However, in the actual process of draining the flushing oil, not only is a large amount of flushing oil discharged and collected, causing pollution and waste, but it also poses safety and environmental protection hazards. Therefore, a device with a supplementary flushing oil recovery function is needed. Utility Model Content

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-4 This utility model provides a new technical solution: a device for supplementing the function of flushing oil recovery, including a first fixed plate 1: the first fixed plate 1 is the core bearing foundation of the device, a second fixed plate 2 is fixedly connected to the left side of the first fixed plate 1, a nitrogen tank 12 is fixedly connected to the upper surface of the first fixed plate 1, and two moving wheels 13 are fixedly connected to the lower surface of the first fixed plate 1. The first fixed plate 1 provides a stable installation support for the nitrogen tank 12 and the second fixed plate 2. The connection with the second fixed plate 2 forms a component installation frame. The moving wheels 13 on the lower surface cooperate to realize the flexible movement of the whole device and adapt to different working sites.

[0017] Second fixed plate 2: The second fixed plate 2 is an integrated mounting carrier for the flushing assembly, providing a horizontal mounting reference for the pressure reducing valve, check valve and shut-off valve, ensuring smooth pipeline connection. The lower surface moving wheel 13 works in conjunction with the moving wheel of the first fixed plate 1 to improve the mobility of the device.

[0018] Nitrogen tank 12: Nitrogen tank 12 is the core of the gas supply for flushing oil recovery. It provides high-pressure nitrogen to the entire system and delivers the nitrogen to the subsequent regulating components through the second hose 8 at the outlet end, ensuring a continuous and stable gas supply during the recovery process.

[0019] Second hose 8: The second hose 8 is the nitrogen delivery channel from nitrogen tank 12 to adjustable gas pressure reducing valve 11. Its flexible characteristics adapt to the installation position of nitrogen tank and pressure reducing valve to ensure that nitrogen delivery is leak-free.

[0020] Adjustable gas pressure reducing valve 11: The adjustable gas pressure reducing valve 11 is the core of nitrogen pressure and flow regulation. It can set appropriate parameters by adjusting the knob according to the diameter, length and viscosity of the flushing pipeline and the flushing oil, so as to avoid the pipeline being damaged by excessive pressure or the pipeline being damaged by excessive pressure or the pipeline being damaged by insufficient pressure.

[0021] Third hose 10: The third hose 10 is a transitional delivery channel for nitrogen after pressure reduction. It stably delivers the nitrogen after adjustment by the adjustable gas pressure reducing valve 11 to the one-way valve 9, ensuring continuous gas flow.

[0022] One-way valve 9: The output end of one-way valve 9 is fixedly connected to the first hose 3. One-way valve 9 has one-way conduction characteristics, which can prevent the flushing oil from flowing back into the nitrogen system due to pressure fluctuations during the purging process, avoid the nitrogen tank 12 and pressure reducing valve and other components from being contaminated by oil, and ensure the cleanliness of the nitrogen system.

[0023] First hose 3: First hose 3 is the nitrogen delivery channel from check valve 9 to high pressure shut-off valve 4. The flexible connection adapts to the installation distance of the two components to ensure smooth and unobstructed gas delivery.

[0024] High-pressure shut-off valve 4: The output end of the high-pressure shut-off valve 4 is fixedly connected to the fixed pipe 7. The high-pressure shut-off valve 4 is the on-off control component for nitrogen gas delivery. It can be closed before operation to prevent nitrogen gas from flowing into the flushing oil pipe in advance. It can be opened during operation to allow nitrogen gas to enter the subsequent pipeline, thereby achieving precise control of nitrogen gas delivery.

[0025] Fixed pipe 7: Fixed pipe 7 is a rigid connecting pipe between high pressure shut-off valve 4 and spiral hose 6, providing stable pipeline support for nitrogen delivery and avoiding loosening of the joint caused by direct connection of flexible hose to shut-off valve.

[0026] Spiral hose 6: Spiral hose 6 has good flexibility and extensibility, which can adapt to different directions of external flushing oil pipes, avoid the loosening or breakage of joints caused by rigid pipe connections, and ensure that nitrogen can smoothly enter the flushing oil pipes.

[0027] Flushing oil pipe connection joint 5: Flushing oil pipe connection joint 5 is the docking component between the device and the external flushing oil pipe. It ensures a tight fit at the joint and provides a reliable interface for nitrogen to enter the flushing oil pipe.

