[0004] In the existing technology, some nano-silica powder surface modification devices can only focus on a single function, and cannot combine multiple functions such as uniform mixing, cleaning and auxiliary heating during modification at the same time, which reduces production efficiency, increases maintenance difficulty and reduces the overall practicality of the equipment. In order to address the above problems, a nano-silica powder surface modification device is proposed. Utility Model Content

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.

[0032] Reference Figure 1 , Figure 3 and Figure 4 This utility model provides an embodiment of a nano-silica powder surface modification device, comprising a support substrate 1. The support substrate 1 serves as the basic load-bearing structure of the entire nano-silica powder surface modification device, providing an installation support platform for the heating and mixing mechanism, the detection mechanism, and the filtration mechanism. A heating and mixing mechanism is fixedly connected to the top of the support substrate 1. The heating and mixing mechanism includes a heating support base 2, which connects the support substrate 1 and the processing barrel 3, serving to support and fix the processing barrel 3, and simultaneously providing installation space for auxiliary components in the heating and mixing mechanism. The bottom of the heating support base 2 is fixedly connected to the top of the support substrate 1, and the top of the heating support base 2 is fixedly connected to the processing barrel. 3. The processing barrel 3 is the core working container for the surface modification of nano-silica powder. It is used to contain powder and modifier, and provides space for powder mixing and heating modification. The interior of the processing barrel 3 is rotatably connected to a rotating plate 10. A connecting rotating column 6 is fixedly connected to the adjacent side of the rotating plate 10. The rotating plate 10 extends and retracts according to the extension and retraction of the electric telescopic rod 8, thereby achieving mixing inside and cleaning inside the processing barrel 3 at the same time. The rotating plate 10 is fixedly connected to the connecting rotating column 6 and rotates with the rotating column 6, thereby driving the rotating mixing plate 7 to rotate. The motor 5 is connected to the rotating plate 10 and the rotating mixing plate 7, transmitting the power of the motor 5, and providing an installation position for the electric telescopic rod 8.

[0033] Multiple rotating mixing plates 7 are fixedly connected to the outside of the rotating column 6. These plates rotate within the processing barrel 3, stirring and mixing the nano-silica powder to promote full contact and reaction between the powder and the modifier. A heating column 12 is fixedly connected inside the processing barrel 3, generating heat to heat the nano-silica powder and provide the necessary temperature conditions for the surface modification reaction. A second heating column 13 is also fixedly connected inside the processing barrel 3, working in conjunction with the first heating column 12 to further improve the heating effect and temperature uniformity within the processing barrel 3, ensuring that the nano-silica powder undergoes surface modification at a suitable temperature. An auxiliary component, including a heating layer 14, is fixedly connected inside the heating support 2. The heating layer 14 serves as an auxiliary component... The core component of the auxiliary component generates heat and assists in heating the processing barrel 3, improving the heating efficiency and temperature stability of the device. The heating layer 14 is externally fixedly connected to the inside of the support connecting shell 4. The support connecting shell 4 protects the internal motor 5 and the heating layer 14 in the auxiliary component, and at the same time provides an installation and fixing structure for the motor 5 and the heating layer 14. Multiple heating springs 15 are fixedly connected inside the heating layer 14. The heating springs 15 provide a stable heat source for the entire auxiliary heating system, ensuring that the heating layer 14 can continuously and effectively assist in heating the processing barrel 3. An insulation layer 11 is fixedly connected inside the processing barrel 3. The insulation layer 11 wraps inside the processing barrel 3, reduces heat loss inside the processing barrel 3, maintains a stable temperature inside the barrel, and ensures that the surface modification reaction of the nano-silica powder is carried out under suitable temperature conditions.

[0034] A power assembly, including a motor 5, is fixedly connected to the top of the processing barrel 3. The motor 5, as the core of the power assembly, provides rotational power to the rotating plate 10, the connecting rotating column 6, and the rotating mixing plate 7, thereby achieving the stirring and mixing of the nano-silica powder inside the processing barrel 3. The external drive end of the motor 5 is fixedly connected to the inner side of the top of the connecting rotating column 6. A support connecting shell 4 is fixedly connected to the top of the processing barrel 3, and the external part of the motor 5 is fixedly connected inside the support connecting shell 4. An electric telescopic rod 8 is fixedly connected to the external part of the connecting rotating column 6. The electric telescopic rod 8 can adjust its telescopic length and change the position of its external connecting parts as needed to adapt to different processing requirements. A telescopic protective shell 9 is fixedly connected to the external part of the electric telescopic rod 8, covering the outside of the electric telescopic rod 8. The internal structure of the protective shell 9 cooperates with the electric telescopic rod 8 to ensure that the electric telescopic rod 8 remains stable during telescopic movement, without deviation or jamming. A detection mechanism is fixedly connected to the top of the support base plate 1, and a filtering mechanism is fixedly connected to the top of the support base plate 1.

