Description

Technical Field

[0002] Photocatalytic paint is an environmentally friendly functional paint that is composited with photocatalytic materials. It has catalytic reaction function when irradiated with light of a certain wavelength. This paint can use the energy of a specific wavelength of the light source to produce a photocatalytic effect, exciting the oxygen and water molecules attached to the surface of the material to generate super-active OH and O2 free ion radicals. These free radicals can decompose almost all organic substances and some inorganic substances that are harmful to the human body or the environment, and eventually convert them into carbon dioxide and water.

[0003] The production process of photocatalytic coatings mainly includes the following steps: material preparation, mixing preparation, material screening, color configuration, grinding processing, filling and packaging storage; during the grinding process, the coating is usually ground by two grinding discs rotating relative to each other. As the grinding proceeds, the coating between the two grinding discs gradually decreases, and the coating moves to the edge as the grinding discs rotate, gradually moving into the gaps of the grinding discs, resulting in insufficient grinding of the coating and unsatisfactory results.

The top is rotatably connected, the lower end of the grinding rod shaft 310 passes through the upper feed bin 110 and extends to the interior of the lower grinding silo 120, the upper grinding disc 320 is arranged inside the grinding rod shaft 310 and cooperates with the upper surface of the grinding mesh disc 140 to grind the paint; it also includes a grinding motor 400, a grinding cylinder part 420, a rotating drive component 600 and a plurality of radial pushing components 500, the grinding motor 400 is arranged at the top of the outer frame 200 and the output end of the grinding motor 400 is connected to the upper grinding disc 320 through a gear transmission pair 410, the grinding cylinder part 420 is fixed on the outer frame 200 and the grinding cylinder part 420 is connected to the grinding rod shaft 310; a plurality of radial pushing components 500 is circumferentially distributed on the outside of the lower grinding silo 120 and the radial pushing component 500 includes a hollow arc-shaped push plate 510, a hollow push rod 520 and a pushing air guide 530. The hollow arc-shaped push plate 510 is located inside the lower grinding silo 120 and is on the upper surface of the grinding mesh disk 140. When multiple hollow arc-shaped push plates 510 are located on the inner wall of the lower grinding silo 120, they form a circle. A central blowing hole 511 is opened on the inner side of the hollow arc-shaped push plate 510 and side air holes 512 are provided on both ends of the hollow arc-shaped push plate 510. The hollow push rod 520 passes through the side wall of the lower grinding silo 120, and one end of the hollow push rod 520 is connected to the hollow arc-shaped push plate 510 And the other end is connected to the pushing air guide part 530 arranged on the outer wall of the lower grinding silo 120. The rotating driving component 600 is arranged on the outside of the lower grinding silo 120 and connected to the outer frame 200. The rotating driving component 600 is connected to multiple pushing air guide parts 530 and the rotating driving component 600 can act on the pushing air guide part 530 alternately by rotating. Under the action of the rotating driving component 600, the pushing air guide part 530 can push and pull the hollow push rod 520, and when the hollow arc-shaped push plate 510 moves toward the center of the grinding mesh disk 140, the pushing air guide part 530 introduces airflow into the inside of the hollow arc-shaped push plate 510 through the hollow push rod 520.

[0032] In the embodiment of the present invention, before the paint is introduced into the grinding box 100, the grinding cylinder part 420 works and drives the rotating grinding component 300 to move upward until the upper grinding disc 320 is on the upper side of the upper feed bin 110, and the paint falls from the upper feed bin 110 to the upper surface of the grinding mesh disc 140. The grinding cylinder part 420 drives the rotating grinding component 300 to move downward, and the lower surface of the upper grinding disc 320 contacts the paint on the grinding mesh disc 140 and applies downward pressure thereto; the grinding motor 400 starts to work and the grinding motor 400 drives the grinding rod shaft 310 and the upper grinding disc 320 to rotate through the gear transmission pair 410, and the upper grinding disc 320 is relative to the grinding mesh disc 1 40 rotates and grinds the paint between the two. After grinding, the paint that meets the requirements falls through the sieve holes of the grinding mesh disk 140 and is then discharged from the discharge port at the bottom of the lower grinding silo 120; some of the paint that does not meet the requirements gradually moves to the edge of the grinding mesh disk 140. As the paint between the grinding mesh disk 140 and the upper grinding disk 320 gradually decreases, when the grinding is insufficient, the grinding cylinder part 420 drives the rotating grinding component 300 to move upward until the lower surface of the upper grinding disk 320 is higher than the upper end of the hollow arc-shaped push plate 510; at this time, the rotating drive component 600 starts to work and acts on multiple circumferentially distributed in the lower grinding silo in a rotating manner. The pushing air guide part 530 on the outside of 120, the pushing air guide part 530 drives the hollow push rod 520 to move toward the inside of the lower grinding silo 120 under the action of the rotating driving component 600, and the hollow push rod 520 pushes the corresponding hollow arc-shaped push plate 510 to move toward the center of the grinding mesh disk 140. Multiple hollow arc-shaped push plates 510 move toward the center of the grinding mesh disk 140 in turn, so that the paint at the edge of the grinding mesh disk 140 is pushed to the center of the grinding mesh disk 140. At the same time, when the pushing air guide part 530 pushes the hollow push rod 520, it also introduces airflow into the hollow arc-shaped push plate 510 through the hollow push rod 520, and the airflow passes through the central blowing hole 511 and the two The air flows out from the side air holes 512 of the group, and the air flows out from the central air holes 511 toward the center of the grinding mesh disk 140 and enables the coating to move fully. The air flows out from the side air holes 512 can act on the coating on both sides of the path of the hollow arc-shaped pusher plate 510, so that the coating moves to the opposite position of the adjacent hollow arc-shaped pusher plate 510, thereby avoiding the coating accumulation on the side of the path of the hollow arc-shaped pusher plate 510, which causes the coating to fall back to the return path after the hollow arc-shaped pusher plate 510 passes. The coating gathered at the center of the grinding mesh disk 140 can be ground again by the grinding mesh disk 140 and the upper grinding disk 320, so that the coating can be ground fully and the grinding effect is guaranteed.
