Problems solved by technology

After the material leaves the drum through centrifugation, it flows out from the discharge port. There must be a section of the main shaft exposed between the drum and the bearing cover, so the anti-corrosion of this part of the main shaft has become the main problem of the clean centri

Abstract

The invention relates to a sealing device for a centrifuge main shaft. The sealing device comprises a main shaft, a bearing block cover plate arranged on a bearing block of the main shaft, a drum, and a sealing assembly for sealing the clearance between the bearing block cover plate and the drum on the main shaft; the sealing assembly comprises a sealing base arranged on the bearing block cover plate, a spring arranged on the sealing base, an upper sealing ring arranged on the drum, and a sealing sleeve positioned between the sealing base and the upper sealing ring; and the lower surface of the sealing sleeve is in static sealed fit with the sealing base through the sealing ring, and the upper surface of the sealing sleeve is in dynamic sealed fit with the upper sealing ring through the spring. The sealing device can effectively separate a material and the main shaft and prevent material pollution and main shaft corrosion.

Description

technical field [0001] The invention relates to a sealing device, in particular to a sealing device for the main shaft of a centrifuge. Background technique [0002] A centrifuge is a device that uses the principle of centrifugal separation to separate the suspended material into solid and liquid. A centrifuge has a cylinder, called a bowl, that rotates at high speed about its own axis, usually driven by an electric motor. After the suspension (or emulsion) is added to the drum, it is quickly driven to rotate at the same speed as the drum, and the components are separated under the action of centrifugal force and discharged separately. Generally, the higher the drum speed, the better the separation. [0003] With the continuous development of the chemical, pharmaceutical, and food industries, various materials emerge in endlessly, and the requirements for separation and filtration equipment are also increasing. improve. From manufacturing precision to material selection,...
