[0036] See also Figures 1 to 11 The present invention provides a technical solution: an oil-water separation device with a self-cleaning function, comprising a main body 1, wherein a first collecting tank 3 and a second collecting tank 31 are respectively arranged on both sides of the main body 1, wherein the first collecting tank 3 collects the separated coolant, and the second collecting tank 31 collects the oil;

[0038] An oil-water separation plate 4, wherein the oil-water separation plate 4 is arranged above the first collecting tank 3, and the oil-water separation plate 4 separates and filters the oil mixed in the coolant;

[0039] Through the structure of the oil-water separation plate 4, the oil and dirt mixed into the coolant are filtered and blocked, so that the coolant can continue to move downward through the oil-water separation plate 4, and the oil and dirt cannot pass through the oil-water separation plate 4, thereby achieving the effect of oil-water separation.

[0040] A lifting frame 5, wherein the lifting frame 5 is arranged below the oil-water separation plate 4, and a scraper 6 is arranged above the outer side of the lifting frame 5, and the scraper 6 scrapes off the oil stains adhered to the inner wall of the first collecting tank 3;

[0041] By raising the lifting frame 5 and under the structural action of the scraper 6, the oil stains adhering to the inner wall above the first collecting tank 3 are scraped off to prevent the oil stains from accumulating on the inner wall above the first collecting tank 3 for a long time and hindering the normal up and down sliding of the oil-water separation plate 4 after solidification.

[0042] An oil scraper 72 is slidably connected above the oil-water separation plate 4 , and the oil scraper 72 assists the oil-water separation plate 4 in introducing oil into the second collecting tank 31 , thereby accelerating the oil collection rate.

[0043] Through the structure of the scraper plate 72, while assisting the rapid transportation of oil and dirt on the surface of the oil-water separation plate 4, the oil and dirt on the upper surface of the oil-water separation plate 4 are scraped off to prevent the oil and dirt from accumulating on the surface of the oil-water separation plate 4 and causing blockage, so that the coolant cannot flow downward through the oil-water separation plate 4.

[0044] A switch door 11 is provided on the front side of the main body 1, and the switch door 11 is used to install and remove the first collection tank 3 and the second collection tank 31. A support frame is provided on the inner wall of the main body 1 above the first collection tank 3, and a bracket 21 is supported and connected above the support frame. A filter screen 2 is provided on the inner side of the bracket 21, and the filter screen 2 filters metal debris mixed in the coolant and oil. The main body 1 is located above the second collection tank 31 for sealing.

[0045] By opening the switch door 11, the first collecting tank 3 and the second collecting tank 31 can be conveniently pulled out from the main body 1. Through the structure of the support frame and the bracket 21, the installation and disassembly of the filter screen 2 is convenient, so that the metal debris filtered on the surface of the filter screen 2 can be cleaned in time to avoid clogging the mesh of the filter screen 2.

[0046] The first collecting tank 3 and the second collecting tank 31 are arranged side by side in the main body 1, and a circulation pipe 32 is provided on the adjacent side of the first collecting tank 3 and the second collecting tank 31, and the circulation pipe 32 extends into the second collecting tank 31. The bottom of the first collecting tank 3 is provided with an opening, and the part of the main body 1 located below the opening of the first collecting tank 3 is provided with a discharge pipe 33, and the discharge pipe 33 is connected to the opening of the first collecting tank 3, and an opening and closing component is provided on the discharge pipe 33.

[0047] Through the structure of the circulation pipe 32, the oil filtered in the first collecting tank 3 is introduced into the second collecting tank 31, and through the structure of the discharge pipe 33, the coolant after filtration in the first collecting tank 3 is discharged to the outside, so that the coolant can be quickly put into use after the oil and water are separated.

[0048] An oil-water separation plate 4 is slidably connected to the upper part of the first collecting tank 3, and a first sealing gasket 41 is provided on the side walls of the oil-water separation plate 4. The oil-water separation plate 4 slides in a sealed manner with the inner wall of the first collecting tank 3 through the first sealing gasket 41. A symmetrically distributed first column 42 is provided below the side of the oil-water separation plate 4 away from the second collecting tank 31, and a symmetrically distributed second column 43 is provided below the side of the oil-water separation plate 4 close to the second collecting tank 31. The first column 42 and the second column 43 are fixedly connected to the inner wall of the bottom of the first collecting tank 3, and the height of the first column 42 is greater than that of the second column 43.

