Description

Technical Field

[0001] This utility model relates to the field of coking oven technology, specifically to a coking oven top sealing device. Background Technology

[0002] In the coking industry, the coking oven is a crucial piece of production equipment, and the performance of the oven top sealing device directly affects the efficiency, quality, and environmental impact of coking production. A good oven top seal can effectively prevent the leakage of raw coal gas, reduce environmental pollution, and at the same time prevent heat loss, thereby improving energy utilization efficiency.

[0003] Currently, the existing methods for opening the top cover of coking ovens are often quite complex, requiring a lot of manpower and time. This makes it inconvenient for workers to add coal, and may even lead to uneven coal addition, affecting charging efficiency and thus adversely impacting the overall coking production rhythm. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this utility model provides a coking oven top sealing device, which solves the problem that the opening method of the existing coking oven top cover plate is often complicated, requires a lot of manpower and time, and makes it inconvenient for workers to operate when adding coal.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a coking oven top sealing device, comprising a mounting shell, a hydraulic telescopic rod fixedly connected to the outer side of the mounting shell, a movable rod fixedly connected to the bottom of the hydraulic telescopic rod, a sealing cover plate rotatably connected to the top of the movable rod, a counterweight fixedly connected to the top of the sealing cover plate, and a limiting component, the limiting component being fixedly connected to the outer side of the mounting shell, the limiting component including a support column, a piston block slidably connected to the inner wall of the support column, a support rod fixedly connected to the top of the piston block, a pressure roller rotatably connected to the top of the support rod, and a manifold fixedly connected to the bottom of the support column. When the top of the sealing cover plate contacts the pressure roller in the limiting component, the pressure roller slides along the surface of the sealing cover plate and presses the side of the sealing cover plate away from the counterweight downwards, at which point the sealing cover plate can deflect, facilitating the addition of coal to the top of the oven by the operator.

[0008] Preferably, the outer wall of the movable rod is slidably connected to the inner wall of the mounting shell, and the bottom of the sealing cover is engaged with the top of the mounting shell. When the movable rod moves the sealing cover to the top of the mounting shell, the bottom of the sealing cover is engaged with the top of the mounting shell, thus initially achieving a seal on the furnace top.

[0009] Preferably, the bottom of the support column is fixedly connected to both sides of the mounting shell, the outer wall of the support rod is slidably connected to the inner wall of the support column, and the outer wall of the pressure roller is in contact with the top of the sealing cover plate. When hydraulic oil is injected into the support column through the manifold, the piston block pushes the pressure roller upward through the support rod, and vice versa.

[0010] Preferably, a fixing plate is fixedly connected to the outer wall of the movable rod, an arc-shaped rod is slidably connected to the inner wall of the fixing plate, and a pressure plate is fixedly connected to the top of the arc-shaped rod. The pressure plate can limit the excessive deflection of the sealing cover plate through a limiting block.

[0011] Preferably, a tension spring is fixedly connected to the outer side of the arc-shaped rod, and the top end of the tension spring is fixedly connected to the outer side of the fixed plate. The arc-shaped rod can slide along the inner wall of the fixed plate, forcing the tension spring to be stretched.

[0012] Preferably, the sealing cover is rotatably connected to both sides of the limiting block, and the bottom of the limiting block is in contact with the top of the pressure plate. When the sealing cover moves downward, the sealing cover is reset under the action of the counterweight, so that the limiting block presses on the surface of the pressure plate.

[0013] (III) Beneficial Effects

[0014] This utility model provides a sealing device for the top of a coking oven. It has the following beneficial effects:

[0015] (i) The device is equipped with a limiting component. The hydraulic telescopic rod is shortened and the sealing cover is moved up through the movable rod. At this time, the sealing cover is in the open state. When the top of the sealing cover contacts the pressure roller in the limiting component, the pressure roller slides along the surface of the sealing cover and presses the side of the sealing cover away from the counterweight downward. At this time, the sealing cover can be deflected so that the workers can add coal to the top of the furnace.

[0016] (ii) By setting a counterweight, when the sealing cover moves downward, the sealing cover is reset under the action of the counterweight, which causes the limiting block to press on the surface of the pressure plate. At this time, the arc rod slides along the inner wall of the fixed plate, forcing the tension spring to be stretched. The pressure plate can then limit the excessive deflection of the sealing cover through the limiting block. Attached Figure Description

[0022] 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.

