[0002] Air compressor equipment is a common gas compression equipment in daily work. Air compressor equipment in the prior art is mostly composed of an air intake pipeline, an air compressor and an exhaust pipeline. The air enters the air compressor through the air intake pipeline for primary compression. After the primary compression, the air enters the air compressor again through the elbow for secondary compression, and is finally discharged by the air compressor. After the two-stage compression, the gas flow rate, pressure and temperature increase sharply, resulting in a significant increase in noise and temperature on the exhaust side of the air compressor. During the use of the air compressor, the high-pressure airflow will make a huge noise when it is discharged at the end of the air compressor system. At the same time, the temperature of the gas rises sharply after compression.

[0003] Although current air compressors are equipped with silencers for noise reduction, most of the current silencers reduce noise by setting sound-absorbing materials on the gas flow path. The structure is too simple and cannot fully achieve the noise reduction effect. In addition, the prior art also lacks a structure that matches the gas cooling. The air compressor equipment has been operating under high temperature and high sound conditions for a long time, which greatly damages the reliability of the air compressor.

[0028] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present utility model will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0029] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0030] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0031] In order to solve the problem that the air compressor equipment in the prior art has poor noise reduction effect and lacks a cooling structure resulting in poor reliability, the utility model provides an air compressor equipment, which is used to achieve gas compression.

[0032] Specifically, Figure 1 As shown, the air compression equipment includes an air compressor 80, a temperature reduction and noise reduction device and a connecting pipeline. The exhaust end of the air compressor 80 is connected to the open end of the air intake pipe 20 of the silencer component of the temperature reduction and noise reduction device through the connecting pipeline.

[0033] After the gas flowing through the air compressor 80 is compressed in two stages, the flow rate and pressure of the gas discharged from the air compressor 80 increase sharply, so that the discharged gas is a high-temperature and high-noise gas.

[0034] It is understandable that the main reason for the high exhaust noise of the air compressor 80 is the high gas flow rate.

[0035] This embodiment provides a cooling and noise reduction device, and adopts a silencer component and a liquid cooling component to cool and reduce the noise of the gas discharged from the air compressor 80, which can greatly reduce the impact of the high temperature and high sound of the gas discharged from the air compressor 80 on the surrounding environment.

[0036] In this embodiment, the air compression equipment further includes a filter, and the filter is arranged on the air inlet side of the air compressor 80 to provide filtered gas to the air compressor 80 .

[0037] like Figure 2As shown, the temperature reduction and noise reduction device provided in this embodiment includes a shell 10, a silencer assembly and a liquid cooling assembly. The silencer assembly includes an air intake pipe 20 with an opening at one end and an exhaust pipe 30 with an opening at one end. The open ends of the air intake pipe 20 and the exhaust pipe 30 are both arranged on the outside of the shell 10, and the other end of the exhaust pipe 30 is arranged inside the shell 10 and has an installation cavity 301. The other end of the air intake pipe 20 extends into the interior of the installation cavity 301, and a liquid storage cavity 230 and a plurality of exhaust structures 240 at least partially arranged inside the liquid storage cavity 230 are provided on the tube wall of the other end of the air intake pipe 20. The air intake pipe 20 is connected to the installation cavity 301 through the exhaust structure 240, and the liquid cooling assembly includes a liquid inlet pipe 60 and a liquid outlet pipe, and the liquid inlet pipe 60 and the liquid outlet pipe are respectively connected to the liquid storage cavity 230.

[0038] Specifically, the temperature reduction and noise reduction device of this embodiment uses a silencer component and a liquid cooling component to achieve the gas entering the installation cavity 301 of the exhaust pipe 30 through the intake pipe 20. Due to the setting of the exhaust structure 240, the gas flows from the intake pipe 20 into the installation cavity 301, thereby reducing the flow rate of the gas, which is conducive to achieving the effect of noise reduction. Since the inner diameter of the installation cavity 301 is larger than the diameter of the intake pipe 20, the gas flows through the exhaust structure 240 and enters the installation cavity 301. The gas flow rate slows down, thereby achieving the first level of noise reduction treatment for the gas.

