Description

Technical Field

[0001] This utility model relates to the technical field of fan silencers, specifically a movable and modular fan silencer. Background Technology

[0002] Fan silencers are a type of device that reduces noise from airflow passing through air ducts. The working principle of fan silencers is mainly to reduce long-wave and medium-wave noise by absorbing noise or refracting sound waves using porous sound-absorbing materials with different structures. They are used to reduce the aerodynamic noise generated by fans during operation and are widely used in construction, steel, petroleum, chemical, electronics, power generation, textile, papermaking and other fields.

[0003] According to the description in the patent application (authorization announcement number: CN 219865641 U) of a fan silencer, "This utility model discloses a fan silencer, including a pair of silencer housings, a set of sound-absorbing filling layers, a limiting filter frame, and an adjustable silencer mechanism. A housing flange connects the pair of silencer housings. A set of sound-absorbing filling layers is disposed inside the silencer housings, and a limiting filter frame is fitted on the side of the set of sound-absorbing filling layers away from the silencer housings. The adjustable silencer mechanism is disposed inside the silencer housings, and the adjustable silencer mechanism includes multiple sets of first sound-absorbing plates, and multiple sets of second sound-absorbing plates are provided on one side of the multiple sets of first sound-absorbing plates, and the multiple sets of first sound-absorbing plates and second sound-absorbing plates are staggered. This utility model, by staggering the multiple sets of sound-absorbing plates, can reduce the design size of the fan silencer while ensuring the sound absorption effect, thereby reducing the volume and weight of the fan silencer, reducing the manufacturing cost of the fan silencer, and improving the transportation convenience of the fan silencer."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model drives the transmission shaft to rotate by rotating the adjustment handle. The lifting screw rotates accordingly with the rotation of the transmission shaft under the cooperation of the drive pulley, synchronous belt, and double-groove transmission pulley. Multiple sets of first and second silencers move with the rotation of the lifting screw under the action of internal and external threads. In actual use, because the device is fixed by the flange opening and the silencer is large, multiple hole alignments are likely to occur during installation. It is also not suitable for use with fans of different sizes. In addition, the silencers are rigidly connected, and the noise will cause vibration, which will cause the silencers to resonate, affecting the performance. Therefore, it is necessary to improve the device to a movable and modular fan silencer to solve the above problems. Utility Model Content

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Example 1:

[0031] Based on the existing technology that uses flanged mounting for fixing, and the fact that the silencer is relatively large, leading to multiple misalignments during installation, and is unsuitable for use with fans of different sizes, this embodiment provides a movable, modular fan silencer. Please refer to [link / reference]. Figure 1-6 This utility model provides a technical solution: a movable combined fan silencer, including a silencer housing 1, a buffer pad 2 fixedly connected to the outside of the silencer housing 1, a sound-absorbing cotton filling layer 3 inside the silencer housing 1, an installation limiting mechanism 4 outside the silencer housing 1, and an auxiliary sound-absorbing mechanism 5 inside the silencer housing 1.

[0032] The installation limiting mechanism 4 includes an adjustment installation component 41 and a limiting component 42, with the limiting component 42 located outside the adjustment installation component 41.

[0033] Furthermore, the adjustment and installation assembly 41 includes a limiting frame 411, which is fixedly connected to the outside of the silencer housing 1. A slider 412 is slidably connected inside the limiting frame 411. A connecting bolt 413 is provided inside the slider 412.

A movable plate 416 is fixedly connected to one end of the first spring 415 near the slider 412. A locking block 417 is fixedly connected to one end of the movable plate 416 near the slider 412, which facilitates the adjustment of the position of the slider 412, thereby enabling the device to be installed and used with different fan outlets and increasing its applicability.

[0034] Furthermore, the movable plate 416 is slidably connected to the slide rod 414, and the corresponding positions of the limit frame 411 and the locking block 417 are provided with grooves, and the locking block 417 is in contact with the limit frame 411, which makes the installation process more stable.

