Abstract

A processing device for grey water for a rail vehicle includes a grey water container, a grey water supply in an inlet region, a drain for processed grey water in an outlet region, and a slotted filter between the inlet and outlet regions that has at least one movable sliding member which touches the base of the grey water container in a lowered position and is lifted off the base in a raised position. The base of the grey water container rises from the inlet region to the outlet region. A cleaning outflow is disposed in the inlet region on the base side. A fresh water supply for supplying fresh water is disposed in the outlet region. A rail vehicle having at least one processing device for grey water for a toilet module or toilet bowl is also provided.

First claim

The invention claimed is:

1. A grey water processing device for a rail vehicle, the processing device comprising:
a grey water container including an inlet region, an outlet region and a base defining a base side, said base being higher in said outlet region than in said inlet region;
a grey water supply disposed in said inlet region;
a drain disposed in said outlet region for grey water processed in said grey water container, said drain having an opening for passage of processed grey water into said drain, said opening being spaced apart from said base of said grey water container, and said drain having a pipe guided through said base of said grey water container and protruding into said grey water container;
a slotted filter disposed between said inlet region and said outlet region, said slotted filter having at least one sliding member being movable between a lowered position touching said the base and a raised position raised from said base, and said slotted filter having at least one fixed slotted member;
said at least one fixed slotted member and said at least one sliding member being disposed relative to each other in said grey water container to form a gap between said at least one fixed slotted member and said at least one sliding member at least in said lowered position of said at least one sliding member to cause grey water in said inlet region intended to be filtered to flow through said gap to reach said outlet region;
said at least one sliding member having a face facing said at least one fixed slotted member and a resilient lip disposed on said face;
said resilient lip scraping off adhesions on said face of said at least one fixed slotted member facing said at least one sliding member upon said sliding member moving from said lowered position into said raised position;
a cleaning outflow disposed at said base side in said inlet region; and
a fresh water supply disposed in said outlet region for supplying fresh water.

2. The grey water processing device according to claim 1 , wherein said fresh water supply is directed against a wall of said grey water container.

3. The grey water processing device according to claim 1 , wherein said grey water container has mutually parallel side walls between said inlet region and said outlet region, and said at least one sliding member is plate-shaped and is disposed perpendicularly to said side walls.

4. The grey water processing device according to claim 3 , wherein said side walls have guides for guiding said at least one sliding member.

5. The grey water processing device according to claim 1 , wherein said at least one fixed slotted member has a fixed scraper facing said at least one sliding member, resiliently deforming said resilient lip of said at least one sliding member upon said sliding member moving from said raised position into said lowered position, scraping off adhesions on said lip releasing said gap between said at least one sliding member and said at least one slotted member in said lowered state of said at least one sliding member.

6. The grey water processing device according to claim 1 , which further comprises:
a jet breaker disposed in said grey water container and orientated toward said grey water supply, said grey water supply being directed against said jet breaker for splitting a grey water jet discharged through said grey water supply into said grey water container; and
an overflow, said jet breaker shielding said overflow in a direction of said grey water supply.

7. The grey water processing device according to claim 1 , wherein said at least one movable sliding member includes at least three movable sliding members.

8. The grey water processing device according to claim 1 , which further comprises a filling level sensor disposed in said outlet region.

9. A rail vehicle, comprising at least one grey water processing device according to claim 1 .

10. The grey water processing device according to claim 1 , wherein said grey water container has an elongated shape with said inlet region at one side, said outlet region at another side and said slotted filter between said inlet region and said outlet region.

11. A grey water processing device for a rail vehicle, the processing device comprising:
a grey water container including an inlet region, an outlet region and a base defining a base side, said base being higher in said outlet region than in said inlet region;
a grey water supply disposed in said inlet region;
a drain disposed in said outlet region for grey water processed in said grey water container, said drain having an opening for passage of processed grey water into said drain, said opening being spaced apart from said base of said grey water container, and said drain having a pipe guided through said base of said grey water container and protruding into said grey water container;
a slotted filter disposed between said inlet region and said outlet region, said slotted filter having at least one sliding member being movable between a lowered position touching said the base and a raised position raised from said base;
said slotted filter including at least one fixed slotted member facing said inlet region;
said at least one fixed slotted member and said at least one sliding member defining a gap therebetween; and
said at least one fixed slotted member having a guiding sheet shielding said gap in a direction of said grey water supply;
a cleaning outflow disposed at said base side in said inlet region; and
a fresh water supply disposed in said outlet region for supplying fresh water.
