Patent Number: 6,305,835

Title: Apparatus for handling and preparing fluids

Abstract: Apparatus and processes are provided for handling fluids in numerous industrial applications. Materials addition devices, including venturi hoppers, and other eductor assemblies, are joined in compact, horizontal, and/or vertical configurations, with one or more shearing devices, including, high and low velocity shearing devices individually, as well as, a combination high and low velocity shearing device. Pipe and valve configuration allow several alternate paths through or around such assemblies and devices, in alternate directions, including the option to backflow through the high velocity shearing device for the removal of obstructions. In the high velocity shearing devices provided, a special jet insert is provided, along with jet insert installation related apparatus, by which the jet insert is easily retained in, and removed from, the piping in the high velocity shearing device. Various inlets into the materials addition devices, either singularly, or in combination allow optional paths for the entry of bulk materials, as well as, powdered polymers, liquid chemicals, and other materials, with a special tangential inlet used in some cases to work in combination with other inlets, to prevent vacuum dead spots during the process of introducing materials through inlet paths other than the traditional hopper throat. Also provided is a detachable side plate adjacent the mixing chamber of the venturi hopper and/or eductor assemblies which, when removed, allows an additional port for the entry of bulk materials, and also allows quick inspection, servicing and/or removal of the venturi jet.
