Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of refrigeration devices, more particularly, to a scroll refrigeration compressor. BACKGROUND

[0002] The scroll refrigeration compressor is a type of compressor used in refrigeration and air conditioning systems; it is also known as a scroll compressor, scroll axial flow compressor or spiral compressor; the main components of the scroll compressor are a rotating impeller and a stationary spiral ring, when the compressor is running, the rotating impeller rotates in the spiral ring, so that the gas or steam is compressed; the advantages of the scroll compressor include high efficiency, small size, low vibration and noise, smooth operation, etc.

[0003] When the compressor is used in a humid environment, it causes the compression equipment and air moving machinery to be prone to rust, shortens the service life, increases maintenance costs, and the water in the air mixes with the lubricating oil during the compression process, which reduces the lubricating efficiency and increases the wear of the parts, when the temperature is low, the water will freeze on the inner wall of the air pipe, thereby reducing the pipe diameter, and even causing blockage, affecting the operation of the compressor.

[0004] The Chinese patent with the authorized publication number CN113202749B discloses a scroll refrigeration compressor, by setting a dehumidification module, entering into the air inlet pipe through the air inlet hole of the pipe cover, the desiccant absorbs and filters the water vapor in the air, reduces the water content in the air, improves the air intake effect of the compressor, reduces the energy consumption of the compressor, saves the use cost, prevents the compression equipment and air moving machinery from rusting, prolongs the service life, reduces the maintenance cost, improves the lubricating efficiency, reduces the wear of the parts, and creates a good operating environment for the compressor.

[0005] Although the above-mentioned patent can improve the service life of the device to a certain extent, it still has certain limitations, a small amount of high-pressure refrigerant will flow back into the compressor at the moment of closing the compressor, the refrigerant will combine with the lubricating oil inside the compressor, after a long time of work, it will cause the compressor to work with a large load, which is easy to cause damage to the scroll in the compressor, and reduces the service life of the compressor, so it is particularly important to further optimize the scroll refrigeration compressor.

[0038] The flow stopping mechanism comprises a mounting disc 7 fixedly installed on the inner wall of the exhaust pipe 6, an elastic pad 8 fixedly installed on the bottom wall of the mounting disc 7, a disc 9 fixedly installed on the bottom wall of the elastic pad 8, a communication groove formed on the mounting disc 7, a communication pipe 10 fixedly installed on the bottom wall of the disc 9 in sliding cooperation with the communication groove, communication ports 11 uniformly formed on the communication pipe 10 and communicating with the exhaust pipe 6, and a sealing disc 12 slidably installed in the exhaust pipe 6, and exhaust ports 13 symmetrically formed on the sealing disc 12.

[0039] The top wall of the mounting disc 7 is symmetrically fixed with a plug rod 14 matched with the exhaust port 13, the plug rod 14 is provided with an annular groove, the top wall and the bottom wall of the annular groove are jointly fixed with an elastic film 15, the mounting disc 7 is provided with a cavity, the cavity is slidably provided with a sealing plate 16, the top wall of the sealing plate 16 is fixed with a push rod 17 extending to the outside, and the side wall of the cavity is inserted with a first air pipe 18 communicated with the annular groove.

[0040] The horizontal rod 19 is fixedly arranged in the exhaust pipe 6, the bottom wall of the horizontal rod 19 and the sealing disc 12 are jointly fixed with a reset air bag 20, the bottom wall of the sealing plate 16 and the cavity are jointly fixed with a spring 21, the bottom wall of the sealing plate 16 is fixed with a baffle 22, and the baffle 22 is provided with a communication hole 23 matched with the first air pipe 18.

