Abstract

The invention provides a rotorless pulping equipment based on a three-layer air vortex as stirring power, which mainly includes a three-layer air vortex generating device and a liquid slurry generating device. Its characteristic is that the air flow vortex generator produces upper, middle and lower three-layer vortex, and uses the vortex kinetic energy to crush the material and mix it with liquid water to form a slurry. In the present invention, the inner diameters of the upper-layer airflow delivery pipe, the middle-layer airflow delivery pipe and the lower-layer airflow delivery pipe are halved successively to realize the pressurization and speed-up of the airflow; through the symmetrical and anisotropic arrangement of the upper-layer airflow outlet, the middle-layer airflow outlet and the lower-layer airflow outlet, three Formation of laminar airflow vortex; the staggered and uniform arrangement of upper airflow vortex generation tubes, middle layer airflow vortex generation tubes and lower layer airflow vortex generation tubes prevents large airflow period pulsation.

Description

technical field [0001] The invention relates to a rotorless pulping device based on three-layer airflow vortex as stirring power, in particular to a method for realizing the pressurization of airflow by successively halving the inner diameters of the upper-layer airflow conveying pipe, the middle-layer airflow conveying pipe and the lower-layer airflow conveying pipe To increase the speed, the three-layer airflow vortex can be generated through the symmetrical and anisotropic arrangement of the upper airflow outlet, the middle airflow outlet and the lower airflow outlet. The staggered and uniform arrangement prevents the periodic pulsation of large air flow, and belongs to the technical research and development field of pulping equipment in the paper industry. Background technique [0002] In the papermaking industry, pulp generation requires putting pulp boards, waste books, waste cartons, etc. into a hydraulic pulper, and disintegrating them through the rotation of the rot...
