[0002] The ladle is a commonly used pouring equipment in casting. It is used for casting operations in the foundry workshop, receiving molten iron in front of the furnace, and then transported to the casting mold by a crane for pouring. The lining material for the ladle castable in the foundry should be selected according to the working conditions. The lining material applied to the inner wall of the ladle can increase the service life. It is suitable for the overall lining of the ladle of small and medium-sized foundries and is the choice of refractory materials for the ladle.

[0003] After repeated use, the traditional lining is damaged by high temperature and needs to be repaired regularly for subsequent use. Before repairing, the operator needs to enter the ladle to shovel up the damaged lining material and then re-apply it. Although the ladle is in a non-operating state, there are safety hazards.

DETAILED DESCRIPTION

[0020] like Figure 1-3 As shown, a ladle lining removal device is provided, which carries a ladle 20 through a mobile base 1. The ladle 20 to be cleaned is placed on the surface of the mobile base 1. In order to ensure the accurate position, a circular groove 15 for placing the ladle 20 is provided on the surface of the mobile base 1. The running wheel 17 at the bottom of the mobile base 1 moves along the track 18. The running wheel 17 is controlled by the existing motor drive mode and moves to the end of the track 18 to reach the designated area. The two ends of the track 18 are provided with a stopper 19. When the mobile base 1 reaches the designated position, the stopper 19 on one side blocks the mobile base 1 from moving forward. The mobile base 1 moves to the inner side of the lifting frame 2; the lifting frame 2 is provided with a slide groove 2.1; the slide groove 2.1 is movably provided with a lead screw 5; the slider 4 is inserted on the lead screw 5 and moves up and down along the slide groove 2.1; the top of the lead screw 5 is connected to the driving end of the first drive motor 6; and the sliders 4 are connected and fixed with a crossbeam 3. The middle part of the crossbeam 3 is fixed with a second drive motor 7; and the cover barrel 13 is fixed below the crossbeam 3. The diameter of the cover barrel 13 is larger than the diameter of the ladle 20; the cover barrel 13 is provided with a matching nesting notch 13.1 corresponding to the lug and the outlet of the ladle 20. When cleaning, the cover barrel 13 needs to be adjusted to fall by the lead screw 5 to cover the outside of the ladle 20.

[0021] like Figure 2-4 As shown, the driving end of the second driving motor 7 is connected to one end of the driving long shaft 8; the driving long shaft 8 penetrates into the cover barrel 13 and is driven to rotate by the second driving motor 7. Specifically, the top of the cover barrel 13 is connected and fixed with the cross beam 3 through the square cavity 16; the driving long shaft 8 passes through the square cavity 16 and enters the cover barrel 13. While the square cavity 16 connects and fixes the cross beam 3 with the cover barrel 13, the square cavity 16 provides a cavity for the shaft body to rotate, and the driving long shaft 8 is prevented from being exposed to the outside. A first blade disc 12 is fixed at the bottom of the driving long shaft 8; one end of the connecting cross plate 9 is fixed to the driving long shaft 8; a blade plate 11 is movably provided below the other end of the connecting cross plate 9; the blade plate 11 is in a cross shape, a shaft body is fixed in the middle of the blade plate 11, a third drive motor 10 is fixed at the position corresponding to the shaft body on the surface of the connecting cross plate 9, and the driving end of the third drive motor 10 is connected to the shaft body to drive the blade plate 11 to rotate; the connecting cross plate 9 is located in the cover barrel 13, and the connecting cross plate 9 drives one end of the connecting cross plate 9 to rotate along the inner wall of the molten iron ladle 20 through the second drive motor 7. During the rotation process, the blade plate 11 is scraped and cleaned by the rotation of the third drive motor 10 itself. A second blade disc 14 that rotates synchronously is fixed at the bottom of the blade plate 11; the first blade disc 12 and the second blade disc 14 are disc-shaped structures, and blades for scraping the bottom of the molten iron ladle 20 are fixed at the bottom of the first blade disc 12 and the second blade disc 14; the diameter of the first blade disc 12 is larger than that of the second blade disc 14. During the rotation process, the first cutter disc 12 and the second cutter disc 14 can cover the bottom area of ​​the ladle 20. The second cutter disc 14 rotates with the end connected to the horizontal plate 9 as the center of the circle while the third drive motor 10 rotates, so that the cutter plate 11 can move and clean along the inner wall of the ladle 20. If the fixing method is not separately introduced in the above, it is welded or screwed fastened using the common technical means of technicians in the industry.

[0022] Here’s how it works:

[0023] The molten iron ladle 20 is placed in the circular groove 15 by the overhead crane, and the movable base 1 is moved to the designated position. The first drive motor 6 is started to move the cover barrel 13 downward; after the cover barrel 13 is covered, the second drive motor 7 and the third drive motor 10 are controlled to be powered on and start working, and the blade 11 and the cutter disc start to rotate. The blade 11 is driven by the driving shaft 8 to rotate one circle to complete the cleaning of the inner wall of the molten iron ladle 20. During the rotation of the blade 11, the second cutter disc 14 also rotates one circle. The first cutter disc 12 and the second cutter disc 14 rotate to complete the bottom cleaning. After the cleaning is completed, the equipment is reset.
