Application Scenarios

Industrial Wastewater Treatment

Applicable to wastewater from machinery manufacturing (cutting fluid wastewater), metal processing (cooling water wastewater), food processing (fried oil wastewater), and petrochemical (oil refining wastewater) industries. It is mainly used in oil-water separation tanks, sedimentation tanks, and adjusting tanks to remove floating oil and light oil, reducing the oil content of incoming water for subsequent biochemical treatment (oil content ≤50 mg/L after treatment).

Oil Storage & Transportation Industry

Used in oil storage tanks, oil depots, and oil terminals. It can remove floating oil on the surface of tank cleaning wastewater and rainwater in the tank area, preventing oil from entering the sewage system and causing pipeline blockage or environmental pollution. It is also suitable for emergency oil removal in small oil spill accidents in oil tank areas.

Marine & Port Environmental Protection

Suitable for small and medium-sized oil spill treatment in ports, docks, and inland waterways (oil spill volume ≤50 m³). The 316L stainless steel version can resist seawater corrosion, and the flocked fiber belt can quickly absorb diesel, gasoline, and crude oil, reducing the impact of oil spills on aquatic ecosystems.

Cooling Water System

Used in open cooling water towers and circulating cooling water systems of power plants, chemical plants, and data centers. It removes oil leaked from equipment (such as pump seals) in the cooling water, preventing oil from adhering to the heat exchange surface and affecting heat exchange efficiency, and avoiding the growth of oil-decomposing bacteria causing biological fouling.

Municipal & Environmental Emergency

Applied to oil removal in municipal sewage treatment plants (grease trap auxiliary oil removal) and emergency treatment of oil spills in rivers, lakes, and reservoirs. It can be quickly deployed to the accident site, and the mobile version can realize on-site rapid oil removal, reducing environmental pollution.

Core Functions & Working Principle

Efficient Oil Absorption & Scraping

The flocked fiber belt has strong oil absorption capacity, and the precision scraper can completely scrape off the adsorbed oil, with an oil removal efficiency of ≥95% for floating oil with a viscosity of ≤100 cSt.

Continuous Automatic Operation

Driven by a frequency conversion motor, it can operate 24 hours a day continuously. The oil absorption belt speed can be adjusted (0.5-5 m/min) according to the oil content, realizing adaptive oil removal and saving energy.

Corrosion & Wear Resistance

The stainless steel main body and wear-resistant flocked fiber belt adapt to harsh working environments, reducing maintenance frequency and extending equipment service life.

Easy Operation & Monitoring

Equipped with a simple control panel, it supports manual/automatic switching. The optional liquid level sensor and oil content monitor can realize automatic start-stop and remote monitoring of oil removal effect.

Low Energy Consumption & Environmental Protection

The power of the main motor is only 0.37-2.2 kW, and the oil-absorbing belt can be reused after cleaning, reducing material consumption and operating costs. The collected oil can be recycled, realizing resource reuse.

Working Principle

The Belt Oil Skimmer adopts a "adsorption - scraping - collection" three-stage oil removal mechanism, and the specific working process is as follows:

Oil Absorption Stage

The lower part of the flocked fiber oil-absorbing belt is immersed in the water to be treated (immersion depth can be adjusted 5-50 mm). Due to the lipophilic and hydrophobic characteristics of the flocked fiber, the floating oil on the water surface is quickly adsorbed on the surface of the belt, while almost no water is absorbed.

Oil Scraping Stage

2.The oil-absorbing belt adsorbed with oil is driven by the motor to rotate upward. When passing through the precision scraper (the gap between the scraper and the belt is ≤0.1 mm), the oil on the belt is completely scraped off. The Teflon coating of the scraper ensures that the oil does not adhere to the scraper surface.

Oil Collection Stage

The scraped oil flows into the oil collection tank through the oil guide groove, and then is discharged to the oil storage barrel or oil-water separator through the oil discharge pipe for further treatment or recycling. The oil-absorbing belt after oil scraping continues to rotate and immerse in water to start the next cycle.

Adaptive Adjustment

The frequency conversion motor adjusts the rotation speed of the oil-absorbing belt according to the oil content (detected by the oil content sensor) or manually set parameters. When the oil content is high, the speed is increased to improve oil removal efficiency; when the oil content is low, the speed is reduced to save energy.

Installation & Maintenance Requirements

Site Requirements

The installation site should be flat and solid, with a bearing capacity ≥1.5 times the net weight of the equipment. For indoor installation, ensure good ventilation; for outdoor installation, configure rainproof and sunshade facilities. The distance from the equipment to the edge of the water tank/pool should be 300-500 mm, and a maintenance space of ≥600 mm should be reserved around the equipment.

Installation Position

The oil-absorbing belt should be aligned with the main floating oil area of the water surface. The immersion depth of the belt should be adjusted according to the oil layer thickness (generally 10-20 mm for thin oil layers, 30-50 mm for thick oil layers). The oil collection tank should be placed lower than the scraper to ensure smooth oil flow.

Power Supply Connection

The power supply voltage should be stable within ±5%, and an independent circuit breaker and grounding device should be configured (grounding resistance ≤4Ω). For outdoor or wet environments, use waterproof cables and connectors to meet the protection level requirements.

Commissioning

After installation, manually rotate the oil-absorbing belt to check for jamming; adjust the scraper gap to ensure that the oil is scraped clean without damaging the belt; test run for 2 hours, check the oil removal efficiency and equipment operation status, and adjust the belt speed according to the actual oil content.

Daily Maintenance

Check the oil level in the oil collection tank and empty it in time to avoid oil overflow; clean the surface of the oil-absorbing belt with a soft brush (for sticky oil) to prevent oil accumulation affecting oil absorption; check the tightness of the belt (adjustable via tensioning device if loose); record the equipment operation time and oil removal amount.

Weekly Maintenance

Inspect the scraper for wear (replace if the gap exceeds 0.2 mm); lubricate the motor bearing and transmission chain with lubricating oil (use lithium-based grease); clean the oil guide groove and oil collection tank to remove oil residues and impurities.

Monthly Maintenance

Check the oil-absorbing belt for wear, aging, or damage (replace if the oil absorption rate decreases by more than 30%); inspect the motor and reducer for abnormal noise or overheating; tighten the bolts of the main body and frame to prevent loosening caused by vibration.

Quarterly Maintenance

Disassemble the scraper and clean the sealing ring (replace if there is oil leakage); check the frequency converter and control panel for normal operation; test the oil removal efficiency with standard oil samples and adjust the scraper gap or belt speed if necessary.

Annual Maintenance

Replace the oil-absorbing belt (regardless of wear for safety); overhaul the motor and reducer (replace worn parts such as bearings and seals); perform anti-rust treatment on the stainless steel main body (polish and apply anti-rust oil for coastal or high-corrosion environments).
