[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] For example 1, please refer to Figures 1 to 15 A triacetin purification and processing device includes a cooling tank 1, a slide rail 2 is provided inside the cooling tank 1, a sliding block 3 is slidably provided inside the slide rail 2, a storage tank 4 is fixedly connected to the outer wall of the sliding block 3, and a partition 5 is fixedly connected to the interior of the storage tank 4; and further includes: The first flap 6 is rotatably mounted inside the partition 5. The side of the first flap 6 is movably connected to the second flap 7. The second flap 7 is slidably provided with a movable ball rod 9 inside. The bottom of the first flap 6 is provided with a first filter 27 for filtering liquid. The sliding groove 11 is provided inside the partition 5. The sliding groove 11 includes a lifting groove 1103. The end of the movable ball rod 9 is slidably disposed inside the lifting groove 1103. The outer portion of the movable ball rod 9 is sleeved with a positioning rod 10. The rotating disk 13 is rotatably mounted inside the partition 5. A groove 14 for slidingly connecting the positioning rod 10 is provided on the rotating disk 13. A driving part for driving the first flap 6 and the second flap 7 to fold is provided at the bottom of the rotating disk 13. The driving part includes a rotating shaft 17 fixedly connected to the outer wall of the rotating disk 13, the end of the rotating shaft 17 is fixedly connected to the connecting gear 18, the side of the connecting gear 18 is meshedly connected to the connecting rack 19, a positioning frame 20 is slidingly provided inside the connecting rack 19, the positioning frame 20 is fixedly connected to the sliding block 3, the end of the connecting rack 19 is fixedly connected to the push-pull rod 21, and a driving groove 22 is provided inside the slide rail 2 to limit the movement of the push-pull rod 21. The driving groove 22 includes a smooth portion 2201, an inclined portion 2202 and a reset portion 2203 that are connected to each other. The path length of the inclined portion 2202 is shorter than the path length of the reset portion 2203. A second filter screen 28 is provided in the middle of the partition 5, and a pulling wire 26 is fixedly provided on the outer wall of the slide rail 2; First, the movement of the slide rail 2 is controlled by the lifting device, and the storage tank 4 set on the slide rail 2 is sunk into the cooling tank 1 to realize cooling and crystallization of the liquid inside the storage tank 4 and remove impurities in the liquid. It should be noted that the lifting device for controlling the slide rail 2 can be a hydraulic rod, and those skilled in the art can select it according to actual needs. When the crystallization temperature is reached and the liquid inside the storage tank 4 is also crystallized, the pulling wire 26 set inside the control slide rail 2 is pulled, so that the sliding block 3 drives the storage tank 4 to slide inside the cooling tank 1, and the reciprocating motion of the storage tank 4 is used to move the liquid inside the storage tank 4, which is convenient for subsequent filtration and separation of the liquid and the crystals. It should be noted that the pulling wire 26 can be pulled by a take-up reel, which is a prior art, and those skilled in the art can select it according to actual needs. When the sliding block 3 drives the storage tank 4 to slide inside the slide rail 2, it will also drive the connecting gear 18 to slide inside the slide rail 2, and a positioning frame 20 is fixedly provided on the sliding block 3, and the positioning frame 20 is used to limit the connecting rack 19, so that the connecting rack 19 and the connecting gear 18 are always in a meshing state. When the connecting gear 18 and the connecting rack 19 follow the sliding block 3 to slide inside the slide rail 2, the push-pull