Description

Technical Field

[0001] This utility model relates to the field of silica sol production and processing, and in particular to a silica sol purification and separation device. Background Technology

[0002] Silica sol, as an odorless and non-toxic colloidal solution, is an excellent adhesive due to its fine colloidal particles, large specific surface area, excellent dispersion and permeability, and the formation of silicon-oxygen bonds between particles after water evaporation. It is widely used in high-end fields such as electronics, coatings, and precision casting. Its performance requires extremely high purity, necessitating strict separation and purification during processing and production.

[0003] In existing technologies, silica sol purification often employs a single filter to remove impurities. However, as filtration proceeds, the filter easily becomes clogged with impurities, leading not only to low purification efficiency and insufficient purity of the finished product, but also to damage the dispersibility of silica sol particles, causing particle agglomeration. This, in turn, affects key properties such as adhesion and permeability, making it difficult to meet the requirements of high-purity applications such as electronic and precision casting. Furthermore, traditional equipment lacks efficient dispersion treatment for silica sol particles, further exacerbating the problems of incomplete purification and poor particle dispersibility, severely restricting the application effect and value of silica sol in high-end fields.

[0004] Therefore, those skilled in the art have provided a silica sol purification and separation apparatus to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a silica sol purification and separation device. This device features an integrated design that solves the problems of incomplete purification, low efficiency, and poor particle dispersion associated with traditional devices. The stirring blades and multi-zone ultrasonic probes work synergistically to efficiently break up silica sol agglomerates, ensuring thorough impurity removal. The graded filtration structure with coarse and fine membranes precisely intercepts impurities of different particle sizes, achieving nanoscale deep purification. No additional auxiliary equipment is required; the synergy of the rotating motor, transducer, and filter membrane significantly improves purification efficiency and product purity, ensuring the stability and storability of the silica sol dispersion. The compact tank structure, support legs for stable operation, and discharge pipe facilitate product collection make it suitable for the high-purity silica sol requirements of various fields such as electronics, coatings, and precision casting, achieving efficient purification across all scenarios and enhancing the performance and value of silica sol in high-end industrial applications.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A silica sol purification and separation device includes a tank body with an inner cavity. A coarse filter membrane is fixedly disposed in the inner cavity, and a fine filter membrane is fixedly disposed below the coarse filter membrane in the inner cavity. An ultrasonic generator is fixedly disposed on the outer wall of the tank body. Three first transducers are fixedly disposed on the outer wall of the tank body, and each first transducer is fixedly connected to a first ultrasonic probe. Each first ultrasonic probe is disposed in the inner cavity.

[0012] Through the above technical solution, the ultrasonic generator achieves a stable electrical connection with the first, second, and third transducers, accurately transmits high-frequency electrical signals, ensures that each transducer synchronously converts into mechanical vibration, and guarantees the coordinated and consistent ultrasonic action in multiple areas.

[0013] Furthermore, the coarse filter membrane has multiple coarse filtration pores, and the fine filter membrane has multiple fine filtration pores;

[0014] Through the above technical solution, multiple coarse pores on the coarse filtration membrane and multiple fine pores on the fine filtration membrane form a hierarchical interception structure, which is adapted to the filtration of impurities of different particle sizes.

[0033] Reference Figure 1 , Figure 4 , Figure 5 This utility model provides another specific embodiment:

[0034] A rotating shaft 12 is fixedly mounted on the output end of the rotating motor 3. Multiple stirring blades 13 are fixedly mounted on the rotating shaft 12. The rotating shaft 12 and the multiple stirring blades 13 constitute a stirring system. The stirring blades 13 rotate with the rotating shaft 12, thoroughly agitating the silica sol in the inner cavity 17. This, combined with multi-zone ultrasound, achieves uniform processing across the entire area, enhancing impurity removal and particle dispersion. The ultrasonic generator 7 is electrically connected to the first transducer 6, the second transducer 8, and the third transducer 9. The ultrasonic generator 7 achieves a stable electrical connection with the first transducer 6, the second transducer 8, and the third transducer 9, accurately transmitting high-frequency electrical signals to ensure that each transducer synchronously converts into mechanical vibration, guaranteeing the coordinated action of multi-zone ultrasound. Multiple coarse filter holes 20 are formed on the coarse filter membrane 18, and multiple fine filter holes 21 are formed on the fine filter membrane 19. The multiple coarse filter holes 20 on the coarse filter membrane 18 and the multiple fine filter holes 21 on the fine filter membrane 19 form a graded interception structure. The structure is adapted to filter impurities of different particle sizes. With the help of ultrasound and stirring, the accuracy of impurity separation is improved, ensuring the deep purification effect. The bottom of the tank 1 is fixedly equipped with a discharge pipe 11, which is connected to the inner cavity 17. The high-purity silica sol after ultrasound, stirring and graded filtration can be directly discharged. The structure is simple and adaptable to the continuous purification process, ensuring convenient and efficient collection of finished products. The lid 4 is fixedly equipped with a handle 2, which provides a convenient grip for opening and closing the lid 4. With the help of the connecting shaft 5, the lid 4 can be opened and closed flexibly, which is convenient for adding raw materials and maintaining the inner cavity 17, improving the ease of operation of the device. The bottom of the tank 1 is fixedly equipped with three support legs 10, which form a stable triangular support structure, providing a stable base for the operation of the device, offsetting the influence of stirring and ultrasonic vibration, ensuring the stability of the purification process, and improving the reliability of the equipment placement.

[0035] Working Principle: The operator pours the silica sol raw material into the inner cavity 17 of the tank 1. The tank lid 4 is flexibly opened and closed via a connecting shaft 5, and the handle 2 facilitates the operator's opening of the lid 4. After starting the rotating motor 3, its output shaft drives the rotating shaft 12 to rotate at high speed. The multi-layered stirring blades 13 on the rotating shaft 12 stir the silica sol in the inner cavity 17 without dead angles. On the one hand, this creates a dynamic flow field in the silica sol within the tank, preventing particles from settling due to gravity. On the other hand, it ensures full contact between the silica sol and the subsequent ultrasonic treatment area, improving the uniformity of the ultrasonic treatment. The ultrasonic generator 7 outputs a high-frequency electrical signal, which is transmitted to the first transducer 6, the second transducer 8, and the third transducer 9. These transducers convert electrical energy into mechanical vibration energy, which is transmitted to the silica sol through the corresponding first ultrasonic probe 14, second ultrasonic probe 15, and third ultrasonic probe 16. The first ultrasonic probe 14, located in the stirring area, generates a high-frequency vibration with an amplitude of approximately [insert value here], breaking up the micron-sized agglomerates in the silica sol. Simultaneously, salts and metal ion impurities adsorbed on the particle surface are removed. The second ultrasonic probe 15, located above the coarse filter membrane 18, further refines and disperses the coarsely filtered silica sol, ensuring uniform particle dispersion. The third ultrasonic probe 16, located above the fine filter membrane 19, performs a final ultrasonic treatment on the silica sol that is about to be filtered, completely destroying any remaining micro-agglomerates and ensuring the dispersion stability of the finished silica sol. During the filtration stage, the silica sol first flows through the coarse filter membrane 18, where the coarse filter pores 20 intercept large particle impurities that remain after ultrasonic treatment. Subsequently, the silica sol enters the area of ​​the fine filter membrane 19, where the fine filter pores 21 filter out even finer impurities. Through graded interception, deep purification is achieved. Finally, the high-purity silica sol, after ultrasonic dispersion and two-stage filtration, collects at the bottom of the tank 1 under gravity and is discharged through the discharge pipe 11. The three support legs 10 at the bottom of the tank 1 adopt a triangular distribution design to ensure the stability of the device during stirring and ultrasonic vibration, preventing displacement or overturning.
