[0034] like Figure 1 and Figure 2 As shown, the discharge assembly 40 includes an oil discharge assembly 41 , a water discharge assembly 42 and a sewage discharge assembly 43 . The oil discharge assembly 41 is inserted at the top of the upper cover 25 , and the water discharge assembly 42 and the sewage discharge assembly 43 are both inserted at the bottom of the separation shell 21 .

[0035] like Figure 1 and Figure 2 As shown, the oil drain assembly 41 includes an oil drain pipe 410 and an oil drain switch 411.

[0036] During installation: the oil-water separator 20 is installed on the top of the supporting assembly 10, the separation shell 21 is fixedly installed on the top of the supporting assembly 10, the first filter assembly 22 and the second filter assembly 23 are both installed inside the separation shell 21, the fixed base 230 is installed at one end of the bottom of the separation shell 21, the two annular second filter screens 231 are both installed on the top of the fixed base 230, the two ends of the scraper 241 are fixedly installed at the two ends of the second filter screen 231, the starting member 242, the two spring members 243 and the switch member 244 are all installed inside the second filter screen 231, the starting member 242 is slidably installed on the bottom side wall of the second filter screen 231, and the switch member 244 is installed on the bottom side wall of the second filter screen 231.

[0037] During use: 1. A water storage space is formed between the support plate 220, the mud collecting plate 221 and the separation shell 21 (not shown in the figure), and the water inlet 30 is connected to the water storage space. The treated ship water becomes an oil-water mixture, which is discharged into the water storage space through the water inlet 30. The oil-water mixture enters the multiple first filter elements 222 through the water storage space. After the oil-water mixture enters the first filter element 222, it flows out through the first filter hole 225 and enters the interior of the separation shell 21. When the oil-water mixture enters the first filter element 222, part of the grease in the oil-water mixture will adhere to the traction line 223, and flow from the innermost first filter hole 225 to the outermost first filter hole 225 under the traction of the traction line 223. During this period, the traction lines 223 are overlapped with each other, and the two overlapped traction lines 223 gather the grease together, so that the volume of the grease increases, and finally flows into the separation shell 21 from the outermost first filter hole 225.

[0038] 2. One end of the drainage component 42 is inserted into the bottom of the separation shell 21, and the other end is connected to a pump. The oil-water mixture flows into the separation shell 21. When the pump is pumping water, the oil-water mixture in the separation shell 21 will pass through the second filter screen 231, remove grease and tiny particles, and then flow into the drainage component 42, so that the oil-water mixture is clean. When the oil-water mixture in the separation shell 21 contacts the second filter screen 231, the grease passing through the first filter hole 225 is large, and the diameter of the second filter hole 232 of the second filter screen 231 is reduced, and the grease in the oil-water mixture cannot pass through the second filter. The hole 232 enters the second filter screen 231. Since the density of oil is less than that of water, grease accumulates on the top of the separation shell 21. The tiny particles hit the second filter screen 231 and fall on the bottom plate of the separation shell 21. A part of them falls directly into the sludge receiving tank 210, and the other part falls on the support plate 220. The support plate 220 shakes during operation, and the particles that fall on the support plate 220 can be shaken into the sludge receiving tank 210. The particles that fall into the sludge receiving tank 210 are discharged through the sewage pipe (430), and the grease on the top of the separation shell 21 is discharged through the oil drain pipe (410).

[0039] 3. Under long-term operation, grease and tiny particles will clog the second filter hole 232 of the second filter screen 231, causing the pressure of the water pump to rise and the suction to increase. The wind plate 260 on the starting member 242 will be attracted by the suction of the water pump and move downward. The starting block 261 moves downward following the wind plate 260 to squeeze the switch member 244. The switch member 244 is started, and the sliding block 251 moves up and down on the slide rail 250. The scraper brush moves up and down following the sliding block 251 to clean the grease and tiny particles clogged on the second filter screen 231, dredge the second filter hole 232, and prevent the second filter hole 232 from being blocked.

[0040] The present invention sets a traction line 223. When the oil-water mixture is discharged into the water storage space through the water inlet member 30, the oil-water mixture enters into multiple first filter elements 222 through the water storage space. After the oil-water mixture enters the first filter element 222, it flows out through the first filter hole 225 and enters the interior of the separation shell 21. When the oil-water mixture enters the first filter element 222, part of the grease in the oil-water mixture will adhere to the traction line 223, and flow from the innermost first filter hole 225 to the outermost first filter hole 225 under the traction of the traction line 223. During this period, the traction lines 223 are overlapped with each other. The two overlapped traction lines 223 gather the grease together, so that the volume of the grease increases, and finally flows into the separation shell 21 from the outermost first filter hole 225. By setting the second filter hole 232, when the water pump is pumping water, the oil-water mixture in the separation shell 21 will pass through the second filter screen 231, remove the grease and tiny particles, and then flow into the drainage component 42, so that the oil-water mixture is clean. When the oil-water mixture in the separation shell 21 contacts the second filter screen 231, the volume of grease passing through the first filter hole 225 is large, and the diameter of the second filter hole 232 of the second filter screen 231 is reduced. The grease in the oil-water mixture cannot pass through the second filter hole 232 to enter the second filter screen 231. Since the density of oil is less than that of water, the grease accumulates on the top of the separation shell 21, and the tiny particles hit the second filter screen 231 and fall on the bottom plate of the separation shell 21. A part of it falls directly into the sludge receiving tank 210, and the other part falls on the support plate 220. The support plate 220 shakes during operation, which can shake the particles falling on the support plate 220 into the sludge receiving tank 210. By setting the starter 242, under long-term operation, grease and tiny particles will block the second filter hole 232 of the second filter 231, so that the pressure of the water pump increases, the suction force becomes larger, and the wind plate 260 on the starter 242 will be attracted by the suction force of the water pump to move downward, and the starter block 261 moves downward with the wind plate 260 to squeeze the switch 244, and the switch 244 is started, and the sliding block 251 moves up and down on the slide rail 250, and the scraper brush moves up and down with the sliding block 251 to clean the grease and tiny particles blocked on the second filter 231, dredge the second filter hole 232, and prevent the second filter hole 232 from being blocked. The present invention has an ingenious structure, can well separate grease and particles in water, and can automatically clean the filter when the filter is blocked, thereby extending the service life of the equipment and reducing maintenance costs.

[0041] All possible combinations of the various technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
