Self-circulation multi-step silt solidification cleaning device

The utility model discloses a self-circulation multi-step silt solidification cleaning device which comprises a mud storage tank, a treatment tank, a middle framework, a low framework, a concentration basin, a concentrated mud basin, a flocculating agent preparing and filling system and silt solidification equipment. The self-circulation multi-step silt solidification cleaning device is characterized in that two pretreatment vibrating screens are mounted on the top of the mud storage tank, three sand pumps of the mud storage tank are mounted on the side surfaces of the bottom of the mud storage tank, primary mud ditches are connected to the lower portions of the pretreatment vibrating screen and are connected with inlet glass fiber reinforced plastic pipes of the treatment tank, the inlet glass fiber reinforced plastic pipes of the treatment tank are connected with the treatment tank, three cyclones are mounted on the top of the treatment tank, three input sand pumps of the cyclones are mounted on the side surfaces of the bottom of the treatment tank, secondary mud ditches are connected to the side surfaces of the upper portions of the cyclones, sieves are arranged at the bottoms of the cyclones, the secondary mud ditches are connected with outlet glass fiber reinforced plastic pipes of the treatment tank, and the outlet glass fiber reinforced plastic pipes of the treatment tank are connected with the mud storage tank. The self-circulation multi-step silt solidification cleaning device has the advantages that silt can be cleaned on a large scale without storage yards, can be subjected to synchronous dehydration and solidification operation and can be cleaned when generated on a daily basis, and the self-circulation multi-step silt solidification cleaning device is low in investment and operating cost, free of noise and high in efficiency and automation degree.
