Description

Technical Field

[0001] This invention relates to the field of compressor technology, and in particular to a horizontal liquid receiver and compressor. Background Technology

[0002] A rotary compressor works by using a slider to divide the cylinder into an intake chamber and an exhaust chamber. When the motor is energized, the stator coil generates an electromagnetic field, and the rotor cuts magnetic lines of force to drive the crankshaft of the pump body to rotate, causing the piston to rotate within the cylinder and compress the refrigerant. Under the action of the crankshaft, the volume of the intake and exhaust chambers is continuously changed, drawing in low-temperature, low-pressure gaseous refrigerant, compressing it into high-temperature, high-pressure gaseous refrigerant, and then expelling it from the pump body, thus completing the cycle.

[0003] Based on the installation direction, compressors can be classified into vertical and horizontal types. Horizontal compressors use a horizontally installed liquid receiver. This installation method significantly reduces the settling space inside the horizontal liquid receiver, which can easily lead to severe liquid return after intake due to the small settling space and short settling distance. Severe liquid return can cause liquid slugging and over-compression of the pump, thereby reducing compressor performance. Summary of the Invention

[0004] Based on this, the purpose of the present invention is to overcome the shortcomings of the prior art and provide a horizontal liquid receiver and compressor. According to the embodiments of the present invention, the horizontal liquid receiver and compressor can effectively improve the settling effect of liquid refrigerant, thereby reducing liquid return, effectively improving adverse phenomena such as liquid slugging and over-compression, and ensuring the performance of the compressor.

[0005] To achieve the above objectives, a first aspect of the present invention provides a horizontal liquid receiver, including a receiver housing and a flow-guiding and liquid-blocking assembly. The receiver housing is a cylindrical structure with one open end, and an air inlet pipe is coaxially connected to the open end of the receiver housing. The flow-guiding and liquid-blocking assembly includes a fixed bracket and a flow-guiding and liquid-blocking wheel. The fixed bracket is connected to the inner wall of the receiver housing. The flow-guiding and liquid-blocking wheel includes a rotating sleeve and a plurality of flow-guiding and liquid-blocking plates disposed on the outer wall of the rotating sleeve. The rotating sleeve is rotatably mounted on the fixed bracket. The plurality of flow-guiding and liquid-blocking plates are circumferentially distributed on the rotating sleeve, and a channel for refrigerant to pass through is formed between two adjacent flow-guiding and liquid-blocking plates.

[0006] Therefore, the horizontal liquid receiver according to the present invention, by adding a flow-guiding and liquid-blocking assembly inside the receiver housing, and utilizing the characteristic that the flow-guiding and liquid-blocking wheels can be freely rotated on the fixed support, allows the flow-guiding and liquid-blocking plates to adaptively balance their rotation speed according to the airflow size when impacted by the high-speed airflow blown in from the inlet pipe, without the need for an additional power unit. This reduces the agitation of the liquid at the bottom of the horizontal liquid receiver. Furthermore, the flow-guiding and liquid-blocking plates also promote the settling of the liquid refrigerant. Specifically, the force-bearing surfaces of the flow-guiding and liquid-blocking plates cause the liquid refrigerant in the airflow to adhere and settle. Simultaneously, during rotation, the centrifugal force of the flow-guiding and liquid-blocking plates can also fling some of the liquid refrigerant impacting the flow-guiding and liquid-blocking plates onto the inner wall of the receiver housing, further enhancing the settling effect. In other words, the horizontal liquid receiver according to the present invention can effectively improve the settling effect of the liquid refrigerant, thereby reducing liquid return, effectively improving adverse phenomena such as liquid slugging and overcompression, and ensuring the performance of the compressor.

[0028] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention, primarily used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention.

