A high-consistency hydraulic pulper with a sieve plate

Abstract

The invention discloses a high-concentration hydraulic pulper with a sieve plate, which includes a tank body and a rotor arranged in the tank body, the rotor is connected with a transmission device, a sieve plate is arranged under the rotor, and a fine pulp chamber is formed under the sieve plate. The fine pulp chamber is provided with a pulp outlet; the tank body is mainly composed of a cylinder and a lower head coaxially connected at the lower end of the cylinder; the lower head is a smooth and excessive spherical structure, and the inner wall of the lower head is arranged around the sieve plate in the circumferential direction. The deflector plate diffuses outward; the rotor is a helical rotor, which is mainly composed of a mandrel, a helical blade set on the mandrel and a rotor chassis set at the bottom of the mandrel. The mandrel includes a lower cone mandrel and an upper mandrel The straight section mandrel, the small diameter end of the upper end of the cone section mandrel is coaxially docked with the straight section mandrel and fixed. The invention can quickly disintegrate waste paper under high-concentration conditions, and keep the slurry properties of waste paper as far as possible, and the treatment slurry concentration can reach 10% ~ 15%, which greatly improves work efficiency and realizes energy saving and consumption reduction.

Description

technical field [0001] The invention belongs to the technical field of papermaking equipment, and in particular relates to a high-consistency hydraulic pulper with a screen plate. Background technique [0002] The traditional high-consistency hydraulic pulper is mainly used for high-concentration disintegration of waste paper and ink separation in the deinking process, and the concentration of the treated slurry can reach 10% ~ 15%. It is mainly composed of groove body, rotor and transmission mechanism. When working, the materials that need to be disintegrated when entering the cylinder, under the continuous impact, collision, friction and decomposition of the rotating helical rotor, can achieve gentle beating in a high-concentration state, and effectively mix the liquid medicine. The rubbing action sufficiently separates the ink particles from the fiber surface. The decomposed pulp with higher whiteness is discharged from the pulp outlet and enters the next process. [...

AI Technical Summary

Problems solved by technology

[0012] Although the technical solution is provided with a good pulp cavity, the good pulp cavity and the shredder cavity are fixed through a number of fixed propeller-shaped blades uniformly distributed in the circumferential direction with the rotor axis as the center line, and the direction of rotation of the propeller-shaped blades is consistent with that of the shredder. It is realized by the scheme that the screw blades of the pulper rotor rotate in the same direction, and the screening effect is poor in actual use
