Description

Industrial unloading devices of furnaces for producing thermoanthracite are very imperfect but their design.

One of the main drawbacks of such devices is the jamming of the finished product in them with subsequent crushing. In this connection, since thermoanthracite has a high mechanical strength, a need arises to significantly strengthen the design of the working parts and mechanisms of the unloading device. Most of these devices are bulky and require a great height (3-4 m) for leakage.

The known designs of the discharge devices, provided that there is a splitter dividing the charge stream into two parts, make it impossible to achieve the necessary movement of Ptichty, which provides the same thermal and gas treatment of anthracite pieces. This () circumstance forces the manufacturers to slow down the burning process, due to which the bulk pressure is reduced.

To eliminate the noted deficiencies in the proposed design of the unloading device, a rotating pallet with a hole in the center, above which the divider is located, is used.

The drawing shows a schematic sectional view of a loading device according to the invention.

In the center of the lower round part there is a shaft; the furnaces are mounted a fixed cone divider / and a funnel 2, below which there is a rotating conical tsoddon 5 driven by the drive 4. In the center of the pallet there is an opening 6, and under it is a sealed valve 5 (one of the existing structures), from which the finished anthrax anthracite is emitted .

The proposed device works as follows.

The flow of charge A deviates from the center to the periphery and, meeting the wall of the funnel 2, inclined at an angle B, is sprinkled to the tray 3. The mixture forms a funnel above the circumference of the base of the cone / and below the circumference of the hole 6 in the pallet 3. Limited by the angle of repose C ujHXTa will not be poured from pallet 3 into hole 6 until the pallet has been rotated.

Fold, it 3 is a truncated cone, the lateral surface of which may be smooth, or tides protruding to a certain height in the form of curved bands diverging from aperture 6 are made on it.

The proposed unloading device eliminates jamming and crushing of the finished product.

This unloading device provides continuous unloading of the finished product from the furnace shaft and easy adjustment of the furnace traffic flow.
