Description

Technical Field

[0001] The present invention belongs to the field of calcium carbonate production, and specifically refers to a dust regeneration device for calcium carbonate production screening. Background Art

[0002] Calcium carbonate, as an important industrial raw material, is widely used in fields such as building materials, chemical engineering, and medicine. In the production process, the screening of calcium carbonate debris and dust treatment are key links. Traditional screening technologies mostly use vibrating screens or manual screening, with low efficiency and easy to cause dust pollution. In recent years, with the improvement of environmental protection requirements, dust recovery technologies have gradually received attention, but existing technologies often have problems such as low screening efficiency and dust clogging of filter plates, and urgent improvement is needed.

[0003] Currently, calcium carbonate screening mainly adopts the vibrating screening method, which realizes screening through mechanical vibration, but has high noise, high energy consumption, and easy dust escape. Moreover, during the screening process, calcium carbonate dust accumulates on the upper part of the filter mesh, easily causing blockage and affecting the screening efficiency; some factories use electrostatic dust removal equipment, which can effectively collect dust, but the equipment is complex, costly, and has limited screening effect on calcium carbonate debris. Summary of the Invention

The fixed end of the electric telescopic rod is fixedly connected to the inner side of the dust collection bin, the end of the movable end of the electric telescopic rod is fixedly connected to the brush, and the brush is in a brushing connection with the first filter plate.

[0011] Furthermore, the material guiding plates are all arranged in parallel.

[0012] Furthermore, the lower part of the dust collecting bin is set as a storage bin, and the bottoms of the separation gaps at the connections between the material guiding plates and the box body are all set as storage bins, and the storage bins are communicated with the discharge port.

[0013] Furthermore, a baffle plate is fixedly arranged on the lower side of the upper material guiding plate, and the baffle plate is located directly above the storage bin.

[0014] Furthermore, the cleaning mechanism includes a motor, a lead screw, a guide rod and a brush plate.

The guide plates 4 are all arranged in parallel. The lower part of the dust collection bin 2 is set as a storage bin 104. The bottom of the separation gap at the connection between the guide plates 4 and the box body 1 is all set as the storage bin 104. The storage bin 104 is communicated with the discharging port 102. A baffle plate 403 is fixedly arranged on the lower side of the upper guide plate 4. The baffle plate 403 is located directly above the storage bin 104 and is used to discharge the filtered calcium carbonate fragments to the upper part of the lower filter plate 402.

[0028] As Figures 1-4As shown in the figure, the cleaning mechanism 5 is respectively arranged above the upper filter plate 401 and the lower filter plate 402. The cleaning mechanism 5 includes a motor 501, a lead screw 502, a guide rod 503 and a brush plate 504. The motor 501 is fixedly arranged on the side of the box body 1 and is located inside the dust collection bin 2.
