Description

Technical Field

[0001] This utility model belongs to the field of exhaust system technology, and in particular relates to a diesel engine silent exhaust component. Background Technology

[0002] According to the published patent CN216894599U, an explosion-proof diesel engine exhaust assembly includes a booster pump, an exhaust pipe, and an exhaust gas treatment box. The booster pump is connected to both the exhaust end of the explosion-proof diesel engine and the intake end of the exhaust pipe. The exhaust end of the exhaust pipe is connected to the intake end of the exhaust gas treatment box. The exhaust pipe includes a first pipe and a second pipe. The exhaust pipe also includes a first guide plate and a second guide plate. This design solves the problem that traditional explosion-proof diesel engine exhaust pipes generally use a single double-layer pipe for heat dissipation, which can easily lead to turbulent water flow and poor heat dissipation during the heat dissipation process. However, it still has the following shortcomings: The aforementioned equipment improves the heat dissipation efficiency of the exhaust manifold upon completion. However, the muffler is crucial in the exhaust system. The muffler is typically fixed to the diesel engine connecting pipe using nuts and bolts. However, under long-term use, the nuts may loosen or even fall off due to vibration. This could affect the structural stability of the entire exhaust system, leading to component failure or damage and impacting the normal operation of the diesel engine. Therefore, we propose a diesel engine silent exhaust system. Utility Model Content

[0003] The purpose of this utility model is to provide a diesel engine silent exhaust assembly. Through the fixing mechanism and the purification mechanism, it solves the problem of improving the heat dissipation efficiency of the exhaust manifold when the above-mentioned equipment is completed. However, the muffler is crucial in the exhaust assembly. The muffler is generally fixed to the diesel engine connecting pipe by nuts and bolts. However, under long-term use, the nuts may loosen or even fall off due to vibration. This may affect the structural stability of the entire exhaust system, leading to the failure or damage of system components and affecting the normal operation of the diesel engine.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a diesel engine silent exhaust assembly, including a muffler, a connecting pipe fixedly connected to the bottom inner wall of the muffler, and a fixing mechanism provided on the outer wall of the connecting pipe; The fixing mechanism includes a flange, the inner wall of which is fixedly connected to the inner wall of the connecting pipe. A second flange is snapped onto the outer wall of the flange, and a second connecting pipe is fixedly connected to the inner wall of the second flange. Both the flange and the second flange have several threaded holes on their inner walls. Bolts are inserted into the inner walls of the several threaded holes, and nuts are threaded onto the outer walls of the several bolts. A sliding ring is slidably connected to the outer wall of the connecting pipe, and several fixing brackets are fixedly connected to the outer wall of the sliding ring. A purification mechanism is provided on the top inner wall of the silencer.

[0005] Furthermore, the outer walls of several of the fixing frames are in contact with the outer wall of the nut, and several sliding rods are fixedly connected to the outer wall of the sliding ring on the side away from the fixing frame, and a fixed shaft is slidably connected to the inner wall of several of the sliding rods.

[0006] Furthermore, a sleeve shaft is fixedly connected to the outer wall of the fixed shaft, springs are sleeved on the outer walls of several flanges, and the outer walls of several sleeve shafts are fixedly connected to the outer wall of the muffler.

[0007] Furthermore, the purification mechanism includes an exhaust pipe, the outer wall of which is fixedly connected to the top inner wall of the muffler, a fixing ring fixedly connected to the inner wall of the exhaust pipe, a plurality of mounting grooves being formed on the inner wall of the fixing ring, a slot being formed on the inner wall of each of the mounting grooves, an activated carbon filter plate being inserted into the inner wall of each of the mounting grooves, a plurality of insertion slots being formed on the inner wall of each of the insertion slots, an insertion box being inserted into the inner wall of each of the insertion boxes, and a lead screw being rotatably connected to the inner wall of each of the insertion boxes.

[0008] Furthermore, the inner walls of several of the plug-in boxes are fixedly connected with limit rods, the outer walls of several of the lead screws are threaded with sliding blocks, and the inner walls of several of the sliding blocks are slidably connected to the outer walls of the limit rods.

