Abstract

A grain dryer provided with a semi-angular box is mainly used for drying grains. Grains in a common angular box dryer approaching the lateral wall of the dryer contact little thermal medium during downward operation, have poor heat exchange effect, and have water-content difference from grains in the middle of the dryer after drying, thereby affecting storage of the grains. An angular box is arranged inside the dryer, and further, a semi-angular box is designed on a lateral wall of the dryer and fixed on the wall of the dryer via bolts, thereby improving fluidity of grains in the dryer and leading water content of corns to be more uniform after drying. The grain dryer is not only adaptable to drying corns, but also used for drying grains such as barley, wheat, rape seed and the like.

Description

Be provided with the grain drier of half-angle shape box

Technical field

The utility model belongs to the grain drying technical field, is a kind of grain drier that is provided with half-angle shape box that is used for grain heat-drying.

Background technology

The grain drier of each manufacturer's manufacturing adopts a lot of of horn shape box at present, existing downflow type grain drier, reverse-flow grain drier, mixed-flow grain drier, also has concurrent-countercurrent formula grain drier, its widely used horn shape box is pentagonal, this kind horn shape box is simple in structure, make easily, easy for installation.But also there is certain problem.Be near the grain of drying machine sidewall, few at the thermal medium of downward contact in service, the heat exchange weak effect, there is moisture difference in the grain middle with drying machine after drying, influence the preservation of grain.

The utility model content

The utility model is transformed on the basis of original horn shape box grain drier, and not only design has the horn shape box in drying machine, and designs half-angle shape box on the drying machine sidewall.Half-angle shape box adopts and is bolted on the drying machine sidewall.Improved the flowability of grain, made dried corn moisture more even at drying machine.

Main feature of the present utility model is as follows:

1 adopts horn shape box structure, the mixed flow form, and existing adverse current when grain conducts heat with hot blast (cold wind) in drying machine has following current again, and wind speed is even, the heat transfer efficiency height,

2 adopt the stepless speed regulation discharge mechanism, according to the difference of material moisture, can control the oven dry activity duration by adjusting discharge velocity, thereby make each material reach safe moisture content requirement.

3 machines adopt the drying process of drying, tempering, drying, cooling in dry run, thus make after the cereal drying moisture evenly.

4 easy for installation, adjust easy, easy to maintenance.

5 drying processes are simple, easy to operate, noise is low, environment is good.

Fig. 3 is the half-angle shape box block diagram in the utility model;

Fig. 4 is the right view of Fig. 3;

Fig. 5 is the left view of Fig. 3.

1 is grain-entering mouth among the figure, and 2 is grain storage section, and 3 are exhaust horn shape box, 4 is half-angle shape box, and 5 are the exhaust shutter, and 6 is last dryer section, 7 is delay section, and 8 are air inlet horn shape box, and 9 are following dryer section, 10 is cooling section, and 11 is grain discharging section, and 12 are row's grain mouth, 13 is dry inlet air plenum, 14 is exhaust chamber, and 15 are the cooling inlet plenum

The specific embodiment

The utility model adopts building block system split assembling (tower shape) structure, the main bolt that adopts connects, king-tower laterally outwards is followed successively by dry inlet air plenum 13, dryer section (upper and lower), exhaust chamber 14 3 parts at drying nest from the centre, in height branch has grain-entering mouth 1, grain storage section 2, last dryer section 6, delay section 7, following dryer section 9, cooling section 10, discharge zone 11 and row's grain mouth 12 again, each section is connected with corresponding subsidiary engine again, finishes drying, cooling, the discharge operation of material.Thereby be met the finished product of water content requirement.

Half-angle shape box adopts on the sidewall that is bolted to dry joint.Wet stock enters the grain storage section 2 of drying machine after screening, along with discharge, material descends gradually and enters dryer section 6, carries out mass-and heat-transfer that material is heated is dry while at this moment send into the drying medium of regulation and material by air-heater, along with the carrying out of dry run, moisture content constantly descends, behind the water balance through making thermal material after the tempering, proceed drying again, obtain desired product, material after the oven dry enters cooling section 10, is discharged by discharge mechanism by the cold wind cooling back that air-cooler is sent into.

Introduce the hot blast chamber of sending into drying machine through the air of heating by air-heater from hot-blast stove (heat exchanger), in the time of by the grain layer and after material carries out mass-and heat-transfer, become moisture and enter out air compartment and enter atmosphere by shutter.

Cold air is sent into the cold air chamber of drying machine by air-cooler, in the time of through the grain layer material is cooled off, and enters out air compartment then, enters atmosphere by shutter.

[0018] the utility model not only is applicable to corn-drying, also can be used for the oven dry operation of cereal such as barley, wheat, rapeseed.

Claims

1. a grain drier that is provided with half-angle shape box is used for grain drying.It is characterized in that: the horn shape box is not only arranged in drying machine, and on the drying machine sidewall, design half-angle shape box.

2. the grain drier that is provided with half-angle shape box according to claim 1 is characterized in that: half-angle shape box adopts and is bolted on the drying machine sidewall.
