Description

Technical Field

[0001] This utility model relates to the field of cored titanium dioxide preparation technology, and in particular to a component preparation device for high-performance water-based cored titanium dioxide. Background Technology

[0002] Cored titanium dioxide is a titanium dioxide product processed using a special technique. One or more layers of inorganic oxides (such as oxides of silicon, aluminum, zirconium, etc.) are coated onto the surface of ordinary titanium dioxide to improve its properties and expand its application areas. The preparation of cored titanium dioxide is based on surface modification technology, using physical or chemical methods to uniformly coat the surface of titanium dioxide particles with one or more layers of inorganic oxides. This coating layer can alter the surface properties of titanium dioxide, such as improving its dispersibility, weather resistance, and chemical corrosion resistance, while also adjusting its optical properties, such as refractive index and hiding power.

[0003] Titanium dioxide is added to an appropriate amount of water, along with a dispersant. The titanium dioxide particles are then fully dispersed in the water using methods such as high-speed stirring or sand milling to form a stable suspension. The type and amount of dispersant affect the dispersion effect of the titanium dioxide. Commonly used dispersants include sodium hexametaphosphate and sodium polyacrylate.

[0004] The coating agent solution is slowly added to the titanium dioxide suspension while continuously stirring. Under certain temperature and pH conditions, the metal ions in the coating agent undergo hydrolysis, generating hydroxide or oxide precipitates that deposit on the surface of the titanium dioxide particles, forming a coating layer.

[0005] The mixing and stirring method of the coating agent solution and titanium dioxide suspension is different from that of a common reactor. A common reactor can quickly stir and mix by starting the stirring element through a drive structure, while the mixing of the coating agent solution and titanium dioxide suspension by the collision of liquids will result in a better coating effect. Therefore, this application proposes a mixing and stirring device for the preparation of cored titanium dioxide. Utility Model Content

Detailed Implementation

[0023] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0024] like Figures 1-3 As shown in the figure, this utility model embodiment proposes a component mixing device for preparing high-performance water-based encapsulated titanium dioxide. This device can precisely control the amount of raw materials added, achieving efficient and uniform mixing, thus providing a reliable guarantee for the preparation of high-performance water-based encapsulated titanium dioxide. The specific structure and technical content are as follows:

[0025] The vessel body 1, as the core container of the apparatus, is used to hold and mix various raw materials required for the preparation of high-performance water-based encapsulated titanium dioxide. The vessel body 1 is made of high-strength, corrosion-resistant stainless steel to ensure it can withstand the erosion of various chemicals during long-term use, guaranteeing the stability and reliability of the apparatus. Three mounting bases are installed on the vessel body 1, evenly distributed around it, providing stable mounting positions for the support legs 4.

[0026] Support leg 4: Installed at the bottom of the mounting base, it supports the vessel body 1. The support leg 4 is made of sturdy metal material and has anti-slip pads on the bottom to ensure the stability of the device during operation and prevent shaking from affecting the mixing effect.

[0027] The reactor body 1 is externally enclosed by a heating jacket 2, forming a sealed chamber between the heating jacket 2 and the reactor body 1. By introducing a heat medium (such as steam or heat transfer oil) into the heating jacket 2, the raw materials inside the reactor body 1 can be heated to meet the temperature requirements in the preparation process of high-performance water-based cored titanium dioxide. The heating jacket 2 adopts a highly efficient heat transfer design, which can quickly and uniformly transfer heat to the raw materials inside the reactor body 1, improving reaction efficiency. Simultaneously, the heating jacket 2 is equipped with temperature and pressure sensors to monitor the temperature and pressure of the heat medium in real time, ensuring the safety and reliability of the heating process.

[0028] Top cover 3: Installed on the upper end of the vessel body 1, and sealed to the vessel body 1 to prevent raw material leakage. The top cover 3 is detachable for easy cleaning and maintenance of the interior of the vessel body 1; a pressure relief valve is installed on the top cover 3 to ensure that the interior of the vessel body 1 is within a safe pressure range.

[0029] Functional tube 5: Installed on the upper end of the cover 3, the upper end of functional tube 5 is equipped with an openable sealing cap. After opening the sealing cap, weighed powder raw materials can be added through functional tube 5, and the inner wall of the vessel body 1 can also be rinsed using a water pipe. Functional tube 5 is equipped with a valve to control the inflow and outflow of materials. In addition, functional tube 5 can also serve as an observation port, allowing operators to easily observe the situation inside the vessel body 1.

[0030] The mixing assembly includes multiple connecting pipes 6 that are installed through the upper cover 3. The connecting pipes 6 are made of corrosion-resistant materials, such as polytetrafluoroethylene (PTFE). The connecting pipes 6 can be connected to a metering pump, which allows for precise control of the amount of raw materials added, ensuring quantitative delivery of the raw materials into the reactor body 1 via the connecting pipes 6. This quantitative addition method ensures accurate proportions between the raw materials, thereby improving the quality stability of the high-performance water-based encapsulated titanium dioxide.

