Description

Technical Field

[0001] This invention relates to the field of coke oven equipment maintenance technology, specifically to a graphite cleaning device and method for coke oven flue pipes. Background Technology

[0002] Coke ovens are key equipment in industries such as metallurgy and chemicals, generating large amounts of flue gas during production. This flue gas is typically collected and guided through flue pipes. Because coke oven flue gas contains free carbon and other substances produced by high-temperature pyrolysis, these substances gradually deposit on the inner wall of the flue pipes, forming a hard and dense graphite layer. Over time, this graphite layer thickens, significantly reducing the effective flow cross-sectional area of ​​the flue pipes. This increases system resistance and affects the smooth exhaust and gas collection efficiency of the coke oven. This not only leads to increased energy consumption and decreased production efficiency but can also cause abnormal oven pressure due to poor flue gas flow, affecting production safety and stability. Furthermore, it hinders the normal operation of subsequent flue gas purification systems.

[0003] Currently, the cleaning of graphite on the inner wall of coke oven flue pipes is generally done manually. Operators must enter or approach a high-temperature environment that may contain residual harmful gases, using long poles with simple tools to poke and scrape. This method has many drawbacks: First, the working environment is harsh, posing a serious threat to personnel health and safety, easily leading to poisoning, burns, and falls from heights; second, manual cleaning is labor-intensive, inefficient, and time-consuming, affecting production continuity; third, the cleaning quality depends entirely on the worker's experience and physical strength, making it difficult to guarantee uniformity and thoroughness, especially for the circumference of the pipe wall and different depth areas, easily leaving blind spots. Furthermore, the impact force of tools on the pipe wall during manual cleaning is difficult to control, posing a risk of damaging the metal inner wall of the flue pipe.

[0004] Although some simple mechanical cleaning devices exist on the market, they are often limited in function and lack overall stability, adjustability, and automated control. For example, the cleaning depth is not easy to control precisely, the cleaning tool is difficult to keep centered and rotate stably, and it cannot adapt to the cleaning needs of different pipe diameters or different degrees of blockage. Furthermore, the portability of the overall equipment, its compatibility with existing coke oven structures, and the ease of operation all need to be improved. Summary of the Invention

To achieve the above objective, this invention provides the following technical solution: a graphite cleaning device for coke oven flue pipes, comprising a fixing component, a balancing component, a supporting component, a lifting component, a rotating component, a cleaning component, a steel frame component, and a control system. The balancing component has two sets fixedly connected to the left and right sides of the lower surface of the fixing component. The balancing component passes through the supporting component and is slidably connected to it. The lifting component is connected between the fixing component and the supporting component, and is used to drive the supporting component to rise and fall relative to the fixing component. A rotating component is mounted on the supporting component, and the rotating component passes through the supporting component and is fixedly connected to the cleaning component. A steel frame component is bolted to the top of the fixing component. A control system is mounted on the steel frame component, and the control system is electrically connected to the lifting component and the rotating component.

[0006] Preferably, the fixing component includes a fixing plate, a fixing steel block, and bolt holes. The fixing steel block is fixedly connected above the fixing plate, and bolt holes are formed on the surface of the fixing steel block.

[0007] Preferably, the balancing assembly includes a limiting tube and a balancing rod. Each set of the balancing assembly includes two limiting tubes. The limiting tubes are fixedly connected to the upper and lower ends of the balancing rod. The limiting tube at the upper end of the balancing rod passes through the fixing plate and is fixedly connected to it. The limiting tube at the lower end constitutes a limit to the downward movement of the support assembly.

[0008] Preferably, the support assembly includes a sleeve and a support plate, with sleeves provided on both the left and right sides of the support plate, and the sleeves slidably connecting to the balance bar through the support plate.

[0009] Preferably, the lifting assembly includes an electro-hydraulic lift, a transmission rod, and a connecting block. The upper end of the electro-hydraulic lift is fixedly connected to a fixed plate, the output end of the electro-hydraulic lift is fixedly connected to a transmission rod, the lower end of the transmission rod is fixedly connected to a connecting block, and a support plate is fixedly connected below the connecting block.

[0010] Preferably, the rotating assembly includes a three-phase asynchronous motor, a drive gear, a chain, a transmission gear, a fixed bearing, and a transmission shaft disc. The fixed bearing and the three-phase asynchronous motor are respectively installed on the left and right sides above the support plate. The output shaft of the three-phase asynchronous motor passes through the support plate and is fixedly connected to the drive gear. The transmission shaft of the fixed bearing passes through the support plate and is fixedly connected to the transmission gear. The drive gear and the transmission gear are connected by a chain meshing. A transmission shaft disc is fixedly connected below the transmission gear.

