Description

Technical Field

[0001] The utility model relates to the field of wind power lubrication, and in particular to a fin structure magnetic core filter. Background Art

[0002] During the normal operation of the gearbox, the main pollutants contained in the oil are metal (iron) particles generated by the friction of the gear tooth surfaces. After the gearbox is running, the particles in the oil continue to adhere to the tooth surfaces with the oil, acting as "abrasives" during the gear meshing process, causing secondary damage to the tooth surfaces, forming a "vicious cycle."

[0003] Metal (iron) particle contaminants enter the oil pool with the oil. When the lubrication system is working, the metal (iron) particle contaminants are sucked into the gear pump, causing damage to the gear pump tooth surface and cavity during the gear meshing process, and even causing "stuck". At the same time, metal (iron) particle contaminants enter the filter (before filtration) with the oil, which may cause the one-way valve and relief valve core to get stuck, resulting in abnormal system pressure.

[0009] During use, when the oil containing metal particles flows from the above-mentioned liquid inlet of the above-mentioned filter cover to the above-mentioned liquid outlet on the above-mentioned filter cartridge, the magnetic force generated by the above-mentioned magnetic filter element can adsorb the metal particles in the oil on the outer surface of the above-mentioned magnetic filter element.

[0019] Optionally, the magnetic poles of adjacent permanent magnet blocks are the same.

[0048] Example

[0049] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 , this embodiment proposes a fin structure magnetic core filter, including a filter cartridge 1;

[0050] A magnetic filter element 2 is provided inside the filter cartridge 1, and the magnetic filter element 2 is distributed along the axis of the filter cartridge 1. A filter cover 3 is provided at the open end of the filter cartridge 1, and an annular sealing ring 4 is provided between the filter cover 3 and the opening of the filter cartridge 1. A plurality of screws 5 are evenly distributed in the circumferential direction of the filter cover 3. The annular sealing ring 4 fits the opening of the filter cartridge 1, and the side of the filter cover 3 close to the annular sealing ring 4 fits the annular sealing ring 4. The filter cover 3 is fixedly connected to the open end of the filter cartridge 1 by a plurality of screws 5;

[0051] A liquid inlet 6 is provided at the outer end of the filter cover 3 , and a liquid outlet 7 is provided at the end of the filter cartridge 1 away from the filter cover 3 . The liquid inlet 6 and the liquid outlet 7 are in communication with the inner cavity of the filter cartridge 1 .

[0052] During use, when the oil containing metal particles flows from the liquid inlet 6 of the filter cover 3 to the liquid outlet 7 on the filter cartridge 1, the magnetic force generated by the magnetic filter element 2 can adsorb the metal particles in the oil on the outer surface of the magnetic filter element 2. In this way, after the oil containing metal particles passes through the magnetic filter element 2, there are no metal particles in the oil coming out of the liquid outlet 7, thereby preventing the oil containing metal particles from entering the gear box and damaging the gears. The annular sealing ring 4 can play a sealing role, so that when the filter cover 3 is connected to the filter cartridge 1 by a number of screws 5, sufficient sealing is ensured to prevent oil leakage.

[0053] The fin-structured magnetic core filter disclosed in this embodiment effectively disturbs the oil and adsorbs metal particles in the oil through the magnetic filter element 2, thereby purifying the metal particles in the oil, so as to facilitate the purification of the oil and avoid damage to the gearbox gears. As a result, the fin-structured magnetic core filter has the beneficial effects of simple structure, stable performance, easy removal of metal particles in the oil, less likely to cause damage to the gear pump tooth surface and cavity, less likely to cause the one-way valve and the overflow valve core to stick, and easy to maintain normal system pressure.

