Abstract

The invention provides an automatic pressure-regulating type pressure screen. The pressure screen mainly comprises a screening and slurry storage device including a barrel body, a barrel lid and a screen cylinder, a power driving device including a motor and a spindle, an auxiliary crushing device taking an impeller rotor as a main component, an automatic pressure adjusting device including a lower cover plate, an upper cover plate, a screen rotor, rotor wings, cylinder barrels, cylinder lids, pistons, piston rods and springs as well as a guide distribution device including a guide cover and guide plates. The pressure screen is characterized by automatic radial adjustment of the screen rotor, vortex assisted filtration and secondary assisted pulping. Screening, filtration and storage of good pulp are realized through the screening and slurry storage device, the power driving device provides screening power for the pressure screen, the auxiliary crushing device realizes secondary auxiliary crushing of slurry, the automatic pressure adjusting device realizes automatic pressure adjustment and rapid vortex assisted screening of the pressure screen, and the guide distribution device realizes rapid guide and preliminary assisted crushing of fed materials.

Description

technical field [0001] The invention relates to an automatic pressure regulating pressure screen, in particular to a screening, filtering and storage of good pulp through a screening and storage device, providing screening power for the pressure screen through a power drive device, and realizing secondary crushing of the slurry through an auxiliary crushing device. Secondary auxiliary crushing, the automatic pressure adjustment of the pressure screen and the rapid vortex auxiliary screening are realized through the automatic pressure regulating device, and the rapid diversion of the feed and the primary auxiliary crushing are realized through the guiding and diverting device, which belongs to the technical research and development field of the pressure screen. Background technique [0002] As one of the most commonly used equipment in the pulp and paper industry, the pressure screen mainly generates pressure on the slurry on the surface of the screen drum through the rotation...
