Description

Technical Field

[0001] This invention relates to the field of processing and aging technology, specifically to an aging device for processing nano-calcium carbonate. Background Technology

[0002] Nano-calcium carbonate is a new type of ultrafine solid powder material developed in the 1980s. Due to its special properties such as quantum size effect and small size effect, it is widely used in industries such as plastics, rubber, and papermaking. The aging process is one of the important steps in the production of nano-calcium carbonate.

[0003] In traditional aging processes, the aging equipment usually contains a certain amount of external oxygen. When aging sensitive systems, this can cause the nanoparticles and slurry to oxidize or react with impurities in the oxygen after contact with it, resulting in inconsistent product stability and purity. Summary of the Invention

One end of the two sets of pulleys B is connected to the connecting rod A. One end of the two sets of return pipes is located at the lower end of the fixed seat, and the other end of the return pipe extends through the fixed seat to the upper end and is connected to the aging tank. The inner wall of each set of return pipes is provided with a first guide groove that cooperates with the protrusion on the piston A to make the piston A move along the reciprocating screw A.

[0010] Preferably, one end of the connecting rod A is connected to the reciprocating lead screw A, and a piston A is provided inside the return pipe, wherein the piston A is connected to the ball nut assembly of the reciprocating lead screw A.

[0013] Preferably, multiple sets of blades are connected to the outside of the connecting shaft. One end of the reciprocating screw B passes through a sealing groove and is connected to the connecting shaft. A piston B is installed inside the guide tube A.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This invention can gradually form an inert environment inside the aging tank, thereby preventing the nano-calcium carbonate particles from undergoing oxidation reactions with the slurry in an aerobic environment, which would affect the purity and performance of the product. Furthermore, after the aging tank is filled with inert nitrogen, oxygen can be effectively isolated, preventing the surface of the nanoparticles from being oxidized and ensuring the chemical stability of the product. At the same time, the inert environment can inhibit the side reactions between oxygen or other active gases in the aging environment and the components in the slurry, further improving the purity and quality consistency of the nano-calcium carbonate.

[0018] 2. This invention allows the heat transfer oil to flow inside the storage tank, avoiding temperature stratification in localized areas due to uneven heat exchange. This results in a more uniform overall temperature of the heat transfer oil, ensuring stable heating of the aging tank and the return slurry. Simultaneously, the eddy current breaks up the thermal boundary layer formed when the heat transfer oil is stationary, accelerating the heat transfer speed within the oil. This allows for more thorough contact between the heat transfer oil and the outer wall of the aging tank and the return pipe, improving heat exchange efficiency and reducing energy waste.

[0019] 3. In this invention, after the slurry is heated by the heat transfer oil, the aging process is ensured to take place in a stable temperature environment, which is conducive to the uniform growth and structural stability of nano-calcium carbonate crystals. At the same time, during the heating process, the temperature and state of the refluxed slurry are closer to the reaction conditions in the aging tank. After re-entering the aging tank, it can mix more quickly and evenly with the original slurry in the aging tank, avoiding the problem of uneven reaction caused by local temperature differences and improving the consistency of product quality.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0031] Reference Figures 1 to 9 The present invention provides an aging device for processing nano-calcium carbonate, including an aging tank 2 installed inside a fixed base 1, a rotating shaft 4 rotating inside the aging tank 2, a stirring rod 5 connected to the outside of the rotating shaft 4, a pulley A6 rotating at the upper end of the aging tank 2, pulleys B8 rotating on both sides of the aging tank 2, and a return pipe 9 connected to both sides of the aging tank 2. A connecting rod A10 and a reciprocating screw A12 rotating inside the return pipe 9.

[0032] A half gear 16 rotates on the upper end of the pulley A6. A gear 17 meshes with one side of the half gear 16. A reset structure 18 is connected to one end of the gear 17. A movable frame 19 is connected to the other end of the gear 17.

[0033] A storage tank 14 is provided on the outside of the aging tank 2. A sealing groove 33 is installed on the other side of the storage tank 14. A drive motor is provided at the bottom of the sealing groove 33. A connecting shaft 22 rotates inside the sealing groove 33. The bottom end of the connecting shaft 22 extends to the outside of the sealing groove 33 and is connected to the drive motor. A guide tube A24 is provided at one end of the sealing groove 33. A reciprocating screw B23 rotates inside the guide tube A24. One side of the guide tube A24 is connected to the aging tank 2. A connecting plate 29 is connected to one end of the guide tube A24. A pull rod 30 is connected to one end of the connecting plate 29. A guide tube B32 is connected to the upper end of the aging tank 2.

