[0002] To address the shortcomings of existing technologies, this utility model provides an acoustic sootblower with an easy-to-replace filter screen. This solves the problem in industrial production fields such as thermal power plants, cement plants, and steel plants, where numerous large pieces of equipment generate large amounts of dust during operation. Taking boilers as an example, after long-term operation, dust easily accumulates on their heating surfaces and flues, reducing heat transfer efficiency, increasing energy consumption, and potentially causing safety hazards. Acoustic sootblowers, as a commonly used ash removal device, play a crucial role in these environments. However, existing acoustic sootblowers have shortcomings in filter screen replacement under complex industrial environments. Traditional sootblower filters often use complex fixing methods, which easily lead to clogging and damage under harsh conditions such as high temperature, high dust, and strong corrosion. Regular replacement is necessary, but the process is cumbersome, often requiring professionals to use various tools and spend considerable time disassembling numerous components to access the filter screen. This is not only inefficient but also causes prolonged equipment downtime, affecting production continuity. In kiln systems, the difficulty in replacing filters and the long maintenance cycle prevent sootblowers from effectively cleaning accumulated ash in a timely manner, thus affecting normal combustion and production efficiency, and increasing production costs.

[0021] 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.

[0022] Please see Figure 1-5This utility model provides a technical solution: an acoustic soot blower with easy filter replacement, including a frame 1, an air inlet pipe 2 fixedly connected to the inner wall of the bottom of the frame 1, an acoustic tube 3 fixedly connected to the inner wall of the frame 1, a balance tube 6 fixedly connected to the inner wall of the frame 1 on the side away from the acoustic tube 3, a balance tube 6 fixedly connected to the inside of the frame 1, a membrane 7 fixedly connected to the inner wall of the frame 1, and also includes: a replacement device 5, the replacement device 5 including an anti-detachment device 51, a connecting rod 52 fixedly connected to the outer wall of the anti-detachment device 51, a push-out device 53 fixedly connected to the outer wall of the connecting rod 52, a fixing device 54 snapped onto the outer wall of the push-out device 53, and a filter screen 4 slidably connected to the inner wall of the push-out device 53;

[0023] The ejection device 53 includes a wrapping ring 531. A positioning cylinder 532 is fixedly connected to the outer wall of the bottom of the wrapping ring 531. A compression spring 533 is fixedly connected to the outer wall of the bottom of the positioning cylinder 532. An ejection rod 534 is fixedly connected to the bottom end of the compression spring 533. The bottom end pushes the ejection rod 534 upward, thereby pushing the filter screen 4, which has a rigid outer ring. Since the ejection rod 534 passes through the inside of the compression spring 533 and is slidably connected to the positioning cylinder 532, and the positioning cylinder 532 and the wrapping ring 531 are inserted into the inner wall of the acoustic tube 3, When the push rod 534 moves upward, it not only pushes the filter up but also compresses the spring 533 and drives the connecting rod 52 connected to it to move upward. This, in turn, pulls the magnetic plate 513 to slide upward along the limiting rod 512. During the movement of the magnetic plate 513, the connecting rod 514 rotatably connected to it rotates to both sides and separates, causing the sliding ring 515 to move away from the movement path of the filter screen 4. At this time, the push rod 534 continues to move upward, pushing the circular filter screen 4 with a hard ring edge upward, making it easy to remove from the acoustic tube 3.

[0024] The outer wall of the push rod 534 is fixedly connected to the outer wall of the connecting rod 52, the outer wall of the positioning cylinder 532 is inserted into the inner wall of the acoustic tube 3, the outer wall of the wrapping ring 531 is inserted into the inner wall of the acoustic tube 3, the push rod 534 is slidably connected to the inner wall of the positioning cylinder 532, and the outer wall of the diaphragm 7 is in contact with the outer wall of the acoustic tube 3.

[0025] The anti-detachment device 51 includes a fixed plate 511. A limiting rod 512 is fixedly connected to the outer wall of the top of the fixed plate 511. A magnetic plate 513 is slidably connected to the outer wall of the limiting rod 512. A connecting rod 514 is symmetrically rotatably connected to the outer wall of the magnetic plate 513. A sliding ring 515 is rotatably connected to the end of the connecting rod 514 away from the magnetic plate 513. The side wall of the fixed plate 511 is fixedly connected to the outer wall of the frame 1. The end of the magnetic plate 513 away from the connecting rod 514 is fixedly connected to the outer wall of the connecting rod 52. The outer wall of the sliding ring 515 is slidably connected to the outer wall of the wrapping ring 531. When the new filter screen is aligned with the installation position inside the acoustic tube 3, the new filter screen 4 is pushed down. At the same time, due to the action of the compression spring 533, the push rod 534, which loses its upward pushing force, is pushed down. The magnetic plate 513 moves down and is attracted to the fixed plate 511 because the top of the fixed plate 511 is magnetic. At this time, the connecting rod 514 drives the sliding ring 515 to move closer to each other and cover the top outlet of the filter screen 4.

