Description

Collector for oil collectors {COLLECTING APPARATUS FOR AN OIL COLLECTOR}

The present invention relates to a collecting device for an oil collector, and more particularly, to be fixed to an oil collector floating in water to improve the collection efficiency of the collecting device.

Float supported collectors are known, which has the problem that large amounts of water are collected with the oil. In summary, such a collector consists of an oil transfer pump having a funnel that is open upwards, the collecting inlet of which is located below the water surface. The collection inlet should be located as close to the water surface as possible. Since the funnel's open collecting inlet is located below the water surface, the amount of oil collected becomes very small relative to the amount of water as the wave actually rises. Subsequently, attempts were made to provide collectors with additional structures, but the results were negligible.

Furthermore, a floating oil pick-up mechanism which is supported on a float and lifts oil out of water via a rotating disk for recovery is known, for example in US Pat. No. 4,021,344. However, this known solution has the disadvantage of being complicated. To rotate the disks, teeth need to be provided at the edge of each disk. The teeth machined into the rotating worm ring engage in a horizontal direction with the teeth of the disk, thereby making these disks a desirable rotational motion. This construction places high demands on the material of the disc and the worm ring. In addition, one of the teeth may be disturbed by debris floating in the oil, so that all devices may be stopped immediately.

It is an object of the present invention to solve the above-mentioned problems and to provide a collecting device which is simpler in structure than before and more reliable in operation, for example, which can be mounted on an existing collector. This is achieved by a collecting device according to the attached independent claim 1.

The solution of the present invention is that, when the central portion of the collecting member is made of a flexible material and formed into a ring-shaped endless shaft shape, it is very simple and provides a reliable structure for operation related to oil collection. Based on the concept Thus, a ring of collecting members provided with bristles can be formed by fixing the bristles directly in the center of the collecting member, and in the case of using a collecting plate as an alternative, the collecting plate can be fixed directly to the center of the collecting member. Thus, the bristles and the collecting plate rotate directly together with the center of the collecting member, and this rotation does not require teeth that can be disturbed by debris in the oil. In the present invention, the parts (e.g. teeth) required to rotate the center of the collecting member require very little space and are therefore easy to surround.

By using the ring-shaped collecting member, it is possible to obtain the advantage that oil recovery can be carried out on all aspects of the collecting device, so that the recovery is efficient. By mounting the collecting device of the present invention on a known funnel type oil collector, the operating efficiency of the collecting device is significantly increased because more oil and less water can be collected.

According to the invention, the central portion may be integrally formed. Alternatively, the central portion may consist of a plurality of members such that both ends may be interconnected, and both ends may be interconnected via motor (s) that rotate the central portion. An appropriate rotation ratio may be achieved by using a reduction gear between the motor and the center.

Preferred embodiments of the collecting device according to the invention are disclosed in the attached dependent claims 2 to 6.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1A is a diagram illustrating how the collection device according to the present invention is secured to an oil collector, and FIG. 1B is a view showing a collection device mounted to an oil collector.

1A and 1B, the collecting device of the present invention is arranged on the frame 1 and is embodied to be mounted to a funnel 8 of a known floating oil collector. In FIG. 1A, the motor (s) 4 and the collecting member 5 are fixed to the frame 1 in the mounting base 2 surrounding the central opening 6. A float 10, an oil transfer pump 9, an oil transfer hose 12, and an oil receiving vessel 11 are fixed to the funnel 8.

In FIG. 1B, the frame 1 and associated parts are secured to the funnel through the mounting base 2. In FIG. 1B, the collecting device is suspended in water such that the collecting member 5 is located at the water line VL.

The present invention utilizes a frame (1) surrounded by a flexible central portion of the collecting member (5), and the longitudinal axis of the central portion is adapted so that the central portion of the collecting member (5) rotates at a predetermined distance from the frame. Dimension is set for. Thus, the central portion acts as a flexible axis. The U-shaped boundary surrounding the central opening 6 of the frame is part of the mounting base 2 of the frame 1, to which a funnel 8, an oil transfer pump and the like are connected. When connected in this way, the U-shaped structure means that the outer boundary of the frame 1 is formed as a groove, which allows the collecting member to be disposed in this groove due to the groove which is opened horizontally outward.

The U-shaped structure of the frame must be adapted to match the U-shaped structure to the collecting member 5 surrounding the central portion, and to fit the mounting base 2 with the funnel 8 fixed to the oil transfer pump 9. The frame 1 also comprises one or more points, in which the central part of the collecting element 5 is equipped with a motor as well as a cleaner for cleaning the collecting element, as well as bearings. The funnel 8 fixed to the oil transfer pump 9 functions to stabilize the receipt of collected oil. In some cases, the funnel may be omitted entirely from the structure, and the mechanism and float 10 fixed to the frame of the collecting device will be fixed directly to the oil transfer pump.

