[0031] The present invention will be further described below by way of embodiments, but the present invention is not limited to the scope of the described embodiments accordingly.

[0033] The support perforated plate 304 is used to fix the oil-gas separation component, and the support perforated plate 304 is made of punched metal plate, allowing air flow to pass through.

[0034] In specific implementation, the whole device adopts a modular design, making maintenance and replacement more convenient and fast, reducing the maintenance cost; and multiple modules are stacked to achieve multi-stage oil-gas separation, improving the separation efficiency, and maintaining performance even when dealing with high-flow compressed air.

[0036] The outer frame 301 serves as the external frame of the oil-gas separation module 3, providing an installation space for the oil-gas separation component inside it. Oil and gas pass through the outer frame 301 and are separated by the oil-gas separation component.

[0037] Specifically, the oil-gas separation component is made of glass fiber, replacing traditional metal parts, not only reducing the cost, but also improving the air permeability and separation efficiency, and at the same time reducing the impact on the environment.

[0038] The condensation layer 302 and the splash-proof layer 303 are fixed on the support perforated plate 304 by fastening screws or buckles to ensure that they will not be displaced under the action of air flow; the support perforated plate 304 is fixed inside the outer frame 301 by welding or bolt connection to ensure stable installation.

[0039] Seal members are provided at the installation locations of the coagulation layer 302 and the support orifice plate 304, as well as at the installation locations of the splash-proof layer 303 and the support orifice plate 304, to ensure the sealing of the installation locations and prevent oil and gas leakage.

[0040] As Figure 3 shown, as a specific technical solution, an opening located above the coagulation layer 302 and the splash-proof layer 303 is provided at the top of the outer frame 301, and a cover plate 6 is installed at the opening at the top of the outer frame 301.

[0041] Among them, the cover plate 6 is installed at the opening at the top of the outer frame 301.

Through the opening, maintenance personnel can enter the outer frame 301 to perform maintenance and cleaning on the interior.

[0042] As Figure 7 shown, the detachable mechanism includes a first connecting ring 4 and a second connecting ring 5. A slot 401 is provided on one side of the first connecting ring 4. A plugging component 10 is provided on one side of the second connecting ring 5. The plugging component 10 includes a plug 1001 fixedly installed on one side of the second connecting ring 5. The plug 1001 is inserted into the slot 401. A plurality of locking holes 403 are provided at the top and bottom of the slot 401. A plurality of locking columns 1004 are movably installed at the top and bottom of the plug 1001, and the locking columns 1004 are inserted into the locking holes 403. The locking columns 1004 are connected to a pneumatic driving part.

[0043] The pneumatic driving part includes an air injection valve 1009 and an air passage 1008 provided in the second connecting ring 5. The air passage 1008 is communicated with one end of the air injection valve 1009, and the air injection valve 1009 is fixedly installed on the side wall of the second connecting ring 5. A sliding cavity 1002 and a communication groove 1007 are provided inside the plug 1001. The air passage 1008 is communicated with the sliding cavity 1002 through the communication groove 1007. The sliding cavity 1002 is cooperatively connected with a piston 1005. The piston 1005 is fixedly sleeved with the end of the locking column 1004. Guide holes 1003 communicated with the sliding cavity 1002 are provided at the top and bottom of the plug 1001. The locking column 1004 is slidably sleeved with the guide hole 1003. The end of the locking column 1004 is elastically connected to the wall of the sliding cavity 1002 through a second spring 1006.

[0044] An inflatable sealing ring 11 is fixedly installed on the side wall of the second connecting ring 5. An annular embedding groove 402 is provided on the side wall of the first connecting ring 4. The inflatable sealing ring 11 is embedded in the annular embedding groove 402. An interface is provided on the inflatable sealing ring 11, and the interface is communicated with the air passage 1008.

[0045] In the entire oil and gas separation device, the number of oil and gas separation modules 3 can be arbitrarily adjusted according to requirements. The disassembly and assembly between the oil and gas separation modules 3, the disassembly and assembly between the intake end 1 and the oil and gas separation module 3, and the disassembly and assembly between the outlet end 2 and the oil and gas separation module 3 are all realized by operating the quick-disassembly mechanism.

