Embodiment Construction

[0025] figure 1A simplified diagram showing the drive of a device for mixing liquids according to the prior art. In this figure, the electromagnetic driver 1 is fixedly connected with the rigid frame frame 3 . Rigid plates 5 are connected and supported by one or more helical springs 4, which can be arranged both in parallel and in series, to ensure optimal support. A permanent magnet or magnetisable element 2 is connected to the plate 5 and is excited by the magnetic coupling of the electromagnet 1 such that the spring 4 is in an oscillating state. The plate 5 is supported by the spring 4 so that it can freely oscillate in the main direction. The main direction along the line 11 is defined by the force of the electromagnet 1 on the permanent magnet or the force of the magnetizable element 2 on the steel plate 5 . The shaft 6 connected to the steel plate then oscillates in the main direction 11 and can transmit the oscillations to the mixing elements fastened to the shaft 6 ...

Abstract

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 vibrateby 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 along 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.

Description

technical field [0001] The invention relates to a device for mixing liquids, liquids with gases or solids by means of vibrations. Background technique [0002] Known devices for mixing liquids by means of vibrations have a mass-spring system which is oscillated by an electromagnetic drive (also referred to as an electromagnet) and which is connected to the mixer plate by a shaft. The spring system is electromagnetically coupled to an electromagnet which is actuated with alternating current or current pulses and causes the mass-spring system to oscillate. The (vertical) deflection in the direction of the abutment force and repulsion force generated by the magnetic field to the spring system is thus transmitted via the drive shaft to the mixer plate in the mixing medium. In order to achieve the highest possible efficiency, the oscillating system must oscillate as close to its resonance as possible, since this minimizes the excitation force required by the drive. By judicious...
