Description

Technical Field

[0001] This utility model relates to the technical field of sewage treatment equipment, and more specifically, to an oil floating removal device. Background Technology

[0002] In the gas field's water tanks, lubricating oil is added to drilling equipment during use. This lubricating oil returns to the surface with the extracted water and accumulates in the water tanks. Initially, a small amount of grease exists in a suspended form in the water, making it easy to remove. However, most of the grease exists in an emulsified or dissolved state, slowly accumulating into large grease particles over a long period of time in a stagnant environment, gradually becoming visible as surface oil. To ensure water quality meets standards, the water tanks must be emptied periodically, and workers enter the bottom of the tanks to use suction pumps to remove the surface oil.

[0003] Because gas field water pools are numerous, widely distributed, and of various forms, floating oil is generated irregularly, requiring repeated cleaning. During the cleaning process, the water pool needs to suspend the discharge of return water. After the water in the pool is emptied, personnel are sent into the pool to clean the floating oil and suspend the discharge of return water again. This not only involves the usage arrangement of the gas field water pool and the corresponding well, but also requires the allocation of personnel for cleaning. The entire cleaning operation requires a lot of time and manpower, which is inconvenient. Utility Model Content

[0004] The purpose of this utility model is to provide a floating oil removal device, which solves the problems of the current method of cleaning floating oil in gas field pools, which requires a lot of time and manpower costs to send people into the pool for cleaning after draining the water, and the inconvenience of cleaning.

[0005] This utility model is achieved through the following technical solution: an oil floating removal device, including a frame, on which a conveyor belt is inclinedly arranged, the conveyor belt including a low-speed motor, an oil suction strip and a plurality of rotating rollers, the plurality of rotating rollers being rotatably arranged on the frame, and the oil suction strip being wound around the plurality of rotating rollers and connected end to end;

[0006] The low-speed motor is mounted on the frame, and the output end of the low-speed motor is connected to one of the rotating rollers.

[0007] The frame is also provided with an oil collection trough, and an oil scraper is provided in the middle of the opening of the oil collection trough. The oil scraper slides against the bottom part of the oil suction strip.

[0008] The frame is provided with a circular array of several floating elements, which are used to provide buoyancy to the frame.

[0009] Furthermore, the conveyor belt also includes several synchronous belts, which are disposed inside the oil suction bar, and several synchronous pulleys are fitted on the rollers, with the synchronous belts meshing with the synchronous pulleys.

[0010] Furthermore, the oil scraper component includes a support frame, a lower scraper, an upper scraper, and a spring, with the support frame mounted on the opening of the oil collection trough;

[0011] The upper scraper is fixed on the support frame, and the lower scraper is located below the upper scraper. Both ends of the lower scraper are provided with springs, and the two ends of the springs are respectively connected to the upper scraper and the lower scraper. The oil-absorbing strip passes through the space between the upper scraper and the lower scraper, and both the upper scraper and the lower scraper abut against the oil-absorbing strip.

[0012] Furthermore, the floating component includes a cylinder, a piston, and a driving component. The cylinder is vertically mounted on the frame and has an opening at its lower end. The piston is slidably mounted inside the cylinder, and the driving component is mounted on the cylinder and is used to drive the piston to move within the cylinder.

[0013] Furthermore, the driving component includes a drive motor, a screw, and a drive sleeve, and the piston is slidably disposed in the inner cavity of the cylinder and connected to the cylinder via a spline;

[0014] The drive sleeve is rotatably disposed inside the cylinder, the output end of the drive motor is connected to the drive sleeve for transmission, the lower end of the screw is coaxially connected to the piston, and the upper end of the screw is placed inside the drive sleeve and threadedly engaged with the drive sleeve.

[0015] Furthermore, it also includes an underwater thruster, which is also mounted on the frame.

[0016] Furthermore, it also includes a servo motor, the underwater thruster is rotatably mounted on the frame via a rotating shaft, and the output end of the servo motor is connected to the rotating shaft via a transmission connection.

[0017] The technical solution of this utility model has at least the following advantages and beneficial effects:

[0018] 1. The highest point of the two front rollers is usually in the water and below the oil layer, while the two rear rollers are higher than the oil layer. This ensures that the inclined oil suction bar can always be in contact with the oil layer as it moves forward. A low-speed motor is mounted on the frame, and its output is connected to one of the rollers. The low-speed motor drives the upper surface of the entire oil suction bar to move from the lower side to the higher side. At the same time, the oil adsorbed by the oil suction bar is transported to the higher side and then collected.

