Description

Technical Field

[0001] This utility model relates to the field of carbon nanotube processing, specifically to a drying device for preparing carbon nanotube masterbatch. Background Technology

[0002] Carbon nanotubes are a type of nanomaterial composed of a two-dimensional hexagonal lattice of carbon atoms. During the preparation of carbon nanotubes, they are prepared into masterbatches for use. The carbon nanotubes are concentrated into a paste and discharged. After the carbon nanotube masterbatches are cut, they need to be dried before they can be collected and used.

[0003] Chinese utility model patent 2022209265991 discloses a concentration and drying device for preparing carbon nanotube masterbatch, including a mounting frame. A stirring rack is installed on the left side of the inner top wall of the mounting frame. Symmetrical guide pipes are installed on the left side of the top of the mounting frame, with the bottom ends of the guide pipes connected to the stirring rack. A first motor is installed on the left side of the top of the mounting frame, and a drive rod is installed downward through the mounting frame along the output shaft of the first motor. Stirring rods are installed on both sides of the drive rod. This device guides raw materials into the interior of the stirring rack through the guide pipes. The first motor drives the drive rods and stirring rods to thoroughly stir the raw materials. A control valve discharges the raw materials from the stirring rack and can also guide them into the interior of a support frame. A third motor drives a cutting blade to cut the raw materials. The size of the cut masterbatch can be controlled by controlling the rotation speed of the third motor.

[0004] However, the above equipment has the following shortcomings in actual use: the drying mechanism mainly dries the upper surface, which may result in incomplete drying. At the same time, it is easy to stick to the conveyor belt, which makes it difficult to unload the material and further affects the efficiency and quality of carbon nanotube masterbatch preparation. Utility Model Content

[0005] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a drying apparatus for preparing carbon nanotube masterbatch.

A second motor is installed on the upper part, and a cutting blade is installed at the output end of the second motor. A discharge port is dug at the bottom of the slitting box, and the discharge port is on the same center line as the discharge pipe. A drying box is installed through the right side of the conveying component. Support rods are installed at both ends of the conveying component. A collection box is installed at the end of the conveying component. The conveying component includes a conveyor belt and rollers. The rollers are arranged in pairs and placed left and right. The conveyor belt is wrapped around the rollers and connected by belt drive. A fourth motor is installed at the rear end of the left roller and connected by electric drive. The rollers on both sides are mounted on the support rods and are movably connected.

[0009] Several evenly distributed electric heating elements are laid at the top and bottom of the drying oven. A fan is installed at the top of the drying oven, and an air duct is installed at the output end of the fan. A lever is installed at the middle of the front end of the drying oven, and a third motor is installed at the middle of the front end of the drying oven.

Support feet are installed at the bottom corners of the outer frame.

[0011] In summary, the beneficial effects of this application are as follows:

[0012] 1. By configuring the mixing tank, rotating rod, bearing, support, stirring blades, and scraper, not only can carbon nanotube raw materials be mixed and processed, but the scraper also contacts the inner wall of the mixing tank.

[0024] like Figure 1-6As shown, a drying device for preparing carbon nanotube masterbatch includes a discharge pipe 6 inserted in the middle of the bottom of a mixing tank 1, a conveying assembly 8 laid directly below the mixing tank 1, a slitting box 7 installed below the discharge pipe 6, a second motor 701 installed on the upper right inner end of the slitting box 7, a cutting blade 702 installed at the output end of the second motor 701, a discharge port 703 cut at the bottom of the slitting box 7, the discharge port 703 being on the same center line as the discharge pipe 6, a drying box 10 passing through the right side of the conveying assembly 8, support rods 9 installed at both ends of the conveying assembly 8, and the conveying assembly 8 including a conveyor belt 801 and rollers 802, the rollers 802 being arranged in pairs and placed side by side. The conveyor belt 801 is wrapped around the roller 802 and connected by belt drive. The rollers 802 on both the left and right sides are mounted on the support rod 9 and are movably connected. The collection box 16 is placed at the end of the conveying component 8. Several evenly distributed electric heating elements 13 are laid at the top and bottom of the drying box 10. A fan 11 is installed at the top of the drying box 10. A guide pipe 12 is installed at the output end of the fan 11. A guide plate 17 is inserted on the left side of the top of the collection box 16. The guide plate 17 is tilted to the left and close to the conveying component 8, so that the material is easy to discharge and does not easily stick. The mixing tank 1, the conveying component 8, the drying box 10 and the collection box 16 are all installed in the outer frame 19 in the corresponding positions.

