High-efficiency processing system of medium-low viscosity printing ink

Abstract

The invention discloses a high-efficiency processing system of medium-low viscosity printing ink. The system comprises a reaction kettle, wherein the bottom of the reaction kettle is connected to a mass flow circulation sand mill through a printing ink circulation pipe and a circulation pump; the other end of the printing ink circulation pipe is located in a feeding hole at the upper part of the reaction kettle; a high-speed stirring device and a basket sand mill are arranged outside the reaction kettle to stir the printing ink successively; and the reaction kettle is further connected with a reaction kettle cooling water circulation device. The capacity of the mass flow circulation sand mill is 3-4 times more than that of a pass type sand mill. The printing ink passing through the mass flow circulation sand mill returns the reaction kettle and quickly mixed well with the printing ink in the reaction kettle to make the printing ink uniform. The system can effectively shorten sanding time for the printing ink, increases wetting time of the printing ink when sanded, reduces losses during the sanding process, is compact in technological structure, reduces cleaning procedures, improves sanding effect of half-finished products, and greatly reduces manpower and material resources for the enterprise.

Description

technical field [0001] The invention relates to ink production equipment, in particular to an efficient processing system for medium and low viscosity inks. Background technique [0002] Ink production generally includes 4 working sections: stirring pre-dispersion, sanding, tempering (color toning), filtration and packaging. How to integrate these sections into a set of equipment is a direction for the future development of ink production. The key to determining whether these processes can be connected or integrated is the sanding section. [0003] At present, there are mainly recirculation with supply channels in China, and some advanced ones also have multi-pass circulation, but these sanding methods cannot be combined with other sections. The disadvantages of the two production processes of recirculation with supply channels and multi-pass circulation are that they both use sand mills to directly sand the ink in the batching part, and need to switch between different ty...