[0041] In the initial state, the elastic pad 8 is in the contracted state, and at this time, the bottom wall of the sealing disc 12 is attached to the mounting disc 7, in use, the motor 3 is powered on first, then the motor 3 drives the eccentric shaft 4 to rotate through the output end, and drives the dynamic rotor 5 to perform eccentric motion in the process of rotating the eccentric shaft 4, then the high-pressure refrigerant is formed after the refrigerant is operated by the dynamic rotor 5 and the stator 2, then the high-pressure refrigerant flows upward through the exhaust pipe 6, in the process of the high-pressure refrigerant passing through the exhaust pipe 6, the pressure below the disc 9 is increased, then the communication pipe 10 drives the disc 9 to move upward under the action of the pressure, at this time, the elastic pad 8 is compressed, and at the same time, the sealing disc 12 is upwardly pushed and moved upward in the process of the communication pipe 10 moving upward, and since there is a gap between the exhaust port 13 and the plug rod 14, when the communication hole 11 and the communication groove are separated, the refrigerant flows into the exhaust pipe 6 above the sealing disc 12 through the gap between the communication pipe 10, the communication hole 11, the exhaust port 13 and the plug rod 14, then when the compressor stops working, that is, when the motor 3 stops working, the dynamic rotor 5 stops working and no longer generates high-pressure refrigerant, that is, the high pressure below the disc 9 disappears, then the elastic pad 8 is contracted and drives the communication pipe 10 to move downward through the disc 9, in the process of the communication pipe 10 moving downward, the communication hole 11 is gradually separated from the exhaust pipe 6, and at the same time, the sealing disc 12 moves downward and gradually resets under the action of gravity, thereby effectively preventing the refrigerant from flowing back to the inside of the compressor and combining with the lubricating oil, causing damage to the compressor, and prolonging the service life of the compressor.

[0042] In the process of moving the sealing disc 12 upward, the reset air bag 20 is compressed and has a tendency to recover, then in the process of moving the communication pipe 10 downward, the reset air bag 20 is gradually separated from the sealing disc 12, at this time, the reset air bag 20 is stretched and drives the sealing disc 12 to move downward quickly, so that the exhaust port 13 is attached to the mounting disc 7, further improving the flow stopping effect, and improving the flow stopping effect.

[0043] In the process of the sealing disc 12 moving downward, the sealing disc 12 gradually contacts the push rod 17 and drives the push rod 17 to move downward, in the process of the push rod 17 moving downward, the push rod 17 drives the sealing plate 16 to move downward, and the pressure in the space below the sealing plate 16 in the cavity is increased, at this time, the spring 21 is compressed, then in the process of the sealing plate 16 moving downward, the sealing plate 16 drives the baffle 22 to move downward, then in the process of the baffle 22 moving downward, the baffle 22 gradually contacts the first air pipe 18 and seals the first air pipe 18, then when the bottom wall of the sealing disc 12 is attached to the mounting disc 7, the baffle 22 drives the communication hole 23 to contact the first air pipe 18, and at this time, the elastic membrane 15 is located in the communication groove, then under the action of the pressure, the airflow in the cavity flows to the annular groove through the first air pipe 18, then under the action of the airflow, the elastic membrane 15 expands and is attached to the inner wall of the exhaust port 13, at this time, the expanded elastic membrane 15 fills the exhaust port 13 and seals the exhaust port 13, thereby effectively preventing the refrigerant from flowing back to the inside of the device through the exhaust port 13, the gap between the sealing disc 12 and the mounting disc 7, the gap between the communication port 11 and the communication groove, and the communication pipe 10, thereby improving the flow stopping effect.

[0044] When the sealing disc 12 moves upward and gradually separates from the push rod 17, the spring 21 is stretched and drives the sealing plate 16 to move upward, in the process of the sealing plate 16 moving upward, the sealing plate 16 drives the baffle 22 to move upward, and the first air pipe 18 is separated from the communication hole 23, then when the spring 21 is reset, the sealing plate 16 drives the baffle 22 to separate from the first air pipe 18, at this time, the elastic membrane 15 is contracted and drives the gas in the annular groove to flow to the cavity through the first air pipe 18, thereby playing a role in preparing for work again.

[0045] As shown in Figure 3 , Figure 6 , Figure 7 , the side wall of the shell 1 is fixedly provided with a placing block 24, and the placing block 24 is provided with a placing groove 25 for storing the drying agent.

