Title:
PULSED POWER CORE SAND-PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/136475
Kind Code:
A1
Abstract:
[Problem] To provide a pulsed power core sand-processing device that is safe and efficient. [Solution] A casting (W) and the discharge section (21) of a positive electrode (17) are disposed facing each other across a gap and the power-receiving section (22) of the negative electrode (18) is made to contact the casting (W). Next, a lead (25), which connects to a pulsed power-generating unit, is connected to the positive electrode (17), a grounding lead (26) is connected to the negative electrode (18), and a high voltage is applied on the positive electrode (17). A spark (27) is generated between the discharge section (21) of the positive electrode (17) and the casting (W), the shock wave is transmitted to the core (28) inside the casting (W), the core (28) disintegrates, and the sand configuring the core (28) is released into water inside a water tank (3).
