Therefore, when the pump body 24 is operated to suck and discharge fluid through the through hole 23d, as shown in FIG. 5, the check valve 23b is repeatedly opened and closed in opposition to the suction pipe 21. Water and oil are sucked through the tip of the feeder and supplied to the storage chamber 11.

In addition, the suction induction body 30 is composed of a cylindrical body 31 having an upper end and an elongated cylindrical shape and an upper end portion thereof, and a buoyancy body 32 fixed to the opening 31a of the cylinder body 31. And, it is installed to be locked in the interior of the collecting container (1).

At this time, the main body 31 is formed of a bellows shape is formed in a plurality of wrinkles on the circumferential surface and stretch in the vertical direction and is installed so as to be immersed in water and oil contained in the collection container 1, the water and oil opening It is configured to flow into the inside of the main body 31 through the (31a).

In addition, the maximum expansion length of the cylinder body 31 is formed so that the height of the collection container 1 corresponds to, the opening of the cylinder body 31 only the oil stored in the collection container (1) if possible Note the ingress through 31a).

In addition, the buoyancy body 32 is fixed to the inside of the main body 31 so as to be close to the opening 31a of the main body 31, the water and oil flows into the inside of the main body 31 to the buoyancy It rises to the upper side so that the tube body 31 is extended upward. At this time, the suction pipe 21 is fixed so that the front end portion is fixed to the inside of the main body 31 so as to suck the water and oil introduced into the inside of the main body 31.

And, in another embodiment, the oil-water separator according to the present invention, as shown in Figure 6, the installation plate to easily suck the water and oil in the interior of the above-mentioned collection container 1 to provide to the body 10 A suction member 40 consisting of a 41 and a waterproof and suction / dischargeable submersible motor 43 may be further provided.

The installation plate 41 is formed in a plate shape for the installation of the submersible motor 43 and the suction induction body 30, the moving tube 42 is formed on the inner side is fixed to the inner bottom surface of the collecting container (1). . The submersible motor 43 has a lower portion fixed to one side of the upper surface of the installation plate 41 so as to suck the water and oil collected in the suction induction body 30 to the main body 10. The nozzle 44 is connected to the suction pipe () for transferring water and oil to the main body 10 is located inside the collection container (1).

At this time, the suction induction body 30 is fixedly installed on the other side of the submersible motor 43 installed on one side of the upper surface of the mounting plate 41 is connected to the moving tube 42 formed inside the mounting plate 41 Note that

That is, the water and oil collected inside the collecting container 1 are not mixed with each other due to the difference in specific gravity, and water having a high specific gravity is first stored in the lower part of the inside of the collecting container 1 and oil is stored thereon. If only oil is sucked through the opening 31a formed in the upper part of the cylinder body 31 of the induction cylinder 30 and stored inside, the moving tube 42 formed inside the mounting plate 41 by the suction operation of the underwater motor 43. Since the oil is moved through the nozzle 44 connected to the suction pipe 21 on the upper portion of the underwater motor 43 and moved to the main body 10 to separate the oil and water, oil and water can be separated more easily.

Therefore, the pump unit 20 may perform the role of the pump unit 20 through the submersible motor 43 without a separate pump unit 20.

At this time, the outer circumferential surface of the suction guide cylinder 30 installed on the mounting plate 41 to guide the suction guide cylinder 30 to prevent the phenomenon inclined in an irregular direction due to the wave of water and oil having a liquid property Note that the tube 45 may be further provided.

Referring to the operation of the oil-water separator configured in this way is as follows.

First, as shown in FIG. 7A, when the suction induction cylinder 30 is installed to be contained in the collection container 1 in which water and oil are stored, the water and oil are formed in the opening of the cylinder body 31. 31a) is introduced into the main body 31 to float the buoyancy body 32, accordingly, as shown in Figure 6 (b), the main body 31 is extended to the main body 31 The top of the float rises to the surface of the water and oil, when a sufficient amount of water and oil flows into the inside of the main body 31, the top of the main body 31 to the upper surface of the water and oil contained in the collection container (1) It floats up so that no more water and oil flow into the interior of the collecting container (1).

