[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example: Figures 1-6 As shown, the present invention provides a technical solution for a stirring device for carbon nanotube slurry with a uniform dispersion function, characterized in that: The stirring device for carbon nanotube slurry with uniform dispersion function includes a base 1, on which a mounting frame 2 and a water tank 3 are installed, a pump 10 is installed in the water tank 3, a mixing drum 4 is installed on the mounting frame 2, an upper cover 5 is installed on the mixing drum 4, a water inlet 6 and a feed port 7 are provided on the upper cover 5, the water inlet 6 is connected to the pump 10 through a water pipe 11, a water storage layer 8 is provided in the upper cover 5, and a plurality of water outlets 9 are provided at the lower end of the upper cover 5, and the plurality of water outlets 9 are evenly distributed at the lower end of the upper cover 5.

[0022] Before stirring, carbon nanotubes are added into the mixing drum 4 through the feed port 7, and at the same time, the pump 10 is started to extract the stirring water in the water tank 3. The stirring water enters the water storage layer 8 through the water pipe 11 and flows into the mixing drum 4 from the water outlet 9. Since the water outlet 9 is evenly distributed on the upper cover 5, the stirring water can flow evenly into the mixing drum 4, avoiding the phenomenon of local over-thinness and local over-thickness caused by single-point addition of stirring water, which can speed up subsequent stirring operations and improve mixing uniformity.

[0023] like Figure 1-Figure 7 As shown, a driving motor 12 is installed on the mounting frame 2, a motor gear 13 is installed on the output shaft of the driving motor 12, a main gear 14 is rotatably installed on the mounting frame 2, the main gear 14 is engaged with the motor gear 13, a first threaded sleeve 15 is coaxially mounted on the main gear 14, a stirring screw 16 is mounted on the inner thread of the first threaded sleeve 15, a fixing plate 21 is mounted on the upper end of the stirring screw 16, a rod mounting hole 19 is provided on the first threaded sleeve 15, an electric telescopic rod 20 is mounted in the rod mounting hole 19, a fixing hole 22 is provided on the fixing plate 21, a stirring rod 17 is mounted on the lower end of the stirring screw 16, and two stirring blades 18 are mounted on the stirring rod 17.

[0024] When the pump 10 inputs stirring water into the mixing drum 4, the drive motor 12 is started synchronously at a low speed, and the drive motor 12 drives the motor gear 13 to rotate. Due to the gear meshing, the motor gear 13 drives the first threaded sleeve 15 to rotate through the main gear 14. The first threaded sleeve 15 causes the stirring screw 16 to reciprocate up and down along the first threaded sleeve 15 through the thread matching. When the stirring screw 16 reciprocates, it drives the stirring blade 18 to move synchronously through the stirring rod 17. The reciprocating movement of the stirring blade 18 will pre-mix the carbon nanotubes and the stirring water in the mixing drum 4 at a low speed in the vertical direction, thereby improving the mixing uniformity; After the feeding is completed, the pump 10 and the drive motor 12 both stop working. At this time, the fixed plate 21 is in contact with the first threaded sleeve 15. The drive motor 12 is started again and the electric telescopic rod 20 is controlled to extend. The end of the electric telescopic rod 20 extends into the fixing hole 22. When the drive motor 12 drives the first threaded sleeve 15 to rotate, the stirring screw 16 rotates synchronously with the first threaded sleeve 15 due to the positioning of the electric telescopic rod 20. At this time, the first threaded sleeve 15 and the stirring screw 16 are equivalent to a rigid connection. The first threaded sleeve 15 drives the stirring blade 18 to rotate at a high speed through the stirring screw 16, stirring the mixture at a high speed. The mixing uniformity is further improved by combining multi-stage mixing of low-speed premixing and high-speed stirring.

[0025] A cooling assembly 23 is provided on the base 1 , and the cooling assembly 23 provides driving force by the rotation of the main gear 14 . A detection assembly 24 is provided in the stirring screw 16 .

