Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a liquid blocking filter disc for a horizontal liquid accumulator and a horizontal liquid accumulator and a compressor having the same. Background Art

[0002] As an important component of the compressor, the liquid accumulator has the main function of separating the liquid and gaseous refrigerants and storing the liquid refrigerant at its bottom until it is converted into gaseous state, so as to prevent the liquid refrigerant from entering the compressor pump body and causing the adverse phenomenon of liquid refrigerant knocking on the cylinder, leading to abnormal working conditions such as damage to the compressor pump body.

[0003] Based on the installation direction, liquid receivers can be divided into two types: vertical and horizontal. Horizontal receivers are installed horizontally, with their axis usually flush with the horizontal plane. Due to the horizontal arrangement of horizontal receivers, the liquid refrigerant contained in the low-temperature, low-pressure refrigerant sucked into the compressor has little sedimentation space and a short sedimentation distance in the receiver, which can cause liquid backflow, leading to adverse phenomena such as liquid hammer and over-compression. To address the liquid backflow problem, a common method is to add a simple baffle inside the receiver housing, but this reduces the refrigerant flow rate in the receiver, affecting the receiver's suction and exhaust efficiency, resulting in reduced compression efficiency. Utility Model Content

[0004] Based on this, the purpose of the present invention is to overcome the shortcomings of the existing technology and provide a horizontal liquid reservoir and compressor. The liquid-blocking filter plate for the horizontal liquid reservoir and the horizontal liquid reservoir and compressor having the same according to the embodiment of the present invention can effectively reduce the liquid backflow phenomenon and improve the performance of the compressor while ensuring the suction and exhaust efficiency.

[0005] In order to achieve the above-mentioned purpose, the first aspect of the embodiment of the present invention provides a liquid-blocking filter disc for a horizontal liquid reservoir, the liquid-blocking filter disc is disc-shaped, and the outer circumference of the liquid-blocking filter disc is provided with a flange portion, and the flange portion is used to be connected and fixed to the inner circumferential wall of the horizontal liquid reservoir; the two end faces of the liquid-blocking filter disc in the axial direction are respectively a liquid-blocking surface and a leeward surface, and the middle part of the liquid-blocking surface protrudes in the axial direction away from the leeward surface to form a spherical liquid-blocking diversion portion, and a first through hole is opened through the middle of the liquid-blocking diversion portion, and the liquid-blocking diversion portion is provided with a first blocking ear on one side of the leeward surface, the first blocking ear is connected to the edge of the first through hole, and the first blocking ear and the first through hole form a first diversion port with an inclined upward diversion direction; a plurality of second through holes are opened through the upper half area of ​​the liquid-blocking filter disc, and the area of ​​each second through hole is smaller than the area of ​​the first through hole.

In this way, when the high-speed airflow carrying the liquid-phase refrigerant hits the liquid blocking surface of the liquid blocking filter disc head-on, the high-speed gas is first diverted and guided by the liquid blocking diverter to avoid the high-speed airflow passing through the first through hole. At the same time, the ingenious design of the first blocking ear on the first through hole is used to change the direction of the high-speed gas passing through the first through hole to an inclined direction. Upward, in this way, the high-speed gas after passing through the first through hole will collide with the top of the inner wall of the horizontal liquid reservoir, thereby increasing the impact surface of the liquid-phase refrigerant and making the sedimentation effect of the liquid-phase refrigerant better; in addition, in order to ensure the suction and exhaust efficiency of the horizontal liquid reservoir, a number of second through holes are also provided in the upper half of the liquid-blocking filter disc, and the area of ​​the second through holes is made smaller than the area of ​​the first through holes. In this way, the first through hole and the first blocking ear are used as the main exhaust channels, and the second through holes are used as auxiliary exhaust channels, which can further improve the suction and exhaust efficiency of the horizontal liquid reservoir.

