ABSTRACT:
Apparatus for recovering solvents used for cleaning machine parts and the like from the water used to wash the cleaning solvent from the parts. A fluid-receiving tank has a screen covering the open top of the tank for supporting a part to be cleaned. A splash guard projects above the screen on the back and sides of the tank. A shallow tray is slidably mounted on the tank beneath and closely adjacent to the screen for collecting sludge during a cleaning operation with the water and cleaning solvent overflowing the tray and collecting in the tank below. An inverted U-shaped drain pipe is mounted on the bottom wall of the tank with the inlet of the pipe located closely adjacent to the bottom wall within the tank and the outlet being located externally of the tank beneath the bottom tank wall. When the depth of liquid in the tank rises above the curved portion of the drain pipe, the water, which is heavier than the cleaning solvent, will flow through the drain pipe and out of the tank with the cleaning fluid remaining in the tank. A signal tube is mounted on the tank and has its inlet level a short distance above the curved portion of the drain pipe to collect solvent flowing through the tube in a receptacle for reuse while collecting the wash water flowing through the drain pipe in another receptacle.
