Background
The disk centrifuge is a vertical centrifuge, and a rotary drum is arranged at the upper end of a vertical shaft and is driven by a motor through a transmission device to rotate at a high speed. The drum is provided with a group of disk-shaped parts, namely disks, which are mutually sleeved together. A small gap is left between the disks. The suspension (or emulsion) is fed into the drum through a feed pipe located in the center of the drum. As the suspension (or emulsion) flows through the gaps between the discs, the solid particles (or droplets) settle by the centrifuge onto the discs to form a sediment (or liquid layer). The sediment slides along the surface of the disc to be separated from the disc and is accumulated at the part with the largest inner diameter of the rotary drum, and the separated liquid is discharged out of the rotary drum from the liquid outlet. The disc is used for shortening the settling distance of solid particles (or liquid drops) and expanding the settling area of the rotary drum, and the production capacity of the separator is greatly improved due to the disc arranged in the rotary drum. The solids accumulated in the drum are removed manually by disassembling the drum after the separator is shut down, or discharged from the drum through a slag discharge mechanism without shutting down the separator.
In the existing disc centrifuge, when the drum device works, axial movement can be generated between the drum body and the working piston, and the drum body and the working piston are metal parts, so that collision can be generated during movement inevitably, and abrasion of parts is caused, and the service life is influenced.
