High-frequency induction heating device for water-cooled crystal bar melting

Abstract

The invention discloses a high-frequency induction heating device for water-cooled crystal bar melting. A high-frequency induction heating device for water-cooled crystal bar melting comprises a high-frequency coil. The two ends of the opening side of the high-frequency coil are detachably connected with the two water-cooled electrodes through bolts respectively. The water-cooled electrode further comprises a water-cooled flange, a through hole for the water-cooled electrode to extend and penetrate through is formed in the water-cooled flange, an insulating ring is clamped between the through hole and the water-cooled electrode, the outer side of the water-cooled electrode is in threaded connection with a first locking nut, a supporting groove for the first locking nut to be embedded is formed in the insulating ring, and the water-cooled electrode is sleeved with an electrode locking nut. The electrode locking nut is in threaded connection with the water-cooled flange, and the water-cooled electrode is connected with an electrode plate used for being connected with an external cable; the water-cooled electrodes are provided with first water-cooled channels, and the two ends of the arc-shaped cooling channel of the high-frequency coil are in butt joint with the first water-cooled channels of the two water-cooled electrodes respectively. The structure is more integrated, and cooling unitization is achieved.
