Abstract

The invention provides pulping equipment based on a high-pressure water jet and combined type rotor pulping. The equipment mainly comprises a high-pressure water conveying device, a water jet pulping device, a combined rotor pulping device and a pulp generating device. The pulping equipment based on the high-pressure water jet and combined type rotor pulping is characterized in that preliminary pulping of the high-pressure water jet replaces a feed cylinder to inject water, and a mobile smashing knife in the combined rotor pulping device freely adjusts the height and assists in smashing feed. According to the pulping equipment based on the high-pressure water jet and combined type rotor pulping, a pulping blind area at the bottom of the feed cylinder and a 'rotary cake' phenomenon are eliminated through a triangular smashing knife, freely combined non-blind-area and efficient secondary pulp is achieved through the combined rotor pulping device, fast engagement and separation of the rotor and the mobile smashing knife are achieved through special structural teeth, and pulping efficiency is improved and uniform feed smashing is achieved through high-pressure exhaust pipes and conical holes which are distributed circumferentially evenly and in a dispersed mode of an arithmetic progression.

Description

technical field [0001] The invention relates to a pulping equipment based on high-pressure water jet and combined rotor pulping, in particular to a kind of pulping blind area and "rotary cake" phenomenon at the bottom of the material cylinder which are eliminated by a triangular crushing knife, and which are crushed by a water jet pulping device. The water injection of the barrel is converted into the primary pulping of the high-pressure water jet, and the free combination of high-efficiency secondary pulping without blind spots is realized through the combined rotor pulping device. The high-pressure nozzles and conical holes, which are uniformly distributed in the circumferential direction and distributed in equal numbers, improve the pulping efficiency and homogenize the crushed materials, which belong to the technical research and development field of the pulping equipment. Background technique [0002] As one of the most commonly used pulping equipment in the pulp and pa...
