Industrial oil skimming is a vital process in the efficient and cost effective treatment of fluids such as CNC machine coolant. The waste oil must first be removed and separated before these fluids are recycled or discharged.
This is where industrial oil skimmers come into play. They are mechanical devices operated by pumps or motors that effectively remove tramp oil from your industrial fluids. By automating the initial stages of the treatment process, industrial oil skimmers promote longevity and enhance the efficiency of your fluid systems.
Let’s explore these categories and learn about the different types of oil skimmers available, along with their functionalities and applications.
Industrial Oil Skimming
Industrial oil skimmers mainly utilize a motor-driven circulation of skimming across the surface of the used coolant. The skimming media, which can take the form of tubes, belts, discs, or drums, collects the waste oil and transports it to a collection vessel. While the methodology is similar among these skimming media, their proficiency may vary in different situations.
Therefore, it is crucial to choose the appropriate method that aligns with your specific application requirements.
Belt skimmers feature a revolving belt made from either polyurethane or stainless steel. The choice mainly depends on the temperature of the fluid. Stainless Steel belts can withstand higher temperatures. The belt rotates around a submerged pulley in a fixed path. It consistently picks up floating surface oil upon contact. The oil adheres to the belt and directs to a scraper. This scraper dispenses the oil waste into a trough or diverter leading to an oil storage tank. Belt skimmers excel in areas with narrow, deep pits where lateral space is limited. However, they are susceptible to debris interfering with the oil collection by forming a dam around the fixed path. Monitoring is useful to ensure debris does not obstruct the oil from reaching the belt.
Disk skimmers are stationary devices that submerge the lower edge of a revolving disk to collect oil from the water’s surface. The oil is gathered with wiper blades and directed into an oil storage tank. These fixed skimmers are highly effective in capturing more oil than water. Nonetheless, if the fluid level fails to cover at least half of the disk’s surface, the pickup rate decreases. This renders disk skimmers less efficient in applications with fluctuating water or coolant levels. Keep in mind that they do work well with chips and fine debris.
Tube skimmers employ a free floating tube with a metal washer to keep it submerged. It continuously traverses the water surface. The tube material attracts to floating tramp oil, which accumulates on the tube’s exterior. The oil-covered tube is then pulled through a set of scrapers, transferring the oil into a collection tank. The clean tube returns to the tramp oil to collect more waste in a continuous cycle. Tube skimmers offer versatility and easy maintenance, with the ability to handle water level fluctuations without any submerged mechanical parts. They function seamlessly as the floating tube design allows it to navigate around coolant debris effortlessly.
The Z17 Coalescer is a recommended choice for individual sumps that operate day and night. Even when the machine’s pump is off, the tramp oil is removed, and the sump circulates. The Z17 Coalescer also has an optional attachment with a floating device called a weir. This effectively removes floating oil and other materials on the surface of the sumps. As the oil floats over a lip, it enters a trough. Then it is transferred to a storage tank for recycling or disposal. This gravity-fed system ensures a continuous flow of oil removal. Weir skimmers offer versatility in floating oil and material removal. Although, keep in mind that they pick up more coolant compared to other oil skimming options.
