Definitions

  • the present invention relates to a method for accelerating liquid and pourable goods and a device for carrying out this method.
  • accelerations to treat various goods by centrifugation are well known. Accelerations are generated which are limited by the components of the centrifugal machine (drive, bearing of the shaft and the like). In addition, a certain start-up time is required to accelerate a product in the centrifugal machine centrifuge bowl. Thus, the treatment intensity is limited because of the limited acceleration size and the result is insufficient performance because the centrifugal machine has to be started up and slowed down.
  • a method for treating liquid and pourable goods in which the goods to be treated are given an acceleration with the aid of electromagnetic pulses.
  • the material to be treated is placed in a vessel while the impulses are applied to the bottom of the vessel.
  • Elastic deformation occurs in the floor. under the influence of which the particles of the material to be treated receive an acceleration and are displaced relative to one another (SU, A, 775559).
  • a disadvantage of this method is that a considerable amount of energy is generated by electromagnetic pulses for the elastic deformation of the vessel bottom get lost.
  • the lighting effects achieved are not very high (2 to 5 g), which means that there is no possibility of intensifying the treatment process.
  • the invention is based on the object of creating such a method for accelerating goods to be treated, in which the conversion of electromagnetic energy into mechanical takes place with minimal unproductive losses, and to develop a device for carrying out this method
  • the object is achieved in that in the method for accelerating liquid and pourable goods by converting an electromagnetic pulse energy of a radiator into a mechanical energy given to the material to be treated, according to the invention the conversion of the energy of the electromagnetic pulse into mechanical energy with the aid of a plate-shaped element is made of electrically conductive material which has at least one degree of freedom in the predetermined acceleration direction, the opposite surfaces of the plate-shaped element being brought into physical contact with the emitter or the material to be treated at the moment the emitter emits the electromagnetic pulse.
  • the material to be treated is water, the current of which is directed onto a surface of the plate-shaped element, the electromagnetic pulses being emitted in uninterrupted operation.
  • the material to be treated is a biological substance that is to be sterilized.
  • the biological substance is placed on only one surface of the plate-shaped element.
  • the streams of different materials, which are subject to mixing, are expediently conducted simultaneously onto the surface of the plate-shaped element.
  • the leading edge of the pulse is determined by the rise time, which is 10 to 20% of the pulse duration. This ensures that the pulse is saturated with maximum energy, which creates a high acceleration is achieved by high intensity of the interaction of the primary and secondary fields in the power transmission element.
  • the method according to the invention is carried out with a device which has a source for electromagnetic pulses which is connected to a radiator, the device according to the invention containing a converter for converting the energy of an electromagnetic pulse of the radiator into mechanical energy, which is in the form of a plate-shaped element is formed, which is installed with at least one degree of freedom, one surface of the plate-shaped element being in physical contact with the radiator and the other surface serving to receive the material to be treated.
  • the device according to the invention contains at least one additional plate-shaped element, the plate-shaped elements mentioned being arranged at an angle to one another, and that each additional plate-shaped element has a surface which is in physical contact with an associated radiator.
  • a device can be used, for example, for mixing different goods, for heat and mass exchange and the like.
  • the device according to the invention with a deflector which is arranged at a distance from the surface of the plate-shaped element and parallel to the surface of the latter, which serves to receive the material to be treated.
  • This device ensures a high degree of effectiveness in the comminution and atomization of a pourable or liquid material.
  • FIG. 1 shows a schematic representation of a device for carrying out the method according to the invention
  • Fig. 7 shows another embodiment of the device.
  • the device has a radiator 1 of an electromagnetic pulse, which is connected to a source 2 (a generator) for electromagnetic pulses.
  • the conversion of the electromagnetic pulse is carried out by means of a plate-shaped element 3, one surface of which is in contact with the radiator 2.
  • a container which is delimited by the wall 4, serves to hold a good M to be treated, which is brought into physical contact with the other surface of the plate-shaped element 3 at the moment of the emission of a pulse.
  • the material M can be placed on the surface of the plate-shaped element 3 in advance and can be placed on its surface at the point in time which precedes the transmission of the pulse, via a pipeline, by a conveyor and the like. conduct.
  • the plate-shaped element 3 is made of an electrically conductive material, preferably copper or aluminum.
  • the plate is mounted with at least one degree of freedom in the predetermined direction of acceleration (possibly vertically upwards), and its displacement is limited by stops 5 (FIG. 1).
  • an electromagnetic secondary field is induced in the plate-shaped element 3 with this pulse, whereby a mechanical pulse is formed by a resulting field that is perpendicular to the plane of the plate-shaped element 3 is directed.
  • Practically all of the energy is converted into displacements of the particles of the material M to be treated, because the freely arranged plate-shaped element 3 is not deformed.
  • the accelerations that can be developed which are determined by the energy of the impulse and the mass of the material to be treated, reach hundreds and even thousands of g, which ensures a high treatment intensity. For example, when drying, dehumidification takes place under the Effect of huge mass forces that are applied to each particle, moreover, disintegration of particles can take place with the separation of particles with different specific weights, which is only possible under the effect of super high accelerations.
  • the leading edge of the pulse is determined by the rise time, which is 10 to 20% of the pulse duration.
  • a rise time that is shorter than 10% of the pulse duration is considered unsuitable because the plate-shaped element 3 can be destroyed as a result of extremely high stresses caused by inertial forces. If the rise time is longer than 20% of the pulse duration, the energy of the pulse is reduced and the accelerations obtained thereby decrease.
  • the material to be treated can be water (or another liquid), the flow of which (FIG. 2) is directed onto a surface of the plate-shaped element 3, the electromagnetic pulses being emitted by the radiator 1 in uninterrupted operation.
  • the wall 4 (FIG. 2) forms a graduation tower, in which the cooling of water takes place more intensively than in conventional graduation towers, which is achieved by high accelerations. This makes it possible to reduce the amount of recooling water.
  • FIG. 3 shows a device in which the method according to the invention for the sterilization of biological objects (as which any biological material for medical or food purposes as well as dressing materials with biological liquids and the like can be considered).
  • This device additionally contains radiators 5 for heat or ionizing radiation. A combined action on harmful microorganisms with high loading accelerations and radiation guaranteed.
  • FIG. 4 illustrates a method for drying and compacting, in which a capsule 6 with openings is used.
  • the good M is placed in the capsule 6, which is placed on the plate-shaped element 3.
  • a super high acceleration leads to a strong compression of the material M in the capsule and to the pressing out of a moisture which is removed via the openings 7. Tableting can be carried out by this method.
  • FIG. 5 shows a device for mixing two different goods, in which the same sources I, I ', emitters 2, 2' of electromagnetic pulses and plate-shaped elements 3, 3 'are present.
  • Goods M, M 'are conveyed via pipes 8, 8', while the plate-shaped elements 3, 3 'are arranged opposite deflectors 9, 9'.
  • the electromagnetic pulses are emitted, the goods M, M 'experience an acceleration in the vertical direction, are thrown back by the deflectors 9, 9', meet each other at high speeds, so that their intensive mixing, their heat exchange and their mutual comminution take place.
