Iron scrap recovery device for industrial waste liquid

The invention discloses an iron scrap recovery device for industrial waste liquid. The iron scrap recovery device comprises a filtering mechanism, a circulation mechanism and a collecting mechanism; and one side of the filtering mechanism is provided with the collecting mechanism, the circulation mechanism is arranged below the filtering mechanism, and the filtering mechanism is composed of a filtering box, landing legs, a diversion block, a water storage tank, a first support seat, a first motor, a drive sprocket, a second support seat, a support frame, a bearing box, a driven sprocket, an outer ring gear, a fixed cylinder, a fixed shaft, a rolling bucket and a driving gear. A permanent magnet and the water storage tank are arranged, so that the rolling bucket is in full contact with theindustrial waste liquid; under the action of the permanent magnet, the adsorption time of the permanent magnet is prolonged, the rolling bucket can absorb iron scrap in the industrial waste liquid, inaddition, the iron scrap
