Description

Technical Field

[0001] This invention relates to the field of crystallization equipment technology, specifically to a crystallization device used in the enzymatic preparation of calcium gluconate. Background Technology

[0002] Calcium gluconate is mainly used as a calcium fortifier and nutrient in food, as well as a buffer, solidifying agent, and chelating agent. In chemistry, when a hot saturated solution is cooled, the solute precipitates out in the form of crystals; this process is called crystallization.

[0003] The crystallization process of a solution requires a certain amount of time. Only when the solution reaches a certain surface energy nucleation barrier within a certain time can crystal nuclei be formed. Furthermore, during nucleation, crystal nuclei will first form on the inner wall of the container. This is because the container wall effectively lowers the surface energy nucleation barrier, so crystal nuclei are preferentially formed at these non-uniform locations, and then gradually form inside the solution.

[0004] Therefore, the crystallization process takes a long time. When crystals form on the inner wall of the container, they adhere to the inner wall, making subsequent cleaning difficult. Moreover, existing crystallization equipment is generally in the form of a tank. After crystals form on the inner wall, they adhere to the tank. Then, after a fixed period of time, the tank is opened and the crystals on the inner wall are cleaned. This method is inefficient because crystals preferentially form on the inner wall of the tank. As crystals form, the mass of the solute decreases, which causes the potential barrier for nucleation at the solution surface in the middle of the tank and far from the inner wall to gradually decrease. Therefore, the crystallization time is longer, which reduces the overall crystallization efficiency.

[0005] Based on this, the present invention designs a crystallization device for use in the enzymatic preparation of calcium gluconate to solve the above problems. Summary of the Invention

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. Multiple insert plates are placed inside the solution, which lowers the nucleation barrier at the solution surface due to the insert plates, the inner wall of the tank, and the outer wall of the cylinder. As a result, crystal nuclei can form in these non-uniform locations of the melt, and local nucleation can occur even at very low cooling temperatures. This accelerates the crystallization efficiency. Furthermore, regardless of whether the solute quality is high or low, it creates preferential nucleation barrier conditions for the solute, thereby reducing the time required for autonomous nucleation, reducing waiting time, and improving nucleation efficiency.

[0019] 2. After the first cylinder extends and retracts multiple times, it indicates that the crystals on the inner wall of the tank, the outer wall of the cylinder, and the ends of multiple insert plates have been scraped off multiple times. By continuously scraping off the crystals, it is possible to prevent crystal adhesion, improve the subsequent separation effect of crystals, and crush larger crystals by pressing them down.

[0020] 3. The air inside the T-shaped component is intermittently blown outward from the inside of the filter frame through the air blowing hole, thereby blowing away the crystals attached to the outside of the filter frame and preventing blockage. The rotating assembly drives the second gear to rotate intermittently. During the rotation of the second gear, the baffle plate rotates around the T-shaped component. When the baffle plate rotates, it drives the cleaning plate to rotate. During the rotation of the cleaning plate, it can also scrape off the crystals on the outside of the filter frame, further preventing blockage and affecting the filtration of the filter frame.

[0035] Please see Figure 1-12 This invention provides a technical solution: a crystallization device applied in the enzymatic preparation of calcium gluconate, comprising a tank 1, a liquid inlet 2 provided on the side wall of the tank 1, a cylinder 3 provided inside the tank 1, a cleaning rod 4 provided between the cylinder 3 and the inner wall of the tank 1, the cleaning rod 4 being used to clean the inner wall of the tank 1 and the outer wall of the cylinder 3, a plurality of insert plates 5 being slidably connected to the bottom wall of the inner wall of the cylinder 3; each insert plate 5 being fixedly connected to a first spring 10 for resetting, each insert plate 5 having a plurality of extension edges at its end, the extension edges being slidably connected to the cylinder 3, a first cylinder 38 being fixedly connected between the cleaning rod 4 and the top wall of the inner wall of the tank 1, the cylinder 3 being fixedly connected to the rod of the first cylinder 38, and a drive group provided inside the tank 1, the drive group being used to drive the plurality of insert plates 5 to slide along the cylinder 3 when the cleaning rod 4 descends and ascends.

