Description
Technical field
The present invention relates to a kind of grain fast-drying device, belong to agricultural drying mechanical field.
Background technology
China is large agricultural country, and country produces to agricultural machinery and supported with application big country.The enterprises such as grain purchases, storage, processing and agricultural cooperatives, home farm largely use crop dryer, and
To the quality requirements more and more higher of crop dryer machinery.The collection of grain etc. after drying efficiency, drying of traditional foodstuff drying device is perfect not enough, and grain is short with the time of contact of hot-air, dries not thorough, it is necessary to repeatedly be dried, and increases the working strength of peasant, is unfavorable for the popularization of agricultural equipment.China is global maximum grain-production state and country of consumption, according to statistics, every year because of climate reasons, grain have little time to dry or
Not up to safe moisture storage standard and cause the grain for going mouldy, germinateing to be up to 5% or so, if the 60709.9 ten thousand tons of calculating of national total output of grains in 2014 announced by State Statistics Bureau, eaten equivalent to more than 3,000 ten thousand ton-grain of annual loss.At present, the method for grain heat-drying is usually to rely on thermal source, and the grain for needing is shed in the presence of gravity or machinery, allows moisture slowly to be distributed in the presence of conduction, convection current and radiation, so as to reach the purpose of grain heat-drying；But, its furnace drying method is more complicated, equipment power consumption is high,
Automatization level is low, investment is big.
Existing roller dryer is mainly made up of hot-blast stove, Drying, blower fan, conveying equipment etc., and its simple structure, easy to maintenance, cost are relatively low, but because tables of equipment one, drying effect is poor, and the drying effect of especially relatively large to humidity grain is not
Ideal, yield is relatively low；High-efficient simple, the drying machinery of energy-conserving and environment-protective and the furnace drying method used there is presently no suitable farm machine test, big farming household and village's group.
The content of the invention
It is an object of the invention to：For above-mentioned problem, there is provided a kind of grain fast-drying device, using double-deck casing, dry from inside to outside, with more preferable drying effect using hot-air from top to bottom；Discharge chamber is provided between the casing of two-layer, the effect with insulation, with more preferable drying effect, present apparatus simple structure is easy to use, can realize the miniaturization of drying plant, is conducive to the popularization of equipment.
The technical solution adopted by the present invention is as follows：
The invention discloses a kind of grain fast-drying device, it is characterised in that it includes by casing and air heater, casing includes internal box and outer case, discharge chamber is provided between internal box and outer case, some through holes are provided with internal box for connecting the inner side and outer side of internal box；Air heater is connected to the air inlet at the top of internal box by pipeline；Drying pipe is set in internal box, through hole is provided with drying pipe, drying pipe upper end connection internal box top, bottom extend to internal box bottom；Blast pipe is provided with outer case.
Further, dividing plate is provided with the discharge chamber, discharge chamber is divided into multilayer by dividing plate.
Further, it is respectively arranged with exhaust outlet in outer case corresponding with each layer of discharge chamber.
Further, air blower is provided with the top of the casing, the air inlet of the air blower is connected with air heater, air outlet is connected with the air inlet of internal box.
Further, the drying pipe is in Pear-Shaped, includes that the distance between multiple annular protrusions, two neighboring annular protrusion are 20-30cm on the drying pipe of Pear-Shaped.
Further, also including the clarifier-tank being filled with water, the exhaust outlet is stretched under the liquid level of clarifier-tank.
Further, the drying pipe of two or more Pear-Shaped is provided with the casing, is connected on the air inlet of casing after the drying pipe top parallel connection of two or more Pear-Shaped.
Further, it is provided with the first filter on the lateral wall or madial wall of the drying pipe.
In sum, by adopting the above-described technical solution, the beneficial effects of the invention are as follows：
1st, casing uses interior outer double-layer structure, the mechanism of its internal box ensure that casing is uniform and discharge moisture to surrounding, make the discharge of moisture more uniform, its is reasonable in design, it is easy to use, make grain in drying, the humid air with moisture can be discharged uniformly to surrounding, the moisture inside grain is set fully to spread, the grain quality after drying is higher；Its discharge chamber also has the function of insulation, greatly shortens drying time, makes drying effect more preferably, and grain heat-drying yield is increased；The structure of three layers of the upper, middle and lower of discharge chamber ensure that, separate three layers, then by the cooperation with the magnetic valve for being located at each layer, and then ensure dry uniform, the lift grain dry mass of the grain of three layers of the upper, middle and lower of casing.
2nd, the present apparatus is dried by the way of air draft under upper ventilation, the speed of the efficiency of drying can be increased, the uniformity of grain heat-drying is ensure that simultaneously, the grain dried by the device has more long Storage period, can not only ensure that grain is quickly effectively dried, additionally it is possible to mitigate the work load of peasant；In suspended state, the moisture inside grain is set fully to spread, the grain quality after drying is higher,
Greatly reduce percent cracked rice and percentage of damage.
