Description

Technical Field

[0001] This utility model relates to the field of acoustic soot blowers, specifically an acoustic soot blower for boilers. Background Technology

[0002] In the industrial production field, boilers, as important energy conversion equipment, are like the cornerstone of an industrial production building. Their operating efficiency and safety directly and profoundly affect the stability and economic benefits of the entire production process. However, with long-term operation, boilers will accumulate ash and scale on their heating surfaces. This "heat insulation blanket" significantly reduces thermal efficiency, increases fuel consumption, and also brings safety hazards such as tube rupture. Therefore, in order to ensure the normal operation of boilers, sonic soot removers, with their unique principles and advantages, have become a powerful means to solve the problem of ash accumulation.

[0003] However, when using some existing sonic soot removers, the high-viscosity oily ash adhering to the boiler surface is often difficult to break down due to sonic vibrations, requiring frequent shutdowns for manual cleaning. This not only results in low cleaning efficiency but also increases the labor intensity of workers and affects the continuity and stability of production. Utility Model Content

Detailed Implementation

[0014] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0015] Please see Figure 1-4 As shown, a sonic soot blower for boilers includes a soot blowing mechanism body 1. Three connecting rods 2 are fixedly connected to the inner wall of the soot blowing mechanism body 1. One end of each connecting rod 2 is fixedly connected to a spray box 3. The inner cavity of the spray box 3 stores a chemical cleaning agent, which can further clean the boiler surface. A telescopic mechanism 4 is provided within the inner cavity of the spray box 3. Four connecting pipes 6 are connected to one side of the spray box 3. Under these conditions, when the soot blowing mechanism body 1 is used to clean the boiler, an external compressed air source delivers compressed air through one end of the soot blowing mechanism body 1 into its interior. After the compressed air enters the interior of the soot blowing mechanism body 1, a portion of the air drives the telescopic mechanism 4 to squeeze the chemical cleaning agent in the inner cavity of the spray box 3 into the inner cavity of the connecting pipes 6, thus facilitating subsequent use. One end of the device is connected to a connecting shell 7, and several first water pipes 9 are connected to the surface of the connecting shell 7. One end of the first water pipe 9 is equipped with a swing spraying mechanism 10. The part of the first water pipe 9 near the swing spraying mechanism 10 is a flexible hose. Under this action, the chemical cleaning agent in the inner cavity of the connecting pipe 6 will flow through the connecting shell 7 to the inner cavity of the first water pipe 9, and will be sprayed onto the boiler surface by the swing spraying mechanism 10. With the cooperation of the soot blowing mechanism body 1 and the chemical cleaning agent, the efficiency of the soot blowing mechanism body 1 in removing dirt from the boiler surface is further improved. In addition, a part of the compressed air in the inner cavity of the soot blowing mechanism body 1 will drive the swing spraying mechanism 10 to swing, thereby expanding the spraying range of the chemical cleaning agent, ensuring that all parts of the boiler can be thoroughly cleaned, reducing cleaning dead corners, making the cleanliness of the entire boiler surface more consistent, and effectively improving the adaptability of the soot blower.

[0016] A second water pipe 11 is connected to the surface of the spray box 3. The surface of the second water pipe 11 is fixedly connected to the inner wall of the soot blowing mechanism body 1. One end of the second water pipe 11 is connected to a water tank 12. The inner cavity of the water tank 12 stores chemical cleaning agent. The bottom of the water tank 12 is fixedly connected to the surface of the soot blowing mechanism body 1. A second one-way valve 13 is provided on the surface of the second water pipe 11. The second one-way valve 13 only allows the chemical cleaning agent to flow from the water tank 12 to the spray box 3. Under this action, after the telescopic mechanism 4 pushes the chemical cleaning agent in the inner cavity of the spray box 3, the telescopic mechanism 4 will return to its original position. During the retraction process of the telescopic mechanism 4, under the action of negative pressure, the chemical cleaning agent stored in the inner cavity of the water tank 12 will overcome the opening resistance of the second one-way valve 13 and be sucked into the inner cavity of the spray box 3 along the second water pipe 11. This prepares the spraying operation for the next time, ensuring that the oscillating spraying mechanism 10 can continuously and stably obtain chemical cleaning agent for spraying during operation, so as to better complete the cleaning work and improve the working efficiency of the soot blower. The surface of the connecting shell 7 is provided with a first one-way valve 8. The first one-way valve 8 only allows chemical cleaning agent to flow from the connecting pipe 6 to the first water pipe 9. Under this action, when the telescopic mechanism 4 is retracting, due to the presence of the first one-way valve 8, it will prevent the chemical cleaning agent that has not been completely sprayed out of the first water pipe 9 or the inner cavity of the oscillating spraying mechanism 10 from entering the inner cavity of the spray box 3, thereby reducing the situation where chemical cleaning agent flows back into the inner cavity of the spray box 3 and affects the uniformity and effect of spraying, providing a solid guarantee for the efficient and stable operation of the oscillating spraying mechanism 10.

