Definitions

  • the invention relates to a device for mixing liquids, liquids with gases or solids by vibration.
  • Known devices for mixing liquids by vibration have a mass-spring system which is caused to vibrate by an electromagnetic drive (hereinafter referred to as an electromagnet) and which is connected to a mixer plate by a shaft.
  • the spring system is electromagnetically coupled to the electromagnet, which is controlled with an alternating current or current pulses and causes the mass-spring system to oscillate.
  • the resulting (vertical) deflections in the direction of the impact and repulsion force of the magnetic field on the spring system are transferred to the mixer plate in the mixed medium by a drive shaft.
  • the oscillating system In order to achieve the highest possible efficiency, the oscillating system must oscillate as much as possible in its resonance, as this minimizes the required excitation force of the drive. This resonant frequency can be changed and optimized for the respective application by skillfully designing the spring elements of the mass and the damping values.
  • Such a system is known from the prior art under the designations vibro mixer and vibration mixer drive and is, for example, in CH289065 disclosed.
  • An example from industry is the vibro mixer under the name FUNDAMIXO from DrM Dr. called Müller AG.
  • vibro mixers of this type are used at an oscillating frequency of 50-100Hz and a Operated amplitude of 1-5mm.
  • Mixing elements which will not be discussed in detail here, are designed for unidirectional oscillating movement and achieve a comparable mixing performance to conventional rotary stirrers.
  • the spring system of such a vibro mixer usually consists of one or more spiral springs.
  • the springs mostly made of spring steel, withstand the constant changing load and are fixed to a spring force due to their geometric dimensions. This can be adjusted by changing the prestressing of the springs, which is associated with a great deal of effort, particularly when there are a large number of spiral springs.
  • the resonant frequency of the spring system is determined by the mass and the damping of the system and can therefore only be changed by replacing the springs or expanding the spring assembly. If there are several springs in the system, the spring forces can vary with several springs in the system due to the smallest differences in the material, temperature or geometry of the springs.
  • EP0626194A1 Another prior art device is EP0626194A1 disclosed.
  • a slide is supported by several leaf springs connected in series in such a way that it can oscillate in three dimensions.
  • the oscillation is excited by controlling coils that exert a force on permanent magnets that are connected to the individual oscillating springs.
  • the spring constants of the springs can be changed in all directions by superimposing the Springs with another spring system happens.
  • the series connection of a spring rod is mentioned here, the spring constant of which can be changed by an adjustable oscillating mass or an adjustable guide fork.
  • the document points out that the oscillating apparatus is usually operated at high frequencies of up to 20 kHz. Areas of application are mixing, homogenization and separation of liquids and solids on a laboratory scale.
  • the mechanical structure of the spring system and the device for adjusting the spring constant by means of an additional oscillating rod are expensive, complicated and take up a lot of space. Applications are limited to mixing smaller quantities of liquids and solids. The masses and amplitudes are small and the frequencies are large, designed for the respective process on a laboratory scale. A true-to-scale design for larger volumes, amplitudes, weights and mixing power would, however, involve enormous effort. Especially the device for adjusting the spring constants would no longer be economically feasible in a scale-up.
  • US2017/333857 discloses an apparatus according to the preamble of claim 1. It shows an actuator for mixing and shaking the contents of a container by linear back and forth motion by means of magnetic excitation.
  • the drive has an electromagnet and one or more magnets to which or which a shaft is attached.
  • the shaft extends into the container and a shaking or mixing plate is attached to the end of the shaft.
  • the electromagnet When the electromagnet is activated, the shaft is moved linearly in the direction of a magnet.
  • a reverse movement of the shaft is effected by reversing the polarity of the voltage on the electromagnet.
  • the linear return movement can be initiated by switching the electromagnet on and off and using gravity or a spring force.
  • Alternating magnetic flux for reciprocation can also be effected by physical movement of a permanent magnet outside the container.
  • DE 11 19 994 discloses a stirring device for the contents of closed vessels, which is moved linearly by an external magnetic field.
  • a The stirring shaft moves up and down with a magnetic anchor element, with compression springs acting linearly in the same direction limiting the movement.
  • a constant magnetic field acting on the armature element is stationary while two interconnected, cylindrical pole shoes arranged in a predetermined relative position to one another are moved up and down together in the direction of stirring, manually or by a drive intended for them, and the magnetic armature element is moved.
  • the object of the present invention is to create a device for mixing liquids and solids in liquids by means of vibration, in which a drive shaft is excited to oscillate in a main direction by means of an electromagnetic drive via a spring system.
  • the device should be designed in such a way that larger forces and amplitudes of several millimeters can be achieved at a frequency of up to 200 Hz.
  • the mechanical structure of the spring system should be optimized in such a way that the known problems are reduced or prevented.
  • a device for mixing liquids and solids in liquids by means of vibration, which has an electromagnetic drive, either a permanent magnet or a magnetisable, for example a ferritic element, and a drive shaft arranged coaxially with the electromagnetic drive.
