Siphon Sand Suction System - High-Efficiency Desanding Equipment with Eddy Current Submersible Pump
The Bridge-Type Siphon Sand Suction Machine is engineered for efficient grit removal in aeration grit tanks at sewage treatment plants. Combining a siphon-based suction mechanism with an eddy current submersible pump, this system ensures seamless extraction of sand and debris with minimal energy consumption. Its simple structure and automated operation make it ideal for municipal and industrial wastewater applications.
Automated Traversing:
The machine moves along rails installed over the grit settling tank, covering the entire tank width.
Siphon-Enhanced Suction:
A vortex submersible pump (eddy current design) extracts sand-water mixtures from the tank bottom.
Siphon action amplifies suction efficiency, reducing pump workload.
Integrated Skimming:
An optional skimmer blade removes surface scum, directing it to a slag trough.
Grit Separation:
Extracted混合物 is delivered to a gravel separator for dewatering and organic matter removal.
