Description

Technical Field

[0001] The utility model relates to the field of river silt treatment, and more specifically to silt treatment equipment for water environment management. Background Art

[0002] The conventional practice for the silt cleared from the river is to compost it so that it can be used as organic fertilizer, or to drain the silt through a sludge filter press and use the dry mud cake for road hardening.

This method has a high utilization rate of dry mud cake, a large consumption of dry mud cake, and the strength of the produced floor tiles also meets the requirements. For the mixing of dry mud cake and clay, the existing technology uses an ordinary mixer to mix the two. However, due to the characteristics of clay itself, it is easy to stick to the wall or form lumps. The dry mud cake and clay cannot be fully mixed, and the quality of the produced floor tiles is unstable, which hinders the promotion of this sludge treatment method.
