Abstract
The utility model discloses a modified flotation machine rotor device which comprises a cover plate and blades. The cover plate is round, through holes are formed in the center of the cover plate, a filter cover is arranged on the through holes, a connecting plate is fixed on one end face of each blade, the blades are fixed on the cover plate through the connecting plates, the connecting plates are connected with the cover plate through inside hexagonal bolts, the blades are evenly and vertically arranged in the circumference direction of the cover plate, and wear-resisting lining plates are arranged on the faces, facing towards ore pulp, of the blades. The lining plates are made of wear-resisting and acid-proof alloy materials, the lining plates are fixed on the blades through bolts, the connecting plates of the blades prevent pulp from abrading a base, the lining plates lower abrasion speed of blades by ore pulp, the service life of a stator is prolonged, and in the maintenance process, the fastening bolts just need to be dismounted to separate the blades and the cover plate, and the blades are simple in replacement; if only the lining plates of the blades are abraded, the lining plates are replaced by new lining plates, the service cycle is long, and repairing workload is little.
Description
Technical field
The utility model relates to benficiation machinery, and relating in particular to is a kind of improved rotors for flotation device.
Background technology
Flotation device is benficiation machinery conventional on mining processing industry, for floatation process, from the ore pulp that contains mineral, isolate the mineralogical composition of needs, and reduce objectionable impurities content in 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 separated composition to be adsorbed by foam and float to ore pulp surface, along with removing of foam realized flotation.
In the prior art, rotors for flotation is made of one formation type conventionally, has several fixed blades on rotor block, and blade stretches out with circumferentially becoming certain inclination angle with respect to rotor center, and axially by cover plate position, to rotor tip, is being shunk gradually.Flotation device is in service, rotor blade outside and blade that organic engineering material processes are connected root position easily because ore pulp erosion is worn and torn 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 exposing at epitrochanterian connecting bolt is also easily subject to ore pulp erosion and causes dismounting difficulty simultaneously.
Summary of the invention
For the deficiencies in the prior art part, the utility model aims to provide a kind of improved rotors for flotation device, guarantees to improve rotor wearability, easy maintenance operation.
The technical solution adopted in the utility model: a kind of improved rotors for flotation device, comprise cover plate and blade, cover plate is rounded, in cover plate centre, be through hole, on through hole, be equipped with filtering cover, 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, at vertical section, be trapezoidal, the gusset piece of blade is also 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 is also 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 stator longer service life, safeguard simpler.In maintenance process, only need dismounting fastening bolt just can realize blade separated with cover plate, blade exchanging is simple, if be only that blade wear liner only need more renew liner plate, thereby the long maintenance load of life cycle is few.
Rotor is split into several individual vanes, the little lightweight easy-formation of individual blade volume.
The utility model can directly be changed abrasion-proof backing block, and maintenance more easily operates than prior art, and maintenance cost is low.
Accompanying drawing explanation
Accompanying drawing 1 the utility model structural representation;
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 utility model is further described:
As Fig. 1, shown in Fig. 2, a kind of improved 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, on through hole, be equipped with filtering cover 5, in filtering cover 5, be also provided with airstrainer, an end face at blade 2 is fixed with gusset piece 3, blade 2 is in aggregates with gusset piece 3 shapes, 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 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 end 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, while overhauling like this, change liner plate 4 simple, the use of liner plate 4 makes rotor long friction durability.
