(1) the fixed seat 12 is fixed on the filtering base 1 through a fixing screw 15.

(2) The end of the pressing plate 13 is clamped into the gap formed between the second limit plate 8 and the filtering base 1, the other end of the pressing plate 13 is clamped into the gap formed between the outer convex plate 16 and the filtering base 1, the second limit plate 8 is screwed with the first bolt 14, the end of the first bolt 14 is tightly pressed on the pressing plate 13, the outer convex plate 16 is screwed with the second bolt 17, and the second bolt 17 is tightly pressed on the pressing plate 13.

(3) Pack into the foam in first limiting plate 7, sleeve pipe 6 and the second limiting plate 8 of structure as an organic whole, play the effect of shutoff, avoid impurity to get into in the sleeve pipe 6 in the later stage transportation.

g. Conveying the installed filter base 1: the third bolt 30 on the slide rail 18 is unscrewed, and the installed filter base 1 is removed from the support bar 29 and placed on the conveyor belt 31.

h. And (3) filling a filter screen 2: the other end of the conveying belt 31 is used for collecting the installed filter base 1 in a centralized manner, then the foam is taken out, and then the filter screen 2 is arranged in the first limiting plate 7, the sleeve 6 and the second limiting plate 8 which are of an integrated structure. The operation space for loading the filter net 2 can be in an independent state without being influenced by the operation space of the machine tool 21, and the phenomenon that the filter net 2 is damaged in the loading process can be reduced.

The above is only a specific embodiment of the present invention, but the technical features of the present invention are not limited thereto. Any simple changes, equivalent substitutions or modifications made based on the present invention to solve the same technical problems and achieve the same technical effects are within the scope of the present invention.
