The area covered by the ultrasonic ash collector can be completely cleared of the attached smoke and dust, which not only improves the dust removal effect of the ultrasonic ash collector, but also helps to extend the service life of the equipment. The dust removal efficiency of the ultrasonic ash collector using the knocking cleaning method has been significantly improved compared with the traditional method.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings of the specification. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] Embodiment 1: Combination Figure 1-Figure 9As shown, the present invention provides a technical solution: an acoustic wave ash removal device for a boiler flue gas channel, comprising a pipeline main body 1, a smoke outlet of the pipeline main body 1 connected to a demister (the demister is not shown in the figure), and an acoustic wave ash remover 2 installed on the pipeline main body 1. The working principle of the acoustic wave ash remover 2 is: using compressed air as energy, converting the potential energy of compressed air into acoustic wave energy through an acoustic wave generator or a sound generator, so that a high-strength titanium metal diaphragm self-excites under the action of a compressed air source, and resonates in a harmonic cavity, and these acoustic wave energies are transmitted to the flue gas area in the pipeline main body 1 through an acoustic waveguide to perform acoustic ash removal. As a prior art, the acoustic wave ash remover 2 is not explained in detail. An acoustic waveguide is provided at the output end of the acoustic waveguide, and a fixed frame 3 is provided at the output end of the acoustic waveguide, baffles 4 are symmetrically provided on both sides of the bottom end of the fixed frame 3, and two symmetrical baffles 4 are located at the bottom of the fixed frame 3 to open and close, and a mounting frame 5 is symmetrically provided at the outer end of the baffle 4, and the mounting frame 5 is fixedly installed at the bottom of the fixed frame 3, and a control component 6 is provided on the mounting frame 5;

[0032] The control assembly 6 includes a fixed plate 61 fixedly mounted on the mounting frame 5, and a driving member is arranged on the fixed plate 61, which is the power source of the control assembly and provides power support for the entire assembly. A U-shaped frame 612 is arranged on one side of the driving member. The U-shaped frame 612 has excellent stability and load-bearing capacity, and can withstand the force generated by the pushing member during the working process. The pushing member is a key component in the control assembly, which is responsible for converting the power of the driving member into actual driving force. At the inner end of the pushing member, we set a moving plate 614. The surface of the moving plate 614 is smooth and wear-resistant, and can withstand frequent friction without being easily damaged. On the surface of the moving plate 614, we set a row of uniform first knocking rods 615. These knocking rods are made of high-strength materials and have excellent impact resistance. They can accurately knock the target position during the working process, and On the other side of the driving member, we set up a U-shaped frame 623. The U-shaped frame 623 is not only structurally stable, but also tightly connected to the driving member, ensuring effective transmission of power. A sliding rod 622 is fixedly connected to the top of the U-shaped frame 623. The top of the sliding rod 622 is rotatably connected with a connecting rod 624. The connecting rod 624 is an important component connecting the sliding rod 622 and the second knocking rod 625. It can convert the movement of the sliding rod 622 into the knocking action of the second knocking rod 625. At the other end of the connecting rod 624, we rotatably connect a row of second knocking rods 625 through a positioning seat 626. The first knocking rods 615 cooperate with each other to realize the knocking action on the inner wall of the pipeline body 1. The other end of the second knocking rod 625 corresponds to the position of the inner wall of the pipeline body 1, ensuring that the knocking action can accurately act on the inner wall of the pipeline, thereby realizing effective cleaning of the inside of the pipeline.

[0033] A sliding connection is adopted between the outer wall of the sliding rod 622 and the mounting seat 621. This connection method not only ensures that the sliding rod 622 can flexibly move in the vertical direction, but also ensures the stability of the mounting seat 621. The mounting seat 621 is firmly fixed on the fixing frame 3. This design not only enhances the stability of the entire structure, but also helps the smooth movement of the sliding rod 622. A third damping spring 628 is fixedly connected to the top of the second knocking rod 625, which plays a role of buffering and resetting. The top of the third damping spring 628 is fixedly connected to the top plate 627, and the top plate 627 is also stably fixed on the fixing frame 3. This design not only ensures the stable position of the third damping spring 628, but also helps to evenly disperse the knocking force of the second knocking rod 625 to the pipeline body 1, thereby improving the durability and stability of the entire structure.

