Description

Technical Field

[0001] The utility model relates to an oil interceptor, in particular to an oil interceptor with stirring type oil-water separation. Background Technique

[0002] In the prior art, an oil interceptor with stirring type oil-water separation is a device that separates oil and water in an oil-water mixture through stirring. Such an oil interceptor usually includes a stirrer, which can fully mix the oil and water in the oil-water mixture, so as to separate the oil from the water. Subsequently, the oil and water are separated in different areas of the oil interceptor respectively. The oil can be discharged through the upper oil outlet, while the water can be discharged through the bottom water outlet. The oil interceptor with stirring type oil-water separation can usually effectively separate oil and water and improve the oil-water separation efficiency. At the same time, due to the action of the stirrer, the oil-water mixture in the oil interceptor can be evenly mixed, thus reducing the time and energy consumption in the oil-water separation process.

[0003] After retrieval, a patent with the Chinese patent application number 201621350639.3 discloses an oil interceptor with impurity filtration and oil-water separation, including an oil interceptor body, an anti-seepage layer, a first sedimentation area, a primary filter plate, a second sedimentation area, a fine filter plate, a fine filtration plate, an oil collection device, a silt cleaning port, an inlet, a stepped diversion area, a stepped filter plate, a drain port, an overflow weir, a partition board, a floating net, an oil outlet, a third sedimentation area, a limiting block. The stepped diversion area is arranged on the side of the oil interceptor body, the stepped filter plate is arranged in the stepped diversion area, and at the same time, one end of the stepped diversion area is provided with an inlet, and the other end is connected to the first sedimentation area; the limiting block is arranged under the stepped filter plate; the second sedimentation area is arranged next to the first sedimentation area; the overflow weir is arranged next to the second sedimentation area; the third sedimentation area is arranged next to the overflow weir. The following deficiencies exist in the oil interceptor with impurity filtration and oil-water separation in the above patent:

[0004] Although the impurities in the oil are separated from the oil by using the principle of different oil and water densities in combination with the sedimentation method, and then the oil is filtered out by using the phenomenon that the density of water is greater than that of oil and the oil floats on the water to achieve the first step of waste oil regeneration, the purpose of removing water and impurities, but after filtering the sediment, the time for the oil and water to separate statically by themselves is too long, and stirring is needed to accelerate the oil-water separation speed. Content of the Utility Model

[0005] The purpose of the utility model is to solve the deficiencies existing in the prior art, and to provide an oil interceptor with stirring type oil-water separation.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] An oil separation tank for stirred oil-water separation, comprising an isolation tank body, one side of the isolation tank body is fixedly connected with a starting motor, the circumferential surface of the starting motor is fixedly connected with an L-shaped fixing rod, and the output end of the starting motor is fixedly connected with a stirrer. A mixing tank is arranged inside the isolation tank body, an oil-water mixing tank is arranged inside the isolation tank body, and a water tank is arranged inside the isolation tank body. One end of the isolation tank body is fixedly connected with a liquid inlet pipe, and a first valve is arranged on the circumferential surface of the liquid inlet pipe. An inclined baffle is fixedly connected inside the mixing tank.

[0008] As a further scheme of the present invention: a slag discharge pipe is fixedly connected to the top of the isolation tank body, a drain pipe is fixedly connected to the bottom of the isolation tank body, a second valve is arranged on the circumferential surface of the slag discharge pipe, and a third valve is arranged on the circumferential surface of the drain pipe.

[0009] As a further scheme of the present invention: a first isolation screen is arranged between the mixing tank and the oil-water mixing tank, a hydrophilic and oleophobic filter screen is arranged between the oil-water mixing tank and the water tank, and inclined plates are fixedly connected to the bottoms of the oil-water mixing tank and the water tank.

[0010] As a further scheme of the present invention: a threaded rod is movably connected to the top of the isolation tank body, and a turning knob is fixedly connected to the top of the threaded rod.

