Description
Technical field
The utility model relates to a kind of purifying processing device of aluminium liquid, relates in particular to a kind of efficient, energy-conserving on-line degassing device.
Background technology
Because there are objectionable impuritiess such as hydrogen, Al2O3 inclusion in aluminium alloy after refining, defective such as in foundry goods, easily form pore, loosen, be mingled with, directly influence physicals, mechanical property and the use properties of aluminium casting, therefore must before casting, manage to remove these objectionable impuritiess.Aluminium melt purifying treatment technology commonly used at present has rotary blowing degassing and purifying method and gas permeable brick degassing and purifying method.Rotary blowing degassing and purifying method is the rare gas element chopping that will be blown into aluminium alloy melt in the degassing processing case by the graphite rotator of rotation, form a large amount of disperse bubbles, aluminum alloy melt is fully contacted in treating pond with nitrogen, bubble absorbs the hydrogen in the melt, and the surface that rises to melt after the oxide slag inclusion forms scum silica frost, thereby reaches the purpose of purifying aluminum alloy liquid.The main drawback of this method is that graphite rotator is changed frequently, and investment is big; The composition of aluminium liquid is polluted, and surface film oxide is destroyed, has increased the oxidation slagging scorification of aluminium liquid; The airing system air demand is limited, and degassing effect remains further to be improved.Gas permeable brick degassing and purifying method is pressed into rare gas element from degassing processing case bottom exactly, forms very little bubble by gas permeable brick and enters in the molten aluminium alloy, and the method for utilizing bubble to absorb hydrogen and oxide inclusion in floating-upward process purifies.But because aluminium liquid is immobilized, rare gas element can not with aluminium liquid thorough mixing, skewness in aluminium liquid, so degassing effect is undesirable.Chinese patent application number stirs online a refining unit for disclosing a kind of permanent magnetism in the application documents of ZL200620050898.4, though this device can carry out purifying treatment to aluminium liquid, but have the following disadvantages: 1, design is unreasonable, gas permeable brick places the permanent magnetic stirrer top, because the thickness of gas permeable brick own is big, add the thickness that annex such as required air-supply duct will increase the furnace wall greatly, want to make aluminium liquid to stir, more powerful permanent magnetic stirrer must be used, cost will be increased greatly like this; 2, the eddy current that in rotary course, produces of permanent magnetic stirrer, damage pipeline that will be serious causes line clogging, and air feed has some setbacks, and accident is frequent.
The utility model content
The purpose of this utility model provides a kind of online degasifying device, bad with the complex structure, the degasification slagging-off effect that overcome currently available products, as to need to drop into big cost deficiency.
The purpose of this utility model is to be achieved through the following technical solutions:
A kind of online degasifying device, comprise processing tank, processing case lid, inner chamber dividing plate, gas permeable brick, intelligent airing system, permanent magnetism rotator, heating U-shaped globars, the top of processing tank is provided with the processing case lid, the inner chamber dividing plate is divided into left and right two inner chambers that the bottom is connected with entire treatment box cavity body, wherein right intracavity bottom is equipped with gas permeable brick and intelligent airing system, and intelligent airing system connects gas permeable brick, supplied gas is by gas permeable brick access arrangement inside, and right inner bore cavity side is provided with aluminium liquid fluid inlet; Left side intracavity bottom is equipped with the permanent magnetism rotator, is provided with immerseable heating U-shaped globars in the cavity, and described globars is outside equipped with columniform silicon carbide or silicon nitride protective tube, and the side of left inner bore cavity is provided with liquid outlet.
The beneficial effect of a kind of online degasifying device described in the utility model is: the slagging-off degassing effect is good; Adopt controlled constant speed permanent magnetism rotator to carry out contactless stirring, save energy, reduced cost, improved aluminium liquid purity; Adopt heating U-shaped globars to heat, can keep the temperature of aluminium liquid; Easy to use, have wide expanding space.
