Description

Technical Field

[0001] The invention belongs to the technical field of water-cooling silencer, and in particular relates to a water-cooling silencer for a diesel generator set. Background Art

[0002] As a common power generation equipment, diesel generator sets are widely used in many fields such as industrial production, construction, and emergency power supply. During its operation, the high-temperature and high-pressure gas generated by diesel combustion is discharged from the exhaust system. This process not only produces strong noise of more than 100 decibels, which seriously affects the working environment and the lives of surrounding residents, but also the exhaust gas temperature is usually around 500℃-700℃, carrying a large amount of heat energy. Traditional silencers mainly reduce noise through single methods such as resistive silencer and resistive silencer. Resistive silencers use structures such as sudden changes in the cross-section of the pipe or side-connected resonance cavities to reflect and interfere with sound waves during propagation, thereby reducing sound energy. However, this method has poor processing effect on medium and high frequency noise, and has poor adaptability to noise of complex frequencies. Resistive silencers rely on internally filled sound-absorbing materials, such as asbestos and mineral wool, to vibrate the air particles in the sound-absorbing materials through sound waves, converting sound energy into heat energy and consuming it. However, these sound-absorbing materials are prone to aging and failure in long-term high-temperature environments, resulting in a gradual decrease in the sound-absorbing effect.

[0003] In order to ensure a better silencing effect during use, the existing water-cooled silencer is generally provided with spiral protrusions inside the silencer cover to increase the silencing time. However, since the silencer cover is provided with a large number of protrusions, when the smoke and dust inside the silencer cover is cleaned later, dead angles will exist between adjacent protrusions, which will lead to incomplete smoke and dust cleaning, affecting the heat exchange efficiency and thus the silencing effect. In addition, the cleaned smoke and dust are always located inside the silencer cover and may eventually be discharged along with the gas, eventually causing pollution.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

A synchronization rod 322 is installed on the side wall of the screw sleeve 321. A scraper 323 is installed on the synchronization rod 322. The scraper 323 is slidably connected to the inner wall of the silencer 2. The screw shaft 32 can drive the synchronization rod 322 and the scraper 323 to move downward, and the scraper 323 slides on the inner wall of the silencer 2, so that the smoke and dust adsorbed on the surface can be cleaned.

[0024] The bottom plate 4 is mounted on the through hole 132, and a plurality of pairs of guide blocks 42 are mounted around the bottom plate 4. A limit rod 324 is mounted on the top of the guide block 42. The limit rod 324 is slidably connected to the synchronization rod 322. A feed opening 43 is mounted on the bottom plate 4 between the gaps of adjacent guide blocks 42. A blocking plate 431 is slidably arranged at the bottom of the feed opening 43, and a connecting frame 432 is mounted on the blocking plate 431. A synchronization shaft 433 is mounted on the connecting frame 432. A guide block 33 is mounted on the top of the synchronization shaft 433. An inclined surface 331 is provided on the guide block 33, and the inclined surface 331 is connected to the pressure rod 33 mounted at the bottom of the screw sleeve 321. 32 vertically corresponds to, when the scraper 323 slides to the bottom, the pressure rod 332 at the bottom of the screw sleeve 321 squeezes the inclined surface 331, so that the guide block 33 rotates as a whole, and the guide block 33 drives the synchronous shaft 433 and the connecting frame 432 to rotate. At this time, the baffle plate 431 at the end of the connecting frame 432 is separated from the discharge port 43, and the scraped waste can slide down into the discharge port 43 at this time, achieving the purpose of discharge. When it is reset later, the discharge port 43 is sealed again by the baffle plate 431, so that the smoke and dust will not be discharged outward along the exhaust pipe, thereby achieving the purpose of protecting the environment.

