Definitions

  • the present invention relates to a method for accelerating liquid and pourable goods and an apparatus for performing this method.
  • accelerations for the treatment of various goods by centrifugation are well known. Accelerations are generated which are limited by the components of the centrifugal machine (drive, shaft bearing 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 on the one hand due to limited acceleration values and, on the other hand, there is insufficient performance because the centrifugal machine has to be started up and braked.
  • a method for the treatment of 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 container while the impulses are applied to the bottom of the container.
  • Elastic deformations occur in the soil, under the influence of which the particles of the material to be treated are accelerated and are displaced relative to one another (SU, A, 775559).
  • GB-A-2 057 655 describes a generic method and a device, wherein a pulsating current is applied to dry a bed arranged in a container. This current generates an electromagnetic field in a coil, which induces a current in a conductive material which is arranged near the coil. A mechanical movement of the material is caused by the induced current, whereby the container wall arranged on the material is also moved. As a result of this elastic deformation of the container wall, it is subjected to a high load, which limits the maximum pulse frequency and slope and also leads to energy loss.
  • the object of the invention is to provide a method for accelerating liquid and pourable goods, in which the conversion of electromagnetic to mechanical energy of the material to be treated takes place with minimal losses, and to implement a device for carrying out this method.
  • the inventive method for accelerating liquid and pourable goods by converting an electromagnetic pulse energy of an element for generating an electromagnetic field into a mechanical energy given to the material to be treated contains the conversion of the energy of the electromagnetic pulse into mechanical energy with the aid of a plate-shaped element made of electrically conductive Material.
  • This element has at least one degree of freedom in the predetermined direction of acceleration, the opposite surfaces of the plate-shaped element being brought into physical contact with the same or the material to be treated at the moment the electromagnetic pulse is emitted by the element.
  • the super high accelerations in the order of magnitude of a few 1000 g which take place when the method according to the invention is carried out for accelerating the liquid and pourable goods are produced by inducing a secondary field in the plate-shaped element which is associated with the primary electromagnetic field of the pulse emitter interacts, which leads to the formation of a mechanical pulse of high energy.
  • the material to be treated is water, it is expedient to direct its current onto a surface of the plate-shaped element, the electromagnetic pulses being emitted in uninterrupted operation.
  • the material to be treated prefferably be a biological substance which 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 is. This ensures that the pulse is saturated with maximum energy, which produces a high acceleration, which 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 an element for generating an electromagnetic field, a converter for converting the energy of an electromagnetic pulse of the element into mechanical energy being provided according to the invention, which is designed as a plate-shaped element which is arranged with at least one degree of freedom, one surface of the plate-shaped element being in physical contact with the element 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, said plate-shaped elements 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 element for generating an electromagnetic field stands.
  • a device can e.g. B., 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.
  • the device has an element 1 for generating an electromagnetic pulse, hereinafter also referred to as a radiator, which is connected to a source 2 (a generator) for electromagnetic pulses.
  • a source 2 a generator
  • 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 element 1 or the radiator.
  • 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 in the instant 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 pipe, by a conveyor and the like. lead.
  • 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).
  • 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 it can destroy the plate-shaped element 3 as a result of extremely large 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 is used for the sterilization of biological objects, e.g. B. any biological material for medical or food purposes and dressing materials with biological liquids.
  • This device also contains devices 15 for heat or ionizing radiation. A combined action on harmful microorganisms with high accelerations and radiation is guaranteed.
  • FIG. 4 shows a method for drying and compacting, in which a capsule 6 with openings is used.
  • the good M is accommodated 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 the 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 1, 1 ', radiators 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 one another at high speeds, so that their intensive mixing, their heat exchange and their mutual comminution take place.
  • the device shown in FIG. 6 can be used as a variant of the device shown in FIG. 5 and also has a deflector 9 for comminuting particles of a good M.
  • radiators 1, 1 ' In the device shown in FIG. 7 there are also pairs of radiators 1, 1 ', sources 2, 2' and plate-shaped elements 3, 3 ', but they are arranged opposite one another.
  • the plate-shaped element 3 ' has return springs 10 which are installed in supports 11. This embodiment of the device ensures intensive comminution of the good M and mixing it with the good M ', which can also be subjected to comminution.
