Description

Technical Field

[0001] The utility model relates to a disc centrifuge component, in particular to a disc piece combination structure of a disc centrifuge. Background Art

[0002] Disc centrifuge can separate solid-liquid and liquid-liquid quickly and continuously. It is a kind of vertical centrifuge. The drum is installed on the upper end of the vertical shaft and is driven by an electric motor through a transmission device to rotate at high speed. Among them, a group of discs stacked on each other are installed in the drum. The suspension or emulsion is added to the drum through a feed pipe located in the center of the drum. When the suspension or emulsion flows through the gap between the discs, the solid particles or liquid droplets settle on the discs under the action of the centrifuge to form sediment or liquid layer. The sediment slides along the surface of the disc and detaches from the disc and accumulates in the part with the largest diameter in the drum. The separated liquid is discharged from the drum from the liquid outlet. The function of the disc is to shorten the sedimentation distance of solid particles or liquid droplets and expand the sedimentation area of ​​the drum. The installation of discs in the drum greatly improves the production capacity of the separator.

[0003] The existing disc assembly structure includes a feed pipe and a plurality of discs sleeved on the feed pipe. However, the position of the discs on the feed pipe is fixed and cannot be adjusted, so that the spacing between adjacent discs cannot be flexibly adjusted according to the actual needs of the separation medium.
