Description

TECHNICAL FIELD

[0001] The present application relates to the compressor technical field, specifically, it is a kind of liquid separator, compressor and refrigeration equipment. BACKGROUND

[0002] In order to prevent liquid strike phenomenon, the suction orifice of the fully enclosed rolling rotor refrigeration compressor is generally equipped with a liquid separator to separate gas and liquid.The traditional liquid separator structure is shown in Figure 1 And 2 It is mainly composed of filter screen assembly 101, inlet pipe 102, elbow pipe 103, partition plate 104 and cylinder 105.

[0003] In addition to the role of gas-liquid separation, the liquid separator also has another important role, which is gas pressure pulsation buffer and sound attenuation effect.Using it can reduce the gas pressure pulsation in the suction process and reduce the suction noise, and improve the stability of the suction process and improve the efficiency of the compressor.

[0004] The structure and function of the liquid separator are equivalent to the internal pipe expansion chamber type silencer, which has the effect of silencer.But due to the influence of working conditions of compressor suction, and with periodicity and intermittence, the internal parts of the liquid separator are complex, and the gas flow in the liquid separator may also appear severe vortex and turbulence.Wrong design may cause noise increase in some frequency bands, and hydraulic compression and other problems.Because the surface area ratio of the liquid separator is large, and the wall thickness of the liquid separator shell is thinner than the wall thickness of the compressor body shell, under the same gas pressure pulsation, it is easier to radiate noise, so the influence of gas dynamic noise is also large. SUMMARY

[0005] The first object of the present application is to provide a liquid separator, which can reduce the vibration of the straight pipe and the support ring to the cylinder of the liquid separator, reduce the vibration of the compressor body shell to the liquid separator, freely adjust the height of the support ring, and further adjust the acoustic cavity mode of the liquid separator, while reducing the external radiation noise of the internal airflow of the liquid separator, effectively reducing the compressor noise.

[0006] The second object of the present application is to provide a compressor with the above-mentioned liquid separator.

[0007] The third object of the present application is to provide a refrigeration equipment with the above-mentioned compressor.

[0008] To achieve the aforementioned first objective, the present invention provides a liquid dispenser, comprising: an outer cylinder having a receiving cavity; a straight tube located within the receiving cavity and extending axially along the outer cylinder; a support ring supporting the straight tube radially; an inner cylinder located within the receiving cavity, with openings at both ends, the support ring fixed within the inner cylinder, the straight tube extending into the inner cylinder and passing through the support ring, and a buffer cavity formed between the inner peripheral wall of the outer cylinder and the outer peripheral wall of the inner cylinder; and a buffer assembly flexibly connecting the inner cylinder and the outer cylinder via the buffer assembly.

[0009] As can be seen from the above solution, by setting an inner cylinder and a buffer assembly, and fixing the support ring for supporting the straight pipe to the inner cylinder, and flexibly connecting the outer cylinder and the inner cylinder through the buffer assembly, the vibration of the support ring on the outer cylinder of the distributor is significantly reduced. The installation position of the support ring does not need to avoid the position of the bracket outside the distributor, and the height of the support ring can be freely adjusted, thereby adjusting the acoustic mode of the distributor's cavity. At the same time, it increases the rigidity of the distributor, making it less likely for the straight pipe mode to be excited, thus reducing the vibration amplitude of the distributor. It also reduces the vibration transmitted from the straight pipe and the support ring to the outer cylinder of the distributor, reduces the vibration transmitted from the compressor housing to the distributor, and reduces the noise radiated from the internal airflow of the distributor, effectively reducing compressor noise. Furthermore, this distributor requires minimal structural changes to existing distributors.

[0010] A preferred embodiment is that the buffer assembly includes an upper buffer and a lower buffer; the upper buffer is clamped between the outer cylinder and the inner cylinder and is positioned near the top of the buffer cavity; the bottom end of the inner cylinder is supported on the outer cylinder by the lower buffer.

[0011] Therefore, by setting buffers at both the top and bottom of the inner cylinder, the flexible connection between the inner and outer cylinders is effectively ensured, while also ensuring the stability of the connection between the two.

[0012] A further design is that the lower buffer is annular and has a first support groove. The first support groove is recessed downward from the top wall of the lower buffer and supports the lower end of the inner cylinder.

[0013] It can be seen that the lower buffer component has a first support groove for engaging with the lower end of the inner cylinder, thereby ensuring the stability of the connection between the inner cylinder and the outer cylinder.

