The four groups of distributed vibrators have uniform and comprehensive vibrations, which can drive the two groups of inclined filter screens inside to vibrate, making it easier for metal debris to fall off without clogging the mesh. The structure is simple and the cost is low.

[0032] The first inclined filter screen plate 2 and the second inclined filter screen plate 3 of the filter box 1 are provided with openings on their outer surfaces, and the openings are designed to facilitate the vibration and extraction of metal debris;

[0033] The lower surface of the filter box 1 is fixed with a sleeve 10, and the inner surface of the sleeve 10 is filled with a compression spring 11 and a convex slider 12 to form an elastic support structure, which can be elastically supported on the ground. When vibrating, the vibration of the filter box can be increased, which is convenient for vibrating and extracting metal debris.

[0034] The first receiving shell 5 and the second receiving shell 6 are made of stainless steel to prevent rust;

[0035] The filter screen 56 adopts a fine filter screen and is made of stainless steel wire to avoid rust;

[0036] The first inclined filter screen plate 2 and the second inclined filter screen plate 3 are made of stainless steel wire mesh to avoid rust;

[0037] When in use, the cutting mixture is introduced from the feed inlet 7, and the metal debris is filtered through the first inclined filter screen plate 2, so that the metal debris can fall into the upper guide shell 4 and enter the first material receiving shell 5. The cutting fluid contained in the metal debris is filtered through the bottom filter screen 56 and refluxed to the bottom of the filter box 1. Similarly, after being filtered by the first inclined filter screen plate 2, the metal debris is filtered through the second inclined filter screen plate 3, and the metal debris is guided to the bottom of the guide shell 4, enters the second material receiving shell 6, and then the remaining cutting fluid is filtered out through the filter screen 56.
