Description
Technical field
The utility model relates to the palletizing shaft furnace technical field, particularly relates to a kind of shaft furnace discaling roll sealing device, can solve shaft furnace discaling roll static and dynamic sealing problem effectively.
Background technology
Shaft furnace discaling roll sealing device divides and can be divided into by sealed nature: simple drier oil sealing and drier oil and filler mix sealing.At present, most of discaling rolls adopt simple drier oil sealing system, and the shortcoming of such sealing system is, sealing effectiveness is poor, and service life is short, and the greasy filth wearing and tearing discaling roll surface of generation is serious.Simultaneously, part adopts the labyrinth sealing system, and this kind seal structure complex is higher to the workpiece processing request, and in discaling roll end and furnace wall gap location buildup, easily under the furnace pressure effect, enters in the labyrinth, stops up oil circuit, can't better play sealing function.The patent No. is 01263243 shaft furnace discaling roll sealing system, be made up of discaling roll axle, shaft furnace shell, stuffing box, filler, gland, dividing plate, spacer ring etc., stuffing box has oilhole, the radial and axial oil seepage hole that all has of spacer ring, by to stuffing box water flowing cooling, reduce the temperature of packing seal place.This system is serious to the discaling roll surface abrasion, and it is serious to leak dirt, influences the service life of discaling roll.The patent No. is 200420068258.7 shaft furnace discaling roll sealing system, it comprise be in sealing ring that labyrinth sealing cooperates and rotating ring and between interior ring, sealing ring and spike roll discharger body connect firmly, be provided with asbestos packing between sealing ring and the rotating ring, be sleeved on that engage sleeves is equipped with sealing ring between rotating ring on the discaling roll and end cap and the discaling roll, connect firmly by bolt between rotating ring and the end cap, be fixedly connected with the sealing ring that is sealed and matched with it in the outer end of sealing ring, sealing ring is provided with 2 road asbestos packings, asbestos packing is provided with bolt hole, and bolt is installed in the bolt hole.This system architecture complexity easily produces in the labyrinth problems such as oil circuit obstruction, and bearing place lubricant effect is poor simultaneously, and bearing is short service life.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of shaft furnace discaling roll sealing device, and the sealing device is by adopting compressed air and drier oil that discaling roll is carried out hybrid sealing, having realized the sealing problem of discaling roll better.The technical scheme that the utility model adopted is as follows: this shaft furnace discaling roll sealing device is provided with a sealing axle sleeve, and sealing axle sleeve is provided with drier oil hand-hole, compressed air hand-hole.The sidewall of sealing axle sleeve is provided with fixing threaded hole, and sealing axle sleeve can be fixed on the shaft furnace body of heater by fixing threaded hole by bolt.And shaft furnace body of heater fixing threaded hole, sealing axle sleeve can be by being bolted on the shaft furnace body of heater.Described drier oil hand-hole is positioned at the compressed air hand-hole outside with respect to the vertical furnace body, and described drier oil hand-hole is axially vertical with sealing axle sleeve, and described compressed air hand-hole is axially angled with respect to sealing axle sleeve.The end of said sealing axle sleeve is provided with end cap, and end cap is provided with the end cap screw, and end cap is connected and fixed on the sealing axle sleeve end by bolt, and forms the packing case with sealing axle sleeve.In addition, cooperate with sealing axle sleeve to be provided with a bearing block, bearing seat is in the discaling roll outer end, and the transmission of discaling roll system is played a supportive role.
The utility model good sealing effect, by drier oil and compressed-air actuated immixture, can in sealing axle sleeve, form the high-tension lubrication chamber, with the hyperbaric environment formation convection current in the vertical furnace, stop leaking outside of high pressure draught and mineral aggregate effectively, guaranteed the static and dynamic sealing problem in the discaling roll running.Reduce the temperature of discaling roll surface and grease simultaneously, improved service life; Be easy to dismounting, the existing discaling roll sealing system of this system, installed part is few, and simple in structure, and in the installation process, the spare part required precision is relatively low, more helps removing and installing in the maintenance process; Long service life; The discaling roll surface of not wearing and tearing because inboard compressed air can stop leaking outside of mineral aggregate effectively, can form lubricating oil film preferably between sealing axle sleeve and discaling roll axle, the minimizing running wear phenomenon; Simple in structure, cheap.
