Claims

[Scope of utility model registration request]

A slop tank is provided, and a pump is provided for drawing oil in the oil tank through a first suction pipe and conveying it to a predetermined location via a discharge pipe, one end of which communicates with the above-mentioned discharge pipe, and the other end of the tank. A circulation pipe having a discharge port opening into the slop tank is provided, an eductor is interposed in the circulation pipe, and one end is connected to the first
A second suction pipe is provided that communicates with the suction pipe and has a suction port at the other end located at a lower part of the slop tank, and has one end that communicates with a location upstream of the second suction pipe communication portion of the first suction pipe. A third suction pipe is provided, the other of which is connected to the eductor, and includes a portion upstream of the eductor of the circulation pipe, a portion between the second and third suction pipes of the first suction pipe, and the second suction pipe and the third suction pipe. An opening/closing valve is interposed in each, a flow rate adjustment valve is provided at a location downstream of the circulation pipe communication portion of the discharge pipe, a first flow meter is provided at one location downstream of the eductor of the circulation pipe, and a flow rate adjustment valve is provided at a location downstream of the eductor of the circulation pipe, and a □A second flow meter is provided, and a control device is provided that inputs and calculates the flow rate values of the two flow rate needles and controls the flow rate adjustment valve so as to maintain the ratio of these two flow rate values constant. A soaking liquid device featuring:
