Description

Technical Field

[0001] The present invention relates to the field of carbon nanotube electrospinning, and specifically to an electrospinning production device and preparation method for a carbon nanotube composite electrode. Background Art

[0002] Most carbon nanotube composite electrodes are used as electrode materials for zinc-ion batteries. The scarcity and cost problems of lithium metal resources have prompted an urgent need to develop new secondary battery systems that are affordable, environmentally friendly, and have high energy density. Aqueous zinc-ion batteries have low cost, high safety, a low redox potential (-0.76 V SHE. H), and a high theoretical specific capacity of the zinc negative electrode (820 mAh g-1), and thus have become the most competitive alternative to lithium-ion batteries. Therefore, carbon nanotube composite electrodes play an extremely important role in the preparation of zinc-ion batteries.

[0003] In a document with the publication number: CN107503000A, a method for preparing nanofiber carbon filaments by electrospinning is proposed. The method states that "by adjusting the concentration of a suitable polyacrylonitrile solution, high-orientation nanofibers are prepared through a fluid-assisted electrospinning process, and then the obtained nanofibers are post-drawn, and finally high-temperature carbonization is carried out in an inert atmosphere to obtain nanofiber carbon filaments". The method involves high-temperature modification of the nanofibers. However, precise control of the temperature during high-temperature modification is crucial. If the temperature is too high, the fiber structure may be damaged, and if the temperature is too low, the expected performance improvement effect may not be achieved. At the same time, the atmosphere control during the heat treatment process also affects the surface chemical properties and microstructure of the material.

[0004] Laboratory-scale electrospinning equipment has a low output and is difficult to meet the requirements of industrial large-scale production. To achieve large-scale production, it is necessary to develop efficient spinning equipment, such as multi-nozzle spinning systems, continuous spinning devices, etc. However, the design and manufacture of these devices need to consider issues such as mutual interference between multiple nozzles, uniform supply of the solution, and continuous collection of fibers, and the technical difficulty is relatively large; When the nanofibers in electrospinning are initially formed, burrs extend from their surfaces, which will have a certain impact on subsequent annealing and the application of the electrodes.

The solution in the infusion tube is ejected through the nozzle for spinning, and V 2 O 3 is confined in the carbon nanotubes; The spinning disk rotates to collect the ejected spun fibers. The spun fibers are collected by rotating through a guide screw rod with a diameter of 0.5 cm and a length of 10 - 15 cm. They pass through the first guide roller and the second guide roller in an "S" - shaped trajectory. When passing through the burr - removing mechanism, the burrs on the edge of the nanofibers after spinning are removed, and then they pass through the third guide roller and the fourth guide roller in the same "S" - shaped trajectory for guiding; Select and adjust the corresponding adjustment holes on the adjustment piece according to the thickness diameter of the spun fiber product and pass through them. Then pass through the sleeve hole. The pusher mechanism is activated to sink the insulating ring passing through the nanofibers into the electrolyte chamber for electrochemical annealing. During the V 2 O 3 to V 2 O 5 In the process of electrochemical conversion, the carbon nanotubes can act as a "protective structure" to effectively prevent the formation of by - products, and construct a pea - pod - shaped nitrogen - doped carbon nanotube - coated amorphous V 2 O 5 microsphere independent electrode material; The nanofibers that have completed electrochemical annealing continue to pass through the first guide hole and the second guide hole. The heating wire and the heating fan in the evaporation cover cooperate to operate, forming hot air for rapid drying. The water vapor is discharged through the exhaust fan.

[0018] The dried nanofibers pass through the wire hole and are limited by fitting on the wire roller. The collected drum - type collector or the prepared collector is installed in the rotating rod, and the collector is fixed through the positioning clamping plate. As the rotating rod rotates, the nanofibers are wound up. The beneficial effects of the present invention compared with the prior art are as follows: Firstly, by setting six groups of guiding gears, six groups of spinning disks can be driven to spin, realizing efficient spinning. The spinning mechanism corresponding to the distribution of the spinning disks supplies materials for spinning. The first conductive clip holds the first guide core to conduct electricity, and the second conductive clip holds another guide core on the nozzle. Six groups of second conductive clips hold the nozzle and the first guide core to form six - cycle electric fields, realizing zonal spinning.

