[0002] Graphene oxide is an oxide of graphene and an important derivative of graphene-based materials. Due to its special two-dimensional structure and large specific surface area, graphene oxide is prone to agglomeration during preparation and storage. Agglomerated graphene oxide not only affects its dispersibility but also reduces its performance in practical applications. Agglomerated graphene oxide usually exists in the form of large particles or clumps. These particles or clumps have poor dispersibility in water or other solvents and are difficult to form a uniform dispersion.

[0003] In existing technologies, graphene oxide is generally stirred using a simple stirring structure, but this method is ineffective and makes it difficult to achieve rapid and uniform dispersion of graphene oxide. Utility Model Content

A cover plate is installed on the top of the inverted conical material cylinder, and a feed inlet is provided at the top of the inverted conical material cylinder. The cover plate is located at the feed inlet. An L-shaped frame is fixedly installed on the top of the box body. A motor located above the inverted conical material cylinder is fixedly installed on the inner top wall of the L-shaped frame. A drive shaft is fixedly connected to the motor.

A rotating plate located inside the housing is fixedly sleeved on the outside of the drive shaft. Multiple auxiliary plates are fixedly connected at equal angles to the top of the rotating plate, and each auxiliary plate is fixed to the outside of the drive shaft.

[0008] Preferably, the housing has a rotating cylinder inside, the drive shaft passes through the rotating cylinder but does not contact the rotating cylinder, the rotating plate is located inside the rotating cylinder, and multiple connecting rods are fixedly connected at equal angles between the rotating plate and the rotating cylinder.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Example 1, by Figure 1-2 The present invention relates to a rapid dispersion device for graphene oxide, comprising a housing 1, a discharge pipe 4 fixedly installed on the outside of the housing 1, and a dispersion mechanism 2 and a stirring mechanism 3 provided on the housing 1.

[0026] Specifically, by Figure 3-5The dispersing mechanism 2 includes an inverted conical cylinder 201 fixed to the top of the housing 1. The inverted conical cylinder 201 communicates with the interior of the housing 1. A cover plate 208 is installed on the top of the inverted conical cylinder 201, and a feed inlet 2012 is provided at the top of the inverted conical cylinder 201. The cover plate 208 is located at the feed inlet 2012. An L-shaped frame 206 is fixedly installed on the top of the housing 1. A motor 207 located above the inverted conical cylinder 201 is fixedly installed on the inner top wall of the L-shaped frame 206. A motor 207 is fixedly connected to the motor 207. A drive shaft 203 is connected to the inverted conical material cylinder 201, which passes through the cylinder and is rotatably connected to it. An installation cylinder 2014 located inside the inverted conical material cylinder 201 is fixedly sleeved on the outer side of the drive shaft 203. Multiple crushing blades 2015 are uniformly fixedly connected to the outer side of the installation cylinder 2014. Multiple crushing blades 2013 are uniformly fixedly connected to the inner wall of the inverted conical material cylinder 201. The drive shaft 203 passes through the housing 1 and is rotatably connected to it. A fixed sleeve is attached to the outer side of the drive shaft 203. A rotating plate 2010 is located inside the housing 1. Multiple auxiliary plates 2011 are fixedly connected to the top of the rotating plate 2010 at equal angles. Each auxiliary plate 2011 is fixed to the outside of the drive shaft 203. The multiple auxiliary plates 2011 on the top of the rotating plate 2010 guide the particles to rotate along a specific trajectory, which helps to achieve uniform distribution and effective dispersion of the particles. A rotating cylinder 204 is located inside the housing 1, and the drive shaft 203 passes through the rotating cylinder 2010. 4. The rotating plate 2010 is located inside the rotating cylinder 204 and does not contact the rotating cylinder 204. Multiple connecting rods 209 are fixedly connected at equal angles between the rotating plate 2010 and the rotating cylinder 204. Multiple columns 202 are fixedly connected at equal angles on the outer side of the rotating cylinder 204. Each column 202 has a ball bearing 205 installed at its top end that abuts against the inner top wall of the box 1. When the rotating cylinder 204 rotates, it drives each ball bearing 205 to roll on the inner top wall of the box 1, ensuring the stable rotation of the rotating cylinder 204.

[0027] In operation, the cover plate 208 is first opened, and the agglomerated graphene oxide is fed into the inverted conical cylinder 201 through the feed inlet 2012. Then, the motor 207 is started, driving the drive shaft 203 to rotate, which in turn drives the mounting cylinder 2014 to rotate. At the same time, each of the second crushing blades 2015 rotates and works in conjunction with the first crushing blade 2013 to crush the graphene oxide. Since the top diameter of the inverted conical cylinder 201 is larger than the bottom diameter, the graphene oxide can be fully crushed during its fall inside the inverted conical cylinder 201. The crushed graphene oxide falls onto the rotating plate 2010, and the drive shaft 203 drives the rotating plate 2010 to rotate. Through the connecting rods 209, the rotating cylinder 204 is driven to rotate, causing the graphene oxide to move under the action of centrifugal force and collide with the rotating cylinder 204. This helps to break the agglomeration between particles and disperse them into smaller particles, ultimately achieving rapid and uniform dispersion of graphene oxide.

[0028] Specifically, by Figure 6 The stirring mechanism 3 includes a U-shaped frame 301 fixed to the bottom of the housing 1. The bottom end of the drive shaft 203 is rotatably connected to the U-shaped frame 301. Multiple stirring rods 306, all located inside the housing 1, are fixedly connected to the outside of the drive shaft 203. Two stirring shafts 307 are symmetrically rotatably connected to the U-shaped frame 301. The drive shaft 203 is located on the two stirring shafts 307. Driven gears 302 are fixedly installed on the outside of each of the two stirring shafts 307. A drive gear 303 is fixedly installed on the outside of the drive shaft 203. Driven gears 302 are meshed with transmission gears 303. The top ends of the two stirring shafts 307 extend into the interior of the housing 1. Multiple stirring rods 305, all located inside the housing 1, are fixedly connected to the outer sides of the two stirring shafts 307. The stirring rods 305 and stirring rods 306 are arranged alternately. Sealed bearings 304 are sleeved on the outer sides of the transmission shaft 203 and the two stirring shafts 307. Each sealed bearing 304 is located at the bottom of the housing 1. By setting the sealed bearings 304, the sealing performance of the housing 1 is ensured.

[0029] In operation, when the motor 207 starts, it drives the transmission shaft 203 to rotate, which in turn drives the stirring rod 306 to rotate and stir the graphene oxide. Since both driven gears 302 mesh with the transmission gear 303, they drive the two stirring shafts 307 to rotate, which in turn drives each stirring rod 305 to rotate and stir the graphene oxide again, thus improving the dispersion of the graphene oxide.