When the pump 22 is operated, water and oil contained in the suction induction body 30 are sucked through the suction pipe 21 and supplied to the storage chamber 11 to be primarily stored. When the water and the oil inside the main body 31 are discharged, the buoyancy body 32 and the opening 31a at the upper end of the main body 31 are lower than the water surface of the water and oil stored in the collection container 1. As a result, when the water and oil contained in the collection container 1 flows into the inside of the main body 31 again, the upper opening 31a of the main body 31 floats to the top of the water and oil. As such, the operation of elevating the upper end portion 31a of the tube body 31 is continuously repeated by the action of the pump 22. At this time, since the oil rises to the upper portion of the water by the difference in specific gravity, when the opening 31a of the tube body 31 is lowered, the oil which floats to the upper portion of the water preferentially flows into the inside of the tube body 31.

When water and oil flow into the storage chamber 11, the water and oil are separated again due to the specific gravity difference so that the oil floats on the upper surface of the water, and the lower water is separated through the connecting pipe 15b for the second separation. The oil introduced into the chamber 13 and the oil on the upper side flows into the first separation chamber 12 through the opening 15a formed in the diaphragm 14 and separated from each other, and then separately through the drain pipes 12a and 13a. Discharged.

The oil-water separator configured as described above uses the pump unit 20 to suck water and oil stored in the collecting container 1 and store the oil and water in the storage chamber 11, and the water and oil are separated from each other by specific gravity. Since water and oil are separated by entering the second separation chambers 12 and 13 to be discharged through separate drain pipes 12a and 13a, the structure is simple and the water and oil can be efficiently separated. .

In addition, the suction pipe 21 is provided with a suction induction cylinder 30 composed of a cylinder body 31 and a buoyancy body 32 at the distal end of the suction tube 21, according to the amount of water and oil introduced into the cylinder body 31. By repeating an action in which the opening 31a at the top of the cylinder body 31 rises to the surface of the water and oil stored in the collection container 1 or sinks to the lower side of the water surface, the oil which rises to the top of the water is preferentially the cylinder body 31. The oil is separated firstly by letting it flow into the inside of the tank. Therefore, not only the efficiency of separating oil and water is further increased, but the minimum amount of water is mixed when supplying the oil rising to the upper portion of the water to the storage chamber 11, thus the amount of water and oil supplied to the storage chamber 11. Since it can be reduced, there is an advantage that can minimize the size of the pump 22 and the main body 10.

That is, since the amount of oil stored in the collecting container 1 is very small compared to the amount of water, when the oil mixed with water is simply supplied to the storage chamber 11 using the pump unit 20, a large amount of water Since the oil and the oil to be supplied to the storage chamber 11 together, the capacity of the pump 22 and the size of the storage chamber 11 of the main body 10 should be increased, the oil-water separator according to the present invention is the suction induction cylinder ( Since it is configured to preferentially suck the oil using 30, the amount of water supplied to the storage chamber 11 is minimized, thereby minimizing the size of the pump 22 and the main body 10.

In addition, the pump 22 is composed of a valve body 23 having a check valve 23b therein, and a pump body 24 connected to the valve body 23, so that the piston of the pump body 24 is provided. As 24a moves forward and backward, it is configured to alternate between suction and discharge of water and oil. Therefore, since the suction induction cylinder 30 repeatedly expands and contracts by intermittently inhaling the water and the oil in the suction induction cylinder 30, the oil that floats to the upper portion of the water in the collection container 1 is effectively the suction induction cylinder 30. ) Has an advantage that can be effectively introduced into the interior.

The specific embodiments of the present invention have been described above.

However, the spirit and scope of the present invention is not particularly limited to these specific embodiments, and it is common knowledge in the art that various modifications and variations can be made without departing from the spirit of the present invention. Those who have a must understand.
