Waste liquid collecting device for machining

The invention discloses a machining waste liquid collecting device which comprises a collecting box body, a liquid inlet is formed in the top of the collecting box body, a partition plate is arranged at the lower end in the collecting box body, a motor is installed at the bottom of the partition plate, and a rotating disc driven by the motor to rotate is arranged at the top of the partition plate. A filter cartridge is mounted at the top of the rotating disc, a vertical rod is arranged in the center of the top of the rotating disc, an upper dispersing frame and a lower dispersing frame are arranged at the upper end and the lower end of the vertical rod respectively, movable assemblies are connected between the upper dispersing frame and the vertical rod and between the lower dispersing frame and the vertical rod, and liquid outlets are formed in the two sides of the partition plate. The waste liquid collecting device for machining can play a role in uniformly dispersing waste liquid, so that the waste liquid
