[0038] A plurality of oil skimming plates 4 are arranged on the connecting shaft 3 from left to right at intervals, and the top of each oil skimming plate 4 passes through a longitudinal through groove 2 and is arranged above the top surface of the mounting plate 1;

[0039] A driving member is arranged on the mounting plate 1, and the driving member drives the connecting shaft 3 to rotate;

[0040] An oil scraping plate 5 is arranged on the top surface of the mounting plate 1, and the oil scraping plate 5 is arranged on the top surface of the mounting plate 1 at the front end of the connecting shaft 3. One oil scraping plate 5 is arranged on each side of each oil skimming plate 4, and the inner side wall of the oil scraping plate 5 is in contact with the outer side wall of the front end of the oil skimming plate 4. In this embodiment, the oil scraping plate is made of rubber to prevent rigid contact with the oil skimming plate and to ensure the quality of oil scraping.

[0041] In this embodiment, the top surface of the mounting plate is arranged to be inclined downward from back to front. In use, the oil skimming plates below the mounting plate are immersed in the oil-water mixture, mainly in the oil floating on the water layer (the oil floats on the water surface due to the different specific gravities of oil and water). The connecting shaft drives the rotation of all the oil skimming plates, and the top of the oil skimming plate rotates forward. The oil skimming plate is made of an oleophilic material, the width of the longitudinal through groove is greater than the thickness of the oil skimming plate, and the oil skimming plate is located at the center of the longitudinal through groove. When the oil skimming plate rotates, the oil adheres to the side walls on both sides of the oil skimming plate. The oil scraping plate is located in front of the axis of the oil skimming plate. Therefore, when the oil skimming plate with adhered oil rotates upward from the rear end of the longitudinal through groove to above the mounting plate and then rotates to the top with the front end downward, the two sides of the oil skimming plate come into contact with the two oil scraping plates, and the oil scraping plates scrape off the oil on the side walls on both sides of the front end of the oil skimming plate and are located on the oil scraping plates. Due to the inclined downward arrangement of the top surface of the mounting plate from back to front, the oil scraping plate is also arranged to be inclined downward from back to front, and the oil on the oil scraping plate moves forward under the action of gravity and flows out of the mounting plate, thereby quickly cleaning the oil in the oil-water mixture and improving the efficiency and effect of oil-water separation. In this embodiment, a plurality of oil skimming plates are arranged to effectively increase the contact area with the oil and improve the efficiency and effect of oil skimming and the efficiency and effect of oil-water separation.

Meanwhile, when the oil skimming disc rotates, the oil skimming disc gives a downward pressing force to the oil scraping plate, so that the oil scraping plate does not need to be limited by bolts penetrating into the oil scraping plate, but only needs to be limited by pressing the oil scraping plate on the mounting plate, and in this structure, the contact force between the oil scraping plate and the oil skimming disc can be adjusted (the oil scraping plate is moved horizontally, and the distance between the outer end of the oil scraping plate and the oil skimming disc is adjusted to adjust the contact force between the two), so that the oil scraping plate can stably scrape off the oil on the side wall of the oil skimming disc.

[0045] Referring to Figure 4 As shown in the figure, the inner end of the oil scraping plate 5 is arranged to be inclined upward from outside to inside. The inner end of the oil scraping plate is arranged to be inclined, and the oil scraping plate forms an acute angle with the rotating direction of the oil skimming disc, so that the friction force between the oil skimming disc and the oil scraping plate can be reduced, and the scraping effect and quality can be ensured. At the same time, the friction force of the oil scraping plate on the oil skimming disc is reduced, the driving force requirement of the driving member is reduced, the power and size requirements of the driving member are reduced, and the cost is also lower.

And, because two groups of drive motors are adopted, the size of the whole oil water separator can be set smaller, and the space occupation is smaller. And, the drive motor is arranged on the mounting plate, and the maintenance and replacement of the drive motor are facilitated.

[0048] In the embodiment, bearing seats are arranged at the two sides of the bottom of the mounting plate, and the two ends of the connecting shaft are rotatably connected with the bearing seats through the bearings.

