[0002] Nowadays, there are various types of boiler soot blowers sold on the market. The rotary whistle type soot blower is one of them. The rotary whistle type soot blower converts compressed air into sound energy to achieve the purpose of ash cleaning. The sound source adopts a wide frequency range sound wave with an adjustable frequency of 100 - 600 Hz. Its wavelength is long, amplitude is large, energy attenuation is slow, diffraction and reflection capabilities are strong, and the vibration displacement amplitude is large. When using sound waves to clean ash, the action of sound waves can reach the entire space, can produce reverberation in the furnace without dead corners, establish a balanced energy field, the absorption of sound waves by air and the wall surface is small, the effective ash cleaning area is large, and moisture that can corrode the equipment will not be generated, so corrosion and damage will not occur on the tube surface.

[0003] The rotary whistle type acoustic soot blower mainly consists of an acoustic wave generator and a sound duct. The acoustic wave generator includes an acoustic wave modulator and a variable frequency speed regulating motor. During operation, the variable frequency speed regulating motor drives the belt pulley shaft inside the acoustic wave modulator to rotate, continuously cuts off the passage of the supplied air source, and causes air flow disturbance repeatedly, thereby forming continuous high-intensity sound pressure level acoustic wave energy. Finally, it is transmitted to the working space through the sound channel tube to achieve the function of acoustic soot blowing.

[0004] However, the existing rotary whistle type acoustic soot blower has certain defects in actual use. Most of them are fixedly installed by screws during installation, and it is inconvenient to disassemble during damage or maintenance. At the same time, when not in use, it cannot effectively block the rotary whistle type acoustic soot blower from the boiler, and it is easy for dust and other impurities to enter the equipment, affecting the service life of the equipment.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 - 5 , a high-power rotary whistle type acoustic soot blower according to an embodiment of the present utility model includes a main body 2 of an acoustic wave generator, which mainly consists of a rotary whistle type modulator, a variable frequency speed regulation motor, etc. By converting compressed air or steam into high-power acoustic waves, the rotary whistle type sound generator is strictly designed according to acoustic principles, with a large output power. The acoustic wave duct 3 is produced in a customized manner, with good transmission and amplification effects. It is a relatively mature technology and will not be elaborated here. Its bottom is fixedly connected to the mounting plate 4 of the mounting assembly through a positioning mechanism, and the mounting plate 4 can be welded to the boiler wall 1. To ensure its stability, two groups of support rods 5 are obliquely welded between the mounting plate 4 and the boiler wall 1. An acoustic wave duct 3 is installed on the boiler wall 1 (sealing and heat insulation pads, etc. can be provided at the connection to ensure the use effect), and a connecting pipe 17 is connected to the output end of the main body 2 of the acoustic wave generator, which is connected to the acoustic wave duct 3 through an adjustment component.

[0027] Please refer to Figures 1 - 5 , in order to facilitate the installation of the main body 2 of the acoustic wave generator and subsequent disassembly and maintenance operations, a mounting card plate 8 of the positioning mechanism can be welded to the bottom end of the main body 2 of the acoustic wave generator (the cross-section can be T-shaped). A mounting slot 6 adapted to the mounting card plate 8 is opened on the corresponding mounting plate 4. In order to perform positioning and fixing after installation to ensure firmness, a sliding hole 11 of the reset component is opened under the mounting slot 6 on the mounting plate 4. A sliding rod 12 is slidably arranged therein, and a limiting plate 14 is welded to the bottom end. A spring 13 is arranged between the limiting plate 14 and the mounting plate 4, and the spring 13 is sleeved outside the sliding rod 12. A positioning post 9 of the limiting component is welded to the top end of the sliding rod 12. The positioning post 9 slidably passes through the sliding hole 11 and extends into the interior of the mounting slot 6. A positioning hole 10 for inserting and positioning with the positioning post 9 is opened at the end of the corresponding mounting card plate 8, which can position and fix the mounting card plate 8 to prevent sliding.

[0028] Please refer to Figures 1 - 5, in order to conduct the acoustic waveguide 3 and the connecting pipe 17 according to the usage requirements, perform soot blowing operations, and block them when not in use to prevent dust and the like from entering the interior of the acoustic wave generator main body 2 and ensure the service life of the equipment, a sliding groove 7 for the moving component is provided on the mounting plate 4 between the connecting pipe 17 and the acoustic waveguide 3. A screw rod 19 is rotatably arranged inside it. Two moving blocks 20 are engaged with the screw rod 19 through threads. The moving blocks 20 can reciprocate in the sliding groove 7. One end of the screw rod 19 passes through the sliding groove 7 and extends to the outside and is fixedly connected to the output end of the motor 18 through a coupling. The top end of the moving block 20 can be welded with a moving plate 15 of the adjusting component, which can facilitate the rotation of the screw rod 19 to drive the moving plate 15 on the moving block 20 to move. A through hole 21 communicating with the connecting pipe 17 and the acoustic waveguide 3 is provided on the moving plate 15. In order to ensure the sealing performance during connection and closing, sealing rings 16 are bonded to both sides of the through hole 21 and both sides of the moving plate 15 away from the through hole 21. The sealing ring 16 matches the connecting pipe 17 and the acoustic waveguide 3.

[0029] In order to facilitate the understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.

[0030] When installing the acoustic wave generator main body 2, the limit plate 14 can be pulled to drive the sliding rod 12 and the positioning column 9 to slide in the sliding hole 11, move the positioning column 9 out of the installation card slot 6, and the spring 13 is stretched under force to store potential energy. At this time, the installation card plate 8 is inserted into the installation card slot 6 to complete the preliminary assembly. After installation, the limit on the positioning column 9 is lost, and it resets under the action of the potential energy of the spring 13, and then drives the positioning column 9 and the sliding rod 12 to slide and reset. The positioning column 9 enters the positioning hole 10 to limit and fix the installation card plate 8 to ensure stability during use. When performing acoustic wave soot blowing operations, the motor 18 rotates forward, which can drive the screw rod 19 to rotate. The moving block 20 can move on the screw rod 19 to drive the moving plate 15 to move. At this time, the through hole 21 is connected and conducted with the connecting pipe 17 and the acoustic waveguide 3. With the cooperation of the sealing ring 16, the sealing effect can be ensured. Then, through the operation of the acoustic wave generator main body 2, compressed air or steam is converted into a high-power acoustic wave, a pressure wave that propagates in the space medium in the form of a density wave, and is sent into the furnace or a certain space that needs to be soot cleaned. When the ash deposit on the heating surface is repeatedly pulled and pressed by the density waves that alternate at a certain frequency, it becomes loose and falls off due to fatigue and is carried away by the flue gas flow. When not in use, the motor 18 can rotate reversely to drive the moving plate 15 to move back to its original position, and then cooperate with another set of sealing rings 16 and the moving plate 15 to block the connecting pipe 17 to prevent dust and the like from entering the interior of the acoustic wave generator main body 2 and affecting its subsequent use power and service life.

[0031] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
