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

[0023] Please see Figs. 1-3 This utility model provides a technical solution: a pilot-scale module for carbon nanotube conductive slurry, including a feeding station 1, a premixing kettle 2, an intermediate kettle 3, a sand mill 4, a homogenizer 5, an electric demagnetizer 6, and a discharge port 7. The premixing kettle 2, the sand mill 4, the homogenizer 5, the electric demagnetizer 6, and the discharge port 7 are interconnected with the intermediate kettle 3 through conduits. The intermediate kettle 3 is distributed in a one-to-one correspondence with the premixing kettle 2, the sand mill 4, the homogenizer 5, and the electric demagnetizer 6.

[0024] The premixing vessel 2 includes a tank 21, a level sensor 22, a feed pump 23, a discharge pump 24, a vent pipe 25, a compressed air pipe 251, nozzles 26, an exhaust pipe 27, a waste gas pipe 271, a motor 28, a rotating shaft 29, and a stirring blade 210. The level sensor 22 is installed inside the tank 21, and the feed pump 23 and discharge pump 24 are fixed to the upper end of the tank 21. The vent pipe 25 is fixed inside the tank 21 and is connected to the compressed air pipe 251 via a conduit. Nozzles 26 are fixed at equal intervals on the vent pipe 25. An exhaust pipe 27 is also fixed to the tank 21. It is connected to the exhaust pipe 271; a motor 28 is also fixed on the tank body 21, and a rotating shaft 29 is fixed to the output end of the motor 28, and stirring blades 210 are fixed at equal intervals on the rotating shaft 29; the lowest end face of the stirring blade 210 is lower than the lower end face of the liquid level sensor 22, and the lowest end face of the stirring blade 210 is higher than the upper end face of the nozzle 26; mass flow meters are installed on the pipes connecting the intermediate vessel 3 to the premixing vessel 2, the sand mill 4, the homogenizer 5 and the electromagnet 6; a cooling jacket is provided on the outside of the intermediate vessel 3, and the cooling jacket of the intermediate vessel 3 is connected to the chilled water inlet pipe 31 and the chilled water outlet pipe 32;

[0025] When using this carbon nanotube conductive slurry pilot-scale module, such as Figs. 1-3As shown, the material from the feeding station 1 can be pumped into the premixing tank 2 by the feed pump 23 in conjunction with the guide pipe. The liquid level sensor 22 can detect the liquid level of the material in the premixing tank 2. When the liquid level of the material contacts the liquid level sensor 22, the motor 28 starts and drives the rotating shaft 29 and the stirring blade 210 to rotate, thereby agitating the material. Since the bottom end of the stirring blade 210 is lower than the bottom end of the liquid level sensor 22, the stirring blade 210 must be in contact with the material when it is working, thus avoiding the stirring blade 210 from spinning idly. During the material mixing process, compressed air is injected into the air pipe 25 through the compressed air pipe 251 and sprayed out through the nozzle 26. The sprayed air can increase the mixing efficiency and electrolysis efficiency of the material. The exhaust pipe 27 and the waste gas pipe 271 facilitate the discharge of waste gas for processing. After the material mixing and processing is completed, the material is discharged by the discharge pump 27. 4. The material can be sent to the intermediate vessel 3 corresponding to the premixing vessel 2 for storage. The material in the intermediate vessel 3 corresponding to the premixing vessel 2 can enter the sand mill 4 for grinding through the conveying mechanism. The ground material is then sent to the intermediate vessel 3 corresponding to the sand mill 4 for storage. The material in the intermediate vessel 3 corresponding to the sand mill 4 can enter the homogenizer 5 for processing through the conveying mechanism. The processed material is then sent to the intermediate vessel 3 corresponding to the homogenizer 5 for storage. The intermediate vessel 3 corresponding to the homogenizer 5 can enter the electrostatic demagnetizer 6 for processing through the conveying mechanism. After processing, the material is sent to the intermediate vessel 3 corresponding to the electrostatic demagnetizer 6 for storage. Finally, the material in the intermediate vessel 3 corresponding to the electrostatic demagnetizer 6 is discharged through the discharge port 7. During the storage of the material in the intermediate vessel 3, the temperature can be controlled through the action of the chilled water inlet pipe 31 and the chilled water outlet pipe 32 to ensure the production quality of the material. This is the working principle of the carbon nanotube conductive slurry pilot-scale module.
