[0039] Example 1: Reference Figure 1-Figure 8A slag removal device for a continuous casting and rolling production line for copper rod production comprises a mobile frame 1, one end of the mobile frame 1 is connected to a mechanical arm 11, the mobile frame 1 is arranged above a ladle 9, a fixed cylinder 2 and a rotating rod 4 are arranged below the mobile frame 1; a fixed rod 21 is installed between the top of the fixed cylinder 2 and the mobile frame 1, and both sides of the circumferential outer wall of the fixed cylinder 2 are installed with a filter hopper 3, the top and one side of the filter hopper 3 are opened, and the bottom and one side of the filter hopper 3 are opened. The opening of one side of the filter hopper 3 is set to an opening surface, and the filter hopper 3 is away from one side. The outer wall of the side opening is set as a back surface, and the cross-section of the filter hopper 3 is set as a fan-shaped structure; the top of the rotating rod 4 is rotatably connected to the mobile frame 1, and the top of the rotating rod 4 is transmission-connected to the motor 6. Slag scraping plates 5 are installed on both sides of the circumferential outer wall of the rotating rod 4, and the motor 6 is fixed to the top of the mobile frame 1; during the slag scraping operation, the slag scraping plate 5 starts to rotate from the outer wall position of one of the filter hoppers 3 away from the one side opening, and rotates to the outer wall position of the one side opening of the other filter hopper 3; during the slag scraping operation, the initial positions of the filter hopper 3 and the slag scraping plate 5 are as follows Figure 3 As shown, two slag-scraping plates 5 are respectively attached to the back surfaces of two different slag-scraping buckets 3, and then the fixed cylinder 2, the slag-scraping bucket 3, the rotating rod 4 and the slag-scraping plates 5 are lowered into the ladle 9 by the mechanical arm 11 and the mobile frame 1, and the bottom of the slag-scraping bucket 3 is below the liquid surface;

[0040] Then the motor 6 is used to rotate the rotating rod 4 and the scraping plate 5. Figure 4 As shown, the bottom end of the scraper plate 5 is located below the liquid surface, and the top end of the scraper plate 5 is located above the liquid surface. During the rotation of the scraper plate 5, the impurities suspended in the liquid surface and a short distance below the liquid surface are driven toward the filter hopper 3;

[0041] Until the scraping plate 5 rotates to fit the opening surface of the two filter hoppers 3, Figure 5 As shown, the impurities around the liquid surface are gathered between the filter slag bucket 3 and the scraper plate 5, and then the filter slag bucket 3 and the scraper plate 5 are lifted upward by the movable frame 1 to clear the impurities;

[0042] In the process of the slag scraping plates 5 on both sides being fitted with the slag bucket 3 and rotating to be fitted with the other slag bucket 3, the impurities around the liquid surface can be completely gathered and confined within the closing range of the slag bucket 3 and the slag scraping plates 5, so that the impurities around the liquid surface can be effectively and completely cleared out during the lifting process, avoiding the need for multiple slag scraping and improving the slag scraping effect. The rotation of the slag scraping plates 5 can disperse the impurities at the center of the ladle to the periphery, and avoid the impurities in the middle position being relatively static and difficult to clear out. The rotation of the slag scraping plates 5 can generate centrifugal force around the liquid surface, so that the impurities suspended below the liquid surface can rotate centrifugally and rise and be collected around the slag bucket 3, thereby further improving the effect of slag scraping and clearing impurities and improving the slag scraping efficiency.

[0043] In the present invention, reference is made to Figure 1-Figure 8 The bottom end of the filter hopper 3 is arranged to be an inclined surface, and the bottom end of the filter hopper 3 is inclined upward toward the direction close to the opening on one side, so that in the process of placing the filter hopper 3 and the slag plate 5 downward into the ladle 9, the inclined surface of the bottom of the filter hopper 3 is used to make the impurities around the liquid surface and located below the filter hopper 3 move along the liquid surface toward the opening surface of the filter hopper 3, so as to improve the slag cleaning effect of the impurities. The top end of the slag plate 5 is located above the top end of the filter hopper 3, and the bottom end of the slag plate 5 is located below the bottom end of the filter hopper 3, so that in the process of rotating the slag plate 5 to scrape the impurities, the liquid flow can be driven to lead the impurities below the filter hopper 3 upward for cleaning, thereby improving the completeness of the slag scraping and the efficiency of the cleaning operation.

[0044] In the present invention, reference is made to Figure 1-Figure 8 The slag scraping plate 5 is provided with a sleeve plate 1 51 and a sleeve plate 2 52 of heat insulating material. The sleeve plate 1 51 is fixed to the outer wall of the rotating rod 4. A sliding cavity is opened at the end of the sleeve plate 1 51 away from the rotating rod 4. The sleeve plate 2 52 is sealingly and slidingly connected to the inner wall of the sliding cavity. The sleeve plate 2 52 is connected to the inner wall of the sliding cavity with a spring, so that the telescopic effect of the slag scraping plate 5 is achieved by the sleeve plates 1 51 and the sleeve plates 2 52, so that when the inner wall of the ladle is in an irregular shape, the filter hopper 3 stays in the adapted position and the slag scraping plate 5 is rotated, and the telescopic performance of the slag scraping plate 5 is used to completely scrape and gather impurities to the position of the filter hopper 3, thereby further improving the completeness of the slag scraping and the efficiency of the slag scraping operation.

