Title
(EN) DEVICE FOR MAKING OF POROUS CONCRETE
(FR) DISPOSITIF DE FABRICATION DE BETON POREUX
Abstract
(EN)
Device for making of porous concrete intended for casting of e.g. elements of buildings, by which mainly cement, water and a frothing agent are mixed at the same time causing air pores in the mixture to be clasted, consisting of a cylindrical mixing-tank (1) in which an impeller (3) is arranged with a rotation axis which coincides with the centre axis of the mixing-tank (1) and by which the impeller (3) includes blades (31) that extend helicoidally along the mixing tank (1) by which the helicoidally of each blade is less than 90o over the length of the impeller (3) and by which the blades (31) extend a bit against the centre axis of the impeller (3). Each blade (31) consists of two, in direction to the centre axis of the impeller (3), reciprocally flat strips (32), which incline against the envelope to the mixing tank (1) so that the front edge in the moving direction of the outer strip (32) is located next to the envelope. Wings (33) are arranged between the strips (32) in each blade which incline against the centre axis of the impeller (3).
(FR)
Dispositif de fabrication de béton poreux conçu pour couler par exemple des éléments de construction, dans lequel principalement du ciment, de l'eau et un agent moussant sont mélangés simultanément, créant des pores d'air dans le mélange à couler, composé d'un réservoir de mélange cylindrique (1) dans lequel est disposée une turbine (3) dont l'axe de rotation coïncide avec l'axe central du réservoir de mélange (1) et où la turbine (3) comporte des lames (31) s'étendant hélicoïdalement le long du réservoir de mélange (1), l'angle hélicoïdal de chaque lame étant inférieur à 90o sur toute la longueur de la turbine (3) et les lames (31) s'étendant un peu en direction de l'axe central de la turbine (3). Chaque lame (31) est formée de deux bandes (32) plates réciproquement en direction de l'axe central de la turbine (3) et se penchant contre l'enveloppe vers le réservoir de mélange (1) de telle manière que le bord frontal dans la direction d'avancement de la bande extérieure (32) est situé près de l'enveloppe. Des ailettes (33) sont disposées entre les bandes (32) dans chaque lame et s'inclinent en direction de l'axe central de la turbine (3).