[0014] A further design is to provide a bottom cover at the bottom of the outer cylinder, with the outer periphery of the bottom cover fitting against the inner wall of the outer cylinder; the lower buffer component is provided with a second support groove, which is recessed upward from the bottom wall of the lower buffer component, and the outer periphery of the bottom cover and the second support groove are matched in the axial upper limit of the lower buffer component.

[0015] It can be seen that the positioning of the lower buffer component relative to the outer cylinder is achieved by the cooperation between the second support groove and the outer periphery of the bottom cover.

[0016] A preferred embodiment is that there are two or more upper buffer components, and each upper buffer component is arranged along the circumference of the outer cylinder.

[0017] It can be seen that by setting multiple upper buffer components, the stability of the outer cylinder's support for the inner cylinder in the circumferential direction is ensured.

[0018] A preferred embodiment is that both the upper and lower buffer components are made of elastic material.

[0019] Therefore, the buffer made of elastic material can, on the one hand, avoid the gas force on the support ring from acting directly on the outer cylinder, and on the other hand, reduce the vibration of the compressor body transmitted to the straight pipe of the distributor through the pressure plate.

[0020] A preferred embodiment is that a reflux hole is provided on the peripheral wall of the inner cylinder near the bottom, and the buffer chamber is connected to the inner cavity of the inner cylinder through the reflux hole.

[0021] It can be seen that the reflux hole at the bottom of the inner cylinder allows the liquid and gas in the buffer chamber to flow back to the inner cavity side of the inner cylinder.

[0022] A preferred embodiment is that the inner cylinder is made of metal; and / or the inner cylinder is made of a perforated plate.

[0023] Therefore, it can be seen that the inner cylinder made of metal can play a role in sound insulation, and the perforated plate can play a role in sound absorption.

[0024] A further option is to make the inner cylinder from a micro-perforated plate or a honeycomb plate.

[0025] It is evident that perforated plates, micro-perforated plates, and honeycomb plates have high sound absorption coefficients, low pressure loss, and low airflow regeneration noise. Furthermore, the cavity size can be adjusted according to the actual noise situation, and the required absorption frequency band can be adjusted. Small-hole or micro-perforated plate silencers can better eliminate aerodynamic noise.

[0026] A preferred solution is to arrange the inner and outer cylinders on the same axis.

[0027] Therefore, it can be seen that the inner and outer cylinders are arranged on the same axis, which can ensure that the inner and outer cylinders do not come into contact at any point.

[0028] A preferred embodiment is that the top of the outer cylinder is provided with a top cover and a filter assembly, the filter assembly covers the top opening of the outer cylinder and is located near the connection between the top cover and the outer cylinder, and the top cover is also provided with an air suction pipe, which is connected to the receiving cavity.

[0029] Therefore, it can be seen that the filter assembly separates gas and liquid by filtering impurities and absorbing the impact force of the refrigerant.

[0030] A preferred arrangement is to position the top of the straight pipe close to the top of the inner cylinder.

[0031] Therefore, it can be seen that the straight pipe inside the distributor plays a role in preventing liquid from flowing into the pump body.

[0032] In a preferred embodiment, the dispenser further includes a pressure plate and an elastic element, with the pressure plate sleeved on the outer cylinder and the elastic element separating the pressure plate from the outer cylinder; a support ring is positioned close to the pressure plate along the axial direction of the outer cylinder.

[0033] Therefore, the flexible connection between the inner and outer cylinders can reduce the transmission of compressor vibration to the distributor. This means that the installation position of the support ring does not need to avoid the position of the bracket outside the distributor, and the height of the support ring can be freely adjusted, thereby adjusting the acoustic mode of the distributor.

[0034] To achieve the second objective mentioned above, the present invention provides a compressor, including a compressor body and the aforementioned liquid distributor, wherein the compressor body and the liquid distributor are connected by a straight pipe.

[0035] To achieve the third objective mentioned above, the present invention provides a refrigeration device, including the compressor described above. Attached Figure Description

[0049] See Figure 3 In this embodiment, the refrigeration equipment can be an air conditioner or a refrigerator, and the refrigeration equipment includes a compressor 10.

[0050] The compressor 10 includes a compressor body 1 and a distributor 2 connected to each other. The compressor body 1 includes a casing 11 and a pump body 12 and a motor 13 located inside the casing 11. In the refrigeration equipment, the low-pressure refrigerant enters the pump body 12 through the distributor 2. After being compressed into high-pressure gas in the pump body 12, the low-pressure refrigerant passes through the air gap of the motor 13 and is discharged from the top of the casing 11.

