Description
Technical Field
The utility model belongs to the technical field of material conveying equipment and specifically relates to a powder sealing device for bucket elevator shaft.
Background
In the bucket elevator used at present, a bearing must be arranged outside a box body, a shaft must penetrate through the box body, and here, the sealing manufacturers always use simple packing for sealing, and the service life of the packing is extremely short. In the operation process, the chain drives the bucket to rotate and drives the gas flow in the process, particularly, the bottom of the bucket can form positive pressure, and most of bucket elevators can drop materials when unloading, so that the formation and overflow of dust at the bottom of the bucket elevator are aggravated. Under the positive pressure in the bucket elevator, the material leakage phenomenon frequently occurs in the conventional filler seal, once the material leakage is slight, the seal filler loses efficacy quickly, dust materials are sprayed out from the shaft seal, the working environment of the lower part of the bucket elevator is severe, the service life of a bearing and other parts is influenced by the powder feeding of the bearing in a high-dust environment, and the problem becomes more remarkable under the increasingly severe environment-friendly situation.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a stable, high-efficient, environmental protection be used for powder sealing device of bucket elevator axle.
The utility model adopts the following technical scheme:
a powder sealing device for a shaft of a bucket elevator comprises a packing sealing device, wherein the packing sealing device is sleeved on a rotating shaft of the bucket elevator and comprises a primary packing box and a secondary sealing ring, the primary packing box is fixed with a box body of the bucket elevator, a primary gland is arranged on one side of the primary packing box, which is far away from the box body, and primary packing is filled between the primary packing box and the primary gland; one side of the first-stage gland, which is far away from the first-stage packing box, is connected with a second-stage gland through a second-stage sealing ring, and second-stage packing is filled between the second-stage sealing ring and the second-stage gland; through lead screw connection between one-level gland and the second grade gland, lead screw and one-level gland fixed connection, with second grade sealing ring swing joint, the one end of keeping away from the second grade gland on the lead screw is provided with pressure spring.
Compared with the prior art, the beneficial effects of the utility model are that:
the utility model discloses just have red two-stage packing sealed form to compress tightly by the spring with lead screw connection, utilize the pretightning force of spring to compress tightly the filler constantly, can effectually prevent that the dust material is excessive, thoroughly solve the problem that bucket elevator axis of rotation department leaked the material, improved bucket elevator's work efficiency, reduced environmental pollution.
Further, the utility model discloses a preferred scheme is:
the lead screw is provided with two, and two lead screws set up about axis of rotation symmetry, and every lead screw is connected with the second grade gland through hold-down spring respectively, and hold-down spring's one end is fixed with the second grade gland, and the other end passes through the fastening nut of lead screw tip to be fixed.
The first-level packing and the second-level packing are respectively tetrafluoro packing.
A sealing gasket made of PTFE material is arranged between the first-stage stuffing box and the second-stage sealing ring.
