Description

one

In ocHOBiHOM auth. St. No. 333381 described a carousel dryer for agricultural materials, mainly flax heap, containing a ring-shaped drying chamber with a perforated bottom to introduce the coolant into the layer of the material to be dried. The outer walls of the chamber and its bottom are provided with rolling bearings to rotate the outer wall under the action of frictional forces of the dried material located on the bottom, which is rotated by an external drive, and an annular gap is formed between the outer wall and the bottom and is connected to the unloading window dry material, ia example, using a conveyor. The purpose of the invention is to intensify the process of the process by excluding the oscillating mode.

This is achieved by the fact that radial partitions are placed under the perforated bottom of the chamber in the gas distribution box, one of which is located between the windows for entering the heat transfer medium and the cooling air, and the second is rotatably installed to form a cooling sector section of variable cross section.

FIG. 1 shows schematically the described entity; in fig. 2 is a section along A-A in FIG. one.

The carousel bitch contains a ring

a chamber formed by a rotating perforated bottom 1 and ring guards 2 and mounted on the foundation 3, a discharge device 4, as well as a charging device, a heat generator, fans, a drive (not shown). In foundation 3, there are a hole 5 (window) for the introduction of coolant (drying agent), and a hole 6 (window) for the entry of cooling atmospheric air. A fixed radial partition 7 is installed between them. In addition to it, there is a radial partition 8, which is attached pivotally to the central axis 9 and can be installed in any position along the angle of rotation relative to the partition 7. Any frame suitable for transmitting rotation can be used to rotate the partition 8. manual, electric or other drive. The dryer works as follows. The drying agent is fed under the bottom 1 through the opening 5, and the atmospheric air through the opening 6. The passage through the bottom and the wet material loaded onto it, the essential agent produces drying, and the air cools the material. As the lower layer of material dries and cools in the area before the unloading device 4, the material is discharged in layers from the bottom, and the drying chamber is loaded from above with a wet material. The partition 8 is installed in different positions depending on the desired drying mode.

Subject invention

Rotary dryer for agricultural materials, mainly flax heap, according to ed. St. No. ZZZZv, characterized by the fact that, in order to intensify

The drying process by performing ospilliuush, its mode, under the perforated bottom of the chamber, in the gas distribution duct are placed radial partitions, one of which is located between the windows for heat carrier and cooling air, and the second is rotatably installed to form a cooling sector section of variable section.
