Description

Dust recovery system, structure and control device using electromagnet

The present invention relates to a control device for removing a surface floating layer such as oil, a dust recovery system for launching and recovering it, and a structure mediating them.

In the event of an accident in which oil (oil) is spilled on the surface of the sea or lake, it is necessary to promptly take action to prevent the oil from spreading widely.

An oil spill is the release of liquid petroleum hydrocarbons into the environment as a result of unintentional human activity. 'Oil' may be refined oil, including crude oil, refined petroleum products (gasoline, diesel, etc.), or by-products, bunker oil from ships, and oily waste. Oil spills can take months or even years to clean up.

In order to remove such spilled oil, an emulsifier or absorbent is put into the sea, or a removal method using an absorbent cloth or an automated water dewatering device is used.

For example, when performing such a control operation, after installing an oil fence on the circumference of the oil spilled area, the operator throws a square absorbent cloth made of non-woven fabric inside the oil fence so that the oil is absorbed by the oil fence , a method of removing oil by manually collecting the absorbent cloth is used.

However, when the control operation is performed in this way, it is difficult to effectively control the oil distributed over a large area because the absorbent cloth must be accurately thrown into the area where the oil spilled, and the operator must collect the absorbent cloth that has absorbed the oil, There was a problem that the collection took a lot of time.

In particular, in this way, when the worker manually collects the absorbent cloth, the worker is exposed to oil, and in particular, the worker inhales oil vapor evaporated from the oil, resulting in health problems.

Therefore, recently, various marine control devices have been developed and used to solve these problems.

However, since these marine control devices are installed and used on large ships, there are problems in that they are inconvenient to move and difficult to quickly put into the field.

In addition, such an offshore control device requires the driver of the ship to visually check the location where the oil is floating and move the ship to the location of the oil. there was.

In addition, in this way, the control work of controlling the oil floating on the water takes a lot of time. As described above, when the driver visually checks the location of the oil and drives the ship, the driver easily feels fatigued, A problem occurred that preventive work could not be performed continuously for a long time.

In addition to the method using adsorbent cloth, automated oil-water separation methods include weir skimmer, oleophilic skimmer, conveyor skimmer, centrifugal skimmer, and mobile skimmer. And fixed (ship-mounted) skimmers, vacuum skimmers, etc. are known, and all of these devices are installed and used on large ships.

In Korea, an average of 270 oil spill accidents occur annually, and the amount of oil spilled reaches 700,000 L (liter). Most oil spills are small-scale accidents of less than 100L, which account for 70% of the total accident frequency. The problem is that existing automation equipment is all expensive and large equipment, and because different equipment must be used depending on the type of oil, it is mainly used for large-scale oil spill accidents, and all small-scale accidents are made up of conventional labor-intensive absorbent work.

In the process, as described above, industrial accidents such as the smell of oil, headaches, and back pain occur to control workers, and naturally, working hours increase, making it difficult to cope with the first action and increasing the amount of waste.

Therefore, a new method or device for solving these problems is required, and control robots or control equipment having various structures are being developed.

Since these control robots or control equipment are often difficult to move only by manpower, separate equipment is required for launching / recovering (recovery) only.

1A and 1B show a crane device of a forklift structure.

Referring to FIG. 1A, if the control device is launched/recovered (recovered) by using a recovery system having the same structure as a forklift, as the upper and lower guides of the recovery device become longer, the driving area will be limited, and the upper and lower guides Since the entire area is the drive area, the entire area must be lubricated, and when bending of the local portion occurs, the step difference intensifies toward both ends of the upper and lower guides, which may limit the drive area.

Also, referring to FIG. 1B , since the guide must be as long as the height difference from the landing target point, the size of the recovery system increases. In addition, there is an inconvenience in that the use of the case is forced due to the posture instability of the gas (control device) during recovery.

In the event of a marine pollution accident occurring near a port or waterfront, there is a problem in that large cranes or manpower are required to input control robots or control equipment. Depending on the variety of accident areas, it is sometimes difficult to insert heavy equipment.

The existing hydraulically driven skimmer header does not have a self-navigation function, so there is an inconvenience of having to move a crane when moving to an area. To compensate for this, an electrically driven skimmer header is being developed, which is equipped with a self-propelled function and can be moved to the desired area without moving a crane, but a heavy crane is still required to put and retrieve the skimmer header into the sea. However, there is a problem that the ring must be continuously connected to the skimmer header part. If the ring is released to remove the movement restriction of the skimmer header part due to the crane during driving, there is inconvenience that manpower must be put in to reattach the ring when it is retrieved after completion of work in the sea.

The technical problem to be solved by the present invention is to provide convenience when launching / recovering (hereinafter referred to as 'recovery') control robots or control equipment in consideration of these problems.

