Regulating pulp concentration in paper manufacturing
Abstract
Abstract THE REGULATION OF PULP CONCENTATION IN THE MANUFACTURE OF PAPER. A CARRIER LIQUID IS CONTINUOUSLY RECIRCULATED AND CARRIES THE PULP FROM WHICH THE PAPER IS MANUFACTURED. A REPLENISHING LIQUID IS ADDED TO THE CARRIER LIQUID FOR REPLENISHING THE PULP THEREOF. A COMPARISON IS MADE BETWEEN THE CARRIER LIQUID BEFORE THE REPLENISHING LIQUID IS ADDED THERETO AND THE CARRIER LIQUID AFTER THE REPLENISHING LIQUID IS ADDED THERETO. BY WAY OF THIS COMPARISON, A DETECTING ASSEMBLY DETECTS THE DEVIATION, IF ANY, OF THE RELATIONSHIP BETWEEN THE CARRIER LIQUID WITHOUT REPLENISHING LIQUID AND THE CARRIER LIQUID WITH REPLENISHING LIQUID ADDED THERETO FROM A PREDETERMINED RELATIONSHIP THEREBETWEEN. IN ACCORDANCE WITH THE DETECTED DEVIATION, IF ANY, AN ELECTRICAL SIGNAL IS ACHIEVED FOR ELECTRICALLY ADJUSTING A VALVE WHICH CONTROLS THE SUPPLY OF REPLENISHING LIQUID TO THE CARRIER LIQUID, AND IN THIS WAY THE SUPPLY OF REPLENISHING LIQUID TO CARRIER LIQUID IS MAINTAINED AT AN EXTENT WHICH WILL MAINTAIN THE PREDETERMINED RELATIONSHIP BETWEEN THE CARRIER LIQUID WITHOUT REPLENISHING LIQUID AND THE CARRIER LIQUID WITH REPLENISHING LIQUID ADDED THERETO.
