Description

Technical Field

[0001] This utility model relates to the field of refrigeration system technology, specifically to a vapor-liquid separation filter for a refrigeration system. Background Technology

[0002] A vapor-liquid separator filter in a refrigeration system is used to separate the refrigerant in two states: liquid and gas. Liquid and gas have different densities and flow properties. The vapor-liquid separator filter can separate the liquid and gas, ensuring that the liquid enters the appropriate place in the refrigeration system while the gas is discharged outside the system.

[0003] For example, a refrigeration system vapor-liquid separation filter with publication number CN204648778U solves the problems of liquid slugging at startup, high manufacturing cost, complex installation, and large space occupation by combining the filter and the vapor-liquid separator into one and adding a return liquid control valve.

[0004] During use, the above devices separate gas and liquid by gravity after they enter the filter. This method of separation by gravity is inefficient and requires a lot of space. As the gas and liquid enter, the filter element filters out impurities. Over a long period of time, the filtration effect of the filter element will gradually decrease, eventually causing the filter element to be completely blocked by impurities and unable to continue filtering. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a vapor-liquid separation filter for a refrigeration system. When separating vapor and liquid, the separation efficiency is accelerated by the combined action of gravity and centrifugal force. At the same time, the internal filter screen can be cleaned to prevent clogging.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a vapor-liquid separation filter for a refrigeration system, comprising a filter cylinder, a baffle plate disposed inside the filter cylinder, and a separation component disposed inside the filter cylinder, the separation component being used to separate vapor and liquid during refrigeration;

[0009] The separation assembly includes a motor mounted on a partition, a rotating shaft mounted on one side of the motor, a separation chamber mounted on the other side of the rotating shaft, an annular plate mounted inside the separation chamber, an array of sealing gaskets mounted on the outside of the annular plate, and a telescopic spring rod mounted on the other side of the sealing gasket.

[0010] Preferably, a spherical block is provided at the end of the telescopic spring rod away from the sealing gasket, and the separation chamber is provided with an array of mating grooves, which are slidably connected to the spherical block. An oblique groove is provided on the side of the separation chamber perpendicular to the mating groove, and the oblique groove is slidably connected to the sealing gasket.

[0011] Preferably, the separation chamber is provided with an air inlet pipe on the side away from the motor, and a cleaning component is provided on the outside of the air inlet pipe.

[0012] Preferably, the cleaning assembly includes a support plate disposed on the side of the separation chamber near the air intake pipe, a limiting rod disposed on the support plate, a circulating cam disposed on the limiting rod, a cleaning plate disposed inside the circulating cam, a collection pipe disposed inside the cleaning plate, and a collection chamber disposed on the collection pipe.

[0013] Preferably, the circulating cam has a fixing rod inside, and the collecting pipe has a valve.

[0014] Preferably, the filter cylinder is provided with a gas-liquid mixture inlet pipe, the filter cylinder is provided with a return steam pipe, and the return steam pipe is engaged and slidably connected with the fixed rod. The return steam pipe is provided with oil atomization holes, and the filter cylinder is provided with an annular groove, and the annular groove is slidably connected with the separation chamber.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This new invention utilizes the separation component to initially separate gas and liquid when they enter the filter cartridge due to gravity, followed by secondary separation under the centrifugal force of the separation component. This not only accelerates the separation efficiency between gas and liquid but also saves a lot of space, avoiding the filter cartridge from being too large and occupying too much space.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example 1

[0028] Please see Figures 1 to 5 The first embodiment of this utility model provides a technical solution: a vapor-liquid separation filter for a refrigeration system, including a filter cylinder 1, which is used to separate the vapor-liquid mixture. A baffle 13 is provided inside the filter cylinder 1, and a separation component 2 is provided inside the filter cylinder 1. The separation component 2 is used to separate the vapor and liquid in the refrigeration process.

[0029] The separation assembly 2 includes a motor 21 mounted on a partition 13, which drives a rotating shaft 22 to rotate. The rotating shaft 22 is located on one side of the motor 21, and a separation chamber 23 is located on the other side of the rotating shaft 22. The separation chamber 23 is conical in shape with sufficient internal cavity. Filter holes are provided near the rotating shaft 22 to allow the vapor-liquid mixture to smoothly enter the separation chamber 23. An annular plate 24, also equipped with filter holes, is located inside the separation chamber 23. This creates two spaces within the separation chamber 23; the middle space can temporarily store the liquid. Gas can smoothly enter the lower half of the filter cartridge 1 through the filter holes. The sealing gasket 25 is arranged on the outside of the annular plate 24. The sealing gasket 25 can adhere to the outer wall of the annular plate 24 without external force, forming a closed state. The sealing gasket 25 is arranged on the other side of the telescopic spring rod 26. The telescopic spring rod 26 is used to push the sealing gasket 25, so that the sealing gasket 25 can adhere to the annular plate 24. After the motor 21 is started, the entire separation chamber 23 will rotate. At this time, the centrifugal force generated will be greater than the pushing force of the telescopic spring rod 26, allowing gas to pass through the annular plate 24.

