Description

Technical Field

[0001] The utility model relates to the technical field of photocatalyst production, in particular to a photocatalyst preparation device. Background Art

[0002] Photocatalyst, also known as photocatalyst or photocatalyst material, is a general term for a class of semiconductor materials with photocatalytic function. Among them, titanium dioxide (TiO2) is the most representative photocatalyst material. When the photocatalyst is exposed to light, it can absorb light energy and generate photogenerated electron-hole pairs. The photogenerated electrons are highly active and can participate in oxidation reactions, while the photogenerated holes play an important role in reduction reactions.

[0003] However, in the process of using, the traditional photocatalyst preparation equipment only uses a motor to drive a stirring shaft to rotate in the equipment, which has a poor stirring effect on the raw materials. During use, the contact area with the stirring structure is small. The photocatalyst needs to be heated during preparation, and it is inconvenient to adjust the temperature of the photocatalyst raw materials that need to be stirred at a specific temperature. Therefore, the utility model proposes a photocatalyst preparation device to solve the above problems. Utility Model Content

[0005] In order to achieve the purpose of the utility model, the utility model is implemented through the following technical solutions:

[0006] A photocatalyst preparation device comprises a tank body, a liquid infusion pipe, a feed pipe and a liquid outlet pipe, wherein the top of the tank body is connected with the liquid infusion pipe and the feed pipe, the top of the feed pipe is hinged with an end cap, the bottom of the tank body is connected with the liquid outlet pipe, and a stirring mechanism is arranged inside the tank body;

[0007] The stirring mechanism includes a stirring shaft, stirring blades, a support rod and an arc plate. The stirring shaft is rotatably connected to the inside of the tank body, and multiple groups of stirring blades are fixedly connected to the outside of the stirring shaft. The bottom end of the stirring shaft is symmetrically fixedly connected to the support rod, and arc plates are symmetrically fixedly connected on both sides of the support rod with the stirring shaft as the center.

[0008] Furthermore, a homogenizing shaft is rotatably connected to one side of the top of the feed pipe, and the center of the homogenizing shaft is equidistant from the center of the support rod or the stirring shaft, and a rotating mechanism matching the homogenizing shaft and the stirring shaft is provided at the top of the tank body.

[0009] Furthermore, the rotating mechanism comprises a motor, the top of the tank body is fixedly connected with a fixing frame, the top of the fixing frame is equipped with a motor, and the output end of the motor is fixedly connected with the top end of the stirring shaft through a coupling.

[0010] Furthermore, the rotating mechanism also includes a driving gear and a driven gear, the top of the stirring shaft is fixedly connected with the driving gear, the top of the homogenizing shaft is fixedly connected with the driven gear, and the driven gear is meshed with the outer wall of the homogenizing shaft.

[0011] Furthermore, both the driving gear and the driven gear are cylindrical gears.

[0012] Furthermore, an outer side of the support rod is fixedly connected with an outer scraper, the top and bottom ends of the outer scraper are symmetrically provided with arc edges, and one side of the outer scraper is closely connected with the inner wall of the tank body.

[0013] Furthermore, a bottom scraper is fixedly connected to the bottom end of the support rod, the bottom end of the tank body is configured as a bucket-shaped structure, and the bottom end of the bottom scraper is closely connected to the inner wall of the bottom end of the tank body.

[0014] Furthermore, an electric heater is installed on the top of the feed pipe, and an electric heating rod is fixedly installed on the bottom end of the electric heater, and the length of the center of the electric heating rod is equal to the length of the center of the support rod or the center of the stirring shaft.

[0015] Furthermore, the bottom of the tank body is provided with supporting legs, and the supporting legs are arranged around the bottom of the tank body.

[0016] Furthermore, the infusion tube is arranged perpendicularly to the axis of the tank body.

[0017] The beneficial effects of the utility model are:

[0018] 1. The motor can drive the stirring shaft to rotate inside the tank body. The stirring shaft stirs the base liquid and crystal powder inside the tank body through the stirring blades on the outside to mix them. The stirring shaft drives the arc plate to rotate inside the tank body through the bracket rod, so as to stir the base liquid and crystal powder inside the tank body up and down to make their mixing effect better. The motor drives the homogenizing shaft to rotate inside the tank body through the driving gear and the driven gear, and fully breaks up the base liquid into small droplets, which helps the base liquid to fully wrap the crystal powder to form a photocatalyst solution.

[0019] 2. Since the center distances of the homogenizing shaft and the stirring shaft are equal, the two can produce similar mechanical effects when rotating, thereby helping to improve the mixing uniformity of the materials in the tank.

[0020] 3. The motor is directly connected to the stirring shaft through a coupling, which reduces the intermediate transmission components and simplifies the transmission structure, which not only reduces the manufacturing cost, but also improves the transmission efficiency and reduces the energy loss. The fixed frame fixes the motor on the top of the tank, which increases the stability. Even if there is a large vibration and impact during the stirring process, the motor can maintain stable operation, ensuring the continuity and stability of the stirring process.

[0021] 4. Due to the meshing relationship between the driving gear and the driven gear, when the stirring shaft rotates, the homogenizing shaft will also rotate synchronously. This synchronous drive ensures the coordination of the stirring and homogenizing processes, allowing the two to cooperate with each other and improve the overall stirring and homogenizing effect.

[0022] 5. As the support rod rotates, the outer scraper can move close to the inner wall of the tank, effectively scraping off the material attached to the tank wall and bringing it back into the mixing area, which ensures uniform mixing of the material in the tank and avoids the accumulation of materials on the tank wall, thereby improving the mixing efficiency. The arc design of the outer scraper can better adapt to the curvature of the tank, making the contact between the scraper and the tank wall closer, reducing the residual material on the tank wall. This helps to reduce waste and improve the utilization of materials.

[0023] 6. The bottom scraper can move close to the bottom inner wall of the tank as the support rod rotates, effectively scraping up the materials accumulated at the bottom of the tank and bringing them back into the mixing area, avoiding the residue of materials at the bottom. The bucket-shaped structure design of the tank allows the materials to gradually gather toward the center during the mixing process, which is convenient for discharge. When the mixing is completed, the materials will naturally flow to the center of the bucket-shaped structure. At this time, the rotation of the bottom scraper can further push the materials to the outlet, thereby optimizing the material discharge process.

[0024] 7. The center of the electric heating rod is equal to the center of the support rod or the stirring shaft, which ensures that the material in the feed pipe can be heated evenly, helps prevent local overheating or underheating of the material during the heating process, thereby ensuring the quality and performance of the material.
