Description

Technical Field

[0001] This utility model relates to the field of carbon nanotube pulverizing devices, and more particularly to a pulverizing device for oligowalled carbon nanotubes. Background Technology

[0002] In the large-scale processing of oligowalled carbon nanotubes, raw material premixing is a crucial preliminary step to ensure the subsequent pulverization effect. A specialized premixing device is needed to fully wet and initially disperse the carbon nanotube powder with the dispersion medium, breaking down initial agglomerates and laying the foundation for the subsequent fine processing in the air jet mill. This premixing device is also an indispensable component of the entire pulverization system. In existing technologies, oligowalled carbon nanotube premixing devices adapted to air jet milling systems typically employ a fixed connection structure between their power output component and material mixing component. This structure transmits driving force to achieve the stirring and premixing of the raw materials, ensuring that the premixed material can be stably delivered to the air jet mill.

[0003] However, existing devices for premixing oligowalled carbon nanotubes have significant limitations in the connection structure between the power output component and the mixing component. Specifically, the disassembly and assembly process is cumbersome, requiring the use of specialized tools to gradually disassemble multiple fixed components. This not only consumes time but also makes it easy for positioning deviations during disassembly and assembly to affect the accuracy of component fitting, leading to uneven material mixing during subsequent premixing. This causes inconvenience for daily maintenance, replacement of mixing components, and repair work, making it difficult to meet the requirements for efficient premixing and rapid maintenance.

[0004] Therefore, those skilled in the art have provided a device for pulverizing oligowalled carbon nanotubes to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a device for pulverizing oligowalled carbon nanotubes. This device utilizes a quick-release mechanism to precisely engage the connecting end, rotating ring, first retaining ring, and second retaining ring with the mounting part of the stirring paddle and the plug-in block. The threaded rod and the clamping nut provide limiting fixation, while the limiting block provides sliding limitation. The first and second arc-shaped sleeves and the positioning groove provide positioning coordination. This allows for easy disassembly and assembly of the stirring paddle without the need for special tools, ensuring a stable connection after installation. This shortens maintenance and replacement time, prevents displacement and loosening during operation, guarantees the stability of the premixing process, and improves the practicality of the device.

[0006] To achieve the above objectives, this utility model provides the following technical solution: An oligowalled carbon nanotube pulverizing device includes a base, a tank, an inspection door, a feed inlet, a support, a servo motor, a stirring paddle, a controller, a discharge outlet, and a valve. The output end of the servo motor is fixedly connected to a quick-release mechanism. The quick-assembly and disassembly mechanism includes two connecting ends. Insertion cylinders are fixedly connected to both sides of one end of the outer wall of the connecting end. A limit block is fixedly connected to one end of the connecting end. Threaded rods are fixedly connected to both sides of the other end of the outer wall of the connecting end. A clamping nut is threaded to one end of each threaded rod. A rotating ring is rotatably connected to the middle of the outer wall of the connecting end. A first retaining ring is fixedly connected to one end of the outer wall of the rotating ring. A first arc-shaped sleeve is fixedly connected to one end of the outer wall of the first retaining ring. A second retaining ring is fixedly connected to the other end of the outer wall of the rotating ring. A second arc-shaped sleeve is fixedly connected to one end of the outer wall of the second retaining ring. A positioning groove is provided in the middle of one end face of both the first and second arc-shaped sleeves. An installation part is fixedly connected to one end of the stirring paddle. Insertion blocks are fixedly connected to both sides of one end of the outer wall of the installation part. Through the above technical solution, the device achieves precise engagement between the connecting end of the quick-disassembly mechanism, the rotating ring, the first retaining ring, the second retaining ring and the mounting part of the stirring paddle, the plug-in block, the limiting fixation of the threaded rod and the clamping nut, the sliding limit of the limiting block, and the positioning cooperation of the first arc sleeve, the second arc sleeve and the positioning groove. This makes it possible to disassemble and assemble the stirring paddle without special tools, making the operation convenient and the connection stable after installation. This shortens the maintenance and replacement time, avoids displacement and loosening during operation, and ensures the stability of the premixing process. By driving the stirring paddle with two servo motors to achieve reverse rotation, combined with the precise control of the servo motors by the controller, the premixing of the oligowalled carbon nanotube raw material and the dispersion medium is more thorough and uniform, effectively breaking the initial agglomerates and providing high-quality raw materials for the subsequent fine processing of the external airflow pulverizer, thus improving the practicality of the device.

