[0032] It should be noted that the dust removal device is used for green and environment-friendly pigment production, and in specific work,

[0033] (1) Pigment production, start the grinder 11 to process the material, the material between the intense friction, collision produces a large amount of dust. The sealing box structure of the mounting frame 1 creates a closed space, reduces the spread of dust to the workshop environment. The heating structure 12 from the bottom to meet the requirements of uniform temperature of pigment grinding, improve the grinding quality; The opening of the gas hood 5 has low air flow rate, while the grinder 11 works to make the local air density increase due to the mixing of dust, forming a pressure difference.

As the airflow continues to rise, smaller dust particles are sequentially intercepted by the upper layer of the dust filter screen 3 with gradually decreasing pore size. The intercepted larger dust particles directly fall into the dust collection tank 4 due to gravity, and the smaller particles are adsorbed on the dust filter screen 3. Open the second switch door 22, pull out the dust filter screen 3, which can be cleaned to restore its filtering performance. After being filtered by the multi-layer dust filter screen 3, the dust content of the gas is greatly reduced, and the gas is discharged from the gas outlet hole 24 on the top wall of the box, meeting the environmental protection emission standard. The dust in the dust collection tank 4 is periodically discharged by manually opening the dust discharge pipe.
