The invention relates to industrial material drying equipment, and in particular relates to a drier with a centrally combined lifting device. The drier comprises a cylinder, a riding wheel set which supports the cylinder to rotate and a driving device, wherein a universal lifting board is arranged on the inner wall of the cylinder. The drier is characterized in that the cylinder is internally provided with a plurality of supporting frames arranged at intervals, wherein each supporting frame consists of a middle circular ring and a plurality of radial rib plates, an outer ring lifting board is welded between two corresponding radial rib plates in two adjacent supporting frames, and a plurality of uniformly distributed inner ring lifting boards are welded between the middle circular rings of two adjacent supporting frames. According to the drier provided by the invention, the drying time of materials in the cylinder of the drier can be prolonged, and the heat exchange efficiency can be improved, so that the drier is mainly used for drying materials in building material, chemical and metallurgical industries.
Description
Technical field
The present invention relates to the industrial material drying plant, especially a kind of dryer with center combination raising material unit.
Background technology
Along with in industrial production for the extensive utilization of rotating drum type drying machine, how to strengthen the heat exchange efficiency of material in rotary drum drying machine, improve to dry evaporative power intensity, become one of important indicator that improves rotating drum type drying machine efficiency.Now most rotating drum type drying machine utilization, at the inboard lifting blade device that increases of dryer barrel, makes material form the material curtain, thereby increases the heat exchange efficiency of material and high-temperature flue gas on the market, reaches to improve to dry evaporative power intensity purpose.Although form the material curtain, can effectively improve the heat exchange efficiency of material within the unit interval, the time when material is in the high strength heat exchange is still very short.Material, in drying machine barrel, is kicked up until the process of falling is the heat exchange best period by lifting blade.If material falls, be deposited in the drier body bottom, only have the material of lower surface directly to carry out heat exchange, heat exchanger effectiveness is low.The our factory of take is produced Φ 3.6*30m dryer and is example, and rotating speed is that n=4.6 turns/min.
Set up Mathematical Modeling, material is per minute to be kicked up until t=n* average time (2h/g) fallen by lifting blade
1/2I
h=0.75*D Ⅱ
N: dryer rotating speed 4.6 turns/min
H: material is kicked up by lifting blade until the average height of falling
D: dryer diameter
G: acceleration of gravity 9.8m/s
2
In the I formula, bring h=3.6*0.75=2.7m into, can obtain t=3.4s/min; Hence one can see that, and best heat exchange is only material period in drying machine barrel 5% of the time of staying.
By I, the II formula is as can be known, and optimal heat is relevant with dryer diameter and rotating speed swap time, and the diameter rotating speed is larger, and optimal heat is longer swap time, but the infinitely increase of dryer diameter and rotating speed, they all are limited by technological design.
Therefore existing dryer is subjected to structural limitations (only having single barrel lifting blade), and the raising of its heat exchange efficiency has been subject to restriction.
Summary of the invention
Purpose 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, and improves a kind of dryer with center combination raising material unit.
Concrete scheme of the present invention is: improve for existing cylindrical dryer, it has support roller group and the drive unit of cylindrical shell, supporting cylinder rotation, at cylinder inboard wall, be provided with general lifting blade, it is characterized in that: some spaced apart bracing frames are housed in cylindrical shell, each bracing frame is comprised of middle annulus and some radially gussets, the corresponding outer ring lifting blade that radially has been welded between gusset in twos in adjacent two bracing frames, some uniform inner ring lifting blades are welded between the middle annulus of adjacent two bracing frames.
Described in the present invention in twos the inner ring lifting blade on bracing frame with outer ring lifting blade radical, equate, and both angles that stagger are arranged.
In the present invention, be provided with interior annulus on each bracing frame, in the interior annulus of all bracing frames, be coated with a four-bladed vane and connect all bracing frames.
The cone large bamboo hat with a conical crown and broad brim that has been welded on the interior annulus of each bracing frame in the present invention, all cone large bamboo hats with a conical crown and broad brim top towards the cylindrical shell feed end.
Radial rib plate number in the present invention in all bracing frames equates and is evenly arranged, and the radially gusset in adjacent two bracing frames is that positioned opposite or the certain angle that staggers are 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 of being 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 again the cylinder body bottom deposition.Its heat-exchange time will be 1 ~ 2 times of common 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, further strengthen drying efficiency.
3. in connecting, the bracing frame of center, outer ring lifting blade can also adopt the angle that staggers to arrange, more is conducive to material and forms even material curtain, increases drying efficiency.
4. the deposition material of drier body bottom is divided into three levels by inside and outside circle lifting blade, the heat exchange area while having increased the material precipitation.
The present invention designs ingenious, has increased the time of the optimal heat exchanging form of material in cylinder, has greatly improved the heat exchange efficiency of dryer.
