Described slag body chamber furnaced is oval, and its side is respectively equipped with slag notch and molten metal outlet.
The invention has the beneficial effects as follows: this blast electroslag furnace separates oxygen-enriched air blast fusing and combines with the electric heating copper ashes, electronic waste copper alloy after treatment pours into bulk, can make electrolytic copper material or cast copper alloy raw material, the slag main component is alundum (Al and silica, can make cement raw material through Water Quenching, dedusting ash can spray into melting furnace with oxygen-enriched air by the bottom puff prot and melt once more, thereby reaches that electronic waste is innoxious, the processing intent of minimizing, resource.In addition, organic matter of the present invention burns and complete decomposition, the metal recovery rate height.
Description of drawings
Fig. 1 is a structure chart of the present invention.
The specific embodiment
As shown in Figure 1, present embodiment mainly is made up of screw(-type) feeder 1, air blast melting furnace 3, slag body chamber furnaced 4, electrode lifting mechanism 8 and electric supply installation 2, and electric supply installation 2 is made up of furnace transformer 2-1 and rectifier 2-2 in this example.Described screw(-type) feeder 1 output is communicated with air blast melting furnace 3, and air blast melting furnace 3 is directly installed on slag body chamber furnaced 4 tops, and is attached thereto logical; Described slag body chamber furnaced 4 bottoms are provided with stretches out the outer graphite cake 5 of body of heater, top one side is installed bell 6 under the semicircle that is provided with electrode insertion mouth, and be connected with furnace sealing, graphite electrode 7 one ends insert a mouthful oblique cutting by electrode and go in the slag body chamber furnaced 4, this graphite electrode is fixed on the electrode lifting mechanism 8 of being located at electroslag furnace one side, and can move up and down with the lifting of electrode lifting mechanism 8; Described graphite cake 5 and graphite electrode 7 are electrically connected on rectifier 2-2 and the furnace transformer 2-1 successively by water-cooled cable 9, during work, alternating voltage is successively through providing the operating voltage of 40-80V for respectively behind furnace transformer 2-1, the rectifier 2-2 graphite cake 5 and graphite electrode 7.
Described air blast melting furnace 3 is a cylindrical shape, the last bell 10 of top mounting strap steam vent, and two rows oxygen-enriched air jet pipe 11 is installed in the side, and every row installs 5, and in the course of work, the oxygen enrichment percentage that sprays into gas is between 0-60%.
