Description

Technical Field

[0001] This utility model relates to the field of oil rod recycling technology, and in particular to a device for remanufacturing waste oil rods. Background Technology

[0002] Sucker rods are the core components of oil extraction. They are mostly made of low-carbon alloy steel and need to penetrate thousands of meters underground to transmit power. Oil fields in my country generally face problems such as high water content and high mineralization in oil wells, resulting in severe electrochemical corrosion. In addition, the increase in deviated wells and horizontal wells has led to increased wear on sucker rods, causing a large number of sucker rods to be scrapped prematurely.

[0003] However, in the existing waste oil rod recycling process, most companies still rely on manual handheld high-pressure water gun rinsing or simple soaking and brushing. This cleaning method is not only inefficient due to low manual operation and time-consuming cleaning of a single oil rod, making it difficult to adapt to the needs of large-scale recycling and processing, but also has extremely unstable cleaning effect. It can only remove surface dirt and cannot completely remove firmly attached sludge, scale, and deep rust. The residual contaminants can also affect the accuracy of subsequent flaw detection and repair processes, leading to potential quality problems in remanufactured products. To address this, we propose a waste oil rod remanufacturing device that adopts a multi-station linkage cleaning mechanism, integrating high-pressure spraying, ultrasonic cleaning, and hot air drying modules. Through PLC control, the temperature and pressure of the cleaning fluid are adaptively adjusted to remove oil, rust, and scale from the surface of the oil rod, thus solving the above problems.

[0007] As an improved technical solution, the control box is equipped with a PLC controller, which is electrically connected to the high-pressure spray chamber, ultrasonic cleaning chamber, hot air drying chamber, servo motor, lifting cylinder and rotary motor.

[0008] As an improved technical solution, the high-pressure spray chamber is equipped with multiple high-pressure nozzles, which are connected to a liquid storage tank via pipes.

[0012] After adopting the above technical solution, the beneficial effects of this utility model are: I. This utility model integrates the high-pressure spray chamber, ultrasonic cleaning chamber, and hot air drying chamber into the main body of the cleaning tank, thereby improving the automation level of the equipment, reducing manual intervention, allowing high-pressure spraying to effectively remove surface dirt, ultrasonic cleaning to thoroughly remove deep contaminants, and hot air drying to ensure surface cleanliness and dryness.

[0016] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0017] This utility model provides a technical solution: such as Figures 1 to 4 As shown in this embodiment, a waste oil rod remanufacturing device includes a cleaning tank body 1, a liquid storage tank 2 installed on the left side of the cleaning tank body 1, a control box 3 installed at the front end of the liquid storage tank 2, a high-pressure spray chamber 4, an ultrasonic cleaning chamber 5 and a hot air drying chamber 6 respectively arranged from left to right inside the cleaning tank body 1, an ultrasonic vibrating plate 7 installed inside the ultrasonic cleaning chamber 5, a hot air outlet 8 installed inside the hot air drying chamber 6, a hot air fan 9 installed outside the front end of the hot air drying chamber 6, a guide rail 10 installed at the rear end of the cleaning tank body 1, a fixed seat 17 connected to the guide rail 10 through a horizontal drive component, a rotary motor 19 installed inside the fixed seat 17, a mounting base 11 installed at the output end of the rotary motor 19, a lifting cylinder 12 installed at the top of the mounting base 11, and an oil rod clamping wheel 13 installed at the output end of the lifting cylinder 12.

[0018] The used oil rod is held by the oil rod clamping wheel 13, and the horizontal drive component drives the fixed seat 17 to move horizontally along the guide rail 10, so that the oil rod is sent into the high pressure spray chamber 4, the ultrasonic cleaning chamber 5 and the hot air drying chamber 6 for treatment in sequence. The high pressure spray chamber 4 is used to initially rinse the oil sludge and floating dirt on the surface of the oil rod. The ultrasonic cleaning chamber 5 generates high frequency vibration through the ultrasonic transducer 7, forming a cavitation effect in the cleaning fluid, which deeply removes the scale and rust layer on the surface of the oil rod. The hot air drying chamber 6 blows hot air out through the hot air outlet 8 and the hot air fan 9 to dry the oil rod. Then, the rotary motor 19 drives the oil rod to rotate, so that the oil rod is away from the top of the main body 1 of the cleaning tank. The lifting cylinder 12 adjusts the height of the oil rod clamping wheel 13 to adapt to oil rods of different diameters.

[0019] In other embodiments, the horizontal drive assembly includes a transmission screw 14 rotatably connected in the guide rail 10, a servo motor 15 mounted on the right end of the guide rail 10, the output end of the servo motor 15 connected to the end of the transmission screw 14, a guide slider 16 provided in the guide rail 10, a threaded groove 18 provided on the guide slider 16, the transmission screw 14 being threadedly connected to the threaded groove 18, and a fixing seat 17 fixed to the top of the guide slider 16. By installing a horizontally movable guide slider 16 inside the guide rail 10, the servo motor 15 can drive the transmission screw 14 to rotate. Since the transmission screw 14 is threadedly connected to the threaded groove 18 on the guide slider 16, the guide slider 16 moves horizontally inside the guide rail 10, thereby driving the fixed seat 17 to move horizontally. This can accurately position the oil rod to different work positions, realize the automated cleaning process, avoid the instability of manual operation, and improve production efficiency.

