Description

[Technical Field]

[0001] This utility model relates to the field of floating oil and scum extraction, specifically a self-adjusting floating oil suction device. [Background Technology]

[0002] Currently, most restaurants that repeatedly discharge wastewater into collection tanks during kitchen use employ direct submersible pumps for treatment. Alternatively, some establishments use automatic extraction to remove floating oil and scum from the surface of the wastewater when the liquid level reaches a fixed interface.

[0003] However, the former cannot handle the floating oil and scum on the surface of the collection tank at all, while the latter uses a fixed interface for automatic extraction, which is an instantaneous process. Because the process is instantaneous, this mode can only partially handle the floating oil and scum on the surface of the collection tank and cannot effectively handle them automatically. As a result, the floating oil and scum on the surface cannot be automatically and effectively handled, leading to the formation of clumps, crusts, and garbage accumulation on the upper layer of the collection tank. This crusting and garbage accumulation not only prevents the water level control elements in the collection tank from functioning properly, but also causes long-term garbage accumulation, resulting in foul odors and other environmental pollution problems. [Utility Model Content]

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a self-adjusting floating oil suction device that can freely float up and down with the liquid surface of the collection tank to absorb floating oil and scum, thereby maximizing the automatic treatment of floating oil and scum on the surface of the collection tank.

[0005] To achieve the above objectives, a self-adjusting floating oil suction device is designed, including a water collection tank 12. A water collection tank inlet pipe 13 is connected to the water collection tank 12 and is located at the upper part of the water collection tank 12. Oily wastewater from kitchen catering is discharged into the water collection tank 12 through the water collection tank inlet pipe 13. A floating oil suction float 1 is provided in the water collection tank 12. The floating oil suction float 1 is connected to a fixed flow guide channel 7, which is located at the bottom of the water collection tank 12. The floating oil suction float 1 floats up and down between the upper baffle 4 and the lower baffle 6 of the float through its fixed float limiting plate 5, and floats up and down with the rise and fall of the liquid level. The other end of the fixed flow guide channel 7 is connected to a conveying pipe 11 through a floating oil suction actuator 9. The floating oil suction actuator 9 and the conveying pipe 11 are connected through a floating oil suction coupler 10.

[0006] Furthermore, the fixed flow channel 7 is fastened to the oil suction actuator 9 by fastening screws 8, and the other end of the conveying pipe 11 is connected to the oil-water separator. The oil suction actuator 9 conveys the oil, scum and oily wastewater to the oil-water separator for treatment through the floating oil suction coupler 10 and the conveying pipe 11.

[0007] Furthermore, the floating oil-absorbing float 1 has a docking hole at its center, and the fixed flow channel 7 extends into the docking hole of the floating oil-absorbing float 1. The floating oil-absorbing float 1 floats up and down around the fixed flow channel 7 through the docking hole as the liquid level of the water collection tank 12 rises and falls.

[0008] Furthermore, the fixed flow channel 7 is fixedly connected with an upper float baffle 4 and a lower float baffle 6 arranged vertically. The bottom end of the floating oil suction float 1 is fixed with a float limiting plate 5. The float limiting plate 5 is located between the upper float baffle 4 and the lower float baffle 6. The floating oil suction float 1 is limited vertically by the float limiting plate 5.

[0009] Furthermore, the float limiting plate 5 is an annular plate, the inner diameter of the float limiting plate 5 is larger than the outer diameter of the fixed flow channel 7, and the inner diameter of the float limiting plate 5 is smaller than the outer diameter of the upper float baffle 4 and the lower float baffle 6, thereby ensuring the reliability of the limiting.

[0010] Furthermore, a floating guide plate 3 is fixedly connected to the top of the fixed flow channel 7. The outer diameter of the floating guide plate 3 is smaller than the inner diameter of the docking hole of the floating oil suction float 1. Under the guidance of the floating guide plate 3, the floating oil suction float 1 maintains stability in the up-and-down floating direction.

[0011] Furthermore, the floating oil-absorbing float 1 is provided with an auxiliary oil-absorbing hole 2 on its side, and auxiliary oil is absorbed through the auxiliary oil-absorbing hole 2.