[0007] Furthermore, a tank body is fixedly connected to both sides of the upper surface of the base, an inspection door is opened on one side of the outer wall of the tank body, and a feed inlet is opened on one side of the outer wall of the tank body. The above technical solution provides a stable storage space for raw material premixing, the feed inlet facilitates the rapid addition of raw materials and dispersion media, and the inspection door facilitates subsequent inspection and maintenance of the tank interior, ensuring the smooth operation of the premixing process.

[0008] Furthermore, both ends of the base are provided with brackets, and the upper end of each bracket is provided with a servo motor. One end of the quick disassembly mechanism is fixedly connected to a stirring paddle. The two stirring paddles rotate in opposite directions. A controller is provided on the upper end of one side of one of the brackets. The controller is electrically connected to the servo motor. A discharge port is opened on one side of the middle of the outer wall of the tank. A valve is provided inside the discharge port. Through the above technical solution, the controller can precisely control the operation of the servo motor, the reverse-rotating stirring paddle can enhance the uniformity of raw material mixing, effectively break the initial agglomerates of carbon nanotubes, and the valve and discharge port can flexibly control the output of premixed materials, providing suitable raw materials for subsequent external airflow pulverizing devices.

[0009] Furthermore, one end of each of the first and second retaining rings penetrates one end face of the insertion tube and forms a locking connection with one end of the insertion block, and the rotational locking directions of the first and second retaining rings are opposite. The above technical solution forms a bidirectional reverse locking structure, making the quick disassembly mechanism and the agitator more tightly and reliably connected, effectively preventing loosening during operation.

[0010] Furthermore, the diameter of the threaded rod is consistent with the width of the opening on one side of the outer wall of the first arc-shaped sleeve and the second arc-shaped sleeve, and the openings on one side of the outer wall of the first arc-shaped sleeve and the second arc-shaped sleeve face opposite directions; The above technical solution ensures that the first arc-shaped sleeve and the second arc-shaped sleeve can be accurately fitted onto the threaded rod. The reverse opening design avoids mutual interference between the two and ensures the assembly accuracy of the limiting and fixing structure.

[0011] Furthermore, the diameter of the clamping nut is consistent with the diameter of the positioning groove, and one side of the outer wall of the limiting block is slidably connected to one end of the mounting part; Through the above technical solutions, the clamping nut can be precisely fitted and abutted against the positioning groove, and the limiting block can assist the installation part in quick positioning, improving the positioning accuracy and clamping stability when installing the mixing paddle.

[0012] Furthermore, after the rotating ring rotates at a certain angle, the first retaining ring and the second retaining ring are both engaged with one end of the plug-in block. The first arc-shaped sleeve and the second arc-shaped sleeve are both sleeved on the middle of the outer wall of the threaded rod. The clamping nut is tightened and abuts against one side of the outer wall of the positioning groove. The above technical solution enables rapid assembly and multiple fixation of the stirring paddle and the quick-disassembly mechanism, resulting in a stable connection structure that prevents the stirring paddle from shifting or loosening during high-speed rotation and premixing.

[0013] Furthermore, when the clamping nut is loosened, both the first arc-shaped sleeve and the second arc-shaped sleeve disengage from the threaded rod, and both the first retaining ring and the second retaining ring disengage from one end of the insertion block; The above technical solution can quickly release the fixed relationship between the agitator and the quick disassembly mechanism, and the agitator can be disassembled without special tools, which greatly improves the convenience of equipment maintenance and component replacement.

This makes it possible to disassemble and assemble the stirring paddle without special tools, which is convenient and easy to operate. After installation, the connection is stable, which shortens the maintenance and replacement time, avoids displacement and loosening during operation, ensures the stability of the premixing process, and improves the practicality of the device.

One end of the agitator 8 is fixedly connected to the mounting part 712, and both sides of the outer wall of the mounting part 712 are fixedly connected to the plug-in blocks 713. The device achieves precise engagement between the connecting end 71, rotating ring 76, first retaining ring 77, and second retaining ring 79 of the quick disassembly mechanism 7 and the mounting part 712 and plug-in blocks 713 of the agitator 8. The threaded rod 74 is fixedly positioned by the clamping nut 75, and the sliding limit of the limiting block 73, as well as the positioning cooperation between the first arc-shaped sleeve 78, the second arc-shaped sleeve 710, and the positioning groove 711, thus enabling... The stirring paddle 8 can be disassembled and assembled without special tools, is easy to operate, and has a stable connection after installation. This not only shortens the maintenance and replacement time, but also avoids displacement and loosening during operation, ensuring the stability of the premixing process. The stirring paddle 8 is driven by two servo motors 6 and rotates in opposite directions. Combined with the precise control of the servo motors 6 by the controller 9, the premixing of oligowalled carbon nanotube raw materials and dispersion media is more thorough and uniform, effectively breaking up the initial agglomerates. This provides high-quality raw materials for the subsequent fine processing of the external airflow pulverizer, improving the practicality of the device.

