It is consistent with 1 rotation direction of outer barrel that 46 dog-ears raise direction.
It should be pointed out that the two neighboring shovelling plate 35 is spaced 90 degree, it is uniform between the two neighboring shovelling plate 35
It is distributed two shovelling plates 24.
The utility model is alternately changed by the dog-ear of shovelling plate and arranged for interval, is conducive to disperse materials curtain, improve material with
The contact probability of heat source.
Further for, can also consider in the present invention, the drum drier of the compound shovelling plate of band into
Expect that end is equipped with feed inlet 1a and hot wind inlet 1b, the discharge end of the drum drier of the compound shovelling plate of band be equipped with discharge port 1c and
Hot-blast outlet 1d.Material is consistent with hot wind direction.
It should be pointed out that the outer barrel 1 is obliquely installed using the high discharge end of feed end is low, the outer barrel 1 with it is described
The central axes of inner cylinder 3 overlap.
The utility model material is consistent with hot wind direction, wet granular can be promoted to contact high temperature heat source at first, is conducive to increase
Particle intensity early period, and then reduce Particle attrition phenomenon.
As an example, in the present invention, wet granular material enters one area of drum drier by feed inlet 1a, and an area is
There is no a smooth rollers of shovelling plate, it is small that wet granular material raises height, subtract in the case where granule strength is not high it is less granular beat,
Reduce broken rate of grinding ball.Material squeezes plasticity by rubbing and becomes smaller, and promotes rounded grain surface smooth, the moisture in particle ball is extruded to
Particle surface carries out heat exchange with the high-temperature hot-air that hot wind inlet 1b enters, is oven-dried hot wind and takes away, prevents moisture lock in ball
It is interior, tentatively improve granule strength by this process.Material enters 2nd area, and two area's outer barrels, 1 inner wall border is evenly distributed with shovelling plate 1, copies
Plate 1 is the angle steel of back-off, plays the tipping effect of very little to material with the rotation of roller；Smooth inner cylinder 3, pressure is arranged in this region
The contracting hot-air flowing space improves material and hot wind contacting efficiency, further cured granulate.Material enters 3rd area, three area's outer barrels 1
Shovelling plate 24 and shovelling plate 35 is arranged in inner wall circumferential interval, and shovelling plate 24 is the lifting blade in 90 °, and shovelling plate 35 is the lifting in 145 °
Plate.Three area's inner cylinders, 3 outer wall border is evenly distributed with shovelling plate 46, and shovelling plate 46 is the lifting blade in 145 °.Pass through 1 compound shovelling plate of inner/outer tube
Setting increases lifting amount, increases material in the residence time of 3 outer wall of inner cylinder, improves the contact area of material and heat source, make water
Divide flash baking, while reducing material curtain height, reduces broken ball phenomenon caused by particle is beaten.
The present invention is suitable for siliceous fertilizer, calcium silicate fertilizer, silicon-calcium-potafertilizer fertilizer, silico-calcium potassic-magnesian fertilizer, potash-lime fertilizer, potassium silicon fertilizer, potassium calcium silicate fertilizer etc.
Drying course after mineral fertilizer (soil conditioner) and its derived product granulation.By 1 subregion of inside and outside cylinder, different type is set
Shovelling plate can effectively improve the contact area of material and hot wind, barrel, increase dry materials efficiency, reduce heat consumption, help to save
About production cost；Material curtain height is reduced simultaneously, reduces material drop, reduces the breakage rate of round granular material, is improved finished product and is closed
Lattice rate.
In conclusion the utility model can provide a kind of increase drying area, improve heat exchanger effectiveness, it is high to reduce material curtain
Spend, reduce the drum drier of the compound shovelling plate of band of Particle attrition rate.
The utility model is described in detail in above example, but the content is only the preferable reality of the utility model
Example is applied, should not be considered as limiting the scope of the present invention.Equalization made according to the scope of application of this utility model
Variation and improvement etc., should all still belong within the patent covering scope of the utility model.