[0029] In related technologies, the working principle of a rotary compressor is to use a slider to divide the cylinder into two spaces: an intake chamber and an exhaust chamber. When the motor is energized, the stator coil generates an electromagnetic field, and the rotor cuts magnetic lines of force to drive the crankshaft of the pump body to rotate, causing the piston to rotate within the cylinder and compress the refrigerant. Under the action of the crankshaft, the volume of the intake and exhaust chambers is continuously changed, drawing in low-temperature, low-pressure gaseous refrigerant, compressing it into high-temperature, high-pressure gaseous refrigerant, and then discharging it from the pump body, thus completing the cycle. Based on the installation direction, compressors can be classified into vertical and horizontal types. Horizontal compressors use a horizontally installed receiver. This installation method significantly reduces the settling space inside the receiver, easily leading to severe liquid backflow after intake due to the small settling space and short settling distance. Severe liquid backflow can cause liquid slugging and overcompression of the pump body, thereby reducing compressor performance.

[0030] In view of this, embodiments of the present invention provide a horizontal liquid receiver and a compressor. The horizontal liquid receiver and compressor of the present invention can effectively improve the settling effect of liquid refrigerant, thereby reducing liquid return, effectively improving adverse phenomena such as liquid slugging and over-compression, and ensuring the performance of the compressor.

[0031] Please see Figures 1 to 8The first aspect of this invention provides a horizontal liquid receiver, including a liquid receiver housing 10 and a flow guiding and blocking assembly 20. The liquid receiver housing 10 is a cylindrical structure with one open end, and an air inlet pipe 11 is coaxially connected to the open end of the liquid receiver housing 10. The flow guiding and blocking assembly 20 includes a fixed bracket 21 and a flow guiding and blocking wheel 25. The fixed bracket 21 is connected to the inner wall of the liquid receiver housing 10. The flow guiding and blocking wheel 25 includes a rotating sleeve 26 and a plurality of flow guiding and blocking plates 27 disposed on the outer wall of the rotating sleeve 26. The rotating sleeve 26 is rotatably mounted on the fixed bracket 21. The plurality of flow guiding and blocking plates 27 are circumferentially distributed on the rotating sleeve 26, and a channel for refrigerant to pass through is formed between two adjacent flow guiding and blocking plates 27.

[0032] Specifically, in this embodiment of the invention, the bottom of the reservoir housing 10 is connected to an exhaust pipe 12, one end of which is inserted into the interior of the reservoir housing 10 perpendicular to its axis. A fixed bracket 21 divides the interior of the reservoir housing 10 into an air inlet chamber 13 and an exhaust chamber 14. The exhaust pipe 12 is connected to both the air inlet chamber 13 and the exhaust chamber 14. Furthermore, the flow guide plate 27 has a spiral structure, and the edge of the flow guide plate 27 away from the rotating sleeve 26 has an arc-shaped structure.

[0033] Therefore, in the horizontal liquid receiver according to the embodiment of the present invention, by adding a flow guiding and liquid blocking assembly 20 inside the liquid receiver housing 10, and utilizing the characteristic that the flow guiding and liquid blocking wheel 25 can be freely rotatably mounted on the fixed support 21, the flow guiding and liquid blocking plates 27, when impacted by the high-speed airflow blown in from the air inlet pipe 11, can adaptively balance the rotation speed according to the size of the airflow without the need for an additional power device, thereby reducing the agitation of the liquid at the bottom of the horizontal liquid receiver. Furthermore, the flow guiding and liquid blocking plates 27 can also promote the sedimentation of the liquid refrigerant. Specifically, the force-bearing surface of the flow guiding and liquid blocking plates 27 is used to cause the liquid refrigerant in the airflow to adhere and settle. At the same time, during the rotation process, the centrifugal force of the flow guiding and liquid blocking plates 27 can also cause some of the liquid refrigerant impacting the flow guiding and liquid blocking plates 27 to be flung onto the inner wall of the liquid receiver housing 10, further increasing the sedimentation effect of the liquid refrigerant. In other words, the horizontal liquid receiver according to the embodiments of the present invention can effectively improve the settling effect of liquid refrigerant, thereby reducing liquid return, effectively improving adverse phenomena such as liquid slugging and overcompression, and ensuring the performance of the compressor.

