Novel light impurity deslagging device

Abstract

The invention discloses a novel light impurity deslagging device and aims to solve the problem that in the prior art a deslagging device is incomplete in separation and poor in deslaging effect. The deslagging device comprises a deslaging tube, an accepted stock tube and a light slag collection tube, wherein the deslagging tube takes the shape of a column and is vertically arranged; a slurry inlettube which is in tangent communication with the deslagging tube is arranged at the upper end of the deslagging tube; the accepted stock tube extends into the inner cavity of the deslagging tube fromtop to bottom; an accepted stock outlet which is communicated with the accepted stock tube is arranged at the upper end of the accepted stock tube in a horizontal direction; the light slag collectiontube is positioned inside the accepted stock tube; the upper outlet of the light slag collection tube is higher than the upper end of the accepted stock tube; the lower end of the light slag collection tube also extends into the inner cavity of the deslagging tube; the deslagging tube, the accepted stock tube and the light slag collection tube are coaxially arranged; an annular area is formed between two adjacent tubes. The novel light impurity deslagging device disclosed by the invention is simple in structure and convenient to use, the difficulty that light impurities of the deslagging device are hard to separate is sufficiently solved while the deslagging efficiency of heavy impurities of the deslagging device is not changed, and the deslagging device has very good practicability.

Description

technical field [0001] The invention relates to the technical field of papermaking pulping purification treatment equipment, in particular to a novel light impurity slag removal device. Background technique [0002] Slag cleaners were used in the paper industry in the early 1920s and have been widely used since 1950. At present, in the waste paper pulping process, the slag cleaner is an indispensable part of the whole system. According to the impurities removed, the slag remover can be divided into heavy slag remover, light slag remover and multi-functional slag remover. At present, the raw materials for waste paper pulping are all recycled waste paper, which contains not only heavy impurities such as sand and dust, but also light impurities such as plastic chips, wax, foam, etc. The slag removal effect is very good, but the treatment of light impurities has always been a major problem in the domestic paper industry. The existing light slag remover is not completely separa...