  • the device has a system of spring elements with several flat spring elements. The spring system allows oscillation in one direction of oscillation, namely the main direction coaxial with the drive shaft and the electromagnetic drive, and is excited to oscillate centrally by an external force. This excitation force is generated by an electromagnetic drive, which transmits a force to a permanent magnet or a magnetizable element by means of a magnetic coupling.
  • the permanent magnet or the magnetizable element is connected to the spring system and enables the oscillation to be excited. Does the device according to the invention a permanent magnet, ie with a constant pole, the permanent magnet will resonate with the input frequency of the electromagnetic coil of the electromagnet. If the device according to the invention has a magnetizable element instead, this element is magnetized by the electromagnetic coil of the electromagnet and will therefore oscillate at twice the input frequency of the electromagnet.
  • the loading condition of the unidirectional oscillation is given by the main forces along the oscillation amplitude along the induced magnetic force, which are transmitted to the drive shaft and thus to a mixing element attached to the drive shaft.
  • first flat spring elements are arranged parallel to the main direction and to the drive shaft, and further, second, flat spring elements are arranged perpendicular to the main direction and to the drive shaft.
  • the latter second spring elements are connected to the permanent magnet or the magnetizable element.
  • the system of flat spring elements comprises a plurality of interconnected flat spring elements which are oriented perpendicularly to one another, or one or more curved flat spring elements.
  • the curved spring elements are each L-shaped designed.
  • the system has two L-shaped curved spring elements, each of the two L-shaped spring elements comprising a first spring element aligned parallel to the drive shaft and a second spring element aligned perpendicular to the drive shaft.
  • a bent, flat spring element is U-shaped.
  • a U-shape is to be understood as meaning a one-piece spring element which comprises two spring elements aligned parallel to the drive shaft and one spring element aligned perpendicular to the drive shaft.
  • the spring elements contain heavy-duty, elastic material, such as spring steel or fiber-reinforced plastic.
  • the first spring elements are fastened and mounted on the wall of a housing by means of clamping jaws.
  • the second spring elements are fastened and mounted on the permanent magnet or magnetizable element by means of clamping jaws.
  • the clamping lengths and widths of the spring elements in the clamping jaws and/or the distance between the spring elements and the electromagnetic drive can be adjusted.
  • the first spring elements are each realized by a damping block which absorbs the transverse forces.
  • Damping blocks also known by the term silent blocks, are to be understood as damping elements with a multi-layer structure, which have two metal plates and a shock-absorbing material arranged between the two metal plates.
  • the shock-absorbing material is rubber or plastic foam, for example, and absorbs the transverse forces in the second spring element perpendicular to the drive shaft.
  • the damping blocks are attached directly to the wall of an enclosure.
  • Flat spring elements can be produced cheaply in different materials and under tight geometry and material tolerances. It is usually made of spring steel or fiber-reinforced plastic. The latter offers increased resistance to alternating stress while maintaining high strength and low weight. In addition, the modulus of elasticity and thus the vibration behavior of the leaf spring can be preselected by a suitable choice of plastic. In the stress conditions described, the flat spring elements show an enormous longevity, even under high alternating loads. They are also compact and lightweight compared to conventional hairsprings. The storage and fixing of the flat springs is simple, easy to assemble and, given the compactness and the defined clamping of the springs, they generate hardly any noise.
  • the separate distribution of the spring elements according to the forces that occur allows flexible and easy adjustment of the clamped spring lengths and the position of the spring system in relation to the excitation force. This enables the system's resonant frequency to be fine-tuned and the electromagnetic drive to be utilized in the best possible way. Asymmetries in the components and groups can be compensated for by the flexible clamping of the spring elements and enable optimal vibration behavior.
  • the design of the spring system of the device according to the invention makes it possible for larger forces and amplitudes of several millimeters to be achieved at a frequency of up to 200 Hz.
  • the device can be used for mixing and homogenizing volumes in the order of 10,000L.
  • the use of a permanent magnet or a magnetizable element as the opposite pole to the electromagnetic drive can provide advantages.
  • the device according to the invention With the use of a permanent magnet, the device according to the invention generates half the oscillation frequency compared to the device with a magnetizable element under otherwise identical conditions. Especially at low operating frequencies, the use of permanent magnets can thus increase the drive efficiency, since the electromagnetic drive can usually be operated more efficiently at higher input frequencies.
  • the mechanical and thermal properties of the magnetizable element, mostly consisting of ferritic material, or the permanent magnet, mostly neodymium-iron-boron compounds are advantageously used depending on the application requirements.
  • the device according to the invention achieves the advantages that the service life and possible operating time of the stressed spring elements are increased because the load on the spring elements is optimally distributed due to the design according to the invention.
  • the device During operation of the device, there is a reduced generation of noise, which otherwise occurs at the high operating frequencies due to spiral springs and their bearings.
