Abstract (en)
[origin: WO2019234534A1] The invention relates to a device for mixing liquids and solids with liquids by means of vibration. A spring system (8, 8', 8''), which permits oscillation in one degree of freedom, is made to vibrate by means of an electromagnet (1), being magnetically coupled. A shaft (6) connected to the spring system (8, 8', 8'') transmits this unidirectional oscillation to a mixing member within the medium that is to be mixed. The spring system (8, 8', 8'') consists of flat spring elements (8, 8', 8'') made of spring steel or fiber-reinforced plastic and makes it possible to precisely set the vibration behavior by adapting the spring element clamped lengths. The design of the spring elements (8, 8', 8'') is set up so that in operation the loads on the spring elements (8, 8', 8'') are spread out and a long life is guaranteed even under high loads and cycles. The device is used for mixing volumes of up to 10,000 L and is operated at frequencies of up to 200 Hz and an amplitude of multiple millimeters.
