Abstract
A device having a funnel structure (connected to a separating arrangement by a base pipe is disclosed. The base pipe is horizontal and arranged between the funnel structure and the base pipe. The base pipe is also a vertical suction pipe. The device includes a pressure pipe which is parallel to the base pipe. The funnel structure is slightly below the water surface. In operation, water and floating waste pass over the edges of the funnel structure and swirl into the suction pipe. A jet of water may be injected through the pressure pipe to the base pipe. A flow gradient may then be formed in the base pipe and the differently sized waste objects may separate. If the water contains liquid waste, the speed of the water jet may be adjusted in such a way that the liquid waste and water do not form an emulsion.
Claims11
A device for collecting waste material floating on or near a water surface, the device comprising:
- a funnel structure having a funnel edge, a funnel surface and a bottom, a base pipe, a pressure pipe and a separating arrangement,
- a hole arranged in the bottom of the funnel structure, the hole configured to be connected to the base pipe,
- wherein the base pipe leads to the separating arrangement, and the base pipe is configured to be horizontal at least near the funnel structure,
- wherein the pressure pipe is configured to blow a jet of water into the base pipe when the device is in use, and wherein the diameter of the pressure pipe is smaller than the diameter of the base pipe,
- wherein the funnel edge is arranged at least partly under the surface when the device is in use,
- wherein the device is further configured to move water containing waste material to the separating arrangement, and the device further comprises a suction pipe having a first end fixed to the hole and a second end fixed to the base pipe to configure a curved wall below the hole,
- wherein the diameter of the suction pipe and the diameter of the base pipe are equal or comprise a variation in their diameters of less than 10%,
- wherein the pressure pipe comprises an opening arranged in the curved wall such that a longitudinal axis of the jet of water at the opening and a longitudinal axis of the base pipe are convergent and a jet of water is aimed to the center of the base pipe and
- wherein a slope of the funnel surface is between 5 to 20 degrees with respect to a horizontal plane.
