A Fiber Dispersion Equipment for Papermaking Based on Fluid Mechanics

Abstract

The invention provides a fiber dispersion device and method for papermaking based on hydromechanics, the fiber dispersion device comprises a hollow base, a dispersion tank, a paper pulp hopper, a negative pressure dispersion mechanism and a gas shock decompression dispersion mechanism, the dispersion tank is fixedly installed on the hollow base, the surface of the paper pulp hopper is fixedly connected with the inner wall of the dispersion tank, and the negative pressure dispersion mechanism is fixedly installed on the dispersion tank. The invention relates to the papermaking field. Accordingto the fiber dispersion device and method for papermaking based on hydromechanics, water is utilized and guided. Fibers are dispersed at a high speed in a narrow space through movement of two kinds offluid, the fibers are dispersed in a continuous fluid hedging mode, and the fibers are slowly conveyed to a slow oscillation area in a damping mode through hedging residual waves, so that the problemthat when ordinary fiber dispersing equipment disperses the fibers, the dispersing step is single, stubborn fiber clusters are not prone to being scattered under the inertia effect, when equipment stops, fibers are prone to being gathered and wound again, and the dispersing efficiency is low are solved.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a fiber dispersing device for papermaking based on fluid mechanics. Background technique [0002] In the papermaking process, pulp needs to be produced. The main raw material of finished paper in Zhijiang City. The quality of pulp will also directly affect the quality of the final paper. The uniform dispersion of fibers makes the quality of paper higher. During the production process of pulp, it needs to be broken. The material is broken up into fibers. Due to the high-strength crushing during the crushing process, some fibers are easily intertwined to form some fiber clusters. These fiber clusters need to be broken up in water. At present, the main process of breaking up is to concentrate the fibers in the Together, the general stirring device is used as a breaking device to break up the fibers. Although the stirring device can play a role in breaking up to a certain extent,...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a fiber dispersing equipment for papermaking based on hydrodynamics, which solves the problem that when the general fiber dispersing equipment disperses the fibers, the dispersing steps are relatively single, and the stubborn fiber clusters are under the action of inertia. , not easy to be scattered, when the equipment stops, the fibers are prone to re-gathering and winding, and the dispersion efficiency is low
