Definitions
- the invention relates to a shock wave generating fragmenting device with a suction device. Particles with at most The target grain size will be selectively from a suspension separated.
- a method and a device is known known, mineral particles in a liquid in suspension to keep.
- the latter ends in a centrifuge separator, in which a first rough separation takes place, wherein the coarse fractions are returned to the shredder and the fines a subsequent, second centrifugal separator be supplied.
- the coarse shares from there are also fed back to the crusher, the fines one Container for collecting the same, the final product. It will the colloid fed to an evaporator and from there finally Dried into a silo.
- the shredding will carried out with purely grind-like process
- the filled in the reaction vessel, in the process fluid sinking Fragmentiergut is in the reaction space between the tip of the high voltage electrode and the bottom of the vessel the electrical discharges of a capacitive energy memory exposed and smashed. From a certain grain size are fractional parts by the discharge or the Shock wave in a row in the process fluid whirled up and distributed in it. It creates a kind of suspension. Not aspirated Fractions on the other hand, decline again and become again exposed to the discharge and thus the further fragmentation.
- the basket at the end of the suction device, which is in the process fluid protrudes, and the mesh surrounding the basket are made of a tough, shockwave resistant material.
- the Mesh size of the fabric determines up to which grain size be sucked in the process liquid floating particles. Particles with overlying grain size, oversize, become held in the process fluid and through the basket incoming shockwave and its dissolving effect again in forced back the fragmentation volume to the subsequent smashing operation to be suspended again.
- the mesh fabric on the one hand from an electrically conductive Fabric such as stainless steel (claim 2), which, as required on the mechanical stress is also chemically resistant to the Process liquid and the substances dissolved therein, or from a Dielectric fabrics such as high-strength plastics with even such mechanically and chemically resistant properties.
- an electrically conductive Fabric such as stainless steel (claim 2), which, as required on the mechanical stress is also chemically resistant to the Process liquid and the substances dissolved therein, or from a Dielectric fabrics such as high-strength plastics with even such mechanically and chemically resistant properties.
- a Fragmentierstrom is outlined, whose Smashing device according to the principle of electrical Discharge of a capacitive energy storage, the FRANKA principle for example, works.
- the drawing shows in her figure 1 the electrodynamic fragmentation in principle and in Figure 2 shows the reaction vessel during the process.
- the reaction vessel ( Figure 2) is partially with process fluid filled, which here is water, because e.g. such substances as Ceramics, glass and minerals should be fragmented.
- process fluid here is water, because e.g. such substances as Ceramics, glass and minerals should be fragmented.
- the high voltage electrode is with an insulation sheathed so that only from the area of their tip the discharges take place towards the bottom of the reaction vessel.
- the soil is here curved, approximately spherical, so that the Process material accumulates there and exposed to discharge safely is.
- the suction device at its beginning is caused by the unloading Shock wave in the process liquid shaken and from the on freed its network fragments, which then in the discharge volume sink back to the next discharge again to be exposed to fragmentation.
- the Absaugkorb sits at the end of the suction device (claim 2), in which the aspirated from the process liquid suspension is transported to the inlet into the sediment tray. The Particles settle there on the ground, and those of suspended matter liberated process liquid is finally returned to the reaction vessel fed.