However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various different forms, only these embodiments make the disclosure of the present invention complete, and common knowledge in the art to which the present invention belongs. It is provided to fully inform the holder of the scope of the invention, and the present invention is only defined by the scope of the claims. Like reference numbers designate like elements throughout the specification.

As mentioned in the background description section, it is difficult to apply the recovery (launch and recovery) system of the forklift structure. On the other hand, FIG. 2 shows an example of applying the crane-structured recovery system to the surface floating layer removal device (also referred to as a control robot or a control device) described in FIGS. 3 to 10 .

As shown in FIG. 2, the crane structure recovery system 100 (hereinafter, also referred to as a crane device) includes a horizontal bar HB and an upper and lower bar VB. The horizontal bar HB does not necessarily extend only in the horizontal direction, and may be slightly inclined or moved such that the angle of inclination changes. And the cable (C) is extended from the horizontal bar (HB) is connected to the control device 10 or the control robot below it. This control device 10 or control robot corresponds to, for example, the hull 10 (water surface floating layer removal device) to be described in detail in FIGS. 3 to 10 .

Hereinafter, details of the control device 10 (water surface layer removal device) will be described with reference to FIGS. 3 to 10 and FIGS. 24 to 30.

And the details of the electromagnetic crane device 100 which lifts this control device 10 are demonstrated through FIGS. 11-23 grade|etc.,.

In the floating surface layer removal device according to the present invention, a contaminated water inlet (20; contaminated water recovery unit) is disposed on the front of the movable hull (10). Behind the contaminated water inlet 20 is a storage unit 40 in which the introduced contaminated water is stored. The contaminated water inlet 20 of the hull 10 and the inside of the storage unit 40 are connected.

Reference numeral 10 denotes a control device 10, a surface floating layer removal device 10, and a hull 10 in some cases, which have almost the same meaning. When explaining the device itself, the expression of the floating layer removal device 10 or the hull 10 was mainly used, and the expression of the control device 10 was mainly used as the object to be lifted by the crane, but a significant difference in meaning does not exist.

In a state in which the sean body 10 is floating on the water surface, the water surface is within the height range of the inlet 21, so that contaminated water can flow in as the hull 10 advances, and this inlet 21 can float in the contaminated water. A filtering means 22 is included to prevent the ingress of oversized solids.

The impellers 30-1 and 30-2 are means for moving the hull 10 of the device back and forth. Although two are shown, the number can be adjusted as needed.

The impellers 30-3 and 30-4 are means for moving the hull 10 of the device left and right. Also, although two are shown, the number can be adjusted as needed.

The outlet 50 (discharge unit) is a portion through which oil is separated from the introduced contaminated water and remaining water is discharged. In FIG. 4, the discharge port 50 is located at the lower part of the hull 10, but may be disposed at the rear side, at the bottom of the rear side, or at the rear side of the lower surface, if necessary.

The filtering means 22 is visible in the front and the impeller 31 behind it. The entire surface of the impeller 31 is not visible, and the upper part is slightly covered with an anti-splash film 32.

And, below, the aforementioned forward and backward impellers 30-1 and 30-2 are shown.

Also here, below the drawing, the aforementioned impellers 30-1 and 30-2 for forward and backward movement are shown.

The contaminated water inlet 20 (contaminated water recovery unit) is visible on the right side of the drawing, and since it is viewed from above, structures such as the filtering means 22, the inlet 21, and the impeller 31 are hard to see.

In addition, the storage unit 40 is shown, and both outer walls (left and right of the hull) of the storage unit 40 may include buoyancy bodies that provide buoyancy. Buoyancy may be provided from the left and right sides of the storage unit 40 or may be provided from the lower side of the storage unit 40 . It would be desirable to provide some buoyancy on both the left and right sides and the lower side of the reservoir 40.

As for the degree of buoyancy, it is appropriate for the impeller 31 to be half submerged. Half doesn't mean exactly 50%, it could be 40-60%. In some cases, it may be 30-70% submerged. Thus, the contaminated water appropriately moves toward the storage unit 40 inside the hull 10 due to the action of the impeller 31 half submerged in water.

Of course, all of the impellers 30-1, 30-2, 30-3, and 30-4 that exert propulsive force for forward and backward movement of the hull are submerged in water. Only the inlet impeller 31 disposed near the inlet 20 is submerged in about half of the water surface.

The contaminated water inlet 20 (contaminated water recovery unit) is shown on the right side of the drawing, and impellers 30-1, 30-2, 30-3, and 30-4 can be confirmed.

The contaminated water inlet 20 (contaminated water recovery unit) is shown on the right side of the drawing, and the sidewall of the storage unit 40 and the impellers 30-2, 30-3, and 30-4 can be confirmed.

The contaminated water inlet 20 (contaminated water recovery unit) is shown on the left side of the drawing, and the sidewall of the storage unit 40 and the impellers 30-1, 30-3, and 30-4 can be confirmed.

