Has the following advantages: the problem of regulating spindle compress tightly the regulating plate and do not reciprocate is solved, the gap leakage problem appears too fast in the pinch plate and the eccentric shaft wearing and tearing has been solved again, drives antifriction bearing through rotatory eccentric shaft and adjusts the elasticity that the dull and stereotyped compressed tightly the wool felt and reach sealed effect.
Description
Technical Field
The utility model relates to an adjust eccentric shaft sealing device belongs to mechanical equipment technical field.
Background
In the production flow of powder lifting, a plate chain lifter is the most applied equipment at present, and the tail part of the lifter is sealed by adopting the following devices: the compressing degree between the wool felt and the box body is adjusted through the rotation of the eccentric shaft, so that the aim of sealing is fulfilled. However, the rotating wheel of the hoister is stressed to move up and down continuously, so that the eccentric shaft is abraded, the gap between the wool felt and the box body is influenced, and dust leakage is caused. The eccentric shaft compresses tightly and can not alleviate the vibrations of chain again, and the one month needs to overhaul the regulation under normal condition. Therefore, the market is in urgent need to improve the sealing device, and the sealing device which can achieve long sealing time and move up and down along with the rotating wheel is needed.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is not enough to the top, provides an adjust eccentric shaft sealing device, has solved the regulating spindle and has compressed tightly the regulating plate and not reciprocate the problem, has solved pressure strip and eccentric shaft wearing and tearing too fast the clearance leakage problem that appears again, drives antifriction bearing through rotatory eccentric shaft and adjusts the dull and stereotyped elasticity degree that compresses tightly the wool felt and reach sealed effect.
For solving the technical problem, the utility model discloses a following technical scheme:
the utility model provides an adjust eccentric shaft sealing device, includes the hoist box, sealing device main part and eccentric shaft, and the sealing device main part sets up the both sides at the hoist box, and the surface welded fastening of hoist box has the eccentric shaft fixed plate, and the eccentric shaft is installed on the eccentric shaft fixed plate.
Further, the eccentric shaft can rotate relative to the eccentric shaft fixing plate.
Furthermore, the eccentric shaft fixing plate can be fixedly locked on the eccentric shaft fixing plate through a locking nut.
Furthermore, a spring washer is arranged between the locking nut and the eccentric shaft fixing plate.
Furthermore, one end of the eccentric shaft penetrating through the eccentric shaft fixing plate is provided with a rolling bearing, the other end of the eccentric shaft is provided with a stud, and the stud and the rolling bearing have a certain eccentric distance. .
Furthermore, the rolling bearing is limited on the eccentric shaft through a clamp spring.
Furthermore, the sealing device main part includes wool felt, clamp plate and antifriction bearing, and wool felt and clamp plate are integrative to be removed along the short distance from top to bottom of lifting machine box.
Furthermore, the wool felt is located between the elevator box body and the pressing plate, the rolling bearing is located on one side, far away from the wool felt, of the pressing plate, and the rolling bearing is close to the pressing plate.
The utility model adopts the above technical scheme, compare with prior art, have following technological effect:
the pressure strip, the wool felt during operation reciprocates along with the swiveling wheel, adjusts the eccentric shaft motionless, only plays the compaction effect, and the removal of pressure strip and regulation eccentric shaft has become current rolling friction like this by original sliding friction. Therefore, the problem that the adjusting shaft compresses the adjusting plate not to move up and down is solved, and the problem of gap leakage caused by too fast abrasion of the compressing plate and the eccentric shaft is also solved.
