1-2. (canceled)
An apparatus for recycling liquid quenching medium, comprising:
- a quenching chamber configured to receive quenching medium, a spray washing chamber, immersion cleaning tank and rinsing chamber, a liquid storage tank configured to collect liquid from the spray washing chamber,
- and a molten and mixing tank, wherein the quenching chamber and the molten and mixing tank are in fluid communication.
A system to recycle a quenching medium used in the manufacture of metal parts comprising:
- a product delivery means to deliver product to a quenching chamber;
- a quenching chamber configured to receive quenching medium and said product;
- a spray washing chamber, immersion cleaning tank and rinsing chamber, a liquid storage tank configured to collect liquid from the spray washing chamber, and
- a molten and mixing tank in fluid communication with said quenching chamber, configured to receive used quenching medium and a conduit to deliver spray rinsing water to the molten and mixing tank and a temperature actuated value to modulate flow of fluid thought said conduit to deliver spray rinsing water to the molten metal mixing tank and
- a medium backflow pipeline to transport the medium from said molten and mixing tank to the quenching tank for reuse.
