Abstract
The invention discloses a wear-resistance flotation machine rotor device, which comprises a cover plate and blades, wherein the cover plate is in a round shape, a through hole is formed in the center of the cover plate, a filter cover is assembled on the through hole, one end surface of the blades is fixedly connected with a connecting plate, the blades are fixedly arranged on the cover plate through the connecting plate, the connecting plate is connected with the cover plate through a hexagon socket screw, the blades are uniformly and straightly ranged in the circumference direction of the cover plate, and a wear-resistance lining plate is arranged on the side of the blades in the direction facing the flowing direction of ore pulp. The lining plate is made of wear-resistance and acid-resistance alloy materials, the lining plate is also fixed on the blades through screw bolts, the connecting plate of the blades prevents the abrasion caused by material pulp on the base, and the abrasion speed of the ore pulp on the blades is reduced by the lining plate, so the service life of a stator is longer. In the maintenance process, the separation of the blades from the cover plate can be realized only through dismounting the fastening screw bolts, the replacement of the blades is simple, the implementation is easy, only a new lining plate needs to be replaced when only the blade lining plate is abraded, the service cycle is long, and the maintenance work load is small.
Description
Technical field
The present invention relates to benficiation machinery, relating in particular to is a kind of wear-resisting rotors for flotation device.
Background technology
Flotation device is benficiation machinery commonly used on mining processing industry, isolate the mineralogical composition of needs for floatation process from the ore pulp that contains mineral, and objectionable impurities content in the reduction mineral, flotation device is comprised of central tube, main shaft, cell body, rotor, stator etc., rotors for flotation is rotated in pulp tank or flotation cell, stir ore pulp and the air dispersion of ore pulp is formed to bubble, in ore pulp, need the composition separated adsorbed by foam and float to the ore pulp surface, along with removing of foam realized flotation.
In the prior art, rotors for flotation is made of one formation type usually, and several fixed blades are arranged on rotor block, and blade stretches out with circumferentially becoming certain inclination angle with respect to rotor center, and axially by the cover plate position, to rotor tip, is being shunk gradually.Flotation device is in service, the rotor blade outside that organic engineering material processes and blade are connected root position and easily wear and tear because of the ore pulp erosion with cover plate, the rotor quick abrasion life-span is short, maintenance is frequent, and being limited to operating space and equipment working condition, the part exposed at epitrochanterian connecting bolt also easily is subject to the ore pulp erosion and causes the dismounting difficulty simultaneously.
Summary of the invention
For the deficiencies in the prior art part, the present invention aims to provide a kind of wear-resisting rotors for flotation device, guarantees to improve the rotor wearability, easy maintenance operation.
The technical solution used in the present invention: a kind of wear-resisting rotors for flotation device, comprise cover plate and blade, cover plate is rounded, be through hole in the cover plate centre, be equipped with filtering cover on through hole, at an end face of blade, be fixed with gusset piece, it is fixing on the cover board that blade pass is crossed gusset piece, gusset piece connects with hexagon socket head cap screw with cover plate, and blade is along circumferential evenly upright arrangement of cover plate, in the flow of slurry of meeting of blade, to face, is provided with abrasion-proof backing block.
Cover plate and blade adopt the organic engineering material material of light high tenacity, the machine-shaping of individual blade independence, blade and gusset piece form integral body, be trapezoidal at vertical section, the gusset piece of blade also is processed with bolt hole, blade is joined Kong Houyong with base and is connected with hexagon socket head cap screw, several piece blade circumferential array is embedded on base in ring-type, liner plate is made by wear-resisting acidproof alloy material, liner plate also is secured by bolts on blade, the gusset piece of blade has prevented the wearing and tearing of slip to base like this, liner plate reduces the rate of wear of ore pulp to blade, make the stator longer service life, safeguard simpler.In maintenance process, only need to remove fastening bolt and just can realize that blade separates with cover plate, blade exchanging is simple, if be only that the blade wear liner only need more renew liner plate, thereby the long maintenance load of life cycle is few.
Rotor is split into to several individual vanes, the little lightweight easy-formation of individual blade volume.
The present invention can directly change abrasion-proof backing block, and maintenance more easily operates than prior art, and maintenance cost is low.
The accompanying drawing explanation
Accompanying drawing 1 structural representation of the present invention;
In accompanying drawing: 1 cover plate 2 blade 3 gusset piece 4 liner plate 5 filtering cover 6 hexagon socket head cap screws.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described:
As Fig. 1, shown in Fig. 2, a kind of wear-resisting rotors for flotation device, comprise cover plate 1 and blade 2, cover plate 1 is rounded, in cover plate 1 centre, it is through hole, be equipped with filtering cover 5 on through hole, also be provided with airstrainer in filtering cover 5, an end face at blade 2 is fixed with gusset piece 3, blade 2 forms an integral body with gusset piece 3, actually add man-hour, blade 2 is easily made by casting mould with gusset piece 3, blade 2 is fixed on cover plate 1 by gusset piece 3, processing bolt hole on gusset piece 3 and cover plate 1, gusset piece 3 is connected into one with cover plate 1 by hexagon socket head cap screw 6, hexagon socket head cap screw 6 chieftains sink in cover plate 1, can prevent that ore pulp from causing the dismounting difficulty to the wearing and tearing of bolt head, blade 2 is along circumferentially evenly upright arrangement of cover plate 1, on cover plate 1, edge circumferentially arranges polylith blade 2, blade 2 one ends are near cover plate 1 centre, blade 2 other ends are near cover plate 1 outer ledge, the flow of slurry of meeting at blade 2 is provided with abrasion-proof backing block 4 to face, liner plate 4 global shapes are similar to blade 2, liner plate 4 is made for wear-resisting acid resisting material, liner plate 4 is connected into one by bolt and blade 2, change liner plate 4 while overhauling so simple, the use of liner plate 4 makes rotor long friction durability.
