Abstract
The invention relates to a special discharging device for a selenium vacuum melting apparatus. The device comprises a discharging tube, a positioning rack, a discharging block plate, a cooler and a handle, wherein one end of the discharging tube is directly connected with the material outlet of the selenium vacuum melting apparatus, the positioning rack sleeves the outer side of the tube wall at the other end of the discharging tube, and the discharging block plate is connected with the positioning rack and obstructs an outlet at the other end of the discharging tube; and the plate edge part of the discharging block edge is conical in shape, the edge of the conical discharging block plate forms a conical inclined plane edge, a slit distance S exists between the conical inclined plane edge and the inner wall of the outlet of the discharging tube, one side of the discharging block plate is connected with the handle, and the handle realizes the opening or closing of the discharging block plate through the connection of the positioning rack; and the outer side plate, close to the handle, of the discharging block plate is provided with the cooler, and the cooler is used for cooling the discharging block plate. The property of a selenium material is used to seal the discharging block plate and carry out discharging, so the problem of difficult discharging of the high-viscosity selenium material is solved.
Description
technical field [0001] The invention relates to a special discharge device used in selenium smelting equipment, in particular to a special discharge device for selenium vacuum smelting equipment, belonging to the field of equipment manufacturing. Background technique [0002] Selenium is an important semiconductor material with a melting point of 221°C and a boiling point of 685°C. The abundance of selenium in the earth's crust is only 0.05-0.09mg / kg, and no single selenium deposit with economic value has been found in nature. Selenium is usually associated with metal sulfide ores such as copper, lead, and nickel. The main source of selenium is the by-products produced during the smelting of heavy metal sulfide ores, while the amount of selenium produced from copper electrolytic anode slime and copper sulfide ore smelting dust accounts for about 90% of the total selenium output, and the rest comes from the refining output of lead, cobalt and nickel It is recovered from the ...