[0049] Referring to Figures 5-7 The utility model discloses still provide an oil water separator, including the box 20, be equipped with oil water separation cavity 21 in the box 20, be equipped with the liquid inlet 22, water outlet 23 and oil outlet 24 of oil water separation cavity 21 communication on the box 20,

[0050] The liquid inlet 22 is arranged at the right upper side of the box 20, the water outlet 23 is arranged at the left side of the box 20, and the oil outlet 24 is arranged on the front side wall of the box 20.

[0051] The oil water separation cavity 21 is provided with a plurality of partitions, and the plurality of partitions are arranged between the liquid inlet and the water outlet from left to right.

[0052] Further comprising the oil scraping device, the oil scraping device is arranged in the oil water separation cavity, the mounting plate 1 is installed above the plurality of partitions, the oil water separation cavity in the front side of the mounting plate 1 is further provided with an oil collecting bucket 25, the rear end of the oil collecting bucket 25 is connected with the front end of the partition, the front end of the oil collecting bucket 25 is connected with the inner wall of the front side of the oil water separation cavity 21, and the oil outlet 24 is communicated with the oil collecting bucket 25.

[0053] In this embodiment, the partition includes three upper partitions 26 and two lower partitions 27. The three upper partitions are spaced apart from each other on the left and right. The front end and rear end of the two upper partitions are fixedly connected to the front side wall and rear side wall of the oil-water separation chamber, respectively. The top of the upper partition is located close to the bottom surface of the mounting plate. There is a vertical gap between the bottom of the upper partition and the bottom surface of the oil-water separation chamber. The top of the front end of the upper partition abuts against the bottom surface of the oil collecting hopper. The front end of the mounting plate is fixedly connected to the rear end of the oil collecting hopper. The bottom rear side of the mounting plate is fixedly connected to the top of the two upper partitions via a bracket. Each lower partition is positioned between two adjacent upper partitions, with the lower partition closer to the upper partition on the right. The front and rear ends of the lower partition are connected to the front and rear side walls of the oil-water separation chamber, respectively, and the bottom surface of the lower partition is connected to the bottom surface of the oil-water separation chamber. The top plane of the lower partition is positioned below the top plane of the upper partition. The planes of the liquid inlet, water outlet, and oil outlet are all positioned above the top plane of the lower partition, while the liquid inlet and water outlet are positioned below the top plane of the upper partition. The oil-water mixture enters the oil-water separation chamber through the inlet, then flows from the bottom of the rightmost upper baffle to the left, then from the top of the rightmost lower baffle to the left, then from the bottom of the middle upper baffle to the upper left, then from the top of the leftmost lower baffle to the left, and finally from the bottom of the leftmost upper baffle to the left, exiting through the outlet. Due to the difference in specific gravity between oil and water, the grease floats above the water. Four skimming plates are installed between the rightmost upper baffle and the right side wall of the oil-water separation chamber; three skimming plates are installed between the middle upper baffle and the right upper baffle; and two skimming plates are installed between the left upper baffle and the right upper baffle. The closer to the inlet, the higher the concentration of grease in the oil-water mixture, hence the greater number of skimming plates there are. The further to the left, the lower the concentration of grease. Therefore, this arrangement of skimming plates effectively improves the efficiency and effectiveness of oil-water separation. After the grease is scraped off by the scraper, it flows into the oil collection hopper, is collected, and is discharged directly through the oil outlet, ensuring the oil discharge effect. Moreover, the collected grease will not mix with the water, ensuring the oil-water separation effect.

[0054] See Figure 5 , 6 As shown, the front end of the oil scraper 5 is inserted into the oil collecting hopper 25. In this way, the grease flowing forward along the oil scraper can flow into the oil collecting hopper as much as possible, and it is prevented from flowing back into the oil-water separation chamber from the gap between the front end of the skimming plate and the longitudinal channel.

[0055] The bottom surface of the oil collecting hopper is inclined downwards from back to front. This ensures effective oil collection and facilitates the discharge of grease from the hopper through the drain port.

[0056] In this embodiment, a heating rod 28 is also installed inside the oil-water separation chamber to heat the oil-water mixture, prevent the oil from solidifying, and ensure the oil-water separation effect.
