Efficient pulping system for dry and wet broken paper

Abstract

The invention discloses an efficient dry and wet broken paper pulping system which comprises a pulping cylinder and a conveyor used for feeding, the pulping cylinder comprises an upper pulping cylinder and a lower pulping cylinder, a pulping device A and a pulping device C are arranged in the upper pulping cylinder and the lower pulping cylinder respectively, a discharging pipe is arranged at the bottom of the lower pulping cylinder, and a feeding pipe is arranged at the bottom of the lower pulping cylinder. And the bottom of the upper repulping cylinder is communicated with the top of the lower repulping cylinder through the central repulping cylinder. The invention relates to the technical field of papermaking. According to the efficient repulping system for the dry and wet broken paper, the dry broken paper can be conveyed into the upper repulping cylinder through the conveyor to be repulped for the first time, then the repulped dry broken paper and wet pulp which is added later are put into the central repulping cylinder at the same time, and pulp in the shell is rapidly repulped in a narrow space through the repulping devices B which are oppositely arranged; and after passing through the shell, the pulp flows into the lower pulping cylinder for third-time pulping work. The oppositely arranged repulping device B is used for quickly grinding the pulp, so that the repulping speed is increased.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a high-efficiency pulping system for wet and dry broken paper. Background technique [0002] In the paper production process, it is divided into virgin paper and recycled paper. When recycled paper is processed, broken paper needs to be put into a pulper for processing. Broken paper is divided into dry damage and wet damage. Usually, dry damage needs to go through the defibrosis and refining process, while wet damage can directly enter the pulper. Therefore, under normal circumstances, the work needs to be carried out separately, which increases the input amount of equipment. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the invention provides a high-efficiency pulping system for dry and wet broken paper, which solves the problem that dry and wet broken paper cannot be processed at the same time. [0004] In order to achieve the above ob...
