Abstract
Description
Technical Field
[0001] This utility model relates to the field of coking furnace technology, specifically to an elastic clamping device for sealing coking furnace doors. Background Technology
[0002] Coking furnaces are critical equipment in the metallurgical and chemical industries, and the sealing performance of their furnace doors directly affects production efficiency, energy consumption, and environmental pollution. Traditional coking furnace doors mostly use rigid clamping or simple spring clamping structures. The furnace door and door frame are prone to thermal deformation at high temperatures, and the rigid clamping structure cannot effectively compensate for this deformation, leading to localized poor sealing and flue gas leakage. Furthermore, simple clamping devices cannot guarantee uniform pressure distribution around the furnace door, and uneven stress on the sealing strip can easily become leakage points. Therefore, there is an urgent need for a device that can automatically compensate for thermal deformation and wear and provide uniform and stable sealing pressure. Utility Model Content
[0003] (a) Technical problems to be solved
[0004] To address the shortcomings of existing technologies, this utility model provides an elastic clamping device for sealing coking furnace doors, which has the advantage of good elastic clamping effect.
[0005] (II) Technical Solution
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an elastic pressing device for sealing the door of a coking furnace, including a door frame, a switch plate is hinged to the left side of the door frame via a hinge assembly, and a cover plate is placed between the switch plate and the door frame.
[0007] Two guide posts are fixedly installed on the front of the cover plate. Two guide holes are opened in the middle of the switch plate. The outer ends of the two guide posts pass through the two guide holes and extend to the outside of the switch plate. A groove is opened on the back of the switch plate. Springs arranged at equal intervals are fixedly installed inside the groove, and the rear end of each spring is fixedly connected to the front of the cover plate.
[0008] A slot is provided on the right side of the switch plate, and a through groove is provided on the inner side wall of the slot. A card plate is placed inside the slot. A push-pull handle is placed on the front side of the switch plate, and the rear end of the push-pull handle passes through the through groove and is fixedly connected to the front of the card plate. A side block is fixedly installed on the right side of the front of the furnace door frame, and a positioning groove is provided on the left side of the side block.
[0009] Furthermore, a limiting plate is fixedly installed at the outer end of each guide post.
[0010] By adopting the above technical solution, the problem of the cover plate coming off can be prevented.
[0011] Furthermore, a ceramic sealing strip is fixedly installed on the front side of the furnace door frame.
[0012] By adopting the above technical solutions, the sealing performance between the furnace door frame and the cover plate can be improved.
[0013] Furthermore, the card plate and card slot are adapted to the positioning slot.
[0014] By adopting the above technical solution, the problem of jamming when moving the cardboard can be avoided.
[0015] Furthermore, the cover plate is larger than the size of the inner frame of the furnace door frame.
[0016] By adopting the above technical solution, the furnace door frame can be more effectively covered by the cover plate.
[0017] (III) Beneficial Effects
[0018] Compared with existing technologies, this elastic clamping device for sealing coke oven doors has the following advantages:
[0019] This utility model, by incorporating a hinge assembly, enables the effective opening and closing of the switch plate during use. A cover plate, when the switch plate is closed, covers the furnace door frame. A ceramic sealing strip enhances the seal, and the elasticity of springs ensures the cover plate remains firmly pressed against the furnace door frame. Furthermore, multiple independent springs allow the cover plate to better compensate for gaps when the furnace door frame deforms slightly, thus improving the device's clamping effect.

Detailed Implementation
[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-7 This utility model provides a technical solution: an elastic clamping device for sealing the furnace door of a coking furnace, including a furnace door frame 1. A ceramic sealing strip 5 is fixedly installed on the front of the furnace door frame 1 to better increase the sealing between the furnace door frame 1 and the cover plate 10. A switch plate 2 is hinged to the left side of the furnace door frame 1 through a hinge assembly 4. The cover plate 10 is placed between the switch plate 2 and the furnace door frame 1. The cover plate 10 is larger than the size of the inner frame of the furnace door frame 1, so that the furnace door frame 1 can be effectively covered by the cover plate 10.
[0030] Two guide posts 8 are fixedly installed on the front of the cover plate 10. A limiting plate 9 is fixedly installed on the outer end of each guide post 8 to prevent the cover plate 10 from falling off. Two guide holes 6 are opened in the middle of the switch plate 2. The outer ends of the two guide posts 8 pass through the two guide holes 6 and extend to the outside of the switch plate 2. A groove 14 is opened on the back of the switch plate 2. Springs 15 arranged at equal intervals are fixedly installed inside the groove 14. The rear end of each spring 15 is fixedly connected to the front of the cover plate 10.
[0031] A slot 16 is provided on the right side of the switch plate 2. A through groove 7 is provided on the inner side wall of the slot 16. A card plate 12 is placed inside the slot 16. A push-pull handle 13 is placed on the front side of the switch plate 2. The rear end of the push-pull handle 13 passes through the through groove 7 and is fixedly connected to the front of the card plate 12. A side block 3 is fixedly installed on the right side of the front of the furnace door frame 1. A positioning groove 11 is provided on the left side of the side block 3. The card plate 12 and the slot 16 are adapted to the positioning groove 11 to avoid jamming when moving the card plate 12.
[0032] Working principle: In use, the furnace door frame 1 is installed at the coking furnace door position by welding or other methods. When in use, the switch plate 2 is rotated to close. After closing, the push-pull handle 13 is pushed to the right to move the locking plate 12 to the right, so that it is locked into the positioning groove 11. When the switch plate 2 is closed, the cover plate 10 covers the outside of the furnace door frame 1, and each spring 15 is compressed to generate rebound potential energy. Thus, in use, multiple independent springs 15 elastically press the cover plate 10 around the whole circle, improving the elastic pressing effect during use and avoiding problems such as flue gas leakage.
[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
