Description

Technical Field

[0001] This invention relates to the field of nanomaterial modification technology, and in particular to a surface modification device for carbon nanotubes and its usage method. Background Technology

[0002] A carbon nanotube surface modification device is a device used to change the surface properties of carbon nanotubes in order to improve their performance and application range.

[0003] A device for modifying carbon fiber surface by rapidly attaching bilayer carbon nanotubes is disclosed in Chinese Invention Patent Application Publication No. CN106906642A. Although the above device has a good modification effect on carbon fiber, is simple and easy to control, and has high safety, it ignores the fact that foam may overflow from the device during the reaction due to various reasons. After the foam overflows, it turns into liquid and flows to other places, which may damage the precision electronic instruments around the device. In addition, the above device does not have a module component to deal with the residue after the foam overflows during the reaction. This means that the foam residue needs to be cleaned manually or not cleaned temporarily. Manual cleaning is easy to be corroded by strong alkaline liquid, causing harm to the human body. If it is not cleaned temporarily, the alkaline liquid will continue to corrode the reaction vessel, shortening the life of the reaction vessel. Therefore, this application provides a carbon nanotube surface modification device and its usage method to meet the needs. Summary of the Invention

[0009] Preferably, the second sleeve has a second threaded hole on its front side, and a second bolt is threaded into the second threaded hole. A straight rod is threaded into the second sleeve through the second bolt. The straight rod and the second sleeve are mutually adapted to each other. A third threaded hole is opened at the top of the straight rod, and a third bolt is threaded into the third threaded hole.

[0010] Preferably, the straight rod is threadedly connected to a straight rod sleeve via a third bolt, a wiping cloth is provided on one side of the straight rod sleeve, a water tank is provided on the top of the top disc, the water tank is threadedly connected to the top disc via a water tank bolt, a water inlet is fixedly connected to the top of the water tank, and a water inlet threaded cap is threadedly connected to the surface of the water inlet.

[0011] Preferably, the surface of the water tank has a water pump hole, the inside of the water pump hole is equipped with a water pump, the water pump is threadedly connected to the water tank by a water pump bolt, one end of the water pump is equipped with a water pipe, the water pipe is threadedly connected to the water pump by a water pipe connecting bolt, the surface of the water pipe is fixedly connected with a water outlet pipe, and the surface of the water outlet pipe is threadedly connected with a nozzle.

[0012] Preferably, the foam overflow collection module includes a hollow frame, a reaction vessel is fixedly connected to the inner wall of the hollow frame, hollow grooves are formed on the surface of the hollow frame, a rotating rod hole is formed on the inner wall of the hollow groove, a rotating rod is provided inside the rotating rod hole, and a holding chamber is fixedly connected to one end of the rotating rod.

[0013] Preferably, a front panel is fixedly connected to the front of the holding compartment, a liquid holding box is fixedly connected to the front of the front panel, a liquid holding groove is opened on the top of the liquid holding box, a water outlet is fixedly connected to one side of the liquid holding box, a water outlet threaded cap is threadedly connected to the surface of the water outlet, a frame side bottom plate is fixedly connected to the surface of the hollow frame, and a vertical plate is fixedly connected to the top of the frame side bottom plate.