[0034] In an optional embodiment, a motor 3 is provided at the lower end of the aging tank 2. The output end of the motor 3 is connected to the rotating shaft 4, and the other end of the rotating shaft 4 extends through the aging tank 2 to the upper end. The outer side of the other end of the rotating shaft 4 is connected to the pulley A6, which is located on the upper surface of the aging tank 2. When using the equipment, the operator places the slurry to be aged inside the aging tank 2. After placement, the motor 3 is started. When the motor 3 is started, it drives the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it synchronously drives the stirring rod 5 to rotate inside the aging tank 2. It should also be noted that those skilled in the art can set the rotation speed of the motor 3 to control the speed of the rotating shaft 4, thereby avoiding slurry sedimentation and ensuring uniform crystal growth.

[0035] In an optional embodiment, two sets of belts 7 are sleeved on the outer side of pulley A6, and the other ends of the two sets of belts 7 are sleeved on two sets of pulleys B8. One end of the two sets of pulleys B8 is connected to the connecting rod A10. One end of the two sets of return pipes 9 is located at the lower end of the fixed seat 1, and the other end of the return pipes 9 extends through the fixed seat 1 to the upper end and is connected to the aging tank 2. The inner wall of each set of return pipes 9 is provided with a first guide groove 11 that cooperates with the protrusion on the piston A13 to make the piston A13 move along the reciprocating screw A12. When the rotating shaft 4 rotates, it will drive the pulley A6 to rotate synchronously. When the pulley A6 rotates, it will drive the two sets of pulleys B8 to rotate synchronously through the two sets of belts 7. When the two sets of pulleys B8 rotate, it will drive the connecting rod A10 to rotate inside the return pipe 9.

[0036] In an optional embodiment, one end of the connecting rod A10 is connected to the reciprocating lead screw A12, and a piston A13 is provided inside the return pipe 9. The piston A13 is connected to the ball nut assembly of the reciprocating lead screw A12. When the connecting rod A10 rotates, it synchronously drives the reciprocating lead screw A12 to rotate. When the reciprocating lead screw A12 rotates, it drives the piston A13 to reciprocate outside the reciprocating lead screw A12. (See reference...) Figure 9 As shown, when piston A13 reciprocates, because the return pipe 9 is connected to the aging tank 2, the piston A13 will continuously draw the slurry from the aging tank 2 into the return pipe 9. Then, the slurry that has entered the return pipe 9 will be discharged again through the return pipe 9. After the slurry is discharged through the return pipe 9, it will flow back into the aging tank 2, thereby enhancing the mixing uniformity.

[0037] In an optional embodiment, the storage tank 14 has an opening at one end, and a portion of the two sets of return pipes 9 are located inside the storage tank 14, with heat-conducting oil added inside the storage tank 14.

[0038] In an optional embodiment, one end of the half gear 16 is connected to the rotating shaft 4, one end of the movable frame 19 is fixedly connected to the gear 17, and the other end of the movable frame 19 is fixedly connected to a comb plate 20. The comb plate 20 extends into the storage tank 14 through a slot. As described above, while the rotating shaft 4 drives the pulley A6 to rotate, the rotating shaft 4 will synchronously drive the half gear 16 to rotate. When the half gear 16 rotates, it will synchronously drive the gear 17 to rotate. When the gear 17 rotates, the gear 17 will drive the reset structure 18 to rotate synchronously. At the same time, it will also drive the movable frame 19 to move synchronously along the arc trajectory. When the movable frame 19 moves, it will synchronously drive the comb plate 20 to move inside the storage tank 14. When the comb plate 20 moves inside the storage tank 14, the comb plate 20 will come into contact with the heat transfer oil. Because the half gear 16 is a half-tooth design, after the half gear 16 drives the gear 17 to rotate a certain angle, the half gear 16 will disengage from the gear 17. At this time, the gear 17 will be reset by the torque of the reset structure 18. At this time, the heat transfer oil will be moved by the movement of the comb plate 20. It should also be noted that: see Figure 7 As shown, the reset structure 18 may include a stabilizer, a gear shaft that rotates on the stabilizer and is connected to the gear 17, and a torsion spring that surrounds the outside of the gear shaft and is connected to the gear 17 and the stabilizer at both ends, respectively. The deformation generated when the torsion spring is compressed is small and will not affect the meshing relationship between the gear 17 and the half gear 16.

