A Secondary Slurry Suction Compensation Technology Method for Eliminating Surface Defects of Pulp Molded Products

Abstract

The invention relates to the technical field of pulp molded products, and discloses a secondary slurry suction compensation technology method for eliminating surface defects of pulp molded products, which solves the problem of rising and turning of slurry in the primary suction of the current suction filter device, unsaturated slurry, and Under the influence of factors, it is in the form of dripping water, which leads to the problem of product surface defects when hot-pressed, dried and fixed. It includes the following steps: Step 1, the position is raised after the initial liquid absorption; the present invention can solve the unsaturated problem of slurry suction by secondary suction. Trouble, rise to the original position after the first slurry suction and wait for 2S to 5S, so that the unsaturated slurry in the suction filter device flows out, and the saturated slurry continues to stay in the suction filter device, effectively avoiding the slurry on the surface of the suction filter device Loss and splashing; after the second slurry suction, it turns and rises to reduce the impact of gravity on the slurry in the suction filter device, to ensure the quality of the wet embryo when it is formed, thereby reducing product surface quality defects.

Description

technical field [0001] The invention relates to the technical field of pulp molded products, in particular to a secondary slurry suction compensation method for eliminating surface defects of pulp molded products. Background technique [0002] Pulp raw materials or plant fibers are pulped, crushed and mixed to form a slurry, which is transported to the forming machine through a pipeline, and firstly passed through a suction filter extrusion in the suction filter forming device to make a wet billet of the product, and the wet billet is sent alternately Into the hot pressing mold of the upper hot pressing setting device and the lower hot pressing setting device, which are located on the upper and lower sides of the suction filter forming device and heated to a certain temperature, the hot pressing mold of the upper hot pressing setting device or the lower hot pressing setting device Clamp the molds and dehydrate and dry the wet base by hot pressing to make pulp or plant fiber ...

AI Technical Summary

Problems solved by technology

[0005] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a secondary slurry suction compensation method for eliminating the surface defects of pulp molded products, which effectively solves the problem of the current suction and filtration device's primary slurry suction rising and turning, and the slurry is not saturated. , and under the influence of gravity, it is dripping water, which leads to the problem of product surface defects when it is dried and fixed by hot pressing
