Description
Technical field
The present invention relates to useless magnesium material recovery and utilization technology field, particularly relate to a kind of useless magnesium material automatic recycling equipment.
Background technology
More than 90% of whole Magnesium Alloys Components is accounted at present by the Magnesium Alloys Components of Die Casting, in order to the needs of melt alloy filling die cavity when die casting, higher scrap rate is often obtained in the Die Casting process of magnesium alloy parts, be generally the 40%-60% of total metal input amount, and the overwhelming majority magnesium material that gives up that die casting produces is clean high-level waste, how extremely crucial effect is served to the total cost that this part useless magnesium material reclaims for product.
Traditional useless magnesium material recovery system, normally discontinuous or the fusing of semicontinuous smelting furnace are adopted to useless magnesium material, remove the impurity in magnesium liquid, and impurity is converted to bits removal by certain mode, and carry out the magnesium liquid through purification and impurity removal to turn liquid and ingot casting, thus useless magnesium material is re-used.At present, the process turning liquid and ingot casting often adopts pump to realize, series of problems is there is: first in reality is produced, turn blocking and the fault of liquid pump, pump structure is by driven by motor wheel rotation, magnesium liquid is made to enter into carrier pipe by impeller, be transported in crucible in holding furnace or ingot mold again, due to the magnesium liquid very thickness of fusing, and its inside can produce certain magnesium slag, very easily stick on impeller, as cleared up not in time, then can cause the blocking of the pump housing, all to clear up the pump housing after turning liquid ninety-nine times out of a hundred, consume a large amount of artificial and time, cleaning difficulty is also very large.And along with the growth of pump housing duration of service, impeller continues to rotate wearing and tearing, wheel sheet can be caused thinning, thus cause the pump housing not block, but turning liquid measure reduces, and has a strong impact on the working efficiency turning liquid.Once the pump housing blocks, or load reduces, then need to propose the pump housing, check it, checks that whether will change the pump housing still needs to clear up the magnesium slag of internal residual, complicated operation, and changes that to turn liquid pump cost very high, is unfavorable for production work.
In addition, traditional useless magnesium material retrieving arrangement operation easier is large, traditional take-back model is by the self-supporting material loading of workman, calciner melts, removal of impurities, holding furnace precipitates, filter, whole process all will workman's manual operation, use pump to carry out turning liquid to need each calciner at least to want 2 workmans to carry out compounding practice just to complete, especially the process removing bits is very arduous, because body of heater is larger, there is in body of heater certain diameter and the degree of depth, at least 2 workmans are needed to coordinate, use very slightly and very long fastener for connection casher box, extend into melted magnesium liquid from fire door, the magnesium slag precipitating is picked up from bottom, to skim work.And temperature is higher after the fusing of magnesium liquid, about more than 700 degrees Celsius, execute-in-place environment very severe, causes operation irregularity difficulty of skimming.
Secondly, traditional useless magnesium material recovery system turns liquid owing to adopting by pump, has strict restriction to the useless magnesium material kind reclaimed, once reclaim the trade mark and the composition transfer of useless magnesium material, so comprise the crucible in stove, the pump housing all will comprehensively clear up, avoid being polluted by old material, and large owing to clearing up difficulty, and easy to clean does not thoroughly cause new product composition tolerances, and the cleaning work of equipment is complicated, cleaning difficulty is very large, delays the production time, incurs loss through delay production schedule.
Summary of the invention
The object of the invention is to the deficiency for general useless magnesium material recovery system, a kind of useless magnesium material automatic recycling equipment is provided, by calciner and holding furnace are flexibly connected with support respectively, and guide rail is set makes holding furnace arrive the position corresponding with calciner along guide rail, there is provided power to make calciner overturn certain angle by atmospheric pressure pole thus the magnesium liquid in calciner is directly proceeded in holding furnace without pump and transport pipe, magnesium liquid is also transferred in corresponding casting unit by moving and overturning by holding furnace simultaneously, in addition, calciner, holding furnace and atmospheric pressure pole etc. are all connected with PLC and are controlled by PLC, realize the automatic of useless magnesium material, recovery without pump production line.
Another object of the present invention is, by the bottom surface of holding furnace is set to inclined-plane, and by discharge port is arranged on position higher on inclined-plane, make the magnesium liquid liquid level of holding furnace in normal state in it lower than the position of discharge port, when needing magnesium liquid to produce, only needing holding furnace to be carried out suitable upset makes magnesium liquid reach the position of discharge port, simultaneously opening encapsulation plug, and it is extremely convenient to operate.
Another object of the present invention is, after the magnesium liquid in calciner produces, bits remain in body of heater, and calciner is turning, need not carry out dragging for slag from the magnesium liquid of high temperature, greatly reduce the difficulty of the work of skimming, and improves the efficiency of work of skimming.