[0014] A method of using a surface modification device for carbon nanotubes includes the following steps: Step 1: When using the reactor, carbon nanotubes need to be placed inside. After the carbon nanotubes react with the mixed solution of sodium hydroxide and hydrogen peroxide, a large amount of foam may be generated due to various factors. The foam will overflow through the vent valve and may flow along the surface of the reactor. The flowing foam will flow into the foam overflow collection module, which can prevent the foam from flowing everywhere and damaging the delicate electronic instruments. After the foam stops overflowing, the workers can clean the residual foam on the reactor through the overflow cleaning module. This eliminates the need for manual cleaning, thereby reducing the corrosive impact of the foam on workers and extending the service life of the reactor. Step 2: After the foam overflows, residual foam will remain on the reactor. The residual foam needs to be cleaned up in time. At this time, the worker can remotely start the servo motor. After the servo motor starts, the rotor inside the servo motor rotates, which in turn drives the forward rod to rotate. This causes the forward rod on the gear steering mechanism and the meshing bevel gears on the top rod to rotate, which in turn causes the top rod to rotate as well. This causes the disc base, connecting cylinder and top disc to rotate together, which causes the L-shaped plate to rotate as well. The L-shaped plate will wipe the surface of the reactor with a wiping cloth. Before wiping, the first and second bolts can be loosened. By adjusting the length of the second sleeve and the straight rod, the wiping cloth can better fit the shape of the reactor surface. When the top disc rotates, the water tank will rotate with the water pump. The water pump will draw the neutralizing liquid in the water tank into the water pipe. The water in the water pipe enters the water outlet pipe and is sprayed onto the surface of the reactor through the nozzle. It should be noted that the neutralizing liquid needs to be sprayed first to neutralize the corrosiveness of the residual foam, and then the surface of the reactor should be wiped clean with a wiping cloth. Step 3: As the overflowing foam flows along the reactor, it flows onto the hollow frame and then into the liquid tank of the liquid container. Once the liquid tank is full, the weight of the liquid container increases, causing it to rotate along the rotating rod, which in turn causes the front panel to flip downwards. After the liquid container flips, the neutralizing powder stored inside is sprinkled into the foam in the vertical plate, thus neutralizing the corrosiveness of the foam.

[0015] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting an overflow cleaning module, the device can neutralize and clean the liquid residue that overflows from the reaction vessel after the foam overflows, without the need for manual cleaning. This can reduce the probability of being injured by the strong corrosiveness of the residue due to manual cleaning. At the same time, the cleaning can be directly controlled remotely by the module, which can also reduce the possibility of shortening the life of the reaction vessel due to the failure to clean the corrosive residue in time.

[0016] By incorporating a foam overflow collection module, the device can collect and hold the liquid generated by the reaction of carbon nanotubes in a mixed solution of sodium hydroxide and hydrogen peroxide. This reduces the possibility that the corrosive liquid from the overflowing bubbles could flow into other places and damage some precision electronic equipment.

[0017] In summary, the present invention has the advantages of reducing the possibility of injury to personnel during the cleaning of foam overflow after the reaction, reducing the possibility of reducing the life of the reaction vessel if it is not cleaned, and reducing the possibility of damage to precision electronic instruments caused by foam overflow after the reaction.

[0026] like Figures 1 to 3 As shown, an embodiment of the present invention provides a surface modification device for carbon nanotubes and its usage method, including a reaction vessel 1, a reaction vessel cover 2 on the top of the reaction vessel 1, the reaction vessel cover 2 being threadedly connected to the reaction vessel 1 by reaction vessel cover bolts, an overflow cleaning module 3 and an exhaust valve 4 arranged sequentially from left to right on the top of the reaction vessel cover 2, and a foam overflow collection module 5 and a reaction vessel support frame 6 arranged sequentially from top to bottom on the surface of the reaction vessel 1.

[0027] The reactor cover 2 is installed on the top of the reactor 1 by reactor cover bolts. The overflow cleaning module 3 is welded to the top of the reactor cover 2. The vent valve 4 is installed on the top of the reactor cover 2 by bolts. The foam overflow collection module 5 is welded to the surface of the reactor 1. The reactor support frame 6 is also welded to the surface of the reactor 1 and to the bottom of the foam overflow collection module 5.

[0028] During use, carbon nanotubes need to be placed in reactor 1. After the carbon nanotubes react with the mixed solution of sodium hydroxide and hydrogen peroxide, a large amount of foam may be generated due to various factors. The foam will overflow through the vent valve 4. The overflowing foam will flow along the surface of reactor 1 and into the foam overflow collection module 5. This can prevent the foam from flowing everywhere and damaging the delicate electronic instruments. After the foam overflow stops, the workers can clean the residual foam on reactor 1 through the overflow cleaning module 3. Manual cleaning is not required, which reduces the corrosive impact of foam on workers and extends the service life of reactor 1.