[0011] As a further scheme of the present invention: a fixed column is fixedly connected to the top of the isolation tank body, and an oil extraction pipe is movably connected inside the fixed column.

[0012] As a further scheme of the present invention: a cross bar is movably connected to the circumferential surface of the threaded rod, and the oil extraction pipe is fixedly connected to the cross bar.

[0013] As a further scheme of the present invention: a filter element is fixedly connected to the inner circumferential surface of the oil extraction pipe, and a cavity is fixedly connected to one end of the oil extraction pipe.

[0014] Compared with the prior art, the present invention provides an oil separation tank for stirred oil-water separation, which has the following beneficial effects:

[0015] 1. The oil interceptor for a stirred oil-water separation allows an oil-water mixed solution to enter the interior of the mixing tank through the liquid inlet pipe. By rotating the first valve, the flow rate of the oil-water mixed solution entering the mixing tank can be controlled. And through the inclined baffle, the liquid flow rate and impact force can be slowed down, so that the oil-water mixed solution can only slowly flow through the holes to the right side inside the mixing tank, thereby preventing the static liquid inside the isolation tank body from being agitated. At the same time, by starting the motor, the stirrer can be driven to rotate to stir the oil-water mixed solution, and the oil and water molecules can be better mixed together to form an emulsion. The emulsified mixture will form tiny oil-water particles, increasing the oil-water interface, thus accelerating the oil-water separation speed. Therefore, the problem that a large amount of oil remains on the filter screen during the filtration of the sediment and the oil needs to be fully mixed with water through stirring to reduce the oil residue is solved.

[0016] 2. The oil interceptor for a stirred oil-water separation isolates the sediment inside the mixing tank through the first isolation screen. The oil and water flow into the interior of the oil-water mixing tank. Since the density of the oil is greater than that of water, the water flows into the interior of the water tank through the hydrophilic and oleophobic filter screen, and the oil is isolated inside the oil-water mixing tank. The inclined plate can prevent the water flowing into the water tank from flowing back into the oil-water mixing tank through the hydrophilic and oleophobic filter screen again, which affects the extraction of the oil. The sediment can be discharged through the slag discharge pipe, and the slag discharge pipe can be closed to discharge the sediment by rotating the second valve, preventing the oil and water from being discharged from the isolation tank body through the slag discharge pipe. At the same time, the water inside the water tank can be discharged through the drain pipe, and the drain of the water tank can be closed through the third valve. Therefore, the problem of discharging the sediment and water is solved.

[0017] 3. The oil interceptor for a stirred oil-water separation drives the threaded rod to rotate synchronously by rotating the knob, so that the cross bar and the oil extraction pipe move up or down. When the oil extraction pipe moves downward, the oil to be extracted submerges the top of the cavity, filling the cavity with oil, making the energy consumed in the oil extraction process less. At the same time, the oil to be extracted is filtered again through the filter element to prevent the sediment in the oil in the oil-water mixing tank from being extracted by the oil pump, solving the problem of discharging the separated oil in the oil-water mixing tank.

[0018] The parts not involved in this device are the same as or can be implemented by the prior art. The structure of the present utility model is simple and the operation is convenient. Description of the Drawings