That is, at the lower end of the cable C of FIG. 2, there is an electromagnet EM of FIG. 11A caught on a hook. And, when the hull itself of the control device 10 is formed of a magnetic material such as metal, or a magnetic material such as metal is separately attached to the roof of the control device 10, the electromagnet EM of the control device 10 It is possible to lift the control device 10 by contacting the magnetic body (MB) part of the hull. Of course, this is an operation in a state in which the magnetic force of the electromagnet (EM) is activated and turned on.

11b and 11c show a state in which the magnetic material MB is lifted onto the electromagnet EM. 11b and 11c, only the magnetic body (MB) is shown without the control device 10, but this is for testing, and the magnetic body (MB) is attached to the control device 10 through fasteners such as screws or welding, or It will be appreciated that they are fastened via cables/chains or the like. Alternatively, as described above, it is also possible when the hull itself is a magnetic material such as metal.

The control device (hull 10) and the magnetic body MB are fixed to each other through screws, welding, or the like, or through cables. And the electromagnet (EM) is connected to the cable (C) of the crane device 100 of Figure 2 through a ring or the like (see Figure 11a).

Through the electromagnetic crane device 10 configured as described above, the electromagnet (EM) can lift the control device 10 (exactly, the combination of the control device 10 and the magnetic material (MB)).

In the left drawing of Figure 12b, if the upper surface of the magnetic body (MB) attached to the top of the control device 10 is concave shape, there is an advantage that it is easy to combine with the electromagnet (EM) having a convex shape when the lower surface. However, due to the nature of the control device 10 used in the presence of water, when the concave part of the magnetic body (MB) is filled with water, the electromagnet (EM) and the magnetic body (MB) are not well coupled by the magnetic force (磁力) or the combination Even if it does, there may be problems such as weakening.

Therefore, as shown in the right drawing of FIG. 12b, it is preferable that the top surface of the magnetic material (MB) attached to the top of the control device 10 has a convex shape. In this case, the lower surface of the electromagnet EM may have a concave shape to contact the upper surface of the magnetic material MB.

This is an example, and it is also possible that the upper surface of the magnetic material MB is generally convex with a flat surface in the center, and the lower surface of the electromagnet EM is also generally convex with a flat surface in the center. In this case, it is because the flat surfaces of the center are in contact with each other and the control device 10 can be lifted. However, as shown in the right drawing of FIG. 12B, it will be advantageous to secure mutual bonding force if the shapes of the magnetic material MB and the electromagnet EM are complementary to each other.

In FIG. 2, the recovery system 100 (crane device) is only schematically shown, but FIG. 13 shows a specific example thereof. 13 (a) shows a state in which the dust recovery system 100 stores and moves the control device 10, and FIG. 13 (b) shows the dust recovery system 100 raising and lowering the control device 10 It shows the state at the time (however, the illustration of the cable is omitted).

In (b) of FIG. 13, the cable is omitted from the drawing. The recovery system 100 includes a vertical bar (VB), a horizontal bar (HB), an integrated control control panel (CP), a winch (W), and support legs (100-1, 100-2, 100-3, 100-4 , 100-5).

The support legs 100-1 to 100-5 may be referred to as supports in a broad sense.

Referring to (b) of FIG. 13 , the length of the horizontal bar HB may be adjusted in several stages.

In (b) of FIG. 13, the support legs 100-1 to 100-5 stand on the ground or the bottom of the mother ship, and the control device 10 is launched into the water or is about to be recovered from the water. . At this time, the lower ends of the support legs 100-3 and 100-4 extend downward to support the weight of the recovery system 100, and when the support legs 100-3 and 100-4 support the weight, Free movement is restricted by the wheels of the legs 100-1, 100-2 and 100-5. Support legs 100-3 and 100-4 are not essential elements. However, it is preferable that the support supports the dust recovery system 100 at at least three locations (eg, 100-1, 100-2, and 100-5).

13 (a) shows a state in which the control device 10 is coupled to the dust recovery system 100 and moves. Although the coupling state is not shown in detail, the side and / or bottom of the control device 10 may be coupled by being fastened to or strung on the recovery system 100. That is, there is a concave or convex structure in the control device 10 so that this structure is caught in the portion between the support leg 100-1 and the support leg 100-2 of the recovery system (ie, the receiving part). desirable. Concave or convex structures and hooking parts are not shown, but any structure is possible as long as it can withstand the load of the control device 10. Alternatively, it is also possible that the dust recovery system 100 is coupled to the bar 10-B located at the upper end of the control device 10.

Through this structure, the recovery system 100 does not function only as a lift, but can also be used for moving the control device 10. In the form of FIG. 13 (a) for moving the control device, the lower end of the support leg (100-3, 1004) is higher than the bottom of the wheel, and therefore can be easily moved only with the wheel.

Movement by wheels is also possible through a motor, and a form in which a person manually pushes the recovery system 100 is also possible.