[0046] A sliding groove is formed in the bottom wall of the placing block 24, and a vertical plate 26 matched with the placing groove 25 is slidably installed in the sliding groove. A gas cylinder 27 is fixedly installed on the top wall of the placing block 24, and a piston plate 28 is slidably installed in the gas cylinder 27. A first linkage rod 29 fixedly connected with the vertical plate 26 is fixedly installed on the bottom wall of the piston plate 28. A second air pipe 30 communicated with the gas cylinder 27 is inserted in the reset air bag 20.

[0047] A filter screen 31 is embedded in the placing groove 25, and a partition plate 32 matched with the filter screen 31 is embedded in the placing groove 25. A rotating rod 33 matched with the filter screen 31 is rotatably installed on the side wall of the shell 1. A brush plate 34 is fixedly installed on the rotating rod 33. Brush hairs 35 matched with the filter screen 31 are uniformly fixedly installed on the side wall of the brush plate 34.

[0048] The rotating rod 33 is provided with a linkage groove, the side wall of the shell 1 is fixedly provided with a mounting rod 36, the mounting rod 36 is provided with a rectangular groove, the rectangular groove is slidably provided with a rectangular block 37, the side wall of the rectangular block 37 is fixedly provided with a second linkage rod 38 extending into the linkage groove, the communication groove is provided with a rotating groove 43, and the second linkage rod 38 is fixedly provided with a driving block 39 matched with the rotating groove 43 at the end away from the rectangular block 37.

[0049] The elastic pad 8 is provided with an air cavity, the air cavity is provided with a third air pipe 40 communicated with the rectangular groove, and the rotating rod 33 is uniformly fixedly provided with a stirring rod 41.

[0050] By adopting the above technical scheme, the eccentric shaft 4 drives the dynamic rotor 5 to make eccentric motion in the process of rotation, then the external airflow enters the compressor through the filter screen 31, the placing groove 25 and the air inlet, when the external air is relatively humid, the drying agent in the placing groove 25 can dry the entering airflow, thereby effectively preventing the moisture from entering the compressor to cause rust in the compressor, and the filter screen 31 can block the dust in the airflow, thereby effectively preventing the dust from entering the compressor, shortening the service life of the compressor and prolonging the service life of the compressor.

[0051] When the reset air bag 20 is compressed, the gas in the reset air bag 20 flows to the air cylinder 27 through the second air pipe 30, then the piston plate 28 drives the first linkage rod 29 to move under the action of the airflow, since the vertical plate 26 is made of light stainless steel material, the vertical plate 26 has sufficient strength, light gravity and good corrosion resistance by making the vertical plate 26 of light stainless steel material, then the vertical plate 26 is driven to move downward in the process of movement of the first linkage rod 29, and gradually separates from the filter screen 31 in the process of downward movement of the vertical plate 26, that is, the airflow can normally enter the compressor through the drying agent at this time, then when the compressor stops working, the reset air bag 20 is stretched and inhales the air from the air cylinder 27 through the second air pipe 30, then the piston plate 28 drives the first linkage rod 29 to move upward as the airflow is sucked to the reset air bag 20, then the vertical plate 26 is driven to move upward and abut with the filter screen 31 in the process of upward movement of the first linkage rod 29, thereby effectively preventing the moisture in the external air from adhering to the drying agent when the compressor stops working, causing the drying agent to be quickly saturated and affecting the drying effect of the airflow, and preventing the dust floating in the external air from adhering to the surface of the filter screen 31 to affect the normal passing of the airflow through the filter screen 31.

[0052] During the compression of the elastic pad 8, the airflow in the air chamber flows through the third air pipe 40 into the mounting rod 36. Then, under the action of the airflow, the rectangular block 37 drives the drive block 39 to move through the second linkage rod 38. During the movement of the drive block 39, the rotating rod 33 is driven to rotate through the rotating groove 43. Similarly, when the elastic pad 8 is extended, the air chamber draws air from the mounting rod 36 through the third air pipe 40. Then, under the action of the airflow, the rectangular block 37 drives the rotating rod 33 to rotate through the second linkage rod 38, the drive block 39, and the rotating groove 43. During the rotation of the rotating rod 33, the rotating rod 33 drives the stirring rod 41 to rotate and stir the desiccant in the placement groove 25. This loosens the desiccant, increases the contact area between the moisture in the airflow and the desiccant, and effectively prevents partially saturated desiccant from accumulating together, affecting the desiccant's adsorption effect on the moisture in the airflow, thus improving the airflow drying effect.

