Description of drawings
Fig. 1 is the structural representation of the utility model embodiment,
Among the figure: 1. drying machine tower body, 11. dryer section, 12. fluidisation section cylindrical shells, 121. cylindrical shells refrigeration chuck, 2. frustum, 21. frustum refrigeration chuck, 3. annular space, 4. heat-insulation layer, 41. heat-insulation layers refrigeration chuck, 5. fluidisation section shell, 51. air inlet, 52. annular space windows, 6. solid particle drain hole, 61. valves.
The specific embodiment
Below in conjunction with drawings and Examples, further set forth the utility model.Should be understood that these embodiment only are used for explanation the utility model and are not used in the scope of the present utility model that limits.Should be understood that in addition those skilled in the art can make various changes or modifications the utility model after the content of having read the utility model instruction, these equivalent form of values fall within the application's appended claims limited range equally.
As shown in Figure 1, Whirlwind flash drier, comprise drying machine tower body 1, the bottom of drying machine tower body 1 is provided with frustum 2, drying machine tower body 1 comprises the fluidisation section and is positioned at the dryer section 11 on fluidisation section top, the outer wall of fluidisation section cylindrical shell 12 is provided with fluidisation section shell 5, between fluidisation section cylindrical shell 12 outer walls and fluidisation section shell 5, be provided with successively cylindrical shell refrigeration chuck 121 and heat-insulation layer 4, the inwall of the inner chamber of frustum 2 and heat-insulation layer 4 is respectively equipped with frustum refrigeration chuck 21 and heat-insulation layer refrigeration chuck 41, fluidisation section shell 5 is provided with the air inlet 51 that passes heat-insulation layer 4 and heat-insulation layer refrigeration chuck 41, form annular space 3 between heat-insulation layer refrigeration chuck 41 and fluidisation section cylindrical shell 12 bottoms, the below of fluidisation section is provided with a solid particle drain hole 6, and solid particle drain hole 6 is provided with valve 61.
Circumferentially be provided with 3 annular space windows 52 that are used for observing annular space on the fluidisation section shell 5.Annular space window 52 runs through fluidisation section shell 5, heat-insulation layer 4 and heat-insulation layer refrigeration chuck 41.
Hot-air is entered the annular space 3 of hothouse bottom with tangential direction by air inlet 51; rise through frustum 2 helical forms; simultaneously; after the charging aperture at material drying machine tower body 1 middle part enters Whirlwind flash drier; granule in the material is with upper rotational gas flow attitude floating in the shape of a spiral; bulky grain sinks because having larger sinking speed; in the sinking process; adhesion weakens between particle owing to the hygroscopic water evaporation makes; thermal current with rotation after stirring is smashed meets; form two alternate larger relative velocities; because air-flow produces strong shearing to solid particle; blow floating; rotation turbulence effect; impel heat and mass boundary layer attenuate; reduce the resistance of heat and mass, increased the alternate heat and mass transfer coefficient of gas-solid, meanwhile; because particle mutually collides with rubbing and stir fragmentation and makes the material micronize, thereby makes unbound water flash distillation in the material.Air-flow enters the back taper flowing space through annular space, actual internal area changes from small to big, and makes air velocity gradually reduction from bottom to top, and the particle of different-grain diameter suspends at frustum 2 interior different height respectively, increase the time of staying of particle, thereby be conducive to the moisture vaporization.Owing to existing the poor and mass transfer temperature difference of larger heat transfer at the hot-wind inlet place, under it promotes, most unbound waters are vaporized in the gas phase in the material, thereby are pulverizing the very high rate of drying of the indoor formation of expansion drying, make material rapid draing and along with air-flow leaves drying machine tower body 1.
Simultaneously, be filled with cold-producing medium in cylindrical shell refrigeration chuck 121, frustum refrigeration chuck 21 and the heat-insulation layer refrigeration chuck 41, cold-producing medium reduces the temperature of fluidisation section cylindrical shell 12, frustum 2 and heat-insulation layer 4, material can because of overheated and lumpd by coking, can not make heat sensitive material be difficult for carbonization, improve the quality of products.In carrying out dry run, can observe at any time material situation in the annular space through annular space window 52, when in the annular space hard particles when more, can in time open valve 61, allow the particle of piling up drain via solid particle drain hole 6, prevent from stopping up annular space 3.