[0034] To further improve the settling effect of liquid refrigerant, in this embodiment of the invention, a liquid-blocking filter disk 30 is coaxially arranged in the air inlet chamber 13. The liquid-blocking filter disk 30 is located between the flow guiding liquid-blocking assembly 20 and the air inlet pipe 11. The liquid-blocking filter disk 30 has a disc-shaped structure. The outer peripheral wall of the liquid-blocking filter disk 30 is connected to the inner peripheral wall of the liquid reservoir housing 10. The liquid-blocking filter disk 30 has several through holes in the axial direction for the refrigerant to pass through. In this embodiment of the invention, the high-speed airflow entering the liquid receiver housing 10 from the intake pipe 11 first impacts the liquid-blocking filter plate 30, causing some of the liquid refrigerant in the high-speed airflow to settle due to the obstruction of the liquid-blocking filter plate 30. The high-speed airflow passing through the liquid-blocking filter plate 30 then acts on the flow-guiding liquid-blocking assembly 20. Several flow-guiding liquid-blocking plates 27 rotate under the impact of the high-speed airflow, causing some of the liquid refrigerant impacting the plates 27 to adhere and settle, while some is flung off and impacts the inner wall of the liquid receiver housing 10 for settling. In other words, this embodiment of the invention uses the liquid-blocking filter plate 30 to perform initial settling of the liquid refrigerant in the high-speed airflow, and then uses the flow-guiding liquid-blocking assembly 20 to further settle the high-speed airflow, resulting in a more thorough settling effect for the liquid refrigerant. This effectively improves adverse phenomena such as liquid slugging and over-compression, ensuring the performance of the compressor.

[0035] Optionally, in some embodiments of the present invention, the fixed bracket 21 includes a ring 22 and a connecting frame 23. The outer peripheral wall of the ring 22 is connected to the inner peripheral wall of the liquid reservoir housing 10. The connecting frame 23 is connected to the inner peripheral wall of the ring 22, and the center of the connecting frame 23 overlaps with the center of the ring 22. The center of the connecting frame 23 extends along the axial direction of the liquid reservoir housing 10 toward one end of the air inlet pipe 11 to form a central shaft 24. The rotating sleeve 26 is rotatably mounted on the central shaft 24.

[0036] Furthermore, in these embodiments, the connecting frame 23 includes three connecting tubes, with one end of each tube fixedly connected to the central shaft 24, and the other ends of each tube fixed to the inner circumferential wall of the ring 22, with an included angle of 120° between adjacent connecting tubes. Additionally, in these embodiments, the rotating sleeve 26 has a cylindrical structure, with a shaft hole extending through its center along its axial direction, and the shaft hole is movably fitted onto the central shaft 24. To prevent the rotating sleeve 26 from detaching from the central shaft 24 during rotation, one end of the central shaft 24 away from the connecting frame 23 extends beyond the rotating sleeve 26, and the portion of the central shaft 24 extending beyond the rotating sleeve 26 is detachably connected to a limiting component. This limiting component can be a nut, with an external thread at the end of the central shaft 24 for easy screwing in.

[0037] Optionally, in some embodiments of the present invention, the maximum width of the flow guide plate 27 in the axial direction is L, where L ≥ 9.5 mm; the distance between the end of the flow guide plate 27 away from the rotating sleeve 26 and the ring 22 is d, where 1 mm ≤ d ≤ 2 mm; and the thickness of the flow guide plate 27 is greater than or equal to 2.5 mm.

[0038] Optionally, in some embodiments of the present invention, the flow guide and liquid baffle 27 is made of iron material, and the side of the flow guide and liquid baffle 27 facing the air inlet pipe 11 has a frosted surface. The rough frosted surface can improve the adhesion of the liquid refrigerant, thereby effectively improving the sedimentation effect of the liquid refrigerant. In addition, the number of flow guide and liquid baffle 27 is 5 to 8.

[0039] Please see Figure 9 , Figure 9 This is a simulation vector diagram of the horizontal liquid reservoir according to an embodiment of the present invention. From... Figure 9 As can be seen, the horizontal liquid receiver of this embodiment of the invention, by setting the flow guiding and liquid blocking component 20 inside the liquid receiver housing 10, can greatly reduce the amount of liquid refrigerant discharged from the exhaust pipe 12, effectively reduce liquid return, thereby effectively improving adverse phenomena such as liquid slugging and overcompression, and ensuring the performance of the compressor.
