After the protrusions 42 and the slide bars 22 are aligned with the mounting grooves 43, the protrusions 42 and the slide bars 22 are inserted into the mounting grooves 43, so that the first closing plate 21 and the second closing plate 23 line the inner end wall of the box body 11.

[0023] Advantageously, a plurality of studs 41 are provided on the right side of the box body 11, a plurality of through holes are provided in the flange 12 and the third closing plate 13, the studs 41 pass through the through holes, nuts and washers are provided on the outer surface of the studs 41, and the nuts and washers are abutted against the right side of the third closing plate 13 to maintain the airtightness of the box body 11.

[0024] Advantageously, it also includes an upper connecting pipe 52 and a lower connecting pipe 53. When four box bodies 11 are provided, an upper connecting pipe 52 is provided between the upper box bodies 11, the upper connecting pipe 52 is connected between the upper connecting ports 15 of the upper box bodies 11, the lower connecting pipe 53 is connected to one end of the lower connecting port 14 on one side of the upper box body 11, and the lower connecting pipe 53 is connected to one end of the upper connecting port 15 on one side of the lower box body 11. The upper connecting pipe 52 connects the interiors of the two upper box bodies 11, and the lower connecting pipe 53 connects the interiors of the upper and lower box bodies 11.

[0025] Advantageously, an upper flange 51 and a lower flange 54 are respectively disposed at the upper and lower ends of one side of the box body 11, and the upper flange 51 and the lower flange 54 can be communicated with an external space pipeline.

[0026] During modular assembly, the first closing plate 21 is inserted into the box body 11 so that the protrusion 42 is engaged with the mounting groove 43, and then the second closing plate 23 is slid into the box body 11 so that the second closing plate 23 is abutted against the first closing plate 21, and the slide bar 22 is inserted into the mounting groove 43. Thereafter, the third closing plate 13 is snap-fitted and installed on one side of the flange 12, and the stud 41 passes through the flange 12 and the third closing plate 13, and the third closing plate 13 is connected and fixed to the stud 41.

[0027] The upper flange 51 is used to allow accidental oil to flow in, and the lower flange 54 can be used to drain the lower layer of liquid in the box body 11 .

[0028] After the hydraulic cylinder 35 is pushed to work, the hinge rod 32 is driven to swing, so that the fourth closing plate 33 is telescopically moved inside, and the fourth closing plate 33 has the function of closing and opening the connecting groove 24, and further controls the on-off control of the upper connecting port 15 and the lower connecting port 14 and the connecting groove 24.

[0029] When four boxes 11 are provided, an upper connecting pipe 52 can be provided to connect the two upper boxes 11 to facilitate processing when a large flow of oil and water enters. At this time, the upper connecting port 15 needs to be connected to the upper connecting pipe 52.

[0030] By providing the lower connecting pipe 53 , the upper and lower tanks 11 are connected to each other, so that the oil and water in the upper tank 11 can be discharged into the lower tank 11 for processing.

[0031] Since the lower connecting pipe 53 is connected to the lower connecting port 14 of the upper box 11, more water in the lower layer of the box 11 enters the lower box 11 for centralized treatment.

[0032] When the box 11 processes oil and water separately, a pipeline is connected through the upper flange 51 and the lower flange 54. The upper flange 51 allows the oil and water to be processed to pass through, and the lower flange 54 is connected to the pipeline for discharging the oil or water. When the oil and water in the box 11 are stratified, the bottom layer of water is discharged by the lower flange 54, and then the oil in the box 11 is discharged. When receiving the water and oil, different containers can be set up to receive them.

[0033] When multiple boxes 11 are provided, valves can be connected to the upper flange 51 and the lower flange 54 where oil or water does not need to be discharged or discharged, so as to close the upper flange 51 and the lower flange 54 and prevent the oil and water from being discharged.

[0034] The above are only specific implementations of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
