Abstract

The invention provides pulping equipment based on air blasting energy and with a secondary repulping function. The pulping equipment mainly comprises a coarse pulp generating device, a bubble generating device, a bubble heating device and a fine pulp generating device. The pulping equipment is characterized in that air blasting energy is used for repulping and secondary fine repulping. Repulping through the air blasting energy is achieved through the bubble generating device and the bubble heating device; multi-area blasting repulping is achieved through upper and lower exhaust rings; scallop tubes are used for guiding bubble diversion, so that the upper and lower exhaust rings are protected; Y-shaped filters are used for screening and filtering crushed materials; the coarse pulp generating device is used for generating coarse pulp; and the fine pulp generating device is used for achieving fine repulping.

Description

Technical field [0001] The invention relates to a pulping equipment based on air blasting energy and secondary pulping, in particular to an air blasting energy pulping realized by a bubble generating device and a bubble heating device, and multi-zone blasting crushing is realized through upper and lower exhaust rings The pulp is guided by the fan-shaped pipe to divide the air bubbles to protect the upper and lower exhaust rings; the Y-shaped filter is used to screen and filter the scraps, the coarse slurry generator is used to generate coarse slurry, and the fine slurry generator is used to achieve fine pulping , Belongs to the technical research and development field of pulping equipment. Background technique [0002] As one of the most commonly used pulping equipment in the pulp and paper industry, hydraulic pulpers mainly break pulp boards, waste books, waste cartons, etc. However, due to the unity of the working mode and structure of the current pulper, the following problem...
