Description

Grain drier

Technical field

The utility model is related to grain drying devices, more particularly, to a kind of grain drier.

Background technology

It needs that processing is dried after grain harvest, reaching reduces grain moisture, kill worm's ovum, improve cereal storage quality Purpose.Heated-air drying mostly is taken to grain dry at present, is fully contacted with cereal by applying hot wind, realizes evaporation cereal water Part, the uniformity for ensureing grain dry.Traditional foodstuff drying device is gone out by the temporary storing bin on top, the drying room of lower part and bottom Hopper forms, and grain is moved by self gravitation effect in drying machine from top to bottom, and deflector, grain are arranged above drying room Food continues to flow downward from the gap between deflector, and the hot wind in hot-air channel directly blows to grain, the humid air after drying Air outlet outflow through cold air duct, the grain after heated-air drying are continued to fall into discharge chamber by lifting means again by drying room Drying is dried in secondary feeding drying machine.Using above-mentioned technical proposal, grain is dried just with indoor hot wind is dried, At least need cyclic drying 8 times is above could control the moisture in grain in safe range per storehouse grain, drying is imitated Rate is very low, high energy consumption, considerably increases the storage cost of grain.

Invention content

The utility model aim is to provide that a kind of low energy consumption, drying efficiency be high and the grain heat-drying of effectively save cost Machine.

To achieve the above object, the utility model takes following technical proposals：

Grain drier described in the utility model, including drying machine body, the drying machine body is from top to bottom successively For temporary storing bin, drying room and discharge chamber, the temporary storing bin, drying room and discharge chamber are sequentially communicated, between the lower part of the temporary storing bin Every being provided with multiple preheating blind pipes upwardly extended, it is spaced apart on the side wall of multiple preheating blind pipes and is equipped with multiple outlet air Hole, the bottom for preheating blind pipe are connected by diversion pipe with external heat air source；It is logical that air inlet has been arranged alternately in the drying room The air inlet of road and air-out passage, the air intake passage is opened on drying room front side wall, and the air outlet of the air-out passage is opened It is located on the rear wall of drying room, the side wall of air intake passage and air-out passage is orifice plate side wall, adjacent air intake passage and outlet air Drying channel is formed between channel；It is provided with air inlet in the one side wall of the discharge chamber, with the air inlet phase To the discharge chamber other side on be provided with air outlet, the allocation mechanism by power source drive is provided in discharge chamber, discharge chamber Discharge port is connected by lifting means with the feed inlet at the top of the temporary storing bin.

The utility model advantage is that comprehensively utilize preheating blind pipe, hot-air channel and the indoor air-dry performance of discharging makees jointly For grain, i.e., preliminarily dried is carried out to grain first with preheating blind pipe, be then further dried in drying room, finally utilize wind Machine substantially increases drying efficiency to the indoor grain air-drying that discharges（Drying efficiency is more than doubled）, and then carry significantly High grain heat-drying treating capacity, while energy consumption is also reduced, save drying cost.

Description of the drawings

Fig. 1 is the structural schematic diagram of the utility model.

Specific implementation mode

As shown in Figure 1, grain drier described in the utility model, including drying machine body, the drying machine body is certainly It is followed successively by temporary storing bin 1, drying room 2 and discharge chamber 3 under above, the temporary storing bin 1, drying room 2 and discharge chamber 3 are sequentially communicated, institute The lower vertical for stating temporary storing bin 1 is arranged at intervals with multiple preheating blind pipes 4 upwardly extended, prevents grain from falling into preheating blind pipe 4, It is multiple it is described preheating blind pipes 4 side walls on be spaced apart be equipped with multiple exhaust vents, preheat blind pipe 4 bottom by diversion pipe 5 with External heat air source is connected；It is alternated in the drying room 2 and is provided with air intake passage 6 and air-out passage 7, the air inlet is logical The air inlet in road 6 is opened on 2 front side wall of drying room, and the air outlet of the air-out passage 7 is opened in the rear wall of drying room 2 On, the side wall of air intake passage 6 and air-out passage 7 is orifice plate side wall, convenient for air inlet or outlet air, adjacent air intake passage 6 and outlet air Drying channel is formed between channel 7, hot wind is blowed to the grain in drying channel 8 by the side wall of air intake passage 6, the sky after exchange Gas is discharged with moisture by air-out passage 7, and the top of air intake passage 6 and air-out passage 7 is both provided with deflector 10 so that grain It is flowed into drying channel by deflector 10；Air inlet 8 is provided in the one side wall of the discharge chamber 3（For installing wind turbine Discharge pipe）, air outlet 9 is provided on 3 other side of discharge chamber opposite with the air inlet 8, it is further by wind turbine Grain is carried out to air-dry drying, improves drying efficiency；The allocation mechanism by power source drive is provided in discharge chamber 3（That is material toggling Plate）, the discharge port of discharge chamber 3 is connected by lifting means with the feed inlet at 1 top of temporary storing bin, convenient for cyclic drying again； When moisture reaches in safe range, stopping cyclic drying, grain is sent to grain storehouse by the discharge port of discharge chamber 3 through conveying equipment Interior preservation.

In use, grain is fallen downwards from the top of temporary storing bin 1 by its dead weight, extraneous heat air source by diversion pipe 5 to It preheats blind pipe 4 and hot-air is provided, hot-air blows to the grain for flowing through preheating blind pipe 4 through exhaust vent, and preliminarily dried is carried out to grain； Grain continues to fall, and the effect of 2 inner deflector of drying room flows to drying channel, and hot wind blows to stream by the side wall of air intake passage 6 The grain in drying channel, is further dried grain, and the humid air after exchange is flowed out by air-out passage 7, it is ensured that dry Effect；Grain after drying room 2 is dried is fallen into discharge chamber 3, and heat is blown into again into discharge chamber 3 by air inlet 8 Wind dries grain again, and grain flows to the discharge port of discharge chamber 3 under the action of allocation mechanism, and then boosted equipment is again It is dried in secondary entrance drying machine body, when grain moisture content control is in safe range, the grain after drying is by external defeated Mechanism is sent to be sent into storage in grain storehouse.The utility model by carrying out predrying to grain in the temporary storing bin 1, drying room 2 into Row drying drying air-dries drying in discharge chamber 3, improves drying efficiency again（Drying efficiency is more than doubled）, in turn Grain heat-drying treating capacity is substantially increased, while also reducing energy consumption, has saved drying cost.
