Abstract
PURPOSE:To obtain stable seed pulp concentration by calculating a flow rate from the pulp concentration in a blow tank and takeout pulp concentration which is preset in a calculator, and controlling the opening extent of a diluting water valve with a signal of the result. CONSTITUTION:In a pulp manufacturing factory, the signal 5 of the load current of the driving motor M of a stirring machine 2 is inputted to the calculator 6, the flow rate signal 8 of a flowmeter 7 fitted to a seed pulp pipe 3 is inputted to the calculator 6, and the preset seed pulp concentration is set in the calculator 6. Then the calculator 6 calculates the pulp concentration with the input signal 5 of the load current and flow rate signal 8 and calculates the flow rate of diluting water from the found pulp concentration and preset seed pulp concentration to output a signal of the diluting water flow rate; and the flow rate of a diluting water pipe 4 is calculated, and the opening extent is controlled with the signal 10 of the flow rate in the pipe 4 to supply the diluting water into the blow tank 1 from the pipe 4.
