Description

Technical Field

[0001] This utility model relates to the field of graphite carbon nanotube processing technology, specifically to a water washing device for graphite carbon nanotubes. Background Technology

[0002] Graphite carbon nanotubes, commonly referred to simply as carbon nanotubes, are carbon tubes formed by rolling up layers of graphite carbon atoms. Their diameter is generally a few nanometers to tens of nanometers, and the wall thickness is only a few nanometers. They resemble hollow cylindrical "cage-like tubes" made of rolled wire mesh. Carbon nanotubes have extremely high strength and toughness. Their strength is 100 times that of steel of the same volume, while their weight is only 1 / 6 to 1 / 7 of that of steel. Carbon nanotubes have excellent thermal conductivity and can be used to prepare highly efficient heat-conducting materials.

[0003] Carbon nanotubes, as a type of nanomaterial, have a large specific surface area, allowing them to adsorb a large number of ions, similar to activated carbon. These ions may be impurities introduced during preparation or processing, potentially negatively impacting the performance and applications of carbon nanotubes. Water washing can utilize the properties of deionized water to remove these impurity ions, thereby improving the purity of carbon nanotubes. However, most current water washing devices can only perform simple rinsing or soaking. This single cleaning method may not be sufficient to remove dirt and impurities from the surface of graphite carbon nanotubes, thus affecting the cleaning effect. During water washing, graphite carbon nanotubes are mostly in a static state, lacking necessary agitation or movement. This static state can easily lead to insufficient contact between the cleaning solution and the surface of the graphite carbon nanotubes, making it difficult to effectively wash away dirt and impurities.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-6 As shown, a water washing device for graphite carbon nanotubes includes a washing tank 1. A mounting frame 2 is fixed to the rear side of the washing tank 1. Cylinders 3 are installed on both the left and right sides of the top of the mounting frame 2, and the output shaft of the cylinders 3 passes through the mounting frame 2 and is fixed to a lifting frame 4. Connecting plates 5 are fixed to the left and right sides of the front side of the lifting frame 4. A placement box 6 is provided below the connecting plate 5, and a shielding rail 7 is fixed to the top of the placement box 6. Aeration pumps 8 are fixed to the lower left and right sides of the washing tank 1, and one side of the aeration pump 8 is connected to a passageway. The air pipe 9 has one end that extends into the interior of the washing tank 1 and is fixedly connected to the washing tank 1. The top of the air pipe 9 is connected to multiple aeration discs 10. Mounting platforms 11 are bolted to the upper left and right sides of the inner wall of the washing tank 1. A reciprocating structure 12 is movably connected to the surface of the mounting platform 11. A connecting strip 13 is fixed below the reciprocating structure 12. A swing plate 14 is fixed to the bottom of the connecting strip 13. Positioning blocks 15 that cooperate with the swing plate 14 are fixed to the front and back of the left and right sides of the bottom of the placement box 6.

[0024] The reciprocating structure 12 includes a motor 121, a movable plate 122, a moving frame 123, and a connecting shaft 124. The motor 121 is fixed to the top of the mounting platform 11, and the output shaft of the motor 121 passes through the mounting platform 11 and is fixedly connected to one side of the movable plate 122. The moving frame 123 is located below the mounting platform 11. The connecting shaft 124 is fixed to one side of the bottom of the movable plate 122, and the connecting shaft 124 passes through the moving frame 123 and is slidably connected to the inner wall of the moving frame 123. The top of the connecting bar 13 is fixedly connected to the bottom of the moving frame 123. Guide frames 17 are fixed on both the front and rear sides of the mounting platform 11, and guide rods 18 are fixed on the left and right sides between the guide frames 17. Guide sleeves 19 are fixed on both the left and right sides of the movable frame 123, and guide rods 18 pass through the guide sleeves 19 and are slidably connected to the guide sleeves 19. After the motor 121 is turned on, the output shaft of the motor 121 will drive the lower movable plate 122 to rotate, so that the connecting shaft 124 at the bottom of the movable plate 122 moves. The connecting shaft 124 pushes the movable frame 123 to move, and the guide sleeves 19 on both sides slide on the surface of the guide rods 18 to guide the movement direction of the movable frame 123, so that the movable frame 123 moves back and forth under the mounting platform 11, so that the swing plate 14 drives the placement box 6 to swing back and forth, so as to perform water washing operation on the graphite carbon nanotubes.

[0025] Limiting grooves 20 are provided on both the left and right sides of the inner wall of the washing pool 1. One side of the swing plate 14 extends into the interior of the limiting groove 20 and slides in connection with the inner wall of the limiting groove 20. When the moving frame 123 drives the connecting strip 13 below to move back and forth, one side of the swing plate 14 slides inside the limiting groove 20. The setting of the limiting groove 20 can improve the stability of the swing plate 14 when swinging back and forth.

[0026] The width between the positioning blocks 15 at the bottom of the placement box 6 is the same as the width of the swing plate 14, and the swing plate 14 and the positioning blocks 15 are slidably connected. When the placement box 6 moves down, the swing plate 14 will move between the positioning blocks 15, so that when the swing plate 14 swings back and forth, the placement box 6 will also move back and forth, shaking the graphite carbon nanotubes inside the placement box 6.

[0027] Connecting ropes 16 are fixed on both the left and right sides of the top of the shielding barrier 7, and the top of the connecting ropes 16 is fixedly connected to the bottom of the connecting plate 5. After the output shaft of the cylinder 3 pushes the lifting frame 4 down, the connecting plate 5 will drive the connecting ropes 16 down, thereby causing the placement box 6 to move down. When the placement box 6 is placed above the swing plate 14, the connecting ropes 16 will also shake when the swing plate 14 swings back and forth. The setting of the connecting ropes 16 is used to control the rise or fall of the placement box 6.

[0028] Working principle: When workers need to wash graphite carbon nanotubes, they first place the graphite carbon nanotubes to be washed inside the placement box 6. The shielding rail 7 will shield the graphite carbon nanotubes to prevent them from falling. Then, the workers open the cylinders 3 on both sides, causing the output shaft of the cylinders 3 to push the lifting frame 4 down. The connecting plate 5, through the connecting rope 16, drives the placement box 6 down, immersing it in the cleaning solution inside the washing pool 1. The placement box 6 then moves above the swing plate 14, which moves to a fixed position. Between the blocks 15, the staff simultaneously turns on the aeration pumps 8 on both sides, and the aeration disc 10 discharges nano-sized bubbles that come into contact with the graphite carbon nanotubes above. At the same time, the staff turns on the motors 121 on both sides, which causes the connecting strip 13 to drive the swing plate 14 to swing back and forth, causing the graphite carbon nanotubes inside the placement box 6 to shake so that the graphite carbon nanotubes can fully contact the bubbles below. After a period of water washing, the staff can remove the placement box 6 from the water washing tank 1, and then the staff can remove the graphite carbon nanotubes.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
