Cooling water circulation device

Abstract

The invention discloses a cooling water circulation device which comprises a reaction kettle, a water pump and a water container, wherein the reaction kettle is of a dual-layer structure, a hollow interlayer is arranged between the inner layer and the outer layer of the reaction kettle, a cooling water inlet is arranged at the lower end of the reaction kettle, a cooling water outlet is arranged at the upper end of the reaction kettle, both the cooling water inlet and the cooling water outlet are communicated with the hollow interlayer, one end of a water inlet pipe is connected with a water outlet of the water container, and the other end of the water inlet pipe is connected to the cooling water inlet of the reaction kettle through the water pump, and the cooling water outlet is connected to the water container again through a water outlet pipe. According to the invention, the reaction kettle is arranged as a hollow interlayer structure and the reaction kettle is connected with the water container through the water pump and a pipeline to conduct water circulation, so that the reaction kettle is effectively cooled, and the dangers resulting from excess temperature in stirring of printing ink is avoided.

Description

technical field [0001] The invention relates to ink production equipment, in particular to a cooling water circulation device for a reactor. 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 types of cylinders...

AI Technical Summary

Problems solved by technology

However, when the basket sand mill is pre-dispersed, the sand mill head will generate heat when it rotates at high speed, and the heat will be transferred to the ink. If the temperature of the ink is too high, it will cause great danger.
