Dust is easily generated during the operation of Raymond mill, and the dust generated during the operation of Raymond mill needs to be handled in time.
[0003] After searching, the utility model patent with announcement number CN217190190U discloses a dust removal device for Raymond mill, including a dust removal box and a dust collecting box. The side end of the dust collecting box is connected to the dust removal box, the dust removal box includes a box body, a dust removal plate and a box cover. A box body is installed on one side of the dust collecting box, and multiple groups of dust removal plates are arranged inside the box body. The upper end of the dust removal plate is also connected to the box cover. The dust collecting box includes an air pump, a connecting screw, a discharge pipe and a discharge head. Through the limit groove and the limit frame plate structure, it is convenient to limit the installation of multiple groups of dust removal plates inside the box body, and the dust gas discharged from the pressure equalizing exhaust pipe can be filtered multiple times. Through the limit groove and the discharge hole structure, the box body is convenient for disassembly, assembly, connection and cleaning and maintenance of the dust removal plate and the conveying pipe, so as to avoid the influence of sediment on the permeability of the pressure equalizing exhaust pipe. With the sealing inner ring structure, dust can be prevented from leaking and spraying out from the connection gap of the pipe.
