China-Made Hydraulic Reciprocating Sludge Scraper System for Rectangular Wastewater Tanks


Why Choose Us?

  1. 10+ Years of Expertise: Specialized in wastewater and sludge treatment solutions.

  2. German Technology Integration: Enhanced product performance and reliability surpassing industry standards.

  3. Premium Components: Only high-quality parts from trusted suppliers.

  4. In-House R&D & Manufacturing: Full control over design, production, and quality assurance.


Product Overview

The hydraulic reciprocating sludge scraper is an advanced system designed for continuous sludge transport and concentration in rectangular tanks. As a fourth-generation innovation evolving from cable-drag, bridge-drive, and chain-type scrapers, it offers minimal moving parts, low maintenance, high reliability, and integrated sludge thickening.

Applications

Ideal for rectangular sedimentation tanks in:

  • Municipal wastewater treatment plants

  • Industrial wastewater processing facilities

  • Sludge thickening and concentration operations


Structure & Working Principle

The system comprises a hydraulic power unit, push rod system, and wedge-shaped scrapers with diagonal braces.

Operational Process:

  1. The hydraulic cylinder drives a tripod mechanism to convert vertical motion into horizontal movement.

  2. Wedge scrapers reciprocate at the tank bottom with a stroke exceeding individual scraper spacing.

  3. During forward motion, sludge is pushed toward the collection ditch; during retreat, the scraper’s acute angle prevents backward sludge movement.

  4. Rapid retreat generates negative pressure, maintaining sludge layer inertia and ensuring continuous forward transport.

  5. The reciprocating action simultaneously thickens sludge (up to 3% concentration), reducing water and energy consumption.


Key Features

  1. Minimal Moving Parts: Reduced maintenance and enhanced durability.

  2. Continuous Sludge Transport: Efficient and uninterrupted operation.

  3. High Reliability: Robust design ensures long-term stability.

  4. Retrofit Compatibility: Suitable for existing rectangular sedimentation tanks.

  5. Easy Installation: Simplified integration with minimal modifications.

  6. Sludge Thickening Function: Increases concentration for reduced downstream processing load.

  7. Automated Control: PLC-based system for precise operation and monitoring.


Ideal For:
Upgrades of traditional rectangular tanks, new installations requiring efficient sludge removal and concentration, and projects prioritizing low operational maintenance.
