[0002] During the disassembly process of lead-acid batteries, lead plates and lead mud are recycled, and sulfuric acid waste liquid has become the main pollution source. Since the sulfuric acid solution contains heavy metal ions such as lead, iron, manganese, and copper, it cannot be discharged externally. A small lead-acid battery, when discarded into the ground, can pollute one square meter of land. Through the land, lead can enter the food chain, and excessive lead absorption by the human body will cause a series of consequences such as slow thinking and reaction. The treatment of waste acid from lead-acid batteries has become an important task and is also a matter of great concern to the national environmental protection department.

[0003] The waste acid collection and recycling device is a device that filters impurities from the waste acid during the disassembly process of lead-acid batteries for subsequent treatment and reuse. During the waste acid collection process, due to impurities in the waste acid, after the filtering mechanism filters a certain amount of waste acid, the filtering mechanism needs to be cleaned and maintained. When cleaning and maintaining the filtering mechanism, shutdown operations are required, which is very inconvenient for cleaning and maintaining the filtering mechanism and also affects the processing efficiency.

[0029] Embodiment 1

[0030] As Figure 1 and Figure 2 shown, this embodiment provides a waste acid collection and recycling device, including a collection box 1. Drain valve pipes 2 are fixedly connected to both sides of the collection box 1. A sewage discharge valve pipe 3 is fixedly connected to one end of the collection box 1. Demounting grooves 17 are opened at both ends of the collection box 1. An adjusting mechanism 4 is arranged at the top of the collection box 1. A diversion mechanism 5 is arranged at the top of the adjusting mechanism 4. The diversion mechanism 5 is used to guide the discharge of waste acid. A pair of filtering mechanisms 6 are arranged at the bottom of the adjusting mechanism 4. Both of the pair of filtering mechanisms 6 are used to filter waste acid.

[0031] Through the provided diversion mechanism 5, it can be interconnected with the waste acid discharge pipe. The waste acid is discharged into the filtering mechanism 6 through the diversion mechanism 5. The filtering mechanism 6 is used to filter the waste acid, and the impurities mixed in the waste acid can be filtered and retained inside the filtering mechanism 6. The adjustment mechanism 4 provided at the top end of the collection box 1 can, according to actual operation requirements, cooperate with the filtering mechanism 6 and the diversion mechanism 5 using the adjustment mechanism 4 to adjust the positions of the filtering mechanism 6 and the diversion mechanism 5, meeting the operation requirements of replacing and cleaning the filtering mechanism 6 and adjusting the position of the diversion mechanism 5 to change the liquid discharge position.

[0032] As Figures 1 to 5 shown, the adjustment mechanism 4 includes a sliding frame 7 fixed to the top end of the inner wall of the collection box 1. The top end of the sliding frame 7 is fixedly connected to a support frame 8. The top end of the support frame 8 is fixedly connected to a top frame 9. A positioning pin hole is provided at the top end of the top frame 9. A limiting chute 12 is provided at the bottom end of the sliding frame 7. The sliding frame 7 is a sliding frame with a curvature. The sliding frame 7, the support frame 8, and the top frame 9 are of an integral structure. The diversion mechanism 5 includes a limiting sliding frame 10 slidably mounted on the outer wall of the top frame 9. One side of the limiting sliding frame 10 is fixedly connected to a diversion box 11. A positioning pin is fixed to the top end of the limiting sliding frame 10. The limiting sliding frame 10 and the diversion box 11 are of an integral structure. A limiting chute 12 is provided at the bottom end of the sliding frame 7. A filter box 13 is slidably mounted at the bottom end of the limiting chute 12 through a slider. One end of the filter box 13 is matched with a disassembly groove 17. A filter screen plate 15 is fixedly connected to the bottom end of the filter box 13. One end of the filter box 13 is fixedly connected to a sealing partition plate 14 through a hinge. Positioning clamping plates 16 are fixedly connected to both sides of the sealing partition plate 14. The positioning clamping plates 16 are snap-connected to the side wall of the filter box 13 through snap protrusions.

[0033] The sliding frame 7 fixed to the top end of the inner wall of the collection box 1 can move the filter box 13 slidably mounted at the bottom end of the limiting chute 12 through a slider, so that the filter box 13 is separated from the collection box 1, facilitating the cleaning, maintenance, and replacement operations of the filter box 13. Moreover, during the maintenance operation of a single filter box 13, the position of the diversion box 11 can be changed by moving the limiting sliding frame 10 on the outer wall of the top frame 9, thereby adjusting the liquid discharge position. The waste acid is filtered using another filtering mechanism 6 with the same structure at the bottom end of the sliding frame 7, so that the situation of needing to stop the machine for replacing and cleaning the filter box 13 will not occur, improving the waste acid filtering efficiency. The filter screen plate 15 fixedly connected to the bottom end of the filter box 13 can filter larger impurities in the waste acid and retain them inside the filter box 13, facilitating centralized collection and cleaning. By moving the sealing partition plate 14 fixedly connected to the filter box 13 through a hinge, after the entire filter box 13 is slid out, the positioning clamping plates 16 fixedly connected to both sides of the sealing partition plate 14 can be disassembled, and the sealing partition plate 14 is reversed, so that one end of the filter box 13 is in an open state, facilitating the quick dumping of the sundries located inside the filter box 13 and improving the internal cleaning efficiency of the filter box 13.

