Description
Technical field
The present invention relates to a kind of drying materials equipment, particularly relate to a kind of novel barrel configuration for dehydrator, should
Barrel configuration is mainly used in the drying of ore in sand form.
Background technology
At present, what the drying of ore in sand form was commonly used is single-cylinder type rotary dryer.As it is shown in figure 1, prior art single-cylinder type
The main body of rotary dryer is the cylinder 5 slightly tilting and turning round, and the upper end that cylinder 5 tilts is provided with charging aperture 1 and water
Vapor outlet 2；The lower end tilted is provided with discharging opening 4 and hot gas inlet 3.Its operation principle is: wet stock adds from charging aperture 1 top
Enter, when cylinder topic 5 is internal, effectively contact with by the hot blast in cylinder 5 or heating wall and be dried, dry
Product after dry is collected from discharging port 4, and in dry run, material inscribes the slow rotation of 5 barrels by cylinder, at gravity
Move to relatively low one end from higher one section under effect.Cylinder is inscribed equipped with forward flight on 5 inwalls, it constantly material is taken up and
Spill down, make the contact surface of material increase, to improve dry rate and to promote material to move forward.Heat used in dry run
Carrier is generally hot-air, flue gas etc..
The rotating cylinder of single-cylinder type rotary dryer, its draw ratio is 6-12.Cylinder is the longest, the heat friendship that hot-air and material are carried out
Changing the most abundant, Outlet Gas Temperature is the lowest, but floor space is the biggest simultaneously, and needed for barrel body rotation, energy consumption is the most.
Summary of the invention
The problem that it is an object of the invention to overcome prior art to exist, it is provided that a kind of draw ratio is low, and floor space is little, dries
The barrel configuration for dehydrator that efficiency is high.
The technical solution adopted in the present invention is:
A kind of barrel configuration for dehydrator, including charging aperture, moisture outlet, hot gas inlet, discharging opening and cylinder；
Cylinder is obliquely installed, and is connected with rotating mechanism, and the upper end that cylinder tilts is provided with charging aperture and moisture outlet；The lower end tilted
It is provided with discharging opening and hot gas inlet；Barrel configuration also includes spiral separation structure；Spiral separation structure it is provided with in cylinder；Spiral
Separation structure is helical form；Spiral separation structure is positioned in cylinder, spiral partition and cylinder inwall compact siro spinning technology.
For realizing the object of the invention further, it is preferable that described spiral partition welds with cylinder inwall or logical
Cross casting integrated molding.
Preferably, described spiral partition and cylinder two ends are provided with spacing.
Preferably, described spiral partition and spacing 0.5-1m at cylinder two ends.
Preferably, described cylinder feed pipe reaches in cylinder, and described warm-air pipe reaches in cylinder, feed pipe and warm-air pipe
It is all fixing.
Preferably, the draw ratio of described cylinder is 4-8.
Relative to prior art, the invention has the beneficial effects as follows: the present invention uses helical structure by straight-through cylinder lumen
It is separated into the hot-air channel rotated around central shaft, in the case of equal barrel lenght, extends resident in cylinder of steam
Time, reduce the steam temperature of gas outlet, improve drying efficiency, floor space can be substantially reduced.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art single-cylinder type rotary dryer；
Fig. 2 is the present invention structural representation for the rotating cylinder of dehydrator.
Shown in figure: charging aperture 1, moisture outlet 2, hot gas inlet 3, discharging opening 4, cylinder 5, spiral separation structure 6.
Detailed description of the invention
For being more fully understood that the present invention, the present invention is further illustrated below in conjunction with the accompanying drawings, but the enforcement of the present invention
Mode does not limit so.
As shown in Figure 2.A kind of barrel configuration for dehydrator, including charging aperture 1, moisture outlet 2, hot gas inlet 3, goes out
Material mouth 4, cylinder 5, spiral separation structure 6；Cylinder 5 is obliquely installed, and is connected with rotating mechanism, the upper end that cylinder 5 tilts
It is provided with charging aperture 1 and moisture outlet 2；The lower end tilted is provided with discharging opening 4 and hot gas inlet 3；It is provided with spiral in cylinder 5 to separate
Structure 6；Spiral separation structure 6 is helical form；Spiral separation structure 6 is positioned in cylinder, in spiral partition 6 and cylinder 5
Wall compact siro spinning technology, preferably spiral partition 6 weld or by casting integrated molding with cylinder 5 inwall.Further preferably
Spiral partition 6 and cylinder 5 two ends are provided with spacing；Cylinder 5 one end to feed, and feed pipe 1 reaches in cylinder, the other end
Hot blast to be entered and discharging, a segment distance in warm-air pipe cylinder to be reached, owing to feed pipe and warm-air pipe are all fixing, no
Rotate with cylinder, and helical structure 6 rotates with cylinder, in order to avoid collision, so helical structure 6 is arranged on cylinder 5
In, set at regular intervals with cylinder 5 two ends, the preferably spacing with two ends is 0.5-1m.
It is said that in general, the screw mechanism in cylinder is to transport material, screw mechanism is to couple together with tumbler；And this
Invention spiral segmentation mechanism is and cylinder inwall compact siro spinning technology, cylinder unitary rotation, and spiral partition itself is not
Rotate.Spiral partition of the present invention, while transporting material, is separated by dry hot gas so that dry hot gas presents spiral shell
Rotation shape runs, and contrary with material direction of transfer, while extending the hot gas drying time, extends range ability, Er Qieyou
Running the most in the shape of a spiral, steam contacts with material the most fully, accelerates the drying time of material；Reduce cylinder simultaneously
Draw ratio, cylinder shortens slightly, decreases floor space.
The present invention has installed spiral separation structure additional in the cylinder of traditional single-cylinder type rotary dryer, and hot-air is along spiral shell
Rotation shape passage advances, and in the case of equal barrel lenght, extends steam residence time in cylinder, reduces gas and go out
The steam temperature of mouth, improves drying efficiency；Helical structure 6 also has the effect promoting material to advance.
The draw ratio of traditional barrel configuration is 6-12.Bigger draw ratio is used for ensureing that hot-air and material are carried out fully
Heat exchange.The draw ratio of cylinder of the present invention is 4-8 (it is for prior art takes 12 that draw ratio of the present invention takes 8)；
Actually；Ore in sand form Drying barrel dliameter 1 meter, tube length accomplishes 12 meters-16 meters, and the shortest outlet temperature of tube length is the highest, the thermal efficiency
The lowest, the longest outlet temperature of tube length is the lowest, the thermal efficiency is the highest, sees on the whole, and cylinder is the thinnest but also long, and floor space is big.Producer is
Reducing and take up an area, improve efficiency, had the design of 2 layers and 3 layers cylinder, but baking ore in sand form actual effect is bad, humidity difference ore in sand form is at folder
Motor control in Ceng is bad.The main efficacy results of the present invention is exactly in the case of the effect of same baking ore deposit, elongated cylinder, changes
Becoming short and thick, floor space is little.In the case of equal floor space, the cylinder of the present invention is thicker, and gas passage is long, and heat is handed over
Change more abundant.If to dry as standard, the major advantage of the structure of the present invention is that draw ratio is little, and floor space is little.And
In the case of equal length, real air pipeline to be grown a lot, and the temperature of outlet can be lower, and consequent heat loss is the least,
But it is also nonsensical for excessively extending pipeline, contrast so it is practically impossible to do same long cylinder.
