Abstract
The utility model is specifically related to a kind of improvement of downflow type fertilizer drying machine internal structure, and object is to provide the downflow type fertilizer drying machine that a kind of heat exchange efficiency is high, can shorten the fertilizer drying time.Described dryer comprises drying, is provided with parallel staggered metal fin array at the madial wall at drying middle part.Fertilizer rotates in drying, can drop on and on metal fin array, carry out with it heat exchange, thereby increase the heat transfer sheet area of drying, has improved the heat exchange efficiency of dryer; The parallel staggered mode of metal fin array can also make hot-air when by array of fins, produce turbulent flow, has strengthened the disturbance to hot-air, has strengthened hot-air flowing between fin, has improved the efficiency of heat exchange.
Description
Technical field
The utility model belongs to plant equipment field, is specifically related to the improvement of downflow type fertilizer drying machine internal structure.
Background technology
Downflow type fertilizer drying machine is a plant equipment being widely used in fertilizer production system, and its main part is the circular drying of rotation that and horizontal line are slightly inclination.Drying is by gear drive, and rotating speed is generally 2-6 rpm, and its gradient is relevant with its length, is generally 1-5 °.Fertilizer is sent into from the higher front portion of drying, contacts and carries out heat exchange with the hot-air entering from front portion, and along with the rotation of drying, fertilizer flows to compared with low drying tube rear portion and is dried and discharges under the effect of gravity.Existing downflow type fertilizer drying machine also arranges and raises plate at the rear portion of drying, thereby the various piece that can make fertilizer be evenly distributed on drying can be carried out good contacting with hot-air, has improved the heat exchange efficiency between fertilizer and hot-air.But on the whole, it is low that existing downflow type fertilizer drying machine still exists heat exchange efficiency, and drying rate is problem slowly.
Utility model content
The purpose of this utility model is to provide one and is provided with metal fin array at drying inwall, and heat exchange efficiency is high, thereby shortens the downflow type fertilizer drying machine of fertilizer drying time.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of downflow type fertilizer drying machine, comprise drying, described drying is cylinder, the madial wall at described drying middle part is provided with parallel staggered metal fin array, described metal fin array is made up of several metal fins, and described metal fin is that bottom surface is the rectangular pyramid of rectangle, and cone point points to charging aperture direction; One of them side of described metal fin is isosceles triangle, and the bottom surface of this side and metal fin is perpendicular and link together with drying.
Preferably: described metal fin adopts interference to be connected with described drying.
Preferably: described metal fin is cambered surface towards the one side of drying central axis.
Preferably: the material of described metal fin is aluminium.
The utlity model has following beneficial effect:
1. because drying madial wall is provided with metal fin array, fertilizer rotates in drying, can drop on and on metal fin array, carry out with it heat exchange, thereby increase the heat transfer sheet area of drying, has improved the heat exchange efficiency of dryer; The parallel staggered mode of metal fin array can make hot-air when by array of fins, produce turbulent flow, has strengthened the disturbance to hot-air, has strengthened hot-air flowing between fin, has improved the efficiency of heat exchange.Meanwhile, because metal fin array is positioned at drying middle part, also can not conflict mutually with the plate structure of raising at drying rear portion.
In addition,, because fertilizer can drop on metal fin array, can cause certain pressure to metal fin.Therefore, laminar metal fin is different from being generally, and adopts the metal fin with certain thickness and regular tetrapyamid shape can make fin not yielding, more durable.Because the bottom surface of rectangular pyramid is rectangle, a side is isosceles triangle, and perpendicular and link together with drying with the bottom surface of rectangular pyramid, metal fin shape is comparatively regular, and cone point points to charging aperture direction, can not produce excessive resistance along drying decline process radially to fertilizer.
2. be connected because metal fin and drying adopt interference, technique simply and more firm.
3. further preferred metal fin is cambered surface towards the one side of drying central axis, further minimizing metal fin array is the resistance along drying decline process radially to fertilizer, cambered surface has also further increased heat exchange area simultaneously, has improved the heat exchange efficiency of dryer.
Preferably aluminium as the material of metal fin make metal fin have thermal conductivity good, be easy to processing, the advantage such as with low cost.
Brief description of the drawings
Fig. 1 is the one section of madial wall that intercepts the utility model drying middle part, the schematic diagram of taper metal fin array disposed thereon;
Fig. 2 is the structural representation of the taper metal fin of the utility model preferred version.
Detailed description of the invention
A kind of downflow type fertilizer drying machine, comprises columnar drying 1, and Fig. 1 represents metal fin 2 arrays in drying 1 middle part madial wall, and metal fin 2 arrays are made up of several metal fins 2, parallel being staggered.Because metal fin 2 arrays are positioned at drying 1 middle part, can not conflict mutually with the plate structure of raising at drying 1 rear portion.In the time that drying 1 installs, in Fig. 1, the direction of advance of fertilizer and hot blast is from left to right.In the time that dryer is worked, fertilizer rotates decline in drying 1, can drop on and on metal fin 2 arrays, carry out with it heat exchange, thereby increase the heat transfer sheet area of drying 1, has improved the heat exchange efficiency of dryer; The parallel staggered mode of metal fin 2 array can make hot-air when by array of fins, produce turbulent flow, has strengthened the disturbance to hot-air, has strengthened hot-air flowing between fin, has improved the efficiency of heat exchange.In addition,, because fertilizer can drop on metal fin 2 arrays, can cause certain pressure to metal fin 2.Therefore, laminar metal fin is different from being generally, and adopts the metal fin 2 with certain thickness and regular tetrapyamid shape can make fin not yielding, more durable.Because the bottom surface of rectangular pyramid is rectangle, a side is isosceles triangle, the bottom surface of this side and rectangular pyramid is perpendicular and link together with drying 1, metal fin 2 shapes are comparatively regular, and cone point points to charging aperture direction, can not produce excessive resistance along drying 1 decline process radially to fertilizer.Meanwhile, metal fin 2 adopts interference to be connected with drying 1, and reforming technology is simple and more firm.
Preferred metal fin 2 as shown in Figure 2, because its side towards drying 1 central axis is cambered surface, thereby further reduce metal fin 2 arrays to fertilizer the resistance along drying 1 decline process radially, this cambered surface has also further increased heat exchange area simultaneously, has improved the heat exchange efficiency of dryer.
In the present embodiment, the material of preferred metal fin 2 is aluminium, have thermal conductivity good, be easy to processing, the advantage such as with low cost.But the utility model is not limited to aluminium material, in other embodiments, selected material is respectively copper and carbon steel, but is not limited to above-mentioned material, and those skilled in the art can according to circumstances replace the material with good heat conductive performance voluntarily.
