[0024] Such as Figures 1 - 7As shown in the figure, it shows an airtight self-unloading filter for animal fats in an embodiment of the present disclosure, including a filter box 1. A flow guide frame 21 is fixedly connected inside the filter box 1. An outlet and an inlet are respectively formed on both sides of the filter box 1. A discharge pipe 22 is fixedly connected at the outlet. A filter screen 2 is fixedly connected inside the filter box 1. It further includes: a sealing discharge plate 3, a lower pressing plate 4, and a feeding mechanism. There are three sealing discharge plates 3. Cleaning ports are formed on both sides of the filter box 1. Flow guide boxes 20 are fixedly connected at both cleaning ports. Two of the sealing discharge plates 3 are arranged at the cleaning ports through a moving mechanism, which is used to clean the grease residues on the filter screen 2. The lower pressing plate 4 is arranged inside the filter box 1 through a pressure filtration mechanism and can press down the oil to be filtered. The feeding mechanism is arranged on one side of the filter box 1 and can transport the boiled oil into the filter box 1. The three sealing discharge plates 3 are driven to move through the moving mechanism, so as to push the grease residues filtered out on the filter plate out of the cleaning port. The lower pressing plate 4 is driven to press down through the pressure filtration mechanism, thereby improving the filtration efficiency of the grease residues. Through the cooperation among the sealing discharge plate 3, the lower pressing plate 4, the moving mechanism, the pressure filtration mechanism, and the feeding mechanism, it can replace the operator to quickly clean the grease residues on the filter screen 2, which is relatively time-saving and labor-saving, and improves the cleaning efficiency and effect of the grease residues.

[0025] In order to drive the sealing discharge plate 3 to move inside the filter box 1 and push the grease residues on the filter plate out of the cleaning port, the moving mechanism includes: a connecting plate 5, a tooth rack 6, and a driving component. The connecting plate 5 is fixedly connected to two of the sealing discharge plates 3 close to one side of the filter box 1. The other two sealing discharge plates 3 close to the other side of the filter box 1 are respectively located at the two cleaning ports. The tooth rack 6 is fixedly connected to the connecting plate 5 and one of the sealing discharge plates 3. The tooth rack 6 is slidably connected to one side of the filter box 1. The driving component is arranged on one side of the filter box 1 and can drive the tooth rack 6 and multiple sealing discharge plates 3 to move synchronously. The driving component includes: a driving gear 7 and a first motor 8. The driving gear 7 is arranged on one side of the tooth rack 6 and meshes with the tooth rack 6. The first motor 8 is installed on one side of the filter box 1, and the output end of the first motor 8 is fixedly connected to the driving gear 7. The driving gear 7 is driven to rotate by the first motor 8. When the driving gear 7 rotates, it drives the tooth rack 6 to move. When the tooth rack 6 moves, it drives the connecting plate 5 and the three sealing discharge plates 3 to move, so that the sealing discharge plate 3 pushes the grease residues on the filter plate out of the cleaning port and into the flow guide box 20.

