The invention provides a blasting belt-type
sintering machine and a method, for producing sinter, of the blasting belt-type
sintering machine. A
material distribution mechanism I, an igniter, a
material distribution mechanism II, an air draft and dust-removal
flue and a discharging device are sequentially arranged on an upper-layer
sintering cart way from a
machine head to a machine
tail, wherein the lower portion of the igniter is communicated with an air draft ignition pipeline through a wind box, the lower portion of the air draft and dust-removal
flue is connected with a sealing cover, the sealing cover is arranged on the upper-layer sintering
cart way, the sealing cover is communicated with a sintering blasting pipeline through the wind box at the lower portion of a
cart, and a dust-falling
pipe is arranged at the lower portion of the sintering blasting pipeline. According to the sintering machine, through two times of feeding, the thickness of a material layer can be improved to about 1-1.5m, fuel is combusted thoroughly through blasting sintering, the
electricity-saving effect is obvious, and the
electricity is saved by three fourths when air draft is changed into blasting. In the air draft process, the cart and grate bars make direct contact with sintering high-temperature
smoke, the temperature is high, and the cart and the grate bars are deformed and damaged easily. After air draft is changed into blasting, the cart and the grate bars make contact with room-temperature blasting air, the temperature is low, and therefore the cart and the grate bars are not damaged easily.
