Durable QXS Series Siphon Sand Suction System - Non-Clogging Desanding Equipment
The QXS Bridge-Type Sand Suction Machine is engineered for grit removal in aeration grit tanks at urban sewage treatment plants and water facilities. It efficiently extracts settled sand, cinder, and large particles from tank bottoms, discharging them into adjacent sand collection tanks. Optional oil skimming and slag removal attachments are available for customized operations.

Bridge-Mounted Design:
Mobile bridge structure traverses rails over the grit tank, enabling full coverage.
Integrates a submersible pump for direct suction of sand-water mixtures.
Automated Operation:
At rest, the machine stations at the tank inlet.
Upon activation, it moves under electrical control, simultaneously suctioning sand and skimming surface scum.
Dual-Function Process:
Sand Suction: A vortex submersible pump extracts grit via a suction pipe, discharging it into a sand collection tank.
Slag Skimming: A scraper blade removes floating scum, directing it to a slag trough at the tank end.
Reciprocating Mechanism:
Forward movement engages sand suction and skimming.
Reverse motion lifts the skimmer to prevent backflow, ensuring continuous efficiency.
Grit Processing:
Extracted grit flows to a sand-water separator for further treatment.
Non-Clogging Pump Technology:
Vortex submersible design eliminates blockages and reduces wear.
No water diversion required, simplifying operation.
Durable Construction:
Corrosion-resistant materials (e.g., stainless steel critical components).
Robust rail system rated for heavy-duty use.
Odor-Free Output:
Aerated grit circulation removes organic matter, preventing foul odors.
Dual Control Options:
Local manual control or remote automation via PLC systems.
Low Maintenance:
Simple structure with minimal moving parts.
Long service life under harsh wastewater conditions.
High Efficiency:
Recovers ≥95% of particles ≥0.2mm.
Processes up to 30 m³/h of sand-water mixture.
For Heavy Sediment Loads: Opt for dual-pump models (QXS-10/QXS-12) to prevent overload.
In Cold Climates: Specify frost-resistant materials and insulation for year-round operation.
Retrofit Projects: Custom rail designs available to fit existing tank structures.
Automation Integration: Pair with IoT sensors for real-time grit level monitoring and predictive maintenance.