[0039] In this embodiment, the liquid storage chamber 230 is provided to cool the gas flowing through the exhaust structure 240 by adding a liquid cooling medium inside the liquid storage chamber 230, thereby achieving a cooling effect. At the same time, during the process of the gas flowing through the exhaust structure 240, the liquid cooling medium can play a certain role in reducing noise, thereby achieving a second level of noise reduction.

[0040] The liquid cooling medium may be water.

[0041] The temperature reduction and noise reduction structure proposed in this embodiment can effectively reduce the temperature and noise of high-pressure and high-speed gas.

[0042] The structure in which one end of the intake pipe 20 and the exhaust pipe 30 is open refers to a structure in which one of the two ends of the intake pipe 20 and the exhaust pipe 30 is open and the other end is closed. It can be understood that the end refers to the end along the length direction of the intake pipe 20 and the exhaust pipe 30.

[0043] In this embodiment, one end of the liquid inlet pipe 60 is connected to the liquid storage chamber 230 and the other end extends to the outside of the shell 10 and is connected to the liquid supply structure of the liquid cooling medium, wherein the liquid supply structure of the liquid cooling medium can be a water tank; one end of the liquid outlet pipe 70 is connected to the liquid storage chamber 230 and the other end extends to the outside of the shell 10 and is connected to the collection device of the liquid cooling medium, wherein the collection device of the liquid cooling medium can be a water tank.

[0044] like Figure 2As shown, the air inlet pipe 20 and the exhaust pipe 30 extend in the same direction. Along the extending direction of the air inlet pipe 20 , the opening ends of the air inlet pipe 20 and the exhaust pipe 30 are respectively arranged on both sides of the housing 10 .

[0045] Specifically, along the extension direction of the intake pipe 20, the two sides of the outer shell 10 have a first mounting hole and a second mounting hole, and the open end of the exhaust pipe 30 extends out of the outer shell 10 through the second mounting hole, and the other end of the exhaust pipe 30 has a third mounting hole connected to the mounting cavity 301, and the other end of the intake pipe 20 passes through the first mounting hole and the third mounting hole in sequence and extends into the interior of the mounting cavity 301.

[0046] The air inlet pipe 20 is supported at the first mounting hole and the third mounting hole to be fixed to the housing 10 , and the exhaust pipe 30 is supported at the second mounting hole to be fixed to the housing 10 .

[0047] In one implementation of the present embodiment, the air intake pipe 20 and the exhaust pipe 30 are coaxially arranged. The structural arrangement of the air intake pipe 20 and the exhaust pipe 30 coaxially arranged is conducive to improving the fluidity of the gas, thereby avoiding the occurrence of additional noise.

[0048] In this embodiment, the diameter of the open end of the intake pipe 20 is smaller than the diameter of the open end of the exhaust pipe 30, and the internal flow velocity of the gas in the larger diameter is smaller than the internal flow velocity in the lower diameter. Therefore, in this embodiment, the diameter of the intake pipe 20 is smaller than the diameter of the exhaust pipe 30, thereby reducing the flow velocity of the gas and achieving the effect of noise reduction.

[0049] In this embodiment, the diameter of the open end of the exhaust pipe 30 is smaller than the inner diameter of the installation cavity 301. Specifically, the inner diameter of the installation cavity 301 is D1, and the diameter of the other end of the intake pipe 20 is D2, D1 is N times D2, and 1≤N≤5. The larger the inner diameter of the installation cavity 301, the lower the flow rate of the gas, and the higher the pressure inside the installation cavity 301. Based on this, in order to avoid damage to the exhaust pipe 30 due to excessive pressure, the value of N is between 1 and 5, that is, N can be 1, 2, 3, 4 or 5.

[0050] like Figure 2 As shown, the exhaust structure 240 has an exhaust channel 241 , the exhaust channel 241 and the liquid storage chamber 230 are independently provided, and the air inlet pipe 20 is connected with the installation chamber 301 through the exhaust channel 241 .

[0051] Among them, the other end of the intake pipe 20 is formed into a porous tube structure by setting multiple exhaust structures 240, and the exhaust structure 240 forms an exhaust channel 241, so that the interior of the intake pipe 20 can be discharged into the interior of the installation cavity 301 through the multiple exhaust channels 241.

