Description

Technical Field

[0001] This utility model relates to the technical field of annealing furnace equipment, specifically, to an isolation door structure for a tunnel-type oriented silicon steel high-temperature furnace. Background Technology

[0002] In tunnel-type high-temperature oriented silicon steel furnaces, the furnaces are typically arranged in a straight line, with multiple sets of trolleys pushed into the furnace chamber. The secondary holding section and the cooling section need to be separated to prevent heat from the secondary holding section from entering the cooling section. Therefore, the isolation door is a core component in tunnel-type high-temperature oriented silicon steel furnaces. Its function is to create an independent high-temperature processing zone inside the furnace while ensuring stable furnace temperature and gas sealing. However, traditional isolation door structures suffer from insufficient sealing performance, leading to seal failure. Furthermore, hot gas inside the furnace can easily escape from the lifting mechanism of the isolation door, thus affecting its sealing performance. Utility Model Content

[0008] In the above-mentioned isolation door structure for a tunnel-type oriented silicon steel high-temperature furnace, the water seal part includes a water trough arranged around the outside of the sealing groove. The water trough is installed on the door frame, and the four edges of the door seat are provided with downwardly extending water seal plates, which are vertically corresponding to the water trough.

[0016] Combination Figures 1 to 3The diagram illustrates an isolation door structure for a tunnel-type oriented silicon steel high-temperature furnace, comprising a furnace body 1, with at least two furnace cars 2 arranged side-by-side inside the furnace body 1. A liftable isolation door 5 is installed inside the furnace body 1, located between two adjacent furnace cars 2. Longitudinal isolation door guide grooves 4 are provided on both sides of the inner wall of the furnace body 1, and the liftable isolation door 5 is installed within the guide grooves 4. A lifting mechanism is provided on the upper outer side of the furnace body 1, connected to the upper end of the isolation door 5. A sealing part is provided at the lifting point of the lifting mechanism on the isolation door 5, and a water seal is provided on the outer side of the sealing part. In this embodiment, the isolation door 5 can be lifted and lowered by the lifting mechanism, allowing the isolation door 5 to partition the interior of the furnace body 1. Simultaneously, during the isolation process, a double seal is formed through the sealing part and the water seal, greatly improving the sealing effect and preventing hot air in each partition from leaking out from the lifting point of the isolation door 5.

[0017] Specifically, the lifting mechanism includes a gantry 6 installed on the outer side of the upper end of the furnace body 1, a maintenance platform 16 mounted above the gantry 6, a guide rail 17 between the gantry 6 and the maintenance platform 16, a door seat 9 mounted on the upper end of the isolation door 5, the door seat 9 being slidably connected to the guide rail 17, a drive motor 18 mounted on the maintenance platform 16, and the motor shaft of the drive motor 18 being connected to the upper end of the door seat 9 via a chain drive. In some embodiments, a sprocket can be mounted on the door seat 9, so that the motor shaft of the drive motor 18 and the sprocket are connected via a transmission chain, thereby driving the door seat 9 to rise and fall through the isolation door 5 within the isolation door guide groove 4, so as to form partitions within the furnace body 1.

[0018] In this embodiment, a wheel seat 13 is provided at the upper end of the door seat 9, and wheel frames 14 are provided at the upper and lower ends of the outer side of the wheel seat 13. A pulley 15 is installed on the wheel frame 14, and the pulley 15 is in contact with the guide rail 17. There are four guide rails 17, and the wheel frames 14 at the upper and lower ends on the same side form a figure-eight shape. The door seat 9 is limited between the four isolation door guide grooves 4 by the pulley 15. During the lifting and lowering of the door seat 9, the pulley 15 moves on the guide rail 17, and the movement process is smoother and more stable.

[0019] The sealing part of this embodiment includes a sealing groove 7 provided in the lifting part of the door frame 6. The sealing groove is filled with a fire-resistant layer 8. A pressure seat 10 is provided on the lower end face of the door seat 9. A sealing block 11 corresponding to the sealing groove 7 is provided on the lower end of the pressure seat 10. After the isolation door 5 is lowered, the sealing block 11 enters the sealing groove 7 and presses against the fire-resistant layer 8 to seal. In some embodiments, the fire-resistant layer 8 can be a cotton blanket.

[0020] The water seal section includes a water tank 3 surrounding the outside of the sealing groove 7. The water tank 3 is installed on the gantry 6. Water seal plates 12 extending downward are provided around the perimeter of the door seat 9. The water seal plates 12 and the water tank 3 are vertically aligned. After the isolation door 5 is lowered, in addition to sealing between the sealing block 11 and the fire-resistant layer 8, water is injected into the water tank 3 to prevent the sealing section from failing. This water submerges both sides of the water seal plates 12, thereby forming a double seal and further preventing hot air from escaping.

[0021] It is worth noting that a water-cooling pipe 19 is also installed on the door seat 9 in this embodiment, and a water flow channel 20 is opened inside the isolation door 5. The water flow channel 20 is connected to the water-cooling pipe 19. The internal temperature of the isolation door can be reduced by water cooling to prevent the temperature of adjacent zones from being transferred to each other.

[0022] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