[0026] like Figures 1-8 As shown, the cooling assembly 23 includes a spiral cooling tube 2301, a cooling box 2302, a partition 2311, a cooling plate 2312, a liquid infusion tube 2313, a liquid inlet tube 2327, a liquid outlet tube 2328 and a guide hole 2329; A spiral cooling tube 2301 is installed on the outside of the mixing drum 4, and a cooling box 2302 is installed on the base 1. Two cooling plates 2312 and a partition 2311 are installed in the cooling box 2302. The partition 2311 is located below the two cooling plates 2312. The cross-section of the cooling plate 2312 is trapezoidal. A guide hole 2329 is opened on one side of the thin edge of the cooling plate 2312. The guide holes 2329 of the two cooling plates 2312 are located on opposite sides. An infusion tube 2313 is installed below the partition 2311. The infusion tube 2313 is connected to the lower end of the spiral cooling tube 2301 through the liquid inlet tube 2327, and the cooling box 2302 is connected to the upper end of the spiral cooling tube 2301 through the liquid outlet tube 2328.

[0027] When the mixture is stirred, the coolant flows from the cooling box 2302 through the liquid infusion pipe 2313 and the liquid inlet pipe 2327 into the spiral cooling tube 2301, and finally flows back to the top of the cooling box 2302 from the liquid outlet pipe 2328. After the coolant enters the cooling box 2302 again, the inclined surface of the cooling plate 2312 will flow to the guide hole 2329. After the used coolant is re-cooled by the two cooling plates 2312, the coolant flows back from the partition 2311 into the liquid infusion pipe 2313 for reuse, thereby cooling the mixing drum 4, preventing changes in the properties of the slurry, thereby ensuring product quality, and at the same time realizing the reuse of the coolant and reducing production costs.

[0028] The cooling assembly 23 further includes a gear mounting plate 2303, a first transmission gear 2304, an upper transmission shaft 2305, a second transmission gear 2306, a driven gear 2307, a transmission chain 2308, a lower transmission shaft 2309, a rotary disk 2310, a first connecting pipe 2314, a regulating cylinder 2315, a valve block 2316, a movable rod 2317, a return pipe 2318, a slider 2319, a chute 2320, an L-shaped connecting column 2321, a second connecting pipe 2322, a liquid supply cylinder 2323, a pressure airbag 2324, a one-way valve 2325, and a liquid supply pipe 2326. A gear mounting plate 2303 is installed on the base 1, and a first transmission gear 2304 is rotatably installed on the gear mounting plate 2303. An upper transmission shaft 2305 is coaxially installed on the first transmission gear 2304, and a second transmission gear 2306 is installed on the end of the upper transmission shaft 2305. A driven gear 2307 is rotatably installed on the cooling box 2302. The driven gear 2307 is connected to the second transmission gear 2306 through a transmission chain 2308. A lower transmission shaft 2309 is coaxially installed on the driven gear 2307. The lower transmission shaft 2309 is located between the partition 2311 and the cooling plate 2312. A turntable 2310 is installed on the end of the lower transmission shaft 2309. A first connecting pipe 2314 is installed on the infusion tube 2313, and a regulating cylinder 2315 is installed on the first connecting pipe 2314. The regulating cylinder 2315 A valve block 2316 is slidably installed in 315, and a moving rod 2317 is installed on the valve block 2316. The moving rod 2317 passes through the partition, and a slider 2319 is installed on the upper end of the moving rod 2317. A slide groove 2320 is provided in the slider 2319. An L-shaped connecting column 2321 is eccentrically installed on the turntable 2310, and the end of the L-shaped connecting column 2321 is slidably installed in the slide groove 2320. A return pipe 2318 is installed on the regulating cylinder 2315 and connected with the infusion tube 2313. A second connecting pipe 2322 is installed on the infusion tube 2313, and a liquid supply cylinder 2323 is installed on the second connecting pipe 2322. A pressure airbag 2324 is installed in the liquid supply cylinder 2323. The liquid supply cylinder 2323 is connected to the liquid inlet pipe 2327 through the liquid supply pipe 2326, and a one-way valve 2325 is installed in the second connecting pipe 2322.

