[0028] To further elaborate on the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following, in combination with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0029] Please refer to Figure 1-6 As shown, the present invention provides a vegetable oil filter, including an outer cylinder 1. A filter screen 2 is arranged inside the outer cylinder 1. The filter screen 2 is in the shape of a hollow cylinder. A flow regulating mechanism 3 is arranged inside the outer cylinder 1. The flow regulating mechanism 3 is used to adjust the speed of filtration.

[0030] The flow regulating mechanism 3 includes a trapezoidal block 37. A plurality of square openings corresponding to the trapezoidal block 37 are opened at the bottom of the outer cylinder 1. The trapezoidal block 37 is located above the square openings. The flow regulating mechanism 3 further includes a driving component, and the driving component is used to drive the trapezoidal block 37 to move.

[0031] Please refer to Figure 2 、 Figure 4 As shown, the driving component includes a connecting ring 36. The connecting ring 36 is rotatably connected to the trapezoidal block 37. A connecting frame 34 is fixedly connected to the connecting ring 36. One end of the connecting frame 34 away from the connecting ring 36 is fixedly connected to a fixed ring 33. A rotating shaft 32 is rotatably connected inside the outer cylinder 1. The fixed ring 33 and the rotating shaft 32 are slidably connected through a positioning key. A fixed cylinder 38 is arranged inside the outer cylinder 1. A circulation groove 35 is arranged on the fixed cylinder 38. The connecting frame 34 is slidably connected to the circulation groove 35. A first motor 31 is installed at the top of the filter screen 2. The output end of the first motor 31 is fixedly connected to the rotating shaft 32.

[0032] The provided flow control mechanism 3 can control the treatment speed of sewage, thereby adjusting the residence time of sewage in the filter according to the pollution degree of the sewage. By driving the rotation of the rotating shaft 32 with the first motor 31, the rotating shaft 32 further drives the fixed ring 33 that is slidably connected thereto to rotate, and the fixed ring 33 further drives the connecting frame 34 fixed thereto to rotate. Since the connecting frame 34 is slidably connected in the circulation groove 35 on the fixed cylinder 38, the connecting frame 34 rises and falls along the path of the circulation groove 35 while rotating. Since the connecting frame 34 is rotatably connected to the trapezoidal block 37, the trapezoidal block 37 moves within the square opening. As the position of the trapezoidal block 37 within the square opening is different, the contact area with the square opening is different, thereby controlling the size of the square opening, and finally completing the function of controlling the sewage discharge speed.

[0033] Please refer to Figure 2 、 Figure 3 As shown in the figure, a vibration assembly is provided on the rotating shaft 32. The vibration assembly is used to shake off the impurities adsorbed on the filter screen 2. The vibration assembly includes a square cylinder 301. A plurality of square cylinders 301 are provided and fixedly connected to the rotating shaft 32. A sliding rod 302 is slidably connected within the square cylinder 301. A spring 303 is provided within the square cylinder 301. The spring 303 is connected to the sliding rod 302. The sliding rod 302 extends to the outside of the square cylinder 301 and is equipped with a roller 304. The provided roller 304 can prevent the sliding rod 302 from directly contacting the filter screen 2. The friction between the sliding rod 302 and the filter screen 2 is relatively large, causing damage to the filter screen 2.

[0034] The provided vibration assembly is used to clean the impurities adhered to the filter screen 2. Since the square cylinder 301 on the vibration assembly is fixedly connected to the rotating shaft 32, the rotation of the rotating shaft 32 drives the square cylinder 301 to rotate synchronously. The sliding rod 302 slidably connected within the square cylinder 301 undergoes repeated telescoping under the stretching of the spring 303. When the roller 304 on the sliding rod 302 hits the filter screen 2, the impurities on the filter screen 2 are shaken off.

[0035] Please refer to Figure 5 、 Figure 6 As shown in the figure, a scraping mechanism 4 is provided within the outer cylinder 1. The scraping mechanism 4 includes a second motor 41. The outer cylinder 1 is an open structure. The top of the outer cylinder 1 is equipped with an upper cover 13. The second motor 41 is installed on the upper cover 13. The output end of the second motor 41 is fixedly connected to a turntable 42. A plurality of scraping plates 43 are fixedly connected to the turntable 42. The scraping plates 43 are in contact with the surface of the filter screen 2.

[0036] Please refer to Figure 6As shown in the figure, one end of the scraper 43 close to the bottom of the outer cylinder 1 is fixedly connected with a connecting plate 44. The connecting plate 44 contacts the bottom of the outer cylinder 1. A sewage outlet 9 is provided at the bottom of the outer cylinder 1. A ball valve 7 is rotatably connected in the sewage outlet 9. A cylindrical hole is provided on the ball valve 7. A third motor 6 is installed on the outer cylinder 1. The output end of the third motor 6 is fixedly connected with the ball valve 7.

[0037] The provided scraping mechanism 4 drives the turntable 42 to rotate through the second motor 41. The turntable 42 further drives the scraper 43 fixed thereto to rotate synchronously. The rotation of the scraper 43 scrapes off the impurities on the filter screen 2. At the same time, the connecting plate 44 on the scraper 43 rotates synchronously. The scraped impurities fall to the bottom of the outer cylinder 1. The connecting plate 44 pushes the impurities into the sewage outlet 9. The ball valve 7 is provided in the sewage outlet 9. When the filter is filtering, in order to prevent the sewage from being discharged from the sewage outlet 9, at this time, the cylindrical hole of the ball valve 7 is perpendicular to the direction of the sewage outlet 9, so that the sewage is blocked by the ball valve 7. When the filtering is over, the third motor 6 is started to drive the ball valve 7 to rotate, aligning the cylindrical hole on the ball valve 7 with the outlet direction of the sewage outlet 9, so as to discharge the impurities.

[0038] Please refer to Figure 1 As shown in the figure, a water outlet 8 is provided at the bottom of the outer cylinder 1. The water outlet 8 is used to discharge the sewage after impurity removal. An inlet 5 corresponding to the water outlet 8 is provided at the upper part of the outer cylinder 1. A plurality of fixing seats 11 are installed on the outer cylinder 1. A positioning seat matching with the fixing seats 11 is provided on the upper cover 13. A rotating rod 12 is rotatably connected to the fixing seats 11. External threads are provided on the rotating rod 12. A threaded seat is threadedly connected to the rotating rod 12. Through the cooperation of the rotating rod 12 and the threaded seat, the upper cover 13 and the outer cylinder 1 are fixed together.
