DETAILED DESCRIPTION

[0020] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0021] The intelligent start-stop floating oil collector according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0022] like Figure 1-2 As shown, the embodiment of the present invention proposes an intelligent start-stop floating oil collector, comprising: an oil collecting tank 7, a float 8 and a filter 6, the oil collecting tank 7 has an upper opening, an oil content monitoring device 9 and an oil discharge pump 10 are arranged at the bottom of the oil collecting tank 7, the oil discharge pump 10 is connected to an oil discharge hose 3 to discharge the floating oil in the oil collecting tank 7 to the outside of the sewage well, the oil discharge hose 3 is connected to a check valve, an oil film thickness monitoring device 5 is arranged at the upper end of the oil collecting tank 7 to monitor the thickness of the floating oil film in the sewage well, and the oil content monitoring device 5 is arranged at the upper end of the oil collecting tank 7 to monitor the thickness of the floating oil film in the sewage well. The measuring device 9, the oil discharge pump 10 and the oil film thickness monitoring device 5 are electrically connected to the intelligent electric control box 1 respectively. After receiving the monitoring signals of the oil content monitoring device 9 and the oil film thickness monitoring device 5, the intelligent electric control box 1 controls the start and stop of the oil discharge pump 10; the float 8 is connected to the outside of the oil collecting tank 7, and the float 8 provides buoyancy for the oil collecting tank 7 so that the upper end surface of the oil collecting tank 7 is located below the liquid level of the sewage well; the filter screen 6 is detachably connected to the upper end of the oil collecting tank 7 to prevent solid impurities in the well from entering the oil collecting tank 7.

[0023] The embodiment of the present invention can realize the functions of automatic monitoring of leaking floating oil and intelligent control of the start and stop of the oil discharge pump 10 by adopting the oil film thickness monitoring device 5, the oil content monitoring device 9, the oil discharge pump 10 and the intelligent electric control box 1, without the need for manual observation and cleaning of floating oil in the well, eliminating the safety risks brought by manual cleaning of floating oil, improving the efficiency of floating oil cleaning, having the function of preliminary separation of oil and water, reducing the amount of oily wastewater to be treated, and without the need to consume oil cleaning consumables, thus avoiding secondary pollution and waste of resources. It also reduces the risk range of accidents of oil-using equipment. The oil content of the water discharged from the oil-collecting wastewater well after the floating oil is collected by the equipment meets the national standard GB8978 emission standard of 5 mg / L on land, inland rivers and offshore.

[0024] The embodiment of the present invention can ensure that the oil collecting tank 7 will not sink in the sewage well by setting an external buoy 8, and keep the upper edge of the oil collecting tank 7 always submerged at an appropriate height below the liquid level of the sewage well, so as to ensure that the floating oil in the sewage well flows normally into the oil collecting tank 7. By setting the filter 6, it is ensured that the floating oil flows normally into the oil collecting tank 7, and at the same time, it is effectively prevented that floating debris enters the oil collecting tank 7 and causes the oil discharge pump 10 to be blocked. By connecting a check valve to the oil discharge hose 3, the discharged dirty oil can be prevented from flowing back.

[0025] When in use, the oil film thickness monitoring device 5 monitors the thickness of the floating oil film in the sewage well in real time. When a certain thickness of floating oil is detected in the well, the detection signal is fed back to the intelligent electric control box 1, and the intelligent electric control box 1 automatically issues an order to start the oil discharge pump 10 to pump oil. The oil floating on the water surface enters the oil collecting tank 7 through the filter screen 6 at the upper edge of the oil collecting tank 7, and the floating oil is pumped out of the well by the oil discharge pump 10. When the oil content monitoring device 9 in the oil collecting tank 7 detects that the oil content in the oil collecting tank 7 is lower than the set value, the monitoring signal is fed back to the intelligent electric control box 1, and the intelligent electric control box 1 automatically issues an order to stop the oil discharge pump 10 from pumping oil, thereby realizing the function of intelligent control of floating oil collection.

[0026] The intelligent start-stop floating oil collector of the embodiment of the present invention has the characteristics of high working efficiency, compact structure, reliable use, convenient operation, etc., and is widely applicable to the collection and treatment of floating oil in various still water areas.

[0027] Furthermore, the oil discharge hose 3 is led to the oil storage tank outside the sewage well.

[0028] Furthermore, the detachable connection mode of the filter screen 6 may be a bolt connection.

[0029] In some embodiments, the intelligent start-stop floating oil collector further includes a bracket 13, which is detachably connected to the wall of the sewage well, and the oil collecting tank 7 is slidably connected to the bracket 13 through the slide bar 11, so that the oil collecting tank 7 floats only in the vertical direction. By providing the bracket 13 as a follower device of the oil collecting tank 7, the range of movement of the oil collecting tank 7 can be controlled to ensure that the vertical position of the oil collecting tank 7 can slide up and down as the liquid level changes.

