TH33631A - Self-cleaning reactor / mixer for high viscosity and sticky mixtures - Google Patents

Abstract

DC60 (31/03/40) This invention relates to a fully self-cleaning reactor/mixer with a very large free volume, kinematically self-cleaning, consisting of two or more parallel (2,2') shafts rotating in opposite directions, on which are axially overlapping helical agitators (3,3') with scrapers (4,4', 5,5') on the front and rear of the agitators, and an enclosed body (1). Since all the scrapers (4,4') on the upstream side of the agitators (3,3') convey the associated material outwards, and all the agitators (5,5') on the downstream side of the agitators convey the material inwards, axial conveyance is achieved. This invention relates to a fully self-cleaning reactor/mixer with a very large free volume. A kinematic self-cleaning device consisting of two or more parallel shafts (2,2') rotating in opposite directions, on which are axially staggered helical agitators (3,3') with scrapers (4,4', 5,5') on the front and rear of the agitators, and an enclosed body (1). Since all the scrapers (4,4') on the upstream side of the agitators (3,3') convey the associated material outwards, and all the agitators (5,5') on the downstream side of the agitators convey the material inwards, axial conveyance is achieved.

Claims (5)

1. A mixer/reactor consisting of two or more parallel shafts (2,2') rotating in opposite directions, and on these shafts are axially overlapping helical agitators (3,3') with scrapers (4,4',5,5') on the front and rear of the agitators (3,3'), and a surrounding tank (1) with inlet (7) and outlet (9), and possibly an optional steam opening (8), where the scraper (4,4') on the front of the agitators (3,3') at the upstream end conveys all out, and the scraper (5,5') on the front of the agitators (3,3') at the downstream end conveys all in, and all surfaces of the scrapers (4,4',5,5') and agitators (3,3') are thoroughly kinetic cleaned. 2. The mixer/reactor, as defined in Reputation 1, is characterized by the edges of all cross-sections of the scraper (4,4',5,5') and the agitator (3,3') being epicycloidal or concentric circles around the center of rotation in any geometric cross-section radially through the mixer. 3. A mixer/reactor, as defined in claim 1 or 2, which is characterized by having only one (3,3') agitator blade mounted in each radial geometric cross-section on each (2,2') shaft. 4. The mixer/reactor, as defined in claim 3, which is characterized by toothed discs (80 and 80') that clean each other's circumference, is arranged at one or both ends of the shaft (2,2') along the last impeller (3,3') in the axial direction on each shaft. 5. A mixer/reactor as defined in any one of Requisitions 1 through 4, which is characterized by an inward conveying scraper (5,5') and an outward conveying scraper (4,4') connected to each other at the surface of the ends of those scrapers.
