It has excellent optical, electrical, and mechanical properties. It has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material of the future.

[0003] In the production and processing of graphene slurry, the graphene material needs to be crushed. Airflow crushers are usually used in this process. Traditional airflow crushing equipment often has a short material residence time, resulting in substandard crushing. After the material is discharged, it needs to be reworked several times to meet the demand. Therefore, we proposed an airflow crushing equipment for graphene processing. Summary of the invention

[0006] The pulverizing mechanism comprises a cylindrical pulverizing box, an air outlet, an arc filter plate and a material supporting assembly. The axis of the pulverizing box is parallel to the horizontal plane. The discharge ends of the two high-pressure material pipes are movably connected to the left and right walls of the pulverizing box through bearings. A plurality of air outlets are provided on the side walls of the pulverizing box. An arc filter plate is fixedly installed on the inner wall of the pulverizing box at positions corresponding to the air outlets. A plurality of material supporting assemblies are arranged between the left and right walls of the pulverizing box and are arranged in a ring with the axis of the pulverizing box as a reference.

The discharging pipe is inserted into the through hole in the middle of the bottom wall of the machine body. A connecting ring is fixedly sleeved on the lower side of the outer wall of the discharging pipe. The connecting ring is connected to the lower surface of the machine body through the cylinder. Two discharging holes are symmetrically arranged on the upper part of the side wall of the discharging pipe.

[0008] Preferably, the number of the air outlets is not less than four, the air outlets are opened at an angle, and the extension direction of the air outlets is offset by forty-five degrees relative to the axis of the crushing box, the side wall of the crushing box is provided with a discharge hole, the side wall of the crushing box is provided with an arc-shaped cavity, the arc-shaped cavity is connected to the discharge hole, an arc-shaped plate is inserted in the arc-shaped cavity to form a closure for the discharge hole, a traction motor is installed in the arc-shaped cavity, a rack is fixedly connected to the side of the arc-shaped plate close to the traction motor, the gear at the output end of the traction motor is meshed with the rack, and a positioning block is fixedly connected to the outer wall of the crushing box close to the discharge hole for assisting the connection between the discharge pipe and the discharge hole.

[0009] After the material is fed in and needs to be discharged, the discharge pipe extends into the crushing box. As the powder box rotates, the positioning block is blocked by the discharge pipe, the discharge hole is opposite to the discharge pipe, the high-pressure material pipe is closed, and the arc plate is separated from the discharge hole when the traction motor drives the rack to move. At the same time, the discharge pipe goes deep into the discharge hole until the discharge hole completely enters the crushing box. Then the high-pressure material pipe is opened to only deliver high-pressure gas, and the material crushed by the high-pressure gas is discharged through the discharge pipe.

[0010] Preferably, the material supporting assembly comprises a central axis, a connecting tube, a movable plate, an adsorption strip, a strip hole and a limit block, the central axis is fixedly connected between the left and right walls of the crushing box, the connecting tube is sleeved on the central axis, the movable plate is fixedly connected to the outer wall of the connecting tube, and the side of the movable plate away from the connecting tube is fixedly connected with the adsorption strip, a strip hole is opened in the middle of the connecting tube, a limit block is fixedly connected to the central axis and is in the strip hole, and the arc corresponding to the strip hole is sixty degrees.

[0012] The crushing box is made of engineering plastic. When the adsorption strip is affected by the magnetic adsorption block and contacts the inner wall of the crushing box, it can support the graphene material and lift the powder deposited at the bottom of the crushing box. As the crushing box rotates and leaves the influence of the magnetic adsorption block, the adsorption strip separates from the inner wall of the crushing box, and the powder is released from the top and crushed repeatedly when it passes between two high-pressure material pipes.

[0015] Preferably, the axis of the shuttle block coincides with the axis of the high-pressure material tube, and the inner wall of the guide ring is parallel to the arc surface at the corresponding position of the shuttle block.

[0016] The parallel design helps the material to pass smoothly along with the high-pressure gas, and can guide the material, so that the material has a larger impact range, enhances the material crushing effect, and can further increase the pressure.

[0017] By adopting the above technical solution, the beneficial effects of the present invention are:
