Description
Technical field
This utility model belongs to aluminum processing technology field, is specifically related to a kind of aluminum loss of thick fluid hydrogen production device.
Background technology
Aluminium alloy, when melting and cast, can suck substantial amounts of hydrogen, then constantly separate out because of the decline of dissolubility during cooling.The hydrogen dissolved in aluminium alloy, its dissolubility increases with the rising of aluminium alloy temperature, reduces with the decline of temperature, liquid, when being transformed into solid-state, hydrogen dissolubility in aluminium alloy declines 19 times.Therefore aluminum alloy melt is during cooled and solidified, and when the content of hydrogen has exceeded its dissolubility, the form with bubble separates out.The bubble hydrogen formed because of oversaturated hydrogen evolution, discharging if having little time to float, will form pore tiny, scattered, the most usually said pin hole in process of setting.
A kind of online dehydrogenation device of aluminum liquid is disclosed in the domestic patent of Application No. 201420252277.9, mainly type uses bicavate degassing tank, and Electromagnetic Drive, ultrasonic activation degasification, inert gas deaeration, spray degasification, centrifugal force degasification, vacuum degassing technology set are integrated, reach optimal degassing effect.But being devices which the hugest, processing cost is too high, and operating the most complex, in the aluminium manufacturer that some are small-sized, use cost is the highest.
Utility model content
This utility model is intended to provide a kind of aluminum loss of thick fluid hydrogen production device, the hugest to solve present aluminum liquid dehydrogenation device, operation complexity, the problem that enterprise's input cost is the highest.
A kind of aluminum loss of thick fluid hydrogen production device in this programme, including sealed dehydrogenation tank, described dehydrogenation tank includes top board and the sidewall of annular, described top board is provided with the shaft for stirring aluminum liquid, described shaft is provided with blade, the motor being arranged over driving shaft to rotate of described top board, described top board is provided with suction opeing, described suction opeing connects air draft pipe, described air draft pipe connects air exhauster, the upper end of described sidewall is provided with inlet, the lower end of described sidewall is provided with liquid outlet, described shaft and blade are provided with nickel base alloy layer, described nickel base alloy layer is tubulose, described nickel base alloy layer is threadeded with blade, described nickel base alloy layer is threadeded with shaft.
Operation principle of the present utility model:
nullBecause aluminum liquid can contact with oxygen forms one layer of aluminium oxide on aluminum liquid surface，The hydrogen in aluminum liquid is caused to be difficult to escape aluminum liquid，So the oxygen that sealed dehydrogenation tank can ensure that the external world cannot be introduced in dehydrogenation tank，Aluminum liquid flows into dehydrogenation tank from inlet，Shaft motor be rotated by stir aluminum liquid，The hydrogen dissolved in aluminum liquid is quickly escaped，And on the one hand the design of convulsion is to extract out the gas in dehydrogenation tank to go，It is in vacuum state in making tank，And the hydrogen stirring effusion is pumped rapidly，Do not have the chance that secondary dissolves，On the other hand dehydrogenation pressure inside the tank is reduced，And pressure low time，Hydrogen dissolubility in aluminum liquid can reduce，It is easier to effusion，Aluminum liquid after dehydrogenation flows out for following process from liquid outlet，Aluminum liquid is affixed owing to all can glue on shaft and blade，When after dehydrogenation end-of-job，The aluminum liquid being bonded on shaft and blade is oxidized to alumina layer，Tradition is removed the mode of aluminium oxide and is bothered very much，And by the design of nickel base alloy layer，Aluminium oxide will be attached to the surface of nickel base alloy layer，When we need to clear up aluminium oxide，Nickel base alloy layer is taken off from shaft and blade，Owing to being threaded，Therefore take off and be convenient to，The nickel base alloy layer taken off just can wash the aluminium oxide of surface attachment off by adding ammonia，The most again nickel base alloy layer set is connected on shaft and blade，Can be achieved with easily going alumina.
The beneficial effects of the utility model:
The technical solution of the utility model, rational in infrastructure, make such a installation cost the lowest, in adding stirring dehydrogenation and tank, vacuum environment reduces hydrogen solubility, therefore the efficiency of dehydrogenation is the highest, through the aluminum liquid of the technical program dehydrogenation, dehydrogenation rate can reach more than 98%, therefore can be widely used in middle-size and small-size aluminium manufacturer, for traditional dehydrogenation unit, floor space, input cost all has substantial degradation, and can very comfortable remove the aluminium oxide of attachment on shaft and blade.
Further, described shaft is provided with application of anti-leakage layers with the contact position of top board, and this is the sealing in order to strengthen dehydrogenation tank further so that extraneous can not enter dehydrogenation tank from the contact position of shaft with top board in the air, keeps a good vacuum environment in tank.
Further, the top of described inlet and liquid outlet is equipped with slidably gas barrier, this is owing to the aluminum flow quantity when inlet or liquid outlet is less, whole inlet or liquid outlet cannot be blocked, so gas barrier is slided, can ensure that aluminum liquid can block inlet or liquid outlet all the time, extraneous air cannot propagate in dehydrogenation tank.
Further, described suction opeing flare, convulsion of being so more convenient for, the vacuum environment that the effect of convulsion is more thorough, good in keeping dehydrogenation tank.
Further, the distance of described inlet and liquid outlet in the vertical direction is 0.5m, and this is due to when when excessive, hydrogen effusion needs the distance grown very much, adds the difficulty of dehydrogenation, and when too small, the amount of aluminum loss of thick fluid hydrogen is the least, inefficient, and optimum distance is 0.5m.
