Description

Technical Field

[0001] The utility model relates to the technical field of filtering devices, in particular to a filtering device used for cottonseed oil pressing. Background Art

[0002] Natural ester insulating oil is a high-ignition-point insulating oil, which is a flame-retardant insulating oil. Its ignition point is much higher than that of mineral oil, and its ignition time, smoke generation rate, diffusion rate and other indicators are better than mineral insulating oil. It has very excellent flame retardant properties, which can effectively prevent fire accidents caused by transformer overload, short circuit and other faults, and reduce losses. Cottonseed-based natural ester insulating oil has a lower pour point and viscosity, and better transformer energy efficiency. It is widely used in power grid companies and new energy projects such as offshore wind power at home and abroad.

[0003] Publication No. CN219209286U discloses a transformer oil filter device, including a filter structure and a sedimentation structure, wherein the filter structure includes a housing, a coarse filter and a fine filter, wherein the coarse filter is slidably connected to the inside of the housing, wherein the fine filter is slidably connected to the inside of the housing, wherein the sedimentation structure includes a shaking member and an oil extractor, wherein the oil extractor is fixed inside the shaking member, wherein the shaking member includes a fixed shaft, wherein the fixed shaft is fixed inside the housing, wherein one side of the fixed shaft is rotatably connected to an oil collecting box, wherein one side of the oil collecting box is fixed with a spring tube, wherein one side of the oil collecting box is rotatably connected to a rotating shaft, wherein one side of the rotating shaft is fixed with a connecting rod, wherein one side of the connecting rod is rotatably connected to an eccentric wheel, wherein a first motor is fixed inside the eccentric wheel, wherein the first motor is fixed to one side of the housing. Although this type of filter device uses a motor to drive the eccentric wheel, and then uses a connecting rod to allow the oil collecting box to quickly and slightly shake, thereby being able to precipitate the transformer oil. However, in this type of filtering device, the inclined filter plate relies on gravity to slide out the residue, and the residue is easily stuck, requiring frequent manual intervention, high operation frequency, and low work efficiency. At the same time, the residue is easy to scatter during the inclined sliding process, and the cleaning is not thorough, affecting the cleanliness of the equipment and the operating environment. In addition, when the residue slides out of the inclined filter plate, some transformer oil may flow out, resulting in oil leakage, causing resource waste and environmental pollution. Therefore, improvements are needed. Utility Model Content

[0028] Working principle: After entering the cottonseed-based natural ester insulating oil through the oil inlet pipe 14, the cottonseed-based natural ester insulating oil can be filtered by the filter plate 4. When the filtered residue needs to be cleaned, the staff only needs to turn on the top motor 2, and the top motor 2 can then drive the rotating rod 3 and the filter plate 4 to rotate. During the rotation of the filter plate 4, the residue on the surface can be blocked by the dirt bent plate 6. After the filter plate 4 rotates one circle, the residue on the surface can be accumulated on the inner side of the bent plate 6. Then the staff only needs to pull the pull block 10 to drive the insertion rod 9 to leave the socket 12. At this time, the limit of the mounting block 7 can be released. Then, it is only necessary to pull the mounting block 7 outward. The mounting block 7 then drives the bent plate 6 to move outward, and the residue can be pushed out of the mounting block. The groove 5 is driven by the top motor 2 to drive the rotating rod 3 and the filter plate 4 to rotate, thereby removing the residue. After the residue is removed, the mounting block 7 is pushed into the mounting groove 5 again, and then the pulling block 10 is released. Subsequently, due to the tension of the tension spring 11, the tension spring 11 can pull the pulling block 10 to move, and the pulling block 10 then drives the plugging rod 9 to insert into the insertion hole 12. At this time, the position of the mounting block 7 and the bent plate 6 can be limited. The utility model drives the rotating rod 3 and the filter plate 4 to rotate through the top motor 2 to realize automatic residue cleaning, reduce the frequency of manual operation, and improve work efficiency. After the filter plate 4 rotates one circle, the residue on the surface is blocked by the bent plate 6 and accumulated on the inner side of the bent plate 6, avoiding the scattering of the residue, ensuring that the cleaning process is efficient and tidy, and at the same time, through the simple operation of the pulling block 10 and the plugging rod 9, the workers can The staff can easily release and restore the limit of the mounting block 7 to quickly clean up the residue, and the operation is simple and easy. At the same time, since the filter plate 4 is sealed inside the housing 1, the cottonseed-based natural ester insulating oil can be prevented from leaking during the filtering process. The cottonseed-based natural ester insulating oil enters through the oil inlet pipe 14, and then the cottonseed-based natural ester insulating oil can be blocked by the filter plate 4, and then slowly passes through the filter plate 4 and falls into the bottom end of the housing 1. At this time, the cottonseed-based natural ester insulating oil can be filtered, and then the bottom motor 17 is turned on, and the bottom motor 17 can then drive the disc 18 to rotate, and the disc 18 can then drive the magnet 19 to rotate, and the magnet 19 can then rotate in the cottonseed-based natural ester insulating oil. At this time, the metal impurities in the cottonseed-based natural ester insulating oil can be adsorbed, thereby further filtering the cottonseed-based natural ester insulating oil, and then the cottonseed-based natural ester insulating oil is allowed to stand to allow the stains therein to settle, and then the filtered cottonseed-based natural ester insulating oil can be discharged through the oil outlet pipe 15. The utility model uses the filter plate 4 for preliminary filtration, which further improves the purification effect of the oil and ensures the preliminary removal of large particles of impurities. The rotating magnet 19 adsorbs metal impurities to further purify the oil, which can effectively remove metal particles in the oil and improve the insulation performance and service life of the oil. The stains therein are naturally precipitated by standing the oil, and fine impurities are removed through the standing process, ensuring that the filtered oil is purer.
