Abstract
The utility model relates to a concentrated pond coal slime water concentration detection device. Tradition gradiomanometer adopts throttling arrangement adjustment compressed gas flow, requires to insert the even bubbling of trachea in the concentrated pond, because the compressed gas flow of throttling arrangement adjustment is unknown, and the gas flow of throttling arrangement output is inhomogeneous, and the bubble is not controlled well in coal slime aquatic bubbling speed. In this patent the air supply behind the clarifier respectively through sweep the device flowmeter to the same gas flow of two way gas circuit output to the trachea in, because two tracheas are different at coal slime aquatic depth of inter fit, can go into tubular one -tenth pressure differential in two thongs, differential pressure transmitter's differential pressure detection device connects two way gas circuit respectively, two insert tube pressure differential sizes of real -time detection show, the transmission, calculate out coal slime density of water through the differential gauge, according to the relation between coal slime watertight degree and the concentration, thereby the coal slime that converts out water concentration. The device is reliable and stable, can realize dynamic real -time detection to in transmitting the testing result to PLC ( programmable controller ) dispatch control ware or host computer with analog quantity or serial communication mode.