[0009] Furthermore, a fixing plate is fixedly connected to the inner wall of each of the plug-in boxes, a limiting shaft is slidably connected to the inner wall of each of the fixing plates, and a sliding groove is provided on the inner wall of each of the plug-in boxes.

[0010] Furthermore, spring 2 is sleeved on the outer wall of each of the limiting shafts, and the outer wall of the end of the limiting shafts near the fixed plate is slidably connected to the inner wall of the slide groove.

[0011] Furthermore, the outer wall of one end of several limiting shafts near the fixed plate engages with the inner wall of the slot, and the outer wall of one end of several limiting shafts away from the fixed plate contacts the outer wall of the sliding block.

[0012] This utility model has the following beneficial effects: 1. This utility model incorporates a spring, which releases the compressed spring and causes it to rebound. The rebound force of the spring drives the sliding rod to quickly reset, which in turn drives the sliding ring to quickly reset. When the sliding ring returns to its original position, the fixing bracket on the sliding ring contacts the nut, thus limiting and fixing the nut to prevent it from falling off due to vibration, which would otherwise result in poor venting.

[0013] 2. This utility model incorporates a second spring. When compressed, the second spring is released and rebounds. The rebound force of the second spring causes it to quickly reset. After resetting, the limiting shaft retracts the end that was originally stuck in the slot into the connector box, thus releasing the restriction on the activated carbon filter plate of the connector box. The connector box can then be pulled out of the slot, and the activated carbon filter plate, which was previously restricted, can be removed from the retaining ring for replacement. This achieves quick disassembly of the activated carbon filter plate, effectively preventing the accumulation of carbon deposits, oil stains, and other substances that affect the performance of the exhaust system, thereby improving the purification effect on flue gas.

[0014] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0018] 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.

[0019] Please see Figure 1-6As shown, this utility model is a diesel engine silent exhaust assembly, including a muffler 1. A connecting pipe 101 is fixedly connected to the inner wall of the bottom of the muffler 1. The muffler 1 is used to connect the muffler 1 to the diesel engine. A fixing mechanism 2 is provided on the outer wall of the connecting pipe 101. The fixing mechanism 2 includes a flange 201. The inner wall of the flange 201 is fixedly connected to the inner wall of the connecting pipe 101. A second flange 202 is snapped onto the outer wall of the flange 201. A second connecting pipe 203 is fixedly connected to the inner wall of the second flange 202. Several threaded holes 204 are opened on the inner walls of both the flange 201 and the second flange 202. The second flange 202 on the second connecting pipe 203 is aligned with the flange 201, and bolts 205 are connected to it through the threaded holes 204. Bolts 205 are inserted into the inner walls of the several threaded holes 204. Nuts 206 are threadedly connected to the outer walls of the several bolts 205. A sliding ring 207 is slidably connected to the outer wall of 01. Several fixed brackets 208 are fixedly connected to the outer wall of the sliding ring 207. A purification mechanism 3 is provided on the top inner wall of the muffler 1. The outer walls of the several fixed brackets 208 are in contact with the outer wall of the nut 206. Several sliding rods 209 are fixedly connected to the outer wall of the sliding ring 207 away from the fixed brackets 208. When the sliding ring 207 starts to move upward, it will drive the sliding rods 209 to move along the same trajectory. The inner walls of the several sliding rods 209 are slidably connected to a fixed shaft 210. The outer wall of the fixed shaft 210 is fixedly connected to a sleeve shaft 211. The outer walls of the several flanges 201 are all fitted with springs 213. When the sliding rods 209 start to move, they will slide on the fixed shaft 210. While sliding, they will compress the springs 213. The outer walls of the several sleeve shafts 211 are fixedly connected to the outer wall of the muffler 1. The purification mechanism 3 includes an exhaust pipe 301, which is used to discharge the exhaust gas generated by the diesel engine. The outer wall of the exhaust pipe 301 is fixedly connected to the inner wall of the top of the muffler 1. A fixing ring 302 is fixedly connected to the inner wall of the exhaust pipe 301. The inner wall of the fixing ring 302 has several mounting grooves 303, which are used for positioning subsequent parts. Each mounting groove 303 has a slot 304 on its inner wall, and an activated carbon filter plate 305 is inserted into each mounting groove 303. The activated carbon filter plate 305 is used to filter the exhaust gas generated by the diesel engine. This makes the exhaust gas purer. The inner wall of the activated carbon filter plate 305 is provided with several insertion slots 306. Insertion boxes 307 are inserted into the inner walls of the insertion slots 306. Lead screws 308 are rotatably connected to the inner walls of the insertion boxes 307. Limiting rods 309 are fixedly connected to the inner walls of the insertion boxes 307. Sliding blocks 310 are threadedly connected to the outer walls of the lead screws 308. When the lead screws 308 start to rotate, they will drive the sliding blocks 310 to slide downward on the limiting rods 309. The inner walls of the sliding blocks 310 are slidably connected to the outer walls of the limiting rods 309. A number of plug-in boxes 307 have fixed plates 311 fixedly connected to their inner walls. Each fixed plate 311 has a slidable limit shaft 312 slidably connected to its inner wall. Each plug-in box 307 has a sliding groove 314 on its inner wall. Each limit shaft 312 has a spring 313 fitted onto its outer wall. When the sliding block 310 moves a certain distance, it will no longer compress the limit shaft 312. At this time, the spring 313, which was originally compressed, will also be released. The limit shafts 312 then... One end of the outer wall of the fixed plate 311 is slidably connected to the inner wall of the slide groove 314. One end of the outer wall of several limiting shafts 312 near the fixed plate 311 is engaged with the inner wall of the slot 304. One end of the outer wall of several limiting shafts 312 away from the fixed plate 311 is in contact with the outer wall of the sliding block 310. The rebound force of the second spring 313 will drive the second spring 313 to quickly reset. After the reset, the limiting shaft 312 will retract the end that was originally engaged in the slot 304 into the plug box 307.