[0011] Preferably, the cleaning assembly includes a connecting pipe and a brush disc. The connecting pipe is fixedly connected to the lower part of the drive shaft disc, and the brush disc is threadedly connected to the lower part of the connecting pipe. The brush disc bristles are made of bundled steel wires, and the brush disc contains a vibration sensor.

[0012] Preferably, the steel frame assembly includes a steel frame and fixed angle steel, with multiple sets of fixed angle steel provided on the steel frame, and the fixed angle steel being bolted to the fixed steel block through bolt holes.

[0013] Preferably, the control system includes a control box, a PLC, and a control panel. The PLC on the upper left side of the steel frame is electrically connected to the control panel, and the PLC is electrically connected to the vibration sensor inside the brush disc.

[0014] Preferably, it includes the following steps: S1: Installation and positioning: The cleaning device is fixedly installed at a preset position above the coke oven flue pipe to be cleaned using a fixing component; S2: Height adjustment, driven by the control system to operate the lifting component, which in turn drives the support component and the rotating and cleaning components installed on it to descend along the balance component, so that the cleaning component enters the smoke guide pipe to the target cleaning depth; S3: Rotary cleaning, the control system controls the start of the rotating component, drives the cleaning component to rotate, and scrapes and cleans the graphite scale on the inner wall of the flue. S4: Process control. During the cleaning process, the control system coordinates the lifting of the lifting component and the rotation of the rotating component to complete the cleaning of different depth sections of the flue.

[0015] Compared with the prior art, the beneficial effects of the present invention are: The device integrates PLC-controlled lifting and rotating components, enabling automatic lifting and high-speed rotation of the cleaning tool. It replaces inefficient and arduous manual scraping operations, shortening the cleaning time per cycle and improving cleaning efficiency. Automated operation also reduces reliance on skilled operators, lowering labor intensity.

[0016] The motor-driven rotary cleaning method, combined with an electro-hydraulic lifting mechanism that allows for precise control of the lifting stroke, ensures that the wire brush disc moves at a uniform speed and coaxially along the inner wall of the flue. This avoids the randomness and blind spots inherent in manual cleaning, achieving uniform cleaning of the pipe wall with 360-degree coverage and depth, ensuring thorough cleaning. The control system allows for flexible adjustment of the cleaning speed and feed rate to adapt to graphite layers of different thicknesses and hardnesses, optimizing the cleaning effect.

[0017] The device is designed with a balancing component, a fixing component, and a steel frame component. This design ensures that the entire support and actuator maintain a vertical and stable motion posture during the lifting process, allowing the brush to penetrate the smoke duct as smoothly as possible. The brush bristles are made of bundled steel wires, which avoids accidental scratches or impact damage to the inner wall of the smoke duct caused by tool shaking or the brush being too hard. The equipment operates smoothly and reliably. Attached Figure Description

[0024] Please see Figure 1-9 Embodiment 1 of the present invention: A graphite cleaning device for coke oven flue pipes, comprising a fixed component 1, a balancing component 2, a supporting component 3, a lifting component 4, a rotating component 5, a cleaning component 6, a steel frame component 7, and a control system 8. The balancing component 2 has two sets respectively fixedly connected to the left and right sides of the lower surface of the fixed component 1. The balancing component 2 passes through the supporting component 3 and is slidably connected to the supporting component 3. The lifting component 4 is connected between the fixed component 1 and the supporting component 3 and is used to drive the supporting component 3 to lift relative to the fixed component 1. The rotating component 5 is installed on the supporting component 3 and is fixedly connected to the cleaning component 6 through the supporting component 3. The steel frame component 7 is bolted to the top of the fixed component 1. The control system 8 is installed on the steel frame component 7 and is electrically connected to the lifting component 4 and the rotating component 5.

[0025] Specifically, the fixing component 1 includes a fixing plate 101, a fixing steel block 102, and bolt holes 103. The fixing steel block 102 is fixedly connected to the top of the fixing plate 101. Bolt holes 103 are opened on the surface of the fixing steel block 102 to provide a stable mounting base for the entire device and to achieve fastening with the external steel frame through bolt connection.