14 is a view showing the structure shown in FIG. 13 in more detail.

In (a) of FIG. 14, there is a joint between the vertical bar (VB) and the horizontal bar (HB), and the angle of the horizontal bar (HB) with respect to the ground may be changed according to the movement of the joint. In addition, a winch (W) is installed at one end of the horizontal bar (HB), the cable extends along the horizontal bar (HB) to the other end of the horizontal bar (HB), and the cable extends downward from the other end to the electromagnet ( EM) is connected.

An integrated control panel CP having, for example, a display screen is applied near the joint where the vertical bar VB and the horizontal bar HB meet. Through this control panel (CP), movements (angle adjustment of the horizontal bar (HB), length adjustment of the horizontal bar (HB), whether or not the control device 10 is accommodated, cable winding of the winch, on/off of the electromagnet, horizontal, etc. ) is desirable to be able to control all of them. Whether the control device 10 is accommodated is a mode in which the control device 10 is stored and moved as shown in FIG. 13 (a), or a mode in which the control device 10 is advanced / retrieved as shown in FIG. 13 (b) It refers to determining the recognition, using the cable (C) and the electromagnet (EM) to control the control device 10 in the receiving part (between the first support leg 100-1 and the second support leg 100-2) You can use a method such as placing it on and fixing it by hanging it somewhere. Alternatively, it is possible to designate the position of the ash recovery system 100 through fine adjustment by moving the wheels of the ash recovery system 100 through the control panel CP. That is, the wheel can be moved manually by a person pushing it, or it can be moved through the control panel CP. It is preferable that the motor of the winch (W) or the motor linked to the wheel can be driven with a small amount of power by using a gearbox applied thereto. For example, since the winch W is driven by 24V, the overall efficiency of the recovery system 100 becomes better when the electromagnet EM, the control panel CP, and the driving motor are all driven by 24V.

This is somewhat different from the embodiment shown in FIG. 13 . That is, since the support legs 100-3 and 100-4 shown in FIG. 13 are omitted, a similar effect can be obtained through a simpler structure.

In this case, due to the absence of the support legs 100-3 and 100-4, the fixing force to the ground (or the bottom of the busbar) may be somewhat weakened, and it is difficult to move while the control device 10 is housed. Although there are disadvantages, there is an advantage that the structure is simple and the work and manufacturing are easy.

16A shows a model of the recovery system 100 shown in FIGS. 15A and 15B.

16B and 16C show how the dust collection system of FIG. 15A actually lifts (a model of) the control device 10.

Referring to Figures 16b, 16c, you can see another example of the way the magnetic material (MB) to be attached by magnetic force to the electromagnet (EM) coupled to the control device (10).

As shown in Figure 16b, the magnetic material (MB) magnetically attached to the electromagnet (EM) does not necessarily have to be in surface contact with the upper surface (ie, roof surface) of the control device (10). That is, it can be seen that the approximately plate-shaped (even if somewhat concave or convex, even if completely plate-shaped) magnetic material (MB) is coupled with the control device 10 through a plurality of separate cables (C2). In this case, the roof surface of the control device 10 does not necessarily have to be metal, and even if it is not metal, it does not necessarily have to be a hard object. For example, the roof surface of the control device 10 may be made of a thick vinyl material, and four flexible cables C2 or chains may be connected to the four corners of the control device 10. In this case, the magnetic material (MB) is placed on the roof surface made of vinyl material, and when the electromagnet (EM) is attached to the magnetic material (MB) with magnetic force and lifted, the combination of the electromagnet (EM) and the magnetic material (MB) is lifted and the magnetic material (MB) is lifted. A space is created between the (MB) and the roof surface, and the entire control device 10 will be lifted as the cable (including the chain type) is tensioned. In this example, there are four separate cables (C2), but three or more will suffice.

The connection between the magnetic body (MB) and the cable (or chain) (C2) may use a ring, and may also use a ring for the connection between the cable (or chain) (C2) and the control device (10).

17A and 17B show a magnetic body attachment part of another embodiment.

16b and 16c, the magnetic material (MB) was attached to the control device 10 through the cable (C2) or chain, but in FIGS. A plurality of extending fixing members FM are shown.

In FIG. 17A, the side surface of the magnetic body MB is substantially vertical in an unfinished state, but in FIG. 17B, a member having an inclined surface is attached to the side surface so that the magnetic body MB is convex upward as a whole (right side of FIG. 12B). as in the magnetic body (MB) in the drawing). The central surface of the magnetic material MB shown in FIG. 17B is flat, and a black inclined plane member is attached to its circumference, so that it is convex upward as a whole, which corresponds to the one shown on the right side of FIG. 12B.

18 shows an electromagnet (EM) and a magnetic body (MB) of another embodiment.

