Hydro excavation vacuum apparatus
A hydro excavation vacuum apparatus for excavating earthen material comprising: a wand for directing pressurized water toward earthen material to cut the earthen material at an excavation site; a vacuum system for removing cut earthen material and water from the excavation site in an airstream; a separation vessel for removing cut earthen material and water from the airstream; an airlock that receives material from the separation vessel and discharges the material through an airlock outlet; and a dewatering system for separating water from cut earthen material discharged from the airlock outlet, the dewatering system comprising: a pre screen that receives material from the outlet of the airlock, the pre-screen having openings for separating material from the separation vessel by size; and a vibratory screen for separating material that passes through the pre-screen by size, the vibratory screen having openings sized smaller than the openings of the pre-screen. lomoOQQ
