Abstract

The invention provides a pressure pulp screening machine which comprises a shell, wherein a screen drum and a rotary wing are arranged in the shell, the rotary wing is matched with the screen drum, the rotary wing and the screen drum move relative to each other in a circumferential manner, and a pulp inlet and a good pulp outlet are arranged on the shell; and the pressure pulp screening machine is characterized in that: a spiral dreg discharging machine is arranged on the shell close to a dreg discharging end of the screen drum along the conveying direction of light dregs in a connecting way;a dreg inlet of the spiral dreg discharging machine is connected with the shell nearby the dreg discharging end; and a dreg outlet of the spiral dreg discharging machine is communicated with the outside. When the pressure pulp screening machine in the invention is adopted, the light dregs can be removed in the form of dry dregs without stopping the pressure pulp screening machine.

Description

technical field [0001] The invention relates to the field of papermaking machinery, in particular to a modified intermittent pressure screener. Background technique [0002] Pulp pressure screen, that is, the pressure screen machine is a device for screening waste paper pulp. From its structure, the pulp pressure screen is composed of a cylindrical screen drum and a rotor located in the inner cavity of the screen drum. When the rotor When rotating, the rotor on the rotor generates a hydraulic pulse near the sieve plate, so that the good pulp containing a large amount of fibers passes through the sieve plate to obtain good pulp products suitable for papermaking, and at the same time rely on the instantaneous suction pulse generated when the rotor rotates to clean the screen drum. Purification, the separation and removal of impurities in waste paper pulp. Wherein, the above-mentioned impurities in the waste paper pulp can be divided into heavy residue and light residue accord...
