Machining cutting water filtering device

The invention relates to a machining cutting water filtering device which effectively solves the problems that cutting fluid is low in filtering speed and prone to blockage, and filter cloth is frequently replaced. According to the technical scheme, the device comprises a shell, a water inlet pipe is arranged above the shell, a water outlet pipe is arranged below the shell, a filter body is arranged in the shell and comprises a horizontally-arranged top plate, and a bottom plate is arranged below the top plate in parallel; a water inlet is formed in the middle of the top plate, multiple first rotating shafts and second rotating shafts are circumferentially and evenly distributed between the top plate and the bottom plate, the second rotating shafts are located on the inner sides of the first rotating shafts, and the lower ends of the first rotating shafts penetrate through the bottom plate and are provided with first gears; a vertical filter screen is fixed on each first rotating shaft; the lower end of the second rotating shaft penetrates through the bottom plate and is provided with a second gear; a vertical separation blade is fixed on each second rotating shaft; and the plurality of filter screens and the plurality of separation blades can form a polygonal enclosure in an enclosing manner. Rapid screen cleaning is achieved, and meanwhile the filtering effect and the net cleaning efficiency are improved through centrifugal force.
