AI Technical Summary

Technical Problem

Existing water-closed-loop waste paper pulping facilities are prone to generating a large amount of foam and air bubbles during the pulping process, leading to production instability and a decline in the quality of finished pulp, which cannot meet the demand for high-quality and stable closed-loop pulping.

Method used

The drive components work together to automatically seal the cover plate, forming a closed space. Combined with the piston plate sliding to compress the volume of the chamber, a dual foam suppression structure of "sealed air isolation + pressurization and defoaming" is formed, which prevents external air from being drawn in and crushes residual bubbles.

Benefits of technology

It effectively stabilizes the liquid level and turbulence state within the cavity, improves pulping quality and efficiency, reduces reagent consumption and maintenance costs, has a wider range of applications, is more economical, and is suitable for continuous industrial production.

Abstract

The application discloses a water-sealed circulating waste paper pulping mechanism and relates to the technical field of pulping.The water-sealed circulating waste paper pulping mechanism comprises a feeding and pulping component, a deinking and screening component and a white water recovery component.During the water pulping operation, through the cooperation of a driving assembly, a sealing assembly, a pushing assembly and a pressurizing assembly, the driving structure linkage realizes accurate sealing of the cover plate, the water pulping machine body forms a sealed environment, the outside air is blocked from being mixed into the pulp body with the stirring turbulence from the source, the basic condition for preventing a large number of bubbles from being generated is achieved, meanwhile, the transmission forms a micro-pressurized environment in the cavity, the residual fine bubbles can be squeezed and broken, the double bubble suppressing and defoaming effects are realized, the problems that the foam occupies the effective volume of the cavity, the fiber pulping is not complete and the dissociation is uneven are effectively avoided, and the pulping operation efficiency and uniformity are greatly improved.
