Description

Technical Field

[0001] The utility model relates to the technical field of dust removal devices, in particular to an AMPS granulation dust removal device. Background Art

[0002] AMPS (2-Acrylamido-2-Methylpropanesulfonic Acid) is an acrylamide-based anionic monomer, present as a white crystalline solid. AMPS is synthesized primarily from acrylonitrile, isobutylene, and fuming sulfuric acid. Fuming sulfuric acid is added to a mixture of acrylonitrile and isobutylene, and the resulting product is directly reacted in the presence of various additives. It is primarily used in industries such as the petroleum industry, water treatment, synthetic fiber, and papermaking.

[0003] The powdered AMPS product from the desiccant is put into the product silo and enters the elevator through the silo feeding auger. The material is then transferred to the degassing silo through the elevator. The degassed material is forced to be pressed by the forced feeding auger until the dry roller press presses the product into a 5mm cake. The particle size distribution of the material particles is controlled by adjusting the speed of the crusher. The crushed AMPS product has powder and particles of different diameters. It is screened through a swing screen and the qualified particle size products are packaged. The remaining powder and the AMPS product of unqualified particle size are then mixed through the return auger, the elevator and the powdered AMPS products from the dryer into the degassing silo and then compressed and granulated.

The upper end of the upper guide rod 8 extends upward through the upper guide hole. A drive ring 7 is fixedly connected between the upper ends of the two upper guide rods 8.

[0035] A compression spring 13 is sleeved on the lower guide rod 11 , and two ends of the compression spring 13 respectively abut against the upper surface of the limiting plate 12 and the lower surface of the bottom plate 16 .

[0036] The upper end of the top plate 15 is fixedly connected to a feed cylinder 6 which is in communication with the inner cavity of the dust removal cylinder. The feed cylinder 6 is located in the inner hole of the drive ring 7 .

[0037] The upper end of the mesh cylinder 2 is fixedly connected with a conical diversion cover 5.
