Electric furnace for treating zinc-containing tailing slag

Equipment use:
The equipment adopts fire smelting technology, adding mixed materials containing zinc oxide, coke, solvent, etc. into the furnace, using electric energy to heat zinc materials to distill zinc steam, and condensing zinc steam through the condenser to produce crude zinc products.

Equipment Overview:
1. The equipment is designed and manufactured according to GBl0067.1-4 "Basic Technical Conditions for Electric Heating Equipment".
2. The main technologies used in this equipment are:
3. Fully closed structure design;
4. Plate water cooling furnace cover:
5. Energy-saving short net;
6. Copper tube type hydraulic lifting type conductive cross arm;
7. Water-cooled cable in large section;
8.PLC automatic control system;

The shell is made of 20 thick steel plate (Q235) welded, the shell is cylindrical, and the bottom is installed on the foundation I-steel. The top of the furnace shell is provided with a sand sealing groove.
The furnace shell is provided with a manual slagging operation door, a slagging tank and an iron tapping tank.
The slag chute of the furnace body adopts a water-cooled chute, which is connected with the flange of the slag outlet.
Furnace shell inner lining refractory.

The electrode lifting device is composed of a conductive cross arm, a column, an electrode lifting hydraulic cylinder (built into the column steel pipe), a trailer, a guide wheel, etc.

The electrode lifting device has the following advantages:
· The conductive transverse arm is flexible in lifting, the system has small inertia and good rigidity;
· Greatly simplified structure, good insulation performance, high reliability;
· Can easily and reliably clamp and relax the electrode;
· The electrode clamping force is large, and the clamping head is not easy to spark;
· The electrode lock is a water-cooled component, which will not cause the electrode to slide due to thermal expansion in the high temperature area.