The top of the straight rod 315 has a third threaded hole, and a third bolt 316 is threadedly connected inside the third threaded hole.

[0033] The straight rod 315 is threadedly connected to the straight rod sleeve 317 via the third bolt 316. A wiping cloth 318 is provided on one side of the straight rod sleeve 317. A water tank 319 is provided on the top of the top disc 309. The top disc 309 is threadedly connected to the water tank 319 via the water tank bolt. A water inlet end 320 is fixedly connected to the top of the water tank 319. A water inlet end threaded cap 321 is threadedly connected to the surface of the water inlet end 320.

[0034] A water pump hole is provided on the surface of the water tank 319. A water pump 322 is provided inside the water pump hole. The water pump 322 is connected to the water tank 319 by a water pump bolt. A water pipe 323 is provided at one end of the water pump 322. The water pump 322 is connected to the water pipe 323 by a water pipe connecting bolt. A water outlet pipe 324 is fixedly connected to the surface of the water pipe 323. A nozzle 325 is threadedly connected to the surface of the water outlet pipe 324.

[0035] U-shaped plate 301 is welded to the top of reactor cover 2. Gear steering gear 302 is installed to the top of U-shaped plate 301 by steering gear bolts. Forward rod 303, top rod 305 and gear steering gear 302 are connected as a whole. Servo motor 304 is installed to the front of gear steering gear 302 by servo motor bolts and installed at the end of forward rod 303. Connecting disc 306 is welded to the top of top rod 305. Connecting disc 306 is installed to the bottom of disc base 307 by connecting disc bolts. Disc base 307, connecting cylinder 308 and top disc 309 are welded together. L-shaped plate 310 is welded to the surface of top disc 309. First sleeve 311 is welded to L-shaped plate 310. The second sleeve 313 is fitted into the first sleeve 311, and the second sleeve 313 and the first sleeve 311 are fixed together by the first bolt 312. The straight rod 315 is fitted into the second sleeve 313, and the straight rod 315 and the second sleeve 313 are fixed together by the second bolt 314. The straight rod sleeve 317 is fitted onto the straight rod 315, and the straight rod sleeve 317 and the straight rod 315 are fixed together by the third bolt 316. The wiping cloth 318 is adhered to the straight rod sleeve 317. The water tank 319 is installed on the top of the top disc 309 by water tank bolts. The water inlet end 320 is welded to the top of the water tank 319. The threaded cap 321 of the water inlet end is screwed onto the surface of the water inlet end 320. The water pump 322 is placed into the water pump hole of the water tank 319 and installed on the water tank 319 by water pump bolts. The water pipe 323 is installed on the water pump 322 by water pipe connecting bolts. The water outlet pipe 324 is integrally formed with the water pipe 323. The nozzle 325 is screwed onto the water outlet pipe 324.

[0036] After the foam overflows, residual foam will remain on reactor 1. This residual foam needs to be cleaned promptly. At this time, the worker can remotely start the servo motor 304. After the servo motor 304 starts, the rotor inside the servo motor 304 rotates, which in turn drives the forward rod 303 to rotate. This causes the bevel gears meshing on the forward rod 303 on the gear steering mechanism 302 and the top rod 305 to rotate, which in turn causes the top rod 305 to rotate as well. This causes the disc base 307, connecting cylinder 308, and top disc 309 to rotate together, causing the L-shaped plate 310 to rotate as well. The L-shaped plate 310, carrying the wiping cloth 318, will wipe the surface of reactor 1. Before wiping, the first bolt 312 and the second bolt 314 can be loosened. By adjusting the length of the second sleeve 313 and the straight rod 315, the wiping cloth 318 can better adapt to the shape of the surface of the reactor 1. When the top disc 309 rotates, the water tank 319 will rotate together with the water pump 322. The water pump 322 will draw the neutralizing liquid in the water tank 319 into the water pipe 323. The water in the water pipe 323 enters the outlet pipe 324 and is sprayed onto the surface of the reactor 1 through the nozzle 325. It should be noted that the neutralizing liquid needs to be sprayed first to neutralize the corrosiveness of the residual foam, and then the surface of the reactor 1 can be wiped clean with the wiping cloth 318.

