[0035] In summary, the working process of the oil-water separator is as follows: before use, the fixed mounting plate 26 is first fixed at the installation site to achieve the vertical installation of the oil-water separator at the use site; during use, the oil-water to be treated is pressed into the communication pipe 1 through the guide pipe 25 and is given a certain pressure, so that the highest liquid level of the oil-water is higher than the filter cap 11 and lower than the highest position of the oil collecting ring 12; in this process, because the oil is above the water due to the different densities of the oil and the water, the oil in the oil-water enters the area formed by the filter cap 11 and the supporting ring 10 of the oil collecting ring 12, and then is discharged through the oil discharge pipe 13; at the same time, the water in the oil-water is below the oil due to the density, and thus flows out through the area between the sleeve 9 and the converging cylinder 7, enters the area between the guide cylinder 6 and the mounting pipe 2, and is finally discharged through the drain pipe 4; at the same time, during the oil-water separation process, the converging cylinder 7 and the supporting ring 10 with different height differences can be selected according to the specific proportion of the oil-water; when the oil in the oil-water is too much and the first separation effect is not good, the oil-water not completely separated and discharged from the drain pipe 4 can be guided to flow back into the communication pipe 1 to achieve secondary treatment, thereby improving the oil-water separation effect; and during the treatment process, the liquid level height of the oil-water in the mounting pipe 2 is maintained to ensure the continuous treatment of the oil-water.

[0036] Further, when the oil-water separation treatment reaches a stage and needs to be stopped for correction or maintenance, the pressurization of the guide pipe 25 is stopped, and under the action of the self-gravity of the oil-water, the oil-water in the mounting pipe 2 flows back outward, and the liquid level height of the oil-water is lowered; during maintenance or cleaning, only the cover plate 15 needs to be removed; at the same time, when the separation filter needs to be removed for cleaning or replacement, only the connection screw 16 relative to the supporting cylinder 8 needs to be removed after the oil discharge pipe 13 is removed by first rotating the sealing cap 21; when the filter screen 14 needs to be removed for cleaning or replacement, only the connection between the connection flange plate 3 and the mounting flange plate 5 needs to be disabled, and then the mounting pipe 2 can be removed relative to the communication pipe 1; in this state, the filter screen 14 can be exposed, and the removal of the filter screen 14 can be achieved by removing the connection screw 24 pressing the filter screen 14; at the same time, the installation and resetting of the cleaned separation filter and filter screen 14 can be achieved by reversing the above steps, and the operation is relatively simple; at the same time, the separation filter is integrally injection molded, which can better improve the production efficiency and reduce the maintenance cost of the entire use cycle of the oil-water separator.