The magnetic material MB shown in FIG. 17B has the same shape as the right drawing of FIG. 12B, but the magnetic material MB shown in FIG. 18 has a concave top surface, so it may look similar to the magnetic material MB shown in the left drawing of FIG. 12B at first glance. can However, in the embodiment shown in FIG. 18 , it can be seen that a plurality of grooves Gr for drainage are formed in the magnetic material MB. Therefore, even if the upper surface is concave, water does not accumulate in the concave portion. This may be an integral structure, or an additional structure may be added to the top of the magnetic body MB shown in FIG. 17B to provide a magnetic body MB having a structure as shown in FIG. 18 .

On the other hand, if the magnetic material MB has a structure as shown in FIG. 18, the electromagnet EM preferably has a downward convex structure as shown in FIG. 18 thereof. This is to perform accurate and stable lifting by combining with the concave part of the magnetic material (MB).

In particular, the electromagnet EM may be modularized. Advantages of this case are explained using FIG. 19 and the like.

19 shows a modularized electromagnet (EM).

The modularized electromagnets EM shown in FIGS. 18 and 19 are convex downward, but whether they are convex/concave may be determined as needed. The electromagnets EM shown in FIGS. 18 and 19 are modularized, unlike those shown in FIG. 11A, and are modularized by integrating, for example, a battery, an inverter, and a control circuit. That is, the electromagnet (EM) and the electrical part for driving it are simplified and modularized, and through this, the electromagnet (EM) can be easily utilized in the recovery system 100 (crane device).

In the modular electromagnet of the present invention, the electromagnet is a part of the dust recovery equipment 100 and is used in combination with a crane. Instead of installing a battery, control box, inverter, etc. in the existing crane and connecting wires to the electromagnet with wires, the electromagnet is modularized so that the electromagnet can operate independently without external cables and control boxes.

20a and 20b illustrate modularization in terms of weight.

When the battery, the inverter, and the control unit are separately installed, for example, as shown in FIG. 20A, the battery weighs 21.32 kg, the inverter weighs 3.80 kg, and the control unit weighs 3.48 kg, resulting in a total weight of 28.6 kg. This does not include the weight of the electromagnet itself. If this is modularized, it becomes 7.84 kg as shown in FIG. 19b (14.5 kg of the weight of the electromagnet itself is subtracted from the measured 22.34 kg).

21A and 21B illustrate modularization in terms of cost.

Of course, it depends on what specifications are made, but the cost required as an example is as follows.

For example, if a lithium ion pack, an inverter, and a controller for removing residual magnetism are separately purchased as shown in FIG. 21A, they cost 2.2 million won, 336,600 won, and 984,500 won, respectively, for a total of 3,521,100 won (excluding the electromagnet). ).

If this is integrated as shown in FIG. 21B, a total of 159,500 won is required, which is 5,500 won per regulator (x2), 12,000 won per BMS (x3), and 2,850 won per 18650 cell (x36) (excluding electromagnets). .

The electromagnet itself costs about 1.9 million won in both cases.

22 shows a state before the electromagnet EM is modularized.

23 shows a state after the electromagnet EM is modularized.

In FIG. 22 , the battery, control unit, electric wire, etc. are connected from the lower end of the recovery system to the horizontal bar HB via the vertical bar VB. In addition, although not shown, since the wire must be connected to the electromagnet EM, wiring may be complicated and use may be inconvenient.

On the other hand, the modularized electromagnet of FIG. 23 does not require shipment of additional equipment as shown in FIG. 22 and does not require cable connection to the electromagnet (wireless use), so it is much freer in terms of the use environment. 23 is a state in which the upper cover of the electromagnet module is not covered, and when the upper cover is covered, the shape is the same as the upper right corner of FIG. .

That is, the electromagnet module can be controlled by wireless communication such as Bluetooth in a mobile device such as a smart phone. Through electromagnet modularization and a simple remote operation method, anyone can use it easily without restrictions in the environment. The control device may be a smart phone, or may be a control panel (CP) shown in FIGS. 13 and 14 as another example.

In the above, the dust recovery system 100 (crane device) has been described in detail with reference to FIGS. 2 and 11 to 23 .

Hereinafter, in FIGS. 24 to 30, the pest control device 10 (water surface floating layer removal device), which is an object of lifting by the ginseng recovery system 100, will be further described.

24A is a cross-sectional side view of the vicinity of the inlet 20.

In FIG. 24a , a pipe 33 surrounding the impeller 31 is shown, and it can be seen that the inlet 20 and the storage 40 are connected through the pipe 33 . For convenience of description, illustration of the filtering means 22 is omitted.

The impeller 31 is a structure for inflow (recovery) of contaminated water, which may operate in connection with the motor 31M.

The position of the motor 31M shown in FIG. 24A is an example, and other positions are also possible.