[0026] In order to improve the efficiency and effect of grease residue filtration, the pressure filtration mechanism includes: a sliding rod 9, a sliding frame 10, a support spring 11, a rotating wheel 12 and a power assembly. The sliding rod 9 is fixedly connected to the top end of the lower pressing plate 4. A sliding hole is formed in the filtration box 1, and the sliding rod 9 is slidably connected in the sliding hole. There are two sliding frames 10. A sliding groove is formed in the sliding rod 9, and both sliding frames 10 are slidably connected in the sliding groove. Support springs 11 are fixedly connected to both sliding frames 10, and both support springs 11 are fixedly connected to the inner wall of the sliding groove. Rotating wheels 12 are rotatably connected to both sliding frames 10. The power assembly is arranged at the top end of the filtration box 1 and can drive the sliding rod 9 to move up and down. The power assembly includes: a driving frame 13, a lifting frame 14, a driving wheel 15 and a first electric cylinder 16. A rotating seat 23 is fixedly connected to the top end of the filtration box 1. The bottom end of the driving frame 13 is rotatably connected to the top end of the filtration box 1 through the rotating seat 23. The other end of the driving frame 13 penetrates through the sliding groove and extends to one side of the sliding groove. Both sides of the driving frame 13 are respectively in contact with the circumferential surfaces of the two rotating wheels 12. The lifting frame 14 is slidably connected to the top end of the filtration box 1. There are two driving wheels 15, and both driving wheels 15 are rotatably connected to one side of the lifting frame 14. Both sides of the two driving wheels 15 are respectively in contact with both sides of the driving frame 13. The first electric cylinder 16 is installed on one side of the filtration box 1, and the output end of the first electric cylinder 16 is fixedly connected to the lifting frame 14. When the first electric cylinder 16 installed on the filtration box 1 drives the lifting frame 14 to descend, when the lifting frame 14 descends, the driving wheels 15 rotatably connected to the lifting frame 14 press against the driving frame 13, pressing down the driving frame 13, thereby driving the driving frame 13 to swing. When the driving frame 13 swings, it presses against one of the driving wheels 15 close to the bottom end, and drives the sliding rod 9 and the lower pressing plate 4 to descend through the support of the support spring 11, thereby performing pressure filtration on the oil and improving the filtration efficiency of the oil.

[0027] In order to convey the oil after boiling into the filtration box 1, the feeding mechanism includes: a delivery pump 17, a delivery pipe 18 and a feeding pipe 19. The delivery pump 17 is installed on one side of the filtration box 1. The bottom end of the delivery pipe 18 is communicated with the output end of the delivery pump 17, and the top end of the delivery pipe 18 is communicated with the feeding port. One end of the feeding pipe 19 is communicated with the input end of the delivery pump 17. When it is necessary to convey the boiled oil into the filtration box 1, the delivery pump 17 pumps out the boiled oil through the feeding pipe 19 and conveys the oil into the filtration box 1 through the delivery pipe 18, so that the oil falls on the filter plate.

[0028] Working principle: When it is necessary to filter the boiled oil, start the delivery pump 17. The delivery pump 17 pumps out the boiled oil through the feeding pipe 19 and transports the oil into the filter box 1 through the delivery pipe 18, so that the oil falls on the filter plate. Then start the first electric cylinder 16. The first electric cylinder 16 installed on the filter box 1 drives the lifting frame 14 to descend. When the lifting frame 14 descends, the driving wheel 15 rotatably connected to the lifting frame 14 abuts against the driving frame 13, pressing down the driving frame 13, thereby driving the driving frame 13 to swing. When the driving frame 13 swings, it abuts against a rotating ring near the bottom end, and drives the sliding rod 9 and the lower pressing plate 4 to descend through the support of the support spring 11, so as to press-filter the oil, improving the filtering efficiency of the oil. After filtering the oil, the first electric cylinder 16 moves in the reverse direction, thereby driving the lifting frame 14 to rise. When the lifting frame 14 rises, a driving wheel 15 near the bottom end rotatably connected to the lifting frame 14 abuts against the driving frame 13 and pushes it upward, thereby driving the driving frame 13 to swing upward, so that the driving frame 13 abuts against the rotating wheel 12 near the top end, and through the support of the support spring 11, drives the sliding rod 9 and the lower pressing plate 4 to rise. Then drive the driving gear 7 to rotate through the first motor 8. When the driving gear 7 rotates, it drives the tooth rack 6 to move. When the tooth rack 6 moves, it drives the connecting plate 5 and the three sealing discharge plates 3 to move, so that the sealing discharge plates 3 push the grease residue on the filter plate out of the cleaning port and fall into the diversion box 20, thereby realizing the rapid cleaning of the grease residue on the filter plate.

[0029] It should also be noted that when the sealing discharge plate 3 is at the cleaning port, the sealing discharge plate 3 and the cleaning port are in a sealed state. Therefore, when the lower pressing plate 4 presses down, there will be no oil leakage at the cleaning port.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present disclosure and not to limit them. Although the present disclosure has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present disclosure can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present disclosure, and they should all be covered by the scope of the claims of the present disclosure.
