Abstract
Description
Technical Field
[0001] This utility model belongs to the field of soot remover technology, specifically relating to an acoustic soot remover for thermal power plant boilers. Background Technology
[0002] Currently, most thermal power plant boilers use steam soot blowers to clean the boiler heating surfaces. During each boiler overhaul, it was found that the steam soot blowers on the tail heating surfaces were severely damaged, and this damage was increasing year by year. The number of tubes to be replaced on the tail heating surfaces was increasing annually. Steam soot blowers have a significant impact on the service life of the tail heating surfaces and the safe operation of the unit, causing considerable disruption to production. Acoustic cleaning is more efficient. The acoustic cleaning equipment, technically known as a sonic generator, is an essential device for acoustic cleaning projects. Existing boiler cleaning devices typically have cleaning pipes fixed inside the boiler. However, these pipes inside the boiler wall are prone to loosening due to the sound waves. This loosening can cause the cleaning pipe to collide with the inner wall of the boiler, and prolonged collisions can damage the pipe. Furthermore, the vibration of the cleaning pipe can create gaps in the boiler wall, affecting the boiler's sealing performance. Utility Model Content
[0003] To address the aforementioned problems, this utility model proposes an acoustic soot remover for thermal power plant boilers. When using acoustic waves to clean the boiler, it can prevent rigid collisions between the soot removal pipe and the boiler body, thus preventing damage to the soot removal pipe or the boiler body.
[0004] To achieve the above-mentioned technical objectives and effects, this utility model is implemented through the following technical solution:
[0005] An acoustic soot remover for a thermal power plant boiler, comprising:
[0006] Ash removal pipe;
[0007] The buffer assembly includes a first bearing and a second bearing, which are respectively sleeved on the outer peripheral wall of the cleaning pipe. The outer rings of the first bearing and the second bearing are respectively provided with a first adjusting rod and a second adjusting rod. The ends of the first adjusting rod and the second adjusting rod away from the corresponding bearings are respectively provided with a first slider and a second slider. The first slider and the second slider are slidably mounted on a sliding rod, and the first slider and the second slider are connected by an elastic element. The two ends of the sliding rod are used to connect with the outer peripheral wall of the boiler.
[0008] Optionally, when the cleaning pipe is displaced, it will cause the first adjusting rod and the second adjusting rod to rotate, thereby causing the first slider and the second slider to move relative to each other along the sliding rod.
[0009] Optionally, the outer ring of the first bearing is fixedly connected to the first adjusting rod, or the two are integrally formed.
[0010] Optionally, the outer ring of the second bearing is fixedly connected to the second adjusting rod, or the two are integrally formed.
[0011] Optionally, the buffer assembly further includes an annular buffer block, and the ash removal pipe is positioned and connected to the inner wall of the through hole on the boiler body through the annular buffer block.
[0012] Optionally, the annular buffer block is made of rubber material and is further provided with protrusions for positioning and connection with grooves in the inner wall of the through holes on the boiler body.
[0013] Optionally, the acoustic soot remover for thermal power plant boilers further includes a housing, which is fixedly connected to the outer peripheral wall of the boiler body, and the housing is covered outside the buffer assembly. The two ends of the slide rod are fixedly connected to the housing through fixing rods.
[0014] Optionally, the acoustic soot remover for thermal power plant boilers further includes a fixing plate, which is connected to the shell and used for fixed connection to the outer peripheral wall of the boiler body.
[0015] Optionally, the shape of the fixing plate is adapted to the outer peripheral wall of the boiler body.
[0016] Optionally, the acoustic soot remover for thermal power plant boilers also includes a dustproof net, which is located inside the soot removal pipe.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] 1. The buffer assembly of this utility model includes a first bearing and a second bearing, which are respectively sleeved on the outer peripheral wall of the cleaning pipe. A first adjusting rod and a second adjusting rod are fixedly connected to the outer ring of the first bearing and the second bearing.

[0035] The application principle of this utility model will be described in detail below with reference to the accompanying drawings.
[0036] like Figures 1 to 4 As shown, this utility model provides an acoustic soot remover for a thermal power plant boiler, including a soot removal pipe 2 and a buffer assembly 3. When the acoustic soot remover of this utility model is applied to a boiler, a through hole needs to be opened on the boiler body 1. One end of the soot removal pipe 2 passes through the through hole and is located in the inner cavity of the boiler body 1. The buffer assembly 3 is located on the outer side of the boiler body 1. The buffer assembly 3 includes a first bearing 31 and a second bearing. The first bearing 31 and the second bearing are respectively sleeved on the outer peripheral wall of the soot removal pipe 2. They are arranged sequentially along the axial direction of the soot removal pipe 2. The outer rings of the first bearing 31 and the second bearing are fixedly connected to a first adjusting rod 32 and a second adjusting rod. The ends of the first adjusting rod 32 and the second adjusting rod away from the bearing 31 are respectively provided with a first slider 33 and a second slider. The first slider 33 and the second slider are slidably arranged on a sliding rod 34. An elastic element 35 is provided between the first slider 33 and the second slider. In a specific implementation, the elastic element 35 can be a spring. The two ends of the elastic element 35 are respectively connected to the first slider 33 and the second slider. The two ends of the sliding rod 34 are fixedly connected to the outer peripheral wall of the boiler body 1.
[0037] It should be noted that the cleaning pipe 2 has two opposite ends, one end of which is defined as the input end and the other end as the output end. The output end of the cleaning pipe 2 passes through the boiler body 1 and is located inside the boiler body 1, while the input end is located outside the boiler body 1. When it is necessary to clean the boiler body 1, the input end of the cleaning pipe 2 is connected to the sound wave generating device, and the output end of the cleaning pipe 2 acts on the inner wall of the boiler body 1 to clean the boiler body 1.
