Summary of the invention
The purpose of this utility model provides a kind of drum-type drying device, and it can carry out drying materials, cooling procedure continuously, efficiently in cylinder.
The drum-type drying device that the utility model provides, comprise frame, be arranged at double-layer barrel on the frame rotationally, described double-layer barrel constitute by inner core and urceolus and inner core and urceolus between be communicated with by material spilling hole, be distributed with many group blades at the inwall of described inner core and the inwall of described urceolus, described inner core is provided with material inlet and hot blast import, described urceolus is provided with material outlet, it is characterized in that: described inner core is provided with air outlet, and described urceolus is provided with the cold wind import.
Described inner core is a cylinder, and described hot blast import and described air outlet are separately positioned on two axial opposite ends of described cylinder.
The hot blast import of described inner core connects thermal source.
The air outlet of described inner core connects exhaust duct and/or air exhausting device.
The cold wind import department of described urceolus is provided with the adjustable air door of aperture.
Described urceolus is a divergent-cone wall.
Described double-layer barrel can wind the axis rotation horizontal by an inclination angle.
The drum-type drying device that the utility model provides has following beneficial effect:
Finish the overall process of oven dry, cooling in double-layer barrel, material can directly come into operation after inner core oven dry, urceolus cooling.Have compact conformation, volume is little, easy to use, carrying, characteristic of low energy consumption.Drying course adopts the following current heating, and promptly charging aperture and heating gate are positioned at the same side of inner core, and the hot blast flow direction is identical with the Flow of Goods and Materials direction, thermal efficiency height, and material enters inner core continuously, can heat quickly and efficiently, dry.Cooling procedure adopts the cooling of cold wind adverse current, can carry out the material cooling quickly and efficiently, the drop temperature of material can be controlled by the aperture of regulating the import of urceolus cold wind simultaneously, the controllability height, can satisfy the needs of producing different drop temperature finished product material, being specially adapted to has the material of strict demand to dry to finished product material temperature.
Description of drawings
Fig. 1 is the drum-type drying schematic representation of apparatus.
Fig. 2 is the cutaway view of Fig. 1.
The specific embodiment
Shown in seeing figures.1.and.2, the drum-type drying device that the utility model provides comprises:
Frame 1.
Power set comprise known motor 2 and transmission mechanism.
Double-layer barrel is made of cylindrical shape inner core 31 and conical urceolus 32.Double-layer barrel is arranged on the frame 1 rotationally and becomes an inclination angle with horizontal plane.Cylinder bearing drives on support roller 4, by power set and rotates.The axial forward end of inner core 31 is provided with material inlet 51 and hot blast import 61, and hot blast import 61 places are provided with thermal source 62 (as burner, fluidized bed furnace, row's endless grate etc.).The axial rearward end of inner core 31 is provided with air outlet 63, and air outlet 63 connects exhaust duct, air exhausting device (not shown).The front end of urceolus 32 is that the big end of cone, rear end are the cone small end, offers material outlet 52 and cold wind import 7 at the front end of urceolus 32, and cold wind import 7 places are provided with the adjustable air door (not shown) of aperture.The rear portion of inside and outside tube is communicated with by material spilling hole 8.
At inner core 31 inwalls, be distributed with scraper blade 314, second feeding blade 315, the feed reversing blade 316 of first feeding blade 311, the first lifting blade 312, the second lifting blade 313, band sieve aperture vertically successively.At urceolus 32 inwalls, be distributed with hybrid blade 322, the 4th feeding blade 323, the discharge blade 324 of the 3rd feeding blade 321, band sieve aperture vertically successively.
The course of work of drum-type drying device is as follows: at first, the hot blast that thermal source 62 provides enters inner core 31 from hot blast import 61, and material is sent into inner core 31 by elevator (as belt feeder or other conveying equipments) by material inlet 51 simultaneously.After material enters inner core 31, because the rotation of cylinder, material is delivered to the first lifting blade 312 under the effect of first feeding blade 311, material falls after being promoted by the first lifting blade 312 again, because cylinder rotates and the installation of tilting, make material slowly run to the second lifting blade 313 and scraper blade 314 places, material is raised the back and falls from the sieve aperture of scraper blade 314, under 315 effects of second feeding blade, run to material spilling hole 8, enter urceolus 32 from material spilling hole 8, the unnecessary material that leaks down from material spilling hole 8 does not turn back to material spilling hole 8 and enters urceolus 32 under 316 effects of feed reversing blade.At above-mentioned mass transport, running, material is promoted continuously, stirs by each blade, make it in cylindrical shell, evenly to distribute and disperse, fully contact, mix with the hot blast of sending into from hot blast import 61, moisture in the material is constantly evaporated, steam is discharged from air outlet 63 and exhaust duct, realizes, high efficiency drying continuous to material thus.
After material after the quilt oven dry enters urceolus 32 from material spilling hole 8, because the rotation of cylinder, material is delivered to hybrid blade 322 under the effect of the 3rd feeding blade 321, material is raised the back and falls from the sieve aperture of hybrid blade 322, the cold wind that enters with cold wind import 7 fully mixes, the 4th feeding blade 323 pushes forward to discharge blade 324 with material simultaneously, exports from material outlet 52 under the effect of discharge blade 324.Lifting by blade, stir material is fully mixed with cold air, can be cooled to suitable temperature apace.Simultaneously, can control the drop temperature of material by the aperture of regulating the import of urceolus cold wind, to satisfy the needs of producing different drop temperature finished product material.
More than combine embodiment the utility model is illustrated, but this does not constitute restriction of the present utility model, any modification of making under same design, variation and replacement also all belong to the scope of the utility model protection.
