DETAILED DESCRIPTION
[0021] like Figure 1-3 As shown, a ladle lining repair mechanism is operated by relying on a pit 16. A travel bracket 1 is fixed on one side of the pit 16, and a travel rod 2 is fixed on the inner side of the travel bracket 1. The lifting plate 5 moves up and down along the travel rod 2; a first lead screw 3 is rotatably provided on the inner side of the travel bracket 1; a first slider 13 is fixed to the middle of the end of the lifting plate 5, and the first slider 13 is passed through the first lead screw 3; a lifting motor 4 is fixed to the top of the travel bracket 1; and the driving shaft of the lifting motor 4 is connected to the top of the first lead screw 3. This part can control the lifting.
[0022] like Figure 2-4 As shown, a rotating motor 6 is fixed to the front end surface of the lifting plate 5, and the driving end of the rotating motor 6 is connected to one end of the rotating plate 7; a mud discharge nozzle 9 is vertically inserted and installed at the other end of the rotating plate 7; the surface of the mud discharge nozzle 9 is provided with more than one mud discharge hole 9.1, and the mud discharge holes 9.1 are arranged vertically to discharge mud toward the inner wall of the molten iron ladle 19. The driving shaft of the rotating motor 6 is located above the center of the circle of the molten iron ladle 19; the mud discharge nozzle 9 rotates along the side wall of the molten iron ladle 19 and discharges mud. The forward and reverse rotation angles of the rotating plate 7 do not exceed 200° respectively, and continuous unidirectional rotation is prohibited, otherwise the mud supply pipeline 10 will be entangled, affecting the operation of the equipment. Forward rotation once and reverse rotation once are performed alternately, which can not only complete the coating of the side wall, but also avoid the entanglement of the mud supply pipeline 10. The mud supply pipeline 10 preferably adopts a metal hose. A mud trowel 8 is fixed on one side of the mud outlet hole 9.1; the mud inlet of the mud outlet nozzle 9 is connected to the mud storage tank 12 through a mud supply pipeline 10, and a mud pump 11 is provided on the mud supply pipeline 10; the mud storage tank 12 is provided with a mud inlet, and the refractory material is stirred and mixed into a mud state and then pumped into the mud storage tank 12 through a pipeline. A pit 16 for placing a ladle 19 is opened on the ground corresponding to the mud outlet nozzle 9; a groove matching the bottom of the ladle 19 is provided on the bottom surface of the pit 16; a step is provided on one side of the pit 16 to enter the pit 16. This part controls the smearing and rotation.
[0023] like Figure 1 , 3As shown, further, in order to prevent the ladle 19 from being blocked by the mechanism when being placed, the second sliders 14 are fixed on both sides of the bottom of the travel bracket 1; the second slider 14 moves along the slide rail 17; a third slider 15 is fixed in the middle of the bottom of the travel bracket 1; the third slider 15 is inserted on the second lead screw 18; one end of the second lead screw 18 is connected to the driving end of the transfer motor 20. This part can control the overall movement of the mechanism, and it is not blocked when hoisting and placing the ladle 19. If the fixing method is not separately introduced in the above, it is welded or screwed fastened using the general technical means of technical personnel in the industry.
[0024] Here’s how it works:
[0025] First, place the molten iron ladle 19 into the groove of the pit 16 by the overhead crane, and align the water outlet of the molten iron ladle 19 with the reserved point on the pit 16; ensure that the position of the molten iron ladle 19 is accurate; then control the transfer motor 20 to drive the travel bracket 1 to move to the maximum travel position in the direction of the pit 16, and the mud discharge nozzle 9 is located above the molten iron ladle 19; control the lifting motor 4 to make the mud discharge nozzle 9 descend into the molten iron ladle 19, and start the rotating motor 6. The rotating motor 6 makes the mud discharge nozzle 9 discharge mud along the inner wall of the molten iron ladle 19. At the same time, the mud trowel 8 on the rear side scrapes the inner wall to ensure that the lining material is evenly applied.
[0026] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
