[0043] A plurality of legs 101 are fixedly mounted on the bottom of the cylinder 1 in a circular array.

[0044] Working principle: The entire copper powder filter, external power supply and control switch are used for power supply and electrical control;

[0045] When in use, the structure inside the cylinder 1 is as follows Figure 1 As shown, the electric push rod 18 is in a retracted state, so that the movable cover 3 is in a lower position, so that the rubber gasket is pressed against the top surface of the disc 2 to form a seal, and the rubber ring on the receiving cover 8 is pressed against the bottom surface of the disc 2 to form a seal;

[0046] The sewage generated by PCB board processing enters through the water inlet pipe 5, then passes through the rubber bellows 4, the interface 301, and the movable cover 3 in sequence, and is discharged from the bottom of the movable cover 3, and then filtered through the filter plate 202. The filtered sewage enters the drainage cover 9 and is then discharged through the drainage pipe 10. The drainage pipe 10 can be connected to an external water pipe to discharge the sewage into other sewage treatment equipment;

[0047] In the above process, the copper powder in the water is filtered through the filter screen plate 202 and is intercepted to the top surface of the filter screen plate 202;

[0048] After filtering for a period of time, the filter screen plate 202 needs to be maintained, and the copper powder filtered from the top surface of the filter screen plate 202 is cleaned and removed; the specific operation is as follows: the water inlet pipe 5 stops discharging sewage, and then the electric push rod 18 is extended, and the movable cover 3 is driven upward through the connecting strip 14. When it moves upward, the rubber bellows 4 is squeezed upward to shrink the rubber bellows 4. The design of the rubber bellows 4 will not affect the up and down movement of the movable cover 3, and the movable cover 3 is always connected to the water inlet pipe 5. After the movable cover 3 moves upward, the structure inside the cylinder 1 is as shown in FIG. Figure 2 As shown, the top of the filter screen plate 202 is unblocked, and then the first motor 13 drives the connecting rod 16 to rotate, and the first bevel gear 12 and the second bevel gear 17 are meshed and driven to drive the rotating shaft 6 to rotate, so that the strip brush 7 brushes the top of the disc 2, and the bristles of the strip brush 7 pass through the filter screen plate 202, driving the copper powder to move toward the lower material trough 201. After the copper powder passes through the lower material trough 201, it is discharged and discharged into the receiving cover 8 for collection;

[0049] After cleaning, the first motor 13 is turned off, and then the electric push rod 18 is retracted to press the sealing gasket 302 against the top surface of the disc 2 again;

[0050] After the material receiving hood 8 collects the copper powder, the material receiving hood 8 is driven downward by the lifting mechanism 15 to make the material receiving hood 8 leave the bottom of the cylinder 1; the specific operation is as follows: the second motor 1502 drives the screw 1503 to rotate, the screw 1503 and the threaded hole are screwed, and the movable seat 1504 and the guide groove 103 are coordinated to realize the vertical drive of the movable seat 1504. When the movable seat 1504 moves vertically, it drives the material receiving hood 8 to move, so that the material receiving hood 8 can be moved to the bottom of the cylinder 1 and leave the cylinder 1, and then the insertion rod 20 can be manually pulled to pull the insertion rod 20 out of the positioning insertion hole 1101, and then the material receiving hood 8 is pulled to pull the insertion block 11 out of the slot, canceling the positioning, and then the material receiving hood 8 can be pulled to be taken out from the bottom of the cylinder 1. After being taken out, the material in the material receiving hood 8 can be dumped and discharged;

[0051] After dumping the material, the material receiving cover 8 is inserted into the lower part of the cylinder 1 again, and the insertion rod 20 is pulled to make the bottom end of the insertion rod 20 enter the guide sleeve 19, and then the insertion block 11 is inserted into the slot, and the insertion rod 20 is released. Through the elastic force of the spring 21, the insertion rod 20 is inserted into the positioning socket 1101 to achieve positioning, and the installation of the material receiving cover 8 is completed. Then, the lifting mechanism 15 is driven to make the rubber ring on the material receiving cover 8 contact with the bottom surface of the disc 2, and the use is completed.

[0052] It should be noted that both the first motor 13 and the second motor 1502 are servo motors; each time the strip brush 7 cleans, the first motor 13 drives the strip brush 7 to rotate an integer number of circles, and resets it to its original position after each cleaning.
