Embodiment 1

[0043] see Figure 1-6 As shown, this embodiment is an operation method and separation working principle of an aluminum-iron separation device for automatic melting of recycled aluminum:

[0044] The model of stirring motor 103 among the present invention is YCT400-4A speed regulating motor;

[0045] When using the aluminum-iron separation device of the present invention, at first the waste aluminum material is dropped into the smelting and separation furnace 1 through the feeding pipeline 101, and then the stirring motor 103 and the electric heating block 105 are turned on to heat and smelt the waste aluminum material in the furnace while stirring, so that Its smelting is more complete and thorough; the smelting temperature is controlled at 660 to 760 degrees Celsius to ensure that the state of aluminum and iron is significantly different, which is convenient for separation; At this time, the smelting separation furnace 1 and the auxiliary separation box 203 communicate with...

Abstract

The invention discloses an automatic secondary aluminum smelting aluminum and iron separation device and relates to the technical field of secondary aluminum smelting. The automatic secondary aluminumsmelting aluminum and iron separation device comprises a smelting separation furnace and a separation device, wherein a stirring motor is mounted on the surface of the smelting separation furnace andan electric heating block is mounted in the smelting separation furnace. By arranging the smelting separation furnace and the separation device which communicate to each other, in a process of smelting aluminum waste to separate iron impurities, secondary aluminum is purified favorably by means of two-stage separation, so that the separation efficiency is improved. By arranging a stirring motor,aluminum waste can be fully and completely smelted by the smelting separation furnace under the stirring action. Meanwhile, by forming a filter hole, it is convenient to separate fully smelted moltenaluminum from the iron impurities and the molten aluminum flows into an auxiliary separation box along a separation channel for further separation treatment. By arranging the auxiliary separation box,the molten aluminum is cooled and condensed to a solid quickly by a method of injecting a cooling liquid and an electrolyte into the box, and micro impurities on the surface of the molten aluminum are separated out by the electrolyte for separation.

Description

technical field [0001] The invention belongs to the technical field of separation of recycled aluminum, aluminum and iron, in particular to an aluminum and iron separation device for automatic melting of recycled aluminum. Background technique [0002] In the prior art, in addition to direct smelting from bauxite in the industrial production of aluminum, waste aluminum can also be used to produce recycled aluminum. Recycled aluminum is an aluminum alloy or aluminum metal obtained by re-melting and refining waste aluminum and aluminum alloy materials or aluminum-containing waste materials. It is an important source of metal aluminum. Secondary aluminum comes mainly in the form of aluminum alloys. Generally, waste aluminum can be smelted into wrought aluminum alloy, cast aluminum alloy and deoxidizer for steelmaking. In addition, leaching and dry methods (crushing, screening and magnetic separation) can also be used to recover small aluminum particles from dross and slag. ...
