Problems solved by technology

However, this known device has the considerable disadvantage that the dimensions of the inner chamber, especially around the distribution element arrangement, must be relatively large, since these elements require a certain height range of the inner chamber.
In addition, such distribution elements are exposed to the stresses of the interior, such as the atmosphere in the interior and the temperature of the interior, so that they are subject to greater wear, moreover require frequent maintenance, and moreover frequently cause malfunctions
Another disadvantage is that this arrangement of the distribution elements likewise requires a more expensive construction to withstand the greater loads in the interior of the reactor or furnace shaft

Embodiment Construction

[0027] The reduced material 3 , sponge iron, is introduced in a loose state into the melter-gasifier 1 , ie a shaft furnace, via an obliquely arranged channel 2 formed as a downcomer. The downcomer opens into an opening 4 in the upper part 5 of the melter-gasifier 1 , which is designed in the shape of a dome. In the melter-gasifier, in a melter-gasification zone 6 formed by a moving fixed bed, reducing gas is produced from a carbon carrier such as coal and an oxygen-containing gas to reduce iron ore. The gas discharge line, not shown in detail, leads to a fixed bed, not shown in detail, as described in AT403930B.

[0028] In order to feed the loose material 3 (i.e. sponge iron) as evenly as possible onto the surface of the moving fixed bed, a valve formed as a rotary valve is provided in the downcomer near the entrance into the inner chamber 7 of the melter-gasifier 1 Distribution element 8. Here, the pivot axis 9 of the distribution element 8 is arranged approximately paral...

Abstract

The invention relates to a method for loading a pourable material (3) in a container (7), said material being supplied by gravity forces through a channel (2) which is arranged in the opening (4) of the container (7). In order to obtain a desired material (3) distribution in the container (7), said material, a little bit before the passage thereof through the opening (4), i.e. inside the channel (2), is exposed to forces modifying the displacement direction of the material given by the channel (2) and the gravity forces.

Description

technical field [0001] The invention relates to a method for filling a chamber with loose material and a device for carrying out the method, wherein the material is conveyed by gravity via a channel to the opening of the chamber. Background technique [0002] Many methods and devices for charging shaft furnaces such as blast furnaces, melter-gasifiers, converters or other reaction vessels are known (DE 1 907 224 A, EP 0 436 718 B1, EP0 010 627 B1, JP 2000178624 , JP 59226108 and JP 6256829). In all these known methods and devices, the bulk material to be charged passes through a channel formed as a downcomer to an opening in the upper area of ​​the shaft furnace and then either through a deflection device (for example in DE 1 907 224 A) in the direction of movement Falling into the inner chamber of the reactor or furnace shaft with a deflection, or directly into the inner chamber without a deflection device (eg in EP 0 436 718 B1 or EP 0 010 627 B1). [0003] Without a def...