[0049] Through the structure of the first sealing gasket 41, the upper and lower spaces of the oil-water separation plate 4 in the first collecting tank 3 are separated, so that the coolant can only flow downward through the oil-water separation plate 4, so that the oil-water separation plate 4 can separate and filter the oil mixed in the coolant, and the filtered oil will not be mixed into the coolant again through the side gaps of the oil-water separation plate 4.

[0050] The first column 42 and the second column 43 are both configured as cavity structures, and a lifting column 45 is vertically slidably connected in the cavity of the first column 42 and the second column 43, and a sealing ring 44 is provided on the top inner wall of both. The first column 42 and the second column 43 are sealed and slid with the lifting column 45 through the sealing ring 44, and a first spring 46 is provided below the lifting column 45, one end of the first spring 46 is fixedly connected to the bottom of the lifting column 45, and the other end of the first spring 46 is fixedly connected to the bottom inner wall of the first column 42 and the second column 43, and a first rotating wheel 47 is fixedly connected to the top of the lifting column 45, and the first rotating wheel 47 is hinged to a connecting frame 48, and the connecting frame 48 is installed below the oil-water separation plate 4.

[0051] The lifting column 45 slides in the first column 42 and the second column 43, so that the oil-water separation plate 4 can slide up and down in the first collecting tank 3, and because the height of the first column 42 is greater than the height of the second column 43, the accumulation of oil on the surface of the oil-water separation plate 4 makes its overall mass greater than the elastic force of the first spring 46, that is, the oil-water separation plate 4 slides downward, so that in the process of the lifting column 45 sliding downward in the two, the first rotating wheel 47 will first abut against the upper end of the first column 42, and the first rotating wheel 47 is rotatably connected to the oil-water separation plate 4 through the connecting frame 48, so that the oil-water separation plate 4 flips toward the direction of the second column 43, so that the oil accumulated on the surface of the oil-water separation plate 4 flows into the circulation pipe 32 and is introduced into the second collecting tank 31. After the introduction is completed, under the elastic force of the first spring 46, the oil-water separation plate 4 slides upward to reset to the horizontal level.

[0052] The first column 42 and the second column 43 respectively penetrate the lifting frame 5 and are slidably connected with the lifting frame 5. A second sealing gasket 51 is provided on the side wall of the lifting frame 5. The lifting frame 5 slides in a sealed manner with the inner wall of the first collecting tank 3 through the second sealing gasket 51. A float 52 is installed under the lifting frame 5. When coolant accumulates at the bottom of the first collecting tank 3, the lifting frame 5 is controlled to slide upward. A filter plate 53 is installed on the inner side of the lifting frame 5. The filter plate 53 performs secondary filtration on the coolant flowing downward, so that the oil mixed in the coolant is intercepted on the surface of the filter plate 53. A baffle plate 54 is fixedly installed at the lower side of the lifting frame 5 facing the flow pipe 32.

[0053] When the equipment needs to be cleaned, a cleaning liquid is injected into the first collecting tank 3, and the discharge pipe 33 is closed, so that the cleaning liquid accumulates in the first collecting tank 3. Under the buoyancy of the float 52, the lifting frame 5 slides vertically upward, and the oil-water separation plate 4 does not hinder the circulation of the cleaning liquid, so the cleaning liquid does not accumulate on the surface of the oil-water separation plate 4, that is, during the cleaning process, the oil-water separation plate 4 does not drop. After the lifting frame 5 rises to the highest point, the baffle 54 abuts against the circulation pipe 32, so that the circulation pipe 32 is closed to prevent the cleaning liquid from flowing out of the first collecting tank 3;

[0054] During the oil-water separation process, the filter plate 53 in the lifting frame 5 performs secondary oil filtering on the coolant flowing downward, thereby improving the filtering effect.

