Definitions
- the invention relates to a plant for silver refining according to the Möbius process Processing of part-shaped raw silver, being in the anodes Raw silver storage room as well as an anode sludge storage room below intermediate, anode mud-permeable support for the Raw silver fill are provided, and the support is at least two relative have mutually movable conveyor elements with horizontal axes, which are in extend essentially across the width of the support and between them a gap is provided for the passage of anode sludge.
- raw silver is dissolved anodically and cathodically as fine silver deposited.
- plate-shaped silver anodes from Surround anode bags and each arranged between stripping cathode sheets. The anode bags hold back the gold sludge - if an anode is used up, it is replacing them, taking the gold mud from the anode sacks after turning the sacks inside out is rinsed off.
- the anode body is a frame-like or basket-like structure made of insoluble metal, e.g. made of titanium and is loaded with raw silver granules, so that can be driven continuously.
- An anode sludge collecting area is provided with a sieve bottom.
- the problem of passivation of the anode surface what problem according to the applicant's AT 9700510 by moving the electrolyte in the Anode bed can be countered.
- it can also - even with Electrolyte movement - the problem of blockage of the sieve bottom occur because of it Gaps must be narrow enough to allow only anode sludge to pass through.
- the support for the raw silver fill in the form of at least two oppositely driven rollers with each other parallel axes is provided, the conveyor elements on the roller circumference, in particular axial conveying ribs, for conveying anode sludge between the rollers and optionally between a roller and an adjacent stationary one Exhibit wall.
- the conveyor elements fulfill the other very important function, the complete one To cause the granules to disintegrate by movement - an oscillating one was used for this Movement of the rollers preferred where material during the movement of the Conveyor elements can still remain in the nip after it from the Funding elements for the nip was funded. The same applies to the gap between Roller and floor container wall.
- the support at least two relatively horizontal conveying elements with horizontal Has axes that extend substantially across the width of the support and between which there is a gap for the passage of anode sludge all characterized in that the conveying elements back and forth in the axial direction are provided here.
- those of the granule fill touched surfaces of the conveying elements shifted relative to the granules and provide the necessary abrasion.
- Prisms with 3 or 4 angular ones are preferred as conveying elements Cross section that are arranged so that the gap between them between their edges is so that abrasion material is passed through inclined surfaces to the gap.
- FIG. 1 is a Front cross-sectional view
- Fig. 2 is a side cross-sectional view of one in one Electrolevetuch with basket anode that can be hung between the stripping cathodes Rohsilbergranalienbeschickung.
- FIG. 3 is an enlarged detail from FIG. 2.
- the anode is a flat anode with an overhead Granule receiving room 1 and the wedge-shaped taper below Anode sludge collection chamber 2 with sludge suction pipe 3.
- the granule receiving space 1 has a central, porous partition 4 and on each Side an anode contact plate 5. As is known, is a side, not shown Electrolyte can be flowed through the anode basket - perforated holes are used for this Side walls and diaphragms between granules and side walls intended.
- the granule cutting device 6 has two straight prism bars 6A, 6B square cross-section that run parallel to each other, the prism poles each with their edges against each other and against the side walls of the Granule receiving space 1 are directed, which in its lowermost section 7A, 7B run diagonally to the prism poles.
- a gap S1 between Wall section 7A and prism pole 6A, a gap S2 between prism pole 6A and 6B and a gap S3 is provided between prism bar 6B and wall portion 7B, wherein the gaps preferably have the same width.
- the gap width depends on the Operating parameters of the system, including size and composition the raw silver granules, from - as a guideline can be about 0.5 to about 5 mm can be assumed, preferably between 1 and 2 mm.
- the prism rods 6A, 6B are slidably held in supporting walls 8, where the Push through the edges of the bars, have relief bores 9 so that solids are removed laterally the supporting walls 8 can be removed if the prism rods are parallel are shifted towards each other.
- the inclined sections 7A 7B and the shape of the prism bars 6A, 6B ensure that Direction of the granules to the columns, so that there are no surfaces on which Granular material could remain and there is no risk of clogging.
