The desulfurization pipeline scaling cleaning device includes a support frame and a rotating frame installed on one side of the support frame. A cleaning unit is fixedly installed on the upper end of the rotating frame. When the drive device of the support frame drives inward, the drive motor can drive the rotating frame to rotate, and then the bristles evenly distributed on the upper end rotate and clean the inner cavity of the desulfurization pipeline, so as to prevent scaling in the inner cavity of the desulfurization pipeline from affecting the normal emission of gas.
[0004] The aforementioned device moves within the pipe via the elastic setting of the moving wheels. However, due to the elastic setting of the moving wheels, elastic fatigue and wear occur after prolonged use, causing the aforementioned device to fail to achieve the effect of moving within the pipe.
[0005] In view of this, this utility model is proposed. Summary of the Invention

Detailed Implementation
[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.
[0029] Please refer to Figures 1-5. A scale removal device for the inner wall of a chemical pipeline includes a moving component for moving within the pipeline. The moving component includes a housing 1, a mounting frame 11, and moving wheels 12. The housing 1 and the mounting frame 11 are fixedly connected. The moving wheels 12 are symmetrically arranged on the housing 1 and the mounting frame 11, and one end of the moving wheel 12 is driven by a motor. Each moving wheel 12 passes through the housing 1 and the mounting frame 11. A cleaning component is also included, which is disposed on the housing 1 and the mounting frame 11. The cleaning component is used to clean the inner wall of the pipeline. When the device is placed inside the chemical pipeline, after the moving wheels 12 come into contact with the inner wall of the pipeline, one end of the moving wheel 12 rotates under the drive of the motor. During rotation, the housing 1 and the mounting frame 11 move. This method of movement avoids the failure problem caused by elastic fatigue wear of the elastic connection through the moving wheels. During the movement of the device, the cleaning component cleans the inner wall of the chemical pipeline.
[0030] The dimensions of this device are not fixed. The device of corresponding dimensions is used for chemical pipelines of different sizes. The scope of flexibility in adapting to pipeline size mentioned in the prior art is limited, and therefore it is not a full-size pipeline inner diameter adaptation.
[0031] The cleaning component includes a first bevel gear 13, a second bevel gear 14, and cleaning blocks 3. The first bevel gears 13 are symmetrically arranged on the moving wheels 12, and each first bevel gear 13 meshes with a second bevel gear 14. The corresponding cleaning blocks 3 are elastically connected to the second bevel gear 14, and the cleaning blocks 3 are arrayed on the mounting frame 11. Each cleaning block 3 is driven by a transmission belt 15. Cleaning blocks 3 not elastically connected to the second bevel gear 14 are driven by the transmission belt 15. Each cleaning block 3 is linearly slidably connected to a transmission column 32, and each transmission column 32 is rotatably connected to the mounting frame 11. The corresponding transmission column 32 is fixedly connected to the second bevel gear 14, while the other transmission columns 32 are driven by the transmission belt 15. A first spring 31 is provided between each cleaning block 3 and the transmission column 32, and the end of each first spring 31 is fixedly connected to the corresponding cleaning block 3 and transmission column 32. The moving wheel 12 drives the corresponding first bevel gear 13 during its movement, and the first bevel gear 13 meshes with the second bevel gear 14. The second bevel gear 14 drives the corresponding transmission column 32 to rotate during its movement, and the transmission columns 32 rotate together through the transmission belt 15. The transmission column 32 drives the corresponding cleaning block 3 to rotate during the movement of this device. The cleaning block 3 rotates during its movement and continuously rubs against the inner wall of the chemical pipeline. During the friction, the inner wall of the chemical pipeline is cleaned by friction, realizing rotational friction under linear movement, improving the lateral friction force, and improving the cleaning effect of the inner wall of the chemical pipeline. After the cleaning block 3 contacts the inner wall of the chemical pipeline, it is pushed upward. The cleaning block 3 compresses the first spring 31. The first spring 31 is deformed and applies the deformation force to the cleaning block 3, making the cleaning block 3 in close contact with the inner wall of the chemical pipeline, realizing the stable application of friction force to the inner wall of the chemical pipeline.
