[0020] Example

[0021] like Figure 1 、 2As shown, in this embodiment, a turbine oil filtration system is mainly disclosed, including an oil collecting channel 1, a first filter 2 is provided in the oil collecting channel 1, an oil pump is provided inside the first filter 2, the oil pump is connected to a second filter 3 through a pipeline, an oil overflow pipe 4 connected to the oil collecting channel 1 is provided on the upper part of the second filter 3, and an oil outlet pipe 5 and a sewage pipe 6 connected to the oil collecting channel 1 are provided on the lower part of the second filter 3; specifically, the oil collecting channel 1 is dug on the foundation to collect turbine oil used in the oil circulation test, the oil is subjected to gravity in the oil collecting channel 1, so that impurities in the oil are gradually precipitated, and then discharged through the oil pump By suction, the oil is initially filtered by the first filter 2 and then transported to the second filter 3 for re-filtration. The filtered oil is collected to the subsequent clean oil area through the oil outlet pipe 5, and the deposited impurities are filtered in the second filter 3. After the oil in the oil collecting channel 1 is collected and filtered, it is discharged into the oil collecting channel 1 through the drain pipe 6; the filtration system is set up through the oil collecting channel 1, the first filter 2 and the second filter 3. After preliminary sedimentation, multi-stage filtration is performed to effectively remove impurities in the oil, thereby ensuring the filtration quality and cleanliness of the oil, effectively avoiding filter clogging, and extending the service life of the equipment.

[0022] Furthermore, in specific implementation, the above-mentioned second filter 3 provided in the embodiment of the present utility model is arranged at a position higher than the oil collecting channel 1; specifically, the first filter 2 is arranged in the oil collecting channel 1, and the second filter 3 can be installed on the foundation, that is, the second filter 3 is positioned higher than the first filter 2, forming a height difference, and the oil in the oil collecting channel 1 is lifted and transported to the second filter 3 by suction by the oil pump, so that in the second filter 3, whether it is oil that needs to be refluxed through the overflow pipe or deposited impurities that need to be discharged, they do not need to rely on the energy consumption of the pump, and can flow smoothly to the oil collecting channel 1 under the action of gravity, thereby improving the overall efficiency of the system.

[0023] Furthermore, in a specific implementation, the bottom surface of the above-mentioned oil collecting channel 1 provided in the embodiment of the utility model is arranged inclined along the length direction, and the first filter 2 is arranged at the lower part of the oil collecting channel 1; the effect of gravity is fully utilized to make it easier for turbine oil, impurities and sediment to gather at the lower part of the oil collecting channel 1, thereby ensuring the effectiveness of the filtration system, and also conveniently collecting and processing the dirt at the bottom, simplifying the maintenance and cleaning process.

[0024] Furthermore, in specific implementation, Figure 3As shown, the above-mentioned first filter 2 provided in the embodiment of the present invention includes a first sieve drum 21, and a sieve plate 22 is connected to the bottom of the first sieve drum 21; specifically, the first sieve drum 21 is a hollow cylindrical structure, and its bottom is detachably connected to the sieve plate 22 by bolts. A number of filter holes are provided on the first sieve drum 21 and the sieve plate 22. The top of the first sieve drum 21 can be connected to a top cover for blocking external pollutants from entering its interior. The oil is coarsely filtered through the first sieve drum 21 and enters the first sieve drum 21 from the outside, blocking impurities of larger particles from being retained in the oil collecting channel 1, protecting subsequent filtering equipment, reducing the burden on subsequent filters, reducing the risk of clogging, facilitating later maintenance and cleaning, and improving the maintainability of the system.

[0025] Furthermore, in specific implementation, Figure 4 As shown, the above-mentioned second filter 3 provided in the embodiment of the present invention includes a sealed container 31, and a second sieve drum 32 is installed in the sealed container 31; specifically, the second sieve drum 32 is a cylindrical structure with an open top, a filter wall and a bottom, and is clamped in the sealed container 31. There is a space between the outer wall of the second sieve drum 32 and the inner wall of the sealed container 31, which can accommodate the filtered oil, and the space is directly connected to the oil outlet pipe 5; after the oil enters the sealed container 31, it flows to the inside of the second sieve drum 32, and after being filtered by the second sieve drum 32, it flows to the above-mentioned space and is transported to the subsequent oil purification area through the inlet and outlet oil pipes 5; it should be noted that the first filter 2 and the second sieve drum 32 can both adopt a multi-layer nested structure to achieve multi-stage filtration of a single filter and improve the filtering effect.

[0026] Furthermore, in specific implementation, Figure 1 As shown, the above-mentioned oil collecting channel 1 provided in the embodiment of the present invention is connected to a drain valve 11 through a pipeline; after the oil in the oil collecting channel 1 is collected and filtered, and the impurities in the second filter 3 are discharged through the drain pipe 6, flushing liquid is introduced into the oil collecting channel 1 for flushing, and the drain valve 11 is opened for sewage treatment.

[0027] Furthermore, in specific implementation, Figure 1 、 2 As shown in Figures 4 and 5, the oil overflow pipe 4 provided in the embodiment of the present invention is equipped with a high-pressure valve 7; when the internal pressure difference of the second filter 3 reaches a set value, the high-pressure valve 7 automatically opens, and the pressure is automatically released through the oil overflow pipe 4, so that part of the oil flows back to the oil collecting channel 1, thereby ensuring the quality of oil filtration and avoiding damage to the second filter 3 due to excessive pressure.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
