DETAILED DESCRIPTION

[0014] The utility model provides a design of a device for recycling and reusing developer of a printed circuit board.

[0015] In order to have a further understanding and recognition of the purpose, features and effects of the utility model, the following is a detailed description of the implementation mode and drawings:

[0016] See also Figures 1 to 3 As shown, the utility model provides a device for recycling and treating developer solution for printed circuit boards, comprising:

[0018] See also Figure 4 As shown, it shows an enlarged cross-sectional state of a centrifugal membrane 711, and a plurality of tiny holes 7111 are provided on the centrifugal membrane 711. Under the centrifugal effect, large impurities 81 are taken away from the holes 7111, and small developer particles 91 are filtered out through the holes 7111 of the centrifugal membrane 711, thereby improving the recovery rate of the developer and preventing large impurities 81 from adhering to and blocking the holes 7111.