[0037] By setting the overflow cleaning module 3, the device can neutralize and clean the liquid residue that overflows from the reaction vessel 1 after the foam overflows, without the need for manual cleaning. This can reduce the probability of being injured by the strong corrosiveness of the residue due to manual cleaning. At the same time, the cleaning can be remotely controlled by the module, which can also reduce the possibility of shortening the life of the reaction vessel 1 due to the failure to clean the corrosive residue in time.

[0038] like Figures 11 to 14 As shown, in this embodiment, the foam overflow collection module 5 includes a hollow frame 501, and a reaction vessel 1 is fixedly connected to the inner wall of the hollow frame 501. Hollow grooves are opened on the surface of the hollow frame 501, and rotating rod holes are opened on the inner wall of the hollow grooves. A rotating rod 502 is provided inside the rotating rod hole, and a holding chamber 503 is fixedly connected to one end of the rotating rod 502.

[0039] A front panel 504 is fixedly connected to the front of the container 503. A liquid container 505 is fixedly connected to the front of the front panel 504. A liquid trough is opened on the top of the liquid container 505. A water outlet 506 is fixedly connected to one side of the liquid container 505. A water outlet threaded cap 507 is threadedly connected to the surface of the water outlet 506. A frame side bottom plate 508 is fixedly connected to the surface of the hollow frame 501. A vertical plate 509 is fixedly connected to the top of the frame side bottom plate 508.

[0040] The hollow frame 501 is welded to the reactor 1. The hollow trough and the hollow frame 501 are integrally formed. The rotating rod hole is opened on the side wall of the hollow trough. The rotating rod 502 is inserted into the rotating rod hole. The holding chamber 503 and the rotating rod 502 are welded together. The front panel 504 is welded to the holding chamber 503. The liquid holding box 505 is welded to the front panel 504. The liquid holding trough and the liquid holding box 505 are integrally formed. The water outlet 506 is welded to the side of the liquid holding box 505. The threaded cap 507 of the water outlet is screwed onto the surface of the water outlet 506. The frame side bottom plate 508 is welded to the surface of the hollow frame 501. The vertical plate 509 is welded to the top of the frame side bottom plate 508.

[0041] When the overflowing foam flows along the reactor 1, it flows along the surface of the reactor 1 onto the hollow frame 501. Then, the foam flows along the hollow frame 501 into the liquid tank of the liquid container 505. After the liquid tank is filled, the weight of the liquid container 505 increases, which causes the liquid container 505 to rotate along with the front panel 504 via the rotating rod 502. As a result, the front panel 504 and the storage chamber 503 are flipped downwards. After the storage chamber 503 is flipped, the neutralizing powder stored inside it will be sprinkled into the foam in the vertical plate 509, thereby neutralizing the corrosiveness of the foam.

[0042] By setting up a foam overflow collection module 5, when the carbon nanotubes are placed in a mixed solution of sodium hydroxide and hydrogen peroxide, a large number of corrosive bubbles are generated and overflow. The device can collect and hold the liquid formed by the overflowing bubbles. This can reduce the possibility that the corrosive liquid will flow into other places and cause damage to some precision electronic equipment after the overflowing bubbles turn into liquid.

[0043] All electrical components mentioned in this article are connected to an external main controller and 220V AC mains power, and the main controller can be a conventional known device such as a computer that can control it.

