opened at the lower end of the inner cavity of the dust collection plate 2, a through cavity 24 is opened at the upper end of the inner cavity of the dust collection plate 2, and the through cavity 24 is arranged on the limit plug hole 23. On the upper side of the hole 23, the inner wall of the through cavity 24 is gap-matched with the outer periphery of the electrostatic rod 13, a threaded rod 25 is rotatably installed in the dust removal tank 1, and a threaded hole 21 threadedly connected to the threaded rod 25 is opened in the middle of the dust collecting plate 2, a driving motor 28 is fixedly installed on the upper end of the dust removal tank 1, and the output shaft of the driving motor 28 is connected to the threaded rod 25, and a dust exhaust pipe 31 is fixedly installed on the upper end of the dust removal tank 1, a telescopic tube 32 is provided in the threaded rod 25, and the lower end of the telescopic tube 32 is fixedly connected to the upper end of the dust collecting plate 2.

[0031] Working principle: During the roller processing, the air in the workshop can be guided into the dust removal tank 1 through the air inlet pipe 11, and the air can be discharged to the outside through the exhaust pipe 12, and the electrostatic rod 13 is started. When the air passes through the dust removal tank 1, the static electricity generated by the electrostatic rod 13 can adsorb the dust in the air;

[0032] When it is necessary to recycle the dust on the surface of the electrostatic rod 13, the dust exhaust pipe 31 is connected to the external air pump, the external air pump and the drive motor 28 are started, and the air inlet pipe 11 and the exhaust pipe 12 are opened. The output shaft of the drive motor 28 can drive the threaded rod 25 to rotate. The electrostatic rod 13 is connected to the limit socket 23 through the plug connection between the electrostatic rod 13 and the limit socket 23 to limit the movement direction of the dust collecting plate 2. The rotating threaded rod 25 can drive the dust collecting plate 2 to move from bottom to top in the dust removal tank 1 through the threaded connection between the electrostatic rod 13 and the threaded hole 21. Therefore, the dust on the surface of the electrostatic rod 13 can be guided into the dust collecting plate 2 through the pressure difference between the inside and outside of the through cavity 24, and then the dust can be discharged outward through the telescopic tube 32 and the dust exhaust pipe 31, so as to achieve the effect of cleaning the dust on the surface of the electrostatic rod 13.
