Description

Oil Skimmer {OIL-SKIMMER}

The present invention relates to an oil skimmer which collects floating matters such as oil floating in rivers, lakes and oceans due to floating matters or oil accidents floating on the surface of water purification plants. It relates to an oil skimmer which is picked up by suction and collected.

Generally, a large amount of floats or scums are suspended in water purification in a water purification plant or sewage treatment plant. When an oil accident occurs in a river, lake, ocean, etc., oil floats on the water. Of course, there is a problem of destroying the ecosystem.

Thus, there are many known and used devices for collecting float floating on the water surface. Therefore, commonly known suspended matter collecting device is a belt skimmer or a 'siphon scum remover' of Korean Utility Model Registration No. 2002-1325, and a scum removal device of an injury separation tank of Korean Utility Model Registration No. 2001-22967. Known.

Particularly, the floating inhaler, which is filed in Korean Patent No. 10-2007-0124818, has excellent performance and excellent collection efficiency, but the inflow control floater mounted in the inhaler can move freely according to the water level in the inhaler to control the inflow rate well. If the water is sewage, foreign matter may be caught between the inlet control floater and the inhaler outer body, and if the viscosity of the oil floating on the water is high, the oil may be caught in the gap, interfering with the activity of the inlet control floater. There is a problem that the function of the inhaler is lost, and when the gap between the inlet control floater and the external body is increased, a lot of water is introduced to increase the load of the aftertreatment process and decrease the performance.

The present invention has been invented to solve the above problems, and even in harsh environmental conditions, it is possible to collect oil or foam that floats on the surface of reservoirs, lakes, rivers, seas, etc. To provide an oil skimmer with excellent performance.

The present invention for achieving the above object, includes a floating means to float on the water surface, the inlet is provided in the upper and rear of the receiving space is provided with the top is open and blocked in all directions, the lower side of the receiving space The main body is provided with an outlet for sending the fluid to the outside; Each of the front and rear inlets is connected to the body without any gap with a flexible material such as a rubber plate that can be tilted well, and the other side is provided with a floating cylinder to float on the surface of the receiving space, When the suction force is generated, the inclination is adjusted to the floating cylinder which is lowered along the water level of the lower receiving space.The inflow channel opens to open the inlet channel and generates a drop down to introduce the floating water and water from the outer surface into the receiving space and reach the outlet. It relates to an oil skimmer comprising.

The present invention has a simple structure of easily inhaling external water and suspended solids because it is equipped with the automatically regulated inflow regulator, the inflow adjustment is made easily from the outside, smooth operation even in sewage, or oil of high viscosity performance under adverse conditions There is an advantage that can be used well.

3 and 4, when the oil skimmer is stopped, the main body 10 is submerged in the water including the inlet 50 by the buoyancy means 30, and only a part of the inlet 50 and the main body 10 is stopped. Since the water floats on the water and a predetermined gap is formed between the left and right surfaces of the inflow regulator 20 and the main body 10, the water introduced from the outside of the main body 10 through the gap receives the accommodation space 11. ) Fresh water inside. Accordingly, when the suction means (not shown) is not operated, the water surface 60 on the outside of the main body 10 and the water surface inside the accommodation space 11 are positioned on the same horizontal line, so that the inflow regulator 20 and the float 21 are also located on the same horizontal line. As a result, the receiving space 11 floats on the water surface 61.

3 and 5, when the suction means (not shown) is operated, the suction force is generated through the outlet 12 of the main body 10. Accordingly, the surface 61 of the receiving space 11 is lowered by the suction force through the outlet 12, and the floating cylinder 21 of the inflow regulator 20 descends along the water surface 61, and the upper portion of the inflow regulator 20 is Positioned below the outer surface 60 of the main body 10, a drop is generated between the outer surface 60 of the main body 10 and the receiving surface 11 of the receiving space 11, and water and floats outside the main body 10. Is to flow into the inflow regulator 20 to enter into the receiving space (11).

The water and the suspended matter introduced into the receiving space 11 is passed through the outlet pipe 40 to the suction means (not shown) through the outlet port 12.

Referring to FIG. 5, when the floating layer is thick on the water surface 60 outside the main body 10, the suction force of the suction means (not shown) is strongly generated to increase the passage amount of the outlet 12. The water level 61 is further lowered down and the inflow regulator 20 is further lowered to increase the fall, and a large amount of water and float flows to the upper portion of the inflow regulator 20 to enter into the receiving space (11).
