Description

Technical Field

[0001] This utility model relates to the field of ink processing technology, and in particular to a nano-aluminum powder ink emulsification device. Background Technology

[0002] Nano-aluminum powder ink is a functional liquid material with nano-sized aluminum particles as its core component. It possesses high electrical and thermal conductivity, high activity, and good dispersibility, making it widely applicable in fields requiring specific properties such as electrical conductivity, thermal conductivity, and combustion performance. Its main characteristics stem from the high surface area ratio and excellent physicochemical properties of nano-aluminum powder.

[0003] Currently, when preparing nano-aluminum powder inks, it is easy to create mixing dead zones, which affects the uniformity of dispersion. Furthermore, the temperature is not easy to control during homogenization, which to some extent affects the quality of homogenization and emulsification. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the tendency to create dead zones during mixing, which affects the uniformity of material dispersion, and the difficulty in controlling temperature during homogenization, which to some extent affects the quality of homogenization and emulsification. Therefore, this invention proposes a nano-aluminum powder ink emulsification device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A nano-aluminum powder ink emulsification device includes a dispersion tank and a closed cover on the dispersion tank. The dispersion tank is equipped with a mixing mechanism and a homogenizing mechanism, and a temperature control mechanism for adjusting its temperature is provided on the outside of the dispersion tank.

[0007] The mixing mechanism includes a motor vertically mounted on a closed cover, a main shaft coaxially connected to the motor output end and extending into the inner cavity of the dispersion tank, a stirring fan mounted on the main shaft, and a wall scraping assembly mounted on the outside of the main shaft.

[0008] The homogenizing mechanism includes a discharge pipe connected through the bottom of the dispersion tank, a return pipe connected through the upper side wall of the dispersion tank, and a high-pressure homogenizer connected through the two and disposed on one side of the dispersion tank.

[0009] Preferably, the wall scraping assembly includes a plurality of scraping rings evenly arranged against the inner wall of the dispersion tank, a plurality of connecting rods fixedly arranged between the scraping rings, a linkage bracket fixedly arranged at the upper and lower ends of the connecting rods, and a cylindrical cam fixedly mounted on the main shaft. The linkage bracket located on the upper side is provided with a linkage block corresponding to the cylindrical cam, and the linkage bracket located on the lower side is connected to the bottom wall of the dispersion tank by a plurality of elastic telescopic rods.

[0010] Preferably, the temperature control mechanism includes an insulation sleeve fitted on the side wall of the dispersion tank, with an inlet and an outlet through the insulation sleeve.

[0011] More preferably, the liquid inlet is located on the lower side of the insulation sleeve, and the liquid outlet is located on the upper side of the insulation sleeve.

[0012] More preferably, the inlet and outlet are connected to the hot water circulation pump and the cooling circulation pump via a three-way pipe, and valves are installed accordingly.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. In this utility model, by stirring the material and using a scraping ring to scrape the material adhering to the inner wall of the dispersion tank, dead corners of mixing are avoided, ensuring the uniform dispersion effect of the nano aluminum powder ink.

[0015] 2. In this utility model, the materials of the nano-aluminum powder ink are subjected to high-pressure homogenization and emulsification by a homogenization mechanism to ensure a good homogenization and emulsification effect of the nano-aluminum powder ink and improve the processing quality of the nano-aluminum powder ink.

[0016] 3. In this utility model, the temperature of the dispersion tank is controlled by a temperature control mechanism. The material is heated at the beginning of mixing to improve fluidity and reduce agglomeration. After homogenization and heating, the dispersion tank is cooled to avoid excessive temperature affecting the processing quality and to ensure good homogenization effect.

[0017] This utility model features a novel design and simple structure, ensuring good mixing and dispersion effects, reducing mixing dead zones, improving mixing uniformity, and ensuring constant temperature during homogenization, thereby improving the quality of homogenization and emulsification.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4 A nano-aluminum powder ink emulsification device includes a dispersion tank 1 and a sealing cover 11 on the dispersion tank 1. The dispersion tank 1 is equipped with a mixing mechanism 2 and a homogenizing mechanism 3. A temperature control mechanism 4 is provided on the outside of the dispersion tank 1 for adjusting its temperature. The mixing mechanism 2 is used to mix and disperse the various components of the ink, and works with the homogenizing mechanism 3 to homogenize and emulsify raw materials such as nano-aluminum powder, water, and glycerin, ensuring that the various components of the ink are evenly dispersed. The temperature control mechanism 4 is used to regulate the temperature during homogenization to ensure good homogenization quality of the nano-aluminum powder ink.

