Description

Technical Field

[0001] This utility model relates to the field of hydraulic pipeline flushing technology, specifically a high-efficiency circulating flushing device for hydraulic pipelines. Background Technology

[0002] Residual contaminants within hydraulic pipelines are a major cause of equipment malfunctions in hydraulic systems. After hydraulic pipeline construction is completed, the pipelines must be flushed to remove particles and other impurities from the pipes and hydraulic oil. The hydraulic system can only be put into use after the oil has passed laboratory testing.

[0003] Traditional hydraulic pipeline circulation flushing devices use hydraulic pump sets to circulate and flush the pipelines, and frequently replace filter elements to filter out impurities in the pipelines.

[0004] However, in actual use, the traditional hydraulic pipeline circulating flushing device mainly uses a hydraulic pump set to circulate and flush the pipeline, filtering out impurities and contaminants by frequently replacing the filter element. However, due to the uneven fluid flow inside the hydraulic system, the flushing time is often too long, the flushing efficiency is low, and impurities cannot be completely removed, resulting in a large amount of contaminants remaining in the pipeline, making it difficult to complete the effective cleaning work in a short time. In view of this, we propose a high-efficiency hydraulic pipeline circulating flushing device. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency circulating flushing device for hydraulic pipelines to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency circulating flushing device for hydraulic pipelines, comprising a frame, a fixing bracket fixedly connected to the inner wall of the frame, and a flushing assembly provided on the inner wall of the frame, the flushing assembly comprising:

[0007] A water pump, wherein a three-way valve is fixedly connected to the water inlet end of the water pump, and a three-way valve is fixedly connected to the water outlet pipe of the water pump.

[0008] A flexible outer tube, wherein a rubber ring is fixedly connected to the inner wall of the flexible outer tube, and an inner convex ring is fixedly connected to the outer wall of the flexible outer tube;

[0009] A flexible inner tube, wherein a connecting pipe is provided on the inner wall of the flexible inner tube, and an outer protruding ring is fixedly connected to the inner wall of the flexible inner tube.

[0010] Preferably, a pull rope is fixedly connected to the outer wall of the flexible outer tube, and the pull rope is connected to the two-way valve. By pulling the pull rope, the flexible outer tube and the flexible inner tube are reset.

[0011] Preferably, the right end of the three-way valve is fixedly connected to a water inlet pipe, and the water pump is fixedly connected to the inner wall of the fixed frame. Water can be filled into the flexible inner pipe or hydraulic pipeline through the water inlet pipe.

[0012] Preferably, the number of inner convex rings, rubber rings, and connecting pipes is arranged in several groups, and the several groups of inner convex rings, rubber rings, and connecting pipes are respectively arranged on the end faces of the flexible outer tube and the flexible inner tube.

[0013] Preferably, the flexible outer tube is fixedly connected to the left end face of the three-way valve, and the flexible inner tube is fixedly connected to the inner wall of the flexible outer tube.

[0014] Preferably, a brush is fixedly connected to the inner wall of the flexible outer tube, and a water outlet is fixedly connected to the inner wall of the flexible outer tube.

[0015] Preferably, the number of brushes and water outlets is set in several groups, and the several groups of brushes and water outlets are arranged at equal intervals on the inner wall of the flexible outer tube.

[0016] Compared with the prior art, this utility model provides a high-efficiency circulating flushing device for hydraulic pipelines, which has the following beneficial effects:

[0017] 1. This high-efficiency circulating flushing device for hydraulic pipelines, through its flushing components, uses rubber rings to scrape away stubborn dirt, particles, and deposits adhering to the pipe wall, reducing the flushing time, improving impurity removal capacity, and reducing reliance on filter elements. The flexible outer tube can adapt to hydraulic pipelines of different specifications and can operate in pipelines of different shapes and bends, making it suitable for various complex pipelines, not just straight pipe cleaning, thus improving applicability and flexibility. The inner convex ring squeezes the outer convex ring, which in turn squeezes the rubber ring, applying additional pressure to the rubber ring and enhancing the scraping force of the rubber ring on the pipe wall, thereby improving the removal effect of impurities and removing tight oil stains, deposits, and stubborn particulate contaminants.

[0018] 2. This high-efficiency circulating flushing device for hydraulic pipelines uses brushes and water outlets. Water flows through the outlets to wet the impurities on the inner wall of the hydraulic pipelines, softening them and making them easier to brush off. The hydraulic pipelines are pulled outwards, and the brushes rub against the inner wall of the hydraulic pipelines, removing the contaminants attached to the pipe walls and improving cleaning efficiency.

[0025] like Figures 1-5 As shown, this utility model provides a technical solution: a hydraulic pipeline high-efficiency circulating flushing device, including a frame 1, a fixing frame 2 fixedly connected to the inner wall of the frame 1, and a flushing assembly 3 provided on the inner wall of the frame 1. The flushing assembly 3 includes a water pump 301, a three-way valve 1 302, a water inlet pipe 303, a three-way valve 2 304, a flexible outer pipe 305, a rubber ring 306, an inner convex ring 307, a flexible inner pipe 308, a connecting pipe 309, and an outer convex ring 310.

