[Device Structure]

The main equipment structure of graphene production equipment is high-end intelligent equipment integrated control system of graphene, high shear dispersing mixing batching tank, fine dispersion grinding unit (sodium meter cone grinding), hydraulic vortex cavitation, high shearing Flow ultrasonic device, multi-pipe condenser, ultrasonic storage tank, pressure gauge temperature controller and so on.

【working principle】

Graphene grinding and dispersing machine is a high-end discrete peeling and grinding nano-cone grinding intelligent equipment preparation. The main working principle is a new type of nano-scale dispersion colloid mill. The intelligently controlled stripping mechanical multi-function grinding machine principle is also called high-end intelligence of graphene. Equipment preparation method, its advanced high-end intelligent nano graphene production equipment. The graphene production equipment is added with graphite powder, dispersant or surface modifier and water in a high-speed dispersing and stirring storage tank, and then dispersed and stirred by a high-speed disperser to prepare a graphite solution with good dispersion stability. The pipe enters the finely dispersed grinding chamber through a special pulverizing and cutting and peeling device, and the particles, the brittle mass, the agglomerate and the like in the graphite solution are rapidly dispersed and sheared, and then sucked into the third-stage refining zone and the high shear cutting The area of ??shear pulverization and delamination structure in the area, in the very narrow working aisle, due to the rapid cutting of thousands of sets of moving and static grinding slots and thousands of pairs of shearing blades and shearing blades, resulting in strong friction and Disperse, cut, peel, depolymerize, pulverize, grind, etc. Under the action of mechanical motion and centrifugal force, the stripped graphite is pressed into the cutting and stripping zone for grinding and crushing. The fine grinding distinguishes three grades. The more outwardly, the higher the precision of the first-stage grinding disc, the smaller the pitch, the higher the linear velocity. Long, the more the graphite sheet is peeled off, and the fluid gradually curves toward the radial direction. The velocity of the fluid in each stage changes instantaneously, and is subjected to tens of millions of high-speed shears per minute, strong friction, extrusion grinding, particle pulverization, etc., after passing through the three-stage refining zone and the high-shear cutting zone. After tens of millions of high-speed shearing, grinding and pulverizing, graphite strand molecular chain breakage, sheet cutting tearing, and the like are produced. Then through the high pressure pipe into the hydraulic vortex shear cavitation generator; hydraulic vortex shear cavitation technology is a process in which the graphite solution flows into the vortex low pressure region to form vapor vacuoles, when the internal pressure of the graphite solution is reduced to saturated vapor When the pressure is below, the bubbles formed by the hydraulic shear cavitation process begin to appear and grow, and as time passes, the bubbles expand, grow, compress and collapse. But this process is sexual, less than a thousand and six seconds, the bubble can release huge energy at the moment of rapid collapse, instantaneous local high temperature (1900-5000K) and high pressure (up to 140Mpa-170Mpa), and the speed is about It is a micro-jet with a strong impact force of 50-110 m/s, thus causing a series of phenomena such as cavitation, air noise, vibration and luminescence. The effects of cavitation are usually called hydraulic vortex shear cavitation effects. The graphite sheet is peeled off from the monolayer and multilayer ideal graphene products.

[Process Flow]

First, the graphene production equipment is equipped with a graphite powder, a dispersant or a surface modifier and water for mixing and stirring in a high-shear dispersing mill with a mixing tank, first closing the circulation valve and then opening the storage tank to connect with the dispersion grinding pump. The valve allows the graphite solution to pass through a fine dispersion grinder, a hydraulic shear vortex cavitation and then enter the high shear cyclone ultrasonic hopper through pressure. When the batching tank is empty, the lower connecting valve is automatically closed and the circulation valve is opened to allow the graphite solution to continuously unravel from the circulation to make the graphene single layer multi-layered to the desired effect, and the pressure control, time control and temperature control are designed in the integrated control system. You can also use computer control or touch frequency control or fully automatic control.