[0032] To further illustrate various embodiments, this utility model is provided with accompanying drawings. These drawings form part of the disclosure of this utility model and are primarily used to illustrate the embodiments and, in conjunction with the relevant description in the specification, to explain the operating principles of the embodiments. By referring to these drawings, those skilled in the art will be able to understand other possible implementations and the advantages of this utility model.

[0033] In related technologies, the axis of a horizontal accumulator is typically aligned with the horizontal plane, resulting in a small amount of space and distance for the liquid refrigerant to settle within the accumulator. This can lead to problems such as liquid backflow, liquid hammer, and over-compression. To address this, a common approach is to add a simple baffle inside the accumulator housing. However, this reduces the refrigerant flow rate within the accumulator, affecting the accumulator's suction and exhaust efficiency and resulting in reduced compression efficiency.

[0034] In view of this, an embodiment of the present invention provides a liquid-blocking filter plate for a horizontal liquid reservoir and a horizontal liquid reservoir and a compressor having the same. According to the liquid-blocking filter plate for a horizontal liquid reservoir and a horizontal liquid reservoir and a compressor having the same, while ensuring the suction and exhaust efficiency, the liquid return phenomenon can be effectively reduced, the compressor performance can be improved, the flow pulsation can be improved and the noise can be reduced.

[0035] See also Figures 1 to 3 The first aspect of the embodiment of the present invention provides a liquid blocking filter disc 10 for a horizontal liquid reservoir 30. The liquid blocking filter disc 10 is disc-shaped, and a flange portion 13 is provided on the outer circumference of the liquid blocking filter disc 10. The flange portion 13 is used to be connected and fixed to the inner circumferential wall of the horizontal liquid reservoir 30. The two end faces of the liquid blocking filter disc 10 in the axial direction are respectively a liquid blocking surface 11 and a leeward surface 12. The middle part of the liquid blocking surface 11 protrudes in the axial direction away from the leeward surface 12 to form a spherical liquid blocking diversion portion 14. A first through hole 15 is provided through the middle of the liquid blocking diversion portion 14, and a first blocking ear 20 is provided on the side of the leeward side 12 of the liquid blocking diversion portion 14. The first blocking ear 20 is connected to the edge of the first through hole 15, and the first blocking ear 20 and the first through hole 15 form a first diversion port with an inclined upward diversion direction; a plurality of second through holes 16 are provided through the upper half area of ​​the liquid blocking filter disc 10, and the area of ​​each second through hole 16 is smaller than the area of ​​the first through hole 15.

[0036] Therefore, according to the embodiment of the present invention, the horizontal liquid storage device 30 uses a liquid blocking filter disc 10, by providing a spherical liquid blocking diverter 14 on the liquid blocking surface 11 of the liquid blocking filter disc 10, and a first through hole 15 is opened in the middle of the liquid blocking diverter 14. In this way, when the high-speed airflow carrying the liquid phase refrigerant hits the liquid blocking surface 11 of the liquid blocking filter disc 10 head-on, the high-speed gas is first diverted and guided by the liquid blocking diverter 14 to avoid the high-speed airflow from passing through the first through hole 15 entirely. At the same time, the ingenious design of the first blocking ear 20 on the first through hole 15 is utilized to change the direction of the high-speed gas passing through the first through hole 15. The first through hole 15 is tilted upward, so that the high-speed gas after passing through the first through hole 15 will collide with the top of the inner wall of the horizontal liquid reservoir 30, thereby increasing the impact surface of the liquid-phase refrigerant and making the sedimentation effect of the liquid-phase refrigerant better. In addition, in order to ensure the suction and exhaust efficiency of the horizontal liquid reservoir 30, a plurality of second through holes 16 are also provided in the upper half of the liquid-blocking filter disc 10, and the area of ​​the second through holes 16 is smaller than the area of ​​the first through holes 15. In this way, the first through holes 15 and the first blocking ears 20 are used as the main exhaust channels, and the second through holes 16 are used as auxiliary exhaust channels, which can further improve the suction and exhaust efficiency of the horizontal liquid reservoir 30. In other words, the liquid-blocking filter disc 10 used for the horizontal liquid reservoir 30 according to the embodiment of the utility model can effectively reduce the liquid backflow phenomenon, improve the performance of the compressor, improve the flow pulsation and reduce the noise on the basis of ensuring the suction and exhaust efficiency.

