Abstract
Abstract Lime, preferably as calcium oxide, is mixed with the contents of sumps, such as oil well sumps, and these generally have a pasty or plastic consistency. The calcium oxide reacts with the materials present and also dehydrates the contents of the sump, causing the sump contents to stiffen. This mixing is performed by a drag line scoop that carries calcium oxide through the sump contents, mixing and blending the oxide and contents as it moves because of the unique construction of the mixing scoop. Once the mixing and blending is complete and reaction of the calcium oxide and the contents is complete, the sump contents are dredged and deposited on high ground to dry by the combined action of sun and air. Drying periods may range from several days to several weeks and the material thereupon becomes a dry, hard and stable type of soil suitable for fill purposes and which, when neutralized with acid, also may be suitable for agricultural purposes.

Claim 1
Independent Claim
379 words
In combination with a sump of pasty material that has first and second oppositely disposed sides, a pile of powdered solid material at least partially in said sump adjacent said first side thereof, an apparatus for use in mixing said powdered solid material with said pasty material, said apparatus including: a. first and second scoops, each of said scoops including a pair of side walls, forward and rearward end walls connected to said pair of side walls, a top supported from said pair of side wall and forward and rearward end walls, a transverse blade that extends downwardly and forwardly from said rearward end wall, and a plurality of apertures defined in said forward end wall, pair of side walls and said top; b. first and second laterally spaced pulleys that are anchored at fixed positions adjacent said first side of said sump; c. first and second laterally spaced, power-operated winches located at fixed positions adjacent said second side of said sump, said first and second winches capable of being operated concurrently to rotate in opposite directions; d. a drag line that engages said first and second winches and extends across said sump to movably engage said first and second pulleys, said drag line including first and second reaches that have said first and second buckets interposed therein, with said winches when operated to rotate in opposite directions permitting one of said scoops to be moved upwardly on said pile and then moved towards said second side, with said scoop as it moves on said pile towards said second side having said blade thereof dig into said pile and direct solid material into said scoop, and said blade as said scoop moves towards said second side through said pasty material forcing said pasty material into said scoop whereupon it mixes with said powdered material in said scoop and the resulting mixture of said pasty material and powdered material being extruded outwardly from said scoop through said apertures, and as one of said first or second scoops moves towards said second side the other of said scoops moving towards said first side and said pile where it may be loaded with said powdered material to be subsequently mixed with said pasty material when it is moved towards said second side.
