ABSTRACT:
A mud cleaning apparatus is set forth and has an upstanding cylindrical housing supported by a frame work with legs. There is a mud inlet line at the top of the housing. Centrally, a motor drives a drive shaft extending vertically in the housing and supporting cascaded circular screens which are rotated. Each screen has mesh openings to remove particles of particular size and mud flows through that screen into a funnel there below and is directed by the funnel into the next screen. Typically, three screens and three funnels are included wherein the bottom funnel connects with an outlet mud line to remove the clean mud. Trash removed from mud flow collects on the screens which are rotated, and such motion couple with vibration imparted to the screens causes the trash to migrate across the screens for ejection from the screens and accumulation in the bottom of the cylindrical housing and removal on a conveyor system.
