Description

Technical Field

[0001] This utility model relates to the field of separation and purification technology, and in particular to an automated purification and separation device for fullerene production. Background Technology

[0002] Fullerenes are elemental substances composed of carbon atoms, belonging to the third allotrope of carbon (the other two being graphite and diamond). Their molecules have a hollow, cage-like structure, and their shapes include spherical, ellipsoidal, or tubular (such as carbon nanotubes). Depending on the number of carbon atoms, they can be classified into various types such as C20, C60, and C70. Among these, C60 has been the most studied due to its high symmetry and stability. In the production of fullerenes, C60 needs to be extracted from the mixture, thus requiring the use of separation and purification equipment.

[0003] Chinese Patent CN221889292U discloses a fullerene separation and purification device. This device uses a multi-position intermittent liquid feeding mechanism. When the motor is started, the stirring shaft drives the stirring blades to rotate in both directions, and at the same time, it drives the rotating disk to rotate. When the through hole is intermittently aligned with the bottom of each diversion pipe, the fullerene solution enters through the fullerene solution feed hopper and can intermittently fall onto multiple positions on the surface of the filter screen, making the surface area of ​​the filter screen large. In addition, the scrapers connected to the two connecting rods can rotate along the surface of the filter screen and clean the impurities intercepted on the surface of the filter screen, effectively preventing the filter screen from becoming impermeable.

[0004] However, the device still has shortcomings: the scraper cannot remove the blockages in the filter screen pores, and the device lacks a structure for automatically separating impurities. Although the scraper only disperses impurities on the surface of the filter screen, these impurities will still fall back onto the filter screen. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background technology by proposing an automated purification and separation device for fullerene production.

[0007] The top of the separation filter cartridge is inserted into the guide hopper and rotated coaxially with it. The bottom of the separation filter cartridge is integrally connected to the collection hopper. The output end of the collection hopper is rotatably connected to the discharge pipe with a second valve. The output end of the discharge pipe extends out of the separation tank.

[0009] A stirrer is installed inside the separation tank and below the separation filter cartridge;

[0010] The drive assembly is installed on the separation tank. In the working state, the drive assembly drives the stirrer and the separation filter cylinder to rotate, and drives the piston plate to slide back and forth along the radial direction of the separation filter cylinder while the piston plate follows the rotation of the separation filter cylinder.

[0011] An air blowing hood is installed inside the separation tank and slides in contact with the outer arc surface of the separation filter cartridge.

[0012] And an air supply component, the output of which is connected to the input of the air blowing hood.

[0013] Preferably, the air supply assembly includes an air compressor and an air tank. A base is provided at the bottom of the separator tank, and both the air compressor and the air tank are mounted on the base. The output end of the air compressor is connected to the input end of the air tank, and an air outlet pipe is provided at the output end of the air tank. The other end of the air outlet pipe is inserted into the air blowing hood.

[0014] Preferably, a number of guide rails are arranged in a ring array around the axis on the arc-shaped inner wall of the separator filter cartridge, and a number of guide grooves are provided on the piston plate. Each guide rail is inserted into the guide groove on the corresponding side and is slidably connected to its inner wall.

[0015] Preferably, the agitator includes a stirring shaft and a stirring paddle, a fixing frame is provided on the inner wall of the separation filter cylinder, the top end of the stirring shaft is inserted into the separation filter cylinder and coaxially connected to the fixing frame, and the stirring paddle is disposed on the stirring shaft.

[0018] Compared with the prior art, the present invention has the following beneficial technical effects:

[0019] By installing a piston plate that slides radially inside the separator filter cartridge and by installing a drive assembly that drives the separator filter cartridge to rotate, the piston plate is driven to reciprocate up and down while rotating with the separator filter cartridge. The reciprocating piston plate can scrape and clean the inner wall of the separator filter cartridge. By installing a feed pipe with a third valve on the piston plate, the valve opens when the piston plate moves upward, facilitating the downward conveying of raw materials falling above the piston plate, thus ensuring the normal operation of the filtration process. When the piston plate moves downward and impurities need to be removed, the third valve closes to prevent the mixed liquid from being discharged along the discharge pipe. By installing an agitator that is linked with the drive assembly, the energy consumption of the entire device is reduced. At the same time, this utility model also includes an air supply assembly that blows air from the outside of the separator filter cartridge to its inside. By blowing air, impurities inside the filter holes are blown into the separator filter cartridge, further improving the permeability of the filter holes. Attached Figure Description