[0046] In specific implementation, the intake end 1 is located at the front side of the entire device, and a first connecting ring 4 is fixedly installed on the side of the intake end 1. The outlet end 2 is located at the rear side of the entire device, and a second connecting ring 5 is fixedly installed on the side of the outlet end 2. A second connecting ring 5 and a first connecting ring 4 are respectively fixedly installed on the front and rear sides of each oil and gas separation module 3.

[0047] The disassembly and assembly of adjacent oil and gas separation modules 3, and the disassembly and assembly of the oil and gas separation module 3 with the intake end 1 and the outlet end 2 are all realized by the disassembly and assembly of the first connecting ring 4 and the second connecting ring 5.

[0048] When the first connecting ring 4 and the second connecting ring 5 are installed, the injection valve 1009 is in the open state, and the locking column 1004 is received into the guide hole 1003 and the sliding cavity 1002, so that the first connecting ring 4 and the second connecting ring 5 are close to each other and fit, and the insertion block 1001 is inserted into the slot 401. The locking column 1004 is aligned with the locking hole 403. Keeping the above state, then connect the external gas injection device to the port of the injection valve 1009. By injecting high-pressure air flow into the injection valve 1009, the air flow enters the sliding cavity 1002 through the air duct 1008 and the communication groove 1007, increasing the air pressure in the sliding cavity 1002. Through the air pressure, the piston 1005 and the locking column 1004 move, and the locking column 1004 is inserted into the locking hole 403, and the second spring 1006 is stretched. At the same time, the air flow in the air duct 1008 enters the inflatable sealing ring 11 to inflate the inflatable sealing ring 11 to make it expand. Finally, close the injection valve 1009 to complete the installation.

[0049] When the first connecting ring 4 and the second connecting ring 5 are disassembled, open the injection valve 1009, exhaust outward through the injection valve 1009, and the gas in the inflatable sealing ring 11 and the sliding cavity 1002 is discharged. The piston 1005 loses the air pressure, and through the elastic force of the second spring 1006, the locking column 1004 is separated from the locking hole 403, and then the insertion block 1001 is pulled out from the slot 401 to complete the disassembly.

[0050] Through the above design, the installation and disassembly are convenient. At the same time, during the installation process, the inflatable sealing ring 11 is automatically inflated, ensuring the sealing performance of the installation.

[0051] Such as Figure 2 、 Figure 4 、 Figure 6 and Figure 8As shown, as a specific technical solution, the shielding mechanism is composed of a plurality of shielding blades 8, and a plurality of the shielding blades 8 are all rotatably installed in the outer frame 301.

[0052] As Figures 8-11 shown, as a specific technical solution, the driving mechanism 9 includes a first protective shell 902; the first protective shell 902 is fixedly installed on the outer wall of the outer frame 301, a plurality of rotating shafts 905 are rotatably installed in the first protective shell 902, and the end of the rotating shaft 905 is fixedly connected to the end of the shielding blade 8. A first gear 904 is fixedly sleeved on each of the plurality of rotating shafts 905, and every two adjacent first gears 904 are meshed and connected. A connecting shaft 907 is fixedly installed in the middle of one of the first gears 904. A second protective shell 903 is fixedly installed on the first protective shell 902. The connecting shaft 907 extends into the second protective shell 903. An installation frame 908 is fixedly installed in the second protective shell 903. The connecting shaft 907 is rotatably connected to the installation frame 908. A second gear 906 is fixedly sleeved on the connecting shaft 907. The second gear 906 is meshed with a rack 909. The end of the rack 909 is fixedly connected to the end of the pressure rod 901. One end of the rack 909 is fixedly installed with a guide seat 911. A guide hole 1003 is formed in the guide seat 911. A first spring 910 and a guide post 912 are fixedly installed on the inner side wall of the second protective shell 903. The guide seat 911 is elastically connected to the inner side wall of the second protective shell 903 through the first spring 910. The guide post 912 is slidably sleeved with the guide hole 1003.