[0020] Reference Figure 3-5The base 1 has a tank 2 fixedly connected to both sides of the upper surface. A maintenance door 3 is opened on one side of the outer wall of the tank 2, and a feed inlet 4 is opened on one side of the outer wall of the tank 2, which provides a stable space for the premixing of raw materials. The feed inlet 4 facilitates the rapid addition of raw materials and dispersion media. The maintenance door 3 facilitates the later inspection and maintenance of the inside of the tank 2, ensuring the smooth progress of the premixing process. Both ends of the base 1 are equipped with brackets 5, and the upper end of each bracket 5 is equipped with a servo motor 6. One end of the quick disassembly mechanism 7 is fixedly connected to a stirring paddle 8. The two stirring paddles 8 rotate in opposite directions. A controller 9 is installed on the upper end of one side of one of the brackets 5. The controller 9 is electrically connected to the servo motor 6. A discharge port 10 is opened on one side of the middle of the outer wall of the tank 2. A valve 11 is installed inside the discharge port 10. The controller 9 can precisely control the operation of the servo motor 6. The stirring paddles 8 rotating in opposite directions can enhance the uniformity of raw material mixing and effectively break the initial agglomerates of carbon nanotubes. The valve 11 and the discharge port 10 can flexibly control the output of premixed materials to provide suitable raw materials for subsequent external airflow pulverizing devices. One end of the first retaining ring 77 and the second retaining ring 79 both penetrate one side of the insertion tube 72 and form a locking connection with one end of the insertion block 713. The rotation and locking directions of the first retaining ring 77 and the second retaining ring 79 are opposite, forming a bidirectional reverse locking and fixing structure, which makes the locking connection between the quick disassembly mechanism 7 and the stirring paddle 8 more tight and reliable, effectively preventing loosening during operation. The diameter of the threaded rod 74 is consistent with the width of the opening on one side of the outer wall of the first arc-shaped sleeve 78 and the second arc-shaped sleeve 710. The openings on one side of the outer wall of the first arc-shaped sleeve 78 and the second arc-shaped sleeve 710 face opposite directions to ensure that the first arc-shaped sleeve 78 and the second arc-shaped sleeve 710 can be accurately fitted onto the threaded rod 74. The reverse opening design avoids mutual interference between the two and ensures the assembly accuracy of the limiting and fixing structure. The diameter of the clamping nut 75 is consistent with the diameter of the positioning groove 711. One side of the outer wall of the limiting block 73 forms a sliding connection with one end of the mounting part 712. The clamping nut 75 can precisely fit and abut against the positioning groove 711. The limiting block 73 can assist the mounting part 712 in quick positioning, improving the positioning accuracy and clamping stability when the stirring paddle 8 is installed. After the rotating ring 76 rotates at a certain angle, the first retaining ring 77 and the second retaining ring 79 are both engaged with one end of the plug-in block 713. The first arc-shaped sleeve 78 and the second arc-shaped sleeve 710 are both sleeved on the middle of the outer wall of the threaded rod 74. The clamping nut 75 is tightened and abuts against one side of the outer wall of the positioning groove 711, realizing the quick assembly and multiple fixation of the stirring paddle 8 and the quick disassembly and assembly mechanism 7. The connection structure is stable and can prevent the stirring paddle 8 from shifting or loosening during the high-speed rotation premixing process. When the tightening nut 75 is loosened, the first arc-shaped sleeve 78 and the second arc-shaped sleeve 710 disengage from the threaded rod 74, and the first retaining ring 77 and the second retaining ring 79 disengage from one end of the plug-in block 713. This can quickly release the fixed relationship between the stirring paddle 8 and the quick disassembly mechanism 7, and the stirring paddle 8 can be disassembled without special tools, greatly improving the convenience of equipment maintenance and component replacement.

[0021] Working principle: The oligowalled carbon nanotube raw material and dispersion medium are fed into the tank 2 through the feed inlet 4. The controller 9 starts and precisely controls the servo motor 6 on the support 5. The servo motor 6 drives the stirring paddle 8 to rotate through the quick disassembly mechanism 7. The connecting end 71 of the quick disassembly mechanism 7 is positioned by the limiting block 73 to assist the mounting part 712 of the stirring paddle 8. After the rotating ring 76 rotates, the first retaining ring 77 and the second retaining ring 79 form a reverse engagement with the insertion block 713 of the mounting part 712.
