AI Technical Summary
Technical Problem
Existing dredging equipment for water conservancy projects suffers from incomplete dewatering during the sludge dewatering process, which increases the difficulty of subsequent transportation and treatment and is not conducive to the resource utilization of sludge.
Method used
A depth-adjustable dredging device for water conservancy projects is adopted. By agitating and squeezing the sludge with blades, combined with the spraying of alkaline regulators and hot air drying, the sludge is fully dehydrated and modified.
Benefits of technology
It improves the dewatering efficiency and thoroughness of sludge, reduces equipment energy consumption, and improves the chemical and physical properties of sludge, facilitating subsequent resource utilization.

Abstract
This invention relates to the field of river dredging technology, and more particularly to a depth-adjustable dredging device for water conservancy projects, comprising a mobile carrier; a suction assembly disposed on one side of the mobile carrier for suctioning silt; and a dewatering mechanism, comprising a storage box fixed to the mobile carrier, a dewatering cylinder above the storage box, a rotating shaft A driven by a motor inside the dewatering cylinder, a sleeve slidably fitted on the outer wall of the rotating shaft A, and multiple sets of blades rotatably mounted on the outer wall of the sleeve; and an electric cylinder B disposed on one side of the storage box, the output end of which is rotatably connected to the sleeve via a bearing. When the rotating shaft A drives the multiple sets of blades to rotate, the blades can fully agitate and break up the falling silt, effectively avoiding the problem of incomplete dewatering caused by centrifugal filtration in traditional dredging devices, thus making the silt looser and more uniform, and improving the silt modification effect.
