Title: Innovations by John J Walsh
Introduction
John J Walsh is a notable inventor based in Shoreview, MN (US). He has made significant contributions to the field of polymer processing, holding two patents that showcase his innovative approach to technology.
Latest Patents
One of his latest patents is a fluid bed cooling system for polymer processing. This system is designed for the solid phase polymerization of polymers. In this system, cold amorphous polymer is introduced to a crystallizer and heated to crystallize the polymer. The crystallized polymer is then discharged to a reactor to achieve polymerization. The hot polymer product from the reactor is subsequently sent to a fluid bed cooler for cooling. The cooler features an inlet for the hot polymer and an inlet for the cooling gas. After contact with the gas, the cooled polymer and heated gas are discharged from the cooler. The design includes a bed portion through which the polymer moves while in contact with the cooling gas, along with an upper chamber that collects the heated gas. The temperature of the polymer gradually decreases from the inlet to the discharge location. The gas in the upper chamber is hotter near the inlet for the hot polymer than near the discharge location for the cooled polymer. The upper chamber is equipped with at least two outlets, and a weir baffle separates the zone containing hotter gas from the rest of the chamber. The hotter gas is then discharged to the reactor through an outlet that communicates with the upper chamber zone.