[0055] The scraper 6 is slidably connected to the upper outer side of the lifting frame 5, and a plurality of thrust blocks 61 are fixedly connected to the lifting frame 5. The push rod 62 is horizontally slidably connected inside the thrust block 61, and the end of the push rod 62 is fixedly connected to the inner side of the scraper 6. A plurality of spline grooves are provided on the outer wall of the push rod 62, and symmetrically distributed splines 63 are fixedly connected to the inner wall of the thrust block 61. The splines 63 are slidably connected to the spline grooves. A second spring 64 is provided on the side of the push rod 62 facing the thrust block 61, and the two ends of the second spring 64 are respectively fixedly connected to the push rod 62 and the inner wall of the thrust block 61. A connecting rope 65 is also fixedly connected to the end of the push rod 62, and the connecting rope 65 passes through the thrust block 61 and is fixedly connected to the lower side of the oil-water separation plate 4.

[0056] When the upper and lower heights of the oil-water separation plate 4 remain unchanged, the rise of the lifting frame 5 causes the connecting rope 65 to gradually loosen, so that the scraper 6 pops outward under the elastic force of the second spring 64. After the scraper 6 rises to the flow height of the oil in the first collecting tank 3, the scraper 6 clings to the inner wall of the first collecting tank 3, scrapes off the oil adhering to the inner wall of the first collecting tank 3, and makes it fall onto the filter plate 53. The stubborn oil is dissolved with the flushing of the cleaning liquid, and the discharge pipe 33 is opened to discharge the cleaning liquid and the dissolved oil.

[0057] The main body 1 is located above the first collecting tank 3 and is fixedly connected to the inner walls on both sides thereof, guide rails 12 are respectively connected thereto for horizontal sliding movement, a slide 7 is connected thereto for horizontal sliding movement, a slide plate 71 is fixedly installed between the slide plates 7 on both sides, an elastic component is arranged between the slide plate 71 and the inner wall on the left side of the main body 1, an oil scraper plate 72 is connected thereto for sliding movement below the slide plate 71, the lower part of the oil scraper plate 72 abuts against the upper surface of the oil-water separation plate 4, a plurality of movable grooves are arranged above the oil scraper plate 72, a fixed column 73 is connected thereto for vertical sliding movement in the movable groove, the upper part of the fixed column 73 is fixedly connected to the lower part of the slide plate 71, a third spring 74 is arranged below the fixed column 73, one end of the third spring 74 is fixedly connected to the lower part of the fixed column 73, and the other end of the third spring 74 is fixedly connected to the inner wall of the movable groove.

[0058] The part of the oil-water separation plate 4 located above the second column 43 is hinged with a second rotating wheel 81, and a rack 8 is fixedly connected above the second rotating wheel 81. A limiting assembly for the rack 8 is provided on the inner wall of the main body 1, and the rack 8 is vertically slidably connected to the main body 1. A gear 91 is provided on one side of the rack 8, and the gear 91 meshes with the rack 8 for transmission. The gear 91 is installed on the outer side of the winding wheel 9, and the gear 91 rotates coaxially with the winding wheel 9. One side of the winding wheel 9 is rotatably connected to the inner wall of the main body 1 through an axis. A pull rope 92 is coiled on the winding wheel 9, and the other end of the pull rope 92 is fixedly connected to the skateboard 71.

[0059] The gear 8 is engaged with the gear 91 and the gear 8 is engaged with the gear 92, so that the gear 8 slides downward, driving the wire reel 9 to flip over, so that the pull rope 92 is wound around the wire reel 9, and the other end of the pull rope 92 pulls the slide plate 71 to move in the direction of the oil-water separation plate 4, so that the slide table 7 slides horizontally along the guide rail 12. Under the elastic force of the third spring 74, the oil scraper plate 72 pops up vertically downward and adheres to the upper surface of the oil-water separation plate 4 even if the oil-water separation plate 4 is flipped, the oil scraper plate 72 can still adhere to the upper surface of the oil-water separation plate 4, assisting the transportation of oil and dirt on the surface of the oil-water separation plate 4 while scraping off the accumulated and solidified oil and dirt on the surface of the oil-water separation plate 4 to avoid blockage caused by a large amount of accumulated solidified oil and dirt. After the oil and dirt on the surface of the oil-water separation plate 4 are introduced, the oil-water separation plate 4 is reset upward, and under the action of the elastic component, the slide plate 71 slides in the opposite direction until it is reset.