[0030] Furthermore, the top of the bracket 13 is detachably connected to the wall of the sewage well, and the detachable connection method can be bolt connection or other detachable connection methods.

[0031] In some embodiments, the slide rod 11 is arranged in the horizontal direction, one end of the slide rod 11 is fixedly connected to the bottom of the oil collecting tank 7, and the other end of the slide rod 11 is fixedly connected to the slider mechanism 12. A vertical slide 131 is provided on the bracket 13, and the slider mechanism 12 is slidably connected to the slide 131.

[0032] Furthermore, a connecting rod is fixedly connected to the bottom center of the oil collecting tank 7, the connecting rod is vertically arranged, and the connecting rod is detachably fixed to the end of the connecting slide rod 11, and the detachable connection method can be a bolt connection.

[0033] In some embodiments, Figure 2 As shown, the slider mechanism 12 includes a shell 122, a slider 123 and a roller 121. The slider 123 is fixedly connected to the left and right sides of the shell 122. The slideways 131 are symmetrically arranged on the left and right sides of the bracket 13. The slider 123 and the slideway 131 are slidably matched. The rollers 121 are arranged in two rows and are symmetrically distributed on the left and right sides of the shell 122. The rollers 121 are rotatably connected to the shell 122 through a rotating shaft. The two rows of rollers 121 are respectively rollingly matched with the slideways 131 on both sides of the bracket 13, and the multiple rollers 121 in each row are symmetrically arranged on the upper and lower sides of the slider 123.

[0034] By arranging the roller 121 on the slider mechanism 12, a combination of sliding fit and rolling fit is achieved, so that the lifting and lowering of the oil collecting tank 7 is smoother.

[0035] In some embodiments, a lifting point is provided on the oil collecting tank 7, and the lifting point is connected to a rope for lifting the oil collecting tank 7. By setting the lifting point, the lifting of the oil collecting tank 7 is facilitated.

[0036] Furthermore, the hanging point may be arranged at the bottom of the oil collecting tank 7 , may be arranged at the upper edge of the oil collecting tank 7 , or may be arranged on the outer side wall of the oil collecting tank 7 .

[0037] In some embodiments, the upper part of the bracket 13 is connected to the automatic retracting and releasing mechanism 4, and the rope, the oil discharge hose 3, and the wires of the oil content monitoring device 9, the oil discharge pump 10, and the oil film thickness monitoring device 5 are all connected to the automatic retracting and releasing mechanism 4. The rope, the oil discharge hose 3, and the wires and cables can be retracted and released in real time as the oil collecting tank 7 is raised or lowered.

[0038] Furthermore, the automatic retractable mechanism 4 includes a plurality of pulleys for winding and retracting the rope, the oil drain hose 3 and the electric wire respectively.

[0039] In some embodiments, the filter screen 6 is a vertical filter screen 6, which is arranged around the upper edge of the oil collecting tank 7, and the upper end surface of the filter screen 6 is located above the liquid level of the sewage well, so as to ensure that the floating oil in the well flows into the oil collecting tank 7 normally, and effectively prevent floating debris from entering the oil collecting tank 7 and causing the oil discharge pump 10 to be blocked.

[0040] In some embodiments, the intelligent start-stop floating oil collector further includes an oil-water separator 2, which is connected to an oil discharge hose 3 located outside the well to separate the oil discharged from the oil collecting tank 7 from oil and water, and the oil discharge port of the oil-water separator 2 is connected to the oil storage tank, and the water discharge port of the oil-water separator 2 is connected to the water storage tank. Since the extracted oil is a mixture of oil and water, the oil and water can be further separated and stored separately for recycling, or the water can be discharged into the well again.

[0041] Furthermore, a liquid level gauge is provided in the oil-water separator 2, and the liquid level gauge is connected to the intelligent electric control box 1. When the liquid level in the oil-water separator 2 reaches a set height, the intelligent electric control box 1 automatically issues an order to turn off the oil drain pump 10, and when the liquid level in the oil-water separator 2 is below the set height again, the intelligent electric control box 1 automatically issues an order to turn on the oil drain pump 10 to continue to feed oil into the oil-water separator 2.

[0042] In some embodiments, the water outlet of the water storage tank is connected to a circulation pipeline, and the water outlet end of the circulation pipeline leads to a sewage well.

[0043] In some embodiments, the buoy 8 is a cylindrical tubular structure with a hollow sealed cavity inside the buoy 8 , and the buoy 8 is sleeved on the outside of the oil collecting tank 7 .

[0044] It should be noted that the hollow and sealed cavity of the float 8 provides buoyancy for the float 8, and the volume design of the float 8 takes into account factors such as the weight and volume of the oil collecting tank 7, the material of the float 8, and the buoyancy of the oil-water mixture in the well, so that the oil collecting tank 7 is just suspended below the liquid level of the sewage well.