[0039] Additionally, it should be noted that when the movable frame 19 moves, the movable frame 19 and the storage tank 14 are not at the same center point, and the rotation angle of its gear 17 is relatively small, so the distance the movable frame 19 moves is relatively short. Therefore, when the movable frame 19 moves, it will move to a position outside the storage tank 14, thereby avoiding the situation where the movable frame 19 and the storage tank 14 are not at the same center point, which would prevent the movable frame 19 from being unable to move along the storage tank 14.

[0040] The comb plate 20 agitates the heat transfer oil, causing it to flow within the storage tank 14. This mixing prevents temperature stratification in localized areas due to uneven heat exchange, resulting in a more uniform overall temperature of the heat transfer oil. This, in turn, ensures stable heating of the aging tank 2 and the reflux slurry. Simultaneously, the flow breaks up the thermal boundary layer formed when the heat transfer oil is stationary, accelerating the heat transfer within the oil. This allows for more thorough contact between the heat transfer oil and the outer wall of the aging tank 2 and the reflux pipe 9, improving heat exchange efficiency and reducing energy waste.

[0041] Additionally, please refer to: Figure 7As shown, the comb plate 20 is composed of multiple pavers, which can move the heat transfer oil. The movement of the heat transfer oil by the half gear 16 driving the gear 17 is different from the movement of the heat transfer oil by the reset structure 18. Therefore, it increases the flow and mixing of the heat transfer oil. Also, because the comb plate 20 is composed of multiple pavers, the movement amplitude of the heat transfer oil is small, which stabilizes the flow and prevents the heat transfer oil from splashing from the groove. In addition, those skilled in the art can replace the comb plate 20 with a paddle shape to generate a larger thrust when the heat transfer oil flows, increasing the activity of the heat transfer oil. However, in this case, attention should be paid to the amount of heat transfer oil to avoid the above-mentioned splashing problem.

[0042] In an optional embodiment, multiple sets of blades 21 are connected to the outside of the connecting shaft 22. One end of the reciprocating screw B23 passes through the sealing groove 33 and is connected to the connecting shaft 22. A piston B25 is provided inside the guide tube A24. The piston B25 is connected to the ball nut pair of the reciprocating screw B23. The inner wall of the guide tube A24 is provided with a second guide groove that cooperates with the protrusion on the piston B25 to make the piston B25 move along the reciprocating screw B23. A hose A26 is connected to one side of the guide tube A24. The other end of the hose A26 is connected to the nitrogen tank. A hose B27 is connected to the other side of the guide tube A24. The other end of the hose B27 is connected to the aging tank 2. A one-way valve is provided at the connection between the hose B27 and the aging tank 2.

[0043] Multiple sets of blades 21 are driven to rotate by a drive motor. When multiple sets of blades 21 rotate, they will synchronously drive the connecting shaft 22 to rotate. When the connecting shaft 22 rotates, it will synchronously drive the reciprocating screw B23 to rotate. When the reciprocating screw B23 rotates, it will drive the piston B25 to move back and forth in the guide tube A24. Since the hose A26 is connected to the nitrogen tank, when the piston B25 rises, some gas will be drawn into the guide tube A24 through the hose A26. After the nitrogen enters the guide tube A24, it will enter the aging tank 2 through the hose B27. Due to the one-way valve at the connection between the hose B27 and the aging tank 2, the nitrogen will only enter the aging tank 2, thereby preventing the gas inside the aging tank 2 from flowing back into the hose B27.

[0044] The amount of nitrogen introduced can be adjusted by the staff according to the actual aging time, so that the nitrogen gradually replaces the oxygen inside the aging tank 2 according to the aging time, ensuring the formation of an inert environment while avoiding sudden pressure changes in the device due to a large amount of nitrogen injected at one time, which would affect the stability of the aging reaction.

[0045] In an optional embodiment, one end of the guide tube A24 is movably connected to two sets of connecting rods B28. One end of the two sets of connecting rods B28 located outside the guide tube A24 is connected to a connecting plate 29, and the other end of the connecting plate 29 is connected to a pull rod 30. As described above, when the reciprocating screw B23 rotates to drive the piston B25 to rise, as the position of the piston B25 gradually moves upward, after the piston B25 moves to a certain height, it will contact the two sets of connecting rods B28. A sealing ring is provided at the connection between the two sets of connecting rods B28 and the guide tube A24, thereby preventing gas containing impurities from entering the interior of the guide tube A24 at the connection between the connecting rods B28 and the guide tube A24. After the piston B25 contacts the two sets of connecting rods B28, the piston B25 will push the two sets of connecting rods B28 to rise synchronously. When the two sets of connecting rods B28 rise, they will push the connecting plate 29 to move upward synchronously.

