Claims

[Claims for Utility Model Registration] 1. A tank for powdered or granular material, a fluidization barrier in the tank, an outlet for the material flowing from the upper part of the barrier in the tank, and an outlet opening in the lower part of the barrier. an inlet conduit for pressurized fluidizing gas, a transport conduit connected to the outlet, and an inlet conduit for pressurized transport gas opening into the transport conduit;
a first valve in the inlet conduit for fluidizing gas, a second valve in the inlet conduit for transport gas, and both the first and second valves depending on the pressure in the transport conduit; , as follows: When the pressure drops below a certain first predetermined value, by increasing the supply rate of fluidized gas, the pressure increases above a certain second predetermined value. - a control device arranged to control by reducing the supply rate of the fluidizing gas when the supply of fluidizing gas is stopped; and by increasing the supply rate of the transport gas when the supply of the fluidizing gas is stopped; and the controller progressively opens the first valve when the pressure in the transport conduit falls below a predetermined lower limit and the control device is configured to progressively open the first valve when the pressure in the transport conduit falls below a predetermined lower limit. The first valve is progressively occluded when the specified high limit is exceeded, while the first valve is kept open to a substantially constant degree when the pressure in the transport conduit is between the low and high limits. A pneumatic conveyance device for powdered and granular materials arranged to maintain it. 2. The pneumatic transport device according to claim 1, wherein the inlet conduit for the transport gas is connected to the transport conduit adjacent to the outlet. 3. The transport conduit has a bend adjacent to the outlet;
3. A pneumatic transport device according to claim 2, wherein the inlet conduit for the transport gas is connected at the end of the bend remote from the outlet and upstream of the control valve in the transport conduit. 4. According to any of claims 1 to 3 of the utility model registration, in which the pressure averaging conduit connects the tank above the barrier and the inlet conduit for the fluidizing gas above the first valve. The pneumatic transport device described. 5. Pneumatic transport according to any one of claims 1 to 4, wherein the inlet conduit for the fluidizing gas branches off from the inlet conduit for the transport gas upstream of the second valve. Device.
