Description

Technical Field

[0001] The present invention relates to the technical field of floating oil recovery, and specifically to a floating oil recovery device for oil tanks and oil ponds. Background Art

[0002] During the long-term use of oil storage facilities such as oil tanks and oil ponds, a floating oil layer often forms on the liquid surface. These floating oils may come from the condensation residues after the evaporation of oil products, the floating of light components during the oil-water separation process, or the lubricating oil mixed in during equipment operation. The accumulation of floating oil not only affects the quality of oil products but also may cause waste of resources, so it needs to be effectively recovered.

[0003] The floating oil pumping device is a floating oil recovery device widely used in oil storage facilities such as oil tanks and oil ponds. Its core principle is to use a floating body structure to keep the oil pumping port always in the floating oil layer on the liquid surface, and realize the directional recovery of floating oil through pump suction or siphon action.

[0004] In the floating oil recovery operation of oil storage facilities such as oil tanks and oil ponds, the traditional fixed-buoyancy floating body structure faces significant adaptability challenges. Due to the significantly different physical properties of different oil products - light crude oil (density about 0.75 - 0.85 g / cm 3 ), lubricating oil (0.86 - 0.94 g / cm 3 ), and waste oil (0.88 - 0.96 g / cm 3 ) and other media have a large density change range, and at the same time, there are significant differences in viscosity characteristics (which can differ by hundreds of centistokes from low-viscosity kerosene to high-viscosity waste oil) and liquid level fluctuation amplitudes (which can reach dozens of centimeters due to temperature changes and feeding and discharging operations). Such complex working conditions make it difficult for the floating body with a fixed-buoyancy design to maintain the best working state. Specifically, when dealing with low-density oil products, the fixed-buoyancy floating body may immerse too deep, resulting in the oil pumping port sucking in the lower water phase; while in high-density oil products, it may float too high, causing insufficient suction of the floating oil layer; in addition, under dynamic liquid level conditions, the fixed-buoyancy structure cannot adjust the draft depth in real time, further exacerbating the risk of oil-water mixing. These limitations ultimately lead to problems such as a decrease in floating oil recovery efficiency, insufficient purity of oil products, and poor system stability, especially when dealing with complex waste oil or oil-water mixed media.

[0005] Therefore, we have developed a new floating oil recovery device for oil tanks and oil ponds. Summary of the Invention

[0006] (I) Technical Problems to be Solved

[0007] In view of the deficiencies of the prior art, the present invention provides a floating oil recovery device for oil tanks and oil ponds, which solves the problem that the existing floating oil recovery device has insufficient adaptability, resulting in the inability of the oil pumping port to accurately follow the floating oil layer and affecting the recovery efficiency.

[0008] (2) Technical Solution

[0009] To achieve the above objectives, the present invention is implemented through the following technical solutions: An oil slick recovery device for an oil tank oil sump, comprising a housing and a controller. On one side of the outer surface of the housing, a positioning bracket is fixedly installed. On the top of the positioning bracket, a floating ball bracket is positioned and placed. At the center of the floating ball bracket, a funnel is fixedly connected. On one side of the outer surface of the floating ball bracket, a vibration type density sensor is fixedly installed;

[0010] A pumping component is jointly installed between the funnel and the housing;

[0011] On the inner bottom of the housing, three gas regulation components are fixedly installed. An electric lifting component is jointly installed among the three gas regulation components;

[0012] On the outer surfaces of the three gas regulation components, connecting pipes are fixedly installed. At the top of the connecting pipes, rotary joints are fixedly penetrated. At the movable ends of the three rotary joints, hollow winding wheels are fixedly penetrated. At the winding ends of the three hollow winding wheels, rubber hoses are fixedly penetrated. And the rubber hoses penetrate through the housing and are connected to the floating ball bracket;

[0013] An elastic reset component is jointly installed between each of the three hollow winding wheels and the housing.

[0014] Preferably, the positioning bracket includes a placement rack, and the placement rack is fixedly installed on the outer wall of one side of the housing. At the top of the placement rack, three positioning rings are fixedly embedded.

[0015] Through the above technical solutions, the placement rack of the positioning bracket is rigidly connected to the housing, ensuring the stability of the overall structure. The three positioning rings are symmetrically distributed, enabling the positioning blocks of the floating ball body to be accurately inserted, ensuring the horizontal attitude of the floating ball bracket.

[0016] Preferably, the floating ball bracket includes three floating ball bodies. At the bottom of each of the three floating ball bodies, a positioning block is fixedly connected, and the positioning block is matched with the positioning ring. At the top of each of the three floating ball bodies, a fixed pipe is fixedly penetrated, and the fixed pipe is fixedly penetrated with the adjacent rubber hose. On the outer surfaces of the three floating ball bodies, mounting frames are fixedly sleeved. And the vibration type density sensor is fixedly installed on the outer wall of one side of the mounting frame. And the funnel is fixedly installed at the center of the mounting frame. And the fixed pipe is fixedly installed on the top of the mounting frame.

