Description

Technical Field

[0001] The utility model relates to the technical field of compressors, in particular to a horizontal liquid storage device with a filter disc and a compressor. 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 the bottom until it is converted into gas, thereby preventing the liquid refrigerant from entering the compressor pump body and causing the liquid to hit the cylinder body, leading to abnormal operating conditions that damage the compressor pump body.

[0003] Common liquid storage tanks are usually cylindrical structures, and can be divided into vertical liquid storage tanks and horizontal liquid storage tanks according to the installation method. Among them, the installation method of the horizontal liquid storage tank is to place it horizontally, and one end of it is coaxially connected to the suction pipe. However, due to its horizontal installation method, the sedimentation space of the liquid phase refrigerant inside it is reduced, which leads to a decrease in the sedimentation effect of the liquid phase refrigerant, and the problem of liquid return is prone to occur. Therefore, some manufacturers design a disc-shaped filter assembly near the suction pipe inside the liquid storage tank, and open an air hole near the upper edge of the filter assembly. In this way, the gas-liquid two-phase refrigerant entering from the suction pipe first hits the solid part of the filter assembly, and the liquid phase refrigerant settles after the collision, while the gas phase refrigerant passes through the air hole, thereby effectively improving the sedimentation effect of the liquid phase refrigerant. However, since the exhaust direction of the suction pipe in the axial direction is a solid structure that is directly opposite to the filter assembly, the gas phase refrigerant is prone to reflection after the collision, and the resistance of the gas phase refrigerant passing through the air hole increases, thereby reducing the working efficiency of the compressor. Utility Model Content

[0004] Based on this, the purpose of the utility model is to overcome the deficiencies of the prior art and provide a horizontal liquid storage tank with a filter disc, which has the advantages of simple structure, effective reduction of liquid return phenomenon, and high air suction efficiency.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A horizontal liquid reservoir with a filter disc, comprising a liquid reservoir shell and a filter disc, wherein an end cover is provided at one end of the liquid reservoir shell, an air intake pipe is connected to the end cover, and the axial length of the liquid reservoir shell is L; the filter disc is in the shape of a disc, is coaxially built into the liquid reservoir shell, and the axial spacing between the filter disc and the end cover is H, and H and L satisfy: H≥0.2L; a spherical surface is extended in the middle of the filter disc toward the direction of the air intake pipe, the spherical surface is coaxially arranged with the air intake pipe and the liquid reservoir shell, and a first through hole is penetrated on the spherical surface; a plurality of second through holes are penetrated on the filter disc, and the plurality of second through holes are arranged around the spherical surface.

[0007] Therefore, the utility model limits the axial distance between the filter disc and the end cover so that there is a sufficient spacing between the filter disc and the intake pipe, thereby preventing the filter disc from being too close to the intake pipe and resulting in insufficient space for refrigerant sedimentation, thereby effectively reducing the performance loss of the compressor caused by the liquid return phenomenon; further, the utility model sets a spherical surface in the middle of the filter disc, and makes the spherical surface coaxial with the intake pipe and the compressor casing, and at the same time opens a first through hole on the spherical surface. In this way, part of the refrigerant entering from the intake pipe can directly pass through the first through hole, thereby improving the ventilation performance of the filter disc, thereby reducing the intake resistance of the compressor and improving the performance of the compressor; in addition, the utility model distributes a plurality of second through holes around the outer periphery of the spherical surface, thereby further improving the ventilation performance of the filter disc, thereby reducing the intake resistance of the compressor and improving the performance of the compressor.

[0008] As an embodiment, the outer periphery of the filter disc is coaxially provided with an annular fixing portion, and the fixing portion is coaxially provided on the inner peripheral wall of the reservoir housing. Thus, the utility model provides an annular fixing portion to facilitate the connection and fixing between the filter disc and the reservoir housing.

[0009] As an implementation manner, the fixing portion and the inner peripheral wall of the reservoir housing are fixed together by welding.

