[0021] 1. The triacetin purification processing device utilizes the first turning plate and the second turning plate arranged on the blocking plate. When the first turning plate and the second turning plate are kept in a horizontal state, the passageway on the first filter screen is blocked. When the first turning plate and the second turning plate are folded, the passageway is opened, realizing solid-liquid separation. At the same time, the movement of the second turning plate scrapes the crystalline impurities on the first filter screen, improving the flow rate of the liquid.

[0022] 2. The triacetin purification processing device utilizes the fact that the movement speed of the first turning plate and the second turning plate when they are folded is higher than the movement speed when the second turning plate and the second turning plate are reset. When the second turning plate scrapes the crystalline impurities, it effectively avoids scraping a large amount of liquid to the middle part of the blocking plate, which leads to a low liquid separation rate in the subsequent middle part.

[0023] 3. The triacetin purification processing device utilizes the arrangement of the first air bag and the second air bag. When the first turning plate and the second turning plate are kept in a horizontal state, the expansion of the first air bag and the second air bag reduces the connecting gap, thereby improving the blocking performance of the first turning plate and the second turning plate.

[0041] Embodiment one, please refer to Figures 1 to 15 A device for purifying triacetin, comprising a cooling tank 1, wherein the inside of the cooling tank 1 is provided with a sliding rail 2, the inside of the sliding rail 2 is slidably provided with a sliding block 3, the outer wall of the sliding block 3 is fixedly connected with a storage tank 4, and the inside of the storage tank 4 is fixedly connected with a partition plate 5; further comprising:

[0042] a first flap 6 rotatably installed in the inside of the partition plate 5, wherein the side of the first flap 6 is movably connected with a second flap 7, the inside of the second flap 7 is slidably provided with a movable ball rod 9, and the bottom of the first flap 6 is provided with a first filter screen 27 for filtering liquid;

[0043] a sliding groove 11 formed in the inside of the partition plate 5, wherein the sliding groove 11 comprises a lifting groove 1103, the end of the movable ball rod 9 is slidably arranged in the inside of the lifting groove 1103, and the outside of the movable ball rod 9 is sleeved with a positioning rod 10;

[0044] a rotating disc 13 rotatably installed in the inside of the partition plate 5, wherein the rotating disc 13 is provided with a connecting groove 14 for slidably connecting the positioning rod 10, and the bottom of the rotating disc 13 is provided with a driving part for driving the first flap 6 and the second flap 7 to fold;

[0045] The driving part comprises a rotating shaft 17 fixedly connected to the outer wall of the rotating disc 13, the end of the rotating shaft 17 is fixedly connected with a connecting gear 18, the side of the connecting gear 18 is engaged with a connecting rack 19, the inside of the connecting rack 19 is slidably provided with a positioning frame 20, the positioning frame 20 is fixedly connected between the sliding block 3, the end of the connecting rack 19 is fixedly connected with a push-pull rod 21, the inside of the sliding rail 2 is provided with a driving groove 22 for limiting the movement of the push-pull rod 21, the driving groove 22 comprises a smooth part 2201, an inclined part 2202 and a reset part 2203 which are communicated, the path length of the inclined part 2202 is smaller than that of the reset part 2203, the middle of the partition plate 5 is provided with a second filter screen 28, and the outer wall of the sliding rail 2 is fixedly provided with a pulling wire 26;

[0046] Firstly, the lifting equipment is used to control the movement of the sliding rail 2, and the storage tank 4 arranged on the sliding rail 2 is immersed into the cooling tank 1, so that the liquid in the storage tank 4 is cooled and crystallized, and the impurities in the liquid are removed. It should be noted that the lifting equipment for controlling the sliding rail 2 can be a hydraulic rod, and the person skilled in the art can select according to the actual requirement. When the crystallization temperature is reached and the liquid in the storage tank 4 is also crystallized, the pulling wire 26 arranged in the sliding rail 2 is controlled to pull the pulling wire 26, so that the sliding block 3 drives the storage tank 4 to slide in the inside of the cooling tank 1. The reciprocating movement of the storage tank 4 is used to move the liquid in the inside of the storage tank 4, so as to facilitate the subsequent filtration and separation of the liquid and the crystal. It should be noted that the pulling of the pulling wire 26 can be a winding disc, which is prior art, and the person skilled in the art can select according to the actual requirement.

