[0073] During operation, the power generation component is electrically connected to the rotating component, the filtering component and the gas transmission component. Under the action of the power generation component, the rotating component starts to rotate, and the rotating component drives the filtering component and the gas transmission component to rotate together. When it is necessary to collect and filter the residue generated by oxidation after the aluminum liquid is heated, the filtering component first freely extends into the liquid storage component in the vertical direction under the action of electricity, and then the heating component heats the aluminum liquid in the liquid storage component.

When in use, the wires in the power generation box 502 are arranged through the wire storage box 501 to connect with other components for power supply, so as to facilitate the control of the operation of different components.

[0078] The gas storage assembly is arranged on the top wall of the power generation assembly, and the gas storage assembly includes: a gas storage box 601, a nitrogen bottle 602, an air delivery pipe 603 and a control valve 604.

When in use, the transmission line inside the supporting base 201 passes through the through hole between the circular hole 102 and the rectangular hole 101 to connect with the power generation box 502, and the supporting base 201 is controlled to rotate by electricity, and the supporting base 201 drives the rotating column 202 and the L-shaped plate 203 to rotate together.

[0080] The filter assembly is arranged at one end of the L-shaped plate 203, and the filter assembly includes: a telescopic column 301, a fixed rod 302, a fixed frame 303 and a filter screen 304. One end of the telescopic column 301 is fixedly connected to one end of the L-shaped plate 203, one end of the fixed rod 302 is fixedly connected to the telescopic column 301, and the fixed frame 303 is fixedly connected to the other end of the fixed rod 302, wherein the fixed frame 303 is a square, and there are 4 fixed rods 302, which are respectively fixedly connected to the four corners of the fixed frame 303.

When in use, the support base 201 is controlled to rotate by electricity, and the support base 201 drives the rotating column 202 and the L-shaped plate 203 to rotate together, and the L-shaped plate 203 drives the telescopic column 301 to rotate. During the rotation, the filter 304 is placed at the opening position above the heating barrel 801, and electricity is transmitted to the telescopic column 301 through the power generation box 502, so that the telescopic column 301 extends downward until the fixing frame 303 and the filter 304 are placed in the aluminum liquid in the heating barrel 801, and the aluminum liquid in the heating barrel 801 is heated. After residue is generated to a certain extent, the telescopic column 301 is controlled by electricity to shrink upward to drive the filter 304 to move upward, and the residue floating on the surface of the aluminum liquid is taken away during the upward movement of the filter 304.

[0081] The gas delivery assembly is arranged at the other end of the L-shaped plate 203, and the gas delivery assembly includes: a first covering plate 701, a second covering plate 702 and a telescopic tube 703. The top of the first covering plate 701 is fixedly connected to the other end of the L-shaped plate 203, and the top of the second covering plate 702 is telescopically connected to the bottom of the first covering plate 701. The telescopic tube 703 is arranged at the bottom of the second covering plate 702, and passes through the second covering plate 702 and the first covering plate 701 and is fixedly connected to the air supply pipe 603. When in use, the support base 201 is controlled to rotate by electricity, and the support base 201 drives the rotating column 202 and the L-shaped plate 203 to rotate together, and the L-shaped plate 203 drives the first covering plate 701 to rotate. During the rotation process, the first covering plate 701 is placed at the opening position above the heating barrel 801, and electricity is transmitted to the telescopic tube 703 through the power generation box 502, so that the telescopic tube 703 extends downward until the telescopic tube 703 enters the refined liquid in the heating barrel 801. At this time, the second covering plate 702 covers the opening of the heating barrel 801, and the control valve 604 is turned to open the nitrogen bottle 602 to inject nitrogen into the refined liquid in the heating barrel 801 through the air supply pipe 603 and the telescopic tube 703. The nitrogen forms a large number of bubbles in the aluminum liquid. In these nitrogen bubbles, the hydrogen partial pressure is equal to zero, so the hydrogen in the refined liquid will diffuse into the bubbles, thereby removing the gas in the refined liquid.

[0082] When the embodiment of the present application is in operation, the external gas storage device delivers gas to the heating box 401 through the connecting pipe 402. The gas burns in the heating box 401 to generate heat, and heats the aluminum liquid in the heating barrel 801 arranged in the heating tank 403. The heating tank 403 wraps the heating barrel 801.

After residue is generated to a certain extent, the telescopic column 301 is controlled by electricity to shrink upward to drive the filter 304 to move upward, and the residue floating on the surface of the aluminum liquid is taken away during the upward movement of the filter 304.

[0083] Refined liquid is added into the heating barrel 801 through the liquid inlet pipe 803. When the refined liquid needs to be degassed, the support base 201 is rotated by electric control. The support base 201 drives the rotating column 202 and the L-shaped plate 203 to rotate together. The L-shaped plate 203 drives the first covering plate 701 to rotate. During the rotation, the first covering plate 701 is placed at the opening position above the heating barrel 801. Electricity is transmitted to the telescopic tube 703 through the power generation box 502, so that the telescopic tube 703 extends downward until the telescopic tube 703 enters the refined liquid in the heating barrel 801. At this time, the second covering plate 702 covers the opening of the heating barrel 801. The control valve 604 is turned to open the nitrogen bottle 602 to inject nitrogen into the refined liquid in the heating barrel 801 through the gas supply pipe 603 and the telescopic tube 703. The nitrogen forms a large number of bubbles in the refined liquid. In these nitrogen bubbles, the hydrogen partial pressure is equal to zero. Therefore, the hydrogen in the refined liquid will diffuse into the bubbles, thereby removing the gas in the refined liquid.

By rotating the rotating component, the device can be controlled to perform filtering or degassing. The entire filtering and degassing operation process can be completed independently by this device without the help of external equipment, meeting the needs of residue filtering of molten aluminum or removing gas from molten aluminum within the optimal time period.
