Each stage of cleaning has a special sprayer for spray cleaning to ensure that the impurities and acidic solution on the surface of the copper alloy wire are completely removed; this multi-stage cleaning method can significantly improve the cleaning effect, reduce residues, and ensure the quality of the wire; specifically, the first sprayer 307, the second sprayer 410 and the third sprayer 503 spray cleaning liquid outward through the liquid inlet pipe 7 to clean the alloy wire;

[0036] Among them, after the alloy wire in the final washing chamber 3 has been washed in the first two stages, most of the impurities and acidic solutions remaining on its surface have been washed away. At this time, the cleaning liquid sprayed by the first sprayer 307 performs the final stage of washing on the copper alloy wire. After the washing solution is filtered by the first filter component to remove impurities, it flows into the clean water chamber 403 through the first connecting hole 308;

[0037] After the first pump body 411 is powered on, it can pump the solution in the clean water chamber 403 into the second sprayer 410 as a supplementary water source for the second sprayer 410, and can rinse the alloy wire in the re-washing chamber 4; and, after the solution sprayed by the second sprayer 410 in the re-washing chamber 4 is filtered by the second filter component, it enters the partition chamber in the primary washing chamber 5 through the second connecting hole 408. After the second pump body 504 is powered on, it can pump the solution in the partition chamber into the third sprayer 503 as a supplementary water source for the third sprayer 503, and can rinse the alloy wire in the primary washing chamber 5; by setting the first filter component, the second filter component, the first connecting hole 308 and the second connecting hole 408, the recycling of the cleaning liquid is realized, the waste of water resources is reduced, and the production cost is reduced.

[0039] A first sewage pipe 306 is provided in the final washing chamber 3. One end of the first sewage pipe 306 is located on the upper side of the first filter screen 305, and the other end passes through the first bottom plate 301 and then passes obliquely downward to the outside of the final washing chamber 3.

[0040] A vent hole for contacting with the external atmosphere is provided at the top of the first communication hole 308;

[0041] In this embodiment, after the cleaning liquid sprayed by the first sprayer 307 rinses the alloy wire, it is collected at the first water drop hole 302 through the first bottom plate 301 and flows out from the upper side of the first filter screen 305 through the first guide pipe 303, and then after being filtered by the first filter screen 305, it flows into the clean water cavity 403 in the rewashing chamber 4 through the first connecting hole 308;

[0042] In addition, through the first sewage pipe 306, as the impurities on the first filter 305 gradually increase, the water pressure on the upper side of the first filter 305 will gradually increase, so the liquid level in the first sewage pipe 306 will gradually rise. When the liquid level in the first sewage pipe 306 is higher than the highest point of the first sewage pipe 306, the liquid in the first sewage pipe 306 will flow out and a siphon phenomenon will occur, and a steady stream of solution will be drawn out. At this time, the solution in the final washing chamber 3 will pass through the first filter 305 from bottom to top to flush the impurities on the first filter 305 upward, and the impurities will be discharged outward through the first sewage pipe 306 with the solution, thereby backwashing the first filter 305. When the liquid level in the final washing chamber 3 is lower than the first sewage pipe 306, air enters the first sewage pipe 306 to destroy the siphon phenomenon, and the backwashing operation of the first filter 305 is automatically terminated.

[0044] A second sewage pipe 409 is provided in the re-washing chamber 4. One end of the second sewage pipe 409 is located on the upper side of the second filter screen 405, and the other end passes through the second bottom plate 401 and then passes obliquely downward to the outside of the re-washing chamber 4.

[0045] The top of the second communication hole 408 is also provided with a vent hole for contacting with the external atmosphere;

[0046] In this embodiment, after the solution sprayed by the second sprayer 410 flushes the alloy wire, it will flow out from the upper side of the second filter screen 405 through the second drainage hole 406 on the second bottom plate 401 and the second guide pipe 407. After being filtered by the second filter screen 405, the outflowing liquid flows into the partition cavity through the second connecting hole 408 as a supplementary water source for the third sprayer 503.

[0047] Through the second sewage pipe 409 that is set, as the impurities on the second filter screen 405 gradually accumulate, the water pressure on the upper side of the second filter screen 405 will gradually increase, so the liquid level in the second sewage pipe 409 will gradually increase. When the liquid level in the second sewage pipe 409 is higher than the highest point of the second sewage pipe 409, the liquid in the second sewage pipe 409 will flow out and a siphon phenomenon will occur, and a steady stream of solution will be drawn out. At this time, the solution in the rewashing chamber 4 will pass through the second filter screen 405 from bottom to top to flush the impurities on the second filter screen 405 upward, and the impurities will be discharged outward through the second sewage pipe 409 with the solution, thereby backwashing the second filter screen 405; when the liquid level in the rewashing chamber 4 is lower than the second sewage pipe 409, air enters the second sewage pipe 409 to destroy the siphon phenomenon, and the backwashing operation of the second filter screen 405 is automatically terminated.

[0048] Preferably, a sewage trough 6 is provided on the rear side of the washing tank 2, and the sewage trough 6 is located at the bottom of the outlet pipe 501, the second sewage pipe 409 and the first sewage pipe 306, for collecting sewage discharged from the three; wherein, one side of the sewage trough 6 is connected to a drain pipe 601, for discharging the sewage collected in the sewage trough 6 to an external sewage treatment system.

[0049] The copper alloy wire pickling device provided by the present invention, through the first filter component, the second filter component, the first connecting hole 308 and the second connecting hole 408, can pump the solution in the clean water chamber 403 into the second sprayer 410 as a supplementary water source for the second sprayer 410 after the first pump body 411 is powered on, and can wash the alloy wire in the re-washing chamber 4; and the solution sprayed by the second sprayer 410 in the re-washing chamber 4 enters the partition chamber in the primary washing chamber 5 through the second connecting hole 408 after being filtered by the second filter component, and the second pump body 504 can pump the solution in the partition chamber into the third sprayer 503 as a supplementary water source for the third sprayer 503 after being powered on, and can wash the alloy wire in the primary washing chamber 5; the recycling of the cleaning liquid is realized, the waste of water resources is reduced, and the production cost is reduced.
