Hydraulic system for controlling resin pickup
Abstract
Abstract THIS INVENTION DISCLOSES A HYDRAULIC SYSTEM FOR RESIN PICKUP THAT WILL YIELD PRECISE CONTROL OF LIQUID ADDITION WITHOUT THE NEED FOR SAMPLING, TESTING AND OPERATOR CONTROL. THE SYSTEM IS BASED ON PRECISE INTRODUCTION OF A VOLUME OF LIQUID INTO THE SYSTEM AT A VOLUME RATE OF FLOW PREDETERMINED TO YIELD A DESIRED SOLIDS CONTENT AT THE SHEET THROUGH-PUT RATE INVOLVED. THE SYSTEM IS SELF-CONTROLLING, AS A TEMPORARY DECREASE IN LIQUID ABSORPTION CAUSES AN INCREASE IN LIQUID LEVEL THEREBY INCREASING SHEET-LIQUID CONTACT TIME AND PRESSURE. CONVERSELY, AN INCREASE IN ADSORPTION CAUSES THE LEVEL TO FALL, REDUCING CONTACT TIME AND PRESSURE AND THEREBY THE VOLUME OF LIQUID ABSORBED. AN EQUILIBRIUM LIQUID LEVEL IS REACHED AT THE POINT WHERE THE ABSORPTION IS EQUAL TO THE RATE OF LIQUID IN-PUT TO THE SYSTEM.
