Description

River silt cleaning device with prevent stifled subassembly

Technical Field

The invention relates to the field of sludge cleaning devices, in particular to a river sludge cleaning device with an anti-blocking assembly.

Background

The route of river water is usually referred to as navigable waterway. The river channel is divided into five levels, namely a first-level river channel, a second-level river channel, a third-level river channel, a fourth-level river channel and a fifth-level river channel. Silt refers to fine soil that is deposited and contains organic matter in still and slowly flowing water environments. Unconsolidated, weak or very fine grained soils deposited in still or slow flowing aqueous environments, formed by physicochemical and biochemical processes. Belongs to modern new sediment. The sludge may be silt or clayey in size composition, with very little or very fine sand. The clay minerals of the seaside sludge are mainly illite and montmorillonite, and the fresh water sludge is mainly illite and kaolinite. The sludge contains more (2-3%) and more (10-12%) organic matter, the content of which decreases with depth.

Generally in the silt extraction processing work in narrow river course, all directly adopt the pump of taking out dirty to carry out direct extraction to river bottom silt, but probably contain the plastic bag in the inside of silt, if the plastic bag is extracted by the pipeline of dredge pump, just probably cause the jam of pipeline, and the position and the angle of extraction pipeline at the river bottom are difficult to adjust, and the silt of not being convenient for is extracted, and silt deposits at the river bottom, and the direct extraction needs the more degree of difficulty.