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0026] An oil interceptor with a stirring type oil-water separation, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5As shown in the figure, it includes an isolation pool body 1. One side of the isolation pool body 1 is fixedly connected with a starting motor 2. The circumferential surface of the starting motor 2 is fixedly connected with an L-shaped fixing rod 3, and the output end of the starting motor 2 is fixedly connected with a stirrer 10. Inside the isolation pool body 1, there is a mixing tank 20, an oil-water mixing tank 21, and a water tank 22. One end of the isolation pool body 1 is fixedly connected with a liquid inlet pipe 5. A first valve 4 is arranged on the circumferential surface of the liquid inlet pipe 5. Inside the mixing tank 20, there is an inclined baffle 11. Users can make the oil-water mixed solution enter the inside of the mixing tank 20 through the liquid inlet pipe 5. By rotating the first valve 4, the flow rate of the oil-water mixed solution entering the mixing tank 20 can be controlled. And through the inclined baffle 11, the liquid flow rate and impact force can be slowed down, so that the oil-water mixed solution can only slowly flow to the right inside the mixing tank 20 through the holes, thereby preventing the stirred liquid in the isolation pool body 1 from being disturbed. At the same time, by starting the motor 2, the stirrer 10 can be driven to rotate to stir the oil-water mixed solution, so that the oil and water molecules can be better mixed together to form an emulsion. The emulsified mixture will form tiny oil-water particles, increasing the oil-water interface, thereby accelerating the oil-water separation speed. Thus, the problem that a large amount of oil remains on the filter screen during the filtration of the precipitate and the oil needs to be stirred to fully mix with the water to reduce the oil residue is solved.

[0027] As Figure 2 , Figure 3 shown, a slag discharge pipe 6 is fixedly connected to the top of the isolation pool body 1, and a drain pipe 8 is fixedly connected to the bottom of the isolation pool body 1. A second valve 7 is arranged on the circumferential surface of the slag discharge pipe 6, and a third valve 9 is arranged on the circumferential surface of the drain pipe 8. A first isolation screen 23 is arranged between the mixing tank 20 and the oil-water mixing tank 21, and a hydrophilic oleophobic filter screen 24 is arranged between the oil-water mixing tank 21 and the water tank 22. And inclined plates 19 are fixedly connected to the bottoms of the oil-water mixing tank 21 and the water tank 22. Since the density of the precipitate is greater than that of the oil and water, the precipitate is isolated inside the mixing tank 20 through the first isolation screen 23, and the oil and water flow into the inside of the oil-water mixing tank 21. And the density of the oil is greater than that of the water. Through the hydrophilic oleophobic filter screen 24, the water flows into the inside of the water tank 22, and the oil is isolated inside the oil-water mixing tank 21. Through the inclined plates 19, it can be prevented that the water flowing into the inside of the water tank 22 flows back into the oil-water mixing tank 21 through the hydrophilic oleophobic filter screen 24 again, affecting the extraction of the oil. The precipitate can be discharged through the slag discharge pipe 6, and by rotating the second valve 7, the slag discharge pipe 6 can be closed to discharge the precipitate, preventing the oil and water from being discharged from the isolation pool body 1 through the slag discharge pipe 6. At the same time, the water inside the water tank 22 can be discharged through the drain pipe 8, and by the third valve 9, the discharge of water from the water tank 22 can be closed. Thus, the problem of discharging the precipitate and water is solved.

[0028] As Figure 3 , Figure 4 ,Figure 5 As shown in the figure, a threaded rod 17 is movably connected to the top of the isolation tank body 1. A rotary knob 16 is fixedly connected to the top of the threaded rod 17. A fixed column 13 is fixedly connected to the top of the isolation tank body 1. An oil suction pipe 14 is movably connected inside the fixed column 13. A cross bar 15 is movably connected to the circumferential surface of the threaded rod 17. The oil suction pipe 14 is fixedly connected to the cross bar 15. A filter element 18 is fixedly connected to the inner circumferential surface of the oil suction pipe 14. One end of the oil suction pipe 14 is fixedly connected to a cavity 12. The user rotates the rotary knob 16 to drive the threaded rod 17 to rotate synchronously, so that the cross bar 15 and the oil suction pipe 14 move up or down. When the oil suction pipe 14 moves downwards, the oil to be extracted submerges the top of the cavity 12, filling the cavity 12 with oil, making the energy consumed in the oil extraction process less. At the same time, the filter element 18 filters the oil to be extracted again, preventing the oil in the oil-water mixing tank 21 with sediment from being extracted by the oil pump, and solving the problem of discharging the oil separated in the oil-water mixing tank 21.

[0029] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
