Description
Technical field
The present invention relates to industrial material drying plant, especially a kind of dryer with center combination raising material unit.
Background technology
Along with the extensive utilization for rotating drum type drying machine in industrial production, how to strengthen the heat exchange efficiency of material in rotary drum drying machine, improve and dry evaporative power intensity, become one of important indicator improving rotating drum type drying machine efficiency.Now most rotating drum type drying machine utilization increases lifting blade device inside dryer barrel on the market, makes material form material curtain, thus increases the heat exchange efficiency of material and high-temperature flue gas, reaches and improves oven dry evaporative power intensity object.Although form material curtain effectively can improve the heat exchange efficiency of material within the unit interval, time when material is in high strength heat exchange is still very short.Material, in oven dry machine barrel, is kicked up by lifting blade until the process fallen is heat exchange best period.Be deposited in bottom drier body if material falls, then only have the material of lower surface directly can carry out heat exchange, heat exchanger effectiveness is low.Produce Φ 3.6*30m dryer for our factory, rotating speed is that n=4.6 turns/min.
Founding mathematical models, material is per minute to be kicked up by lifting blade until t=n* average time (2h/g) that falls
1/2i
h=0.75*DⅡ
N: dryer rotating speed 4.6 turns/min
H: material is kicked up by lifting blade until the average height fallen
D: dryer diameter
G: acceleration of gravity 9.8m/s
2
In I formula, bring h=3.6*0.75=2.7m into, can t=3.4s/min be obtained; It can thus be appreciated that best heat exchange to be only material period drying 5% of the time of staying in machine barrel.
By I, II formula is known, and optimal heat is relevant with rotating speed with dryer diameter for swap time, and diameter rotating speed is larger, and optimal heat is longer for swap time, but dryer diameter and rotating speed can not infinitely increase, and they are all limited by technological design.
Therefore existing dryer is by structure restriction (only having single barrel lifting blade), and the raising of its heat exchange efficiency receives restriction.
Summary of the invention
Object of the present invention is exactly the design of Gonna breakthrough tradition cartridge type drying machine structure, solves the problem that its heat exchange efficiency is difficult to improve, improves a kind of dryer with center combination raising material unit.
Concrete scheme of the present invention is: improve for existing cylindrical dryer, the support roller group that it has cylindrical shell, supporting cylinder rotates and drive unit, general lifting blade is provided with at cylinder inboard wall, it is characterized in that: at cylindrical shell built with some spaced apart bracing frames, each bracing frame is made up of middle annulus and some radial gussets, be welded between radial gusset corresponding between two in adjacent two bracing frames outer ring lifting blade, and be welded some uniform inner ring lifting blades between the middle annulus of adjacent two bracing frames.
Inner ring lifting blade described in the present invention between two on bracing frame is equal with outer ring lifting blade radical, and both offset angular are arranged.
On each bracing frame, be provided with interior annulus in the present invention, in all bracing frames, in annulus, be coated with a four-bladed vane connect all bracing frames.
In each bracing frame, annulus has been welded in the present invention cone large bamboo hat with a conical crown and broad brim, all cone large bamboo hats with a conical crown and broad brim top towards cylindrical shell feed end.
Radial rib plate number in the present invention in all bracing frames is equal and be evenly arranged, and the radial gusset in adjacent two bracing frames is that the positioned opposite or certain angle that staggers is arranged one by one.
The section configuration of the lifting blade of outer ring described in the present invention and inner ring lifting blade can be herringbone or cross or M shape or X-shaped.
The present invention has the following advantages:
1. the material kicked up by common lifting blade 2 does not directly drop to cylinder body bottom deposition, but after first dropping on center, outer ring lifting blade 3 and slightly stopping, then drop on inner ring lifting blade 4, finally drop to cylinder body bottom deposition again.Its heat-exchange time will be 1 ~ 2 times of general dryer.
2., in, outer ring lifting blade and central cross plate also can be used as heat transferring medium and carry out heat exchange with the material fallen thereon, strengthen drying efficiency further.
3. in connecting, the bracing frame of center, outer ring lifting blade can also adopt offset angular to arrange, is more conducive to material shape and uniformly expects curtain, increases drying efficiency.
4. the deposition material bottom drier body is divided into three levels by inside and outside circle lifting blade, adds heat exchange area during material precipitation.
The present invention designs ingenious, adds the time of the optimal heat exchanging form of material in cylinder, substantially increases the heat exchange efficiency of dryer.
