Berlin, Germany, 'IMPROVEMENTS IN CONTINUOUSLY ACTING APPARATUS FOR
RINSING, WASHING AND SEPARATING STRONTIUM SACCHARATE AND OTHER
MATERIALS, ALSO APPLICABLE FOR SEPARATING SOLUBLE OR INSOLUBLE PARTICLES
FROM OTHER BODIES." (A communication from the "Zeitzer Eisengieserei &
Maschinenbau-Aktien-Gesellschaft" at Zeietz in the German Empire),
This invention refers to a continuously-acting washing or rinsing apparatus
which is especially intended for the washing of strontium saccharate but is also
suitable for separating soluble or insoluble materials which adhere to other bodies.
The washing appliances used consist of boxes with sieve bottom and adapted to
receive the bodies to be washed or separated. These sieve boxes dip in the running
liquid and receive an up and down motion in such manner that thus a rinsing and
washing or separation of the bodies are thereby effected.
The whole apparatus is composed of a number of sieve boxes which are arranged
in a circle around a central shaft and dip in special washing tanks which are
connected by pipes.
The sieve boxes are connected to a framing which can turn round a central shaft,
whereby the sieve boxes can be successively brought over all the washing tanks;
but the rinsing liquid flows in a direction opposite to that of the sieve boxes from
one washing tank to the other and becomes gradually saturated with the washed
out materials while the masses or material that has to be rinsed is gradually freed
from the bodies adhering thereto in such manner that the most saturated rinsing
liquid comes in contact with the freshly charged sieve-boxes, and the clean rinsing
liquid with the most washed out bodies. By this mode of working, a most rational
separation or washing and concentration of the solutions are effected, as the most
DD.11

page_text: washed material always comes in contact with such a rinsing liquid which has
taken up the least of the bodies adhering to the material under treatment.
The sieve boxes may be suspended in fork-ended rods which are guided in a star-
shaped framing fixed on the central shaft and are connected two and two to
opposite ends of levers which are jointed to the central shaft and receive oscillating
motion from cranks or eccentrics by means of connecting rods, which can be discon-
nected as required, the central shaft along with the sieve boxes and other gear
can be raised bodily by means of a hydraulic press ram beneath the shaft or by a
lever or other suitable means, when it is required to lift out the sieve boxes and to
drop them into the next following rinsing tanks, and to lift the last sieve box out
of the last rinsing tank for the purpose of discharging its contents and recharging
it for the next stage in the process, suitable stops may be provided for adjusting
the position of the sieve boxes relatively to the tanks. The communicating pipes
are so arranged, that the liquid flows from the bottom of one tank to the top of
the next.
