Description

Technical Field

[0001] This utility model relates to the field of dust removal equipment technology, specifically a multi-frequency adjustable acoustic dust remover. Background Technology

[0002] Multi-frequency adjustable acoustic soot removers are devices that clean dust based on the principle of acoustic vibration. By adjusting the frequency and amplitude of the sound waves, they can more efficiently remove dust, particulate matter, or stubborn deposits adhering to the internal and external surfaces of industrial equipment. Compared with traditional mechanical or chemical cleaning methods, acoustic cleaning is non-contact, non-destructive, and energy-efficient, and is widely used in the maintenance of equipment such as boilers, heat exchangers, and pipelines. However, existing acoustic cleaning equipment still has some shortcomings in terms of equipment protection, especially when the equipment is shut down or running for extended periods, as dust particles may have a negative impact on the internal components.

[0003] Patent CN219092977U discloses an acoustic dust cleaner, including a sound generator, a sound amplification tube, a mounting tube, and an equipment compartment wall. A drive motor and a winding reel are installed on the outer side of the equipment compartment wall, with a steel wire rope wound on the reel. A hollow conduit is inserted through the inner side of the equipment compartment wall. A limiting hole is opened at the upper right end of the sound amplification tube, and a baffle is movably installed within the limiting hole. The shape of the baffle matches the cross-sectional shape of the sound amplification tube. The steel wire rope passes through the conduit and connects to the upper end of the baffle. A U-shaped groove is provided at the lower right end of the sound amplification tube. The baffle cooperates with the groove. When the acoustic dust cleaner stops, the drive motor is started, driving the winding reel to release the steel wire rope, thereby causing the baffle to descend into the groove, sealing the opening of the sound amplification tube and preventing dust particles from entering the acoustic dust cleaner and causing damage to the equipment, thus providing good protection.

[0004] The aforementioned existing technology, when the acoustic cleaner stops, uses a baffle that descends into the recess of the sound-amplifying tube, effectively sealing the opening of the tube and preventing dust particles from entering the equipment, thus providing a certain degree of protection for the internal components. However, this technology still has significant shortcomings in long-term use: dust particles may accumulate in the recess and on top of the second magnet, causing the first and second magnets to not fully align, resulting in gaps. Dust particles may enter the sound-amplifying tube through these gaps. Furthermore, dust particles entering the sound-amplifying tube easily adhere to the surface of the dustproof mesh. The blockage of the dustproof mesh not only affects the propagation path of sound waves but may also significantly reduce the overall cleaning effect of the acoustic cleaner. In view of this, we propose a multi-frequency adjustable acoustic cleaner. Utility Model Content

[0005] The purpose of this invention is to provide a multi-frequency adjustable acoustic soot cleaner to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A multi-frequency adjustable acoustic wave cleaner includes a multi-frequency adjustable acoustic wave generator and a device chamber wall. The output end of the multi-frequency adjustable acoustic wave generator is equipped with a sound amplification tube. The multi-frequency adjustable acoustic wave generator is used to generate sound waves with adjustable frequency and amplitude. The sound waves are transmitted into the device through the sound amplification tube to achieve efficient removal of dust and deposits. The outer wall of the device chamber wall is provided with a first rectangular fixed tube and a lifting component. The lifting component is located directly above the first rectangular fixed tube. The right end of the sound amplification tube passes through the first rectangular fixed tube into the device. Glass wool is filled between the outer wall of the sound amplification tube and the inner wall of the first rectangular fixed tube to reduce noise. The right end of the sound amplification tube is provided with a sealing component. The sealing component is used to close its opening when the sound amplification tube stops working to prevent dust particles from entering the interior of the sound amplification tube and thus damaging the device. The closure includes a rectangular fixing plate fixedly connected to the right end of the outer wall of the sound tube. A rectangular sealing plate is provided on the right side of the rectangular fixing plate. The rectangular sealing plate closes the opening of the sound tube by sliding. Anti-detachment sliders are provided at the bottom left side of the rectangular sealing plate and near the front and rear ends. Anti-detachment grooves are provided on the right side of the rectangular fixing plate and near the front and rear sides. The two anti-detachment sliders are slidably connected in the two anti-detachment grooves to ensure that the rectangular sealing plate remains stable during movement and to prevent it from sliding off. A lifting ring is provided at the middle of the top of the rectangular sealing plate. The lifting ring is used to connect a steel wire rope to realize the lifting and lowering of the rectangular sealing plate. The lifting component includes a second rectangular fixed tube, which provides a channel for the operation of the wire rope. The second rectangular fixed tube is installed through the outer wall of the equipment compartment. A rectangular cover is detachably connected to the left side of the second rectangular fixed tube by bolts.

The circular block is slidably connected in the circular groove, and the inner diameter of the circular groove is larger than the width of the strip groove, thereby ensuring that the anti-detachment slider is always located in the anti-detachment groove, avoiding accidental detachment of the slider, and ensuring the stability of the rectangular sealing plate moving up and down.

[0010] Preferably, two triangular positioning blocks are provided on the right side of the rectangular fixing plate near the bottom, which are arranged symmetrically front to back. These blocks position the rectangular sealing plate as it moves downward, so that the rectangular sealing plate just closes the opening of the sound amplifier tube. When the bottom of the rectangular sealing plate abuts against the triangular positioning blocks, the left side of the rectangular sealing plate fits against the right end of the sound amplifier tube, thus achieving a reliable seal on the opening of the sound amplifier tube.

[0011] Preferably, a partition is provided inside the second rectangular fixed tube near the right end, and a rubber ring is provided through the right side of the partition. The steel wire rope passes through the rubber ring, and the rubber ring wraps around the steel wire rope to prevent dust particles from entering the space to the left of the partition and to prevent dust particles from adhering to the winding spool.

[0012] Preferably, a guide wheel is rotatably connected between the front and rear sides of the inner wall of the second rectangular fixed tube and near the right side of the partition. The steel wire rope passes around the guide wheel, which guides the movement path of the steel wire rope to ensure smooth operation and avoid jamming. A U-shaped clearance opening is provided on the right side of the bottom of the second rectangular fixed tube. When the steel wire rope drives the rectangular sealing plate to move up to the maximum height, the bottom of the rectangular sealing plate is located above the top of the right end of the sound amplifier tube, and the top of the rectangular sealing plate is in contact with the bottom of the second rectangular fixed tube. The U-shaped clearance opening is used to avoid the lifting ring.
