Abstract
Description
Technical Field
[0001] This utility model relates to the field of cleaning device technology, specifically a boiler acoustic soot blowing device. Background Technology
[0002] The sonic soot blowing device mainly uses compressed air as a power source. It generates low-frequency, high-energy sound waves through the vibration of the diaphragm cavity, which are then transmitted to the filter through the secondary cavity to achieve the purpose of dust removal. However, during the installation of existing sonic soot blowing devices, the low-frequency vibration can easily cause the bolts to loosen, thus failing to achieve the purpose of dust removal.
[0003] Therefore, in order to solve the aforementioned existing technical problems, Chinese Patent CN220611604U, a vibration-damping acoustic soot blowing device, points out that buffer clamping components are installed on both sides of the acoustic soot blower body. After the fixed flange of the acoustic soot blower body is connected to the connecting flange of the mounting sleeve, the pressure plate of the buffer clamping components presses against the top surface of the fixed flange from above, thus reinforcing the connection between the fixed flange and the connecting flange. This prevents the bolts at the connection between the acoustic soot blower body and the mounting sleeve from loosening over time due to the continuous vibration of the acoustic soot blower body, thereby improving the acoustic soot blowing efficiency. Regarding the stability of the device body after installation, although the aforementioned patent can indeed solve the existing technical problems, certain technical issues still exist. When low-frequency sound waves are transmitted through the secondary cavity, the secondary cavity will also vibrate. However, in the aforementioned patent, the sound tube and the mounting sleeve are fixedly connected, and its support point is relatively simple with a small contact surface. Furthermore, the weights at the secondary cavity and the sound tube are different, so under continuous low-frequency, high-energy vibration, cracks are easily caused at the connection between the sound tube and the mounting sleeve. In addition, the sound wave soot blower body in this patent cannot be disassembled from the mounting sleeve, making it inconvenient to clean the soot blower and the mounting sleeve.
[0004] Therefore, in order to solve the above-mentioned existing technical problems, achieve reliable connection between the secondary chamber and the mounting cylinder, improve the service life of the acoustic soot blowing body, and also achieve a buffering effect, a boiler acoustic soot blowing device is proposed to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a boiler acoustic soot blowing device, comprising an acoustic soot blowing body, which is connected to the boiler via an installation structure. The acoustic soot blowing body and the installation structure are not an integral structure. The installation structure includes a connecting component and a shock-absorbing component. The connecting component includes an arc-shaped mounting plate, a mounting plate, a clamping plate, a mounting cylinder, a clamping body, an internal plate, and a mounting base plate. The shock-absorbing component includes a connector, a shock-absorbing spring, and a sealing plate. Mounting plates are arranged in a ring array on the outer surface of the mounting cylinder. Long strips extend outward from the lower end of the mounting plates. An arc-shaped mounting plate is installed between two adjacent sets of long strips. A circular hole is opened on the surface of the arc-shaped mounting plate. A shock-absorbing component is provided on the surface of the arc-shaped mounting plate. The connector extends through the circular hole to the lower part of the arc-shaped mounting plate. A shock-absorbing spring is sleeved on the surface of the connector. A mounting base plate is installed at the lower end of the connector and connected to the boiler. The sealing plate is divided into two groups, which are bolted together at their ends and installed at the upper opening of the mounting cylinder. The bolts pass through the mounting plate, the clamping plate, and the mounting cylinder, respectively.
[0007] Furthermore, through the above technical solution, the acoustic soot blowing body includes a secondary cavity, a diaphragm cavity, and an air source interface; the diaphragm cavity is installed at the upper end of the secondary cavity, and an air source interface is also provided on the surface of the diaphragm cavity. The internal cavities of the secondary cavity, the diaphragm cavity, and the air source interface are interconnected, and the secondary cavity penetrates the mounting cylinder, and the lower end of the secondary cavity extends to the bottom of the arc-shaped mounting plate.
[0008] Furthermore, the surface of the secondary cavity is also provided with a placement block, wherein two sets of clamping bodies are placed between the upper end face of the sealing plate and the lower end face of the placement block. The two sets of clamping bodies are fixedly installed by bolts, and the inner surfaces of the two sets of clamping bodies are inclined surfaces, which are consistent with the inclination angle of the corresponding secondary cavity surface.
[0009] As a preferred technical solution, the diameter of the connector is smaller from the middle position downwards and larger from the middle position upwards, wherein the larger diameter is larger than the diameter of the circular hole opened on the surface of the arc-shaped mounting plate. Circular plates are provided on both the upper and lower end faces of the connector, and shock-absorbing springs are provided between the surface of the circular plates and the surface of the arc-shaped mounting plate.
[0010] Furthermore, an inner plate is installed on the inner side of the mounting cylinder. A circular hole is opened on the surface of the inner plate. The surface of the circular hole is inclined, and the inclination angle is consistent with the inclination angle of the secondary cavity surface at the corresponding position.
[0011] As a preferred technical solution, the surface of the sealing plate is the same as that of the built-in plate, and the inclined surface of the circular hole is consistent with the surface of the corresponding secondary cavity.
[0012] Furthermore, the clamping plate is mounted on the surface of the mounting plate.
[0013] As a preferred technical solution, the diameter of the placement block is smaller than the diameter of the circular hole after the two sets of sealing plates are aligned.
[0014] Compared with the prior art, this utility model provides a boiler acoustic soot blowing device, which has the following beneficial effects:
[0015] 1. This device has a placement block on the surface of the secondary cavity, which passes through the mounting cylinder and is positioned above the clamping body. It is then fixed by two sets of clamping bodies, thereby stabilizing the secondary cavity. This achieves a connection between the acoustic soot blowing body and the mounting cylinder, which are two separate structures, and facilitates subsequent disassembly and cleaning of both.
[0016] 2. This device, through the built-in plate provided inside the mounting cylinder, wherein the inclined surface of the circular hole of the built-in plate is consistent with the inclined surface of the corresponding secondary cavity, and the circular hole of the clamping body is consistent with the inclined surface of the corresponding secondary cavity, can significantly improve the stability of the secondary cavity. Even if vibration occurs, it can maintain the stability of the secondary cavity well. Furthermore, through the connection relationship between the acoustic soot blowing body and the mounting cylinder, damage caused by vibration at the connection between the secondary cavity and the mounting cylinder will not occur under low-frequency vibration.
[0017] 3. In this device, the diameter of the connecting piece is smaller from the middle downwards and larger from the middle upwards. The larger diameter is larger than the diameter of the circular hole on the surface of the arc-shaped mounting plate. Circular plates are provided on both the upper and lower end faces of the connecting piece. A shock-absorbing spring is provided between the surface of the circular plate and the surface of the arc-shaped mounting plate. This allows the connecting piece to have sufficient room to move, so that it can change accordingly when vibrating, and the shock-absorbing spring can reduce the vibration force.

