Abstract: Provided is a toothed drum type oil recovery device, which includes: a recovery drum having a center coupled to a rotary shaft and having a plurality of tooth units formed around an outer circumference thereof, wherein one side of the recovery drum is disposed in the water to which oil is spilled so that the oil is recovered by the tooth unit at one side of the recovery drum according to the rotation; and a separation unit containing an oil separating liquid and disposed at the other side of the recovery drum, wherein when the tooth unit moves onto the oil separating liquid at the other side of the recovery drum according to the rotation of the recovery drum, the oil separating liquid is introduced into a space between the tooth units adjacent to each other by means of a capillary action to separate the oil from the tooth unit.

Abstract: The present disclosure is directed to providing a toothed conveyor belt type oil recovery device including: a recovery conveyor which is rotates in such a way that a continuous track rotates, the recovery conveyor having multiple teeth made of a hydrophilic material on an outer surface, the recovery conveyor having one side positioned in water in which oil is spilled to recover the oil while feeding the oil into a space between the adjacent teeth by the rotation; and a separation unit which holds an oil separating liquid, and is positioned on the other side of the recovery conveyor to separate the oil from the teeth while the oil separating liquid is fed into the space between the adjacent teeth by capillary suction when the teeth move on to the oil separating liquid on the other side of the recovery conveyor by the rotation of the recovery conveyor.

Abstract: The present disclosure is directed to providing an oil-water separation filter structure including a base guide having a separated water outlet hole through which a fluid separated from a mixed fluid including an impurity exits, an oil-water separation filter disposed on the base guide to separate the impurity and the fluid included in the mixed liquid, and a top guide disposed on the oil-water separation filter, having at least one mixed fluid inlet hole through which the mixed fluid enters, and coupled to the base guide.
According to the present disclosure, the oil-water separation filter structure includes a hydrophilic material to separate water and oil, and as opposed to the existing nonwoven fabric type filters, can be continuously used, thereby preventing environmental pollution problems.