[0053] Through holes are formed in the second protective shell 903, the first connecting ring 4 and the second connecting ring 5, and the pressure rod 901 penetrates through the through holes; when the oil-gas separation module 3 is not installed on the whole device and stored in the warehouse, the pressure rod 901 extends out from the side of the first connecting ring 4 and the second connecting ring 5, as Figure 3 shown, and the shielding mechanisms on both sides of the oil-gas separation module 3 are in a closed state, that is, all the shielding blades 8 of the shielding mechanism form a partition wall, as Figure 3 、 Figure 6 and Figure 8 shown, for shielding and protecting the inside of the outer frame 301 in the uninstalled state to prevent dust and foreign objects from entering.

[0054] The oil-gas separation module 3 is installed on the entire device. The two sides of the oil-gas separation module 3 are connected by a detachable mechanism. The first connecting ring 4 and the second connecting ring 5 are fitted. When the pressure rod 901 is pressed, it moves into the second protective shell 903. The pressure rod 901 drives the rack 909 to move together. Through the meshing transmission between the rack 909 and the second gear 906, the second gear 906 rotates. A first gear 904 is driven to rotate through the transmission shaft. Through the meshing transmission between the first gears 904, all the first gears 904 rotate. Specifically, all the first gears 904 rotate by 90°. The first gear 904 drives the shielding blade 8 to rotate by 90° through the rotating shaft 905. Thus, an inter-groove is formed between every two adjacent shielding blades 8. After installation, the shielding mechanism is automatically opened to ensure the passage of air flow. During the above process, the rack 909 moves, and the guide holes 1003 and the guide posts 912 provide guidance and compress the first spring 910.

[0055] Through the above design, when the oil-gas separation module 3 is stored, it can provide dust protection for the condensation layer 302, the splash-proof layer 303, and the support hole plate 304 inside the outer frame 301. When in use, the oil-gas separation module 3 is installed on the entire device, and the shielding can be automatically cancelled without manual operation.

[0056] As Figures 1-3 shown, as a specific technical solution, each oil-gas separation module 3 respectively includes an oil drainage mechanism 7 that works independently and does not interfere with each other. Each oil drainage mechanism 7 respectively has an oil sump 701, an oil discharge pipe 702, and a one-way oil discharge valve 703. The oil sump 701 is arranged below the condensation layer 302 and the splash-proof layer 303, and the cross-section of the oil sump 701 is triangular. The top end of the oil discharge pipe 702 is fixedly communicated with the oil sump 701, and the bottom end of the oil discharge pipe 702 is connected with the one-way oil discharge valve 703. A liquid level sensor is arranged in the oil discharge pipe 702. When the oil in the oil sump 701 of one oil drainage mechanism 7 is first stored in the oil discharge pipe 702 and then blocked by a one-way oil discharge valve 703, when the one-way oil discharge valve 703 is open, all the one-way oil discharge valves 703 in other oil drainage mechanisms 7 are in the closed state. When the one-way oil discharge valve 703 is in the open state, only 80% - 90% of the stored oil volume is discharged to prevent the compressed air in the oil-gas separation module 3 from entering the one-way oil discharge valve 703 through the oil discharge pipe 702.

[0057] The oil separated by the oil-gas separation component is collected and received through the oil collecting tank 701 of the oil discharging mechanism 7, and the collected oil enters the oil discharge pipe 702 for storage. The liquid level sensor senses in real time to judge the liquid level condition of the collected oil. After reaching the set maximum liquid level amount, the one-way oil discharge valve 703 is opened to discharge 80% - 90% of the stored oil amount, and then the one-way oil discharge valve 703 is closed; and during the oil discharge of a single oil-gas separation module 3, the oil discharging mechanisms 7 in other oil-gas separation modules 3 are closed and do not discharge oil.

[0058] Both the liquid level sensor and the one-way oil discharge valve 703 are electrically connected to an external controller or control system for the above control.

[0059] The cross-section of the oil collecting tank 701 is triangular, and its bottom is designed as an inclined plane to facilitate the flow of oil droplets to the oil discharge pipe 702 under the action of gravity.

The protection scope of the present invention is defined by the appended claims.
