[0022] like Figure 4 As shown, a vent 301 is provided on one side of the bottom of the storage box 3. A movable frame 302 is slidably fitted onto the inner wall of the storage box 3. Multiple springs 303 are fixedly connected to the bottom of the movable frame 302, and the other end of each spring 303 is fixedly connected to the inner wall of the storage box 3. An inclined block 304 is fixedly connected to the middle of the movable frame 302, and the inclined block 304 is in slidable contact with the movable frame 2. A transmission rack 305 is fixedly connected to the movable frame 302. The springs 303 enable the movable frame 302 to automatically reset.

[0023] like Figure 5 As shown, a rotating shaft 401 is fixedly connected to one end of the cover plate 4. The rotating shaft 401 is rotatably connected to the inner wall of the storage box 3. A drive wheel 402 is fixedly connected to the outer wall of the middle part of the rotating shaft 401. A universal joint A403 is fixedly connected to the other end of the rotating shaft 401. The universal joint A403 is rotatably connected to the inner wall of the storage box 3. An opening and closing wheel 404 is fixedly connected to the other end of the universal joint A403. The opening and closing wheel 404 is engaged with the transmission rack 305 for transmission.

[0024] like Figure 6 As shown, a groove 501 is provided on one side of the fixed frame 5. Rubber wheels 502 are rotatably connected to both ends of the fixed frame 5. The rubber wheels 502 are in frictional contact with the outer wall of the lower guide roller 1. A gear A503 is fixedly connected to one side of the rubber wheel 502. A transmission wheel 504 is meshed on one side of the gear A503 and is rotatably connected to the fixed frame 5. The rubber wheels 502 drive the lower guide roller 1 to rotate, achieving a comprehensive cleaning effect.

[0025] like Figure 7As shown, the jet mechanism 6 includes an impeller seat 601. The input end of the impeller seat 601 extends through the inner wall of the storage box 3 to the outside and is fixedly connected to an air pump 602. The air pump 602 is fixedly connected to the storage box 3. The output end of the impeller seat 601 is fixedly connected to a jet pipe 603. The jet pipe 603 is fixedly connected to a fixed frame 5. A straight jet groove is opened at the bottom end of the jet pipe 603. An impeller 604 is rotatably connected to the inner wall of the impeller seat 601. Both ends of the impeller 604 extend through the inner wall of the impeller seat 601 to the outside. Gears B605 are fixedly connected to both ends of the impeller 604. Gears B605 mesh with transmission wheels 504 for transmission. Universal joints B606 are fixedly connected to both ends of the impeller 604. Universal joints B606 are rotatably connected to the fixed frame 5. An L-shaped rod 607 is fixedly connected to the other end of the universal joint B606. High-pressure air is injected into the impeller seat 601 using air pump 602. At this time, the high-pressure air will be ejected through the jet pipe 603, and the high-pressure air will drive the impeller 604 to rotate, so that the impeller 604 can drive the connected gear B605 to rotate. At this time, the gear B605 will drive the transmission wheel 504 to rotate, so that the transmission wheel 504 can drive the gear A503 to rotate, so that the gear A503 can drive the connected rubber wheel 502 to rotate, so that the rubber wheel 502 can drive the contacting lower guide roller 1 to rotate.

[0026] like Figure 8 As shown, a brush plate 701 is fixedly connected to one side of the guide roller maintenance frame 7. The brush plate 701 is in sliding contact with the outer wall of the lower guide roller 1. A slider 702 is fixedly connected to the guide roller maintenance frame 7. The slider 702 is in sliding cooperation with the inner wall of the groove 501. An open plate 703 is fixedly connected to both ends of the guide roller maintenance frame 7.

