Embodiment Construction

[0014] Functional principle

[0015] as from figure 1 As can be seen, the feeding device comprises a silo 1 with a fluidizable element 3, such as one or more pads, in the bottom of the silo. This element may be activated at position 4 by pressurized gas (not shown), such as air flowing through a controllable valve. The bottom of the silo and / or the element is inclined towards the outlet of the silo at an angle preferably between 1-5°.

[0016] At the outlet is arranged a supply reservoir, shown in this example comprising a generally vertical, downwardly converging part 5 of conical shape and a top plate 6 as its main element. A top plate 6 is arranged above the inlet of the conical part 5 and the top plate 6 will confine the material inside the silo to induce pressure in the material inside the conical part. Furthermore, the structural details of the roof in contact with the two side walls and one rear wall of the silo and having a projected area overlapping a portion of th...

Abstract

Method and device for feeding material in a fluidized state through a silo (1), inside the silo (1), in its bottom, with at least one fluidizable element (3), wherein when said element is activated , said element is capable of conveying material towards a first outlet and a controlled dose further to the fluidizing conveyor (11) via a second outlet (9). Material fed to the first outlet is received by a feed reservoir formed as a generally vertical section (5), preferably a conical section, which converges downwards onto said conveyor (11). Above the reservoir is arranged a top plate (6) which makes the pressure in the material in the reservoir independent of the filling speed of the silo.

Description

technical field [0001] The present invention relates to methods and apparatus for supplying fluidizable material. In particular the invention relates to feeding materials such as alumina and / or fluoride to aluminum electrolytic cells. Background technique [0002] Traditionally, almost all existing electrolysis technologies serving aluminum production are equipped with silos and volumetric feeders and they are all controlled by volumetric measurements. This will subject the process to variations in material density (typically ±10%). Furthermore, this variation, combined with other storage and handling considerations such as segregation, can, and did, have a negative impact on tank supply stability. In addition, most electrolyzers are also equipped with silos today, so the newly developed units are based on an improved concept. [0003] In the past, several feeders have been invented and patented for these types of materials and applications. For example, from EP605037B1 ...
