Description
Technical Field
The invention belongs to the technical field of material separation, and particularly relates to a disk centrifuge with a low-cost mounting structure.
Background
The disc separator 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.
The slag discharge mode of the disc separator is as follows: the automatic deslagging device has three structures of manual operation, automatic operation and nozzle, wherein the automatic deslagging is widely applied, the working piston is used for deslagging automatically, the principle of the automatic deslagging device is that the working piston moves up and down through a special structure, the working piston moves up during working to form a closed cavity, materials are separated in the closed cavity, and when slag is accumulated to a certain degree and needs to be discharged, the working piston moves down to remove the slag and part of liquid is discharged out of a rotary drum, so that the automatic deslagging is realized.
The defects of the prior disc separator are as follows: the rotary drum cover is pressed tightly on the rotary drum body through the main lock ring, and the support part for manufacturing the rotary drum cover needs to be additionally processed when the rotary drum body is processed, so that the processing cost of the rotary drum body is increased.