[0027] By setting up the jetting mechanism 6 and the guide roller maintenance frame 7, when the lower guide roller 1 is not in use, high-pressure air is sprayed out by the jetting pipe 603. At the same time, the jetting mechanism 6 drives the swing frame 8 to swing back and forth, thereby driving the guide roller maintenance frame 7 to move back and forth. This allows the brush plate 701 at the bottom to work in conjunction with the high-pressure air to effectively treat the aluminum alloy slag adhering to the surface of the lower guide roller 1. During the use of the lower guide roller 1 in the light pressure of the thick slab continuous casting machine, the surface cleaning efficiency of the lower guide roller 1 is improved, the amount of manual cleaning is reduced, the service life of the lower guide roller 1 is extended, the risk of wear and corrosion is reduced, the quality of the cast billet is guaranteed, the qualified rate of the cast billet is improved, and the production efficiency and automation level are effectively improved.

[0028] like Figure 8As shown, the swing frame 8 has a transmission groove 801. The inner wall of the transmission groove 801 is slidably fitted with the outer wall of one end of the L-shaped rod 607. A transmission head 802 is fixedly connected to the bottom end of the swing frame 8, and the transmission head 802 is slidably fitted with the inner wall of the opening plate 703. The end of the swing frame 8 near the transmission head 802 is rotatably connected to the inner wall of the storage box 3, so that when the swing frame 8 swings, lever transmission is realized, making it easier to move the guide roller maintenance frame 7.

[0029] like Figure 9 As shown, a receiving cylinder 901 is placed on one side of the bottom of the impurity seat 9, and a filter tube 902 is rotatably connected to the middle of the impurity seat 9. One end of the filter tube 902 extends to the inner wall of the storage box 3 through a pin and is fixedly connected to a driven wheel 903. The driven wheel 903 is meshed with the driving wheel 402 for transmission.

[0030] Working principle: When the lower guide roller 1 is not in use, the hydraulic rod 201 drives the movable frame 2 to move, so that the movable frame 2 drives the lower guide roller 1 to retract into the storage box 3. When the lower guide roller 1 is completely retracted into the storage box 3, as the movable frame 2 continues to move, it will contact and squeeze the inclined block 304, so that the inclined block 304 can drive the connected movable frame 302 to move. At this time, the movable frame 302 will drive the transmission rack 305 to move. The transmission rack 305 will drive the opening and closing wheel 404 to rotate, which will cause the opening and closing wheel 404 to drive the connected universal joint A403 to rotate, which will cause the universal joint A403 to drive the cover plate 4 connected to the rotating shaft 401 to close automatically. While the rotating shaft 401 drives the cover plate 4 to close, the driving wheel 402 on the rotating shaft 401 will drive the filter tube 902 connected to the driven wheel 903 to rotate, so that the filter tube 902 rotates from above the receiving cylinder 901 to the exhaust port 301. Then, high-pressure air is injected into the impeller seat 601 using the air pump 602. At this time, the high-pressure air will be ejected through the jet pipe 603. Simultaneously, the high-pressure air will drive the impeller 604 to rotate, so that the impeller 604 can drive the connected gear B605 to rotate. At this time, the gear B605 will drive the transmission wheel 504 to rotate, so that the transmission wheel 504 can drive the gear A503 to rotate, so that the gear A503 can drive the connected rubber wheel 502 to rotate, so that the rubber wheel 502 can drive the contacting lower guide roller 1 to rotate. Then, when the impeller 604 rotates, it will drive the universal joints B606 at both ends to rotate, so that the universal joints B606 can drive the connected L-shaped rod 607 to rotate. At this time, the other end of the L-shaped rod 607 will slide in the transmission groove 801 on the swing frame 8, which will drive the swing frame 8 to swing, so that the transmission head 802 at the other end of the swing frame 8 will slide in the opening on the opening plate 703. At this time, the slider 702 on the guide roller maintenance frame 7 will slide in the sliding groove 501, so that the opening plate 703 drives the brush plate 701 on the guide roller maintenance frame 7 to reciprocate, and treat the aluminum alloy slag on the surface of the lower guide roller 1. The treated aluminum alloy slag will be discharged through the exhaust port 301 and filtered through the filter tube 902.
