Description

Technical Field

[0001] The present application relates to the field of silencer structures, and in particular to a disc-shaped intubation silencer assembly and a compressor. Background Art

[0002] Among the noises generated by the compressor when it is running, aerodynamic noise accounts for the largest proportion. The aerodynamic noise of the compressor refers to the noise generated when the gas flows inside the compressor. The aerodynamic noise of the compressor is usually determined by factors such as the gas flow speed, pressure difference, geometry of the flow path and the internal structure of the compressor.

[0003] Among them, the noise generated by the compressor exhaust port is the most intense. When the compressor compresses the gas and then discharges it, the high-speed discharge and pressure release of the gas will cause noise.

[0004] One or more silencer chambers are set in a conventional muffler, allowing the gas discharged from the compressor to pass through the silencer chamber and then to the exhaust pipe. The setting of the silencer chamber will occupy a large space, and the connection between the silencer chamber and the exhaust pipe, as well as the changes in the size of the space in the silencer chamber and the space in the exhaust pipe may generate new noise, and even cause problems such as unsatisfactory noise reduction effect and reduced exhaust efficiency.

[0026] like Figure 1 to Figure 3 As shown, a disc-shaped plug-in silencer assembly is shown, which includes a silencer disc 1 and a plurality of silencer pipes 2. The silencer disc 1 has a relative air inlet side Y2 and an air outlet side Y1, and the plurality of silencer pipes 2 extend from the air inlet side Y2 to the air outlet side Y1.

[0027] like Figure 4 As shown, a compressor is shown, including the above-mentioned disc-shaped intubation type silencer assembly, wherein the disc-shaped intubation type silencer assembly also includes an exhaust pipe 4, and the exhaust pipe 4 is arranged on the air outlet side Y1 and covers a plurality of silencer pipes 2.

[0028] The exhaust pipe 4 is directly used to cover the silencer pipe 2 at the outlet side Y1, avoiding the need to set a chamber, making the design simpler and more compact, saving space, and improving exhaust efficiency. The combination of the silencer disc 1, the silencer pipe 2, and the exhaust pipe 4 is simple in structure, easier to maintain and replace, and reduces maintenance costs.

[0029] Furthermore, the compressor also includes: a compressor body, the compressor body has an exhaust port 6, the air inlet side Y2 is against the exhaust port 6, the silencer disk 1 and the exhaust port 6 are surrounded to form a first chamber X1, and a plurality of silencer pipes 2 are located at one end of the air inlet side Y2 and extend into the first chamber X1.

[0030] By starting the silencing process at the exhaust port 6, the noise directly radiated by the exhaust pipe 4 and the expansion joint can be effectively reduced, thereby reducing the overall noise level. Starting the silencing process at the exhaust port 6 can make the silencing effect more effective and avoid affecting the overall silencing effect due to the radiated noise of the exhaust pipe 4 or the expansion joint.

[0031] By moving the silencing process forward to the exhaust port 6, the length of the exhaust pipe 4 can also be reduced, thereby saving space, especially in space-constrained application scenarios. Silencing at the exhaust port 6 can reduce the need for subsequent silencing devices, thereby reducing the cost of the overall silencing system.

[0032] In a preferred embodiment, the windward area 11 is protruding. When installed, the windward area 11 is embedded in the exhaust pipe 4 to form a tighter seal to prevent exhaust leakage. The protruding windward area 11 can fit tightly with the inner wall of the exhaust pipe 4 to form a sealing ring, effectively preventing gas from leaking from the gap. The protruding windward area 11 can be easily installed in the exhaust pipe 4, and the installation process is simple and quick. The windward area 11 embedded in the exhaust pipe 4 can improve the structural stability of the exhaust pipe 4 and prevent the exhaust pipe 4 from loosening or falling off.

[0033] The convex setting of the windward area 11 can form a tighter seal and reduce the leakage of exhaust noise. Preventing exhaust leakage can improve the efficiency of the exhaust system, reduce energy loss, and effectively prevent gas from leaking from the gap between the exhaust pipe 4 and the compressor exhaust port 6, ensuring the normal operation of the exhaust system. Better sealing can extend the service life of the exhaust pipe 4 and the compressor and reduce maintenance costs.

[0034] like Figure 4 , Figure 5 and Figure 7 As shown, the exhaust pipe 4 is a bent pipe, and there is an angle between the pipe openings at both ends of the exhaust pipe 4. Several silencer pipes 2 are located at different distances from one end of the outlet side Y1 to the outlet side Y1. The silencer pipe 2 that protrudes the most from the outlet side Y1 is arranged close to the inner side of the bending direction of the exhaust pipe 4.

