Description

The invention relates to agriculture, in particular to devices for drying agricultural grain products, mainly seed of grain crops, and is an improvement of the invention according to the author. St. No. 1242440.

The purpose of the invention is to reduce energy consumption.

The drawing shows a vented bunker, a general view.

The ventilated bunker consists of a loading device 1, a perforated cylindrical body 2, a conical bottom 3, a perforated I collector 4, inside which there is an air shut-off valve 5 held by a cable block 6, a main perforated cylindrical shell 7 with a conical bottom 8 installed coaxially between the body 2 and a collector 4, an additional perforated cylindrical shell 9 with a conical bottom 10 installed coaxially between the housing 2 and the shell 7, the discharge pipes Check II - 13 with flaps 14 - 16, air duct 17, translucent (made of plastic film). Shell 18, mounted with a gap in relation to (with case 2, fan 19, capable of operating as in a mode of injection - IIHH, and in the suction mode. All the elements of the bunker are placed on the frame 20 to assert perforations in the shells 7 and 9 are designed in such a way that they allow free passage of grain material from the cavity between the Ybechikas 7 and 9 (cavity A) in the between the shell 9 and the housing 2 (cavity B) and between the shell 7 and AND the collector 4 (cavity C). Unloading - The heat chutes II - 13 allow the grain product to be unloaded from the cavities B5A and B, respectively, independently of each other.

The device works as follows.

When the hopper is unloaded, the material is fed into the loading device I, with the help of which it is evenly distributed throughout the volume of the bunker, filling the cavities A, B and C "

The grain product is dried by a heat carrier (air), injected or sucked (depending on the time of day) by a fan 19 "In the daytime

Tyler tor 19 is included in suction mode. At the same time, heated air is taken from the gap between the transparent shell I8 and the body 2 (painted in matt black). Air heating is achieved through appropriate transformations and the transfer of solar radiation energy, as is the case in well-known solar collectors. The heat carrier, penetrating the grain mound in the radial direction from the housing 2 to the collector 4 (through the shells 9 and 7) “first dries the material in cavity B (the drying time is comparable with the average duration of solar blue during processing grains). When the material in the cavity B reaches the required humidity, it is discharged by opening the valve 16 in the drain 13. A moist grain product from cavity A is dumped into the emptying space through the additional shell 9, and the total grain level in the hopper decreases, allowing the valve to be lowered accordingly 5. After that, the fan 19 is switched to the pumping mode and the grain material is dried according to the usual technology, periodically unloading the dried product from the cavity B and lowering the valve lower all 5. Reducing the number ETS product causes an increase in the hopper supplying the heating medium per unit mass of material to be dried and intensifies further processing. Drying the grain in cavity B by using solar energy reduces energy consumption.
