[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an oily substance collecting apparatus that can efficiently remove oily substances (solid oil + liquid oil) such as floating oil.
[0002]
[Prior art]
The public health center is obligated to install a grease trap for kitchen drainage in restaurants and other places. Care is taken everywhere to clean the grease trap, but if you feel a little nervous and do not clean enough, the oily substance, such as scum, that has agglomerated fat and oils gives off a foul odor and pollutes It becomes.
[0003]
[Problems to be solved by the invention]
Attempting to clean up at this stage has traditionally been difficult and difficult. There are some oil turbidity recovery machines that are set in a vacuum car, etc., but it was a big deal. Furthermore, recently, there are places such as a restaurant on the top floor of a high-rise building. In such a case, the hose is not connected and cleaning is impossible.
Also, in recent years, there are cases where crude oil spills and the coastline is polluted by oil spills due to accidents such as shipwrecks and oil complexes. When such a situation occurs, it is difficult to recover the floating oil in the place where the soot and the like are intricate. Conventionally, it has been necessary to remove it with difficulty by scrubbing with ladle.
[0004]
SUMMARY OF THE INVENTION An object of the present invention is to solve the above-described problems, and to provide an oil turbid recovery device that can be reduced in size and carried and can be easily separated into oil and water to remove oil turbidity.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, according to the first aspect of the present invention, there is provided a body shell as a partition of a vertical vacuum cleaner, a main body shell having a filler capable of adhering oil and a space for accommodating the filler, and having a wall surface. An oily substance characterized in that a water-permeable filter container is housed, a short pipe for introducing an oily substance mixture into the filter container is provided, and a liquid discharge port is formed at the lower part of the main body shell . In the recovery unit.
Here, the “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.
The invention of claim 2 is characterized in that the lower surface of the filter container is formed of a metal perforated plate .
The invention of the oil spill recovery device according to claim 3 is characterized in that, in claim 1 or 2, the filler is composed of an oil adsorbing material .
[0006]
As in the first aspect of the invention, the oil mixture is put into the filter container containing the filler, and the oil is captured by the filler. On the other hand, when water is discharged outside the filter container, the oil is tried to be recovered. Since the filler captures only the oil turbidity, the equipment is downsized, and while collecting the same oil turbidity, there is no water, so the volume of the recovered material itself can be reduced , and as a partition for a vertical vacuum cleaner wherein the short pipe leading to pollution liquid mixture into the filter vessel with a filter container for housing provided, the the body at the bottom of the shell to form a liquid outlet, with the suction pump of the cleaner pollution liquid mixture Can be sucked in, so it has excellent startability and makes workability extremely easy.
Further, when the lower surface of the filter container is formed of a metal porous plate as in the second aspect of the invention, the oil separation and water are separated quickly, so that the recovery operation is further increased.
As in the third aspect of the invention, when the filler is composed of an oil adsorbing material, the oil turbidity is more effectively removed by the adsorption action, so that the treatment of the oil turbid mixture further increases.
[0007]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of an oily substance collection device according to the present invention will be described in detail.
FIGS. 1 to 3 are one embodiment of the oil turbidity recovery apparatus of the present invention, and are made into a small and portable type. FIG. 1 is a longitudinal sectional view of the whole oil spill collecting device, 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 turbidity recovery apparatus includes a cylindrical shell 1 with an open top surface, a cover 2 that includes a known suction pump and can cover the open top surface, and a filter container 3 that is stored and set as a partition in the cylindrical shell. , A filler 4 accommodated in the filter container, a suction hose 5, a short pipe 6, and a discharge hose 7.
[0009]
The cylindrical shell 1 which is a main body shell is a bottomed cylindrical body, which 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 on the upper portion of the side wall 1a of the cylindrical shell, and a female screw portion is formed on the inner periphery of the base end portion of the mounting nozzle 11. Further, here, a discharge nozzle 12 serving as a liquid discharge port 12a is provided at the bottom of the cylindrical shell. A valve 13 is attached to the discharge nozzle 12. This is because the liquid discharge port 12a can be closed during the operation of collecting the oil turbidity 91 (described later).
Reference numeral 14 denotes a locking tool that integrates the cover 2 with the opening closed into the cylindrical shell 1, and reference numeral 15 denotes a caster that makes it easy to move the oil collection device.
[0010]
The cover 2 is substantially the same as the cover structure of a general vertical vacuum cleaner, and includes a lid portion 21 that covers an open port and a head portion 23 that covers a known motor-driven suction pump 22. A bottomed cylindrical filter 24 is fixed to the lower surface of the lid portion 21, and the air 8 sucked together with the oil turbidity 91 is sucked up through the filter 24 by the suction pump 22, In this configuration, the air is exhausted from the gap 25 of the section 23 to the outside of the oil collecting device. As the filter 24, for example, a sheet-like body made of a nonwoven fabric or the like, a foamed plastic sheet having a continuous foam property or the like is formed into a cylindrical body, and a sealing plate 241 is attached to the lower surface thereof.
