[0034] Working principle: After the lead-acid battery material is crushed, it falls from the feed hopper 102 into the feed shell 101 onto the water screen 106. The water source enters the water distribution cavity 107 from the water inlet pipe 103, and then sprays onto the material from the water spray pipe 108. The water can take away the impurities that are easily soluble in water from the material and fall into the space below the water screen 106. Then the waste water is pumped away from the device through the drain pipe 104. The second motor 403 drives the electric eddy current shaft 303 to rotate, which drives the fifth pulley 406 to rotate, and the fifth pulley 406 drives the other electric eddy current shaft 303 to rotate. The second motor 403 drives the third pulley 404 to rotate through the synchronous belt, and the third pulley 404 drives the fourth pulley 405 to rotate. The third pulley 404 drives the magnetic separation conveying belt 202 to rotate, and the fourth pulley 405 drives the rotating wheel 110 to rotate.

The cleaned material falls from the water screen 106 onto the magnetic separation conveying belt 202. The magnetic metal in the material is attracted by the special-shaped magnet 203. The magnetic separation shaft 201 rotates to drive the magnetic separation conveying belt 202 to rotate, which moves the material. The magnetic metal moves with the magnetic separation conveying belt 202 to above the magnetic metal collection box 204, and falls into the magnetic metal collection box 204 after moving out of the magnetic field of the special-shaped magnet 203. The remaining material falls into the bulk material box 310, thus completing the separation of the magnetic metal from the material. The cleaned and separated material falls into the bulk material box 310, and is dispersed by the bulk material rod 311 and then falls onto the electric eddy current conveying belt 304 on the upper side. The electric eddy current shaft 303 rotates to drive the electric eddy current conveying belt 304 to rotate, which moves the material forward. The magnetic roller 306 rotates to drive the permanent magnet 312 to rotate, generating a rapidly changing alternating magnetic field. The alternating magnetic field causes an electric eddy current in the metal in the material, which generates a magnetic field. The electric eddy current magnetic field and the permanent magnet 312 generate a repulsive force, which makes the metal fly upward. Since the repulsive force is proportional to the ratio of the electrical conductivity and density of the metal, the repulsive force on lead is smaller. By setting the distance from the first partition plate 307 to the magnetic roller 306, the remaining metal and lead can be separated. The material separated on one side falls onto the lower electric eddy current conveying belt 304, which is separated again by the lower magnetic roller 306. The lower magnetic roller 306 has more permanent magnets 312 and a larger alternating magnetic field frequency, which generates a larger repulsive force to throw the lead metal further. By adjusting the distance from the second partition plate 308 to the lower magnetic roller 306, lead and plastic can be separated, thus completing the impurity removal work on the lead material.
