MEASURING DEVICE FOR NATURE OF MUDDY WATER AND CYCLONE DEVICE CONTROL SYSTEM FOR USE IN MUDDY WATER CONSTRUCTION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a muddy water nature measuring device for measuring in real time and with accuracy under muddy water obtained when the muddy water to be treated is classified by a cyclone device and to provide a cyclone device control system for controlling the classification of the cyclone device. ;SOLUTION: An iron core 410 is moved back and forth by the displacement of a recessed face part 310 and an induced voltage is generated by an induced voltage generating part 420 through the moving back and forth of the iron core 410. Using a measuring device 430, a force applied to the recessed face part 310 by under muddy water is measured on the basis of the value of the induced voltage, and the nature of the under muddy water is determined on the basis of the force. The aperture opening of the apex valve of a cyclone device is controlled on the basis of the nature to adjust the classification of the cyclone device.;COPYRIGHT: (C)2000,JPO