rod 21 provided on the end of the connecting rack 19 will slide inside the driving groove 22. When the push-pull rod 21 slides from the smooth portion 2201 into the inclined portion 2202 At this time, the connecting rack 19 slides into the inside of the slide rail 2, allowing the connecting rack 19 to drive the connecting gear 18 to rotate clockwise. When the connecting gear 18 rotates, it drives the rotating shaft 17 and the rotating disk 13 to rotate inside the partition 5. The rotating disk 13 is provided with a connecting groove 14, and the positioning rod 10 is slidably arranged inside the positioning rod 10. By rotating the rotating disk 13, the positioning rod 10 slides inside the connecting groove 14. The positioning rod 10 is provided with a movable ball rod 9 inside, and then the positioning rod 10 drives the movable ball rod 9 to slide inside the lifting groove 1103 in the sliding groove 11; When the second flap 7 is moved, the second flap 7 is moved to the left of the second flap 7 and the second flap 7 is moved to the right of the first flap 7. When the second flap 7 is moved, the second flap 7 is moved to the right of the second flap 7 and the second flap 7 is moved to the left of the second flap 7. When the first and second flaps 6 and 7 are in the horizontal position, the channel on the first filter screen 27 is blocked. When the liquid impurities are cooled and crystallized, the first and second flaps 6 and 7 are opened. The first and second flaps 7 are gradually moved closer to each other to scrape the crystals on the first filter screen 27, thereby improving the liquid filtration rate. When the push-pull rod 21 slides from the inclined portion 2202 into the reset portion 2203, it drives the second flap 7 to reset. The plurality of inclined portions 2202 and reset portions 2203 are arranged to allow the second flap 7 to reciprocate and achieve the effect of reciprocating scraping of the first filter screen 27. Because the path of the inclined portion 2202 is smaller than the path of the reset portion 2203, the time for the reset portion inclined portion 2202 to reset to the reset portion 2203 is longer, thereby making the second flap 7 and the first flap 6 fold closer at a faster speed and reset at a slower speed. It should be noted that when the movable ball bar 9 slides inside the lifting groove 1103, the lifting groove 1103 is divided into a vertical groove and a horizontal groove. At this time, when the movable ball bar 9 slides inside the lifting groove 1103, it will only slide in the horizontal groove on the lifting groove 1103.

[0037] As an optional solution of the driving part of the present invention, the driving part includes a gear plate 23 fixedly connected to the outer wall of the rotating plate 13, the outer portion of the gear plate 23 is meshedly connected to the driving rack 24, and the end of the driving rack 24 is provided with an electric telescopic rod 25, which is fixedly connected to the partition 5; When the sliding block 3 drives the storage tank 4 to slide inside the slide rail 2, the electric telescopic rod 25 set at the bottom of the partition 5 is controlled, and the telescopic movement of the electric telescopic rod 25 is used to drive the driving rack 24 to reciprocate on the gear plate 23, thereby driving the rotating plate 13 to rotate forward and reverse. The forward and reverse rotation of the rotating plate 13 is used to open the channel on the pulling wire 26. At the same time, the movement of the second flap 7 on the first filter screen 27 is used to scrape the crystallized impurities on the first filter screen 27 to improve the filtering effect of the liquid. It should be noted that the driving rack 24 drives the gear plate 23 to move clockwise faster than the counterclockwise rotation speed of the gear plate 23, thereby making the second flap 7 and the first flap 6 fold closer faster and reset slower.

