Abstract
The invention provides a spiral-flow dryer. An air flow guide-component is configured at the upper part of a dryer cavity. The air flow guide-component comprises a core tube and a spiral band fixed on the core tube. A spiral groove serves as a spiral air flow passage, and the rear end of the spiral air flow passage communicates with a rotational flow chamber. The edge of the upper half of the spiral band is fixed on the inner wall of the dryer cavity. A couple of mixer shafts are configured at the under part of the dryer cavity, and couples of paddle copy boards and coulters are configured on each of the mixer shafts. The invention expands the application scope of fluidized drying and is capable of breaking up and drying materials of shapes such as paste, slurry, granule, powder and filter cake inside the dryer. The invention is far superior to the common fluidized dryers in terms of volumetric drying intensity and can reduce the final moisture to an extremely low value, thereby overcoming the shortcoming that the materials for air flow drying set strict requirements for the original moisture in the materials.

The specific embodiment
See Fig. 1 to Fig. 6, present embodiment has the body 1 that is supported by frame 10, and the top of said body 1 is circular arc, and the bottom is a W shape.The top in body chamber is provided with air flow guide 2, and body chamber and the space that is in air flow guide 2 rear sides are the f of spin chamber.Air flow guide 2 comprises core pipe 2-1 and is fixed on the hurricane band 2-2 on the core pipe 2-1; Luo Gou then becomes helical form gas channel e; The rear end of helical form gas channel e communicates with the f of spin chamber, and the first half edge of air flow guide 2 through hurricane band 2-2 is fixed on the inwall in body chamber and is fixed.
The bottom in body chamber is provided with a pair of shaft 3; Two groove settings of two shafts, 3 respectively corresponding W shape bottoms; Body 1 is stretched out at the two ends of shaft 3, is provided with dynamic sealing device 9 between shaft 3 and the body 1, and shaft 3 is supported by the pair of bearing 11 that is fixed on the frame 10; Two shafts 3 are driven through transmission mechanism 8 by a motor 7 that is arranged on engine body exterior and do rotation in opposite directions, and transmission mechanism 8 is belt transmission and/or gear drive.Each shaft 3 is provided with and some blade flight 4 on blade flight 4, two shafts 3 is shifted to install, and the blade flight in the rotary course on two shafts 3 is cross-shaped.Also be provided with and blade flight 4 colter 5 at interval in the front portion of shaft 3; The setting of blade flight 4 and colter 5 is corresponding with the spiral shell ditch e of hurricane band 2-2; The quantity of blade flight 4 and colter 5 interknits with the lift angle of hurricane band 2-2, and the lift angle of hurricane band 2-2 just the quantity of blade flight 4 and colter 5 set as the case may be.The head of blade flight 4 and colter 5 stretches among the spiral shell ditch e.On the left and right inwall of body 1 bottom and the front portion of corresponding shaft 3 is provided with broken cutter 6; Said broken cutter 6 comprises motor 6-1, crushing cutter shaft 6-3 and is arranged on 3 on the crushing cutter shaft 6-3 broken cutter 6-6; Connect by shaft coupling 6-2 between the axle of motor 6-1 and the crushing cutter shaft 6-3; Shaft coupling 6-2 connects end cap 6-4 and seal cover 6-5, and crushing cutter shaft 6-6 is by the supporting of the bearing in shaft coupling 6-2 and the end cap 6-4, and broken cutter 6 is respectively rotated by driven by motor.The front bulkhead of body 1 is provided with charging aperture and dry-heat air import a, and a feed arrangement 12 is connected with above-mentioned charging aperture, and dry-heat air import a communicates with the helical form gas channel.The aft bulkhead of body 1 is provided with humid gas outlet b, and the bottom, rear end of body 1 is provided with discharging opening c, and discharging opening c is provided with drawing mechanism 13.
During the operation of this machine, material is imported body through feed arrangement, carries out fragmentation by two shafts and stirs; Under the effect that colter, blade flight and combined crushing cutter combine, material is broken, kicks up, under the effect of gas cyclone; The material of kicking up fully mixes with hot blast, and strong heat exchange takes place, by mechanical material sedimentation in hot blast of kicking up; Mix with wet stock then, kicked up, material constantly flows to discharge end under the effect of mechanical force and wind-force; Because the sectional area of the f of spin chamber is greater than the sectional area of helical form gas channel e, wind gets into the f of spin chamber from helical form gas channel e, and wind speed reduces; The sedimentation in the spin chamber of most of dust is discharged through drawing mechanism 13 at last, and humid gas is discharged by humid gas outlet b.