[0025] The mixing mechanism 2 includes a motor 21 vertically mounted on a closed cover 11, a main shaft 22 coaxially connected to the output end of the motor 21 and extending into the inner cavity of the dispersion tank 1, a stirring fan 23 mounted on the main shaft 22, and a wall scraping assembly mounted on the outer side of the main shaft 22. The stirring fan 23 driven by the motor 21 stirs and mixes the materials. To ensure the mixing effect, multiple stirring fans 23 can be installed, or multiple stirring rods or other devices can be used for replacement. The wall scraping assembly is used to scrape the materials adhering to the inner wall of the dispersion tank 1, avoiding mixing dead zones and ensuring uniform mixing and dispersion of each component.

[0026] The homogenization mechanism 3 includes a discharge pipe 31 connected through the bottom of the dispersion tank 1, a return pipe 32 connected through the upper side wall of the dispersion tank 1, and a high-pressure homogenizer 33 connected through both and disposed on one side of the dispersion tank 1. The high-pressure homogenizer 33 can be a plunger-type homogenizer, which draws the material from the bottom of the dispersion tank 1 into the high-pressure homogenizer 33 for homogenization, and then returns it to the dispersion tank 1 through the return pipe 32.

[0027] Based on the above technical solution, when preparing the nano-aluminum powder ink, the material is fed into the dispersion tank 1. The stirring fan 23, driven by the motor 21, stirs and mixes the material. A scraping component further scrapes the material adhering to the inner wall of the dispersion tank 1, avoiding dead zones in the mixing process and ensuring good uniform dispersion. Simultaneously, a high-pressure homogenizer 33 is used to homogenize the material under high pressure, ensuring good homogenization and emulsification quality of the nano-aluminum powder ink. During homogenization, the temperature of the dispersion tank 1 is adjusted by the temperature control mechanism 4 to ensure temperature stability during material homogenization.

[0028] In this technical solution, such as Figure 1-4As shown, the wall scraping assembly includes multiple scraping rings 25 evenly arranged against the inner wall of the dispersion tank 1, multiple connecting rods 251 fixedly arranged between the scraping rings 25, linkage brackets 26 fixedly arranged at the upper and lower ends of the connecting rods 251, and a cylindrical cam 24 fixedly mounted on the main shaft 22. The linkage bracket 26 on the upper side has a linkage block 27 corresponding to the cylindrical cam 24, and the linkage bracket 26 on the lower side is connected to the inner bottom wall of the dispersion tank 1 by multiple elastic telescopic rods 28. When the motor 21 drives the main shaft 22 to rotate, the cylindrical cam 24 rotates synchronously, pressing the linkage block 27 to drive the multiple scraping rings 25 to slide up and down, and cooperating with the elastic telescopic rods 28 to rotate, scraping the inner wall of the dispersion tank 1 and preventing the accumulation of material adhering to the inner wall of the dispersion tank 1 from affecting the material dispersion effect.

[0029] In this technical solution, such as Figure 1-4 As shown, the temperature control mechanism 4 includes an insulation sleeve 41 fitted onto the side wall of the dispersion tank 1. The insulation sleeve 41 has a liquid inlet 42 and a liquid outlet 43. The outer sides of the liquid inlet 42 and the liquid outlet 43 are connected to a hot water circulation pump and a cooling circulation pump via a three-way pipe, with corresponding valves installed. The valves switch the flow of hot or cold water into the insulation sleeve 41, thus heating or cooling the dispersion tank 1. At the start of mixing, hot water can be introduced to improve the fluidity of the material, reduce agglomeration, and enhance the mixing effect. After homogenization has begun for a period of time, the heat generated by high-pressure homogenization causes the material to heat up. Cold water can be introduced into the insulation sleeve 41 to cool the material in the dispersion tank 1, preventing excessive temperature from affecting ink quality and ensuring good material homogenization and emulsification.

[0030] In this technical solution, such as Figure 1-4 As shown, the liquid inlet 42 is located on the lower side of the insulation sleeve 41, and the liquid outlet 43 is located on the upper side of the insulation sleeve 41. This ensures that the water in the insulation sleeve 41 can flow sufficiently, thus ensuring effective temperature control of the dispersion tank 1.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