[0010] As an implementation mode, the distances from the second through holes to the center of the filter disc are all equal, and an oil return hole is provided through the lower end of the filter disc. Therefore, the utility model provides an oil return hole at the lower end of the filter disc, so that the liquid phase refrigerant can be evenly distributed at the lower end of the entire reservoir housing, preventing the oil from accumulating in the space between the filter disc and the end cover, thereby causing the problem of deterioration of the compressor lubrication.

[0011] As an implementation mode, a plurality of third through holes are arranged at intervals at the connection between the filter disc and the fixing part, and the plurality of third through holes are all in a semicircular shape. Therefore, the utility model can further improve the ventilation performance of the filter disc by distributing a plurality of third through holes at the connection between the filter disc and the fixing part, thereby reducing the suction resistance of the compressor and improving the performance of the compressor.

[0012] As an implementation manner, half of the spherical surface penetrates to form the first through hole.

[0013] As an implementation manner, the first through hole is opened through the middle of the spherical surface, and the area of ​​the first through hole is smaller than the area of ​​the spherical surface.

[0014] As an implementation mode, a plurality of fourth through holes are spaced apart at the connection between the spherical surface and the filter disc. Thus, the utility model can further improve the ventilation performance of the filter disc by distributing a plurality of third through holes at the connection between the spherical surface and the filter disc, thereby reducing the suction resistance of the compressor and improving the performance of the compressor.

[0015] As an embodiment, a disc-shaped gas-liquid separation baffle is coaxially arranged inside the liquid storage housing, and a refrigerant channel is provided at the lower end of the gas-liquid separation baffle; the filter disc is located between the gas-liquid separation baffle and the end cover. Therefore, the utility model can further improve the sedimentation effect of the liquid phase refrigerant by arranging the gas-liquid separation baffle at the end of the filter disc facing away from the end cover.

[0016] In addition, the utility model also provides a compressor, which includes the horizontal liquid accumulator with the filter plate described above. The compressor of the utility model can effectively reduce the risk of liquid return and optimize the performance of the compressor by improving the structure of the horizontal liquid accumulator.

[0029] Common liquid storage tanks are usually cylindrical structures, and can be divided into vertical liquid storage tanks and horizontal liquid storage tanks according to the installation method. Among them, the installation method of the horizontal liquid storage tank is to place it horizontally, and one end of it is coaxially connected to the suction pipe. However, due to its horizontal installation method, the sedimentation space of the liquid phase refrigerant inside it is reduced, which leads to a decrease in the sedimentation effect of the liquid phase refrigerant, and the problem of liquid return is prone to occur. Therefore, some manufacturers design a disc-shaped filter assembly near the suction pipe inside the liquid storage tank, and open an air hole near the upper edge of the filter assembly. In this way, the gas-liquid two-phase refrigerant entering from the suction pipe first hits the solid part of the filter assembly, and the liquid phase refrigerant settles after the collision, while the gas phase refrigerant passes through the air hole, thereby effectively improving the sedimentation effect of the liquid phase refrigerant. However, since the exhaust direction of the suction pipe in the axial direction is a solid structure that is directly opposite to the filter assembly, the gas phase refrigerant is prone to reflection after the collision, and the resistance of the gas phase refrigerant passing through the air hole increases, thereby reducing the working efficiency of the compressor.

[0030] In view of this, an embodiment of the utility model provides a horizontal liquid storage tank with a filter disc, which has the advantages of simple structure, effective reduction of liquid return phenomenon, high air suction efficiency, etc.

[0031] See also Figures 1 to 8 ; The embodiment of the utility model provides a horizontal liquid reservoir with a filter disc 20, including a liquid reservoir shell 10 and a filter disc 20. One end of the liquid reservoir shell 10 is provided with an end cover 11, and the end cover 11 is connected to an air intake pipe 12, and the axial length of the liquid reservoir shell 10 is L; the filter disc 20 is in the shape of a disc, and the filter disc 20 is coaxially built in the liquid reservoir shell 10, and the axial spacing between the filter disc 20 and the end cover 11 is H, and H and L satisfy: H≥0.2L; a spherical surface 21 extends from the middle part of the filter disc 20 toward the direction of the air intake pipe 12, and the spherical surface 21 is coaxially arranged with the air intake pipe 12 and the liquid reservoir shell 10, and a first through hole 22 is opened through the spherical surface 21.