[0034] The first knocking rod 615 is mainly composed of a fixed end and a telescopic end. The fixed end is firmly mounted on the movable plate 614. It is not only the supporting base of the entire first knocking rod 615, but also undertakes the important task of transmitting the knocking force to the telescopic end. The telescopic end is slidably mounted on the fixed end. This design enables the telescopic end to be telescopically adjusted when needed to adapt to different working environments and needs. A second damping spring 616 is also sleeved on the fixed end. The second damping spring 616 is located between the telescopic end and the movable plate 614 and plays a buffering role. When the first knocking rod 615 is subjected to external force, the second damping spring 616 can absorb part of the impact force and reduce the vibration and noise of the mechanical structure, thereby improving the stability and reliability of the entire system. In addition, the two ends of the outer side of the moving plate 614 are also slidably connected to the limit frames 613, which are fixedly installed on the fixed plate 61. Their main function is to limit the moving range of the moving plate 614 to prevent it from excessive movement or deviation from the track during operation. At one end of the moving plate 614 away from the first knocking rod 615, a fourth damping spring 629 is also fixedly connected, and the other end of the spring is fixedly connected to the fixed plate 61 to form a stable elastic connection structure. Under the elastic force of the fourth damping spring 629, the moving plate 614 is pulled to move toward the side of the second cam 620. This design enables the moving plate 614 to fit tightly against the outer wall of the second cam 620, achieving smooth sliding and precise knocking action.

[0035] The core component of the driving member is the second motor 66. The second motor 66 is precisely fixed on the fixed plate 61 through a bracket, ensuring its stability and reliability during operation. The output end of the second motor 66 is tightly connected to the first cam 67 to form an efficient driving system. The outer wall of the first cam 67 fits perfectly with the L-shaped guide rod 64. This design not only improves the transmission efficiency, but also ensures the transmission accuracy. The outer end of the L-shaped guide rod 64 is connected to the guide rod 65, and the top of the guide rod 65 is cleverly located at the position of the U-shaped frame 623. This layout enables the driving member to accurately control the position and movement of the U-shaped frame 623 during operation. At the same time, the inner end of the L-shaped guide rod 64 is also connected to the push rod 63, and the other end of the push rod 63 is rotatably connected to the swing rod 62. This structure enables the swing rod 62 to swing with the rotation of the first cam 67, thereby realizing the driving of the U-shaped frame 612.

[0036] It is worth noting that the position of the swing rod 62 corresponds to the position of the U-shaped frame 612, so that the swing of the swing rod 62 can directly act on the U-shaped frame 612 to achieve precise control thereof. In addition, the other end of the swing rod 62 is also rotatably mounted on the fixed plate 61. This design not only ensures the stability of the swing rod 62, but also improves its rotation flexibility.

[0037] A first damping spring 68 is also provided on the side wall of the L-shaped guide rod 64. The other end of the first damping spring 68 is connected to the L-shaped guide rod 64. Its main function is to reduce the vibration and impact of the swing rod 62 during the swinging process, and to make the L-shaped guide rod 64 always fit the outer wall of the first cam 67, thereby improving the stability and life of the entire driving member.

