DE2348344A1 - Device for removing oil slicks on water - includes capture funnel, barrier wall, pump and floats consisting of inflatable spheres - Google Patents

Abstract

The capture funnel is in the form of a floating hollow body. In the funnel opening is a truncated cone-shaped displacement body forming an inlet gap and the floats consists of inflatable spheres or similar bodies. The funnel and the displacement body are filled with synthetic foam and the floats are fixed to support arms which are pivot-connected to the funnel. The capture funnel is provided with a strainer and the displacement body is height adjustable relative to this strainer by means of suitably positioned screws.

Device for the suction of pumpable floating on water Impurities

The invention relates to a device for sucking up water floating, pumpable impurities with a collecting funnel, a barrier wall arranged above - one below arranged pump and floats with variable displacement.

Such devices are required, in particular, to suck off oil that has spilled onto standing or flowing water and to be able to pump through pipes into collecting tanks set up on the bank or on ships.

A device is disclosed in German Offenlegungsschrift 2 051 577 of the genus mentioned at the beginning known, at the AuiEingtrichter, The barrier wall and the pump are suspended from a dismountable, star-shaped rod, which is open at the lower end, barrel-shaped floats with variable water displacement supports. The dismantling of this known device results in the disadvantage that it is initially at the point of use must be assembled. A serious technical disadvantage of this known device is that the suction funnel, the barrier wall and the pump existing suction unit itself is not buoyant and only with the rigid and bulky, barrel-shaped floats to the correct suction height e Inge can be swum. Another serious technical one The disadvantage of this known device is that the collecting funnel is open at the top, so that its degree of filling depending on the height of the inlet edge of the collecting

funnel and the pump output constantly fluctuates. Through this it becomes next to impossible to get the inlet edge of the collecting funnel Rait the floats to swim to the correct altitude.

The invention is based on the object of creating a device of the type mentioned at the outset, in which the running edge the collecting funnel exactly to the level of the impurities can be sworn in and which is ready for use as a compact device without significant set-up times. Is resolved this task in that the collecting funnel as "" buoyant Hollow body is formed that in the opening of the Collecting funnel a frustoconical displacement body is arranged to form an inlet gap and that the

Floats made from inflatable balls or similar bodies exist. .

In a practical embodiment, the collecting funnels are and the displacement body is foamed with a plastic so that it still acts as a float even in the event of a leak remain functional. Furthermore, it has proven to be useful to pivot the float with the collecting funnel to attach connected support arms, so that the entire device can be folded into a compact transport position. Finally, it is also useful in front of the inlet gap To arrange a sieve in order to prevent foreign objects such as wood, reeds' od. The like. Clogging the inlet gap or damage the pump.

In a further embodiment of the invention, the inlet gap is designed so that it extends from the outside to the inside in cross section widened conically so that the volume of the inlet gap of from outside to inside remains approximately constant. In order to be able to change the height of the inlet gap and thus also its volume, has it has proven to be expedient to attach the displacement body to the sieve in a height-adjustable manner with screws.

The device designed according to the invention has the advantage that the pump unit consisting of the inlet funnel, the displacement body and the pump is already buoyant and the additional float only serve to open the inlet gap to swim to the level of the layer with the impurities to be pumped out. With the individually inflatable Floats can also compensate for a slight inclination of the pump unit on the side of the pressure hose, so that an absolutely horizontal position of the inlet gap can be achieved. Since the pump unit develops enough of its own buoyancy, the additional floats can be designed small so that they can be folded for transport can.

Further details and advantages of the subject matter of the invention emerge from the following description of the associated Drawings in which a preferred embodiment of the device according to the invention is shown schematically is. In the drawings show:

Fig. 1 A device for the suction of floating on bodies of water, pumpable impurities in side view;

Pig. 2 the same device to illustrate the inlet gap partially cut.

A device designed according to the invention has a collecting funnel 1, which is filled with foam la, a motor pump 2 fastened underneath, at least three inflatable floating bodies ~ j>, ^{j5 v} , which are pivotably articulated to the collecting funnel 1 via support arms 4,4 , and a displacement body 5 * which is also filled with foam 5a.

The displacement body 5 is frustoconical on its underside formed so that it büdet with the top of the collecting funnel 1 a EJriaufspalt 6, which extends in the direction of the Motor pump 2 widened conically in cross section so that the volume remains constant. A sieve 7 is attached to the collecting funnel 1, to prevent foreign bodies from entering the inlet gap 6

prevent. On the sieve 7 is the displacement body 5 with several Screws 8 fastened adjustable in height so that the cross section of the inlet gap 6 can be changed.

Each float J5,; j 'is via an air hose 9 with a Valve box 10 connected, which is stationed on the bank or on a ship and the separate Aufb] äsen and emptying of the floating body Jj, Jj 'allows.

A submersible circuit 11 is arranged under the motor pump 2, which causes it to be switched on only in the submerged state can be and is automatically switched off when the device is removed from the water. The power supply to the Motor pump 2 takes place via a cable 12, while the extracted impurities are discharged via a pressure hose IJj and in can be collected from containers placed on the bank or on a ship.

The collecting funnel 1 and the displacement body 5 are dimensioned so that that the device is just buoyant and the mouth of the Sinlaufspaltes 6 just below the surface of the water lies. The motor pump 2 suspended below the collecting funnel 1 with the immersion circuit 11 has a stabilizing effect the entire device, so that an approximately horizontal position is guaranteed. The exact leveling of the mouth of the inlet gap 6 to the level of the impurities to be sucked off takes place with the floats Jj, Jj '. With floats J5, Jj ' a slight inclination of the inlet funnel 1 to the side of the flanged pressure hose can also be compensated for IJj is possible. For this purpose, the floats J5, Jj 'are filled with air separately via the valve box 10 and also emptied again.

The floats Jj, Jj 'are completely emptied for transport and then folded on their support arms 4,4 'under the collecting funnel 1, so that a very compact device is created, which even can be accommodated in a passenger car in an emergency.
