Description

Technical Field

[0001] The utility model belongs to the technical field of carbon nanotube preparation, and in particular relates to a sealed carbon nanotube slurry preparation device provided with a premixing structure. Background Art

[0002] The carbon nanotubes in the prior art are nanomaterials with high strength, high thermal conductivity and unique optical properties, and are widely used in the fields of electronics, materials, biology, etc. During the preparation process, a stirring mechanism is often required to stir and mix the slurry.

[0003] The Chinese patent with application number CN201921809190.6 discloses a carbon nanotube slurry stirring kettle, comprising a base, a kettle body is rotatably provided at the upper end of the base, a second rotating shaft is vertically provided inside the kettle body, a plurality of stirring mechanisms are provided on the second rotating shaft, the stirring mechanism comprises a sleeve fixed on the second rotating shaft and a first stirring rod hinged on the second rotating shaft and located on the upper and lower sides of the sleeve, a sliding rod is slidably provided inside the sleeve, a spring is connected between one end of the sliding rod and the inner side wall of the sleeve, the other end of the sliding rod extends out of the sleeve and is located inside the kettle body, a connecting rod is hinged on both sides of one end of the sliding rod extending out of the sleeve, the other end of the connecting rod is hinged to the middle part of the first stirring rod, a plurality of through holes are provided on the first stirring rod, a plurality of blades are circumferentially provided on the inner wall of the through hole, a plurality of second stirring rods are provided on the upper and lower sides of the first stirring rod, a feed hopper is provided on both sides of the second motor at the top of the kettle body, and a discharge pipe is provided at the bottom of one side of the kettle body;

[0004] The above prior art realizes that the second motor drives the second rotating shaft so that the rotation directions of the kettle body and the second rotating shaft are opposite, which accelerates the fluidity of the material inside the kettle body and improves the stirring effect. However, in actual use, carbon nanotubes have a very large specific surface area, which means that they have a large surface energy and tend to attract each other through van der Waals forces, thereby aggregating into blocks or having a relatively long diameter, entangled together, and forming agglomerates. If the corresponding raw materials are directly mixed with the corresponding solvents during the stirring process, the materials themselves may agglomerate, which may result in a longer stirring time before they can be evenly mixed. In addition, during the stirring process, the liquid interacts with the stirring rod and the inside of the container, which may generate higher noise, pollute the environment, and affect the operator's hearing, mood, concentration, etc.

[0005] In view of this, the present utility model is proposed. Utility Model Content

[0038] One aspect of the application of this embodiment is as follows: when in use, the bottom plate 1 is first connected to an external corresponding power supply control component, and during the stirring process, liquid can be injected into the stirring box 2, and then the carbon nanotube material to be mixed is placed in the premixing box 7, and the liquid and other raw materials that are not easy to agglomerate in the stirring box 2 can be stirred by starting the first motor 111, and the hollow shaft 4 and the mixing plate 5 can be driven to rotate by the second motor 112, and the mixing plate 5 and the stirring rod 3 rotate in the opposite direction to change the stirring flow direction, thereby improving the stirring and mixing effect;

[0039] When the hollow shaft 4 rotates, the third bevel gear 14 and the linkage rod 13 are driven to rotate by the first bevel gear 113 in the driving assembly 11, and then the fourth bevel gear 15 at the other end of the linkage rod 13 is meshed with the fifth bevel gear 16, thereby driving the premixing and breaking rod 8 to rotate, and the materials inside the premixing box 7 are pre-mixed by the premixing and breaking rod 8, so that the carbon nanotubes that may have originally agglomerated are dispersed, and then the opening and closing mechanism 10 is opened, and the mixing process can be achieved through the connecting pipe 9, so that the materials in the premixing box 7 are slowly mixed with the liquid, thereby increasing the mixing speed and improving the mixing effect, reducing agglomeration, thereby improving the uniformity of stirring and mixing, and reducing the stirring time required due to agglomeration, thereby improving efficiency.

[0040] By providing the premixing box 7, during the process of stirring the slurry, the premixing and breaking rod 8 can be rotated in the premixing box 7 to premix and break the carbon nanotube material to avoid self-agglomeration. At the same time, during the stirring process, the opening and closing mechanism 10 is opened, and the raw materials in the premixing box 7 are slowly fed through the connecting tube 9, thereby increasing the mixing speed and improving the mixing effect, reducing agglomeration, thereby further improving the uniformity of stirring and mixing and relatively improving the stirring efficiency.
