Embodiment

[0023] Such as figure 1 , figure 2 As shown, a high-pressure air-jet swirling-type vortex kinetic energy pulping equipment of the present invention mainly includes a slurry-slurry generating device, a high-pressure air supply device and a high-pressure air-jet swirling device. The high-pressure air supply device is mainly composed of an air compressor 2 and an air delivery pipe 16. The air compressor 2 is installed below the pulper barrel 3. The air delivery pipe 16 is drawn out from the air compressor 2 and goes deep into the pulper barrel 3. The air delivery pipe 16 Four supporting rods 13 uniformly distributed in the circumferential direction are installed on the upper end. Slurry The slurry generating device is mainly composed of a pulper cylinder 3 and a cylinder cover 10. The cylinder cover 10 is a disc-shaped structure, and the cylinder cover 10 is symmetrically opened with an arc-shaped feed and exhaust port A7 and a feed and exhaust port. Port B12; the pulper barre...

Abstract

The invention provides high pressure air injection eddy making type eddy kinetic energy pulping equipment which mainly comprises a thick liquid generating device, a high pressure air supply device and a high pressure air injection eddy making device. The high pressure air injection eddy making type eddy kinetic energy pulping equipment is characterized in that the high pressure air injection eddy making device generates eddies inside a pulper cylinder, and an upper baffle and a lower baffle shear and beat the eddies during eddy fluid motion. Pressurizing and acceleration of gas are achieved through the dip angle design of a tilting tray. A turbulent flow block at the tail end of the tilting tray is prevented from being disengaged from fluid to generate eddies and secondary pressurizing and acceleration are achieved. Due to the dip angle design at the initial end of an air injection channel, gradual change of the air flow direction is achieved, and kinetic energy losses are reduced. Gentle direction changing, repeated pressurizing and acceleration and small kinetic energy losses can be achieved through the circular bead optimal design of the middle end and the initial end of the air injection channel. Due to the fact that triangular sawteeth are arranged and the upper and lower baffles are arranged in a staggered mode, all-directional shearing and beating of crushed aggregates are achieved, and the pulping efficiency is improved.

Description

technical field [0001] The present invention relates to a high-pressure air-jet vortex-generating vortex kinetic energy pulping equipment, in particular to a kind of pressurization and speed-up of gas through the inclination design of the swash plate; Acceleration by secondary pressurization; through the design of the inclination angle at the beginning of the jet channel, the direction of the airflow is gradually changed and the loss of kinetic energy is reduced; through the optimized design of the rounded corners at the beginning and middle of the jet channel, the smooth direction of the flow, multiple pressurization speed-up and small Kinetic energy loss; through the triangular sawtooth and staggered arrangement of the upper and lower baffles, the omni-directional shearing and disintegration of the scrap can be realized, and the pulping efficiency can be improved, which belongs to the technical research and development field of pulping equipment in the paper industry.
