Large-axial-movement double-end-face mechanical sealing device for rake type dryer

Abstract

The invention relates to a large-axial-movement double-end-face mechanical sealing device for a rake type dryer. The device comprises a shaft sleeve, a medium end static ring seat and an atmosphere side static ring seat are arranged on the shaft sleeve, a sealing seat is installed between the medium end static ring seat and the atmosphere side static ring seat, a corrugated pipe is installed at the left end of the shaft sleeve, a medium end flange is installed at the left end of the corrugated pipe, the medium end flange is connected with the medium end static ring seat through a screw, a single-end-face sealing assembly is arranged on the inner side of the medium end flange, a medium end sealing assembly and an atmosphere end sealing assembly are arranged on the shaft sleeve on the right side of the medium end static ring seat, and the medium end sealing assembly and the atmosphere end sealing assembly are both located on the inner side of the sealing seat. According to the large-axial-movement double-end-face mechanical sealing device for the rake type dryer, the axial movement amount can be increased through the corrugated pipe, then the movement requirement of the rake type type can be met, and dust in a medium can be prevented from entering the sealing face of a double-end-face mechanical sealing device through the single-end-face sealing assembly arranged at the medium end.

Description

technical field [0001] The invention relates to the technical field of machine rotary sealing, in particular to a large axial movement double-end mechanical sealing device for a rake dryer. Background technique [0002] The rake dryer is based on the technology of the traditional domestic vacuum rake dryer, which is designed to strengthen and improve various slurry, paste, granular, powder, fiber and other materials. The transmission part adopts stable, Durable cylindrical gear reducer, the drive shaft adopts a thickened solid shaft, which fully guarantees the stable operation of the vacuum rake dryer in various harsh working environments; [0003] During the operation of the rake dryer, the temperature is high, and the axial movement during the reaction process is relatively large. The traditional double-end mechanical seal axial movement is controlled at 2mm, which cannot meet the conditions of on-site operation, especially in the In the case of high temperature and large...

Problems solved by technology

[0003] During the operation of the rake dryer, the temperature is high, and the axial movement during the reaction process is relatively large. The traditional double-end mechanical seal axial movement is controlled at 2mm, which cannot meet the conditions of on-site operation, especially in the In the case of high temperature and large axial movement, the traditional double-end mechanical seal will appear at the end of its service life. Therefore, the present invention proposes a large axial movement double-end mechanical seal device for rake dryers to solve the existing problems. problems in technology
