一、Product Introduction
The Haipou Environmental Protection peripheral-drive sludge scraper is a fully automated, integrated unit designed specifically for circular radial-flow sedimentation tanks. Widely used in municipal sewage, potable water, and industrial wastewater treatment projects, it addresses issues such as sludge accumulation at the tank bottom and surface scum buildup by enabling automated, continuous, and efficient cleaning operations. It serves as a core component for ensuring stable water quality in circular sedimentation tanks.
The equipment features a scientifically optimized, compact design. Its main components include a flow-stabilizing cylinder, a power collection assembly, a central support, a main bridge/walkway, sludge scraping and scum removal mechanisms, a drive unit, a traveling mechanism, and an electrical control system. The central support utilizes a specialized fixed mount and slewing bearing structure, capable of withstanding axial forces, radial forces, and overturning moments with exceptional stability. The slip-ring power collection assembly—comprising collector rings and brush holders—ensures continuous and stable power transmission during rotation. The dedicated scum removal mechanism consists of a scum scraper blade, a rake, and a discharge hopper, enabling comprehensive removal of floating debris. The main bridge connects the central support to the traveling end carriage and integrates a walkway and safety railings; it carries the sludge scraping and scum removal mechanisms underneath and is driven by the peripheral drive system to rotate the entire unit at a constant speed.
The equipment operates on a highly efficient principle: raw water flows out from the top of the central pier and is evenly distributed by the flow-stabilizing cylinder, moving radially toward the peripheral collection trough. As the flow velocity gradually decreases, suspended solids and sediment settle to the tank bottom. The unit continuously rotates around the central support, driving the scraping mechanism to collect settled sludge evenly into the central sludge collection trough, from where it is automatically discharged via hydrostatic pressure or sludge pumps. Simultaneously, the scum removal mechanism collects surface scum into the discharge hopper for removal. This enables simultaneous bottom sludge scraping and surface scum removal through a fully automated, closed-loop process requiring no manual intervention.
二、Product Advantages
1. Optimized Drive Structure for Stable and Durable Operation
The equipment features a newly optimized peripheral drive system characterized by high transmission efficiency and minimal power loss, all within a compact, aesthetically pleasing design. Options include imported or shaft-mounted gear reducers to suit various load conditions, ensuring smooth operation, low failure rates, and exceptional wear resistance; this significantly extends the equipment's service life and supports continuous, long-term operation.
2. High Processing Capacity with Superior Sludge and Scum Removal
Utilizing radial-flow uniform distribution principles and a comprehensive rotating scraper mechanism, the unit covers a large surface area and handles high water throughput. It efficiently captures settled sludge from the bottom and floating scum from the surface, ensuring thorough removal with no dead zones or residue. It effectively resolves issues such as sludge accumulation, floating scum, and water turbidity, guaranteeing stable effluent quality that meets standards.
3. Compact, Simple Structure for Convenient Operation and Maintenance
The equipment employs an integrated, modular design with a rational layout and a small footprint, eliminating the need for complex civil engineering structures and simplifying installation and commissioning. With a mature, stable mechanical structure, highly interchangeable components, and minimal potential failure points, it requires only routine inspections and maintenance. Operation is simple, maintenance costs are extremely low, and the system is suitable for unmanned, automated operation.
4. Dual-function operation with significant energy savings
The equipment simultaneously performs two processes—sludge scraping at the tank bottom and scum removal from the water surface—replacing multiple separate cleaning units and ensuring high equipment utilization. The peripheral drive system features low power requirements and minimal energy consumption; its steady, constant-speed rotation eliminates energy waste, offering outstanding energy efficiency compared to traditional sludge scrapers and excellent long-term cost-effectiveness.
5. High load-bearing capacity, suitable for complex operating conditions
The core central support utilizes a composite load-bearing structure capable of withstanding multidirectional forces. It offers superior resistance to overturning and impact, remaining stable despite fluctuations in water quality, flow rates, or load variations. The equipment operates without vibration or misalignment, making it suitable for routine operations in circular sedimentation tanks of all sizes—small, medium, and large.
三、Scope of Application
The Haipuou WBG-series peripheral-drive sludge scraper is highly adaptable and stable. Specifically designed for various circular radial-flow sedimentation tanks, it is widely used in municipal water supply, sewage treatment, and industrial environmental protection projects. Key application scenarios include:
1. Municipal Sewage Treatment: Suitable for sludge and scum removal in radial-flow primary and secondary sedimentation tanks at municipal and township sewage treatment plants. It ensures the stable operation of biochemical and sedimentation processes and serves as standard core equipment for municipal sewage facilities.
2. Waterworks Purification: Compatible with circular radial-flow sedimentation tanks in waterworks. It efficiently removes settled silt, impurities, and surface floating matter from raw water, reduces turbidity, and ensures the purified water meets quality standards.
3. Industrial Wastewater Treatment: Widely used in circular sedimentation tanks for industrial wastewater across sectors such as chemicals, printing and dyeing, papermaking, metallurgy, food processing, and pharmaceuticals. It efficiently handles suspended solids, settled sludge, and production-related scum, meeting requirements for compliant discharge and water recycling.
4. New and Retrofit Sewage Projects: Suitable for equipping new circular radial-flow sedimentation tanks (large, medium, or small) and for upgrading or retrofitting aging equipment. It offers exceptional versatility and can be customized to match specific tank dimensions and treatment capacities.