[0047] When the sliding block 3 drives the storage tank 4 to slide in the inside of the sliding rail 2, the connecting gear 18 will slide in the inside of the sliding rail 2, and the positioning frame 20 is fixedly arranged on the sliding block 3. 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 engagement. When the connecting gear 18 and the connecting rack 19 slide in the inside of the sliding rail 2 with the sliding block 3, the push-pull rod 21 arranged on the end of the connecting rack 19 will slide in the inside of the driving groove 22. When the push-pull rod 21 slides from the smooth part 2201 into the inside of the inclined part 2202, the connecting rack 19 slides into the inside of the sliding rail 2 at this time, so that the connecting rack 19 drives the connecting gear 18 to rotate clockwise. When the connecting gear 18 rotates, it will drive the rotating shaft 17 and the rotating disc 13 to rotate in the inside of the partition plate 5. The rotating disc 13 is provided with a connecting groove 14, and the positioning rod 10 is slidably arranged in the inside of the connecting groove 14. The rotation of the rotating disc 13 is used to slide the positioning rod 10 in the inside of the connecting groove 14. The inside of the positioning rod 10 is provided with a movable ball rod 9, so that the positioning rod 10 drives the movable ball rod 9 to slide in the inside of the lifting groove 1103 in the sliding groove 11.

[0048] One end of the movable ball rod 9 is slidingly arranged in the interior of the second flap 7, so that when the movable ball rod 9 slides in the lifting groove 1103, the second flap 7 is driven to move, the second flap 7 is slidingly connected with the partition plate 5, and the second flap 7 is rotatably connected with the first flap 6, the first flap 6 is rotatably connected with the partition plate 5 through a rotating shaft, and a torsional spring is arranged at the rotating shaft between the first flap 6 and the second flap 7, so that the first flap 6 and the second flap 7 have a folding tendency under no external force, and when the movable ball rod 9 drives the second flap 7 to move, the first flap 6 and the second flap 7 are folded to form an inverted V-shaped opening, so as to open the passage on the first filter screen 27, and the continuous movement of the second flap 7 driven by the movable ball rod 9 is used to move the second flap 7 on the surface of the first filter screen 27, so as to scrape the crystalline impurities attached to the first filter screen 27, thereby avoiding the situation that a large amount of crystalline impurities accumulated on the first filter screen 27 causes slow liquid filtering effect;

[0049] The first flap 6 and the second flap 7 are arranged to block the passage on the first filter screen 27 when the first flap 6 and the second flap 7 are kept in a horizontal state, and after the crystallization of the liquid impurities is completed, the first flap 6 and the second flap 7 are used to open the passage and gradually approach each other to scrape the crystalline impurities on the first filter screen 27, thereby improving the liquid filtering rate, and when the push-pull rod 21 slides from the inclined portion 2202 into the reset portion 2203, the second flap 7 is reset to move, and the inclined portion 2202 and the reset portion 2203 are arranged to make the second flap 7 reciprocate, thereby achieving the effect of reciprocating scraping of the first filter screen 27, and because the path of the inclined portion 2202 is smaller than that of the reset portion 2203, the inclined portion 2202 takes a longer time to reset to the reset portion 2203, thereby making the second flap 7 fold and approach the first flap 6 at a fast speed and reset at a slow speed.

[0050] It should be noted that when the movable ball rod 9 slides in the lifting groove 1103, the lifting groove 1103 is divided into a vertical groove and a horizontal groove, and at this time, the movable ball rod 9 only slides in the horizontal groove of the lifting groove 1103.

[0051] As an optional solution of the driving part of the application, the driving part comprises a gear disc 23 fixedly connected to the outer wall of the rotating disc 13, the gear disc 23 is externally meshingly connected with a driving rack 24, the end of the driving rack 24 is provided with an electric telescopic rod 25, and the electric telescopic rod 25 is fixedly connected with the partition plate 5.

