DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oil spill recovery apparatus capable of efficiently removing oil scum (solid oil + liquid oil) such as floating oil.

[0002]

2. Description of the Related Art The installation of grease straps in kitchen drains of restaurants and the like is obligatory by health centers. The grease straps are sharpened everywhere, but if you relax even a little and cleaning is not enough, the scums and other oils and fats that have been agglomerated will give off a bad smell and release the pollutants. Becomes

[0003]

Attempts to clean at this stage have conventionally been difficult and difficult. Some oil spill recovery machines were set up with a vacuum car, etc., but the scale was large. Furthermore, recently, there are places where a restaurant or the like is provided on the top floor of a high-rise building. In such a case, a hose is not connected, and cleaning is impossible. Also, in recent years, accidents such as ship distress and petroleum complexes may cause crude oil to spill and contaminate the shoreline with oil spills. When such a situation occurs, it is difficult to collect the floating oily matter at a complicated place such as a beach. Conventionally, it has been necessary to remove the oily oil with difficulty by scooping it with a dipper or the like.

An object of the present invention is to solve the above-mentioned problems, and an object of the present invention is to provide an oil spill recovery apparatus which can be reduced in size and portable, and can easily separate oil and water to remove oil spills.

[0005]

In order to achieve the above object,
The invention according to claim 1 includes a filler capable of adhering an oily substance, and a filter container having a space capable of accommodating the filler and having a permeable wall surface. Wherein the oil mixture is introduced into the filter container, and the filler is trapped in the oil container, while water is discharged to the outside of the filter container. Here, “oil suspension” refers to an oil component including a solid oil component and a liquid oil such as a floating oil. "Water" refers to an aqueous solution excluding liquid oil. According to a second aspect of the present invention, in the first aspect, the filter container is housed in a main body shell as a partition of a vertical vacuum cleaner, and a mixed oil solution is introduced into the filter container. A tube is provided, and a liquid discharge port is formed below the main body shell. A third aspect of the present invention is directed to the oily spill recovery apparatus according to the first or second aspect, wherein the lower surface of the filter container is formed of a metal perforated plate. According to a fourth aspect of the present invention, there is provided an oil spill recovery apparatus according to any one of the first to third aspects, wherein the filler is formed of an oil adsorbent.

According to the first aspect of the present invention, the oil mixture is poured into the filter container containing the filler, and the oil trap is captured by the filler. Since the packing captures only the oily spill to be obtained, the apparatus can be miniaturized. Further, since there is no water while collecting the same oily spill, the volume of the collected material itself can be reduced. According to the invention of claim 2, a short pipe for accommodating the filter container as a partition of the vertical vacuum cleaner and for guiding the oil suspension mixture into the filter container is provided, and a liquid discharge port is provided at a lower portion of the main body shell. When formed, the oil-slurry mixture can be sucked and processed using the suction pump of the vacuum cleaner, so that the start-up is rich and the operation is extremely easy. Further, when the lower surface of the filter container is formed of a metal perforated plate as in the invention of claim 3,
Since the separation of the oily spills and water from the filter proceeds quickly, the recovery operation is further accelerated. When the filler is composed of an oil adsorbent as in the invention of claim 4, the oil scum is more effectively removed by the adsorption action, so that the treatment of the oil scum mixture is further accelerated.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, an embodiment of an oil spill recovery apparatus according to the present invention will be described in detail. FIG. 1 to FIG. 3 show an embodiment of the oily spill recovery apparatus of the present invention, which is made small and portable. FIG. 1 is a longitudinal sectional view of the entire oily matter recovery apparatus, FIG. 2 is an exploded perspective view of FIG. 1, and FIG. 3 is a perspective view of a filter container and a filler.

[0008] The oil spill recovery device includes a cylindrical shell 1 having an open top, a cover 2 having a well-known suction pump capable of covering an open top, and a filter housed and set as a partition in the cylindrical shell. A container 3, a filler 4 stored in the filter container, a suction hose 5, a short pipe 6,
And a discharge hose 7.

A cylindrical shell 1 as a main body shell is a cylindrical body having a bottom, and is similar to an outer case portion of a so-called vertical vacuum cleaner.
A mounting nozzle 11 for the suction hose 5 is provided above the side wall 1a of the cylindrical shell, and a female screw portion is formed on the inner periphery of the base end of the mounting nozzle 11. Further, here, a discharge nozzle 12 serving as a liquid discharge port 12a is provided below the cylindrical shell. Then, a valve 13 is attached to the discharge nozzle 12.
This is so that the liquid discharge port 12a can be closed during the operation of collecting the oil suspension 91 (described later). Reference numeral 14 denotes a locking member for integrating the cover 2 covering the open port with the cylindrical shell 1, and reference numeral 15 denotes a caster for facilitating the movement of the oily matter collecting device.

