Abstract:
This invention is a low pressure, steady volume supply static mixer manifold for a high pressure pump. The design comprises an internal diffuser cylindrical tube inside an external rectangular tube in which static mixing occurs. Capped at one end, the internal diffuser pipe, with flow coming from the opposite side, allows for one flow direction diffused into the outer rectangular tube that then allows for constant bidirectional flow at a constant pressure throughout. The flow of slurry components between the cylindrical tube and the rectangular tube supports static mixing in part by creating alternating flow pressures between mixing ports (allowing flow of slurry components from the cylindrical tube) and the exit ports based on the different geometries of the cylindrical tube and rectangular tube. The combination of flow and pressure exiting the cylindrical tube through the mixing ports, at an angle to the bottom corners of the outer rectangular tube, creates a natural agitation of the slurry components. The cutouts in the inner tube are sized and spaced for providing the proper flow, mix, and pressure to each exit port.
