Description

Technical Field

[0001] This utility model relates to the field of sealing device technology, and in particular to a sealing structure for a coke oven door. Background Technology

[0002] Currently, the sealing of coke oven doors mainly relies on the rigid contact between the door components and the door frame. When gaps appear between the door components and the door frame during long-term use, the door will not be properly sealed, leading to smoke and fire leakage. This not only causes environmental pollution at the production site but also damages the iron parts of the coke oven and affects its service life. In response, this application proposes a coke oven door sealing structure to solve the above problems. Utility Model Content

[0003] To address the above issues and overcome the problem of gaps between the oven door and frame due to long-term use of coke ovens in existing technologies, resulting in poor sealing, this utility model provides a coke oven door sealing structure. The technical solution includes a coke oven body, characterized in that a door opening is provided at the front end of the coke oven body, a recessed groove is integrally arranged along the circumference of the door opening, and an asbestos gasket is laid at the bottom of the recessed groove. An installation shaft located on the left side of the door opening is fixedly connected to the front end of the coke oven body, and a sealing door that mates with the recessed groove is hinged to the installation shaft. Two horizontally spaced stop blocks are fixedly connected to the front end of the coke oven body, and a short shaft is fixedly connected between the two stop blocks. An installation rod that mates with the stop blocks is rotatably connected to the short shaft. A sealing adjustment device that mates with the sealing door is arranged on the installation rod, and a sealing pressure plate that abuts against the sealing door is fixedly connected to the sealing adjustment device.

[0004] Preferably, the sealing adjustment device includes a first support plate fixedly connected to the mounting rod, two spaced-apart slide rods fixedly connected to the first support plate, and a second support plate directly opposite the first support plate fixedly connected to both slide rods. The first and second support plates are rotatably connected to an adjusting screw located in the middle of the two slide rods. The adjusting screw is threadedly connected to the middle part of a driven rod, and both ends of the driven rod are slidably connected to the two slide rods respectively. Both ends of the driven rod are fixedly connected to support rods, and each support rod is fixedly connected to a sealing pressure rod. The sealing pressure rods correspond one-to-one with and are fixedly connected to the sealing pressure plates.

[0005] Preferably, the mounting rod is integrally provided with a bushing that is rotatably connected to the short shaft.

[0006] Preferably, one end of the adjusting screw extends through the second support plate and is coaxially fixedly connected to an adjusting handwheel.

[0007] The beneficial effects of this utility model are:

[0008] In use, this application features a recessed groove arranged circumferentially at the doorway, with an asbestos gasket fixedly laid within it. When the sealing door is closed, it presses firmly against the asbestos gasket, thus sealing the doorway and preventing smoke and fire from escaping. Furthermore, to prevent gaps from forming between the sealing door and the asbestos gasket during long-term use, a sealing adjustment device is provided. This device adjusts the sealing pressure plate according to the fit between the sealing door and the asbestos gasket, ensuring that the sealing door remains tightly pressed against the asbestos gasket in the recessed groove, thus guaranteeing a tight seal.

[0017] The following is in conjunction with the appendix Figure 1-6 The specific embodiments of this utility model will be described in further detail.

[0018] In the first embodiment, the technical solution is that only the front end face of the coke oven body 1 is depicted in the accompanying drawings. In use, a trough 3 is arranged circumferentially at the door opening 2 of the coke oven body 1, and an asbestos liner is fixedly laid in the trough 3. When the sealing door 6 is closed, it presses firmly against the asbestos liner, thus sealing the door opening 2 and preventing smoke and fire from escaping. Furthermore, to prevent gaps from forming between the sealing door 6 and the asbestos liner during long-term use, a sealing adjustment device 10 is provided. The sealing adjustment device 10 adjusts the sealing pressure plate 11 according to the fit between the sealing door 6 and the asbestos liner, thereby ensuring that the sealing door 6 is always tightly pressed against the asbestos liner in the trough 3, thus ensuring a good sealing effect.

[0019] In Embodiment Two, based on Embodiment One, the sealing door 6 of this application is hinged to the mounting shaft 5 for easy opening and closing. Specifically, in use, to prevent the sealing adjustment device 10 from affecting the normal closing of the sealing door 6, the sealing plug adjustment device is rotatably connected to the short shaft 8 via the bushing 19 on the mounting rod 9. When closing the furnace door, it should be as shown in the accompanying drawings. Figure 6 As shown, first rotate the mounting rod 9 to overlap with the stop 7 on the right side. At this time, the sealing adjustment device 10 also rotates to the right side of the door opening 2, so that the sealing door 6 can be closed and the sealing door 6 and the door opening 2 can be fastened together and pressed on the asbestos gasket.

[0020] Furthermore, after closing the sealing door 6, to ensure a tight seal and lock the sealing door 6, it should be done as shown in the attached diagram of the instruction manual. Figure 1-2 The rotating mounting rod 9 is connected to the left-side stop 7. At this time, the sealing adjustment device 10 will also rotate to the state corresponding to the sealing door 6. Then, the adjusting screw 15 between the first support plate 12 and the second support plate 14 is rotated clockwise. To facilitate the rotation of the adjusting screw 15, an adjusting handwheel 20 is arranged at its end. By rotating the adjusting screw 15 clockwise through the adjusting handwheel 20, the driven rod 16 can be driven by the adjusting screw 15. The driven rod 16 is slidably connected to the slide rod 13. Therefore, driven by the clockwise rotation of the adjusting screw 15, the driven rod 16 will... As the sliding rod 13 moves closer to the sealing door 6, the support rod 17, which is fixedly connected to the driven rod 16, will also move closer to the sealing door 6. At the same time, the sealing pressure rod 18, together with the sealing pressure plate 11, will also move closer to the sealing door 6. The sealing pressure plate 11 can then press the sealing door 6, causing the sealing door 6 to further press the asbestos liner in the settling tank 3, ensuring a sealing effect. Even if the sealing door 6 is used for a long time, the pressure plate can be adjusted by the sealing adjustment device 10 to ensure the tightness and sealing effect of the sealing door 6 and the asbestos liner, avoiding gaps from forming and poor sealing after long-term use.
