Description

Technical Field

[0001] This utility model relates to the field of coke oven door technology, specifically a reinforcing structure for coke oven doors. Background Technology

[0002] Coke oven doors are indispensable key equipment in the coking process, primarily used to seal the coke oven box and prevent heat loss and gas escape. Doors are typically composed of a metal frame and refractory materials, and must operate stably for extended periods under high temperature, high pressure, and frequent opening and closing conditions. Their structural design directly affects the coke oven's sealing performance, thermal efficiency, and production safety. Therefore, the structural strength, high-temperature resistance, and sealing performance of the door are crucial considerations during design and selection.

[0003] The connection between the coke oven door and the oven box needs to balance sealing and ease of operation. In existing technologies, the oven door is typically connected to the side of the oven box via heavy-duty hinges to enable rotating opening and closing. After the door is closed, it is secured to the outside of the oven box using manual or mechanical bolts to ensure a tight fit and thus a good seal. Furthermore, the inside of the oven door is usually sealed with materials such as refractory bricks and ceramic fiber felt to further improve insulation and sealing performance.

[0004] However, traditional furnace door designs have some problems in actual operation. For example, during the furnace door heating process, due to the thermal conductivity and thermal expansion characteristics of the furnace door material, the furnace door will deform under heat, leading to slight loosening of the bolt connections. This not only affects the sealing effect between the furnace door and the furnace box, but may also cause leakage of high-temperature gas inside the furnace, resulting in "smoke." In addition, the deformation of the furnace door may also cause the refractory bricks of the furnace door to fall off, further reducing the sealing and heat insulation performance of the furnace door, ultimately affecting the normal use of the furnace door, and even interfering with the normal production process. Therefore, this utility model proposes a reinforcing structure for coke oven doors to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a reinforcing structure for coke oven doors to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a reinforcing structure for a coke oven door, comprising: an oven door, one side of which is hinged to the oven box, a reinforcing component provided on one side of the oven door, a connecting plate provided on one side of the reinforcing component, one end of the connecting plate being fixedly connected to the oven door, the other end of the connecting plate being detachably connected to the oven box by bolts, and a mesoporous silica layer being fixedly connected to the rear side of the oven door.

[0007] The reinforcing component includes a U-shaped frame fixedly connected to the front side of the furnace door. Limiting covers are fixedly connected to both ends of the U-shaped frame. Limiting holes are opened on the side walls of the limiting covers. A limiting rod is provided on one side of the limiting hole. One end of the limiting rod is slidably connected to the rotating frame. The rotating frame is fixedly sleeved on the connecting shaft. One end of the connecting shaft is rotatably connected to the fixed plate. A worm gear is fixedly sleeved on the other end of the connecting shaft. A worm is meshed on one side of the worm gear.

[0008] Preferably, the upper and lower sides of the furnace door are detachably connected to the furnace box via a buckle assembly, and a handle is provided on one side of the U-shaped frame, with one end of the handle being fixedly connected to the furnace door.

[0009] Preferably, the rear side of the furnace door abuts against the filling frame, the filling frame is provided with an inorganic fiber filling layer, and the side wall of the filling frame is fixedly connected to the inner wall of the furnace box.

[0010] Preferably, the fixing plate is fixedly connected to the furnace box, and four limiting blocks are fixedly connected to the surface of the fixing plate, the four limiting blocks being distributed in a rectangular shape.

[0011] Preferably, the limiting block has a through hole, and both the through hole and the limiting hole are slidably connected to the limiting rod. An arc-shaped hole is provided at the edge of the rotating frame.

[0012] Preferably, the arc-shaped hole is slidably connected to one end of the slide rod, the other end of the slide rod is fixedly connected to the limiting rod, the worm gear is fixedly sleeved on the rotating shaft, the two ends of the rotating shaft are rotatably sleeved on the support seat, and the support seat is fixedly connected to the fixing plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. By strengthening the design of components (including the U-shaped frame, limiting cover, limiting rod, and worm gear transmission mechanism), the sealing between the furnace door and the furnace box is effectively enhanced, avoiding gas leakage and "smoke" caused by furnace door deformation. Simultaneously, the application of mesoporous silica layer and inorganic fiber filling layer significantly improves the furnace door's heat insulation capacity, reduces heat loss, and optimizes the coke oven's thermal efficiency and production safety.

[0015] 2. The inorganic fiber filling layer can alleviate the thermal expansion and deformation of the furnace door under high-temperature conditions, reduce the impact of stress on the furnace door structure, and thus extend the service life of the furnace door and refractory bricks. Furthermore, the improved ease of operation and stability of the components reduces the need for frequent maintenance due to poor sealing, thereby improving equipment reliability and production efficiency.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 4This utility model provides a technical solution: a reinforcing structure for a coke oven door, comprising: an oven door 1, one side of which is hinged to a furnace box 2. Both the oven door 1 and the furnace box 2 are made of heat-resistant steel. One side of the oven door 1 is hinged to the furnace box 2 via a heavy-duty hinge, thereby facilitating the opening and closing of the oven door 1. A reinforcing component is provided on one side of the oven door 1, and a connecting plate 3 is provided on one side of the reinforcing component. One end of the connecting plate 3 is fixedly connected to the oven door 1, and the other end of the connecting plate 3 is detachably connected to the furnace box 2 via bolts 4. Through the cooperation of the connecting plate 3 and the bolts 4, the oven door 1 and the furnace box 2 can be quickly fixed together. A mesoporous silica layer 5 is fixedly connected to the rear side of the oven door 1. The mesoporous silica layer 5 is a mixture of mesoporous silica powder and an inorganic binder such as silica sol. The components are molded into plates or blocks and then fixedly connected to the back side of the furnace door 1, i.e., the side near the inside of the furnace box 2. The reinforcing components include a U-shaped frame 6 fixedly connected to the front side of the furnace door 1. The reinforcing components are used to improve the sealing of the connection between the furnace door 1 and the furnace box 2. Limiting covers 7 are fixedly connected to both ends of the U-shaped frame 6. Limiting holes 8 are opened on the side wall of the limiting cover 7. A limiting rod 9 is provided on one side of the limiting hole 8. One end of the limiting rod 9 is slidably connected to the rotating frame 10. The rotating frame 10 is fixedly sleeved on the connecting shaft 11. One end of the connecting shaft 11 is rotatably connected to the fixing plate 12. The fixing plate 12 limits the connecting shaft 11. A worm gear 13 is fixedly sleeved on the other end of the connecting shaft 11. A worm 14 is meshed on one side of the worm gear 13. The worm 14 meshes with the worm gear 13 for transmission.

