<p>PURPOSE:To intend improvement of extraction property and reliability by providing a compressed air jet nozzle, an exhaust nozzle and another compressed air jet nozzle relatively movable to each nozzle. CONSTITUTION:While a compressed air jet nozzle 10 at a movable side is made to move rotatively toward another compressed air jet nozzle 11 at a stationary side, compressed air from a compressed air supplying device 1 is supplied to a route, an inside of main body 13b of pulsator at the movable side, to, the nozzle 10 at the movable side, to, the nozzle 11, to, a pulse leg 5, in order to descend liquid surface of the leg 5 and ascend liquid surface of column 7, as well. After the procedure is completed, the main body 13b is rotated and the nozzle 10 is made to move rotatively toward the nozzle 11. On the other hand, the compressed air from the device 1 is discharged to an atmosphere via the main body nozzle 10 and then the nozzle 9, in order to raise liquid surface of the leg 5 and lower liquid surface of the column 7, as well. In this occasion, the liquid moves by liquid surface difference and vacuum pressure and therefore moving velocity of the liquid surface becomes high.</p> |
