Coolant lubricant particle-floatation primary filter cartridges stand immediately upon sludge vessel

摘要

A particle-floatation filter (59) acts as a fine-filter for coolant lubricant and consists of: (i) a primary filter (4) with a filter cartridge (5); and (ii) a secondary treatment stage (7) using a pressure-belt filter (9), a sludge vessel (8), a vessel (39) for the arriving particles and liquid, and a vessel (53) for the clean liquid. The novelty is that: (a) the primary filter (4) and filter cartridges (5) stand immediately upon the sludge vessel (8); (b) the sludge vessel (8) stands immediately upon the secondary treatment (7) pressure-belt filter (9); (c) the pressure-belt filter (9) is secured immediately to a three-part vessel (22) serving as an intermediate reservoir.
