Description

Technical Field

[0001] This invention relates to the field of oil transportation anti-static pipe maintenance technology, specifically to an online anti-static pipe cleaning device and its usage method. Background Technology

[0002] Electrostatic discharge (ESD) protection during oil transportation is a crucial technology in the petrochemical and shipbuilding industries. Existing pipeline ESD eliminators, due to their use of insulated polymer inner tubes, require periodic cleaning of the pipeline's inner wall to ensure their effectiveness. In the design of marine oil transportation pipelines, the ESD eliminator is connected to the oil pipeline via tenon-and-mortise flanges, which poses significant challenges to disassembly and cleaning.

[0003] CN115716074A discloses a cleaning device and method in a non-removal state. The method involves adding a complex cleaning device to an existing pipeline static eliminator, which greatly increases the cost of the static eliminator tube. During cleaning, all static eliminator needles need to be disassembled and the needle holes plugged with threads. This disassembly work requires operating space around the equipment and is more extensive and complex than disassembling the entire static eliminator tube. The maintenance of the additional cleaning mechanism itself also brings more problems.

[0004] To address the above problems, this invention proposes an online cleaning device and method. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides an online cleaning device and method for electric shock ducts, which has the advantages of simple structure, convenient operation, and low maintenance cost. It solves the problems of existing electric shock ducts needing to be disassembled for cleaning or requiring the addition of cleaning mechanisms that are more complex and costly than the electric shock duct itself.

[0007] (II) Technical Solution

[0008] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: an online cleaning device for the electrostatic discharge pipe, including an external cleaning machine and an electrostatic discharge pipe connector, wherein the external cleaning machine is composed of an oil pump, an oil tank, a filter, an inert gas tank, a peristaltic component drive assembly, and a peristaltic mechanism;

[0009] The current-extinguishing pipe connector consists of a valve, an upper interface, and a lower interface. The upper interface and the lower interface are located close to their connection ends and are distributed vertically.

[0010] The extension end of the peristaltic drive assembly is connected to the outside of the peristaltic mechanism;

[0011] The inlet end of the oil pump extends to the bottom wall of the oil tank through a pipe, and the delivery end of the oil pump is connected to the peristaltic mechanism through a high-pressure pipe.

[0012] The inert gas tank is externally equipped with a pressure valve and a gas pipeline, which is connected to the peristaltic mechanism.

[0013] The oil tank is provided with a return pipe extending into its interior, and quick connectors are provided at both the other end of the return pipe and the lower interface.

[0014] Both the upper interface and the peristaltic mechanism are provided with flanges on their exteriors.

[0015] The filter is fixed at the connection between the oil tank and the return pipe.

[0016] The beneficial effects of this invention are:

[0017] The online cleaning device for extinguishing current pipes and its usage method have the advantages of cleaning the inside of the extinguishing current pipes without disassembly, convenient cleaning process, and easy cleaning of multiple extinguishing current pipes by moving the cleaning device.

[0018] Based on the above technical solution, the present invention can be further improved as follows.

[0019] Furthermore, the peristaltic mechanism consists of a peristaltic frame and a connecting shell, with the peristaltic frame snapped into the inside of the connecting shell and the flange located outside the connecting shell.

[0020] The advantage of adopting the above-mentioned further solution is that the above-mentioned arrangement allows the peristaltic mechanism to be easily connected to the upper interface.

[0021] Furthermore, the peristaltic drive assembly consists of a power motor, a winding frame, and a composite push cable. The two ends of the composite push cable are fixed to the peristaltic frame and the winding frame, respectively, and the winding frame is fixedly connected to the output shaft of the power motor.

[0022] The beneficial effect of adopting the above-mentioned further solution is that the composite push cable can easily push the peristaltic frame, making the peristaltic frame easy to move.

[0023] Furthermore, the peristaltic frame consists of a connecting pipe, a guide wheel assembly, and a nozzle. The nozzle is arranged outside the connecting pipe and faces the inner wall of the oil dissipation pipe. There are two guide wheel assemblies, which are respectively fixed at both ends of the connecting pipe.

[0024] Furthermore, the guide wheel assembly consists of no fewer than three telescopic guide wheels and a connecting frame, with the three telescopic guide wheels arranged in a circular array on the outside of the connecting frame.

[0025] The advantage of adopting the above-mentioned further solution is that the setting of no less than three telescopic guide wheels provides better support, ensuring that the nozzle is always located in the center.

[0026] Furthermore, the anti-static needles and the telescopic guide wheels are staggered.

[0027] The advantage of adopting the above-mentioned further solution is that it can prevent the extinguishing needle from colliding with the peristaltic frame.

[0028] Furthermore, the lower interface is connected to a pressure relief valve via a quick-connect coupling.

[0029] The advantage of adopting the above-mentioned further solution is that the pressure relief valve facilitates the discharge of internal inert gas.

[0030] The cleaning method includes the following steps:

[0031] S1. Close the oil circuit and shut off the valves on both sides of the oil de-energizing pipe;

[0032] S2. Prepare for oil recovery. Connect the peristaltic mechanism to the upper interface via a flange, and connect the return pipe to the lower interface via a quick connector.

[0033] S3. Drain the oil and return the oil in the power-off pipe to the cleaning machine's oil tank through the lower interface.

[0034] S4. Inert gas filling: Inert gas is used to fill the inside of the oil extinguishing pipe through a gas tank.