[0035] The exhaust pipe 4 is a curved pipe structure. On the one hand, it is to adapt to the existing compressor structure and save space. The curved pipe structure can flexibly adapt to the existing compressor structure without major changes to the compressor, saving space and facilitating installation. On the other hand, the curved exhaust pipe 4 changes the direction of the airflow, cooperates with the silencer disk 1 to achieve a noise reduction effect, and generates eddy currents and reflections when the airflow passes through the silencer disk 1, thereby effectively absorbing and attenuating the exhaust noise.

[0036] Furthermore, the distances between one end of the plurality of silencer pipes 2 located on the air intake side Y2 and the air intake side Y2 are the same.

[0037] Specifically, see Figure 5 As shown, the muffler pipe 2 protrudes from the air inlet side Y2 to form a lower end pipe 24, and the muffler pipe 2 protrudes from the air outlet side Y1 to form an upper end pipe. The distance from the lower end pipe 24 to the air inlet side Y2 is the same as L0, and the distance from the upper end pipe to the air outlet side Y1 is different. The upper end pipes that are far from the air outlet side Y1 are arranged close to the inner side of the bending direction of the exhaust pipe 4. The inner side here refers to the side close to the bending direction, such as Figure 7 Left side or Figure 4 on the right side of the .

[0038] The upper end tubes are arranged far from the gas outlet side Y1 and close to the inner side of the bending direction of the exhaust pipe 4, which can save space. Figure 4As shown, the inner side has a longer extension space to accommodate the longest upper end pipe, thereby avoiding increasing the size of the bending section of the exhaust pipe 4.

[0039] Furthermore, the gas discharged from the longest upper end pipe can enter the bending section of the exhaust pipe 4 earlier, and its discharge position, discharge frequency and discharge height are different from those of the gas discharged from the shorter upper end pipe, which will not cause resonance and can achieve better noise reduction effect.

[0040] In a preferred embodiment, the number of the silencer pipes 2 is three. Figure 5 As shown, the three silencer pipes 2 are respectively the first pipe 21 at the upper end, the second pipe 22 at the upper end, and the third pipe 23 at the upper end. The first pipe 21 at the upper end, the second pipe 22 at the upper end, and the third pipe 23 at the upper end have different heights. The heights of the first pipe 21 at the upper end, the second pipe 22 at the upper end, and the third pipe 23 at the upper end are L1, L2, and L3 respectively. The third pipe 23 at the upper end is arranged close to the inner side of the bending direction of the exhaust pipe 4.

[0041] According to the ratio of the internal gears of the compressor, the ratio of L1:L2:L3 is set to select the silencer disk 1 that best matches the compressor.

[0042] In a preferred embodiment, the diameters of the plurality of silencer pipes 2 are the same.

[0043] like Figure 2 and Figure 6 As shown, the central area of ​​the silencer disk 1 has a fixing frame 3, and the fixing frame 3 includes a horizontal portion 32 and a plurality of vertical portions 33. One ends of the plurality of vertical portions 33 are connected to the air outlet side Y1, and the other ends of the plurality of vertical portions 33 are connected to the horizontal portion 32. The horizontal portion 32 and the vertical portion 33 are recessed inward to form a recessed area 31, and each silencer pipe 2 is clamped in a recessed area 31.

[0044] Specifically, the recessed area 31 is arc-shaped and adapted to the edge of the silencer pipe 2 to provide a stable support. The silencer pipes 2 are all clamped in the recessed area 31 of the fixing frame 3 to form a stable support structure to prevent the silencer pipes 2 from shaking or falling off in the silencer disc 1. The stable support of the silencer pipe 2 can ensure that the airflow passes smoothly through the silencer cavity, avoids airflow disturbance and noise generation, and thus improves the silencing effect. The stable support structure can reduce the wear between the silencer pipe 2 and the silencer disc 1, and extend the service life of the silencer disc 1.

[0045] Furthermore, the recessed area 31 is adapted to the arc shape of the edge of the silencer pipe 2 to facilitate the installation and removal of the silencer pipe 2 and improve the installation efficiency. It can also make the silencer pipe 2 evenly stressed, avoid local stress concentration, and improve the strength and durability of the silencer pipe 2.

[0046] In a preferred embodiment, Figure 2As shown, the fixing frame 3 is flush with the uppermost tube.

[0047] In another preferred embodiment, Figure 5 As shown, the fixing frame 3 is shorter than the uppermost tube.

[0048] See also Figure 7 As shown, further, one end of the exhaust pipe 4 is connected to an outer edge portion 41, and the outer edge portion 41 extends outward from the outer edge of one end of the exhaust pipe 4. An annular mounting area 12 is formed on the outlet side Y1 of the muffler disc 1, and the outer edge portion 41 abuts against the mounting area 12. The provision of the outer edge portion 41 increases the contact area between the muffler disc 1 and the exhaust pipe 4, and can provide better air tightness.

