Estimating the term…
The invention relates to a centrifuge, especially a separator, with a feed tube (3) and/or a distributor (5) for feeding a material to be centrifuged into a centrifuge compartment (9) that is defined by a centrifugal drum (7) and in which a sieve system is disposed. The invention is further characterized in that the sieve system is designed and disposed in such a manner that the flow direction of the material to be centrifuged emerging from the distributor (5) and the flow direction of particles deposited on the sieve elements of the sieve system is identical. The invention further relates to a method for cleaning the centrifuge, according to which preferably a piston slide valve of the centrifuge is opened so that a return flow of liquid through the sieve system removes substances baked to the sieves and/or any impurities.
Centrifuge, particularly a separator,
Centrifuge according to one of the preceding claims, characterized in that ring gaps (19) are formed between the membrane plates (13).
Centrifuge according to one of the preceding claims, characterized in that the spacing rings (15) situated on the inside diameter have bores (31, 35) for draining clarified liquid.
Centrifuge according to one of the preceding claims, characterized in that the spacing rings (15) situated on the inside diameter have ducts (29) for feeding the charged material between the membrane plates (13).
Centrifuge according to one of the preceding claims, characterized in that the spacing rings (15) situated on the inside diameter are disposed directly above one another without any sealing.
Centrifuge according to one of the preceding claims, characterized in that the distributor (2) has bores (25) in its wall (23), which bores (25) lead directly or by way of additional bores/ducts (29) into the ring gaps (19) between the membrane plates (13).
Centrifuge according to one of the preceding claims, characterized in that the spacing rings (15) situated on the inside diameter are provided with drain ducts (31) which connect a ring space (33) between the membrane disks (13a, 13b) of the membrane plates (13) with a draining system (37) for draining the liquid stage.
Centrifuge according to one of the preceding Claims, characterized in that the drain ducts (31, 35) are constructed in a hydraulically separate manner with respect to the feed ducts (29).
Centrifuge according to one of the preceding claims, characterized in that a solids-enriched stage can be discontinuously drained from a solids space (9) of the centrifugal drum (7) by way of openings (41) in the piston slide valve (39) by opening the piston slide valves and/or is continuously drained by way of ducts (37)/ bores or nozzles in the exterior area of the centrifuge compartment (9).
Centrifuge according to one of the preceding claims, characterized in that the openings (41) in the piston slide valve (39) have a nozzle-type design.
Centrifuge according to one of the preceding claims, characterized in that the membrane plates (13) are constructed individually or as several plates (13) as a preassembled unit and are inserted into the centrifugal drum (7).
Method of cleaning a centrifuge according to one of the preceding claims, characterized in that, for cleaning the sieve system, preferably a piston slide valve of the centrifuge is opened up so that a return flow of liquid through the sieve system removes substances baked to the sieve system and/or impurities from the latter.
