Description
技术领域
本发明专利主要应用于生物质碎料,有机肥,糠醛渣,酒糟,中药渣等物料的烘干。
背景技术
目前,传统的烘干机构造主要是单筒和三筒的烘干机,这两种烘干机体型大,散热面大,烘干机采用带火星的烟气热风直接进入烘干筒内,这样就很容易着火,安全隐患大,不符合环保和消防要求,不能烘干生物质屑、末等物料。这两种烘干机不仅烘干效率低,烘干成本高,而且只能烘干低水分物料。
另外,最近有人发明了一种真空烘干机,相比传统烘干机外筒旋转密封不好的问题,他在此进行了改进,体形也比传统的烘干机要小,他采用在烘干机外筒底部局部加热,热风不进入烘干筒内,这样虽然解决了烘干筒内火灾安全隐患,但其设置在烘干机底部采用直燃方式为烘干筒局部加热,依然有火灾隐患。此种烘干机也是存在烘干效率低,烘干成本高,只能烘干低水分物料。
发明内容
为了克服现有烘干机热损耗大,烘干效率低,烘干成本高,不能烘干高水分物料,以及不符合环保和消防要求的不足,本发明专利提供一种箱筒式烘干机,不仅解决了火灾安全隐患,而且降低了热损耗,提高了烘干效率,降低了烘干成本,并且可烘干高水分物料,同时满足环保和消防要求。
本发明专利解决其技术问题所采用的技术方案是:在圆形烘干筒下部设有方型箱体,生物质热风锅炉产生的烟气从方形箱体一侧的前端进入,方形箱体分割有多个回转区域利于烟气余热充分对圆形烘干筒进行加热,烟气在尾端折回从前端另一侧排出,排出的烟气通过净化后可输入圆形烘干筒内,再一次回收利用。热风锅炉的清洁热风通过热风管轴进入到圆形烘干筒内,热风管轴上有多根不同方向的热风支管,支管上带有风道孔,清洁热风通过支管在管轴旋转带动下形成旋转气流充分烘吹物料。在圆形烘干筒后端设有专门用于排潮的装置,及时将烘干筒内的在烘干过程中产生的潮气排出,另外,对烘干机整体进行了保温处理。具体做法是:生物质热风炉排出的高温烟气通过方形箱体前端进入,从后端折回到前端排出,为上面的圆形烘干筒加热,热风炉产生的清洁热风通过风管进入圆形烘干筒内,通过风管上的风道均匀烘吹物料,烘干过程中产生的潮气,通过圆形烘干筒后端的排潮装置排出。
本发明专利的有益效果是,烟气余热得到了充分回收利用,提高了烘干效率,降低了烘干成本,可以一次烘干高水分物料,寒冷的冬季不影响生产,不受气候影响。
附图说明
下面结合附图和实施例对本发明专利进一步说明。
图1是本发明专利的结构示意图
图2是箱筒式烘干机实施例的纵剖面构造图
图3是箱筒式烘干机实例的左侧纵剖面构造图
具体实施方式
在图1中,热风锅炉(1)产生的烟气余热通过烟道管(2)进入到方形箱体(11)对圆形烘干筒(10)进行加热,热风锅炉产生的清洁热风通过热风管(3)通过热风管轴(4)进入圆形烘干筒内,电动机(5)通过链条带动热风管轴(4)旋转,烘干物料由进料口(6)进入圆形烘干筒内,再烘干过程中产生的潮气通过通风口(7)和排潮装置(8)向外排出,烘干好的物料通过蛟龙传送到烘干筒外。
在图2所示实例中,方形箱体(11)设有隔板(13)用于分隔出回转区域,以烟气在箱体内滞留的时间,提高烟气余热的充分回收利用,热风锅炉产生的清洁热风通过热管轴上的带有风道的热风支管(16)直接哄吹物料,电机(5)驱动热风管轴(4)带动热风支管(16)旋转,从而形成旋转气流哄吹物料。潮湿的物料从进料口(6)进入圆形烘干筒(10)内,在热风管轴(4)上的螺旋叶片(14)旋转带动下向前移动,烘干好的物料从烘干筒尾端的输料蛟龙(9)排到烘干筒外。排潮管(15)与排潮装置(8)相连,将烘干筒内烘干过程中产生的潮气向外排出。
在图3所示实例中,热风炉的烟气从方形箱体(11)一侧进入,从另一侧排出,热风管轴(4)上连接热风支管(16)和螺旋叶片(14),热风管轴(4)带动热风支管(16)和螺旋叶片(14)旋转,从而形成旋转气流哄吹物料和推动物料向前移动,最后排出到烘干筒外。
