Description

Technical Field

[0001] This utility model relates to the field of impurity separation technology, specifically a low-speed centrifugal separation device for amorphous carbon impurities in nanoparticles. Background Technology

[0002] In the purification process of single-walled carbon nanotubes, low-speed centrifugation is often used. Due to the differences in density and shape between amorphous carbon impurities and single-walled carbon nanotubes, amorphous carbon impurities typically have lower density and different shapes than single-walled carbon nanotubes. This results in different trajectories and deposition locations under centrifugal force. Lower centrifugation speed is sufficient to separate these lighter amorphous carbon impurities from the heavier single-walled carbon nanotubes, because these impurities will move outward and deposit in different areas under lower centrifugal force, while single-walled carbon nanotubes, due to their higher density and different structural properties, remain in place or move a shorter distance under the same centrifugal force.

[0003] However, when a large number of raw materials are separated at the same time, single-walled carbon nanotubes and amorphous carbon impurities are stacked together. The separation action relies entirely on the difference in the force exerted by centrifugal force on the two particles. The single-walled carbon nanotubes and amorphous carbon impurities themselves will form mutual obstacles, affecting the separation effect. Utility Model Content

[0048] 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.

[0049] Please see Figures 1-7 In this embodiment of the present invention, a low-speed centrifugal separation device for amorphous carbon impurities in nanoparticles includes a separation tank 1, a support structure 2, a capping structure 3, an internal support 4, and a sieving structure 5.

The support structure 2 consists of two sets, which are rotatably connected to both sides of the tank body 101. The capping structure 3 is movably engaged with the upper opening of the tank body 101. The internal support 4 includes a bearing 401, and the outer ring of the bearing 401 is slidably engaged with the inner wall of the tank body 101. The sieving structure 5 includes a fixed edge 501, the outer surface of which is fixedly connected to the inner ring of the bearing 401.

[0050] Specifically, the raw material is fed into the screening structure 5, and the opening of the separation tank 1 is closed by the sealing structure 3. At the same time, centrifugal separation is performed by rotating the screening structure 5. The rotation along the fixed axis 501 drives each lifting slider 503 to make a circular motion and slide on the upper surface of each lifting slide plate 104. Guided by the lifting slide plate 104, part of the support structure 4 and the screening structure 5 continuously lift and fall at a certain frequency. The specific frequency changes with the rotation speed. While performing centrifugal separation, the nanoparticles inside the screening structure 5 can also be continuously turned over, improving the screening efficiency and thus improving the screening effect. Example 1

[0051] like Figure 5 As shown, in this embodiment, the separation tank 1 also includes a funnel 102 and a movable chute 103. The funnel 102 is fixedly installed at the bottom opening of the tank body 101. There are several movable chute 103s, which are opened at equal angles on the inner wall of the opening of the tank body 101.

[0052] In this embodiment, the sieved particles enter the gap between the tank 101 and the nano-sieve 502, and are guided out by the funnel 102.

[0054] In practice, the particles that have not passed through the nano-screen 502 are first lifted by the electric push rod 205 to open the opening on the tank 101. Then, the No. 1 motor 203 is started, and the entire separation tank 1 is deflected through the support shaft 201 to tilt the particles in the screening structure 5 for easy discharge. Example 2

[0055] Based on Example 1, in order to supplement the specific movement mode of each internal connecting structure when the support structure 4 and the screening structure 5 move up and down inside the separation tank 1, which were not mentioned in Example 1.

[0056] like Figure 5-7 As shown, in this embodiment, the internal support 4 further includes a movable slider 402, a sealing edge 403, a top support 404, a drive shaft 405, a snap-fit ​​groove 406, a limiting slide plate 407, and a bottom support 408. The movable sliders 402 are numerous and are arranged at equal angles and fixedly installed on the outer surface of the outer ring of the bearing 401. The movable sliders 402 are slidably snapped into the movable groove 103. The sealing edge 403 is fixedly installed on the upper surface of the outer ring of the bearing 401. The outer surface of the top support 404 is fixedly connected to the inner side of the sealing edge 403. The upper end of the drive shaft 405 is movably connected to the middle of the top support 404. The snap-fit ​​groove 406 is opened at the upper end of the drive shaft 405, and the snap-fit ​​groove 406 and the snap-fit ​​end 304 are snapped into each other. The limiting slide plate 407... The number of 07 is several, and several limiting slide plates 407 are arranged at equal angles and fixedly installed on the lower edge of the side surface of the drive shaft 405; the middle part of the bottom support 408 is rotatably connected to the lower end of the drive shaft 405, and the outer surface of the bottom support 408 is fixedly connected to the inner wall of the lower opening of the tank 101; the screening structure 5 also includes a nano screen 502, a slide block 504 and a limiting slide groove 505, the upper opening of the nano screen 502 is fixedly connected to the bottom side of the fixed edge 501; the slide block 504 is fixedly installed on the bottom side of the nano screen 502, and the middle part of the slide block 504 is slidably sleeved with the lower end of the drive shaft 405; the number of limiting slide grooves 505 is several, and several limiting slide grooves 505 are arranged at equal angles and opened on the inner wall of the slide block 504, and the limiting slide grooves 505 are slidably engaged with the limiting slide plates 407.

[0057] In specific implementation, when the cover plate 301 and the opening on the tank body 101 are closed, the snap-fit ​​end 304 and the snap-fit ​​groove 406 snap into each other, so that the second motor 302 can drive the drive shaft 405 to rotate. Then, through the snap-fit ​​of the limiting slide plate 407 and the limiting slide groove 505, the nano-sieve 502 is driven to rotate inside the tank body 101 to perform centrifugal separation. When the lifting slider 503 slides on the upper surface of the lifting slide plate 104, the movable slider 402 slides up and down in the movable slide groove 103, giving the bearing 401 the ability to move up and down. At the same time, the limiting slide plate 407 and the limiting slide groove 505 slide and snap into each other, while maintaining the transmission, giving the slide 504 the ability to slide up and down on the side surface of the drive shaft 405, providing conditions for the up and down movement of the nano-sieve 502.