[0051] See Figures 3 to 7 The distributor 2 includes an outer cylinder 31, a top cover 32, a bottom cover 33, a filter assembly 4, a straight pipe 51, a bent pipe 52, a support ring 6, an inner cylinder 7, a buffer assembly 8, a pressure plate 91, and an elastic element 92. The pressure plate 91 is sleeved on the outer cylinder 31, and the elastic element 92 separates the pressure plate 91 from the outer cylinder 31. The casing 11 of the compressor body 1 is fixedly connected to the distributor 2 through the pressure plate 91 to increase the rigidity of the distributor 2 and the system. At the same time, the elastic element 92 surrounds the outer cylinder 31 of the distributor 2 to reduce vibration between the pressure plate 91 and the distributor 2, and between the distributor 2 and the casing 11 of the compressor body 1. Preferably, the elastic element 92 is a rubber pad.

[0052] The outer cylinder 31 is cylindrical and has an internal cavity 311. The inner cylinder 7 is located inside the cavity 311 and is coaxial with the outer cylinder 31. Both the outer cylinder 31 and the inner cylinder 7 extend vertically and have openings at both ends. The top cover 32 and the bottom cover 33 are respectively located at the two ends of the outer cylinder 31 along its axial direction. The inner circumferential wall of the outer cylinder 31 and the outer circumferential wall of the inner cylinder 7 form a buffer cavity 312. The inner cylinder 7 and the outer cylinder 31 are flexibly connected by a buffer assembly 8.

[0053] A straight pipe 51 is located within the receiving cavity 311 and extends axially along the outer cylinder 31. A support ring 6 supports the straight pipe 51 radially. The support ring 6 is fixed in the inner cylinder 7 and is positioned axially along the outer cylinder 31, close to the pressure plate 91. The straight pipe 51 extends into the inner cylinder 7 and passes through the support ring 6. The lower end of the straight pipe 51 is connected to the compressor body 1 via a bend 52. The distributor 2 is connected to the compressor body 1 via a pipeline structure consisting of the straight pipe 51 and the bend 52. The top end of the straight pipe 51 is positioned close to the top end of the inner cylinder 7. Inside the distributor 2, the straight pipe 51 serves to prevent liquid from flowing into the pump body 12 of the compressor body 1. The pipeline structure consisting of the straight pipe 51 and the bend 52 is the outlet pipe of the distributor 2. The bend 52 is fixed to the casing 11 of the compressor body 1 by welding.

[0054] The support ring 6 includes a bottom wall 61 and a peripheral wall 62. A through hole 63 is formed in the bottom wall 61, and the straight pipe 51 is clearance-fitted into the through hole 63. The peripheral wall 62 extends axially upward from the outer periphery of the bottom wall 61 along the outer cylinder 31 and is welded to the inner cylinder 7. An oil passage hole 64 is provided axially through the bottom wall 61.

[0055] The top of the outer cylinder 31 is provided with a top cover 32 and a filter assembly 4. The filter assembly 4 covers the top opening of the outer cylinder 31 and is located near the connection between the top cover 32 and the outer cylinder 31. The top cover 32 is also provided with a suction pipe 34, which is connected to the receiving cavity 311. The filter assembly 4 performs gas-liquid separation by filtering impurities and absorbing the impact force of the refrigerant.

[0056] The inner cylinder 7 is made of metal, for example, steel plate. Four return holes 71 are provided near the bottom of the inner cylinder 7's circumferential wall. These four return holes 71 are evenly arranged along the circumference of the inner cylinder 7. The buffer cavity 312 communicates with the inner cavity of the inner cylinder 7 through the return holes 71. The return holes 71 at the bottom of the inner cylinder 7 allow liquid and gas in the buffer cavity 312 to flow back to the inner cavity side of the inner cylinder 7. In other embodiments, the inner cylinder 7 can also be made of a perforated plate, or a micro-perforated plate or honeycomb plate. Perforated plates, micro-perforated plates, and honeycomb plates have high sound absorption coefficients, low pressure loss, low airflow regeneration noise, and the cavity size can be adjusted according to the actual noise situation to adjust the required absorption frequency band. Small-hole or micro-perforated plate silencers can better eliminate aerodynamic noise.

[0057] The buffer assembly 8 includes an upper buffer 81 and a lower buffer 82. Both the upper buffer 81 and the lower buffer 82 are made of elastic material. The upper buffer 81 is clamped between the outer cylinder 31 and the inner cylinder 7 and is located near the top of the buffer cavity 312. There are two or more upper buffers 81. Each upper buffer 81 is arranged along the circumference of the outer cylinder 31. By setting multiple upper buffers 81, the stability of the outer cylinder 31 in supporting the inner cylinder 7 in the circumference is ensured.

