Description
Technical Field
[0001] The utility model relates to the technical field of compressors, in particular to a filter screen assembly for a liquid receiver, a liquid receiver having the same, and a compressor. Background Art
[0002] As an important component of a compressor, the main function of the liquid receiver is to separate the liquid-phase and gas-phase refrigerants, store the liquid-phase refrigerant at the bottom and wait for it to be converted into a gas phase, so as to prevent the abnormal condition of the liquid refrigerant entering the compressor pump body and causing the liquid refrigerant to knock the cylinder, resulting in damage to the compressor pump body.
[0003] According to the installation direction, the liquid receiver can be divided into two types: vertical and horizontal. Among them, the horizontal liquid receiver is installed horizontally, and its axis is usually flush with the horizontal plane. Due to the horizontal layout of the horizontal liquid receiver, there will be problems such as a small sedimentation space and a short sedimentation distance for the liquid refrigerant contained in the low-temperature and low-pressure refrigerant inhaled by the compressor in the liquid receiver, resulting in a liquid return problem, which leads to adverse phenomena such as liquid hammer and over-compression. To solve the liquid return problem, a common method is to add a simple baffle inside the liquid receiver housing, but this will reduce the refrigerant flow rate in the liquid receiver, affect the suction and exhaust efficiency of the liquid receiver, and lead to a reduction in compression efficiency. Summary of the Utility Model
[0004] Based on this, the purpose of the utility model is to overcome the deficiencies of the prior art, and provide a filter screen assembly for a liquid receiver, which is used to be assembled in the liquid receiver. On the basis of ensuring the refrigerant flux, it can promote the sedimentation of the liquid-phase refrigerant, effectively reduce the liquid return phenomenon, and improve the performance of the compressor.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:
[0006] A filter screen assembly for a liquid receiver, the filter screen assembly includes a horizontal plate, an upper surrounding plate, a filter disk, and a liquid baffle. The horizontal plate is used to be installed inside the liquid receiver, and the length direction of the horizontal plate is parallel to the axial direction of the liquid receiver; the upper surrounding plate is arranged at the top of one end of the horizontal plate, the filter disk and the liquid baffle are respectively arranged at intervals at the bottom of the horizontal plate, and the filter disk is provided with ventilation holes through it, and the liquid baffle is provided with refrigerant channels through it.
[0007] Thus, for the liquid storage filter assembly according to the embodiments of the present utility model, which is used to be assembled in a liquid storage device, the transverse plate is used to be horizontally installed inside the liquid storage device, dividing the interior of the liquid storage device into an upper chamber and a lower chamber, and the upper chamber of the liquid storage device near one end of the intake pipe is closed by the upper enclosure plate. The filter disk and the liquid baffle plate respectively extend into the lower chamber. In this way, the refrigerant entering the interior of the liquid storage device from the intake pipe first enters the lower chamber, and successively passes through the blocking and filtering of the filter disk and the liquid baffle plate, so that the liquid-phase refrigerant can be fully settled, and then moves along the intake direction to one end of the liquid storage device away from the intake pipe and enters the upper chamber, and finally is discharged through the exhaust pipe in the upper chamber. Therefore, for the liquid storage filter assembly according to the embodiments of the present utility model, on the basis of ensuring the refrigerant flux, it can promote the settlement of the liquid-phase refrigerant, effectively reduce the liquid return phenomenon, and improve the performance of the compressor.
[0008] As an implementation manner, the filter assembly further includes a lower baffle plate, and the lower baffle plate is arranged at the bottom of one end of the transverse plate away from the upper enclosure plate.
[0009] As an implementation manner, the upper enclosure plate is vertically arranged upward on the top of the transverse plate, the filter disk is vertically arranged downward on the bottom of the transverse plate, the height of the upper enclosure plate is H, the height of the filter disk is L, and H≤0.5L.
[0010] As an implementation manner, the liquid baffle plate is located between the filter disk and the lower baffle plate, and the height of the lower baffle plate is less than the height of the liquid baffle plate.
[0011] As an implementation manner, the middle part of the filter disk bulges towards the side away from the liquid baffle plate along the length direction of the transverse plate to form a spherical flow guiding part, and a plurality of ventilation holes are formed in the filter disk, and the plurality of ventilation holes are distributed around the spherical flow guiding part.
[0012] As an implementation manner, the total area of the plurality of ventilation holes is S, and the area of the refrigerant passage is D, and S≤D.