The impeller 31 is to introduce (recover) contaminated water, but in other words, it can be explained that the oil on the sea level is pushed down and sent back. In this case, the closer the impeller 31 is to the recovery start point, the faster the contact between the effluent oil and the impeller 31 on the front of the hull 10 is possible and the recovery speed is improved.

That is, when the hull 10 moves forward and recovers the effluent oil (contaminated water), in order to suppress the occurrence of stagnation of the inflow (ie, seawater + effluent oil) in the impeller housing 33 (pipe), the impeller 31 and the impeller housing 33 are moved forward and the unnecessary front part is removed, thereby solving the congestion phenomenon. From this point of view, the inflow efficiency of the form of FIG. 24a may be better than that of FIG. 24b, which will be described later.

24B is a diagram showing an embodiment different from that of FIG. 24A.

FIG. 24B shows that the inlet 20 and the storage 40 are connected through a pipe 33, and the configuration in the large frame is similar to that described in FIG. 24A.

In FIG. 24B , the filtering means 22 is shown, and unlike FIG. 24A , a motor 31M for operating the impeller 31 is disposed above the filtering means 22 . The location of the motor 31M can be changed in consideration of weight distribution, thickness and shape of the hulls 10 and 10'.

Also, in FIG. 24B, the position of the filtering means 22 is moved further inward (rear side of the hull) compared to that in FIG. 3. This can also be changed in consideration of weight distribution, thickness and shape of the hulls 10 and 10'.

In FIG. 24B, the recovery starting point is indicated by a dotted line. In this case, since the distance between the recovery start point and the impeller 31 is long (compared to the case of FIG. 24A), the inflow efficiency may be somewhat low.

On the other hand, in FIG. 24A, since the recovery start point (dotted line) is near the impeller 31, the recovery efficiency may be higher. Of course, if the filtering means 22 (see FIG. 3, etc.) is omitted as shown in FIG. 24A, the recovery efficiency will be the best. may be That is, modifications such as omitting the filtering unit 22 or installing it closer to the impeller 31 (closer to that shown in FIG. 3) will be possible, if necessary.

Of course, although the form of FIG. 24a has better contamination water inflow efficiency than the form of FIG. 24b, both the form of FIG. 24a and the form of FIG. 24b are included in an embodiment of the present invention.

25A is a more simplified view of the inlet 20 compared to FIG. 3 .

In FIG. 25A, the filtering means 22 is omitted compared to FIG. 3, and it can be understood that the impeller 31 is omitted only as a drawing in order to make it more visible, and if necessary, the filtering means 22 is actually It is okay to increase the inflow efficiency by not installing it.

In FIG. 25A, an anti-splashing film 32 is installed on the upper front portion of the impeller 31.

25B is a partially enlarged view of FIG. 25A.

Although not shown in the drawing, the buoyancy of the hull 10 is adjusted so that the surface of the water is about the middle of the impeller 31. That is, water is not submerged above the rotational axis of the impeller 31, and water is submerged below the rotational axis.

At this time, the impeller 31 introduces the contaminated water and sends it toward the storage unit 40, and the inflow water may splash out near the top of the water surface (ie, the upper half of the impeller). In order to prevent this, a part of the upper end of the inlet side of the pipe 33 (impeller housing) in which the impeller 31 is installed is covered with an anti-splashing film 32. This prevention film 32 serves to prevent the inflow water introduced into the impeller housing 33 from being splashed outward (ie, in the +X direction) by the impeller 31 . Through this operation, the efficiency of inflow (recovery) of oil-water (contaminated water) can be increased.

That is, when the impeller 31 rotates, water splashes in the front of the hull 10, resulting in a problem of spilled oil being pushed. To solve this problem, 20 to 30% of the top of the inlet of the impeller 31 By combining the anti-splashing film 32 with the degree, the spilled oil diffusion problem present in the front of the hull 10 is solved. The above 20 to 30% is a preferred example, and may be blocked up to 40 to 50% if necessary.

The impeller housing 33 is also shown in a cross section cut in half, and the impeller 31 is accommodated therein. Two impellers 31 and two housings 33 are shown, but the number can be changed as needed, but compared to the case of one impeller 31 and one housing 33 (FIG. 26b described later), In the case of two as in 26a, the efficiency of running water inflow will be better.

As described above, FIG. 26B is different from FIG. 26A or FIG. 3 in that the inlet part has one impeller 31. In the case of FIG. 26B, there is no problem at all in the operation, however, the inflow efficiency may be slightly lower than in the case where the number of impellers 31 is large as in FIG. 26A.

27A is a diagram showing the storage unit 40.

In the drawing, the inlet 20 is shown simplified without impeller 31 or impeller housing 33.

The introduced contaminated water passes through the flow shown by the arrow in the drawing.

As the contaminated water moves to the back of the storage unit 40, it is separated into a low-density part (oil) contaminated by oil and a high-density part (water) that is not contaminated by the density difference. The part is discharged through the discharge part 50 disposed at the lower end of the storage part 40 (or the rear lower part of the storage part 40), thereby enabling purification of contaminated water.

