I. Core Working Principle
* Siphon-type Gold Dredger: Driven by a diesel/electric motor, a high-lift centrifugal pump creates localized negative pressure as high-pressure water flows through a specially designed U-shaped siphon head, drawing gold-bearing sand from the riverbed into the pipe. The sand does not pass through the pump impeller, significantly reducing equipment wear.
* Siphon-type Water Pump Boat: Utilizes the siphon principle to achieve gravity-flow pumping. A special flow channel design reduces net positive suction head (NPSH), resulting in energy consumption approximately 60% lower than traditional pump boats.
II. Main Types and Applications
* 1. Siphon-type Gold Dredger (Most Common)
* Structure: Hull, siphon pipe, power system, pulsating sluice/gold panning mat, water circulation system.
Specifications: 2-inch, 3-inch, 4-inch, 6-inch, etc., processing capacity 2–10 m³/h, suitable for water depths 1–20 meters.
Advantages: High fine-grained gold recovery rate: 85%–95%, superior to traditional manual and chain bucket equipment.
Lightweight and easy to assemble and disassemble; can be operated by a single person; suitable for narrow rivers, shallow water areas, and remote mining areas.
Closed-loop water circulation, low tailings discharge, environmentally friendly and energy-saving.
Applications: Small-scale placer gold mining in rivers, streams, and shallows; supplementary equipment for areas where large equipment cannot operate.
2. Siphon-type Water Intake Pump Boat
Uses: Reservoir water intake, urban emergency water supply, river dredging, industrial water extraction.
Features: Flow rate 500–5000 m³/h, wind and wave resistant, modular, rapid deployment, significant energy savings.
III. Key Advantages
Low wear: Material does not pass through the pump impeller, significantly extending equipment life and maintenance cycle.
High efficiency and energy saving: Gold dredging vessels consume 30%–40% less energy; water pumping vessels consume 60% less energy.
Flexible and adaptable: Small size, easy to transport, and adaptable to complex terrain and water level fluctuations.
