Description

Technical Field

[0001] This utility model belongs to the technical field of marine mufflers, and in particular relates to exhaust smoke removal mufflers for low-resistance marine internal combustion engines. Background Technology

[0002] Marine silencers are auxiliary equipment for the exhaust pipes of generators, main engines, fuel-fired boilers, and fire-fighting diesel engines in ships. Their function is to eliminate the noise of exhaust during equipment operation and to extinguish any sparks remaining in the exhaust pipes.

[0003] When marine silencers are used on internal combustion engines, the main fuel used by these engines is diesel. Therefore, when the internal combustion engine is working, it will produce a certain amount of smoke. Since the smoke contains harmful substances, and the existing silencers do not have the function of filtering the smoke, it will cause certain harm to the health of the crew on board.

[0004] To address these issues, we offer a low-resistance marine internal combustion engine exhaust smoke removal and silencer. Utility Model Content

[0030] 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 skilled in the art without creative effort are within the protection scope of the present utility model. Specific Implementation Example 1

[0032] Please see Figure 1-8This utility model relates to an exhaust smoke removal muffler for a low-resistance marine internal combustion engine, comprising a muffler body 1, a fixing structure 4, and a filter structure 5. An intake pipe 2 is connected to the left side of the bottom of the muffler body 1, and an exhaust pipe 3 is connected to the right side of the top of the muffler body 1. The fixing structure 4 includes a fixing ring 401 and a locking block 403. The bottom of the fixing ring 401 is fixedly connected to the muffler body 1. The locking block 403 is disposed in the inner cavity of a fixing shell 402. Fixing shells 402 are fixedly connected to the front and rear sides of the top of the fixing ring 401. Two fixing shells 402 are located on opposite sides of each other. Each side is fixedly connected with a limiting rod 404. The two limiting rods 404 extend through to the outside of the fixed shell 402 and are fixedly connected with a pull block 405 on the side away from the locking block 403. A first spring 406 is provided on the surface of the limiting rod 404. The two sides of the first spring 406 are fixedly connected to the locking block 403 and the inner wall of the fixed shell 402 respectively. The filter structure 5 includes an outer shell 501, a filter bag 502 and an inner shell 503. A pressure block 504 is fixedly connected to the bottom of the front and rear sides of the outer shell 501. The top of the pressure block 504 is movably connected to the locking block 403.

[0033] Specifically: The intake pipe 2 on the muffler body 1 draws the exhaust gas from the internal combustion engine into the interior for noise reduction. The reduced exhaust gas is then discharged through the exhaust pipe 3 of the muffler body 1. Subsequently, the exhaust gas is discharged through the outer shell 501, filter bag 502, and inner shell 503. The filter bag 502 filters the exhaust gas, and the outer shell 501 and inner shell 503 further reduce the noise of the discharged exhaust gas. When the staff needs to clean the filter bag 502, they pull the pull block 405 to both sides. The pull block 405 then pulls the locking block 403 through the limit rod 404. The locking block 403 squeezes the first spring 406, causing the locking block 403 to separate from the pressure block 504. At this point, the staff can remove the outer shell 501 and clean the filter bag 502 and inner shell 503. Specific Implementation Example 2

[0035] Please see Figure 1-8Based on the first specific embodiment, positioning blocks 407 are fixedly connected to both sides of the locking block 403. A sliding rod 408 is slidably connected to the inner cavity of the positioning block 407. The front and rear sides of the sliding rod 408 are fixedly connected to the inner wall of the fixing shell 402. Positioning shells 409 are fixedly connected to the front and rear sides of the top of the fixing ring 401. A positioning rod 507 is engaged in the inner cavity of the positioning shell 409. The side of the positioning rod 507 near the outer shell 501 is fixedly connected to the outer shell 501. A second spring 410 is movably connected to the bottom of the positioning rod 507. The bottom of the silencing body 501 is fixedly connected to the inner wall of the positioning shell 409. Six limiting blocks 505 are fixedly connected to the bottom of the surface of the inner shell 503. Six slots 506 are opened at the bottom of the inner cavity surface of the outer shell 501. The inner cavity of the slots 506 is engaged with the surface of the limiting blocks 505. The inner cavity of the filter bag 502 is movably connected to the surface of the inner shell 503. The inner cavity of the outer shell 501 is movably connected to the surface of the filter bag 502. Six connecting blocks 6 are fixedly connected to the surface of the silencer body 1. A sound-absorbing cover 7 is fixedly connected between the six connecting blocks 6 on the side away from the silencer body 1.

[0036] Specifically: the use of positioning block 407 and sliding rod 408 ensures the stability of the locking block 403 during operation. The use of positioning shell 409 and positioning rod 507 ensures that when the outer shell 501 moves downward, the positioning rod 507 will enter the inner cavity of the positioning shell 409, thereby limiting the outer shell 501. The use of second spring 410 ensures that when the pressure block 504 is disengaged from the limiting of the locking block 403, the second spring 410 can lift the outer shell 501, making it easier for the operator to remove the outer shell 501. The use of locking groove 506 and limiting block 505 ensures that the inner shell 503 and the outer shell 501 can be effectively locked together, forming an installation space for the filter bag 502. The use of connecting block 6 fixes the silencer cover 7, which can further eliminate the residual sound on the silencer body 1.

[0037] The working principle of this utility model is as follows: the exhaust gas from the internal combustion engine is drawn into the muffler body 1 through the intake pipe 2 for noise reduction, and the reduced exhaust gas is discharged through the exhaust pipe 3 of the muffler body 1. Subsequently, the exhaust gas is discharged through the outer shell 501, the filter bag 502, and the inner shell 503. The filter bag 502 filters the exhaust gas, and the outer shell 501 and the inner shell 503 further reduce the noise of the discharged exhaust gas. When the staff needs to clean the filter bag 502, the staff pulls the pull block 405 to both sides. Then, the pull block 405 pulls the locking block 403 through the limiting rod 404. The locking block 403 squeezes the first spring 406, causing the locking block 403 to separate from the pressure block 504. At this time, the staff can remove the outer shell 501 and clean the filter bag 502 and the inner shell 503.
