Abstract

The invention discloses a seal device. The seal device comprises a seal sleeve, a concave seal sleeve, a convex seal sleeve, a seal spring and a compacting sleeve, wherein the seal sleeve, the concave seal sleeve, the convex seal sleeve and the compacting sleeve are sequentially sleeved on a rotor shaft, the seal spring is arranged between the convex seal sleeve and the compacting sleeve, and connection surfaces of the concave seal sleeve and the convex seal sleeve are matched through a maze-shaped structure. The seal device disclosed by the invention has the characteristics of good seal effect, simple structure and convenience for maintenance by utilizing the maze-shaped seal structure.

Description

technical field [0001] The invention relates to the field of rubber production equipment, in particular to a sealing device for the rotor of a rubber kneader. Background technique [0002] There are many deficiencies in the work of rubber and plastic kneaders, especially the problem of rotor end face sealing. The existing kneader rotor sealing device adopts axial end face seal, but its structure is complicated, maintenance is troublesome, and the sealing effect is poor. Contents of the invention [0003] The object of the present invention is to overcome the above disadvantages and provide a sealing device. [0004] The technical solution adopted by the present invention to achieve the above purpose is: a sealing device, including a sealing sleeve, a sealing concave sleeve, a sealing convex sleeve, a sealing spring, and a compression sleeve. The sealing sleeve, sealing concave sleeve, sealing convex sleeve, The compression sleeve is sequentially set on the rotor shaft...