Reference numeral 26 is a switch for operating the suction pump 22, reference numeral 27 is a code, reference numeral 28 is an outlet (for 100V power supply), and reference numeral 29 is a handle for making it easy to carry the oil collecting device.
[0011]
Here, the filter container 3 is obtained by processing a container with an open top surface that is housed in the cylindrical shell 1 as a partition for a general-purpose vertical vacuum cleaner. The filter container 3 is attached to a ring-shaped rubber seal ring 31 aligned with the opening edge of the cylindrical shell 1 by attaching a cloth cylinder portion 32 with a slightly smaller outer diameter than this, and further, a large number of them are attached to the lower surface of the cylinder portion 32. The metal perforated plate 33 in which the through holes 331 are formed is sewn (FIG. 3). Since the cylindrical portion 32 is made of cloth, the cylindrical portion 32 also has fine through holes 321.
However, the passage of the water 92 is bad and not sufficient with the through-hole 321 alone. The through holes 331 of the perforated plate 33 are useful for smoothly separating the oily turbid material 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 in the range of 1 mmφ to 20 mmφ (more preferably 2 mmφ to 5 mmφ). If the through-hole diameter is too small, it takes too much time to filter through the filter container 3. On the other hand, if the through-hole diameter is too large, a part of the sucked bent oil 91 flows down through the through-hole 331. Because it ends up. Of course, it is not necessary to completely block the passage of the oil turbidity at the through-hole 331, and it is sufficient to circulate and suck the oil turbidity in the filler 4, but the working efficiency is deteriorated.
A circular hole 34 is provided in the upper part of the cylindrical portion 32, and when the filter container 3 is stored in the cylindrical shell 1, the circular hole 34 can be opposed to the hole of the mounting nozzle 11.
[0012]
The filling 4 is a solid to which the oily turbid material 91 can adhere, and in this embodiment, a chip-like body made of an oil adsorbent is employed.
The oil adsorbent is a lipophilic and water-repellent polymer compound such as polyethylene or polypropylene that is connected in a straight chain with a C—C bond base. For example, there are Toray Wosepp (registered trademark) manufactured by Toray Fine Chemical Co., Ltd., and Tafnel Oil Blotter (registered trademark) manufactured by Mitsui Petrochemical Industries, Ltd. These are non-woven fabrics made from polypropylene and have excellent power for oil adsorption.
The oil adsorbing material may have a lipophilic property by making the fibers extremely fine from the physical structure surface or changing the cross-sectional shape.
The shape of the filling 4 may not be a chip-like body as shown in FIGS. Further, it may be of a sheet type or a mat type, and these can be spread in the filter container 3.
It is sufficient for the filler 4 to be able to adhere an oil turbidity, and it can be used for the filler even if its capacity is somewhat lower than that of the oil adsorbent. For example, a material such as oil-absorbing paper, wood chips, sponge, net, etc. Can be adopted.
[0013]
The short tube 6 is a tube body that is threaded on the outer periphery of the proximal end portion and has an elbow-shaped distal end portion. The short tube 6 is inserted into the female screw portion of the mounting nozzle 11 from the inside of the filter container through the circular hole 34 after the filter container 3 is stored in the cylindrical shell 1. And it sets so that a short tube front-end | tip part may face down (FIG. 1). Here, a screwing method is employed for the connection between the mounting nozzle 11 and the short tube 6, but 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. After the base end portion 51 is inserted into the mounting nozzle 11, the base end portion 51 is screwed and fixed by the stopper 111. Further, the discharge hose 7 is attached to the discharge nozzle 12 and communicated with the bottom of the cylindrical shell, and the water 92 is taken from the oil mixture 9 sucked into the oil collection device (drainage place such as grease trap). It is a hose to return to.
[0014]
Next, an assembly procedure to make an oil turbidity recovery apparatus using the above components will be described.
First, the filter container 3 is set in the cylindrical shell 1. Then, the circular hole 34 is aligned with the mounting nozzle position, and the short tube 6 is fixed to the mounting nozzle 11 from within the filter container 3. Subsequently, the filler 4 is put into the filter container and packed in a predetermined amount. The type, amount and porosity of the packing 4 packed in the filter container 3 are appropriately selected according to the situation of the oil mixture 9.
Thereafter, the cover 2 is put on the cylindrical shell 1, and the cover 2 and the cylindrical shell 1 are integrated by the locking tool 14.
Then, the suction hose 5 is inserted into the attachment nozzle 11 and tightened with the stopper 111, and the discharge hose 7 is attached to the discharge nozzle 12 as necessary, thereby completing the assembly of the oil collection device. With this completion, the inside of the oil spillage recovery device is divided into three spaces S ₁ , S ₂ , S ₃ by the cylindrical shell 1, the filter container 3, and the filter 24.