[0013] As an implementation manner, an annular fixing part is coaxially arranged on the outer periphery of the filter disk.
[0014] As an implementation manner, the transverse plate is a rectangular plate-like structure.
[0015] Another aspect of the embodiment of the present utility model provides a liquid reservoir, which includes a liquid reservoir housing and the liquid reservoir filter screen assembly described in any of the above embodiments. The liquid reservoir housing is a cavity structure with a hollow interior. One end of the liquid reservoir housing is coaxially connected with an air inlet pipe. The cross plate is horizontally installed inside the liquid reservoir housing along the axial direction, and both ends of the cross plate are spaced from both ends of the liquid reservoir housing respectively, so that the interior of the liquid reservoir housing is divided into an upper chamber and a lower chamber. One end of the upper surrounding plate is close to the air inlet pipe, and the outer peripheral wall of the upper surrounding plate abuts against the inner wall of the liquid reservoir housing, so that one end of the upper chamber close to the air inlet pipe is closed. An exhaust pipe is communicated with the upper chamber, and one end of the exhaust pipe extends out of the liquid reservoir housing.
[0016] Thus, for the liquid reservoir according to the embodiment of the present utility model, through the structural improvement of the filter screen assembly, the high-speed refrigerant coming in from the air inlet pipe will not directly rush towards the nozzle of the exhaust pipe. Under the action of the upper surrounding plate, the refrigerant first enters the lower chamber and is blocked and filtered by the filter disk and the liquid baffle in sequence, so that the liquid phase part in the refrigerant can be fully settled. Then the remaining refrigerant continues to move along the air inlet direction to the end of the liquid reservoir housing far from the air inlet pipe and impacts on the inner wall of the liquid reservoir housing. After that, it enters the upper chamber and is finally discharged into the exhaust pipe. Therefore, through the cooperative design between the liquid reservoir housing and the liquid reservoir filter screen assembly in the embodiment of the present utility model, the refrigerant path is extended as much as possible, and the filter disk, the liquid baffle below the cross plate 10 and the inner wall of the liquid reservoir housing cooperate to promote the settlement of the liquid phase refrigerant in sequence. On the basis of ensuring the refrigerant flux, the two-phase refrigerant can be prevented from directly rushing towards the nozzle of the exhaust pipe, thereby effectively reducing the liquid return phenomenon and improving the performance of the compressor.
[0017] Another aspect of the embodiment of the present utility model provides a compressor, which includes the liquid reservoir described in the above embodiment. Thus, for the compressor according to the embodiment of the present utility model, through the structural improvement of the filter screen assembly, on the basis of ensuring the refrigerant flux, the two-phase refrigerant can be prevented from directly rushing towards the nozzle of the exhaust pipe, and the settlement of the liquid phase refrigerant can be promoted, effectively reducing the liquid return phenomenon and improving the performance of the compressor.

Detailed implementation manners
[0030] To further illustrate each embodiment, the present utility model provides drawings. These drawings are a part of the disclosure of the present utility model, mainly used to illustrate the embodiments, and can be combined with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible embodiments and the advantages of the present utility model.
[0031] In the related art, liquid reservoirs can be divided into two types: vertical and horizontal. Among them, the horizontal liquid reservoir is installed horizontally, and its axis is usually flush with the horizontal plane. Since the horizontal liquid reservoir is horizontally arranged, there will be problems such as a small sedimentation space and a short sedimentation distance for the liquid refrigerant contained in the low-temperature and low-pressure refrigerant inhaled by the compressor in the liquid reservoir, resulting in a liquid return problem and causing adverse phenomena such as liquid hammer and over-compression. To solve the liquid return problem, a common method is to add a simple baffle inside the liquid reservoir housing, but this will reduce the refrigerant flow rate in the liquid reservoir, affect the suction and exhaust efficiency of the liquid reservoir, and lead to a reduction in compression efficiency.
[0032] In view of this, the embodiments of the present utility model provide a filter screen assembly for a liquid storage device, a liquid storage device having the same, and a compressor. By improving the structure of the filter screen assembly, on the basis of ensuring the refrigerant flux, it is possible to prevent the two-phase refrigerant from directly hitting the pipe orifice of the exhaust pipe, and to promote the sedimentation of the liquid-phase refrigerant, effectively reducing the liquid return phenomenon and improving the performance of the compressor.
