Description

Technical Field

[0001] The present application relates to the technical field of powder transportation, and in particular to a single-walled carbon nanotube powder transportation device. Background Art

[0002] Single-walled carbon nanotubes are tubular structures formed by curling up a single layer of graphene sheets. Their diameter is usually between a few nanometers and tens of nanometers, and their length can reach several microns or even longer. Single-walled carbon nanotube powder is a large amount of single-walled carbon nanotubes in powder form, which is easy to store, transport and use.

[0003] In the production process of single-walled carbon nanotube powder, in order to prevent the single-walled carbon nanotube powder from being contaminated by the outside world, it needs to be transported in a sealed manner to maintain its purity and performance; For example, the patent with publication number CN221116025U specifically discloses a device for conveying carbon nanotube powder, which conveys nitrogen from a first nitrogen source into a first conveying pipe through an air pipe, and conveys the carbon nanotube powder in the first conveying pipe to a second conveying pipe through the nitrogen, and at the same time, the servo motor is started, and the lever is driven by the shaft to shift the carbon nanotube powder in the first conveying pipe, and the spiral blade at the bottom end of the shaft rotates synchronously to guide the connection between the first conveying pipe and the second conveying pipe, ensuring that the carbon nanotube powder in the first conveying pipe can be smoothly conveyed to the second conveying pipe, and the second nitrogen source conveys nitrogen to the second conveying pipe, and at the same time, the fan is started, and the nitrogen conveying direction and the fan air supply direction are both toward the powder bin, so that the carbon nanotube powder conveyed from the first conveying pipe to the second conveying pipe can be quickly conveyed to the powder bin; However, during the implementation of the above patent, although blockage can be avoided, only the connection between the first conveying pipe and the second conveying pipe can be prevented from being blocked. Since the carbon nanotube powder may generate static electricity due to friction, collision and other reasons during transportation, the static electricity will cause the carbon nanotube particles to be adsorbed on the inner wall of the pipe; As carbon nanotube powders continue to accumulate on the inner wall of the pipeline, they may gradually clog the pipeline, resulting in a reduction in transportation flow or even a complete interruption. Therefore, the inner wall of the pipeline needs to be cleaned regularly to prevent excessive powders from attaching to the inner wall of the pipeline and affecting subsequent powder transportation. Therefore, it is necessary to provide a single-walled carbon nanotube powder conveying device to solve the above problems.

[0019] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0021] Example 1: This example specifically describes the structure and working process of transporting single-walled carbon nanotube powder, specifically: like Figure 1 As shown, the present application provides a single-walled carbon nanotube powder conveying device, including a nitrogen pump 1, and a temporary storage component 2 is arranged on one side of the nitrogen pump 1, and the temporary storage component 2 is used to buffer the flow difference of the single-walled carbon nanotube powder (hereinafter referred to as material) between the previous and next processes to ensure the continuity and stability of the conveying process; like Figure 1 As shown, the temporary storage component 2 includes a temporary storage tank 21 arranged on one side of the nitrogen pump 1, and the temporary storage tank 21 is respectively provided with a feed port 22 and a discharge portion 24, and a feed pipe 23 is provided on the feed port 22, and the end of the feed pipe 23 away from the feed port 22 is connected to the equipment of the previous process in the production process (such as grinding equipment); like Fig.10 As shown, the discharge part 24 is used to control the discharge speed and distribution amount of the material in the temporary storage tank 21 when discharging the material. The discharge part 24 includes a distribution pipe 242 arranged at the discharge position of the temporary storage tank 21. The distribution pipe 242 has a discharge port 247 connected to the discharge position of the temporary storage tank 21, and also has a drop port 248 for discharging the material. Meanwhile, a stepper motor 243 is fixedly mounted on the material distribution pipe 242, and a material distribution shaft 244 is fixedly