一、Product Introduction
The Haipou Environmental Protection bridge-type sludge scraper (or sludge suction machine) is a fully automated, integrated sludge removal system specifically designed for horizontal-flow and inclined-tube sedimentation tanks. Widely used in waterworks, municipal sewage treatment plants, and industrial wastewater treatment projects, it serves as core specialized equipment for sludge removal and water quality stabilization. Featuring a lightweight truss structure that spans the tank, the system comprises a working bridge, a dual-side drive mechanism, an intelligent sludge suction system, an electrical control system, a siphon generator, and an optional scum skimming device. Its highly integrated design and logical layout allow it to adapt perfectly to the operating conditions of various rectangular sedimentation tanks.
The equipment supports three sludge removal modes—siphon suction, pump suction, and a hybrid pump-siphon mode—allowing for selection based on specific water quality and tank conditions. It utilizes a four-point support design to travel smoothly back and forth along rails on both sides of the tank, performing simultaneous travel and sludge suction. Automated reversal cycles, controlled by travel limits, ensure continuous extraction and discharge of settled sludge, effectively replacing manual cleaning and eliminating issues such as sludge accumulation and water quality deterioration. The main structure undergoes hot-dip galvanizing for corrosion protection, guaranteeing rust-free performance for five years, while all core components in contact with water are made of 304 stainless steel for superior corrosion and aging resistance. Combined with a precision drive mechanism and steel travel wheels, the unit offers stable, durable operation and is capable of continuous, fully automated 24-hour service.
二、Product Advantages
1. Three Sludge Removal Modes for Exceptional Operational Versatility
The equipment integrates three mainstream sludge removal technologies: siphon, pump-suction, and a hybrid pump-siphon mode. The siphon mode utilizes liquid level differences for automatic, energy-efficient, and quiet operation; the pump-suction mode handles high-concentration sludge with high discharge capacity; and the hybrid mode balances energy efficiency with high performance. This versatility allows for precise adaptation to various tank specifications and sludge concentrations, enabling a single unit to handle sludge removal across all types of sedimentation tank scenarios.
2. Lightweight, Corrosion-Resistant Structure for Extended Service Life
Featuring an optimized truss design, the unit is lighter than traditional equipment yet offers superior structural strength and stable load-bearing capacity. The main frame undergoes hot-dip galvanizing for long-lasting rust and corrosion resistance, ensuring a rust-free lifespan of at least five years. Components in direct contact with water and sludge are precision-crafted from 304 stainless steel, effectively resisting sewage corrosion, scaling, and abrasion, thereby significantly extending the equipment's overall service life.
3. Precision Drive Design for Smooth, Error-Free Operation
Equipped with a new, proprietary drive mechanism, the system eliminates common issues found in traditional sludge scrapers—such as asynchronous travel at both ends and significant alignment errors—ensuring precise positioning and smooth operation throughout the process. Steel travel wheels provide high wear resistance, pressure tolerance, and load-bearing capacity; they resist wear and derailment during continuous reciprocating operation, resulting in a very low failure rate and significantly enhanced operational reliability.
4. Fully automated and unattended operation with minimal O&M costs
Equipped with an intelligent electronic control system, the unit operates via fully automated round-trip movement, automatic start/stop, and cyclical sludge discharge, requiring no dedicated on-site personnel. It features low power requirements and energy consumption, minimal daily maintenance needs, and a scientifically optimized pump design that ensures smooth, jam-free operation. These attributes significantly reduce labor and energy costs, delivering outstanding long-term economic efficiency.
5. Thorough sludge removal preventing secondary accumulation
The equipment moves at a steady, uniform speed with precise control over the suction nozzle's distance from the tank floor, ensuring comprehensive sludge extraction with no dead zones. It rapidly clears settled sludge, effectively resolving issues such as sludge accumulation, floating sludge, and water turbidity; this ensures consistent effluent quality and enhances the operational efficiency of the entire water treatment system.
6. Convenient, safe installation suitable for retrofit projects
With a streamlined structure and simple installation and commissioning, the equipment is suitable for both new construction and retrofit sedimentation tank projects. It is equipped with comprehensive travel limiters and anti-derailment/anti-fall safety mechanisms to eliminate the risk of derailment or falling into the tank, ensuring high operational safety and suitability for long-term, continuous operation.
三、Scope of Application
Haipuou bridge-type sludge scraper is highly versatile and suitable for a wide range of scenarios; it serves as standard sludge removal equipment for various horizontal-flow and inclined-tube sedimentation tanks. Its core applications include:
1. Municipal Water Treatment Plants: Suitable for removing settled silt and impurities from horizontal-flow sedimentation tanks in waterworks. It effectively reduces water turbidity, ensures treated water meets quality standards, and integrates seamlessly with urban water supply treatment systems.
2. Municipal Wastewater Treatment Projects: Widely used in urban and township wastewater treatment plants for sludge suction and discharge in horizontal-flow primary and secondary sedimentation tanks. It resolves sludge accumulation issues and ensures the stable operation of wastewater treatment processes.
3. Industrial Wastewater Treatment Projects: Suitable for sedimentation tanks in industries such as chemicals, papermaking, printing and dyeing, food processing, and metallurgy. It efficiently removes industrial sludge and impurities, meeting requirements for industrial wastewater recycling and compliant discharge.
4. Inclined-Tube Sedimentation Tank Applications: Can be equipped with specialized sludge suction hangers and tank-bottom suction frames to handle sludge removal in various inclined-tube sedimentation tanks. It is compatible with diverse tank structures and suitable for both new installations and the upgrading/retrofitting of existing wastewater treatment facilities.