[0033] Please refer to Figure 1 and Figure 2 , the first aspect of the embodiments of the present utility model provides a filter screen assembly for a liquid storage device. The filter screen assembly includes a horizontal plate 10, an upper surrounding plate 11, a filter disk 12, and a liquid baffle 13. The horizontal plate 10 is used to be installed inside the liquid storage device, and the length direction of the horizontal plate 10 is parallel to the axial direction of the liquid storage device; the upper surrounding plate 11 is arranged at the top of one end of the horizontal plate 10, and the filter disk 12 and the liquid baffle 13 are respectively arranged at intervals at the bottom of the horizontal plate 10, and the filter disk 12 is provided with vent holes 15 through it, and the liquid baffle 13 is provided with a refrigerant passage through it.
[0034] Furthermore, the filter screen assembly further includes a lower baffle 14, and the lower baffle 14 is arranged at the bottom of the end of the horizontal plate 10 away from the upper surrounding plate 11.
[0035] Thus, for the liquid storage device filter screen assembly according to the embodiments of the present utility model, which is used for being assembled in the liquid storage device, the horizontal plate 10 is used for horizontally bridging inside the liquid storage device, dividing the inside of the liquid storage device into an upper chamber and a lower chamber, and closing one end of the upper chamber of the liquid storage device close to the intake pipe 24 through the upper surrounding plate 11. The filter disk 12 and the liquid baffle 13 respectively extend into the lower chamber. In this way, the refrigerant entering the inside of the liquid storage device from the intake pipe 24 first enters the lower chamber, and successively passes through the blocking and filtering of the filter disk 12 and the liquid baffle 13, so that the liquid-phase refrigerant can be fully sedimented, and then moves along the intake direction to the end of the liquid storage device away from the intake pipe 24 and enters the upper chamber, and finally is discharged through the exhaust pipe 30 in the upper chamber. Therefore, for the liquid storage device filter screen assembly according to the embodiments of the present utility model, on the basis of ensuring the refrigerant flux, it can promote the sedimentation of the liquid-phase refrigerant, effectively reduce the liquid return phenomenon, and improve the performance of the compressor.
[0036] In the embodiments of the present utility model, the upper surrounding plate 11 is vertically arranged upward at the top of the horizontal plate 10, the filter disk 12 is vertically arranged downward at the bottom of the horizontal plate 10, the height of the upper surrounding plate 11 is H, the height of the filter disk 12 is L, and H ≤ 0.5L. With such a structural design, the height of the filter disk 12 is at least twice that of the upper surrounding plate 11. In this way, when the liquid storage device filter screen assembly of the embodiments of the present utility model is assembled inside the liquid storage device, the height of the lower chamber separated by the horizontal plate 10 is at least twice that of the upper chamber, thereby increasing the volume of the lower chamber and being more convenient for the sedimentation of the liquid-phase refrigerant.
[0037] In the embodiment of the present utility model, the liquid baffle 13 is located between the filter mesh plate 12 and the lower baffle 14, and the height of the lower baffle 14 is less than that of the liquid baffle 13.
[0038] In order to facilitate the filter mesh plate 12 to better settle the liquid-phase refrigerant, a spherical diversion portion is formed by protruding the middle part of the filter mesh plate 12 toward the side away from the liquid baffle 13 along the length direction of the cross plate 10. A plurality of ventilation holes 15 are formed in the filter mesh plate 12, and the plurality of ventilation holes 15 are distributed around the spherical diversion portion.
[0039] In the embodiment of the present utility model, the total area of the plurality of ventilation holes 15 is S, and the area of the refrigerant passage 16 is D, and S ≤ D.
[0040] In some embodiments of the present utility model, an annular fixing portion is coaxially arranged on the outer periphery of the filter mesh plate 12. Thus, the filter mesh plate 12 can be abutted against the inner side wall of the liquid storage device through the fixing portion.
[0041] In some embodiments of the present utility model, the cross plate 10 is a rectangular plate-like structure. It should be understood that the cross plate 10 can also be a structure of other shapes and cannot be understood as being limited only to the above shape.
[0042] Next, in conjunction with Figure 1 and Figure 2 A filter mesh assembly for a liquid storage device according to a specific embodiment of the present utility model will be described in detail. It should be understood that the following description is only an exemplary illustration and cannot be understood as a limitation of the present utility model.
