[0002] After the regeneration furnace has been in operation for a period of time, regular maintenance and inspection are required to ensure the safe and efficient operation of the equipment. The connection and disassembly of the central shaft is an important part of the inspection process. At the same time, when the regeneration furnace fails, such as the central shaft breaks, the bearing is damaged, etc., the central shaft needs to be disassembled for inspection and repair.

[0003] In the prior art, when the existing central axis connection structure is in use, the assembly firmness between the central axis connection structure and the shaft rod is poor, and the connection is easily damaged due to looseness, which reduces the stability of the regeneration furnace operation. At the same time, friction fixation is mostly used when fixing the central axis, which is prone to wear and tear. In view of this, we propose a central axis connection structure for a regeneration furnace. Utility Model Content

[0012] Preferably, a sealing groove matched with a sealing ring is provided on the lower surface of the upper mounting plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) The central axis connection structure of the regeneration furnace uses a mounting plate to synchronously cooperate with the arc plate to drive the limit column to move. After the limit column moves, it synchronously drives the semi-cylinder to move. After the semi-cylinder moves, its cross plate passes over the arc plate. At this time, the semi-cylinder is moved inward. After the movement, the locking column is aligned with the through groove. At this time, the mounting plate is reset so that the locking column enters the interior of the through groove. The same steps are followed on the upper and lower sides to complete the fixation. Through the above structure, the two shafts can be connected more stably and are difficult to loosen. At the same time, they will not wear out due to inertia or insufficient friction, thereby improving the service life of the overall structure.

[0015] (2) The central axis connection structure of the regeneration furnace uses a limit plate to limit its movement space when the semi-cylinder moves. At the same time, when the mounting plate moves in the vertical direction, its movement trajectory and movement range are limited by the limit rod and the triangular plate. At the same time, a sealing ring is used to ensure the sealing after the two mounting plates are fixed by fixing bolts, and the second sealing gasket can be used to ensure the sealing of the connection between the semi-cylinder and the limit column. Through the above structure, the movement trajectory and movement range of each movable component can be strictly limited, and the sealing components such as the sealing ring and the second sealing gasket can be used to ensure the sealing of the structure.
