Description
Technical field
The utility model relates to drying machine technical field, especially relates to a kind of rotary flash distillation formula drying machine.
Background technology
Heat energy is utilized to reduce a plant equipment for material moisture, for carrying out drying process to object.Drying machine makes the hygroscopic water in material (referring generally to moisture or other volatile liquid components) vaporization effusion, to obtain the solid material of regulation moisture content by heating.Dry object is the needs in order to material uses or processes further.
Flash dryer integrates novel continuous drying equipment that is dry, that pulverize, sieve, is specially adapted to the oven dry of filter cake shape, cream pasty state, sposh pasty material.Flash dryer mainly utilizes hot blast to enter bottom drying tower by air inlet with tangential direction, and spirally rise, simultaneously, material is quantitatively added in tower by feeder, and carry out sufficient heat exchange with hot blast, comparatively large comparatively wet material under the effect of stirring breaker by Mechanical Crushing, the material that water capacity is lower and granularity is less rises in the lump with swirling eddy, be delivered to separator by discharging opening and carry out gas solid separation, complete finished product collecting packing, tail gas is then emptying after dust arrester process.There is certain defect in traditional flash dryer, namely when output increases, bulky grain and not dry material are easily taken out of by swirling eddy, cause discharging defective, and grain thickness is uneven, moisture severe overweight.
Utility model content
For overcoming the problems referred to above, the utility model adopts following technical scheme:
A kind of rotary flash distillation formula drying machine, comprise Rotary drying room, the centre position, bottom of Rotary drying room is provided with agitator, agitator is provided with clasfficiator, the top of Rotary drying room is provided with discharging opening, is provided with air inlet with side lower part, is provided with charging aperture in the middle part of opposite side, be provided with screw feeder in charging aperture, the outer toroid bottom Rotary drying room is hot-air distributor.
The bottom of described Rotary drying room is cone structure.
The stirrer gear of described agitator is provided with scraper plate, and keeps gap with the inwall of Rotary drying room.
The range of speeds of described agitator is 50 ~ 500r/min.
Described clasfficiator is circular slab with holes.
The utility model has the advantages that: Spin Flash Dryer advanced technology, facility compact, simple to operate, easy to maintenance, enhance the solid heat-transfer effect of vapour, drying time is shortened dramatically, and product yield and quality improve greatly, and energy-saving effect is very remarkable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model equipment.
Detailed description of the invention
As shown in Figure 1, a kind of rotary flash distillation formula drying machine, comprise Rotary drying room 1, the centre position, bottom of Rotary drying room 1 is provided with agitator 2, and agitator 2 is provided with clasfficiator 3, and the top of Rotary drying room 1 is provided with discharging opening 4, air inlet 5 is provided with side lower part, be provided with charging aperture 6 in the middle part of opposite side, be provided with screw feeder 7 in charging aperture 6, the outer toroid bottom Rotary drying room 1 is hot-air distributor 8.
Drying principles is as follows:
According to the effect that dry run plays, the main equipment of Rotatingandflashstreamingdrier can be divided into three parts: bottom fluidization section, middle dryer section, top classification section.Each segment structure is different, and role is different.
Fluidisation section be material inlet with lower part, be inside provided with agitator 2.It can help broken high-viscosity material, and wet feed is fully contacted with heated drying air, produces maximum heat transfer coefficient.Dry-heat air enters circular passage bottom drier from tangential direction with certain speed, and at the bottom of shell, gap enters fluidisation section.Because channel cross-section reduces suddenly, kinetic energy and wind speed are increased, in device, form the rotation wind field with higher wind like this.Material, after auger conveyor enters drier, first bears the mechanical crushing of agitator, centrifugal, shear, material, by micronize, fully contacts with rotation hot blast and forms fluid bed and be fluidized under the effect of impact force.The particle surface being in fluidized state is exposed in hot blast completely, collides with each other to each other and rubs, moisture evaporation simultaneously, viscous force between particle is weakened, form dispersion, irregular motion between particle, gas-particle two-phase is fully contacted, accelerates mass transfer, diabatic process.
In fluidisation section, the cold and hot medium temperature difference is maximum, and most of moisture is evaporated in this district.Only have abundant dried particulate could be taken out of fluidisation section by hot blast.Fluidisation section belongs to high-temperature region, because fluidisation section material particles inside remains certain moisture, material can not be overheated, and dried particulate moment just departs from high-temperature region, so rotary flashing drying equipment is very applicable to heat sensitive material.
After the drying of fluidisation section, material is broken and is dried to the different spherical and irregularly shaped particles of various granularity, under the buoyancy of rotary air and the effect of radial centrifugal force, undried particle moves to wall, and the backflowization section that falls repeats fluidized drying because it has larger sinking speed; Comparatively granule upwards enters dryer section.
(2) dryer section is the space between more than reinforced spiral to clasfficiator, and now material is continuous dry at rotation wind field relaying.Comparatively granule continues upwards to enter classification section; Larger particles move upward around wall collide with clasfficiator 3 again dry, until reach dry mass requirement.
The hot blast of dryer section is after fluidisation section mass heat transfer, and wind speed reduces, and humidity increases, and ensure that dryer section is carried out smoothly under stable condition.In order to control the time of staying of material in drier, the time that should stop in drier according to air regulates air velocity, thus the granularity of finished product, output and final water content are controlled, make drier form balance between a kind of feed rate and satisfactory Dried product.The water content of spin flash dryer final products is seldom by the impact of charging moisture content fluctuation, and this is also one of advantage of this drier.
(3) classification section be comprise clasfficiator clasfficiator 3 with upper part.Clasfficiator 3 is perforate circle baffle plates, by changing diameter and the classification section height in hole, namely changing air velocity and just can control particle size and the quantity of leaving drier.Complete drying at this section, reach the material of granularity requirements and enter deduster with hot blast and trap.