[0043] The filter mesh assembly of this embodiment includes a cross plate 10, an upper enclosing plate 11, a filter mesh plate 12, a liquid baffle 13, and a lower baffle 14. The cross plate 10 is used to be installed inside the liquid storage device, and the length direction of the cross plate 10 is parallel to the axial direction of the liquid storage device; the upper enclosing plate 11 is arranged at the top of one end of the cross plate 10, the filter mesh plate 12 and the liquid baffle 13 are respectively arranged at intervals at the bottom of the cross plate 10, and the filter mesh plate 12 is provided with ventilation holes 15 in a penetrating manner, and the liquid baffle 13 is provided with a refrigerant passage 16 in a penetrating manner; the lower baffle 14 is arranged at the bottom of the end of the cross plate 10 away from the upper enclosing plate 11.
[0044] In this embodiment, the upper enclosing plate 11 is vertically arranged upward at the top of the cross plate 10, the filter mesh plate 12 is vertically arranged downward at the bottom of the cross plate 10, the height of the upper enclosing plate 11 is H, the height of the filter mesh plate 12 is L, and H = 0.5L. In addition, a spherical diversion portion is formed by protruding the middle part of the filter mesh plate 12 toward the side away from the liquid baffle 13 along the length direction of the cross plate 10. A plurality of ventilation holes 15 are formed in the filter mesh plate 12, and the plurality of ventilation holes 15 are distributed around the spherical diversion portion. Further, the total area of the plurality of ventilation holes 15 is S, and the area of the refrigerant passage is D, and S = D.
[0045] In this embodiment, the liquid baffle 13 is located between the filter mesh plate 12 and the lower baffle 14, and the height of the lower baffle 14 is less than the height of the liquid baffle 13. Further, an annular fixing portion is coaxially provided on the outer periphery of the filter mesh plate 12, and the transverse plate 10 is a rectangular plate-like structure.
[0046] On the other hand, an embodiment of the present invention provides a liquid storage device, which includes a liquid storage device housing 20 and the filter assembly for the liquid storage device of any one of the above embodiments. The liquid storage device housing 20 is a cavity structure with a hollow interior. One end of the liquid storage device housing 20 is coaxially and communicatively provided with an intake pipe 24; the transverse plate 10 is horizontally installed inside the liquid storage device housing 20 along the axial direction, and both ends of the transverse plate 10 are spaced from both ends of the liquid storage device housing 20 respectively, so that the interior of the liquid storage device housing 20 is divided into an upper chamber and a lower chamber; the upper surrounding plate 11 is close to one end of the intake pipe 24, and the outer peripheral wall of the upper surrounding plate 11 abuts against the inner wall of the liquid storage device housing 20, so that one end of the upper chamber close to the intake pipe 24 is closed; an exhaust pipe 30 is communicatively provided in the upper chamber, and one end of the exhaust pipe 30 extends out of the liquid storage device housing 20.
[0047] Thus, for the liquid storage device according to the embodiment of the present invention, through the structural improvement of the filter assembly, the high-speed refrigerant coming in from the intake pipe 24 will not directly rush towards the pipe orifice of the exhaust pipe 30. Under the action of the upper surrounding plate 11, the refrigerant first enters the lower chamber, and successively passes through the blocking and filtering of the filter mesh plate 12 and the liquid baffle 13, so that the liquid phase part in the refrigerant can be fully settled. After that, the remaining refrigerant continues to move along the intake direction to one end of the liquid storage device housing 20 away from the intake pipe 24, and impacts on the inner wall of the liquid storage device housing 20. Then, it enters the upper chamber and is finally discharged into the exhaust pipe 30. Therefore, through the cooperative design between the liquid storage device housing 20 and the filter assembly for the liquid storage device in the embodiment of the present invention, the refrigerant path is extended as much as possible, and the filter mesh plate 12, the liquid baffle 13 under the transverse plate 10 and the inner wall of the liquid storage device housing 20 are cooperated to promote the settlement of the liquid-phase refrigerant in turn. On the basis of ensuring the refrigerant flux, the two-phase refrigerant can be prevented from directly rushing towards the pipe orifice of the exhaust pipe 30, thereby effectively reducing the liquid return phenomenon and improving the performance of the compressor.
[0048] In some embodiments of the present invention, the exhaust pipe 30 sequentially penetrates through the liquid storage device housing 20 and the transverse plate 10 and extends into the upper chamber, and the pipe orifice of the end of the exhaust pipe 30 extending into the upper chamber is spaced from the top of the liquid storage device housing 20. Among them, the pipe orifice of the end of the exhaust pipe 30 extending into the upper chamber is provided with an inclined cut 31. It can be understood that by designing the pipe orifice of the exhaust pipe 30 extending into the upper chamber as the inclined cut 31 in the embodiment of the present invention, the intake surface of the exhaust pipe 30 can be increased, and thus the intake efficiency of the exhaust pipe 30 can be improved.