The cover 2 has substantially the same structure as that of a general vertical cleaner, and includes a lid 21 for covering an opening and a head 23 for covering a known motor-driven suction pump 22. A bottomed cylindrical filter 24 is fixed to the lower surface of the lid 21, and the air 8 sucked together with the oily substance 91 is sucked up through the filter 24 by the suction pump 22, and In this configuration, the air is exhausted from the gap 25 of the portion 23 to the outside of the oil spill collection device. As the filter 24, for example, a sheet made of a nonwoven fabric or the like or a foamed plastic sheet having open cells is used as a tubular body, and a sealing plate 241 is attached to the lower surface thereof. Reference numeral 26 denotes a switch for activating the suction pump 22, reference numeral 27 denotes a cord, reference numeral 28 denotes an outlet (for a 100 V power supply), and reference numeral 29 denotes a handle that facilitates carrying the oily matter collecting device.

The filter container 3 is obtained by processing a container having an open top which is housed in the cylindrical shell 1 as a partition of a general-purpose vertical vacuum cleaner. The filter container 3
Is a cloth-like cylindrical portion 3 having a ring-shaped rubber seal ring 31 fitted to the opening edge of the cylindrical shell 1 with its outer diameter slightly reduced.
2 and a large number of through holes 33
1 is formed by sewn a metal perforated plate 33 on which is formed (FIG. 3). Since the tubular portion 32 is made of cloth, the tubular portion 32 also has a fine-grained through hole 321. However, the passage of the water 92 is poor and insufficient with the through hole 321 alone. The through-holes 331 of the perforated plate 33 help to facilitate the separation of the oily substance 91 and the water 92. The size of the through hole 331 is set according to the application, and the diameter of the through hole is preferably 1 mm to 20 mm (more preferably 2 mm to 5 m).
mφ). If the diameter of the through-hole is too small, it takes too much time to filter with the filter container 3. On the other hand, if the diameter of the through-hole becomes too large, a part of the sucked oil spill 91 flows down through the through-hole 331. It is because. Needless to say, it is not necessary to completely prevent the passage of the oily turbidity through the through-holes 331, and it is sufficient if the oily circulant is sucked into the filler 4 by circulating suction, but the working efficiency is deteriorated. A circular hole 34 is provided in the upper part of the cylindrical portion 32. When the filter container 3 is stored in the cylindrical shell 1, the circular hole 34 can face the hole of the mounting nozzle 11.

The filler 4 is a solid to which the oily substance 91 can adhere, and in this embodiment, a chip-like body made of an oil adsorbent is employed. The oil adsorbent has a lipophilic property and a water repellent property, and is a polymer compound such as polyethylene and polypropylene which is linearly connected on the basis of a CC bond. For example,
Toray Fine Chemical Co., Ltd.'s Toray Wosep (registered trademark), Mitsui Petrochemical Industry Co., Ltd.'s Tuffnel oil blotter (registered trademark), and the like. These are non-woven fabrics made of polypropylene and exhibit excellent oil absorption. The oil adsorbent may have a lipophilic property by making the fibers extremely thin or changing the cross-sectional shape in view of the physical structure. The shape of the filler 4 may be a ribbon or a tube, instead of the chip as in FIGS. Further, a sheet type or a mat type may be used, and these may be spread in the filter container 3. It is sufficient for the filler 4 to be capable of adhering oily spills, and it is possible to use the filler even if the performance is somewhat lower than that of the oil adsorbent. Can be adopted.

The short tube 6 is a tube whose outer periphery is threaded at the base end and whose end is an elbow-shaped tube. The short tube 6 penetrates the circular hole 34 after the filter container 3 is stored in the cylindrical shell 1,
The female nozzle of the mounting nozzle 11 is screwed from the inside of the filter container. Then, it is set so that the short tube tip is directed downward (FIG. 1). Here, the mounting nozzle 11 and the short pipe 6
Although a screwing method is adopted for the connection with the above, it is more preferable to adopt a locking structure that allows one-touch insertion. The suction hose 5 is a hose for sucking the oil mixture 9 from the suction port 52 into the oil collection device. Attach the base end 51 to the mounting nozzle 1
After being inserted into 1, it is screwed and fixed by the stopper 111. Further, the discharge hose 7 is attached to the discharge nozzle 12 and communicates with the bottom of the cylindrical shell, and recovers water 92 from the oil turbid mixture 9 sucked into the oil scum collection device (a drainage point such as a grease trap). Hose to return to.

An assembling procedure using the above components to form an oil spill recovery apparatus will be described below. First, the filter container 3 is set in the cylindrical shell 1. Then, the short hole 6 is fixed to the mounting nozzle 11 from the inside of the filter container 3 by aligning the circular hole 34 with the mounting nozzle position. Subsequently, the filler 4 is put into the filter container and packed in a predetermined amount. The type, amount, and porosity of the filler 4 clogged in the filter container 3 are determined by the oil mixture 9
Is selected as appropriate according to the situation. After a while, cover 2
Is put on the cylindrical shell 1, and the cover 2 and the cylindrical shell 1 are integrated with the locking member 14. Then, the suction hose 5 is inserted into the mounting nozzle 11 and tightened with the stopper 111,
Also, by attaching the discharge hose 7 to the discharge nozzle 12 as needed, the assembly of the oil spill recovery device is completed. With this completion, the inside of the oil spill collection device is
Three spaces S by the filter container 3 and the filter 24
₁ , S ₂ , S ₃ .