By arranging the collecting member 5 around the circular frame 1, a large collecting capacity can be obtained compared to the size of the collector. The central part of the collecting member 5 must be made of a strong material, such as metal reinforced rubber or similar flexible material. Because of this strong and flexible central structure, it is possible to use a brush suitable as a collecting member for collecting the ignition oil. Although brush technology is the predominant collection method, it is also possible to use the disc as a collecting member if necessary.

The oil collecting device shown in FIG. 1B can be connected to the boat, for example the energy required to drive the collecting member and the energy required to operate the oil transfer pump 9 can be transferred from the boat. Alternatively, the oil collection device may be an independent device provided with the power source necessary to enable the above drive and pumping.

2A is a side view showing a partial cross section of a first preferred embodiment of the collecting device, and FIG. 2B is a top view of the first preferred embodiment.

FIG. 2A is a side view showing a partial cross section of the collecting device, in which the central part 3 of the collecting member 5 surrounding the frame 1, which is part of the mounting base 2, is connected to the motor 4 via the clamp 13. It is fixed. Also shown in FIG. 2A is a bearing 7. Thus, the collecting member 5 has an elongated central part 3 having a central axis, which is formed as a ring-shaped endless axis. This endless shaft is driven by the motor 4 to lift oil out of the water through the collecting member 5.

2b is a plan view of the collecting device, which is installed longitudinally with respect to the collecting member 5 surrounding the frame 1 which is part of the mounting base 2 and the central part 3 rotating on the bearings; It comprises a motor (4) fixed through the clamp (13). A motor installed in the frame in the longitudinal direction of the center 3 can, for example, operate on a bidirectional shaft, to which both ends of the center are fixed via clamps or the like. The longitudinally installed motor in the center makes the collecting member shorter, thus also reducing the collecting capacity, but technically it is not easily damaged when the motor is running in the lateral direction.

3A is a partial cross-sectional view of a second preferred embodiment of the collecting device, and FIG. 3B is a top view of the second preferred embodiment. These figures show how the central part 3 is mounted on the frame 1 via the bearing 7. In this embodiment, the motor 4 is installed in the transverse direction.

This figure shows the side of the support 16 and shows the cross section of the bearing 7 fixed to the mounting base 2 in the frame 1 and the motor 4 installed transversely. This figure shows a cross section of the central portion. A gear 14 is connected to the central portion, and the rotational motion of the motor can be transmitted to the central portion 3 by the gear. The area in which the gear is fixed at the center can be enclosed in accordance with the invention to prevent debris in the oil from entering the gear and hinder its operation.

4b shows a method of fixing a second preferred motor. This figure shows the plane of the mounting base 2 and the cross section of the frame 1, in which the motor 4 and the bearing 7 are fixed, and the gear 14 fixed to the center 3 is also installed. do. In FIG. 4B, the motor is installed in the center 3 in the transverse direction. Therefore, a gear wheel arranged inside the bearing can be used.

5A and 5B illustrate the structure of a cleaner of the collecting device. 5a shows a cleaner and a bearing 7, which is supported by a support 16 fixed to the frame 1 through which the oil is removed from the collecting member 5. 5B is a cross-sectional view of the frame 1 and the cleaner 15, which is mounted on the support 16, through which the collecting member 5 is cleaned. As clearly shown in FIG. 5B, the groove formed by the outside of the frame cooperates with the collecting member 5 provided with bristles. When the oil transferred into the groove by the collecting member comes into contact with the groove, the oil is pushed deeply into the bristles of the collecting member, whereby the oil is raised through the collecting member to the cleaner as efficiently as possible.

If the collecting member 5 is a brush or frame, it is possible to use conventional cleaning methods, for example based on teeth, serrated blades or disks. The cleaner 15 is fixed to the collecting device by, for example, attaching to the support 16 in the frame 1 using a bolt. Despite being curved, the tip of the cleaner 15 follows the curvature of the central part 3 so that the brush of the collecting member 5 is always kept between the tips. This operation is performed so that the motor 4 installed in the frame 1 starts the rotation of the center 3 supported on the bearing 7, in which a collecting member is mounted or fixed. The oil adhering to the collecting member 5 floating on the water surface by the float is removed by the cleaner, which is introduced into the funnel 8 through the central opening 6 or directly into the oil transfer pump. In the pump the oil is pumped into the boat or into a correspondingly arranged oil collection tank.

The attached collecting member 5 is shown. The central portion of the collecting member 5 may be provided with a slide ring 18 at one or more points, the function of which is to prevent the central portion 3 from moving longitudinally and to improve the rotation of the central portion 3. will be. The bearings 7 required in the slide ring 18 can be fixed to the frame by bolts at the desired intervals and must be prepared to be open when the collecting member is replaced. For example, nylon can be used as the material for the slide ring and bearing to reduce the weight of the slide ring and bearing and to improve the resistance to salt water.

6A illustrates the collection member structures alternately arranged with one another, where the collection member may be provided with, for example, an oil collection plate, bristles or a ring of brushes.
