Description

Technical Field

[0001] This utility model relates to the field of graphene technology, specifically to a graphene acid washing device. Background Technology

[0002] Graphene is a novel material with a single-layer sheet-like structure composed of carbon atoms. It is a two-dimensional material, only one atom thick, consisting of a hexagonal honeycomb lattice of carbon atoms arranged in sp2 hybrid orbitals. Graphene is the thinnest and strongest known nanomaterial. It is almost completely transparent, absorbing only 2.3% of light; its thermal conductivity is as high as 5300 W / m·K, higher than carbon nanotubes and diamond; its electron mobility at room temperature exceeds 15000 cm² / V·s, higher than carbon nanotubes or silicon crystals; and its resistivity is only about 10⁻⁸ Ω·cm, lower than copper or silver, making it the material with the lowest resistivity in the world. Due to its extremely low resistivity and extremely fast electron migration, it is expected to be used to develop thinner, faster-conducting next-generation electronic components or transistors. Because of these special properties, graphene is suitable for manufacturing transparent touch screens, light panels, and even solar cells, leading to unprecedented attention and research in graphene preparation and applications in recent years.

[0003] Patent specification CN204369572U discloses a graphene pickling device, including a frame, a conveyor belt on the frame, and a pickling chamber covering the conveyor belt. The pickling chamber consists of a spraying unit and an immersion unit. The spraying unit is equipped with a spray pipe at the top, and the spray pipe has multiple downward spray nozzles at intervals, with nozzles installed on the spray nozzles. The immersion unit is equipped with a rinsing pipe at the top. Both the spraying unit and the immersion unit are equipped with acid collection devices, and the collection devices are connected to a water pump and a filter tank through pipes, forming their own circulation.

[0004] However, during the implementation of the relevant technology, the following problems were found in the above technical solution: In the process of using the above device, the preparation of graphene generally involves growing graphene on a metal substrate and then removing the metal substrate to obtain graphene. However, during the process of removing the metal substrate, when reusing the pickling solution after pickling, the pickling solution is not effectively filtered, resulting in the pickling solution still containing a large number of impurities when entering the pickling device again. This will affect the quality of the pickling solution and thus affect the pickling effect of the pickling solution on graphene. Furthermore, the filter residue is not treated when filtering the pickling solution, causing the filter residue to accumulate in the device. This will affect the pickling effect during the re-pickling of graphene. Therefore, further improvements are needed. Utility Model Content

[0005] This invention proposes a graphene pickling device, which solves the problems in related technologies where it is inconvenient to effectively filter the pickling solution after pickling for reuse and to effectively treat the filter residue.

[0006] The technical solution of this utility model is as follows:

[0007] A graphene pickling device includes a pickling tank with a feed pipe and a liquid inlet pipe connected through its upper end. Pickling components are arranged on the inside and outer surfaces of the pickling tank. Each pickling component includes a spray pipe uniformly and fixedly connected to the lower end of the top side inside the pickling tank. A filter block is fixedly connected to the center of the inside of the pickling tank. A conveying component is provided on the outer surface of the pickling tank for re-introducing the filtered, compliant pickling solution into the tank. The conveying component includes a conveying pipe on the outer surface of the pickling tank, a fixed ring fixedly connected to the outer surface of the conveying pipe, and a sliding ring slidably connected to the outer surface of the conveying pipe. A first magnetic suction plate is fixedly connected to the inner wall of the sliding ring.

[0008] Preferably, the spray pipe passes through the interior of the pickling tank and is connected to the liquid inlet pipe.

[0009] Preferably, a connecting rod is fixedly connected to one side of the fixing ring, and one end of the connecting rod is fixedly connected to the side of the pickling tank.

[0010] Preferably, the conveying component includes an inlet pipe fixedly connected to the lower end of the conveying pipe, an outlet pipe fixedly connected to the upper end of the conveying pipe, a water pump fixedly installed on the side wall of the inlet pipe inside the conveying pipe, a filter disc fixedly connected to the inner wall of the central part of the conveying pipe, a cleaning component slidably installed at the inlet pipe inside the conveying pipe, and a first storage component and a second storage component connected to the corner of the lower end of the conveying pipe.

[0011] Preferably, the water inlet pipe is connected to the lower end of the pickling tank, and the water outlet pipe is connected to the upper end of the pickling tank.

[0012] Preferably, both the first and second storage components are equipped with valves.

[0013] Preferably, the cleaning component includes an auxiliary ring slidably connected inside the delivery pipe, a first connecting block is fixedly connected to one side of the auxiliary ring, a second connecting block is fixedly connected to the other side of the auxiliary ring, a second magnetic suction plate is fixedly connected to the outer surface of the auxiliary ring, a first cleaning filter block is fixedly connected to one end of the first connecting block, and a second cleaning filter block is fixedly connected to one end of the second connecting block.

[0014] Preferably, the second magnetic plate is magnetically connected to the first magnetic plate, the first cleaning filter block is attached to the inner wall of the conveying pipe, and the second cleaning filter block is also attached to the inner wall of the conveying pipe.