[0017] The telescopic mechanism 4 includes a sealing gasket 41 slidably connected to the inner wall of the spray box 3. A movable plate 42 is fixedly connected to the inner wall of the sealing gasket 41. A spring 43 is fixedly connected to one side of the movable plate 42. One end of the spring 43 is fixedly connected to the inner wall of the spray box 3. A sealing ring 45 is fixedly connected to the inner wall of the spray box 3. A sliding rod 44 is fixedly connected to one side of the movable plate 42. The surface of the sliding rod 44 is slidably connected to the inner wall of the sealing ring 45. Under this action, a portion of the compressed air in the cavity of the blowing mechanism body 1 will cause the movable plate 42 to drive the sliding rod 44 to compress the spring 43, thereby squeezing the chemical cleaning agent in the cavity of the spray box 3 into the cavity of the connecting pipe 6, thus facilitating subsequent use. Under the action of the sealing gasket 41 and the sealing ring 45, the leakage of chemical cleaning agent in the cavity of the spray box 3 can be effectively reduced, ensuring the sealing state of the spray box 3. A limit block 5 is fixedly connected to the inner wall of the spray box 3. The movable plate 42 is used in conjunction with the limiting block 5 to block the movable plate 42 and the sealing gasket 41, thereby preventing excessive displacement of the movable plate 42 and the sealing gasket 41 and causing leakage of chemical cleaning agent in the inner cavity of the spray box 3, ensuring the sealing and stability of the spray box 3. A guide plate 14 is fixedly connected to one side opening of the spray box 3. The guide plate 14 has an inclined structure design. Under this action, the guide plate 14 can guide a part of the compressed air in the inner cavity of the blowing mechanism body 1, so that the compressed air can be more evenly distributed on the surface of the movable plate 42, increasing the force of the air on the movable plate 42, and thus making the telescopic mechanism 4 more effective when in use. The sliding rod 44 is located inside the spring 43. The spring 43 and the sliding rod 44 work together. Under this action, the spring 43 can be guided during compression or rebound, effectively reducing the possibility of large positional displacement of the spring 43.

[0018] The oscillating spraying mechanism 10 includes two mounting plates 104 fixedly connected to the inner wall of the soot blowing mechanism body 1. A rotating rod 105 is rotatably connected to one side of the mounting plate 104, and a rotating column 102 is fixedly connected to one end of the rotating rod 105. A torsion spring 103 is fixedly connected to one side of the mounting plate 104, and one end of the torsion spring 103 is fixedly connected to one end of the rotating column 102. An atomizing nozzle 101 is fixedly connected to the surface of the rotating column 102, and the surface of the atomizing nozzle 101 is fixedly connected to one end of the first water pipe 9. An air diffuser 106 is fixedly connected to the surface of the atomizing nozzle 101. The air diffuser 106 can increase the contact area between the air and the oscillating spraying mechanism 10. Under this action, a portion of the inner cavity of the soot blowing mechanism body 1 is compressed. Air impacts the air diffuser 106, causing it to rotate the atomizing nozzle 101, the rotating column 102, and the rotating rod 105. As the rotating column 102 rotates, it compresses the torsion spring 103. Simultaneously, the chemical cleaning agent inside the first water pipe 9 is sprayed onto the boiler surface through the atomizing nozzle 101, thus expanding the spray range and ensuring that all parts of the boiler are thoroughly cleaned. This reduces cleaning dead zones and ensures a uniform cleanliness across the entire boiler surface, enhancing the sootblower's adaptability. After spraying, the torsion spring 103 causes the atomizing nozzle 101 and the air diffuser 106 to return to their original positions, preparing them for the next use.

[0019] It is worth noting that the technical features such as the soot blowing mechanism body 1 proposed in this technical solution should be regarded as prior art. The specific structure, working principle, and possible control methods and spatial arrangement of these technical features can be selected using conventional methods in this field. This technical solution will not elaborate further.

[0020] Working principle: When the soot blowing mechanism body 1 is used to clean the boiler, the external compressed air source delivers compressed air through one end of the soot blowing mechanism body 1 into its interior. A portion of the compressed air entering the soot blowing mechanism body 1 pushes the moving plate 42 to drive the sliding rod 44 to compress the spring 43, thereby squeezing the chemical cleaning agent stored in the spray box 3 into the inner cavity of the connecting pipe 6, and flowing into the inner cavity of the first water pipe 9 before being sprayed onto the surface of the boiler through the atomizing nozzle 101. With the cooperation of the soot blowing mechanism body 1 and the chemical cleaning agent, the efficiency of the soot blowing mechanism body 1 in removing dirt from the boiler surface is further improved. At the same time, another portion of the compressed air in the inner cavity of the soot blowing mechanism body 1 impacts the air expansion plate 106, thereby causing the air expansion plate 106 to drive the atomizing nozzle 101, the rotating column 102 and the rotating rod 105 to rotate, thereby increasing the spray range of the chemical cleaning agent, ensuring that all parts of the boiler can be thoroughly cleaned, improving the overall cleanliness of the boiler, and effectively enhancing the adaptability of the soot blower.