Next, the handling operation of the oil spill recovery apparatus assembled as described above will be described. First, oil spill 9
Place where you want to collect 1 (eg grease strap)
Transport the oil spill recovery unit to Then, the valve 13 is closed, and the outlet 28 is plugged into a power source. In such a standby state, the suction hose 5 is held in hand, the switch 26 is turned on, and the suction pump 22 is operated. After a while, suction hose 5
Into the oil mixture 9.

Then, the oil suspension mixed liquid 9 sucked from the suction port 52 is carried into the filter container 3 through the suction hose 5 and the short pipe 6. Since the valve 13 is closed, the liquid discharge port 12a is closed, and the suction force of the oil spill recovery device is maintained. In some cases, air 8 is entrained from the suction port 52 together with the oil mixture 9, and the air 8 is supplied to the filter 24.
And separated from the oil mixture 9 and exhausted through the gap 25 to the outside of the system. On the other hand, in the oil mixture 9 sucked into the filter container 3, the oil 91 therein is adsorbed and captured by the filler 4. And the remaining water 92
It passes through the filler 4 and is separated by the cylindrical portion 32 and the perforated plate 33, passes through the through holes 321 and 331, and accumulates in the space S ₁ at the bottom of the cylindrical shell 1. In this way, the water 92 is accumulated in the space S _1, when it reaches a predetermined amount, push up the float (not shown), the suction pump 22 is automatically stopped. In such a state, the valve 13 is opened, and the water 9 collected at the bottom of the cylindrical shell 9 is opened.
2 is returned through a discharge hose 7 to a grease strap or the like serving as a drain port.

After that, the valve 13 is closed again, the oil mixture 9 is taken into the filter container 3, and the above operation is repeated. The switch 26 is turned off when the oily substance 91 is sufficiently adsorbed and captured on the packing 4. Then, the locking member 14 is removed, and the cover 2 is removed from the cylindrical shell 1. Next, the filter container 3 housed in the cylindrical shell 1 is lifted, and the filler 4 on which the oily substance 91 is adhered is taken out from the inside and collected and disposed. If necessary, a new filler 4 is charged into the filter container 3, an oil spill recovery device is assembled, and the above-described oil spill recovery operation is repeated.
The cleaning and removal of 1 (scums) are completed.

The oil spill recovery apparatus thus constructed sucks the oil spills 91 from the suction port 52 in the manner of a vacuum cleaner and causes the filler 4 to catch the oil spills 91. Is extremely easy. The filter 24 and the filter container 3 define three spaces S ₁ , S
Since it is partitioned into S ₂ and S ₃ , the air 8 -water 92 -oil 91 can be separated well. In particular, the through holes 3 of the perforated plate 33
31 improves drainage and promotes the flow of water 92. And
Oil scum and floating oil contaminants in a narrow place can be easily sucked up, so that it can exert its power even if it is stained with grease traps or beaches such as beaches. Further, the oily oil recovery apparatus of the present invention efficiently causes only the oily oil 91 in which oils and fats are aggregated from the oily oil mixture 9 to be efficiently captured by the filler 4, Is fed back, so the amount of disposal that must be disposed of by cleaning is much smaller than in the conventional method. For example, in an oil spill recovery machine using a vacuum car or the like, the water 92 is sucked up and collected together with the oil spill, so that even if the oil spill is not removed so much, the collection capacity becomes full immediately. There was a problem. In addition, it transports water 92 that is not originally necessary,
And because it was disposed, efficiency was poor. In the oil spill recovery device of the present invention, only the oil spill that must be collected is collected, so that even a small-sized oil spill recovery device has a large cleaning and removing ability. . In addition, if the filler 4 that has collected and adhered the oily substances 91 is an oil adsorbent mainly composed of polypropylene or the like, the oil adsorbing power is excellent, and these are harmless. it can. Also, at this time, since the water 92 is removed as described above, the fuel efficiency is not increased, and the efficiency is improved. In addition, the oil spill recovery apparatus of the present invention,
Since it is possible to reduce the size and make it a general-purpose type, the required space is small, and since it can be carried and stored anywhere, it can be turned around in an emergency and can quickly respond to oil spill collection. Even when cleaning the grease strap at the restaurant on the top floor of the building, it can be easily carried using an elevator or the like to collect oil spills.

It should be noted that the present invention is not limited to the embodiment described above, but can be variously modified within the scope of the present invention depending on the purpose and application. The shape, size, material and the like of the cylindrical shell 1, the cover 2, the filter container 3, the filling material 4, the short tube 6, etc. are appropriately selected according to the application. For example, filter container 3
As for the wall surface, not only the bottom plate perforated plate 33 but also the side wall tubular portion can be formed by a perforated plate such as a punching plate.

[0020]

As described above, the oil spill recovery apparatus of the present invention can be made compact and portable, can easily remove oil spills, and uses an oil adsorbent as a filler. In such a case, a great effect is exhibited, for example, the ability to capture oily scum is high, and incineration can be performed as it is.
