    专利说明:

    conical end 16 extends down through the cap 17 of the cylindrical part and acts as an air outlet to the atmosphere. The axial position of the vortex collector can be adjusted as indicated by the jacks 18,19. A choke for the outlet is formed by a cone 20 so that an annular outlet gap 21 is formed and this gap can be adjusted by adjusting the axial position of the cone 20 relative to the pipe 15 with the screw 22.
    When air or other gas is blown in by a shaft (not shown) in the supply line 12, a downward vortex is formed which then turns and forms a central ascending vortex which is captured by the vortex collector 15. The dashed lines 30 show the boundary between overpressure on the outside and underpressure on the inside of it.
    The bottom outlet 14 is shown enlarged as Figure 2 and shows that material M supplied to the supply air in the supply line 12 deposits on the conical wall and travels downwards along the wall and out of the outlet. As can be seen in the fi gure of the dashed lines 30 also found in fi gur 1, there is overpressure along the wall but negative pressure in the center of the outlet so that air flows in as indicated by the arrow 32, so material can alternatively be introduced there instead of in the air supply line 12.
    The outlet 14 can be modified to be annular. The cyclone and its properties are not described in more detail because a cyclone of this type is described in more detail in US 5,236,132, US 5,598,979 and US 6,517,015 B2. Reference is made to these writings.
    A material or mixture of materials M is fed to a cyclone device 10 at a material feed point 40 in the supply line 12 (see Figure 3), the cyclone device decomposing the material mixture into smaller fractions and drying the material mixture. The ground and dried material mixture M leaves the cyclone device 10 at the outlet 14.
    A, preferably controllable, fl genuine 50 blows air or other gas G into the supply line 12 as shown in Figure 3. After service in the cyclone device 10, the gas G leaves the cyclone device through an outlet line 52 in which an adjustable throttle valve 54 is provided for tuning the working properties of the cyclone device. The gas G leaving the cyclone device through the outlet line 52 has been given a higher moisture content in connection with the grinding and drying of the material mixture M in the cyclone device 10. The normal procedure is for the gas G to be released into the atmosphere, possibly via a purification device 60 which removes material residues from the gas G.
    Initially, the gas G has been supplied to the device 10 via a supply line 12 in which a heat exchanger 65 is arranged, in which case, for example, waste heat from some industrial process can be used.
    According to the invention, a recirculation line 70 is arranged between the inlet line 12 and the outlet line 52. Valves V1 and V2 for regulating and directing the gas flow G are arranged as indicated in Figure 3.
    According to the invention, the valves V1 and V2 can be set so that the desired proportion of the gas G leaving the cyclone device 10 is recycled to the inlet line 12 to again pass the cyclone device 10. The recirculation can continue until the gas G has reached a desired temperature and moisture uptake capacity. the valve V1 is evacuated to the desired extent to, for example, the atmosphere A via, for example, a purification device 61.
    The aforementioned recirculation can thus be partial by adjusting the valves V1 and V2 so that only a subset of the gas G is recirculated, whereby a limited amount of gas G is evacuated at the gas outlet 75 and a limited amount of gas G is filled at the gas inlet 80.
    The inventive recirculation enables a very large energy saving and the heat exchanger 65 enables a heat supplement which further increases the energy saving.
    By means of a number of sensors and indicators and suitable valve control equipment, an optimized control process for the recirculation can be easily achieved.
    It should be understood that in a simpler embodiment, certain components such as, for example, heat exchangers and purification devices can be omitted. In order to further heat the gas G, a further heat exchanger 90 can be arranged at the outlet of the cyclone device where a gas entrainment takes place. Here, too, waste protection can be used. Even an extra preheating of inlet gas is sometimes beneficial.
    It is also suitable to provide equipment for regulating the system pressure of the circulating gas.
    The invention can, of course, be varied by exchanging function-equivalent components.
    The invention is thus not limited to what is shown and described, but modifications and variations are of course possible within the scope of the appended claims.
