ある。Next, the final dewatering step and drying step will be explained based on the flowchart of FIG. 1. This dehydration process is
The solvent from the tank 3 is supplied to the outer tank 1 and the drum 2 by the pump 14, and the drum 2 is rotated at low speed in a batch or circulation state. This is then executed as follows.

、振動スイッチ4が作動しない時間をカウントする。In this draining process, the draining control section 26 first opens the drain valve 16 and controls the drum 2 using an inverter to rotate in one direction at 60 rpm. Next, the operation of the vibration switch 4 is checked, and if it is activated, the rotation of the drum 2 is stopped and the rotation detector 22 is activated.
Restarts when detects zero rotation. The timer 27 counts the time during which the vibration switch 4 is not activated.

トのスリップ等を原因として上がらないことがある。In this way, when the timer 28 counts the deliquing time without abnormal vibration, the delitting control section 26 stops the output and moves to the next drying process. By the time this dehydration time has elapsed,
The rotational speed of the drum 2 is checked by the rotation detector 22, and the determination section 28 compares and determines whether the measured rotational speed exceeds 500 rpm, which is sufficient to ensure a normal liquid removal rate, and outputs an output when the rotational speed exceeds 500 rpm. Then, a drying flag is set based on the output of the determining section. The rotational speed of the drum 2 may not increase due to pulley loosening, belt slipping, or the like.
乾燥行程では、まず乾燥フラグの有無を調べ、フラグが
立っていなければ、乾燥禁止部29が乾燥作業を禁止し
、表示・報知装置25によって乾燥不可を表示・報知す
る。In the drying process, the presence or absence of a drying flag is first checked, and if the flag is not set, the drying prohibition section 29 prohibits the drying operation, and the display/notification device 25 displays/notifies that drying is not possible.
フラグが立っていれば、乾燥制御部30は、乾燥時間を

F制御する。If the flag is set, the drying control unit 30 rotates the drum 2 at low speed, drives the blower 7, and operates the cooler 8 and heater 9 until the timer 27 counts the drying time. Then, the temperature measured by the temperature sensor 10 is 38°C.
Turn on and off the heater 9 so that the temperature is below ~36℃ or higher.
F control.
この間、クーラ8では、溶剤蒸気を凝縮して回収し、水
分離器11に送る。During this time, the cooler 8 condenses and collects the solvent vapor and sends it to the water separator 11.
