Description

Technical Field

[0001] This utility model relates to the field of solid-liquid separation technology, specifically a solid-liquid separation device for chiral lipid reactions. Background Technology

[0002] Chiral esters are a class of ester compounds with chiral centers. During the production of chiral esters, a mixture of solid and liquid is often produced. In order to ensure the purity and quality of the product, it is necessary to effectively separate the solid and liquid. A solid-liquid separation device for chiral ester reaction can efficiently separate the two, thereby obtaining chiral ester products that meet quality standards.

[0003] Existing solid-liquid separation devices for chiral lipid reactions mainly consist of a cylinder cover, cylinder body, filter plate, and cylinder bottom. During solid-liquid separation, the mixture to be separated is first introduced into the cylinder body through the feed inlet. Under the action of pressure or gravity, the liquid permeates through the filter medium to the bottom of the filter plate, while the solid particles are blocked on the filter medium. The separated liquid is discharged through the filtrate outlet at the bottom of the cylinder, and the trapped fixed particles are taken out through the feed port of the cylinder body, thus enabling effective separation of solids and liquids.

[0004] In existing solid-liquid separation devices for chiral lipid reactions, residual moisture in the retained fixed particles is not effectively squeezed out after solid-liquid separation, resulting in high moisture content in the final solid particles, which affects their drying degree. At the same time, the residual moisture means that the solid-liquid separation is not thorough, leading to poor solid-liquid separation effect. Therefore, a solid-liquid separation device for chiral lipid reactions is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve the problems mentioned in the background art, this utility model proposes a solid-liquid separation device for chiral lipid reaction.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A solid-liquid separation device for chiral lipid reactions, comprising a base, an outer cylinder fixedly connected to the base, a filter cylinder rotatably installed inside the outer cylinder, multiple fixing posts fixedly connected to the inner wall of the bottom end of the outer cylinder, the multiple fixing posts cooperating to fix a limiting ring, and the limiting ring sleeved on the outside of the filter cylinder, a toothed ring fixed to the outer surface of the filter cylinder, a mounting frame fixedly connected to the outer wall of the outer cylinder, a motor mounted on the mounting frame, a gear mounted on the output end of the motor, and the gear meshing with the toothed ring, a material inlet opening on the top side of the filter cylinder, two pneumatic cylinders mounted on the base, each pneumatic cylinder having a pneumatic rod mounted on its working end, a support plate fixedly connected to the top of each pneumatic rod, a ring sleeve connected to the support plate located directly above the motor, and a connection between the two support plates. A sleeve is fixedly connected, and a telescopic rod is slidably assembled inside the sleeve. A pressing and sealing cover plate is fixedly connected to the bottom end of the telescopic rod, and the diameter of the pressing and sealing cover plate is the same as the diameter of the feed inlet. When filtering and separating a solid-liquid mixture, the solid-liquid mixture to be separated is first put into the filter cylinder through the feed inlet. Then, a pneumatic cylinder operates, causing the pneumatic rod to drive the support plate and the pressing and sealing cover plate to move vertically downward until the pressing and sealing cover plate moves down to block the feed inlet above the filter cylinder. At this point, the pneumatic cylinder stops operating, and then the motor is started, causing the gear to rotate, which forces the gear ring to rotate. With the cooperation of the limiting ring, the gear drives the filter cylinder to rotate stably. As the filter cylinder rotates, the liquid flows through the filter holes into the cavity formed by the filter cylinder and the outer cylinder, while the solid particles are effectively trapped in the filter cylinder. This structure ensures the high efficiency of solid-liquid separation and greatly improves the separation efficiency.

