Environment-friendly automatic feeding system of three-roller grinder

Abstract

The invention relates to an environment-friendly automatic feeding system of a three-roller grinder, comprising the three-roller grinder which comprises an iron frame, a front roller, a middle rollerand a back roller which are arranged on the iron frame, and a scraper discharging hopper arranged in front of the front roller; a slurry revolving pan provided with a stirring device is arranged belowthe scraper discharging hopper of the slurry revolving pan, a feeding end of a screw pump is communicated with the bottom of the slurry revolving pan via pipes, the discharging end of the screw pumpis connected with a pipe group, the other port of the pipe group is arranged above the position between the middle roller and the back roller, the stirring device comprises a stirring paddle and a scraping sheet fixed on the hinge of the stirring paddle, the screw pump is provided with a PLC variable frequency governor, the pipe group is constructed by at least three demountable pipes, and the pipe group is provided with a flowmeter. The invention is characterized by reducing volatilization of organic gas, saving energy consumption for ventilation and emission reduction, enhancing accuracy ofmaterial blending, reducing manual cost, and improving working efficiency of grinding.

Description

technical field [0001] The invention relates to a grinding device, in particular to an automatic environment-friendly feeding system for a three-roller grinding machine. Background technique [0002] The three-roll mill is mainly used for various paints, inks, pigments and other slurries, especially for grinding and dispersing products with high viscosity and fine particle size. The three-roll grinding machine achieves the grinding effect through mutual extrusion of the surfaces of three horizontal rollers and friction at different speeds. A three-roll mill has three rollers mounted on an iron frame centered on a straight line. Can be installed horizontally, or slightly inclined. The steel roller can be hollow and cooled by water. The material is fed between the middle roll and the rear roll. Since the rotation directions of the three rollers are different, the rotation speed increases sequentially from the back to the front, and the distance between the rollers is adjus...

AI Technical Summary

Problems solved by technology

[0007] The feeding of the three-roll mill requires the operator to lift the slurry that has just been ground last time to the feeding opening of the three-roll mill, and pour it into the three-roll mill for the next grinding, and the cycle goes on like this In order to ensure that the slurry is successfully ground according to the factory standard, the labor intensity of the operator is high, the waiting time for the slurry to be lifted is long, the work efficiency of the grinding is low, and the labor cost of the grinding is high