[0049] See also Figure 4 As shown, further, the disc-shaped plug-in silencer assembly also includes: an annular flange 5, the exhaust pipe 4 is sleeved in the annular flange 5, the outer edge portion 41 is arranged between the annular flange 5 and the silencer disc 1, and an annular assembly area 13 is formed on the air outlet side Y1 of the silencer disc 1, the assembly area 13 is arranged outside the installation area 12, and the annular flange 5 and the silencer disc 1 are connected in the assembly area 13.

[0050] A positioning pin 121 is provided on the silencer disc 1, and a positioning hole matching the positioning pin 121 is provided on the exhaust port 6 of the compressor. The positioning pin 121 can accurately align the silencer disc 1 and the exhaust port 6 of the compressor, simplify the installation process, and reduce installation time and cost. The positioning pin 121 can ensure the installation accuracy of the silencer disc 1 and the exhaust port 6 of the compressor, and avoid affecting the noise reduction effect or system performance due to installation deviation. The positioning pin 121 can stably position the silencer disc 1 and the exhaust port 6 of the compressor to prevent components from loosening or falling off, and ensure the reliability and safety of the system.

[0051] The positioning pin 121 can also simplify the installation process, shorten the installation time, and reduce the installation cost. The positioning pin 121 can also improve the overall stability of the silencer disk 1 and the exhaust port 6 of the compressor, prevent the displacement or loosening of the components during operation, and extend the service life of the system. The provision of the positioning pin 121 can also facilitate subsequent maintenance and repair, avoiding troubles caused by installation deviation or loose components.

[0052] Furthermore, a mounting hole 122 is provided on the mounting area for connecting the exhaust pipe 4, the annular flange 5 and the exhaust port 6 of the compressor.

[0053] See also Figure 1 As shown, further, a windward area 11 is formed on the air inlet side Y2 of the silencer disc 1, and a plurality of silencer pipes 2 are arranged in the windward area 11 to form a ventilation area 20, and the area ratio of the ventilation area 20 to the windward area 11 is S2 / S1≥1 / 4.

[0054] Furthermore, the silencer disk 1 has a windward area 11, and the silencer disk 1 in the windward area 11 blocks the airflow from the air inlet side Y2 to the air outlet side Y1. A plurality of silencer pipes 2 are arranged in the windward area 11, and the silencer pipes 2 connect the air inlet side Y2 and the air outlet side Y1. The silencer pipes 2 have a ventilation area 20, and the area of ​​the windward area 11 on the air inlet side Y2 is a first area S1, and the sum of the areas of the ventilation areas 20 of all the silencer pipes 2 on the air inlet side Y2 is a second area S2, and the first area covers the second area, and S2 / S1≥1 / 4.

[0055] like Figure 1 As shown, the portion within the innermost dotted circle is the windward area 11, and the portion within the muffler 2 is the ventilation area 20. The windward area 11 includes the ventilation area 20 when calculating, that is, all areas within the innermost dotted circle are included in the windward area 11, so the first area covers the second area.

[0056] In addition, the windward area 11 is on the air inlet side Y2 of the silencer disk 1, and the size of the windward area 11 is the same as the size of the exhaust port 6. In a preferred embodiment, the size of the exhaust port 6 is the same as the size of the exhaust pipe 4, ensuring the consistency of the size of the airflow in and out of the space, thereby increasing the noise reduction effect.

[0057] The silencer 2 is provided to achieve silence. Obviously, the size of the silencer 2 is smaller than the windward area 11. The principle is to reduce noise by adjusting the speed and direction of gas flow. The smaller silencer 2 can cause changes in the speed and pressure of the gas, thereby changing the flow characteristics of the gas in the pipeline. When the gas passes through the smaller silencer 2, the gas flow rate increases and the pressure decreases. This change in speed and pressure can reduce the noise generated when the gas flows.

[0058] In addition, the smaller silencer pipe 2 can also change the direction of gas flow. By designing the shape and curvature of the silencer pipe 2, the gas flow can be guided to change direction, thereby reducing the propagation of noise. This operation of changing the flow direction can disperse and attenuate the noise energy and reduce the overall noise level.

[0059] Furthermore, the windward area 11 is used to prevent the gas from passing directly, thereby blocking the propagation path of the noise. The ventilation area 20 in the silencer 2 provides a prescribed passage, allowing the gas to circulate around the windward area 11. By reasonably setting the area ratio of the ventilation area 20 and the windward area 11, that is, S2 / S1≥1 / 4, the silencing effect can be further optimized and the noise generated at the engine exhaust port 6 can be reduced.

