INSTALACAO PARA PREPARACAO DE PAPEL VELHO

摘要

A system for wastepaper processing which uses a newly developed wash filter of a simple design. The wash filter includes a generally round agitating space and an accepted stock space. The accepted stock space is separated from the agitating space by an essentially flat screen. An agitating wheel is positioned within the agitating space and in front of the flat screen. An entrance space for receipt of fibrous suspension and wash water is also included in the wash filter. The entrance space has a smaller diameter than the diameter of the agitating space. Flow of the suspension from either a primary pulper or a secondary pulper is received in the entrance space of the wash filter. A tailing removal line is in communication with and extends from the agitating space of the wash filter.
