[0047] The upper shaft disc 20 is assembled on the upper cover 10. The upper cover 10 and the upper shaft disc 20 are annular structures. A first shaft disc groove 21 is arranged on the annular structure of the upper shaft disc 20. One end of the first shaft disc groove 21 faces the inner ring direction of the upper shaft disc 20, and the other end of the first shaft disc groove 21 faces the outer ring direction of the first shaft disc groove 21.

[0048] The lower shaft disc 40 is arranged on the lower cover 50, the upper cover 10 and the lower shaft disc 40 are annular structures, and a second shaft disc groove 41 is arranged on the annular structure of the lower shaft disc 40, one end of the second shaft disc groove 41 faces the inner ring direction of the upper shaft disc 20, and the other end of the second shaft disc groove 41 faces the outer ring direction of the first shaft disc groove 21, and the first shaft disc groove 21 and the second shaft disc groove 41 are staggered on the projection surface of the disc surface direction.

[0049] The handle 60 is connected to the lower shaft disc 40;

[0050] The sealing claw 30 is arranged around the center of the annular structure of the upper shaft disc 20 and the lower shaft disc 40, and includes a shaft disc contact surface 31, an opening and closing guide surface 32, a rotating shaft 33 and a guiding member 34. The rotating shaft 33 is connected to the shaft disc contact surface 31, and is plugged into the first shaft disc groove 21 and the second shaft disc groove 41 through the rotating shaft 33, and is arranged between the upper shaft disc 20 and the lower peripheral disc. The opening and closing guide surface 32 is arranged on both sides of the shaft disc contact surface 31, and the guiding member 34 is arranged on the opening and closing guide surface 32, so that when the handle 60 drives the lower shaft disc 40 and then drives the sealing claw 30 to move, the adjacent sealing claws 30 are guided to fit each other through the guiding member 34, and the sealing claw 30 is moved in a direction close to or away from the center of the annular structure of the upper shaft disc 20 and the lower shaft disc 40.

[0051] According to the above structure, during the use of the float glass furnace bubbler replacement auxiliary device, the upper cover 10 or the lower cover 50 of the float glass furnace bubbler replacement auxiliary device is pre-assembled on the bubbler assembly hole, the opening and closing guide surfaces 32 of the surrounding sealing claws 30 are tightly attached to each other, and the opening and closing guide surfaces 32 and the shaft disc contact surface 31 are close to each other toward the inner ring center direction of the annular structure of the upper cover 10, the upper shaft disc 20, the lower cover 50, and the lower shaft disc 40. The inner ring area of ​​the annular structure of the upper cover 10, the upper shaft disc 20, the lower cover 50, and the lower shaft disc 40 is the bubbler assembly hole. When the bubbler is assembled, the bubbler assembly hole is closed.

[0052] When the bubbler needs to be removed for maintenance or replacement, the operator pulls the handle 60, which drives the lower shaft disk 40 to rotate. During the rotation of the second shaft disk groove 41 on the lower shaft disk 40, under the action of the force arm formed between the end of the guide member 34 and the rotating shaft 33, the rotating shaft 33 of the sealing claw 30 is driven to rotate in one direction of the annular structure of the lower shaft disk 40. At the same time, the rotating shaft 33 of the sealing claw 30 is driven in the first shaft disk groove 21 of the upper shaft disk 20 to move in the outer ring direction of the annular structure of the lower shaft disk 40, thereby freeing up space in the inner ring area of ​​the annular structure, so that the bubbler can be removed from the space freed by the inner ring structure of the upper cover 10, the upper shaft disk 20, the sealing claw 30, the lower shaft disk 40 and the lower cover 50. Then, the handle 60 is rotated in the reverse direction, and the sealing claw 30 quickly moves in the reverse direction and approaches each other again toward the inner ring center direction of the annular structure of the upper cover 10, the upper shaft disk 20, the lower cover 50 and the lower shaft disk 40, thereby completing the sealing of the bubbler assembly hole. When assembling the bubbler, the bubbler is placed against the shaft disc contact surface 31 of the sealing claw 30, the sealing claw 30 is opened again by the handle 60, and after the bubbler is inserted, the sealing claw 30 is closed again in the reverse direction, completing the replacement process of the bubbler on the bubbler assembly hole.

[0053] By arranging the upper cover 10, the upper shaft disk 20, the sealing claws 30, the lower shaft disk 40, the handle 60 and the lower cover 50, an annular structure is formed in the kiln area, so that the bubbler can be easily loaded and unloaded between the inner ring surface of the annular structure and the sealing claws 30, and in the process of the bubbler being detached, the sealing claws 30 are guided to fit each other, thereby improving the sealing effect and forming a closed inner ring opening structure of the annular structure, thereby reducing the probability of molten glass overflowing. Compared with setting bricks on site for temporary blocking, the operation of the switch by the handle 60 improves the convenience and safety of the operator.

[0054] Please also read Figures 1 to 6 As a preferred embodiment of the present application, at least one side of the opening and closing guide surface 32 of the sealing claw 30 is connected.