When the contaminated water moves in the storage unit 40, the longer the transfer time is, the more effectively the separation into the contaminated part and the non-contaminated part can occur. It is important.

To this end, it may be considered that the above-described vertical partition walls V0 to V4 are disposed in the storage unit 40 as baffles to increase the movement time of contaminated water.

As the contaminated water passes through the baffle plate (baffle), the movement distance increases as a result, and the movement time increases accordingly, so that the contaminated water and the non-contaminated portion can be more effectively separated by the difference in density. Where the baffle plate comes into contact with the side surface of the storage unit, through-holes may be disposed as necessary to effectively prevent stagnation of contaminated water.

27A, there are several vertical barrier ribs (V0, V1, V2, V3, V4). The vertical bulkhead V0 has an opening at its lower end. As a result, based on the lower right picture of FIG. 27A , it can be seen that water flows across the vertical bulkhead V0 like an arrow.

Further, as shown in the upper right corner of Fig. 27A, the vertical partition walls V1 to V3 have an opening in the middle. Through this opening, it can be seen that water flows across the vertical bulkheads V1 to V3 like an arrow, based on the lower right picture of FIG. 27A.

As it passes through several vertical partition walls (in particular, V1 to V3), a flow is formed at a low flow rate.

The vertical bulkhead V4 has an opening at its lower end. As a result, it can be seen that water flows across the vertical bulkhead V4 like an arrow, based on the lower right picture of FIG. 27A.

Of course, the shapes of the illustrated vertical partition walls V0 to V4 are examples, and are not necessarily limited to those illustrated.

Oil spilled particles of a certain size or larger included in the contaminated water float on the sea surface because the floating speed is faster than the discharge speed, but oil spilled particles of a certain size or smaller are more affected by the discharge flow and are discharged to the outside of the hull (10). may be released. Therefore, the floating time is secured through the vertical bulkheads (V1 to V3) so that spilled oil particles of a certain size or less can float more easily.

Through several vertical bulkheads (V0 to V4, in particular, V1 to V3), a circular vortex is formed between the bulkheads to form a structure so that the spilled oil can join near the sea level.

Somewhat different from the drawing, a filter structure in which the vertical partition walls V1 to V3 have a mesh may be used.

Of course, some are walls and some are filters.

Further, the vertical partition walls V1 to V3 may be a specific gravity difference filter capable of separating water and oil.

And, in FIG. 27A, there is a horizontal partition wall H1.

The horizontal bulkhead H1 is a structure installed to filter out spilled oil particles that could not float even through the vertical bulkheads V1 to V3.

That is, in the lower right picture of FIG. 27A, the overall flow of water is indicated by arrows, and at the end, it can be seen that four small arrows pointing downward are directed toward the horizontal bulkhead H1. In this horizontal bulkhead (H1), fine oil particles are filtered and prevented from being discharged downward.

The water passing through the horizontal bulkhead H1 is discharged through the outlet 50.

FIG. 27B is a diagram illustrating another embodiment of FIG. 27A.

Figure 27b is almost similar to Figure 27a, but there is a slight difference in the number of vertical bulkheads or the height of the inlet. Nevertheless, the principle of operation is substantially the same. In addition, the horizontal bulkhead H1 filters fine oil particles.

The horizontal bulkhead H1 may be slightly separated from the discharge port 50 as shown in FIG. 27A, or adjacent to the discharge port 50 as shown in FIG. 27B.

As shown in FIGS. 28A and 28B , the horizontal bulkhead H1 may be multi-layered, or may have slightly different shapes, or may be provided with a support rim or a support center line as necessary.

By selecting a mesh size (eg 100 mesh, eg 80 to 120 mesh) that does not affect the recovery rate (eg 400 L/min, eg 350 to 450 L/min), the oil particles ( That is, fine oil particles) can be filtered.

Also, in FIGS. 27A and 27B, the vertical barrier ribs V1 to V3 are described as a material with holes, but it is also possible to form the vertical barrier rib using the material of the horizontal barrier rib H1 shown in FIGS. 28A and 28B. In this case, the recovery rate or mesh size may not necessarily be the same as that of the horizontal bulkhead.

29B is a cross-sectional view of FIG. 29A.

Although the appearance of the hull 10 is somewhat different from FIG. 3 and the like, the operation principle is largely the same. 29a and 29b, bilge keels (Bilge Keels; BK1 to BK4) are installed on the front, rear, left and right sides of the hull 10.

According to FIG. 29C, it can be seen that, for example, installing bilge keels (ie, BK1, BK2) on the left and right sides has a greater effect of reducing shaking than when bilge keels are installed on the left and right floors (ie, below). can

In addition, it can be seen that installing a bilge keel (ie, BK3) on the front has its own effect.