[0019] Secondly, the first transmission gear and the first transmission bevel gear on the driving motor rotate synchronously, driving the driving rod and the burr - collecting gear to rotate. When the clamping gear on the driving rod contacts the linkage gear, linkage is realized, driving multiple groups of linkage gears to make the upper cutting blades operate, collecting the debris while removing the burrs.

[0020] Thirdly, the rotation of the outer rotating wheel drives the connecting arm on the first rotating ring to move. The connecting arm disengages from the second rotating ring, driving the six groups of adjusting pieces to expand synchronously. At this time, the nanowires arranged in the adjusting holes can adjust their own tension, and the nanowires can flexibly form a tight or loose state. Through the fixation of the insertion rod and the corresponding card holes, the rotation angle of the first rotating ring on the outer rotating wheel is fixed.

[0021] Fourthly, through the up and down settlement of the nanowires in the sleeve holes of the insulating ring, the nanowires can be immersed in the electrolyte storage tank during production, and electrochemical annealing is completed in cooperation with the electrolyte and the voltages released by the first electrode position and the second electrode position.

[0022] Fifthly, through the operation of the heating wire and the heating fan in the evaporation cover, the heat can be fully and evenly transferred to every direction in the drying chamber. The nanowires located at the periphery of the evaporation cover are dried during the movement through the evaporation of the heat flow, avoiding the moisture of the modified nanoelectrodes from affecting the storage.

Each adjustment piece 545 is of a triangular structure and its edge is arc-shaped. A third pin 548 is provided on the adjustment piece 545 and penetrates through and is connected to a second rotating ring 547. The rotation of the outer rotating wheel 51 drives the connecting arm 542 on the first rotating ring 541 to move. When the connecting arm 542 disengages from the second rotating ring 547, it drives the six groups of adjustment pieces 545 to expand synchronously. At this time, the nanowires arranged in the adjustment holes 546 can adjust their own tensions, and the nanowires can flexibly form a taut or loose state.

[0033] The tension adjustment bin 5 is connected to an annealing bin 6. A second bin door 61 is provided on the annealing bin 6. Opening the second bin door 61 enables the threading of the carbon nanowire thread inside the annealing bin 6. At the lower end inside the annealing bin 6, an electrolyte bin 63 is installed. On both sides of the electrolyte bin 63, a first electrode position 64 and a second electrode position 65 are respectively connected.

[0035] An annealing chamber 6 is connected to a drying chamber 7. A third chamber door 71 is provided on the drying chamber 7. Two groups of exhaust fans 72 are distributed at the top of the drying chamber 7. A filtering mechanism can be set according to the composition of the electrolyte to determine whether it is harmful.

First guide frames 73 and second guide frames 74 are respectively provided on both sides of the drying chamber 7. The first guide frame 73 is connected to the annealing chamber 6 and is provided with six first guide holes 731 distributed in a circular array with the center of the first guide frame 73 as the center.

The operation of the heating wires 77 and heating fans 78 in the drying cover 75 can fully and evenly conduct heat flow in every direction inside the drying chamber 7. When the nanowires located outside the drying cover 75 pass by, the heat flow transpires on the moving nanowires to complete drying.

[0036] A side support body 8 is installed close to the drying chamber 7 on the bottom plate frame. A collection device 9 is provided on the side support body 8.