[0038] It should be noted that the sound wave generating device is existing technology. It mainly uses compressed air as a power source to make the diaphragm vibrate in the resonant cavity of the generator, generating characteristic low-frequency and high-energy body waves, which act on the surface of the dusty object, causing the dust to fatigue and peel off. This utility model will not elaborate on this.
[0039] In one specific embodiment of this utility model, the two ends of the slide rod 34 are fixedly connected to the outer wall of the boiler body 1, which can prevent the slide rod 34 from being displaced relative to the outer wall of the boiler body 1.
[0040] In one specific embodiment of this utility model, the first bearing 31 and the second bearing can be welded to the first adjusting rod 32 and the second adjusting rod, or they can be integrally formed during the production process. It can be understood that with such a design, the adjusting rod 32 can rotate relative to the dust removal pipe 2.
[0041] In one specific embodiment of this utility model, when the cleaning pipe 2 is displaced, it drives the adjusting rod 32 to rotate, thereby causing the first slider 33 and the second slider to move along the sliding rod 34. Specifically, when the cleaning pipe 2 moves downward, the two adjusting rods 32 rotate, and the two sliders 33 move on the sliding rod 34 in a direction away from each other; when the cleaning pipe 2 moves upward, the first adjusting rod 32 and the second adjusting rod rotate, and the first slider 33 and the second slider move on the sliding rod 34 in a direction closer to each other.
[0042] In one specific embodiment of this utility model, the first slider 33 and the second slider are connected by an elastic member 35. The elastic member 35 can prevent the first slider 33 and the second slider from moving away from each other or moving closer to each other, thereby limiting the up and down movement of the cleaning pipe 2.
[0043] In one specific embodiment of this utility model, the buffer component 3 can prevent the cleaning pipe 2 from rigidly colliding with the boiler body 1 when using sound waves to clean the boiler body 1. It can also be understood that the buffer component 3 provides a certain buffering force to prevent damage to the cleaning pipe 2 or the boiler body 1.
[0044] In one specific embodiment of this utility model, the acoustic soot remover for thermal power plant boilers further includes an annular buffer block 4, which is embedded in the inner wall of the through hole on the boiler body. The soot removal pipe 2 is positioned and connected to the inner wall of the through hole through the annular buffer block 4.
[0045] It should be noted that since the output end of the ash removal pipe 2 penetrates through the boiler body 1, even if the buffer component 3 offsets most of the force during the ash removal process, a rigid collision will still occur between the ash removal pipe 2 and the boiler body 1, potentially damaging the ash removal pipe 2 or the boiler. Therefore, this embodiment provides an annular buffer block 4 fitted around the outer periphery of the ash removal pipe 2. Specifically, the annular buffer block 4 is fixedly connected to the ash removal pipe 2 and also serves to limit the movement of the ash removal pipe 2. Simultaneously, the annular buffer block 4 prevents the ash removal pipe 2 from directly contacting the boiler body 1. Furthermore, during the ash removal process, the annular buffer block 4 provides cushioning, avoiding a rigid collision between the ash removal pipe 2 and the inner wall of the boiler. In specific implementations, the annular buffer block can be made of rubber.
[0046] The annular buffer block 4 in this invention also serves as a seal, preventing gas or dust from leaking out of the boiler body 1 during normal use or during ash removal.
[0047] Furthermore, the annular buffer block 4 is provided with a protrusion 41, and the through hole on the boiler body 1 is provided with a corresponding slot. The protrusion 41 cooperates with the slot to limit the rubber block. Understandably, this design prevents the annular buffer block 4 from shifting.
[0048] In this invention, both the buffer component 3 and the annular buffer block 4 buffer the ash cleaning pipe 2 during the ash cleaning process, and also prevent the ash cleaning pipe 2 from directly contacting the inner wall of the boiler, thereby preventing damage to the device.
[0049] In a specific embodiment of this utility model, the thermal power plant boiler acoustic wave return also includes a housing 5, which is used to be fixedly connected to the outer peripheral wall of the boiler body 1. The housing 5 is covered outside the buffer assembly 3, and the two ends of the slide rod 34 are fixedly connected to the housing 5 through fixing rods 8 respectively.
[0050] It should be noted that the housing 5 in this utility model is used to protect the buffer assembly 3. At the same time, the housing 5 has an opening on the side near the cleaning pipe 2 to prevent the cleaning pipe 2 from directly contacting the housing 5.
[0051] In one specific embodiment of this utility model, a fixing plate 6 is provided on the side of the shell 5 near the outer peripheral wall of the boiler. The fixing plate 6 is fixedly connected to the outer peripheral wall of the boiler body 1, and the shell 5 is fixedly connected to the fixing plate 6.
[0052] It should be noted that the fixing plate 6 can be connected to the boiler body 1 with screws or by riveting. By setting the fixing plate 6, it is easy to fix the shell 5 to the boiler body 1.
[0053] In one specific embodiment of this utility model, a dustproof net 7 is detachably connected to one end of the ash removal pipe 2 located in the inner cavity of the boiler body 1. Specifically, the ash removal pipe 2 and the dustproof net 7 are threaded together, which facilitates installation and disassembly. At the same time, the dustproof net 7 can prevent a large amount of dust from entering the ash removal pipe 2 during the ash removal process, thereby preventing the ash removal pipe 2 from becoming blocked.
[0054] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
