Description
Technical field
The utility model relates to a kind of drying equipments, and in particular to a kind of flash dryer.
Background technique
Existing flash distillation dryer is to integrate novel continuous drying equipment that is dry, crushing, be classified.Expansion drying
Drying of the device especially suitable for filter cake shape, cream paste, sposh pasty material.Hot-air tangent line enters drier bottom, is stirring
Device forms strong rotation wind field under driving, and plaster material is entered in drier by screw feeder, stirs in high speed rotation
Under the strong effect of paddle, material is impacted, rub and shearing force under the action of dispersed, block material crushes rapidly, with heat
Air comes into full contact with, is heated, dries；Above-mentioned technique can only meet more open material and be dried, if material specific gravity compared with
When big or particle crystal form is larger, agitating paddle is consistent with hot-air direction of rotation in prior art, and the shearing force for giving material is insufficient
With this kind of material is fully dispersed, continuous drying effect is not achieved, eventually leads to dry production capacity decline even material in drying
Deposition, can not be completed dry work inside device.
Utility model content
The technical problems to be solved in the utility model is to overcome the deficiencies of the prior art and provide a kind of flash dryer, it
With biggish shear ability, it is ensured that specific gravity is larger or the biggish material of particle crystal form is adequately dispersed, and is conducive to improve
Drying efficiency.
In order to solve the above technical problems, the utility model proposes technical solution are as follows: a kind of flash dryer, including successively
Air blower, heater, drying tower, cyclone separator, bag filter and the air-introduced machine of connection, drying tower are equipped with feed opening,
The bottom of drying tower is equipped with blender, and the tie point of heater and drying tower is located in drying tower bottom sides, the bottom of drying tower
Portion is equipped with scroll casing type air distributor, and blender is located in air distributor, airflow direction and blender in air distributor
Rotation direction it is opposite.
As a further improvement of the above technical scheme: position locating for the center of air distributor and the agitating shaft of blender
It sets on same straight line.
Further, clasfficiator is equipped in the top of drying tower.
Further, clasfficiator is cricoid baffle.
Further, cooling jacket is equipped in the tower wall of drying tower.
Further, blender includes agitating shaft and several blades for being evenly arranged on agitating shaft, the end of the blade
The distance between dry inner wall of tower is not more than 5cm.
Further, the middle part of drying tower, the dosing unit company of the feed opening and stepless speed regulation is arranged in feed opening
It connects.
Pure air after the utility model heats heated device blasts air inlet by air blower, is revolved with suitable speed
Enter the annular space of hothouse bottom, then enters hothouse by tangential direction, and rise in the shape of a spiral；Meanwhile material is then by can nothing
The feeder of grade speed regulation is quantitatively adding in tower.In drying tower, material and hot-air carry out abundant, efficient matter thermal conversion, quilt
Dry granular material is delivered to cyclone separator in company with hot wind together, wherein finished product collecting packing, and tail gas then further passes through
It is emptied after dust-extraction unit processing.
Scroll casing type air distributor and blender are housed in dry tower bottom, the revolving speed of blender is by adjusting external motor
Revolving speed carry out stepless speed regulation.There are two effects for blender: (1) it can drive the hot-air for entering hothouse from distributor chamber to produce
Raw high-speed rotating air-flow, and then stable fluidized-bed layer is formed, it avoids since viscous spouted alter that be stifled and generating in part is gushed
Unstable fluidization；(2) due to the multiple groups blade high speed rotation on blender, bulk materials are constantly crushed, are made outer dry interior wet
Particle constantly wrap up, remove, rubbing with the hands broken, surface is constantly updated, increase heat exchange area, flash dryer to enhance matter,
Heat exchange improves rate of drying.In addition, the blade and drying tower wall clearances on blender are smaller, can clean up in time viscous
The material on wall is tied, is denaturalized with preventing material extended stationary periods.Cooling folder is equipped with to ensure that material invariance is decomposed, in tower wall
Set, for thermal sensitivity object, section can absolutely guarantee quality.The air sparger of scroll casing type keeps the hot-air tangentially entered uniform
Twist risen by bottom annular space, reasonable annular space wind speed ensure that the good fluidized drying of material.
Constantly material is added by the dosing unit of stepless speed regulation.Meanwhile after material is crushed by the blender of bottom
It is blown afloat again by high-speed rotating hot wind, forms a kind of metastable fluosolids in hothouse.Between material and hot-air into
It goes rapidly and sufficient heat and exchange of moisture, most moisture evaporation is completed in this course.Moisture content is high, compares table
The small material particle in face settles in the drying chamber since its gravity is greater than buoyancy, constantly dry in sinking watching, moves to bottom
Broken and high-speed flow impact when portion through blade, is further crushed and is dried, its gravity is less than buoyancy, particle at this time
Begin to ramp up movement.
Material is carried secretly with swirling eddy to be risen, due to being acted on by centrifugal force, bulk, not up to moisture requirement (compares
Weight it is larger) material under the action of the centrifugal force, radius of turn increase, when its radius of turn be greater than clasfficiator radius when, divided
Grade device gear is further dried crushing in hothouse, overflows just now until meeting the requirements.Thinner grinding bodies is in the drying chamber
It carries secretly and rises with air-flow after portion is dry, since its partial size is smaller and reaches moisture requirement (i.e. specific gravity is smaller), centrifugal force is relatively
Small, radius of turn is less than clasfficiator radius, and drying tower just then is discharged with air-flow.
Compared with the prior art, the advantages of the utility model are:
1, the utility model by setting scroll casing type air distributor, and by air distributor airflow direction and stirring
The rotation direction of device is on the contrary, can increase the shear ability of blade in blender, it is ensured that specific gravity is larger or particle crystal form is larger
Material adequately dispersed, be conducive to improve drying efficiency, conducive to the drying production capacity for improving moisture or the biggish material of viscosity；
2, the utility model in drying tower by being arranged clasfficiator, it is ensured that drying effect is preferable, after can making drying
Material dispersion is higher, is conducive to improve dispersion efficiency.