[0026] The fixing device 54 includes a fixing block 541, a damping rod 542 fixedly connected to the inner wall of the fixing block 541, a compression spring 543 sleeved on the outside of the damping rod 542, a slider 544 fixedly connected to the end of the damping rod 542 away from the fixing block 541, a snap-fit ​​block 545 fixedly connected to the outer wall of the slider 544, the outer wall of the top of the fixing block 541 fixedly connected to the side wall outside the acoustic tube 3, the side wall of the fixing block 541 fixedly connected to the outer wall of the frame 1, one end of the compression spring 543 fixedly connected to the outer wall of the slider 544, and the other end of the compression spring 543 fixedly connected to the inner wall of the fixing block 541. The outer wall of 41 is slidably connected to the outer wall of slider 544, the outer wall of snap-fit ​​block 545 is snapped to the outer wall of positioning cylinder 532, the fixing block 541 in fixing device 54 is fixed to acoustic tube 3 and frame 1, the damping rod 542 is sleeved with compression spring 543, the slider 544 and snap-fit ​​block 545 connected at its end are snapped to the outer wall of positioning cylinder 532, when positioning cylinder 532 moves down, it squeezes snap-fit ​​block 545, which drives slider 544 to compress compression spring 543, when positioning cylinder 532 reaches the snap-fit ​​position, snap-fit ​​block 545 moves towards positioning cylinder 532 under the elastic force of compression spring 543 and snaps into positioning cylinder 532.

[0027] When in use, this sonic soot blower, which facilitates filter replacement, relies on the coordinated work of multiple functional components to achieve effective soot blowing and convenient filter replacement. The frame 1 provides stable support for the entire device and integrates key components such as the air inlet pipe 2, sonic tube 3, balance pipe 6, and diaphragm 7. The air inlet pipe 2 is responsible for introducing compressed air. The air flows through the frame 1 and moves within the sonic tube 3, interacting with the diaphragm 7 to generate sound waves. The balance pipe 6 assists in regulating the airflow and assists in resetting the diaphragm 7, ensuring stable sound wave output and stable soot blowing effect. The filter 4 is designed to be circular with a hard ring at the edge for easy subsequent installation and replacement.

[0028] When the filter screen 4 needs to be replaced, the replacement device 5 comes into play, pushing the push rod 534 upward from the bottom, thereby pushing the filter screen 4 with a hard outer ring. Since the push rod 534 passes through the inside of the compression spring 533 and is slidably connected to the positioning cylinder 532, and the positioning cylinder 532 and the wrapping ring 531 are inserted into the inner wall of the acoustic tube 3, when the push rod 534 moves upward, it will not only push it up, but also squeeze the compression spring 533 and drive the connecting rod 52 connected to it to move upward, thereby pulling the magnetic plate 513 to slide upward along the limiting rod 512. During the movement of the magnetic plate 513, the connecting rod 514 rotatably connected to it will rotate and separate to both sides, so that the sliding ring 515 moves away from the movement path of the filter screen 4. At this time, the push rod 534 continues to move upward, pushing the round filter screen 4 with a hard edge upward, making it easy to remove from the acoustic tube 3, thus completing the filter screen disassembly.

[0029] When installing the new filter 4, the operation process is reversed. Align the new filter with the installation position inside the acoustic tube 3 and push the new filter 4 downward. At the same time, due to the action of the compression spring 533, the push rod 534, which loses its upward pushing force, is pushed downward. The magnetic plate 513 moves down and is attracted to the fixed plate 511 because the top of the fixed plate 511 is magnetic. At this time, the connecting rod 514 drives the sliding ring 515 to move closer to each other and cover the top outlet of the filter 4, thereby preventing the filter 4 from falling off.

[0030] The positioning cylinder 532 interacts with the fixing device 54. The fixing block 541 in the fixing device 54 is fixed to the acoustic tube 3 and the frame 1. The damping rod 542 is fitted with a compression spring 543. The slider 544 and the locking block 545 connected to its end are locked to the outer wall of the positioning cylinder 532. When the positioning cylinder 532 moves down, it squeezes the locking block 545, which causes the slider 544 to compress the compression spring 543. When the positioning cylinder 532 reaches the locking position, the locking block 545 moves towards the positioning cylinder 532 under the elastic force of the compression spring 543 and locks the positioning cylinder 532. This, together with the limiting of the replacement device 5 by the acoustic tube 3, keeps the position of the filter screen 4 stable.

[0031] During normal use, the soot blower can operate stably and effectively remove accumulated dust from the equipment. When replacing the filter, the replacement device 5 makes the operation simple, saving time and labor costs. The anti-detachment device 51 ensures stable connection of components during the replacement process, and the fixing device 54 ensures that the filter is firmly installed, extending the service life of the filter and thus improving the reliability of the entire sonic soot blower.
