Sealing device of rotating cylinder equipment

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...

AI Technical Summary

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 damage; 3. The composite sealing structure is more suitable for applications where the sealing requirements are compared In strict rotary kiln operation occasions; 4. The gas-sealed sealing structure realizes that the medium in the kiln does not leak out through the pressure difference

[0004] Therefore, in order to overcome the problem that the sealing structure of the existing rotary cylinder equipment is prone to failure and leakage, a rotary cylinder equipment sealing device with better sealing effect is provided