[0032] Therefore, the embodiment of the utility model limits the axial distance between the filter disc 20 and the end cover 11 so that there is a sufficient spacing between the filter disc 20 and the intake pipe 12, thereby preventing the filter disc 20 from being too close to the intake pipe 12 and resulting in insufficient space for refrigerant sedimentation, thereby effectively reducing the performance loss of the compressor caused by the liquid return phenomenon; further, the embodiment of the utility model sets a spherical surface 21 in the middle of the filter disc 20, and makes the spherical surface 21 coaxial with the intake pipe 12 and the compressor housing, and at the same time opens a first through hole 22 on the spherical surface 21. In this way, part of the refrigerant coming in from the intake pipe 12 can directly pass through the first through hole 22, thereby improving the ventilation performance of the filter disc 20, thereby reducing the intake resistance of the compressor and improving the performance of the compressor.

[0033] Furthermore, a disc-shaped gas-liquid separation baffle 30 is coaxially arranged inside the liquid storage housing 10 of the embodiment of the utility model, and a refrigerant channel 31 is provided at the lower end of the gas-liquid separation baffle 30; the filter plate 20 is located between the gas-liquid separation baffle 30 and the end cover 11. Therefore, the embodiment of the utility model can further improve the sedimentation effect of the liquid phase refrigerant by arranging the gas-liquid separation baffle 30 at the end of the filter plate 20 facing away from the end cover 11.

[0034] In order to improve the ventilation performance of the horizontal liquid storage device, in the embodiment of the utility model, a plurality of second through holes 23 are formed through the filter plate 20, and the plurality of second through holes 23 are arranged around the spherical surface 21, and the distances from each second through hole 23 to the center of the filter plate 20 are equal. The utility model can further improve the ventilation performance of the filter plate 20 by distributing a plurality of second through holes 23 around the outer periphery of the spherical surface 21, thereby reducing the suction resistance of the compressor and improving the performance of the compressor.

[0035] Furthermore, the connection between the filter disc 20 and the fixing part 26 of the utility model embodiment is provided with a plurality of third through holes 24 at intervals, and the plurality of third through holes 24 are all in a semicircular shape. Therefore, the utility model can further improve the ventilation performance of the filter disc 20 by distributing a plurality of third through holes 24 at the connection between the filter disc 20 and the fixing part 26, thereby reducing the suction resistance of the compressor and improving the performance of the compressor.

[0036] Optionally, an oil return hole 27 is formed through the lower end of the filter disc 20. In the embodiment of the utility model, the oil return hole 27 is provided at the lower end of the filter disc 20 so that the liquid refrigerant can be evenly distributed in the lower end of the entire reservoir housing 10, thereby preventing oil from accumulating in the space between the filter disc 20 and the end cover 11, thereby causing the problem of deterioration of compressor lubrication.

[0037] In some embodiments of the present invention, an annular fixing portion 26 is coaxially provided on the outer periphery of the filter disc 20, and the fixing portion 26 is coaxially provided on the inner peripheral wall of the reservoir housing 10. Thus, the present invention facilitates the connection and fixation between the filter disc 20 and the reservoir housing 10 by providing an annular fixing portion 26. For example, the fixing portion 26 and the inner peripheral wall of the reservoir housing 10 are fixed together by welding.

[0038] like Figure 3 to Figure 4 As shown, in some embodiments of the present invention, half of the spherical surface 21 penetrates to form the first through hole 22 .

[0039] like Figures 7 and 8 As shown, in some embodiments of the present invention, the first through hole 22 is opened through the middle of the spherical surface 21 , and the area of ​​the first through hole 22 is smaller than the area of ​​the spherical surface 21 .

[0040] In addition, the utility model further provides a compressor, which includes the above-mentioned horizontal liquid accumulator with the filter plate 20. The compressor of the utility model can effectively reduce the risk of liquid return and optimize the performance of the compressor by improving the structure of the horizontal liquid accumulator.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model of the horizontal liquid storage tank and compressor with a filter plate. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