[0034] AsFigures 1 to 5 As shown, a flow buffer plate 18 is fixedly connected inside the collection box 1. The flow buffer plate 18 is arranged in an inverted U shape, and there are gaps between both ends of the flow buffer plate 18 and the inner wall of the collection box 1. Through the flow buffer plate 18 arranged in an inverted U shape inside the collection box 1, the acid liquid discharged after being filtered by the filter box 13 can be guided for slow flow, preventing the liquid from dripping directly and causing excessive tumbling of the liquid at the bottom end inside the collection box 1, which may affect the precipitation effect of the acid liquid. The gaps arranged between both ends of the flow buffer plate 18 and the inner wall of the collection box 1 are used for the liquid to slowly enter the bottom end inside the collection box 1 through the gaps.

[0035] As Figure 4 and Figure 5 shown, a filter cylinder 19 is fixedly connected inside the collection box 1. Both ends of the filter cylinder 19 are respectively in internal communication with the inside of the drain valve pipe 2. The filter cylinder 19 is located directly below the flow buffer plate 18. Through the filter cylinder 19 fixedly connected inside the collection box 1, when a certain amount of waste acid is collected in the collection box 1, it is convenient to conduct secondary filtration on the waste acid through the filter cylinder 19, and then discharge it through the drain valve pipe 2 for recycling.

[0036] As Figure 4 and Figure 5 shown, the bottom end inside the collection box 1 is arranged in an arc shape, and the bottom end inside the collection box 1 is inclined towards the sewage discharge valve pipe 3. The collection box 1 with an arc-shaped bottom end inside is convenient for the sediment to tilt towards the sewage discharge valve pipe 3 under the influence of gravity after the waste acid has precipitated, thereby facilitating the discharge of the sediment.

[0037] As Figures 1 to 5 shown, the sealing partition plate 14 is made of a metal plate with a magnet fixed inside, and a rubber sealing strip is fixedly connected to the inner wall of the sealing partition plate 14. The sealing partition plate 14 with a magnet fixed inside is convenient for further improving the stability of the filter box 13 inside the collection box 1 through the mutual adsorption of the sealing partition plate 14 when the sealing partition plate 14 and the filter box 13 enter the collection box 1 for the two identical filtering mechanisms 6.

[0038] As Figures 1 to 5 shown, the filter mesh plate 15 is a filter mesh plate with a curvature. The filter mesh plate 15 with a curvature can make the sundries tilt and accumulate towards one side, which is convenient for cleaning, and can also prevent the holes of the filter mesh plate 15 from being completely covered by sundries, affecting filtration and causing acid liquid to overflow.

[0039] Working steps

[0040] Step 1: Connect the drain valve pipe 2 with the acid neutralization treatment box body, and connect the waste acid discharge pipe with the diversion box 11. The waste acid together with sundries is discharged into the filter box 13 through the diversion box 11 for filtration. The filtered waste acid drips onto the inside of the collection box 1 through the filter mesh plate 15. During the dripping process of the waste acid, the flow retarder plate 18 inside the collection box 1 can reduce the impact force generated by the dripping of the waste acid, thereby reducing the shaking degree of the waste acid inside the collection box 1 and improving the precipitation effect of the waste acid. After the precipitation, the waste acid is filtered through the filter cylinder 19 inside the collection box 1 and then discharged through the drain valve pipe 2, completing the filtration operation in the waste acid recycling process. After acidity neutralization, it can be reused again.

[0041] Step 2: According to the actual operation requirements, slide the filter box 13 along the sliding frame 7 so that one end of the filter box 13 disengages from the disassembly groove 17 and then completely disengages from the collection box 1. Disassemble the positioning clamping plates 16 on both sides of the sealing partition plate 14, and then flip the sealing partition plate 14 through the hinge to clean the sundries accumulated in the filter box 13 during filtration. Before cleaning and maintaining a single filter box 13, by means of the limit sliding frame 10 on the outer wall of the sliding top frame 9, the position of the diversion box 11 can be changed, and then the drain port of the diversion box 11 can be moved to the top of another filter box 13, thus avoiding the situation of needing to stop the machine for maintaining the filter box 13. When there is too much sediment at the bottom inside the collection box 1, open the sewage discharge valve pipe 3 to discharge the sediment. The sewage discharge valve pipe 3 can also be connected with the flushing pipe to inject liquid in the reverse direction into the collection box 1 to flush and clean the bottom inside the collection box 1.

[0042] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