[0038] In addition, a positioning plate 69 is fixedly connected to one side of the top of the fixed plate 61. A first slide groove 610 and a second slide groove 611 are provided on the surface of the positioning plate 69. The two slide grooves provide precise tracks for the sliding of the U-shaped frame 612 and the swing rod 62. The end of the U-shaped frame 612 is slidably installed on the first slide groove 610 laterally, and the return spring arranged in the first slide groove 610 can push the U-shaped frame 612 to slide toward the side of the swing rod 62 in the first slide groove 610, so that the outer wall of the U-shaped frame 612 is closely fitted with the outer wall of the swing rod 62. This design not only ensures the stability of the U-shaped frame 612, but also improves the transmission efficiency between it and the swing rod 62. The swing rod 62 is slidably installed on the second slide groove 611, so that the swing rod 62 can smoothly swing and slide on the second slide groove 611 during the reciprocating rotation. This flexible movement mode enables the driving member to adapt to various complex working environments and changes.

[0039] The driving member also includes a gear rod 617 fixedly mounted on the bottom end of the U-shaped frame 612, and the bottom end of the gear rod 617 is meshedly connected with a gear 619. This connection method enables the linear motion of the gear rod 617 to be converted into the rotational motion of the gear 619. The axis of the gear 619 is rotatably mounted on the fixed plate 61 through a rotating shaft 618. This design not only ensures the stability of the gear 619, but also improves its rotation accuracy. At the same time, a row of second cams 620 fixedly connected to the outer wall of the rotating shaft 618 can slide in contact with the movable plate 614 to realize the driving and control of the movable plate 614.

[0040] In the embodiment of the present invention, when cleaning the smoke and dust sticking on the adjustment plate 49 and the surface of the pipe body 1, we need to use a precise mechanical device to achieve an efficient and thorough cleaning effect. In this process, the second motor 66 plays a vital role. When the second motor 66 is started, it drives the first cam 67 to rotate. The rotation of the first cam 67 is not isolated. It transmits power to the entire cleaning system through the interaction with a series of mechanical parts. During the rotation process, the first cam 67 cooperates closely with the first damping spring 68, the push rod 63 and the L-shaped guide rod 64 to jointly drive the swing rod 62 to swing back and forth on the fixed plate 61. This reciprocating swinging action not only causes the swing rod 62 itself to move, but also And through a series of complex mechanical linkages, the push rod 63, the L-shaped guide rod 64, the guide rod 65 and the first damping spring 68 can also achieve reciprocating movement up, down, left and right. This multi-dimensional movement mode enables the cleaning device to more comprehensively cover the area that needs to be cleaned. During the reciprocating movement of the L-shaped guide rod 64, it will knock and clean the surface of the fixed frame 3 and the bottom of the baffle 4. This knocking force can effectively remove the smoke and dust attached to the surface and restore the surface to a smooth and clean state. At the same time, during the reciprocating swinging process of the swing rod 62, it will also drive the U-shaped frame 612 to slide back and forth on the first slide groove 610 of the positioning plate 69 through the action of the reset spring. This sliding action further enhances the cleaning effect. The sliding of the U-shaped frame 612 Not only does it make the entire cleaning device more flexible, but it also realizes a more complex movement mode through the linkage of the gear rod 617 with the gear 619, the rotating shaft 618 and the second cam 620. During the rotation process, the second cam 620 cooperates with the fourth damping spring 629 to drive the movable plate 614 to slide back and forth on the limit frame 613. This sliding enables the movable plate 614 to cooperate with the second damping spring 616 to drive the first knocking rod 615 to knock the adjustment plate 49 back and forth. This knocking force can penetrate into the tiny gap of the adjustment plate 49 and completely remove the smoke and dust attached thereto. At the same time, during the reciprocating movement of the L-shaped guide rod 64, it will also drive the sliding rod 622 to slide up and down on the mounting seat 621 through the U-shaped frame 623. This up and down sliding action enables the sliding rod 622 to cooperate with the connecting rod 624 and the third damping spring 628 to drive the second knocking rod 625 to reciprocate on the positioning seat 626. This rotation enables the second knocking rod 625 to knock on the inner wall of the top of the pipeline body 1, thereby removing the smoke and dust attached to the inner wall. In this way, the entire cleaning device can achieve comprehensive and efficient cleaning of the smoke and dust sticking to the adjustment plate 49 and the surface of the pipeline body 1. During the operation of the sonic dust remover, the first knocking rod and the second knocking rod reciprocate with a certain frequency and strength. This knocking action can not only penetrate into the tiny gaps of the adjustment plate, but also touch the inner wall of the pipeline body, thereby achieving comprehensive cleaning of the smoke and dust. By knocking,The attached smoke and dust are effectively stripped off and quickly discharged from the pipe with the action of sound waves. In addition, the knocking cleaning method can ensure the thoroughness of cleaning and reduce smoke and dust residue. Traditional dust removal methods often have difficulty reaching some hidden gaps and corners, resulting in serious smoke and dust residue problems. The knocking cleaning method can penetrate into these difficult-to-reach areas and completely remove the attached smoke and dust. This not only improves the dust removal effect of the sonic dust collector, but also helps to extend the service life of the equipment. The sonic dust collector using the knocking cleaning method has significantly improved its dust removal efficiency compared with traditional methods. At the same time, the failure rate of the equipment has also been greatly reduced, reducing the problem of equipment damage caused by smoke and dust residue. In actual applications, the knocking cleaning method has also shown good adaptability and stability. Whether facing high temperature, high humidity or high smoke and dust concentration in harsh environments, the knocking cleaning method can play a stable role to ensure the normal operation and efficient dust removal of the sonic dust collector. ,

