Product Overview
The ZCX series central-drive single/double pipe suction machine is
designed for large and medium-sized sedimentation tanks with
peripheral water intake/discharge and central sludge discharge. It
is widely used in urban wastewater treatment plants for efficient
sludge extraction in secondary sedimentation tanks.
Key Parameters
Additional Specifications:
Tank Depth: 3.5–4.5 m (customizable)
Side Water Depth: 3.0–4.0 m (customizable)
Installation Dimensions: Customized based on user requirements
Applications
Ideal for:
Urban wastewater treatment plants
Secondary sedimentation tanks
Large and medium-sized circular sedimentation tanks with peripheral
inflow/outflow and central sludge discharge
Structure & Working Principle
The system adopts a central transmission vertical frame design:
Wastewater enters through a peripheral distribution tank and flows
uniformly into the sedimentation tank.
A peripheral skirt guides water from the tank bottom toward the
center, promoting sludge settling.
The central drive rotates the vertical frame, sludge scraper arms,
and suction pipes.
Sludge enters suction ports via hydrostatic pressure and is
discharged through a central sludge pipe with a sleeve valve for
flow control.
Floating scum is skimmed to the periphery and removed by a scraper
mechanism.
Treated effluent flows over a triangular weir into the outlet
trough.
Key Features
Uniform Flow Distribution: Peripheral inlet/outlet troughs with side sections ensure
balanced hydraulic loading.
Robust Drive System: Helical and worm gear reducers provide high torque and reliable
operation with overload protection.
Adaptable Scraper Design: Single-arm scraper for tanks ≤40m; double-arm for tanks >40m.
Efficient Sludge Extraction: Horizontal perforated pipes minimize disturbance to density
currents and improve sludge concentration.
Variable Orifice Spacing: Tapered suction pipes with progressively spaced orifices ensure
uniform sludge extraction and higher solids concentration.
Flexible Skimming Options: Choice of plate skimming (standard) or pipe skimming.
Automated Operation: Local and remote control capabilities for seamless integration
into plant management systems.
Ideal For:
Municipal wastewater treatment plants, industrial water recycling
facilities, and large-scale sedimentation tank applications
requiring reliable and efficient sludge removal.