[0052] Specifically, independently arranged exhaust passage 241 and liquid storage chamber 230 are used to avoid leakage of liquid and gas.

[0053] In this embodiment, the plurality of exhaust structures 240 are arranged at equal intervals along the circumference of the intake pipe 20; alternatively, the plurality of exhaust structures 240 are arranged at equal intervals along the axial direction of the intake pipe 20; of course, the plurality of exhaust structures 240 are arranged at equal intervals along the circumference and axial direction of the intake pipe 20. The arrangement of the plurality of exhaust structures 240 can be adaptively arranged according to the exhaust requirements.

[0054] It can be understood that the diameter of the exhaust channel 241 is d, the extended length is l, and the number of the exhaust channels 241 is a, then the heat dissipation area is increased by a·πd·l, and the heat dissipation efficiency is improved by the increased heat dissipation area.

[0055] like Figure 2 As shown, the other end of the intake pipe 20 has an inner pipe wall 210 and an outer pipe wall 220 , a liquid storage chamber 230 is formed between the inner pipe wall 210 and the outer pipe wall 220 , and an exhaust structure 240 is disposed between the inner pipe wall 210 and the outer pipe wall 220 .

[0056] Specifically, a liquid storage cavity 230 of a sandwich structure is formed between the inner tube wall 210 and the outer tube wall 220 . The interior of the liquid storage cavity 230 is used to store a liquid cooling medium, and heat exchange with high-temperature gas flowing through the exhaust structure 240 is achieved through the liquid cooling medium.

[0057] Furthermore, the exhaust structure 240 used in this embodiment is a connecting column, and the inner tube wall 210 and the outer tube wall 220 are connected by the connecting column. By using the connecting column arranged between the inner tube wall 210 and the outer tube wall 220 to connect the inner tube wall 210 and the outer tube wall 220, the connecting column plays a role of connection and fixing, which is conducive to increasing the stability of the connection between the inner tube wall 210 and the outer tube wall 220.

[0058] The structure of the connecting column can be a cylindrical structure or a rectangular column structure, and the specific structure can be adaptively set according to needs.

[0059] In this embodiment, the exhaust structure 240 extends radially along the intake pipe 20, and the radially extending exhaust channel 241 is conducive to reducing the path of gas circulation, facilitating the gas to flow from the intake pipe 20 into the interior of the installation cavity 301 as quickly as possible, thereby achieving a noise reduction effect.

[0060] In this embodiment, the distance between the open end of the intake pipe 20 and the open end of the exhaust pipe 30 along the axial direction of the intake pipe 20 is L, and L satisfies 1m≤L≤4m. The longer the pipe length, the greater the flow resistance of the gas, and the higher the gas temperature, resulting in an insignificant cooling effect of the gas. When the total length of the pipe satisfies 1m≤L≤4m, it is beneficial to improve the cooling and noise reduction effect.

[0061] like Figure 2 As shown, the end of the installation cavity 301 that faces the opening of the exhaust pipe 30 forms a constricted structure.

[0062] Specifically, the exhaust pipe 30 includes a first pipe section 310, a transition pipe section 320 and a second pipe section 330 which are arranged in sequence along the axial direction. The first pipe section 310 forms a mounting cavity 301. One end of the transition pipe section 320 is connected to the first pipe section 310. The other end of the transition pipe section 320 is connected to the second pipe section 330 after being reduced. The transition pipe section 320 is formed into a spherical structure with the center of the sphere located on one side of the mounting cavity 301. The end of the second pipe section 330 which is away from the first pipe section 310 is the open end of the exhaust pipe 30.

[0063] The transition pipe section 320 is formed into a constricted structure to reduce the diameter of the second pipe section 330 , and the transition pipe section 320 is formed into an arc-top structure, and the guide surface of the arc-top structure is used to guide the airflow to improve the smoothness of the gas flow.

