Method for removal of fluidized bed particles from extruded polymeric products processed therein
Abstract
Abstract IN PROCESSING, I.E., HEATING, COOLING, OR VULCANIZING, ESTRUDED POLYMERIC PRODUCTS IN FLUIDIZED BEDS, PARTICLES FROM THE BED STICK TO THE SURFACE OF THE PRODUCT. THESE PARTICLES CAUSE PROBLEMS IN SUBSEQUENT HANDLING AND FINISHING. PRESENT METHOD OF REMOVING THESE ADHERED PARTICLES INCLLUDE AIR BLASTING, RUBBING, AND BRUSHING THE SURFACE; RUBBING AND BRUSHING DAMAGE THE PRDUCT''S SURFACE WHEREAS AIR IS RATHER INEFFICIENT AND CAUSES CONTAMINATION OF THE BED. THIS INVENTION PROVIDES AN EFFICIENT PROCESS FOR REMOVING THE PARTICLES AND THAT DOES NOT DAMAGE THE SURFACE OT THE PRODUCT OF AN ELECTRIC FLUID SUCH AS AIR AND 25* TO 30* A STREAM OF AN ELASTIC FLUID SUCH AS AIR AND FLUIDIZED BED PARTICLES AGAINST THE SURFACE OF THE ONCOMING EXTRUDED PRODUCT.
