Novel floating sealing structure

Abstract

The invention discloses a novel floating sealing structure, which is arranged in a sealed cavity, and comprises two sealing rings and two synthetic rubber gaskets, wherein the cross sections of the first sealing ring and the second sealing ring are L-shaped, and the first sealing ring and the second sealing ring are assembled face to face by using the L-shaped sides as joint faces; the entire upper part of the first synthetic rubber gasket is tightly jointed with the inside of the L-shape of the first sealing ring, and a side edge of the lower part of the first synthetic rubber gasket is jointed with the inner wall of the sealed cavity; and the entire upper part of the second synthetic rubber gasket is tightly jointed with the inside of the L-shape of the second sealing ring, and one side edge of the lower part of the second synthetic rubber gasket is jointed with the inner wall of the sealed cavity. The invention has the advantages that: 1, the structure is simple; 2, external impurities such as water and dirt are prevented from entering bearings; 3, inside lubricating oil is effectively prevented from leaking; 4, the service life is long; and 5, self-centering can be performed, maintenance is free, and assembly is easy.

Description

technical field [0001] The present invention relates to a sealing structure, in particular to a sealing structure for a horizontal spiral settling discharge centrifuge. Background technique [0002] Horizontal spiral settling discharge centrifuge is a separation machine with high technical content used to separate solid-liquid mixture, which can separate liquid-liquid, liquid-solid, liquid-liquid-solid suspension (turbid liquid) , It has strong adaptability to physical parameters such as material concentration, particle size, temperature, viscosity, etc. It can be used to perform: liquid phase clarification, solid phase dehydration, particle size classification, and material concentration. [0003] The separation principle of the horizontal spiral sedimentation discharge centrifuge is: the material enters the high-speed rotating drum, and under the action of a strong centrifugal force field, the denser the material (such as solid phase) in the suspension is subjected to the ...

Problems solved by technology

In the past, the screw pusher and the wheel shaft at the liquid end were sealed with Buna N material. In the wet ring, water easily entered; and the friction force was large, which easily caused the shaft to wear; it was easy to age, which deteriorated the use and lubrication conditions of the bearing. Cause the deterioration of lubricating oil, or even lose the sealing effect, and dirt enters the bearing, causing the bearing to be damaged