[0037] Furthermore, in the embodiment of the present invention, the first stopper lug 20 is an arc-shaped structure having a first recessed portion. The first stopper lug 20 has a first arc edge and a second arc edge. The first arc edge is connected to the edge of the first through hole 15, and the ends of the second arc edge are respectively connected to the ends of the first arc edge. The height of the second arc edge is less than the height of the center of the first through hole 15. It can be understood that the second arc edge of the first stopper lug 20 is separated from the edge of the first through hole 15, and the height of the second arc edge is less than the height of the center of the first through hole 15. Thus, the first recessed portion of the first stopper lug 20 and the first through hole 15 form a first upwardly inclined flow guide. The first recessed portion causes high-speed gas entering the first through hole 15 to be discharged in an upwardly inclined direction, rather than in an axial direction. This allows the high-speed gas passing through the first through hole 15 to collide with the top of the inner wall of the horizontal liquid reservoir 30, effectively increasing the impact surface of the liquid refrigerant in the high-speed gas and thereby improving the sedimentation effect of the liquid refrigerant.

[0038] like Figure 4 and Figure 6As shown, in some embodiments of the present invention, a second stopper lug 21 extends from the edge of each second through hole 16 toward the leeward side 12. The second stopper lug 21 and the second through hole 16 to which it is connected form a second air guide opening with an upwardly inclined diversion direction. Furthermore, in these embodiments, the second stopper lug 21 is an arc-shaped structure having a second recessed portion. The second stopper lug 21 has a third arc edge and a fourth arc edge. The third arc edge is connected to the edge of the second through hole 16. The ends of the fourth arc edge are respectively connected to the ends of the third arc edge. The height of the fourth arc edge is less than the height of the center of the second through hole 16. It can be understood that the fourth arc edge of the second stopper ear 21 is separated from the edge of the second through hole 16, and the height of the fourth arc edge is less than the height of the center of the second through hole 16. In this way, the second recessed portion of the second stopper ear 21 and the first through hole 15 form a second upwardly inclined flow guide. Under the action of the second recessed portion, the high-speed gas entering the second through hole 16 is no longer discharged in the axial direction, but is discharged upwardly inclined. As a result, the high-speed gas passing through the second through hole 16 can impact the top of the inner wall of the horizontal liquid reservoir 30, thereby effectively increasing the impact surface of the liquid-phase refrigerant in the high-speed gas and improving the sedimentation effect of the liquid-phase refrigerant. In other words, in these embodiments, the design of the first stopper ear 20 and the second stopper ear 21 can further improve the sedimentation effect of the liquid-phase refrigerant in the horizontal liquid reservoir 30 and effectively ensure the suction and exhaust efficiency of the horizontal liquid reservoir 30.

[0039] like Figure 5 and Figure 6 As shown, in some embodiments of the present invention, a lower communicating hole 18 is provided through the lower half of the liquid retaining filter disc 10. The lower communicating hole 18 is in an arc shape. It can be understood that in these embodiments, the lower communicating hole 18 can further improve the suction and exhaust efficiency of the horizontal liquid reservoir 30.

[0040] like Figure 7 As shown, in some embodiments of the present invention, a plurality of third through holes 17 are provided through the lower half of the liquid-blocking filter disc 10, and the plurality of third through holes 17 and the plurality of second through holes 16 are evenly distributed in the circumferential direction. It can be understood that in these embodiments, the second through holes 16 and the third through holes 17 are located between the outer periphery of the liquid-blocking filter disc 10 and the liquid-blocking diversion portion 14, and by increasing the design of the through holes, the air intake and exhaust efficiency of the horizontal liquid reservoir 30 can be further improved. Furthermore, in these embodiments, the size of the third through hole 17 is the same as that of the second through hole 16, and a third stop ear is provided on the side of each third through hole 17 located on the leeward side 12. The structure of the third stop ear is the same as that of the second stop ear 21, and the structure of the third stop ear will not be repeated here.

