The sealing device comprises a main shaft for mounting of the rotary drum and driving the rotary drum to rotate, wherein the main shaft is sleeved with a bearing; one side, which is located on the bearing, of the main shaft is sleeved with a framework oil seal; bearing end covers are arranged on the outer sides, which are located on the framework oil seal and the bearing, of the main shaft; the bearing end covers are fixedly connected with the rotary drum; cover plates are fixedly mounted on the outer sides of the bearing end covers; a plurality of pieces of waterproof packing are arranged among the end parts of the cover plates and the main shaft; and lubricating grease is filled between the waterproof packing and the framework oil seal. The sealing device has the characteristics that the design is reasonable, the structure is simple and compact, the performance is stable and reliable, the service life is long, the application range is wide, the detachment is simple, the maintenance is convenient, the production process is simple and the production cost is low; and the sealing device is convenient to popularize and use.
Description
Technical field
The utility model belongs to mine equipment technical field, relates to a kind of sealing device, is specifically related to a kind of drum magnetic separator cylinder end seal.
Background technology
At present, conventional magnetic separator end bearing is by the rubber framework grease seal and the grease composition that are embedded in bearing gland, and bearing gland distance between bearing is nearer, and the ore pulp entering from gland and axle journal gap will make outside framework oil seal inefficacy in a short time, and then the working face of erosion bearing, cause bearing premature failure.If this fault can not be got rid of in time, the ore pulp entering in bearing housing will aggravate the grinding to bearing housing, main shaft.Bearing housing after wearing and tearing, main shaft have lost the effect that isolation ore pulp enters cylindrical shell, once it is just surperficial in magnetic system by magnetic-adsorption that ore pulp enters cylindrical shell, the movement clearance by stopping up between magnetic system and cylindrical shell, cannot rotate cylindrical shell, when serious, magnetic system departs from jaw completely, thereby whole magnetic separator is scrapped.Therefore, magnetic separator uses after 2～3 months normal, must check also more oil change and outside framework oil seal, because ore-sorting system is 24 hours uninterrupted running production models, breaks down and causes system to stop production completely, has a strong impact on normal production
Utility model content
The purpose of this utility model is to overcome above-mentioned deficiency of the prior art, a kind of drum magnetic separator cylinder end seal is provided, and it is reasonable in design, simple and compact for structure, stable and reliable for performance, long service life, applied widely, dismounting is simple, be convenient to safeguard, production technology is simple, and production cost is low, is convenient to promote the use of.
For achieving the above object, the technical solution adopted in the utility model is: a kind of drum magnetic separator cylinder end seal, comprise for mounting rotary drum and drive the main shaft of its rotation, on described main shaft, be arranged with bearing, it is characterized in that: on described main shaft, be positioned at described bearing one side and be arranged with outside framework oil seal, on described main shaft, be positioned at described outside framework oil seal and described bearing arranged outside has bearing (ball) cover, described bearing (ball) cover is fixedly connected with described cylinder, described bearing (ball) cover outside is installed with cover plate, between described patch ends and described main shaft, be provided with a plurality of waterproof packings, between described waterproof packing and described outside framework oil seal, be filled with lubricating grease.
Above-mentioned drum magnetic separator cylinder end seal, is characterized in that: described waterproof packing is two.
