Vacuum belt filter

Vacuum belt filter from KÖBO ECO>PROCESS GmbH for standard coolant filtration

The vacuum belt filter (VBF) is a fully automatic cooling lubricant filter that is continuously supplied with contaminated cooling lubricant from the production return flow and acts as a container to store the cooling lubricant for the entire circulation system . Filter/system pumps connected to the lower suction chamber generate a vacuum in the lower chamber and suck the cooling lubricant through the filter medium, cleaning it and making it available to the production supply again.

The filtered dirt cake is discharged discontinuously for chip disposal. During chip discharge, production is supplied with cooling lubricant via a separate regeneration tank.

Structure
  • Upper dirt chamber for collecting the cooling lubricant (CL) contaminated with dirt particles
  • Horizontal filter belt support to separate the upper dirt chamber from the lower filtrate suction chamber
  • Lower filtrate extraction chamber (vacuum chamber) for collecting the cleaned cooling lubricant with connection to the filter/system pump(s)
  • Filter medium: Circumferential filter tape or fiber fleece
  • Modular system: short assembly and set-up times
  • Fully automatic
  • Continuous operation (production supply during regeneration phase through separate regeneration tank)
  • Filtration by flowing the cooling lubricant through the filter medium (vacuum build-up in the lower filtrate extraction chamber if necessary)
  • Initiation of filter regeneration by vacuum measurement or time lapse
  • Fully automatic belt cleaning with brush or beater shaft and belt rinsing
  • Possible for nonwoven operation with take-up reel
  • Dirt deposits are avoided by flushing or designing the lower chamber as a channel system
  • machining processes with:
  • Cutting chips, fine and short
  • Sanding swarf and sanding sludge
  • Can also be used as a secondary filter/post-filter
  • Cleaning of cooling lubricants in machining processes such as turning, drilling, milling and certain grinding processes. Usually with endless nylon belt, optionally also in non-woven mode (if required)
  • Increased throughput due to possible negative pressure in the lower chamber
  • The VBF combines the functions of coolant supply and filtration
  • Continuous and fully automatic operation
  • Automatic belt cleaning with brush or beater shaft and belt rinsing
  • Filter fineness* [µm]: 120 - 30
  • Size of filter area [m²]: 2.0 - 45.0
  • Throughput* [l/min]: 500 - 20,000
  • Sizes: standard sizes from 3 to 24 m², larger sizes according to customer requirements, smaller sizes (0.7 - 1.4 m²) are only available for paper operation