[0044] A method of using a surface modification device for carbon nanotubes includes the following steps: Step 1: When using the equipment, carbon nanotubes need to be placed in the reactor 1. After the carbon nanotubes react with the mixed solution of sodium hydroxide and hydrogen peroxide, a large amount of foam may be generated due to various factors. The foam will overflow through the vent valve 4. The overflowing foam will flow along the surface of the reactor 1 and into the foam overflow collection module 5. This can prevent the foam from flowing everywhere and damaging the delicate electronic instruments. After the foam stops overflowing, the workers can clean the residual foam on the reactor 1 through the overflow cleaning module 3. There is no need for manual cleaning, which reduces the corrosive impact of the foam on the workers and extends the service life of the reactor 1. Step 2: After the foam overflows, residual foam will remain on reactor 1. This residual foam needs to be cleaned promptly. At this time, the worker can remotely start the servo motor 304. After the servo motor 304 starts, the rotor inside it rotates, which in turn drives the forward rod 303 to rotate. This causes the bevel gears meshing on the forward rod 303 on the gear steering mechanism 302 and the top rod 305 to rotate, which in turn causes the top rod 305 to rotate as well. This causes the disc base 307, connecting cylinder 308, and top disc 309 to rotate together, causing the L-shaped plate 310 to rotate as well. The L-shaped plate 310, along with the wiping cloth 318, will wipe the surface of reactor 1. Before wiping, the first bolt 312 and the second bolt 314 can be loosened. By adjusting the length of the second sleeve 313 and the straight rod 315, the wiping cloth 318 can better adapt to the shape of the surface of the reactor 1. When the top disc 309 rotates, the water tank 319 will rotate together with the water pump 322. The water pump 322 will draw the neutralizing liquid in the water tank 319 into the water pipe 323. The water in the water pipe 323 enters the outlet pipe 324 and is sprayed onto the surface of the reactor 1 through the nozzle 325. It should be noted that the neutralizing liquid needs to be sprayed first to neutralize the corrosiveness of the residual foam, and then the surface of the reactor 1 can be wiped clean with the wiping cloth 318. Step 3: As the overflowing foam flows along the reactor 1, it flows down the surface of the reactor 1 onto the hollow frame 501. Then, the foam flows down the hollow frame 501 into the liquid tank of the liquid container 505. After the liquid tank is filled, the weight of the liquid container 505 increases, causing the liquid container 505 to rotate along with the front panel 504 via the rotating rod 502. As a result, the front panel 504 and the storage chamber 503 flip downwards. After the storage chamber 503 flips, the neutralizing powder stored inside it will be sprinkled into the foam in the vertical plate 509, thereby neutralizing the corrosiveness of the foam.

[0045] The technical solution provided by this invention is as follows: Carbon nanotubes are placed in a reaction vessel 1. After the carbon nanotubes react with the mixed solution of sodium hydroxide and hydrogen peroxide, a large amount of foam may be generated due to various factors. The foam will overflow through the vent valve 4 and may flow along the surface of the reaction vessel 1. The flowing foam will flow into the foam overflow collection module 5, which can prevent the foam from flowing everywhere and damaging delicate electronic instruments. After the foam overflow stops, the worker can clean the residual foam on the reaction vessel 1 through the overflow cleaning module 3, eliminating the need for manual cleaning and reducing the corrosive effect of foam on workers. The erosion can also extend the service life of reactor 1. After the foam overflows, the residual foam will remain on reactor 1. The residual foam needs to be cleaned in time. At this time, the worker can remotely start the servo motor 304. After the servo motor 304 is started, the rotor inside the servo motor 304 rotates, which in turn drives the forward rod 303 to rotate. This causes the bevel gears meshing on the forward rod 303 on the gear steering mechanism 302 and the top rod 305 to rotate, which in turn causes the top rod 305 to rotate as well. This causes the disc base 307, the connecting cylinder 308 and the top disc 309 to rotate together, which causes the L-shaped plate 310 to rotate as well. The wiping cloth 318 will wipe the surface of the reactor 1. Before wiping, the first bolt 312 and the second bolt 314 can be loosened. By adjusting the length of the second sleeve 313 and the straight rod 315, the wiping cloth 318 can better adapt to the shape of the reactor 1 surface. When the top disc 309 rotates, the water tank 319 will rotate along with the water pump 322. The water pump 322 will draw the neutralizing liquid in the water tank 319 into the water pipe 323. The water in the water pipe 323 will enter the outlet pipe 324 and be sprayed onto the surface of the reactor 1 through the nozzle 325. It should be noted that a neutralizing liquid needs to be sprayed first to neutralize the corrosiveness of the residual foam. Then, the surface of the reactor 1 is wiped clean with a cloth 318. When the overflowing foam flows along the surface of the reactor 1, it flows onto the hollow frame 501. Then, the foam flows along the hollow frame 501 into the liquid tank of the liquid container 505. After the liquid tank is filled, the weight of the liquid container 505 increases, which causes the liquid container 505 to rotate along with the front panel 504 via the rotating rod 502. As a result, the front panel 504 and the container 503 are flipped downwards. After the container 503 is flipped, the neutralizing powder stored inside it will be sprinkled into the foam in the vertical plate 509, thereby neutralizing the corrosiveness in the foam.