[0032] The housing 1 is fixedly connected to a mounting post 2. A drive motor 41 is symmetrically arranged on the mounting post 2, and each drive motor 41 is fixedly connected to the mounting post 2. A connecting rod 42 is fixedly connected to the output end of each drive motor 41. A connecting block 44 is slidably connected to each connecting rod 42, and a cleaning disc 4 is fixedly connected to each connecting block 44. A second spring 43 is provided between the corresponding connecting rod 42 and connecting block 44. The end of each second spring 43 is fixedly connected to the corresponding connecting rod 42 and connecting block 44. During the movement of the device, the drive motor 41 drives the connecting rod through its output shaft. Rotating 42, the connecting rod 42 drives the connecting block 44, which in turn drives the cleaning disc 4. The brushes on the cleaning disc 4 are arranged in a petal shape. With this design, the petal-shaped bristles can be dispersed into different layers to fit complex surfaces and reduce cleaning dead angles. The dense and layered bristles can contact more stains at the same time, improving the efficiency of a single cleaning and making it suitable for emergency treatment of stubborn dirt. When the cleaning disc 4 comes into contact with the inner wall of the chemical pipe, the cleaning disc 4 is pushed to compress the second spring 43. The second spring 43 is deformed and applies the force generated by the deformation to the cleaning disc 4, making the cleaning disc 4 come into close contact with the inner wall of the chemical pipe and improving the cleaning effect.
[0033] The mounting bracket 11 is fixedly connected to a first spray block 5, and the mounting column 2 is fixedly connected to a second spray block 51. The mounting column 2 is inclinedly provided with a scraper 21, which is fixedly connected to the mounting column 2. The scraper 21 is arc-shaped. After the device is placed on the inner wall of the chemical pipeline, the chemical treatment agent is sprayed through the first spray block 5 and the second spray block 51. The treatment agent softens the scale on the inner wall of the chemical pipeline, which facilitates subsequent friction cleaning and avoids the limited cleaning effect of excessive friction due to dirt adhering to the inside of the chemical pipeline. The arc-shaped structure of the scraper 21 scrapes and cleans the inner wall of the chemical pipeline.
[0034] Working Principle: After the device is placed inside the chemical pipeline, the moving wheels 12 contact the inner wall of the pipeline. One end of the moving wheel 12 rotates driven by a motor, which in turn moves the housing 1 and the mounting bracket 11. This movement method avoids the failure problem caused by elastic fatigue wear of the elastic connection through the moving wheels. During the movement of the device, the cleaning components clean the inner wall of the chemical pipeline. After the device is placed inside the chemical pipeline, the first spray block 5 and the second spray block 51 spray a chemical treatment agent, which softens the scale on the inner wall of the chemical pipeline, facilitating subsequent cleaning. Friction cleaning, while effective, avoids dirt adhering to the inside of chemical pipes. However, excessive friction cleaning has limited effectiveness. The arc-shaped structure of the scraper 21 scrapes and cleans the inner wall of the chemical pipes. As the corresponding moving wheel 12 moves, it drives the corresponding first bevel gear 13, which meshes with the second bevel gear 14. The second bevel gear 14, in turn, drives the corresponding transmission column 32 to rotate. The transmission columns 32 rotate together via the transmission belt 15, which in turn drives the corresponding cleaning block 3 to rotate. The movement of this device causes the cleaning block 3 to rotate, and the cleaning block 3 rotates within the chemical pipes. The continuous friction against the wall cleans the inner wall of the chemical pipeline, achieving rotational friction under linear movement, increasing lateral friction, and improving the cleaning effect on the inner wall of the chemical pipeline. After the cleaning block 3 contacts the inner wall of the chemical pipeline, it is pushed upwards, compressing the first spring 31. The first spring 31 deforms and applies the deformation force to the cleaning block 3, ensuring tight contact between the cleaning block 3 and the inner wall of the chemical pipeline, achieving stable application of friction force to the inner wall of the chemical pipeline. During the movement of this device, the drive motor 41 drives the connecting rod 42 to rotate via the output shaft. 2 drives the connecting block 44, which in turn drives the cleaning disc 4. The brushes on the cleaning disc 4 are arranged in a petal shape. With this design, the petal-shaped bristles can be dispersed into different layers to fit complex surfaces and reduce cleaning dead corners. The dense and layered bristles can contact more stains at the same time, improving the efficiency of a single cleaning and making it suitable for emergency treatment of stubborn dirt. When the cleaning disc 4 comes into contact with the inner wall of the chemical pipe, the cleaning disc 4 is pushed to compress the second spring 43. The second spring 43 is deformed and applies the force generated by the deformation to the cleaning disc 4, making the cleaning disc 4 come into close contact with the inner wall of the chemical pipe and improving the cleaning effect.
