Description
Technical field
The present invention relates to crop dryer technical field more particularly to a kind of Mixed-Flow Grain Dryers.
Background technique
The various cereal agriculturally harvested are intended to carry out removal moisture drying processing, and the purpose of removal moisture drying processing is to reduce
Its internal moisture reduces water content in cereal, reduce water content on the one hand can reduce cereal voluntarily respiration and disappear
Energy consumption；On the other hand avoid moisture content is excessively high from leading to grain germination, mildew.Large-scale grain dry master in the prior art
Crop dryer is used, has the advantages that dewatering time is short, it is high-efficient to be dried, the matter of cereal storage has been effectively ensured
Amount, reduces the probability of Moldy Foodstuff, germination, and to ensuring that it is vital that grain security plays the role of, cereal is dry in recent years
Dry machine is quickly grown, increasingly by the welcome of users.
The baking zone of crop dryer, carries hot-air channel and cereal falls the double action in channel, in baking zone, under
The cereal-granules fallen are mixed with the hot wind of flowing, are collided, and are taken away the moisture in cereal-granules using hot wind, are reached the mesh of drying
's.
The dry section of crop dryer generally uses cross-flow type structure in the prior art.There is several be vertically arranged in dry section
And cereal channel parallel to each other.Cereal channel two sides are perforation sieve plate, have uniformly been covered on sieve plate and have been less than cereal-granules geometry
The through-hole of size.Hot-air channel and cooling wind channel have been alternatively arranged between cereal channel.Cereal in cereal channel it is vertical from
Upper slowly flowing downwards, hot wind is out of hot-air channel horizontal through sieve plate, release heat and after absorbing grain moisture, into cooling
Air duct.According to the difference of dried grain kind, the hot blast temperature in hot-air channel is between 45 DEG C -160 DEG C, cooling wind channel
Interior air temperature drops to 8 DEG C higher than environment temperature hereinafter, wind-warm syndrome difference in two sides is larger.Even low temperature drying thermal sensitivity paddy
When, two sides wind-warm syndrome differs also at 15 DEG C or more.Since cereal channel temperature difference differs larger, cause close to hot-air channel
Cereal absorption heat is more, and the cereal absorption heat close to cold side is few, causes the grain dry speed close to hot-air channel side fast,
Grain dry speed close to cold side is slow, so that rate of drying is inconsistent, unevenly, drying is not thorough enough.In view of crossing current
How the disadvantages mentioned above of formula crop dryer provides the mixed-flow paddy that a kind of structure is simple, drying is thorough, efficiency of energy utilization is high
Object drying machine is the technical problem that those skilled in the art need to solve.
Summary of the invention
For above-mentioned shortcoming in the prior art, simple, dry thorough, energy benefit that the present invention provides a kind of structures
With high-efficient Mixed-Flow Grain Dryers.
The present invention using following technical scheme in order to solve the above technical problems, realized:
Design a kind of Mixed-Flow Grain Dryers, including pedestal, the drying machine main body being mounted on the base, for promoted to
The grain elevator of dried grain, the drying machine main body are vertically arranged, and from top to bottom successively include grain storage section, tempering
Section, mixed flow drying section and grain discharging section, the mixed flow drying section are made of shell, inner thermal insulating layer, horn shape box；The shell packet
The outside of inner thermal insulating layer is overlayed on, and is closed cavity between the shell and inner thermal insulating layer, is equipped with air inlet in the cavity
Pipe, the horn shape box both ends pass through inner thermal insulating layer and are arranged in cavity, and described horn shape box one end is connected with air inlet pipe, institute
Part of the horn shape box stated inside inner thermal insulating layer is equipped with several through-holes, and horn shape box described in adjacent two layers is staggered, and
The horn shape box and air inlet pipe connecting portion are additionally provided with switch valve；The air inlet pipe passes through shell and is connected with burner, institute
The burner stated is connected with air blower.
Preferably, the upper end of the drying machine main body, which is additionally provided with, sheds disk.
Preferably, the horn shape box cross sectional shape is triangular structure, and a line of triangular structure is horizontal positioned.
Preferably, the upper end of the cavity is connect with exhaust pipe.
A kind of Mixed-Flow Grain Dryers proposed by the present invention, beneficial effect are:
(1) present system in inner thermal insulating layer in be equipped with the horn shape boxes of several layers, the horn shape boxes of adjacent two layers is staggeredly set
It sets, cereal successively encounters horn shape box during decline and just changes motion profile, increases move distance, slows down lower reduction of speed
Degree, and then drying time is increased, so that grain dry processing is more thorough；And pass through opening for each layer of switch valve of control
The trend that can control inner thermal insulating layer internal gas flow is closed, the drying mode of fair current, crossing current and adverse current is obtained, and then it is dry to reach mixed flow
The effect of dry processing；
(2) the mixed flow drying section of present system is equipped with shell and inner thermal insulating layer, and the hot-air being discharged from horn shape box is discharged into
Into the cavity between shell and inner thermal insulating layer, reaches the beneficial effect kept the temperature to inner thermal insulating layer, effectively reduce energy
Scatter and disappear, and then improve energy utilization efficiency, reduce drying cost；
(3) present system structure is simple, and grain dry is thorough, and technical principle is mature, is with a wide range of applications.
