Description

The subject of the invention is a mobile carriage-type grain dryer, operating in two-step drying mode on a mixture of racing gases with air, with the reduction of open bottom boxes for supplying the vehicle with a tenon carrier.

A feature of the described grain dryer is that, in order to achieve uniform heating of the grain by blowing it in a thin layer, the receiving boxes of several upper horizontal rows in the drying zones are located between the pairs of outlet ducts and in the vertical plane through the row.

In the drawing, the dryer is shown in three projections. The grain dryer is installed in a railroad car, it has two vertical shafts, a fire chamber and a mixing chamber for preparing a heat carrier, a fan with an electric motor for it and a power station consisting of an internal combustion engine and a generator. The car is equipped with an electric motor with a gearbox dl. his move. Zernosushchilka is equipped with portable conveyors and auto feeders with efficient electric motors for organizing its continuous operation in accordance with local conditions.

The feeding of grain for drying is carried out through the side bin J adjacent to the mink 2 feeding the upper scraper conveyor 3. To reduce the size of the grain dryer in height and to more efficiently use the bins of the drying shafts; 1ad and below them are conveyors 5 and 19 with horizontal sprockets, carrying and driving chains, on the lower links of which are attached scrapers. Conveyors 3 and 19 serve up both scales of the grain dryer, installed vertically in the U / C part of the agon, sequentially loading these mines with grain.

Each drying shaft is divided into three zones: cooling, drying 5 and 6 liters of super dry bunker 7. In zone 5, the temperature of 100-110 is maintained when drying food grains. in zone 6, the temperature is about 150-170 °. The flue gases from the furnace 8 are diluted in the required proportion with air in the mixing chambers 9. of which the fan 10 is injected, blown, and the coolant

in and out of the mines, supply and discharge chambers 11, transverse to them, open at the bottom and located in horizontal planes. The mixture of flue gases with air enters the open ends of the ducts from the side of the distribution chamber and penetrates the grain layers located in zones 5 and 5. Work BB: The gases go into the atmosphere. To cool the grain in zone 4, air is sucked in by fan 10, into the duct from the atmosphere, penetrating the grain layers, and thrown out.

Chambers located between the walls of the car and the side walls of the mines and between the two mines are intended for the supply and removal of coolant into the duct zones of the dryer shafts. In the lower part of the shaft there is an exhaust mechanism / 2, consisting of trays and a movable carriage, and is designed to discharge dried and cooled grain to the conveyor 19, which moves the grain to the chute 13.

In zone 6 of each mine, the receiving boxes forcing the coolant are located between the pairs of by-pass suction coolant boxes. Such an arrangement of the boxes of horizontal rows of drying zones Z.Akht leads to the horizontal direction of the thin layers of grain between the corners, located vertically in a staggered order (through rad), with greater speed than in the layers of grain, right between the receiving and exhaust ducts, alternating through the odil, from the underlying horizontal rows of ducts. Due to the active horizontal blowing of thin layers of grain between the ducts in the upper zone 6: the grain is most successfully dried, with less: m energy consumption for ventilation, while at the same time ensuring uniform heating of the grain, which has a destructive effect on granary pests.

The temperature condition in zones 5 and (5 is maintained by thermostat 14, control valves installed in the mixing chamber 9.

At the ends of the car, there is an aspolation furnace, a mixing chamber, and a power plant of the dryer, consisting of an internal combustion engine 15 and a generator 16, which power the electric motors of the fan and grain transporting devices, and, if necessary, the electric motor 17 to drive one of the axes of the car through a gearbox 18. In the dryer, a bell alarm is applied, setting the degree of filling of the bunkers 7 with grain over the shafts and controlling it from a rotary valve that interacts with the grain in each of these shafts.
