[0002] Vegetable oils are compounds formed by the combination of unsaturated fatty acids and glycerol. Widely distributed in nature, they are obtained from the fruits, seeds, and germs of plants. Vegetable oils are widely used in health products, which require even higher quality. During the production process, vegetable oils contain some residue, necessitating filtration before use or consumption. Common filtration methods include sedimentation filtration, centrifugation, and pressure filtration. Centrifugation uses centrifugal force to separate impurities from the oil. Centrifugation is highly efficient, suitable for processing large quantities of oil, and produces low oil content in the filter residue, making it widely used in vegetable oil production filtration.
[0003] However, the filter cartridges in existing centrifugal filtration devices for vegetable oil are difficult to clean. After prolonged use, the residue from the filtered vegetable oil will adhere to the inner wall of the filter cartridge. If not cleaned, it will affect the filtration effect of the filter cartridge and lead to a decline in the quality of the produced vegetable oil. Utility Model Content

[0016] Beneficial effects
[0017] This utility model provides a multi-stage centrifugal filtration device for vegetable oil, which has the following beneficial effects:
[0018] 1. By installing a tank, vegetable oil can be filtered inside the tank. By installing a first filter cylinder, rotating the first filter cylinder can separate the vegetable oil from the residue under the action of centrifugal force.

By installing a first cleaning component, the filter cylinder can be cleaned. By installing a lifting rod, the lifting rod can drive the semi-circular scraper to rise. When the lifting rod rises to the hinge point above the upper surface of the fixed plate, the pair of semi-circular scrapers can be folded open under the action of the tension spring until the scraper contacts the inner wall of the first filter cylinder. The lifting rod continues to rise, driving the scraper to rise, thus cleaning the inner wall of the first filter cylinder and cleaning the residue attached to the inner wall of the filter cylinder.

The filtered oil is thrown out of the first filter cylinder 2, while the residue produced after filtration is retained in the first filter cylinder 2, thus separating the vegetable oil. The first cleaning component is installed to clean the filter cylinder. The lifting rod 10 is installed and its rise can drive the semi-circular scraper 11 to rise. When the lifting rod 10 rises to the hinge point above the upper surface of the fixed plate 4, the pair of semi-circular scrapers 11 can be folded open under the action of the tension spring 14 until the scrapers 11 contact the inner wall of the first filter cylinder 2. The lifting rod 10 continues to rise to drive the scrapers 11 to rise, thus cleaning the inner wall of the first filter cylinder 2 and removing the residue attached to the inner wall of the filter cylinder.

[0032] Furthermore, a first gear 9 is rotatably mounted on the tank 1 located inside the cleaning chamber, and the lifting rod 10 is provided with teeth that mesh with the first gear 9.

[0034] Furthermore, a pair of second gears 17 are rotatably mounted on the tank body 1 near a pair of lifting plates 18, and the lifting plates 18 are provided with teeth that mesh with the second gears 17.
[0035] The second gear 17 is installed, and the drive motor 5 is started to drive the second gear 17 to rotate. The second gear 17 meshes with the teeth to drive the lifting plate 18 to rise and fall, thereby driving the scraper ring 19 to rise and fall.
[0036] Furthermore, an external gear ring 6 is fixedly installed on the top of the first filter cylinder 2, and an internal gear ring 7 is fixedly installed on the top of the second filter cylinder 3. Both the internal gear ring 7 and the external gear ring 6 are rotatably connected to the top of the tank body 1. A third gear 8 that meshes with both the internal gear ring 7 and the external gear ring 6 is rotatably installed on the top of the tank body 1. A motor 5 for driving the third gear 8 to rotate is fixedly installed on the tank body 1.
[0037] The motor 5 is installed, and starting the motor 5 can drive the third gear 8 to rotate. The third gear 8 meshes with the inner gear ring 7 and the outer gear ring 6, which can drive the first filter cylinder 2 and the second filter cylinder 3 to rotate together, thereby enabling multi-stage filtration of vegetable oil at the same time.
[0038] Furthermore, an oil inlet pipe 15 is fixedly connected to the top of the tank body 1, through which the vegetable oil to be filtered can be introduced into the tank body 1.
[0039] Furthermore, a second waste discharge pipe 21 is fixedly connected to the bottom of the tank body 1, and a waste discharge port 20 is opened on the bottom wall of the tank body 1. The cleaning chamber and the second waste discharge pipe 21 are connected through the waste discharge port 20.

[0043] By providing a first row of miscellaneous pipes 16, the residue in the filtration chamber can be discharged into the cleaning chamber through several first row of miscellaneous pipes 16. By providing a valve, vegetable oil can be prevented from falling into the cleaning chamber when filtering vegetable oil.
[0044] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires, and should select appropriate controllers according to actual conditions to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical connections between the various electrical components are completed in sequence. The detailed connection methods are well-known technologies in the field. The following mainly introduces the working principle and process, and will not describe the electrical control further.
[0045] The working principle and usage process of this utility model are as follows: In use, the vegetable oil to be filtered is introduced into the tank 1 through the oil inlet pipe 15. The motor 5 is started, driving the third gear 8 to rotate. The third gear 8 meshes with both the inner and outer gear rings 7 and 6, causing them to rotate together. This, in turn, drives the first filter cylinder 2 and the second filter cylinder 3 to rotate, thus filtering the vegetable oil. The residue produced after filtration remains in the first and second filter cylinders 2 and 3. The filtered vegetable oil, after passing through the first and second filter cylinders 2 and 3, remains in the cavity between the second filter cylinder 3 and the tank 1 wall. It can then be discharged through the oil drain pipe 22. When it is necessary to clean the residue in the first filter cylinder 2, the drive motor 5 is started, driving the first gear 9 to rotate. The toothed gear engages with the lifting rod 10, which in turn raises a pair of semi-circular scrapers 11. The scrapers 11 then unfold under the action of the tension spring 14. The lifting rod 10 continues to rise, which in turn raises the pair of semi-circular scrapers 11, thus cleaning the inner wall of the first filter cylinder 2. The scraps that fall off can fall onto the fixed plate 4. When it is necessary to clean the second filter cylinder 3, the drive motor 5 is started, which drives the second gear 17 to rotate, thereby raising and lowering a pair of lifting plates 18, which in turn raises and lowers the scraper ring 19, thus cleaning the inner wall of the second filter cylinder 3. The cleaned scraps also fall onto the fixed plate 4. The valve on the first waste pipe 16 is opened, and the scraps on the fixed plate 4 are discharged into the cleaning chamber through the first waste pipe 16. After falling to the bottom of the tank body 1, all the scraps inside the tank body 1 can be discharged through the second waste pipe 21.
[0046] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