[0035] Furthermore, the limiting component 42 includes a connecting platform 421, which is fixedly connected to the outside of the slider 412. A threaded rod 422 is rotatably connected inside the connecting platform 421. A limiting rod 425 is fixedly connected inside the connecting platform 421. A movable block 423 is slidably connected to the outside of the limiting rod 425. A contact limiting block 424 is fixedly connected to one end of the movable block 423 near the connecting bolt 413, which facilitates the adjustment of the position of the contact limiting block 424, thereby satisfying the abutment and limiting of the connected bolt 413 after installation, thus preventing the connected bolt 413 from loosening due to vibration during the use of the fan.

[0036] Furthermore, the movable block 423 is threadedly connected to the threaded rod 422, and the connecting platform 421 is provided with a groove at the corresponding position of the movable block 423. The movable block 423 is slidably connected inside the groove, and the contact limit block 424 contacts the connecting bolt 413, which facilitates a more stable limiting process.

[0037] Example 2:

[0038] Based on Embodiment 1, in the prior art, the sound-absorbing plate is rigidly connected. Since noise generates vibration, the sound-absorbing plate is prone to resonance, affecting its performance. Therefore, this utility model provides Embodiment 2 to solve the above-mentioned technical problem. Please refer to Embodiment 2. Figure 7-8 Furthermore, in conjunction with Embodiment 1, the auxiliary silencing mechanism 5 includes a connecting box 51, which is fixedly connected inside the muffler housing 1. A connecting block 52 is slidably connected inside the connecting box 51. A connecting frame 53 is fixedly connected to the end of the connecting block 52 away from the connecting box 51. A silencing plate 54 is fixedly connected inside the connecting frame 53. A sliding column 55 is fixedly connected inside the connecting box 51. A second spring 56 is fixedly connected inside the connecting box 51. A damping rod 57 is fixedly connected inside the connecting box 51. A sliding plate 58 is fixedly connected to the end of the damping rod 57 away from the connecting box 51. A first fixing block 59 is fixedly connected to the end of the sliding plate 58 away from the connecting box 51. A connecting rod 510 is rotatably connected inside the first fixing block 59. A second fixing block 511 is fixedly connected to the end of the connecting block 52 near the connecting rod 510. This facilitates the elimination of vibrations generated by the silencing plate 54, thereby increasing the effectiveness of the device.

[0039] Furthermore, the second spring 56 is fixedly connected to the slide plate 58, the slide plate 58 is slidably connected to the slide column 55, and the connecting rod 510 is rotatably connected to the second fixing block 511, which facilitates a more stable operation.

[0040] In actual operation, when this device is used, the operator first moves it to the designated installation position on the fan. The operator then pulls the movable plate 416. The movement of the movable plate 416, in conjunction with the first spring 415, causes the locking block 417 to move. This, in turn, causes the sliding block 412 to move, thus moving the connecting bolt 413. The connecting bolt 413 then completes the installation and positioning of the device with the fan. After installation, the operator rotates the threaded rod 422. This rotation, in conjunction with the limiting rod 425, causes the movable block 423 to move, thereby moving the contact limiting block 424 until it contacts the connecting bolt 413. The device is then then connected to the external air duct, etc. After connection, the set fan works, and with the buffer pad 2, the sound-absorbing cotton filling layer 3 and the sound-absorbing plate 54, the noise generated during the operation of the fan is eliminated by the refraction or absorption of the sound-absorbing plate. When the sound-absorbing plate 54 moves under the action of wind, the movement of the sound-absorbing plate 54, in conjunction with the connecting frame 53, causes the connecting block 52 to slide inside the connecting box 51, thereby causing the second fixed block 511 to move. In conjunction with the connecting rod 510, the first fixed block 59 moves. In conjunction with the sliding column 55, the sliding plate 58 moves. In conjunction with the second spring 56 and the damping rod 57, the vibration of the sound-absorbing plate 54 caused by the noise generated by the fan is eliminated, thereby increasing the effectiveness of the device.