[0030] A spherical block 27 is provided at the end of the telescopic spring rod 26 away from the sealing gasket 25. The spherical block 27 is used to connect the telescopic spring rod 26 and the separation chamber 23. Under the action of the separation chamber 23, the sealing gasket 25 is moved. The separation chamber 23 has an array of mating grooves 231 inside, and the mating grooves 231 are slidably connected to the spherical block 27. The separation chamber 23 has an array of inclined grooves 232 on one side perpendicular to the mating grooves 231, and the inclined grooves 232 are slidably connected to the sealing gasket 25. The inclined grooves 232 are outwardly diffusing curved grooves to facilitate the movement of the sealing gasket 25.

[0031] An air inlet pipe 3 is provided on the side of the separation chamber 23 away from the motor 21. Several filter holes are opened on the surface of the air inlet pipe 3 so that gas can enter the interior of the return pipe 12 through the air inlet pipe 3. A cleaning component 4 is provided on the outside of the air inlet pipe 3. The cleaning component 4 is used to clean the impurities and fine liquid mist intercepted on the surface of the air inlet pipe 3 to avoid clogging of the air inlet pipe 3 after long-term use.

[0032] During operation, the gas-liquid mixture enters the filter cartridge 1 through the gas-liquid mixture inlet pipe 11. Under the weight of their own weight, the gas and liquid undergo initial separation. The liquid then enters the separation chamber 23. The motor 21 is then started, and the separation chamber 23 is rotated via the rotating shaft 22. The sealing gasket 25, which is slidably connected inside the separation chamber 23, will detach from the surface of the annular plate 24 under the action of centrifugal force, allowing the gas to smoothly enter the lower half of the filter cartridge 1 through the filter holes on the annular plate 24. At the same time, some liquid is also carried into the lower half of the filter cartridge 1 for storage. The remainder will continue to be stored inside the separation chamber 23 and enter the return gas pipe 12 through the inlet pipe 3, and be transported to the outside of the filter cartridge 1. When the entire filter cartridge 1 is stopped, the separation chamber 23 will no longer generate centrifugal force. At this time, the telescopic spring rod 26 will push the sealing gasket 25 to seal the annular plate 24, storing the remaining liquid in the separation chamber 23, thus completing the entire filtration process.

[0033] Example 2

[0034] Please see Figures 1 to 7 This is the second embodiment of the present invention, which differs from the first embodiment in that:

[0035] The cleaning assembly 4 includes a support plate 41 disposed on the side of the separation chamber 23 near the intake pipe 3. The support plate 41 is used to support the circulation cam 43 via a limiting rod 42. The limiting rod 42 disposed on the support plate 41 is used to cooperate with the circulation groove on the circulation cam 43 to drive the circulation cam 43 to rise and fall. The circulation cam 43 disposed on the limiting rod 42 is used to rise and fall under the push of the limiting rod 42. A cleaning plate 44 disposed inside the circulation cam 43 is used to clean impurities and fine liquid mist adhering to the surface of the intake pipe 3 during the rise of the circulation cam 43. A collection pipe 45 disposed inside the cleaning plate 44 is slidably connected to the cleaning plate 44 for collection. A collection chamber 46 disposed on the collection pipe 45 is used to collect impurities cleaned by the cleaning plate 44.

[0036] The circulating cam 43 is equipped with a fixing rod 431 inside. The fixing rod 431 is used to limit the lifting and lowering of the circulating cam 43 to prevent the circulating cam 43 from rotating under the drive of the limiting rod 42. The collection pipe 45 is equipped with a valve 451 for opening and closing to process the collected impurities.

[0037] The filter cylinder 1 is provided with a gas-liquid mixture inlet pipe 11, and a return steam pipe 12 is provided inside the filter cylinder 1. The return steam pipe 12 is engaged and slidably connected with the fixed rod 431. The return steam pipe 12 is used to transport the separated gas to the outside of the filter cylinder 1. The return steam pipe 12 is provided with an oil atomization hole 121. The oil atomization hole 121 is used to atomize the liquid below the filter cylinder 1, so that it can enter other devices through the return steam pipe 12. The filter cylinder 1 is provided with an annular groove 14, and the annular groove 14 is slidably connected with the separation chamber 23.

[0038] During use, after the separation chamber 23 rotates, the limiting rod 42 on the support plate 41 connected to it will push the circulation cam 43 to reciprocate up and down on the surface of the circulation cam 43, thereby driving the cleaning plate 44 on the circulation cam 43 to approach the surface of the intake pipe 3 to clean it. The impurities that are cleaned will fall into the collection chamber 46 on the collection pipe 45 below the cleaning plate 44, and then be discharged outside the filter cartridge 1 through the collection pipe 45, thus avoiding long-term filtration blockage of the entire intake pipe 3.

[0039] The remaining structure is the same as that in Example 1.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
