Description

Technical Field

[0001] This utility model belongs to the field of silencer technology, specifically a heat-insulating silencer. Background Technology

[0002] A silencer is a device used to reduce or attenuate airflow noise. It is widely used in various machinery, equipment, and piping systems to reduce noise pollution to the environment and human health.

[0003] Chinese patent CN208267944U discloses an improved muffler heat insulation structure, including a muffler body with a support base at its bottom. A connecting pipe is fixedly installed on the side of the muffler body away from the support base. This improved muffler heat insulation structure facilitates the installation of the muffler body by setting a support base at its bottom and connecting it to other exhaust pipes by setting a connecting pipe on its top surface. By setting a partition plate inside the muffler body and using a double inner sealing plate, a space is left between the outer sealing plate and the inner sealing plate, and between the muffler body and the partition plate, for installing heat insulation cotton. This reduces the heat radiation generated during long-term use of the unit, reduces the impact of muffler heat radiation on the unit, and improves the overall service life of the unit.

[0004] In the existing technology, the aforementioned patent provides an improved muffler heat insulation structure, which utilizes the installation of heat insulation cotton to reduce the heat radiation generated during long-term use of the unit. This reduces the impact of muffler heat radiation on the unit and improves the overall service life of the unit. However, for construction machinery vehicles, which mainly use diesel engines, a large amount of noise is generated during operation. At the same time, the exhaust gas flow rate is large, the pressure is high, and the gas temperature is very high. In this case, using heat insulation cotton for heat insulation will affect the discharge of a large amount of gas. In addition, the high pressure may directly blast open the heat insulation cotton, and the efficiency of use needs to be improved.

[0005] Therefore, a heat-insulating silencer is proposed to address the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies and solve the problems mentioned above for engineering machinery vehicles, which mainly use diesel engines and generate huge noise during operation, while also producing large flow rates, high pressures, and high temperatures of exhaust gas, using heat insulation cotton would affect the discharge of a large amount of gas, and the high pressure could also directly blast open the heat insulation cotton, thus requiring improved efficiency, a heat-insulating muffler is proposed.

[0007] The technical solution adopted by this utility model to solve its technical problem is as follows: The heat-insulating silencer of this utility model includes a cylinder, a first partition plate, and a second partition plate; the first partition plate and the second partition plate are arranged equidistantly inside the cylinder, and a first end cap and a second end cap are fixedly connected to both sides of the cylinder, respectively. A first cavity is formed between the surface of the first partition plate and the first end cap, a second cavity is formed between the surface of the first partition plate and the second partition plate, and a third cavity is formed between the second partition plate and the second end cap. An air inlet pipe passes through the inside of the cylinder and at the position of the first cavity, and an air outlet pipe passes through the inside of the cylinder and at the position of the third cavity. A first air guide pipe is fixedly connected to one side of the second partition plate, and the first air guide pipe passes through the first partition plate and extends into the first cavity. A second air guide pipe is fixedly connected to one side of the first partition plate, and the second air guide pipe passes through the second partition plate and extends into the third cavity.

[0008] Preferably, the surfaces of the first and second partitions are fixedly connected to the inner wall of the cylinder, and both the first and second air guide pipes are disposed in the second cavity.

[0009] Preferably, both ends of the air inlet pipe and the air outlet pipe are fixedly connected to a connecting flange and a plug, respectively, and an air outlet bracket is fixedly connected to the surface of the air outlet pipe located on the outer side of the cylinder.

[0010] Preferably, an arc-shaped placement plate is fixedly connected to the surface of the cylinder, and a support platform is fixedly connected to the surface of the arc-shaped placement plate.

[0011] Preferably, a storage platform is fixedly connected to the inner side of the support platform, and a condensate tank is snapped onto the top of the storage platform.

[0012] Preferably, both sides of the condensate tank are connected to condensate pipes, one end of which penetrates the cylinder. The portion of the condensate pipe located in the cylinder is S-shaped and is positioned above the first and second air guide pipes.

[0013] The beneficial effects of this utility model are:

[0014] This utility model provides a heat-insulating silencer. By setting multiple cavities, when gas enters the cylinder, it continuously expands, first eliminating some low- and mid-frequency noise, then eliminating some high-frequency noise, and finally eliminating some noise before being discharged. At the same time, as the gas continues to disperse, it gradually cools down. Overall, it achieves noise reduction while also providing heat insulation and heat dissipation, and ensuring stability during operation.

[0015] This utility model provides a heat-insulating silencer. By setting up a condensate tank, the internal condensate circulates inside the cylinder through a condensate pipe. When gas enters the second chamber, due to the high temperature, the gas rises and comes into contact with the condensate pipe, which can exchange heat and achieve a rapid cooling effect, thereby further improving the heat dissipation effect.

[0024] 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.

[0025] Specific implementation examples are given below.

