Electric Submersible Dredge Pump with Cutter Head

The electric submersible dredge pump with cutter head is a system comprising a submersible sand pump and a cutting head attachment. This pump is driven by electricity and can be fully submerged underwater. The cutting head is positioned at the pump’s inlet and features a rotating cutting tool that disintegrates compacted soil, rocks, and debris, creating slurry that can be easily sucked into the pump for removal. This integrated system leverages the combined functions of the pump and cutting head to effectively excavate and clear materials from underwater areas.

Working Principle:

Electric Power: The system is powered by a generator, which provides the power to drive the pump and operate the cutting head.
Submersible Design: The dredge pump with a cutting head is designed to be submersible. This means it can be fully immersed underwater, enabling operation in areas with varying water levels.
Dredge Pump: The dredge pump is responsible for suctioning sediment, slurry, and other materials from the waterbed. It generates a vacuum through the rapid rotation of an impeller, drawing in water and its contents.
Cutting Head: The cutting head is an attachment located at the inlet of the dredge pump. It is equipped with a rotating cutting tool that breaks down compacted soil, rocks, and debris on the waterbed. This pre-cutting action makes it easier for the pump to intake loose materials.
Sand Suction: The cutting head is located near the pump’s inlet. which transports the mixture of water and sediment from the cutting area to the pump.
Pumping and Discharge: The pump then propels the mixture of water and sediment through a discharge pipe. The pump imparts kinetic energy to the mixture, causing it to flow through the pipeline and be conveyed to a designated location.
Separation: Upon reaching its destination, the mixture may be directed to separation equipment. This equipment aids in separating water from the dredged material, allowing water to return to the water body while collecting sediment for further processing or disposal.

This hydraulic submersible dredge pump with cutter head finds wide-ranging applications, including channel maintenance dredging, land reclamation, environmental cleanup, and underwater construction projects. By effectively combining cutting and pumping functions, it serves as a versatile tool for maintaining waterways and ensuring their proper functioning.
