Note: Tank edge depth H is generally 1-4.5m. Specific dimensions like D2, B, B1 depend on civil engineering requirements.
Advanced Features
Logarithmic Spiral Scraper Design: Scientifically engineered scraper boards with logarithmic spiral geometry ensure uniform force distribution for complete sludge removal and exceptional scraping efficiency.
Dual Safety Protection System: Auto-yielding scraper mechanism prevents rigid collisions with obstacles, combined with torque protection in the drive unit for comprehensive equipment safety.
Optimized Hinged Structure: Newly designed hinged configuration improves scraper load-bearing capacity while reducing required operating power for lower long-term running costs.
Compact Drive System: Advanced shaft-mounted reducer eliminates traditional coupling requirements, resulting in simplified installation and maintenance with highly compact design.
Frequently Asked Questions
Will the scraper break if there are large rocks or debris at the bottom of the sedimentation tank?
No, it will not. The equipment features an auto-yielding function that allows the scraper to automatically adjust and bypass large obstacles. Additionally, the drive unit includes an over-torque protection device that activates immediately if resistance exceeds safe limits, ensuring the machine remains undamaged.
What shape of tanks is this equipment designed for?
The ZBGN Peripheral Drive Bridge Mud Scraper is specifically engineered for circular sedimentation tanks in wastewater treatment plants.
Is there any difference when using this machine in a primary settling tank versus a secondary settling tank?
Yes. Due to variations in sludge specific gravity and settling characteristics between primary and secondary tanks, the equipment operates at different speeds and requires different motor powers. Primary tanks typically operate at 3 m/min outer edge linear speed, while secondary tanks use 1.8 m/min, with corresponding differences in drive power requirements.
