Abstract:
1. An apparatus for recycling liquid quenching medium, comprising: a quenching chamber configured to receive quenching medium, a spray washing chamber, an immersion cleaning tank, a rinsing chamber, a liquid storage tank configured to collect liquid from the spray washing chamber, wherein a molten and mixing tank, wherein the molten and mixing tank is located above the quenching chamber, a medium circulation pump located in the quenching chamber, a quenching medium delivery pipeline, wherein the quenching medium flows into the molten and mixing tank driven by the medium circulation pump through the quenching medium delivery pipeline, and a medium backflow pipeline, wherein the medium backflow pipeline transports the quenching medium from the molten and mixing tank to the quenching chamber, and wherein the medium delivery pipeline, the media backflow pipeline, the molten and mixing tank, and the quenching chamber are in fluid communication, and serve for recovering and recycling the quenching medium, a thermal insulation door, wherein at one side of a thermal insulation door a liquid transportation pipeline is connected with a circulation pump located in the liquid storage tank, and at another side of the thermal insulation door, a pipeline that transports the spray rinsing water is connected with the spray rinsing chamber, and a spray rinsing water by-pass that connects the molten and mixing tank with the spray rinsing water pipeline, wherein an electromagnetic valve in the spray rinsing water by-pass is installed to connect a temperature controller, and wherein the temperature controller is connected with the quenching chamber.
