Abstract

A separating arrangement for a device for collecting waste material floating on or near the surface of water is disclosed. The separating arrangement includes a first basin and a separating means. The water containing waste is led to the first basin by a transfer arrangement, such as a pipe. The device is configured in such a way that the water coming from the transfer arrangement has a speed gradient, namely, the cross section of the transfer arrangement has areas where the speeds of the water flow are different. The fastest speed component of the water has the highest concentration of waste. The first basin and the separating means are configured in such a way that when the water arrives at the first basin, most of the waste reaches the separating means and does not clog the walls of the first basin.

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.

Abstract

The invention is a separating arrangement (113) for a device for collecting waste material floating on or near the surface of water. The separating arrangement comprises a first basin (111) and a separating means (113). The water containing waste is led to the first basin by a transfer arrangement (104), for example, a pipe. The device is configured in such a way that the water coming from the transfer arrangement has a speed gradient, i.e. the cross section of the transfer arrangement has areas where the speeds of the water flow are different. The fastest speed component of the water has the highest concentration of waste. The first basin and the separating means are configured in such a way that when the water arrives at the first basin, most of the waste reaches the separating means and does not clog the walls of the first basin.

Abstract

The invention is a device (100) which has a funnel structure (103) that is connected to a separating arrangement (105) by a base pipe (104). The base pipe is horizontal and between the funnel structure and the base pipe is a vertical suction pipe. The device comprises a pressure pipe (106) which is parallel to the base pipe. The funnel structure is slightly below the water surface. Water and floating waste pass over the edges of the funnel structure and swirl into the suction pipe. A jet of water is injected through the pressure pipe to the base pipe. A flow gradient is formed in the base pipe and the differently-sized waste objects separate. If the water contains liquid waste, the speed of the water jet is adjusted in such a way that the liquid waste and water do not form an emulsion.