[0025] like Figure 1 , Figure 2 and Figure 4 As shown, feed pipes 2 are inserted into the left and right sides of the top of the mixing tank 1. A rotating rod 3 is suspended in the middle of the mixing tank 1. A first motor 301 is installed at the top of the rotating rod 3 and at the middle of the top of the mixing tank 1. A bearing 302 is laid at the intersection of the rotating rod 3 and the mixing tank 1. Several evenly distributed stirring blades 4 are installed on the rotating rod 3. A bracket 303 is installed on the rotating rod 3 at a position offset from the stirring blades 4. The bracket 303 extends in the opposite direction and is equipped with a scraper 5 to scrape off the raw materials adhering to the inner wall of the mixing tank 1, further promoting the uniform mixing of carbon nanotube raw materials, resulting in clean and thorough discharge and reducing the loss of carbon nanotube raw materials.

[0026] like Figure 2 , Figure 3 and Figure 5 As shown, a lever 14 is installed in the middle of the front end of the drying chamber 10, and a third motor 15 is installed in the middle of the front end of the drying chamber 10. The electric heating element 13 is divided into left and right parts inside the drying chamber 10. The other end of the air duct 12 has two branches that are connected to the electric heating element 13 inside the drying chamber 10. This not only dries the carbon nanotube masterbatch, but also turns the carbon nanotube masterbatch over, enabling it to be thoroughly dried and reducing the possibility of incomplete drying.

[0027] The working principle is as follows:

[0028] In use, various raw materials for preparing carbon nanotubes are fed into the mixing tank 1 through the feed pipe 2. The first motor 301 is started, and the rotating rod 3 drives the stirring blades 4 to stir and mix the carbon nanotube raw materials in the mixing tank 1. At the same time, the scraper scrapes off the raw materials adhering to the inner wall of the mixing tank 1. The valve 601 is opened, and the discharge pipe 6 introduces the mixed carbon nanotube raw materials into the slitting box 7. The second motor 701 drives the cutting blade 702 to rotate, and the cutting blade 702 cuts the carbon nanotube raw materials into masterbatches, which are then fed into the feed box. The output from port 703 is fed onto the conveyor belt 801 of the conveyor assembly 8. A fourth motor 18 is installed at the rear end of the left roller 802 and is electrically driven. The conveyor belt 801 circulates around the roller 802, and the carbon nanotube masterbatch is then fed into the drying chamber 10. The other end of the air duct 12 has two branches that are respectively connected to the electric heating element 13 inside the drying chamber 10. The electric heating element 13 is activated to heat up, and the heat generated by the electric heating element 13 is dissipated into the drying chamber 10 through the air duct 12 by the fan 11. The carbon nanotube masterbatch is divided into left and right parts inside the drying chamber 10. The actuating rod 14 is installed between adjacent electric heating plates on the left and right sides. After the carbon nanotube masterbatch enters the drying chamber, it first undergoes preliminary drying processing by the electric heating plate on the left side. Driven by the conveying assembly 8, it moves from left to right. After the carbon nanotube masterbatch is moved to the middle of the drying chamber 10, the actuating rod 15 and the flipping rod come into contact with the carbon nanotube masterbatch. Driven by the third motor 15, the actuating rod 15 and the flipping rod flip the carbon nanotubes on the conveyor belt. The side to be dried is flipped to the top, and the conveying component 8 continues to move the carbon nanotubes to the right. The electric heating plate on the right side performs deep drying processing on them. When the carbon nanotube masterbatch is transferred to the far right of the conveying component 8, it falls into the collection box 16 under its own gravity. If adhesion occurs, the guide plate 17 will scrape off the carbon nanotube masterbatch and send it into the collection box 16. Finally, the drying process in the preparation and processing of carbon nanotube masterbatch is completed. The carbon nanotube masterbatch can also be collected uniformly for further processing.

[0029] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the utility model involved in this application is not limited to the specific combination of the above-described technical features, but should also cover other technical solutions formed by any combination of the above-described technical features or their equivalents without departing from the inventive concept.
