Description

Technical Field

[0001] This utility model relates to the field of nano-calcium carbonate activation and modification technology, specifically a nano-calcium carbonate activation and modification reaction vessel. Background Technology

[0002] Activated nano-calcium carbonate is nano-sized calcium carbonate that has undergone activation modification. It is odorless and tasteless, with nearly spherical particles. Due to the adsorption of an activating modifier on the particle surface, it possesses activation properties and is an excellent white reinforcing filler. It dissolves in water, decomposes in acid, and turns charred black upon burning, releasing carbon dioxide and generating calcium oxide. Activated nano-calcium carbonate is widely used in the rubber, plastics, and coating industries. A commonly used wet activation process for nano-calcium carbonate involves adding the activating modifier and nano-calcium carbonate into the apparatus, and then stirring with a stirring device to activate and modify the nano-calcium carbonate.

[0003] In the wet activation modification process, nano-calcium carbonate and an activating modifier are typically added to a reaction vessel, and a stirring device is used to achieve thorough mixing and surface modification. However, during stirring, the centrifugal force generated by rotation causes the activating modifier and nano-calcium carbonate to be thrown against the inner wall of the reaction vessel, resulting in uneven distribution of the materials within the vessel. Areas near the stirring center may experience poor mixing due to insufficient material concentration, while areas near the inner wall are prone to accumulation, affecting the uniformity of activation modification. Due to the uneven material distribution, the stirring time needs to be extended to achieve thorough mixing, which not only reduces production efficiency but may also lead to energy waste and localized overdose of the activating agent, affecting product quality.

When the motor is turned on, the rotating shaft drives the stirring rod and the spiral blade to rotate, thereby stirring and mixing the activating modifier and nano-calcium carbonate.

[0023] like Figures 1-4As shown, this utility model provides a technical solution: a nano-calcium carbonate activation and modification reactor, including a reactor body 1.

[0024] Synchronous pulley 60 is rotatably connected to the top of the reactor body 1. A rotating rod 61 is provided on the top of the reactor body 1, passing through synchronous pulley 60 and fixedly connected to it. The bottom of rotating rod 61 passes through the reactor body 1 and is rotatably connected to it. A gear 62 is passed through and fixed to the bottom of rotating rod 61. The top of gear 62 is rotatably connected to the top of the inner wall of the reactor body 1. Synchronous pulley 60 is fixed to the surface of the output shaft of motor 51. A gear 64 is rotatably connected to the top of the inner wall of the reactor body 1. Gear 62 meshes with gear 64. A connecting hole 65 is provided inside gear 64. An abutment rod 66 is fitted to the inner wall of the connecting hole 65. A stabilizing frame 67 is fixed to the inner wall of the reactor body 1. A moving rod 68 is slidably connected to the inner side of the stabilizing frame 67. The bottom of the abutment rod 66 is fixed to the top of the moving rod 68. A fixing column 69 is fixed to the top of the inner wall of the reactor body 1. A spring 600 is fixed to the outer surface of the fixing column 69. One end of the spring 600 away from the fixed post 69 is fixed to the end of the moving rod 68 near the fixed post 69. A spoiler 601 is fixed to the bottom of the moving rod 68. Protrusions 603 are formed at both ends of the inner wall of the connecting hole 65, and recesses 602 are formed at both ends of the inner wall of the connecting hole 65 away from the protrusions 603. A synchronous belt drives the surfaces of synchronous pulley 60 and synchronous pulley 63. A perforation is formed on the surface of the spoiler 601. When the motor 51 operates, the synchronous pulleys 60 and 60 are connected via the synchronous belt. 0. When rotating synchronously, the rotating rod 61 drives the gear 1 62 and gear 2 64 to rotate. The inner wall of the connecting hole 65 abuts against the surface of the contact rod 66. When the contact rod 66 moves with the connecting hole 65 to the protrusion 603, the contact rod 66 drives the moving rod 68 to move closer to each other. At the same time, the spring 600 is compressed, and the moving rod 68 synchronously drives the baffle 601 to move closer to each other. This allows the activating modifier and nano calcium carbonate affected by centrifugal force to be gathered inward, improving the uniformity of stirring and the stirring efficiency.

[0025] A connecting frame 50 is fixed to the top of the reactor body 1, and a motor 51 is fixed to the inside of the connecting frame 50. The bottom of the output shaft of the motor 51 passes through the reactor body 1, and the output shaft of the motor 51 is rotatably connected to the reactor body 1. A rotating shaft 52 is rotatably connected to the top of the inner wall of the reactor body 1. The top of the rotating shaft 52 is fixed to the bottom of the output shaft of the motor 51, and the bottom of the rotating shaft 52 passes through a fixed column 69. A stirring rod 54 is fixed to the outer surface of the rotating shaft 52, and a spiral blade 53 is fixed to the outer surface of the rotating shaft 52. When the motor 51 is turned on, the rotating shaft 52 drives the stirring rod 54 and the spiral blade 53 to rotate, which can stir and mix the activating modifier and nano calcium carbonate. Through the spiral blade 53, the activating modifier and nano calcium carbonate that have settled to the bottom move upward, improving the stirring efficiency.

[0026] The reactor body 1 has a feed inlet 2 at the top, an exhaust outlet 3 at the top, and a discharge outlet 4 on the lower outer surface of the reactor body 1. A filter screen is installed on the top of the exhaust outlet 3 to facilitate the filtration of exhaust gas and avoid affecting personnel.

[0027] During processing, the activating modifier and nano-calcium carbonate are fed into the feed inlet 2, and the motor 51 is turned on simultaneously. The rotating shaft 52 rotates, which in turn drives the stirring rod 54 and the spiral blade 53 to rotate, thus mixing the activating modifier and nano-calcium carbonate. The spiral blade 53 causes the settled activating modifier and nano-calcium carbonate to rise, improving stirring efficiency. Simultaneously, while the motor 51 is working, the synchronous belt causes the synchronous pulley 63 and synchronous pulley 60 to rotate synchronously. The rotating rod 61 then drives gears 62 and 64 to rotate. At this time, the inner wall of the connecting hole 65 contacts the surface of the contact rod 66. When the contact rod 66 moves with the connecting hole 65 to the protrusion 603, the contact rod 66... The moving rods 68 move closer together, while the spring 600 is compressed. The moving rods 68 simultaneously move the baffles 601 closer together, which causes the activating modifier and nano-calcium carbonate affected by centrifugal force to gather inward, improving the uniformity of mixing and the mixing efficiency. The gear 64 continues to rotate, and the spring 600 is released, causing the contact rod 66 and the moving rod 68 to move into the recess 602, which causes the baffles 601 to move away from each other. Thus, while the motor 51 is working continuously, the baffles 601 move closer or further away from each other, improving the mixing efficiency. When the processing is completed, the material is discharged through the discharge port 4, and the reaction waste gas is discharged through the exhaust port 3 and filtered through the filter screen.

[0028] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