[0035] Reference Figures 1 to 3The filtration mechanism includes a support box 17, which serves as the main body of the filtration mechanism, providing installation space for the double-layer filter plate 18. It also accommodates the material conveyed from the discharge pipe 16 and works in conjunction with the high-pressure water inlet pipe 19 for filtration. The double-layer filter plate 18 is fixedly connected inside the support box 17. The double-layer filter plate 18 filters the nano-silica powder conveyed from the processing drum 3, removing impurities and unqualified particles from the powder, thus improving product purity and quality. The top of the support box 17 is fixedly connected to the high-pressure water inlet pipe 19, which injects high-pressure water into the support box 17 for filtration. During the process, the nano-silica powder is washed to help remove impurities attached to the powder surface and improve the filtration effect. The processing barrel 3 is fixedly connected to the discharge pipe 16, which transports the surface-modified nano-silica powder in the processing barrel 3 to the support box 17 of the filtration mechanism to realize the material transfer. The output end of the discharge pipe 16 is fixedly connected to the bottom side of the support box 17. The detection mechanism includes a detection box 20, which serves as the main body of the detection mechanism and provides installation space for components such as the storage barrel 21. It is used to store the nano-silica powder to be tested and to perform relevant quality detection operations.

[0036] The bottom of the testing box 20 is fixedly connected to the top of the support base plate 1. Two storage bins 21 are fixedly connected to the top of the testing box 20. The storage bins 21 store the nano-silica powder to be tested, providing a material source for the testing work. An internal control component controls the discharge of the powder. The control component, including two electric valves 24, is fixedly connected inside the storage bins 21 to control the discharge of the nano-silica powder from the storage bins 21, achieving precise control of the feeding process and ensuring that the testing work can be carried out as needed. The electric valves 24 are externally fixedly connected inside the storage bins 21. The electric valve 24 is externally fixedly connected to a feed pipe 25, which connects the storage tank 21 and the detection box 20. This serves as a channel for the nano-silica powder to enter the detection box 20 from the storage tank 21, ensuring smooth material transport. The top of the storage tank 21 is fixedly connected to a connecting column 22, which connects the storage tank 21 and the uniform feeding plate 23. This column supports and fixes the uniform feeding plate 23, while also providing a channel for the powder to fall. The uniform feeding plate 23 is fixedly connected inside the connecting column 22. The uniform feeding plate 23 has multiple evenly distributed feeding holes, allowing the powder to fall evenly under gravity.

[0037] Working Principle: First, after starting the motor 5, the drive end drives the connecting rotating column 6 to rotate, which in turn causes the rotating mixing plate 7 fixed to the column to rotate synchronously. The rotating mixing plate evenly stirs the powder. At this time, the electric telescopic rod 8 adjusts the unfolding angle of the rotating plate 10 through the telescopic protective shell 9, so that the rotating plate 10 can more flexibly and fully contact the powder during the mixing process, while effectively scraping the barrel wall to achieve a self-cleaning function, preventing the powder from sticking to the barrel wall and keeping the equipment clean. At the same time, the heating column 12 and the heating column 13 start to work, raising the temperature inside the barrel through heating. Combined with the external insulation layer 11, heat loss is effectively reduced, ensuring the stability of the internal temperature. When the temperature inside the barrel is insufficient, the heating layer 14 and the heating spring 15 work together to supplement the heat, further enhancing the heating effect, forming a main and auxiliary temperature control system to ensure the smooth progress of the mixing process and achieve the ideal heating effect. Thus, the multiple functions of uniform mixing, cleaning, and auxiliary heating are used simultaneously, improving processing efficiency and enhancing the overall practicality of the equipment.

[0038] After the mixing and modification are completed, the material enters the support box 17 through the discharge pipe 16 and is filtered by the double-layer filter plate 18 for impurity classification. At this time, high-pressure water is injected into the high-pressure water inlet pipe 19 to flush the surface of the filter plate and improve the purity. The filtered powder enters the detection box 20. The raw material in the storage tank 21 is controlled by the electric valve 24 and transported to the uniform feeding plate 23 through the feed pipe 25. The plate achieves uniform spreading of raw materials through equidistantly distributed guide holes. During the detection process, the connecting column 22 serves as the feeding channel to ensure that the powder enters the detection station at a constant rate, realizing flexible control of raw material transportation and facilitating adjustment of the feeding amount according to production needs. The use of the uniform feeding plate 23 ensures the uniformity of raw material feeding, resulting in better product quality.
