A mica pulp separation box used in mica paper production process

Abstract

The invention discloses a mica pulp dividing box used in the mica paper production process. The mica pulp dividing box is characterized in that the interior of a box body is divided into a pulp mixing cavity, a pulp precipitation cavity and a splitter cavity by a first partition plate and a second partition plate; a pulp inlet pipe is arranged above the pulp mixing cavity; a lower splitter opening is formed at the lower part of the first partition plate to communicate the pulp mixing cavity with the pulp precipitation cavity; an upper splitter opening is formed at the upper part of the second partition plate to communicate the pulp precipitation cavity with the splitter cavity; a plurality of pulp outlet pipes are connected at the bottom of the splitter cavity; a main water pipe is arranged at the side of the pulp mixing cavity and extends to the bottom of the pulp mixing cavity via a spray pipe communicated with the main water pipe; blowholes are formed in the side wall of the spray pipe. The mica pulp dividing box used in the mica paper production process has small volume, mixes pulp uniformly and quickly, can meet the requirements of higher concentration pulp, ensure discharged pulp concentration uniformity and flow velocity stability and prevent layering and precipitation of the pulp and is beneficial to improving the mica paper grade and the production quality.

Description

technical field [0001] The invention belongs to the field of mica processing and production, in particular to a mica pulp separation box used in the mica paper production process. Background technique [0002] Mica paper is a kind of high-quality insulating material, which has the characteristics of non-toxic, odorless, high temperature resistance, high pressure resistance, aging resistance, corrosion resistance and high dielectric strength, especially its high temperature resistance and reworkability are irreplaceable by other materials . The preparation method is generally to mix mica materials, use chemical or mechanical methods to pulp and make paper, and then cut and rewind into continuous roll paper. Mica paper not only maintains the characteristics of natural mica sheet, but also has low production cost and small thickness tolerance, so it is the replacement product of expensive natural mica sheet. [0003] Mica paper is a paper-like non-metallic mineral material. I...

Problems solved by technology

This kind of separation box takes up space and is too large, which is not conducive to cleaning and maintenance

The second is that the flow velocity of the slurry outlet of the lower box is all derived from the drop potential energy of the upper water tank, resulting in too small flow velocity. Once the slurry concentration is too high due to production requirements, the slurry cannot be dispersed evenly or even sinks, which seriously affects production efficiency. , reducing the quality of production

The third is that the mica slurry is prone to laminar flow due to the fixed flow velocity and flow direction during the mixing process. The mica slurry will be unevenly mixed and the slurry will be stratified during the mixing process, even if the flow rate meets the requirements and the slurry meets the requirements. , there will be stratification of the slurry, and the aging of the mica slurry will greatly affect the production and reduce the production quality