[0041] Embodiment 2: Combination Figure 3 , Figure 4 , Figure 5 As shown, on the basis of the first embodiment, the inner cavity of the fixed frame 3 is rotatably connected with a driving rod 41, one end of the driving rod 41 is fixedly connected with a first motor 42, and the first motor 42 is fixedly installed on the outer end of the fixed frame 3, and the two sides of the driving rod 41 are fixedly connected with a disk 43, and the two sides of the disk 43 are hinged with a movable rod 44 through an extension rod, and the other end of the movable rod 44 is rotatably connected with a rotating rod 46, and the other end of the rotating rod 46 is fixedly connected with a V-shaped rod 47, and the connection between the rotating rod 46 and the V-shaped rod 47 is rotatably installed on the fixed frame 3 through a positioning shaft 48, and the other end of the V-shaped rod 47 is hinged to the inner wall of the baffle 4, and the inner end of the top of the baffle 4 is rotatably provided with a connecting rod 45, and the other end of the connecting rod 45 is rotatably connected to the inner wall of the fixed frame 3;

[0042] An adjusting plate 49 is rotatably connected to the inner end of the bottom of the baffle 4 , and a cylinder 410 is provided at the outer end of the adjusting plate 49 , and the end of the cylinder 410 is rotatably mounted on the baffle 4 .

[0043] In the embodiment of the present invention, when it is necessary to remove ash from the flue gas in the boiler channel and open the two baffles 4 from the bottom of the fixed frame 3, the first motor 42 is turned on to drive the driving rod 41 to rotate synchronously, and the driving rod 41 drives the discs 43 on both sides to rotate synchronously. The disc 43 cooperates with the extension rod to drive the V-shaped rod 47 and the rotating rod 46 to rotate with the positioning shaft 48 as the axis. Since one end of the V-shaped rod 47 is hinged to the baffle 4, the V-shaped rod 47 cooperates with the linkage rod 45 to drive the baffle 4 to open from the bottom of the fixed frame 3 to the outside during the rotation process, thereby opening the bottom channel of the fixed frame 3, and then using the acoustic wave dust remover 2 to emit high sound pressure level low-frequency sound waves in the fixed frame 3 and the flue gas channel. , causing a large vibration of small particles of smoke in the flue gas channel, causing the small particles of smoke to rub and collide with each other. Due to the high humidity of the flue gas, the small particles of smoke produce agglomeration effect in the process of mutual friction and collision. Under this effect, the small particles of smoke quickly grow into large particles of smoke. Then, the large particles of smoke are adsorbed by the demister and the smoke is washed away and discharged into the atmosphere, thereby effectively removing small particles of dust, reducing the PM2.5 dust particle content in the exhaust smoke, and reducing air pollution; when it is necessary to adjust the opening size of the acoustic waveguide on the acoustic wave ash remover 2, the cylinder 410 is turned on to drive the adjustment plate 49 to rotate, thereby adjusting the opening size of the acoustic waveguide on the acoustic wave ash remover 2;

