Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of nano material processing, and particularly relates to a dispersion device for single-walled carbon nanotubes. Background Art
[0002] Single-walled carbon nanotubes have strong van der Waals forces (about 500eV / µm), which makes them easily attracted to each other and aggregated together to form large bundles. In order to better apply single-walled carbon nanotubes in various fields (such as nanoelectronic devices, energy storage devices, structural and functional composite materials, etc.), they need to be chemically functionalized. However, agglomerated carbon nanotubes are difficult to effectively chemically modify, so they need to be dispersed into single tubes or small bundles first.
[0003] During the processing of single-walled carbon nanotubes (SWCNTs), the performance of the dispersion device plays a critical role in the dispersion effect. However, conventional SWCNT dispersion devices have significant drawbacks. During the dispersion process, the dispersion disc often disperses the material to the inner edge of the dispersion barrel. This results in uneven material distribution, with some materials being fully dispersed while others are poorly dispersed, resulting in variable overall dispersion results. This uneven dispersion not only affects product quality and performance but also increases the difficulty and cost of subsequent processing.
[0004] Therefore, in order to solve the above problems, it is necessary to design a dispersion device for single-walled carbon nanotubes. Utility Model Content

[0044] In this embodiment, the single-walled carbon nanotube material to be dispersed is added to the dispersion barrel 2, and the rotating shaft 301 and the dispersion disk 302 are driven to rotate. The dispersion disk 302 generates shear force and impact force during the rotation process to preliminarily disperse the material.

After multiple cycles of dispersion and airflow disturbance, the material gradually reaches a uniformly dispersed state. Through the above steps, the effects of reducing material accumulation, improving dispersion uniformity and improving dispersion efficiency are achieved.
[0045] The driving assembly 3 also includes: a bearing seat 303 mounted on the outside of the rotating shaft 301, a shell 304 arranged on the top of the bearing seat 303, and a motor 305 arranged on one side of the shell 304; wherein the motor 305 is suitable for driving the rotating shaft 301 to rotate; wherein the bearing seat 303 functions to support and fix the rotating shaft 301, ensuring that the rotating shaft 301 can rotate stably and smoothly; wherein the motor 305 adopts but is not limited to a servo motor.
[0046] The driving assembly 3 also includes: a first transmission wheel 306 mounted on the rotating shaft 301, a second transmission wheel 307 mounted on the motor 305, and at least one transmission belt 308 wound around the outside of the first transmission wheel 306 and the second transmission wheel 307; wherein the transmission belt 308 is suitable for transmitting between the first transmission wheel 306 and the second transmission wheel 307; when the motor 305 is started, the output shaft of the motor 305 drives the second transmission wheel 307 to rotate, and the second transmission wheel 307 transmits power to the first transmission wheel 306 through the transmission belt 308, and the first transmission wheel 306 rotates accordingly, and drives the rotating shaft 301 and the dispersion disk 302 to rotate in the dispersion barrel 2.
[0047] The support frame 1 is provided with a telescopic member 5; wherein the top of the telescopic member 5 is connected to the bottom of the shell 304; and the telescopic member 5 is suitable for driving the rotating shaft 301 and the dispersion disk 302 away from the dispersion barrel 2 when extended; wherein the telescopic member 5 adopts but is not limited to an electric cylinder, an air cylinder or a hydraulic cylinder; wherein when it is necessary to adjust the height of the dispersion disk 302, the telescopic member 5 is controlled to extend, and at this time the telescopic member 5 drives the shell 304, the rotating shaft 301 and the dispersion disk 302 to rise. By adjusting the height of the dispersion disk 302, it is convenient to replace materials, clean the dispersion barrel 2 or maintain the drive component 3, thereby reducing maintenance costs and time. At the same time, according to the properties of the material and the dispersion requirements, the distance between the dispersion disk 302 and the material in the dispersion barrel 2 can be adjusted to optimize the dispersion effect.
[0048] The support frame 1 is provided with a fixing plate 6, which is sleeved onto the outside of the telescopic member 5.

This ensures the stability and accuracy of the drive assembly 3 during the lifting process. The guide post 7 also supports the housing 304 and the dispersion plate 302, preventing them from tilting or deforming during the lifting process.
[0049] A clamping bracket 8 is provided on the side of the support frame 1; two screw rods 9 are threadedly engaged on the clamping bracket 8; a clamping piece 10 is provided at one end of the screw rod 9; the two clamping pieces 10 are suitable for clamping and fixing the dispersion barrel 2.

The handle 11 is continued to be rotated to increase the clamping force of the clamping member 10 on the dispersion barrel 2 until the dispersion barrel 2 is firmly fixed on the support frame 1, and the drive assembly 3 is started to perform the dispersion operation.