[0024] Example 1

[0025] like Figures 1-3As shown, this utility model proposes an automated purification and separation device for fullerene production, comprising a separation tank 2, a separation filter cartridge 5, a piston plate 10, a stirrer, a drive assembly, an air blowing hood 19, and an air supply assembly. The separation tank 2 is equipped with a feed hopper 3 and a discharge pipe 201 with a first valve 2011. A guide hopper 4 is installed inside the separation tank 2. The top of the separation filter cartridge 5 is inserted into the guide hopper 4 and rotatably connected to it coaxially. The bottom of the separation filter cartridge 5 is integrally connected to a collecting hopper 6. The output end of the collecting hopper 6 is rotatably connected to a discharge pipe 7 with a second valve 71, and the output end of the discharge pipe 7 extends outside the separation tank 2. The collecting hopper 6 is a transparent hopper, and a transparent observation window of the same height as the collecting hopper 6 is provided on the separation tank 2. A piston plate 10 is disposed inside the separation filter cylinder 5 and slides radially therein. A feed guide pipe 11 with a third valve 111 is disposed on the piston plate 10. A filter screen is disposed at one end of the feed guide pipe 11 near the collecting hopper 6. The first valve 2011, the second valve 71, and the third valve 111 are all solenoid valves. Several guide rails 51 are arranged in a circular array around the axis of the arc-shaped inner wall of the separation filter cylinder 5. Several guide grooves are disposed on the piston plate 10. Each guide rail 51 is inserted into the guide groove on its corresponding side and slidably connected to its inner wall. A stirrer is disposed inside the separation tank 2 and located below the separation filter cylinder 5. The stirrer includes a stirring shaft 13 and a stirring paddle 14. A fixing frame 52 is disposed on the inner wall of the separation filter cylinder 5. The top end of the stirring shaft 13 is inserted into the separation filter cylinder 5 and coaxially connected to the fixing frame 52. The stirring paddle 14 is disposed on the stirring shaft 13. A drive assembly is disposed on the separation tank 2. The drive assembly includes a guide pipe 8, a movable rod 9, a reciprocating screw 12, and a motor 17. A guide tube 8 is mounted on the upper wall of the inner cavity of the separator tank 2. A movable rod 9 is coaxially rotatably connected to a piston plate 10. The end of the movable rod 9 away from the piston plate 10 is inserted into the guide tube 8 and slides radially therein. A reciprocating screw 12 is rotatably mounted on the separator tank 2. The reciprocating screw 12 is inserted into the guide tube 8 and coaxially rotatably connected to it. The sliding end of the reciprocating screw 12 is connected to the movable rod 9. The motor 17 is mounted on the separator tank 2. The output end of the motor 17 is connected to the reciprocating screw 12. The end of the reciprocating screw 12 away from the motor 17 is connected to the fixed frame 52. In operation, the drive assembly drives the stirrer and the separator filter cartridge 5 to rotate, and simultaneously drives the piston plate 10 to reciprocate radially along the separator filter cartridge 5 while the piston plate 10 rotates with the separator filter cartridge 5. An air blowing hood 19 is mounted inside the separator tank 2 and slides in contact with the outer arc surface of the separator filter cartridge 5. The output end of the air supply assembly is connected to the input end of the air blowing hood 19. The air supply assembly includes an air compressor 20 and an air tank 21. A base 1 is provided at the bottom of the separator 2. Both the air compressor 20 and the air tank 21 are mounted on the base 1. The output end of the air compressor 20 is connected to the input end of the air tank 21. An air outlet pipe 18 is provided at the output end of the air tank 21. The other end of the air outlet pipe 18 is inserted into the air blowing hood 19.

[0026] In this embodiment, the motor 17 is started, driving the reciprocating screw 12 to rotate, thereby keeping the separator filter cartridge 5 rotating. Simultaneously, the piston plate 10 reciprocates and rises and falls along with the separator filter cartridge 5. The air compressor 20 is started, injecting air into the air storage tank 21. When the air pressure in the air storage tank 21 reaches a certain value, the air compressor 20 stops working. The air storage tank 21 blows air into the air blowing hood 19 through the air outlet pipe 18. The filter holes of the separator filter cartridge covered by the air blowing hood 19 are flushed by the high-pressure airflow. Raw materials and xylene solvent are added to the separator tank 2 along the feed hopper 3. The main impurities in the raw materials fall into the separator filter cartridge 5, while a small amount of fine impurities clog the filter holes of the separator filter cartridge 5. As the separator filter cartridge 5 rotates, the clogged holes spiral into the opening of the air blowing hood 19, and the high-pressure airflow blows open the clogged impurities, ensuring the separator filter cartridge 5 efficiently separates and filters impurities from the mixed raw materials. By visually inspecting the accumulation of impurities in the collection hopper 6, the second valve 71 is opened in real time when the piston plate 10 slides down into the collection hopper 6. The opening of the second valve 71 automatically discharges the impurities in the collection hopper 6 along the discharge pipe 7. Then, when the piston plate 10 slides up and is about to leave the collection hopper 6, the second valve 71 is closed, thereby reducing the amount of effective mixed liquid discharged along the discharge pipe 7 and thus avoiding excessive waste.

[0027] Example 2

[0028] like Figure 2 and Figure 3 As shown, the present invention proposes an automated purification and separation device for fullerene production.

A support rod 15 is provided on the stirring shaft 13, and the heating rod 16 is connected to the support rod 15. The temperature sensor is set on the separation tank 2 and located below the liquid surface. The controller is a PLC controller, which is set on the separation tank 2 and electrically connected to both the temperature sensor and the heating rod 16.

[0029] In this embodiment, the heating rod 16 is mounted on the stirring shaft 13. The heating rod 16 rotates synchronously with the stirring shaft 13, which can improve the heating efficiency of the mixture. The heating rod 16, which rotates with the stirring shaft 13, can also perform high-frequency shearing on the mixture, thereby improving the mixing efficiency of the raw materials and the uniform temperature dispersion efficiency. At the same time, the temperature sensor is used to measure the temperature of the mixture in real time, and the heating power and start / stop of the heating rod 16 are controlled by the controller.

[0031] This utility model proposes an automated purification and separation device for fullerene production. Compared with Embodiment 1, a dry-wet separator (located on the back side of the air compressor 20, not shown) is installed on the base 1. The dry-wet separator is a screw extrusion type dry-wet separator. The dry material output end of the dry-wet separator is connected to the outside, and the wet material output end of the dry-wet separator is connected to a liquid pump (conventional structure, not shown). A return pipe is installed at the output end of the liquid pump. The return pipe is inserted into the feed hopper 3, and the output end of the discharge pipe 7 is connected to the input end of the dry-wet separator.

[0032] In this embodiment, a dry-wet separator is used to separate the mixture discharged from the discharge pipe 7 into dry and wet components. The main impurities are squeezed dry and removed, and the wet material is recycled to reduce the waste of the mixture.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