[0025] The heat exchange sleeve 5 is movably plugged into the side wall of the muffler 2, and the heat exchange sleeve 5 is in a broken line shape. Guide surfaces 51 are provided at both ends of the heat exchange sleeve 5, and the guide surfaces 51 are in an inclined state. The guide surfaces 51 correspond vertically to the scraper 323. The inner wall of the heat exchange sleeve 5 is provided with an exchange chamber 511, and the exchange chamber 511 is connected to the water cooling chamber 11. When the screw shaft 32 can drive the scraper 323 to move downward, the scraper 323 can clean the smoke and dust on the inner wall of the muffler 2, and the scraper 323 can squeeze the heat exchange sleeve 5 through the guide surface 51 to move, so that the heat exchange sleeve 5 can be retracted, ensuring that the scraper 323 can perform the cleaning operation normally. At the same time, the muffler 2 can drive the convex heat exchange sleeve 5 to rotate together, and then the cold water in the water cooling chamber can be stirred, so that the water temperature remains uniform, and the heat exchange operation is performed more efficiently, thereby further improving the cooling effect and the muffler effect.

[0026] like Figure 1 , Figure 2 and Figure 3As shown, in a specific embodiment, a water outlet pipe 111 and a water inlet pipe 112 are respectively installed on the water cooling cover 1, and the water outlet pipe 111 and the water inlet pipe 112 are respectively communicated with the internal chamber of the water cooling chamber 11, and the water outlet pipe 111 and the water inlet pipe 112 are respectively connected to the cooling system. The cooling system is a prior art, and the working principle is not repeated here. Water is injected into the water inlet pipe 112 through the pump body in the cooling system, and the water flows into the water cooling chamber 11, and the final water flow can be discharged from the water cooling chamber 11 along the water outlet pipe 111. The height of the water outlet pipe 111 is higher than the height of the water inlet pipe 112, which ensures that the water moves slowly upward from the bottom of the water cooling cover 1, and ensures that the water in the cold water chamber is full.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, further, a pair of vertical plates 12 are vertically installed at the bottom of the water-cooling hood 1, and the vertical plates 12 have a supporting effect. A bearing plate 121 is horizontally installed on the pair of vertical plates 12, and the bearing plate 121 increases the supporting surface. A plurality of pairs of reinforcing plates 122 are installed between the bearing plate 121 and the side walls of the vertical plates 12. The plurality of pairs of reinforcing plates 122 are triangular in shape, and the supporting strength is improved by the reinforcing plates 122. A plurality of pairs of mounting holes 123 are opened on the vertical plates 12 for facilitating later installation, and the bottom of the through hole 132 is covered with a collecting hood 13, and a mounting plate 131 is provided on the side wall of the collecting hood 13. The mounting plate 131 is screwed together with the water-cooling hood 1 by bolts, and the collecting hood 13 is convenient for collecting smoke and dust in the later stage.

[0028] Embodiment 2: Based on Embodiment 1, the difference between this embodiment and embodiment 1 is as follows: Figure 5 , Figure 6 and Fig.10 As shown, a pair of notches 21 are provided on the silencer 2, and a connecting plate 211 is vertically installed on each pair of notches 21, and the connecting plate 211 is connected to the inner wall of the silencer 2, and the ring 212 is rotatably arranged on the outer wall of the connecting plate 211, and the inner wall of the ring 212 is fitted with the side wall of the connecting plate 211. When the silencer 2 rotates, the ring 212 is stationary, ensuring that the air inlet pipe 213 and the air outlet pipe 214 connected to the ring 212 can be connected to the inner cavity of the silencer, and the sealing of the two can be ensured.

[0029] like Figure 5 and Figure 6As shown, in a specific embodiment, a driving shaft 31 is installed at the output end of the driving motor 3, the driving shaft 31 movably penetrates the water cooling cover 1, the driving shaft 31 is fixedly penetrated and connected with the muffler cover 2, the end of the driving shaft 31 is connected with the screw shaft 32, the end of the screw shaft 32 is installed with a fixing plate 326, and a limiting plate 325 is installed on the top of the limiting rod 324, and the size of the limiting plate 325 is larger than the size of the limiting rod 324. After the screw shaft 32 rotates, the limited screw sleeve 321 and the synchronous rod 322 slide downward along the limiting rod 324, wherein the limiting plate 325 on the top of the limiting rod 324 ensures that the screw sleeve 321 and the limiting plate 325 will not separate, and the fixing plate 326 ensures that the screw sleeve 321 and the screw shaft 32 will not separate, and when the synchronous rod 322 slides, the synchronous rod 322 drives the scraper 323 on the surface to slide down along the inner wall of the muffler cover 2.

