GAS DISTRIBUTION DEVICE IN SHAFT GRAIN DRYER Russian patent published in 2017 - IPC F26B17/12 

FIELD: agriculture; machine building.

SUBSTANCE: invention relates to agricultural machines building, specifically to fodder, seed grain drying machines and can be used at grain threshing-floors and procuring enterprises. Present invention can be used for various technical crops seeds drying, as well as various loose materials in other branches of industry. Gas distribution device in shaft grain dryer includes drying, feeding and discharge chambers, as well as supply and discharge conduits or half-conduits arranged in drying chamber in alternating lines, supply conduits are connected with feeding chamber by open end surface, and discharge are with discharge, located on drying chamber opposite side, device components dimensions are determined depending on each conduit inlet channel “b” width by following relations: distance between conduits in each horizontal line: b1=(1.9–2.1)b, maximum conduit width b2=(1.6–1.7)b, distance between conduits by shaft height: b3=(1.85–2.05)b, conduit upper part height b4=(1.5–1.6)b, conduit lower part height b5=(0.45-0.48)b, according to invention conduit length b6 is made from ratio b6=(18–21)b. Gas distribution by proposed device is implemented as follows.

EFFECT: increasing efficiency, grain dryer dimensions reduction by shaft height reducing, reduction of bucket conveyors height, increasing of shaft grain dryer stability, reducing transportation costs, as well as installation costs and result is reduction of product total cost.
