Description

one

The invention relates to agricultural production and can be used in the construction of grain drying bins.

Dryers are known that contain a cylindrical container with a perforated-bottom and a rotating tool fixed at its center to select bulk material from the bottom layers and have a device for supplying a drying agent.

Nedbstatkami known dryers are damage to the rotary working body of the discharged bulk material from overheating and abrasion.

The aim of the invention is to reduce the loss of bulk materials.

This goal is achieved due to the fact that the rotary working body is made in the form of a beam having an L-shaped cross section and resting on the roller.

FIG. 1 shows the storage scheme of the bulk | 1x materials; in fig. 2 shows the storage in the plan; in fig. 3 - shows a cross-section aa of the rotary working body.

The bulk materials storage has a cylindrical tank 1, an axial tube 2, a perforated bottom 3, a pressure chamber A, a discharge conveyor 5, a drive 6, a beam 7,

10 roller 8, protective cone 9, valve 10.

The cylinder 1 has a perforated bottom 3, an axial tube

IS 2 with a flap 10. In the center of the tank 1, in the recess, there is an unloading conveyor 5- A protective cone 9 entering the axial tube 2 is located above the conveyor 5. From the cone 9 the L-shaped beam 7 radially extends radially on roller 8. Under the cone 9 is placed the actuator 6, which rotates the beam 7 and the cone 9.

The storage operation consists in loading the cylindrical container 1 with a bulk material. After loading under the perforated bottom 3, heated or cold, dry air (drying agent) under pressure is supplied to the pressure chamber k. The shutter 10 is closed. The air passes through the bottom perforation into the cylindrical tank 1. With the penetration of the bulk material, the air dries it and carries away the moisture released from the material. After the bulk material is dried, the flap 10 opens and the actuator 6 is turned on. The actuator 6 starts a perforated bottom 3 of the beam 7. The beam 7 is L-shaped and the bulk material falls asleep above it, set at an angle of repose. Air under pressure finds the path of least resistance. It enters through the perforations of the bottom 3 under 7 captures the fluidized material flowing with it, moves to the cone 9 and the axial pipe 2. Through the axial pipe 2, the air goes into the atmosphere, and the grain falls on the discharge conveyor 5. The beam 7 collects all the lying

at the bottom there is a layer 3 and therefore the bulk material does not overheat at the bottom. Beam on the material is almost no third. This proves that the goal of the invention is achieved.
