Detailed description of the invention
This utility model is further illustrated below in conjunction with the drawings and specific embodiments.
The direction term being previously mentioned in this utility model, such as: upper and lower, left and right, front or rear etc., in inside referring to cylinder
Chamber, outside outer finger cylinder.Therefore, the direction term of use is used to illustrate not for limiting this utility model.
As it is shown in figure 1, a kind of pigment spray drying device, including cylinder 1 and the material storage tube 2 of bottom on top, cylinder 1 He
Material storage tube 2 sidewall uses rustless steel to make, and inwall is mirrored.Wherein the top of material storage tube 2 is cylindrically and diameter is more than cylinder 1
Diameter, bottom is coniform, and bottom is provided with discharge duct 14, and discharge duct 14 is in closed mode.
Cylinder 1 top is provided with hot-air distributor 4, is provided with scroll casing type hot blast dish (not shown), directly in hot-air distributor 4
Heat entering air therein, with the downward heat air delivery of whirlpool form.The lower section of cylinder 1 is provided with shower nozzle 31 upward
Nebulizer 3, shower nozzle 31 is located on material storage tube 2 central axis and higher than material storage tube 2.For improving the yield rate of mist projection granulating, this knot
Structure also increases in the bottom of cylinder 1 thermometer 11, and when the interior cavity temperature of cylinder 1 is higher than predetermined temperature, nebulizer 3 sprays again
Material slurry carries out mist projection granulating.
Cylinder 1 is provided with the first air inlet pipe 41 and some second air inlet pipe 42, and the first air inlet pipe 41 is for directly absorbing the external world
Air, the second the most condensed pipe of air inlet pipe 42 61 and be positioned at some second escape pipe 52 one_to_one corresponding on material storage tube 2 top even
