Description

Technical Field

[0001] The utility model relates to the technical field of mixed fillers, in particular to a mixed filler device for degrading paper pulp adhesives. Background Art

[0002] At present, waste paper, as an important source of secondary fiber, can not only effectively alleviate the contradiction between the shortage of papermaking fiber raw materials and energy shortage, but also help to alleviate the increasingly serious environmental pollution problem. However, in the process of waste paper recycling, various adhesives, coating adhesives, ink binders and other impurities introduced during paper production, processing and use will be released into the pulp water system in large quantities, forming stickies, which have a serious impact on the normal operation of the paper machine. The stickies biodegradation technology studied in this project uses the decomposition and oxidation reactions of biological enzymes and stickies to degrade stickies and colloidal garbage of different compositions in the system, so that they are stably dispersed in water and effectively removed.

[0003] Adding adhesive control enzymes to the slurry can effectively hydrolyze adhesives into water-soluble low-molecular substances, and can wrap and emulsify fine particle adhesives and hydrolyzed substances, so that the micro-particle adhesives are stable in the system and do not aggregate into large particles, so they are adsorbed on the fibers and taken out of the system. By utilizing the specificity of biological enzymes, the ester bonds that play an adhesive role in the sediments in the paper machine system are decomposed, the viscosity of the sediments is reduced, the sediments are passivated, and their deposition, adhesion and re-aggregation properties are reduced, and the sediments are effectively inhibited from forming deposits on the surfaces of various systems of the paper machine. The two biological enzymes are pumped to the mixing tank by an electromagnetic pulse metering pump and mixed in a certain proportion. After mixing evenly, they are pumped to the inlet of the pulp pump by a variable frequency metering pump, and the biological enzymes and the slurry are fully mixed and evenly mixed by the stirring of the pulp pump impeller.

[0004] In the prior art, when pulp stickies are degraded, a mixture needs to be added through a filling hopper, but the particles of the mixture are large, resulting in a slow degradation rate and reduced work efficiency. Utility Model Content
