Silencer oil separator and compressor

Abstract

This invention provides a noise-reducing oil separator and a compressor. The noise-reducing oil separator includes a cylindrical body and an end cap connected to each other. The cylindrical body has a noise-reducing chamber for eliminating noise generated by the fluid entering it. A first separation chamber and a second separation chamber are located between the cylindrical body and the end cap. The outlet of the noise-reducing chamber is connected to the inlet of the first separation chamber, and the outlet of the first separation chamber is connected to the inlet of the second separation chamber. The fluid flows along the side wall of the first separation chamber, where centrifugal force separates the oil. A portion of the oil is adsorbed onto the side wall of the first separation chamber. The fluid output from the first separation chamber enters the second separation chamber, where it flows along the side wall. Centrifugal force further separates the oil, which is adsorbed onto the side wall of the second separation chamber due to liquid surface tension. After two stages of oil-gas separation in the first and second separation chambers, the fluid discharged from the second separation chamber contains less oil, resulting in good noise reduction and oil-gas separation effects.

Description

Technical Field

[0001] This invention relates to the field of compressor technology, and more specifically, to a silencer oil separator and a compressor. Background Technology

[0002] The exhaust cavity of a horizontal compressor occupies a relatively small space. The refrigerant and refrigeration oil carried in the exhaust cannot be effectively retained, separated, and deposited in the exhaust cavity before being carried away from the compressor. Even with a cyclone oil-gas separator installed at the exhaust outlet, which can effectively separate some lubricating oil, as the operating frequency increases, at high speeds and high flow rates, a larger proportion of the lubricating oil separated by the oil-gas separator is carried away from the compressor by high-speed agitation compared to the proportion separated by the oil separator, thus affecting the effectiveness of the oil-gas separator in separating lubricating oil. The narrow exhaust outlet cavity of the stationary scroll also causes significant exhaust pulsation, generating exhaust noise and affecting the compressor's sound quality and perceived quality.

[0003] Therefore, a device is needed for compressors that can effectively improve oil discharge and reduce noise. Summary of the Invention

[0063] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0064] like Figures 1 to 8 As shown, an embodiment of the present invention provides a noise-reducing oil separator, including a cylindrical body 10 and an end cap 20 connected to each other. The cylindrical body 10 has a noise-reducing cavity 30, which is used to eliminate noise generated by the fluid entering it. A first separation cavity 40 and a second separation cavity 50 are provided between the cylindrical body 10 and the end cap 20. The outlet of the noise-reducing cavity 30 is connected to the inlet of the first separation cavity 40, and the outlet of the first separation cavity 40 is connected to the inlet of the second separation cavity 50. The first separation cavity 40 and the second separation cavity 50 respectively guide the fluid located inside them to flow along the inner wall so as to separate the gas and liquid in the fluid.

[0065] This solution eliminates noise generated by the fluid entering the silencing chamber 30, preventing noise from affecting the user experience. The outlet of the silencing chamber 30 is connected to the inlet of the first separation chamber 40. The fluid in the silencing chamber 30 enters the first separation chamber 40 and flows along its sidewall. Centrifugal force separates the oil from the fluid, and some oil adheres to the sidewall of the first separation chamber 40 due to surface tension. The fluid output from the first separation chamber 40 enters the second separation chamber 50, where it flows along its sidewall. Centrifugal force further separates the oil from the fluid, and the oil adheres to the sidewall of the second separation chamber 50 due to surface tension. After two stages of oil-gas separation in the first and second separation chambers 40, the fluid discharged from the second separation chamber 50 contains less oil. The oil adsorbed on the sidewalls of the first and second separation chambers 40 accumulates under gravity and is then discharged, preventing the separated oil from being carried away by the fluid and improving the oil-gas separation effect.

[0066] like Figure 3 As shown, the silencing cavity 30 has an umbrella-shaped cross section perpendicular to the axial direction. The silencing cavity 30 includes an umbrella head cavity 31 and an umbrella handle cavity 32 that are interconnected. A part of the edge of the umbrella head cross section of the umbrella head cavity 31 is an arc, and the umbrella handle cross section of the umbrella handle cavity 32 is rectangular. The umbrella head cross section and the umbrella handle cross section are connected by an arc.

[0067] With this design, a portion of the umbrella head cross-section of the umbrella head cavity 31 has an arc shape, making the fluid entry into the umbrella head cavity 31 smoother and less prone to noise generation. The umbrella head cross-section consists of an arc and a chord line forming a sound-absorbing resonating part, with the arc angle less than 180° and the arc and chord line smoothly connecting to form an angle region of less than 90°. The umbrella handle cross-section is rectangular, and the umbrella head cross-section and the umbrella handle cross-section are smoothly connected. When the fluid enters the sound-absorbing cavity 30, it first enters the umbrella handle cavity 32, and then enters the resonating area of ​​the umbrella head cavity 31. The refraction at the curved surface of the resonating part cancels out the noise, and some of the noise is absorbed, achieving the effect of sound absorption and noise reduction.