[0029] When the driving motor 12 drives the main gear 14 to rotate, the main gear 14 drives the first transmission gear 2304 to rotate through gear meshing, the first transmission gear 2304 drives the second transmission gear 2306 to rotate through the upper transmission shaft 2305, and the second transmission gear 2306 drives the driven gear 2307 to rotate through the transmission chain 2308. When the driven gear 2307 rotates, the turntable 2310 is driven to rotate synchronously through the lower transmission shaft 2309. The rotation of the turntable 2310 causes the L-shaped connecting column 2321 to drive the slider 2319 to move. Since the L-shaped connecting column 2321 is slidably installed in the slide groove 2320, the L-shaped connecting column 2321 can only drive the slider 2319 to reciprocate in the vertical direction. When the slider 2319 reciprocates, the valve block 2316 is driven to move synchronously through the movable rod 2317. In the initial state, the coolant passes through the first connecting pipe 2313 through the first connecting Tube 2314 flows into the regulating tube 2315 and enters the liquid supply tube 2323 through the second connecting tube 2322. When the valve block 2316 moves downward, the valve block 2316 blocks the first connecting tube 2314. Due to the water hammer effect, the coolant quickly flows into the liquid supply tube 2323, compressing the pressure airbag 2324. At this time, the air pressure in the pressure airbag 2324 increases. When the valve block 2316 moves upward to cancel the blockage, the coolant flows normally, and the water pressure flowing to the liquid supply tube 2323 returns to normal. The pressure airbag 2324 releases the pressure, and the pressure airbag 2324 squeezes the coolant downward, accelerating the coolant to flow into the liquid inlet pipe 2327. With the reciprocating motion of the valve block 2316, this process is repeated, so that the coolant can be input into the spiral cooling tube 2301. At the same time, the change in the stirring frequency will stir the heat generated. The stirring frequency is controlled by the transmission parts to control the cooling liquid supply rate, which can further improve the cooling effect.

[0030] The one-way valve 2325 is a one-way flow valve that can only be opened toward the side close to the pressure airbag 2324 .

[0031] When the pressure airbag 2324 releases pressure downward, it pushes the coolant to flow. Due to the presence of the one-way valve 2325, it is ensured that under the pressure of the pressure airbag 2324, the coolant can only flow to the liquid inlet pipe 2327, ensuring that sufficient power is provided for the flow of the coolant.

[0032] The detection assembly 24 includes a first detection mounting hole 2401, a second detection mounting hole 2402, a detection screw 2403, a second threaded sleeve 2404, a stop hole 2405, a first detection connecting rod 2406, a second detection connecting rod 2407, a detection head 2408, a first detection port 2409, a second detection port 2410, and a control and display component 2412; A first detection mounting hole 2401 is provided in the stirring screw 16, and a second detection mounting hole 2402 is provided in the stirring rod 17. A detection screw 2403 is slidably installed in the first detection mounting hole 2401, and the detection screw 2403 extends into the second detection mounting hole 2402 and is slidably installed with the second detection mounting hole 2402. A second threaded sleeve 2404 is threadedly installed on the upper end of the detection screw 2403. The second threaded sleeve 2404 is located above the fixed plate 21. A stop hole 2405 is provided on the second threaded sleeve 2404. A first detection connecting rod 2406 and a second detection connecting rod 2407 are installed at the lower end of the detection screw 2403. The ends of the first detection connecting rod 2406 and the second detection connecting rod 2407 are both installed with detection heads 2408. A first detection port 2409 and a second detection port 2410 are provided on the stirring rod 17.

[0033] After the stirring is completed, wait for a short time and manually turn the second threaded sleeve 2404. Due to the threaded fit, the stirring screw 16 pushes the first detection link 2406 and the second detection link 2407 to move downward. The first detection link 2406 and the second detection link 2407 will push the detection head 2408 to extend out of the first detection port 2409 and the second detection port 2410 to detect the mixing uniformity of the mixed slurry in the mixing drum 4.

[0034] When the electric telescopic rod 20 is extended, the electric telescopic rod 20 can be extended into the stop hole 2405, which will drive the second threaded sleeve 2404 to rotate synchronously. Since the first detection connecting rod 2406 and the second detection connecting rod 2407 are located inside the stirring screw 16 and the stirring rod 17, during stirring, the second threaded sleeve 2404 and the detection screw 2403 rotate synchronously, and the detection screw 2403 does not move downward.