Based on these experiments, bilge keels (BK1 to BK4) were installed in the same positions as shown in FIGS. 29a and 29b.

29d shows the results according to the presence or absence of bilge keel.

Compared to no bilge keel, pitching is reduced by 53% in sea level situation level 1, pitching reduced by 37% in sea level situation level 2, and safe even in sea level level 3 (wave height 1-1.25 meters). It can be seen that operation is possible.

The vertical barrier rib does not necessarily have to have the same shape as the vertical barrier ribs V0 to V3 of FIGS. 27A and 27B, and may have the same shape as the vertical barrier ribs VW1 to VW11 of FIG. 30A.

The vertical bulkheads V0 to V3 in FIGS. 27A and 27B have a space (opening) below or an opening in the middle. Of course, it is not limited thereto, and, if necessary, there may be an opening at the top, an opening at the bottom, an opening at both the bottom/above, or an opening in the middle.

Similarly, the bulkhead of FIG. 30A may have an opening at the top, an opening at the bottom, an opening at both the bottom/above, or an opening at the middle. In addition, as shown in FIG. 30A, even a wedge shape when viewed from above can form a water flow path suitable for oil-water separation.

(a) shows a horizontal baffle (winged baffle). The baffle has the same meaning as the aforementioned vertical/horizontal bulkhead.

Horizontal baffles are highly effective for up-and-down flow (hill driving, pitching).

The optimal position is more effective when slightly more submerged than on the free surface.

In addition, the effect is excellent near the surface of the water and rapidly decreases as it goes below the surface of the water.

In addition, the optimal length is 10% of the tank width (based on one side), and even if it is longer, there is almost no increase in effect. For example, it may be 7-13% of the tank width. As shown in (a) of FIG. 30B, it may occupy about 10% of the length on the left side of the water flow and about 10% on the right side of the water flow.

The figure in (a) shows the numerical value (ratio) based on the tank width.

As an example of the optimal length, one 9.4% (eg, 0.08 m) may be installed on the left side and another 9.4% may be installed on the right side.

The optimum height is 90% of the water level (when the distance from the bottom to the water surface is 100%). For example, it may be 85 to 95%.

(b) shows a vertical baffle (diaphragm type baffle).

This is highly effective for left and right movement (corner driving, rollover).

It has to be extended to the free surface (water surface) to be effective, and if it is higher, it has little effect.

The optimal length is 76% of the total height (eg, 0.19 m). For example, it may be 70-85%.

(c) shows a vertical baffle (diaphragm type baffle).

There was no significant relationship with the optimal depth. Near the free surface (water surface) is considered optimal, but the difference is not large.

The optimal length was about 44% of the height from the bottom of the tank to the water surface, and there was little increase in the effect even if it was longer. For example, it may be 40-55%.

In summary of (a) to (c), driving stability is secured by using vertical/horizontal bulkheads to suppress the flow of internal spilled oil and seawater.

It is good to set the horizontal bulkhead area corresponding to 10% of the left and right width of the oil recovery device, and to set the horizontal bulkhead position at the part corresponding to 90% of the water level standard (direction close to sea level) in the oil recovery device.

As the contaminated water moves to the back of the storage unit 40, it is separated into a low-density part (oil) contaminated by oil and a high-density part (water) that is not contaminated by the density difference. The part is discharged through the discharge part 50 disposed at the lower end of the storage part 40 or the rear lower part of the storage part 40, so that the contaminated water can be purified.

To this end, baffles (baffles) for increasing the movement time of contaminated water are disposed in the storage unit 40 as the aforementioned vertical partition walls V0 to V3 or VW1 to VW11. For example, the baffle plate may have a wedge shape fixed to both the upper and lower portions of the storage unit 40 and facing the connection unit 30 . Of course, as described above, it may be another example that is a certain distance from the top and bottom.

Buoyancy devices are disposed on the left and right sides of the hull 10, which may be hollow and watertight tubes made of metal or non-metal. An additional buoyancy device is required to impart buoyancy to the hull 10 because the discharge unit 50 is disposed at the bottom of the main body of the storage unit 40 and cannot impart buoyancy to the hull 10. These buoyancy devices are placed on the left and right so as not to affect the forward and backward directions of the hull (10). The storage unit 40 shown in FIG. 1 may be configured to serve as a buoyancy device at its left and right ends (ie, there is a buoyancy device not shown at the left and right ends inside the storage unit 40 of FIG. 3), , A buoyancy device may be attached to the outside of the storage unit 40 shown in FIG. 3 .

Although the embodiments of the present invention have been described with reference to the accompanying drawings, the present invention is not limited to the above embodiments and can be manufactured in a variety of different forms, and those skilled in the art in the art to which the present invention belongs A person will understand that the present invention may be embodied in other specific forms without changing the technical spirit or essential features. Therefore, the embodiments described above should be understood as illustrative in all respects and not limiting.
