[0002] With the increasing number of restaurants in cities, the amount of wastewater discharged from restaurants is also increasing. Restaurant wastewater contains a large amount of animal and vegetable oils. After these oils enter the city's drainage pipes, they will adhere to and accumulate on the inner wall of the pipes. Over time, the oil layer will thicken, causing the inner diameter of the pipes to decrease or even block the pipes. This will not only cause sewage to overflow and affect environmental sanitation, but also increase the maintenance cost of the city's drainage system.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Example 1: Reference Figures 1-5An intelligent oil-water separation tank includes a tank body 1 and further includes: a liquid-turning unit, wherein the liquid-turning unit includes a liquid-turning component and a filter section, the filter section dividing the liquid-turning unit into a first separation chamber and a second separation chamber, the mixture of water, oil and solid waste passes through the first separation chamber and the second separation chamber and then passes over the liquid-turning component to form a primary separation, namely solid-liquid separation of the mixture; an oil separation unit and a water separation unit, wherein the tank body 1 is provided with a third separation chamber, the oil separation unit and the water separation unit are both located in the third separation chamber, the oil outlet of the oil separation unit is located at the top of the third separation chamber, the water inlet of the water separation unit is located at the bottom of the third separation chamber, the mixture of water and oil enters the third separation chamber and forms a secondary separation, namely water-oil separation; the liquid-turning unit, the oil separation unit and the water separation unit are arranged sequentially in the tank body 1 along the flow direction of the mixture.

[0022] Reference Figures 3-5 The liquid-turning assembly includes a ramp plate 2, which is fixed to the inner wall of the tank body 1, and forms a preset angle with the horizontal plane, preferably 15 degrees. One end of the ramp plate 2 extends and is fixed to the bottom of the vertical section side wall of the tank body 1, and the other end of the ramp plate 2 is fixedly connected to a slag discharge filter plate 21. Multiple sets of slag discharge holes 211 are equally spaced inside the slag discharge filter plate 21, and a liquid-turning plate 22 is fixedly connected to the side wall of the slag discharge filter plate 21. The filtration part includes a mounting frame 3, which is fixedly connected to the top of the inner wall of the inlet end of the tank body 1. Multiple sets of slag discharge holes 211 are opened on the vertical section side wall of the mounting frame 3. The filter holes 31 are arranged in a group, and the filter holes 31 located at the bottom of the vertical section side wall are flush with the top of the liquid-turning plate 22. The horizontal section of the mounting frame 3 has an open slot, and a filter element 33 is inserted into the open slot. The filter element 33 can be a filter basket. The filter basket is inserted into the open slot to filter solid waste in the mixed liquid. At the same time, it is convenient to remove the filter basket to empty the waste, which improves the convenience of use. A water inlet pipe 32 is fixed and connected to the outer wall of the inlet end of the pool body 1. The output end of the water inlet pipe 32 is located above the filter element 33, and the input end of the water inlet pipe 32 is connected to the sewage pipe of the kitchen.

[0023] With the above structure, kitchen wastewater first enters the filter element 33 in the first separation chamber along the inlet pipe 32. After solid-liquid separation, the liquid part passes through the filter element 33 and enters the second separation chamber. As the liquid increases, the liquid level in the second separation chamber eventually exceeds the tipping plate 22, and finally the water-oil mixture enters the third separation chamber for water and oil separation.

[0024] The flow rate of the slag discharge hole 211 is much smaller than that of the water inlet pipe 32, ensuring that the flow path of the water-oil mixture always passes over the liquid-turning plate 22 before entering the third separation chamber. The slag discharge hole 211 is designed to discharge the fine sediment particles that fall onto the inclined plate 2 after passing through the filter element 33 into the third separation chamber, thus preventing the fine sediment particles from accumulating on the inclined plate 2. The inclined plate 2 is designed to guide the fine sediment particles to the slag discharge hole 211 for discharge.

