Further, in order to ensure temperature, improving heat utilization ratio, energy efficient, the top of described refining chamber and described intensification filter chamber is respectively equipped with heat storage simultaneously.
It is mainly composed of aluminium oxide due to impurity, generally swim in the surface of aluminum liquid, therefore to avoid the mutual flowing pollution of impurity, described melting chamber and described refining chamber, described refining chamber with described go out liquid well, described in go out liquid well and described aluminum bits melting chamber, described aluminum bits melting chamber and described slagging-off room, described slagging-off room and be respectively adopted bottom between described intensification filter chamber, described intensification filter chamber and described melting chamber and connect.
Further, it is contemplated that when aluminum bits add, it is to avoid the aluminum liquid gone out in liquid well is polluted by aluminum bits with flowing, described circulation canal from described in go out the bottom of liquid well and consider the tilted setting of melting chamber to be worth doing to described aluminum.
Further, described liquid outlet channel is positioned at above described circulation canal and adapts with aluminum liquid liquid level.
Further, aluminum bits dosing operation and slagging-off operation for convenience, the top of described aluminum bits melting chamber has aluminum bits dog-house, and the top of described slagging-off room has slagging-off mouth.
A kind of aluminum melting method of the present invention, is included feed process, melting process, refining procedure successively and goes out liquid operation by process sequence, goes out and is provided with circulating process between liquid operation and thawing operation.This aluminium melting furnace includes feeding-passage, feeding-passage connects with melting chamber, melting chamber connects with refining chamber, refining chamber is communicated with out liquid well, go out liquid well and be respectively provided with liquid outlet channel and circulation canal, circulation canal connection aluminum bits melting chamber, aluminum bits melting chamber connection slagging-off room, connection intensification filter chamber, slagging-off room, intensification filter chamber is connected with melting chamber.By increasing circulating process, increasing technology chain, the process making aluminum liquid melt obtains self-loopa and adjusts, and flowing time and the flow path of aluminum liquid increase the most accordingly, and aluminum liquid refines more consummate, impurity thus obtain deeper into ground filtration.Realize completing of the method by this aluminium melting furnace simultaneously, thus the impurity content in aluminum liquid when reducing out liquid.

Detailed description of the invention
Below according to drawings and Examples, the present invention is described in further detail.
As it is shown in figure 1, a kind of aluminum melting method described in the embodiment of the present invention, include feed process, melting process, refining procedure by process sequence successively and go out liquid operation, going out and be provided with circulating process between liquid operation and thawing operation.By increasing circulating process, increasing technology chain, the process making aluminum liquid melt obtains self-loopa and adjusts, and flowing time and the flow path of aluminum liquid increase the most accordingly, and aluminum liquid refines more consummate, impurity thus obtain deeper into ground filtration.
Also can melt further in view of the aluminum bits often remained in process of manufacture, simultaneously take account of the demand needing timing removal of contamination to pile up slagging, circulating process includes that aluminum considers melting process, slagging-off operation and intensification filter progress to be worth doing successively.
Shown in Fig. 2, Fig. 3, Fig. 4 and Fig. 5, use the aluminium melting furnace of above-mentioned aluminum melting method, including feeding-passage 1, feeding-passage 1 connects with melting chamber 2, and melting chamber 2 connects with refining chamber 3, refining chamber 3 is communicated with out liquid well 4, going out liquid well 4 and be respectively provided with liquid outlet channel 9 and circulation canal 10, circulation canal 10 connects aluminum bits melting chamber 5, aluminum bits melting chamber 5 connection slagging-off room 6, slagging-off room 6 connects intensification filter chamber 7, and intensification filter chamber 7 is connected with melting chamber 2.
In order to ensure temperature, improving heat utilization ratio, energy efficient, the top of refining chamber 3 and intensification filter chamber 7 is respectively equipped with heat storage 8 simultaneously.
It is mainly composed of aluminium oxide due to impurity, generally swim in the surface of aluminum liquid, therefore to avoid the mutual flowing pollution of impurity, melting chamber 2 and refining chamber 3, refining chamber 3 and go out liquid well 4, go out liquid well 4 and connect with being respectively adopted bottom between intensification filter chamber 7, intensification filter chamber 7 and melting chamber 2 with slagging-off room 6, slagging-off room 6 with aluminum bits melting chamber 5, aluminum bits melting chamber 5.Liquid outlet channel 9 is positioned at above circulation canal 10 and adapts with aluminum liquid liquid level.
Recombining shown in Fig. 5, it is contemplated that when aluminum bits add, it is to avoid the aluminum liquid gone out in liquid well 4 is polluted by aluminum bits with flowing, circulation canal 10 considers the tilted setting of melting chamber 5 from the bottom going out liquid well 4 to be worth doing to aluminum.
Aluminum bits dosing operation and slagging-off operation for convenience, the top of aluminum bits melting chamber 5 has aluminum bits dog-house 51, and the top of slagging-off room 6 has slagging-off mouth 61.
By increasing circulating process, increasing technology chain, the process making aluminum liquid melt obtains self-loopa and adjusts, and flowing time and the flow path of aluminum liquid increase the most accordingly, and aluminum liquid refines more consummate, impurity thus obtain deeper into ground filtration.Realize completing of the method by this aluminium melting furnace simultaneously, thus the impurity content in aluminum liquid when reducing out liquid.
The foregoing is only explanation embodiments of the present invention; be not limited to the present invention, for a person skilled in the art, all within the spirit and principles in the present invention; the any modification, equivalent substitution and improvement etc. made, should be included within the scope of the present invention.