[0017] Through the above technical solution, the three floating ball bodies form a stable triangular support structure, improving the anti-overturning ability of the floating ball bracket and ensuring balance can still be maintained during oil fluid fluctuations. The fixed pipe is connected through and through with the rubber pipe, enabling the gas regulation component to precisely control the buoyancy of the floating ball. The vibration type density sensor is directly installed on the floating ball bracket, which can monitor the change of the oil layer density in real time, ensuring that the oil pumping port is always located at the optimal position of the floating oil layer.

[0018] Preferably, the oil pumping component includes an oil pump, and the oil pump is fixedly installed on the top of the housing. The output end of the oil pump is fixedly penetrated with a drain pipe, and the input end of the oil pump is fixedly penetrated with an inlet pipe. The other end of the inlet pipe is fixedly penetrated with a hose, and the hose is fixedly installed at the bottom of the funnel and communicated with the funnel.

[0019] Through the above technical solution, the oil pump is directly connected to the funnel through the hose, forming an efficient oil pumping channel, ensuring that the floating oil can be pumped quickly and continuously. The hose is made of oil-resistant and corrosion-resistant materials to adapt to the recovery requirements of different oil products. The drain pipe can be flexibly connected to external oil storage equipment to achieve centralized recovery or treatment of the floating oil, improving the operation efficiency.

[0020] Preferably, each of the three gas regulation components includes a base, and the base is fixedly installed on the inner bottom of the housing and fixedly connected to the connecting pipe. The top of the base is fixedly connected with a cylinder body. A piston is hermetically slid on the inner surface of the cylinder body. The top of the piston is fixedly connected with a movable rod. A flow channel penetrating through to the side wall is opened at the top of the base, and both ends of the flow channel are communicated with the cylinder body and the connecting pipe respectively.

[0021] Through the above technical solution, the piston of the gas regulation component hermetically slides in the cylinder body and is communicated with the connecting pipe through the flow channel, forming a closed gas circulation system. When the piston moves up and down, the gas amount in the floating ball can be precisely adjusted, thereby dynamically controlling the buoyancy and keeping the funnel always at the optimal depth of the oil layer.

[0022] Preferably, the electric lifting component includes a motor, and the motor is fixedly installed on the inner top of the housing. The driving end of the motor is fixedly connected with a screw rod. An activity plate is threadedly sleeved on the outer surface of the screw rod, and the activity plate is fixedly connected between the three movable rods.

[0023] Through the above technical solution, the motor drives the screw rod to rotate, driving the activity plate to move up and down, thereby synchronously controlling the movement of the pistons of the three gas regulation components. This linkage design ensures that the buoyancy adjustment of the three floating balls is consistent, avoiding the funnel tilting due to uneven buoyancy and affecting the oil pumping effect. At the same time, the screw rod transmission structure has a self-locking function, which can remain stable after adjustment and reduce energy consumption.

[0024] Preferably, all three of the elastic reset components include support shafts, and the support shafts are fixedly connected to the adjacent hollow winding wheels. A support seat is rotatably sleeved on the outer surface of the support shaft, and the support seat is fixedly installed on the inner wall of one side of the housing. A scroll spring sleeved on the outer surface of the support shaft is arranged inside the support seat, and both ends of the scroll spring are fixedly connected to the support shaft and the support seat respectively.

[0025] Through the above technical solution, the scroll spring of the elastic reset component stores energy when the hollow winding wheel rotates. After the floating ball finishes moving, the spring force drives the winding wheel to reverse, so that the rubber hose automatically rewinds, avoiding winding or loosening of the rubber hose. This design not only extends the service life of the rubber hose, but also reduces manual intervention and improves the automation degree of the equipment.

[0026] Preferably, a heat dissipation hole is formed in one side of the outer surface of the housing.

[0027] Through the above technical solution, the heat dissipation hole effectively promotes the air circulation inside and outside the housing, preventing electronic components such as motors from overheating due to long-term operation.

[0028] Preferably, four traveling wheels are symmetrically and fixedly installed at the bottom of the housing, and a handrail is fixedly installed on one side of the outer surface of the housing.

[0029] Through the above technical solution, the four traveling wheels enable the device to move flexibly, adapting to the operation requirements of different oil tanks or oil pools. The handrail design facilitates the operator to push, pull and position, improving the portability and working efficiency of the equipment, especially suitable for floating oil recovery operations in large industrial sites.

[0030] Preferably, the controller is fixedly installed on the top of the housing.

