CROSS REFERENCE TO RELATED APPLICATION

The present disclosure claims the benefit of Korean Patent Application No. 10-2019-0116864 filed in the Korean Intellectual Property Office on Sep. 23, 2019, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present inventive concept relates to an oil-water separator for oil-containing residues, and more particularly, to an oil-water separator for oil-containing residues that is capable of performing first filtering for the residues to separate the residues having large particles and then performing second filtering for contaminated water separated from the filtered residues to separate and discharge oil and water contained in the contaminated water, independently of each other.

BACKGROUND

A large amount of waste oil is generated in a kitchen in which a large amount of oil is used to make fried food.

During containers with oil stains are washed, especially, waste water in which oil and sludge are admixed is generated. If high temperature water is used to perfectly remove the oil stains from the containers, at this time, steam is also generated.

If the waste water mixed with oil is drained to a sewage pipe, without any treatment, a complicated and high cost treatment system and a long period of treatment time are needed to dissolve the oil, and if the waste water mixed with oil flows to lakes and rivers in a state where the oil is not dissolved perfectly, serious environmental problems may occur due to eutrophication of lakes and rivers. Further, the drain may be often clogged.

Accordingly, various treatments and devices such as an oil-water separator into which a filter is introduced have been developed to perform oil dissolution or oil separation for waste water mixed with oil.

In case of the oil-water separator using the filter, however, the filter has to be frequently exchanged with new one, which requires continuous cares and high costs for the cares, and even if the filter is not used in the oil-water separator, it is hard to collect the separated oil. If the sludge containing the oil is not collected early, an expected oil separation effect cannot be obtained.

Since a device for collecting the sludge has to be separately placed, further, an installation area of the oil-water separator becomes bulky to cause problems on an installation space and a treatment cost, thereby avoiding a treatment for the waste water mixed with oil or failing to perform the treatment appropriately.

SUMMARY

Accordingly, the present inventive concept has been made in view of the above-mentioned problems occurring in the related art, and it is an object of the present inventive concept to provide an oil-water separator for oil-containing residues that is capable of being simple in structure to achieve compactualization and reduction in a manufacturing cost, minimizing problems on an installation space, and reducing a treatment cost required for oil-water separation.

To accomplish the above-mentioned object, according to the present inventive concept, there is provided an oil-water separator for oil-containing residues, including: an outer casing configured to allow residues containing oil and water to be put thereinto; a filter member for separating the oil and the water contained the residues from each other; and a filter support frame coupled to the filter member in such a manner as to be separably seated inside the outer casing, wherein the oil and the water are passed through the filter member at different speeds from each other.

According to the present inventive concept, desirably, the oil-water separator further includes: a filter hitting part for receiving an external force to hit the filter support frame; and a pedal part for rotating the filter hitting part.

According to the present inventive concept, desirably, the filter hitting part includes hitting means constituted of at least one or more hitting members having a shape of a cam having a given curvature in an outermost shape thereof in such a manner as to be rotated to directly hit the underside of the filter support frame.

According to the present inventive concept, desirably, while an extension direction of the filter support frame and an extension direction of a shaft connected to the hitting means are being disposed in parallel to each other, the hitting means hits the filter support frame.

According to the present inventive concept, desirably, while an extension direction of the filter support frame and an extension direction of a shaft connected to the hitting means are being disposed perpendicular to each other, the hitting means hits the filter support frame.

According to the present inventive concept, desirably, the pedal part includes: a pedal member having a vertical reciprocation motion with the external force applied thereto; and first power transmission means having at least one or more rack gears and at least one or more pinion gears to convert the vertical reciprocation motion of the pedal member into a rotary motion.

According to the present inventive concept, desirably, the pedal part includes: a pedal member having a vertical reciprocation motion with the external force applied thereto; and flow generation means having a link member rotatably connected to the pedal member to convert the vertical reciprocation motion of the pedal member into a linear reciprocation motion and a piston member connected to the link member in such a manner as to be operated by the operation of the pedal member.

According to the present inventive concept, desirably, the oil-water separator further includes a valve part coupled to a through hole formed at the center of the filter member to discharge the oil separated with delay through the filter member to the outside.

According to the present inventive concept, desirably, the valve part includes: a valve unit whose one end is inserted into the through hole of the filter member; a first impact absorbing part made of an elastic material and disposed between an outer periphery of the through hole of the filter member and an outer periphery of one end of the valve unit inserted into the through hole to decrease the external force applied to the valve unit and simultaneously to improve a coupling force between the filter member and one end of the valve unit; and an oil discharge pipe disposed on the other end of the valve unit to discharge the oil to the outside.

According to the present inventive concept, desirably, the valve unit includes an opening and closing lever extended therefrom in such a manner as to be passed through the outer casing so as to adjust an amount of oil discharged to the oil discharge pipe, and the valve part further includes a second impact absorbing part disposed on the outer casing at a position where the opening and closing lever and the outer casing come into contact with each other so as to absorb an impact applied to the valve unit at the time when the opening and closing lever is operated.

According to the present inventive concept, desirably, the oil-water separator further includes a filter cleaning part rotatably disposed in the outer casing in such a manner as to remove foreign matters attached to the filter member to filter the oil and the water at different speeds from each other.

According to the present inventive concept, desirably, the filter cleaning part includes: a cleaning body disposed on top of the filter member in such a manner as to have a shape capable of covering a top periphery of the filter member; at least one or more brush members detachably mounted onto the underside of the cleaning body in such a manner as to be frictional with the top of the filter member; and one pair of handles disposed protruding from the outer periphery of the cleaning body, seated on the top end periphery of the outer casing to allow the cleaning body to be rotatable in the outer casing, and exposed to the outside in such a manner as to be grasped by a user.

According to the present inventive concept, desirably, the outer casing further includes at least one pair of movement guide parts formed to a shape of ‘’ on the top end periphery thereof along moving paths of the handles to allow the handles to be rotatable.

According to the present inventive concept, desirably, the cleaning body is formed unitarily with the handles.
