Abstract
A generally cylindrical mixing tank for oil well drilling mud circulates the mud passing out of a set of urethane nozzles about an elliptical path in the tank, which is coated internally with urethane thereby to provide a long lasting mixer in the presence of the abrasive drilling mud. New ingredients are entered into the tank directly from bags as they are passed over a cutter knife and across an entry grillwork platform. Water may be added for proper viscosity. The nozzles, by aid of a circulating pump taking mud from the tank, cause the mud to flow in a generally rotary path inside the tank and a set of knives is placed in this path to slice up any lumps or chunks of mud that may form.
Claims8
A mixer for preparing drilling mud at a desired viscosity, comprising in combination,
- a generally cylindrical tank,
- a set of nozzles located axially along the tank about the internal periphery disposed to direct materials in a rotary flow pathway about the interior circumference of the tank,
- path deflector means shaping the internal tank periphery to direct the rotary flow path into an elliptical orbit substantially symmetrical about the tank axis,
- material input means for introducing drilling mud ingredients into the tank for mixing into the rotary flow pathway before encountering the nozzles,
- means for introducing liquids into the tank to effect a change of drilling mud viscosity, and
- means for removing drilling mud from a position near the internal periphery of said tank to circulate back through said nozzles.
