The invention discloses a coal-fired ignition kiln head for a manganese ore sintering machine. The coal-fired ignition kiln head comprises a primary combustion chamber, a secondary combustion chamber and an ignition chamber. The primary combustion chamber and the secondary combustion chamber are communicated. The secondary combustion chamber is communicated with the ignition chamber and provided with a fire grate, a soft coal combusting engine and an air blower corresponding to the primary combustion chamber. The ignition chamber is arranged on sintering machine hoppers stepping in the front and back direction and comprises a clamping sleeve provided with an upper arch layer and a lower arch layer. The front-back length of the clamping sleeve corresponds to the total length of a plurality of sintering machine hoppers below the clamping sleeve. The left-right width of the clamping sleeve corresponds to the width of each sintering machine hopper. The lower arch layer in the clamping sleeve is provided with a plurality of sets of fire distributing bands in a front and back mode, wherein the fire distributing bands correspond to the sintering machine hoppers respectively. Each set of the fire distributing band comprises front and back bands in the left and right direction. According to the coal-fired ignition kiln head, low-price soft coal is used as fuel, generated high-temperature flue gas can be directly used for ignition, the ignition effect is good, and the operation cost is low.
Description
(1) Technical field: [0001] The invention relates to smelting equipment, in particular to a coal-fired ignition kiln head for a manganese ore sintering machine. (2) Background technology: [0002] At present, manganese ore is mostly placer, because the particles are too small to be directly used as raw material for blast furnace. Therefore, manganese placer needs to be sintered by manganese ore sintering machine first, and then it can be smelted in blast furnace after it becomes a large piece of ore. [0003] The manganese ore sintering machine needs an ignition device for igniting the anthracite mixed in the manganese placer. At present, manganese ore sintering machines use gas ignition devices. If there is a blast furnace in normal operation nearby, blast furnace gas can be used as fuel. [0004] But not every manganese ore sintering machine has a blast furnace near it, and not every blast furnace can operate normally all the time. Therefore, the matching ignition device ...