[0026] Specifically, the balance assembly 2 includes a limiting tube 201 and a balance bar 202. Each balance assembly 2 includes two limiting tubes 201. The limiting tubes 201 are fixedly connected to the upper and lower ends of the balance bar 202. The limiting tube 201 located at the upper end of the balance bar 202 passes through the fixing plate 101 and is fixedly connected to it. The limiting tube 201 located at the lower end constitutes a limit on the downward movement of the support assembly 3, guides and restricts the lifting trajectory of the support assembly 3, ensures the stability of its vertical movement, and prevents it from falling out.

[0027] Specifically, the support component 3 includes a sleeve 301 and a support plate 302. Sleeves 301 are provided on both the left and right sides of the support plate 302. The sleeves 301 pass through the support plate 302 and are slidably connected to the balance bar 202. By sliding along the balance bar 202 through the sleeves 301, stable lifting and lowering motion is achieved, and an installation platform is provided for the rotating component 5.

[0028] Specifically, the lifting assembly 4 includes an electro-hydraulic lift 401, a transmission rod 402, and a connecting block 403. The upper end of the electro-hydraulic lift 401 is fixedly connected to the fixed plate 101, the output end of the electro-hydraulic lift 401 is fixedly connected to the transmission rod 402, the lower end of the transmission rod 402 is fixedly connected to the connecting block 403, and the lower part of the connecting block 403 is fixedly connected to the support plate 302, which serves as the core lifting power source. Through mechanical transmission, the power is transmitted to the support plate 302 to drive it to lift precisely.

[0029] Specifically, the rotating assembly 5 includes a three-phase asynchronous motor 501, a drive gear 502, a chain 503, a transmission gear 504, a fixed bearing 505, and a transmission shaft disc 506. The fixed bearing 505 and the three-phase asynchronous motor 501 are respectively installed on the left and right sides above the support plate 302. The output shaft of the three-phase asynchronous motor 501 passes through the support plate 302 and is fixedly connected to the drive gear 502. The transmission shaft of the fixed bearing 505 passes through the support plate 302 and is fixedly connected to the transmission gear 504. The drive gear 502 and the transmission gear 504 are meshed and connected by the chain 503. The transmission shaft disc 506 is fixedly connected below the transmission gear 504 to provide rotational power. The motor torque is transmitted to the transmission shaft disc 506 through the gear and chain transmission, thereby driving the cleaning assembly 6 to rotate for cleaning operations.

[0030] Specifically, the cleaning component 6 includes a connecting pipe 601 and a brush disc 602. The connecting pipe 601 is fixedly connected to the lower part of the drive shaft disc 506, and the brush disc 602 is threadedly connected to the lower part of the connecting pipe 601. As the terminal component that directly performs the cleaning work, the connecting pipe 601 transmits rotational motion, and the brush disc 602 is responsible for scraping off graphite. The bristles of the brush disc 602 are made of bundled steel wires. A vibration sensor is installed inside the brush disc 602. The high hardness and wear resistance of the steel wires are used to effectively remove hard graphite deposits. The bundled steel wires are designed to avoid accidental scratches to the inner wall of the flue tube caused by the brush disc being too hard.

[0031] Specifically, the steel frame assembly 7 includes a steel frame 701 and fixed angle steel 702. Multiple sets of fixed angle steel 702 are installed on the steel frame 701. The fixed angle steel 702 is bolted to the fixed steel block 102 through bolt holes 103 to form a sturdy external support structure, which securely installs the entire cleaning device above the coke oven or at a specific working position.

[0032] Specifically, the control system 8 includes a control box 801, a PLC 802, and a control panel 803. The control box 801 is installed on the upper left side of the steel frame 701. The control panel 803 is installed on the control box 801. The PLC 802 is installed inside the control box 801. The PLC 802 is electrically connected to the control panel 803. The PLC 802 is also electrically connected to the vibration sensor installed inside the brush plate 602. The PLC 802 integrates electrical control components to realize centralized control, programming, and operation of the lifting, rotating, and other actions of the entire device, thereby improving the level of automation and ease of operation. The PLC 802 transmits the real-time data from the vibration sensor to the control panel 803.

[0033] Specific Implementation Example 2: A method for cleaning graphite in coke oven flue pipes At the coke oven platform of the coking plant, a set of six vertical flue pipes with an inner diameter of 800mm and a height of approximately 15 meters require regular graphite cleaning. The graphite scale thickness is uneven, reaching over 50mm in some areas, and there may be slight deformation or residue inside the pipes. The cleaning process must be safe, thorough, and automatically adaptable to different scaling conditions.

[0034] Control panel 803 displays real-time curve vibration values ​​and motor current. A current transmitter is installed on the power supply circuit of the three-phase asynchronous motor 501 to monitor the motor's operating current in real time.

