Description

Technical Field

[0001] This utility model relates to the field of nano-calcium carbonate production technology, specifically a nano-calcium carbonate sol extrusion device. Background Technology

[0002] Nano-calcium carbonate is a novel ultrafine solid material, belonging to the category of nanomaterials. Its particle size ranges from 1 to 100 nanometers, exhibiting unique crystal structures and variations in surface electronic structure, resulting in many distinctive properties. Nano-calcium carbonate sol is a special dispersion system in which nano-calcium carbonate particles are uniformly dispersed in a liquid, forming a stable suspension. This sol possesses many unique physical and chemical properties, making it widely applicable in various fields.

[0003] Patent CN209997631U discloses a nano-calcium carbonate sol extrusion device, which includes a reaction vessel. The upper end of the reaction vessel is rotatably connected to a top cover via a rotating shaft. A handle is fixedly connected to the upper surface of the top cover. An insert block is fixedly connected to the left side of the top cover. An insert plate is rotatably connected to the left side of the reaction vessel. The insert block is inserted into the insert plate. The device breaks and disperses the nano-calcium carbonate by using a paddle, thereby reducing the probability of nano-calcium carbonate agglomeration. Furthermore, the rotating stirring blades ensure that the nano-calcium carbonate and water are mixed evenly, making it easier to discharge the nano-calcium carbonate sol.

[0004] However, the existing device directly pours nano-calcium carbonate into the storage chamber and then controls the discharge of nano-calcium carbonate through a solenoid valve. However, the nano-calcium carbonate in the storage chamber is prone to agglomeration due to its own and external factors, which leads to it being compacted in the storage chamber and unable to pass through the solenoid valve into the reaction vessel. This affects the subsequent mixing and stirring of nano-calcium carbonate sol for production and discharge. To address this issue, a nano-calcium carbonate sol extrusion device is proposed to solve the problem that the calcium carbonate in the existing extrusion device is prone to agglomeration and cannot be discharged into the device to react and generate sol.

[0022] 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 protection scope of the present utility model.

[0023] Example: See Figure 1-4A nano-calcium carbonate sol extrusion device includes a reaction tank 1, a sealing cover 2 on the top of the reaction tank 1, an inlet 3 and a discharge port 4 on the top of the sealing cover 2 and the bottom of the reaction tank 1 respectively, a sealing plug 5 in the inner cavity of the discharge port 4, a water inlet pipe 6 at one end of the reaction tank 1, a stirring shaft 7 and a stirring plate 8 in the inner cavity of the reaction tank 1, a motor 9 fixedly connected to the top of the sealing cover 2, a material distribution plate 10 in the inner cavity of the reaction tank 1, a plurality of slots in the bottom of the inner cavity of the material distribution plate 10 and a scraper 11 and a retaining ring 16, rollers 12 at both ends of the scraper 11, the rollers 12 being rotatably connected to the scraper 11 by a rotating shaft 13, a gear 14 fixedly connected to the end of the rotating shaft 13, teeth 15 at the contact point between the gear 14 and the material distribution plate 10, a feeding mechanism 17 in the inner cavity of the inlet 3, and a connecting rod 20 connecting the sealing cover 2 and the material distribution plate 10.

[0024] Furthermore, the output shaft of the motor 9 passes through the sealing cover 2 and is fixedly connected to the stirring shaft 7, and multiple stirring plates 8 are evenly and symmetrically fixed on the outer ring of the stirring shaft 7.

[0025] Furthermore, the bottom of the scraper 11 and the roller 12 are in contact with the bottom of the inner cavity of the material distribution plate 10, and the retaining ring 16 is fixedly connected to the material distribution plate 10. The gear 14 is located in the area formed by the retaining ring 16 and the material distribution plate 10 and meshes with the teeth 15.

[0026] Furthermore, the feeding mechanism 17 includes a rotating rod 171 disposed in the feed inlet 3. The rotating rod 171 is rotatably disposed in the inner cavity of the feed inlet 3 by means of a fixing plate 173. The intersection of the rotating rod 171 and the fixing plate 173 is connected by a bearing. An auger 172 is disposed on the outside of the rotating rod 171.

[0027] Furthermore, sprockets 174 are fixedly connected to the outer ring of the bottom of the rotating rod 171 and the outer ring of the stirring shaft 7. The two sprockets 174 are fixedly connected by a chain 175. When nano-calcium carbonate is introduced into the reaction tank 1 from the feed inlet 3, the sprockets 174 on the rotating rod 171, which are rotated in conjunction with the stirring shaft 7 and the fixed plate 173, and the connecting chain 175, can drive the auger 172 outside the rotating rod 171 to rotate, thereby quickly augering the nano-calcium carbonate in the feed inlet 3 into the interior of the reaction tank 1 to react with water, ensuring the production efficiency of nano-calcium carbonate sol.

[0028] Furthermore, a feed hopper 18 is provided at the top of the feed inlet 3, and a cover 19 is hinged to the top of the feed hopper 18. The feed hopper 18 ensures that the nano-calcium carbonate can smoothly enter the feed inlet 3 and pass through the cover 2 into the reaction tank 1. The cover 19 can be closed during the reaction to produce nano-calcium carbonate sol to prevent external impurities from entering the reaction tank 1 and affecting the production of nano-calcium carbonate sol.

[0029] Working principle: When using this nano-calcium carbonate sol extrusion device, water is injected into the reaction tank 1 through the water inlet pipe 6. Then, the required amount of nano-calcium carbonate is introduced into the distribution plate 10 inside the reaction tank 1 through the feed port 3. While being stirred by the motor 9, stirring shaft 7 and stirring plate 8, the rotating roller 12 is driven by the gear 14 and teeth 15 on the outside of the rotating shaft 13 to grind the nano-calcium carbonate to prevent agglomeration. At the same time, the scraper 11, which rotates with the stirring shaft 7, evenly disperses the calcium carbonate from the slots into the reaction tank 1 to form nano-calcium carbonate sol. This solves the problem that calcium carbonate in the existing extrusion device is prone to agglomeration and cannot be discharged into the device to react and form sol. After the nano-calcium carbonate sol is formed, the sealing plug 5 is removed, and the nano-calcium carbonate sol can be discharged from the discharge port 4 to facilitate the subsequent production of nano-calcium carbonate sol.
