And there is an urgent need for a kind of rotary dryer, more preferable utilization rate of heat value and drying effect can be reached.
The content of the invention
The object of the present invention is to provide a kind of rotary dryer with multistage lifting blade, the present invention is using multistage lifting blade
Arrangement, lifting blade height increase, ensure that drying effect and reached more preferable utilization rate of heat value step by step.
The technical solution adopted in the present invention is：
A kind of rotary dryer with multistage lifting blade, including cylinder, vertical lifting blade, vertical circular arc lifting blade and incline
Oblique circular arc lifting blade, vertical lifting blade, vertical circular arc lifting blade and inclination circular arc lifting blade include the working plate being connected with each other
And bottom plate, bottom plate are installed on cylinder inboard wall, the work of the working plate circular arc lifting blade vertical with bottom plate, vertical of vertical lifting blade
Plate is vertical with bottom plate and top is arc-shaped, tilt the working plate of circular arc lifting blade and bottom plate is at an acute angle and top is arc-shaped, vertically
Lifting blade, the working plate equivalent width of vertical circular arc lifting blade and inclination circular arc lifting blade and height increase successively, vertical lifting
Plate, vertical circular arc lifting blade and inclination circular arc lifting blade are distributed on feed zone, intermediate region and the discharging region of cylinder respectively
And in the same direction.
Further, it is equipped with transition region between feed zone and intermediate region and/or intermediate region and discharging region
Domain, two kinds of adjacent lifting blades are interspersed in transitional region.
Further, bottom plate is equipped with mounting hole and at least two angle adjustable holes, bottom plate using mounting hole from it is different
After the cooperation of angle adjustable hole is fixed working plate can be made to be in different angles.
Further, it is equipped with vertical lifting blade, vertical circular arc lifting blade and inclination circular arc lifting blade for installing chain
Chain curtain mounting hole of the bar shaped into chain curtain.
Further, vertical lifting blade, vertical circular arc lifting blade and inclination circular arc lifting blade are cast using cast steel material
Form.
The beneficial effects of the invention are as follows：
The present invention is arranged using multistage lifting blade, and lifting blade height increases step by step, when material enters cylinder feed zone, water
Divide content highest, and the wind-warm syndrome that hot wind enters in cylinder is successively decreased from feed zone to discharging region, rotating speed unanimous circumstances
The linear velocity that the lower lifting blade of lower height is obtained is lower, and material subtracts successively from feed zone to discharging region residence time
It is few, it ensure that drying effect, meanwhile, the linear velocity from feed zone to discharging region lifting blade gradually steps up so that material is in
Acceleration mode step by step so that effective lifting area is lifted step by step, and the hot cavity of area and reduction of being scattered for being conducive to increase material is existing
As so that into being more evenly distributed, rationally on cylinder sectional area of the material in cylinder, reach more preferable calorific value and utilized
Rate.

Embodiment
The present invention is further illustrated with reference to the accompanying drawings and examples.
As depicted in figs. 1 and 2, a kind of rotary dryer with multistage lifting blade, including cylinder 4, vertical lifting blade 1,
Vertical circular arc lifting blade 2 and inclination circular arc lifting blade 3, as shown in figure 3, vertical lifting blade 1, vertical circular arc lifting blade 2 and inclination
Circular arc lifting blade 3 includes the working plate and bottom plate being connected with each other, and bottom plate is installed on 4 inner wall of cylinder, the work of vertical lifting blade 1
Make plate circular arc lifting blade 2 vertical with bottom plate, vertical working plate is vertical with bottom plate and top is arc-shaped, tilts circular arc lifting blade 3
Working plate it is at an acute angle with bottom plate and top is arc-shaped, vertical lifting blade 1, vertical circular arc lifting blade 2 and tilt circular arc lifting blade 3
Working plate equivalent width and height increase successively, as shown in Fig. 2, vertical lifting blade 1, vertical circular arc lifting blade 2 and tilting circle
Arc lifting blade 3 is distributed on the feed zone of cylinder 4, intermediate region and discharging region and in the same direction respectively.
The present invention is arranged using multistage lifting blade, and lifting blade height increases step by step, when material enters 4 feed zone of cylinder,
Moisture highest, and the wind-warm syndrome that hot wind enters in cylinder 4 is successively decreased from feed zone to discharging region, the consistent feelings of rotating speed
The linear velocity that the lower lifting blade of height is obtained under condition is lower, material from feed zone to discharging region residence time successively
Reduce, ensure that drying effect, meanwhile, the linear velocity from feed zone to discharging region lifting blade gradually steps up so that material
In acceleration mode step by step so that effective lifting area is lifted step by step, is conducive to increase be scattered area and the reduction heat cavity of material
Phenomenon so that into being more evenly distributed, rationally on cylinder sectional area of the material in cylinder 4, reached more preferable calorific value profit
With rate.
As depicted in figs. 1 and 2, in the present embodiment, transitional region, transition region are equipped between intermediate region and discharging region
Two kinds of adjacent lifting blades are interspersed in domain, in fact, can also individually be set between feed zone and intermediate region
Region is crossed, transition region can also be set at the same time between intermediate region and discharging region between feed zone and intermediate region
Domain.It is that material caused by linear velocity mutation is disorderly in order to prevent to set transitional region so that the change of linear velocity has certain
Continuity.