[0015]
Next, the handling operation of the oil turbidity recovery apparatus assembled as described above will be described.
First, the oil spill recovery device is transported to a place (for example, a grease trap) where the oil spill 91 is to be recovered. Then, the valve 13 is closed and the outlet 28 is plugged into the power source. In such a standby state, the suction hose 5 is held in the hand, the switch 26 is turned on, and the suction pump 22 is operated. Thereafter, the suction port 52 of the suction hose 5 is pushed into the oil mixture 9.
[0016]
Then, the oil mixture 9 sucked from the suction port 52 passes through the suction hose 5 and the short pipe 6 and is carried into the filter container 3. Since the valve 13 is closed, the liquid discharge port 12a is closed, and the suction force of the oily substance collection device is maintained.
There is a case where air 8 is accompanied together with the oil mixture 9 from the suction port 52, but the air 8 is separated from the oil mixture 9 by the filter 24 and passes through the gap 25 from the outside of the system. Is exhausted. 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. The remaining water 92 passes through the filler 4, is separated by the cylindrical portion 32 and the porous 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, when water 92 accumulates in the space S ₁ and reaches a predetermined amount, the float (not shown) is pushed up, and the suction pump 22 is automatically stopped.
In such a state, the valve 13 is opened, and the water 92 accumulated at the bottom of the cylindrical shell is returned through the discharge hose 7 to a grease trap or the like serving as a drain outlet.
[0017]
Thereafter, the valve 13 is closed again, the oil mixture 9 is taken into the filter container 3, and the above-described operation is repeated.
When the oily substance 91 is sufficiently adsorbed and trapped in the filling 4, the switch 26 is turned off. Then, the locking tool 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 with the oil turbidity 91 adhered is taken out from the inside and collected for disposal.
If necessary, a new filler 4 is put into the filter container 3 to assemble an oil turbid recovery device, and the above oil turbid recovery operation is repeated. )) To complete the cleaning removal.
[0018]
Unlike the conventional difficult manual operation, the operation of the oil turbidity recovery device configured in this way is very easy because the oil is sucked from the suction port 52 in the manner of a vacuum cleaner and the filling material 4 captures the oil turbidity 91. Become. Oil pollution substance collecting device inside the filter 24, so is partitioned into three spaces S _1, S _2, S ₃ by the filter container 3, the air 8 water 92- pollution 91 is successfully separated. In particular, the through holes 331 of the perforated plate 33 improve drainage and promote the flow of the water 92. And since it is possible to easily suck up oil turbids and floating oil contaminants in a narrow place, it can be effective even for grease trap dirt or coastal contamination such as dredging.
Furthermore, the oil turbidity recovery apparatus of the present invention efficiently captures only the oil turbidity 91 in which the fats and oils and the like are aggregated from the oil turbid mixture 9 and the water 92 in the oil turbid mixture 9. Therefore, the amount of collected waste that must be disposed of by cleaning is much smaller than that of the conventional method. For example, an oil collection machine using a vacuum car, etc., sucks up and collects water 92 together with the oil turbidity, so even if the oil turbidity has not been removed so much, the collection capacity can be quickly filled. There was a bug. Moreover, since the water 92 which was originally not necessary was transported and disposed of together, the efficiency was poor. In the oil turbidity recovery device of the present invention, only the oil spillage that must be recovered is recovered, so even with a small type oil turbidity recovery device, the cleaning and removal capability is large. .
In addition, if the filler 4 on which the oil turbidity 91 is collected and adhered is an oil adsorbent mainly composed of polypropylene or the like, the oil adsorbing power is outstanding, and since these are harmless, they are incinerated as burnable garbage. it can. At this time, as described above, the water 92 is removed, so that the fuel efficiency is not increased and the water 92 is more effective.
In addition, since the oil spillage recovery apparatus of the present invention can be reduced in size and can be made into a general type, the required space is small, and it can be carried and stored anywhere. It can respond quickly to oil spill recovery. Even when cleaning grease traps at restaurants, etc. on the top floor of the building, they can be easily carried using an elevator or the like to collect oily matter.
[0019]
In addition, in this invention, it is not restricted to what is shown to the said embodiment, According to the objective and a use, it can change variously in the range of this invention. The shape, size, material, etc. of the cylindrical shell 1, the cover 2, the filter container 3, the filler 4, the short tube 6, etc. are appropriately selected according to the application. For example, the wall surface of the filter container 3 can be formed not only by the porous plate 33 of the bottom plate but also by a porous plate such as a punching plate in the side wall cylinder portion.
[0020]
【The invention's effect】
As described above, the oil turbidity recovery apparatus of the present invention can be reduced in size and carried, can easily remove the oil turbidity, and if an oil adsorbent is used as the filler, It has a great effect such that it has a high ability to capture objects and can be incinerated as it is.
