A discharge port 18 located at the upper end of the fine filter 3 is arranged on the side wall of the processing frame 1, and the discharge port 18 is externally connected to a discharge curved pipe 21.

[0037] The sedimentation ball assembly is composed of a pair of semi-hollow spherical upper sedimentation hemisphere 2 and lower sedimentation hemisphere 4 sealed connection components which are symmetrical up and down. A coarse filter screen 17 is arranged in the hollow inner cavity of the sedimentation ball assembly. A buffer tube 10 extending to the lower end of the coarse filter screen 17 is vertically inserted into the upper end of the sedimentation ball assembly. The buffer tube 10 is externally connected to the feed pipe 14. The outer walls of the upper sedimentation hemisphere 2 and the lower sedimentation hemisphere 4 are provided with a plurality of groups of arc-shaped guide grooves 8 which are recessed inward and are distributed in a circular array. The guide grooves 8 extend along the arc outer walls of the upper sedimentation hemisphere 2 and the lower sedimentation hemisphere 4 to the lower end of the fine filter screen 3.

[0038] The sedimentation ball assembly is used to buffer and precipitate the feed cutting fluid mixture, thereby greatly filtering out large particles. The cutting fluid is caused to overflow downward along the guide groove 8 on the outer wall of the spherical arc through overflow, thereby achieving the goal of fully spreading the cutting fluid while reducing the impact, allowing the cutting fluid mixed raw materials to overflow for the second time on the fine filter screen 3 to filter out small particles of impurities.

[0039] The rotating sedimentation assembly includes a rotating frame 19 and a roller 22. The roller 22 is rotatably installed on the rotating frame 19 and driven by a motor. Four groups of magnetic sheets 23 distributed in a circular array are arranged on the outer wall of the roller 22.

[0053] By setting the cooperation of the mounting nut 9 and the sleeve 28, the extrusion-type fixed installation of the mounting arc plate 7 is realized, thereby achieving the purpose of limiting the installation height of the fine filter 3. By setting the guide ring 27, the cutting fluid can accurately fall on the lower end of the fine filter 3 along the guide groove 8, and at the same time limit the overflow height to prevent the cutting fluid at the lower end of the fine filter 3 from overflowing in the opposite direction along the guide groove 8.