[0068] like Figure 7As shown, the inlet and outlet of the silencing cavity 30 are located at the two ends of the axial direction of the silencing cavity 30, and the volume of the umbrella head cavity 31 is greater than the volume of the umbrella handle cavity 32.

[0069] With this configuration, when the fluid enters the silencing cavity 30, it first enters the umbrella handle cavity 32, and then the resonance area of ​​the umbrella head cavity 31. The fluid is refracted by the curved surface at the resonance point, causing mutual cancellation and absorption of some noise, thus achieving the effect of noise reduction and silencing. The axial depth of the umbrella head cavity 31 is greater than the axial depth of the umbrella handle cavity 32. The volume of the silencing cavity is determined according to the following formula:

[0070]

[0071] Where c is the speed of sound, s and L are the cross-sectional area and depth of the static disk exhaust hole, respectively, V is the volume of the silencing cavity 6a, and f is the noise reduction frequency. By varying the axial depth, the volume of the umbrella head cavity 31 is made larger than the volume of the umbrella handle cavity 32.

[0072] like Figure 4 As shown, the first separation chamber 40 has a first arc-shaped inner wall 41, which guides the flow of fluid within the first separation chamber 40. The second separation chamber 50 has a second arc-shaped inner wall 51, which guides the flow of fluid within the second separation chamber 50.

[0073] With this configuration, the first arc-shaped inner wall 41 guides the fluid to flow within the first separation chamber 40. Centrifugal force separates the oil droplets from the fluid, and the surface tension of the liquid causes the oil droplets to adhere to the inner wall of the first separation chamber 40, preventing them from leaving the first separation chamber 40 with the fluid. The fluid that has been de-oiled in the first separation chamber 40 enters the second separation chamber 50, where the second arc-shaped inner wall 51 guides the fluid to flow. Centrifugal force separates the oil droplets from the fluid, and the surface tension of the liquid causes the oil droplets to adhere to the inner wall of the second separation chamber 50, preventing them from leaving the second separation chamber 50 with the fluid.

[0074] like Figure 4 As shown, the first separation chamber 40 has a stop wall 42, the inlet of the first separation chamber 40 faces the stop wall 42, the stop wall 42 and the first arc-shaped inner wall 41 have an included angle, and the silencing chamber 30 is located between the first arc-shaped inner wall 41 and the second arc-shaped inner wall 51; wherein, the stop wall 42, the first arc-shaped inner wall 41 and the second arc-shaped inner wall 51 guide the fluid to change direction in sequence.

[0075] With this configuration, the baffle wall 42 and the first arc-shaped inner wall 41 form an angle. Fluid entering from the inlet of the first separation chamber 40 impacts the baffle wall 42 and is guided by it to the first arc-shaped inner wall 41. Fluid flowing out of the first separation chamber 40 enters the second separation chamber 50. Guided by the baffle wall 42, the first arc-shaped inner wall 41, and the second arc-shaped inner wall 51, the fluid is ejected by centrifugal force, causing oil droplets to adhere to the inner wall and not leave with the fluid. The bottom of the muffler oil separator has an oil drain port. When the oil in the muffler oil separator accumulates to a certain amount, it leaves the muffler oil separator from the drain port under gravity.

[0076] like Figures 1 to 5 As shown, the cylinder 10 has a connecting channel 11, and the silencing cavity 30 is connected to the first separation cavity 40 through the connecting channel 11; the cylinder 10 has a flow guiding channel 12, or the end cap 20 has a flow guiding channel 12, or the cylinder 10 and the end cap 20 have a flow guiding channel 12, and the first separation cavity 40 is connected to the second separation cavity 50 through the flow guiding channel 12, and the side wall of the second separation cavity 50 has a discharge port 52.

[0077] With this configuration, the connecting channel 11 transports the fluid in the silencing chamber 30 to the first separation chamber 40, and the guiding channel 12 transports the fluid in the first separation chamber 40 to the second separation chamber 50. The fluid in the second separation chamber 50 is discharged through the outlet 52 after being separated by centrifugal force.

