DETAILED DESCRIPTION

[0024] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention. Example

[0025] like Figures 1 to 5 As shown, an oil-water separation device for collecting floating oil in a waste oil pool in an embodiment of the first aspect of the present invention includes a first shell 1, which has multiple first shells 1, and the multiple first shells 1 enclose a closed area. A support frame 4 is arranged at the center of the area enclosed by the multiple first shells 1. The support frame 4 can rotate, and an outlet 5 and a toggle member are provided on the support frame 4. The oil-water mixture enters the first shell 1 through the outlet 5. The first shell 1 has a cavity opening upward, and the lower end face of the cavity has an inclined bottom surface, and a water outlet 2 is provided at the center of the bottom surface. A valve assembly 3 is provided in the water outlet 2, and when the support frame 4 rotates, the valve assembly 3 can rotate accordingly to open / close the water outlet 2. A limiting assembly and a suction assembly are also provided in the first shell 1, and the suction assembly is sleeved outside the limiting assembly, and the limiting assembly can limit the downward movement distance of the suction assembly.

[0026] When the device is in use, the oil-water mixture in the first shell 1 can be extracted by the suction component to extract the oil in the upper layer, and the use of the limit component can prevent the suction component from extracting the water in the lower layer (or reduce the amount of water extracted), thereby making it easier for users to use the device.

[0027] When the device is in use, the outlet 5 can pour the oil-water mixture into the first shell 1. The first shell 1 has multiple parts and is surrounded by a circle on the support frame 4, so that the device can be used without stopping. That is, after the outlet 5 has filled the first first shell 1 with liquid, the outlet 5 rotates and then fills the next first shell 1 with liquid. At this time, the liquid in the first first shell 1 is left to stand, so that the oil floats on the water surface. After standing for a predetermined time, the suction component can suck the oil to separate the oil and water.

[0028] The upper end of the support frame 4 is fixedly connected to a cross frame 15, and a channel is provided in the cross frame 15. One end of the channel is connected to the oil-water mixture, and the other end is connected to the outlet 5. A second shell 10 is provided outside the first shell 1, and a fixing seat 11 is provided above the cross frame 15. The fixing seat 11 is fixedly connected to the second shell 10. The oil-water mixture can be pumped into the channel by a water pump and then enter the first shell 1 through the outlet 5.

[0029] A first drive motor 12 is fixedly connected to one side of the fixed seat 11, and the first drive motor 12 has an output shaft 16. A second rotating shaft 19 is fixedly connected to the cross frame 15. Pulleys 17 are fixedly connected to the outside of the output shaft 16 and the second rotating shaft 19, and a belt 18 is wound around the outside of the pulley 17, so that when the first drive motor 12 rotates, the support frame 4 rotates accordingly. By using the first drive motor 12, the support frame 4 can be rotated, and then the position of the outlet 5 can be controlled, so that the oil-water mixture enters different first shells 1.

[0030] The valve assembly 3 includes a valve plate 8, to which a first rotating shaft 9 is fixedly connected. A through hole is also provided on the valve plate 8, and when the through hole is opposite to the water outlet 2, the liquid in the first shell 1 can flow through the valve plate 8. A gear is provided on the first rotating shaft 9, and the toggle member includes a fixed rod 13 and a tooth block 14. One end of the fixed rod 13 is fixed to the support frame 4, and the other end thereof is connected to the tooth block 14. The tooth block 14 and the gear cooperate with each other so that when the fixed rod 13 rotates with the support frame 4, the tooth block 14 can toggle the gear.

[0031] The fixing rod 13 and the cross frame 15 are located in the same vertical plane.

[0032] When the outlet 5 is located above a first shell 1, the gear block 14 can move the first rotating shaft 9 in the first shell 1, so that the valve plate 8 closes the water outlet 2. When the outlet 5 rotates to the top of the next first shell 1, the gear block 14 can continue to move the first rotating shaft 9, and when the outlet 5 rotates to the top of the first shell 1 next time, the suction assembly can suck the oil therein, and the water therein can flow out through the outlet 5.

[0033] The limiting assembly includes a second drive motor 20, a lead screw 21 and a sliding rod 22. The second drive motor 20 is installed at the upper end of the first shell 1. The output end of the second drive motor 20 is fixedly connected to the lead screw 21. The sliding rod 22 is sleeved outside the lead screw 21, and the sliding rod 22 and the lead screw 21 are threaded together. The end of the sliding rod 22 can be pressed against the inner wall of the first shell 1 to prevent the sliding rod 22 from rotating. An image acquisition module 23 is provided on the first shell 1. The image acquisition module 23 can capture images of the liquid in the vertical direction, and the output end of the image acquisition module 23 is connected to the analysis module. The analysis module is used to determine the position of the water-oil contact surface, and the output end of the analysis module is connected to the input end of the control module. The output end of the control module is connected to the second drive motor 20, and when the upper end surface of the sliding rod 22 coincides with the oil-liquid contact surface, the second drive motor 20 can stop rotating.

[0034] The suction assembly comprises a floating plate 6 capable of floating on the liquid surface and an oil pipe 7, one end of the oil pipe 7 penetrating through the floating plate 6 and slightly extending below the floating plate 6, and a water pump connected to the other end of the oil pipe 7 to suck the oil on the liquid surface.

[0035] The surface of the first shell 1 is provided with a transparent plate arranged vertically, and the image acquisition module 23 can acquire the image of the first shell 1 through the transparent plate, so as to install the image acquisition module 23.

[0036] The floating plate 6 is made of foam material and is provided with a perforation for accommodating the oil pipe 7. Since the floating plate 6 needs to float on the liquid surface and the oil pipe 7 moves up and down with the floating plate 6, a part of the oil pipe 7 needs to be arranged on the floating plate 6, so that the floating plate 6 needs to provide sufficient buoyancy.

[0037] The upper surface of the connection part of two adjacent first shells 1 is an upwardly curved arc surface, so as to avoid the accumulation of oil-water mixture on the upper surface of the first shell 1.