[0046] In an optional embodiment, a piston C31 is fixedly connected to the other end of the pull rod 30. The piston C31 is located inside the guide tube B32, and the inner diameter of the guide tube B32 matches that of the piston C31. A one-way valve is provided at the connection between the guide tube B32 and the aging tank 2. As described above, when the connecting plate 29 moves, it will simultaneously pull the pull rod 30 to move. When the pull rod 30 moves, it will simultaneously pull the piston C31 to rise inside the guide tube B32. When the piston C31 rises, it will draw oxygen out of the aging tank 2. At the same time, nitrogen is injected into the aging tank 2 as described above, thereby forming a circulation, so that... While nitrogen is injected into aging tank 2, oxygen is extracted, thus gradually creating an inert environment inside aging tank 2. This prevents oxidation of the nanoparticle surface or reaction with impurities, thereby preventing the nano-calcium carbonate particles from undergoing oxidation with the slurry in an aerobic environment, which would affect the purity and performance of the product. Furthermore, once aging tank 2 is filled with inert nitrogen, it effectively isolates oxygen, preventing the nanoparticle surface from being oxidized and ensuring the chemical stability of the product. At the same time, the inert environment can inhibit side reactions between oxygen or other active gases in the aging environment and the components in the slurry, further improving the purity and quality consistency of the nano-calcium carbonate.

[0047] Working Principle: When using the equipment, the operator places the slurry to be aged into the aging tank 2. After placement, the motor 3 is started. When the motor 3 starts, it drives the rotating shaft 4 to rotate. As the rotating shaft 4 rotates, it synchronously drives the stirring rod 5 to rotate inside the aging tank 2. As the rotating shaft 4 rotates, it synchronously drives the pulley A6 to rotate. As the pulley A6 rotates, it synchronously drives the two sets of pulleys B8 to rotate through the two sets of belts 7. The connecting rod A10 will rotate inside the return pipe 9. When the connecting rod A10 rotates, it will synchronously drive the reciprocating screw A12 to rotate. When the reciprocating screw A12 rotates, it will drive the piston A13 to reciprocate outside the reciprocating screw A12. As the piston A13 reciprocates, since the return pipe 9 is connected to the aging tank 2, the piston A13 will continuously draw the slurry at the bottom of the aging tank 2 into the return pipe 9 and discharge the slurry that has entered the return pipe 9 through the return pipe 9.

[0048] While the rotating shaft 4 drives the pulley A6 to rotate, the rotating shaft 4 will synchronously drive the half gear 16 to rotate. When the half gear 16 rotates, it will synchronously drive the gear 17 to rotate. When the gear 17 rotates, it will drive the reset structure 18 to rotate synchronously. When the gear 17 rotates, it will also drive the movable frame 19 to move synchronously along the arc trajectory. When the movable frame 19 moves, it will synchronously drive the comb plate 20 to move inside the storage tank 14. The heat transfer oil will be agitated through the comb plate 20.

[0049] When the multiple sets of blades 21 rotate, they will synchronously drive the connecting shaft 22 to rotate. When the connecting shaft 22 rotates, it will synchronously drive the reciprocating screw B23 to rotate. When the reciprocating screw B23 rotates, it will drive the piston B25 to move back and forth in the guide tube A24. Since the hose A26 is connected to the nitrogen tank, when the piston B25 rises, some gas will be drawn into the guide tube A24 through the hose A26. After the nitrogen enters the guide tube A24, it will enter the aging tank 2 through the hose B27.

[0050] As piston B25 gradually moves upward, it will contact the two sets of connecting rods B28 after reaching a certain height. Sealing rings are installed at the connections between the two sets of connecting rods B28 and guide tube A24 to prevent impurities from entering the guide tube A24. After piston B25 contacts the two sets of connecting rods B28, it will push the two sets of connecting rods B28 upward synchronously. During this upward movement... Simultaneously, the connecting plate 29 will be pushed upward. When the connecting plate 29 moves, the pull rod 30 will be pulled upward. When the pull rod 30 moves, the piston C31 will be pulled upward inside the guide tube B32. When the piston C31 rises, the oxygen inside the aging tank 2 will be extracted outward. At the same time, nitrogen will be injected into the aging tank 2 as mentioned above, thus forming a cycle. This allows oxygen to be extracted while nitrogen is being injected into the aging tank 2, thereby gradually creating an inert environment inside the aging tank 2.

[0051] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
