The water for cooling lead ingots and slag produced by the reducing furnace is long-term circulated and rich in a large amount of heavy metals. In order to ensure environmental protection, the sewage is not discharged, and a collection well is provided on the side of the furnace for collecting and using the sewage after the heavy metals exceed the standard.

[0045] Working principle:

[0046] When the user passes the reduced furnace wastewater through the filter pipe 1, the first gear 62 is driven to rotate by starting the driving motor 65, since the first gear 62 is meshed and connected with the second gear 63, the first gear 62 and the second gear 63 are both rotationally connected with the gear box 61, at this time the first gear 62 drives the second gear 63 to rotate the transmission rod 64, the transmission rod 64 is fixedly connected with the intercepting cylinder 4, at this time the intercepting cylinder 4 also rotates, and drives the plurality of feeding pipes 71 fixed on the side wall to rotate, at this time the bailer 72 can fish the suspended particles floating on the surface of the wastewater, then with the continuous rotation of the bailer 72, the bailer 72 passes through the surface of the wastewater, under the action of gravity, the suspended particles and the fished wastewater can continuously enter the inner cavity of the feeding pipe 71, at this time the suspended particles can impact the baffle 75 downward, so that the torsional spring 74 is contracted and rotates with the rotating rod 73, at this time the baffle 75 on both sides is separated, and finally the suspended particles can enter the intercepting cylinder 4, and at this time the suspended particles in the intercepting cylinder 4 are still in the intercepting cylinder 4 under the limiting of the lower two baffles 75, and the collected wastewater can be discharged through the water leakage groove 41 provided on the intercepting cylinder 4, so that the device can realize the function of intercepting and collecting the suspended particles in the wastewater through the above-mentioned.

[0047] When the intercepting cylinder 4 rotates, when the intercepting cylinder 4 is directly below the jacking rod 82, because the lower end surface of the jacking rod 82 is fixedly provided with the magnet 84, at this time the intercepting cylinder 4 can attract the magnet 84, so that the jacking rod 82 drives the piston plate 81 to move downwards, at this time the reset spring 83 is compressed, the liquid outlet 821 on the jacking rod 82 is exposed in the inner cavity of the filter pipe 1, at this time the flocculating agent filled in the storage box 5 can be discharged through the liquid outlet 821 on the jacking rod 82 under the action of gravity, and falls into the wastewater in the filter pipe 1, at this time, with the continuous rotation of the bailer 72, the wastewater in the filter pipe 1 can be stirred, so as to increase the contact area between the flocculating agent and the wastewater, thereby effectively improving the deposition and combination of metal particles in the wastewater, and under the cooperation of the filter screen 3, the effect of intercepting and filtering the suspended particles and metal particles in the wastewater is further improved, so as to avoid that large foreign matters are sucked into the water pump, cause the water pump to be damaged, and improve the use safety performance of the subsequent water pump.