mounted on the output end of the stepper motor 243. The material distribution shaft 244 is rotatably mounted inside the material distribution pipe 242, and a plurality of material distribution plates 245 are fixedly mounted on the circumferential surface of the material distribution shaft 244. The material distribution plates 245 are located between the material discharge port 247 and the material discharge port 248 of the material distribution pipe 242. It should be noted that a material supply area 246 for temporarily storing materials is formed between the plurality of material distribution plates 245. When unloading, the material in the temporary storage tank 21 enters the distribution pipe 242 from the unloading port 247. Driven by the stepper motor 243, the distribution shaft 244 drives the distribution plate 245 to rotate. At this time, the falling material will continue to fall into the feeding area 246 near the unloading port 247, and due to the continuous rotation of the stepper motor 243, the feeding area 246 near the unloading port 247 is driven to rotate in the distribution pipe 242. The material will not fly out due to the obstruction of the tube wall of the distribution pipe 242, and then rotate with the feeding area 246. When the feeding area 246 with the material rotates to the drop port 248, the tube wall of the distribution pipe 242 will not block the material. At this time, under the action of gravity, the material falls to the drop port 248. At the same time, a discharge pipe 241 is provided at the material outlet 248 of the material distribution pipe 242, and a first delivery pipe 25 is connected to the output end of the nitrogen pump 1, and the first delivery pipe 25 is connected to the discharge pipe 241; Thus, the material enters the temporary storage tank 21 from the feed port 22 of the temporary storage tank 21 through the feed pipe 23, and passes through the discharge portion 24 of the temporary storage tank 21 to control the falling speed and distribution amount of the material, and then the material enters the first conveying pipe 25 through the discharge pipe 241. At this time, the nitrogen pump 1 is started to apply nitrogen to the first conveying pipe 25 to push the material in the first conveying pipe 25 to move; At the same time, a storage component 3 is provided on one side of the temporary storage component 2, and the storage component 3 is used to store the materials transported by the temporary storage component 2; like Figure 1 and Figure 3 As shown, the storage assembly 3 includes a mounting frame 31 disposed on one side of the temporary storage tank 21, on which a storage tank 32 is fixedly mounted, and a feed trough (not shown in the figure) is disposed on the storage tank 32, so that the material can be input into the storage tank 32 through the feed trough; At the same time, a filter tank 33 is fixedly mounted on the mounting frame 31, and the discharge position of the filter tank 33 is connected to the feed trough to facilitate filtering of the material; A feed pipe 34 is provided on the filter tank 33, and a second delivery pipe 36 is provided at one end of the first delivery pipe 25 away from the discharge portion 24. A three-way valve 35 is connected between the second delivery pipe 36 and the feed pipe 34, so as to form two sets of flow channels through the three-way valve 35. At the same time, an air outlet 37 is provided on the filter tank 33 so that nitrogen can be output through the air outlet 37, and a filter screen (not shown in the figure) is provided at the air outlet 37 so as to separate nitrogen and materials; The material in the first conveying pipe 25 enters the filter tank 33 through the second conveying pipe 36 and the three-way valve 35, and enters the storage tank 32 from the discharge position of the filter tank 33 for storage, while the nitrogen is discharged through the gas outlet 37, and the filter screen can effectively prevent part of the material driven by the nitrogen from being output to the outside, so that the nitrogen and the material are separated; To sum up, when transporting materials, the processed materials enter the temporary storage component 2 through the feed pipe 23 to buffer the flow difference of the materials between the previous and next processes, and then the materials are controlled to fall into the first conveying pipe 25 through the temporary storage component 2, and the nitrogen pump 1 is started to input nitrogen into the first conveying pipe 25, and the materials in the first conveying pipe 25 are input into the second conveying pipe 36 through the nitrogen, and then the materials enter the filter tank 33 through the three-way valve 35 and the feed pipe 34, and enter the storage tank 32 through the discharge trough of the filter tank 33.