[0019] 2. The upper scraper slides against the inner side of the oil suction strip via a support frame, while the lower scraper is pulled by springs on both sides, causing it to abut against the outer side of the oil suction strip, effectively clamping it. The upper and lower scrapers clamp the oil suction strip, not only squeezing it but also allowing the oil squeezed out and scraped off to fall smoothly into the oil collection tank. When the oil collection tank is almost full, the oil can be cleaned out until the oil in the entire pool is basically cleaned. This device automatically collects oil, eliminating the need for drainage and cleaning, and does not affect the normal backflow operation of the pool, saving time and reducing manpower. It is very simple and convenient for collecting oil.

[0020] 3. When the drive sleeve rotates, the screw pushes the piston to move inside the cylinder under the action of the drive sleeve, thereby controlling the size of the space above the piston inside the cylinder, so as to control the buoyancy of the entire floating component. By controlling the buoyancy of all the floating components, the required draft of the entire device can be adjusted. As the weight of the entire device will gradually increase during the oil collection process, in order to ensure that the oil suction bar can stably suck up oil, it is necessary to control the buoyancy generated by several floating components so that the height of the frame in the water does not change much.

[0021] 4. The driving direction of the underwater propulsion unit is adjusted by the servo motor, thereby controlling the movement direction of the entire device. A battery or cable can be installed on the frame to provide power. The low-speed motor, underwater propulsion unit, servo motor, and several drive motors are all controlled by a processor and can be operated remotely via wireless remote control, making control and movement more convenient.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0029] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] Reference Figures 1 to 4 As shown, this embodiment provides an oil spill removal device, including a frame 1. A conveyor belt 2 is inclinedly arranged on the frame 1. The conveyor belt 2 includes several rotating rollers 23, a low-speed motor 21, and oil suction strips 22. The rotating rollers 23 are all rotatably arranged on the frame 1, and the oil suction strips 22 are wound around the rotating rollers 23 and connected end to end. In specific implementation, four rotating rollers 23 are usually provided, two at the front end of the frame 1 and two at the rear end of the frame 1. The height of the two rotating rollers 23 at the front end of the frame 1 is lower than that of the two rotating rollers 23 at the rear end of the frame 1, so that the rated oil suction strips stretched on the four rotating rollers 23 are more efficient. 22 remains tilted. The highest points of the two front rollers 23 are usually in the water and below the oil layer, while the two rear rollers 23 are higher than the oil layer. Thus, the tilted oil suction strip 22 can always contact the oil layer during its forward movement. The low-speed motor 21 is mounted on the frame 1, and its output is connected to one of the rollers 23. The low-speed motor 21 drives the upper surface of the entire oil suction strip 22 to move from the lower side to the higher side. At the same time, the oil adsorbed by the oil suction strip 22 is transported to the higher side and then collected.

[0031] More specifically, such as Figures 1-3 As shown, the conveyor belt 2 also includes several synchronous belts 24, which are arranged inside the oil suction bar 22. Synchronous pulleys 25 are fitted onto several rotating rollers 23, and the synchronous belts 24 mesh with the synchronous pulleys 25. In specific implementations, there are at least two synchronous belts 24. The width of the synchronous pulleys 25 is not less than the width of the oil suction bar 22. The synchronous pulleys 25 have external teeth, while the inner side of the synchronous belts 24 contains tooth grooves. The synchronous belts 24 are wound around four synchronous pulleys 25, and the tooth grooves mesh with the external teeth. Thus, the low-speed motor 21 can synchronously drive the four rotating rollers 23 to rotate, and simultaneously drive the entire oil suction bar 22 to rotate synchronously. As the oil suction bar 22 rotates with the synchronous belts 24, it carries the floating oil and separates it from the water for subsequent collection of the floating oil.

