Description

The invention relates to a particularly useful for the heat of the waste pellets of a rotary kiln and for holding the dust carried away by them.

In the proposed device, to maintain the flow of the lumpy raw material through which the furnace gases are passed, a drum rotating on a horizontal axis with recipe walls is provided. The lower part of the said drum is in a closed chamber, isolated from furnace gases and equipped with a valve for discharging the raw material entering it.

In FIG. 1 shows a longitudinal section of the device; Srig. 2 is a section along the line AB in FIG. one.

In the proposed device (Figs. 1 and 2), a drum / rotating on the horizontal axis, into which gases are passed through the channel 2, is expelled from the rotary kiln 3, is designed to maintain the flow of lumpy raw material through which the furnace gases flow. into the chamber 4, the gases, along the hog 6, go outside.

The drum 7, which is closed from one of Topues 7, is in its lower part B closed chamber 8. Only raw materials that did not fall directly into the oven through tray 9 fall into this chamber; it is collected at the bottom of the chamber S and, as required, when the valve W is opened, it is passed into the furnace.

The discharge of gases through the feed funnel // is not possible in this case, since it is tightly closed with a large amount of raw materials. A valve 72 is arranged above the tray 9, pressed by means of the load 13 to the raw material with a large amount of dust accumulating on the tray 9; this valve prevents gases from escaping from tray P and at the same time keeps the raw materials from slipping too quickly.

The subject of the patent.
