Detailed Description

Specific embodiments of the present utility model will be described below with reference to the accompanying drawings. As shown in fig. 1 to 4: the utility model provides an overflow oil recovery oil water separator, it includes a main tank 1 as basis, the inner chamber of this main tank 1 is separated into first chamber 4 by first baffle 2 and second baffle 3 that are parallel to each other, second chamber 5 and third chamber 6, be provided with filter screen 7 in the first chamber 4, be provided with the entry pipeline 8 that links to each other with filter screen 7 inside on the lateral wall of main tank 1 simultaneously, all offered on first baffle 2 and the second baffle 3 and crossed the mouth 9 on the first baffle 2 and crossed the mouth 9 on the second baffle 3 and are located the both ends of main tank 1 width direction respectively, be provided with liquid level sensor 10 and lower liquid level sensor 11 in the third chamber 6 simultaneously, still be provided with liquid level window 12 on the lateral wall of third chamber 6 simultaneously on main tank 1 still be provided with drain line 13, manual drain line 14, drain line 15 and manual drain line 16 that are linked together with third chamber 6, manual drain line 14 and manual drain line 16 are provided with drain valve 17 on the manual drain line 15, manual drain line 16 is provided with drain valve 15,

The working process of the spilled oil recovery oil-water separation device provided by the embodiment of the utility model is as follows: when oil spills on the sea surface and oil floating on the sea surface is needed to be recovered, the oil-water mixture is pumped into the main tank body 1 of the device by utilizing the shipborne pump body, in particular, the oil-water mixture is directly pumped to the inlet pipeline 8, the oil-water mixture enters the filter screen 7 through the inlet pipeline 8 and is filtered at the inlet pipeline, some solid impurities in the oil-water mixture are trapped at the filter screen 7, the oil-water mixture with the solid impurities removed can fall into the first cavity 4 below the filter screen 7, and flows into the third cavity 6 through the through-flow opening 9 arranged on the first partition plate 2 and the second partition plate 3, and as the through-flow opening 9 on the first partition plate 2 and the through-flow opening 9 on the second partition plate 3 are respectively positioned at two ends of the width direction of the main tank body 1, namely, the flow track of the oil-water mixture is in a serpentine shape in the process of entering the third cavity 6 from the first cavity 4 through the second cavity 5, the structure can prevent the oil-water mixture entering the third cavity 6 from impacting the mixed liquid in the third cavity 6, so that the oil-water mixture in the third cavity 6 is more stable and is in a natural fluctuation state in the third cavity 6;

the upper liquid level sensor 10 and the lower liquid level sensor 11 which are arranged in the third cavity 6 are radio frequency admittance liquid level switch sensors, when a probe in the sensor is positioned in air and oil, no voltage signal is output, and when the probe is positioned in water, the voltage signal is output; that is, it can directly detect the water level in the layered oil-water mixture;

the oil-water mixture in the third cavity 6 is naturally layered after standing for a period of time, oil is arranged at the upper layer and water is arranged at the lower layer, the oil layer and the water layer are gradually raised along with the continuous increase of the oil-water mixture, when the liquid level of the oil reaches the height of the oil discharge pipeline 13, the oil at the uppermost layer can be automatically discharged through the normally open oil discharge pipeline 13, and the pipeline connected to the oil discharge pipeline 13 can guide the oil into the oil collecting container for storage;

when the oil-water interface contacts the lower liquid level sensor 11, the lower liquid level sensor 11 outputs a voltage signal to a shipborne control system, the control system can control the electromagnetic valve 18 on the drainage pipeline 15 to be half-opened, the drainage pipeline 15 starts to drain, and the water level is lowered; if the oil-water interface contacts the upper liquid level sensor 10, the upper liquid level sensor 10 outputs a voltage signal to a control system, and the control system can control the electromagnetic valve 18 on the drainage pipeline 15 to be fully opened, so that the drainage pipeline 15 can drain water rapidly, and the water level can drop rapidly; according to the design, the oil-water interface is always in the height range between the two sensors through the two liquid level sensors with the height difference, and the electromagnetic valve 18 is not required to be in a frequently opened and closed state, so that the failure rate of the device is reduced, and the reliability is improved;

if only one liquid level sensor is adopted, when the water inflow is smaller than the water outlet displacement, the oil-water interface can be rapidly reduced, and the electromagnetic valve 18 needs to be closed immediately, so that frequent start and stop can occur, and the service life of the electromagnetic valve 18 is reduced; when the water inflow is larger than the water outlet displacement, seawater enters the oil outlet when the oil-water interface rises to the oil outlet, and the purpose of oil-water separation cannot be achieved.

In the working process, a worker can observe the water level in the third cavity 6 from the side direction through the liquid level window 12, can open the check cover 22, observe the condition in the filter screen 7, and remove solid impurities in the filter screen 7 through the check window;

when all the liquid in the main tank 1 needs to be discharged to clean or overhaul the main tank 1, the manual valve 17 on the manual oil drain pipeline 14 can be opened first to drain the oil on the upper layer, and then the manual valve 17 on the manual water drain pipeline 16 can be opened to drain the residual oil-water mixture.
