ABSTRACT:
A hot solvent tank for cleaning various objects such as metallic parts is provided. The solvent is a bio-degradable detergent aqueous solution which is environmentally acceptable. The solvent tank is an open top steel barrel mounted on casters for easy moving and employs a thermostatically controlled heating element. A bottom drain valve is connected at the bottom. The various parts to be cleaned may be immersed in the solvent and supported by chains or baskets hooked over the rim at the top of the barrel. The drain valve may be connected to an accessory cleaning unit comprising a pump and replaceable automotive filter for pumping solvent through a hose and flow through a brush for cleaning parts supported above the solvent at the top of the tank. The filter, which can be discarded when dirty, is effective for removing heavy metal contaminants and providing a purified recirculating solvent. When the pump and filter are employed, the solvent is kept clean and the filter, when dirty, is replaced and recycled for scrap metal. The problem of waste disposal of sludge is eliminated.
