Description

Technical Field

[0001] This utility model relates to the field of incinerator technology, specifically to a slag removal and cleaning device for incinerator pipelines. Background Technology

[0002] An incinerator is a device used to treat solid waste, medical waste, and industrial hazardous waste. It converts waste into ash, heat energy, and flue gas through high-temperature combustion, achieving reduction, harmlessness, and resource recovery. Cleaning the incinerator pipelines is a crucial step in ensuring their efficient and safe operation. Addressing issues such as ash accumulation and coking in the pipelines requires specialized cleaning techniques and equipment. Currently, cleaning the inner walls of the pipelines is typically done manually, which poses certain safety hazards. The poor internal environment of the pipelines can negatively impact the health of cleaning personnel, and manual cleaning is inefficient, consequently affecting production efficiency.

[0003] To overcome the above-mentioned defects, the existing technology (Chinese patent application number CN202323487204.6, application date 2023-12-20) for a pipeline cleaning device includes a housing, a drive assembly, and a cleaning assembly. The first end of the housing is connected to the end of the pipeline, and the output end of the drive assembly extends into the housing and connects to the cleaning assembly. The cleaning assembly includes a connecting shaft and a cleaning mechanism. The two ends of the connecting shaft are respectively connected to the output end and the cleaning mechanism. The drive assembly is configured to drive the connecting shaft to move along the length of the pipeline within the pipeline, thereby driving the cleaning mechanism to clean the deposits inside the pipeline. The drive assembly of the pipeline cleaning device drives the cleaning mechanism to move along the length of the pipeline within the pipeline, scraping off the deposits and preventing pipeline blockage, thus ensuring smooth exhaust gas discharge and improving product quality. The cleaning is achieved by the drive assembly driving the cleaning mechanism, improving automation and facilitating increased cleaning efficiency.

[0004] During incineration, inorganic components in the waste, such as metal oxides, aluminosilicates, and unburned carbon particles, undergo physicochemical reactions at high temperatures to form slag. The slag is hard and adheres tightly to the inner wall of the incinerator pipes. The aforementioned device cannot effectively reduce the slag residue adhering to the inner wall of the incinerator pipes during operation, leading to accelerated corrosion of the pipes and preventing the device from thoroughly cleaning the inner wall, thus reducing its operating efficiency. Utility Model Content

[0027] 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.

[0028] Example 1: The stability of the device is improved by the installation of the frame 1, the casters 5, and the support frame 13. Figures 1-2 As shown: It includes a frame 1, an electric motor 2 fixedly connected to the upper surface of the frame 1, and a rotating shaft 3 fixedly connected to the output end of the electric motor 2. A water pump 11 is fixedly connected to the upper surface of the frame 1. A drive shaft 4 is rotatably installed inside the frame 1. Belts are fitted and connected to both the surface of the drive shaft 4 and the surface of the rotating shaft 3. A movable wheel 5 is fixedly connected to the surface of the drive shaft 4. A support frame 13 is fixedly connected to the upper surface of the frame 1. A fixed plate 14 is fixedly connected to the surface of the frame 1. The fixed plates 14 are symmetrically distributed about the center of the frame 1. A movable shaft 20 is rotatably installed inside the water pump 11. An auxiliary stirring shaft 21 is rotatably installed inside the water pump 11. One end of a connecting pipe 12 is fixedly connected to the upper surface of the water pump 11. A spray assembly 10 is fixedly connected to the other end of the connecting pipe 12.

[0029] The staff places the cleaning device at the incinerator pipe inlet, starts the motor 2, and drives the transmission shaft 4 through the belt, causing the moving wheel 5 on the surface of the transmission shaft 4 to rotate, so that the device can smoothly enter the incinerator pipe. After the device enters the incinerator pipe, the water pump 11 is started. The water pump 11 pressurizes and delivers water to the spray assembly 10 through the connecting pipe 12. At the same time, the catalyst box on the upper surface of the frame 1 delivers catalyst into the water pump 11, thereby improving the efficiency of cleaning the inner wall of the incinerator pipe. At the same time, the support frame 13 and the fixing plate 14 improve the stability of the device and reduce the vibration and shaking of the device during operation, thereby reducing the wear between the components, extending the service life of the device, reducing the frequency of equipment maintenance and replacement of parts, reducing operating costs, and ensuring the continuity and reliability of the cleaning work, avoiding the interruption of the cleaning work due to equipment failure and affecting the normal operation of the incinerator.

[0030] In Example 2, unlike Example 1, the working efficiency of the device is improved by setting up the connecting pipe 12, water pump 11, and spray assembly 10. Figures 3-5 As shown: A fixing block 9 is fixedly connected to the upper surface of the frame 1, and a connecting shaft 7 is rotatably installed inside the fixing block 9. A spray assembly 10 is fixedly connected to the surface of the connecting shaft 7. A bevel gear 6 is fixedly connected to both the surface of the connecting shaft 7 and the surface of the rotating shaft 3. A cam 8 is fixedly connected to the surface of the connecting shaft 7. A bevel gear 6 is fixedly connected to both the surface of the connecting shaft 7 and the surface of the moving shaft 20. At the same time, an agitator 22 is fixedly connected to the surface of the moving shaft 20. A belt is sleeved and connected to both the surface of the moving shaft 20 and the surface of the auxiliary agitator 21. A rotating block 23 is fixedly connected to the surface of the auxiliary agitator 21. A sliding groove 24 is opened inside the rotating block 23. A protrusion 25 is slidably connected to the surface of the sliding groove 24.

[0031] When the motor 2 is working, it drives the output shaft 3 to rotate, and through the bevel gear 6, the motor 2 drives the connecting shaft 7 to rotate. The surface of the connecting shaft 7 is equipped with the injection assembly 10, which causes the injection assembly 10 to rotate on the inner wall of the incinerator tube. At the same time, when the motor 2 is working, the bevel gear 6 drives the agitator 22 on the surface of the moving shaft 20 to rotate inside the water pump 11. And when the moving shaft 20 is working, it drives the auxiliary agitator 21 to rotate inside the water pump 11. As the auxiliary agitator 21 rotates, the protrusion 25 moves in the sliding groove 24. The surface sliding reduces the bubbles generated when the water pump 11 reacts with the catalyst, thereby improving the full integration of the catalyst and water. This allows the spray assembly 10 to wash away various residues adhering to the pipe wall and greatly improves cleaning efficiency. It can handle large areas of residue more quickly. At the same time, by rotating the spray assembly 10 to change the spray angle, the water flow can better conform to the shape of the inner wall of the pipe, enhancing the cleaning effect, effectively avoiding cleaning dead corners, ensuring that the inner wall of the pipe is thoroughly cleaned, and reducing friction between the device and the incinerator tube, thus extending the service life of the device.

[0032] In Example 3, unlike Example 2, the use of the striking post 16, spring 17, and baffle 18 reduces the residue remaining on the inner wall of the incinerator pipe. Figures 6-7 As shown: A striking post 16 is slidably connected inside the support frame 13 and inside the fixed plate 14. A limit rod 15 is fixedly connected to the surface of the support frame 13 and the surface of the fixed plate 14. A baffle 18 is slidably connected through the limit rod 15. A baffle 18 is fixedly connected to the surface of the baffle 18. One end of a first spring 17 is fixedly connected to the surface of the baffle 18. The other end of the first spring 17 is fixedly connected to the fixed plate 14. A second spring 19 is fixedly connected to the upper surface of the support frame 13.

[0033] When the connecting shaft 7 rotates, it drives the cam 8 on the surface to rotate. When the cam 8 contacts the striking column 16, the cam 8 pushes the striking column 16 to slide on the surface of the limit rod 15, and causes the first spring 17 on the surface of the fixed plate 14 to extend to the surface of the baffle 18, so that the striking column 16 strikes the incinerator pipe. When the cam 8 moves away from the striking column 16, the first spring 17 drives the striking column 16 back to the initial position, thereby realizing the reciprocating striking of the incinerator pipe, causing the residue attached to the inner wall of the pipe to fall off, while avoiding cleaning dead corners, improving the overall cleaning effect, and preventing the local accumulation of residue in the pipe, ensuring that the entire slag removal and cleaning device can operate stably and clean the pipe continuously, thus improving the working efficiency of the device.

[0034] The above is the entire working process of the device, and all contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0035] 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.
