Abstract
The utility model belongs to the technical field of mechanical seal, and provides a big gear ring sealing device for a rotary kiln. The big gear ring sealing device for the rotary kiln is mainly characterized by improving an existing big gear ring sealing device for the rotary kiln and by comprising a big gear ring, a labyrinth sealing plate sleeved outside the big gear ring and big gear ring casting holes. A bridge is arranged on the big gear ring casting holes, and the bridge is fixedly connected with the labyrinth sealing plate sleeved outside the big gear ring and the big gear ring casting holes. The big gear ring sealing device for the rotary kiln can effectively avoid the oil leaking phenomenon of a rotary kiln riding wheel and has the advantages of being low in investment, simple in equipment, low in waste and the like.
Description
Technical field
The utility model belongs to the mechanical sealing technology field, relates to a kind of big gear ring of rotary kiln sealing device.
Background technology
Big gear ring of rotary kiln in use has a large amount of not oil of easy to clean to leak outside in operation process after the bad seals, severe contamination working environment, existing sealing device are repaired the cost height, and repair time is long, and is difficult for repairing.At present, have some rotary kilns to change oil jet lubrication into, but this effect is not good enough, still has oil leakage phenomenon in the use, this not only brings very large difficulty to environmental improvement, and one-time investment is also larger simultaneously, has increased the production cost of enterprise.
Summary of the invention
The inventor finds that in the daily course of work existing big gear ring of rotary kiln sealing exists defects, through design improvement, technical problem to be solved in the utility model provides a kind of small investment, equipment is manufactured simple big gear ring of rotary kiln sealing device.
For solving the problems of the technologies described above, technical solution adopted in the utility model is that designed big gear ring of rotary kiln sealing device comprises bull gear, bull gear outer cover labyrinth seal plate, bull gear casting hole, establish crane span structure at the bull gear casting hole, described crane span structure all is fixedly connected with bull gear outer cover labyrinth seal plate, bull gear casting hole.
Described crane span structure is 12, is evenly distributed on the bull gear.
The utility model adopts the designed big gear ring of rotary kiln sealing device of technique scheme, the crane span structure and the clamping device that utilize redesign to manufacture, sealing ring is connected together with bull gear securely, effectively prevented from coming off and the not oil leakage of easy to clean in equipment bull gear sealing in service, realized that lubricated oil is free from environmental pollution, minimizing is to environmental investment (comprising manpower, goods and materials), and this device has the advantages such as small investment, equipment manufacture technology be simple.
Description of drawings
Fig. 1 represents the structural representation of the utility model big gear ring of rotary kiln sealing device.
The specific embodiment
Specify below in conjunction with the structure of accompanying drawing to the utility model big gear ring of rotary kiln sealing device.
Referring to Fig. 1, the structure of the utility model big gear ring of rotary kiln sealing device comprises bull gear 4, bull gear outer cover labyrinth seal plate 1, bull gear casting hole 3, establish crane span structure 2 at bull gear casting hole 3, crane span structure 2 can be established 12 and also evenly be laid in respectively on the bull gear 4, crane span structure 2 is welded on the bull gear outer cover labyrinth seal plate 1, crane span structure 2 is connected and fixed by stud 5 with the bull gear casting hole, crane span structure 2 becomes one with original bull gear outer cover labyrinth seal plate 1, form together new sealing with bull gear shell labyrinth sealing body 6, thereby play sealing function.
The utility model is on probation through trial-production, facts have proved the generation that can effectively prevent the supporting roller of rotary kiln oil leakage phenomenon, has that small investment, equipment are simple, the advantage such as cut the waste.
