Description
Technical field
The utility model relates to a kind of milling apparatus, relates in particular to a kind of environment-friendly automatic feeding system of three-roller grinder with variable-frequency governor.
Background technology
Three-roll grinder is mainly used in slurries such as various paint, printing ink, pigment, is specially adapted to grind the dispersion viscosity height and the thin product of granularity requirements.This three-roll grinder reaches grinding effect by the surperficial mutual extrusion of three rollers of level and the friction of friction speed.Three-roll grinder has three rollers to be installed on the frame made of iron, needs level to install, and the center in a straight line.But level is installed, or inclination is arranged slightly.The steel roller can hollow, the water flowing cooling.Material adds between central roll and back roller.Because the direction of rotation difference of three rollers (rotating speed from then increase in turn forward), the roller spacing is adjustable, just produces good abrasive action.Material is installed in the preliminary roller front after grinding scraper scrapes.Plant operations personnel need constantly to add slurry in three-roll grinder, continue to produce.
Because the roller of existing three-roll grinder all is directly exposed in the air, and material directly adds from the top between central roll and back roller, slurry on the three-roll grinder is exposed in the air in process of production always, organic matter in the slurry produces a large amount of organic gas, this a large amount of organic gas continues to evaporate in the air of workshop in production process, although organic gas toxicity is very little, but organic gas is an irritative gas, can certain spread effect be arranged to workshop three-roll grinder operating personnel's sense of smell and eyes.
And, has irritating organic gas in process of production, can continue volatilization in the workshop, in order to reduce the stimulation of organic gas to operating personnel, just the ventilation emission-reducing system need be installed in the workshop, and require to realize with big air quantity the quick displacement of workshop air in the unit interval in the ventilation emission-reducing system, corresponding blower motor also needs to select for use high-power, therefore the process of three-roll grinder ground slurry just needs a large amount of energy consumptions of additive decrementation to be used for vented exhaust.
Also will use active carbon in the ventilation emission-reducing system as the gas absorption material, three-roll grinder constantly produces a large amount of organic gas, causes the active carbon of ventilation emission-reducing system to change the frequency height, has increased extra production cost.
Because the roller of three-roll grinder is open structure, after the organic gas volatilization that organic matter produces, slurry production loss is big, the batching accuracy is greatly affected, needing regularly to add organic matter in process of production in three-roll grinder replenishes, entirely by operating personnel's experience, also need to carry out repeatedly viscosity test afterwards and come constantly to be controlled, when replenishing to guarantee the quality of slurry.
The material loading of three-roll grinder needs operating personnel that the charging that just lift to three-roll grinder on the slurry of grinding last time is uncovered, and pour three-roll grinder into, carry out the grinding of next time, move in circles, so could guarantee slurry according to normal abrasive successfully, labor intensity of operating personnel is big, and it is long to wait the time of waiting to lift ground slurry, the inefficiency that grinds, and the cost of labor height that grinds.