[0007] Preferably, the sleeve has a groove, and a sliding rod is installed in the groove. One end of the sliding rod is fixed to the top of the telescopic rod, and the other end of the sliding rod is fixed to a lifting block. Fixed plates are fixed to both the upper and lower ends of the sleeve. A lead screw is rotatably mounted on the two fixed plates, and the lead screw passes through the lifting block. A motor is mounted on the upper fixed plate, and the output end of the motor is connected to the top of the lead screw. After solid-liquid separation, to ensure that the fixed particles trapped in the filter cylinder can be effectively squeezed out, the motor is started, causing the lead screw to rotate. With the cooperation of the groove and the sliding rod, the lifting block moves stably downward, which in turn causes the telescopic rod to drive the pressing sealing cover plate to move stably downward. This presses down the fixed particles trapped in the filter cylinder, allowing the residual moisture in the solid particles to flow back into the cavity formed by the filter cylinder and the outer cylinder through the filter holes. This helps to further squeeze out the residual moisture in the solid particles, reducing the internal moisture and resulting in drier solid particles and a more significant solid-liquid separation effect.

[0008] Preferably, the pressing and sealing cover plate has a slot, in which a scraper is inserted. The top of the scraper is fixedly connected to an anti-detachment plate, and a handle is mounted on the anti-detachment plate. When filtering and separating the solid-liquid mixture, the scraper will descend synchronously with the pressing and sealing cover plate. When the pressing and sealing cover plate blocks the material inlet above the filter cylinder, the scraper is in contact with the inner wall of the filter cylinder. As the filter cylinder rotates, the scraper can effectively scrape off the solid particles attached to the inner wall of the filter cylinder. This helps to prevent the accumulation of solid particles on the inner wall of the filter cylinder, thereby maintaining the unobstructed flow of the filter cylinder, reducing the risk of blockage, and improving the filtration effect. The slot and scraper make it easy to remove or replace the scraper from the pressing and sealing cover plate.

[0009] Preferably, a drain pipe is connected to the bottom circumferential surface of the outer cylinder, and a one-way valve is installed on the drain pipe. When using the device, the drain pipe facilitates the discharge of the separated liquid.

[0010] The advantages of this utility model are:

[0011] 1. In the process of filtering and separating solid-liquid mixtures, the present invention first feeds the solid-liquid mixture to be separated into the filter cylinder through the feed inlet. Then, the pneumatic cylinder operates to drive the pneumatic rod to move the support plate and the pressing sealing cover vertically downward until the pressing sealing cover moves down to block the feed inlet above the filter cylinder. At this point, the pneumatic cylinder stops operating, and then the motor is started to make the gear rotate, which forces the gear ring to rotate. With the cooperation of the limit ring, the gear drives the filter cylinder to rotate stably. As the filter cylinder rotates, the liquid flows through the filter holes into the cavity formed by the filter cylinder and the outer cylinder, while the solid particles are effectively trapped in the filter cylinder. This structure ensures the high efficiency of solid-liquid separation and greatly improves the separation efficiency.

[0012] 2. After the solid-liquid separation is completed, in order to ensure that the fixed particles trapped in the filter cylinder can be effectively squeezed out, the motor is started to make the lead screw rotate. With the cooperation of the slide groove and slide rod, the lifting block moves down steadily, which in turn causes the telescopic rod to drive the pressing sealing cover plate to move down steadily. This can press the fixed particles trapped in the filter cylinder, so that the water remaining in the solid particles flows back into the cavity formed by the filter cylinder and the outer cylinder through the filter holes. This helps to squeeze out the water remaining in the solid particles, reduce the water remaining inside, and make the final solid particles drier, and the solid-liquid separation effect more significant.

[0013] 3. In the process of filtering and separating solid-liquid mixtures, the scraper will descend synchronously with the pressing of the sealing cover. When the pressing of the sealing cover blocks the material inlet above the filter cylinder, the scraper is in contact with the inner wall of the filter cylinder. As the filter cylinder rotates, the scraper can effectively scrape off the solid particles attached to the inner wall of the filter cylinder. This helps to prevent the accumulation of solid particles on the inner wall of the filter cylinder, thereby maintaining the unobstructed flow of the filter cylinder, reducing the risk of clogging, and improving the filtration effect.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] Please see Figure 1-5 As shown, a solid-liquid separation device for chiral lipid reactions includes a base 1, an outer cylinder 2 fixedly connected to the base 1, a filter cylinder 3 rotatably mounted inside the outer cylinder 2, multiple fixing posts 4 fixedly connected to the inner wall of the bottom end of the outer cylinder 2, and a limiting ring 5 fixedly connected to the multiple fixing posts 4, with the limiting ring 5 sleeved on the outside of the filter cylinder 3. A toothed ring 6 is fixedly fixed to the outer surface of the filter cylinder 3, and a mounting frame 7 is fixedly connected to the outer wall of the outer cylinder 2. A motor 8 is mounted on the mounting frame 7, and a gear 9 is mounted on the output end of the motor 8, with the gear 9 meshing with the toothed ring 6. A feed port 10 is opened on the top side of the filter cylinder 3. Two pneumatic cylinders 11 are mounted on the base 1, and each of the two pneumatic cylinders 11 is equipped with a pneumatic rod 12. A support plate 13 is fixedly connected to the top end of each of the two pneumatic rods 12. The device is used for solid-liquid mixing. When the material is filtered and separated, the solid-liquid mixture to be separated is first fed into the filter cylinder 3 through the feed port 10. Then, the pneumatic cylinder 11 operates, causing the pneumatic rod 12 to drive the support plate 13 and the pressing sealing cover plate 17 to move vertically downwards until the pressing sealing cover plate 17 moves down to block the feed port 10 above the filter cylinder 3. At this point, the pneumatic cylinder 11 stops operating. Then, the motor 8 is started, causing the gear 9 to rotate, which forces the gear ring 6 to rotate. With the cooperation of the limiting ring 5, the gear 9 drives the filter cylinder 3 to rotate stably. As the filter cylinder 3 rotates, the liquid flows through the filter holes into the cavity formed by the filter cylinder 3 and the outer cylinder 2, while the solid particles are effectively trapped inside the filter cylinder 3. This structure ensures the high efficiency of solid-liquid separation and greatly improves the separation efficiency.

[0023] A ring 14 is connected to a support plate 13 located directly above the motor 8. A sleeve 15 is fixed between the two support plates 13. A telescopic rod 16 is slidably fitted inside the sleeve 15. A pressing sealing cover 17 is fixed to the bottom end of the telescopic rod 16, and the diameter of the pressing sealing cover 17 is the same as the diameter of the feed port 10. A sliding groove 18 is opened on the sleeve 15, and a sliding rod 19 is installed in the sliding groove 18. One end of the sliding rod 19 is fixed to the top end of the telescopic rod 16, and the other end of the sliding rod 19 is fixed to a lifting block 20. Fixed plates 21 are fixed to both the upper and lower ends of the sleeve 15. A lead screw 22 is rotatably installed on the two fixed plates 21, and the lead screw 22 passes through the lifting block 20. A motor 23 is installed on the upper fixed plate 21. The output end of motor 23 is connected to the top of lead screw 22. After solid-liquid separation is completed, in order to ensure that the fixed particles trapped in the filter cylinder 3 can be effectively squeezed out, motor 23 is started, causing lead screw 22 to rotate. With the cooperation of slide groove 18 and slide rod 19, lifting block 20 moves down steadily, which in turn causes telescopic rod 16 to drive the pressing sealing cover 17 to move down steadily. This can press the fixed particles trapped in the filter cylinder 3, so that the residual water in the solid particles flows back into the cavity formed by filter cylinder 3 and outer cylinder 2 through filter holes. This helps to further squeeze out the residual water in the solid particles, reduce the residual water inside, and make the final solid particles drier, resulting in a more significant solid-liquid separation effect.