[0032] like Figures 1-3 As shown, the frame 1 is also equipped with an oil collection trough 3. An oil scraper 4 is installed in the middle of the opening of the oil collection trough 3. The oil scraper 4 slides against the bottom portion of the oil suction strip 22, thereby scraping off the floating oil on the oil suction strip 22 and collecting it in the oil collection trough 3. Specifically, the oil scraper 4 includes a support frame 41, a lower scraper 42, an upper scraper 43, and a spring 44. The support frame 41 is mounted on the opening of the oil collection trough 3. The upper scraper 43 is fixed to the support frame 41, and the lower scraper 42 is located below the upper scraper 43. Springs 44 are installed at both ends of the lower scraper 42, and the two ends of the springs 44 are connected to the upper scraper 43 and the lower scraper 42, respectively. The oil suction strip 22 passes between the upper scraper 43 and the lower scraper 42, and both the upper scraper 43 and the lower scraper 42 abut against the oil suction strip 22. The upper scraper 43 slides against the inner side of the oil-absorbing strip 22 via the support frame 41, while the lower scraper 42 is pulled by the springs 44 on both sides, causing the lower scraper 42 to abut against the outer side of the oil-absorbing strip 22, which is equivalent to clamping the oil-absorbing strip 22. The upper scraper 43 and the lower scraper 42 clamp the oil-absorbing strip 22, which not only squeezes the oil-absorbing strip 22, but also allows the floating oil squeezed out and scraped off on the oil-absorbing strip 22 to fall smoothly into the oil collection tank 3. When the floating oil collected in the oil collection tank 3 is almost full, the floating oil in the oil collection tank 3 can be cleaned out until the floating oil in the entire pool is basically cleaned up. The automatic collection of floating oil by this device not only eliminates the need to drain and clean, but also does not affect the normal backflow operation of the pool, saving time and reducing the use of manpower. The collection of floating oil is very simple and convenient.

[0033] More specifically, such as Figure 1 and Figure 4As shown, several floating elements 5 are arranged in a circular array on the frame 1. The floating elements 5 are used to provide buoyancy to the frame 1. The buoyancy generated by the floating elements 5 makes the frame 1 suspend in the water, ensuring that the lower end of the conveyor belt 2 is placed in the water below the oil layer and the higher end of the conveyor belt 2 is above the oil layer. At the same time, the opening of the oil collection tank 3 needs to be located above the oil layer, thus providing a basic guarantee for the smooth cleaning of the oil layer in the future.

[0034] The floating component 5 includes a cylinder 51, a piston 52, and a drive component 53. The cylinder 51 is vertically mounted on the frame 1, and an opening 511 is provided at the lower end of the cylinder 51. The piston 52 is slidably mounted inside the cylinder 51, and the drive component 53 is mounted on the cylinder 51. The drive component 53 is used to drive the piston 52 to move inside the cylinder 51. The lower end of the cylinder 51 is connected to the water tank. The position of the piston 52 inside the cylinder 51 is controlled by the drive component 53, thereby controlling the buoyancy generated by the floating component 5. Since the weight of the entire device will gradually increase during the oil collection process, in order to ensure that the oil suction bar 22 can stably suck up oil, it is necessary to control the buoyancy generated by several floating components 5 so that the height of the frame 1 in the water does not change much.

[0035] More specifically, such as Figure 1 and Figure 4 As shown, the driving component 53 includes a driving motor 531, a screw 532, and a driving sleeve 533. The piston 52 is slidably disposed in the inner cavity of the cylinder 51 and splinedly connected to the cylinder 51. The driving sleeve 533 is rotatably disposed in the cylinder 51. The output end of the driving motor 531 is connected to the driving sleeve 533 for transmission. The lower end of the screw 532 is coaxially connected to the piston 52, and the upper end of the screw 532 is placed in the driving sleeve 533 and threadedly engaged with the driving sleeve 533. In practice, the top of the cylinder 51 is basically sealed with only some vent holes. The drive sleeve 533 is coaxially arranged with the cylinder 51. The drive motor 531 drives the drive sleeve 533 to rotate. Since the piston 52 is splined to the inner wall of the sleeve, the piston 52 cannot rotate coaxially inside the sleeve. When the drive sleeve 533 rotates, the screw 532 pushes the piston 52 to move inside the cylinder 51 under the action of the drive sleeve 533, thereby controlling the size of the space above the piston 52 inside the cylinder 51, so as to control the buoyancy of the entire floating component 5. By controlling the buoyancy of all the floating components 5, the required draft of the entire device can be adjusted.

[0036] More specifically, such as Figure 1As shown, it also includes an underwater thruster 6, which is mounted on the frame 1. It also includes a servo motor 7. The underwater thruster 6 is rotatably mounted on the frame 1 via a rotating shaft 61, and the output end of the servo motor 7 is connected to the rotating shaft 61. The servo motor 7 adjusts the driving direction of the underwater thruster, thereby controlling the movement direction of the entire device. A battery or cable can be installed on the frame 1 to provide power. The low-speed motor 21, underwater thruster 6, servo motor 7, and several drive motors 531 are all controlled by a processor, allowing for wireless remote control operation, making control and movement more convenient. Alternatively, at least two ropes can be used to tie the sides of the frame 1, allowing manual control of the frame 1's position in the pool.

[0037] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
