DETAILED DESCRIPTION

[0049] 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.

[0050] Example: As attached Figures 1 to 14 As shown, this embodiment provides a pipeline degreasing device, including a cleaning device 1 for cleaning pipelines, a conveying device 2 for transporting pipelines to the cleaning device 1, and a storage device 3 for providing cleaning fluid to the cleaning device 1 and recovering waste fluid. The pipeline is fed into the cleaning device 1 via the conveying device 2, and then injected into the cleaning device 1 by the storage device 3 for reaction cleaning. After the pipeline is cleaned, the waste fluid is discharged through the storage device 3, and the cleaned pipeline is pulled out via the conveying device 2, completing the pipeline cleaning process. This equipment replaces manual cleaning, requires only one operator, and has excellent characteristics such as simple operation, safety, environmental friendliness, economical and energy-saving operation, and outstanding degreasing and degreasing performance.

[0051] As attached Figures 2 to 6 As shown, the cleaning device 1 includes a mounting frame 4 and a cleaning chamber 5 mounted on the mounting frame 4. The cleaning chamber 5 has an inlet / outlet 6 at at least one end for pipe entry, and an openable / closable door 7 at the inlet / outlet 6. The cleaning chamber 5 has an inlet 8 and an outlet 9 near both ends, respectively. The hollow cleaning chamber 5 allows pipes to enter through the inlet / outlet 6, cleaning agent to enter through the inlet 8, and waste liquid to be discharged through the outlet 9. The structure is simple, reliable, and easy to manufacture.

[0052] In addition, multiple viewing mirrors can be installed on the cleaning chamber 5 to facilitate observation of the cleaning process inside the cleaning chamber 5. At the same time, two one-way valves are installed on the cleaning chamber 5. One one-way valve allows gas to enter only, and the other one-way valve allows gas to exit only. The one-way valve for exiting gas is connected to the gas treatment device through the exhaust pipe to dissipate the gas generated by the internal reaction.

[0053] As attached Figures 2 to 6 As shown, the cleaning device 1 also includes a high-pressure jet assembly 10. The high-pressure jet assembly 10 divides the interior of the cleaning chamber 5 into an inlet chamber 11 connected to the inlet 8 and a cleaning chamber 12 for storing pipes. The high-pressure jet assembly 10 includes a fixed outer ring 13 connected to the inner wall of the cleaning chamber 5 and a perforated plate 14 installed at the center of the fixed outer ring 13. The two can be connected by bolts or fixed by welding. After the washing liquid enters the inlet chamber 11 of the cleaning chamber 5, it is sprayed into the cleaning chamber 12 through the perforated plate 14 to flush the pipes, thereby improving the cleaning efficiency and effect of the pipes.

[0054] As attached Figures 2 to 6 As shown, the cleaning device 1 also includes a cylinder 15. A fixed sleeve 16 is welded to the outer periphery of the cleaning chamber 5. A rotating shaft 17 is provided at each end of the fixed sleeve 16, and multiple reinforcing ribs 18 are provided between each rotating shaft 17 and the fixed sleeve 16. The rotating shaft 17 is welded to the fixed sleeve 16, and then the fixed sleeve 16 is welded to the cleaning chamber 5, making processing and assembly more convenient. A bearing seat 19 is provided on each side of the mounting frame 4 corresponding to the cleaning chamber 5. The rotating shaft 17 is rotatably engaged with the corresponding bearing seat 19. The fixed end of the cylinder 15 is hinged to the mounting frame 4, and the movable end of the cylinder 15 is hinged to the part of the cleaning chamber 5 near the end. When the cylinder 15 extends or retracts, it causes the cleaning chamber 5 to swing. When the cylinder 15 extends or retracts, it can cause the cleaning chamber 5 to rotate around the rotating shaft 17, causing the internal liquid to slosh, so that the cleaning liquid and the stains on the pipe can react fully, which can further improve the cleaning effect of the pipe.

[0055] As attached Figures 2 to 6 As shown, the inlet and outlet 6 of the cleaning chamber 5 are welded with connecting flanges 20. The chamber door 7 is hinged to the connecting flanges 20.

The chamber door 7 can be closed by engaging the swivel bolts 21 into the second groove 23 on the chamber door 7 and tightening the locking nuts 24. The chamber door 7 can be opened by loosening the locking nuts 24 and loosening the swivel bolts 21 out of the second groove 23. The opening and closing operation of the chamber door 7 is very convenient.

More specifically, the annular support plate 30 can be made of silicone material. The inner circular surface of the annular support plate 30 protrudes from the inner circular surface of the annular connecting plate 28 to support the pipe. The overall shape of the inlet basket 26 is adapted to the cleaning chamber 5. The structure of multiple connecting rods 29 and annular connecting plates 28 results in less obstruction and better cleaning effect. At the same time, the elastic annular support plate 30 supports the pipe and is less likely to scratch the pipe, thus protecting the pipe.

[0057] As attached Figures 7 to 12 As shown, a wheel frame 31 is provided on each side of the annular connecting plate 28.

The drive rod 41 is meshed with the driving sprocket 38 and the driven sprocket 39. One end of the drive rod 41 is hinged to one link of the chain 40, specifically, a hinge seat is welded to this link, and one end of the drive rod 41 is hinged to this hinge seat. The other end of the drive rod 41 is equipped with a linkage plate 42, which can be L-shaped. The linkage plate 42 and the drive rod 41 form a drive groove 43 for engaging with the annular connecting plate 28 located at the end of the inlet basket 26. The chain 40 transmission structure has a strong load-bearing capacity and no elastic slippage or slippage.
