The invention discloses a
hydraulic engineering desilting device and method, and belongs to the technical field of
hydraulic engineering. A
hydraulic engineering desilting device comprises a filter box, an obliquely-arranged filter screen plate is arranged in the filter box, the top of the filter box is connected with a connecting
pipe, the connecting
pipe communicates with a
temporary storage shell, the end, away from the connecting
pipe, of the
temporary storage shell is connected with a
silt pumping pipe, a pump body is arranged on the
silt pumping pipe, and a
silt outlet is formed in the bottom of the connecting pipe; a silt outlet is formed in the filter box, a floating
assembly used for blocking the silt outlet is arranged in the filter box, a clamping
assembly used for limiting movement of the floating
assembly is arranged in the filter box, a silt discharging opening is formed in the filter box, the silt discharging opening is formed in the bottom end of the filter screen plate, a baffle is movably connected to the silt discharging opening, and a
sewage discharging assembly is arranged on the filter box; while the river
sludge cleaning efficiency is guaranteed,
sludge and
sewage are effectively separated, later
sludge cleaning and transportation are facilitated, the possibility of secondary
pollution to the surrounding environment in the transportation process is prevented, the working efficiency is improved, and the labor cost is saved.