[0054] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The magnetic filter element 2 is a detachable magnetic filter element 8. The detachable magnetic filter element 8 has a fixed shaft 9. The end of the fixed shaft 9 close to the filter cartridge 1 is fixedly connected to the center of the inner bottom surface of the filter cartridge 1. The end of the fixed shaft 9 away from the filter cartridge 1 is provided with a fixed slip ring 10. The axis of the fixed slip ring 10 is fixedly connected to the end of the fixed shaft 9 away from the filter cartridge 1, and the outer wall of the fixed slip ring 10 is in contact with the inner wall of the filter cartridge 1. The setting of the fixed slip ring 10 provides support for the end of the fixed shaft 9 away from the filter cartridge 1, which facilitates the arrangement of the fixed shaft 9 along the axis of the filter cartridge 1.

[0055] A plurality of annular spoilers 11 are sleeved on the axial direction of the fixed shaft 9. The annular spoilers 11 are spaced apart from each other, and adjacent annular spoilers 11 are staggered with each other. The staggered arrangement of the annular spoilers 11 facilitates effective flow disturbance of the oil, improves the flow disturbance effect, and increases the residence time of the liquid flow in the filter, thereby facilitating the magnetic filter element 2 to adsorb metal particles in the oil.

[0056] A permanent magnet block 12 is sandwiched between adjacent annular spoilers 11. The permanent magnet block 12 is sleeved on the fixed shaft 9. The adjacent annular spoilers 11 are tightly fitted to the permanent magnet block 12. The permanent magnet block 12 can effectively adsorb and filter metal particles in the oil, thereby improving the metal particle contamination of the system oil. At the same time, it avoids damage to the gearbox and ensures normal system oil pressure.

[0057] A copper ring 13 is provided between the annular spoilers 11 between adjacent permanent magnet blocks 12. The copper ring 13 is sleeved on the fixed shaft 9. By providing the copper ring 13, sufficient gaps are maintained between the annular spoilers 11 between adjacent permanent magnet blocks 12, ensuring a larger working area and facilitating better adsorption of metal particles in the oil.

[0058] The adjacent permanent magnet blocks 12 have the same magnetic poles, and during installation, the permanent magnet blocks 12 with the same magnetic poles need to be installed together to avoid repulsion.

[0059] The filter cartridge 1 comprises a side-outlet filter cartridge 14 and a straight-outlet filter cartridge 15 . The side-outlet filter cartridge 14 and the straight-outlet filter cartridge 15 can adapt to different working environments, thereby increasing the applicable range of the filter.

[0060] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 The magnetic filter element 2 is also a deflection type magnetic filter element 16, which has a magnetic core cylinder 17. The inner axial direction of the magnetic core cylinder 17 is provided with a first cylinder tile 18, a second cylinder tile 19, a first stator magnetic tile 20 and a second stator magnetic tile 21. The first cylinder tile 18 and the second cylinder tile 19 are symmetrical to each other, and the first stator magnetic tile 20 and the second stator magnetic tile 21 are symmetrical to each other.

[0061] The first cylinder tile 18, the second cylinder tile 19, the first stator magnetic tile 20 and the second stator magnetic tile 21 are all evenly distributed along the circumferential direction of the inner wall of the magnetic core cylinder 17, and the outer walls of the first cylinder tile 18, the second cylinder tile 19, the first stator magnetic tile 20 and the second stator magnetic tile 21 are all fixedly connected to the inner wall of the magnetic core cylinder 17, so that the first stator magnetic tile 20 and the second stator magnetic tile 21 are fixed to the magnetic core cylinder 17, which is convenient for providing a magnetic field, and the first stator magnetic tile 20 and the second stator magnetic tile 21 are limited by the first cylinder tile 18 and the second cylinder tile 19.

[0062] A number of bolts 22 are provided on the outside of the magnetic core cylinder 17. The first cylinder tile 18, the second cylinder tile 19, the first stator magnetic tile 20 and the second stator magnetic tile 21 are detachably fixed to the inner wall of the magnetic core cylinder 17 by a number of bolts 22, which facilitates disassembly and assembly, and is beneficial for the staff to clean the metal particles adsorbed on the deflected magnetic filter element 16 later.

