<p>PROBLEM TO BE SOLVED: To provide a multi-function-type oil treatment device which enables the draining operation of a fouled oil from an oil vessel to be performed rapidly and easily purifies the oil and the oil vessel by circulating the oil contained in the oil vessel while filtering it, and further, separates the sucked oil by sedimentation to return its supernatant oil to the vessel through an efficient treatment. SOLUTION: A recovery tank 3 which stores an oil contained in an oil vessel 7 through a filtration member 6a to separate it by sedimentation and a pump 4 whose suction end and discharge end can be switched, are mounted aboard a truck 1. In addition, a common receiver fitting tool 14 to which an integrating fitment 13 provided on the tips of liquid guide pipes 11, 12 extending from the suction end or the discharge end of the pump 4 can be fitted, is arranged on a discharge aperture 7a opened at the bottom part of the oil vessel 7, an inlet aperture in an auxiliary inlet tool to the recovery tank 3, a discharge aperture 8 for a supernatant oil in the recovery tank 3 and a discharge aperture 9 for a precipitate, respectively. Thus, it is possible to simply switch from the oil suction operation to the oil discharge operation or vice versa depending upon the purpose of the operation.</p> |
