Environment-friendly granulation unit specially used for papermaking

Abstract

The invention provides an environment-friendly granulation unit specially used for papermaking and specifically relates to the technical field of production equipment for materials. The left side of a pressurized banbury mixer (1) is provided with a material bucket elevator (2); the left side of the material bucket elevator (2) is provided with a taper twin-screw feeding machine (3) and a single-screw extruder (4); the left end of the single-screw extruder (4) is provided with a hydraulic plate-type automatic screen exchanger (5); the left end of the hydraulic plate-type automatic screen exchanger (5) is provided with an air-cooled mold surface hot cutting head (6); and the left side of the air-cooled mold surface hot cutting head (6) is provided with a primary cyclone separator (7), a secondary cyclone separator (8) and a ternary cyclone separator (9). The granulation unit can produce stone paper master batch meeting requirements in one shot, has high output and small labor intensity, saves energy, enables the environment of a production workshop to be improved and produces no environmental pollution.

Description

Technical field: [0001] The invention relates to the technical field of material production equipment, in particular to a special granulation unit for environmental protection papermaking. Background technique: [0002] Rich Mineral Paper, abbreviated as RMP, means "mineral-rich paper", which is made by grinding stone (mainly calcite with high CaCO3 content) into a fine powder with a fineness of 8-125 mesh, and then adding about 8% The stone powder is added with 15% polyethylene and 5% adhesive, after compatible mixing, granulation, film forming, coating and other processes, using the principle of polymer interface chemistry and filling modification technology, blow molding to produce a A new paper that is recyclable, has modern technical features, and functions similar to traditional structural fiber paper. [0003] The existing stone paper masterbatch unit needs to go through the double-stage extruder unit twice in a row and carry out two processes. It first feeds the mat...