[0052] When the sliding block 3 drives the storage tank 4 to slide inside the slide rail 2, by controlling the electric telescopic rod 25 arranged at the bottom of the partition plate 5, the extension and retraction movement of the electric telescopic rod 25 is utilized to drive the driving rack 24 to reciprocate on the gear disc 23, thereby driving the rotating disc 13 to rotate forward and backward, and by the forward and backward rotation of the rotating disc 13, the opening of the passage on the pulling wire 26 is realized, and by the movement of the second flap 7 on the first filter screen 27, the crystalline impurities on the first filter screen 27 are scraped, thereby improving the filtering effect of the liquid. It should be noted that the driving speed of the driving rack 24 driving the gear disc 23 clockwise is faster than the driving speed of the gear disc 23 counterclockwise, thereby making the folding speed of the second flap 7 and the first flap 6 faster and the resetting speed slower.

[0053] In the embodiment, the problem that the filtering speed cannot be quickly improved by scraping of the second flap when there are many crystalline impurities on the first filter screen 27 is solved, and the specific solution is shown in Figures 1 to 15 The sliding groove 11 further comprises an inclined groove 1101 and a smooth groove 1102, the inclined groove 1101 and the smooth groove 1102 are communicated, the smooth groove 1102 and the lifting groove 1103 are communicated, the end of the lifting groove 1103 is provided with a limiting block 15, the bottom of the limiting block 15 is fixedly connected with a resetting spring 16, the limiting block 15 is slidingly arranged in the partition plate 5, the positioning rod 10 comprises a positioning sleeve rod 1001 sleeved outside the movable ball rod 9, a sleeve 1003 is sleeved outside the positioning sleeve rod 1001, a telescopic spring 1002 is arranged between the positioning sleeve rod 1001 and the sleeve 1003, and a protrusion for stably sliding in the connecting groove 14 is arranged on the sleeve 1003;

[0054] When the rotating disc 13 rotates, the positioning rod 10 will rotate in the connecting groove 14, the protrusion on the sleeve 1003 is embedded in the groove arranged on the connecting groove 14, so that the sleeve 1003 can only slide left and right on the connecting groove 14, and the sliding groove 11 is further provided with the inclined groove 1101 and the smooth groove 1102, when the rotating disc 13 rotates clockwise, the movable ball rod 9 is limited by the limiting block 15, and will first slide into the interior of the inclined groove 1101, and then will slide from the interior of the inclined groove 1101 to the interior of the smooth groove 1102 along with the continuous rotation of the rotating disc 13;

[0055] At this time, the movable ball rod 9 will drive the second flap 7 to fold towards the first flap 6, which will lift the second flap 7 upwards, and then separate the second flap 7 from the first filter screen 27 during the process of the second flap 7 approaching the first flap 6. At the same time, when the movable ball rod 9 slides from the inclined groove 1101 to the smooth groove 1102, the positioning sleeve rod 1001 will slide in the sleeve 1003 and press the extension spring 1002. As the rotating disc 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 with the vertical groove of the lifting groove 1103, the reset spring force of the extension spring 1002 drives the positioning sleeve rod 1001 to slide in the sleeve 1003, and finally the movable ball rod 9 slides in the horizontal groove of the sleeve 1003, and the second flap 7 is attached to the surface of the first filter screen 27.

[0056] As the rotating disc 13 reverses, the positioning rod 10 drives the movable ball rod 9 to reset in the sleeve 1003, and the second flap 7 slides on the surface of the first filter screen 27. By sliding the second flap 7 on the first filter screen 27, the crystalline impurities on the first filter screen 27 are pushed into the groove in the middle of the baffle 5, achieving the effect of scraping off the crystalline impurities on the first filter screen 27. Because the speed of the second flap 7 during the reset process is slower than that during the folding process of the second flap 7 and the first flap 6, the slower reset movement of the second flap 7 can reduce the possibility of scraping liquid to the center of the baffle 5 during the scraping process of the second flap 7 on the first filter screen 27. When there is less liquid left on the first filter screen 27, the liquid is scraped to the center of the baffle 5.

[0057] 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 press the limiting block 15, and the limiting block 15 will move while compressing the reset spring 16, and finally the movable ball rod 9 will move to the top end of the limiting 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.

[0058] In this embodiment, the second flap 7 is improved based on the second flap 7 in the second embodiment, which solves the problem of scraping some liquid into the middle of the baffle during the reset process of the second flap 7. For details, please refer to Figures 1 to 15 The first flap 6 has a mesh plate 8 at one end of the outer wall, and the first flap 6 has a blocking plate 29 inside to block the mesh plate 8. The inside of the blocking plate 29 is provided with a limiting groove 30, and the movable ball rod 9 is slidingly arranged in the limiting groove 30. The sliding groove 11 is fixedly provided with a pressing plate 12 that presses the movable ball rod 9 to slide.

