Technical Field
[0001] This utility model relates to the field of silencer technology, specifically a modular silencer for generator sets. Background Technology
[0002] A silencer is a noise reduction device used in airflow ducts that simultaneously transmit noise. It utilizes pipes with sound-absorbing linings, bends, or pipes with sudden changes in cross-sectional area or other discontinuous acoustic impedance to attenuate or reflect noise back into the duct. The former is called a resistive silencer, the latter a reactive silencer, and there are also composite impedance silencers.
[0003] Traditional generator mufflers are usually integrated welded structures. Some large generator mufflers are large in size and heavy in weight, requiring a lot of space during transportation and increasing transportation costs. Moreover, when the internal muffler components are damaged, the entire muffler needs to be disassembled for repair, which is cumbersome and results in long generator downtime, affecting work efficiency. Therefore, a modular muffler for generator sets is proposed. Utility Model Content

Example
[0020] Please see Figure 1-5This utility model provides a technical solution: a modular muffler for generator sets, including a muffler housing 1, a sound-absorbing component inside the muffler housing 1, and modular components installed at both ends of the muffler housing 1.
[0021] By setting up modular components and a muffler assembly, maintenance can be performed without complete disassembly, saving time and effort, avoiding excessive generator downtime and reducing work efficiency. Furthermore, the modular structure facilitates transportation and reduces muffler transport costs. The modular component includes a first connecting seat 3, a second connecting seat 4, and two second flanges 5. The first connecting seat 3 is installed at one end of the muffler housing 1, and the second connecting seat 4 is installed at the other end of the muffler housing 1. The two second flanges 5 are respectively fixedly connected to the opposite ends of the first connecting seat 3 and the second connecting seat 4. A first connecting cylinder 6 is fixedly connected to one side of a second flange 5. A through hole 7 is opened on the outer side of the first connecting cylinder 6. A first positioning plate 8 is fixedly sleeved on the outer side of the first connecting cylinder 6. Several first conduits 9 are installed on the first positioning plate 8. A first flange 2 is fixedly connected to both ends of the outer side of the silencer housing 1. The first flange 2 matches the two second flanges 5. Gas then enters the interior of the first connecting cylinder 6, the through hole 7 and the first conduit 9, where the gas is contracted, energy is consumed to silence it, and the silenced gas is discharged through the first connecting seat 3. The silencing assembly includes a first fixing plate 12, two expansion tubes 13, and a second fixing plate 14. The first fixing plate 12 is installed inside the muffler housing 1. Both expansion tubes 13 are fixedly connected to one side of the first fixing plate 12. The second fixing plate 14 is fixedly connected to the end of the expansion tubes 13 away from the first fixing plate 12. A fixing assembly is provided on the inner side of the muffler housing 1, located on one side of the first fixing plate 12. A third conduit 16 is fixedly connected to the first fixing plate 12, and a second conduit 15 is fixedly connected to the second fixing plate 14. The second conduit 15 and the third... The three conduits 16 and the two expansion tubes 13 are arranged alternately; the gas enters the expansion chamber inside the muffler housing 1 through the second connecting seat 4 and the second connecting cylinder 10 to achieve noise reduction. The gas enters the inner side of the first fixed plate 12 and the second fixed plate 14 through the expansion tube 13 and the third conduit 16, which can achieve the effect of noise reduction. Moreover, the holes on the outside of the expansion tube 13 can scatter the sound waves, which can achieve the effect of noise reduction. At this time, the gas is discharged through one end of the two expansion tubes 13 and the second conduit 15 and re-enters the internal expansion chamber of the muffler housing 1 to achieve the effect of noise reduction. The fixing assembly includes a limiting ring 17 and two fixing bolts 18. The limiting ring 17 is fixedly connected to the inside of the muffler housing 1 and located on one side of the limiting ring 17. The two fixing bolts 18 pass through the first fixing plate 12 and the second fixing plate 14 in sequence. One end of the two fixing bolts 18 is threaded to one side of the limiting ring 17. A second connecting cylinder 10 is fixedly connected to one end of a second flange 5. A second positioning plate 11 is fixedly sleeved on the outside of the second connecting cylinder 10. The first positioning plate 8 and the second positioning plate 11 are matched with the inner side of the muffler housing 1 and abut against the inner side of the muffler housing 1. By disassembling the second flange 5 and then pulling the first connecting seat 3 to move it, the first positioning plate 8 is disengaged from the inside of the muffler housing 1. Then, the fixing bolts 18 are disassembled with tools so that one end of the fixing bolts 18 is disengaged from one side of the limiting ring 17. The second fixing plate 14 can then be pulled to move, and the muffler assembly can be disassembled. The working principle or structural principle is as follows: by connecting the second connecting seat 4 to the after-treatment equipment of the generator set, the gas enters the expansion chamber inside the muffler housing 1 through the second connecting seat 4 and the second connecting cylinder 10 for noise reduction. The gas enters the inner side of the first fixed plate 12 and the second fixed plate 14 through the expansion pipe 13 and the third conduit 16, which can achieve the effect of noise reduction. Moreover, the holes on the outside of the expansion pipe 13 can scatter the sound waves, which can also achieve the effect of noise reduction. At this time, the gas is discharged through one end of the two expansion pipes 13 and the second conduit 15, and re-enters the internal expansion chamber of the muffler housing 1 to achieve the effect of noise reduction. The gas then enters the interior of the first connecting cylinder 6, the through hole 7 and the first conduit 9, where the gas is contracted, consuming energy to reduce noise. The noise-reduced gas is then discharged through the first connecting seat 3.
[0022] When maintenance or replacement of the muffler assembly is required, the second flange 5 is disassembled, and the first connecting seat 3 is pulled to move, thereby causing the first positioning plate 8 to detach from the inside of the muffler housing 1. Then, the fixing bolt 18 is disassembled with a tool, so that one end of the fixing bolt 18 is disengaged from one side of the limiting ring 17. The second fixing plate 14 can then be pulled to move, and the muffler assembly can be disassembled. No overall disassembly is required, saving time and effort, avoiding excessive downtime of the generator set, which affects work efficiency. Moreover, the modular structure facilitates transportation and reduces the cost of transporting the muffler.