[0015] The working principle and beneficial effects of this utility model are as follows:

[0016] 1. This utility model allows the pickling solution after pickling to enter the conveying pipe through the inlet pipe. At this time, the water pump can be controlled to drive the pickling solution in the conveying pipe to flow. The pickling solution is filtered through the filter plate, causing the filter residue in the conveying pipe to fall into the horizontally placed pipe at the lower end of the conveying pipe. The pickling solution that meets the specifications after filtration flows upward through the conveying pipe to the outlet pipe and enters the interior of the pickling tank for reuse. This solves the problem of it being inconvenient to effectively filter the pickling solution after pickling and reuse it.

[0017] 2. This utility model, with the spray pipe closed and the valve open, allows the operator to pull a moving ring along the outer surface of the conveying pipe. Under the magnetic action of the second and first magnetic plates, the moving ring synchronously drives the auxiliary ring to move. When the moving ring is moved to the side of the horizontally placed pipe at the lower end of the conveying pipe near the inlet pipe, the first cleaning filter block is pushed above the first storage component. At this point, impurities are no longer blocked by the valve and are pushed into the interior of the first storage component by gravity. When the moving ring is moved to the side of the horizontally placed pipe at the lower end of the conveying pipe away from the inlet pipe, the second cleaning filter block pushes the impurities accumulated in the conveying pipe into the interior of the second storage component. Then, the first and second storage components are removed, thus completely removing the impurities accumulated in the conveying pipe and solving the problem of inconvenient effective treatment of filter residue.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0026] like Figure 1 As shown in the figure, this embodiment proposes a graphene pickling device, including a pickling tank 1, with a feed pipe 11 and a liquid inlet pipe 12 connected through the upper end of the pickling tank 1, and pickling components 2 provided on the inner and outer surfaces of the pickling tank 1.

[0027] like Figure 2 As shown, the pickling assembly 2 includes a spray pipe 22 uniformly and fixedly connected to the lower end of the top side inside the pickling tank 1. A filter block 23 is fixedly connected to the center of the inside of the pickling tank 1. The spray pipe 22 passes through the inside of the pickling tank 1 and is connected to the liquid inlet pipe 12. The filter block 23 is used to separate the graphene from the pickling solution. The spray pipe 22 is used to spray and rinse the graphene stored on the upper end of the filter block 23 to complete the pickling of the graphene.

[0028] like Figure 1 As shown, a fixing ring 21 is fixedly connected to the outer surface of the conveying pipe 251. A connecting rod 211 is fixedly connected to one side of the fixing ring 21. One end of the connecting rod 211 is fixedly connected to the side of the pickling tank 1. The connecting rod 211 and the fixing ring 21 cooperate with each other to fix the conveying pipe 251 to the side of the pickling tank 1.

[0029] like Figure 5As shown, a conveying component 25 is provided on the outer surface of the pickling tank 1 for re-introducing the filtered, compliant pickling solution into the interior of the pickling tank 1. The conveying component 25 includes a conveying pipe 251 disposed on the outer surface of the pickling tank 1, an inlet pipe 2511 fixedly connected to the lower end of the conveying pipe 251, an outlet pipe 2512 fixedly connected to the upper end of the conveying pipe 251, a water pump 2513 fixedly disposed on the side wall of the inlet pipe 2511 inside the conveying pipe 251, a filter disc 2514 fixedly connected to the inner wall of the central part of the conveying pipe 251, a cleaning component 2515 slidably disposed at the inlet pipe 2511 inside the conveying pipe 251, and a first storage component 251 connected to the corner of the lower end of the conveying pipe 251. 6. The first storage unit 2516 and the second storage unit 2517 are connected by an inlet pipe 2511 to the lower end of the pickling tank 1 and an outlet pipe 2512 to the upper end of the pickling tank 1. Both the first storage unit 2516 and the second storage unit 2517 are equipped with valves 25161. A water pump 2513 is used to provide power to the liquid in the conveying pipe 251, so that the pickling liquid can flow from the inlet pipe 2511 along the conveying pipe 251 to the outlet pipe 2512. A filter plate 2514 is used to further filter the pickling liquid in the conveying pipe 251 to prevent impurities in the pickling liquid from continuously flowing along the conveying pipe 251 to the outlet pipe 2512. The first storage unit 2516 and the second storage unit 2517 are used to collect impurities in the pickling liquid in the conveying pipe 251.

[0030] like Figure 3 As shown, a movable ring 24 is slidably connected to the outer surface of the conveying pipe 251, and a first magnetic suction plate 241 is fixedly connected to the inner wall of the movable ring 24.