[0059] By setting the abutting piece 12 inside the inclined groove 1101, the smooth groove 1102 and the lifting groove 1103, and not setting the abutting piece 12 at the part where the inclined groove 1101 and the lifting groove 1103 abut, 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 abutting piece 12 and slide into the abutting piece 12. The two ends of the abutting piece 12 are inclined, and the abutting piece 12 is used to make the movable ball rod 9 slide into the second flap 7. The end of the second flap 7 is slidingly arranged inside the blocking plate 29 arranged on the limiting groove 30. By making the movable ball rod 9 slide into the second flap 7, the blocking plate 29 is made to slide in the second flap 7 and compress the abutting spring 31. In the initial state, the blocking plate 29 blocks the mesh plate 8. When the blocking plate 29 slides in the second flap 7, the mesh plate 8 is opened, so that when the second flap 7 slides on the first filter screen 27, the liquid can pass through the mesh plate 8, further reducing the situation that the liquid on the first filter screen 27 is scraped into the center of the partition plate 5, causing the liquid and solid to separate slowly. When the movable ball rod 9 is separated from the abutting piece 12, the restoring force of the abutting spring 31 is used to reset the blocking plate 29, so that the second flap 7 and the first flap 6 are reset to the initial state, the blocking plate 29 blocks the mesh plate 8, and the liquid is prevented from flowing into the cleaning part below the partition plate 5 to cool and crystallize.

[0060] In example four, the first flap 6 and the second flap 7 are improved based on example three to solve the problem of the initial state of the sealing. Please refer to Figures 1 to 15 The outer wall of the blocking plate 29 is fixedly provided with an extrusion plate 32, the extrusion plate 32 is externally sleeved with the abutting spring 31, the second flap 7 is internally provided with a cavity 33, the extrusion plate 32 is slidingly arranged in the cavity 33, the cavity 33 is communicated with a communication pipe 34, the first flap 6 and the second flap 7 are respectively provided with a second air bag 36 and a first air bag 35, and the first air bag 35 and the second air bag 36 are communicated with the communication pipe 34.

[0061] When the blocking plate 29 slides to the first flap 6 inside the second flap 7, the extrusion plate 32 will slide inside the cavity 33, the cavity 33 is communicated with the communication pipe 34, the cavity 33 is pumped by the sliding of the extrusion plate 32, and then the first air bag 35 and the second air bag 36 are pumped, so that the first air bag 35 and the second air bag 36 in the inflated state are reset, and the folding movement of the subsequent first flap 6 and the second flap 7 is more convenient, when the subsequent first flap 6 and the second flap 7 are reset, the extrusion plate 32 moves, the gas in the cavity 33 is extruded, and the first air bag 35 and the second air bag 36 are gradually inflated, so that the first flap 6 and the second flap 7 are reset to the initial state, the inflation of the first air bag 35 and the second air bag 36 is used to reduce the butt gap, avoid the liquid from flowing into the bottom of the partition plate 5 from the gap between the first flap 6 and the second flap 7, it should be noted that the other half of the cavity 33 far away from the blocking plate 29 has a larger area, and the displacement distance of the extrusion plate 32 is smaller, when the cavity 33 moves, the internal gas can be slightly extruded and compressed, so that the extrusion plate 32 can move normally;

[0062] It should be noted that the cooling crystallization is located in the middle of the partition plate 5, the first flap 6 and the second flap 7, and the liquid is located in the partition plate 5, the liquid removed from the bottom of the partition plate 5 is discharged by the discharge pipe arranged at the bottom of the storage tank 4, and then the storage tank 4 is heated and the solution that can dissolve the cooling crystallization impurity is added, after the solution is dissolved, it is discharged again through the discharge pipe, it should be noted that the solution of the cooling crystallization impurity is a prior art, and those skilled in the art can select according to actual needs, the middle of the partition plate 5 is provided with a second filter screen 28, 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 plate 5 by the second flap 7 can be separated and enter the bottom of the partition plate 5 through the second filter screen 28.