[0023] The furnace door 1 and furnace box 2 are rotated by a heavy-duty hinge, closing the furnace door 1 and furnace box 2, causing the connecting plate 3 to abut against the furnace box 2. The connecting plate 3 and furnace box 2 are then fixed together by bolts 4, thus initially sealing the furnace door 1 and furnace box 2. Then, the worm gear 14 meshes with the worm wheel 13, causing the worm wheel 13 to drive the connecting shaft 11 to rotate under the limit of the fixed plate 12. This, in turn, causes the connecting shaft 11 to drive the rotating frame 10 to rotate. The rotating frame 10 rotates through the limit... The sliding connection of the positioning rod 9 pushes the positioning rod 9 into the positioning hole 8 opened on the side wall of the positioning cover 7. Then, the positioning rod 9 is positioned by the insertion of the positioning rod 9 into the positioning hole 8, thereby limiting the U-shaped frame 6 of the positioning cover 7 and finally limiting the furnace door 1. This strengthens the sealing between the furnace door 1 and the furnace box 2. At the same time, the mesoporous silica layer 5 set on the back side of the furnace door 1 can enhance the heat insulation capacity of the furnace door 1, reduce heat loss, and improve the sealing and heat preservation effect of the furnace door 1.

[0024] The furnace door 1 is detachably connected to the furnace box 2 on both the upper and lower sides via a latch assembly. The latch assembly includes a snap-fit ​​part on the furnace door 1 and a mating part on the furnace box 2. The snap-fit ​​part and the mating part interlock to achieve a detachable connection between the furnace box 2 and the furnace door 1. A handle 15 is provided on one side of the U-shaped frame 6, with one end of the handle 15 fixedly connected to the furnace door 1. Pulling the handle 15 facilitates opening the furnace door 1. The rear side of the furnace door 1 abuts against the filling frame 16, which contains an inorganic fiber filling layer, such as glass wool or rock wool. The sidewalls of the filling frame 16 are... The inner wall of the furnace box 2 is fixedly connected to an inorganic fiber filling layer, which can effectively reduce the thermal expansion and deformation of the furnace door 1 under high temperature environment, maintain the tight fit between the furnace door 1 and the furnace box 2, thereby improving the sealing performance. At the same time, the high temperature resistance and heat insulation properties of the inorganic fiber material can further optimize the thermal stability of the furnace door 1, reduce heat loss and gas leakage in the furnace box 2, and reduce production energy consumption. In addition, the filling layer can also alleviate the stress caused by uneven heating during the opening and closing of the furnace door 1, extend the service life of the furnace door 1, and ensure the safety and reliability of equipment operation.

[0025] The fixed plate 12 is fixedly connected to the furnace box 2. Four limiting blocks 17 are fixedly connected to the surface of the fixed plate 12. The four limiting blocks 17 are rectangularly distributed. Through holes 18 are opened in the limiting blocks 17. The through holes 18 and the limiting holes 8 are slidably connected to the limiting rods 9. The limiting blocks 17 limit the limiting rods 9. An arc-shaped hole 19 is opened at the edge of the rotating frame 10. The arc-shaped hole 19 is slidably connected to one end of the slide rod 20. The other end of the slide rod 20 is fixedly connected to the limiting rods 9. The worm gear 14 is fixedly sleeved on the rotating shaft 21. Friction texture is opened on the outer ring surface of the rotating shaft 21 to facilitate the operator to rotate the rotating shaft 21. The two ends of the rotating shaft 21 are rotatably sleeved on the support base 22. The support base 22 is fixedly connected to the fixed plate 12.

[0026] The sealing performance between the furnace door 1 and the furnace box 2 is further improved by the reinforcement components. Specifically, after the furnace door 1 and the furnace box 2 are closed and abutted, the rotating shaft 21 is twisted, which drives the worm gear 14 to rotate. The worm gear 14 then meshes with the worm wheel 13. The worm wheel 13 drives the rotating frame 10 to rotate under the connection of the connecting shaft 11. The rotating frame 10 drives the sliding rod 20 to slide inside the arc-shaped hole 19 opened on it, thereby causing the sliding rod 20 to push the limiting rod 9 to move. The limiting rod 9 slides in the through hole 18 opened in the limiting block 17 until the limiting rod 9 is inserted into the limiting hole 8 opened in the side wall of the limiting cover 7. Then, the limiting cover 7 limits the U-shaped frame 6, and the U-shaped frame 6 limits the furnace door 1, thereby strengthening the sealing performance between the furnace door 1 and the furnace box 2.

[0027] 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.
