Products Description
The Municipal Sewage Sludge Scraper is core special equipment for urban sewage sedimentation tanks. It falls into two categories: central drive and peripheral drive, and is compatible with large-scale radial-flow primary and secondary clarifiers in municipal wastewater plants. Driven by the drive system, the truss rotates slowly. Sludge scrapers at the tank bottom gather settled sludge and push it toward the central sludge hopper. A matched scum skimming device removes floating oil and scum on the water surface. The whole machine is fabricated from anti-corrosion carbon steel and stainless steel to resist corrosion from municipal sewage. It supports round-the-clock automatic operation without workers entering tanks for sludge cleaning, continuously completing mud-water separation and stabilizing water purification quality to meet the demands of large-scale, non-stop urban sewage treatment.
Process Technology
Integrated Welding
Main load-bearing components adopt an integrated welding process with uniform, firm weld seams and evenly distributed overall structural strength.
Precision Assembly
Transmission components are assembled with high precision to maintain reasonable transmission clearances, enabling smooth operation without jamming or abnormal noise.
Anti-Corrosion Coating
Metal components submerged in water undergo multiple anti-corrosion coating procedures, significantly boosting water and corrosion resistance.
Sealing Protection
Multiple sealing processes are applied to power connection joints to block sewage infiltration and protect internal core components.
Product Structure
It bears the overall weight of the equipment and travels smoothly along rails on the tank top, ensuring the whole machine follows an accurate, offset-free travel path.
It connects travel structures at both ends and carries sludge scraping components, acting as the core load-bearing member that transmits power for sludge scraping operations.
It operates in direct contact with the tank bottom, gradually gathering and pushing settled sludge to complete the core tank-bottom sludge removal process.
Installed on the water surface, it moves synchronously with the equipment and collects floating scum, pushing it uniformly to the designated scum discharge position.
It supplies stable power for the whole machine' s travel and sludge scraping movements, coordinating all components to operate in line with preset rhythms.
Functional Features
Complete Sludge Scraping
Sludge scrapers move closely along the curved tank bottom to minimize residual sludge and prevent sludge caking and accumulation.
Full Floating Scum Collection
Floating scum on the water surface is collected synchronously during travel without extra manual cleaning, keeping the tank surface clean of floating scum.
Overload Protection
A built-in mechanical overload protection structure triggers automatically when sudden heavy resistance occurs to avoid component damage.
Operation Instructions
Pre-Startup Inspection
Before activation, clear debris around the equipment' s travel path and confirm all components are in normal condition before starting the machine.
No-Load Trial Operation
For the first startup, conduct a short no-load trial run. Confirm no abnormal noise during travel before switching to formal sludge-bearing operation.
Operational Inspection
Conduct periodic observations of the equipment' s travel status during daily operation. Shut down the machine promptly to troubleshoot hidden dangers if abnormalities are detected.
Post-Operation Parking
Upon completion of work, park the equipment at the designated safe area, cut off the main power supply, and clean the surrounding area.
FAQ
Q: Will the Municipal Sewage Sludge Scraper agitate sewage at the tank bottom during operation?
A: The equipment runs at an extremely low rotational speed. Scrapers slide smoothly against the tank bottom to push sludge without stirring settled sediment, maintaining clear tank water.
Q: Can the sludge scraper thoroughly clean floating debris on the water surface?
A: The equipment is fitted with a matched scum skimming structure. It gathers floating scum and foam on the water surface during operation and collects them uniformly for discharge to purify the tank water surface.
Q: Can the equipment operate normally during rainy seasons when sewage contains increased impurities?
A: The Municipal Sewage Sludge Scraper adapts to municipal sewage environments with high impurity loads. Scrapers push sludge smoothly without frequent jamming by impurities, supporting stable and continuous operation.
