Large discharge vacuum filter device solves the filtering problem of large vacuum coolant in cutting and grinding process. It has large flow, high efficiency and is reliable. If you use it with chip conveyors, the effect would be better. Its main principle is: most dirty fluid and chips are discharged by chip conveyor firstly, and then a little tiny chips and dirty coolant enter into filtering tank. When chips accumulate and reach a certain thickness on the filter paper in vacuum chamber, filtering resistance will be increased. Meanwhile the pressure of pump inlet will be decreased. It causes negative value increased in vacuum chamber, when it reaches a preset value, dirty paper will remove automatically and cleaning paper covers wedge-shaped filtering screen again. The accumulations and dirty paper are discharged into dirt collecting box