[0078] like Figure 6 As shown, the cylinder 10 includes a silencer cylinder 13 and a receiving cylinder 14 connected to each other. The silencer cylinder 13 has a silencer cavity 30. The silencer cylinder 13, the receiving cylinder 14 and the end cap 20 have a first separation cavity 40, a second separation cavity 50 and a flow guide channel 12. The first separation cavity 40 is connected to the second separation cavity 50 through the flow guide channel 12. The bottom wall of the silencer cylinder 13 has a connecting channel 11, which connects the silencer cavity 30 and the first separation cavity 40.

[0079] In this configuration, the first separation chamber 40, the second separation chamber 50, and the flow guiding channel 12 are located between the silencer 13, the receiving cylinder 14, and the end cap 20. The flow guiding channel 12 connects the first separation chamber 40 and the second separation chamber 50. The connecting channel 11 transports the fluid in the silencer 30 to the first separation chamber 40.

[0080] like Figure 4As shown, the end cap 20 includes a cap body 21 and a fixing ring 22 and a fixing block 23 disposed on the cap body 21. The outer wall of the fixing ring 22 cooperates with the inner wall of the receiving cylinder 14. The fixing block 23 is disposed on the inner side of the fixing ring 22. The fixing block 23 abuts against the muffler 13. A second separation cavity 50 is formed between the end face of the fixing block 23, the outer wall of the muffler 13 and the inner wall of the receiving cylinder 14. The outer wall of the cylinder 10 has an annular sealing groove 15, which is used to install the sealing element 93.

[0081] With this configuration, the outer wall of the fixing ring 22 mates with the inner wall of the receiving cylinder 14, fixing the end cap 20 to the cylinder 10 together. The fixing block 23 is located inside the fixing ring 22, abutting against the muffler 13, with its end face serving as the top wall of the second separation chamber 50. The second separation chamber 50 is formed between the end face of the fixing block 23, the outer wall of the muffler 13, and the inner wall of the receiving cylinder 14, preventing the top of the second separation chamber 50 from communicating with the first separation chamber 40. This ensures that the first and second separation chambers 40 are connected only through the guide channel 12. The annular sealing groove 15 is used to install the sealing element 93, making the installation of the muffler oil separator more secure and preventing leakage.

[0082] like Figures 9 to 14 As shown, Embodiment 2 of the present invention provides a silencer oil separator. The cylinder 10 includes a chassis 16, a silencer cylinder 13, and a separator block 17 connected in sequence. The silencer cavity 30 is disposed in the chassis 16 and the silencer cylinder 13. The silencer cylinder 13 has a connecting channel 11 at the end away from the chassis 16, which connects the silencer cavity 30 to the first separation cavity 40. The separator block 17 is disposed at the end of the silencer cylinder 13 away from the chassis 16, and the connecting channel 11 is located on the side of the separator block 17 facing the first separation cavity 40. The outer wall of the silencer cylinder 13 has a guide channel 12, which connects the first separation cavity 40 and the second separation cavity 50.

[0083] With this configuration, the silencer 13 and the separator 17 are connected together, separating the first separation chamber 40 and the second separation chamber 50, so that the first separation chamber 40 and the second separation chamber 50 are connected only through the guide channel 12. The connecting channel 11 transports the fluid in the silencer 30 to the first separation chamber 40, and the fluid in the first separation chamber 40 enters the second separation chamber 50 through the guide channel 12.

[0084] like Figure 10As shown, the end cap 20 has a cylindrical structure and is fitted onto the outside of the cylinder 10. The outer walls of the chassis 16 and the muffler 13 are fitted with the inner wall of the end cap 20. The partition block 17 abuts against the inner bottom wall of the end cap 20. The partition block 17 and the muffler 13 separate the first separation chamber 40 from the second separation chamber 50 so that the first separation chamber 40 is connected to the connecting channel 11 separately. The guide channel 12 is located between the outer wall of the muffler 13 and the inner wall of the end cap 20. The outer wall of the end cap 20 has an annular sealing groove 15, which is used to install the sealing element 93.

[0085] With this configuration, the end cap 20 is a cylindrical structure, fitted onto the outside of the cylindrical body 10. The outer walls of the base 16 and the muffler 13 mate with the inner wall of the end cap 20. The end cap 20 fitted onto the cylindrical body 10 thus forms the first separation chamber 40, the second separation chamber 50, and the flow channel 12. The partition block 17 abuts against the inner bottom wall of the end cap 20. The base 16 serves as the bottom wall of the first separation chamber 40 and the second separation chamber 50, and the inner bottom wall of the end cap 20 serves as the top wall of the first separation chamber 40 and the second separation chamber 50. The partition block 17 and the muffler 13 separate the first separation chamber 40 and the second separation chamber 50, allowing the first separation chamber 40 to communicate independently with the connecting channel 11, while the first separation chamber 40 and the second separation chamber 50 can only communicate through the flow channel 12.

