Abstract

The utility model relates to the technical field of large-size low-speed rotary sealing structures, in particular to a rotary sealing structure which can realize the sealing property of the connection of a stirring container and a vacuum cover and ensure the service life.

Description

Rotary sealing structure

Technical Field

The utility model relates to the technical field of large-size low-speed rotary sealing structures, in particular to a rotary sealing structure.

Background

In chemical industry stirring industry, such as lithium electricity, medicine, gluing agent etc, need put into stirred vessel with the thick liquids and stir, traditional stirred vessel is after pouring the material into, it is fixed with agitating unit's vacuum hood to be promoted, gear box on the agitating unit drives stirring rake revolution and rotation and stirs the material, when stirred vessel is great, a stirring structure has now been designed, the stirring rake only rotates, stirred vessel rotates and accomplishes the stirring to the material, current single use jumbo size oil blanket, because the gyration precision can not reach the requirement and produce the vacuum leakage, perhaps oil blanket lip limit excessive contact wear, thereby the life-span reduces.

Disclosure of Invention

In order to solve the problem that the existing stirring container cannot realize good sealing when rotating and the service life is influenced, the utility model provides a rotary sealing structure which can realize the sealing performance of the connection between the stirring container and a vacuum cover and ensure the service life.

The technical scheme is as follows: the utility model provides a vacuum cover seal structure, its includes stirred vessel and vacuum cover, its characterized in that, the vacuum cover bottom is provided with the flange under the round, stirred vessel upper end is provided with the flange on the round, go up the flange with be provided with oil blanket and roller between the flange down.

The vacuum stirring device is further characterized in that the rollers are mounted on the inner side surface of the lower flange, when the stirring container is connected with the vacuum cover, the upper flange is positioned on the inner side of the lower flange, and the rollers are in contact with the peripheral surface of the upper flange;

and the oil seal is arranged between the inner side surface of the lower flange and the outer side surface of the upper flange, and a gap is reserved between the upper end of the upper flange and the lower flange.

Eight groups of rollers are uniformly arranged on the inner side of the lower flange.

After the rotary sealing structure is adopted, the roller and the oil seal are arranged between the upper flange and the lower flange, the rotary sealing structure realizes the effect of combining large-size rotary sealing and auxiliary rotary support, the oil seal is well matched with a container, the sealing effect is ensured, and meanwhile, the service life of the oil seal is ensured.

Drawings

FIG. 1 is a schematic structural view of the present invention;

FIG. 2 is an enlarged view of the point A in FIG. 1;

fig. 3 is a schematic view of a roller arrangement.

Detailed Description

Referring to fig. 1, 2 and 3, the vacuum cover sealing structure comprises a stirring container 1 and a vacuum cover 2, wherein a circle of lower flange 3 is arranged at the bottom of the vacuum cover 2, an upper flange 4 is arranged at the upper end of the stirring container 1, and an oil seal 5 and a roller 6 are arranged between the upper flange 4 and the lower flange 3.

Specifically, eight groups of rollers 6 are arranged on the inner side surface of the lower flange 3, when the stirring container 1 is connected with the vacuum cover 2, the upper flange 4 is positioned on the inner side of the lower flange 3, and the rollers 6 are in contact with the outer peripheral surface of the upper flange 4, so that the stirring container 1 can realize reliable rotation, and a plurality of rollers 6 can be arranged and fixed on the mounting seat 7 in an arc shape; and an oil seal 5 is arranged between the inner side of the lower flange 3 and the outer side of the upper flange 4 above the roller 6, a gap is reserved between the upper end of the upper flange 4 and the lower flange 3, and reliable sealing is realized through the oil seal 5.

Claims

1.