[0028] Mobile wheels 13: Mobile wheels 13 provide flexible mobility for the entire device, allowing it to be easily moved to different flushing pipeline operation sites. It is especially suitable for complex environments where large equipment pipelines are flushed, saving labor handling costs and improving operational convenience.

[0029] Furthermore, when using this device with the supplementary flushing oil recovery function, the first step is to prepare for the operation: the entire device is moved to the flushing pipeline operation site by means of the moving wheels 13 on the lower surface of the first fixed plate 1 and the second fixed plate 2. The design of the moving wheels 13 allows the device to flexibly adapt to different operation positions, and is especially suitable for the complex on-site environment of flushing large equipment pipelines, saving manpower handling costs. Among them, one end of the external flushing oil pipe is tightly connected to the flushing oil pipe connection joint 5 to ensure that the joint is sealed and leak-free. At the same time, the initial status of each valve is checked, and the high-pressure shut-off valve 4 is closed to prevent nitrogen from flowing into the flushing oil pipe before the pipeline is ready, and to avoid the flushing oil being disturbed in advance. When the outlet valve of the nitrogen tank 12 is opened, nitrogen is delivered to the input end of the adjustable gas pressure reducing valve 11 through the second hose 8. According to the diameter, length and viscosity of the flushing pipeline and the flushing oil, the adjustment knob of the adjustable gas pressure reducing valve 11 is rotated to set the appropriate output pressure and flow rate. This adjustment function can adapt to the purging requirements of pipelines of different specifications, and avoid damage to the pipeline due to excessive pressure or incomplete purging due to insufficient pressure. Nitrogen gas is depressurized by the adjustable gas pressure reducing valve 11 and flows into the input end of the one-way valve 9 through the third hose 10. The one-way conduction characteristic of the one-way valve 9 can prevent the flushing oil from flowing back into the nitrogen system due to pressure fluctuations during the subsequent purging process, avoid the nitrogen tank 12 and pressure reducing valve and other components from being contaminated by oil, and ensure the cleanliness of the nitrogen system. After the pipeline flushing is qualified, the outlet shut-off valve of the flushing pump is closed first to disconnect the flushing pump from the pipeline. Then, the high-pressure shut-off valve 4 is slowly opened. The clean nitrogen gas after pressure reduction passes through the first hose 3, the high-pressure shut-off valve 4, the fixed pipe 7, the spiral hose 6 and the flushing oil pipe connection joint 5 in sequence and enters the external flushing oil pipe. The flexibility of the spiral hose 6 can adapt to different directions of the flushing oil pipe and avoid the joint loosening or breakage caused by the rigid connection of the pipeline.

[0030] In this method, the flushing pump station is set up at a high position. High-pressure nitrogen creates a stable pressure difference in the pipeline, which pushes the flushing oil in the pipeline to flow along the pipeline to the flushing system tank. By controlling the nitrogen charging time, one or more purgings can be achieved to ensure that all the flushing oil in the pipeline is driven to the tank without any residue or waste. Compared with the traditional recovery method, nitrogen purging does not cause secondary pollution, and the cleanliness of the recovered flushing oil meets the standards and can be directly reused in the flushing system. The process involves closing the outlet valve of nitrogen tank 12, waiting for the nitrogen pressure in the pipeline to drop to atmospheric pressure, closing the high-pressure shut-off valve 4, disconnecting the flushing oil pipe connection joint 5 from the external flushing oil pipe, wiping the joint with a clean cloth to prevent residual oil contamination, and finally moving the device to its storage location using the casters 13 to complete the flushing oil recovery operation. In this system, by setting up flushing components, during the recovery of flushing oil in hydraulic lubrication pipelines, the various components work together. Nitrogen tank 12 provides the gas source, adjustable gas pressure reducing valve 11 precisely controls nitrogen pressure and flow, one-way valve 9 prevents oil backflow and contamination, high-pressure shut-off valve 4 controls nitrogen on / off, spiral hose 6 adapts to pipeline routing, and flushing oil pipe connection joint 5 achieves sealed connection. Combined with the high potential energy of the flushing pump station to drive the oil, this system achieves a comprehensive effect of adjustable nitrogen parameters, prevention of backflow and contamination, strong pipeline adaptability, and efficient recovery of flushing oil. Compared with traditional flushing oil recovery devices that are incomplete, wasteful, and polluting, this system can accurately adapt to the recovery needs of different pipeline specifications, ensuring that 100% of the flushing oil is recovered to the flushing system tank, with no residual waste or environmental pollutant emissions. This improves recovery efficiency by more than 30%, reduces flushing operation costs, and achieves the goal of efficient, economical, and pollution-free operation.
