Active oil gathering type marine oil-water separator for environmental protection

Abstract

The invention discloses an active oil gathering type marine oil-water separator for environmental protection. The active oil gathering type marine oil-water separator comprises an external positioning frame, a separation base, a telescopic ring sleeve, an oil gathering cover, a power unit and an oil discharging assembly. After oil-water mixed liquid enters a cavity defined by the separation base and the telescopic ring sleeve, oil floats upwards and is layered, the oil gathering cover is driven by the power unit to move, the suction pipe moves to the oil-water separation position, then the suction device is started, the oil is sucked through the suction pipe, and when the oil is sucked to the oil-water separation position, the oil is sucked into the oil-water separation position. The power unit drives the oil gathering cover to move downwards, the oil gathering cover drives the suction pipe to move downwards synchronously, oil liquid is gathered upwards through the downward movement of the oil gathering cover, thin oil layers can be gradually gathered upwards in the oil gathering cover to form thick oil layers, re-suction of the suction pipe is facilitated, and the space of the horizontal plane where the oil liquid is gathered is reduced, so that the oil gathering efficiency is improved. The oil liquid gathering thickness is increased, the suction convenience is improved, oil can be fully pumped out by reducing water pumping, and the use is flexible and convenient.

Description

Technical Field

[0001] The invention belongs to a marine oil-water separator, and in particular relates to an environmentally friendly active oil-collecting marine oil-water separator. Background Art

[0002] Engine room bilge water is oily sewage mixed with water leaked from various valves and pipes in the engine room, lubricating oil leaked from the machine during operation, fuel oil from the main and auxiliary engines, oil spilled during oil transfer, and oily sewage generated when washing the machinery and the anti-skid iron plates in the engine room. Engine room bilge water is prohibited from being discharged directly overboard, otherwise it will pollute the environment. It is generally collected into the sewage tank by a sewage pump, and then separated by an oil-water separator. The dirty oil is discharged into the dirty oil tank, and the clean water reaching the standard is discharged into the sea; when the existing oil-water separator is in use, the oil will float on the upper layer and the water will be located in the lower layer, so by suction The upper layer of oil can be extracted in this way, but after the oil is gradually sucked out and separated, there will eventually be a thin oil layer floating on the upper layer of water. It is difficult to extract and separate this very thin oil layer. If it is not sucked out, there will be residues, which will affect the environment and cause pollution. If a lot of water needs to be extracted at the same time to completely separate the oil layer, the storage space of the oil will be wasted, and the operation is more cumbersome. In order to improve the extraction efficiency and separation convenience of the thin oil layer, reduce unnecessary water extraction, and improve environmental protection, the structure needs to be upgraded and renovated. Summary of the Invention

[0003] In view of the above-mentioned shortcomings of the existing technology, the problem solved by the present invention is to provide an environmentally friendly active oil-collecting marine oil-water separator that can effectively, efficiently and conveniently pump oil, improve the separation effect of thin oil layers, achieve environmental protection and reduce pollution.

[0004] In order to solve the above problems, the technical solutions adopted by the present invention are as follows: The outer cover is fixedly mounted on the support frame, and the support frame is connected to the oil collecting cover to form a circle around the bottom cover of the oil collecting cover.

[0005] Furthermore, a supporting annular sleeve is provided around the lower side of the oil collecting hood; the supporting annular sleeve is located outside the four sides of the telescopic annular sleeve.

[0006] Furthermore, sliding tracks are respectively provided on both sides of the external positioning frame; a track block is provided in the sliding track, a power screw is rotatably connected in the sliding track, and the power screw is threadedly screwed to the track block; the power unit is a driving motor, and the lower end of the power screw is respectively connected to the power unit, and the power unit drives the power screw to rotate forward and reverse; the two sides of the oil collecting hood are respectively connected to the track blocks through connecting rods.

[0007] Furthermore, the outer end of the suction pipe and the inner end of the external liquid discharge pipe are telescopically connected via a stretching tube.

[0008] Furthermore, the oil collecting cover is a structure with a closed upper end and an open lower end; the oil collecting cover is a conical structure with a small upper end and a large lower end.

[0009] Furthermore, a drain pipe is provided on one side of the separation base; an opening and closing valve is provided on the drain pipe.

[0010] Furthermore, a liquid injection pipe is provided at the upper end of the oil collecting hood.

[0011] Furthermore, the telescopic ring is made of an elastic telescopic material or a bellows; and the inner side wall of the telescopic ring is coated with a corrosion-resistant coating.

[0012] The beneficial effects of the present invention are as follows: After the oil-water mixture of the present invention enters the cavity surrounded by the separation base and the telescopic ring, the oil will float upward. After stratification, the power unit drives the oil collecting hood to move, so that the suction pipe moves to the oil-water separation point, and then the suction device is turned on to extract the oil through the suction pipe. When the oil is extracted to the oil-water separation point, the power unit drives the oil collecting hood to move downward, and the oil collecting hood drives the suction pipe to move downward synchronously. The downward movement of the oil collecting hood causes the oil to converge upward, so that the thin oil layer can gradually converge upward into a thick oil layer in the oil collecting hood, which is convenient for re-suction by the suction pipe. In this way, the horizontal plane space where the oil converges is reduced, so that the thickness of the oil converges is increased, thereby improving the convenience of suction, reducing the extraction of water, and fully extracting the oil. It is flexible and convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS
