A Widened Pulp Tank Structure for Broken Paper Pulper

Abstract

The invention discloses a widened pulp tank structure for a broken paper pulper, comprising a pulp tank in which a rotor is arranged, and the pulp tank is surrounded by a front side wall, a rear side wall, left and right side walls and a tank bottom The upper open structure formed by combining; wherein, the front side wall is in the shape of a circular arc, the top of which is connected to the feeding slide, and the bottom is smoothly connected with the bottom of the pool; the top of the rear side wall is tangent to it and connected with a whirling arc; The bottom of the pool is guided downward by the rear side wall to the front side wall; a diversion cone is arranged at the lateral middle position of the rear side wall, and two rotors are symmetrically arranged on both sides of the diversion cone, and the rotation direction of the two rotors is opposite. The back of the rotor is provided with a slurry outlet. In the vertical section, the present invention increases the strength of the interaction between broken paper in the pulp tank, and on the other hand increases the contact frequency between it and the rotor; at the same time, in the horizontal section, two sets of symmetrical double vortex flow form three Vortex channels, the paper interaction between the vortex channels is extremely strong, which can speed up the breaking of damaged paper to the greatest extent.

Description

technical field [0001] The invention relates to the technical field of papermaking equipment, in particular to a device for disintegrating broken paper in a part of a paper machine. Background technique [0002] During the papermaking process, a large amount of broke, ie unformed or defective paper, is produced in the paper machine section. These brokes are free of impurities and can be reused after shredding. Broken paper is often disintegrated by setting a broken paper pulper under the paper machine. Due to the limited space, most broken paper pulpers adopt a horizontal structure, that is, the pulper rotor and the horizontal plane are perpendicular to each other. [0003] This kind of broke pulper requires a pulp pit under the paper machine for pulping, and the traditional broke pulp pit has a flat cubic structure, which is easy to manufacture. This kind of pulp pool has a low height and a width close to the width of the paper machine. When the pulper rotor is working, t...

Problems solved by technology

[0007] However, the above-mentioned technical scheme still utilizes the disintegration effect of the rotor of the pulper to work, and does not make good use of the interaction between laminar flow and turbulent flow in the pulp flow, and the disintegration efficiency of broken paper is low, the time is long, and the energy consumption is large.
