Detailed implementation mode
[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.
[0020] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.
[0021] Embodiment 1, as Figure 1 shown, an oil mist fan smoke exhaust pipeline for an oil station includes an oil station 1. The oil station 1 serves as a storage and supply station for lubricating oil, responsible for providing lubricating oil to ensure the stable supply of lubricating oil. Through a closed design, it reduces the problems of oil fume overflow and oil leakage. The oil station 1 is connected to an oil mist filter element 3 through an oil filter pipeline 2. The oil mist filter element 3 is used to filter oil mist, reduce the emission of oil mist particles, protect the environment, and at the same time ensure that the oil mist will not cause pollution and wear to other components.
[0022] The oil filter pipeline 2 connects the oil station 1 and the oil mist filter element 3, playing the role of transporting lubricating oil. The bottom of the oil mist filter element 3 is connected to the oil filter pipeline 2 through a return pipe 4. The return pipe 4 returns the unfiltered oil mist to form oil liquid and then returns it to the oil filter pipeline 2, avoiding waste of resources, improving the utilization efficiency of lubricating oil, reducing waste and consumption of lubricating oil, and thus reducing the operating cost.
[0023] A smoke exhaust pipeline 7 is provided on one side of the oil mist filter element 3. A check valve 10 is provided at the end of the smoke exhaust pipeline 7. The check valve 10 prevents the gas or oil fume in the smoke exhaust pipeline 7 from flowing back, avoiding the phenomenon of reverse suction of air, and ensuring normal negative pressure and smoke exhaust effect. The smoke exhaust pipeline 7 is connected to a venting port 11. The smoke exhaust pipeline 7 is used to guide the oil mist or oil fume to the venting port 11 for discharge. The venting port 11 is connected to the atmosphere, and can safely discharge the oil fume, avoiding internal accumulation.
[0024] The exhaust pipe 7 leads out a return pipe 12 which is connected to the oil filtering pipe 2. The return pipe 12 recirculates part of the oil mist in the exhaust pipe 7 after condensation back to the oil filtering pipe 2 for reuse, reducing emissions to the external environment and saving resources.
[0025] One side of the top of the oil mist filter element 3 leads out a smoking pipe 14 which is connected to the oil mist fan 15. The oil mist fan 15 is connected to the exhaust pipe 7 through a connecting pipe 16. The oil mist fan 15 extracts the oil mist from the filter element and transports it to the exhaust pipe 7 through the smoking pipe 14, timely discharging the oil mist in the system, preventing the accumulation of oil mist, and reducing the risks of oil leakage and fire.
[0026] The following specifically describes the specific designs of the above key components:
[0027] A reflux valve 5 and a viewing window 6 are provided on the reflux pipe 4. The reflux valve 5 controls the reflux direction of the oil liquid in the reflux pipe 4 to prevent backflow. The viewing window 6 provides a window for the operator to observe the reflux situation, facilitating real-time monitoring of the system operation status, enabling intuitive inspection of the status of the reflux oil liquid, timely discovery of abnormal situations, and convenient maintenance and management.
[0028] A first exhaust valve 8 and a second exhaust valve 9 are provided on the exhaust pipe 7. The first exhaust valve 8 is arranged on the front side of the position where the return pipe 12 leads out from the exhaust pipe 7, and the second exhaust valve 9 is arranged on the rear side of the position where the connecting pipe 16 leads out from the exhaust pipe 7. The first exhaust valve 8 and the second exhaust valve 9 are used to control the opening and closing at different positions in the exhaust pipe 7, realizing the guiding effect of oil fume between different pipes, enabling more precise adjustment of oil fume emissions, ensuring the exhaust effect under different working conditions, and maintaining negative pressure balance.
[0029] A check valve 13 is provided on the return pipe 12. The check valve 13 ensures that the oil fume gas in the return pipe 12 can only flow in one direction, preventing backflow, avoiding the backflow of oil fume into the system, preventing damage to the equipment, and improving the operation safety of the system.
[0030] The oil station 1 is connected to the second oil mist filter element 18 through a second oil filtering pipe 17. The bottom of the second oil mist filter element 18 is connected to the second oil filtering pipe 17 through a second reflux pipe 19. One side of the second oil mist filter element 18 is provided with a second exhaust pipe 22. A second check valve 23 is arranged at the end of the second exhaust pipe 22. The second exhaust pipe 22 is connected to the vent port 11. A second return pipe 24 is led out from the second exhaust pipe 22 and connected to the second oil filtering pipe 17. One side of the top of the second oil mist filter element 18 leads out a second smoking pipe 26 which is connected to the second oil mist fan 27. The second oil mist fan 27 is connected to the second exhaust pipe 22 through a second connecting pipe 28.
[0031] The second oil filter pipe 17 connects the oil station 1 and the second oil mist filter 18 to transport lubricating oil and provide a second set of channels for filtering oil mist to ensure the cleanliness of the lubricating oil, further improve the redundancy of the system, and prevent the failure of a single pipeline from affecting the overall operation. The second oil mist filter 18 is used to filter the oil mist to prevent particles from entering the external pipeline or leaking. The second return pipe 19 returns the underutilized oil mist or lubricating oil to the second oil filter pipe 17 to avoid waste.
[0032] The second smoke exhaust pipe 22 is connected to the second oil mist filter 18, and discharges the oil smoke and gas to the vent 11 to prevent the accumulation or leakage of oil smoke. The second check valve 23 prevents the oil smoke or gas in the second smoke exhaust pipe 22 from flowing back, ensuring the consistent flow direction and avoiding the problem of backdraft. The second return pipe 24 returns part of the exhaust gas or oil mist to the second oil filter pipe 17 for recycling. The second smoke extraction pipe 26 extracts the oil mist from the second oil mist filter 18, cooperates with the second oil mist fan 27 to remove the oil smoke in time, and the second connecting pipe 28 connects the second smoke extraction pipe 26 with the second smoke exhaust pipe 22 to ensure the smooth discharge of oil smoke.
[0033] The second return pipe 19 is provided with a second return valve 20 and a second viewing window 21. The second return valve 20 controls the opening and closing of the second return pipe 19 and monitors the oil return condition through the viewing window 6.
[0034] The second return pipe 24 is provided with a second one-way valve 25 , and the second one-way valve 25 allows the oil fume gas in the second return pipe 24 to flow in one direction only, thereby preventing backflow.
