Like this, at blade 22 rotation in-process, the above-mentioned setting of cover body 40 can prevent to be stirred up by blade 22 and wait to separate the oil water mixture and splash to the environment and the polluted environment under the centrifugal action, has promoted user's use and has experienced. Meanwhile, the blade 22 is prevented from structurally interfering with the cover body 40 in the rotating process to cause structural damage due to the arrangement of the arc-shaped surface, and the structural reliability of the oil-water separation device is improved.
Specifically, the cover 40 includes a first cover plate, a second cover plate and an outer peripheral plate, the first cover plate and the second cover plate are parallel to each other and are connected together through the outer peripheral plate, the inner surface of the outer peripheral surface facing the separation structure 20 is an arc surface, and the first cover plate is disposed on the base 10. Wherein, the peripheral plate is the arc, and the pivot axis coaxial setting of arc and rotation part 21, and the central angle of arc is 180.
As shown in fig. 2, 3, and 5, the oil-water separator further includes a scraper 50. Wherein, at least part of the scraper 50 extends towards the rotating part 21, and in the process that the rotating part 21 drives the blades 22 to rotate, the scraper 50 is contacted with the surface of the blades 22 facing the scraper 50 so as to scrape off oil and metal scraps attached on the blades 22. Wherein at least a portion of scraper 50 is made of rubber or silicone. Like this, at blade 22 rotation in-process, blade 22 can contact with scraper blade 50, and scraper blade 50 will be attached to the fluid and the metal fillings on blade 22 and scrape down to collect fluid and metal fillings, realize the separation of water and fluid, promoted oil water separator's separation reliability. Meanwhile, the scraper 50 is of a flexible structure, after the scraper 50 scrapes off oil and metal scraps attached to the blades 22, the blades 22 continue to rotate, and the scraper 50 deforms to ensure that the next blade 22 can rotate to the position of the scraper 50, and the scraper 50 can contact with the surface of the blade 22 facing the scraper 50.
Specifically, during rotation of the blade 22, the scraper 50 contacts the second plate 222 to scrape off oil and metal chips attached to the second plate 222, thereby facilitating subsequent collection of the scraped oil and metal chips. After the oil and the metal chips on one blade 22 are scraped by the scraper 50, the scraper 50 is deformed under the pushing action of the blade 22 to ensure that the blade 22 can pass through the scraper 50 and then rotate continuously, and after the blade 22 passes through the scraper 50, the scraper 50 returns to the original shape to scrape the oil and the metal chips on the next blade 22 and circulate in sequence. Wherein, because the second plate 222 is made of resin, the impact force of the blade 22 on the scraper 50 can be reduced, and the service life of the blade 22 and the scraper 50 can be prolonged.