[0026] Please see Figures 1-5This utility model provides a heat-insulating silencer, including a cylindrical body 1, a first partition 2, and a second partition 3. The first partition 2 and the second partition 3 are equidistantly arranged inside the cylindrical body 1. A first end cap 4 and a second end cap 5 are fixedly connected to both sides of the cylindrical body 1, respectively. A first cavity 6 is formed between the surfaces of the first partition 2 and the first end cap 4, a second cavity 7 is formed between the surfaces of the first partition 2 and the second partition 3, and a third cavity 8 is formed between the second partition 3 and the second end cap 5. An air inlet pipe 9 passes through the inside of the cylindrical body 1 at the position of the first cavity 6, and an air outlet pipe 10 passes through the inside of the cylindrical body 1 at the position of the third cavity 8. A first air guide pipe 11 is fixedly connected to one side of the second partition 3, passing through the first partition 2 and extending into the first cavity 6. A second air guide pipe 12 is fixedly connected to one side of the first partition 2, passing through the second partition 3 and extending into the third cavity. Inside the cylinder 1, during operation, gas is transferred, and noise reduction and heat dissipation are achieved. The airflow enters the cylinder 1 through the inlet pipe 9, and then dissipates from the holes on the surface of the inlet pipe 9 into the first cavity 6, where it expands and eliminates some low- and mid-frequency noise. Subsequently, the gas enters the second cavity 7 through the first guide pipe 11, where it expands and eliminates some high-frequency noise. Finally, it enters the third cavity 8 through the second guide pipe 12, where it expands again and eliminates some noise. Finally, the gas is discharged through the outlet pipe 10. By setting up multiple cavities, when the gas enters the cylinder 1, it continuously expands, first eliminating some low- and mid-frequency noise, then eliminating some high-frequency noise, and finally eliminating some noise before being discharged. At the same time, as the gas continues to disperse, it gradually cools down. The whole process achieves noise reduction, heat insulation and heat dissipation, and ensures stability during operation.

[0027] Furthermore, such as Figure 2 and Figure 4 As shown, the surfaces of the first partition 2 and the second partition 3 are fixedly connected to the inner wall of the cylinder 1. The first air guide pipe 11 and the second air guide pipe 12 are both located inside the second cavity 7. Connecting flanges 13 and plugs 14 are fixedly connected to both ends of the air inlet pipe 9 and the air outlet pipe 10, respectively. An air outlet support 15 is fixedly connected to the outer surface of the air outlet pipe 10 located inside the cylinder 1. During operation, the first partition 2 and the second partition 3 are fixed to the inner wall of the cylinder 1 to separate the three cavities and ensure sealing. Gas flows through both the first air guide pipe 11 and the second air guide pipe 12 within the second cavity 7. The connecting flange 13 is used to connect external pipes for easy air intake and exhaust. The air outlet support 15 supports the air outlet pipe 10.

[0028] Furthermore, such as Figure 3 and Figure 5As shown, an arc-shaped placement plate 16 is fixedly connected to the surface of the cylinder 1, and a support platform 17 is fixedly connected to the surface of the arc-shaped placement plate 16; a storage platform 18 is fixedly connected to the inner side of the support platform 17, and a condensate tank 19 is snapped onto the top of the storage platform 18; condensate pipes 20 are connected to both sides of the condensate tank 19, one end of the condensate pipe 20 penetrates the cylinder 1, the portion of the condensate pipe 20 located in the cylinder 1 is S-shaped, and the portion of the condensate pipe 20 located in the cylinder 1 is above the first air guide pipe 11 and the second air guide pipe 12. During operation, the arc-shaped placement plate 16 is attached to the cylinder 1 to support it. The support platform 17 supports the arc-shaped placement plate 16. The placement platform 18 is located inside the support platform 17 to support the installation of the condensate tank 19. The condensate tank 19 uses the condensate pipe 20 to circulate the condensate, which is then sent into the cylinder 1. The part of the condensate pipe 20 inside the cylinder 1 is higher than the first air guide pipe 11 and the second air guide pipe 12, which facilitates heat exchange with the rising gas. By setting up the condensate tank 19, the condensate inside circulates in the cylinder 1 through the condensate pipe 20. When the gas enters the second cavity 7, it rises due to the high temperature and comes into contact with the condensate pipe 20, where heat exchange occurs, thereby achieving a rapid cooling effect and further improving the heat dissipation effect.

[0029] First, gas is transported inside the cylinder 1 for noise reduction and heat dissipation. The airflow enters the cylinder 1 through the inlet pipe 9, then disperses through the holes on the surface of the inlet pipe 9 into the first cavity 6, where it expands and eliminates some low-to-mid frequency noise. Subsequently, the gas enters the second cavity 7 through the first guide pipe 11, where it expands and eliminates some high-frequency noise. Finally, it enters the third cavity 8 through the second guide pipe 12, where it expands again and eliminates some noise. Finally, the gas is discharged through the outlet pipe 10. By setting up multiple cavities, when the gas enters the cylinder 1, it continuously expands, first eliminating some low-to-mid frequency noise, then eliminating some high-frequency noise, and finally eliminating some noise before being discharged. At the same time, as the gas disperses, it gradually cools down. The whole process achieves noise reduction, heat insulation and heat dissipation, and ensures stability during operation. Subsequently, the first partition plate 2 and the second partition plate 3 are fixed on the inner wall of the cylinder 1 to separate the three cavities and ensure sealing. The first air guide pipe 11 and the second air guide pipe 12 both allow gas to flow in the second cavity 7. The connecting flange 13 is used to connect external pipes to facilitate air intake and exhaust. The air outlet bracket 15 supports the air outlet pipe 10. Finally, the arc-shaped placement plate 16 is attached to the cylinder 1 to support the cylinder 1. The support platform 17 supports the arc-shaped placement plate 16. The placement platform 18 is set inside the support platform 17 to support the installation of the condensate tank 19. The condensate tank 19 uses the condensate pipe 20 to circulate the condensate, thereby sending the condensate into the cylinder 1. The part of the condensate pipe 20 inside the cylinder 1 is higher than the first air guide pipe 11 and the second air guide pipe 12, which facilitates heat exchange with the rising gas. By setting up the condensate tank 19, the condensate inside circulates in the cylinder 1 through the condensate pipe 20. When the gas enters the second cavity 7, due to the high temperature, the gas will rise and come into contact with the condensate pipe 20, which can exchange heat and achieve a rapid cooling effect, thereby further improving the heat dissipation effect.