[0022] Embodiment 2: During the transportation of the above materials, static electricity may be generated due to friction, collision, etc. The static electricity will cause the materials to be adsorbed on the inner wall of the pipe. As the materials continue to accumulate on the inner wall of the pipe, the pipe may be gradually blocked, resulting in a reduction in the transportation flow or even a complete interruption, thereby affecting the transportation of subsequent materials; In order to solve this problem, a pipeline cleaning assembly 4 is provided on the first delivery pipe 25, and the pipeline cleaning assembly 4 is used to clean the inner walls of the first delivery pipe 25 and the second delivery pipe 36; like Figure 1-Figure 2 As shown, the pipeline cleaning assembly 4 includes a ball tube 42 obliquely arranged on the first delivery pipe 25, and the direction of the ball tube 42 is inclined along the direction close to the first delivery pipe 25, and the height gradually decreases; At the same time, a first transport pipe 43 is provided at one end of the goal pipe 42 away from the first transport pipe 25, and a cleaning ball adapted to the goal pipe 42 is provided on the first transport pipe 43; It should be noted that the cleaning ball is made of elastic material, so that when the cleaning ball passes through the goal tube 42 and enters the first conveying tube 25, the cleaning ball abuts against the inner wall of the first conveying tube 25, so that when the cleaning ball is subsequently pushed to move in the pipeline, the materials attached to the inner wall of the pipeline are pushed and cleaned, and the first conveying tube 43 is synchronously inclined along the inclination direction of the goal tube 42, and the diameter of the first conveying tube 43 is larger than the diameter of the goal tube 42, so that the cleaning ball can roll toward the goal tube 42 along the pipeline direction of the first conveying tube 43 under the action of gravity; Continue to refer Figure 1, and a return pipe 41 is provided at another installation port of the three-way valve 35. It should be noted that the three-way valve 35 is provided with an actuator, and the actuator is controlled by the PLC system, so as to control the three-way valve 35 to perform the channel switching action through the PLC system to complete the connection between the return pipe 41 and the second delivery pipe 36, and the return pipe 41, the second delivery pipe 36 and the first delivery pipe 25 have the same diameters, and at the same time, a second delivery pipe 44 (such as Figure 8 ), and the second transport pipe 44 is synchronously inclined along the inclination direction of the first transport pipe 43, and at the same time, one end of the return pipe 41 close to the second transport pipe 44 is opened, so that the nitrogen pushes the cleaning ball out from the opening of the return pipe 41, and the nitrogen can be discharged into the air through the opening of the return pipe 41. Since nitrogen itself is non-toxic, it will not have a toxic effect on human cells or tissues, nor will it interfere with the normal physiological functions of the human body. At the same time, the human body has a certain metabolic capacity for nitrogen, and the inhaled nitrogen is mainly discharged from the body through the breathing process, and will not accumulate in the body to cause harm; When the cleaning ball enters the first delivery pipe 25 through the ball pipe 42, the nitrogen pump 1 drives the cleaning ball to enter the second delivery pipe 36, and enters the return pipe 41 through the three-way valve 35, thereby cleaning the materials attached to the inner walls of the first delivery pipe 25 and the second delivery pipe 36 and pushing them out to the second delivery pipe 44; In order to smoothly press the cleaning ball into the goal tube 42, a ball pressing assembly 5 is provided on the goal tube 42, and the ball pressing assembly 5 is used to press the cleaning ball into the goal tube 42 and the first delivery tube 25; like Figure 1-Figure 2 and Figure 5-Figure 6 As shown, the ball pressing assembly 5 includes a mounting plate 52 mounted on the goal tube 42, the mounting plate 52 is arranged parallel to the axial direction of the goal tube 42, and a cylinder 51 is fixedly mounted on one side of the mounting plate 52, and a fixing plate 58 is fixedly mounted on the output end of the cylinder 51, so that the fixing plate 58 can be driven to move synchronously along the axial direction parallel to the goal tube 42 through the telescopic movement of the cylinder 51; Meanwhile, a slide rail (not shown in the figure) perpendicular to the axis