[0053] During the rotation of the rotating rod 33, the brush plate 34 is driven to rotate, and then the brush bristles 35 are driven to rotate, cleaning the dirt on the surface of the filter screen 31. This effectively prevents the filter screen 31 from becoming clogged and affecting the normal airflow into the compressor, thus ensuring the normal operation of the compressor.

[0054] like Figure 7 As shown, the surface of the drive block 39 is a smooth mirror surface.

[0055] By adopting the above technical solution, the driving block 39 will rub against the rotating rod 33 during the process of driving the rotating rod 33 to rotate through the rotating groove 43. By making the surface of the driving block 39 a smooth mirror, the friction between the friction block and the rotating groove 43 can be reduced, thereby ensuring that the driving block 39 can normally drive the rotating rod 33 to rotate through the rotating groove 43, and also reducing the degree of wear between the driving block 39 and the rotating groove 43, thus ensuring that the driving block 39 can normally drive the rotating rod 33 to rotate through the rotating groove 43.

[0056] like Figure 3 As shown, a limiting rod 42 that slides with the sealing disc 12 is fixedly installed on the horizontal rod 19.

[0057] By adopting the above technical solution, the sealing disc 12 can be limited by setting the limiting rod 42, thereby effectively preventing the sealing disc 12 from tilting and getting stuck during the movement, thus ensuring the normal movement of the sealing disc 12.

[0058] The use method is as follows: when the compressor stops working, the motor 3 stops working, the dynamic rotor 5 stops working and no longer generates high-pressure refrigerant, the high pressure under the disc 9 disappears, then the elastic pad 8 is contracted and drives the communicating pipe 10 to move downwards through the disc 9, the communicating port 11 is gradually separated from the exhaust pipe 6 in the process that the communicating pipe 10 moves downwards, the sealing disc 12 is gradually reset and moves downwards under the action of gravity, thereby effectively preventing the refrigerant from flowing back to the inside of the compressor and combining with the lubricating oil; the sealing disc 12 gradually contacts the push rod 17 and drives the push rod 17 to move downwards in the process that the sealing disc 12 moves downwards, the communicating hole 23 is driven to contact the first air pipe 18 through the baffle 22 in the process that the push rod 17 moves downwards, then the airflow in the cavity flows to the annular groove through the first air pipe 18 under the action of pressure, then the elastic film 15 expands and is attached to the exhaust port 13 under the action of the airflow; when the compressor stops working, the reset air bag 20 is stretched and inhales air from the air cylinder 27 through the second air pipe 30, then the piston plate 28 drives the vertical plate 26 to move upwards and be attached to the filter screen 31 through the first connecting rod 29, thereby effectively preventing the moisture in the external air from adhering to the drying agent when the compressor stops working, so that the drying agent is quickly saturated and the drying effect of the airflow is affected; the airflow in the air cavity flows to the mounting rod 36 through the third air pipe 40 in the process that the elastic pad 8 is compressed, then the rectangular block 37 is driven to rotate through the second connecting rod 38, the driving block 39 and the rotating groove 43 under the action of the airflow, then the stirring rod 41 is driven to rotate and stirs the drying agent in the placing groove 25 in the process that the rotating rod 33 rotates, thereby the drying agent can be loosened, the contact area between the moisture in the airflow and the drying agent is increased, and thereby the drying agent that is partially saturated is prevented from being accumulated together and affecting the adsorption effect on the moisture in the airflow.

[0059] The above merely describes the preferred embodiments of the present application; however, the protection scope of the present application is not limited to this. Any person skilled in the art can make equivalent replacements or changes to the technical scheme of the present application and the improvement concept thereof within the technical scope disclosed by the present application, which should be covered by the protection scope of the present application.
