Description

Technical Field

[0001] This utility model relates to the field of regulating device technology, specifically a temperature regulating device for a tamping coke oven. Background Technology

[0002] The coke oven temperature control device is the core equipment for controlling the temperature stability of the coking process. It achieves temperature balance in the oven by regulating the gas intake, which directly affects the quality of coke and the service life of the coke oven. As a key upstream structure of the device, the gas filter component must effectively intercept impurities such as coke powder and coal dust carried in the gas to prevent impurities from adhering to the valve body and valve core, which could lead to regulation jamming or sealing failure. Therefore, the stability and ease of cleaning of the filter structure are important prerequisites for ensuring the reliable operation of the device.

[0003] Existing temperature control devices for tamping coke ovens generally suffer from two major problems in their filtration mechanisms: Firstly, most filters are fixedly installed, and after long-term use, impurities easily clog the filter pores, requiring the entire filter box to be disassembled and the filter removed to replace or clean it. This not only interrupts coke oven production but also increases the labor intensity of operators. Frequent shutdowns can also cause temperature fluctuations in the oven, affecting the coke maturation effect. Secondly, some filtration devices with simple cleaning functions either rely on electrically controlled cleaning components (such as motor-driven brushes), but the harsh working conditions of high temperature and dust in the coke oven environment can easily lead to failure of the electrical control components, or they use a fixed-frequency mechanical cleaning structure, which cannot adaptively adjust the cleaning intensity according to changes in gas flow. Therefore, this utility model proposes a temperature control device for tamping coke ovens to solve the above problems. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, such as inconvenient cleaning, cumbersome maintenance, and susceptibility to malfunction leading to delayed furnace temperature regulation, this invention incorporates filter screens, air guide plates, tapping plates, and inspection plates to achieve gas impurity filtration, automatic filter screen cleaning, and convenient maintenance. This prevents coke oven production interruptions, furnace temperature fluctuations, and electrical control component failures under high temperature and dust conditions, ensuring stable operation of the unit and precise furnace temperature regulation.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a temperature regulating device for a tamping coke oven, comprising a valve body and a filter box. The air inlet end of the valve body is connected to the filter box via a connecting pipe. An air inlet pipe is fixedly connected to one end of the filter box. Two sets of inner frames are symmetrically arranged on the inner wall of the filter box. A fixed frame is slidably connected between the two sets of inner frames. A filter screen is arranged inside the fixed frame. A rotating shaft is rotatably connected inside the filter box. A striking plate one and a striking plate two are fixedly connected to the outer wall of the rotating shaft. The included angle between the striking plate one and the striking plate two is 120 degrees. The ends of the striking plate one and the striking plate two are in contact with the outer wall of the fixed frame. A buffer mechanism and a triggering mechanism are installed inside the filter box.

[0008] Preferably, the triggering mechanism includes a slide rod slidably connected to the outer walls of two sets of inner frames, the outer wall of the slide rod is V-shaped, the rotating shaft is rotatably connected to the outer wall of the slide rod, and counterweights are fixedly connected to both ends of the striking plate.

[0009] Preferably, the outer wall of the counterweight is equipped with an air guide plate, the outer wall of which is arc-shaped and inclined toward the air intake pipe.

[0010] Preferably, the slide rod slides through one end of the inner frame to the other end, and both ends of the slide rod are fixedly connected to limit blocks, the radius of which is larger than the radius of the slide rod.

[0011] Preferably, a spring is sleeved on the outer wall of the slide rod, one end of the spring is fixedly connected to the limiting block, and the other end of the spring is fixedly connected to the outer wall of the inner frame.

[0012] Preferably, the filter box has a maintenance slot at its upper end, located above the fixed frame, and a maintenance plate is provided at the opening of the maintenance slot.

[0013] (III) Beneficial Effects

[0014] Compared with the prior art, the present invention provides a temperature regulating device for a tamping coke oven, which has the following beneficial effects:

[0015] 1. This utility model, through components such as a fixed frame, an inner frame, and a maintenance plate, utilizes the sliding fit between the fixed frame and the inner frame, as well as the opening and closing control of the maintenance slot at the upper end of the filter box by the maintenance plate, to enable the filter screen to be pulled out for cleaning or replacement without disassembling the entire filter box. This significantly shortens the filter screen maintenance operation time and effectively avoids the problems of coke oven production interruption and furnace temperature fluctuation caused by the need to completely disassemble the filter box for filter screen maintenance in the prior art. At the same time, it reduces the labor intensity of operators and improves the convenience of equipment maintenance and the continuity of coke oven production.

