Abstract

Oil or other floating contaminant 6 is removed from the surface of water by a jet of water 5 directed from a submerged nozzle 1 to induce a flow of contaminant into a collector (not shown). The nozzle is supported by floats and is vertically and angularly adjustable (Fig. 1). <IMAGE>

Description

WATER SURFACE SKIMMER This invention relates to the removal and isolation of floating material from the surface of water.
Most commonly contaminats such as oil, fungi and chemical @aste.
Vairous @@immers are available for lifting oil for example from the @@@@@@@ of water there is a system that emp@@@@ a @@@ of rotating discs in such a way that part of the disc is below the water line, and as the disc is rotated slowly the oil floating on the water adheres to the disc and is lifted clear of the water, where it is then scraped from the died into a @@e@@el for subsequent pumping into a suitable @@ntai@@@.
However these skimmers are specialized pieces of machinery which are not readily available at the sites of oil @pillages Fiurthermore this type of skimmer is not able to handle less sticky materials such as fungi whereby ohter means have to be employed.
According to the present invention there is provided a skimmer comprising a nozzle, means of releasably se@@ring a water @@@@ to the nozzle, floats with extendable a@@@ to support the nozzle, the arms being secured to the nozzle by a @eans that allows adjustement to be made @@ the height and togle of the nozzle relative to the floats.
A specific embodiment of the invention will now be described by way of example with reference to the accompanying drawing in @hi@).
Figure shows an arrangement of the floats and nozzle in the water.
Figure 2 shows the nozzle only, the direction of the water flow and the path taken by the floating contaminant.
Refering to the drawing the skimmer comprises a nozzle 1, a means of adjustement attachment 2, extendable support arms 3, and floats 4, The nozzle which can be attatchend to an existing water pump by means of a flexible hose, is supported by the extendable arms which are connected to the floats.
When the assembly is floated on the containated area of water the nozzle is so adjusted that it is pointing in an upward and angled direction, and at such a depth that the tip of the nozzle is beneath the water and as close to the surface as possible without breaking the surface of the water.
The nozzle of such a diameter and shape that will produce a narrow high velocity jet when water is pumped under pressure throught it. The resulting jhet having a high velocity and subsequent low pressure attracts any fluids or material adjacent to it, which in turn is carried along the path of the jet clear of the surface of the water, this jet being aimed at the opening f an existing containment boom or other suitable vessel not illustred.

Claims (4)

1 A skimmer, comprising a nozzle, means of releasably securing hose to the nozzle, floats with extendable arms to support the nozzle, the arms being secured to the nozzle by a means that allows adjustment to be made to the height and angle of the nozzle relative to the floats.
2 A skimmer, as claimed in claim 1 wherein the principle means of transport for the contaminant is a water jet.
3 A skimmer, as claimed in claim 1 or claim 2 wherein a water jet is used from beneath the water as a means of lifting contaminants above the surrounding water level.
4 A skimmer, as claimed in claim 2 or claim 3 wherein the height and angle of the nozzle can be ajusted relative to the plans of the floats.
