[0020] 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.

[0021] Please refer to Figures 1-6. This utility model provides a technical solution: an easy-to-maintain acoustic sootblower, including a positioning device 1. The positioning device 1 includes a fixed shell 11, an air inlet pipe 2 fixedly connected to the inner wall of the fixed shell 11 through a connecting hole 12, a loudspeaker pipe 3 fixedly connected to the inner wall of the fixed shell 11, a connecting block 4 slidably connected to the outer wall of the fixed shell 11, and a diaphragm 5 fixedly connected to the outer wall of the connecting block 4. It also includes a connecting device 6, the outer wall of which is fixedly connected to the outer wall of the connecting block 4. The fixed shell 11 of the positioning device 1 provides the installation foundation for the entire sootblower. The connecting hole 12 in its wall is used to fix the air inlet pipe 2, so that compressed air can be stably input into the fixed shell 11. After the air enters, it flows through the amplifier pipe 3 inside the fixed shell 11 and contacts the diaphragm 5. At this time, under the action of pressure, the diaphragm 5 bends. At this time, the air enters the amplifier pipe 3 from the gap between the diaphragm 5 and the inlet of the amplifier pipe 3. After the air flows, the pressure inside the fixed shell 11 changes. Due to the atmospheric pressure on the side of the connecting block 4, the diaphragm 5 on the connecting block 4 re-fits the inlet of the amplifier pipe 3. The vibration of the diaphragm 5 causes the air to vibrate, thereby realizing the soot blowing operation.

[0022] The connecting device 6 includes a connecting plate 61. A limit block 65 is fixedly connected to the side wall of the connecting plate 61, and a limit ring 66 is fixedly connected to the outer wall of the top of the connecting plate 61. A damping rod 62 is symmetrically fixedly connected to the inner wall of the connecting plate 61. A compression spring 63 is sleeved on the outside of the damping rod 62. A pressing plate 64 is fixedly connected to the outer wall of the top of the damping rod 62. The outer wall of the pressing plate 64 is slidably connected to the side wall of the limit block 65 through a limiting groove 68. The inner wall of the pressing plate 64 is slidably connected to the outer wall of the limit ring 66 through an annular groove 69. A push-in groove 67 is opened on the outer wall of the pressing plate 64. The bottom of the connecting plate 61 is fixed to the outer wall of the connecting block 4. The damping rod 62, which is symmetrically fixed on the top, is fitted with a compression spring 63. The top end is connected to a pressing plate 64. When it is necessary to install or remove the connecting block 4, the pressing plate 64 is pressed, the compression spring 63 is compressed, and the damping rod 62 acts as a buffer to slow down the descent speed of the pressing plate 64 and prevent excessive pressing. The pressing plate 64 is slidably connected to the limiting block 65 through the limiting groove 68 and to the limiting ring 66 through the annular groove 69, which ensures that the pressing plate 64 moves smoothly. At the same time, it surrounds and protects the compression spring 63 to prevent dust from entering the compression spring 63 and ensures that the compression spring 63 is not affected by dust in the future, thus ensuring normal use.

[0023] The positioning device 1 also includes a protective shell 13. A snap-fit ​​groove 14 is provided in the wall of the protective shell 13. The outer wall of the protective shell 13 is slidably connected to the outer wall of the pressing plate 64 through a push-in groove 67. The outer wall of the pressing plate 64 is snapped into the inner wall of the protective shell 13 through the snap-fit ​​groove 14. A connecting hole 12 is provided in the wall of the fixed shell 11. The outer wall of the bottom of the connecting plate 61 is fixedly connected to the outer wall of the connecting block 4. The push-in groove 67 provided in the outer wall of the pressing plate 64 is used to assist in inserting the protective shell 13. When the pressing plate 64 is inserted into the protective shell 13 along the push-in groove 67 and reaches the position of the snap-fit ​​groove 14, the pressing plate 64 is released, the compression spring 63 rebounds, and the pressing plate 64 will snap into the snap-fit ​​groove 14 on the inner wall of the protective shell 13, thereby fixing the protective shell 13 and thus fixing the position of the film 5.

[0024] The top end of the compression spring 63 is fixedly connected to the outer wall of the pressing plate 64, and the bottom end of the compression spring 63 is fixedly connected to the inner wall of the connecting plate 61. The annular groove 69 is formed in the wall of the pressing plate 64, and the limiting groove 68 is formed in the wall of the pressing plate 64.

[0025] In use, this acoustic soot blower operates in conjunction with the positioning device 1 and the connecting device 6 to achieve soot blowing while providing convenient maintenance. The fixed shell 11 of the positioning device 1 provides the installation foundation for the entire soot blower. The connecting hole 12 in its wall is used to fix the air inlet pipe 2, allowing compressed air to be stably input into the fixed shell 11. After the air enters, it flows through the amplifier tube 3 inside the fixed shell 11 and contacts the diaphragm 5. At this time, under the action of pressure, the diaphragm 5 bends. Air then enters the amplifier tube 3 through the gap between the diaphragm 5 and the inlet of the amplifier tube 3. After the air flows, the pressure inside the fixed shell 11 changes. Due to the atmospheric pressure on the side of the connecting block 4, the diaphragm 5 on the connecting block 4 re-fits the inlet of the amplifier tube 3 and vibrates, thereby causing the air to vibrate. The amplifier tube 3 connected to the inner wall of the fixed shell 11 can amplify the sound waves, enhance the soot blowing effect, and thus realize the soot blowing operation.

[0026] The connecting device 6 is mainly used to facilitate the maintenance of the protective shell 13. The bottom of the connecting plate 61 is fixed to the outer wall of the connecting block 4. A damping rod 62, which is symmetrically fixed on the plate, is fitted with a compression spring 63. The top of the rod is connected to a pressing plate 64. When the connecting block 4 needs to be installed or removed, the pressing plate 64 is pressed. The compression spring 63 is compressed, and the damping rod 62 acts as a buffer to slow down the descent speed of the pressing plate 64 and prevent excessive pressing. The pressing plate 64 is slidably connected to the limiting block 65 through the limiting groove 68 and to the limiting ring 66 through the annular groove 69, ensuring the pressing plate... The pressure plate 64 moves smoothly while surrounding and protecting the compression spring 63 to prevent dust from entering the compression spring 63, ensuring that the compression spring 63 is not easily affected by dust in the future, thus ensuring normal use. The push-in groove 67 opened on the outer wall of the pressure plate 64 is used to assist in inserting the protective shell 13. When the pressure plate 64 is inserted into the protective shell 13 along the push-in groove 67 and reaches the snap-fit ​​groove 14, the pressure plate 64 is released, the compression spring 63 rebounds, and the pressure plate 64 will snap into the snap-fit ​​groove 14 on the inner wall of the protective shell 13, thereby fixing the protective shell 13 and thus fixing the position of the film 5.

[0027] In daily use, the soot blower ensures the normal operation of the equipment. During maintenance, the connecting device 6 makes the installation and removal of the protective shell 13 simple and convenient, reducing maintenance difficulty and saving maintenance time. At the same time, the damping rod 62 and the compression spring 63 not only ensure the stability of the pressing operation, but also enhance the durability of the device and extend the service life of the equipment.