[0058] The lower buffer member 82 is a circular rubber gasket. The lower buffer member 82 has a first support groove 821 and a second support groove 822. The first support groove 821 is recessed downward from the top wall of the lower buffer member 82 and supports the lower end of the inner cylinder 7. By opening the first support groove 821 on the lower buffer member 82 to cooperate with the lower end of the inner cylinder 7, the bottom end of the inner cylinder 7 is supported on the outer cylinder 31 by the lower buffer member 82, thereby ensuring the stability of the connection between the inner cylinder 7 and the outer cylinder 31.

[0059] The outer periphery of the bottom cover 33 fits against the inner wall of the outer cylinder 31. The second support groove 822 is recessed upward from the bottom wall of the lower buffer member 82. The outer periphery of the bottom cover 33 and the second support groove 822 are engaged in the axial upper limit of the lower buffer member 82. The positioning of the lower buffer member 82 relative to the outer cylinder 31 is achieved through the engagement of the second support groove 822 and the outer periphery of the bottom cover 33.

[0060] Because the airflow pressure pulsation amplitude of the straight pipe 51 is much greater than the gas pressure pulsation amplitude of the inner wall of the distributor 2, the suction pipe 34 vibrates under the action of airflow pressure pulsation, which will cause the outer cylinder 31 of the distributor 2 to vibrate and radiate noise. Reducing the vibration of the straight pipe 51 can effectively reduce the noise of the distributor 2. When the refrigerant enters the interior of the distributor 2 through the suction pipe 34, the refrigerant directly impacts the filter assembly 4. The liquid refrigerant and the refrigeration oil contained in the refrigerant are thrown onto the walls of the outer cylinder 31 and the inner cylinder 7. During this process, the liquid refrigerant will quickly vaporize into gaseous refrigerant. Some of it continues to enter the inner cavity of the distributor 2 through the oil return hole at the bottom of the inner cylinder 7, or the remaining liquid refrigerant and refrigeration oil flow down the wall through the support ring 6 to the bottom of the outer cylinder 31 of the distributor 2. Most of the liquid enters the wall between the outer cylinder 31 and the inner cylinder 7 and vaporizes, making the airflow in the inner ring of the inner cylinder 7 more stable. The gaseous refrigerant distributed at the top of the outer cylinder 31 enters the straight pipe 51 due to pressure. The deflection f at the end face of the straight pipe 51... X The calculation formula is:

[0061] f X = (F*l^3) / (3*E*I);

[0062] Where F is the force acting on the end face of the straight pipe 51, l is the distance from the end face of the straight pipe 51 to the end face of the support ring 6, E is the elastic modulus of the material, and I is the moment of inertia of the cross-section of the straight pipe 51.

[0063] When the support ring 6 is located in the upper middle part of the inner cylinder 7, the distance l from the straight pipe 51 to the end face of the support ring 6 is small, and the deflection f of the end face of the straight pipe 51 is small. X The vibration is reduced, and due to the action of the upper buffer 81, the straight pipe 51 is less affected by the casing 11 of the compressor body 1, thus resulting in less vibration. When the support ring 6 is located in the lower middle part of the inner cylinder 7, the straight pipe 51 vibrates due to the suction pulsation, and the sound waves are reflected back through the inner cylinder 7, thereby reducing the outward radiation of noise. The end face of the support ring 6 is the upper surface of the bottom wall 61 of the support ring.

[0064] As can be seen from the above, by setting an inner cylinder and a buffer assembly, and fixing the support ring for supporting the straight pipe to the inner cylinder, and flexibly connecting the outer cylinder and the inner cylinder through the buffer assembly, the gas force on the support ring can be avoided from directly acting on the outer cylinder, while reducing the vibration of the straight pipe of the distributor transmitted from the compressor body through the pressure plate. The vibration of the support ring on the outer cylinder of the distributor is significantly reduced. The installation position of the support ring does not need to avoid the position of the bracket outside the distributor, and the height of the support ring can be freely adjusted, thereby adjusting the acoustic mode of the distributor and increasing the rigidity of the distributor, making it less likely for the straight pipe mode to be excited, and reducing the vibration amplitude of the distributor. At the same time, it can reduce the vibration transmitted from the straight pipe and the support ring to the outer cylinder of the distributor, reduce the vibration transmitted from the compressor body shell to the distributor, and reduce the noise radiated by the airflow inside the distributor, effectively reducing the compressor noise.

[0065] Furthermore, the upper buffer can also be made of sound-absorbing material. The material, quantity, shape, and arrangement of the upper buffer can all be changed as needed. For example, the number of upper buffers can be one or more. The shape, quantity, and size of the return holes can also be changed as needed. The above changes can also achieve the purpose of this invention.

[0066] Finally, it should be emphasized that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