[0026] In one embodiment of this utility model, a three-way valve 302 is fixedly connected to the water inlet end of the water pump 301, and a water inlet pipe 303 is fixedly connected to the right end of the three-way valve 302. The water pump 301 is fixedly connected to the inner wall of the fixing frame 2. Water can be filled into the flexible inner pipe 308 or the hydraulic pipeline through the water inlet pipe 303. A three-way valve 304 is fixedly connected to the water outlet pipe of the water pump 301.

[0027] A rubber ring 306 is fixedly connected to the inner wall of the flexible outer tube 305, an inner convex ring 307 is fixedly connected to the outer wall of the flexible outer tube 305, and a pull rope 6 is fixedly connected to the outer wall of the flexible outer tube 305. The pull rope 6 is sleeved with the three-way valve 304. By pulling the pull rope 6, the flexible outer tube 305 and the flexible inner tube 308 are reset.

[0028] The inner wall of the flexible inner tube 308 is provided with a connecting pipe 309. An outer convex ring 310 is fixedly connected to the inner wall of the flexible inner tube 308. The number of inner convex rings 307, rubber rings 306 and connecting pipes 309 are arranged in several groups. The several groups of inner convex rings 307, rubber rings 306 and connecting pipes 309 are respectively arranged on the end face of the flexible outer tube 305 and the flexible inner tube 308. The flexible outer tube 305 is fixedly connected to the left end face of the three-way valve 304. The flexible inner tube 308 is fixedly connected to the inner wall of the flexible outer tube 305.

[0029] The hydraulic line is fitted onto the outer wall of the flexible outer tube 305. Then, the water pump 301 draws water into the flexible inner tube 308. The water pushes the flexible outer tube 305 and the flexible inner tube 308 to rotate outwards away from the water pump 301, causing the outer wall of the flexible outer tube 305 to fit against the inner wall of the hydraulic line. The rubber ring 306 rotates outwards, contacting the inner wall of the hydraulic line. Once the flexible outer tube 305 is fully against the inner wall of the hydraulic line, the hydraulic line is pulled outwards, disengaging the flexible outer tube 305 from the hydraulic line. The rubber ring 306 then releases the hydraulic line. Impurities on the inner wall are scraped off, and then the two ends of the hydraulic pipeline are fixed to the bottom of the three-way valve 302 and the bottom of the three-way valve 304, respectively. The hydraulic pipeline is then circulated and flushed by starting the water pump 301. Stubborn dirt, particles and deposits attached to the pipe wall are scraped off by the rubber ring 306, which reduces the flushing time, improves the impurity removal capacity, and reduces the dependence on the filter element. The flexible outer tube 305 can adapt to hydraulic pipelines of different specifications and can operate in pipelines of different shapes and bends. It is suitable for various complex pipelines, not just straight pipe cleaning, which improves applicability and flexibility.

[0030] Before pulling the hydraulic line outward, the flexible outer tube 305 is pulled outward by the pull rope 6. When encountering greater resistance, the inner convex ring 307 comes into contact with the outer convex ring 310. The inner convex ring 307 squeezes the outer convex ring 310, which in turn squeezes the rubber ring 306, applying additional pressure to the rubber ring 306. This enhances the scraping force of the rubber ring 306 on the pipe wall, improves the removal effect of impurities, and removes tight oil stains, deposits, and stubborn particulate contaminants.

[0031] In addition, a brush 4 is fixedly connected to the inner wall of the flexible outer tube 305, and a water outlet 5 is fixedly connected to the inner wall of the flexible outer tube 305. Several sets of brushes 4 and water outlets 5 are arranged at equal intervals on the inner wall of the flexible outer tube 305. When the flexible inner tube 308 is flipped outward away from the water pump 301, the brush 4 is in contact with the inner wall of the hydraulic pipeline. Water is used to wet the impurities on the inner wall of the hydraulic pipeline through the water outlet 5, making them soft and easier to be brushed off. The hydraulic pipeline is pulled outward, and the brush 4 rubs against the inner wall of the hydraulic pipeline to remove the contaminants attached to the pipe wall, thereby improving the cleaning efficiency.

[0032] In this invention, during use, the hydraulic pipeline is fitted onto the outer wall of the flexible outer tube 305. The water pump 301 draws water into the flexible inner tube 308. The water pushes the flexible outer tube 305 and the flexible inner tube 308 to flip outwards in a direction away from the water pump 301. The rubber ring 306 flips outwards and contacts the inner wall of the hydraulic pipeline, pulling the hydraulic pipeline outwards. The rubber ring 306 scrapes off impurities from the inner wall of the hydraulic pipeline. Then, the two ends of the hydraulic pipeline are fixed to the bottom of the three-way valve 1 302 and the bottom of the three-way valve 2 304, respectively. The hydraulic pipeline is circulated and flushed by starting the water pump 301. The flexible outer tube 305 is pulled outwards by the pull rope 6. The inner convex ring 307 contacts the outer convex ring 310. The inner convex ring 307 squeezes the outer convex ring 310, which in turn squeezes the rubber ring 306, applying additional pressure to the rubber ring 306 and improving the removal effect of impurities.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