[0031] Raw materials: Selecting suitable anatase or rutile titanium dioxide as the base material, its purity, particle size distribution, and other performance indicators will affect the quality of the final coated titanium dioxide. Coating agents: Commonly used coating agents include sodium silicate, aluminum sulfate, zirconium oxychloride, etc., selected according to the required coating layer composition and properties. Other auxiliary reagents: Such as acids (hydrochloric acid, sulfuric acid, etc.), alkalis (sodium hydroxide, etc.), dispersants, etc., are used to adjust the pH value of the reaction system, promote the coating reaction, and improve the dispersibility of titanium dioxide.

[0032] In addition, a pH meter and a temperature sensor can be installed on the connecting pipe 6. The pH meter is used to monitor the acidity or alkalinity of the material inside the vessel 1 in real time so as to adjust the reaction conditions in a timely manner; the temperature sensor is used to monitor the temperature of the material to ensure that the reaction takes place within a suitable temperature range.

[0033] The drive structure 8 is mounted on the upper cover 3. The counter-current mixing assembly includes a shaft 9 mounted on the drive structure 8. The drive structure 8 uses a high-performance motor (or other suitable power source selected according to actual needs) as its power core and is equipped with a high-precision reduction mechanism to stably output appropriate torque and speed. The drive structure 8 is connected to the shaft 9 through a reliable coupling, enabling the shaft 9 to rotate quickly and smoothly. The shaft 9 is made of high-strength, corrosion-resistant stainless steel to ensure sufficient strength and stability during rotation.

[0034] A first helical blade assembly 12 and a second helical blade assembly 13, facing opposite directions, are mounted on the shaft 9. A first mounting sleeve 11 and a second mounting sleeve 15 are fitted onto the outside of the shaft 9. Both the first mounting sleeve 11 and the second mounting sleeve 15 are fixed to the shaft 9 by bolts. This detachable installation method facilitates the replacement and maintenance of the helical blade assemblies. The first helical blade assembly 12 is fixed to the first mounting sleeve 11, and the second helical blade assembly 13 is fixed to the second mounting sleeve 15.

[0035] When shaft 9 rotates under the drive of drive structure 8, the first helical blade group 12 and the second helical blade group 13 can achieve counter-current flow of raw materials. The rotation of the first helical blade group 12 conveys the liquid raw material on the upper side downwards, while the rotation of the second helical blade group 13 conveys the liquid raw material on the upper side upwards, thus achieving counter-current flow of raw materials. This counter-current mixing method enables the raw materials to form strong convection within the reactor body 1, greatly improving mixing efficiency and ensuring thorough and uniform mixing of the raw materials, which is beneficial for the smooth progress of the preparation reaction of high-performance water-based encapsulated titanium dioxide.

[0036] Multiple stirring rods 14 are fixed on the stirring component, located between the first helical blade group 12 and the second helical blade group 13. The stirring rods 14 employ a special shape and material design to further stir and shear the raw materials within the vessel body 1 during rotation, thereby enhancing the mixing effect. The stirring rods 14, in conjunction with the helical blade group, form a multi-layered mixing system, ensuring that the raw materials are fully mixed and dispersed within the vessel body 1.

[0037] The inner wall of the vessel body 1 is fixed with a flow-blocking toothed plate 10, which is made of stainless steel and has high strength and corrosion resistance. The flow-blocking toothed plate 10 adopts a special shape and arrangement, which can generate resistance during the flow of raw materials, change the flow direction and speed of raw materials, increase the collision and mixing opportunities between raw materials, and thus improve the mixing effect.

[0038] When using this high-performance water-based encapsulated titanium dioxide preparation component mixing device, various raw materials are first quantitatively added to the reactor body 1 through the connecting pipe 6 under the control of the metering pump. Then, the heating jacket 2 is activated to heat the raw materials in the reactor body 1 to the required reaction temperature. Simultaneously, the drive structure 8 is activated, driving the shaft 9 to rotate, and the first spiral blade group 12 and the second spiral blade group 13 begin to work, causing relative flow and counterflow of the raw materials to achieve preliminary mixing. The stirring rod 14 further stirs and shears the raw materials during rotation, enhancing the mixing effect. The flow-blocking toothed plate 10 plays a role in assisting mixing and preventing the formation of dead zones in the raw materials. During the reaction, the pH value and temperature of the materials are monitored in real time by the detection device on the functional tube 5, and adjustments are made as needed. After the reaction is completed, the prepared high-performance water-based encapsulated titanium dioxide can be discharged through the functional tube 5, and then the inner wall of the reactor body 1 is rinsed using the functional tube 5 for the next production cycle.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