of the goal tube 42 is provided on the fixed plate 58, and a connecting block 59 is slidably provided on the slide rail, so that the connecting block 59 can move along the slide rail. In order to prevent the connecting block 59 from falling off the slide rail, limit blocks (not shown in the figure) are provided at both upper and lower ends of the slide rail. like Figure 5As shown, a horizontally arranged connecting rod 56 is fixedly mounted on the connecting block 59, and a roller 57 is rotatably mounted on the connecting rod 56. At the same time, a slideway 55 adapted to the roller 57 is arranged on the mounting plate 52, so that the roller 57 can roll inside the slideway 55. It should be noted that the connecting rod 56 passes through the slideway 55 and penetrates to the other side of the mounting plate 52; Meanwhile, the slideway 55 has a first slide groove 551 located at the lower end of the mounting plate 52, and a second slide groove 552 located at the upper end of the mounting plate 52. The first slide groove 551 and the second slide groove 552 are both arranged parallel to the axis of the goal tube 42, and an inclined slide groove 553 suitable for the roller 57 to slide upward or downward is connected between the first slide groove 551 and the second slide groove 552. A push rod 54 is fixedly installed at a position where the connecting rod 56 protrudes from the mounting plate 52. The push rod 54 is arranged parallel to the axis of the goal tube 42, and a piston plate 53 adapted to the feed tube 34 is fixedly arranged at one end of the push rod 54 away from the connecting rod 56; It should be noted that, because the axis of the first slide groove 551 and the axis of the goal tube 42 are on the same horizontal plane, when the roller 57 moves in the first slide groove 551, the piston plate 53 is suitable for moving along the axis direction of the goal tube 42; In summary, in the initial state, the roller 57 and the connecting rod 56 are located at one end of the first slide groove 551 close to the goal tube 42, at this time, the connecting block 59 is located at the bottom of the fixed block, and the piston plate 53 and the push rod 54 are located in the goal tube 42 to seal the goal tube 42 to prevent gas diversion when transporting materials through nitrogen, and at this time, the cleaning ball rolls toward the goal tube 42 through the inclined design of the first transport tube 43 under the action of gravity, until the cleaning ball continues to abut against one side of the connecting rod 56 under the action of gravity; During cleaning, the PLC controls the second conveying pipe 36 to be connected with the return pipe 41. At this time, the cleaning ball needs to be pressed into the first conveying pipe 25, and the cylinder 51 is started. The cylinder 51 extends, driving the fixing plate 58 to move horizontally, and then driving the connecting block 59 to move, thereby driving the roller 57 to move from the first slide groove 551 to the inclined slide groove 553 through the connecting rod 56, and then driving the piston plate 53 to move through the push rod 54. At the same time, the connecting rod 56 pushes the cleaning ball to move upward along the inclined direction of the first conveying pipe 43; When the roller 57 moves to the inclined groove 553, the piston plate 53 is separated from the goal tube 42, and then the cylinder 51 continues to push. Under the thrust of the cylinder 51, the roller 57 gradually moves upward along the inclined surface of the inclined groove 553, and then drives the connecting block 59 to gradually move upward along the vertical direction of the fixed plate 58 through the connecting rod 56, thereby driving the push rod 54 and the piston plate 53 to gradually move upward; When the roller 57 moves to the second slide groove 552, the connecting block 59 moves to the top of the fixing plate 58, thereby driving the roller 57 to move above the goal tube 42, and the piston plate 53 moves to the top of the goal tube 42 simultaneously. At this time, the connecting rod 56 loses the limit on the cleaning ball, and the cleaning ball moves toward the goal tube 42 along the inclined direction of the first conveying pipe 25 under the action of gravity until it abuts against one end of the goal tube 42. Then the cylinder 51 is reset, driving the fixing plate 58 to reset, thereby driving the connecting rod 56 to reset through the connecting block 59, and then driving the roller 57 to move from the second slide to the inclined slide groove 553, synchronously driving the piston plate 53 and the push rod 54 to move. When the roller 57 moves to the first slide groove 551 through the