Energy-saving and environment-friendly hydraulic pulper

Abstract

The invention relates to the technical field of hydraulic repulping, and discloses an energy-saving and environment-friendly hydraulic pulper, which comprises a tank body, a sieve plate is movably installed on the lower middle portion of the tank body, a spiral rotor is movably installed in the center of the tank body, and a pulp discharging opening is fixedly communicated with one side of the tank body. Slurry is ground to generate centrifugal vortex rotation through rotation of the spiral rotor, the inclined rod cutters slide towards the outer side under the action of centrifugal force, the horizontal rod cutters and the blades longitudinally and transversely cut and grind the slurry rotating on the outer side, and the slurry on the outer side is guided to the central spiral rotor through the curved surfaces of the cutters; slurry moves from top to bottom under the action of the spiral rotor, is thrown to the inner wall of the tank body from the bottom of the rotor and then is brought to the spiral rotor again by the curved surface of the cutter to form a strong vortex, so that the impact frequency of the slurry on the spiral rotor is increased; the problem that energy is wasted due to the fact that slurry does centrifugal vortex rotating motion only under the action of a spiral rotor and needs to be ground for a long time is solved.

Description

technical field [0001] The invention relates to the technical field of hydraulic pulping, in particular to an energy-saving and environment-friendly hydraulic pulping machine. Background technique [0002] Energy saving and environmental protection hydraulic pulper is a kind of equipment that grinds pulp boards and waste book cartons into slurry by mechanical means. It is generally composed of tank body, rotor, transmission part, pulp output disc, bracket and other parts. Old books are placed in the trough, and the rotor drives the helical blades to rotate to impact and rub the pulp, and finally decompose to obtain fine pulp and discharge. [0003] There are still some problems in the existing energy-saving and environment-friendly water conservancy pulper: First, the space occupied by the rotor is small, and the rotation drives the slurry to do a centrifugal vortex motion, and most of the slurry is close to the inner wall of the tank and cannot return to the center. The gr...

Problems solved by technology

[0004] Aiming at the deficiencies in the use of the existing hydraulic pulper proposed in the background technology, the present invention provides an energy-saving and environment-friendly hydraulic pulper, which is capable of returning the slurry subjected to centrifugal force to the spiral blade for grinding, cleaning and grinding. The advantage of the impurity that produces, solved the technical problem that raises in above-mentioned background technology