[0031] Through the above technical solution, the controller centrally manages the operation of the oil pump, the motor and the sensor, and automatically adjusts the buoyancy and the oil pumping rate through real-time data analysis, realizing intelligent control. Its installation position on the top is convenient for the operator to observe and debug.

[0032] (III) Beneficial effects

[0033] The present invention provides an oil tank and oil pool floating oil recovery device. It has the following beneficial effects:

[0034] 1. The floating oil recovery device for the oil tank oil pool realizes intelligent detection and adaptive adjustment of the oil layer thickness through the combined structure of the floating ball bracket and the vibration type density sensor. Specifically, the vibration type density sensor can monitor the density change of the oil-water interface in real time and feed the data back to the controller. The controller precisely controls the buoyancy adjustment of the floating ball bracket by analyzing the data to ensure that the oil pumping port of the funnel always maintains the optimal working depth (such as 1 cm below the oil layer). This design effectively solves the problem of low oil pumping efficiency caused by oil layer fluctuations in traditional floating oil recovery devices, and at the same time avoids pumping lower layer water or impurities.

[0035] 2. The floating oil recovery device for the oil tank oil pool adopts the cooperative working mechanism of the gas regulation component and the elastic reset component, significantly improving the stability and service life of the device. The three gas regulation components are linked and controlled by the electric lifting component, which can synchronously adjust the buoyancy of the floating ball to avoid the device tilt caused by uneven buoyancy; while the elastic reset component can automatically wind and unwind the rubber hose when the floating ball moves, preventing the pipeline from being entangled or overstretched. This design not only enables the device to adapt to the working environments of different oil pools, but also reduces the frequency of manual intervention. Brief Description of the Drawings

[0044] As Figures 1-6 shown, the present invention provides an oil slick recovery device for an oil tank oil sump, which includes a housing 1 and a controller 11. A heat dissipation hole 3 is provided on one side of the outer surface of the housing 1.

The positioning bracket includes a placement rack 2, and the placement rack 2 is fixedly installed on the outer wall of one side of the housing 1. Three positioning rings 17 are fixedly embedded at the top of the placement rack 2. The floating ball bracket includes three floating ball bodies 4. The bottoms of the three floating ball bodies 4 are fixedly connected with positioning blocks 16, and the positioning blocks 16 are matched with the positioning rings 17. Fixed pipes 13 are fixedly penetrated through the tops of the three floating ball bodies 4. Mounting frames 12 are fixedly sleeved on the outer surfaces of the three floating ball bodies 4. The vibrating density sensor 14 is fixedly installed on the outer wall of one side of the mounting frame 12. The funnel 15 is fixedly installed at the center of the mounting frame 12. The fixed pipes 13 are fixedly installed on the top of the mounting frame 12. It can detect the oil layer density in real time and feed the data back to the controller 11 to ensure that the oil pumping port is always located at the optimal oil layer position (such as 1 cm below the water surface), avoiding the oil slick recovery effect.

[0046] The vibrating density sensor 14 is selected from the Anton Scientific AK-DM300 series, which has the following characteristics in this application: direct contact measurement, real-time feedback of oil layer density changes; 316L stainless steel material, resistant to oil corrosion; calibratable, adaptable to different oil product characteristics.

[0047] An oil pumping assembly is jointly installed between the funnel 15 and the housing 1. The oil pumping assembly includes an oil pump 10, and the oil pump 10 is fixedly installed on the top of the housing 1. The output end of the oil pump 10 is fixedly penetrated by an oil discharge pipe 9, and the input end of the oil pump 10 is fixedly penetrated by an oil inlet pipe 8. The other end of the oil inlet pipe 8 is fixedly penetrated by a flexible pipe 7, and the flexible pipe 7 is fixedly installed at the bottom of the funnel 15 and communicates with the funnel 15. The oil pumping assembly includes the oil pump 10, the oil inlet pipe 8, the flexible pipe 7, and the oil discharge pipe 9.

[0048] The oil pump 10 is fixed on the top of the housing 1 and communicates with the funnel 15 through the flexible pipe 7 to form an oil pumping channel. When the oil pump 10 is started, the surface floating oil is sucked in through the funnel 15 and then discharged through the oil discharge pipe 9 to the floating oil recovery and treatment equipment.

[0049] Three gas regulating components are fixedly installed on the inner bottom of the housing 1. An electric lifting component is jointly installed between the three gas regulating components. Each of the three gas regulating components includes a base 25, and the base 25 is fixedly installed on the inner bottom of the housing 1 and fixedly connected to a connecting pipe 24. The top of the base 25 is fixedly connected to a cylinder body 23. A piston 30 is hermetically slid on the inner surface of the cylinder body 23. The top of the piston 30 is fixedly connected to a movable rod 29. A flow channel 31 penetrating to the side wall is opened at the top of the base 25, and both ends of the flow channel 31 communicate with the cylinder body 23 and the connecting pipe 24 respectively. The electric lifting component includes a motor 18, and the motor 18 is fixedly installed on the inner top of the housing 1. The driving end of the motor 18 is fixedly connected to a screw rod 19. A movable plate 20 is threadedly sleeved on the outer surface of the screw rod 19, and the movable plate 20 is fixedly connected between the three movable rods 29.

