Abstract
The utility model discloses a pressure screen shaft seal device. The pressure screen shaft seal device comprises a shaft sleeve, a labyrinth device, a labyrinth upper cover, a labyrinth base, a spring, a frame oil seal and a frame oil seal base, wherein the shaft sleeve is arranged on a pressure screen shaft through the labyrinth upper cover, the labyrinth device is arranged on the upper portion of the labyrinth base and the lower portion of a gasket, the labyrinth upper cover is fixedly arranged on an original mechanical seal base, the labyrinth base is arranged on an original mechanical seal base through the spring, and the frame oil seal is arranged inside the frame oil seal base. The whole pressure screen shaft seal device comprises the labyrinth device and the double-frame oil seal, the size of a gap between two seal surfaces is reduced, sealing performance is good, the probability of water leakage and slurry leakage of the whole pressure screen shaft seal device can be greatly reduced, the maintaining frequency of the pressure screen shaft seal device is reduced, and service life of the pressure screen shaft seal device is prolonged.
Description
Technical field
The utility model design papermaking equipment apparatus field, a kind of pressurized screen shaft sealer of specific design.
Background technology
Pressure screen(ing) machine is one of indispensable equipment at paper industry, and it can sieve plurality of impurities, as lumps, sicker, hot-melt object, chip etc.In workshop, pressurized screen secret envelope operating mode is comparatively severe, and the sealing device of current most pressure screen(ing) machines is comparatively simple, sealing effectiveness is not good, is not suitable with long-term production work, thereby sealing surface produces, gap easily causes leaking, spillage, maintenance of equipment is too fast, and cost cost is high.
Summary of the invention
The purpose of this utility model is to be to overcome above-mentioned the deficiencies in the prior art, and provide, a kind of good airproof performance, cost reduce greatly, pressurized screen shaft sealer simple in structure.
The utility model is achieved through the following technical solutions: it comprises axle sleeve, maze device, labyrinth upper cover, labyrinth seat, spring, outside framework oil seal and outside framework oil seal seat, described axle sleeve is installed on pressurized screen axle through labyrinth upper cover, described maze device is installed on seat top, labyrinth and pad bottom, described labyrinth upper cover is mounted on former mechanical sealing base, described labyrinth seat is through spring fitting on former mechanical seal piece, and described outside framework oil seal is installed in outside framework oil seal seat.
Described axle sleeve and axle are interference fit, can prevent that in the course of work, slurries overflow from axle top, and described spring fitting is between labyrinth seat and former mechanical seal piece, and the tension force of installation process medi-spring can play to labyrinth seat and maze device the effect of support.
Described outside framework oil seal is at least two, and described outside framework oil seal is mounted in outside framework oil seal seat through bottom jump ring; Two outside framework oil seal devices, have strengthened the sealing of pressurized screen shaft sealer, make to leak, spillage phenomenon greatly reduces.
Marked improvement of the present utility model and outstanding feature are:
1, single unit system comprises maze device and two outside framework oil seal, the gap of having reduced sealing surface, and good seal performance, thereby can greatly reduce, single unit system leaks, the probability of spillage, reduces the frequency of maintenance of equipment, adds the service life of large equipment.
2, single unit system is to improve on the basis of original sealing device, reduces the amount of labour, is suitable for fast.
