Patent ID: 6868974

Claim:
A continuously operating sedimentation filtration device for cleaning a contaminated processing liquid, the sedimentation filtration device comprising: a sedimentation container having an overflow; several plate-shaped filter elements, having a working position in which the filter elements are arranged at a slant and extend parallel to one another at a spacing to one another, wherein the filter elements form a filter body arranged in the sedimentation container; a removal device for removing sediment deposited in the sedimentation container; a clean liquid tank connected to the overflow of the sedimentation container for receiving cleaned processing liquid having passed through the filter body; a supply comprising at least two supply ideas for introducing the contaminated processing liquid into the sedimentation container, wherein the at least two supply pipes are connected to the sedimentation container on opposed sides of the sedimentation container adjacent to or before the filter elements; wherein between a bottom side of the filter body and a bottom of the sedimentation container a settling chamber is formed, wherein the settling chamber is filled with processing liquid; wherein the settling chamber has a vertical height of at least ⅕ of a vertical height of the filter body; a separating plate provided between the filter body and the at least two supply pipes and configured to separate the processing liquid supplied via the at least two supply pipes from the filter body and to guide the processing liquid into the settling chamber, so that the processing liquid flows from the settling chamber through the filter body in a direction from the bottom to the top; wherein the removal device for the deposited sediment is a scraper belt arranged on the bottom of the sedimentation container and guided from a horizontal running direction across the bottom of the sedimentation container into a slantedly upwardly extending removal direction across at least two rolls or pinions arranged in the sedimentation container in a vertically staggered position relative to one another.
