Embodiment Construction

[0009] As shown in Figure 1, this embodiment is mainly composed of a screw feeder 1, a blast melting furnace 3, a slag body separation furnace 4, an electrode lifting mechanism 8 and a power supply device 2. In this example, the power supply device 2 consists of an electric furnace transformer 2- 1 and rectifier 2-2. The output end of the screw feeder 1 communicates with the blast melting furnace 3, and the blast melting furnace 3 is directly installed on the upper part of the slag body separation furnace 4 and communicates with it; the bottom of the slag body separation furnace 4 is provided with a The graphite plate 5 outside the body is equipped with a semicircular lower furnace cover 6 with an electrode insertion port on the top side, and is sealed and connected with the furnace body. One end of the graphite electrode 7 is obliquely inserted into the slag body separation furnace 4 through the electrode insertion port. The electrodes are fixed on the electrode lifting mecha...

Abstract

The invention relates to a special blowing electroslag furnace for treating electronic waste. The invention provided special blowing electroslag furnace for treating electronic waste can thoroughly incinerate of and decompose the waste, and has high recovery rate. The technical scheme to solve the problem is that: the special blowing electroslag furnace for treating electronic waste has spiral feeding machine, power supply device, and which is characterized in that an output terminal of the spiral feeding machine is connected to blowing melting furnace which is fixed to upper portion of a slag separating furnace and connected to the same, and the slag separating furnace has a black lead plate extending out of the furnace body and disposed at the bottom of the furnace, and a lower furnace cover having electrode holes and disposed at one side of top of the furnace and seal connected to the furnace body. Black lead electrodes are fixed at electrode elevating mechanism disposed at one side of the slag furnace, and one end of the electrode inserts into the slag separating furnace via the electrode hole, and the black lead plate and the black lead electrodes are electrically connected to rectifier and electric furnace transformer in sequence by water cooling cable. The invention can be used for recovery, disinfection, waste utilization of metal, nonmetal, and combination thereof.

Description

technical field [0001] The invention relates to an incinerator, in particular to a special blast electroslag furnace for processing electronic waste. It is suitable for large-scale recovery, disinfection and waste utilization of metals, non-metals and their combinations. Background technique [0002] Electronic waste (such as circuit boards, copper-clad laminates, etc.) will often have an unimaginable negative impact on the ecological environment if they are not disposed of in a timely and proper manner after losing their use value. One of those puzzles that feels tricky and is working hard to crack. Generally, electronic waste is treated by incineration, recycling, disinfection and waste utilization. For example, the Chinese invention patent No. ZL03141887.2 discloses a "solid waste incinerator and dry distillation and incineration process". This incinerator is made up of two parts, dry distillation, incineration device I. The center of the bottom of the furnace body is e...