10. The method of using the carbon nanotube surface modification device according to claims 1-9, characterized in that, Includes the following steps: Step 1: When using, carbon nanotubes need to be placed in the reactor (1). After the carbon nanotubes react with the mixed solution of sodium hydroxide and hydrogen peroxide, a large amount of foam may be generated due to various factors. The foam will overflow through the vent valve (4). The overflowed foam will overflow from the vent valve (4) and may flow along the surface of the reactor (1). The flowing foam will flow into the foam overflow collection module (5). This can prevent the foam from flowing everywhere and damaging the precision electronic instruments. After the foam stops overflowing, the workers can clean the residual foam on the reactor (1) through the overflow cleaning module (3). There is no need to clean it manually, thereby reducing the corrosive impact of the foam on the workers and extending the service life of the reactor (1). Step 2: After the foam overflows, the remaining foam will remain on the reactor (1). The remaining foam needs to be cleaned up in time. At this time, the worker can remotely start the servo motor (304). After the servo motor (304) is started, the rotor inside the servo motor (304) rotates, which in turn drives the forward rod (303) to rotate, thereby causing the bevel gears meshing on the forward rod (303) on the gear steering machine (302) and the top rod (305) to rotate, which in turn causes the top rod (305) to rotate as well, thereby causing the disc base (307), the connecting cylinder (308) and the top disc (309) to rotate together, thereby causing the L-shaped plate (310) to rotate as well. The L-shaped plate (310) will wipe the surface of the reactor (1) with the wiping cloth (318). Before wiping, the first bolt (312) and the second bolt (314) can be loosened. By adjusting the length of the second sleeve (313) and the straight rod (315), the wiping cloth (318) can better fit the shape of the surface of the reactor (1). When the top disc (309) rotates, the water tank (319) will rotate with the water pump (322). The water pump (322) will draw the liquid used for neutralization in the water tank (319) into the water pipe (323). The water in the water pipe (323) enters the water outlet pipe (324) and is sprayed onto the surface of the reactor (1) through the nozzle (325). It should be noted that the neutralizing liquid needs to be sprayed first to neutralize the corrosiveness of the residual foam, and then the surface of the reactor (1) is wiped clean with the wiping cloth (318). Step 3: When the overflowing foam flows along the reactor (1), the foam will flow along the surface of the reactor (1) to the hollow frame (501). Then the foam will flow along the hollow frame (501) to the liquid tank of the liquid container (505). After the liquid tank is filled, the weight of the liquid container (505) increases, which causes the liquid container (505) to rotate along the front panel (504) via the rotating rod (502). As a result, the front panel (504) and the storage bin (503) flip downwards. After the storage bin (503) flips, the neutralizing powder stored inside it will be sprinkled into the foam in the vertical plate (509), thereby neutralizing the corrosiveness in the foam.
