Abstract
The utility model discloses a degassing device for casting an aluminum alloy, which mainly solves the problem of incapability of removing impurities such as excessive hydrogen and the like in aluminum liquid. The degassing device comprises a chute arranged between an aluminum melting furnace and a casting machine, wherein a degassing box is arranged on the chute; a spray head capable of blowing the gas in the chute is fixed on the degassing box; and the spray head is connected to a gas source. According to the utility model, a large amount of dispersed small bubbles are formed in the aluminum liquid by the nitrogen or the inert gas through a rotary rotor spray head, so that the hydrogen is diffused into the small bubbles and float to the surface of a melt along with the small bubbles, thus the hydrogen is removed; meanwhile, a part of slag inclusions are taken from the melt in a floating process of the bubbles through the surface tension of the bubbles, so that the aluminum melt is refined. The degassing device, provided by the utility model has the advantages of safety, reliability and simple operation.

Summary of the invention
The main purpose of the utility model is to provide a kind of degasifying device, and it is mainly used in removes the impurity such as hydrogen of sneaking in the aluminium liquid, to reach the purpose to refining aluminium fusant.
The utility model provides a kind of degasifying device of used in aluminium alloy casting, comprises the chute that is arranged between molten aluminium stove and the casting machine, and degasification tank is installed on the chute; Degasification tank is fixed with the shower nozzle of blowing to chute interior; Shower nozzle connects source of the gas.
Wherein, in the described shower nozzle rotor is housed.
Preferably, described rotor is a graphite rotator.
In addition, described source of the gas comprises source nitrogen or inert gas source.
Preferably, described shower nozzle has a plurality of, is separately positioned on the chute both sides.
In addition, the described slag case that on degasification tank, also is provided with.
Compared with prior art, the beneficial effect of the utility model is:
1, the utility model forms the small bubbles of a large amount of disperses with nitrogen or rare gas element through the rotating rotor shower nozzle in aluminium liquid, and hydrogen is spread in small bubbles, along with small bubbles float to bath surface, thereby reaches the purpose of dehydrogenation.In the process of bubble floating, rely on bubble surface tension force to take a part of slag inclusion out of melt simultaneously, reach purpose refining aluminium fusant.Safe and reliable, operate simple and easy.
2, degasifying device is designed with a plurality of in the utility model; In chute, adopted a plurality of graphite rotators to carry out degasification: through the high speed rotating of graphite rotator; Make nitrogen or rare gas element in degasification tank, form a large amount of convection current; The small bubbles that form are able to abundant diffusion in aluminium liquid, increased the contact surface of bubble and aluminium liquid; Simultaneously the degasification casing adopts the design of sealing undercurrent type, has stopped the secondary pollution that the entering because of outside air causes, and has improved the degassing efficiency of equipment widely.
3, the utility model device is particularly useful for the narrower and small situation in place, workshop; Capital construction work amount in the time of can reducing scrap build; Simultaneously can satisfy the demands of different of user to ingot quality, make aluminium liquid directly through and do not carry out refine on line, thereby reduce the production cost of enterprise.

Fig. 1 is the structural representation that the utility model is used.
Description of reference numerals among the figure: 1, casting machine; 2, molten aluminium stove; 3, chute; 4, graphite rotator; 5, slag case; 6, shower nozzle; 7, degasification tank.
Embodiment
Be elaborated below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that following illustrated preferred embodiment only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 1; The utility model provides a kind of degasifying device of used in aluminium alloy casting, comprises the chute 3 that is arranged between molten aluminium stove 2 and the casting machine 1, and degasification tank 7 is installed on the chute 3; Degasification tank 7 be provided with in chute aluminium liquid, blow shower nozzle, rotor is installed in the shower nozzle; Shower nozzle 6 connects source nitrogen.
Shower nozzle can 6 be provided with a plurality ofly, and of Fig. 1, shower nozzle 6 is arranged on chute 3 both sides symmetrically, and every side is provided with 4, the supply of nitrogen in aluminium liquid.
Wherein, slag case 5 is set also on the chute 3, is used to collect aluminium liquid waste residue, reach aluminium liquid refining purpose; And shower nozzle 6 is tightly connected with chute 3.
The preferred graphite rotator 4 of rotor, high temperature resistant, long service life.The puff port of shower nozzle 6 is arranged on aluminium liquid bottom.
During concrete the application; The degasification tank of band rotor nozzle 6 is installed on the chute 3 between molten aluminium stove 2 and the casting machine 1; Melt aluminium flow is through degasification tank, and nitrogen passes through rotating rotor shower nozzle 6 forms a large amount of disperses in aluminium liquid small bubbles, and hydrogen is spread in small bubbles; Along with small bubbles float to bath surface, thereby reach the purpose of dehydrogenation.In the process of bubble floating, rely on bubble surface tension force to take a part of slag inclusion out of melt simultaneously, reach purpose refining aluminium fusant, safe and reliable, operate simple and easy.
The utility model degasifying device adopts the multi-stage degassing design; In chute, adopted a plurality of graphite rotators 4 to carry out degasification: through the high speed rotating of graphite rotator 4; Make nitrogen in degasification tank, form a large amount of convection current; The small bubbles that nitrogen forms are able to abundant diffusion in aluminium liquid, increased the contact surface of bubble and aluminium liquid; Simultaneously the degasification casing adopts the design of sealing undercurrent type, has stopped the secondary pollution that the entering because of outside air causes, and has improved the degassing efficiency of equipment widely.
Adopt the method for chute degasification, cancelled the necessary aluminium liquid of common refine on line equipment heat tracing system, reduced the power consumption of equipment use to greatest extent.