[0038] Example 2: This example is an improvement made on the basis of Example 2, which solves the problem that it is difficult to quickly increase the filtration rate by scraping the second flap when there are many crystal impurities on the first filter screen 27. For details, please refer to Figures 1 to 15, the sliding groove 11 also includes an inclined groove 1101 and a smooth groove 1102, the inclined groove 1101 and the smooth groove 1102 are connected, and the smooth groove 1102 and the lifting groove 1103 are connected. A limit block 15 is provided at the end of the lifting groove 1103, and a return spring 16 is fixedly connected to the bottom of the limit block 15. The limit block 15 is slidably arranged inside the partition 5. The positioning rod 10 includes a positioning sleeve rod 1001 sleeved on the outside of the active ball rod 9, and a sleeve 1003 is sleeved on the outside of the positioning sleeve rod 1001. A telescopic spring 1002 is provided between the positioning sleeve rod 1001 and the sleeve 1003, and a protrusion for stable sliding inside the connecting groove 14 is provided on the sleeve 1003; When the rotating disk 13 rotates, it drives the positioning rod 10 to rotate inside the connecting groove 14. The protrusion on the sleeve 1003 is embedded in the groove provided on the connecting groove 14, so that the sleeve 1003 can only slide left and right on the connecting groove 14. The sliding groove 11 is also provided with an inclined groove 1101 and a smooth groove 1102. When the rotating disk 13 rotates clockwise, the movable ball rod 9 is restricted by the limit block 15 and will first slide into the interior of the inclined groove 1101. Subsequently, as the rotating disk 13 continues to rotate, the movable ball rod 9 slides from the inside of the inclined groove 1101 to the inside of the smooth groove 1102. At this time, the movable ball rod 9 will drive the second flap 7 to fold closer to the first flap 6, and will lift the second flap 7 upward, thereby separating the second flap 7 from the first filter screen 27 in the process of the second flap 7 and the first flap 6 approaching each other. At the same time, because the movable ball rod 9 slides from the inclined groove 1101 to the inside of the smooth groove 1102, the positioning sleeve rod 1001 will slide inside the sleeve 1003 and squeeze the telescopic spring 1002. As the rotating disk 13 continues to rotate, the movable ball rod 9 will move to the end of the smooth groove 1102. Because the end of the smooth groove 1102 is connected to the vertical groove of the lifting groove 1103, the restoring elastic force of the telescopic spring 1002 drives the positioning sleeve rod 1001 to reset and slide inside the sleeve 1003, and finally allows the movable ball rod 9 to slide into the horizontal groove of the sleeve 1003, and allows the second flap 7 to fit the surface of the first filter screen 27; As the rotating disk 13 is reversed, the positioning rod 10 drives the movable ball rod 9 to reset inside the sleeve 1003, allowing the second flap 7 to slide on the surface of the first filter screen 27. The second flap 7 is used to slide on the first filter screen 27 to push the crystallized impurities on the first filter screen 27 and push them into the groove opened in the middle of the partition 5, so as to achieve the effect of scraping off the crystallized impurities on the first filter screen 27. Moreover, since the speed of the second flap 7 and the first flap 6 during the resetting process is slower than that during the folding process of the second flap 7 and the first flap 6, the slower resetting movement is used to allow the second flap 7 to scrape off the crystallized impurities on the first filter screen 27, thereby reducing the situation of uniformly scraping the liquid to the center of the partition 5 as much as possible. The situation of reducing the situation of scraping the liquid to the center of the partition 5 is when there is less liquid remaining on the first filter screen 27. When the movable ball rod 9 moves to the joint of the lifting groove 1103 and the inclined groove 1101, the movable ball rod 9 will squeeze the limit block 15, and while allowing the limit block 15 to move forward, it will compress the return spring 16 and finally allow the movable ball rod 9 to move to the top of the limit block 15. It should be noted that when the first flap 6 and the second flap 7 are folded to the maximum angle, there is still an angle between the first flap 6 and the second flap 7.