[0049] In some embodiments of the present utility model, the liquid storage container housing 20 includes a cylindrical main body 21, a left end cover 22, and a right end cover 23. The cylindrical main body 21 is a cylindrical structure with openings at both ends. The left end cover 22 and the right end cover 23 are respectively hermetically covered on the openings at both ends of the cylindrical structure. The intake pipe 24 penetrates through the right end cover 23 and is connected to the interior of the cylindrical main body 21; the end face of the upper surrounding plate 11 is flush with the opening at one end of the liquid storage container housing 20 close to the intake pipe 24. It can be understood that the shape of the liquid storage container housing 20 of the present utility model adopts a conventional cylindrical structure, which is jointly formed by the cylindrical main body 21, the left end cover 22, and the right end cover 23. However, it should be noted that the liquid storage container housing 20 of the present utility model can also adopt other shapes, such as a cuboid shape, and it cannot be understood that only the above-mentioned cylindrical structure is limited.
[0050] In some embodiments of the present utility model, a refrigerant channel is formed between the bottom of the liquid baffle 13 and the inner bottom of the liquid storage container housing 20, and the filter mesh disk 12 abuts against the inner side wall of the liquid storage container housing 20 through its fixing part.
[0051] In some embodiments of the present utility model, the inner cavity volume of the liquid storage container housing 20 is V, and the volume enclosed by the filter mesh disk 12, the upper surrounding plate 11, and the end of the liquid storage container housing 20 provided with the intake pipe 24 is P, and P≥0.15V. It can be understood that the cavity enclosed by the filter mesh disk 12, the upper surrounding plate 11, and the end of the liquid storage container housing 20 provided with the intake pipe 24 in the embodiments of the present utility model is the first filtrate cavity. The refrigerant entering the interior of the liquid storage container housing 20 from the intake pipe 24 first enters the first filtrate cavity. In the embodiments of the present utility model, by designing the relationship between the volume P of the first filtrate cavity and the internal volume V of the liquid storage container housing 20 as P≥0.15V, it can not only effectively reduce the vortex phenomenon generated by the refrigerant at the intake end of the liquid storage container housing 20, but also ensure that the refrigerant has sufficient sedimentation space in the first filtrate cavity.
[0052] For the horizontal liquid storage device according to the embodiments of the present utility model, its refrigerant path is specifically as follows: The refrigerant first enters the interior of the liquid storage container housing 20 from the intake pipe 24, and then sequentially passes through the filter mesh disk 12, the liquid baffle 13, and the lower baffle 14 along the axial direction of the lower chamber, and then impacts on the inner wall of the end of the liquid storage container housing 20 far from the intake pipe 24. After the impact, the refrigerant can not only achieve the sedimentation of the liquid-phase refrigerant, but also flow upward into the upper chamber, and finally enter the exhaust pipe 30 from the inclined cut 31 of the exhaust pipe 30.
[0053] As Figure 10 shown, Figure 10It is a simulation analysis diagram of the refrigerant path of the horizontal liquid storage device according to an embodiment of the present utility model. Through the simulation analysis of the refrigerant path in the embodiment of the present utility model, it can be known that for the horizontal liquid storage device according to the embodiment of the present utility model, the sedimentation effect of the liquid-phase refrigerant can be effectively improved, thereby reducing the liquid return. At the same time, the gaseous refrigerant is guided to flow to ensure the refrigerant flux in the liquid storage device, so as to improve the compressor efficiency.
[0054] Another aspect of the embodiment of the present utility model provides a compressor, including the liquid storage device of the above embodiment. Thus, for the compressor according to the embodiment of the present utility model, through the structural improvement of the filter screen assembly, on the basis of ensuring the refrigerant flux, the two-phase refrigerant can be prevented from directly rushing towards the nozzle of the exhaust pipe 30, and the sedimentation of the liquid-phase refrigerant can be promoted, effectively reducing the liquid return phenomenon and improving the performance of the compressor.
[0055] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "left", "right", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.
[0056] The above embodiments only represent several implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the filter screen assembly for the liquid storage device of the utility model, the liquid storage device having the same, and the compressor. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
