Description

Technical Field

[0001] This utility model relates to the field of photocatalyst production technology, specifically to a photocatalyst solution production device. Background Technology

[0002] A photocatalyst is a catalyst that can promote chemical reactions under light conditions with the help of an external light source. The photocatalyst itself is not consumed in the chemical reaction; instead, it absorbs light energy to excite electrons on its surface, forming highly oxidizing free radicals, thereby catalyzing the decomposition or transformation of harmful substances.

[0003] Photocatalysts typically exist as nano-sized particles with high specific surface area and surface energy. When these particles are dispersed in a liquid, if the liquid's dispersibility is insufficient, the particles easily aggregate to form large agglomerates or precipitates. Existing photocatalyst solution production equipment generally only achieves stirring and mixing of the materials, but cannot effectively prevent the formation of precipitation and agglomerates. To address this problem, a photocatalyst solution production device needs to be proposed. Utility Model Content

[0004] In view of this, the purpose of this utility model is to propose a photocatalyst solution production device to solve the technical problem of precipitation and agglomeration of particles in the photocatalyst solution during the production process.

[0039] The cylinder 11 has a top opening structure, and a top cover 12 is provided at the top of the cylinder 11, which is fixedly connected to the cylinder 11.

[0040] Furthermore:

[0044] Furthermore:

[0045] The inner cylinder 2 is provided with multiple support rods 21 on its exterior, and the inner cylinder 2 is fixedly connected to the inner wall of the cylinder body 11 through the support rods 21.

[0046] By setting up multiple sets of support rods 21, the inner cylinder 2 is located inside the cylinder body 11.

[0047] Furthermore:

[0048] The transmission mechanism 4 includes a servo motor 41 disposed on the top of the top cover 12, and the servo motor 41 is fixedly connected to the top cover 12;

[0049] The transmission mechanism 4 also includes a transmission rod 43 and a coupling 42. The transmission rod 43 passes through the top cover 12 and is rotatably connected to it. The output shaft of the servo motor 41 is connected to the transmission rod 43 through the coupling 42.

[0050] like Figure 5 As shown, going a step further:

[0051] The transmission rod 43 includes a main rod body 44 and a secondary rod body 45. The main rod body 44 has a cavity inside. The top end of the secondary rod body 45 passes through the bottom end of the main rod body 44 and is located inside the cavity. A limiting piece 451 is provided at the top end of the secondary rod body 45. A sliding groove is provided on the limiting piece 451. The limiting piece 451 is slidably connected to the slide rail formed by the cavity inside the main rod body 44 through the sliding groove. A limiting ring 441 is provided at the bottom end of the main rod body 44. The inner diameter of the limiting ring 441 is smaller than the outer diameter of the limiting piece 451, and the inner edge surface of the limiting ring 441 contacts the outer wall of the secondary rod body 45 through a first rubber ring 46.

[0052] The stirring paddles 3 are respectively located on the outside of the main rod 44 and at the bottom of the auxiliary rod 45.

[0053] like Figure 5 As shown, going a step further:

[0054] The outer edge of the filter plate 5 is fitted with a second rubber ring 51, and the filter plate 5 is slidably and sealed to the inner wall of the inner cylinder 2 through the second rubber ring 51.

[0055] A connecting ring 52 is provided on the top of the filter plate 5, and the filter plate 5 is fixedly connected to the bottom end of the auxiliary rod 45 through the connecting ring 52.

[0056] A retaining ring 22 is provided at the bottom of the inner cylinder 2, and the inner diameter of the retaining ring 22 is smaller than the outer diameter of the filter plate 5.

[0057] The baffle ring 22 at the bottom of the inner cylinder 2 is used to prevent the filter plate 5 from falling too low and detaching from the inner wall of the inner cylinder 2.

[0058] Furthermore:

[0059] The solution production device also includes a single-shaft cylinder 6, which is located outside the cylinder 11, and the bottom of the filter plate 5 is connected to the piston rod of the single-shaft cylinder 6.

[0060] In this embodiment, before use, the photocatalyst solution is introduced into the cylinder 11 through the feed pipe 13. The photocatalyst solution flows into the inner cylinder 2 through the feed pipe 13. The transmission mechanism 4 starts to work. The output shaft of the servo motor 41 drives the transmission rod 43 to rotate through the coupling 42. Specifically, the servo motor 41 drives the main rod 44 to rotate through the coupling 42. The main rod 44 drives the auxiliary rod 45 to rotate along the axis of the inner cylinder 2 through the slide rail formed by its internal cavity. During the rotation, the stirring paddle 3 set on the main rod 44 and the auxiliary rod 45 stirs the inside of the inner cylinder 2.

[0061] During the process of stirring the photocatalyst material inside the inner cylinder 2 by the stirring paddle 3, the piston rod of the single-shaft cylinder 6 pushes the filter plate 5 to rise along the axis of the inner cylinder 2. During the rise of the filter plate 5, the photocatalyst material precipitates or agglomerated particles that have not penetrated the filter plate 5 will be pushed to the top of the inner cylinder 2. Then, in conjunction with the piston rod, the filter plate 5 will be driven to descend rapidly, so that the photocatalyst material precipitates or agglomerated particles are above the inner cylinder 2. The stirring paddle 3 will then continue to stir the inside of the inner cylinder 2 to break up the photocatalyst material precipitates or agglomerated particles.

[0062] Since the limiting ring 441 is slidably connected to the slide rail formed by the slide groove and the cavity inside the main rod 44, the rise and fall of the filter plate 5 will not affect the transmission rod 43, and the gap between the two stirring paddles 3 will not cause collision.

[0063] Finally, the photocatalyst solution, after being stirred and mixed, will be discharged from the discharge pipe 14 of the cylinder 11.
