技术介绍
现有技术中的带式环流干燥机,包括机体及位于机体内的输送带、循环风机,输送 带水平设置,输送带长度方向的一端设有进料斗,另一端为出料端,输送带上铺设有物料 层,输送带下方为配风室,配风室的热风进口位于输送带宽度方向的一端,循环风机的出口 风道垂直向下与配风室的热风进口相连通,循环风机的吸口风道与物料层的上方风道相连ο物料层随输送带前进,经加热器加热后的空气,在由循环风机驱动下,由输送带下 部垂直上吹,物料的阻力使物料层上下产生压差,该压差使高温空气能穿过物料层,并带走 物料中的水分,使其干燥,热空气的流动方向与物料的前进方向呈“十”字交叉。该带式环流干燥机存在如下不足之处1、热空气被循环风机推动后,一边沿输送带下方的配风室向前流动即沿着输送带 的幅宽方向流动,一边穿过物料层向上流动,由于热空气的流速较高,导致配风室中沿输送 带的幅宽方向风压分布不均勻,从而使穿过物料层的气流不均勻,最终影响物料烘干均勻 性。2、高速气流在循环风机出口风道与配风室热风进口相连接的拐弯处产生涡流,气 ...
