Description

figure 1

The invention relates to devices for loading powdered materials fed into rotating horizontal, for example, drum granulators, dryers, furnaces, and can be used in chemical and other industries that require the supply of material to any given area of the rotating unit while completely eliminating material spillage. .

The purpose of the invention is to improve the uniformity of the feed material.

Figure 1 shows the loading device of a rotary kiln; a longitudinal section; FIG. 2 shows a device, viewed from a perspective view of FIG. 3, section A-A in FIG. 1.

The charging device of the rotary kiln contains a vertical chute and auger 2, freely placed in the central fixed loading tube 3 of the kiln 4.

A part of the spiral 5 of the screw 2 is pressed into the cylindrical body 6, mounted along the axis of rotation of the furnace and rigidly connected to the body 7 of the furnace 4 by means of rods 8. In the cylindrical body 6 along its length 15

There are no slots (not shown) that regulate the discharge of material at a certain point of the furnace.

The loading device of the rotating-5 from the furnace works as follows.

When the furnace 4 rotates together with it, the cylindrical body 6 with alcohol & 5 is rotated. The powder material enters the vertical estrus 1 j O and is caught by the rotating coil 5, forcibly moves along the cylindrical body 6 inside the furnace and through the slots enters the corresponding zone ovens.

The proposed design of the charging device of the furnace, which improves the uniformity of the material supply, ensures that the material enters any predetermined area of the unit with complete installation of the spikes, which is especially important for maintaining, for example, phosphogypsum granulation processes. The supply of phosphogypsum to the drum dryer completely eliminates cold air suction, which contributes to the stabilization of the technological regime of drying phosphogypsum.
