[0002] In the field of machining, cutting fluid circulation filtration systems must meet the core requirements of high-purity fluid supply, dynamic flow stability, and intelligent operation and maintenance. Traditional pipeline layouts, due to their use of exposed pipes or underground trenches, face multiple constraints: First, pipelines and auxiliary equipment horizontally encroach on workshop floor space and lack three-dimensional planning, resulting in obstructed passageways, limited relocation of heavy equipment, and restrictions on production line layout adjustments, creating "space efficiency depressions"; Second, concealed structural designs force leak detection and maintenance operations to rely on large-scale disassembly, significantly increasing the complexity of operation and maintenance and the risk of production interruption. To address these issues, this application proposes a solution. Summary of the Invention

[0029] Example 1

[0030] See appendix Figures 1-4 The figure shows an overhead cutting fluid circulation pipe assembly for a filtration system, comprising a return fluid assembly. The return fluid assembly includes at least one set of gravity flow pipe 7, a booster pump 5, a booster pipe 8, a return fluid main pipe 1, and a return pipe 9. The inlet end of the gravity flow pipe 7 is connected to the machine base 3, and the outlet end is connected to the booster pump 5. The inlet end of the booster pipe 8 is connected to the booster pump 5, and the outlet end is connected to the inlet end of the return fluid main pipe 1. The return fluid main pipe 1 is overhead. The inlet end of the return fluid main pipe 9 is connected to the return fluid main pipe 1, and the outlet end is connected to the filtration system 4. By overhead setting the return fluid main pipe 1, the space above the machine base 3 is fully utilized, reducing the occupation of planar space.

[0031] In this embodiment, the return pipe 9 is set vertically or at an angle, with its inlet end higher than its outlet end.

[0032] In this embodiment, the return liquid assembly also includes a transfer tank 6. The inlet of the transfer tank 6 is connected to the gravity flow pipe 7, and the outlet is connected to the inlet of the booster pump 5. The transfer tank 6 is designed to facilitate the collection of dirty liquid and its unified delivery into the return liquid main pipe 1 via the booster pump 5.

[0033] In this embodiment, the gravity flow pipe 7 is inclined, with its inlet end higher than the outlet end connected to the transfer water tank 6, and the outlet end being the lowest point of the gravity flow pipe 7. This allows dirty liquid in the gravity flow pipe 7 that is far from the outlet end to flow smoothly to the outlet end.

[0034] In this embodiment, at least one inlet 12 is provided on the side of the transfer water tank 6, and a second switch valve 13 is provided on any inlet 12. The second switch valve 13 is used to control the flow of dirty liquid into the transfer water tank 6.

[0035] In this embodiment, a first switching valve 11 is provided between the liquid inlet end of the gravity flow pipe 7 and the liquid return port 10 of the machine 3. The first switching valve 11 is used to control the on / off of the liquid return of the machine 3.

[0036] In this embodiment, a third switch valve 14 is provided at the outlet of the booster pump 5. The third switch valve 14 is used to control the flow of dirty liquid from the transfer tank 6.

[0037] In this embodiment, a liquid supply pipe assembly is also included. The liquid supply pipe assembly includes a liquid supply pump 15, an ascending pipe 17, a main liquid supply pipe 2, and several liquid supply branch pipes 16 connected to the machine base 3. The inlet end of the ascending pipe 17 is connected to the liquid supply pump 15, and the outlet end is connected to the main liquid supply pipe 2. The main liquid supply pipe 2 is suspended overhead. The inlet end of any liquid supply branch pipe 16 is connected to the main liquid supply pipe 2, and the outlet end is connected to the liquid inlet of the machine base 3. After the liquid supply pump 15 delivers the clean liquid into the main liquid supply pipe 2 through the ascending pipe 17, it supplies liquid to the machine base 3 through the liquid supply branch pipes 16.

[0038] In this embodiment, the riser pipe 17 is arranged vertically or at an angle, with its inlet end lower than its outlet end.

[0039] In this embodiment, a plurality of support frames 18 are also included. One end of any support frame 18 is fixed to the ground, and the other end supports the return liquid pipe 1 and the supply liquid pipe 2, for mounting the return liquid pipe 1 and the supply liquid pipe 2 on the ground.

[0040] Example 2

[0041] When the machine is in operation, the machine 3 generates dirty liquid, which flows out from the return port 10 and flows into the gravity flow pipe 7 through the first switch valve 11. The gravity flow pipe 7 is inclined so that the dirty liquid flows to the lowest point, that is, to the transfer water tank 6.

[0042] The dirty liquid flows into the transfer tank 6 from the inlet 12 through the second switch valve 13. Under the action of the lift pump 5, the dirty liquid in the transfer tank 6 is extracted and enters the lift pipe 8 through the third switch valve 14. After being continuously pressurized, the dirty liquid in the lift pipe 8 flows into the return main pipe 1 and then flows into the dirty liquid tank of the filtration system 4 from the fall pipe 9 by its own weight to wait for filtration treatment.

[0043] The filtered liquid is stored in the liquid tank of the filtration system 4. Under the action of the liquid supply pump 15, the liquid is drawn into the riser pipe 17 and then enters the main liquid supply pipe 2. After flowing through the main liquid supply pipe 2, it flows into the machine 3 by its own weight through the liquid supply branch pipe 16.

[0044] When the machine is shut down for maintenance, close the second switch valve 13 and the third switch valve 14 to allow the liquid to be temporarily stored in the pipeline, which will facilitate the cleaning and maintenance of the transfer water tank 6.
