Skimming and separation device
First Claim
1. A skimming and separation device comprisingan outer casing provided with constructions to directly or indirectly fasten all parts, defining an open container,a floater configured to create the skimming function of the device,a vertically arranged bellow extending between the outer casing and the floater, wherein the floater is attached at its lower side to the vertically arranged bellow allowing the floater to adapt flow into a substantially circum volume and allowing the floater to move from an upper position with essentially no flow into the container to a lower position allowing flow of water and debris follow the contours of the floater in a downward direction into the device,a power device with a propeller, wherein said power device is configured to be controlled by a control signal from a control box such that various kinds of flows and pressures may be generated to control the in-flow and outflow of the device, and wherein the power device is fastened to the outer casing,a bypass member being in fluid communication to an under pressure source via a suction tube, such that, during operation, an essentially continuously under pressure suction force is available at the bypass member, wherein said bypass member is structured to continuously subject debris and floating pollutions accumulated on an upper surface in the skimming and separation device to said suction force such that the debris and floating pollutions will enter the suction tube directly and to facilitate a continuous flow of debris and floating pollutions to a tank, anda guiding unit structured to be horizontally arranged along said floater, and wherein said guiding unit is provided with inwardly directed guiding fingers structured to guide solid debris directly to a discharge zone subjected to under pressure by said suction tube.

Abstract
A skimming and separation device comprising an outer casing (1) provided with constructions to directly or indirectly fasten all parts, defining an open container (2), and a floater (3) configured to create the skimming function of the device, the floater is attached at its lower side to an essentially vertically arranged bellow (4) allowing the floater to adapt flow into a substantially circum volume and allowing the floater to move from an upper position with essentially no flow into the container (2) to a lower position allowing flow of water and debris follow the contours of the floater (3) in a downward direction into the device. A power device (8) is provided and includes a propeller to achieve in-flow and outflow of the device. The device further comprises a bypass member (B) being in fluid communication to an under pressure source via a suction tube (12), such that, during operation, an essentially continuously under pressure suction force is available at the bypass member. The bypass member and a guiding unit arranged in the device are both structured to continuously subject debris and floating pollutions to be accumulated on an upper surface in the skimming and separation device and to be subject to the suction force such that the debris and floating pollutions will enter the suction tube (12) directly and to facilitate a continuous flow pollutants to a tank.