[0050] Three gas regulating components are provided inside the housing 1 for dynamically adjusting the buoyancy of the floating ball body 4. Each gas regulating component includes a base 25, a cylinder body 23, a piston 30, and a movable rod 29. The piston 30 hermetically slides inside the cylinder body 23 and is linked through the screw rod 19 driven by the motor 18 and the movable plate 20 to control the up and down movement of the piston 30, thereby inflating or deflating the floating ball body 4. The flow channel 31 and the connecting pipe 24 form a gas circulation path to ensure stable air pressure regulation. This design enables the floating ball to adapt to the changes in the oil layer and maintain the optimal oil pumping depth.

[0051] The outer surfaces of the three gas regulating components are all fixedly installed with connecting pipes 24. The top of the connecting pipe 24 is fixedly penetrated with a rotary joint 28. The movable ends of the three rotary joints 28 are all fixedly penetrated with hollow winding wheels 21. The winding ends of the three hollow winding wheels 21 are all fixedly penetrated with rubber hoses 6, and the rubber hoses 6 penetrate through the housing 1 and are fixedly penetrated between the fixed pipe 13 and the adjacent rubber hose 6. A resilient reset assembly is commonly installed between the three hollow winding wheels 21 and the housing 1. The three resilient reset assemblies each include a support shaft 27, and the support shaft 27 is fixedly connected to the adjacent hollow winding wheel 21. A support seat 22 is rotatably sleeved on the outer surface of the support shaft 27, and the support seat 22 is fixedly installed on the inner wall of one side of the housing 1. A volute spring 26 sleeved on the outer surface of the support shaft 27 is arranged inside the support seat 22, and the two ends of the volute spring 26 are respectively fixedly connected to the support shaft 27 and the support seat 22.

[0052] The three gas regulating components are communicated with the hollow winding wheels 21 through the connecting pipes 24. A rubber hose 6 is arranged inside the hollow winding wheel 21 for conveying or extracting gas to or from the float body 4. The support shaft 27 and the volute spring 26 constitute a resilient reset assembly. When the float moves, the rubber hose 6 is stretched or contracted, driving the hollow winding wheel 21 to rotate, and the volute spring 26 stores energy; when the float returns to its original position, the spring force makes the rubber hose 6 automatically retract, avoiding entanglement or knotting and improving the reliability of the equipment.

[0053] The controller 11 is fixedly installed on the top of the housing 1. The controller 11 is electrically connected to the oil extraction pump 10, the vibration type density sensor 14, and the motor 18, facilitating the control of the overall operation.

[0054] The controller 11 is integrated on the top of the housing 1 and is electrically connected to the oil extraction pump 10, the vibration type density sensor 14, and the motor 18. The controller 11 automatically adjusts the buoyancy of the float according to the sensor data and controls the start and stop of the oil extraction pump 10 to achieve fully automatic floating oil recovery. This design reduces manual intervention and is suitable for the continuous operation requirements of industrial sites.

[0055] Working principle: When in use, place the floating ball support in the oil tank or oil sump. During the movement of the floating ball support, it will pull one end of the rubber hose 6 to move. When one end of the rubber hose 6 moves, it will drive the hollow winding wheel 21 to rotate. The hollow winding wheel 21 drives the support shaft 27 to rotate, and the support shaft 27 drives the scroll spring 26 to deform. After the placement is completed, the density of the surface oil layer is detected by the vibration type density sensor 14, and then the signal is sent to the controller 11. The controller 11 controls the operation of the motor 18. The motor 18 drives the screw 19 to rotate, and the screw 19 drives the movable plate 20 to rise or fall. The movable plate 20 synchronously drives the three movable rods 29 to rise or fall, and the movable rods 29 drive the piston 30 to rise or fall. The piston 30 cooperates with the cylinder body 23, and through the flow channel 31, the connecting pipe 24, the rotary joint 28, the hollow winding wheel 21, the rubber hose 6 and the fixed pipe 13, the three floating ball bodies 4 are evacuated and inflated, changing the buoyancy of the three floating ball bodies 4 until the required state is reached. Make the top opening of the funnel 15 be about 1 cm below the water surface, and then the oil pump 10 operates. The oil pump 10 extracts the top layer of oil through the inlet pipe 8, the hose 7 and the funnel 15, and then discharges it through the drain pipe 9. The drain pipe 9 can be connected to the pipeline of the external floating oil recovery and treatment equipment for subsequent treatment.
