Abstract

The invention discloses a flotation deinking machine, it includes deinking machine shell, liquid feeding mouth installed on one side of deinking machine shell and liquid discharging mouth installed on another side of deinking machine shell, ink-gathering device installed in the upper of the cavity of deinking machine shell and the slag hole connected with the ink-gathering device, the bottom of said cavity of deinking machine shell is equipped with several micropore aeration device which can transmit flotation foam to the liquid in deinking machine shell, and air intake pipes connected with micropore aeration device, said several micropore aeration device is equipped with foam-generating hole which can generate foams in different diameter; due to the distribution of the diameter and the amount of flotation foam are matched with the size and the amount of the ink particles contained in the flotation pulp, ink particles in different diameters can be bright away by the flotation foam, the deinking is more thorough and the pulp quality is higher.

Description

Technical field

[0001] The invention relates to a papermaking machine, in particular to a machine designed for deinking waste paper pulp or papermaking wastewater. Background technique

[0002] In the waste paper processing technology, the recovered waste paper is crushed, decomposed, and added with medicine to separate the printing ink from the fiber in the waste paper to form an undeinked pulp suspension, that is, mortar. Then the flotation process is used to deink the waste paper pulp to improve the whiteness of the waste paper pulp. As we all know, air bubbles play an irreplaceable role in flotation. The number, size and stability of bubbles all affect the flotation effect. The ratio between the size of the air bubble diameter and the size of the ink particles is an extremely important factor affecting the flotation effect. Large ink particles need large bubbles to adsorb it, and small ink particles need small bubbles to adsorb; after testing, The ratio of the air bubble diam...