[0035] S5. Clean the pipe wall, release the peristaltic frame, push it through the peristaltic drive assembly, and pump out the oil through the oil pump to flush the inner wall;

[0036] S6. After cleaning is completed, the peristaltic frame is retracted by the peristaltic drive assembly, and the connector between the upper and lower interfaces is removed. Then, the valves at both ends of the oil extinguishing pipe are opened. Attached Figure Description

[0044] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] In the embodiments, by Figure 1-6 The present invention provides an online cleaning device for the electrostatic discharge pipe and its usage method. The present invention includes an external cleaning machine and an electrostatic discharge pipe connector. The external cleaning machine consists of an oil pump 1, an oil tank 2, a filter 3, an inert gas tank 4, a peristaltic component drive assembly 5, and a peristaltic mechanism 6.

[0046] The current-extinguishing pipe connector consists of a valve 7, an upper interface 8, and a lower interface 9. The upper interface 8 and the lower interface 9 are located close to their connection ends and are distributed vertically.

[0047] The connection end of the extinguishing pipe connector is directly connected to the extinguishing pipe through a flange and fasteners;

[0048] The extension end of the peristaltic drive assembly 5 is externally connected to the peristaltic mechanism 6;

[0049] The inlet end of the oil pump 1 extends to the bottom wall of the oil tank 2 through a pipe, and the delivery end of the oil pump 1 is connected to the peristaltic mechanism 6 through a high-pressure pipe.

[0050] The inert gas tank 4 is externally equipped with a pressure valve and a gas pipeline 11, which is connected to the peristaltic mechanism 6.

[0051] The oil tank 2 is provided with a return pipe 10 extending into its interior, and the other end of the return pipe 10 and the lower interface 9 are both provided with quick connectors.

[0052] Both the upper interface 8 and the peristaltic mechanism 6 are equipped with flanges on the outside;

[0053] The filter 3 is fixed at the connection between the oil tank 2 and the return pipe 10.

[0054] The peristaltic mechanism 6 consists of a peristaltic frame 61 and a connecting shell 62. The peristaltic frame 61 is snapped into the inside of the connecting shell 62, and the flange is located outside the connecting shell 62.

[0055] The above configuration allows the peristaltic mechanism 6 to be easily connected to the upper interface 8.

[0056] The connection between the peristaltic frame 61 and the peristaltic shell can be magnetic. By setting a magnetic rod on the inside of the connecting shell 62 and a magnetic ring on the outside of the peristaltic frame 61, the frame can be locked by magnetic force.

[0057] When connected using the above locking method, the magnetic ring consists of a plastic ring and a metal adsorption column. The magnetic points of the metal adsorption column can be set, allowing the telescopic guide wheel and the anti-static needle to be staggered.

[0058] The peristaltic drive assembly 5 consists of a power motor, a winding frame, and a composite push cable. The two ends of the composite push cable are fixed to the peristaltic frame 61 and the winding frame, respectively, and the winding frame is fixedly connected to the output shaft of the power motor.

[0059] The composite propulsion cable consists of multiple strands of steel wire rope and an outer rubber sheath, the outer surface of which is coated with a hardened coating.

[0060] The composite push cable can easily push the peristaltic frame 61, making the peristaltic frame 61 easy to move.

[0061] The peristaltic frame 61 consists of a connecting pipe, a guide wheel assembly, and a nozzle. The nozzle is located outside the connecting pipe and faces the inner wall of the oil dissipation pipe. There are two guide wheel assemblies, which are fixed at both ends of the connecting pipe respectively.

[0062] The guide wheel assembly consists of no fewer than three telescopic guide wheels and a connecting frame, with multiple telescopic guide wheels arranged in a circular array on the outside of the connecting frame.

[0063] There are multiple nozzles arranged in a ring array outside the connecting pipe. The nozzles are arranged in a divergent pattern along the connecting pipe, and the nozzles closer to the guide wheel assembly spray in the direction of the guide wheel assembly.

[0064] The installation of at least three telescopic guide wheels provides good support, ensuring that the nozzle is always centered.

[0065] This also includes an oil extinguishing pipe, which is externally fixedly connected to extinguishing needles extending into its interior. The number of extinguishing needles is multiple and they are arranged in a ring array around the axis of the oil extinguishing pipe.

[0066] The static-eliminating needles and telescopic guide wheels are staggered.

[0067] Specifically, the static elimination needles are divided into multiple groups, and the arrangement of these groups is a circular array. The number of telescopic guide wheels in a single guide wheel group should be consistent with the number of static elimination needle groups.

[0068] This prevents the static-eliminating needle from colliding with the peristaltic frame 61.

[0069] The lower interface 9 is connected to a pressure relief valve via a quick connector.

[0070] The pressure relief valve allows for the convenient discharge of internal inert gas.

[0071] The cleaning method includes the following steps:

[0072] S1. Close the oil circuit and close valves 7 on both sides of the oil de-energizing pipe;

[0073] S2. Prepare for oil recovery. Connect the peristaltic mechanism 6 to the upper interface 8 through a flange, and connect the return pipe 10 to the lower interface 9 through a quick connector.

[0074] S3. Drain the oil and return the oil in the power-off pipe to the cleaning machine oil tank 2 through the lower interface 9.

[0075] S4. Inert gas filling: Inert gas is used to fill the inside of the oil extinguishing pipe through a gas tank.

[0076] S5. Clean the pipe wall, release the peristaltic frame 61, push it through the peristaltic drive assembly 5, and pump out the oil through the oil pump 1 to flush the inner wall.

[0077] S6. After cleaning is completed, the peristaltic frame 61 is retracted by the peristaltic drive assembly 5, and the connector between the upper interface 8 and the lower interface 9 is removed. Then, the valves 7 at both ends of the oil extinguishing pipe are opened.
