[0013] A method for using an integrated device for opening the cover of an aluminum smelting furnace and removing slag, comprising the following steps: S1: After the smelting furnace completes the smelting of aluminum, the residue gathers on the upper surface of the aluminum liquid. At this time, the liquid level sensor detects the liquid level of the aluminum liquid and transmits the detected electrical signal to the digital display control panel. The digital display control panel controls the extension of the first electric telescopic rod push rod of the lifting drive assembly, thereby driving the double-helix slag scooping structure to move downward, so that the bottom side of the double-helix slag scooping structure contacts the upper surface of the residue; S2: The first rotary motor of the hanger assembly drives the furnace cover to rotate, so that the block slides in the tightening chute until the block rotates to the position of the inlet and outlet notch provided at the end of the tightening chute.

The lever shaft of the lever lever assembly is driven by the second electric telescopic rod to be inserted into the pitch gap between the first spiral slag scooping rib plate and the second spiral slag scooping rib plate. The double-helix slag scooping structure is driven upward by the first electric telescopic rod, and the double-helix slag scooping structure is driven to rotate by the first rotating motor, so that the lever shaft pushes the slag spiral out and drops it onto the slag slide plate for extraction and collection.

[0014] The beneficial effects are: 1. Through the coordination and cooperation among the smelting furnace, furnace cover, lifting drive assembly, hanger assembly, material lever assembly and double-helix slag scooping structure, the slag on the surface of the aluminum liquid can be scooped while the furnace cover is opened, thereby avoiding excessive heat loss caused by the furnace cover being opened for too long, and realizing the automatic integration of smelting, opening the cover, slag scooping, aluminum liquid discharge and residue removal in the aluminum smelting furnace.

[0015] 2. The double-helix slag scooping structure can cooperate with the up and down drive of the lifting drive assembly to realize the spiral slag scooping of the residue during the rotation and opening of the furnace cover, and collect the residue at the pitch gap between the first spiral slag scooping rib plate and the second spiral slag scooping rib plate; 3.

The rod seat (703) is connected to more than two shifting rod shafts (704) for inserting into the pitch gap between the first spiral slag scooping rib plate (802) and the second spiral slag scooping rib plate (803). The output end of the digital display control panel (10) is electrically connected to the input end of the second electric telescopic rod (702).

9. The integrated device for removing slag from the cover of an aluminum smelting furnace according to claim 1, characterized in that: A residue slide plate (9) and a liquid level sensor (11) are respectively arranged on the outside of the smelting furnace (2); an output end of the liquid level sensor (11) is electrically connected to an input end of a digital display control panel (10); and a cross-sectional shape of the residue slide plate (9) is an arc.

10. A method for using an integrated device for removing slag from an aluminum smelting furnace by opening the cover, using the integrated device for removing slag from an aluminum smelting furnace by opening the cover according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: After the smelting furnace (2) completes smelting of aluminum, slag accumulates on the upper surface of the aluminum liquid. At this time, the liquid level sensor (11) detects the liquid level of the aluminum liquid and transmits the detected electrical signal to the digital display control panel (10). The digital display control panel (10) controls the first electric telescopic rod (403) of the lifting drive component (4) to extend, thereby driving the double-helix slag scooping structure (8) to move downward, so that the bottom side of the double-helix slag scooping structure (8) contacts the upper surface of the slag; S2: The first rotating motor (502) of the hanger assembly (5) drives the furnace cover (3) to rotate, so that the clamping block (303) slides in the tightening chute (204) until the clamping block (303) rotates to the position of the inlet and outlet notch (205) provided at the end of the tightening chute (204). During the above process, the push rod of the first electric telescopic rod (403) continues to extend, and the double-helix slag scooping structure (8) can rotate with the furnace cover (3), thereby realizing the collection of residues in the pitch gap between the first spiral slag scooping rib plate (802) and the second spiral slag scooping rib plate (803); S3: The water inlet pipe joint (404) is connected to the external cooling device and a cooling circulating agent is introduced. A water inlet pipe joint (404), two spring connecting pipes (405), two first water passages (406), a water outlet pipe joint (407), a first cooling cavity (409), a second cooling cavity (410) and a second water passage (411) form a cooling circulation channel, thereby cooling the residue in the first spiral slag scooping rib plate (802) and the second spiral slag scooping rib plate (803). When the first electric telescopic rod (403) drives the double spiral slag scooping structure (8) to move upward, the residue can be retained on the double spiral slag scooping structure (8) and carried away with the movement; S4: The second rotating motor (6) drives the smelting furnace (2) to flip up and down, pouring out the aluminum liquid in the smelting furnace (2), and during this process, the residue slide plate (9) is located directly below the double spiral slag scooping structure (8), and the lever shaft (704) of the lever assembly (7) is inserted into the pitch gap between the first spiral slag scooping rib plate (802) and the second spiral slag scooping rib plate (803) under the drive of the second electric telescopic rod (702), and cooperates with the first electric telescopic rod (403) to drive the double spiral slag scooping structure (8) to move upward, and the first rotating motor (502) to drive the double spiral slag scooping structure (8) to rotate, so that the lever shaft (704) pushes the residue spiral out and drops it on the residue slide plate (9) for extraction and collection.
