The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0022] An embodiment of the present utility model provides an electrical device for preparing nano-calcium, such as Figures 1-4 As shown, the electrical device for preparing nano-calcium includes: a mixing kettle 1 for preparing nano-calcium, a heater 2 for heating is arranged inside the mixing kettle 1, and both the water inlet end and the water outlet end of the heater 2 extend outside the mixing kettle 1; a frame 3 fixed on the top of the mixing kettle 1, a transmission shaft 4 for transmission is rotatably installed on the frame 3; a stirring shaft 5 arranged inside the mixing kettle 1, the top end of the stirring shaft 5 is fixedly connected with the transmission shaft 4 through a coupling; a plurality of stirrers 6 assembled on the stirring shaft 5, the stirrers 6 are used for stirring nano-calcium raw materials; a speed reducer 7 and a variable-frequency motor 8 assembled on the frame 3, the input shaft of the speed reducer 7 is fixedly connected with the output shaft of the variable-frequency motor 8 through a coupling, and the output shaft of the speed reducer 7 is fixedly connected with the transmission shaft 4 through a coupling; a plurality of ultrasonic generators 22 fixed inside the mixing kettle 1; a filtering mechanism arranged on the mixing kettle 1, and the filtering mechanism is used for pre-filtering the hot water entering the heater 2.

[0023] It should be noted that although the traditional batch carbonization method can prepare nano-calcium carbonate, its inherent limitations significantly restrict its wide adoption in high-end application fields. Specifically, this method faces several challenges: First, during the carbonization reaction process, the product particle size is affected by multiple complex factors such as temperature and stirring speed, resulting in difficult-to-precisely-control particle size distribution, poor reproducibility, and difficulty in meeting the stringent market requirements for high uniformity of nano-material particle size; Second, there is a significant scale-up effect in the batch carbonization reactor, and the process parameters optimized under laboratory conditions often fail during industrial scale-up, leading to a decline in reaction efficiency and increased product quality fluctuations; Moreover, this method has a long cycle and limited single-equipment production capacity, which greatly restricts the improvement of production efficiency and increases production costs, and is not conducive to economically efficient large-scale production. Therefore, it is particularly important to explore a more precise, controllable, efficient, and economical nano-calcium carbonate preparation technology.

[0024] In this embodiment, the mixing kettle 1 is the core equipment for the preparation of nano calcium carbonate. A heater 2 for precisely controlling the reaction temperature is arranged in the mixing kettle 1. The pipeline of the heater 2 is arranged along the inner wall of the mixing kettle 1 without affecting the rotation of the stirring shaft 5. The water inlet end and the water outlet end of the heater 2 are both ingeniously designed outside the mixing kettle 1, facilitating the circulation of hot water and temperature regulation. The heater 2 realizes the rapid response and stable control of the temperature inside the kettle through the circulation of hot water, effectively solving the problem that the temperature fluctuation has a great influence on the particle size of the product in the traditional method. The temperature detection probe of the temperature detector arranged on the mixing kettle 1 can monitor the temperature change in real time. The frame 3 is firmly supported above the mixing kettle 1, and a transmission shaft 4 is installed thereon. Through the combined drive of the speed reducer 7 and the frequency conversion motor 8, the precise speed adjustment of the stirring shaft 5 is realized. The frequency conversion motor 8 provides power, and the speed reducer 7 ensures that the output torque is sufficient and the speed is adjustable to meet different stirring requirements. The stirring shaft 5 extends into the interior of the mixing kettle 1, and several stirrers 6 assembled thereon can effectively disperse and mix the nano calcium raw materials, improving the reaction uniformity and helping to generate nano calcium carbonate with more uniform particle size. The ultrasonic generator 22 is arranged along the inner wall of the mixing kettle 1, opposite to the heater 2, without affecting the rotation of the stirring shaft 5. A plurality of ultrasonic generators 22 are arranged at intervals along the height of the mixing kettle 1. The ultrasonic generator 22 fixed in the mixing kettle 1 utilizes the cavitation effect of ultrasonic waves to further enhance the interaction between materials, promote the formation of nano particles, and help to reduce the particle size distribution range. The filtering mechanism arranged on the mixing kettle 1 pre-filters the hot water entering the heater 2 to ensure the purity of the water quality and avoid the adverse effects of impurities on the reaction process and product quality. This mixing device is designed considering the requirements of industrial scale-up. By optimizing the transmission system, stirring device and heating method, it reduces the problems of the decline of reaction efficiency and the fluctuation of product quality caused by scale-up, ensuring that the laboratory process conditions are still effective in industrial applications. The mixing device adopts a continuous or semi-continuous production method. Compared with the traditional batch carbonization method, it greatly shortens the reaction cycle, improves the production capacity of a single device, helps to reduce the production cost, and realizes economic and efficient large-scale production.

[0025] In a further preferred embodiment of the present invention, the filtering mechanism includes: a filter box 9 arranged on the mixing kettle 1, the water outlet end of the filter box 9 is fixedly communicated with the water inlet end of the heater 2 through a connecting pipe; a filter cylinder 10 arranged in the filter box 9 for filtering large impurities and detachable; a filter plate 11 assembled in the filter box 9, the filter plate 11 is used for filtering small impurities, the filter plate 11 divides the filter box 9 into two parts, and the filter cylinder 10 is located on the side of the filter box 9 close to the water inlet end; a box cover 12 arranged on the filter box 9 and detachable, and a water inlet pipe 13 for connecting a hot water supply device is fixedly communicated with the box cover 12.