[0060] The disc-shaped plug-in silencer assembly consists of a silencer disc 1 and a silencer pipe 2, and has a relatively simple structure. The silencer disc 1 is used as a connecting component and is firmly fixed to the engine exhaust port 6. The silencer pipe 2 runs through the silencer disc 1 and forms a ventilation area 20, and the number and layout of the silencer pipe 2 can be adjusted according to specific needs. This simple and reliable structural design makes the silencer disc 1 easy to manufacture and install, and has high reliability and durability.

[0061] Furthermore, the ratio of the area of ​​the ventilation area 20 to the windward area 11, ie, S2 / S1, ranges from 25% to 30%.

[0062] By setting the range, a more accurate noise reduction effect can be achieved. It is worth noting that the ventilation area 20 is included when calculating the area of ​​the windward area 11, and the windward area 11 is the area on the muffler disc 1 including the muffler pipe 2 that blocks the flow of gas.

[0063] Specifically, in a preferred embodiment, the silencer plate 1 is made of a steel plate with a thickness of 5 mm, and the silencer plate 1 has a 100 mm 2 The windward area 11 is selected from the silencer pipe 2, and the sum of the areas is 15.9mm 2 , 25mm 2 、25.6mm 2 , 30mm 2 、44.4mm 2 Five sets of silencer discs 1 were tested, with an initial noise of 90dB (decibel). The results are shown in the following table.

[0064] S2 / S1 Noise after noise reduction Reduced noise 15.9％ 85dB 5dB 25.0％ 78dB 12dB 25.6％ 75dB 15dB 30％ 77dB 13dB 44.4％ 80dB 10dB

[0065] It can be seen from the above embodiments that when the ratio of the area of ​​the windward area 11 to the ventilation area 20 is within the range of 25% to 30%, the noise reduction effect is the best, and the noise can be reduced by 13dB to 15dB. When the ratio is higher than 30%, since the ventilation area 20 occupies a larger area of ​​the windward area 11, the noise reduction effect is not achieved. When the ratio is lower than 25%, pressure loss will occur. Since the gas is compressed into a very small pipe in a shorter time and space, not only will the noise reduction effect be greatly reduced, but sometimes even other noises will be generated, which will also have an adverse effect on the energy efficiency of the whole machine.

[0066] Furthermore, there are three silencer pipes 2 , which are distributed in an equilateral triangle and are located in the central area of ​​the silencer disk 1 .

[0067] When the ratio of the area of ​​the ventilation area 20 to the area of ​​the windward area 11 is set to 28%, the number of the silencer pipes 2 is tested, specifically, the values ​​of three silencer pipes 2 and four silencer pipes 2 are tested.

[0068] When the fan frequency on the top of the machine is 28HZ and the initial noise is 80.8dB, the results are as shown in the following table.

[0069] Number of silencer pipes Noise after noise reduction Reduced noise 3 silencer pipes 77.3dB 3.5dB 4 silencer pipes 77.5dB 3.3dB

[0070] The fan frequency at the top of the whole machine here is the frequency of a fan at the top of the compressor. By adjusting its frequency, the initial noise and air volume will be changed, thereby affecting the noise reduction effect.

[0071] When the fan frequency on the top of the machine is 30HZ and the initial noise is 81.3dB, the results are as shown in the following table.

[0072] Number of silencer pipes Noise after noise reduction Reduced noise 3 silencer pipes 77.4dB 3.9dB 4 silencer pipes 77.6dB 3.7dB

[0073] When the fan frequency on the top of the machine is 32HZ and the initial noise is 81.7dB, the results are as shown in the following table.

[0074] Number of silencer pipes Noise after noise reduction Reduced noise 3 silencer pipes 77.6dB 4.1dB 4 silencer pipes 77.8dB 3.9dB

[0075] When the fan frequency on the top of the machine is 34HZ and the initial noise is 82.2dB, the results are as shown in the following table.

[0076] Number of silencer pipes Noise after noise reduction Reduced noise 3 silencer pipes 77.9dB 4.3dB 4 silencer pipes 78.3dB 3.9dB

[0077] When the fan frequency on the top of the machine is 36HZ and the initial noise is 81.7dB, the results are as shown in the following table.

[0078] Number of silencer pipes Noise after noise reduction Reduced noise 3 silencer pipes 78.6dB 3.1dB 4 silencer pipes 78.8dB 2.9dB

[0079] When the fan frequency on the top of the machine is 40HZ and the initial noise is 82.7dB, the results are as shown in the following table.

[0080] Number of silencer pipes Noise after noise reduction Reduced noise 3 silencer pipes 80.3dB 2.4dB 4 silencer pipes 80.4dB 2.3dB

[0081] It can be seen that the noise reduction effect is better when the number of the silencer pipes 2 is three.

[0082] It should be noted that the test for detecting the number of silencer pipes 2 and the test for detecting the ratio of the area of ​​the windward area 11 to the ventilation area 20 are conducted on compressors of different displacements and models, and the purpose is to obtain more intuitive data.