[0037] Referring to Figures 1 to 21 , the present invention provides a technical solution: an electrostatic spinning production preparation method for a carbon nanowire composite electrode. A ratio solution mixed with V 2 O 3 and nitrogen-doped carbon nanowires is placed into the mixing liquid chamber 2. The mixed liquid is guided into the infusion tube 414 through the infusion pump 103 on the control host 1; The first conductive clip 36 clamps the first guide core 35, and the second conductive clip clamps another guide core on the nozzle to form an electric field. The solution in the infusion tube 414 is sprayed out through the nozzle for spinning, and V 2 O 3 is confined in the carbon nanowires; The spinning disk 34 rotates to collect the ejected spinning, and the spinning wire is collected by a spinning rod with a diameter of 0.5 cm and a length of 10-15 cm, and passes through the first guide roller 421 and the second guide roller 422 in an "S"-shaped trajectory, and the burrs on the edges of the nanowires after spinning are removed by a burr removal mechanism 425; According to the thickness and diameter of the spun product, the corresponding adjustment hole 546 on the adjustment plate 545 is selected and passed through, and then through the sleeve hole 624, the pusher mechanism 62 is opened, and the insulating ring 623 passing through the nanowire is sunk into the electrolyte tank 63 for electrochemical annealing. 2 O 3 To V 2 O 5 During the electrochemical conversion process, carbon nanowires can act as a "protective structure" to effectively prevent the formation of by-products, constructing a pea-pod-shaped nitrogen-doped carbon nanowire-coated amorphous V 2 O 5 Microsphere free-standing electrode materials; The nanowires that have completed electrochemical annealing continue to pass through the first guide hole 731 and the second guide hole 741 . The heating wire 77 and the heating fan 78 in the evaporation cover 75 cooperate to form hot air for rapid drying, and the water vapor is discharged through the exhaust fan 72 .

[0038] The dried nanowires pass through the wire hole 761 and fit onto the upper limit of the wire roller 762. The collected drum collector or the prepared collector is installed in the rotating rod 94 and fixed by the positioning clamp 95. As the rotating rod 94 rotates, the nanowires are wound up.

[0039] Working principle: Before the equipment starts spinning production, the first chamber door 43, the second chamber door 61 and the third chamber door 71 will be opened one by one, and the electrolyte will be injected into the electrolyte chamber 63, that is, the basic preparation for the operation of the equipment before spinning is completed; Mix with V 2 O 3 The original solution of nitrogen-doped carbon nanoparticles is placed in the mixed liquid tank 2, the liquid guide port 202 is connected to the liquid receiving port 104, and the infusion pump 103 pumps the liquid into the infusion tube 414. The capacity of the mixed liquid tank 2 is large and can accommodate more spinning stock solution. The liquid inlet 201 on it can also be directly opened to directly inject and replenish liquid, so as to avoid the injection and replenishment affecting the operation of the equipment; The first servo motor 31 drives the driving gear 32 to rotate, which meshes with and drives the six groups of guiding gears 33 around it to continuously rotate the spinning disks 34 installed on them. When the spinning disks 34 rotate, the air flow generated forms a vortex. The nozzle 413 receives the spinning solution input from the infusion tube 414. The first conductive clip 36 clamps the first guide core 35, and the second conductive clip 415 clamps another guide core on the nozzle 413 to form an electric field. The six groups of spinning mechanisms 41 control the formation of six groups of circulating and relatively independent electric fields. The solution in the infusion tube 414 is ejected through the nozzle 413 for spinning, and the nanofibers spun are concentrated towards the spinning disks 34. A guide wire rod with a diameter of 0.5 cm and a length of 10 - 15 cm is used to collect the rotating filaments near the spinning disks 34. After being pulled, a single filament is formed and gradually tightened as the spinning disks 34 rotate. The formed nanowire passes through the first guide roller 421 and the second guide roller 422 in an "S" - shaped trajectory; Similarly, it then passes through between the second guide roller 422 and the third guide roller 423 in an "S" - shaped trajectory, pushing the pulling tooth plate 4253. The teeth on it contact the unfolding teeth 4257c. When the pulling tooth plate 4253 is pushed to the vertex, the arc - shaped frame 4257b is fully unfolded, and the second limit magnetic sheet 4253b is adsorbed and fixed on the operating table 4252 for upper limit. When the pulling tooth plate 4253 is pulled down to the vertex, the arc - shaped frame 4257b is fully closed, and the first limit magnetic sheet 4253a is magnetically attracted to the operating table 4252 for fixed limit. When the arc - shaped frame 4257b is closed, the linkage gear 4257e at the top is stuck on the clamping gear 4256b installed in the middle of the driving rod 4256. Through the clamping gear 4256b, all the linkage gears 4257e are driven, driving the cutting blades 4257f on the linkage rod 4257d to rotate. The rotation directions of two adjacent cutting blades 4257f are opposite, and the contact between two adjacent cutting blades 4257f directly cuts off the excess burrs; When the arc - shaped frame 4257b is unfolded, it is convenient for threading the carbon nanotubes. When it is closed, the burr - removing mechanism 425 operates. The driving motor 4255 drives the first transmission gear 4255a and the first transmission bevel gear 4255b to rotate. The first transmission gear 4255a drives the burr - collecting gear 4258 to rotate. The driving guide rod 4258a installed inside the burr - collecting gear 4258 drives the collecting fan 4258b to rotate, collecting the removed burr tissues and entering the collecting bag 4258c for collection.

