Abstract
Description
Technical Field
[0001] This utility model relates to the field of hydraulic oil pipeline cleaning technology, specifically, to a flushing device for hydraulic oil pipelines. Background Technology
[0002] Hydraulic oil lines are the "blood vessels" of a hydraulic system, responsible for transporting hydraulic oil from the tank to various hydraulic components, such as hydraulic pumps, cylinders, and valves, to achieve energy transfer and control. They are typically composed of steel pipes, hoses, and fittings, and must possess excellent sealing, pressure resistance, and corrosion resistance to ensure stable system operation. After installation or maintenance of a hydraulic system, welding slag, rust, dust, and other impurities may remain inside the lines. If these impurities are not cleaned, they will flow with the hydraulic oil, wearing down hydraulic components, leading to system malfunctions, leaks, and even safety accidents. Therefore, flushing hydraulic oil lines is crucial.
[0003] CN218797892U discloses a flushing device for hydraulic oil pipelines, belonging to the field of pipeline flushing. It includes a water tank, a pump, a motor, a water pipeline, and a return water pipeline. A filter structure is installed on the side of the water tank, and one end of the return water pipeline is connected to the filter structure. The filter structure includes a solid filter component and an oil filter component, with the solid filter component located above the oil filter component. This flushing device is suitable for oil pipelines of different diameters. It has a simple structure and is easy to operate, introducing a new process for flushing hydraulic oil pipelines, improving the efficiency and quality of pipeline flushing, reducing personnel input and labor, accelerating construction progress, saving construction costs, and ensuring the quality of hydraulic oil pipeline flushing.
[0004] The filter structure (solid filter component and oil filter component) in the above-mentioned flushing device for hydraulic oil pipelines is a fixed design. Impurities are easily attached to the filter screen, resulting in a decrease in flow efficiency. Frequent shutdowns and manual cleaning are required, which affects the flushing efficiency.

A sleeve assembly 3 is provided in the middle of the circulation pipeline 2. The sleeve assembly 3 includes a sleeve 31 assembled in the middle of the circulation pipeline 2. A filter assembly 4 for filtering the circulating medium is provided inside the sleeve 31. The filter assembly 4 includes a filter cartridge 41 that can be spirally sealed with the sleeve 31. A cleaning assembly 5 is also provided inside the sleeve 31 to rotate and clean the filter assembly 4 to prevent impurities from adhering. This design solves the core problems of easy clogging and inconvenient maintenance of traditional flushing devices by using a dynamic cleaning mechanism and modular filtration design, thereby improving the degree of automation and ease of operation. It is especially suitable for pipeline flushing scenarios of high-frequency or high-flow hydraulic systems.
[0020] The kit 3 also includes an inlet pipe 32, which is fixedly connected to the inner and outer sides of the sleeve 31. The kit 3 also includes a pump body 321, which is fixedly installed on the upper part of the inlet pipe 32.
[0021] The kit component 3 also includes slots 311, which are provided on both sides of the sleeve 31. The sleeve 31 is engaged with the middle of the circulation pipeline 2 through the slots 311.
[0022] The assembly 3 also includes a threaded groove 312 and an annular groove 313, which are formed on the inner wall of the sleeve 31.
[0023] The filter assembly 4 also includes a filter screen 411, which is fixedly connected to the front of the filter cartridge 41.
[0024] The filter assembly 4 also includes a threaded ring 412 and a sealing ring 413, which are fixedly connected to the outside of the filter cartridge 41. The threaded ring 412, the sealing ring 413, the threaded groove 312, and the annular groove 313 are matched.
[0025] The cleaning assembly 5 includes a mounting base 51, which is fixedly connected to the outside of the sleeve 31. The cleaning assembly 5 also includes a forward and reverse motor 511, which is fixedly installed inside the mounting base 51. The output end of the forward and reverse motor 511 is fixedly connected to a rotating shaft 52, and a gear plate 521 is fixedly connected to the outside of the rotating shaft 52.
[0026] The cleaning assembly 5 also includes a ring seat 53, which is rotatably connected to the inner side of the sleeve 31. The outer side of the ring seat 53 has a ring-shaped toothed groove group 531, which is in contact with the toothed disc 521 and is meshed and rotatably connected. The cleaning assembly 5 also includes a cleaning plate 54, which is fixedly connected to the inner side of the ring seat 53 in a ring shape and is in contact with the filter screen 411.
[0027] The working principle and usage process of this utility model are as follows: The staff first took out the sleeve 31 and aligned the slots 311 on both sides of the sleeve 31 with the circulation pipe 2 and inserted it. At this time, the sleeve 31 was fixedly installed in the middle of the circulation pipe 2. Then, the inlet pipe 32 was connected to the external liquid injection mechanism. The pump body 321 was used to draw the cleaning fluid in the liquid injection mechanism into the sleeve 31 through the inlet pipe 32. Since the inlet pipe 32 is designed in a Z shape inside the sleeve 31, the cleaning fluid in the inlet pipe 32 will flow out towards the filter component 4 and complete the circulation cleaning in the circulation pipe 2, the hydraulic oil pipe body 1 and the sleeve 31. In particular, during the cyclic cleaning process, some impurities will adhere to the filter screen 411. At this time, the forward and reverse motor 511 can be started to drive the rotating shaft 52 and the toothed disc 521 to rotate. Under the meshing and rotation of the toothed disc 521 and the toothed groove group 531, the ring seat 53 located inside the toothed groove group 531 will rotate in the sleeve 31 and complete the light brushing of the filter screen 411 through the cleaning brush plate 54. This design can ensure the smooth flow of cleaning liquid at the filter screen 411. Specifically, after the hydraulic oil pipeline body 1 has been flushed, the sleeve 31 can be removed from the circulation pipeline 2. At this time, the filter cartridge 41 can be twisted to detach the filter cartridge 41 from the inside of the sleeve 31. Then, the accumulated impurities inside the sleeve 31 and the filter cartridge 41 can be cleaned.
[0028] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
