Heat supply adjuster for hot-blast stove

The invention provides a heat supply adjuster for a hot-blast stove and relates to the technical field of hot-blast stoves. The heat supply adjuster comprises a rectangular air channel. A wind shield is arranged in the rectangular air channel. The two sides of the wind shield are installed on the side walls of the rectangular air channel through rotating shafts. The rotating shaft at one side of the wind shield penetrates through one side wall of the rectangular air channel and is connected with a rotary handle, a locking device is arranged at the inner side of the rotary handle, one side wall provided with the rotating shaft is provided with a plurality of locating grooves, the locating grooves are uniformly distributed in the semicircular track with the rotating shaft as the center, and elastic limiting devices matched with the locating grooves are arranged on the side face of the wind shield. According to the heat supply adjuster for the hot-blast stove, the blast capacity of hot wind can be adjusted, the heat supply adjuster has fixed multi-stage gears for adjusting the hot wind, all the gears are located accurately through the locating grooves, the wind shield can be accurately adjusted, and after the wind shield is adjusted, the wind shield can be locked through the locking device, and prevented from rotating under the effect of airflow.
