Problems solved by technology

[0003] At present, the forms and characteristics of the sealing device for rotary cylinder equipment are as follows: 1. Labyrinth sealing structure, which is only suitable for occasions with a small pressure difference from the atmosphere, and the sealing performance is poor; 2. Contact sealing Structural type, it is easy to move due to the axial and radial movement of the equipment, and the roundness of the cylinder will expand and lose circle due to temperature changes, which will lead to seal failure or even d

Embodiment 1

[0030] The flexible support assembly 1 is a support assembly of the same type evenly distributed along the circumference, which can play the role of connecting the rotating cylinder body and the moving ring assembly 3, and can offset the movement between the rotating cylinder body 13 and the moving ring assembly 3. Dynamic and thermal deformation; the above support components are made of leaf spring hinges and / or spring columns.

Embodiment 2

[0032] The ripple ring 2 is a special circular thin plate, and the inner and outer sides of the ripple ring 2 are respectively provided with connecting components, and the inner side of the ripple ring 2 is made into ripples; the ripple ring 2 is manufactured by integral stamping and / or welded Z-shaped plates.

Embodiment 3

[0034] The threaded holes on the moving ring assembly 3 are evenly distributed on the circumference, and the spring column assembly 5 installed in the threaded holes of the moving ring assembly 3 can automatically compensate the wear amount of the sealing block 6, and the front static ring 7 and the seal are connected by the set screw 4. The pressing force between blocks 6 is adjusted; the moving ring assembly 3 is provided with a grease lubrication injection channel, which can inject high temperature resistant grease through the external interface, which not only enhances its sealing performance, but also effectively reduces rolling resistance. The axial end surface of the sealing block 6 ensures that it has a small roughness, so that the sealing block 6 and the end surface of the front stationary ring 7 maintain a stable and uniform end surface contact seal; the radial cylindrical surface of the sealing block 6 is provided with O-ring grooves , and a special O-ring is install...

Abstract

The invention discloses a sealing device of rotating cylinder equipment. The sealing device of the rotating cylinder equipment comprises a flexible bearing assembly and spring column assemblies. The flexible bearing assembly is installed on a rotating cylinder body in a clearance fit manner. The flexible bearing assembly is fixed to a rotating seal ring assembly through bolts and/or hinges, the rotating seal ring assembly is fixedly provided with a ripple ring through bolts, the inner side of the ripple ring is tightly attached to the rotating cylinder body, threaded holes in an outer ring ofthe rotating seal ring assembly are provided with the spring column assemblies through set screws. A sealing block is arranged between one side of each spring column assembly and the rotating seal ring assembly in a sleeving manner. The outer side of the sealing block is provided with a front stationary seal ring, the front stationary seal ring is tightly attached to the sealing block to form a mechanical end face seal, and the front stationary seal ring is installed in an embedding groove of a rear stationary seal ring assembly. The sealing device has the beneficial effects that the error deformation generated in the rotating cylinder equipment production and manufacture process can be effectively offset, thermal deformation, axial bouncing and radial bouncing generated in the running process are resisted, the tight attaching and coaxiality of the mechanical seal end face are guaranteed, and stable mechanical end face seal is maintained.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a rotary cylinder equipment sealing device. Background technique [0002] Rotary cylinder equipment is mainly used for material cooling, drying, reaction and other operations, and is widely used in chemical industry, building materials, metallurgy and other industries. In some special processes, the rotary cylinder equipment needs to isolate the air or prevent the leakage of harmful and toxic gases. The sealing performance of the rotary cylinder equipment is the key control point of the rotary kiln process. The leakage of the rotary kiln medium will affect the process indicators and even cause safety. ACCIDENT. On the rotary cylinder equipment, the cylinder body itself is rotating, while the kiln cover at the feeding or discharging end is stationary, which requires the sealing between the moving and static components. [0003] At present, the forms and characteristics of the s...
