Description

DETAILED DESCRIPTION OF THE INVENTION The object of the present invention is to recover substances suspended in either fresh water or saline water together with other substances normally dissolved therein. related to new ships. The most important product to be recovered from economic and ecological implications is oil. -black tide flt,
(blacktld・)'O1! The elephant is well known to everyone. The technological and economic efforts that have been made to date to solve the problem have not yet yielded satisfactory results; as of now, the world's known oil reserves have been around for approximately 40 years. The fact that it will eventually be used up is already well known and need not be emphasized again. The price of crude oil is rising at an accelerating rate, impacting the cost of manufacturing virtually every type of product that often includes (directly or indirectly) an energy component in determining its total cost. At present, society is not equipped to meet its energy needs with sources other than oil. Therefore, all countries of the world have an extremely serious interest in the recovery of oil spilled into the sea, which arises from various circumstances such as collisions, cleaning of oil tanker hulls, etc. Water pollution caused by spills of oil, petroleum, and other liquids that have a lower specific gravity than water and remain suspended on the water surface is even more serious.

The invention, of which this specification is constructed as an integral part, consists primarily of two quite separate items of equipment.

a) Liquid-liquid separator for recovering products of low specific gravity (petroleum, oil, etc.); b) Device for removing solids from water.

As an aid to the description, there is attached hereto a drawing illustrating, without limitation, one embodiment of a vessel for recovering ore, waterborne materials, as claimed herein. There is.

Components with reference symbols in the figure correspond to the following partial description; the inlet 1 enters the water-oil mixture and any solids are retained in the grid 2, part of this grid line arrangement b) The base consists of a plate with vertical slots.

A specially shaped suction pipe delivers the mixture to the suction means 3, which can be a pump, a reversing liquid compressor or the like. The mixture passes through the butterfly tube 4 and is sent to the settling tank 5 in continuous and intermittent treatment, and the tank is filled with a well-known 170-lens box (F1orent1n@ves@el)' j
The tank may be any other type of liquid-liquid separator/Q-rake, etc., suitable for the purpose. It overflows into the oil storage tank 7 via the oil FAN outlet 6.

Water is pumped out of the last compartment of the separator by a variable flow pump 8, so that the oil level in the last compartment of the separator is maintained constant during the separation process.

The device b) intended for the removal of solids suspended in the water in which a ship is working (which is the subject of the invention) essentially comprises a shovel 9, with the above-mentioned A grid 2 is located and comprises two arms extending in the longitudinal direction of the shovel, these arms being articulated at the end opposite to the one fixed to the shovel, so that the motor can the driven skeleton arm is in an upright position and causes the solids to fall from the shovel in which they are collected (by the eyes of the grid pivoting on its hinges) into a collection receptacle provided for the solids; The collection container is removable so that it can be lifted by a small crane (not shown) for periodic emptying purposes.

The device a) for the separation and recovery of valuable liquids and the removal device b) for solids suspended in the water consists essentially of two suitable floats 1 installed symmetrically longitudinally with respect to the central axis of the ship.
0 and is supported by a frame containing a cross member 11, on which a platform or floor 12 is mounted. The float is attached to the frame by bolts, which allows the float to be expanded and replaced with another float of a different size to adjust the water line level, which level depends on the specific gravity of the water and It is a function of the total weight of the ship and its corresponding equipment in working condition.

Similarly, gearem and equipment of various sizes are provided,
These can be adapted to the floats depending on the surface area of the water to be skimmed, in a manner that favors the working time and thus the final cost.

The ship that is the object of the present invention is powered by its own autonomous locomotive motor, which drives a stern-mounted propeller by means of a transmission, gear changes, and appropriate latches. The ship is also equipped with a rudder, by means of which the ship, together with the above-mentioned equipment, can move in any desired direction at nine speeds suitable for each particular case.

The ship has controls for the above-mentioned equipment, i.e. a), b);
The drive mechanism and rudder are controlled from the cabin 13 located inside.

The cabin has sufficient space and visibility so that the operator has full control and can carry out the various tasks for which the ship is intended. All such variations which do not alter or infringe upon the invention constitute variations within the scope of the invention.

Claims (1)

[Claims] (11) A vessel for recovering substances suspended in water, comprising means for suctioning and separating liquids, said means being combined with means for removing and discharging solids suspended in expanding water; (2) Inhalation of the mixture of liquids and components of the mosquito mixture; the means for separation of the water comprising a device for collecting the liquid mixture by an inlet located at a depth slightly below the free surface of the water;
