Description

Disk rack inlet air isolation device for butterfly separator

Technical Field

The utility model belongs to the technical field of centrifuge, concretely relates to dish rack import isolated air device for butterfly separator.

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 butterfly-type separating centrifuge in the past can get into the air because material and plate rail for often produce a large amount of foams at the discharge gate in the in-process of stirring production, influence the separation effect.
