Abstract
A sealing device for a mineral dressing classifier comprises a front round nut (1), a flange plate (2), a bearing (14), a gland II (16), a shock insulator (17), a bearing block (18), a shaft sleeve (19) and a shaft (21). The sealing device is characterized in that one end of the outer side of the shaft sleeve (19) close to the flange plate (2) is fixedly connected with a gland I (3) through an oil seal (6), the outer side of the gland I (3) is fixedly connected with an oil seal gland (7), the outer side of the oil seal gland (7) is connected with an oil seal sleeve (9), and the oil seal sleeve (9) and the shaft sleeve (19) are movably connected with each other through a compression spring (10), a pressing ring (11) and an oil seal combination (13). Therefore, the sealing device is simple in structure, fine in sealing effect, reliable in support and particularly applicable to mineral dressing equipment, and the effective service life of the lower bearing block can be prolonged by more than half a year.
Description
Technical field:
The utility model relates to a kind of sealing device, particularly a kind of ore dressing grader sealing device.
Background technology:
Spiral classifier is one of the capital equipment in ore dressing plant; Normal and ore mill constitutes closed circuit; Sand return big because of spiral classifier sand return hoisting depth, that promote with the granularity of control ore milling product continuously, stable, and the overflow of spiral classifier is stable, can obtain thinner ore pulp overflow; Improving grinding efficiency, is classifying equipoment generally commonly used.
The lower shaft bearing of spiral classifier helical axis is submerged in the ore pulp for a long time works, and operating condition is very abominable, and traditional lower supporting structure mode has: bearing block; Pressure water seal rubber bush axle bed, multiple modes such as pressure water seal resin shaft lining axle bed, its bottom bracket is used more; Spiral classifier also all adopts the bearing block form, and axle and bearing that hollow shaft drives in the bearing block are made low speed rotation, and the bearing block fixed axis is motionless; Bearing block play supporting role, and the seal of bearing is merely 1-2 month service life because the lower shaft bearing is submerged in the ore pulp for a long time and works; Its main cause of bearing block short life is that former bearing block adopts the asbestos packing packing seal because ore pulp and water cause due to the bearing wear after getting into, exist use a period of time after; Packing seal produces wearing clearance, causes ore pulp to be invaded, and makes axle, damage of bearings.
It sank lower bearing support in the pulp lower end of the screw shaft, to prevent the intrusion of pulp and water, twice the original use of mechanical packing labyrinth seal, since the lower bearing sinking pulp and long-term work, the filler gradually wear, will form a certain gap, the gap along the pulp and water immersion, of the lower bearing seat within the Di completely immersed in the pulp, causing the bearing easily damaged resulting in a lower bearing seat does not work, therefore, some of the lower seat bearing mill Average May require maintenance once two months have to be replaced once, increasing the labor intensity, but also affected the production, and some therefore scrapped, the mill had to stop all production and removal is very difficult to choose a certain amount of replacement parts plant Direct and indirect economic losses cut economic losses.
Summary of the invention:
The purpose of the utility model just provides a kind of simple in structure, good sealing effect, and supporting is reliable, can significantly increase lower shaft bearing Acceptable life above ore dressing grader sealing device half a year.
The purpose of the utility model is achieved in that a kind of ore dressing grader sealing device; Form by preceding round nut, ring flange, bearing, gland II, dottle pin, bearing block, axle sleeve, axle; It is characterized in that the described axle sleeve outside is fixedly connected gland I near an end of ring flange through oil sealing; The gland I outside is fixedly connected with oil sealing cover, the outside connection oil-sealing sleeve of oil sealing cover, and trim ring, oil sealing combined moving are connected outside the spring through compressing between oil-sealing sleeve and axle sleeve.
An optimum implementation of the utility model is:
Gland I is connected with elastic mounting through bolt I with oil sealing cover; Oil sealing cover is fixedly connected with bolt II through preceding offset plate with oil-sealing sleeve; Compression spring one end is fixedly connected on the sealing gland, and the other end connects the oil sealing combination through trim ring, and the oil sealing combination other end is connected with oil-sealing sleeve.
The utility model compared with prior art has the following advantages:
Owing to adopt the axle sleeve outside to be fixedly connected gland I through oil sealing near an end of ring flange; The gland I outside is fixedly connected with oil sealing cover, the outside connection oil-sealing sleeve of oil sealing cover, between oil-sealing sleeve and axle sleeve through compressing the type of attachment that trim ring, oil sealing combined moving are connected outside the spring; Thereby it is simple in structure; Good sealing effect, supporting is reliable, can significantly increase lower shaft bearing Acceptable life more than half a year.
