Description

Floating oil recovery device of floating oil recovery ship

Technical Field

The utility model relates to an oil-water separation technique, especially a floating oil recovery ship retrieves oil slick device.

Background

It is well known that petroleum is an important strategic material in the world at present, and most of the trade of petroleum among countries is transported on the sea. The tonnage of a ship for transporting crude oil is getting larger and larger, and once a crude oil leakage accident occurs, the leaked crude oil floats on a wide sea surface, so that serious damage is brought to marine organisms and the surrounding environment.

At present, a recovery device of a floating oil recovery ship for recovering floating oil on the sea comprises an oil suction pump and an oil-water separator. And (3) pumping the floating oil on the sea surface by using an oil suction pump, then carrying out oil-water separation by using an oil-water separator, and collecting the separated floating oil in an oil storage cabin. The recovery device has the advantages of complex structure and high cost, and can extract seawater together when the oil absorption pump extracts floating oil, and then separate the water by the oil-water separator, so the flow is long, and the floating oil recovery efficiency is low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a ship recovery oil slick device is retrieved to simple structure, tall oil slick recovery efficiency.

The utility model provides a floating oil recovery device of a floating oil recovery ship, which comprises a rotating frame, a hydraulic rod, an oil-water separation device, a scraper and an oil storage cabin;

the rotating frame is a U-shaped groove, and the bottom of the rotating frame is hinged with the front edge of a deck of the ship body through a hinge support; the hydraulic rod is arranged on a deck of the ship body, and the upper end of the hydraulic rod is hinged with the rear part of the side wall of the rotating frame; the oil-water separation device comprises a conveyor belt, the outer surface of the conveyor belt is provided with a brush, the conveyor belt is driven by a hydraulic motor arranged on a ship through a transmission wheel, and a front transmission wheel and a rear transmission wheel are respectively arranged at two ends of the bottom of a U-shaped groove of the rotating frame; the lower part of one end, close to the cockpit, of the scraper corresponding to the conveyor belt is arranged at the rear ends of two side walls of the rotating frame and is in contact with the hairbrush on the conveyor belt; the oil storage tank is arranged in the ship body corresponding to the scraper and used for collecting floating oil scraped by the scraper.

The utility model discloses when the oil recovery ship normally navigates, the hydraulic stem is in the contraction state, and the rotating turret level was placed on the deck this moment, retrieves the oil slick device and sea water contactless, out of work. During the deoiling, the hydraulic stem stretches out, with the turret rear end (being close to cockpit one end) jack-up that makes progress, the turret front end (keep away from cockpit one end) inserts the surface of water under, the conveyer belt front end sinks simultaneously under the surface of water, hydraulic motor drive conveyer belt anticlockwise rotates this moment, the crude oil that floats on the surface of water is by the brush adhesion on the conveyer belt, because the brush only viscous oil is not the viscous water, the oil slick that is followed the brush adhesion breaks away from the sea water along with the rising of conveyer belt, the upper end of running to the conveyer belt is scraped by the scraper blade, fall into the oil storage tank of setting in the hull. The recovery ship moves back and forth on the sea surface floating with crude oil, and floating oil on the whole sea area can be collected completely.

Compared with the prior art, the beneficial effects of the utility model are that:

1. the utility model discloses regard as its oil-water separator with the conveyer belt that has the brush, replace original oil suction pump + oil-water separator with it, make the structure of retrieving the oil slick device greatly simplify, be favorable to reducing the manufacturing cost of oil slick recovery ship, and make things convenient for equipment maintenance.

2. The utility model discloses utilize the brush only to glue oil, the characteristic of non-stick water directly to draw out the oil slick from the sea water, need not pass through the complicated process of absorbing oil water mixture, passing through oil water separator separation again by the oil absorption pump, make the oil water separation process become extremely simple to make oil slick recovery efficiency obtain improving.

3. Because the whole conveying belt is full of the brushes for adhering the floating oil, even if the ship body floats up and down on the sea surface, the phenomenon that the brushes are separated from the water surface can not occur, and the brushes are always in an automatic floating oil collecting state.