[0041] In some embodiments of the present invention, the flange portion 13 is an annular structure, and the inner peripheral wall of the flange portion 13 is connected to the outer peripheral wall of the liquid retaining filter disc 10. It can be understood that in these embodiments, the annular structure of the flange portion 13 is used to enable the liquid retaining filter disc 10 to be more tightly and firmly connected to the inner wall of the horizontal liquid reservoir 30 through the flange portion 13.

[0042] In some embodiments of the present invention, the diameter of the first through hole 15 is 20 mm, and the diameter of each of the second through holes 16 is 11 mm.

[0043] See also Figures 8 to 11 The second aspect of the embodiment of the present invention provides a horizontal liquid reservoir 30, including the liquid-blocking filter disc 10 for the horizontal liquid reservoir 30 described in any of the above embodiments, and also including a liquid reservoir shell 31 and a liquid-blocking part 35. The axis of the liquid reservoir shell 31 is arranged horizontally, and an air inlet 32 ​​is provided at one end of the liquid reservoir shell 31. The outer peripheral wall of the liquid-blocking part 35 is fixedly connected to the inner peripheral wall of the liquid reservoir shell 31. The liquid-blocking filter disc 10 is arranged inside the liquid reservoir shell 31, and the liquid-blocking filter disc 10 is located between the liquid-blocking part 35 and the air inlet 32. A fourth through hole is provided through the lower half of the liquid-blocking part 35, and at least a part of the liquid-blocking part 35 is located in the diversion direction of the first diversion port. According to the horizontal liquid reservoir 30 of the embodiment of the present invention, on the basis of ensuring the suction and exhaust efficiency, it can effectively reduce the liquid backflow phenomenon, improve the performance of the compressor, improve the flow pulsation and reduce the noise.

[0044] Furthermore, in the embodiment of the present invention, the horizontal liquid reservoir 30 further includes an air inlet pipe 33 and an exhaust pipe 34. The air inlet pipe 33 is arranged in communication with the air inlet 32. One end of the exhaust pipe 34 extends from the bottom of the liquid reservoir housing 31. The end of the exhaust pipe 34 extending into the liquid reservoir housing 31 is arranged near the inner top of the liquid reservoir housing 31, and the pipe of the exhaust pipe 34 extending into the liquid reservoir housing 31 is located on the side of the liquid blocking member 35 away from the liquid blocking filter disc 10. It can be understood that in the embodiment of the present invention, the liquid blocking filter disc 10 divides the interior of the liquid reservoir housing 31 into an air inlet chamber and an exhaust chamber along the axial direction. The air inlet pipe 33 is connected to the air inlet chamber, and the exhaust pipe 34 is connected to the exhaust chamber. Moreover, through the ingenious design that at least a part of the liquid blocking member 35 is located in the guide direction of the first guide port, when the high-speed gas enters the exhaust chamber from the first through hole 15, a part of the gas impacts the inner top of the liquid reservoir shell 31, and another part of the gas can impact the liquid blocking member 35, thereby effectively increasing the impact surface of the liquid-phase refrigerant, thereby improving the sedimentation effect of the liquid-phase refrigerant.

[0045] like Figure 12 and Figure 13 The following are two simulation vector diagrams of the horizontal liquid storage device according to the embodiment of the present invention. Figure 12 and 13 It can be seen that the horizontal liquid storage device of the embodiment of the utility model can effectively improve the liquid return effect by structurally improving the liquid blocking filter plate and coordinating the ingenious design of the liquid blocking parts, while ensuring the efficiency of the refrigerant flux, thereby effectively improving the performance of the compressor.

[0046] A third aspect of the present invention provides a compressor comprising the horizontal liquid accumulator 30 described in any of the above embodiments. The compressor according to the present invention can effectively reduce liquid return, improve compressor performance, improve flow pulsation, and reduce noise while ensuring suction and exhaust efficiency.
