The present invention relates to a floating oil removing device for removing suspended oil from waste oil pits, and more particularly, to a floating oil removing device for removing floating oil suspended above waste oil by rotating cooking.

In general, the rolling line of the steel mill removes heat generated during rolling and uses rolling oil to protect the surface of the product.

The waste oil generated by the use of the rolled oil is collected in the waste oil pit, and the waste oil collected in the waste oil pit is sulfuric acid is added thereto so that the oily solution is destroyed.

Waste oil from which the oily liquid is destroyed is separated by the air blowing, and the oil component is floated to the upper part of the water, and the injured oil is collected by the oil storage tank and incinerated at the incinerator, and the lower part is transferred to the wastewater treatment process. Water treatment.

Therefore, the waste oil treatment facility for treating such waste oil is waste oil generated in the rolling process as shown in Figure 1 to the first step 111, which is a post-process along the transfer pipe 110 by the pumping of the storage tank. Sulfuric acid is introduced into the waste oil received in the first and second feet 111.

In addition, the waste oil is destroyed by the sulfuric acid introduced, and the broken oil is separated into the floating oil at the top and the water at the bottom of the floating oil.

In addition, when the waste oil is separated and floated, air blowing is performed to promote separation of oil components, and the suspended oil is inclined by the rubber plate 115 attached to the plot 114 of the oil skimmer 113. Oil passed over 103 to the secondary pit 101, and the oil carried to the secondary pit 101 is collected into the oil reservoir 106.

The suspended oil transferred to the oil storage tank 106 is incinerated by the oil pump 104 and is incinerated, and the water below the suspended oil flows to the secondary pit 101 by the transfer pump 109 so that residual oil and water Finally separated and transferred to the wastewater treatment process by the wastewater pump 105 is processed.

However, such a conventional waste oil treatment facility takes a long time for the waste oil treatment operation, and the rubber plate attached to the oil skimmer passes through the hopper table, and when the collision with the hopper table occurs, most of the oil collected by the vibration is scattered backward.
