[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the following combines specific embodiments to further elaborate the present utility model. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the implementation manners, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present utility model.

[0023] For the embodiments, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown in the figure, the utility model provides a small mill sesame oil production filtration and purification device, including a filtration device 1. Inside the filtration device 1, there is an oil storage bin 2. On the inner wall of the oil storage bin 2, there is a fixed ring 4. At the top of the fixed ring 4, there is an inner tank 5 placed. At the center of the bottom end of the inner tank 5, there is a limit disk 6. A filtration screen sleeve 10 is sleeved on the surface of the limit disk 6. A fine filter screen sleeve 11 is sleeved on the surface of the filtration screen sleeve 10. At the bottom end of the inner tank 5, there is a support ring 7 placed. On the top of the support ring 7, multiple layers of filter screen brackets 8 are stacked in sequence. The multiple layers of filter screen brackets 8 are all sleeved outside the fine filter screen sleeve 11. On the inner side of the grooves on the top surface of the support ring 7 and the top surface of the filter screen brackets 8, there is a coarse filtration filter screen 9 laid. On the outer ring surface of the filter screen brackets 8, oil inlet holes 12 are evenly opened. On the top surface of the inner ring of the filter screen brackets 8, oil outlet grooves 13 are evenly opened. At the top of the inner tank 5, there is a pressing disk 14. At the center of the bottom end of the pressing disk 14, there is a limit groove opened. On the top of the pressing disk 14, there is a top cover 15 installed. At the connection between the top cover 15 and the filtration device 1, there is a flange lock catch 17. At the center of the bottom end of the oil storage bin 2, there is a hollow oil extraction pipe 3. The top end of the hollow oil extraction pipe 3 sequentially penetrates through the inner tank 5 and the center of the limit disk 6 and extends to the inside of the limit groove opened at the center of the bottom end of the pressing disk 14. Through holes are staggered and opened on both side surfaces of the hollow oil extraction pipe 3. When the crude sesame oil enters the inside of the inner tank 5, it enters the inside of the filter screen brackets 8 through the oil inlet holes 12 opened on the outer ring of the filter screen brackets 8. At this time, the larger impurities in the crude sesame oil are filtered by the coarse filtration filter screen 9 and flow through the surface of the fine filter screen sleeve 11 through the oil outlet grooves 13 opened at the top of the inner ring of the filter screen brackets 8. The coarsely filtered sesame oil is finely filtered by the fine filter screen sleeve 11 and flows into the inner cavity of the filtration screen sleeve 10 through the round holes on the surface of the filtration screen sleeve 10. At this time, the sesame oil in the inner cavity of the filtration screen sleeve 10 flows into the inside of the oil storage bin 2 through the through holes on the surface of the hollow oil extraction pipe 3 to complete the filtration. The setting of the multiple layers of filter screen brackets 8 and the multiple layers of coarse filtration filter screens 9 makes the dispersion filtration and purification efficiency of the crude oil higher. At the same time, the setting of the filtration screen sleeve 10 and the fine filter screen sleeve 11 finely filters out the fine impurities from the coarsely filtered sesame oil, making the purity of the sesame oil higher.

[0024] As Figure 1As shown in the figure, an oil extraction pump 19 is installed at the bottom end of the hollow oil extraction pipe 3. An oil outlet pipe 21 is installed on one side of the oil extraction pump 19. One side surface of the top end of the filtering device 1 is provided with an oil delivery pipe 22. A U-shaped groove is opened on one side surface of the top end of the inner tank 5. One end of the oil delivery pipe 22 penetrates through the filtering device 1 and extends to the inside of the U-shaped groove opened on one side surface of the top end of the inner tank 5. The other end of the oil delivery pipe 22 is installed with an oil delivery pump 18. An oil inlet pipe 23 is installed on one side of the oil delivery pump 18. The oil delivery pump 18 and the oil extraction pump 19 are installed inside the bottom end of the filtering device 1. Through the combined setting of the hollow oil extraction pipe 3, the oil extraction pump 19, and the oil outlet pipe 21, the filtering and oil extraction efficiency of sesame oil is increased. Through the combined setting of the oil inlet pipe 23, the oil delivery pump 18, and the oil delivery pipe 22, the crude sesame oil continuously enters the inside of the inner tank 5, is filtered by the coarse filtering screen 9 and the fine filtering net sleeve 11, and then is output to the inside of the oil storage tank 2 through the hollow oil extraction pipe 3. The oil inlet pipe 23, the oil delivery pump 18, the oil delivery pipe 22, the inner tank 5, the hollow oil extraction pipe 3, the oil storage tank 2, the oil extraction pump 19, and the oil outlet pipe 21 form a complete loop, shortening the filtering time and improving the production efficiency of the purification and filtration of small mill sesame oil.