[0030] like Figure 2 , Figure 3 , Figure 5 , Figure 7 , Figure 8 and Fig. 9 As shown, further, four brackets 41 are installed at the bottom of the bottom plate 4, and a horizontal plate 411 is installed at the bottom of each of the four brackets 41. The horizontal plate 411 is connected to the side wall of the through hole 132, and the above structure serves the purpose of support. A guide surface 421 is provided on the surface of the guide block 42, and the guide surface 421 is in an inclined state. The surface of the discharge port 43 is connected to the lowest point of the guide surface 421, and the size of the blocking plate 431 is adapted to the size of the guide surface 421. When the dust falls, it can fall onto the discharge port 43 through the guide surface 421, which is convenient for later discharge.

[0031] Embodiment 3: Based on Embodiment 2, the difference between this embodiment and the present embodiment is as follows: Figure 5 and Figure 7 As shown, the synchronous shaft 433 movably passes through the base plate 4, and a fixing seat 435 is rotatably installed on the side wall of the synchronous shaft 433. The fixing seat 435 is welded and arranged on the top of the base plate 4, and a torsion spring 434 is sleeved on the synchronous shaft 433. One end of the torsion spring 434 is clamped on the side wall of the fixing seat 435, and the other end is clamped on the base plate 4. The pressure rod 332 is in a broken line shape, and a guide ball 333 is installed at the end of the pressure rod 332. The guide ball 333 and the inclined surface 331 are adapted to each other. When the scraper 323 descends to the bottom, the pressure rod 332 at the bottom of the screw sleeve 321 moves downward, and the guide ball 333 at the end of the pressure rod 332 presses the inclined surface 331 of the guide block 33, so that the guide block 33 rotates as a whole, and the guide block 33 drives the synchronous shaft 433 to rotate on the fixing seat 435, thereby twisting the torsion spring 434, and the torsion spring 434 is used to facilitate the later reset operation.

[0032] like Figure 3 and Figure 4As shown, in a specific embodiment, a slide plate 52 is installed on the side wall of the heat exchange sleeve 5, and a slide rod 521 is installed inside the slide plate 52 so as to be movable and penetrated. A support platform 524 is installed on one end of the slide rod 521, and the support platform 524 and the side wall of the heat exchange sleeve 5 are welded to each other, and a positioning plate 522 is installed on the other end of the slide rod 521. The diameter of the positioning plate 522 is larger than the diameter of the slide rod 521, and a return spring 523 is sleeved on the slide rod 521. One end of the return spring 523 is clamped on the positioning plate 522, and the other end is clamped on the side wall of the slide plate 52. When the heat exchange sleeve 5 slides outward, the slide plate 52 of the side wall slides along the slide rod 521 at this time, and the distance between the slide plate 52 and the positioning plate 522 becomes smaller, thereby compressing the return spring 523, and facilitating the subsequent return operation through the return spring 523.

[0033] The implementation principle of a water-cooled muffler for a diesel generator set of the present invention is as follows: When the device is in use, the operator needs to connect the air inlet pipe 213 with the exhaust pipe of the diesel generator set, and then inject water into the water inlet pipe 112 through the pump body in the cooling system, and the water flows into the water cooling chamber 11, and the final water flow can be discharged from the water cooling chamber 11 along the water outlet pipe 111.

[0034] When the exhaust gas enters the inner wall of the silencer 2 through the air inlet pipe 213, the outer wall of the silencer 2 and the water cooling chamber 11 are interconnected at this time, and the exhaust gas inside the silencer 2 can be cooled by the heat exchange operation. In addition, since a heat exchange sleeve 5 is installed inside the silencer 2, the heat exchange range is increased by the heat exchange sleeve 5, so that the heat exchange is more thorough, and the exhaust gas temperature drops more. In addition, the heat exchange sleeve 5 is a zigzag line, so that the gas itself is guided to flow along the zigzag line direction inside the silencer 2. Finally, the gas in the center of the silencer 2 can be mixed with the gas in the outer layer, and finally the gas heat exchange inside the silencer 2 is ensured to be more uniform, and finally discharged to the outside through the exhaust pipe 214, so as to achieve the purpose of silencing.

