The invention relates to a washing machine specially designed for oil booms.

To date, cleaning the control booms used to control oil spills from adhering oil has been a very laborious and time-consuming delivery. However, such work is not, of course, continuous, but only occurs when oil spills have occurred and control equipment has been used. However, in the event of major damage, up to kilometers of booms have to be used, so cleaning them by hand can be overwhelming for maintenance personnel, or at least too time-consuming. This, of course, means unnecessary costs.

The disadvantage so far has been that there is no suitable machine or device for that purpose.

It is an object of the present invention to provide a washing machine for oil spill booms.

The machine according to the invention has rotating brushes and jets of water and detergent, through which the washable oil spill boom is fed, and the invention is mainly characterized by what is stated in the appended claims. The machine achieves fast and efficient washing results.

A suitable embodiment of the invention is illustrated in more detail in the following description with reference to the accompanying drawings, in which Figure 1 schematically shows an embodiment of a machine according to the invention seen from the side, Figure 2 shows the machine seen from above.

The machine according to the invention has a feed tank 1 at the front end of the machine, i.e. in the left end of Fig. 1, in which the washable oil spill boom 2 is suitably folded on overlapping folds, as schematically shown in Fig. 1. The feed tank can advantageously be made, for example, in the form of a wheeled carriage with a suitably sized space surrounded by mesh or cage walls into which the oil boom can be folded, after which the carriage is taken to the machine.

The machine itself comprises an elongate body 3, which is most preferably made by welding suitable steel profiles. At the front end of the frame, a cylindrical roller 4 or the like is mounted transverse to the longitudinal direction of the machine, over which the washable oil boom is fed into the machine. The roll 4 is coated with a surface layer 61645 which does not slip relative to the boom. In addition, in connection therewith, two, most preferably pneumatic-rubber wheels 5, one near both ends, are arranged above.

The roller 4 is adapted to be mechanically rotatable, either via a suitable transmission by means of a drive motor or a motor built inside the roller in a known manner. The wheels 5 are mounted so that their axis is substantially perpendicular to the longitudinal direction of the machine. Furthermore, the wheels 5 are arranged so that they press against the roller 4 either by spring force or by other load, e.g. weights or a power unit. In this case, the roller 4 and the wheels 5 together form a feed device which pulls the washable oil spill boom inside the machine. The axles of the wheels 5 can be turned so that a small plowing angle can be formed between them so that the wheels are made to pull the oil spill boom slightly to the side, whereby it remains as if tightened laterally. The plowing angle can be adjusted during operation.

The roll 4 is most preferably in two parts 4a and 4b, whereby an empty space is formed between the parts for the floating part of the boom.

After the roller 4, in the direction of travel of the washable boom, a kind of table or slide base 7 is mounted on the machine, on which the washable oil boom slides forward while applying jets of detergent and water to wash away the adhering oil. The base 7 is also in two parts, comprising parts 7a and 7b, between which a gap 8 is left, in which the floating part 2a of the oil boom 2 can slide. The base 7a, 7b is most preferably made of, for example, a stainless steel bar or pipe by bending and welding together, whereby it has a kind of longitudinal slide rails 9, on which the oil boom to be cleaned slides easily. The edge of the base is surrounded by a frame part 10, which on its inner part also forms a slide rail 11, against which the floating part of the oil boom slides, preventing the oil boom from moving laterally during washing. In this case, the floating part 2a of the oil boom 2 remains between the bases 7a, 7b with a suitable clearance, whereby it can move freely in its forward direction.

The part of the base 7a, 7b above the lower brush can also be made to be turned up, so that the washable boom can be easily transported from below the base and during washing the brush presses it against the base.

According to the invention, the machine also has other sliding bases 7 of the above-described shape, on which the oil boom to be washed passes during washing. In addition to this, other traction rollers 4 with counter-wheels 5 are also arranged further in the direction of travel, as described above. The rollers 5 are either single-acting or shared via a chain transmission known per se or other similar transmission, whereby the circumferential speed is made equal for all rollers. In single operation, the drive motors are synchronized with each other to keep the speed the same.

For carrying out the washing, spray nozzles 12 are arranged below and above the sliding surfaces 7 for spraying the washing liquid onto the boom to be washed. Water mixed with a suitable detergent can be used as the washing liquid. In addition, brush rollers 13 are arranged above and below the levels 7, which are rotated by motors and are preferably arranged transversely to the direction of travel of the boom to be washed, so that the brush roll brushes the surface of the boom during washing. At the end of the washing machine there may be a tank or cage 14 into which the washed oil spill boom is assembled and folded and further transported out for storage for the next use. The end edge of the washing machine also has a rotating roller 4, which makes it easier to get the oil boom out of the machine.

The figure shows the machine mainly schematically to illustrate the structural principles. It is clear that the details can be varied in many ways. Most preferably, the machine is fully enclosed, thus preventing the washing liquid from spilling into the environment. Observation windows and hatches can be placed in suitable places, through which potential disturbance points can be accessed.

Claims (3)

5 61645 The machine is provided with a collecting basin for washing liquid and oil dissolved therein, from which the liquid is passed to an oil separator, which may be of a structure known per se. Here, the oil is separated from the washing liquid, which, if purified, can then be discharged into the sewer or reused as a washing liquid. The separated oil can also be utilized in a suitable manner. Patents required: A washing machine, in particular for cleaning oil barriers, after use, the machine comprising a conveyor track or the like fitted with rotating brushes (13) acting above and below the boom and washing liquid spray means (12) to enhance oil removal, thereby driving there are rotating, machine-operated rollers (4) and sliding surfaces (7) between them for conveying the boom past the washing brushes by means of wheels (5) arranged above the rollers with the boom running between the rollers and the wheels, characterized in that the rollers (4) and sliding surfaces (7) ) are in two parts, leaving a space between the parts (4a, 4b; 7a, 7b) for the floating part of the boom and that the axes of the wheels (5) can be turned horizontally so that a so-called plowing angle, so that the boom to be washed remains suitably tight even laterally.