[0025] Reference Figures 3-5 The oil separation unit includes at least two sets of oil guide plates 4. The oil guide plates 4 are fixed to the top of the third separation chamber, and the oil guide plates 4 form a preset angle with the horizontal plane, preferably 15 degrees. An oil separation box 41 is fixedly connected to the inclined top of the oil guide plate 4, and an oil outlet pipe 42 is fixedly connected to the bottom of the oil separation box 41. An oil guide hopper 43 is fixedly connected to the outer wall of the oil outlet pipe 42, and the bottom end of the oil outlet pipe 42 is connected to the top of the inner cavity of the third separation chamber. The top of the liquid-turning plate 22 is higher than the bottom end of the oil outlet pipe 42. A limiting frame 44 connected to the third separation chamber is fixedly connected to the bottom of the oil guide plate 4 directly below the oil outlet pipe 42. An opening and closing ball 45 is placed inside the limiting frame 44. The density of the opening and closing ball 45 is between that of oil and water. The material of the opening and closing ball 45 is made by mixing polymer microspheres into resin, and the overall density is precisely controlled to be between 0.96 and 0.99 g / cm³. 3 This is to ensure that the opening and closing ball 45 can float on the water surface and sink to the bottom of the oil, and that the outer diameter of the opening and closing ball 45 is larger than the inner diameter of the bottom end of the oil outlet pipe 42.

[0026] With the above structure, after the water-oil mixture enters the third separation chamber, the oil will float on the water surface. As the liquid level in the third separation chamber increases, the oil will move along the oil guide plate 4 to the bottom of the oil outlet pipe 42. At this time, because the density of the opening and closing ball 45 is between the oil and water, the oil will directly pass over the opening and closing ball 45 and enter the oil outlet pipe 42. Finally, under the buoyancy generated by the continuous rise of the liquid level, it will be discharged along the oil outlet pipe 42 and the oil guide hopper 43. After the oil in the third separation chamber is discharged, under the buoyancy of the water, the opening and closing ball 45 will float up and block the bottom of the oil outlet pipe 42.

[0027] In addition, a shielding box 46 is fixedly connected to the side wall of the oil distribution box 41. A transparent observation window is provided on the top of the shielding box 46. The output end of the oil guide bucket 43 extends into the shielding box 46. An oil receiving box 47 is inserted into the bottom of the shielding box 46. The oil receiving box 47 is located directly below the output end of the oil guide bucket 43. The shielding box 46 can effectively prevent oil splashing along the oil guide bucket 43, ensuring the cleanliness of the working area.

[0028] Reference Figure 3 , Figure 4In addition, a controller 5 is fixedly connected to the top of the oil guide plate 4, and an electric push rod 6 is fixedly connected to the inner wall of the oil separator 41. The electric push rod 6 is electrically connected to the controller 5, and the telescopic end of the electric push rod 6 is located directly above the oil outlet pipe 42. In this way, during the water-oil separation process, the telescopic movement of the electric push rod 6 can be controlled to interfere with the sinking of the opening and closing ball 45, so as to avoid the situation where the opening and closing ball 45 is stuck to the bottom of the oil outlet pipe 42 due to the viscosity of the oil and cannot fall down by itself, thus ensuring that the separated oil can be discharged smoothly.

[0029] Reference Figure 2 , Figure 5 In addition, a heater 9 is fixedly connected to the outer wall of the pool 1. The output end of the heater 9 extends through the water-turning plate 71 and into the third separation chamber. By using the heater 9, the mixture in the third separation chamber can be heated to prevent the oil from condensing at low temperature and causing poor flow, thus ensuring the water and oil separation effect.

[0030] Reference Figure 4 , Figure 5 The water distribution unit includes a water distribution box 7, which is fixedly connected to the inclined top of the oil guide plate 4. A water-turning plate 71 is fixedly connected to the inner wall of the third separation chamber. The side wall of the oil guide plate 4 is attached to the side wall of the water-turning plate 71. The water inlet of the water-turning plate 71 is located at the bottom of the third separation chamber. The top of the water-turning plate 71 extends into the water distribution box 7. A drain pipe 72 is fixed and connected to the side wall of the water distribution box 7, and the inclined bottom end of the oil guide plate 4 faces the input end of the drain pipe 72.

[0031] With the above structure, when the opening and closing ball 45 floats up and blocks the bottom of the oil outlet pipe 42, the water in the third separation chamber will flow along the water-turning plate 71 into the water distribution box 7. As the liquid increases, it will pass over the water-turning plate 71 and enter the water distribution box 7, eventually flowing out through the drain pipe 72. Then, when oil is re-entered into the third separation chamber, the oil will float on the water surface, causing the opening and closing ball 45 to sink into the oil, thereby releasing the blockage of the oil outlet pipe 42 and allowing the oil to continue to be discharged. This achieves effective separation of solids, oil, and water, effectively improving the separation effect.

[0032] Among them, the top of the liquid-turning plate 22 is higher than the top of the water-turning plate 71. According to the principle of communicating vessels, when the water-oil mixture can pass over the liquid-turning plate 22 and enter the third separation chamber, there will definitely be separated water discharged at the drain pipe 72.