[0086] like Figure 15 As shown, Embodiment 3 of the present invention provides an exhaust valve. The silencer oil separator also includes an exhaust valve 60, which is disposed on the cylinder 10 or the end cover 20. The exhaust valve 60 is used to discharge fluid that has reached a set pressure and to prevent the discharged fluid from flowing back.

[0087] With this configuration, the exhaust valve 60 is located on the cylinder 10 or the end cap 20. When the fluid reaches the set pressure, it opens the exhaust valve 60 to discharge. The exhaust valve 60 prevents the discharged fluid from flowing back, thus avoiding increased power consumption.

[0088] like Figures 15 to 17 As shown, the exhaust valve 60 includes an exhaust baffle 61 and an exhaust valve plate 62. The side wall or top wall of the second separation chamber 50 is provided with an exhaust port 52. One end of the exhaust valve plate 62 and the exhaust baffle 61 are both connected to the cylinder 10 or the end cap 20. The other end of the exhaust valve plate 62 is a movable end and covers the exhaust port 52. The unfixed end of the exhaust baffle 61 is spaced apart from the exhaust port 52. The exhaust baffle 61 is used to limit the exhaust valve plate 62.

[0089] With this configuration, the exhaust valve 60 is located at the outlet 52 of the second separation chamber 50 to prevent the discharged fluid from flowing back. One end of the exhaust valve plate 62 and the exhaust baffle 61 are both fixed with bolts or rivets, while the other end of the exhaust valve plate 62 is a movable end. When the fluid reaches a set pressure, it opens the exhaust valve plate 62 to discharge. The exhaust baffle 61 limits the movable end of the exhaust valve plate 62, preventing excessive pressure from the discharged fluid and damage to the exhaust valve plate 62.

[0090] like Figure 15 As shown, the exhaust valve 60 includes an exhaust baffle 61 and an exhaust valve plate 62. The cylinder 10 has a connecting channel 11, which connects the first separation chamber 40 and the second separation chamber 50. One end of the exhaust valve plate 62 and the exhaust baffle 61 are both connected to the cylinder 10. The other end of the exhaust valve plate 62 is a movable end and covers the outlet of the connecting channel 11. The unfixed end of the exhaust baffle 61 is spaced apart from the connecting channel 11. The exhaust baffle 61 is used to limit the exhaust valve plate 62.

[0091] With this configuration, the exhaust valve 60 is located at the outlet of the connecting channel 11 to prevent the discharged fluid from flowing back. One end of the exhaust valve plate 62 and the exhaust baffle 61 are both fixed with bolts or rivets. The other end of the exhaust valve plate 62 is a movable end; when the fluid reaches a set pressure, it opens the exhaust valve plate 62 to discharge. The exhaust baffle 61 limits the movable end of the exhaust valve plate 62, preventing excessive pressure from the discharged fluid and damage to the exhaust valve plate 62.

[0092] According to another aspect of the present invention, a compressor is provided, comprising a housing 71, a moving scroll 72, a stationary scroll 73, and the aforementioned muffler oil separator. The moving scroll 72 is rotatably disposed within the housing 71, and the stationary scroll 73 is fixedly disposed within the housing 71. The muffler oil separator is fixedly connected to the stationary scroll 73. A compression chamber 74 is provided between the moving scroll 72 and the stationary scroll 73, and the outlet of the compression chamber 74 is connected to the inlet of the muffler oil separator.

[0093] With this configuration, the outlet of the compression chamber 74 is connected to the outlet of the muffler oil separator. The muffler oil separator silences the fluid discharged from the compression chamber 74 and separates the oil and gas, resulting in a lower oil content in the fluid discharged from the muffler oil separator and less noise generated by the fluid discharged from the compression chamber 74, thus improving the user experience.

[0094] like Figure 20 As shown, the stationary scroll 73 has a pressure relief hole 731, and the compressor also includes a pressure relief component 80. One end of the pressure relief component 80 is fixed to the end face of the stationary scroll 73, and the other end of the pressure relief component 80 is a movable end that covers the pressure relief hole 731. The end face of the silencer oil separator near the stationary scroll 73 has a limiting slope, which limits the movable end of the pressure relief component 80. When the pressure in the compression chamber 74 reaches the set value, the pressure relief component 80 opens the pressure relief hole 731.

[0095] With this configuration, the pressure relief hole 731 is used to discharge fluid from the compression chamber 74 when the pressure in the compression chamber 74 is high, thus relieving pressure. The pressure relief component 80 is used to stop the fluid in the compression chamber 74; pressure relief will only occur when the pressure in the compression chamber 74 reaches a set value. The limiting slope limits the movable end of the pressure relief component 80, preventing damage to the pressure relief component 80 due to excessive fluid pressure. At the same time, the limiting slope allows the movable end of the pressure relief component 80 to open.

