Compound sealing structure with backup function for rotary main shaft of industrial washing machine

Abstract

The invention relates to a compound sealing structure with a backup function for a rotary main shaft of an industrial washing machine. The structure of a sealing body, the structure of a framework oil seal press plate and the structure of a shaft housing in the prior art are changed; original three lip framework oil seal are reduced to one; two V-shaped sealing rings and two backup V-shaped sealing rings are provided; and the O-shaped ring seal is applied between the sealing body and a back plate of an outer cylinder body of a washing room and between a shaft housing and a rotary main shaft. The structure has the advantages of greatly improving the service life of the sealing structure, realizing the designed service life of the whole machine, not causing any harmful wear to the core component of the machine-main shaft, avoiding the influence of micro radial run-out of the main shat on the sealing structure when the industrial washing machine works, and greatly simplifying huge workload needed for the maintenance and the replacement of the sealing structure, and prolonging the service life of the whole machine.

Description

technical field [0001] The invention relates to an industrial washing machine, in particular to a sealing structure of a rotary main shaft of a fully automatic industrial washing machine with a high-speed dehydration function. Background technique [0002] Industrial washing machine is a kind of washing equipment suitable for star hotels, hotels, hospitals, large enterprises and institutions (such as railways, aviation, mining) and washing and dyeing industry factories to wash large quantities of textile materials. Since the 1970s, my country has been involved in the manufacture of industrial washing machines. With the rapid development of the national economy, the Chinese market has increasingly high requirements for the product technology and quality of industrial washing machines. The sealing technology of the rotating shaft is one of the core technologies of industrial washing machines, which is directly related to the service life and maintenance services of the whole m...

Problems solved by technology

[0006] 2. Affect the service life of the whole machine

The main shaft is the core component of the industrial washing machine, and the wear of its sealing surface will directly cause the machine to fail to seal the water in the washing room, so that the machine cannot work

[0007] 3. When the washing room is dehydrating at a high speed, there must be an eccentric load centrifugal force generated by the uneven distribution of the washed materials in the washing room. The service life of the skeleton oil seal is greatly shortened

[0008] 4. Maintenance and replacement are cumbersome

The structure of industrial washing machine (see attached figure 2 ), using the sealing structure 8 of the lip-shaped skeleton oil seal, when the machine needs to replace the lip-shaped skeleton oil seal, the front and rear bearing seats (9, 10) and the pulley 11 on the main shaft 6 need to be disassembled, and the workload is large and serious Affect the service life of other components such as bearings on the main shaft
