Title: Positive displacement metering dispenser for casting resins - in which resin is supplied to a continuous mixing device for catalyst addition, etc.
Inventor: HAEUSER ERHARD
IPC: G01F11/02
Filed: 1991-08-22
Abstract: Process is for dosed and controlled delivery of casting resin from a supply intake, formed at its lower end as a pump barrel, into which a piston, moveable and supported within the supply intake, is introducible, being novel in that the piston is pushed through a stroke distance by displacement of resin from a submerged swept length in the barrel and that subsequently the piston, under displacement of a predetermined resin quantity, executes a delivery stroke. Pref., at the start of the dosing cycle, the piston is completely withdrawn from the barrel, to allow free entry of resin into the barrel. Piston moves downwards through a first stroke length which includes the distance swept within the pump bore. At the end of this stroke the barrel is sealed by the piston and the displaced resin forced via discharge line, valve, recycle line, and throttling valve back into the holding chamber. Pressure sensor detects the back-pressure produced in the resin flow by valve, thereby serving to indicate whether there is sufficient resin in the barrel and whether the piston has entered the barrel. Thereafter, the deliver stroke proceeds after the three-way valve has been switched, to feed the in-live mixer , by the controller acting on the pressure signals. Piston is driven by a motor, via connecting rod, and is guided within the cylindrical intake, by a slider-disk attached to the piston. The slider-disk has apertures to allow passage of fresh resin supplied via line. In a particular form, the appts. can be provided with a vacuum degassing facility in the resin intake/holding chamber. USE/ADVANTAGE - Metered pumping of resin components to a continuous mixing process, e.g., resin to be mixed with hardening catalyst in an in-line mixer
