[0026] Working principle: When in use, it will be installed at the outlet of the equipment oil cooler. When working, the liquid can enter the tank body 1 through the water inlet pipe 103 and the connecting pipe 102. Through the two L-shaped water outlet heads 104 and the spiral guide plate 105, the liquid can form a vortex and perform cyclone separation, which can extend the liquid residence time and promote oil-water stratification. At this time, the water droplets with higher density settle downward along the cylinder wall of the tank body 1 under the action of centrifugal force, and then enter the static area at the bottom of the tank body 1. When the static area is filled, the small particles of water suspended in the liquid after cyclonic separation, after being blocked by the wavy three-dimensional mesh plate 5 and the magnetic filter plate 6, under the action of the wavy three-dimensional mesh plate 5, the wave structure can increase the contact area, form a surface tension difference, accelerate the oil droplets to gather and float, and under the action of the magnetic filter plate 6, the magnetic plate can adsorb gold The impurities are filtered at multiple stages and gathered into large particles of water again. These large particles of water will settle down along the wavy three-dimensional mesh plate 5 and the drainage tube 4. Finally, the lubricating oil containing a small amount of water will be filtered again through the filter tube 3. The lubricating oil after dehydration is discharged from the outlet pipe 201. All the water in the above liquid is settled and collected in the static area at the bottom of the tank body 1. After standing, it is finally discharged from the drain pipe 701. By setting an infrared oil sensor 702, the oil content in the drainage water can be detected. Then, in conjunction with the electric control valve 703, the separation effect can be monitored in real time, and the valve can be triggered to close to prevent oil leakage. When the filter tube 3 is blocked, the L-shaped overflow pipe 1023 located on the side of the tank body 1 can ensure the oil supply to the pipeline, avoid accidents caused by oil outages, and ensure that there is a smooth oil path in the pipeline under any circumstances. When it is necessary to replace the filter cartridge 3, the wavy three-dimensional mesh plate 5 and the magnetic filter plate 6, people rotate the fastening bolts 1020 to disengage the extrusion block 1021 from the limit frame 202. After the disengagement is completed, people can remove the top cover 2 from the top of the tank body 1. After the disassembly is completed, people can remove the drainage cartridge 4 and the filter cartridge 3 from the top of the T-shaped placement table 101, so that people can clean or replace the filter components. After cleaning or replacing them, people rotate multiple fastening bolts 1020 to push the extrusion block 1021 to lock it. The top cover 2 is inserted into the limiting frame 202 and is installed on the top of the tank body 1 by tightening the bolts 1020. The top of the T-shaped placing platform 101 is fixedly connected with a convex sealing strip 1022, and the bottom of the top cover 2 is fixedly connected with a concave sealing strip 203. The top of the convex sealing strip 1022 is clamped on the bottom of the concave sealing strip 203. Then, under the action of the convex sealing strip 1022 and the concave sealing strip 203, the top cover 2 and the top of the tank body 1 are in close contact, which can prevent liquid leakage and enhance the airtightness of the top cover 2 and the tank body 1. The device realizes an efficient and continuous oil-water separation process through its unique design and technical features, ensuring the purity of the fluid and the stable operation of the system. First, through the cooperation of the wavy three-dimensional mesh plate 5 and the magnetic filter plate 6, it can effectively block solid particles, suspended matter and other impurities in the fluid and prevent them from entering the system, thereby protecting the normal operation of downstream equipment and processes. Secondly, the oil-water separation function is the core of the filter. Through the hydrophobic and oleophilic coating on the surface of the wavy three-dimensional mesh plate 5, and the cooperation of the drain pipe 701 and the electric control valve 703 of the bottom cover 7, the oil-water mixture is effectively separated. The selection and design of the coating make it easier for the oil to adhere to the mesh plate, while the water passes through the mesh plate. The plate is discharged, thereby achieving an efficient oil-water separation effect. The real-time monitoring function can also monitor and provide real-time feedback on key parameters such as oil concentration and flow rate during the separation process through the infrared oil sensor 702 and the electric control valve 703, providing accurate data support for operators, facilitating timely adjustment of operating parameters, ensuring separation effect and stability of system operation. Finally, by setting an elastic telescopic rod 1024, a positioning block 1025 and a positioning hole 1017, an elastic locking system can be formed, and then the extrusion block 1021 is driven to be stuck in the limit frame 202 by tightening the bolt 1020, which can complete the rapid sealing and fixation of the top cover 2, thereby facilitating people to clean or replace the filter component.