[0035] The execution process of this embodiment strictly follows the four-step framework described in claim 10, but it is endowed with "adaptive" capabilities through intelligent algorithms.

[0036] Step S1: Installation Positioning and Parameter Preset The operator securely installs the device onto the maintenance steel frame 7 directly above the No. 1 smoke guide pipe using fixing component 1. On the control panel 803, preset the following basic parameters: total cleaning depth 14.5 meters, initial segmented cleaning length 0.5 meters, initial brush speed 150 rpm, and descent speed of the electro-hydraulic lift 401 0.1 meters / minute. Set the adaptive logic thresholds: vibration sensor alarm upper limit 10 m / s², and motor current normal range 15-25 A.

[0037] Step S2: Intelligent Segmented Descent and Cleanup After the system starts, PLC802 controls the electro-hydraulic lift 401 to push the cleaning component 6 down by the first 0.5 meters. Once in position, the rotating component 5 starts, and the brush plate 602 begins cleaning at a speed of 150 rpm.

[0038] Step S3: Adaptive Adjustment Core Based on Real-Time Feedback The PLC802 synchronously acquires vibration values ​​and motor current.

[0039] Scenario A: Normal scaling: Vibration value is stable at 3-5 m / s², and current is around 18A. The PLC determines that the scaling in this section is normal. After cleaning according to the preset time, the automatic command instructs the elevator to descend to the next 0.5 meters.

[0040] Scenario B: Heavy Scale Formation: Vibration value rises to 8 m / s², current approaches the 25A upper limit. The PLC detects the presence of heavy graphite and immediately triggers adaptive strategy 1. a. Reduce the brush speed to 120 rpm to reduce impact.

[0041] b. Shorten the next section of cleaning to 0.3 meters and perform a thorough cleaning.

[0042] c. Appropriately extend the cleaning time for this section.

[0043] Scenario C Abnormal Impedance: Vibration value instantaneously exceeds 10 m / s² or current fluctuates drastically. The PLC immediately triggers adaptive strategy 2 protection strategy: 1. Immediately stop the rotating motor to avoid damage to the equipment.

[0044] 2. Control the lifting platform to raise the brush plate by 100mm.

[0045] 3. Then try restarting the rotation and slowly clear the abnormal point at a lower speed.

[0046] 4. Issue an alarm on the touchscreen to alert the operator.

[0047] Step S4: Full-process coordination and control and report generation Throughout the process, the PLC802 continuously repeats the cycle of "descent → rotation cleaning while monitoring feedback → judgment and parameter adjustment → continued descent".

[0048] The cleanup progress and historical data are displayed in real time on the control panel 803.

[0049] Once the cleaning depth reaches 14.5 meters, the system automatically executes a reset procedure, raising the cleaning components to the top.

[0050] Its working principle is as follows: First, fix the fixing steel block 102 and bolt hole 103 of the fixed component 1, and then fasten the entire device to the fixing angle steel 702 of the steel frame component 7 with bolts.

[0051] Secondly, instructions are input through the control panel 803 of the control system 8, and the PLC 802 inside receives and processes the instructions to prepare for coordinating the actions of the lifting component 4 and the rotating component 5.

[0052] The control system 8 starts the electro-hydraulic lift 401 of the lifting assembly 4. The electro-hydraulic lift 401 pushes the support plate 302 of the support assembly 3 to move vertically downward along the balance bar 202 of the balance assembly 2 through the transmission rod 402 and the connecting block 403 until the brush 602 of the cleaning assembly 6 enters the coke oven flue pipe to be cleaned.

[0053] Simultaneously, the control system 8 starts the three-phase asynchronous motor 501 of the rotating component 5. The motor 501 drives the drive gear 502 to rotate, and the power is transmitted to the transmission gear 504 through the chain 503, which in turn drives the transmission shaft disc 506 and the connecting pipe 601 and brush disc 602 of the cleaning component 6 fixed thereto to rotate at high speed. The bundled steel wire bristles on the brush disc 602 scrape and remove the graphite deposits on the inner wall of the smoke guide pipe.

[0054] During the rotation cleaning process, the lifting component 4 can continue to drive the support component 3 and the cleaning component 6 to slowly rise and fall, so that the rotating brush 602 can cover a larger area of ​​the inner wall of the smoke guide pipe and achieve comprehensive cleaning.

[0055] After the cleaning operation is completed, the rotating component 5 stops working first. Then, the lifting component 4 drives the support component 3 and the cleaning component 6 to rise vertically along the balance bar 202 until they are completely out of the flue and finally return to their initial positions.