[0036] When the above scheme is put into actual use, the solution is added to the inside of the tank 1 through the liquid inlet 2, and the solution is located between the inner wall of the tank 1 and the outer wall of the cylinder 3. The highest liquid level of the solution cannot exceed the top of the insert plate 5. Then, cooling is performed. Since the insert plate 5 is located between the inner wall of the tank 1 and the outer wall of the cylinder 3, and the solution is also located inside the solution at this position, the insert plate 5, the inner wall of the tank 1 and the outer wall of the cylinder 3 will lower the nucleation barrier on the solution surface. Therefore, the melt will form crystal nuclei at these non-uniform locations, and local nucleation can also occur even at a very low cooling temperature, which will accelerate the crystallization efficiency.

[0037] During the cooling process, the solution preferentially crystallizes on the insert plates 5, the inner wall of the tank 1, and the outer wall of the cylinder 3, and the crystallization efficiency is faster. During the crystallization process, the first cylinder 38 is intermittently activated, causing the first cylinder 38 to extend and retract intermittently. When the first cylinder 38 extends, it drives the cleaning rod 4 to descend. When the first cylinder 38 extends, the drive assembly drives several insert plates 5 to slide along the cylinder 3 towards the middle and compress the first spring 10. When the insert plates 5 move to their limit position, the ends of the insert plates 5 will move to the same position as the outer wall of the cylinder 3. At this point, the cylinder 3 becomes a sealed cylinder, and the cleaning rod 4 is shaped like two rings, which can scrape off the crystals on the inner wall of the tank 1, the outer wall of the cylinder 3, and the ends of the insert plates 5 during the descent. Then, the first cylinder 38 shortens to raise the cleaning rod 4 to the initial height, and then the first spring 10 pushes the insert plates 5 to reset. At this time, the insert plates 5 will re-enter the solution. At this time, the nucleation barrier of the solution is lowered, so that the solution crystallizes again on the inner wall of the tank 1, the outer wall of the cylinder 3, and the ends of the multiple insert plates 5.

[0038] After the first cylinder 38 extends and retracts multiple times, it indicates that the crystals on the inner wall of the tank 1, the outer wall of the cylinder 3, and the ends of the multiple insert plates 5 have been scraped off multiple times. By continuously scraping off the crystals, it is possible to prevent crystal adhesion and improve the subsequent separation effect of the crystals. After all the crystals have been scraped off, if there are large crystals accumulating, the cleaning rod 4 can also press down and break the larger crystals when it descends. At this time, the crystallization time of the solution is also extended, and the mass of the solute is reduced. The traditional method is to allow the solution to crystallize automatically over a long period of time. However, by inserting the insert plates 5 into the solution, regardless of whether the mass of the solute is high or low, a preferential nucleation barrier condition is created for the solute, thereby reducing the time for the solute to nucleate autonomously, reducing the waiting time, and improving the nucleation efficiency.

[0039] As a further embodiment of the present invention, the drive assembly includes a second cylinder 6, and a toothed assembly 7 is slidably connected to the bottom end of the second cylinder 6; the toothed assembly 7 is fixedly connected to a second spring 11 for resetting it; the toothed assembly 7 is formed by a plurality of rack rods fixedly connected together, the number of rack rods corresponding one-to-one with the number of insert plates 5; a first gear 8 corresponding one-to-one with the number of insert plates 5 is provided below the toothed assembly 7; the first gear 8 is rotatably connected to the inner wall of the cylinder 3; the shaft of the first gear 8 is wound with a pull rope 9; the other end of the pull rope 9 is fixedly connected to the insert plate 5 located on one side of it.

[0040] When the aforementioned drive unit is working, when the first cylinder 38 extends and drives the cleaning rod 4 to descend, the second cylinder 6 starts simultaneously with the first cylinder 38. At this time, the cleaning rod 4 and the toothed assembly 7 descend synchronously. However, the initial position of the toothed assembly 7 is lower than that of the cleaning rod 4. As the toothed assembly 7 descends, it meshes with several first gears 8 below and drives the first gears 8 to rotate. During the rotation of the first gears 8, the pull rope 9 is wound up. When the pull rope 9 is wound up, it pulls the insert plate 5 to slide along the cylinder 3 and compresses the first spring 10. When the first spring 10 is compressed to its limit, the end of the insert plate 5 will be at the same level as the outer wall of the cylinder 3, thereby sealing the cylinder 3. Then, when the cleaning rod 4 descends, it will not come into contact with the insert plate 5. When the first spring 10 is compressed to its limit, the bottom end of the toothed assembly 7 will contact the inner bottom wall of the cylinder 3. Then, during the descent of the cleaning rod 4, the end of the second cylinder 6 will slide down inside the toothed assembly 7 and compress the second spring 11.

[0041] When the second cylinder 6 and the first cylinder 38 shorten synchronously, the cleaning rod 4 will rise. However, the toothed assembly 7 will not rise until the elasticity of the second spring 11 is reset, so the insert plate 5 will not extend outward, thus avoiding the cleaning rod 4 from colliding with the insert plate 5.

[0042] As a further embodiment of the present invention, a bottom plate 12 is provided at the bottom end of the tank body 1, and two closing groups are provided on the outer side of the bottom plate 12. The closing groups are used to drive the bottom plate 12 to close with the tank body 1. Two liquid outlet pipes 13 are fixedly connected to the bottom plate 12, and a liquid discharge group is provided inside the two liquid outlet pipes 13.

[0043] The drainage assembly includes a filter frame 14 with a T-shaped cross-section. The filter frame 14 is slidably connected to the inner wall of the outlet pipe 13. A third cylinder 28 is fixedly connected between the bottom of the filter frame 14 and the outlet pipe 13. The bottom of the filter frame 14 is in contact with the inner wall of the outlet pipe 13. Filter holes are provided above the bottom of the filter frame 14. A T-shaped component 15 is fixedly connected to the top of the filter frame 14. The T-shaped component 15 is hollow in the middle and has several air blowing holes 16. A drainage pipe 39 with a T-shaped cross-section is fixedly connected to the filter frame 14. The drainage pipe 39 is located inside the T-shaped component 15, and the top of the drainage pipe 39 is lower than the top of the filter frame 14. A baffle plate 17 is rotatably connected to the top of the T-shaped part 15. The diameter of the baffle plate 17 is the same as the diameter of the liquid outlet pipe 13. A second gear 19 is fixedly connected to the top of the baffle plate 17. An air inlet pipe 18 is fixedly connected to the top of the T-shaped part 15. The air inlet pipe 18 passes through the baffle plate 17 and the second gear 19. Several cleaning plates 20 are fixedly connected to the bottom of the baffle plate 17. The cleaning plates 20 are in contact with the outer wall of the filter frame 14. An exhaust pipe 21 is slidably connected to the outside of the air inlet pipe 18. The end of the exhaust pipe 21 is located inside the cylinder 3. A compression box 22 is fixedly connected to the exhaust pipe 21. A pressure rod 23 is provided above the compression box 22. The pressure rod 23 is fixedly connected to the telescopic end of the second cylinder 6.

[0044] An opening and closing assembly is provided on one side of the compression box 22, which is used to connect the compression box 22 with the outside when the pressure rod 23 rises. A rotating assembly is provided on one side of the second gear 19, which is used to drive the second gear 19 to rotate.

[0045] As a further embodiment of the present invention, the opening and closing assembly includes a sealing plate 24, which is slidably connected to the compression box 22; the sealing plate 24 is fixedly connected to a third spring 25 for resetting it; the top and bottom ends of the sealing plate 24 are both provided with inclined surfaces; the top end of the pressure rod 23 is rotatably connected to a paddle 26; and the rotating shaft of the paddle 26 is sleeved with a torsion spring 27.

[0046] When the above scheme is working, after the solution crystallizes for a certain period of time, it is necessary to separate the crystals from the solution. At this time, the third cylinder 28 is activated. The third cylinder 28 extends and drives the filter frame 14 to slide and rise inside the liquid outlet pipe 13. When the third cylinder 28 extends to its limit, the bottom of the filter frame 14 is flush with the top of the liquid outlet pipe 13. At this time, the solution located between the tank body 1 and the cylinder 3 will flow into the bottom filter frame 14, while the crystals will be filtered to the outside of the filter frame 14. After the solution flows to the inside of the filter frame 14, it will be outside the drain pipe 39, and then discharged to the outside of the tank body 1 through the drain pipe 39. The outside of the tank body 1 is equipped with a device for collecting the solution.

[0047] There are also a lot of crystals inside the solution, which may cause blockage when the solution is filtered by the filter frame 14. Therefore, when the solution is filtered by the filter frame 14, the second cylinder 6 needs to be activated to make the second cylinder 6 continue to extend intermittently. When the second cylinder 6 extends, it will drive the tooth assembly 7 and the pressure rod 23 to descend. When the bottom end of the tooth assembly 7 contacts the inner bottom wall of the cylinder 3, the end of the second cylinder 6 will slide along the tooth assembly 7 and compress the second spring 11. When the second spring 11 is compressed, the pressure rod 23 will descend to the position of contacting the compression box 22. As the second spring 11 is continuously compressed, the pressure rod 23 will also slide down along the inner wall of the compression box 22.

[0048] As the pressure rod 23 slides down along the inner wall of the compression box 22, the sealing plate 24 seals the compression box 22. During this process, the pressure rod 23 discharges the air inside the compression box 22 to the exhaust pipe 21, while the exhaust pipe 21 discharges the air into the T-shaped part 15 through the air inlet pipe 18. The air inside the T-shaped part 15 is intermittently blown outward from the inside of the filter frame 14 through the air blowing hole 16, thereby blowing away the crystals attached to the outside of the filter frame 14 and preventing blockage. The rotating assembly drives the second gear 19 to rotate intermittently. During the rotation of the second gear 19, the baffle 17 rotates around the T-shaped part 15. When the baffle 17 rotates, it drives the cleaning plate 20 to rotate. During the rotation of the cleaning plate 20, it can also scrape off the crystals on the outside of the filter frame 14, further preventing blockage and affecting the filtration of the filter frame 14.

[0049] When the pressure rod 23 descends to the bottom of the compression chamber 22, the lever 26 will descend below the sealing plate 24. As the lever 26 descends, it contacts the sealing plate 24, causing the lever 26 to rotate around the rotation axis and compress the torsion spring 27 (the lever 26 can only rotate in one direction). However, when the pressure rod 23 rises, the lever 26 will push the inclined surface of the sealing plate 24 from below, causing the sealing plate 24 to slide along the compression chamber 22 and compress the third spring 25. At this time, the sealing plate 24 will disengage from the compression chamber 22, and the compression chamber 22 will be in a state of communication with the outside world, preventing the solution from flowing back through negative pressure when the pressure rod 23 rises.

[0050] It is worth noting that when the filter frame 14 is filtering crystals and solution, the first cylinder 38 can still be started. When the first cylinder 38 is started and extends intermittently, it can continue to scrape off the crystals on the outer wall of the insert plate 5, the tank 1 and the cylinder 3.

[0051] Because the intake pipe 18 and the exhaust pipe 21 are slidably connected, the connection between the intake pipe 18 and the exhaust pipe 21 can be satisfied when the third cylinder 28 extends and retracts.

