Description

Technical Field

[0001] This application relates to the technical field of gas-liquid separation, and more specifically, to a gas-liquid separation device dedicated to a refrigeration compressor. Background Art

[0002] A gas-liquid separation device is a separation device that uses the principles of centrifugal separation and wire mesh filtration to achieve liquid removal. It mainly separates gas and liquid based on their different densities. Under the action of inertial gravity and centrifugal force, the gas rises and the liquid drops. When used with a refrigeration compressor, the gas-liquid separation device can prevent liquid refrigerant from entering the interior of the refrigeration compressor, and it is an essential device in the use of refrigeration compressors.

[0003] However, most of the existing gas-liquid separation devices dedicated to refrigeration compressors on the market currently only use wire mesh filtration, resulting in some small liquid droplets still existing in the filtered gas, thereby greatly reducing the gas-liquid separation effect of the device. Utility Model Content

[0004] To solve the above problems, this application provides a gas-liquid separation device dedicated to a refrigeration compressor.

[0005] The gas-liquid separation device dedicated to a refrigeration compressor provided by this application adopts the following technical solutions:

[0012] Furthermore, a limiting rod is fixedly connected to the inner wall of the tank body, and the limiting rod is slidably sleeved with the pressing block.

[0013] Through the above technical solution, the limiting rod can play a role in limiting the pressing block, so that it can only move horizontally.

[0014] Furthermore, one end of the steel wire rope is fixedly connected to one side of the pressing block, and the other end of the steel wire rope is fixedly connected to the liquid storage box.

[0015] Through the above technical solution, after the liquid storage box stores the liquid, it will move downward by gravity, and then drive one end of the steel wire rope to move downward, and then drive the other end of the steel wire rope to wind on the outer wall of the winding rod.

[0016] Furthermore, the outer wall of the liquid storage box is slidably connected to the inner wall of the tank body, the liquid outlet pipe is slidably sleeved with the liquid storage box, and a valve is arranged on the outer wall of the liquid outlet pipe.

[0030] The following will further describe this application in detail in conjunction with the attached Figures 1-4 drawings.

[0031] An embodiment of this application discloses a special gas-liquid separation device for a refrigeration compressor. Please refer toFigures 1-4 , including a tank body 1. An air outlet pipe 2 is fixedly connected to the top of the tank body 1. A support plate 5 is fixedly connected to the inner wall of the tank body 1. A channel 6 is opened at the bottom of the support plate 5. A second wire mesh 7 is fixedly connected to the inner wall of the channel 6. A sponge plate 8 is fixedly connected to the inner wall of the channel 6. A first spring 9 is fixedly connected to the inner side wall of the tank body 1. One end of the first spring 9 is fixedly connected to a pressing block 10.

[0032] A support frame 12 is fixedly connected to the top of the support plate 5. A winding rod 13 is rotatably connected to one side of the support frame 12. A steel wire rope 14 is rotatably wound around the outer wall of the winding rod 13. A second spring 18 is fixedly connected to the inner bottom wall of the tank body 1. A liquid storage box 16 is fixedly connected to the top of the second spring 18. A liquid outlet pipe 15 is fixedly connected to the bottom of the tank body 1. After the gas-liquid mixture enters the tank body 1, the liquid will fall into the interior of the liquid storage box 16 by gravity, and the gas will rise. The second wire mesh 7 can isolate the medium particle liquid molecules in the gas. The gas with small particle liquid molecules will pass through the sponge plate 8, and then the small particle liquid molecules in the gas will be adsorbed. Then the remaining gas can exit through the air outlet pipe 2, so that there will be no small liquid droplets in the filtered gas, and thus the separation effect of the device is effectively improved.

[0033] In this embodiment, a first wire mesh 4 is fixedly connected to the inner wall of the tank body 1, and an air inlet pipe 3 is fixedly connected to the outer wall of the tank body 1. The gas-liquid mixture enters the tank body 1 through the air inlet pipe 3. The liquid will fall into the interior of the liquid storage box 16 by gravity, and the gas will rise. The large particle liquid molecules in the gas will be isolated by passing through the first wire mesh 4.

[0034] In this embodiment, the outer wall of the pressing block 10 is slidably connected to the inner wall of the channel 6, and the bottom of the pressing block 10 is slidably connected to the sponge plate 8. The pressing block 10 moves on the sponge plate 8, so as to press the sponge plate 8, and then the water in the sponge plate 8 will be squeezed out.

[0035] In this embodiment, a limiting rod 11 is fixedly connected to the inner wall of the tank body 1, and the limiting rod 11 is slidably sleeved with the pressing block 10. The limiting rod 11 can play a role in limiting the pressing block 10, so that it can only move horizontally.

[0036] In this embodiment, one end of the steel wire rope 14 is fixedly connected to one side of the pressing block 10, and the other end of the steel wire rope 14 is fixedly connected to the liquid storage box 16. After the liquid storage box 16 stores liquid, it will move downward by gravity, and then drive one end of the steel wire rope 14 to move downward, and then drive the other end of the steel wire rope 14 to wind on the outer wall of the winding rod 13.

[0037] In this embodiment, the outer wall of the liquid storage box 16 is slidably connected to the inner wall of the tank body 1, the liquid outlet pipe 15 is slidably sleeved on the liquid storage box 16, and a valve 17 is provided on the outer wall of the liquid outlet pipe 15. By opening the valve 17, the liquid inside the liquid storage box 16 can be taken out.

[0038] The implementation principle of a special gas-liquid separation device for a refrigeration compressor in an embodiment of the present application is as follows: First, the gas-liquid mixture enters the tank body 1 through the intake pipe 3. The liquid will fall into the inside of the liquid storage box 16 by gravity, and the gas will rise. The large particle liquid molecules in the gas will be separated by the first wire mesh 4. Subsequently, the gas will pass through the second wire mesh 7, and the medium particle liquid molecules therein will be separated. The remaining gas with small particle liquid molecules will pass through the sponge plate 8. The sponge plate 8 has good water absorption performance, and thus will adsorb the small particle liquid molecules in the gas. Then the remaining gas can exit through the outlet pipe 2.

[0039] Second, after the inside of the liquid storage box 16 stores liquid, it will move downward by gravity, which will drive one end of the steel rope 14 to move downward. Then it will drive the other end of the steel rope 14 to wind on the outer wall of the winding rod 13, and thus drive the pressing block 10 to move towards the support frame 12. The pressing block 10 moves on the sponge plate 8, pressing the sponge plate 8, and thus squeezing out the water in the sponge plate 8.

[0040] Finally, by opening the valve 17, the liquid inside the liquid storage box 16 can be taken out. As the liquid inside the liquid storage box 16 decreases, it will reset upward by the elastic force of the second spring 18. Then the top of the liquid outlet pipe 15 will be in the liquid, facilitating the extraction of the liquid.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