[0020] One specific application of this embodiment is: When the operator needs to use the equipment, first connect the connecting pipe 203 to the diesel engine. Then align the flange 202 on the connecting pipe 203 with the flange 201 and connect the bolts 205 through the threaded holes 204. Next, push the sliding ring 207 upward. When the sliding ring 207 starts to move upward, it will drive the sliding rod 209 to move along the same trajectory. When the sliding rod 209 starts to move, it will slide on the fixed shaft 210. While sliding, it will compress the spring 213. After the sliding rod 209 has moved a certain distance, tighten the nut 206 onto the bolts 205. After the nuts 206 are fully tightened, the upward-pushing sliding ring 207 is released, and the previously compressed spring 213 is released. The spring 213 then begins to rebound, and the rebound force of the spring 213 causes the sliding rod 209 to quickly return to its original position. The sliding rod 209 then causes the sliding ring 207 to quickly return to its original position. When the sliding ring 207 returns to its original position, the fixing bracket 208 on the sliding ring 207 contacts the nut 206, thus limiting and fixing the nut 206. When the diesel engine starts operating, exhaust gas is generated, and this exhaust gas will pass through the connecting pipe... 203 enters the silencer 1. The silencer 1 then uses a sudden change in the pipe cross-section to alter the acoustic impedance of the sound wave propagation, causing some of the sound waves to reflect back towards the sound source, reducing the energy propagating forward. The flue gas then continues to move upwards into the exhaust pipe 301, and is subsequently filtered by the activated carbon filter plate 305 before being discharged outwards. When the activated carbon filter plate 305 has been used for a long time, it needs to be replaced. At this time, the lead screw 308 is rotated. When the lead screw 308 starts to rotate, it drives the sliding block 310 to slide downwards on the limiting rod 309. When the sliding block 310 moves a certain distance, it will no longer press against the limiting shaft 312. The previously compressed spring 313 will be released and then spring back. The force of the spring's rebound will cause it to quickly reset. After resetting, the limiting shaft 312 will retract the end that was originally stuck in the slot 304 into the connector box 307. This releases the restriction on the activated carbon filter plate 305 of the connector box 307. Then, the connector box 307 can be pulled out from the connector slot 306, and the activated carbon filter plate 305 that was in contact with the restriction can be removed from the fixing ring 302 for replacement. When you want to install it, just repeat the above operation in the reverse direction.
