[0031] Please refer to Figures 1-4 This utility model provides a compact oil-water separator, which is installed on the cover plate 1 of the machine tool water tank and includes a turntable 2, a turntable drive device 3, an oil scraping assembly 4 and a liquid collection tank 5.

[0032] The liquid collection tank 5 includes a turntable accommodating chamber 51, a buffer chamber 52, and an oil collection chamber 53. The buffer chamber 52 and the oil collection chamber 53 are arranged side by side and located on one side of the turntable accommodating chamber 51 in the X-axis direction. The side wall of the buffer chamber 52 near the turntable accommodating chamber 51 is provided with an overflow inlet 501. The cover plate 1 is provided with an installation port, and the liquid collection tank 5 is disposed in the installation port. The bottom of the turntable accommodating chamber 51 is connected to the machine tool water tank.

[0033] The turntable 2 is disposed in the turntable receiving chamber 51, and the lowest point of the turntable 2 passes through the turntable receiving chamber 51 and extends below the liquid surface in the machine tool water tank; the turntable drive device 3 is disposed on the other side of the turntable receiving chamber 51 in the X-axis direction; the output end of the turntable drive device 3 is disposed along the X-axis, passes through the turntable receiving chamber 51, and is connected to the turntable 2 in a transmission manner, so that the turntable rotates with the output end of the turntable drive device 3 as the rotation axis; the oil scraping assembly 4 is disposed in the turntable receiving chamber 51 and is used to guide the oily liquid on the turntable 2 to the oil collection chamber 53.

[0034] In a specific embodiment of this invention, the oily liquid is specifically cutting fluid. The oil-water separator utilizes the adhesion of the cutting fluid to the turntable 2. The turntable 2 is rotated by the turntable drive device 3, causing the cutting fluid in the machine tool water tank to continuously adhere to and be carried out by the turntable 2. The oil is then scraped off the turntable 2 by the oil scraping assembly 4 and enters the oil collection chamber 53 for recycling. The buffer chamber 52 is used to temporarily store the oil-water mixture. When the buffer chamber 52 collects a sufficient amount of the oil-water mixture, the mixture flows through the overflow inlet 501 into the turntable receiving chamber 51 and eventually into the machine tool water tank. The cutting fluid scraped off the turntable 2 by the oil scraping assembly 4 flows into the oil collection chamber 53.

[0035] The oil-water separator of this utility model is equipped with a liquid collection tank 5, which integrates the turntable holding chamber 51, the buffer chamber 52 and the oil collection chamber 53 into one place, making reasonable use of space, making the overall structure more compact, significantly reducing the overall footprint of the equipment and improving space utilization.

[0036] Specifically, the oil scraping assembly 4 includes a guide plate 41 and two oil scraping plates 42, and the oil collection chamber 53 has an avoidance notch on the side wall near the turntable receiving chamber 51 that is adapted to the shape of the guide plate 41.

[0037] The guide plate 41 includes an integrally formed horizontal portion 411 and an inclined portion 412. One end of the horizontal portion 411 in the X-axis direction is fixed to the side wall of the turntable accommodating chamber 51 near the turntable drive device 3, and the other end of the horizontal portion 411 in the X-axis direction is fixed to the top of the clearance notch. One end of the horizontal portion 411 in the Y-axis direction is fixed to the side wall of the turntable accommodating chamber 51 in the Y-axis direction. The other end of the horizontal portion 411 in the Y-axis direction is connected to the inclined portion 412. The end of the inclined portion 412 away from the horizontal portion 411 gradually tilts upward.

[0038] The inclined portion 412 is provided with a clearance opening 413, and the two oil scraping plates 42 are respectively disposed on one side of the clearance opening 413 in the X-axis direction. The oil scraping plate 42 includes an integrally formed fixing portion 421 and an oil scraping portion 422. The fixing portion 421 is fixed to the inclined portion 412, the lower end of the oil scraping portion 422 is connected to the fixing portion 421, and the upper end of the oil scraping portion 422 gradually tilts towards the turntable 2 and is close to the side of the turntable 2. The oil scraping portions 422 and the clearance opening 413 of the two oil scraping plates 42 cooperate to form a gap, and one side of the turntable 2 extends into the gap.

