| 摘要 |
The invention relates to a device (1) for removing fluids and/or solid substances from particle-shaped materials, comprising a container (2) forming an annular-shaped process chamber (20) having a cylindrical external contour, devices for introducing and removing the particulate material into and out from the process chamber (20) and a ventilation device (5) for supplying a fluidising agent from below into the process chamber (20), in addition to devices (6) for preparing the fluidizing agent in the direction of flow upstream from the ventilation device. Compartments (15, 16, 17) that extend in the vertical direction are formed in the process chamber (20), from where one forms a discharge compartment (17) that is not cross-flown from below by the fluidising agent, and the discharge device is arranged on the lower end thereof, and on another compartment (15) that is provided with the discharge device. The compartments (15, 16, 17) are open on their upper ends in order to allow the material to be transported to the discharge compartment (17). Rotational blades that are inclined or curved in the direction of flow from the introduction compartment (15) to the discharge compartment (17) are arranged above the process chamber (20), the external diameter of which is not greater than the external diameter of the process chamber (20) and which is surrounded by an outer enveloping (3) that does not protrude radially over the outer enveloping (3) of the process chamber (20). |
