Patent ID: 8119060

Claim:
A solder recovery device, comprising: a melter which melts solder dross stored in a melting crucible; an agitation unit which agitates the melted solder dross, so as to separate the melted solder dross up and down into an oxidized residue and a recycled solder in the melting crucible, said agitation unit including a first blower member configured to lower oxygen density in said solder recovery device by blowing a gas towards the melted solder dross while the agitation unit agitates the melted solder dross; and a suction unit which sucks the oxidized residue generated by the agitation, the suction unit sucking the oxidized residue in an upper portion of the melting crucible to be removed, wherein the first blower member has an exit orifice disposed to be above an upper surface of the melted solder dross and blows the gas in a generally downward direction towards the upper surface of the melted solder dross while the agitation unit agitates the melted solder dross, and the suction unit includes a second blower member that has an exit orifice disposed above an upper surface of the oxidized residue of the melted solder dross, the second blower member being configured to blow a gas in a generally downward direction towards the upper surface of the oxidized residue, such that the gas contacts the upper surface of the oxidized residue and thereby causes the oxidized residue to move towards the suction unit the suction unit further includes a lid member which opens and closes the opening of the melter.
