Product Specifications

Technical details and manufacturing context for Skimming Drum/Belt

Definition

A skimming drum or belt is the key operational component of an oil skimmer system. It is a rotating drum or continuous belt, typically made of oleophilic (oil-attracting) materials, that is partially submerged in or passes over the surface of contaminated water. As it rotates, it attracts and adheres floating oils, fats, and greases. These contaminants are then scraped or wiped off the component's surface into a collection vessel, effectively separating them from the water. The component is available in various configurations, with belt widths ranging from 50 to 300 mm, belt lengths from 500 to 3000 mm, and belt thicknesses from 1.5 to 3.0 mm. Drum diameters range from 50 to 200 mm, and drum widths from 60 to 320 mm. The oil removal capacity is typically 5 to 50 liters per hour, depending on belt speed and oil viscosity. Belt speed can be adjusted between 0.5 and 2.0 meters per minute. The operating temperature range is -20 to 80 degrees Celsius. Material hardness is typically 60 to 70 Shore A (ASTM D2240), and tensile strength is 10 to 20 MPa (ISO 37). The complete drum and belt assembly weighs between 2 and 15 kg. If integrated with motor and electrical components, the IP rating is typically IP54 to IP65 (IEC 60529). Materials commonly used include stainless steel, polypropylene, and specialty oleophilic polymers such as modified polyurethane. These components are used in industrial applications where floating oils and greases must be removed from process water, coolant, or wastewater. Selection of the appropriate drum or belt depends on factors such as tank opening size, required oil removal rate, and the physical and chemical properties of the liquid. It is essential to verify model-specific values and standards with the legal manufacturer or supplier before procurement.

Working Principle

The component operates on an adsorption and mechanical removal principle. Its oleophilic surface preferentially attracts and adheres hydrocarbon-based contaminants (oils, greases) over water. As the drum or belt rotates through or across the liquid surface, it picks up these floating substances. A wiper blade or scraper then mechanically removes the accumulated oil from the component, allowing it to be collected for disposal or recycling, while the cleaned component returns to the liquid to continue the skimming cycle.

Frequently Asked Questions

What materials are available for skimming drums/belts?

Common materials include stainless steel, polypropylene, and specialty oleophilic polymers such as modified polyurethane. The choice depends on the application and chemical compatibility.

How do I select the correct belt width and length?

Belt width and length should be selected based on the skimmer capacity and tank opening. Typical ranges are 50-300 mm for width and 500-3000 mm for length. Confirm with the manufacturer for your specific setup.

What is the typical oil removal capacity?

Oil removal capacity ranges from 5 to 50 liters per hour, depending on belt speed and oil viscosity. Higher speeds increase pickup but reduce dwell time.

What are the operating temperature limits?

The operating temperature range is -20 to 80 degrees Celsius. Exceeding this range may degrade the belt material.
