AI Technical Summary
The existing dispensing device has a fixed dosing point, which leads to uneven contact between the agent and the pulp, creating "dead zones" with excessively high or low concentrations in some areas. This affects the bleaching effect, and solid impurities are mixed in with the pulp, reducing paper quality.
An adjustable flow bleaching agent dispensing device was designed. The dispensing depth of the agent is adjusted by a lifting pipe, gear and rack mechanism, and a filtration mechanism is equipped to filter solid impurities, ensuring uniform distribution of the agent and removal of impurities.
This achieves uniform distribution of the reagent, improves bleaching effect and reaction efficiency, reduces the probability of solid impurities appearing on paper, and improves paper quality.
