Abstract

The invention discloses a composite sealing device for a centrifugal machine bearing. The composite sealing device comprises a transmission cover (2), an outer bearing cover (3), a bearing seat (4), a bearing (5), an inner bearing cover (6), a sealing bracket (7) and a sealing gland (8) which are sequentially sleeved outside a centrifuge drum spindle (1); and a sealing element (9) is arranged between the sealing bracket (7) and the drum spindle (1), an airtight sealing passage (7.1) is arranged on the sealing bracket (7), the inner end of the airtight sealing passage (7.1) is pressed close to the outer surface of the drum spindle (1) and is located between the sealing element (9) and the sealing gland (8), and the outer end of the airtight sealing passage (7.1) is connected with a high-pressure air source (10). The composite sealing device provided by the invention can effectively prevent such harmful substances as ultra-fine hard powder, corrosive gas and the like from entering the bearing, and belongs to the technical field of the sealing device.

Description

technical field [0001] The invention belongs to the technical field of sealing devices, in particular to a centrifuge bearing sealing device. Background technique [0002] The centrifuge uses the principle of centrifugal separation to send the suspension into the drum through the feed pipe and the screw outlet. Under the action of centrifugal force generated by high-speed rotation, the solid phase particles with a larger specific gravity are deposited on the inner wall of the drum and interact with the drum. The relative moving helical blades continuously scrape off the solid phase particles deposited on the inner wall of the drum and push them out of the slag outlet. The separated clear liquid flows out of the drum through the opening of the liquid layer regulating plate. [0003] With the rapid development of industrial technology and the continuous expansion of the application industry of centrifuges, the requirements of modern industry for industrial centrifuges are bec...
