Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4 A wastewater treatment device for circuit board production includes a transfer box 1, a stirring assembly, and an adjusting assembly. The adjusting assembly includes a sliding frame 2, a slider 3, a threaded screw 4, a first motor 5, and a support ring 6. The sliding frame 2 is provided on one side of the transfer box 1. The sliding frame 2 has a groove with a side opening on the side away from the transfer box 1. The threaded screw 4 and two sets of symmetrically arranged sliders 3 are arranged in the groove. The output end of the first motor 5 passes through the bottom wall of the sliding frame 2 and is connected to the threaded screw 4. The inner wall of the support ring 6 is connected to the slider 3. The support ring 6 is located below the slider 3. Below the ring 6, there is a support leg 7. At the four corners below the transfer box 1, there are moving components. The transfer box 1 is equipped with a box cover 8. The box cover 8 is equipped with an exhaust valve 13 and a stirring component. The stirring component includes a second motor 9, a rotating shaft 10 and a stirring shaft 11. The output end of the second motor 9 passes through the top wall of the box cover 8 and is connected to the rotating shaft 10. The rotating shaft 10 extends into the transfer box 1 and is equipped with several sets of stirring shafts 11. A liquid inlet pipe 12 is also provided on one side of the transfer box 1. The support ring 6 located above is also equipped with a docking component that docks with the liquid inlet pipe 12.

[0023] Waste liquid generated during circuit board manufacturing is collected by a support frame, which is positioned at a higher level for drainage. Initially, the distance between the two sets of sliders 3 is small, at which point the bottom wall of the moving component contacts the ground. The transfer box 1 can be moved via the moving component. The transfer box 1 is equipped with a cover 8. The docking assembly of the inlet pipe 12 is aligned with the drain pipe below the support frame. Then, the first motor 5 is started, which drives the positive and negative thread screws 4 inside the sliding frame 2 to rotate. The two sets of sliders 3 move towards each other, and the support ring 6 moves with the sliders 3. Several sets of support legs 7 are located below the lower support ring 6, contacting the ground and supporting the transfer box 1. This design solves the problem of inconvenience in locking the moving components when the transfer box 1 is moved below the support frame. At the same time, as the support ring 6 above rises, the docking component of the liquid inlet pipe 12 connects with the liquid outlet pipe for easy liquid discharge. The transfer box 1 is also equipped with a box cover 8, which vents through the exhaust valve 13. The liquid inlet pipe 12 stably supplies liquid, and the second motor 9 is started. The second motor 9 drives the rotating shaft 10 to rotate under the support of the box cover 8. The stirring shaft 11 stirs the waste liquid to prevent it from settling. The rotating shaft 10 is also equipped with a C-shaped scraper 22 for cleaning the inner wall of the transfer box 1, thereby preventing impurities from adhering to the inner wall of the transfer box 1.

[0024] In this embodiment, the moving component includes casters 14 and brakes 15. The casters 14 are provided at the four corners below the transfer box 1, and the brakes 15 are provided around the casters 14. The casters 14 facilitate the movement of the equipment, and the brakes 15 facilitate the fixing of the casters 14.

[0025] If the support ring 6 surrounds the transfer box 1, it may be inconvenient to push the transfer box 1. Therefore, the support ring 6 is C-shaped, and the opening of the support ring 6 is located at the end away from the slide frame 2. The transfer box 1 is also provided with a handrail 16 at the end away from the slide frame 2. The transfer box 1 can be moved by the handrail 16 in conjunction with the moving component, which makes the operation convenient.

[0026] In this embodiment, the docking assembly includes an inverted L-shaped bracket 17, bolts 18, a clamping frame 19, a connector 20, and a guide rod 21. The lower part of the bracket 17 is connected to the upper support ring 6. The top wall of the bracket 17 is located above the box cover 8, and the top wall of the bracket 17 is also provided with a sliding hole. The bolts 18 are arranged in two symmetrical sets, and the bolts 18 penetrate the side wall of the top wall of the bracket 17 and are rotatably connected to the clamping frame 19. The clamping frame 19 is also provided with a through-hole. The guide rod 21 on the top wall of 17 is used to connect the liquid inlet pipe 12 to the input end of the connector 20. The liquid inlet pipe 12 is also provided with a clamping groove that matches the clamping frame 19. The first motor 5 located below raises the support 17, which is easy to operate. Initially, the distance between the two sets of clamping frames 19 is large. The liquid inlet pipe 12 drives the connector 20 through the sliding hole, and then the clamping frame 19 is fed by the bolt 18. The clamping frame 19 moves linearly under the action of the guide rod 21 to clamp the liquid inlet pipe 12, which is easy to operate.
