A kind of dispersing equipment for paper making pulp by using reciprocating increasing and decreasing pressure dispersing

Abstract

The invention discloses a papermaking pulping dispersion device based on reciprocated pressure increase and reduction. The papermaking pulping dispersion device structurally comprises a feeding funnel, a pulping tank, a base and a pulp dispersing device. A stirring cross bar stirs paste, a spiral backflow blade delivers the paste upwardly, and the paste is thrown at the top into a holding groove under the action of a centrifugal force; an upwardly-inclined inverted triangular block is arranged at the middle end of the left wall, and the paste conveniently flows into the holding groove; when atube support slides leftwards, a seal ring is sucked on a filtering plate due to negative pressure; a fixing sucker extracts the paste from the right end of the filtering plate, a retractable ring isin an extension state, the seal ring applies compressional deformation pressure to a boosting groove at the middle end, the retractable ring has a compression effect on an air bag after extension, theseal ring and the filtering plate are separated from the inside, air leakage is achieved, an auxiliary boosting ring slides leftwards together with the paste in the fixing sucker, the suction strength of the fixing sucker on the paste is enhanced to allow the sticky paste to penetrate through holes of the filtering plate, and through air pressure suction, the physical impact is prevented to avoiddamage to the overall viscosity of the paste.

Description

technical field [0001] The invention relates to a dispersing device for pulping in papermaking by using reciprocating increasing and decreasing pressure to disperse, and belongs to the field of pulping devices in papermaking. Background technique [0002] As one of the indispensable daily necessities, paper has been widely used in various items of life. During the manufacturing process, the slurry needs to be dispersed. Most of the slurry is dispersed by extrusion and separation, and the tip of the push rod is used to cooperate with the Squeeze the slurry through the corresponding through holes, and drain the water while squeezing, and then use the receiving plate at the bottom to carry out subsequent processing on the dispersed slurry. [0003] However, the existing papermaking pulp dispersion equipment has the following disadvantages: [0004] Use the tip of the push rod to match the corresponding through hole to squeeze the slurry through, and the water will be drained a...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a papermaking pulping dispersing device that utilizes reciprocating pressure increasing and decompressing to disperse, so as to solve the problem of using the tip of the push rod to cooperate with the corresponding through hole to squeeze the slurry through and squeeze the pulp through. At the same time, the water will be drained. Due to the instantaneous extrusion of the tip, it will cause a certain degree of damage to the slurry, which will directly make the slurry more fragmented and affect the subsequent paper forming. At the same time, the fragmented slurry components will reduce the viscosity of the slurry. It is easy to attach to the through hole and the tip of the push rod, which will cause blockage to the subsequent dispersing action. It needs to be checked and cleaned in time, which will increase the working pressure and the problem of steps.
