As shown in fig. 1 to 5, the present embodiment provides an oil skimmer, which may be applied to a kitchen of a marine vessel, and includes a tank 1, a filter assembly 2, and an oil skimmer assembly 3.

Referring to fig. 1, a water inlet 11 and a water outlet 12 are arranged on the box body 1, the water inlet 11 is located at the left end of the box body 1 near the top of the box body 1, and the water outlet 12 is located at the middle position of the right end of the box body 1. The filter assembly 2 is located at one end of the tank 1 near the water inlet 11, so that the grey water entering the tank 1 flows through the filter assembly 2 first to filter impurities in the grey water. The oil skimming component 3 comprises a first oil skimming plate 31 and a second oil skimming plate 32 which are arranged in the box body 1 at intervals, one ends of the first oil skimming plate 31 and the second oil skimming plate 32 are connected with the bottom of the box body 1, and the other ends of the first oil skimming plate 31 and the second oil skimming plate 32 extend upwards vertically. The first oil skimming plate 31 can separate grease in grey water, the grey water containing grease enters the box body 1 through the water inlet 11 and sequentially flows through the filtering component 2, the first oil skimming plate 31 and the second oil skimming plate 32 to separate impurities and grease in the grey water, and the filtered grey water flows out of the box body 1 through the water outlet 12.

In this embodiment, the water inlet 11 and the water outlet 12 are both provided with a first flange connection plate, and the grey water discharge pipe and the water inlet pipe of the sewage treatment device are both provided with a second flange connection plate. When the oil skimming device is installed, a second flange connecting plate of a grey water drain pipe is connected with a first flange connecting plate of a water inlet 11 of the oil skimming device, and a second flange connecting plate of a water inlet pipe of a sewage treatment device is connected with a first flange connecting plate of a water outlet 12 of the oil skimming device. The grey water entering the box body 1 through the water inlet 11 flows through the filtering component 2 firstly to filter large particle impurities in the grey water, so that the large particle impurities are prevented from blocking a pipeline, the amount of residues deposited at the bottom of the box body 1 can be reduced, and the residues in the box body 1 in the later period can be cleaned conveniently. The grey water filtered by the filtering component 2 sequentially flows through the first oil skimming plate 31 and the second oil skimming plate 32 to skimming grease carried in the grey water, so that a good oil skimming effect is achieved. The grey water after grease separation flows out of the box body 1 through the water outlet 12 and is introduced into the sewage treatment device for collection and storage. Compare oil skimmer among the prior art, the oil skimmer of this embodiment does not set up blow vent, oil pipe etc. has simplified the outside pipeline connection structure of oil skimmer, saves occupation of land space, and is simpler during the installation.

Optionally, the first oil skimming plate 31 has a first area, the first area is located at one end of the first oil skimming plate 31 close to the bottom of the tank 1, and a plurality of first through holes 311 are arranged in the first area. That is, as shown in fig. 2, the first area is located at the lower end of the first oil skimming plate 31, the plurality of first through holes 311 are distributed in an array in the first area, and the grey water can flow through the first oil skimming plate 31 through the plurality of first through holes 311. Since the density of the grease is less than that of the water, grease carried in the grey water will float on the surface of the grey water. Moreover, since the plurality of first through holes 311 are disposed at the bottom end of the first oil skimming plate 31, when the grey water flows through the first oil skimming plate 31 via the plurality of first through holes 311, grease floating on the surface of the grey water is blocked at the upper end of the first oil skimming plate 31 on the side opposite to the second oil skimming plate 32, so as to achieve the effect of separating grease in the grey water.

Further, since the plurality of first through holes 311 are located at the lower end of the first oil skimmer plate 31 and the water inlet 11 is located at the upper end of the case 1, i.e., the position of the water inlet 11 is higher than the position of the plurality of first through holes 311. Therefore, when the grey water is at a static liquid level, the grey water carrying grease cannot directly flow through the plurality of first through holes 311, and the first oil skimming plate 31 can also achieve a good oil skimming effect.

Optionally, the second oil skimming plate 32 has a second area, the second area is opposite to the water outlet 12, a plurality of second through holes 321 are arranged in the second area, and the grey water flows through the second oil skimming plate 32 through the plurality of second through holes 321. As shown in fig. 3, the second region is located in the middle of the second oil skimming plate 32, and a plurality of second through holes 321 are distributed in the second region in an array. Because the plurality of second through holes 321 are opposite to the water outlet 12, the second oil skimming plate 32 can guide the grey water after grease separation, so that the grey water can smoothly flow out through the water outlet 12. In addition, the plurality of second through holes 321 on the second oil skimming plate 32 can also play a role in secondary filtration, and reduce impurities in the grey water.

Alternatively, referring to FIG. 1, the first oil skimming plate 31 and the second oil skimming plate 32 separate a first chamber 33, a second chamber 34 and a third chamber 35 within the housing 1, the water inlet 11 is in communication with the first chamber 33, the filter assembly 2 is located within the first chamber 33, and the grey water entering the housing 1 is first filtered by the filter assembly 2 to remove large particulate impurities. The first chamber 33 is communicated with the second chamber 34 through the plurality of first through holes 311 on the first oil skimming plate 31, the grey water filtered by the filtering assembly 2 flows into the second chamber 34 through the plurality of first through holes 311, and simultaneously the first oil skimming plate 31 separates grease in the grey water to block the grease on the side of the first oil skimming plate 31 opposite to the second oil skimming plate 32. The second chamber 34 is communicated with the third chamber 35 through a plurality of second through holes 321 on the second oil skimming plate 32, and the grey water after grease separation flows into the third chamber 35 through the plurality of second through holes 321 and then flows into the sewage treatment device through the water outlet 12.
