Gravity flow dryer

Abstract

The invention relates to a gravity flow dryer which is high in thermal efficiency, low in energy consumption, high in drying speed, good in drying quality and small in floor area, and produces little dust. The gravity flow dryer comprises a barrel, drying caps, drying trays, a blanking funnel, a blanking plate, a discharge valve and an electromagnetic vibrator. The barrel is internally provided with the drying caps and the drying trays, high-pressure hot air passes through the drying trays and the drying caps from bottom to top and perform sufficient heat exchange with a material layer which flows to above the hot air and has certain thickness during a task, so that drying and dehydration of a drying article are accomplished.

Description

technical field [0001] 本发明涉及一种干燥设备,尤其是由筒体、干燥帽、干燥盘、下料板、进气管、排气管、电磁振动器等组成的自流式烘干机。 Background technique [0002] 目前市面上使用的滚筒式烘干机的构造是由筒体、滚圈、托轮、大齿轮、减速机、尾罩组成。将热风从筒体进料端进入、废气从筒体出料端排出,靠减速机通过大齿圈带动筒体旋转把物料抛起与热风接触达到干燥目的,但是这种方式具有粉尘大、耗能多、占地面积大、卫生标准差的缺点。 Contents of the invention [0003] 本发明的目的是提供一种热效率高、耗能少、烘干速度快、干燥质量好、粉尘少、占地面积小的自流式烘干机,为达到上述目的,本发明的自流式烘干机由排气管、集气室、下料斗、筒体、干燥帽、干燥盘、下料板、进气管、出料阀、弹簧、电磁振动器、机架等组成。采用这种结构后,工作时筒体内的烘干物在各干燥帽和干燥盘上及往下流动的空间里能与设置在机外的高压鼓风机从进气管鼓进来的高压热空气从下至上数次穿过干燥物时进行充分的热交换,而后与该高压热空气从最上层的最湿的干燥物进行热交换后由机外引风机排出机外,用这种方式烘干可大幅提高热效率,减少能量消耗及粉尘产生,并提高干燥质量和减少占地面积。 Description of drawings [0004] 下面结合附图和实施例对本发明作进一步说明,附图是本发明实施例局部剖视构造示意图:图中:(1)排气管,(2)下料斗,(3)集气室,(4)中心孔,(5)螺栓,(6)下料管,(7)挡料板,(8)干燥帽,(9)加强圈<一>,(10)支承杆,(11)干燥盘,(12)下料口,(13)筒体,(14)加强圈<二>,(15)下料板,(16)进气管,(17)出料口,(18)弹簧,(19)底板,(20)电磁振动器,(21)出料阀,(22)机架。 detailed description [0005] 图中,筒体(13)是由金属板制成的圆筒体;筒体(13)内设置有数个干燥盘(11)、干燥盘(11)是用多孔板制成上大下小的圆锥盘、下端中间设置有下料口(12)、上端周边设置有加强圈<二>(14)并用焊接方式相互固定连接。干燥盘(11)上方设置有数根支承杆(10)并用...

AI Technical Summary

Problems solved by technology

The hot air enters from the feed end of the cylinder, and the exhaust gas is discharged from the discharge end of the cylinder. The reducer drives the cylinder to rotate through the large ring gear to throw the material up and contact with the hot air to achieve the purpose of drying. However, this method has the advantages of large dust and energy consumption. Disadvantages of large capacity, large floor space and poor sanitation standards
