Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0018] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0019] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0020] Example 1 like Figure 1 - Figure 4 As shown, an integrated automatic sealing and cleaning device for coke oven doors includes a coke oven body 101. A coke oven inlet 102 is provided on the inner side of the coke oven body 101. Limiting plates 103 are symmetrically fixedly connected to the ends of the coke oven body 101. A receiving plate 104 is fixedly connected between the two limiting plates 103. A coke oven door body 105 is provided between the two limiting plates 103 and between the receiving plate 104 and the coke oven body 101. Travel blocks 106 are symmetrically fixedly connected to both ends of the coke oven door body 105. Travel grooves 107 are provided at the ends of the two limiting plates 103 that are close to each other. The travel blocks 106 are located inside the travel grooves 107 and are slidably connected to them. A base 108 is fixedly connected to the lower ends of the two limiting plates 103.

[0021] A cleaning plate 201 is installed on the inner side of the coke oven inlet 102; The cleaning plate 201 cleans the end of the coke oven door body 105 near the coke oven body 101. Specifically, when the coke oven door body 105 moves longitudinally and when particles are attached to the end of the coke oven door body 105 near the coke oven body 101, the cleaning plate 201 scrapes off the particles. Since the temperature inside the coke oven body 101 is higher than that outside, the scraped particles are adsorbed onto the inside of the coke oven body 101 through the coke oven inlet 102.

[0022] The coke oven door body 105 has symmetrically provided guide grooves 501 and guide rods 502 on its inner side. The inner side of the guide groove 501 is slidably connected to a threaded groove 503, which is fixedly connected to the base 108. The inner side of the guide rod 502 is threadedly connected to a threaded rod 504, which is rotatably connected to the base 108. Rotating the threaded rod 504, which is threadedly connected to the guide rod 502, and the threaded groove 503 is slidably connected to the guide groove 501, causes the coke oven door body 105 to move longitudinally.

[0023] A servo motor 601 is installed at the lower end of the coke oven body 101. A first gear 602 is fixedly connected to the output end of the servo motor 601. A second gear 603 is fixedly connected to the outer side of the lower end of the threaded rod 504. The second gear 603 meshes with the first gear 602. Start the servo motor 601, so that the output end of the servo motor 601 drives the first gear 602 to rotate, and the first gear 602 meshes with the second gear 603, thereby driving the threaded rod 504 to rotate.

[0024] During operation, the servo motor 601 is started, which causes the output end of the servo motor 601 to drive the first gear 602 to rotate. The first gear 602 meshes with the second gear 603, thereby driving the threaded rod 504 to rotate. Then, the threaded rod 504 is threadedly connected to the guide rod 502, causing the coke oven door body 105 to move longitudinally. When it is necessary to seal the coke oven inlet 102, the coke oven door body 105 is controlled to move longitudinally to the upper position, thereby achieving the sealing function of the coke oven inlet 102. When the sealing state needs to be opened, the coke oven door body 105 is controlled to move longitudinally to the lower position, so that the coke oven door body 105 finally stops between the storage plate 104 and the coke oven body 101. This position design can effectively prevent the coke oven door body 105 from staying at the port of the coke oven body inlet 102, thereby preventing particles at the port from adsorbing onto the coke oven door body 105.

[0025] Example 2 like Figure 2 - Figure 5 As shown, A sealing groove 301 is provided at one end of the coke oven body 101 near the limiting plate 103, and a sealing frame 302 is slidably connected to the inner side of the sealing groove 301.

[0026] The coke oven body 101 has a positioning groove 401 on its inner side. Multiple positioning grooves 401 are interconnected with the sealing groove 301. Multiple positioning rods 402 are fixedly connected to one end of the sealing frame 302 near the coke oven body 101. The positioning rods 402 are located inside the positioning grooves 401 and are slidably connected. A spring 403 is provided on the outer side of the positioning rods 402. The two ends of the spring 403 are fixedly connected to the sealing frame 302 and the coke oven body 101, respectively.

[0027] During operation, when the coke oven door body 105 moves upward, the chamfer at the lower end of the sealing frame 302 compresses the sealing frame 302, causing the sealing frame 302 to move away from the end of the coke oven door body 105 inside the sealing groove 301. Then, when the coke oven door body 105 moves to the position to seal the coke oven inlet 102, the elasticity of the spring 403 causes the sealing frame 302 to move closer to the end of the coke oven door body 105, thereby making the sealing frame 302 close to the coke oven door body 105 and improving the sealing effect.

[0028] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