[0033] Reference Figures 2-4A flushing pipe 8 and a slag discharge pipe 81 are fixedly connected to the outer wall of the pool body 1. The slag discharge pipe 81 is connected to the bottom of the inner cavity of the third separation chamber. A slag guide plate 82 is provided at the bottom of the third separation chamber. The inclined bottom end of the slag guide plate 82 faces the input end of the slag discharge pipe 81. A backflushing pipe 83 is fixedly connected to the bottom of the inner cavity of the third separation chamber. The input end of the backflushing pipe 83 is connected to the flushing pipe 8. Multiple sets of flushing holes are opened on the side wall of the backflushing pipe 83.

[0034] With the above structure, the slag discharge pipe 81 is opened periodically to discharge the water-oil mixture remaining in the third separation chamber and the fine particulate impurities that enter through the slag discharge hole 211. Water is then introduced into the backflushing pipe 83 through the flushing pipe 8 and discharged through the flushing hole. In this way, the water flow force is used to flush the bottom of the entire tank 1, thereby effectively cleaning the tank 1 and ensuring that it can maintain a good water and oil separation effect in the future.

[0035] Example 2: Reference Figures 1-5 Based on Example 1, an intelligent oil-water separation system is proposed, comprising the following steps: Step 1: After the mixture enters the first separation chamber, solid-liquid separation is performed by the filtration section; Step 2: Water and oil will continuously enter the second separation chamber. During the liquid descent, water and oil will briefly mix together. As the liquid increases, water will eventually carry oil across the liquid-turning assembly and enter the third separation chamber, moving to the oil separation unit and water separation unit. Step 3: The oil outlet of the oil separator is opened automatically by buoyancy, so that the oil is discharged along the oil separator and the water is discharged along the water separator. Step 4: Use the force of water flow to periodically clean the remaining oil and sludge in the third separation chamber.

[0036] Example 3: Reference Figure 6To facilitate the cleaning of pool 1, an automatic cleaning system is proposed. This system includes a power supply module, a timer switch, a PLC control module, an inlet solenoid valve, a drain solenoid valve, and a heating switch. The timer switch, PLC control module, inlet solenoid valve, drain solenoid valve, and heating switch are electrically connected, and the PLC control module is electrically connected to the power supply module. The inlet solenoid valve is located in the flushing pipe 8, and the drain solenoid valve is located in the slag discharge pipe 81. The heating switch controls the opening and closing of the heater 9, the timer switch controls the opening and closing of the PLC control module, and the power supply module provides power to the aforementioned electronic equipment. The timer switch controls the PLC control module to turn on periodically, and then the PLC control module issues cleaning commands to the inlet solenoid valve, drain solenoid valve, and heating switch, thereby achieving effective cleaning of pool 1 and ensuring that pool 1 maintains good separation performance during long-term use.

[0037] In this invention, during use, kitchen wastewater first enters the filter element 33 in the first separation chamber along the inlet pipe 32. After solid-liquid separation, the liquid portion passes through the filter element 33 and enters the second separation chamber. As the liquid level increases, the liquid level in the second separation chamber eventually surpasses the tipping plate 22. At this point, the water-oil mixture enters the third separation chamber. Since oil has a lower density than water, the oil floats on the water surface after entering the third separation chamber. As the liquid level in the third separation chamber increases, the oil moves along the oil guide plate 4 towards the bottom of the oil outlet pipe 42. At this point, because the density of the opening and closing ball 45 is between the oil and water, the oil directly passes over the opening and closing ball 45. The oil enters the oil outlet pipe 42 and is eventually discharged through the oil outlet pipe 42 and the oil guide hopper 43 under the buoyancy generated by the continuous rise of the liquid level. After the oil in the third separation chamber is discharged, the opening and closing ball 45 will float up and block the bottom of the oil outlet pipe 42 under the buoyancy of the water. At this time, the water in the third separation chamber will flow into the water distribution box 7 along the water-turning plate 71. After the liquid increases, it will pass over the water-turning plate 71 and enter the water distribution box 7, and finally flow out through the drain pipe 72. Then, when the oil is re-entered into the third separation chamber, the opening and closing ball 45 will sink into the oil because the oil floats on the water surface, thereby releasing the blockage of the oil outlet pipe 42 and allowing the oil to continue to be discharged, thus achieving effective separation of solids, oil and water.