[0035] The first detection port 2409 is located above the stirring blade 18 on the side close to the upper cover 5 , and the second detection port 2410 is located in the middle of the two stirring blades 18 .

[0036] Usually, the mixture near the stirring blade 18 is stirred more thoroughly. By performing testing on both sides of the stirring blade 18, it is possible to ensure that the test results are more representative and reliable.

[0037] One-way doors 2411 are installed at the first detection port 2409 and the second detection port 2410. The detection head 2408 extends into the detection port. The first detection connecting rod 2406 and the second detection connecting rod 2407 are both bendable elastic plates.

[0038] The elastic plate can push the detection head 2408 out for detection, and can prevent the first detection link 2406 and the second detection link 2407 from getting stuck and making it impossible to extend the detection head 2408. The one-way door 2411 can prevent the slurry from entering the first detection port 2409 and the second detection port 2410 during stirring, thereby improving the accuracy.

[0039] A control and display component 2412 is installed on the base 1. The control and display component 2412 is electrically connected to the pump 10, the electric telescopic rod 20 and the detection head 2408. The electric telescopic rod 20 is electrically connected to the drive motor 12 and the pump 10.

[0040] When the drive motor 12 and the pump are working at the same time, the electric telescopic rod 20 remains in a retracted state to perform feeding and low-speed pre-mixing. When only the drive motor 12 is working, the electric telescopic rod 20 is extended to perform high-speed mixing. The detection head 2408 will transmit the detection data back to the control and display unit 2412, and the worker can judge whether additional stirring is needed based on the data. Working principle of the present invention: Before stirring, carbon nanotubes are added into the mixing drum 4 through the feed port 7, and at the same time, the pump 10 is started to extract the stirring water in the water tank 3. The stirring water enters the water storage layer 8 through the water pipe 11 and flows into the mixing drum 4 from the water outlet 9. Since the water outlet 9 is evenly distributed on the upper cover 5, the stirring water can flow evenly into the mixing drum 4, avoiding the phenomenon of local over-thinness and local over-thickness caused by single-point addition of stirring water, which can speed up subsequent stirring operations and improve mixing uniformity.

[0041] When the pump 10 inputs stirring water into the mixing drum 4, the drive motor 12 is started synchronously to run at a low speed. The drive motor 12 drives the motor gear 13 to rotate. Due to the gear meshing, the motor gear 13 drives the first threaded sleeve 15 to rotate through the main gear 14. The first threaded sleeve 15 causes the stirring screw 16 to reciprocate up and down along the first threaded sleeve 15 through the thread matching. When the stirring screw 16 reciprocates, it drives the stirring blade 18 to move synchronously through the stirring rod 17. The reciprocating movement of the stirring blade 18 will pre-mix the carbon nanotubes and stirring water in the mixing drum 4 at a low speed in the vertical direction, thereby improving the mixing uniformity. After the feeding is completed, the pump 10 and the drive motor 12 both stop working. At this time, the fixed plate 21 is in contact with the first threaded sleeve 15. The drive motor 12 is started again and the electric telescopic rod 20 is controlled to extend. The end of the electric telescopic rod 20 extends into the fixing hole 22. When the drive motor 12 drives the first threaded sleeve 15 to rotate, the stirring screw 16 rotates synchronously with the first threaded sleeve 15 due to the positioning of the electric telescopic rod 20. At this time, the first threaded sleeve 15 and the stirring screw 16 are equivalent to a rigid connection. The first threaded sleeve 15 drives the stirring blade 18 to rotate at a high speed through the stirring screw 16, stirring the mixture at a high speed. The mixing uniformity is further improved by combining multi-stage mixing of low-speed premixing and high-speed stirring.

[0042] When the mixture is stirred, the coolant flows from the cooling box 2302 through the liquid infusion pipe 2313 and the liquid inlet pipe 2327 into the spiral cooling tube 2301, and finally flows back to the top of the cooling box 2302 from the liquid outlet pipe 2328. After the coolant enters the cooling box 2302 again, the inclined surface of the cooling plate 2312 will flow to the guide hole 2329. After the used coolant is re-cooled by the two cooling plates 2312, the coolant flows back from the partition 2311 into the liquid infusion pipe 2313 for reuse, thereby cooling the mixing drum 4, preventing changes in the properties of the slurry, thereby ensuring product quality, and at the same time realizing the reuse of the coolant and reducing production costs.

