One side of one end of the No. 2 telescopic rod 524 is fixedly connected to the No. 3 shaft 527, and one side of the baffle block 523 is fixedly connected to the No. 3 telescopic rod 5232 for cooperating to change the position of the baffle block 523 in the baffle block groove 5222, and one end of the No. 3 telescopic rod 5232 is slidably connected in the W-shaped groove 5291.

[0029] The use principle of a magnetic separation heavy metal sewage treatment equipment provided by the present invention is as follows: First, the stirred sewage and the flocculent pollutants mixed with magnetic seeds are transported from the transport pipe 6 to the magnetic plate 51 on one side of the secondary box 1. In this process, the sewage and the flocculent pollutants mixed with magnetic seeds are changed from the original columnar shape to a flat shape after passing through the guide plate 312, thereby increasing the contact area with the magnetic plate 51. Since the guide plate 312 is always facing a position on the magnetic plate 51, more and more flocculent pollutants mixed with magnetic seeds are adsorbed at this position, and the filter hole 511 in this area is blocked, and the sewage can no longer be filtered downward, so that the sewage collected in the water storage chamber 3321 below this position is relative to the water storage chamber 33 below the area where the magnetic plate 51 is not blocked. The sewage collected in the No. 1 water storage box 332 is less, and the No. 1 water storage box 332 deflects to the non-blocking area of ​​the guide plate 312 and the magnetic suction plate 51, thereby realizing automatic adjustment of the guide plate 312 to deflect toward the position of the magnetic suction plate 51 that is not transported. This is achieved by adjusting the gravity of the water stored in the water storage chamber 3321 at both ends of a group of No. 1 water storage boxes 332, and the inclination of the C-shaped plate 311 is adjusted according to the gravity of the water stored between the two groups of No. 1 water storage boxes 332, which effectively improves the automation of the equipment and the efficiency of completely absorbing the flocculated pollutants mixed with magnetic seeds on the upper surface of the magnetic suction plate 51, so as to quickly carry out the adsorption work of the next group of magnetic suction plates 51, effectively improving the work efficiency; At the same time, when the magnetic plate 51 is filtering sewage downward, part of the sewage falls into the No. 2 water storage box 522 from the drain trough 5212. When the upper surface of the magnetic plate 51 is blocked by flocculent pollutants mixed with magnetic seeds, the amount of sewage collected in the two groups of No. 2 water storage boxes 522 is different, and the area of ​​the magnetic plate 51 above the No. 2 water storage box 522 that collects more sewage is better unblocked, while the area of ​​the magnetic plate 51 above the No. 2 water storage box 522 that collects less sewage is worse unblocked. At this time, the heavier group of No. 2 water storage boxes 522 moves downward, and drives the lighter group of No. 2 water storage boxes 522 to move downward through the seesaw principle. 2 moves upward, and the second water storage box 522 of the lighter group moves upward, driving the square plate 521 above it to move upward, so that the dredging block 5211 is inserted into the filter hole 511, so that the accumulated flocculated pollutants mixed with magnetic seeds are pushed away and adsorbed by other areas of the magnetic suction plate 51, so that the filter hole 511 is dredged, which effectively promotes the efficiency of sewage filtration and thus improves the work efficiency. The purpose of the conical design of one end of the dredging block 5211 is to facilitate the wet flocculated pollutants to slide from the conical surface to the outside of the filter hole 511 under their own gravity, so that the flocculated pollutants are better adsorbed by other areas of the magnetic suction plate 51; In the initial state, the baffle block 523 is completely located in the baffle block groove 5222, the No. 1 drain hole 5221 is completely staggered from the No. 2 drain hole 5231, and the baffle block 523 completely separates the interior of the No. 2 water storage box 522 from the No. 1 drain hole 5221, so that the No. 2 water storage box 522 can collect sewage. When one group of No. 2 water storage boxes 522 moves upward along the W-shaped groove 5291 and the other group of No. 2 water storage boxes 522 moves downward along the W-shaped groove 5291, the two groups of No. 3 telescopic water storage boxes 522 are connected to each other. The rods 5232 are respectively limited by the W-shaped grooves 5291 and move toward the outside of the blocking block groove 5222. This process causes the No. 1 drain hole 5221 to begin to overlap with the No. 2 drain hole 5231. The blocking block 523 no longer separates the interior of the No. 2 water storage box 522 from the No. 1 drain hole 5221. The two groups of No. 2 water storage boxes 522 begin to discharge the collected sewage downward along the No. 1 drain hole 5221 and the No. 2 drain hole 5231 to facilitate the next group of dredging work on the magnetic suction plate 51.
