Abstract
The utility model relates to a sealing device of a screw conveyer. The sealing device comprises a screw shaft, a connecting shaft, shaft seal seats, covers, shaft seal seat end covers and sealing fillers, wherein the connecting shaft is arranged on the two sides of the screw shaft, the shaft seal seats are arranged on the connecting shaft, the glands and the shaft seal sat end covers are arranged on the two sides of the shaft seal seats, the shaft seal seats are tightly attached with the screw shaft, the sealing fillers are arranged between each shaft seal seat and the connecting shaft, lantern rings are arranged between the shaft seal seats and the shaft seal seat end covers; sealing rings are arranged in the lantern rings; oil cavities are formed by the sealing fillers and the sealing rings; and butter is filled in the oil cavities. According to the sealing device of the screw conveyer provided by the utility model, even if the work environment is filled with a large amount of dust, and after entering the shaft seal seats, the dust can be adhered by the butter and can not leak easily, so that the failure of the sealing fillers caused by the dust can not occur easily, the service life of the sealing fillers can be prolonged, the replacement period of the sealing filler is prolonged, and the production cost is lowered.
Description
Technical field
The utility model relates to a kind of screw conveyor, relates in particular to a kind of seal arrangement of screw conveyor.
Background technique
Screw conveyor is a kind of continuous conveyor that does not have the flexure member traction, utilizes the rotation conveying material of spiral.The seal arrangement of general screw conveyor shown in accompanying drawing 1, comprises screw axis 1, coupling shaft 2, axle envelope seat 3, gland 4, axle envelope seat end cap 5 and stuffing box packing 6; The both sides of screw axis 1 are provided with coupling shaft 2; The both sides of screw axis 1 are provided with coupling shaft 2, and coupling shaft 2 is provided with axle envelope seat 3, and the both sides of axle envelope seat 3 are provided with gland 4 and axle envelope seat end cap 5; Axle envelope seat end cap 5 is close to screw axis 1, and axle envelope seat 3 and 2 of coupling shafts are provided with stuffing box packing 6.But when screw conveyor is used to carry cement or carries the colliery; Because of the dust at scene is bigger, working environment is comparatively abominable, and dust gets in the axle envelope seat 3 extremely easily; Make stuffing box packing 6 lose efficacy; Reduced the working life of stuffing box packing 6, made stuffing box packing 6 frequent change, break-in has increased cost of production.
The model utility content
The utility model purpose is that a kind of seal arrangement that is difficult for the screw conveyor of inefficacy at the bigger working environment lower seal filler of dust is provided for the deficiency that overcomes existing technology.
For achieving the above object; The technological scheme that the utility model adopts is: a kind of seal arrangement of screw conveyor, comprise screw axis, coupling shaft, axle envelope seat, gland, axle envelope seat end cap and stuffing box packing, and the both sides of said screw axis are provided with coupling shaft; The both sides of said screw axis are provided with coupling shaft; Said coupling shaft is provided with axle envelope seat, and the both sides of said axle envelope seat are provided with gland and axle envelope seat end cap, and said axle envelope seat end cap is close to screw axis; Be provided with stuffing box packing between said axle envelope seat and coupling shaft, be provided with the collar between said axle envelope seat and axle envelope seat end cap; Be provided with seal ring in the said collar; Said stuffing box packing and seal ring form an oil pocket; In the said oil pocket butter is housed.
Preferably, the outside of said gland is provided with dust retaining ring.
Preferably, the said collar is provided with oil hole; Said oil hole communicates with oil pocket.
Preferably, said gland is fixing with axle envelope seat through bolt and nut.
Because the utilization of technique scheme, the utility model compared with prior art has advantage:
The seal arrangement of the screw conveyor of the utility model owing to be provided with the collar between axle envelope seat and axle envelope seat end cap, is provided with seal ring in the collar; Stuffing box packing and seal ring form an oil pocket, in the said oil pocket butter are housed, even in dust bigger following time of working environment; After dust got into axle envelope seat, meeting was adhered to by butter and is difficult for leaking, and makes dust be difficult for causing the inefficacy of stuffing box packing; Increase the working life of stuffing box packing, prolonged the replacement cycle of stuffing box packing, reduced cost of production; Because the outside of gland is provided with dust retaining ring, dust is difficult for getting into axle envelope seat, makes that stuffing box packing is difficult for losing efficacy, and has further increased the working life of stuffing box packing.
Description of drawings
Below in conjunction with accompanying drawing the utility model technological scheme is described further:
Accompanying drawing 1 is the structural representation of transmission device of the screw conveyor of existing technology;
Accompanying drawing 2 is the structural representation of transmission device of the screw conveyor of the utility model;
Wherein: 1, screw axis; 2, coupling shaft; 3, axle envelope seat; 4, gland; 5, axle envelope seat end cap; 6, stuffing box packing; 7, bolt; 8, nut; 9, dust retaining ring; 10, the collar; 11, seal ring; 12, oil pocket; 13, oil hole.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is done further to specify.
The seal arrangement of the described a kind of screw conveyor of the utility model shown in accompanying drawing 2; Comprise screw axis 1, coupling shaft 2, axle envelope seat 3, gland 4, axle envelope seat end cap 5 and stuffing box packing 6; The both sides of said screw axis 1 are provided with coupling shaft 2, and the both sides of said screw axis 1 are provided with coupling shaft 2, and said coupling shaft 2 is provided with axle envelope seat 3; The both sides of said axle envelope seat 3 are provided with gland 4 and axle envelope seat end cap 5, and said gland 5 is fixing with axle envelope seat 3 through bolt 7 nuts 8; The outside of said gland 5 is provided with dust retaining ring 9; Said axle envelope seat end cap 5 is close to screw axis 1, and said axle envelope seat 2 and 3 of coupling shafts are provided with stuffing box packing 6, and said axle envelope seat 2 and 5 of end caps of axle envelope seat are provided with the collar 10; Be provided with seal ring 11 in the said collar 10; Said stuffing box packing 6 forms an oil pocket 12 with seal ring 11; In the said oil pocket 12 butter is housed; The said collar 10 is provided with oil hole 13; Said oil hole 13 communicates with oil pocket 12.
During use, butter is injected in the oil pocket 12 through oil hole 13.After dust got into axle envelope seat 3, meeting was adhered to by butter and is difficult for leaking, and makes dust be difficult for causing the inefficacy of stuffing box packing 6, has increased the working life of stuffing box packing 6, has prolonged the replacement cycle of stuffing box packing, has reduced cost of production; Gland 5 outer dust retaining rings 9 can stop dust to get into axle envelope seat 3, make stuffing box packing 6 be difficult for losing efficacy, and have further increased the working life of stuffing box packing.
Below only be the concrete exemplary applications of the utility model, the protection domain of the utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technological scheme of formation, all drop within the utility model rights protection scope.
