Description

Permanent magnet roller bearing sealing device

Technical Field

The utility model belongs to the technical field of permanent magnetism cylinder ore dressing equipment, concretely relates to permanent magnetism cylinder bearing sealing device.

Background

The permanent magnet roller is an important link for the development of mineral processing equipment, has stable and excellent separation indexes, high processing capacity, simple operation and convenient management, and can simplify the process flow configuration, so the permanent magnet roller is widely applied. At present, a conventional permanent magnet roller end bearing comprises a bearing gland and a framework oil seal embedded in the bearing gland, wherein the bearing gland is close to a bearing, the framework oil seal can be failed in a short period by ore pulp entering from a gap between the gland and a shaft neck, the working surface of the bearing is further corroded, the bearing is prematurely failed, and the ore pulp entering a bearing box can aggravate the abrasion to the bearing box and a roller main shaft. The worn bearing box and the roller main shaft lose the effect of isolating ore pulp from entering the barrel, the ore pulp is adsorbed on the surface of the magnetic system by magnetic force once entering the barrel, the movement gap between the magnetic system and the barrel is blocked, the fixed steel belt of the permanent magnet block group in the barrel is worn, and the magnetic block group is disassembled, so that the whole permanent magnet roller is scrapped. Therefore, after the permanent magnet roller is normally used for 2-3 months, the permanent magnet roller must be disassembled, maintained and replaced to lose parts or replace the whole machine, and as the mineral processing system is in a 24-hour uninterrupted operation production mode, a fault occurs, namely, the capacity of the sorting system is insufficient or the function fails, so that the normal production and the product quality are seriously influenced.

Disclosure of Invention

The utility model aims at overcoming the not enough of prior art, provide a permanent magnetism roller bearing sealing device.

The purpose of the utility model is realized by the following technical scheme:

the utility model discloses a permanent magnetism cylinder bearing sealing device, including the cylinder main shaft, the permanent magnetism cylinder, the cover is established at the epaxial cylinder bearing of cylinder, and the cover is established at the skeleton oil blanket in the cylinder bearing outside and is set up the skeleton oil blanket with the bearing gland in the cylinder bearing outside, bearing gland passes through the bolt and the tip fixed connection of permanent magnetism cylinder, its characterized in that: also comprises a water retaining ring and an annular water throwing plate,

the fixed cover dress of manger plate ring on left side cylinder main shaft, and the medial surface of manger plate ring and bearing gland's outside fixed connection, annular water-throwing plate be flexible annular water-throwing plate, be bucket shape structure, also the suit is on left side cylinder main shaft, with cylinder main shaft interference fit, and arrange the outside of manger plate ring in.

Further, the flexible annular water throwing plate is made of rubber materials.

Further, the outer diameter of the flexible annular water throwing plate is larger than that of the water retaining ring.

Furthermore, the outer end face of the bearing gland is processed into a plane, and the inner side face of the water retaining ring is connected with the outer side of the bearing gland through sealant.

The utility model has the advantages that:

part of slurry is thrown out through an annular water throwing plate arranged at the outermost side of the bearing gland; meanwhile, the arrangement of the water retaining ring can also reduce the inward permeation of slurry from the outside of the bearing cover, so that the service life of the bearing cover is prolonged exponentially, the maintenance frequency of the permanent magnet roller is reduced, and the maintenance cost of enterprises is saved.

Drawings

Fig. 1 is a schematic structural view of the sealing device for a permanent magnet roller bearing according to the present invention.

Detailed Description

The following further describes the embodiments of the present invention with reference to the drawings.

As shown in fig. 1, the utility model discloses a permanent magnet drum bearing sealing device, including drum main shaft 4, permanent magnet drum 1, the cover is established at drum main shaft 4's rolling bearing 2, and the cover is established at the skeleton oil blanket 3 in the 2 outsides of rolling bearing and is set up skeleton oil blanket 3 with the bearing cover 7 in the 2 outsides of rolling bearing, bearing cover 7 passes through the bolt and permanent magnet drum 1's tip fixed connection, its characterized in that: still include breakwater 6 and annular water slinger 5, breakwater 6 fixed suit on left side cylinder main shaft 4, and the medial surface of breakwater 6 and bearing cover 7's outside fixed connection, annular water slinger 5 be flexible annular water slinger, be the bucket-shaped structure, also the suit is on left side cylinder main shaft 4, with 4 interference fit of cylinder main shaft, and arrange the outside of breakwater 6 in. The utility model can throw partial mud out through the annular water baffle 5 arranged at the outermost side of the bearing gland 7; meanwhile, the arrangement of the water retaining ring 6 can also reduce the inward permeation of slurry from the outside of the bearing cover 7, so that the maintenance frequency of the permanent magnet roller 1 is reduced, and the maintenance cost of enterprises is saved.

Further, the outer diameter of the flexible annular water throwing plate is larger than that of the water retaining ring, the inner side of the flexible annular water throwing plate is attached to the outer edge of the water retaining ring 6 in an inclined angle mode, and the flexible annular water throwing plate is an annular water throwing plate 5 made of rubber materials. By adopting the structure, the penetration of slurry from the flexible annular water slinger to the water retaining ring 6 can be reduced, and the sealing effect of the bearing gland 7 is further improved.

Furthermore, the inner side surface of the water retaining ring 6 is connected with the outer side of the bearing gland 7 through a sealant, and the outer diameter of the water retaining ring 6 is smaller than or equal to that of the bearing gland 7; when the water retaining ring 6 needs to be replaced or the roller bearing 2 needs to be maintained, the connection mode of the sealant can enable the water retaining ring 6 to be more convenient to detach.

Further, the outer end face of the bearing gland 7 is processed into a plane, so that the outer end face of the bearing gland 7 is better combined with the water retaining ring 6, and the infiltration of slurry is reduced; meanwhile, a raised sealing strip is formed by sealant at the outer edge of the contact surface of the water retaining ring 6 and the bearing gland 7 so as to enhance the sealing effect.

The utility model discloses a working process:

the retaining collar 6 and the annular water deflector 5 that fix the cover dress on cylinder main shaft 4 and set gradually in the outside of bearing gland 7 rotate with cylinder main shaft 4 synchronous when permanent magnetism cylinder during operation to throw away partial mud through annular water deflector 5, simultaneously, annular water deflector 5 becomes inclination laminating and water deflector 6's outward flange and the setting of water deflector 6 also can prevent mud from the inside infiltration of bearing gland 7 outside.
