Definitions

  • This invention provides a vibrator or shaker comprising a pedestal, Support means resiliently suspended in said pedestal, fixing means for rigidly locating a material that [54] VIBRIATOIR 3 i g is to be vibrated on said support means, and means for apply- 4 Ch 3 raw 3 ing a deflecting force to said support means which cyclically [52] US. Cl 259/72 varies at a frequency controllable to generate resonant vibra- [51] lnt.Cl. 1301f 1l/00 tions of the vibratory system constituted by said resiliently [50] Field of Search 259/72, 73, suspended support means andsaid vibrated material located thereon.
  • Such vibrators are needed for thoroughly mixing solutions, suspensions, loose flowable bulk materials and so forth.
  • Conventional vibrators perform a horizontal reciprocatory movement generated by eccentrics, push rods or cable and chain drives.
  • Hydraulically and pneumatically operated vibrators are likewise known in the art. Usually these comprise rigid transmission means for applying a vibratory drive to the support means that are to be shaken. In such vibrators the entire mass of the vibrated material and of the vessel containing the same must first be accelerated in one direction, decelerated and stopped and then reaccelerated again in the opposite direction and so forth. Drive means developing considerable power are needed to overcome the resultant inertial forces.
  • Another major drawback of such vibrators is that the transmission of the drive by rigid mechanical elements limits the amplitude of vibratory motion.
  • Another object of the invention is to eliminate the need for rigid transmission members and thereby to reduce wear and noise to a minimum.
  • Yet another object of the invention is so to contrive the vibrator that it can be used not only for shaking but also forstirring liquids of flowable solid materials.
  • the vibrator proposed by the present invention substantially comprises a pedestal, support means resiliently suspended in said pedestaL'fixing means for rigidly locating a material that is to be vibrated on said support means, and means for applying a deflecting force to said support means which cyclically variesat a frequency controllable to generate resonant vibrations of the vibratory ⁇ system constituted by said resiliently suspended support means and said vibrated material located thereon.
  • the resilient suspension of the support means permits the latter to be excited to vibrate at its natural frequencyi' provided the frequency of the exciting force is kept inste'pgwith this natural frequency. Under resonant conditions a very high vibratory output can be achieved with a very small input.
  • a vibrator may'comprise magnet means for applying a cyclically changing exciting force to said support means.
  • the use of magnetic-forces-for this purpose has the advantage that it eliminates the need for mechanical transmission members between the drive and the vibrating system.
  • the vibratory system maybe resiliently suspended to vibrate substantially in the vertical.
  • the vibratory system in thecontextof the specification is understood to comprise saidsupport means and its suspension as well as the material that is to be vibrated and the means for locating the material on said support means.
  • a suspension which is adapted to permit vertical vibratory motion of the support means has the advantage of being particularly easy to provide and of permitting material such as a liquid to be fixed and located on the support means in the mostconvenient way.
  • the resiliently suspended support means may contain a ferromagnetic material responsive to the field of an exciting magnet in proximity with said support means, and control means may be provided for controlling the magnetic field, the purpose of the control means being to vary the magnetic field in such a way that deflecting forces can be cyclically applied to the support means at a desired rate.
  • a particularly useful and simple embodiment of the proposed vibrator comprises a first magnet directly and rigidly affixed to said resiliently suspended support means, an exciting magnet 'rotatably mounted in close proximity with and parallel to said first magnet and drive means for rotating said rotatable magnet.
  • the term parallel in this context is understood to mean that the two magnets are so mountedthat rotation of the exciting magnet alternately brings poles of like and opposed polarity of said two magnets into cooperating juxtaposition.
  • rotation of the exciting magnet causes a cyclic variation of the magnetic field which reverses its direction at the frequency of rotation of the rotating magnet.
  • the exciting magnet may be driven by a controllably variable speed motor which will permit the periodicity of the driving force to be conveniently adjusted to bring it into step with the natural frequency of the vibratory system, like and'unlike poles cooperating alternately to apply forces of attraction and repulsion to the mountingmeans. Owing to the resilient suspension of the mounting means the latter can thus be excited to swing up and down at the natural frequency of the vibrating system.
  • a preferred embodiment of the invention may com-- prise a supportmeans in the form of a resiliently suspended horizontal mounting plate, a first magnet in the form of a bar magnet rigidly affixed to the underside of said mounting plate and an exciting magnet in the form of a bar magnet of the same shape and configuration as said first magnet so mounted that rotation of said exciting magnet alternately brings poles of like and opposed polarity of said two magnets into cooperating juxtaposition.
  • the mounting plate and fixing means couldbe replaced by a resiliently suspended container for the vibrated material, and the first magnet could be directly affixed to said container. In such forms of construction the downward pull exerted on the vibrating system when unlike poles-of thetwo magnets attract each other will.
  • an intensified rotating magnetic field This can be conveniently used for stirring a liquid or like material in acontainer on the mounting plate by inserting a freely rotatable magnet into the container roughly parallel to the two magnets under the mounting plate.
  • the magnet inside the container will likewise participate in the rotation of the two latter magnets and thus stir the contents of the container without the necessity of providing amechanical drive means.
  • the provision of an optionally releasable first magnet on the underside of the mounting plate thus permits the vibrator to be optionally also used as a stirrer.
  • the excitingmagnet may with advantage be an electromagnet and the first magnet on the underside of the mounting plate may likewise be an electromagnet.
  • a modified form of construction of the proposed vibrator may comprise a stationary electromagnet to serve as the exciting magnet and electrical or electronic means associated with a controller for cyclically reversing the polarity of the exciting magnet which cooperates with a magnet affixed to the mounting plate.
  • the mounting means may consist of a ferromagnetic material in which case a cyclic increase and decrease of the intensity of the magnetic field will already be sufficient to attract and release the mounting means and to cause it to build up vibrations in its resilient suspension.
  • the mounting means may have the form of a mounting plate made of soft iron which responds to the field of the electromagnet. The latter will then periodically attract and release the resiliently suspended soft iron plate to which the material that is to be vibrated is firmly attached. The vibratory motion which can thus be built up is thus transmitted to the material.
  • the amplitude as well as the frequency of the intensity variations of the magnetic field may both be adjustable by control means-associated with the electromagnet.
  • the preferably electronic control means may be adapted to generateand maintain the frequency of the magnetic field variations in step with the natural frequency of the vibrated system.
  • the mounting plate may be an advantage to provide the mounting plate with heating means, since it is often desirable to heat a vibrated material such as a liquid or to maintain it at a given temperature whilst it is being vibrated for the purpose of reducing its viscosity to a level at which vibration will be fully effective.
  • the heating means may be built into the mounting plate or attachable thereto.
  • an elastic transmission is still capable of transmitting cyclically varying forces in such a way that the frequency of the latter can be brought into step with the natural frequency of the vibratory system to achieve maximum vibratory output with a minimum input energy.
  • at least one spring extending in the direction of deflection maybe attached to the mounting plate and a cyclically varying force applied to the free end of said spring, the frequency of said latter force being varied until it is in tune with the natural frequency of the system.