[0096] like Figures 18 to 21 As shown, the pressure relief component 80 includes a fixing plate 81 and at least two pressure relief plates 82 disposed on the fixing plate 81. The fixing plate 81 is fixed to the end face of the stationary volute 73. The end of each pressure relief plate 82 facing away from the fixing plate 81 is a movable end and each covers a pressure relief hole 731. When the pressure in the compression chamber 74 reaches a set value, the pressure relief plate 82 opens the corresponding pressure relief hole 731. Alternatively, the pressure relief component 80 includes at least two pressure relief plates 82 disposed at intervals. One end of each pressure relief plate 82 is fixed to the end face of the stationary volute 73, and the other end of each pressure relief plate 82 is a movable end and each covers a pressure relief hole 731. When the pressure in the compression chamber 74 reaches a set value, the pressure relief plate 82 opens the corresponding pressure relief hole 731.

[0097] With this configuration, the fixing plate 81 is fixed to the end face of the stationary vortex disk 73 by fasteners such as bolts or rivets. One end of the pressure relief plate 82 is fixed to the fixing plate 81, and the other end of the pressure relief plate 82 is a movable end. Each pressure relief plate 82 covers a pressure relief hole. The pressure relief plate 82 stops the fluid. When the fluid pressure reaches the set value, the pressure relief plate 82 opens the pressure relief hole 731 to release pressure.

[0098] The pressure relief component 80 includes at least two spaced-apart pressure relief plates 82, one end of which is fixed to the end face of the stationary vortex disk 73 by fasteners such as bolts or rivets. Each pressure relief plate 82 corresponds to a pressure relief hole 731. When the fluid pressure reaches a set value, each pressure relief plate 82 opens the corresponding pressure relief hole 731 to relieve pressure.

[0099] like Figure 21 As shown, the compressor also includes a first elastic element 91. The two ends of the first elastic element 91 abut against the muffler oil distributor and the inner wall of the outer casing 71, respectively. The first elastic element 91 presses the muffler oil distributor onto the stationary scroll 73.

[0100] With this configuration, the first elastic element 91 presses the muffler oil separator firmly against the stationary volute 73, limiting the position of the muffler oil separator. The first elastic element 91 also reduces vibration of the muffler oil separator, preventing damage from vibration.

[0101] like Figure 22As shown, the first elastic element 91 includes a clamping ring 911 and a plurality of support feet 912. The support feet 912 are connected to the clamping ring 911 and are inclined relative to the clamping ring 911. The clamping ring 911 abuts against the muffler oil separator, and the ends of the support feet 912 that are away from the clamping ring 911 abut against the inner wall of the housing 71.

[0102] With this configuration, the clamping ring 911 abuts against the muffler oil separator. When the first elastic element 91 is subjected to the force of the muffler oil separator, the support foot 912 undergoes elastic deformation, thus preventing the muffler oil separator from vibrating and being damaged.

[0103] like Figure 23 As shown, the compressor also includes a second elastic element 92, the two ends of which abut against the stationary scroll 73 and the silencer oil separator, respectively.

[0104] With this configuration, the first elastic element 91 and the second elastic element 92 abut against the two ends of the muffler oil separator, respectively. When the muffler oil separator vibrates, the first elastic element 91 and the second elastic element 92 absorb the force of the vibration and protect the muffler oil separator.

[0105] like Figure 1 As shown, the outer casing 71 includes a housing 711 and a front cover 712 connected to each other. The stationary scroll 73 is fixedly connected to the front cover 712. A high-pressure chamber 75 is provided between the stationary scroll 73 and the front cover 712. A silencer oil separator is partially disposed in the high-pressure chamber 75. The stationary scroll 73 has an annular protrusion 732. A portion of the outer wall of the silencer oil separator mates with the inner wall of the annular protrusion 732. Fluid in the compression chamber 74 enters the high-pressure chamber 75 through the silencer oil separator. The compressor also includes a seal 93, which is installed between the outer wall of the silencer oil separator and the inner wall of the annular protrusion 732.

[0106] With this configuration, the muffler oil separator is installed inside the annular protrusion 732, which limits its movement and allows for better communication between the muffler oil separator and the exhaust port on the stationary vortex plate 73, preventing fluid leakage. The seal 93 is installed between the outer wall of the muffler oil separator and the inner wall of the annular protrusion 732, enhancing the sealing strength and further preventing fluid leakage.
