Three-dimensional mixer is the use of mechanical force and gravity, the two or more kinds of powder materials are mixed together, three-dimensional motion mixer can be a variety of materials into a uniform mixture; It can also increase the contact surface area of the material to promote chemical reactions and accelerate physical changes.
Melting, such as the addition of granular solutes to solvents, can accelerate the dissolution and mixing through the action of mixing machinery.
Safe operation knowledge of 3D mixer:
1, three-dimensional mixer installation: place the machine smoothly, install the machine feet, pad flat, so that the mechanical can run freely.
2, the three-dimensional mixer will feed the port to the above, open the feed cover for feeding, feeding is not more than the specified volume, and then close the feed cover, open the motor, the device to operate, if found abnormal on the way, must stop for inspection.
3, before use, the oil must be added to the oil, and then the no-load operation, check whether the fasteners are loose, whether the electrical is normal, whether the machinery is operating normally, if there is an anomaly, repair and debugging.
4, if the viscosity of the liquid to be mixed is not high, it can reach a random mixing state within a short stirring time; If the viscosity is higher, the mixing time is longer.
5, three-dimensional mixer replacement variety must be the hopper inside and outside to wash clean. The main convection diffusion and eddy diffusion caused by the mixing of the dimensional mixer increase the surface area of molecular diffusion between different liquids and reduce the diffusion distance, thus shortening the molecular diffusion time.
6, for the density, composition is different, do not dissolve the liquid, the shear effect of stirring and strong turbulence will tear the density of the liquid into small droplets and make it evenly dispersed to the main liquid. The flow velocity of the liquid produced by the three-dimensional mixer must be greater than the settling velocity of the wave droplet.
7. Requirements for safe operation of 3D mixer:
8, the edge of the operating parts of the cleaning three-dimensional mixer causes safety risks. The dispersion shaft and the impeller of the tip are dispersed at high speed. When rotating at high speed, no gloves are worn. Prevent sleeves, long hair and other rolling accidents in the axle, pour lubricating oil into the tank, according to the requirements, to achieve a reasonable position, pay attention to the constant oil level, while using high-speed dispersion, when rotating in the direction of the impeller, the rotation handle of the three-dimensional mixer must be locked in the rotation process to avoid the accident resulting in the transmission box revolution. After the overhaul, the high-speed dispersion should be a trial run to ensure that there is no fault before use. Requires a moderate viscosity of the pigment paste.