[0031] like Figure 4As shown, the cleaning component 2515 includes an auxiliary ring 25151 slidably connected inside the conveying pipe 251. A first connecting block 25152 is fixedly connected to one side of the auxiliary ring 25151, and a second connecting block 25153 is fixedly connected to the other side of the auxiliary ring 25151. A second magnetic plate 251511 is fixedly connected to the outer surface of the auxiliary ring 25151. A first cleaning filter block 251521 is fixedly connected to one end of the first connecting block 25152, and a second cleaning filter block 251531 is fixedly connected to one end of the second connecting block 25153. The second magnetic plate 251511 is magnetically connected to the first magnetic plate 241. The first cleaning filter block 251521 is attached to the inner wall of the conveying pipe 251, and the second cleaning filter block 251531 is also attached to the conveying pipe 251. Under the magnetic action of the second magnetic suction plate 251511 and the first magnetic suction plate 241, the moving ring 24 moves outside the conveying pipe 251, which can synchronously drive the auxiliary ring 25151 inside the conveying pipe 251 to move. The first cleaning filter block 251521 and the second cleaning filter block 251531 are used to push the impurities accumulated in the conveying pipe 251 to the first storage container 2516 and the second storage container 2517. The valve 25161 is used to prevent the pickling liquid in the conveying pipe 251 from entering the interior of the first storage container 2516 and the second storage container 2517 when it is closed. When the valve 25161 is open, the impurities accumulated on the inner wall of the conveying pipe 251 can enter the interior of the first storage container 2516 and the second storage container 2517 through the valve 25161.

[0032] The working principle and usage instructions of this utility model are as follows: When it is necessary to pickle graphene, the operator first needs to pour the graphene into the pickling tank 1 through the feed pipe 11. The graphene will accumulate on the upper end of the filter block 23. Then, the spray pipe 22 can be controlled to spray pickling liquid onto the graphene accumulated on the upper end of the filter block 23 to complete the pickling of the graphene. After the pickling is completed, the graphene is filtered by the filter block 23. That is, the graphene still accumulates on the upper end of the filter block 23, while the pickling liquid after pickling can flow freely through the filter block 23 to complete the filtration of the graphene.

[0033] After pickling, the pickling solution enters the conveying pipe 251 through the inlet pipe 2511. At this time, the water pump 2513 can be controlled to drive the pickling solution in the conveying pipe 251 to flow. The pickling solution is filtered through the filter plate 2514, causing the filter residue in the conveying pipe 251 to fall into the horizontally placed pipe at the lower end of the conveying pipe 251. The pickling solution that meets the specifications after filtration flows upward through the conveying pipe 251 to the outlet pipe 2512 and enters the interior of the pickling tank 1 for reuse.

[0034] When it is necessary to remove impurities accumulated in the horizontal pipe at the lower end of the conveying pipe 251, with the spray pipe 22 closed and the valve 25161 open, the operator pulls the moving ring 24 to slide along the outer surface of the conveying pipe 251. Under the magnetic action of the second magnetic plate 251511 and the first magnetic plate 241, the moving ring 24 will synchronously drive the auxiliary ring 25151 to move. When the moving ring 24 is moved to the side of the horizontal pipe at the lower end of the conveying pipe 251 near the water inlet pipe 2511, the first cleaning filter block 251521 is pushed above the first storage component 2516. At this time, the impurities are removed. No longer blocked by valve 25161, the impurities are pushed into the first storage container 2516 by gravity under the action of the first cleaning filter block 251521. When the moving ring 24 is moved to the side of the horizontal pipeline at the lower end of the conveying pipe 251 away from the inlet pipe 2511, the second cleaning filter block 251531 will push the impurities accumulated in the conveying pipe 251 into the second storage container 2517. Then, the first storage container 2516 and the second storage container 2517 can be removed, and the impurities accumulated in the conveying pipe 251 can be completely removed. Because the first storage container 2516 is located at the corner on one side of the lower end of the conveying pipe 251, that is, the conveying... A drop trough is provided at the corner of the lower end of the conveying pipe 251, which is connected to the first storage unit 2516. When the device is not in use, that is, when there is no pickling liquid flowing inside the conveying pipe 251, the first cleaning filter block 251521 is pushed to the corner of the lower end of the conveying pipe 251 by the auxiliary ring 25151, that is, pushed above the drop trough on the lower end of the conveying pipe 251. At this time, the impurities accumulated inside the conveying pipe 251 will be pushed to this position by the first cleaning filter block 251521. Due to the existence of the drop trough, the impurities are eliminated by the supporting force on the inner wall of the conveying pipe 251. Impurities will continue to fall along the drop chute under the action of gravity, and thus enter the interior of the first storage unit 2516 through valve 25161. The second cleaning filter block 251531 pushes the impurities into the second storage unit 2517 in the same way. Both the first cleaning filter block 251521 and the second cleaning filter block 251531 are used to clean the impurities on the inner wall of the conveying pipe 251. Under the action of gravity, the impurities will accumulate at the lower end of the inner wall of the conveying pipe 251. As the first cleaning filter block 251521 moves on the inner wall of the conveying pipe 251, it will push the impurities in the conveying pipe 251.

[0035] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