[0040] According to the thickness diameter of the finished nanowire spinning product, select and pass through the corresponding adjustment holes 546 on the adjustment piece 545. When adjusting the tension of the nanowire, rotate the outer runner 51. When fixing the rotation angle of the outer runner 51, pull the pull handle 533, and the insert rod 532 will leave the original clamping hole 52. After the rotation angle of the outer runner 51 is completed, through the resilience of the spring 535, the insert rod 532 can be limited in the existing clamping hole 52. The rotation of the outer runner 51 drives the connecting arm 542 on the first rotating ring 541 to move. The connecting arm 542 disengages from the second rotating ring 547 to complete the rotation, driving the six groups of adjustment pieces 545 to expand synchronously. The nanowire arranged in the adjustment hole 546 can adjust its own tension according to the position of the adjustment piece 545, and can flexibly form a tight or loose state. The nanowire also passes through the sleeve hole 624 and enters the first guide hole 731 synchronously; Precisely control the telescopic dimension of the electric telescopic rod 622 through the control panel 101 and the control button 102 on the control host 1. Immerse the insulating ring 623 on the electric telescopic rod 622 into the electrolyte tank 63. There is electrolyte in the electrolyte tank 63. The voltage released by the first electrode position 64 and the second electrode position 65 with the electrolyte as the medium performs electrochemical annealing on the spun carbon nanowire composite electrode. At V 2 O 3 towards V 2 O 5 During the process of electrochemical conversion, the carbon nanowire acts as a "protective structure", effectively preventing the formation of by-products, and constructing a pea pod-shaped nitrogen-doped carbon nanowire-coated amorphous V 2 O 5 microsphere independent electrode material; The nanowire that has completed electrochemical annealing continues to pass through the first guide hole 731 and the second guide hole 741 and enters the drying chamber 7. The heating wire 77 and the heating fan 78 in the evaporation cover 75 are synchronously turned on and operate in cooperation with each other to form hot air spreading around the evaporation cover 75 to quickly dry the carbon nanowire immersed in the electrolyte. The water vapor is discharged through the exhaust fan 72; The dried nanowire passes through the wire hole 761 and is limited by fitting on the wire roller 762. Take out the collector, insert the collector into the rotating rod 94, and through the threaded connection between the positioning clamp 95 and the rotating rod 94, clamp and fix the collector on the collecting device 9. Install the six groups of collectors one by one together. As the multiple groups of rotating rods 94 rotate, the nanowire is efficiently prepared and electrochemically annealed, and the processed carbon nanowire composite electrode is wound up.

In the process of electrochemical conversion of V2O3 to V2O5, the carbon nanowire acts as a "protective structure" to effectively prevent the formation of by-products, thereby constructing a pea pod-shaped nitrogen-doped carbon nanowire-coated amorphous V2O5 microsphere independent electrode material; The nanowires that have completed the electrochemical annealing continue to pass through the first guide hole (731) and the second guide hole (741), and the heating wire (77) and the heating fan (78) in the steam drying cover (75) cooperate to form hot air for rapid drying, and the water vapor is discharged through the exhaust fan (72); The dried nanowires pass through the wire hole (761) and fit onto the upper limit of the wire roller (762). The collected drum collector or the prepared collector is installed in the rotating rod (94). The collector is fixed by the positioning clamp (95). As the rotating rod (94) rotates, the nanowires are rolled up.