[0016] 2. This utility model utilizes components such as a guide plate, counterweight, rotating shaft, striking plate, and spring. The guide plate bears the force of the gas and drives the counterweight and rotating shaft to rotate synchronously. This allows the striking plate to adaptively generate a striking action on the fixed frame according to changes in gas flow. The spring provides buffer protection for the sliding rod. It can automatically clean the filter screen without relying on electrical control components, effectively avoiding the shortcomings of existing technologies where electrical control cleaning components are prone to failure under high temperature and dust conditions, and fixed-frequency mechanical cleaning cannot adapt to changes in gas flow. This prevents filter screen pore blockage and excessive wear, extends the service life of the filter screen, and improves the overall operational stability of the device. Attached Figure Description

[0021] In this utility model, unless otherwise stated, the orientations used, such as "up" and "down", usually refer to the direction shown in the accompanying drawings, or to the vertical, perpendicular, or gravitational direction; similarly, for ease of understanding and description, "left" and "right" usually refer to the left and right shown in the accompanying drawings; "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0022] This utility model provides a technical solution for a temperature regulation device for a tamping coke oven:

[0023] Please see Figure 1-3A temperature regulating device for a tamping coke oven includes a valve body 1 and a filter box 3. The air inlet end of the valve body 1 is connected to the filter box 3 through a connecting pipe 2. An air inlet pipe 4 is fixedly connected to one end of the filter box 3. Two sets of inner frames 6 are symmetrically arranged on the inner wall of the filter box 3. A fixed frame 7 is slidably connected between the two sets of inner frames 6. A filter screen 8 is arranged in the fixed frame 7. A rotating shaft 9 is rotatably connected in the filter box 3. A striking plate 10 and a striking plate 21 are fixedly connected to the outer wall of the rotating shaft 9. The angle between the striking plate 10 and the striking plate 21 is 120 degrees. The ends of the striking plate 10 and the striking plate 21 are in contact with the outer wall of the fixed frame 7. A buffer mechanism and a triggering mechanism are installed in the filter box 3.

[0024] Furthermore, through the sliding engagement of the two sets of inner frames 6 and the fixed frame 7, the fixed frame 7 can be directly pulled out from the filter box 3, facilitating the cleaning or replacement of the filter screen 8 inside the fixed frame 7. This eliminates the need to disassemble the entire filter box 3 as in existing technologies, effectively preventing coke oven production interruptions and temperature fluctuations caused by filter screen 8 maintenance. Simultaneously, the tapping action of the first tapping plate 10 and the second tapping plate 11 on the fixed frame 7 can promptly shake off the coke powder and coal dust adhering to the filter screen 8, preventing clogging of the filter screen 8 pores, ensuring smooth gas flow, and solving the problem of inconvenient cleaning in existing filtration mechanisms.

[0025] The triggering mechanism includes a slide rod 14 that is slidably connected to the outer wall of the two sets of inner frames 6. The outer wall of the slide rod 14 is V-shaped. The rotating shaft 9 is rotatably connected to the outer wall of the slide rod 14. A counterweight block 12 is fixedly connected to the end of the striking plate 11.

[0026] Furthermore, the V-shaped slide bar 14 can provide stable rotational support for the rotating shaft 9, ensuring that the rotating shaft 9 does not easily deviate when driving the first striking plate 10 and the second striking plate 11. The counterweight 12 at the end of the second striking plate 11 can use its own weight to assist the first striking plate 10 and the second striking plate 11 in resetting.

[0027] A guide vane 13 is installed on the outer wall of the counterweight 12. The outer wall of the guide vane 13 is arc-shaped and inclined towards the air intake pipe 4.

[0028] Furthermore, the arc-shaped air guide plate 13, which is inclined towards the air inlet pipe 4, can more fully receive the gas introduced from the air inlet pipe 4. When the gas flow rate changes, the force of the gas on the air guide plate 13 will change accordingly, thereby driving the counterweight block 12 and the rotating shaft 9 to rotate, so that the striking force of the first striking plate 10 and the second striking plate 11 can be adaptively adjusted according to the gas flow rate.

[0029] The slide bar 14 slides through one end of the inner frame 6 to the other end. Both ends of the slide bar 14 are fixedly connected to limit blocks 15, and the radius of the limit blocks 15 is larger than the radius of the slide bar 14.

