Description

Sludge precipitator and mud-water separation device Technical Field The utility model relates to the technical field of river dredging, in particular to a sludge precipitator and a mud-water separation device. Background In river course treatment and maintenance practice, sludge treatment is an important and complex link. Under the influence of long-term natural deposition and human activities, a large amount of sludge can be accumulated in the river channel, and the sludge not only occupies the effective flow cross section of the river channel and influences the flood discharge capacity of the river channel, but also can form potential threat to the water body environment due to the fact that the sludge is rich in pollutants. Therefore, the dredging operation is carried out on the river channel at regular intervals, and the dredging operation is a necessary measure for guaranteeing the smooth river channel and maintaining the ecological balance of water. The traditional river dredging method adopts a mechanical or hydraulic suction mode to directly pump out the sludge in the river and transfer the sludge to a stacking place. However, this method has a significant problem in that the directly extracted sludge has an extremely high water content, usually containing a large amount of free water and bound water, and often has a water content exceeding 95%. The sludge with high water content is huge, increases the transportation and storage cost, and is not easy to be processed and utilized later. In addition, the high-water-content sludge is easy to percolate in the stacking process, so that secondary pollution is caused, and adverse effects are generated on the surrounding environment. To overcome this problem, the industry is continually searching for more efficient, environmentally friendly sludge treatment techniques. At present, although some schemes for attempting to reduce the water content of the sludge by natural airing, mechanical dehydration or chemical conditioning and the like exist, the methods are long in time consumption and low in efficiency, are high in cost and difficult to popularize on a large scale, or new pollutants can be introduced in the treatment process, so that the subsequent utilization value of the sludge is influenced. In view of this, there is a need for improvements to existing processing apparatus to address the above-described problems. Disclosure of utility model The utility model aims to provide a silt precipitator so as to solve the problem that the water content of silt generated by dredging the existing river is high. In order to achieve the above purpose, the utility model provides a sludge settler, which comprises a sedimentation tank and a plurality of multi-folded plates arranged in the sedimentation tank, wherein the sedimentation tank is provided with an inlet for introducing sludge water, an outlet arranged at one side far away from the inlet and used for discharging muddy water, and a sludge discharging port arranged at the bottom and used for discharging sludge, the multi-folded plates are arranged between the inlet and the outlet and are arranged in parallel, the spacing direction of the multi-folded plates is consistent with the spacing direction of the inlet and the outlet, the multi-folded plates at least comprise a first inclined plate arranged below and a second inclined plate connected with the upper end of the first inclined plate, the first inclined plate and the second inclined plate are both arranged obliquely with the vertical direction and the horizontal direction, and the included angle between the first inclined plate and the horizontal direction is larger than the included angle between the second inclined plate and the vertical direction. As a further improvement of the present utility model, the first sloping plates of the plurality of multi-folded plates are all arranged in parallel, and the second sloping plates of the plurality of multi-folded plates are arranged in parallel. As a further development of the utility model, the distance between two adjacent multi-flaps is 30cm.
