DETAILED DESCRIPTION OF THE EMBODIMENTS

[0015] The technical solutions of the present application will be further described and illustrated below in conjunction with the drawings and embodiments.

[0016] Such as Figure 1-2As shown in the figure, there is a melting furnace for facilitating the removal of scum, which includes a platform 1. A column 2 is arranged at the center of the platform 1. A turntable 3 is rotatably connected to the column 2. A first cylinder 4 vertically downward is arranged on one side of the center of the turntable 3. The free end of the piston rod of the first cylinder 4 is connected to a connecting seat 5. A second cylinder 6 vertically downward is arranged on the upper surface of the connecting seat 5. The lower end of the connecting seat 5 is fixedly connected with a slag removal assembly. The slag removal assembly includes an outer filter frame 7. An inner filter frame 8 is slidably connected to the inner side of the outer filter frame 7. A guide rod 9 is arranged at the center of the inner filter frame 8. The upper end of the guide rod 9 passes through the outer filter frame 7 and is axially connected to the free end of the piston rod of the second cylinder 6. A furnace body 10 is arranged on the platform 1 below the slag removal assembly. A waste bin 11 for placing residues is arranged on the platform 1 on the other side of the furnace body 10. The outer filter frame 7 includes a frame body 701 with a U-shaped cross-section. A plurality of gaps 702 for the molten aluminum to pass through are spacedly arranged on the side surface of the frame body 701. A chute 703 is arranged on the inner wall of the frame body 701. A limiting protrusion 704 is arranged at the bottom of the chute 703. The inner filter frame 8 includes a bottom plate 801. A plurality of vertical rods 802 are arranged at the edge of the bottom plate 801. Sliders 803 slidably connected to the chute 703 are arranged on the outer side surfaces of the vertical rods 802. A plurality of fine holes 804 are arranged on the bottom plate 801. The connecting seat 5 includes a connecting plate 501. A vertical connecting column 502 is arranged on the upper surface of the connecting plate 501. The upper end of the connecting column 502 is connected to the piston rod of the first cylinder 4. A pull rod is inserted through the connecting plate 501 inside the connecting column 502. The lower end of the pull rod is fixedly connected to the upper end of the outer filter frame 7. An installation seat 12 is fixedly connected to the column 2. A speed reducer 13 is arranged on the installation seat 12.

[0017] During operation, the operator controls the first cylinder 4 to work. During the vertical downward movement of the piston rod of the first cylinder 4, the connecting seat 5 and the entire slag skimming assembly move downward synchronously with the piston rod until the outer filtration frame 7 starts to enter the furnace body 10. At the same time, the operator controls the second cylinder 6 to work, and the piston rod of the second cylinder 6 drives the inner filtration frame 8 to move downward, so that the relative movement between the outer filtration frame 7 and the inner filtration frame 8 generates an annular liquid inlet space, allowing the molten aluminum and floating impurities to enter the slag skimming assembly together. After completion, the operator controls the piston rod of the second cylinder 6 to move vertically upward to move the inner filtration frame 8 upward to close the liquid inlet space. The molten aluminum in the slag skimming assembly flows back into the furnace body 10 through the gap 702 on the side of the outer filtration frame 7 and the fine holes 804 on the bottom plate 801 of the inner filtration frame 8, while the floating slag remains in the slag skimming assembly. After completion, the entire turntable 3 is rotated by the speed reducer 13 to rotate the slag skimming assembly above the waste box 11, and then the second cylinder 6 is controlled to separate the inner filtration frame 8 from the outer filtration frame 7, and the operator cleans the internal floating slag into the waste box 11.
