Technical Field

[0001] The utility model relates to the technical field of ladle refractory materials, in particular to a feeding device for ladle refractory materials. Background Art

[0002] Ladle refractories, such as refractory bricks, play a crucial role in the steelmaking process. These bricks must maintain structural stability in high-temperature environments, resist reaction with the molten steel, and ensure the purity of the molten steel. In actual production, the refractory bricks are first transported to a stacking device at the front of the furnace, making the feeding of refractory bricks a critical step in the production process.

Common feeding devices usually require manual placement of refractory bricks on the feeding device and arrange them neatly in advance. This method has multiple problems. First, manual placement is inefficient, affecting the work efficiency of the entire production line; second, position deviation is prone to occur during manual placement, causing refractory bricks to be misplaced during transportation, affecting subsequent stacking and firing effects. In addition, manual placement also increases the labor intensity of workers.

[0004] Therefore, a feeding device for ladle refractory material is urgently needed to solve the technical defects proposed in the above technology. Utility Model Content

[0025] Specifically, if Figure 1 、 Figure 2 and Figure 3 As shown, the device provides transmission correction of refractory bricks by setting up two sets of gantries 3 above the transmission platform 4. When the refractory bricks are transferred to the transmission roller 2, the servo motor 12 is started, and the output shaft of the servo motor 12 drives the threaded rod 14 to rotate, thereby driving the two sets of threaded blocks 13 to rotate. Since the push frame 10 is embedded in the limit groove 11 and moves back and forth, it pushes the push plate 8 to relatively clamp multiple groups of refractory bricks from both ends, and correct the position of the placed refractory bricks so that they can be placed regularly and transmitted to the furnace body.

[0026] Embodiment 2: Multiple groups of transmission rollers 2 are evenly assembled inside the transmission platform 4. A variable speed motor 1 is installed on the left side of the rear end of the transmission platform 4. A transmission sprocket and a transmission chain belt 6 are installed on the shaft ends between the output shaft of the variable speed motor 1 and the transmission rollers 2, and between the multiple groups of transmission rollers 2.

Since the push frame 10 is embedded in the limit groove 11 and moves back and forth, it pushes the push plate 8 to clamp multiple groups of refractory bricks from both ends, and correct the position of the placed refractory bricks so that they can be placed regularly and transmitted to the furnace body. The bottom end of the transmission platform 4 adopts a liftable design. By setting a right bracket 18 with an "X" structure on the right side of the bottom end of the transmission platform 4, when the transmission platform 4 needs to adapt to furnace bodies of different heights, the cylinder 22 can be started, and the piston rod pulls the distance adjustment rod 17 to move back and forth, thereby adjusting the support angle of the right bracket 18, thereby realizing the height adjustment of the right side of the transmission platform 4, that is, the feed side, to facilitate tilted feeding.
