The number of applying for a patent is that 200710021519.8 specification discloses a kind of rake type drier; It mainly adopts hollow spindle to be installed in the tank body inner core; On an empty stomach drag head connects raking arm being installed on the hollow spindle symmetrically; Utilize the tail gas of equipment heating to import hollow shaft and empty stomach drag head, steam consumption quantity is little, and heating is fast.But the shape of its raking arm does not have improvement, and the inverting action of material is failed to bring into play.
Summary of the invention
Goal of the invention: overcome the low defective of conventional dryer drying efficiency, provide a kind of stirring evenly, the thorough rake type drier fast of drying.
Technical scheme: rake type drier of the present invention; Other parts that contain body fuselage, hothouse, rotating shaft, raking arm, steam outlet, vacuum equipment, material outlet and conventional drying machine; Raking arm evenly distributes and is connected in the rotating shaft; Raking arm is made up of rake root and drag head, and raking arm is fist type, T type or inverted L type; On the direction of drag head, the cross-sectional area of rake root reduces gradually by rotating shaft, and the cross-sectional area of drag head is greater than the cross-sectional area of rake root afterbody; Drag head perpendicular to the projection width in the plane of rotating shaft greater than the rake projection width of root in this plane.
The projection of described drag head in being parallel to the plane of rotating shaft is wide or bigger with the projection of rake root afterbody (rake root and drag head connecting portion) in this plane.
There is water pipe in the raking arm described raking arm inside, and there is water pipe in the rotating shaft rotating shaft inside, and is interconnected, and is connected with outer pipeline, supplies input hot water or cold water.
Can contain the semi-canal type heating pipe line in the described body fuselage, feed steam or deep fat in this pipeline, the material thermal source is provided.
Described raking arm is movably connected in the rotating shaft, raking arm can along rotating shaft axially about respectively wave 0-15 °, further be convenient to stir the upset material.
The wall surface material that the inner hothouse of described body fuselage contacts with material is preferably stainless steel or carbon steel, and corrosion resistance and hear resistance are good.
Beneficial effect: material of the present invention is in airtight hothouse; Make heat energy lead through the heating of hothouse external jacket in material; Simultaneously through be fixed in the rotating shaft about to the raking arm material that constantly overturns; Make and material surface and inner moisture gasification, reach the equipment of dry materials again by the steam of high-vacuum apparatus extraction hothouse.This equipment can be widely used in the dried of pulpous state, paste, granular, powdery and fiberous material, is the desirable drying equipments of industry such as chemical industry, food, medicine, dyestuff.
