METHOD FOR LEVELING PULP ADMITTED ONTO PAPERMAKING MACHINE SCREEN

摘要

pulp-and-paper industry. SUBSTANCE: method involves distributing pulp over width of pressure box in collector pipe section; separating portion of pulp and providing flow of pulp over partition wall of air chamber; turbulizing pulp in turbulence section and regulating pulp admittance rate by deforming plank in admittance opening; dividing separated portion of pulp into number of local streams over the width of pressure box; providing flow of each stream over separate partition wall and regulating flow rate of local streams by moving respective partition walls. Pulp mass between collector pipe and turbulence sections may be divided into row of longitudinal flows over width of pressure box. Method allows paper web quality to be increased by improved pulp leveling. EFFECT: simplified method and increased efficiency. 2 cl, 6 dwg, 1 tbl
