以刮板式生物质粉喂料机为研究对象,通过实验研究与数值拟合的方法,对该装置的喂料特性进行分析。研究结果表明:在刮板转速低于37r/min时,实测喂料速率比理论值略小,在37~55r/min区间内,实测喂料速率比理论值略大,进一步增加转速到55r/min以上时,喂料速率增加趋于缓慢,低于且逐渐远离理论值。相同工况状态下,物料粒径越小,喂料速率越大,且料筒内原始料位越高,喂料速率越高。 Taking scraper biomass powder feeder as the research object, the feeding characteristics of the device were analyzed by experimental research and numerical fitting method. The results show that when the rotating speed of the scraper is lower than 37r / min, the measured feeding rate is slightly smaller than the theoretical value. In the range of 37-55r / min, the measured feeding rate is slightly larger than the theoretical value, further increasing the rotating speed to 55r / min or more, the feed rate increase tends to be slow, below and gradually away from the theoretical value. Under the same working condition, the smaller the particle size of the material, the higher the feeding rate, and the higher the original material level in the barrel, the higher the feeding rate.
