Multi-circulation type automatic paper pulp impurity screening device and working method thereof

Abstract

The invention discloses a multi-circulation type automatic paper pulp impurity screening device and a working method, wherein a waste paperboard feeding magnetic separation conveying belt, a paper pulp stirring unit, a paper pulp transferring unit, a paper pulp impurity screening unit, a paper pulp vibration screening unit, a paper pulp forming unit and a paper pulp discharging unit are sequentially arranged according to production procedures. According to the invention, the multi-circulation type automatic paper pulp impurity screening device is reasonable in structure and design, high in automation degree, high in working efficiency and flexible in application; heavy metal impurities and other light impurities are separated and filtered through the waste paperboard feeding magnetic separation conveying belt, so that the filtering effect is improved, and metal scrap iron is removed from slurry while the slurry is conveyed through the conveying belt; and two-stage screening is formed through the paper pulp impurity screening unit and the paper pulp vibration screening unit, so that dust or large fiber impurities in the paper pulp can be completely removed.

Description

technical field [0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to a multi-cycle automatic pulp impurity screening device. The invention also relates to a working method of a multi-cycle automatic pulp impurity screening device. Background technique [0002] The main production process of pulp molded products is: first, the waste paper or carton edge is crushed into fiber pulp by a hydraulic pulper, and then the pulp is formed by adsorption with the help of a mold, and then dried and shaped to form a pulp molded product. The traditional slurry production line for pulp molding products simply puts waste paper or carton sides into the hydropulper, and after a certain period of time, the slurry is directly discharged into the pulp tank for use in subsequent processes. [0003] Pulp is a fibrous substance made from plant fibers through different processing methods. According to the processing method, it can b...