[0063] A rotatable rotor 23 is provided on the inner axial direction of the first cylindrical tile 18, the second cylindrical tile 19, the first stator magnetic tile 20 and the second stator magnetic tile 21. A magnetic rod 24 is fixedly connected to the outer wall of the rotor 23. The magnetic rod 24 and the first cylindrical tile 18, the second cylindrical tile 19, the first stator magnetic tile 20 and the second stator magnetic tile 21 are clearance-matched with each other. When the magnetic poles of the magnetic rod 24 of the rotor 23 rotate to the same direction as the magnetic poles of the first cylindrical tile 18, the second cylindrical tile 19, the first stator magnetic tile 20 and the second stator magnetic tile 21, the magnetic poles are different and the same. "Opposites repel each other", the external magnetic circuit is opened, the magnetic field is loaded, and the deflection type magnetic filter element 16 maintains its adsorption capacity, which is convenient for adsorbing metal particles in the oil; when the magnetic poles of the magnetic rod 24 of the rotor 23 rotate to the same and opposite poles as the first cylindrical tile 18, the second cylindrical tile 19, the first stator magnetic tile 20 and the second stator magnetic tile 21, the magnetic poles are opposite and "opposites attract each other", the external magnetic circuit is closed, the magnetic field is unloaded, and the deflection type magnetic filter element 16 loses its adsorption capacity, which is convenient for the metal particles or impurities adsorbed by the deflection type magnetic filter element 16 to be peeled off by themselves.

[0064] An end cover 25 is provided at the end of the rotor 23 away from the magnetic rod 24. The end of the rotor 23 away from the magnetic rod 24 passes through the axis of the end cover 25. The outer edge of the end cover 25 is fixedly connected to the end of the magnetic core cylinder 17. The end cover 25 provides a rotatable mounting platform for the rotor 23, allowing the rotor 23 to rotate along the axis of the magnetic core cylinder 17 and at the same time has a positioning effect on the rotor 23.

[0065] A rotating slip ring 26 is provided on the side of the end cover 25 away from the magnetic rod 24. The rotating slip ring 26 is rotatably connected to the opening of the filter cartridge 1. The end of the rotor 23 away from the magnetic rod 24 is fixedly connected to the axis of the rotating slip ring 26. The diameter of the rotating slip ring 26 is larger than that of the rotor 23, which is conducive to providing rotational force, thereby enabling the rotor 23 to rotate continuously.

[0066] The magnetic core cylinder 17 has a number of annular fins 27, and a number of adjacent annular fins 27 are staggered with each other. The annular fins 27 are evenly distributed along the axial direction of the first cylinder tile 18, the second cylinder tile 19, the first stator magnetic tile 20 and the second stator magnetic tile 21. The staggered distribution of the annular fins 27 can have the effect of disturbing the flow, increase the retention time of the liquid flow in the filter, and facilitate the deflection type magnetic filter element 16 to adsorb metal particles in the oil. The uniform distribution of the annular fins 27 along the axial direction of the first cylinder tile 18, the second cylinder tile 19, the first stator magnetic tile 20 and the second stator magnetic tile 21 makes the deflection type magnetic filter element 16 have more adsorption area, which is convenient for fully adsorbing metal particles in the oil.

At this time, the deflection type magnetic filter element 16 is in the "working state" as a whole, and the magnetic field is shown as follows: Figure 6 ;

[0068] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In this embodiment, when the magnetic poles of the magnetic rod 24 of the rotor 23 rotate to the same or opposite poles as the first cylindrical tile 18, the second cylindrical tile 19, the first stator magnetic tile 20 and the second stator magnetic tile 21, the magnetic poles are opposite and "opposites attract each other", the external magnetic circuit is closed, the magnetic field is unloaded, and the deflection type magnetic filter element 16 loses its adsorption capacity, so that the metal particles or impurities adsorbed by the deflection type magnetic filter element 16 can be peeled off by themselves.
