Abstract
Устройство для плавки меди, включающее корпус (100) печи, загрузочное отверстие (101), отверстие (106) для выпуска дымовых газов, отверстие (102) для выпуска шлака, канал (103) для выпуска медного штейна и вентиляционный патрубок (104) для первичного воздуха. В корпусе (100) печи последовательно снизу вверх расположены слой (112) медного штейна, слой (113) шлака и газовый слой (114). Загрузочное отверстие (101) расположено на верхней стенке корпуса (100) печи. Отверстие (106) для выпуска дымовых газов расположено на верхней стенке корпуса (100) печи. Отверстие (102) для выпуска шлака расположено на одном конце корпуса (100) печи. Канал (103) для выпуска медного штейна расположен на конце корпуса (100) печи, противоположном отверстию (102) для выпуска шлака, и канал (103) для выпуска медного штейна размещен в нижней части слоя (112) медного штейна. Вентиляционный патрубок (104) для первичного воздуха размещен на боковой стенке корпуса печи, соответствующей слою (113) шлака, и его используют для вдувания обогащенного кислородом воздуха в слой (113) шлака. Размеры внутренней стенки в направлении по ширине, соответствующие слою (113) шлака, составляют более 2,5 м и меньше или равны 4,5 м, так чтобы увеличить объем переработки концентратов в одной печи, тем самым повышая производительность труда и снижая эксплуатационные расходы.A device for melting copper, including a furnace body (100), a feed opening (101), a flue gas outlet (106), a slag outlet (102), a copper matte outlet (103) and a vent (104) for primary air. In the furnace body (100), a layer (112) of copper matte, a layer (113) of slag and a gas layer (114) are sequentially located from bottom to top. The feed opening (101) is located on the upper wall of the furnace body (100). A flue gas outlet (106) is located on the upper wall of the furnace body (100). The slag outlet (102) is located at one end of the furnace body (100). A copper matte discharge channel (103) is located at the end of the furnace body (100) opposite to the slag discharge hole (102), and a copper matte discharge channel (103) is located in the lower part of the copper matte layer (112). A primary air vent (104) is located on the side wall of the furnace body corresponding to the slag layer (113) and is used to blow oxygen-enriched air into the slag layer (113). The dimensions of the inner wall in the width direction corresponding to the slag layer (113) are more than 2.5 m and less than or equal to 4.5 m, so as to increase the volume of concentrate processing in one furnace, thereby increasing labor productivity and reducing operating costs.
