Description

Technical Field

[0001] The utility model relates to the technical field of disc centrifuges, in particular to a disc-type centrifugal device. Background Art

[0002] Disc centrifuge can separate solid-liquid and liquid-liquid quickly and continuously. It is a type 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. It mainly increases the production capacity of the centrifuge by adding multiple sets of discs to increase solid-liquid or liquid-liquid.

[0003] The utility model patent application document with publication number "CN212018209U" discloses a disc centrifuge with adjustable disc spacing, which is mainly composed of an outer shell, an inner shell, a liquid inlet pipe, a fixed cylinder, a threaded rod, a limit ring, a first thread, a disc and a rubber ring. Through the structure of the outer shell, inner shell, liquid inlet pipe, fixed cylinder, threaded rod, first threaded ring, disc and rubber ring, this technical solution can facilitate the loading and unloading of the outer shell, inner shell and liquid inlet pipe. After disassembly, the position and spacing of the discs on the threaded rod can be adjusted, and the number of discs can be changed, which increases the applicability of this disc centrifuge.

[0004] The disc centrifuge with adjustable disc spacing disclosed in the above-mentioned document has the following defects: when adjusting the disc spacing, it is necessary to first remove the threaded rod from the transmission structure, then remove the liquid inlet pipe, and open the outer shell and the inner shell to remove the structure at the threaded rod. After that, the discs can be rotated to adjust the position of the discs on the threaded rod and the spacing between them. When adjusting the spacing between the discs, the steps are relatively cumbersome, which indirectly reduces work efficiency and has poor practical effect.

[0005] It can be seen from this that the existing disc centrifuge does not have a good structure for adjusting the disc indirectly, and it is necessary to improve the existing shortcomings and provide a disc centrifugal device. Utility Model Content
