Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.
[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0031] like Figure 1 and Figure 2As shown, this utility model discloses a copper-based nanocatalyst production device, including a base 1, on which a support 3 in the shape of a "door" is provided. The support 3 includes two parallel end plates 32, and a support plate 31 perpendicular to them is connected between the two end plates 32.
[0032] One end of the bottom of the support plate 31 is hinged to the base 1, and the other end of the bottom of the support plate 31 is provided with a pad 2 that cooperates with the base 1. The bottom of the support plate 31 is also hinged to the base 1 with a hydraulic cylinder 4. The extension and retraction of the hydraulic cylinder 4 controls the swing of the support 3, which can make the support plate 31 of the support 3 swing to a horizontal state or a near-vertical state. When the support plate 31 is horizontal, the pad 2 at the bottom of the support plate 31 contacts the base 1 and supports it.
[0033] The support plate 31 is provided with three baffles 9 arranged parallel to the end plate 32. The three baffles 9 divide the support 3 into four areas between the two end plates 32. The four areas are respectively provided with a primary grinding cylinder 5, a secondary grinding cylinder 6, a tertiary grinding cylinder 7, and a material cylinder 8. In the direction away from the pad block 2, the primary grinding cylinder 5, the secondary grinding cylinder 6, the tertiary grinding cylinder 7, and the material cylinder 8 are arranged in sequence and are in a coaxial state. The primary grinding cylinder 5, the secondary grinding cylinder 6, and the tertiary grinding cylinder 7 are all rotatably arranged and can rotate on the support 3. The material cylinder 8 is fixed on the support 3. The two ends of the primary grinding cylinder 5 are rotatably connected to the corresponding baffles 9 and the end plate 32, respectively. The two ends of the secondary grinding cylinder 6 and the tertiary grinding cylinder 7 are rotatably connected to the two corresponding baffles 9. One end of the material cylinder 8 is fixedly connected to the end plate 32, and the other end is rotatably connected to the corresponding baffle 9.
[0034] Each of the primary grinding cylinder 5, secondary grinding cylinder 6, tertiary grinding cylinder 7, and material cylinder 8 is equipped with a material gate that can be sealed or opened. A drive ring 10 is coaxially mounted on the outer wall of each of the primary, secondary, and tertiary grinding cylinders 5 and 6. A drive motor 11 is correspondingly mounted on the support plate 31. A drive wheel, which is also connected to the drive ring 10, is driven by the drive motor 11. The drive ring 10 can be an outer ring gear structure, and the drive wheel can be a corresponding gear structure. The drive motor 11 drives the corresponding primary, secondary, or tertiary grinding cylinder 7 to rotate. Each of the primary, secondary, and tertiary grinding cylinders 5 and 6 is driven by a different drive motor 11, and their speeds can be controlled independently.
[0035] The baffle 9 has a through groove 16. The two ends of the first-stage grinding cylinder 5 are rotatably and sealed to the corresponding end plate 32 and the groove 16 on the corresponding baffle 9. The two ends of the second-stage grinding cylinder 6 and the third-stage grinding cylinder 7 are rotatably and sealed to the groove 16 on the corresponding two baffles 9. The material cylinder 8 is rotatably and sealed to the groove 16 on the corresponding baffle 9, so that the internal spaces of the first-stage grinding cylinder 5, the second-stage grinding cylinder 6, the third-stage grinding cylinder 7 and the material cylinder 8 are connected and sealed to the outside.
[0036] In the direction away from the pad block 2, the three baffles 9 are arranged in the cylindrical groove 16 with a first-stage screen 12, a second-stage screen, and a third-stage screen in sequence. The screen hole size of the first-stage screen 12, the second-stage screen, and the third-stage screen gradually decreases and they can rotate on the inner wall of the cylindrical groove 16.
[0037] The first-stage grinding cylinder 5, the second-stage grinding cylinder 6, and the third-stage grinding cylinder 7 are respectively equipped with a number of first grinding balls, second grinding balls, and third grinding balls. The diameter of the first grinding balls, second grinding balls, and third grinding balls decreases in sequence. The first grinding ball can be a stainless steel ball, the second grinding ball can be a zirconia ball, and the third grinding ball can be a pure copper ball. The inner wall of the rotating connection between the primary grinding cylinder 5 and the groove 16 of the baffle 9 is provided with a primary barrier 13. The inner walls of both ends of the secondary grinding cylinder 6 are provided with secondary barrier 15. The inner walls of both ends of the tertiary grinding cylinder 7 are provided with tertiary barrier. The mesh size of the primary barrier 13, secondary barrier 15 and tertiary barrier gradually decreases and the mesh size is matched with the first grinding ball, the second grinding ball and the third grinding ball respectively. That is, their size is slightly smaller than the corresponding grinding ball size, so the grinding ball cannot pass through the barrier. In addition, the mesh size of the primary barrier 13, secondary barrier 15 and tertiary barrier is larger than the sieve size of the primary screen 12, the secondary screen and the tertiary screen respectively. That is, the function of the barrier is to prevent the grinding ball from entering other grinding cylinders, and the barrier will not block the material with qualified particle size after grinding.
[0038] The primary barrier 13, secondary barrier 15, and tertiary barrier are non-planar structures, and they are regular or irregular concave-convex structures. Specifically, the primary barrier 13, secondary barrier 15, and tertiary barrier can be formed by several regular triangular pyramid or regular square pyramid-shaped grooves closely connected together, with their cones facing outwards from the grinding cylinder to avoid their cones contacting the grinding balls. The regular triangular pyramid or regular square pyramid-shaped grooves are welded together from three or four perforated plates of corresponding shapes.
[0039] Multiple connecting rods 14 connect the edge of the primary screen 12 to the edge of the primary barrier 13 on its side, the edge of the secondary screen to the edge of the secondary barrier 15 on its side, and the edge of the tertiary screen to the edge of the tertiary barrier on its side. These connecting rods 14 are evenly spaced circumferentially, connecting the primary screen 12 and the primary barrier 13, the secondary screen and the secondary barrier 15, and the tertiary screen and the tertiary barrier to form an integrated structure. Because the barrier has a concave-convex structure, when the barrier rotates with the grinding cylinder, the grinding balls on the barrier will bounce, causing the barrier to vibrate. Through the connecting rods 14, the barrier transmits this vibration to the corresponding screen, causing the screen to vibrate. This vibration of the barrier and the screen facilitates the passage of materials of the correct particle size through the barrier and screen into the next grinding cylinder 5 or material cylinder 8.
[0040] Copper oxide and zinc oxide enter the primary grinding cylinder 5. The drive motor 11 of the primary grinding cylinder 5 drives it to rotate to achieve coarse grinding. After coarse grinding for a period of time, the hydraulic cylinder 4 drives the support 3 to swing to a vertical position. The material with qualified particle size passes through the primary screen 13, the primary screen 12 and the secondary screen 15 in sequence and enters the secondary grinding cylinder 6. During this process, the first grinding ball rolls on the primary screen 13. Since the primary screen 13 is a non-planar structure, the first grinding ball jumps on the primary screen 13, causing the primary screen 13 to vibrate. The connecting rod 14 causes the primary screen 12 to vibrate as well, which is beneficial for screening and filtering the material. The hydraulic cylinder 4 then drives the support 3 to be horizontal or vertical again, repeating the above process until the material in the primary grinding cylinder 5 is ground and enters the secondary grinding cylinder 6. The primary grinding cylinder 5 stops rotating, and the secondary grinding cylinder 6 rotates to perform intermediate grinding.
[0041] The working process of the secondary grinding cylinder 6 is similar to that of the primary grinding cylinder 5, until the material in the secondary grinding cylinder 6 is ground and refined. The material passes through the secondary screen 15, the secondary screen, and the tertiary screen and enters the tertiary grinding cylinder 7. Then the secondary grinding cylinder 6 stops operating, and the tertiary grinding cylinder 7 rotates to perform fine grinding. The working process of the tertiary grinding cylinder 7 is also similar to that of the primary grinding cylinder 5, until the material in the tertiary grinding cylinder 7 is finely ground and enters the material cylinder 8.
[0042] This invention enables three-stage grinding of materials, all of which are carried out in the same equipment. There is no need to transfer materials between the multiple grinding stages, which greatly improves grinding efficiency. By utilizing the jumping of grinding balls on an uneven screen, the screen vibrates, enabling material screening and filtration without adding a vibration mechanism or other components, thus improving the efficiency of screening out qualified materials.
[0043] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
