Abstract

The invention relates to the technical field of pulping equipment, in particular to pulping equipment for black paperboard production. A foam collecting chamber is arranged between a second partition plate and a shell, a foam cleaning mechanism is fixedly connected to the shell and extends into a stirring chamber, and foam at the upper end of pulp is pushed into the foam collecting chamber after the foam cleaning mechanism is started; a through hole is formed in the first partition plate, the rotating plate is rotatably connected to the through hole, the electric telescopic rod is fixedly connected to the shell, and the telescopic end of the electric telescopic rod is rotatably connected to the bottom end of the rotating plate. The invention further provides a pulping method of the pulping equipment for black paperboard production. The heating mechanism and the foam cleaning mechanism are controlled to be started through the stirring mechanism, slurry in the stirring chamber is heated after the heating mechanism is started, foam on the surface of the slurry is pushed into the foam collecting chamber after the foam cleaning mechanism is started, the foam in the slurry is effectively taken out, and the quality of paper is improved.

Description

technical field [0001] The invention relates to the technical field of pulping equipment, in particular to pulping equipment and a pulping method for black cardboard production. Background technique [0002] Black cardboard paper is fine, penetrating black, firm and thick, thick paper with a large weight, and has a wide range of applications. Therefore, black cardboard paper is produced in large quantities. In the production process of black cardboard Paper pollution, usually using discarded black cardboard to be crushed and re-produced. During production, it is necessary to prepare paper slurry. During the preparation of paper slurry, a layer of foam will be formed on the surface of the paper slurry during the continuous stirring process. The existing The pulp production equipment cannot remove the foam on the surface of the pulp during the production process, resulting in poor quality paper after molding. Contents of the invention [0003] The purpose of the present inv...