[0045] In the present invention, reference is made to Figure 1-Figure 8 The rotating rod 4 is rotatably connected to the inner wall of the fixed cylinder 2, and a slide groove 511 is provided at the end of the sleeve plate 51 corresponding to the fixed cylinder 2. The slide groove 511 is in sliding contact with the outer wall of the fixed cylinder 2, so as to cover the liquid surface as much as possible and reduce the missing area at the center position, so as to further improve the slag removal operation effect.

[0046] In the present invention, reference is made to Figure 1-Figure 8 A plurality of horizontally distributed guide blocks 512 are fixed to the bottom of the outer wall of the sleeve plate 51 which is open on one side of the filter slag bucket 3. The guide blocks 512 are distributed below the filter slag bucket 3, and the thickness of the guide blocks 512 gradually increases from bottom to top, so that the outer wall of the guide blocks 512 has an inclined structure, so that during the rotation of the scraping plate 5, the guide blocks 512 are used to improve the upward and outward movement effect of the liquid flow below the filter slag bucket 3, so as to guide the impurities pressed into the bottom upward and outward, thereby improving the scraping and cleaning effect; the width of the guide blocks 512 gradually increases from bottom to top, so that the gap between two adjacent guide blocks 512 gradually decreases from bottom to top, so as to improve the upward vertical flow effect of the liquid flow during the rotation of the scraping plate 5, and further improve the aggregation and cleaning effect of the impurities.

[0047] In the present invention, reference is made to Figure 1-Figure 8A plurality of guide grooves 513 are provided on the outer wall of the sleeve plate 51 which is open toward one side of the filter residue bucket 3. The guide grooves 513 correspond to the positions of the filter residue bucket 3. The guide grooves 513 are inclined upward in a direction away from the rotating rod 4, so as to further guide the impurities suspended in the liquid toward the outside and upward to avoid sinking to the bottom of the filter residue bucket 3. The depth of the guide grooves 513 gradually increases from bottom to top, so as to guide the impurities upward and gather them at the deep end of the top of the guide grooves 513, so as to avoid the impurities from flowing back with the liquid and enhancing the cleaning effect of the scraping.

[0048] Embodiment 2: Embodiment 2 includes all structures and methods of Embodiment 1, with reference to Figure 1-Figure 10 , a slag removal device for a continuous casting and rolling production line for copper rod production. On the basis of Example 1, a slag filter bucket 3 is provided with a filter plate 1 31 fixed to the outer wall of a fixed cylinder 2, the filter plate 1 31 is placed vertically, and a horizontally placed filter plate 2 32 is fixed to the bottom of the filter plate 1 31. The filter plate 2 32 is arranged in a fan shape, and a baffle 33 is provided on the filter plate 2 32 at a position away from the fixed cylinder 2. The thickness of the baffle 33 gradually decreases in the direction away from the filter plate 1 31, so that the impurities driven by the slag removal plate 5 are conveniently gathered in the slag filter bucket 3 along the direction of the baffle 33.

[0049] In the present invention, reference is made to Figure 1-Figure 10 The position where the filter hopper 3 is in contact with the filter hopper 3 is a horizontal position, and the electric guide rail 7 is arranged in parallel with the filter plate 31. The electric guide rail 7 is connected with an extension rod 81 extending vertically downward. For ladles 9 with different inner diameters or ladles 9 with irregular shapes, the extension rod 81 can be moved from the inside of the filter hopper 3 to the outside through the electric guide rail 7, so that the extension rod 81 pushes the baffle plate 33 outward to be close to the inner wall of the ladle to expand the opening area of ​​the filter hopper 3. When the filter hopper 3 and the slag plate 5 are lifted upward, the extension rod 81 is moved away from the baffle plate 33, and the baffle plate 33 is rotated and reset to gather impurities and block the bottom, thereby ensuring the gathering and cleaning effect of impurities and further improving the slag removal effect and slag removal efficiency.

[0050] In the present invention, reference is made to Figure 1-Figure 10A through slot 12 is provided on the side of the mobile frame 1 located on the electric guide rail 7, and a mounting frame 71 is connected to the electric guide rail 7. A vertical electric telescopic rod 8 is fixed on the mounting frame 71, and the electric telescopic rod 8 is connected to the top of the extension rod 81. A through hole is provided on the mounting frame 71 for sliding contact with the extension rod 81, so that when the electric guide rail 7 is used to realize the movement of the extension rod 81 to adjust the opening of the filter slag bucket 3, when the filter slag bucket 3 is lowered into the ladle 9 and the slag scraping plate 5 is rotated during the slag scraping operation, the extension rod 81 is alternately hit against the filter plate 2 32 through the electric telescopic rod 8 to prevent impurities from being attached to the bottom end of the filter slag bucket 3 and being pressed down, thereby further improving the slag scraping operation effect through the vertical movement of the extension rod 81 and the rotation of the slag scraping plate 5.
