Picket scraper ESMIL – the optimal solution for thickening various types of sludge and suspensions. The use of Esmil picket scraper in radial thickeners significantly reduces costs related to sludge transportation, stabilization, and dewatering.
- Highly efficient device for collecting sludge from the bottom of sedimentation tanks
- High performance capacity
- Durable construction using corrosion-resistant materials
- Low operating costs
- Available in various sizes and configurations
Purpose of ESMIL Picket Scrapers
- Wastewater treatment plants
- Industrial facilities
- Water treatment plants
Efficiency, reliability, safety
Advantages of ESMIL Picket Scrapers
- Eliminates the need for an expensive bridge drive unit or track cleaner.
- No slip rings installation is required.
- Offers excellent corrosion resistance and enhanced strength, thanks to the use of stainless steel and aluminum materials capable of withstanding substantial loads.
- Features a diametral bridge structure, enabling visual monitoring of the sedimentation tank’s operation.
- Ensures safe personnel movement with an anti-slip “lentil” walkway surface and lower barriers on the handrail posts to prevent foot slippage.
- Integrated bridge lighting provides safe access during evening and nighttime operations.
- Equipped with a radial thrust bearing on the thickener’s central drive that requires no adjustments and supports heavy loads.
- Includes a bearing lubrication unit that allows servicing directly from the bridge without halting or dismantling the drive unit.
- Scraper blades are designed with a metal frame and a replaceable rubber strip, which efficiently cleans the sedimentation tank bottom and can be replaced cost-effectively after wear.
- A picket scraper structure in the gravity thickener improves sludge thickening by allowing excess water to drain efficiently from all sludge layers.
- Features a control cabinet with frequency converters to adjust scraper operating speed as needed. Siemens controllers in the cabinet ensure process management and protect electric drives and components from overload. The control cabinet can be installed either on the bridge or indoors near the scraper.
- Supplied in large modular components for quick assembly, minimizing labor requirements and significantly reducing installation time and the need for expensive specialized equipment.
