Like this, when oil water separator installs on the liquid case, through the starter motor, can drive the shaft coupling and rotate, and then the pivot also can rotate thereupon. The rotating shaft and the helical blade form relative motion. Because the helical blade has a certain length, the helical blade has certain flexibility, and when the rotating shaft is embedded in the helical blade, the helical blade can be in discontinuous contact. Therefore, the floating oil adhered to the rotating shaft can form an oil film through the contact between the rotating shaft and the helical blade, and the oil film gradually ascends along the helical blade under the rotation of the rotating shaft until the oil film is brought into the oil discharging sleeve by the rotating shaft and the helical blade. Because the screw thread of unloading the oil jacket is opened there is the oil discharge mouth in, and the crossing breach that forms of screw thread and oil discharge mouth department at the oil discharge mouth for the oil film disconnection, the oil slick can be along with in the oil discharge mouth flows into the recess of mount pad, is scraped to the oil drain port along with pivot pivoted oil scraping plate and discharges. Impurity particles in the oil stain are blocked by the helical blade when the rotating shaft rotates, and the surface formed by the helical blade structure is an inclined structure, so that the particle impurities can be effectively prevented from rising along with oil, and can slide off from the surface of the helical blade under the action of gravity (shown in a figure 5). This avoids interference or clogging of the oil discharge passage by particulate impurities.

It should be noted that the rotating shaft and the helical blade can be made of oleophilic and hydrophobic materials, and in order to reduce weight, the rotating shaft is also used as a hollow structure. In order to improve the oil removing efficiency, the length of the rotating shaft is larger than that of the helical blade, and optimally, the rotating shaft entering the liquid surface is arranged to protrude out of the helical blade.

The application has no consumable material and is maintenance-free, and the labor cost generated by equipment maintenance can be effectively reduced while the occupied area is reduced.

The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
