Above both furnace doors 1, a furnace door upper cylinder pressing and sealing device 3 is installed. The furnace door upper cylinder pressing and sealing device 3 includes a driving member one 31, an L-shaped rod 32, a pressing head 33 and a bearing seat 34. The driving member one 31 is fixed above the furnace door frame 5 by bolts. The output end of the driving member one 31 is locked and connected to the upper end of the L-shaped rod 32. The lower end of the L-shaped rod 32 is locked and connected to the pressing head 33. The corner of the L-shaped rod 32 is connected to the bearing seat 34. The bearing seat 34 is fixed on the surface of the furnace door frame 5. Below the furnace door 1, a furnace door lower cylinder pressing and sealing device 4 is installed. The furnace door lower cylinder pressing and sealing device 4 includes a driving member two 41, a straight pressing head 42, a straight pressure guide wheel 43 and a base 44. The output end of the driving member two 41 is connected to the straight pressing head 42 and the straight pressure guide wheel 43 through a universal bearing. The base 44 is installed perpendicular to the furnace door 1. The straight pressure guide wheel 43 is used in cooperation with the base 44. The left end of the base 44 is provided with a triangular inclined surface, and the right end of the base 44 is provided with an upward protrusion to prevent the straight pressure guide wheel 43 from sliding to the right and disengaging from the base 44. The pulley movement range of the straight pressure guide wheel 43 is between the inclined surface and the protrusion of the base 44. There are various choices for the driving members used in the sealing device. For example, machinery such as telescopic motors can all achieve this function. The sealing device cooperates with the rotary power device to more precisely control the door gap, improve the sealing effect, and reduce the leakage of heat and gas.It has a positive impact on both environmental protection and energy conservation. The rotary furnace door can better control the entry and exit of materials, reduce the emission of pollutants such as dust, contribute to improving the cleanliness of the production environment, and conform to the development trend of green environmental protection.

[0015] During use: When the furnace door 1 needs to be opened, the driving part one 31 of the upper cylinder of the furnace door presses the sealing device 3 to start working, reducing the pressure on the furnace door 1, thereby releasing the upper seal. At the same time, the driving part two 41 of the lower cylinder of the furnace door presses the sealing device 4 runs synchronously to release the lower seal. After the sealing device of the furnace door 1 is released, the furnace door rotary opening device 2 is immediately started. The rotary driving part 21 installed outside the furnace door frame 5 is activated to generate a rotary torque. The rotary driving part 21 transmits the power to the furnace door 1 through the guide rod 23. The furnace door 1 rotates through the rotary shafts 22 fixed on both sides. The fixing plate 24 ensures the stable connection between the furnace door 1 and the rotary shafts 22, enabling the furnace door 1 to rotate smoothly along the rotary shafts, thus realizing the opening of the furnace door 1. When the furnace door 1 needs to be closed, the furnace door rotary opening device 2 starts first. The rotary driving part 21 starts to operate, pushing the guide rod 23 to transmit the power to the furnace door 1. The rotary shafts 22 rotate to drive the fixing plate 24 to rotate until the furnace door is closed in place. Subsequently, the driving part one 31 of the upper cylinder of the furnace door presses the sealing device 3 operates, pushing the pressing head 33 downward through the L-shaped rod 32 to ensure that it accurately presses on the upper part of the furnace door 1 to achieve sealing. At the same time, the driving part two 41 of the lower cylinder of the furnace door presses the sealing device 4 starts, applying pressure to the lower part of the furnace door 1 through the direct pressure guide wheel 43 and the direct pressing head 42. The direct pressure guide wheel 43 slides to the right under the action of the driving part two 41 until it is blocked by the convex structure of the base 44. At this time, the direct pressure guide wheel 43 stops sliding, and the pressure of the direct pressing head 42 gradually increases to ensure the sealing of the lower part of the furnace door 1, thereby realizing the complete closing of the furnace door 1.

[0016] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