[0039] The turntable drive device 3 rotates, driving the turntable 2 to rotate. As the turntable 2 rotates, it carries out oil and a small amount of cutting fluid from the machine tool water tank. Since both sides of the turntable 2 are provided with oil scraper plates 42, and the oil scraping part 422 of the oil scraper plate 42 is close to the side of the turntable 2, the oil and cutting fluid are scraped off by the oil scraping part 422 when the turntable 2 rotates. The oil and cutting fluid pass through the inclined part 412 and the horizontal part 411 of the guide plate 41 in sequence and enter the oil collection chamber 53.

[0040] With the above structure, the oil scraping component 4 has a simple overall structure, can achieve high-efficiency oil-water separation, requires no maintenance during use, is safe and reliable, has a long service life and low operating cost.

[0041] Specifically, the material of the scraper blade 42 is rubber or hard plastic.

[0042] The oil scraper 42 is made of the above-mentioned material, which has a long service life and does not require frequent replacement. Moreover, it scrapes oil thoroughly, has low friction, and extends the service life of the turntable 2.

[0043] Specifically, the side wall of the oil collection chamber 53 is provided with an overflow outlet 502, and an oil outlet box 54 is provided on the outside of the overflow outlet 502, and the oil outlet box 54 is provided with an oil outlet 503.

[0044] After sufficient cutting oil is collected in the oil collection chamber 53, the cutting oil overflows from the overflow outlet 502 and enters the oil outlet box 54. Subsequently, the cutting oil is discharged through the oil outlet 503 of the oil outlet box 54. Workers can collect and recycle the cutting oil by placing a container below the oil outlet 503. This structure facilitates the collection and recycling of cutting oil by workers, reducing their workload.

[0045] Specifically, a baffle 55 is provided on the side of the turntable accommodating chamber 51 near the turntable drive device 3.

[0046] By adopting the above structure, the liquid in the machine tool water tank is prevented from splashing from the turntable housing 51 to the liquid collection tank 5 when the turntable 2 is rotating. This prevents the turntable drive device 3 or other components in the machine from being affected by water vapor and causing corrosion, thus extending the service life of the turntable drive device 3 and the whole machine.

[0047] Specifically, the output end of the turntable drive device 3 is provided with a fixing plate 31, and the turntable 2 is provided with a pressure plate 32 on the side facing away from the turntable drive device 3; the fixing plate 31 and the pressure plate 32 are detachably connected, and the turntable 2 is clamped by the fixing plate 31 and the pressure plate 32.

[0048] In one specific embodiment of this utility model, the turntable 2 is clamped between the fixing plate 31 and the pressure plate 32, and the pressure plate 32, the turntable 2, and the fixing plate 31 are fixedly connected by several screws. With this structure, the clamping action of the pressure plate 32 and the fixing plate 31 effectively stabilizes the turntable 2, preventing it from shaking or shifting during operation, reducing loosening or detachment caused by external forces, and improving the stability of the oil-water separator. Furthermore, the screw fixing method facilitates the installation and adjustment of the turntable, allowing for the replacement of a turntable 2 of a suitable size according to actual conditions.

[0049] Optionally, a protective cover 6 is also included, which is positioned above the liquid collection tank 5.

[0050] With the above structure, the protective cover 6 can prevent dust, debris, or liquid from entering the equipment, thereby avoiding dust, debris, or liquid contamination of the cutting fluid. In a specific embodiment of this utility model, a baffle 55 is provided on the side of the turntable receiving chamber 51 near the turntable drive device 3. When the protective cover 6 is placed above the liquid collection tank 5, the side wall of the protective cover 6 near the turntable drive device 3 is in close contact with the baffle 55.

[0051] Preferably, the top surface of the cover plate 1 is provided with a handle 11.

[0052] The above structure allows workers to lift or lower the cover plate 1 more easily, making it easier for them to open the cover plate 1 to clean the machine tool water tank, increasing the convenience of operation and reducing the labor intensity of manual labor.

[0053] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these equivalent modifications or substitutions are all included within the scope defined by the claims of this application.
