Description

Technical Field

[0001] The utility model relates to the technical field of silo filter cartridge cleaning devices, and more specifically to an automatic cleaning mechanism for a powder material silo filter cartridge return device. Background Art

[0002] During the feeding process of powder materials, dust is easily accumulated on the surface of the silo filter cartridge return device, which needs to be cleaned regularly.

[0003] After searching, the existing announcement number CN218249168U is a filter element dust removal filter cartridge, which includes a filter cartridge body and a filter element installed inside the filter cartridge body. The inner wall of the filter cartridge body is rotatably connected with four sets of rotating plates, and the outer walls of the four sets of rotating plates are fixedly connected with cleaning layers corresponding to the filter element, and the outer walls of the four sets of rotating plates are fixedly connected with gear rings; it also includes a driving component that drives the gear ring to rotate at the axis of the filter element. By turning on the driving motor to drive the rotating shaft and the rotating gear to rotate, the rotating gear is meshed with the gear ring, thereby driving the four sets of rotating plates and the four sets of cleaning layers to rotate. The cleaning layer can clean the surface of the filter element, achieving the effect of automatic cleaning. This operation method is more time-saving and labor-saving, reduces the workload of the equipment, and enhances the cleaning efficiency of the device.

[0004] The existing powder material silo filter cartridge return device has material viscosity problems and wrinkles in the filter cartridge, which causes material to accumulate outside the filter cartridge, resulting in a series of abnormalities such as the filter cartridge pressure difference alarm. The existing filter cartridge air bag backflush technology cannot clean the filter cartridge, and manual intervention is required to regularly use a compressed air gun to blow and clean it. Therefore, we propose an automatic cleaning mechanism for the powder material silo filter cartridge return device to solve the above problems. Utility Model Content
