[0001] The utility model relates to the technical field of mineral resource smelting equipment, in particular to a ladle waste heat docking device. Background Art

[0002] The ladle is a casting equipment for casting. It is used for casting operations in the foundry workshop. It receives molten iron in front of the furnace and then transports it to the mold for casting by a crane. The casting material of the ladle 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. After repeated use, the lining is damaged by high temperature and needs to be re-applied regularly. The repaired lining needs to be dried again before it can be put into use.

[0003] Natural air drying takes too long, and the ladle cannot be put into use quickly, resulting in the need to purchase a large number of ladles in the factory to ensure normal production. In order to ensure the drying efficiency of the lining, it was found during use that the temperature of the ladle that had just been used was high. This part of the heat source can be used to dry the repaired ladle, but due to the high temperature of the ladle, it is necessary to operate the ladle through equipment. Therefore, according to the above scheme, a method is designed that can buckle the ladle with residual heat on the ladle to be dried, so that the heat is transferred to the repaired ladle, thereby increasing the drying speed of the lining.

DETAILED DESCRIPTION

[0022] As shown in the figure, a ladle waste heat docking device, the adjustment of which is divided into three parts: longitudinal adjustment, transverse adjustment and rotation adjustment. In the transverse adjustment part: the outer beam 1 is a frame-like structure with an opening at the bottom; a transverse travel rail 3 is fixed at both ends of the bottom of the outer beam 1; a first lead screw 7 is rotatably arranged in the transverse travel rail 3; a first slider 9 is fixed at the bottom of the longitudinal travel rail 2; the first slider 9 is inserted on the first lead screw 7 and moves along the slide groove of the transverse travel rail 3; one end of the first lead screw 7 is connected to the driving end of the transverse drive motor 6; the transverse travel rail 3 provides the clamp 13 with a travel displacement space for opening and closing.

[0023] As shown in the figure, the longitudinal adjustment part: a second lead screw 8 is rotatably provided in the slide groove of the longitudinal travel rail 2; a second slider 10 is fixed to one side of the moving block 11; the second slider 10 is passed through the second lead screw 8 and moves along the slide groove of the longitudinal travel rail 2; one end of the second lead screw 8 is connected to the driving end of the longitudinal drive motor 5; the longitudinal adjustment part mainly provides a lifting function for the clamp 13.

[0024] As shown in the figure, the rotation adjustment part: the middle part of the moving block 11 is rotatably provided with a rotating rod 12; the opposite end of the rotating rod 12 is fixed with a clamp 13; the other end of the rotating rod 12 is connected to the driving end of the rotating motor 4. The inside of the clamp 13 is an arc-shaped structure that fits the ladle 14. A pit 21 is provided on the ground surface, and the ladle 14 to be repaired is placed in the pit 21, and the height of the ladle 14 to be repaired is flush with the ground; a step is provided on one side of the pit 21 to enter the pit 21 and check the ladle 14.

[0025] As shown in the figure, a movable base 15 is provided below the clamp 13, and a walking wheel 22 is provided at the bottom of the movable base 15; a circular hole 15.1 is opened in the middle of the plate surface of the movable base 15; a docking collar 16 is movably provided in the circular hole 15.1; brackets are fixed on both sides of the circular hole 15.1; a collar cylinder 17 is vertically fixed on the bracket; the telescopic end of the collar cylinder 17 passes through the plate surface and is connected to the side wall of the docking collar 16, driving the docking collar 16 to move up and down. The outer diameter of the docking collar 16 is smaller than the inner diameter of the iron ladle 14; the docking collar 16 and the telescopic end of the collar cylinder 17 are fixed by a connector 18. The function of the docking collar 16 is mainly to connect the two iron ladles 14. Since one of the iron ladles 14 can move on the movable base 15, there is a gap at the open part of the two iron ladles 14, and the heat loss is serious. After the docking is completed by the docking collar 16, the utilization rate of the heat of the iron ladle 14 is improved. Furthermore, the surface of the mobile base 15 is provided with a matching nested protrusion 19 corresponding to the liquid outlet of the molten iron ladle 14, which blocks the upper gap of the molten iron ladle 14 from losing temperature, ensuring that the temperature is transferred through the molten iron ladle 14 to be dried before dissipating. The bottom of the transverse travel rail 3 is provided with a support leg 20, and a running wheel 22 is provided under the support leg 20; the running wheel 22 is driven by a motor. The bottom of the mobile base 15 is also provided with a running wheel 22, and the running wheel 22 has the same structure as the running wheel 22 at the bottom of the transverse travel rail 3. The running wheels 22 at the two positions adopt the existing motor direct drive method, which will not be repeated. The running wheel 22 of the mobile base 15 and the running wheel 22 at the bottom of the transverse travel rail 3 move along their respective corresponding tracks 23. If the fixing method is not separately introduced in the above, they are all welded or threaded fastened using the general technical means of technical personnel in the industry.

[0026] Here’s how it works:

[0027] After the overhead crane places the used ladle 14 at the designated position, the traveling wheel 22 at the bottom of the horizontal travel rail 3 drives the device to move, the clamp 13 moves to the position of the ladle 14 and clamps it, and then rises through the longitudinal travel rail 2. After rising, the motor 4 is turned to control the rotating rod 12 to drive the clamp 13 to rotate 180°, so that the ladle 14 is turned over, the opening of the ladle 14 is facing downward, and then placed above the circular hole 15.1 of the mobile base 15, so that the upper end opening of the docking collar 16 is nested with the opening of the ladle 14. After the mobile base 15 moves to the top of the ladle 14 to be dried, the collar cylinder 17 extends, so that the bottom of the docking collar 16 is docked with the opening of the ladle 14 to be dried, and the top of the docking collar 16 does not break away from the matching state with another ladle 14, so that the ladle 14 is docked and connected. The drying time is set according to the heating time.

[0028] 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.
