Spray type water-cooled tuyere blast cupola

The utility model relates to a spray type water-cooled tuyere furnace cupola, which is a cast iron melting device and is mainly composed of a furnace cupola body, spray coolers, water-cooled tuyeres, and a slag-iron separator. A circle of water-cooled spray coolers of the casing of a cooling furnace cupola is arranged on the peripheral wall at the middle part and the middle upper part of the furnace cupola body, the middle lower part of the furnace cupola body is evenly distributed with two rows of water-cooled tuyeres along the furnace body, and the bottom part of the furnace cupola body is provided with a pressure slag separating machine. The water-cooled tuyeres can insert within 100 millimeters in the furnace cupola. The distance H3 between the two rows of water-cooled tuyeres is 0.3 to 1.2 times of the inner diameter D of the furnace cupola, and the row of water-cooled tuyeres at the lower surface is arranged at the top end of a furnace cupola hearth.
