Mixing device - with two tubular membranes in two chambers alternately oscillated by compressed air admission

A liquid mixing device consists of two tubular chambers which are sepd from each other by an annular disc. Each chamber is lined with a tubular membrane, amde of elastic material, which rests at a perforated tubular support so that each membrane can be deflected inward in turn by the admission of a...

Summary:A liquid mixing device consists of two tubular chambers which are sepd from each other by an annular disc. Each chamber is lined with a tubular membrane, amde of elastic material, which rests at a perforated tubular support so that each membrane can be deflected inward in turn by the admission of a pressurised medium. Used in cleaning of machine parts, preparation of material to be transported in mines, mixing of pulps dispersions and degreasing in the chemical industry, wet treatment of leather and textiles. This ensures that the membranes oscillate mainly in the fundamental mode without higher harmonics. This improves the mixing of efficiency and prevents clogging of the perforations. L'invention concerne le traitement de matériaux ou de produits dans un courant de liquide. Le dispositif faisant l'objet de l'invention est caractérisé en ce que dans chacune des cavités 8 délimitées par la membrane 5 et le corps de la chambre tubulaire 2 est monté, coaxialement à celui-ci un élément d'appui perforé fixe et rigide 10 placé à une certaine distance de paroi de ladite chambre de manière qu'en l'absence de fluide gazeux dans ladite cavité, la membrane 5 vienne s'appliquer sur l'élément d'appui perforé 10. L'invention peut être utilisée notamment dans l'industrie minière, par exemple pour l'enrichissement des minéraux utiles, dans l'industrie chimique, par exemple pour la formation de suspensions, etc
