A chamfer is provided at the edge of the transmission plate 19;During use, initially, the docking groove at the bottom of the placement plate 13 is aligned with the transmission plate 19, but the transmission plate 19 is not yet abutted in the docking groove. When firing high-alumina bricks, the furnace door 4 is opened. By starting the pushing motor 5, the pushing motor 5 drives the transmission lead screw 9 to rotate, causing the transmission lead screw 9 to push the connecting plate 7 forward through the transmission sleeve 10. The connecting plate 7 then drives the rollers 8 to roll forward on the slide rail 6. The connecting plate 7 drives the sliding support plate 11 and the placement plate 13 to move to the furnace mouth. Then, the sliding support plate 11 is slid forward from the connecting plate 7, enabling the sliding support plate 11 to extend out of the furnace mouth. After placing the high-alumina bricks to be fired on the sliding support plate 11, the sliding support plate 11 is pushed back onto the connecting plate 7, and by rotating the placement plate 13, the marking line on the placement plate 13 is made to coincide with the marking line at the front end of the sliding support plate 11. The furnace door 4 is closed, and then by the reverse rotation of the pushing motor 5, the pushing motor 5 pulls the connecting plate 7 back into the furnace body 1. When the transmission sleeve 10 is fully retracted, the marking lines on the placement plate 13 and the sliding support plate 11 coincide, and the docking groove at the bottom of the placement plate 13 is realigned with the transmission plate 19. By starting the lifting cylinder 15, the lifting cylinder 15 pushes the lifting plate 16 upward.

By providing the support bars 20, sufficient gaps can be left at the bottom of the high-alumina bricks when placing them, facilitating the hot air flow to pass through the bottom and further improving the drying effect of the high-alumina bricks.

[0026] A handle 23 is fixedly connected to the front end of the sliding pallet 11; by providing the handle 23, it is possible to make the removal and replacement of the sliding pallet 11 more convenient.

[0027] Limit plates 24 are fixedly connected to the front ends of both groups of the slide rails 6; by providing the limit plates 24, it is possible to effectively prevent the connecting plate 7 from disengaging the rollers 8 from the slide rails 6 when moving forward, playing a limiting role.

[0028] Four groups of anti-slip rubber pads 25 are symmetrically and fixedly connected to the bottom end of the bottom plate 3; by providing the anti-slip rubber pads 25, it is possible to effectively prevent the bottom plate 3 from slipping when placed on the ground.

[0029] For a kiln for firing high-alumina bricks of the present utility model, its working principle is as follows. When in use, initially, the docking groove at the bottom of the placement plate 13 is aligned with the drive plate 19, but the drive plate 19 is not yet abutted in the docking groove. When firing high-alumina bricks, the furnace door 4 is opened. By starting the pushing motor 5, the pushing motor 5 drives the transmission screw rod 9 to rotate, so that the transmission screw rod 9 pushes the connecting plate 7 forward through the transmission sleeve 10. The connecting plate 7 drives the rollers 8 to roll forward on the slide rails 6. The connecting plate 7 drives the sliding pallet 11 and the placement plate 13 to move to the kiln opening. Then, the sliding pallet 11 is slid forward from the connecting plate 7, so that the sliding pallet 11 extends out of the kiln opening. After placing the high-alumina bricks to be fired on the sliding pallet 11, the sliding pallet 11 is pushed back onto the connecting plate 7, and by rotating the placement plate 13, the marking line on the placement plate 13 is made to coincide with the marking line at the front end of the sliding pallet 11. The furnace door 4 is closed, and then by the reverse rotation of the pushing motor 5, the pushing motor 5 pulls the connecting plate 7 back into the kiln body 1 again. When the transmission sleeve 10 is completely retracted, the marking lines on the placement plate 13 and the sliding pallet 11 coincide, and the docking groove at the bottom of the placement plate 13 is aligned with the drive plate 19 again. By starting the lifting cylinder 15, the lifting cylinder 15 pushes the lifting plate 16 upward. The lifting plate 16 drives the rotating motor 17 upward. The rotating motor 17 then pushes the drive shaft 18 upward to slide, so that the drive shaft 18 pushes the drive plate 19 upward, thereby making the drive plate 19 abut into the docking groove at the bottom of the placement plate 13. By starting the rotating motor 17, the rotating motor 17 drives the drive shaft 18 to rotate. The drive shaft 18 drives the placement plate 13 to rotate on the annular support 12 through the cooperation of the drive plate 19 and the docking groove. By the rotation of the placement plate 13, the high-alumina bricks are evenly heated and dried. After the drying is completed, the lifting cylinder 15 drives the lifting plate 16 to move downward, so that the drive plate 19 disengages from the docking groove, and then the connecting plate 7 can be pushed to the kiln opening to wait for taking the high-alumina bricks.
