Abstract

For increasing the capacity of a continuously operating sedimentation filtration device, it is suggested to supply the processing liquid to be cleaned before or adjacent to the filter body (2) on opposed sides into the sedimentation container (1), wherein underneath the filter body (2) a comparatively high settling chamber (7) is formed and between the filter body (2) and the supply lines a separating plate (6) is provided so that the processing liquid to be cleaned is guided mandatorily into the settling chamber (7). The cross-sections of the supply lines provided on opposed sides are comparatively large so that only minimal flow velocities of the incoming medium will occur.

Claims (17)

1. Continuously operating sedimentation filtration device for cleaning contaminated processing liquid such as cooling agents; hydroforming water; drilling, rolling, grinding and turning emulsions; rinsing water; and the like, comprising a sedimentation container with a plurality of plate-shaped filter elements, arranged at a slant and extending parallel to one another at a spacing to one another, the filter elements forming a filter body, further comprising a removal device for the deposited sediment, a supply opening into the sedimentation container for introducing contaminated processing liquid, and a clean liquid tank connected to an overflow of the sedimentation container for receiving the cleaned processing liquid, wherein, for supplying the processing liquid into the sedimentation container (1), at least two connecting sockets are provided that open on opposed sides of the container adjacent to or before the filter elements (3), wherein between the bottom side of the filter body (2) and the bottom of the sedimentation container (1) a settling chamber (7) filled with liquid is provided, whose vertical height is at least 1/5 of the vertical height of the filter body (2), characterized in that a separating plate (6) is provided between the filter body (2) and the connecting sockets which separates the supplied processing liquid from the filter body (2)and guides it mandatorily into the settling chamber (7), from where the processing liquid flows through the filter body (2) from the bottom to the top, and wherein the removal device for the deposited sediment is a scraper belt (16) guided from a horizontal running direction across the bottom (18) of the sedimentation container (1) into a slantedly upwardly extending removal direction across at least two rolls (21, 22) or pinions that are vertically staggered relative to one another.
2. Sedimentation filtration device according to claim 1, characterized in that the supply for introducing the contaminated processing liquid is vented.
3. Sedimentation filtration device according to claim 1, characterized in that the connecting sockets for introducing the processing liquid into the sedimentation container (1) are widened to a box shape.
4. Sedimentation filtration device according to one of the claims 1 or 3, characterized in that the filter elements (3) or the filter body (2) is pivotable, preferably by means of a pneumatic drive device, from the slanted working position into a cleaning position extending approximately perpendicularly to the horizontal.
5. Sedimentation filtration device according to one of the claims 1 to 4, characterized in that, for cleaning the filter elements (3) or the filter body (2), blowpipes that can be loaded with compressed air are provided underneath the filter body (2) in the sedimentation container (1).
6. Sedimentation filtration device according to claim 5, characterized in that the blowpipes can be controlled individually by compressed air valves with compressed air.
7. Sedimentation filtration device according to claim 5 or 6, characterized in that the blowpipes have compressed air connectors on both ends.
8. Sedimentation filtration device according to one of the claims 1 to 7, characterized in that an unbalance-type shaker is provided for cleaning the filter elements (3) or the filter body (2).
9. Sedimentation filtration device according to one of the claims 1 to 8, characterized in that the scraper belt (16) is comprised of removal strips (17) guided on chains and arranged parallel to one another at a spacing to one another, which strips run across the bottom (18) of the sedimentation container (1).
10. Sedimentation filtration device according to one of the claims 1 to 9, characterized in that in the bottom area of the sedimentation container (1) at least two spacer guides are provided extending transversely to the movement direction of the removal strips (17) and resting against the underside of the removal strips (17).
11. Sedimentation filtration device according to one of the claims 1 to 10, characterized in that, for driving, for deflecting, or for tightening the chains of the scraper belt (16), pinions or cylindrical rolls with grooves are provided and engaged by the chain members (51), (52) of the chains in a positive-locking way.
12. Sedimentation filtration device according to one of the claims 1 to 11, characterized in that the filter elements (3) have spacer elements in the form of spacer strips (4) extending parallel to one another.
13. Sedimentation filtration device according to one of the claims 1 to 12, characterized in that an oil removal belt, running above the liquid level and provided with rib-shaped strippers positioned at the spacing to one another; a skimmer; or an oil suction pump is provided for removal of foreign oil floating on the processing liquid.
14. Sedimentation filtration device according to one of the claims 1 to 13, characterized in that in the sedimentation container (1) above the filter body (2) two laterally arranged at least partially slantedly extending stay-shaped floating oil barriers (26) are provided.
15. Sedimentation filtration device according to one of the claims 1 to 14, characterized in that the liquid level of the processing liquid in the sedimentation container (1) is adjustable by means of a level control.
16. Sedimentation filtration device according to claim 15, characterized in that the liquid level of the processing liquid is detected by ultrasound sensors and is adjustable by controllable governing devices such as overflow flaps and the like.
17. Sedimentation filtration device according to one of the claims 1 to 16, characterized in that for removal of the sediment (58) from the removal strips (17) of the scraper belt (16) a pendulously suspended stripper device (24) is provided acting abrasively on the topside of the removal strips (17) and moving relative to the scraper belt (16) or the removal strips (17).