[0020] In other embodiments, a PLC controller is provided in the control box 3. The PLC controller is electrically connected to the high-pressure spray chamber 4, the ultrasonic cleaning chamber 5, the hot air drying chamber 6, the servo motor 15, the lifting cylinder 12, and the rotary motor 19. This design allows the PLC controller to automatically adjust the spray pressure, cleaning fluid temperature, and spray time of the high-pressure spray chamber 4 according to a preset program; control the ultrasonic frequency, power, and cleaning time of the ultrasonic cleaning chamber 5; and control the hot air temperature, wind speed, and drying time of the hot air drying chamber 6. Simultaneously, it controls the moving speed of the servo motor 15, the lifting height of the lifting cylinder 12, and the rotation speed of the rotary motor 19, achieving fully automated cleaning.

[0021] In other embodiments, the high-pressure spray chamber 4 is provided with multiple high-pressure nozzles, which are connected to the liquid storage tank 2 through pipes. A water pump and a heater are provided on the pipes, and the water pump and heater are electrically connected to the control box 3. This design allows the water pump to draw cleaning fluid from the storage tank 2, which is then heated by a heater and sprayed onto the oil rod surface through a high-pressure nozzle as a high-pressure, high-temperature water jet. This impacts and softens the sludge, floating dirt, and some scale. Heating the cleaning fluid enhances its cleaning power and improves cleaning efficiency, avoiding the problem of inconsistent results from traditional manual rinsing.

[0022] In other embodiments, a plurality of ultrasonic transducers 7 are installed on the bottom and sidewalls of the ultrasonic cleaning chamber 5, and the ultrasonic transducers 7 are connected to an ultrasonic generator; This design allows the ultrasonic generator to drive the ultrasonic transducer plate 7 to produce high-frequency vibrations, creating a cavitation effect in the cleaning fluid and generating a large number of tiny bubbles. When the bubbles burst, they release shock waves that penetrate deep into the gaps and micropores on the surface of the oil rod, peeling off and removing stubborn contaminants such as scale and rust. The evenly distributed ultrasonic transducer plate 7 ensures thorough cleaning of the oil rod, improving the quality and reliability of remanufactured products.

[0023] In other embodiments, the hot air outlet 8 is connected to the hot air blower 9 via a duct, and the hot air blower 9 is electrically connected to the control box 3; This design allows the hot air blower 9 to generate hot air, which is then evenly blown onto the surface of the oil rod through the hot air outlet 8. This evaporates residual moisture and cleaning fluid, achieving rapid drying and ensuring that the surface of the oil rod is clean and dry, facilitating subsequent flaw detection, repair, and other processes.

[0024] In other embodiments, the outer wall of the guide slider 16 is fully fitted with the inner wall of the guide rail 10, and the guide slider 16 and the guide rail 10 are slidably connected. With this design, when the guide slider 16 slides within the guide rail 10, the outer wall is fully in contact with the inner wall of the guide rail 10, reducing wobbling and offset, and ensuring smooth horizontal movement. When the transmission screw 14 drives the guide slider 16 to move, the fixed seat 17 moves precisely accordingly, improving the stability and accuracy of the oil rod transmission.

[0025] This utility model provides a device for remanufacturing waste oil rods, the specific working principle of which is as follows: The waste oil rod is clamped and fixed by the oil rod clamping wheel 13. The lifting cylinder 12 adjusts the clamping height to accommodate oil rods of different diameters. The rotary motor 19 drives the oil rod to rotate slowly to ensure full contact with the cleaning medium. Then, the servo motor 15 drives the transmission screw 14 to rotate, which drives the guide slider 16 and the fixed seat 17 to move horizontally along the guide rail 10, sending the oil rod into the high-pressure spray chamber 4, the ultrasonic cleaning chamber 5 and the hot air drying chamber 6 in sequence.

[0026] The oil rod first enters the high-pressure spray chamber 4. The high-pressure nozzle draws cleaning fluid from the storage tank 2. After being pressurized by the water pump and heated by the heater, the high-pressure, high-temperature water jet sprays onto the surface of the oil rod, impacting and softening the sludge, floating dirt, and some scale.

[0027] The oil rod is then introduced into the ultrasonic cleaning chamber 5, which is filled with cleaning fluid. The ultrasonic transducer 7 vibrates under the drive of a high-frequency electrical signal, creating a cavitation effect in the cleaning fluid and generating microbubbles. When the bubbles burst, they release shock waves that penetrate deep into the gaps and micropores on the surface of the oil rod, thoroughly removing stubborn contaminants such as scale and rust.

[0028] The oil rod finally enters the hot air drying chamber 6, where the hot air fan 9 generates hot air, which is then blown evenly onto the surface of the oil rod through the hot air outlet 8 to evaporate residual moisture and cleaning solution, achieving rapid drying.

[0029] The electrical components and main controllers mentioned in this article can all be conventional, known devices such as computers that provide control.

[0030] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