[0039] Example 3: This example is an improvement made on the basis of Example 2, which solves the problem that part of the liquid will be scraped into the middle of the partition during the reset process of the second flap 7. For details, please refer to Figures 1 to 15 A mesh plate 8 is provided on the outer wall of one end of the first flap 6, and a blocking plate 29 for blocking the mesh plate 8 is provided inside the first flap 6. A limiting groove 30 is provided inside the blocking plate 29, and the movable ball rod 9 is slidably arranged inside the limiting groove 30. A docking piece 12 for squeezing the movable ball rod 9 to slide is fixedly provided inside the sliding groove 11; By arranging docking pieces 12 inside the inclined groove 1101, the smooth groove 1102 and the lifting groove 1103, and there is no docking piece 12 at the docking part of the inclined groove 1101 and the lifting groove 1103, when the movable ball rod 9 slides from the inclined groove 1101 into the smooth groove 1102, the end of the movable ball rod 9 will be resisted by the docking piece 12 and slide onto the docking piece 12. The two ends of the docking piece 12 are arranged at an angle. By utilizing the arrangement of the docking piece 12, the movable ball rod 9 is allowed to slide into the interior of the second flap 7. The end of the second flap 7 is slidably arranged inside the blocking plate 29 opened on the limiting groove 30. The movable ball rod 9 is used to go deep into the second flap 7, thereby allowing the blocking plate 29 to slide inside the second flap 7 and The docking spring 31 is compressed, and in the initial state, the sealing plate 29 will block the mesh plate 8. When the sealing plate 29 slides inside the second flap 7, the mesh plate 8 will be opened, so that when the subsequent second flap 7 slides on the first filter 27, the liquid can pass through the mesh plate 8, further reducing the situation where the liquid on the first filter 27 is scraped into the center position of the partition 5, resulting in a slow separation speed of the liquid and the solid. When the movable ball rod 9 is separated from the docking piece 12, the reset elastic force of the docking spring 31 is used to drive the sealing plate 29 to reset, so that when the subsequent second flap 7 and the first flap 6 are reset to the initial state, the sealing plate 29 blocks the mesh plate 8 to prevent the liquid from flowing into the cleaning below the partition 5 due to cooling crystallization.

[0040] Example 4: This example is an improvement made on the basis of Example 3, which solves the sealing problem of the first flap 6 and the second flap 7 in the initial state. For details, please refer to Figures 1 to 15 The outer wall of the blocking plate 29 is fixedly provided with an extrusion plate 32, and the outer surface of the extrusion plate 32 is sleeved with a docking spring 31. A cavity 33 is opened inside the second flap 7, and the extrusion plate 32 is slidably arranged inside the cavity 33. The side of the cavity 33 is connected with a connecting pipe 34. The first flap 6 and the second flap 7 are respectively provided with a second airbag 36 and a first airbag 35. The first airbag 35 and the second airbag 36 are both connected to the connecting pipe 34; When the blocking plate 29 slides toward the first flap 6 from the inside of the second flap 7, it will simultaneously drive the extrusion plate 32 to slide inside the cavity 33. The cavity 33 is connected to the connecting pipe 34. The sliding of the extrusion plate 32 is used to suck the extrusion plate 32, and then the electric telescopic rod 25 and the pulling wire 26 are sucked, so that the first airbag 35 and the second airbag 36 in the expanded state are reset, making the subsequent folding movement of the first flap 6 and the second flap 7 more convenient. When the first flap 6 and the second flap 7 are reset, the extrusion plate 32 is moved to press the cavity 33. The internal gas is squeezed and the first airbag 35 and the second airbag 36 are gradually expanded. When the first flap 6 and the second flap 7 are restored to their initial states, the expansion of the first airbag 35 and the second airbag 36 is used to reduce the docking gap, thereby preventing liquid from flowing from the gap between the first flap 6 and the second flap 7 to the bottom of the partition 5. It should be noted that the other half of the cavity 33 away from the blocking plate 29 has a larger area and the displacement distance of the squeezing plate 32 is smaller. When the cavity 33 moves, the internal gas can be slightly squeezed and compressed, allowing the squeezing plate 32 to move normally. It should be noted that the cooling crystallization is located in the middle of the partition 5, on the first flap 6 and the second flap 7. When the liquid is located at the partition 5, the drainage pipe provided at the bottom of the storage tank 4 is used to discharge the liquid that has been purified by removing impurities from the bottom of the partition 5. Subsequently, while heating the storage tank 4, a solution that can dissolve the cooling crystallization impurities is added. When the dissolution is completed, it is discharged again through the drainage pipe. It should be noted that the solution of cooling crystallization impurities is an existing technology, and those skilled in the art can select it according to actual needs. A second filter screen 28 is provided in the middle of the partition 5. The second filter screen 28 can separate the cooling crystallization and the liquid, so that the cooling crystallization and the liquid pushed into the middle of the partition 5 by the second flap 7 can be separated through the second filter screen 28 and enter the bottom of the partition 5.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
