Description
Technical field
The utility model relates to a kind of aluminium ash device for removing slag utilizing lever principle.
Background technology
In aluminum electrolysis aluminium ingot technology, the high temperature aluminum liquid of melting delivers to foundry by vaccum bench contracted affreightment, utilize natural gas holding furnace to prepare burden and reach certain chemical composition, because being mixed with a small amount of electrolyte in electrolysis primary aluminum, these electrolyte densities are less than raw aluminum liquid temperature, there is small part high temperature aluminum liquid to contact with the oxygen in air simultaneously, not too fine and close aluminium oxide can be generated, its density is also less than high temperature aluminum liquid temp, these are suspended in electrolyte and the aluminium oxide on high temperature primary aluminum top, workshop is referred to as aluminium ash, need before production to claw from high temperature primary aluminum, this technique is skimmed exactly.
In prior art, need several worker together directly to skim with large rake, one is that labour intensity is large; Two is easily cause high temperature primary aluminum to scald worker; Three is have the cleaning of place, part dead angle not thorough, easily causes slag inclusion impurity in aluminium ingot, causes mass defect; Four is that dead angle lime-ash cleaning adopts artificial rake (see Fig. 1), and because furnace temperature is high, skimmer one puts in holding furnace, and rake bar is distortion just, can not operate very well; Five be mechanical composite skip owing to affecting by fire door above, position, dead angle cannot be reached, cause the lime-ash of position, dead angle cumulative, in stove during the aluminium slag cleaning of deposition, holding furnace inner lining material can be damaged.
Summary of the invention
In order to overcome the shortcoming of above-mentioned prior art, the purpose of this utility model is to provide a kind of aluminium ash device for removing slag utilizing lever principle, effectively can take the aluminium ash that to suspend above holding furnace high temperature aluminum liquid off, solve the halfway problem of holding furnace dead angle prepurging of producing aluminium ingot, thus reduction labor strength, extend holding furnace service life, ensure the timely prepurging of holding furnace, guarantee that aluminium ingot high-quality is steadily produced.
To achieve these goals, the technical solution adopted in the utility model is:
Utilize an aluminium ash device for removing slag for lever principle, comprise dolly 5, raking arm 1 that dolly 5 is skimmed, the one end of raking arm 1 of skimming arranges the handle 2 of transverse horizontal, and the other end of raking arm 1 of skimming is provided with blade 3, and blade 3 is for being evenly equipped with the rectangular steel plates of mesh.
Be provided with fulcrum below described raking arm 1 of skimming, the distance of fulcrum and handle 2 is less than the distance of fulcrum and blade 3.
Balancing weight 6 is at one end provided with at described raking arm 1 upper handle 2 of skimming.
Compared with prior art, the beneficial effects of the utility model are:
(1) solve the not thorough phenomenon of the holding furnace dead angle prepurging producing aluminium ingot, reach reduction labor strength, extend the object in holding furnace service life.
(2) after improving, because dead angle lime-ash cleans out in time, holding furnace combustion space increases than before, join before the qualified high temperature aluminum liquid furnace charge of a stove is comparatively transformed and increase 5 tons, aluminium ingot scaling loss is impelled to reduce 0.5 ‰, annual by 300,000 tons of aluminium ingots calculating, the whole year hands over 150 tons, storehouse aluminium ingot more, brings benefits more than 1,800,000.
(3), after improving, because prepurging efficiency and effect improve, the door opened number of times of holding furnace is reduced, ton aluminium ingot natural gas unit consumption decline 2.5m
3/ t-al, further promotes aluminium electroloysis industry energy conservation consumption reduction, controls the realization of losing net income increase management objectives.
(4) substantially increase the production work efficiency of holding furnace, joined once the qualified aluminium ingot of production and increased to 56 dishes by 52 dishes, improve production team fine-grained management level.
(5) contribute to enterprise and reduce ton aluminium ingot production cost, in the fierce market competition in low margin age, rank among the forward position of world aluminum industry development.

Detailed description of the invention
Embodiment of the present utility model is described in detail below in conjunction with drawings and Examples.
As shown in Figure 1, Figure 2 and Figure 3, a kind of aluminium ash device for removing slag utilizing lever principle, comprises dolly 5, dolly 5 to be skimmed raking arm 1, skim one end of raking arm 1 arranges the handle 2 of transverse horizontal, and the other end of raking arm 1 of skimming is provided with blade 3, and blade 3 is for being evenly equipped with the rectangular steel plates of mesh.Wherein:
1. to skim raking arm 1: adopt diameter 80mm, wall thickness 6mm, the steel pipe of long 12000mm, can guarantee that raking arm is the temperature-resistant shape of 800 DEG C.
2, handle 2: conveniently operating personnel, adopt diameter 50mm, long 800mm, the steel pipe that wall thickness 3mm is thick is made.
3. blade 3: for being evenly equipped with the rectangular steel plates of mesh, the thick 6mm of steel plate, size is 1200 × 300mm; Mesh aperture
pitch-row 76mm.The effect of mesh is formation sieve-like grid, and high temperature aluminum liquid is flowed back in holding furnace from lime-ash.
4. dolly 5: be made up of handcart lower wall and the real core tire of handcart.For guaranteeing a kind of mobility and the flexibility that utilize lever principle aluminium ash device for removing slag, the handcart lower wall that radius is 26cm is installed under support.For guaranteeing a kind of flexibility and the heat-resisting quantity that utilize lever principle aluminium ash device for removing slag, handcart lower wall being installed the real core tire that radius is the quality of rubber materials of 26cm, can ensure that tire normally uses in high temperature aluminum lime-ash scald situation, normal production can not be affected.
In order to strengthen intensity and balance, in the welding lacing wire 4 of blade 3 both sides, its steel pipe material is Q235 steel.
As shown in Figure 4, be provided with fulcrum below raking arm 1 of skimming, the distance of fulcrum and handle 2 is less than the distance of handle 2 blade 3.In practical application, fulcrum is placed on the position at distance about 7.5 meters of of blade 3.Now operate and comparatively require great effort, therefore balancing weight 6 can be at one end set at raking arm 1 upper handle 2 of skimming.Balancing weight 6 gross weight 10kg, by regulating shelves 7 to regulate concrete weight, thus it is laborsaving to reach manual operation, does not affect the object of all functions.
