[0002] During the wastewater treatment process at the water center, when the wastewater flows from the previous water treatment process to the high-density sedimentation tank, the wastewater is mixed with oil due to production line reasons. At this time, due to the autonomous separation of oil and water, visible floating oil appears on the surface of the sedimentation tank water. The water collection tank is a device used to evenly collect the clear water overflowing from the sedimentation tank, and is mainly used at the outlet of the sedimentation tank.

[0003] If the floating oil is not cleaned, it will flow into the sump with the water flow, which will cause excessive burden on the downstream water treatment process, reduce the life of the ultrafiltration membrane and the reverse osmosis membrane, and reduce the water production rate of the ultrafiltration and reverse osmosis. Manual cleaning of floating oil is cumbersome and difficult to clean and collect floating oil on the water surface. In addition, the sedimentation tank is exposed to the outdoors, and floating objects such as leaves and plastic bags are often floating on the surface of the sedimentation tank. Manual cleaning of floating objects requires walking around the sedimentation tank, which is inconvenient and labor-intensive. Utility Model Content

Oil drain pipes 9 are connected to both ends of the oil collecting tank 4, and a lifting electric push rod 10 is installed on the top of the sliding seat 6. The output end of the lifting electric push rod 10 is connected to a transfer electric push rod 11, and the output end of the transfer electric push rod 11 is connected to a support frame 12. An air suction pump 13 is installed on the top of the support frame 12. The suction end of the air suction pump 13 is connected to one end of the top of the air suction pipe 14, and the other end of the bottom of the air suction pipe 14 is connected to an air suction box 15. An isolation orifice plate 16 is installed at the bottom of the air suction box 15, and a collecting box 25 is installed on both sides of one side of the sedimentation tank 1;

[0023] A pulling motor 18 is installed on both sides of both ends of the sedimentation tank 1, and the output end of the pulling motor 18 is connected to a winding roller 17, and a pull rope 19 is wound around the outside of the winding roller 17.

[0025] Working principle and usage process of the utility model: When installing the oil baffle 3, immerse the top of the oil sump 4 into the bottom of the water surface, so that the distance between the inner bottom surface of the oil sump 4 and the water surface is 15 cm. When the floating oil moves to the position of the oil baffle 3 along with the water flow, the floating oil enters the inside of the oil sump 4, and the floating floating oil flows into the inside of the drain pipe 9. Place a collection device at the other end of the drain pipe 9, and the floating oil is discharged from the inside of the drain pipe 9 into the collection device for subsequent treatment. When there are sundries floating on the surface of the sedimentation tank 1, the sundries will move to the top of the oil sump 4 along the water flow direction, and the oil baffle 3 blocks the sundries. At this time, pull the motor 18 to start, control the pull motor 18 to drive the winding roller 17 to rotate. Under the connection and driving action of the pull rope 19, the pull motor 18 drives the sliding seat 6 to move on the moving slide rail 5, thereby driving the suction box 15 to move. When the suction box 15 moves to the top of the floating object, the lifting electric push rod 10 drives the suction box 15 to descend, so that the isolation orifice plate 16 fits the floating object. At this time, the suction pump 13 starts. Under the connection effect of the suction pipe 14, the pressure inside the suction box 15 decreases, and the suction box 15 adsorbs the floating object. After adsorption, the lifting electric push rod 10 drives the floating object to rise, and the pull motor 18 drives the floating object to move to the position of the collection box 25. The transfer electric push rod 11 starts, and the output end of the transfer electric push rod 11 drives the suction box 15 to move to the top of the collection box 25. At this time, the suction pump 13 pauses running, and the floating object falls into the inside of the collection box 25, completing the cleaning and collection of the sundries, without the need for manual walking around the sedimentation tank 1 to clean the floating objects on the water surface of the sedimentation tank 1, reducing the labor intensity of manual work;

[0026] When the floating oil inside the oil sump 4 solidifies, the heating wire 21, the swinging motor 23 and the external air delivery pump operate. The external air delivery pump delivers air into the spray pipe 20. The air is heated by the heating wire 21 and then sprayed out through the spray holes 22. At the same time, the swinging motor 23 drives the spray pipe 20 to swing, so that the spray holes 22 face the oil sump 4. Under the heating action of the hot air, the solidified floating oil melts, and the melted floating oil is discharged through the drain pipe 9. When the water temperature is too low, it can prevent the floating oil from sticking to the surfaces of the oil baffle 3 and the oil sump 4, ensuring the normal cleaning and collection of the floating oil. When the temperature is low, it can also ensure the normal operation of the equipment, with a wide range of applications.
