Abstract
A turnover device (1) to turn over and mix back moist material (2), in particular sewage sludge, in a drying installation (3) is equipped with at least one shovel (7). The moist material (2) is spread out for drying on floor (4) in the drying installation (3). The shovel (7) is rotatable within a circumference around an axle (8). Directly outside the circumference and essentially above the layer of material a retention device (9) is installed for the moist material (2) and interacts with the shovel (7).
Claims22
Turnover device (1) to turn over and mix back moist material (2), in particular sewage sludge in moist and dried state in a drying installation (3) in which the moist material (2) is spread out on a floor (4) in a layer to be dried, whereby the turnover device (1) is equipped with at least one shovel (7) rotatable within a circumference around an axle (8), characterized in that a retention device (9) for the moist material (2) is installed directly outside the circumference and essentially above the layer of material and interacts with the shovel (7).
Turnover device as in the previous claim, characterized in that the turnover device (1) is provided with a drive to move the turnover device (1) along the bottom (4) and at a right angle to the axle (8) of the turnover device (1).
Turnover device as in one of the previous claims, characterized in that the turnover device (1) is provided with a drive to change the distance between the circumference and the floor (4).
Turnover device as in one of the previous claims, characterized in that the height of the retention device (9) relative to the floor (4) and/or the layer of material can be changed by means of an adjusting device (12).
Turnover device as in one of the previous claims, characterized in that the retention device (9) is a screen (15).
Turnover device as in one of the previous claims, characterized in that the retention device (9) is a tab (16).

Turnover device as in one of the previous claims, characterized in that a raking device (18) is assigned to the turnover device (1).
Turnover device as in one of the previous claims, characterized in that the raking device (18) and the retention device (9) are made as one component.
Turnover device as in one of the previous claims, characterized in that the raking device (18) and/or the retention device (9) is installed before and/or after the turnover device (1) considering the direction of travel of the turnover device (1).
Turnover device as in one of the previous claims, characterized in that a sensor to determine the layer's height is assigned to the turnover device (1).
Turnover device as in one of the previous claims, characterized in that a sensor is connected to controls for the determination of an average layer height.
Turnover device as in one of the previous claims, characterized in that the shovel (7) is installed on a shaft.
Turnover device as in one of the previous claims, characterized in that at least one shovel (7) is installed in a segment and several segments are installed in axial direction on the shaft.
Turnover device as in one of the previous claims, characterized in that the cross-section of the shovel (7) is a polygonal segment similar to a semicircle.
Turnover device as in one of the previous claims, characterized in that the shovel (7) is mounted on a stanchion that is radial relative to the circumference.
Turnover device as in one of the previous claims, characterized in that the shovel (7) extends parallel to the axle (8).
Turnover device as in one of the previous claims, characterized in that several shovels (7) are offset relative to each other in axial direction.
Turnover device as in one of the previous claims, characterized in that the shovel (7) can be stopped in a predetermined position.
Turnover device as in one of the previous claims, characterized in that the turnover device (1) is provided with a support wheel (23).
Turnover device as in one of the previous claims, characterized in that a plow is assigned to the support wheel