[0052] When the solution stops flowing outward, the bottom plate 12 is controlled by the closed group to separate from the tank 1. Then the crystals inside the tank 1 will stay on the bottom plate 12, which facilitates the collection of subsequent crystals.

[0053] As a further embodiment of the present invention, the rotating assembly includes a kit 29, which is rotatably connected to the top of the base plate 12. The top of the kit 29 is in contact with the bottom of the cylinder 3. A first gear ring 30 is fixedly connected to the kit 29. The first gear ring 30 meshes with a third gear 31. The third gear 31 rotates on the kit 29. A first bevel gear 32 is fixedly connected to the rotating shaft of the third gear 31. The first bevel gear 32 meshes with a second bevel gear 33. The second bevel gear 33 is rotatably connected to the inner bottom wall of the cylinder 3. A chain 34 is connected between the second bevel gear 33 and the rotating shaft of one of the first gears 8. A second gear ring 35 is slidably connected to the outside of the kit 29. The second gear ring 35 meshes with a second gear 19.

[0054] When the aforementioned transmission assembly is in operation, the second cylinder 6 and the first cylinder 38 intermittently extend and retract when the drainage assembly is working. When the first cylinder 38 extends, the tooth assembly 7 meshes with the first gear 8. When the first gear 8 rotates, it pulls the pull rope 9 to rewind. During the rotation of the first gear 8, the chain 34 drives the second bevel gear 33 to rotate. During the rotation of the second bevel gear 33, it meshes with the first bevel gear 32 and drives the first bevel gear 32 to rotate around the rotation axis. During the rotation of the first bevel gear 32, it drives the third gear 31 to rotate. During the rotation of the third gear 31, it meshes with the first gear ring 30 and drives the first gear ring 30 and the kit 29 to rotate. When the kit 29 rotates, it rotates around the rotation axis on the base plate 12, and the rotation of the kit 29 also drives the second gear ring 35 to rotate, so that the second gear ring 35 can mesh with the second gear 19, thereby driving the second gear 19 and the baffle 17 to rotate, so that the cleaning plate 20 can clean the filter frame 14.

[0055] As a further embodiment of the present invention, the outer wall of the kit 29 is embedded in the inner wall of the second toothed ring 35.

[0056] When the above solution is in operation, when the third cylinder 28 extends and pushes the filter frame 14 and the baffle 17 to rise, the second toothed ring 35 can slide and rise along the kit 29 when the baffle 17 rises from below. Furthermore, the second toothed ring 35 is also composed of two rings, and when it rises, it can also scrape off the crystals that are prevented from adhering to the kit 29.

[0057] As a further embodiment of the present invention, the cleaning plates 20 are all inclined.

[0058] When the above solution is in operation, the inclined cleaning plate 20, as it rotates with the baffle plate 17, can not only scrape the outer wall of the filter frame 14, but also push the crystals away from the filter frame 14, thereby facilitating the separation of the solution and crystals by the filter frame 14.

[0059] As a further embodiment of the present invention, the closing assembly includes a fourth cylinder 36, which is fixedly connected to the outer wall of the tank 1. The bottom end of the fourth cylinder 36 is rotatably connected to the bottom plate 12. A motor 37 is fixedly connected to the side wall of the fourth cylinder 36. The output shaft of the motor 37 passes through the fourth cylinder 36 and is fixedly connected to the rotation shaft of the bottom plate 12.

[0060] When the aforementioned closed assembly is in operation, the fourth cylinder 36 is activated, and the fourth cylinder 36 extends to drive the motor 37 and the base plate 12 to descend. When the base plate 12 descends, it drives the kit 29, the third gear 31 and the first bevel gear 32 to descend together. When the base plate 12 is separated from the tank body 1 to a certain extent, the motor 37 is activated. The motor 37 rotates at a certain angle to tilt the base plate 12. When the base plate 12 is tilted, the crystals on the top of the base plate 12 can fall to the outside. Furthermore, a shell for collecting crystals is provided below the tank body 1, which facilitates the falling of crystals.
