Technical field
The present invention relates to a kind of metal molten stove, be used in particular for the fusing of aluminium.
Background technology
The metal molten stove adopting at present, as for melting aluminum, it comprises aluminium water intensification chamber, pump chamber, minor air cell and aluminium slag intensification chamber, aluminium water intensification chamber is provided with burning nozzles, large fire door and aluminium water out one, aluminium slag intensification chamber is provided with little fire door and aluminium water out two, and aluminium water intensification chamber is connected with pump chamber, and pump chamber is connected with minor air cell, minor air cell is connected with aluminium slag intensification chamber, is provided with flue and aluminium water circulation road between aluminium water intensification chamber and aluminium slag intensification chamber.
In the process of melting aluminum, the cyclic process of aluminium water in metal molten stove is: aluminium water heating furnace → pump chamber → minor air cell → aluminium slag intensification chamber → aluminium water scum silica frost separate tank → aluminium water intensification chamber.In above-mentioned, as the aluminium slag that floats over aluminium water surface too much and do not remove in time, in aluminium water intensification chamber and aluminium slag intensification chamber, can burn (being so-called scaling loss), the rate of recovery of reduction aluminium, therefore, need remove aluminium slag in time, and remove time need to first close burning nozzles, open respectively large fire door and little fire door, by large fire door and little fire door and adopt artificial or fork truck to claw aluminium slag, like this, not only take a lot of work but also time-consuming, labour intensity is large; , then rekindle after burning nozzles, the scum silica frost that does not remove with the small part that aluminium slag intensification chamber exists aluminium water intensification chamber, because directly contacting with naked light, also can further be accelerated scaling loss, and the programming rate of melting furnace is slowed down meanwhile.
Summary of the invention
The object of this invention is to provide descum convenient, and a kind of metal molten stove that scum silica frost can be separated completely with metal water.
The technical scheme that the present invention takes is: a kind of metal molten stove, comprise aluminium water intensification chamber, pump chamber, minor air cell and aluminium slag intensification chamber, aluminium water intensification chamber is provided with burning nozzles, large fire door and aluminium water out one, aluminium slag intensification chamber is provided with little fire door and aluminium water out two, aluminium water intensification chamber is connected with pump chamber, pump chamber is connected with minor air cell, minor air cell is connected with aluminium slag intensification chamber, between aluminium water intensification chamber and aluminium slag intensification chamber, be provided with flue, characterized by further comprising metal water scum silica frost separation chamber, between metal water scum silica frost separation chamber and regulus intensification chamber, be provided with regulus aquaporin, between metal water scum silica frost separation chamber and metal water intensification chamber, be provided with metal water circulation road, the bottom in metal water circulation road is higher than the bottom of metal water scum silica frost separation chamber, and in metal water scum silica frost separation chamber and the front portion in metal water circulation road be only provided with in bottom, metal water scum silica frost separation chamber and there is uncovered baffle plate, the bottom in metal water circulation road or part bottom are higher than the bottom of this baffle plate.
Described regulus passage is provided with gate.
Adopt the present invention, can in stove, realize separating of metal water and shruff, can directly in metal water scum silica frost separation chamber, pull shruff out, carry out again the removing of shruff without closing burning nozzles, both convenient, simple, time saving and energy saving again, can effectively improve the rate of recovery.
