The utility model has the advantages of simple structure, low cost and good purifying effect, no temperature drop, convenient clean and maintenance for the furnace, etc. The continuously cleaning device for outside of al and al-alloy furnace is suitable for the alumina-bearing material processing industry with high requirement of the quality of aluminium, such as the extruded tubes, etc.
Description
The utility model relates to a kind of aluminium and alloy refining device.The continuous purification device outside line oven that has concurrently for a kind of degasification slagging-off.
In known purification aluminium and the aluminium alloy melt method of hydrogen and non-metallic inclusion be the batch-wise furnace purge and outside line oven continuous purification, be first reason wherein with the outer continuous purification technology of stove, good purification.That uses at present has based on the outer melt filtration device of the various stoves of slagging-off; The ALPUR device of the SNIF device of the U.S. combinating carbide company of making a living with degasification, France etc. is to adopt swivel nozzle ejection refining gas sweetening, this swivel nozzle complex structure, cost height, consumes soon, and device does not have filtration, purification to remove the gred weak effect.The MINT device of the U.S. associating Chinalco that the degasification slagging-off has concurrently makes the melt rotation by melt flow, and nozzle is arranged at the deaerating chamber bottom, and degassing effect is bad, and does not have attemperator, and the melt temperature drop is bigger.
The purpose of this utility model is intended to make improvements according to above-mentioned problems of the prior art, to obtain the continuous purification device outside line oven that a kind of good purification, simple in structure, prepurging maintenance degasification slagging-off convenient, that do not have temperature drop have concurrently, to satisfy the high-quality demand of modern aluminium processing industry.
For achieving the above object, the utility model proposes a kind of refining plant that has improved, it comprises deaerating chamber, deaerating chamber stirring mechanism and removes the grit chamber, it is characterized in that deaerating chamber and remove the grit chamber in same body of heater, one partition wall is arranged between them, leave passage between partition wall bottom and the body of heater bottom surface, remove slagging-off filtering surface in the grit chamber under the aluminum melt liquid level, on the partition wall bottom.The bottom is provided with the gaseous diffuser that refining gas big area evenly can be provided in the deaerating chamber.It above the body of heater bell of band well heater.Whole device is by bracket supports.
Accompanying drawing is depicted as the utility model structure construction synoptic diagram.
Below in conjunction with Figure of description and embodiment the utility model is done and to be described in further detail: as shown in drawings, the utility model mainly is made up of body of heater 3, bell 8, support 7, deaerating chamber stirring mechanism and the stirring system lifting support that is fixed on the bell 8.The deaerating chamber 1 of refining plant and remove grit chamber 2 in same body of heater 3 has partition wall 4 between them, partition wall 4 is the refractory materials precoated plate, is inserted in the fluting of both sides, furnace wall, leaves passage 5 between partition wall 4 bottoms and the body of heater bottom surface.Remove slagging-off filtering surface in the grit chamber 2 under the aluminum melt liquid level, on partition wall 4 bottoms, the bottom is provided with the gaseous diffuser 6 that refining gas big area evenly can be provided in the deaerating chamber 1.Scatterer 6 is made by breathable refractory materials, is fixed at the bottom of the body of heater under the vertical stir shaft 10 in the wall.The face of giving vent to anger of scatterer 6 is in the furnace bottom plane, and the below of its air inlet face is an air chamber 11, and air chamber 11 bottoms are provided with the inlet mouth 12 that communicates with the refining source of the gas that pressure is arranged.Scatterer 6 is the stopper body that air inlet face is big, the face of giving vent to anger is little, and the face of giving vent to anger is the garden shape close with stir shaft 10 end diameter.
For both sides on bell 8 bells 8 of band well heater scroll wheel 14 is housed above the body of heater 3 of refining plant, the slideway 15 that is provided with both sides, body of heater 3 upper end cooperates.Have a plurality of parallel fan-shaped open recess on the inwall of bell 8, heating unit globars 9 is set in the groove.
Refining plant integral body is by support 7 supportings, but support 7 is provided with the body of heater tilting mechanism 13 of the turbine worm transmission of self-locking, and its structure construction is identical with the tilting mechanism of various molten metal bags.
Body of heater 3 is refractory concrete-refractory brick-aluminosilicate property thermal insulation layer-box hat structure, and the shell of bell 8 is a cast steel, in case thermal distortion.The deaerating chamber stirring mechanism comprises fire-resistant stir shaft 10, coupling shaft, motor and wheel box, and the place of passing bell 8 is the junction of coupling shaft and fire-resistant stir shaft 10, is provided with refractory protection cover 16.The stirring system lifting support comprises column 17, lifting shaft 18, motor and wheel box.
Aluminium liquid is from the 19 inflow deaerating chambers 1 that enter the mouth, mixed nitrogen chlorine refining gas is blown into the thin bubble that looses by the scatterer 6 of furnace bottom in molten aluminium, bubble adverse current in aluminium liquid slowly floats, the stir shaft of pressing the certain speed rotation stirs rotation with melt, simultaneously with the further broken tiny bubble rotation come-up that forms of the bubble of refining gas, increase the contact area of bubble and melt like this, prolonged the residence time of small bubbles in melt, can improve the gas cleaning effect greatly.Bubble utilizes partial pressure difference degasification principle and absorption slagging-off principle degasification slagging-off in the floating-upward process in melt, melt is carried out purifying the first time.Flowed into filtration chamber 2 by the melt after the gas sweetening through stove internal partition wall bottom, filter through floamed ceramics filtrating piece or micropore ceramic tube 20 again, utilize the filter cleaner principle that melt is carried out secondary-cleaned.Melt through secondary-cleaned directly enters casting machine by outlet 21 outflows.
Compared with prior art, the utility model has mainly adopted degasification to establish the methods such as refining gas diffuser, bell heating constant-temperature system except one, deaerating chamber in grit chamber's stove, make the characteristics such as simple and reasonable, that cost is low, do not have temperature drop, the prepurging maintenance is convenient that the utlity model has, good purification particularly, use is produced extrude tubes through the aluminium liquid that this device purifies, yield rate brings up to 90% by 40-50%, the economic benefit highly significant.