[0026] In this embodiment, the filter tank 9 serves as the front-end device for filtering hot water. The filter tank 9 can effectively remove large impurities and some small impurities in the water, protect the heater 2 from damage by impurities, and ensure the purity of the hot water entering the mixing kettle 1. The filter cartridge 10 is arranged inside the filter tank 9, and its main function is to filter large impurities in the water, such as particulate matter, suspended matter, etc. Through the detachable design, the filter cartridge 10 is convenient for regular cleaning or replacement to ensure the filtering effect. A plurality of filter plates 11 are assembled in the filter tank 9. These filter plates 11 utilize the adsorption property of activated carbon to further remove small impurities, odors, pigments, and some scale in the water, improving the water quality. Water first enters the filter cartridge 10 through the water inlet end of the filter tank 9, and after preliminary filtration, it is further filtered by the filter plates 11, extending the service life of the heater 2 and ensuring the stability of the water quality during the preparation of nano-calcium. The tank cover 12 is installed on the filter tank 9 and is convenient for maintenance and cleaning through the detachable design. A water inlet pipe 13 is fixedly connected to the tank cover 12 for connecting to the hot water supply device to achieve the input of hot water. The design of the tank cover 12 enables users to easily open the tank cover for the maintenance and replacement of internal components when the filter cartridge 10 or filter plates 11 need to be replaced. The water inlet pipe 13 is responsible for introducing the hot water from the hot water supply device into the filter tank 9 and is the gateway for the hot water input of the entire filtering mechanism.

[0027] In a further preferred embodiment of the present utility model, there are a plurality of the filter plates 11, and they are arranged in parallel. A number of partition plates 14 for partitioning the space are fixedly installed in the filter tank 9. A partition plate 14 is provided between adjacent two filter plates 11. An overflow groove is provided at the top or bottom of the partition plate 14. A pull ring is fixedly installed on the filter cartridge 10.

[0028] In this embodiment, a number of partition plates 14 are fixedly installed in the filter tank 9. These partition plates divide the internal space of the filter tank 9 into multiple filtering areas. An overflow groove is formed on each partition plate 14, allowing water to flow smoothly between the partition plates 14 while maintaining the functional independence of each area. Water first flows into the filter cartridge 10 through the water inlet pipe 13 to filter large impurities, then is filtered by the filter plates 11 for small impurities, and then flows into the next filtering area through the overflow groove on the partition plate 14 for filtration, avoiding problems such as water flow short-circuit or excessive local flow rate leading to insufficient filtration, thereby improving the overall filtration efficiency. A pull ring is fixedly installed on the filter cartridge 10. This is a simple but practical design. The function of the pull ring is to provide a convenient lifting point for users, enabling them to easily take out the filter cartridge from the filter tank 9 when it needs to be replaced or cleaned.

[0032] In this embodiment, a liquid discharge pipe 18 is fixedly connected to one side of the mixing kettle 1. A valve is provided on the liquid discharge pipe 18, and this pipe is specifically used for emergency liquid discharge. When abnormal conditions occur inside the mixing kettle 1, such as too high pressure, over-limit liquid level, or the need to quickly empty the liquid, the liquid discharge pipe 18 can quickly and effectively discharge the liquid to ensure the safety of the equipment and the smooth progress of production; on the other side of the mixing kettle 1, a gas pipe is also fixedly connected, and this pipe is used to connect a gas supply device to supply carbon dioxide into the mixing kettle 1. The supply of carbon dioxide may play various roles in the preparation process of nano-calcium, such as adjusting the pH value, promoting chemical reactions, inhibiting the generation of impurities, etc., and the specific role depends on the requirements of the production process.

[0033] In a further preferred embodiment of the present utility model, a first feeding port 19 and a second feeding port 20 are provided on the mixing kettle 1. The first feeding port 19 is used for putting in additives, and the second feeding port 20 is used for putting in calcium hydroxide agents.

[0034] In this embodiment, a first feeding port 19 and a second feeding port 20 are respectively provided on the mixing kettle 1, and these two feeding ports are respectively used for putting in different types of raw materials. Specifically, the first feeding port 19 is specifically used for putting in additives, such as reaction catalysts, stabilizers or other additives, to improve or control the chemical reaction conditions in the preparation process of nano-calcium; while the second feeding port 20 is used for putting in the main reactant calcium hydroxide agent, which is the key raw material for preparing nano-calcium; by separately setting two feeding ports, the feeding ratio and sequence of additives and calcium hydroxide agents can be flexibly adjusted according to the requirements of the production process, so as to achieve precise control of the nano-calcium preparation process and improve the quality and output of the product; openable sealing covers are provided on both the first feeding port 19 and the second feeding port 20. These sealing covers are opened during feeding to smoothly put the raw materials into the mixing kettle; after feeding is completed, the sealing covers are closed and tightly sealed to prevent the reactants inside the mixing kettle from leaking out or external impurities from entering, ensuring the purity and stability of the reaction environment.

[0035] In a further preferred embodiment of the present utility model, lifting lugs 21 are symmetrically and fixedly installed on the mixing kettle 1, and a bearing bracket 16 is fixedly installed inside the mixing kettle 1, and the bearing bracket 16 is used for assembling the stirring shaft 5.

[0036] In this embodiment, lifting lugs 21 are symmetrically and fixedly installed on the mixing kettle 1. As connection points and stress points, the lifting lugs are usually designed with strengthened structures and can withstand large weights and tensile forces. Their main function is to facilitate the hoisting, transportation, positioning, and fixing of the mixing kettle during the installation process. A bearing bracket 16 is fixedly installed inside the mixing kettle 1, and this bearing bracket is specifically used for assembling the stirring shaft 5, which can ensure that the stirring shaft 5 rotates stably and smoothly while reducing friction and wear.