[0035] Among them, when the temperature of the exhaust gas drops, the pressure decreases synchronously, and the decrease in temperature and pressure will slow down the flow rate of the exhaust gas, and the movement of the gas molecules will be relatively smooth, thereby reducing the noise generated by the high-speed flow and rapid expansion of the gas. After the vibration of the sound wave is transmitted to the water-cooling chamber 11 filled with water, the water molecules vibrate synchronously, and the energy of the sound wave will be consumed through the vibration and friction of the water molecules, thereby achieving the purpose of reducing noise.

[0036] When the water cooling silencer reaches a certain level, the dust and particles on the exhaust gas will adhere to the inside of the silencer cover 2. At this time, the operator can start the drive motor 3, and the drive motor 3 drives the drive shaft 31 to rotate, and the drive shaft 31 can drive the screw shaft 32 to rotate, and the screw shaft 32 can also drive the silencer cover 2 to rotate inside the water cooling chamber 11. The rotation of the silencer cover 2 can stir the water in the water cooling chamber 11, improve the heat exchange efficiency, and further improve the silencer effect.

[0037] After the screw shaft 32 rotates, the limited screw sleeve 321 and the synchronization rod 322 slide downward along the limiting rod 324, wherein the limiting plate 325 on the top of the limiting rod 324 ensures that the screw sleeve 321 and the limiting plate 325 will not separate, and the fixing plate 326 ensures that the screw sleeve 321 and the screw shaft 32 will not separate. When the synchronization rod 322 slides, the synchronization rod 322 drives the scraper 323 on the surface to slide down along the inner wall of the silencer 2, and the inner wall of the silencer 2 rotates, so that the dust on the inner wall of the silencer 2 can be scraped off, and the scraped dust automatically falls down, so that the shell of the silencer 2 is kept clean and the heat exchange can be carried out smoothly.

[0038] When the scraper 323 descends, the scraper 323 can squeeze the guide surface 51 on the surface of the heat exchange sleeve 5. At this time, as they squeeze each other, the heat exchange sleeve 5 begins to shrink outward along the silencer cover 2, so that the end face of the heat exchange sleeve 5 and the inner wall of the silencer cover 2 fit each other, which is convenient for the scraper 323 to clean it. After the heat exchange sleeve 5 moves outward, the heat exchange sleeve 5 moves into the water cooling chamber 11, and the silencer cover 2 can drive the protruding heat exchange sleeve 5 to rotate together. At this time, the heat exchange sleeve 5 is equivalent to a stirring plate, which can stir the cold water in the water cooling chamber 11, so that the water temperature remains uniform and the heat exchange operation is performed more efficiently.

[0039] When the heat exchange sleeve 5 slides, the slide plate 52 of the side wall slides along the slide rod 521, and the distance between the slide plate 52 and the positioning plate 522 becomes smaller, thereby compressing the reset spring 523, and the reset operation is facilitated by the reset spring 523.

[0040] When the scraper 323 drops to the bottom, the pressure rod 332 at the bottom of the screw sleeve 321 moves downward, and the guide ball 333 at the end of the pressure rod 332 presses the inclined surface 331 of the guide block 33, so that the guide block 33 rotates as a whole, and the guide block 33 drives the synchronous shaft 433 to rotate on the fixed seat 435, thereby twisting the torsion spring 434, and the torsion spring 434 is used to facilitate the later reset operation. When the synchronous shaft 433 rotates, the synchronous shaft 433 drives the connecting frame 432 to rotate. At this time, the blocking plate 431 at the end of the connecting frame 432 is separated from the discharge port 43, and the scraped waste can slide down along the guide surface 421 into the discharge port 43, and then fall into the inside of the collecting cover 13, and the waste collection operation is completed through the collecting cover 13, and then the above structure is reset by reversing the driving motor 3, and the water cooling and silencing operation is performed again.
