Title: Innovative Contributions of David A. Prucha in Slurry Mixing Technology

Introduction

David A. Prucha, a prominent inventor based in Duncan, OK, has made significant strides in the field of slurry mixing technology. With a total of five patents to his name, his innovations particularly focus on enhancing the efficiency and effectiveness of mixing high-density and high-viscosity fracturing fluid slurries, which are vital in various industrial applications.

Latest Patents

Among his recent patents, David's design of a slurry mixing apparatus stands out as a remarkable advancement. This apparatus is specifically tailored for mixing slurries that contain a large proportion of proppant material. The innovative mixing tub features a generally round horizontal cross-sectional shape, and employs a large, low-speed rotating agitator. This unique agitator creates a radially inwardly rolling toroidal-shaped slurry flow zone adjacent to the upper surface of the slurry.

In this design, a stream of clean fracturing fluid is introduced near the center of the toroidal flow zone, facilitating efficient contact between the dry proppant material and the clean fluid. Additionally, foraminous baffles, made from expanded metal sheets, are strategically placed within the tub to minimize the rotational motion of the slurry, ensuring that proppant dropout is avoided. To effectively manage the slurry, a double suction vertical sump pump is utilized to pump the mixture from the tub, enhancing overall operational efficiency.
