[0027] Please refer to Figure 2 In the embodiment, branch outlet pipe 71 can be connected to secondary filter box 54, and branch outlet pipe 71 can enter main outlet pipe 72.Wastewater in secondary filter box 54 is filtered clean, filtered water in secondary filter box 54 is collected through branch outlet pipe 71, and flows into main outlet pipe 72, and is sent to front end through a waterway, so that the manufacturing cost of recovery purification device for circuit board wastewater treatment can be effectively reduced without affecting pipe blockage.

[0028] Please refer to Figure 3 In the embodiment, four water inlet pipes 13 are connected to one end of main outlet pipe 72 away from secondary filter box 54, and the four water inlet pipes 13 are connected to film stripping machine 1, plate grinding machine 2, developing machine 3 and finished product cleaning machine 4 respectively.Main outlet pipe 72 needs to be divided through water inlet pipe 13, and enters film stripping machine 1, plate grinding machine 2, developing machine 3 and finished product cleaning machine 4 respectively.

[0029] Please refer to Figure 3 ​In the embodiment, the four water inlets 13 are provided with valves 131 controlled by electric signals. The film stripping machine 1, the plate grinding machine 2, the developing machine 3 and the finished product cleaning machine 4 have different requirements for water flow. In actual production, the water flow to the film stripping machine 1, the plate grinding machine 2, the developing machine 3 and the finished product cleaning machine 4 is controlled by the valves 131 respectively to achieve the best cleaning effect.

[0030] Please refer to Figure 2 In the embodiment, the volume of the collecting tank 52 is Va and the volume of the collecting tank 61 is Vb, and Va < Vb. Since the collecting tank 61 collects wastewater from the plate grinding machine 2, the developing machine 3 and the finished product cleaning machine 4, and the collecting tank 52 only needs to collect wastewater from the film stripping machine 1, the collecting tank 61 needs to have a larger volume than the collecting tank 52.

[0031] Please refer to Figure 4 In the embodiment, the drain pipe 11 and the water inlet pipe 13 can be connected by a hose 14. When the drain pipe 11 and the water inlet pipe 13 are connected by the hose 14, an enclosed internal circulation waterway is formed between the purification system 1, the purification system 2, the branch outlet pipe 71 and the main outlet pipe 72, and a water pump 721 is further arranged on the main outlet pipe 72. The purification system 1 and the purification system 2 may be blocked after a long time of filtering and neutralizing wastewater, especially the wastewater pipe 51, which reduces the filtering cycle speed of the purification system 1 and the purification system 2 and affects production. In order to solve this problem, the film stripping machine 1, the plate grinding machine 2, the developing machine 3 and the finished product cleaning machine 4 need to be moved forward by a certain distance, and the drain pipe 11 and the water inlet pipe 13 are connected by the hose 14.

[0032] Please refer to Figure 5In the embodiment, the first filtering box 53, the second filtering box 54, the collection box one 52 and the collection box two 61 are provided with waste residue outlets 521 on the top. In the process of purification, the wastewater is blocked in the first filtering box 53 and the second filtering box 54, and then the concentrated sludge is formed. The sludge is deposited in the collection box one 52 and the collection box two 61 due to the standing. Therefore, the waste residue outlets 521 are provided on the top of the first filtering box 53, the second filtering box 54, the collection box one 52 and the collection box two 61 to facilitate the subsequent cleaning.

In the purification system one 5, the wastewater is first introduced into the collection box one 52, and then is filtered in the first filtering box 53 through the wastewater pipe 51. The wastewater filtered in the first filtering box 53 is filtered in the second filtering box 54 through the wastewater pipe 51, and then flows out of the second filtering box 54. At this time, the wastewater filtered is introduced into the branch outlet pipe 71. The water in the branch outlet pipe 71 is converged in the main outlet pipe 72, and is introduced into the inlet pipe 13 by the water pump 721. Then, the water is introduced into the film stripping machine 1, the grinding machine 2, the developing machine 3 and the finished product cleaning machine 4 through the valve one 131. At the same time, the wastewater generated by the grinding machine 2, the developing machine 3 and the finished product cleaning machine 4 is introduced into the purification system two 6 from the drain pipe 11. In the purification system two 6, the wastewater is first introduced into the collection box two 61, and then is introduced into two different first filtering boxes 53 through the wastewater pipe 51. After being filtered in the first filtering box 53, the wastewater is filtered in the second filtering box 54 through the wastewater pipe 51, and then flows out of the second filtering box 54. At this time, the wastewater filtered is introduced into the branch outlet pipe 71. The water in the branch outlet pipe 71 is converged in the main outlet pipe 72, and is introduced into the inlet pipe 13 by the water pump 721. Then, the water is introduced into the film stripping machine 1, the grinding machine 2, the developing machine 3 and the finished product cleaning machine 4 through the valve one 131.

[0034] Through the above steps, the wastewater of the film stripping machine 1 can enter the purification system 1, and the wastewater discharged by the film stripping machine 1 is filtered by the collection box 52, the first filtering box 53 and the second filtering box 54 in the purification system 1; the wastewater of the grinding machine 2, the developing machine 3 and the finished product cleaning machine 4 can enter the purification system 2, and the wastewater discharged by the grinding machine 2, the developing machine 3 and the finished product cleaning machine 4 is filtered by the collection box 61, the first filtering box 53 and the second filtering box 54 in the purification system 2, so as to solve the problem that the wastewater discharged by the film stripping machine 1, the grinding machine 2, the developing machine 3 and the finished product cleaning machine 4 is treated by a series of purification systems, and the wastewater is not purified in time when a large amount of wastewater is treated. In order to prevent the wastewater in the collection box from overflowing, the production line usually needs to be stopped, and the production line is started again after the wastewater is purified by the purification system.
