Title: General purpose mixer with recycle - having central shaft with rotor at base and provision for static mixer elements
Inventor: SEIFERT WILHELM
IPC: B01J10/00
Filed: 1976-07-31
Abstract: Reactor mixer consists of a central vertical shaft, pref. circular into which is fed the raw material/mixture for processing. At the base of this is a rotary element, normally with an associated stator through which the material must pass and which subjects it to a mixing/shearing action. From this extends a radial passage outwards, using up and bringing the material back towards the inlet. This radial passage can contain various static mixing elements, baffles etc. to improve the blending/mixing effect. Product is removed by a circular outlet located close to the inlet. The amounts removed/recycled are governed by an adjustable slide close to the inlet. Used for various mixing and reaction processes (homogenising, emulsifying, stirring, dissolving, milling, wet milling, heating, cooling, gas injection, degassing etc.). The system permits the control of the amt. of recycle to give optimum quality and energy usage.