[0024] Please see Figure 3 As shown, a slot 24 is provided on the press-sealing cover plate 17, and a scraper 25 is inserted into the slot 24. An anti-detachment plate 26 is fixed to the top of the scraper 25, and a handle 27 is mounted on the anti-detachment plate 26. When filtering and separating solid-liquid mixtures, the scraper 25 will descend synchronously with the press-sealing cover plate 17. When the press-sealing cover plate 17 blocks the material port 10 above the filter cylinder 3, the scraper 25 is in contact with the inner wall of the filter cylinder 3. As the filter cylinder 3 rotates, the scraper 25 can effectively scrape off the solid particles attached to the inner wall of the filter cylinder 3. This helps to prevent the accumulation of solid particles on the inner wall of the filter cylinder 3, thereby maintaining the unobstructed flow of the filter cylinder 3, reducing the risk of blockage, and improving the filtration effect. The slot 24 and the scraper 25 make it easy to remove or replace the scraper 25 from the press-sealing cover plate 17.

[0025] Please see Figure 1 As shown, a drain pipe 28 is connected to the bottom circumferential surface of the outer cylinder 2, and a one-way valve is installed on the drain pipe 28; when using the device, the drain pipe 28 facilitates the discharge of the separated liquid.

[0026] Working Principle: Existing solid-liquid separation devices for chiral lipid reactions often fail to effectively remove residual moisture from the retained solid particles after solid-liquid separation. This results in high moisture content in the final solid particles, affecting their drying properties. Furthermore, the residual moisture indicates incomplete solid-liquid separation, leading to poor separation efficiency. Therefore, this invention proposes a solid-liquid separation device for chiral lipid reactions. When filtering a solid-liquid mixture, the mixture is first fed into the filter cylinder 3 through the feed inlet 10. Then, the pneumatic cylinder 11 operates, causing the pneumatic rod 12 to drive the support plate 13 and the pressing sealing cover 17 vertically downwards until the pressing sealing cover 17 seals the feed inlet 10 above the filter cylinder 3. At this point, the pneumatic cylinder 11 stops operating, and the motor 8 is started, causing the gear 9 to rotate. This forces the gear ring 6 to rotate, and with the cooperation of the limiting ring 5, the gear 9 drives the filter cylinder 3. The filter cylinder 3 rotates steadily, allowing liquid to flow through the filter holes into the cavity formed by the filter cylinder 3 and the outer cylinder 2. Solid particles are effectively trapped inside the filter cylinder 3. This structure ensures high efficiency in solid-liquid separation and greatly improves separation efficiency. After solid-liquid separation, in order to ensure that the fixed particles trapped inside the filter cylinder 3 can be effectively squeezed out, the motor 23 is started, causing the lead screw 22 to rotate. With the cooperation of the slide groove 18 and the slide rod 19, the lifting block 20 moves down steadily, which in turn causes the telescopic rod 16 to drive the pressing sealing cover 17 to move down steadily. This allows the fixed particles trapped inside the filter cylinder 3 to be pressed, causing the residual water in the solid particles to flow back into the cavity formed by the filter cylinder 3 and the outer cylinder 2 through the filter holes. This helps to further squeeze out the residual water in the solid particles, reducing the residual water inside, making the final solid particles drier, and the solid-liquid separation effect more significant.

[0027] When filtering and separating solid-liquid mixtures, the scraper 25 descends synchronously with the pressing sealing cover 17. When the pressing sealing cover 17 blocks the material inlet 10 above the filter cylinder 3, the scraper 25 is in contact with the inner wall of the filter cylinder 3. As the filter cylinder 3 rotates, the scraper 25 can effectively scrape off the solid particles attached to the inner wall of the filter cylinder 3. This helps to prevent the accumulation of solid particles on the inner wall of the filter cylinder 3, thereby maintaining the unobstructed flow of the filter cylinder 3, reducing the risk of blockage, and improving the filtration effect. The slot 24 and the scraper 25 make it easy to remove or replace the scraper 25 from the pressing sealing cover 17.
