Description
Technical field
The utility model relates to a kind of sealing arrangement, is specifically related to a kind of conveyor screw axle end sealing device.
Background technology
The medium that conveyor screw is carried is a fine coal, and granularity is 200 orders, and pressure is 0.064Mp-0.073MP.The conveyor screw of prior art is to use the oil immersion packing_seal merely, though simple in structure, sealing effectiveness is poor, and fine coal leaks serious, and work-site has pollution, and bearing damages easily.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of conveyor screw axle end sealing device of good sealing effect.
It is as follows that the utility model solves the problems of the technologies described above the technical scheme of taking: a kind of conveyor screw axle end sealing device, comprise S. A., housing, end cap, gland cover and Sealing Device, it is characterized in that: Sealing Device comprises labyrinth seal ring, joint, O RunddichtringO and y-type seal ring; Labyrinth seal ring comprises labyrinth type rotating ring that is installed on the S. A. and the labyrinth type stationary ring that is arranged on the end cap, and labyrinth type rotating ring outer face and labyrinth type stationary ring inner end surface are provided with the concavo-convex labyrinth packing air channel of mutual concavo-convex fastening; End cap is provided with seal receptacle, is provided with air inlet duct between labyrinth type stationary ring outer face and the seal receptacle inner end surface; Joint is located on the end cap, and joint is provided with ventilation inlet, and air inlet duct is connected concavo-convex labyrinth packing air channel with ventilation inlet; The O RunddichtringO is installed between S. A. and the labyrinth type rotating ring; Y-type seal ring is contained between labyrinth type rotating ring and the seal receptacle.
Further, in the end cap cavity volume of labyrinth type rotating ring outer end ash damper is housed.
When the utility model uses, the ventilation inlet and the wind regime of joint are joined, by the external blowback pressure wind of ventilation inlet, blowback pressure is a little more than machine internal pressure 0.005MP, utilize labyrinth blowback form,, the pressure fine coal of internal body is sealed with the blowback pressure wind in conjunction with the rotary seal that is installed in the O RunddichtringO between S. A. and the labyrinth type rotating ring, the sealing of combined outside y-type seal ring, bearing front end increase an ash damper in case the fine coal that part is leaked enters in the bearing.The utility model is place in operation 2 years in production practice, does not have the fine coal leakage phenomenon through improved conveyor screw axle head, good sealing effect, thus thoroughly solved the difficult problem that fine coal leaks, guaranteed the normal operation of equipment.
Description of drawingsFig. 1 is a structural representation of the present utility model,
Fig. 2 is the conveyor screw sealing structure of shaft end scheme drawing of prior art.
Among the figure: 1-end cap, 101-seal receptacle, 2-labyrinth seal ring, 201-labyrinth type rotating ring, 202-labyrinth type stationary ring, 203-concavo-convex labyrinth packing air channel, 3-joint, 301-ventilation inlet, 4-air inlet duct, 5-y-type seal ring, 6-O RunddichtringO, 7-air baffle, 8-S. A., 9-gland cover, 10-housing, 11-pressure fine coal, 12-oil immersion packing.
As shown in Figure 1: a kind of conveyor screw axle end sealing device, comprise S. A. 8, housing 10, end cap 1, gland cover 9 and Sealing Device, Sealing Device comprises labyrinth seal ring 2, joint 3, O RunddichtringO 6 and y-type seal ring 5; Labyrinth seal ring 2 comprises labyrinth type rotating ring 201 that is installed on the S. A. 8 and the labyrinth type stationary ring 202 that is arranged on the end cap 1, and labyrinth type rotating ring 201 and labyrinth type stationary ring 202 inner end surfaces are provided with the concavo-convex labyrinth packing air channel 203 of mutual concavo-convex fastening; End cap 1 is provided with seal receptacle 101, is provided with air inlet duct 4 between labyrinth type stationary ring 202 outer faces and seal receptacle 101 inner end surfaces; Joint 3 is located on the end cap 1, and joint 3 is provided with ventilation inlet 301, and air inlet duct 4 is connected concavo-convex labyrinth packing air channel 203 with ventilation inlet 301; Article two, O RunddichtringO 6 is installed between S. A. 8 and the labyrinth type rotating ring 201; Y-type seal ring 5 is contained between labyrinth type rotating ring 201 and the seal receptacle 101.
Outer face is meant the end away from housing 10.As of the present utility model perfect,, in end cap 1 cavity volume of labyrinth type rotating ring 201 outer ends ash damper 7 is housed for further enhanced leaktightness effect.
Principle of work of the present utility model is roughly as follows: the blowback pressure wind enters labyrinth seal ring 2 through ventilation inlet 301, the air inlet duct 4 of joint 3, the pressure fine coal 11 that withstands in the housing 10 does not enter labyrinth seal ring 2, combined outside y-type seal ring 5, when S. A. 8 rotations, can in time compensate the slit that produces in the rotary course because y-type seal ring 5 is flexible, the blowback pressure wind sealed do not leak, reach good sealing effectiveness, thoroughly solved the difficult problem that fine coal leaks, guaranteed the normal operation of equipment.
