Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a radial bin type dryer with ventilation passages inside and outside of double cylindrical perforated plates and a drying chamber between them.

In conventional radial bin type dryers, the grain to be dried is discharged by providing a conical bottom plate at the bottom of the drying chamber that slopes toward the center.
I was doing this from the center of this bottom plate.

However, in this case, when the discharged grains are taken out to the outside or further guided to the upper part of the dryer for circulation, a conveyor device is required to transport the grains from inside the dryer through the outer wall. The structure was becoming more complex.

The present invention eliminates the above-mentioned drawbacks, and provides a radial bin that allows the materials to be dried to be taken out directly from the drying chamber to the outside by utilizing the wind, and that also smooths the flow of this wind power to smoothly discharge the materials to be dried. The purpose is to provide a mold dryer.

Embodiments of the present invention will be described with reference to the drawings.

In Fig. 1, inside the tank 1 are two cylindrical wire meshes that serve as cylindrical perforated plates, namely the inner wire mesh 2.
and an outer wire mesh 3 are provided, and a drying chamber 4 is installed between them.
However, a central ventilation shell 5 is formed inside the inner wire mesh, and a peripheral ventilation shell 6 is formed on the outside between the outer wire mesh 3 and the tank 1. Inlet port 7
The grains introduced from the drying chamber 4 are transported to an upper position by the elevator 8, enter the drying chamber 4 through the drying chamber entrance 9, and are led to the elevator 8 through the discharge port 21 provided in the cylindrical wire mesh 3 at the bottom of the drying chamber 4. He is then transported again by elevator 8 and circulated. And the central ventilation trunk 5
The surrounding ventilation shell 6 communicates with a blower 13 and exhaust ports 14, 15 through ventilation passages 11, 12, and valves 16, 17, 18 are provided in the ventilation passages 11, 12 to alternately switch the ventilation direction. drying process. In addition, the central ventilation barrel 5 is provided with a stopper 19 that can be moved up and down, and is moved up and down by a hoist 20 according to the height of the grains in the drying chamber 4, and a valve 26 is installed at the entrance 9 of the drying chamber. installed to prevent hot air from escaping.

There is a discharge port 2 at the border of the lower chamber 10 at the bottom of the drying chamber 4.
A flat perforated plate 23 having a large number of holes 22 facing obliquely upward and having a circumferential component is provided on the upper part of the drying chamber 4, and the lower part of the drying chamber 4 is partitioned from the inner wire mesh 2 toward the discharge port 21. A facing partition plate 24 extending in the radial direction is provided, and blow-up prevention plates 25 projecting on both sides of the partition plate are formed on the upper part of the partition plate 24 so as to be inclined diagonally downward.

When discharging the material to be dried in the drying chamber 4, ventilation is provided through the ventilation passage 12 and the discharge port 21, which was closed during drying.
When opened, the wind passing through the perforated plate 23 from bottom to top carries the material to be dried to the discharge port 21 through the numerous holes 22 having components directed toward the discharge port 21 . discharge from.

At this time, the wind traveling toward the discharge port 21 in the circumferential direction tries to collide at the discharge port 21, but the lower part of the drying chamber 4 is partitioned and the air flows from the inner wire mesh 2 to the discharge port 21.
Partition plate 24 extending in the radial direction facing toward 1
Collision is avoided and the liquid flows out toward the discharge port 21.

Further, the wind that hits the partition plate 24 and tends to flow upward is prevented from moving by the blow-up prevention plate 25 formed on the upper part of the partition plate 24.

As described above, according to the present invention, in a radial bin type dryer where the internal and external ventilation cylinders are formed by double cylindrical perforated plates and the drying chamber is provided between them, without using a conveyor mechanism, The material to be dried inside the drying chamber can be reliably discharged to the outside using wind, and the flow of this air extends in the radial direction from the inner wire mesh that partitions the lower part of the drying chamber toward the discharge port. The air flows smoothly to the outlet without any interference due to the partition plate, and the blow-up prevention plates formed protruding from both sides of the partition plate can prevent blow-up caused by the wind colliding with the partition plate. , the material to be dried can be smoothly discharged from the discharge port.