[0023] Example: Please refer to Figure 1-4This utility model provides a technical solution: a sealing device for the top of a coke oven, including a mounting shell 1. A hydraulic telescopic rod 2 is fixedly connected to the outer side of the mounting shell 1. A movable rod 3 is fixedly connected to the bottom of the hydraulic telescopic rod 2. A sealing cover plate 4 is rotatably connected to the top of the movable rod 3. A counterweight block 5 is fixedly connected to the top of the sealing cover plate 4. The outer wall of the movable rod 3 is slidably connected to the inner wall of the mounting shell 1. The bottom of the sealing cover plate 4 is engaged with the top of the mounting shell 1. The bottom of the mounting shell 1 is installed on the top of the oven, providing a mounting base for the entire sealing device. When the hydraulic telescopic rod 2 extends and drives the movable rod 3 downward, the sealing cover plate 4 can approach the top of the mounting shell 1 under the action of the movable rod 3. When the movable rod 3 moves the sealing cover 4 to the top of the mounting shell 1, the bottom of the sealing cover 4 engages with the top of the mounting shell 1, initially sealing the furnace top. It also includes a limiting assembly 6, which is fixedly connected to the outside of the mounting shell 1. The limiting assembly 6 includes a support column 61, a piston block 62 slidably connected to the inner wall of the support column 61, a support rod 63 fixedly connected to the top of the piston block 62, a pressure roller 64 rotatably connected to the top of the support rod 63, a manifold 65 fixedly connected to the bottom of the support column 61, and the bottom of the support column 61 fixedly connected to both sides of the mounting shell 1. The outer wall of the support rod 63 slidably connects to the inner wall of the support column 61, and the outer wall of the pressure roller 64 contacts the top of the sealing cover 4. When it is necessary to open the sealing cover 4, the hydraulic telescopic rod 2 shortens and... The sealing cover plate 4 is moved upward by the movable rod 3, at which point the sealing cover plate 4 is in the open state. When the top of the sealing cover plate 4 contacts the pressure roller 64 in the limiting component 6, the pressure roller 64 slides along the surface of the sealing cover plate 4 and presses the side of the sealing cover plate 4 away from the counterweight block 5 downward. At this time, the sealing cover plate 4 can be deflected, so that the operator can add coal to the top of the furnace. When hydraulic oil is injected into the support column 61 through the manifold 65, the piston block 62 pushes the pressure roller 64 upward through the support rod 63, and vice versa, which can drive the pressure roller 64 downward. This can adjust the position of the pressure roller 64, thereby changing the initial position of the sealing cover plate 4 deflection, making it easier for the operator to add coal to the top of the furnace, providing operational convenience for the charging process in the coking production process.

[0024] A fixed plate 8 is fixedly connected to the outer wall of the movable rod 3. An arc-shaped rod 9 is slidably connected to the inner wall of the fixed plate 8. A pressure plate 10 is fixedly connected to the top of the arc-shaped rod 9. A tension spring 11 is fixedly connected to the outer side of the arc-shaped rod 9. The top of the tension spring 11 is fixedly connected to the outer side of the fixed plate 8. Limiting blocks 7 are rotatably connected to both sides of the sealing cover plate 4. The bottom of the limiting block 7 is in contact with the top of the pressure plate 10. When the sealing cover plate 4 moves downward, the sealing cover plate 4 is reset under the action of the counterweight 5, which causes the limiting block 7 to press on the surface of the pressure plate 10. At this time, the arc-shaped rod 9 slides along the inner wall of the fixed plate 8, forcing the tension spring 11 to be stretched. The pressure plate 10 can then limit the excessive deflection of the sealing cover plate 4 through the limiting block 7.

[0025] In use, the bottom of the mounting shell 1 is installed on the furnace top, providing a mounting base for the entire sealing device. When the hydraulic telescopic rod 2 extends and drives the movable rod 3 downward, the sealing cover 4, driven by the movable rod 3, can approach the top of the mounting shell 1. When the movable rod 3 moves the sealing cover 4 to the top of the mounting shell 1, the bottom of the sealing cover 4 engages with the top of the mounting shell 1, initially achieving a seal on the furnace top.

[0026] When it is necessary to open the sealing cover 4, the hydraulic telescopic rod 2 shortens and drives the sealing cover 4 to move upward through the movable rod 3. At this time, the sealing cover 4 is in the open state. When the top of the sealing cover 4 contacts the pressure roller 64 in the limiting component 6, the pressure roller 64 slides along the surface of the sealing cover 4 and presses the side of the sealing cover 4 away from the counterweight 5 downward. At this time, the sealing cover 4 can be deflected so that the workers can add coal to the top of the furnace.

[0027] When hydraulic oil is injected into the support column 61 through the manifold 65, the piston block 62 pushes the pressure roller 64 upward through the support rod 63, and vice versa, thereby driving the pressure roller 64 downward. This adjusts the position of the pressure roller 64, thereby changing the initial position of the sealing cover plate 4, making it easier for workers to add coal to the top of the furnace, and providing operational convenience for the charging process in coking production.

[0028] When the sealing cover 4 moves downward, it resets under the action of the counterweight 5, which causes the limiting block 7 to press on the surface of the pressure plate 10. At this time, the arc rod 9 slides along the inner wall of the fixed plate 8, forcing the tension spring 11 to be stretched. The pressure plate 10 can then limit the excessive deflection of the sealing cover 4 through the limiting block 7.