[0043] When the driving motor 12 drives the main gear 14 to rotate, the main gear 14 drives the first transmission gear 2304 to rotate through gear meshing, the first transmission gear 2304 drives the second transmission gear 2306 to rotate through the upper transmission shaft 2305, and the second transmission gear 2306 drives the driven gear 2307 to rotate through the transmission chain 2308. When the driven gear 2307 rotates, the turntable 2310 is driven to rotate synchronously through the lower transmission shaft 2309. The rotation of the turntable 2310 causes the L-shaped connecting column 2321 to drive the slider 2319 to move. Since the L-shaped connecting column 2321 is slidably installed in the slide groove 2320, the L-shaped connecting column 2321 can only drive the slider 2319 to reciprocate in the vertical direction. When the slider 2319 reciprocates, the valve block 2316 is driven to move synchronously through the movable rod 2317. In the initial state, the coolant passes through the first connecting pipe 2313 through the first connecting Tube 2314 flows into the regulating tube 2315 and enters the liquid supply tube 2323 through the second connecting tube 2322. When the valve block 2316 moves downward, the valve block 2316 blocks the first connecting tube 2314. Due to the water hammer effect, the coolant quickly flows into the liquid supply tube 2323, compressing the pressure airbag 2324. At this time, the air pressure in the pressure airbag 2324 increases. When the valve block 2316 moves upward to cancel the blockage, the coolant flows normally, and the water pressure flowing to the liquid supply tube 2323 returns to normal. The pressure airbag 2324 releases the pressure, and the pressure airbag 2324 squeezes the coolant downward, accelerating the coolant to flow into the liquid inlet pipe 2327. With the reciprocating motion of the valve block 2316, this process is repeated, so that the coolant can be input into the spiral cooling tube 2301. At the same time, the change in the stirring frequency will stir the heat generated. The stirring frequency is controlled by the transmission parts to control the cooling liquid supply rate, which can further improve the cooling effect.

[0044] When the pressure airbag 2324 releases pressure downward, it pushes the coolant to flow. Due to the presence of the one-way valve 2325, it is ensured that under the pressure of the pressure airbag 2324, the coolant can only flow to the liquid inlet pipe 2327, ensuring that sufficient power is provided for the flow of the coolant.

[0045] After the mixing is completed, wait for a short time and manually turn the second threaded sleeve 2404. Due to the threaded fit, the mixing screw 16 pushes the first detection link 2406 and the second detection link 2407 to move downward. The first detection link 2406 and the second detection link 2407 will push the detection head 2408 to extend the first detection port 2409 and the second detection port 2410 to detect the mixing uniformity of the mixed slurry in the mixing drum 4.

[0046] When the electric telescopic rod 20 is extended, the electric telescopic rod 20 can be extended into the stop hole 2405, which will drive the second threaded sleeve 2404 to rotate synchronously. Since the first detection connecting rod 2406 and the second detection connecting rod 2407 are located inside the stirring screw 16 and the stirring rod 17, during stirring, the second threaded sleeve 2404 and the detection screw 2403 rotate synchronously, and the detection screw 2403 does not move downward.

[0047] Usually, the mixture near the stirring blade 18 is stirred more thoroughly. By performing testing on both sides of the stirring blade 18, it is possible to ensure that the test results are more representative and reliable.

[0048] The elastic plate can push the detection head 2408 out for detection, and can prevent the first detection link 2406 and the second detection link 2407 from getting stuck and making it impossible to extend the detection head 2408. The one-way door 2411 can prevent the slurry from entering the first detection port 2409 and the second detection port 2410 during stirring, thereby improving the accuracy.

[0049] When the drive motor 12 and the pump are working at the same time, the electric telescopic rod 20 remains in a retracted state to perform feeding and low-speed pre-mixing. When only the drive motor 12 is working, the electric telescopic rod 20 is extended to perform high-speed mixing. The detection head 2408 will transmit the detection data back to the control and display unit 2412, and the worker can judge whether additional stirring is needed based on the data. It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be included therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
