[0024] The filtering structure 2 includes a fixing frame 23 fixedly mounted on the left outer wall of the recovery box 11, a filter barrel 21 is fixedly mounted on the top of the fixing frame 23, a recovery transmission pipe 22 is fixedly mounted on the left side of the outer wall of the filter barrel 21, a transmission pipe 25 is fixedly mounted on the outer wall of the bottom of the filter barrel 21, and a switch valve 26 is fixedly mounted on the outer wall of the transmission pipe 25.

[0025] It should be noted that, in this embodiment, the discarded micro-etching liquid is transferred to the interior of the filter barrel 21 through the recovery transmission pipe 22, and then the micro-etching liquid is filtered for impurities therein through the filter barrel 21. Then, the micro-etching liquid and the filtered micro-etching liquid are transferred to the interior of the recovery box 11 through the transmission pipe 25, and the micro-etching liquid is allowed to enter the stirring tank 12 for stirring to prevent the recyclable substances therein from settling easily. Then, the micro-etching liquid is allowed to enter the anode electrolysis needle 1311 and the cathode electrolysis needle 1321 at the bottom of the No. 1 electrolysis rack 131 and the No. 2 electrolysis rack 132 through the connecting tank 14 for electrolytic processing. After processing, it can be recycled.

The bottom of the inner cavity of the filter barrel 21 and located larger than the transmission pipe 25 is fixedly installed with an activated carbon plate 215.

[0027] It should be noted that, in this embodiment, the micro-etching liquid is transferred to the interior of the filter barrel 21 through the recovery transmission pipe 22, and then the No. 2 drive motor 24 is started, and the outer wall of the top of the No. 2 drive motor 24 is used to drive the No. 2 transmission rod 241 to rotate slowly, and the No. 2 transmission rod 241 is stuck in the outer wall of the bottom projection of the transmission protrusion 214 through the top groove, so that it drives the transmission protrusion 214 to rotate slowly, and when the transmission protrusion 214 rotates, it drives the rotating block 212 to rotate, and then the filter frame 213 connected to the bottom of the outer wall of the rotating block 212 rotates, so that the filter frame 2 13 drives 2131 to rotate, and the rotation of the impurity filter 2131 can prevent the impurities in the micro-etching liquid from being blocked on the outer wall of the impurity filter 2131 when filtering the micro-etching liquid, and then the filtered micro-etching liquid is filtered through the activated carbon plate 215 so that it is transmitted to the interior of the recovery box 11 through the transmission pipe 25. The filter frame 213 is taken away from the inner cavity of the filter barrel 21 by rotating the sealing cover 211 to push the rubber disc 2132, and the micro-etching liquid impurities remaining on the inner wall of the filter barrel 21 are taken away from the inner cavity of the filter barrel 21, thereby facilitating the cleaning of the inner cavity of the filter barrel 21.

[0028] like Figure 1 、 Figure 2 As shown, one end of the bottom transmission of the No. 1 drive motor 122 is connected to the No. 1 transmission rod 1221, and the outer wall of the bottom of the No. 1 transmission rod 1221 and the inner side of the stirring tank 12 are fixedly sleeved with a stirring blade 1222, and the outer wall on the left side of the electrolytic cell 13 is fixedly installed with a sensor 135, and the top of the sensor 135 is fixedly installed with a transmission line 134, and one end of the transmission line 134 is fixedly installed with an alarm light 133, and a connecting groove 14 is provided at the bottom of the inner side of the recycling box 11 and on the right side of the bottom of the stirring tank 12.

[0029] It should be noted that, in this embodiment, the filtered micro-etching liquid is transmitted to the inner side of the stirring tank 12 through the transmission tube 25, and then the No. 1 driving motor 122 is started, and the No. 1 transmission rod 1221 at the bottom of the No. 1 driving motor 122 drives the stirring blade 1222 to rotate, so that the stirring blade 1222 stirs the micro-etching liquid, so that the micro-etching liquid cannot be precipitated, and then the micro-etching liquid is introduced into the inner side of the electrolytic tank 13 through the connecting groove 14 for electrolysis. During the electrolysis, over-temperature, over-current and over-voltage are sensed by the sensor 135. If the sensing is incorrect, the signal is transmitted to the alarm light 133 via the transmission line 134, and an alarm is issued through the alarm light 133.

[0030] The working principle of the utility model is as follows: the filtered micro-etching liquid is transferred to the inner side of the stirring tank 12 through the transmission tube 25, and then the No. 1 driving motor 122 is started, and the No. 1 transmission rod 1221 at the bottom of the No. 1 driving motor 122 drives the stirring blade 1222 to rotate, so that the stirring blade 1222 stirs the micro-etching liquid, making it unable to precipitate.

[0031] The micro-etching liquid is transferred to the interior of the filter barrel 21 through the recycling transfer pipe 22, and then the No. 2 driving motor 24 is started, and the outer wall of the top of the No. 2 driving motor 24 is used to drive the No. 2 transmission rod 241 to rotate slowly, and the No. 2 transmission rod 241 is stuck in the outer wall of the bottom protrusion of the transmission protrusion 214 through the top groove, so that it drives the transmission protrusion 214 to rotate slowly. When the transmission protrusion 214 rotates, it drives the rotating block 212 to rotate, and then the filter frame 213 connected to the bottom of the outer wall of the rotating block 212 rotates, so that the filter frame 213 drives 213 1 rotates, and the rotation of the impurity filter 2131 can prevent the impurities in the micro-etching liquid from being blocked on the outer wall of the impurity filter 2131 when filtering the micro-etching liquid, and then the filtered micro-etching liquid is filtered through the activated carbon plate 215 so that it is transmitted to the interior of the recovery box 11 through the transmission pipe 25. The sealing cover 211 is rotated to remove the filter frame 213 from the inner cavity of the filter barrel 21 and push the rubber disc 2132 to remove the micro-etching liquid impurities remaining on the inner wall of the filter barrel 21 from the inner cavity of the filter barrel 21, thereby facilitating the cleaning of the inner cavity of the filter barrel 21.

[0032] Then, the micro-etching liquid is allowed to enter the anode electrolysis needle 1311 and the cathode electrolysis needle 1321 at the bottom of the No. 1 electrolysis rack 131 and the No. 2 electrolysis rack 132 through the connection slot 14 for electrolytic processing. During the electrolysis, the sensor 135 senses over-temperature, over-current, and over-voltage. If the sensing is incorrect, the signal is transmitted to the alarm light 133 through the transmission line 134, and an alarm is sounded through the alarm light 133. After processing, it can be recycled.
