BKW Kuma Automatic Filter Devices

Automatic Filter Devices are designed for an automated purification of cooling lubricants. They are used in:
• Honing, grinding and glass grinding machines
• Tempering plants
• Washing plants

Function

The soiled cooling lubricant is conveyed onto the non-woven filter lying in a cavity, via a liquid feed distributor. Owing to the gravitational force the coolant flows through the non-woven filter into a liquid container beneath the band filter. The dirt particles contained in the cooling lubricant are filtered out by the non-woven filter and accumulate in the form of a sludge cake on it. This causes a reduction of the permeability of the filter paper and, therefore, an increase of the liquid level above the filter cavity. As the liquid level increases, an adjustable float-type switch controls the continuous transport of the non-woven filter driven by an electric motor. This way, non-woven filter clogged with dirt particles is discharged automatically driven by the quantity and permeability of the dirt accumulations. The dirty non-woven filter is conveyed into a sludge box installed at the end of the Automatic Filter device and can be removed from there without affecting the filtration process in any way. A Magnetic Filter Roll installed upstream allows the extraction of any ferritic dirt particles already before introducing the liquid onto the band filter, leading to a considerable reduction of paper consumption.

Structure

• Solid steel plate design
• Closed non-woven storage box
• Endless wire mesh band serving as a support for the non-woven filter
• Discharge via the bottom side of the filter
• Helical gear motor or synchronous motor ensuring the drive
• Warning message: "non-woven lacking" (optional)