The shock-absorbing component includes a connecting piece 5 and a shock-absorbing spring 6. The outer surface of the mounting cylinder 4 has mounting plates 2 arranged in a ring array. A long strip extends outward from the lower end of plate 2. An arc-shaped mounting plate 1 is installed between two adjacent sets of long strips. A round hole is opened on the surface of the arc-shaped mounting plate 1. A shock-absorbing component is provided on the surface of the arc-shaped mounting plate 1. A connector 5 extends through the round hole to the bottom of the arc-shaped mounting plate 1. A shock-absorbing spring 6 is sleeved on the surface of the connector 5.

Its sealing plate 11 is divided into two groups and is installed at the upper opening of the mounting cylinder 4 by bolts after the end faces are connected. The bolts pass through the mounting plate 2, the clamping plate 3, and the mounting cylinder 4 respectively.
[0030] In this implementation plan, the specific working principle is as follows: Before use, the secondary chamber 8 is passed through the mounting cylinder 4 from bottom to top. Then, the two sets of sealing plates 11 are aligned and fixed to the upper opening of the mounting cylinder 4 with bolts. At this time, the bolts can simultaneously fix the mounting plate 2, clamping plate 3, mounting cylinder 4, and sealing plate 11. Then, the placement block 12 is positioned above the sealing plate 11. Then, the two sets of clamping bodies 7 are aligned and fixed with bolts, and the upper end face of the clamping body 7 contacts the lower end of the placement block 12. At this time, the secondary chamber 8 is fixed, which enables the connection of the two sets of structures between the sonic soot blowing body and the mounting cylinder 4. This facilitates disassembly and subsequent cleaning. After installation, the lower end of the connector 5 is aligned with the mounting base plate 14, and then the mounting base plate 14 is installed on the boiler with bolts.
[0031] Based on the above, the specific details of the acoustic soot blowing body can be found in [reference needed].

Circular plates are provided on both the upper and lower end faces of the connector 5. A shock-absorbing spring 6 is provided between the surface of the circular plate and the surface of the arc-shaped mounting plate 1. This allows the connector 5 to have sufficient room for movement during vibration, thereby improving the shock absorption effect.