[0044] Large-opening sound waveguide: It can produce a wider sound wave diffusion, so that the sound wave can cover a larger area, which is particularly suitable for occasions where a large area of ​​dust needs to be removed, because a larger sound wave coverage means higher dust removal efficiency;

[0045] Sonic waveguide with small opening: The sound wave diffusion range is relatively small, but the sound wave energy is more concentrated. When it is necessary to accurately remove dust in a specific area, the sonic waveguide with small opening is more suitable because it can ensure that the sound wave energy acts directly on the target area and improve the dust removal effect.

[0046] Working principle of the sonic ash removal device for boiler flue gas channels:

[0047] Step 1: Turn on the first motor 42 to drive the driving rod 41 to rotate synchronously, and the driving rod 41 drives the discs 43 on both sides to rotate synchronously, and the disc 43 drives the extension rod to drive the V-shaped rod 47 and the rotating rod 46 to rotate with the positioning shaft 48 as the axis. Since one end of the V-shaped rod 47 is hinged with the baffle 4, the V-shaped rod 47 cooperates with the linkage rod 45 to drive the baffle 4 to open from the bottom of the fixed frame 3 to the outside during the rotation process, thereby opening the bottom channel of the fixed frame 3, and then using the sonic dust remover 2 to remove dust from the flue gas in the boiler channel;

[0048] Step 2: Turn on the second motor 66 to drive the first cam 67 to rotate. The first cam 67 drives the swing rod 62 to swing back and forth on the fixed plate 61 in cooperation with the first damping spring 68, the push rod 63, and the L-shaped guide rod 64 during the rotation process. At the same time, the swing rod 62 cooperates with the rotation of the first cam 67 during the reciprocating rotation process, and can drive the push rod 63, the L-shaped guide rod 64, the guide rod 65 and the first damping spring 68 to reciprocate up and down and left and right. During the reciprocating movement, the L-shaped guide rod 64 can knock and clean the smoke and dust stuck on the bottom surface of the fixed frame 3 and the baffle 4;

[0049] Step 3: During the reciprocating swinging process, the swing rod 62 cooperates with the reset spring to drive the U-shaped frame 612 to slide back and forth on the first slide groove 610 of the positioning plate 69, so that the U-shaped frame 612 cooperates with the fixedly connected gear rod 617 to drive the gear 619, the rotating shaft 618 and the second cam 620 to rotate back and forth, and during the rotation process, the second cam 620 cooperates with the fourth damping spring 629 to drive the moving plate 614 to slide back and forth on the limiting frame 613, so that the moving plate 614 cooperates with the second damping spring 616 to drive the first knocking rod 615 to knock the adjusting plate 49 back and forth, so as to knock and clean the smoke and dust stuck on the surface of the adjusting plate 49;

[0050] Step 4. At the same time, the L-shaped guide rod 64 cooperates with the U-shaped frame 623 to drive the sliding rod 622 to slide up and down on the mounting seat 621 during the reciprocating movement. During the up and down sliding of the sliding rod 622, the connecting rod 624 and the third damping spring 628 drive the second knocking rod 625 on the positioning seat 626 to reciprocate, so that the second knocking rod 625 knocks on the top inner wall of the pipe body 1, thereby knocking and cleaning the smoke and dust sticking to the top inner wall surface of the pipe body 1.