[0064] In this embodiment, the first pipe section 310 with a larger diameter is used to form the installation cavity 301 to achieve the first level of noise reduction for high-noise gas. The noise-reduced gas flows to the transition pipe section 320 and the second pipe section 330 and is then discharged.

[0065] like Figure 2 As shown, the silencer assembly also includes a sleeve structure 40 and a sound insulation member 50. The sleeve structure 40 is annular and is arranged inside the installation cavity 301. The sleeve structure 40 extends in the same direction as the intake pipe 20. Along the extension direction of the sleeve structure 40, the first end of the sleeve structure 40 is connected to the end plate of the other end of the exhaust pipe 30. The second end of the sleeve structure 40 is opened and connected to the exhaust pipe 30. The sleeve structure 40 has a plurality of sound holes 410 connected to the inner cavity of the sleeve structure 40. The other end of the intake pipe 20 is arranged inside the sleeve structure 40. The gas inside the intake pipe 20 enters the inner cavity and flows toward the exhaust pipe 30. The sound insulation member 50 is sleeved on the sleeve structure 40 and blocks the sound holes 410. The sleeve structure 40 abuts against the inner wall surface of the installation cavity 301 through the sound insulation member 50.

[0066] Among them, the sound insulation member 50 is sleeved on the sleeve structure 40 to cover the sound hole 410. The high-noise gas contacts the sound insulation member 50 through the sound hole 410. The sound insulation member 50 can achieve the effect of reducing noise. Since the sound insulation member 50 blocks the sound hole 410, there will be no air leakage. By setting the matching structure of the sleeve structure 40 and the sound insulation member 50, the third level of noise reduction treatment of the high-noise gas can be achieved. The gas after noise reduction flows from the open end of the sleeve structure 40 to the inside of the exhaust pipe 30.

[0067] Furthermore, one end of the sleeve structure 40 is an open end and the other end is connected to the end plate of the exhaust pipe 30, so that the other end of the sleeve structure 40 is a closed structure. The setting of the sleeve structure 40 is conducive to the unidirectional flow of gas and helps to improve the flow efficiency of the gas.

[0068] Furthermore, the opening of the sleeve structure 40 is rectangular or circular.

[0069] In this embodiment, the sound insulation member 50 is sound insulation cotton or a sound insulation board, wherein the sound insulation board is made of polyester fiber material.

[0070] In the present embodiment, the high-noise and high-temperature gas discharged from the air compressor 80 first flows into the intake pipe 20, and flows to the inner cavity of the sleeve structure 40 through the porous tube structure of the intake pipe 20. The gas flow rate in the inner cavity of the sleeve structure 40 slows down to achieve noise reduction. When the gas flows through the exhaust channel 241, the liquid cooling medium has a noise reduction effect on the noise propagation path; at the same time, the liquid cooling medium can cool the high-temperature gas inside the exhaust channel 241; the gas inside the sleeve structure 40 contacts the sound insulation component 50 through the sound hole 410, thereby achieving noise reduction. The gas after noise reduction flows into the exhaust pipe 30 and is then discharged. The cooling and noise reduction structure of the present embodiment adopts a triple noise reduction and a single cooling setting, which greatly improves the cooling and noise reduction of the high-temperature and high-noise gas discharged from the air compressor 80.

[0071] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0072] The temperature reduction and noise reduction device of the present application adopts a silencer component and a liquid cooling component to enable the gas to enter the installation cavity 301 of the exhaust pipe 30 through the intake pipe 20. Due to the setting of the exhaust structure 240, the gas flows from the intake pipe 20 into the installation cavity 301, thereby reducing the flow rate of the gas, which is conducive to achieving the noise reduction effect.

[0073] The present application sets a liquid storage chamber 230 to achieve cooling of the gas flowing through the exhaust structure 240 by adding a liquid cooling medium inside the liquid storage chamber 230, thereby achieving a cooling effect. The cooling and noise reduction structure proposed in the present application can effectively reduce the temperature and noise of high-pressure and high-speed gas.

[0074] The temperature reduction and noise reduction structure of the present application adopts a triple noise reduction and single temperature reduction setting, which greatly improves the temperature reduction and noise reduction of the high-temperature and high-noise gas discharged from the air compressor 80.