[0012] Compared with existing technologies, this invention adopts a mode that allows it to float freely up and down with the liquid level in the collection tank to absorb floating oil and scum, thereby maximizing the automatic absorption of floating oil and scum from the surface of the collection tank. Furthermore, because the device operates by automatically floating up and down with the liquid level in the collection tank, the absorption of floating oil and scum is a sustained process over a relatively long period, rather than a momentary action at a specific interface. Therefore, this mode maximizes the automatic treatment of floating oil and scum from the surface of the collection tank, maintaining a relatively clean liquid level and ensuring the normal sensing function of the liquid level control element in the collection tank for a longer period. It also prevents the accumulation of waste and the generation of foul odors, thus protecting the surrounding environment. [Image Description]

The water collection tank inlet pipe 13 is located at the upper part of the water collection tank 12. Oily wastewater from kitchen and catering is discharged into the water collection tank 12 through the water collection tank inlet pipe 13. A floating oil suction float 1 is provided in the water collection tank 12, and the floating oil suction float 1 is connected to a fixed guide channel 7. The fixed guide channel 7 is located at the bottom of the water collection tank 12. The floating oil suction float 1 floats through its fixed buoyancy. The sub-limiting plate 5 floats up and down between the upper baffle 4 and the lower baffle 6 of the float as the liquid level rises and falls. The other end of the fixed guide channel 7 is connected to the conveying pipe 11 through the oil suction actuator 9. The oil suction actuator 9 and the conveying pipe 11 are connected through the floating oil suction coupler 10. The fixed guide channel 7 and the oil suction actuator 9 are fastened together by the fastening screws 8. The other end of the conveying pipe 11 is connected to the oil-water separator. The oil suction actuator 9 conveys the floating oil, scum and oily wastewater to the oil-water separator for treatment through the floating oil suction coupler 10 and the conveying pipe 11.

[0018] The floating oil-absorbing float 1 has an auxiliary oil-absorbing hole 2 on its side, and auxiliary oil is absorbed through the auxiliary oil-absorbing hole 2; the floating oil-absorbing float 1 has a docking hole arranged vertically at its center, and the fixed flow channel 7 extends into the docking hole of the floating oil-absorbing float 1. The floating oil-absorbing float 1 floats up and down around the fixed flow channel 7 through the docking hole as the liquid level of the water collection tank 12 rises and falls. The fixed flow channel 7 is fixedly connected with an upper float baffle 4 and a lower float baffle 6 arranged vertically. The bottom of the floating oil suction float 1 is fixed with a float limiting plate 5, which is located between the upper float baffle 4 and the lower float baffle 6. The floating oil suction float 1 is limited vertically by the float limiting plate 5. The float limiting plate 5 is an annular plate. The inner diameter of the float limiting plate 5 is larger than the outer diameter of the fixed flow channel 7, and the inner diameter of the float limiting plate 5 is smaller than the outer diameter of the upper float baffle 4 and the lower float baffle 6, thereby ensuring the reliability of the limiting. The top of the fixed flow channel 7 is fixedly connected with a floating guide plate 3. The outer diameter of the floating guide plate 3 is smaller than the inner diameter of the docking hole of the floating oil suction float 1. The floating oil suction float 1 maintains the stability of the vertical floating direction under the guidance of the floating guide plate 3.

[0019] The working principle of this utility model is as follows: Oily wastewater from the kitchen is discharged into the collection tank 12 through the inlet pipe 13. The inlet pipe 13 is connected to the collection tank 12 and is located at the upper part of the collection tank 12. The floating oil-absorbing float 1 is connected to the fixed guide channel 7. The floating oil-absorbing float 1 floats up and down between the upper baffle 4 and the lower baffle 6 of the float through its fixed float limiting plate 5, and automatically absorbs floating oil and scum as the liquid level rises and falls. Its operation process is to absorb floating oil and scum within a relatively high and low liquid level range for a relatively long time, which can maximize the automatic treatment of floating oil and scum on the surface of the collection tank. The floating oil-absorbing float 1 maintains reliable and stable upward and downward floating direction under the guidance of the floating guide plate 3. The fixed flow channel 7 is fastened to the oil suction actuator 9 by fastening screws 8. The oil suction actuator 9 is connected to the conveying pipeline 11 by the floating oil suction coupler 10. The oil suction actuator 9 automatically conveys the oil, scum and oily wastewater to the target oil-water separator for automatic treatment through the floating oil suction coupler 10 and the conveying pipeline 11.

[0020] This invention automatically removes floating oil and scum from the surface of a water collection tank over a relatively long period of time within a large liquid level difference range. Because it operates automatically over a considerable period, this invention effectively removes floating oil and scum from the surface of the water collection tank, while also maintaining a relatively clean liquid level. This ensures the normal operation of the liquid level control components within the tank for an extended period and prevents the accumulation of waste that could produce foul odors, thus protecting the surrounding environment.
