Description

Technical Field

[0001] This utility model relates to the field of silencer technology, specifically a high-efficiency, low-resistance modular silencer. Background Technology

[0002] A silencer is an advanced noise control device. A modular silencer, on the other hand, has a modular internal sound-absorbing structure that allows for mass production and flexible combination and installation according to specific application requirements. Through its special internal structure and sound-absorbing materials, it can effectively reduce the noise generated when airflow or sound passes through, exhibiting high sound-absorbing performance. While achieving efficient noise reduction, it also ensures minimal pressure loss.

[0003] When in use, silencers are installed at both the air inlet and outlet. The inlet silencer inserts need to be installed vertically to ensure ventilation, while the outlet silencer inserts need to be installed at an angle to ensure effective noise reduction. Existing silencer inserts typically use an insert-type fixing method. Therefore, during production, the limiting plates inside the outer frame used for inserting the silencer inserts need to be welded at different angles, increasing production variability, reducing production efficiency, and failing to fully meet the actual needs of on-site construction. Therefore, a high-efficiency, low-resistance modular silencer is needed to solve the above problems. Utility Model Content

The support block is fixed to the side of the support plate by bolts, and the support strip is fixed to the side of the support block.

[0008] Furthermore, the position adjustment assembly also includes a rotating shaft and a waist hole. The rotating shaft is rotatably connected to the inner side wall of the outer frame, and one end of the limiting plate is fixed to the side of the rotating shaft. The waist hole is opened at the end of the limiting plate away from the rotating shaft, and the support rod is inserted into the waist hole.

[0009] Furthermore, the position adjustment component also includes a first through hole, which is located in the middle of the support block, and the support block is fixed to the support plate by bolts passing through the first through hole and the movable hole.

[0010] Furthermore, the muffler also includes a connecting plate, which is fixed to the other end of the outer frame away from the support rod.

[0011] Furthermore, the sound-absorbing insert has a modular structure, the plate is a perforated metal plate, and a fiberglass plate is fixed inside.

[0012] Furthermore, it also includes a positioning component, which includes a screw, a pressure plate, a second through hole, and a nut. The lower end of the screw is fixed to the upper end of the support block. The second through hole is opened in the middle of one end of the pressure plate and is sleeved on the screw.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-7 As shown, this utility model is a high-efficiency, low-resistance modular silencer, comprising:

[0029] The muffler includes an outer frame 10, a limiting plate 11, and a silencing insert 12. The limiting plate 11 is movably connected inside the outer frame 10, and the two ends of the silencing insert 12 are inserted between the two limiting plates 11.

[0030] The muffler also includes a connecting plate 13, which is fixed to the other end of the outer frame 10 away from the support rod 22;

[0031] The sound-absorbing insert 12 has a modular structure, with a perforated metal plate as the material and a fiberglass plate fixed inside.

[0032] The outer frame 10 serves a protective and isolation function, while the limiting plate 11 serves a supporting function, supporting the sound-absorbing insert 12. The sound-absorbing insert 12 adopts a modular structure, with the plate material being a micro-perforated metal plate and glass fiber installed inside, which has a high noise reduction and low resistance effect. The connecting plate 13 is used to connect the outer frame 10 to the mechanical equipment.

[0033] The position adjustment assembly includes a support rod 22, a support plate 23, a movable hole 24, a support block 25, and a support strip 26. The support rod 22 is fixed to one end of the inner side of the outer frame 10, and one end of the limiting plate 11 is sleeved on the support rod 22. The support plate 23 is fixed to one end of the outer frame 10. The movable hole 24 is opened in the middle of the support plate 23. The support block 25 is fixed to the side of the support plate 23 by bolts, and the support strip 26 is fixed to the side of the support block 25.

[0034] The position adjustment assembly also includes a rotating shaft 20 and a waist hole 21. The rotating shaft 20 is rotatably connected to the inner wall of the outer frame 10, and one end of the limiting plate 11 is fixed to the side of the rotating shaft 20. The waist hole 21 is opened at the end of the limiting plate 11 away from the rotating shaft 20, and the support rod 22 is inserted into the waist hole 21.

[0035] The position adjustment assembly also includes a first through hole 27, which is opened in the middle of the support block 25, and the support block 25 is fixed to the support plate 23 by bolts passing through the first through hole 27 and the movable hole 24.

[0036] The pivot 20 and the waist hole 21 facilitate the rotation of the limiting plate 11. The support rod 22 provides support and prevents the limiting plate 11 from shifting. The support plate 23 provides support. The movable hole 24 facilitates the insertion of bolts. The support block 25 serves as a connector. The support bar 26 is used to support the limiting plate 11. The first through hole 27 is used to insert bolts.

[0037] Working principle:

[0038] According to the sound insulation requirements on site, the limiting plate 11 is rotated around the pivot 20 to a suitable position, and the waist hole 21 moves relative to the support rod 22. The support strip 26 on the support block 25 is placed below the limiting plate 11. The bolt passes through the movable hole 24 on the support plate 23 and the first through hole 27 on the support block 25 and is tightened. At this time, the limiting plate 11 is fixed in the current position. Then, the sound-absorbing insert 12 is inserted in sequence.

[0039] This step enables the production of the muffler outer frame 10 to be standardized, and allows for on-site adjustment of straight and oblique arrangement, with more flexible angles to adapt to different muffler requirements.

[0040] Please see Figure 7 As shown, this embodiment, based on the above embodiment, further includes:

[0041] The positioning assembly includes a screw 30, a pressure plate 31, a second through hole 32, and a nut 33. The lower end of the screw 30 is fixed to the upper end of the support block 25. The second through hole 32 is opened in the middle of one end of the pressure plate 31 and is sleeved on the screw 30. The nut 33 is screwed on the screw 30 and is located above the pressure plate 31.

[0042] The two support bars 26 on the support block 25 are located at the lower ends of the upper and lower limit plates 11 of the sound-absorbing insert 12, and the pressure plate 31 is pressed against the upper end of the upper limit plate 11.

[0043] The screw 30 and nut 33 serve a fixing function, the pressure plate 31 is used to press the limiting plate 11 at the upper end of the silencer insert 12, and the second through hole 32 serves a connecting function, making it easy to put the pressure plate 31 onto the screw 30.

[0044] Working principle:

[0045] Adjust the position of the limiting plate 11, fix the support block 25, put the second through hole 32 of the pressure plate 31 onto the screw 30, so that one end of the pressure plate 31 presses against the limiting plate 11 above the upper end of the silencer insert 12, and tighten the nut 33.

[0046] This step can prevent the limiting plate 11 above the noise-reducing insert 12 from shaking due to equipment vibration, thereby affecting the stability of the noise-reducing insert 12.