inclined slide groove 553, the axis of the piston plate 53 and the axis of the goal tube 42 are on the same axis, and the piston plate 53 and the cleaning ball are against each other. Then the cylinder 51 continues to reset, thereby driving the roller 57 to move along the first slide groove 551 toward the goal tube 42, thereby synchronously driving the piston plate 53 and the push rod 54 to press the cleaning ball into the goal tube 42, until the roller 57 moves to the end of the first slide groove 551 close to the goal tube 42, at which time the piston plate 53 presses the cleaning liquid from the goal tube 42 into the first delivery pipe 25, and the piston plate 53 seals the goal tube 42. At the same time, a ball cleaning assembly 6 is provided on one side of the ball pressing assembly 5, and the ball cleaning assembly 6 is used for cleaning the cleaning ball; like Figure 1 and Figure 4 As shown, the ball cleaning assembly 6 includes a base 61 disposed between the first transport tube 43 and the second transport tube 44, and two groups of baffles 62 arranged opposite to each other are fixedly mounted on the base 61, and a top plate 63 is fixedly mounted on the top of the two groups of baffles 62, and cleaning rollers 65 are bearing-mounted on both groups of baffles 62, and the two groups of cleaning rollers 65 are arranged opposite to each other, and spiral blades 69 are arranged on both groups of cleaning rollers 65; It should be noted that the spiral blade 69 is arranged on the cleaning roller 65 with a certain pitch and spiral angle to form a continuous spiral channel, and the spiral angle of the spiral blade 69 is small or close to a straight line shape to reduce the resistance of the material during the conveying process; like Figure 7-Figure 9 As shown, a plurality of second circles 612 suitable for the movement of the cleaning balls are formed between the two sets of spiral channels, and a brush is provided on the spiral blade 69 to clean the surface of the cleaning balls. A servo motor 66 is fixedly mounted on the two sets of baffles 62, and the output ends of the two sets of servo motors 66 are respectively connected to one end of the two sets of cleaning rollers 65; It should be noted that the end of the spiral blade 69 close to the second transport pipe 44 is the starting end, and the end away from the second transport pipe 44 is the terminal end, so that when the cleaning roller 65 rotates, the two groups of starting ends form a first circle 610 suitable for the cleaning balls to enter, and the two groups of terminal ends form a third circle 613 suitable for the cleaning balls to separate; Driven by the servo motor 66, the two groups of cleaning rollers 65 rotate synchronously in the same direction, thereby driving the two groups of spiral blades 69 to rotate. At this time, the cleaning ball pushed by the nitrogen to the second conveying pipe 36 moves toward the starting end of the spiral blade 69 between the two groups of cleaning rollers 65 under the push of the nitrogen. As the spiral blade 69 rotates, the starting ends of the two groups of spiral blades 69 gradually approach the ball and contact it. The ball is acted on by the thrust of the spiral blade 69 and starts to move forward until it enters the first circle 610. As the spiral blade 69 continues to rotate, the ball is pushed by the spiral blade 69 and gradually enters the second circle 612 from the first circle 610. The second circle 612 is the space formed between the two sets of spiral channels. The ball continues to be pushed by the spiral blade 69 and continues to move forward. When the ball reaches the terminal end of the spiral blade 69, the ball is pushed by the terminal end and enters the two groups of terminal ends to form a third circle 613 suitable for cleaning ball separation, and is guided and separated. In the process of the cleaning ball moving, the brush on the spiral blade 69 cleans the surface of the cleaning ball. It should be noted that a guide bar (not shown in the figure) is provided between the first transport tube 43 and the second transport tube 44, and the guide bar is located below the first circle 610 to prevent the cleaning ball from falling out during movement; Continue to refer Figure 4 , and a water pump 67 is provided on one side of the base 61, and a shunt pipe 68 is provided at the output end of the water pump 67, and the two ends of the shunt pipe 68 away from the output end of the water pump 67 are respectively sealed and installed in the two groups of cleaning rollers 65 with bearings, and a plurality of spray holes (not shown in the figure) are provided on the two groups of cleaning rollers 65.