[0030] Furthermore, the limiting blocks 15 at both ends of the slide rod 14 can strictly limit the sliding range of the slide rod 14 on the outer wall of the two sets of inner frames 6, preventing the slide rod 14 from sliding excessively due to excessive gas force or long-term use.

[0031] A spring 16 is fitted on the outer wall of the slide rod 14. One end of the spring 16 is fixedly connected to the limiting block 15, and the other end of the spring 16 is fixedly connected to the outer wall of the inner frame 6.

[0032] Furthermore, the spring 16 fitted on the outer wall of the slide rod 14 can provide a buffering force when the slide rod 14 slides due to changes in gas flow, preventing the slide rod 14 from directly colliding with the inner frame 6 and causing damage to the components.

[0033] The filter box 3 has an inspection slot at the top, located above the fixed frame 7, and an inspection plate 5 is provided at the opening of the inspection slot.

[0034] In practical use, the working principle of this utility model is as follows:

[0035] When the coke oven temperature regulation device is put into use, the gas first enters the filter box 3 through the inlet pipe 4. At this time, the coke powder, coal dust and other impurities carried in the gas will first come into contact with the filter screen 8 in the fixed frame 7. The filter screen 8 intercepts and filters the impurities to prevent them from entering the subsequent pipeline with the gas, effectively preventing the valve core inside the valve body 1 from getting stuck or failing to seal due to the adhesion of impurities.

[0036] During the continuous gas supply, the gas flow acts on the air guide plate 13 on the outer wall of the counterweight 12. Since the air guide plate 13 is arc-shaped and inclined towards the air inlet pipe 4, it can fully bear the force of the gas. When the gas flow rate changes, the force on the air guide plate 13 changes accordingly, causing the counterweight 12 to rotate. When the counterweight 12 rotates, it drives the rotating shaft 9 to rotate on the outer wall of the sliding rod 14. The striking plates 10 and 11 fixed to the outer wall of the rotating shaft 9 rotate synchronously, their ends continuously contacting the outer wall of the fixed frame 7 and producing a striking action. This striking action can promptly shake off impurities attached to the filter screen 8, preventing clogging of the filter screen 8 and avoiding the problems of poor gas flow and delayed furnace temperature regulation caused by filter screen clogging in existing technologies. Furthermore, it eliminates the need for electrical control components, effectively avoiding the defects of easily malfunctioning electrical control components under high-temperature and dusty conditions.

[0037] During the rotation of the rotating shaft 9, the slide rod 14 slides on the outer wall of the inner frame 6 according to the force applied to the rotating shaft 9. The limiting blocks 15 at both ends of the slide rod 14 can strictly limit the sliding range of the slide rod 14, preventing the slide rod 14 from slipping excessively and detaching from the inner frame 6 due to excessive gas force or long-term use, thus ensuring that the triggering mechanism always works stably. At the same time, the spring 16 sleeved on the outer wall of the slide rod 14 will generate elastic deformation when the slide rod 14 slides, providing a buffering force for the slide rod 14, avoiding direct collision between the slide rod 14 and the inner frame 6 and causing damage to the components. This makes up for the lack of a buffer structure and easy wear of components in the existing filter mechanism, and extends the overall service life of the device.

[0038] When the filter screen 8 needs to be cleaned or replaced periodically, the operator does not need to disassemble the entire filter box 3. They only need to open the inspection plate 5 at the upper inspection slot of the filter box 3, and the fixing frame 7 can be directly pulled out from between the two sets of inner frames 6 through the inspection slot. This design significantly shortens the maintenance time of the filter screen 8, avoids the problems of coke oven production interruption and furnace temperature fluctuations caused by disassembling the filter box in existing technologies, reduces the labor intensity of operators, and ensures the continuity of coke oven production.

[0039] The clean gas filtered through filter screen 8 enters valve body 1 through connecting pipe 2. Operators adjust the gas intake by regulating the internal structure of valve body 1, thereby achieving precise temperature control within the tamping coke oven. Throughout the temperature regulation process, all components within filter box 3 work collaboratively, ensuring effective gas filtration while automatically cleaning and conveniently maintaining the filter screen. This effectively solves the problems of inconvenient cleaning, cumbersome maintenance, and susceptibility to failure due to operating conditions in existing tamping coke oven temperature regulation devices, ensuring long-term stable operation of the unit.

[0040] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
