The invention relates to a device for the mechanical lifting and conveying away of coal sludge from a sludge basin with a lifting shovel and a system of conveyors. Such known devices are in the form of an adjustable shovel which is used to convey away the sludge is coupled either to interchangeable trolleys or to a conveyor system. In the first case is the shovel for generating the feed movement with the carriage of a sliding cable car by means of coupled with a rope, while in the second case with an electric car, which is on an over the mud basin of the tensioned bridge construction moves, is coupled. In the latter case is the Scraper conveyor removing the sludge from the bucket in the direction of the work feed attached in a parallel plane.

In addition to being relatively complex in construction, these known devices have had the disadvantage on that they use special supporting structures, such. B. in the form of bridge fields required. In addition, the parallel arrangement of the lift-off blade made difficult with limited adjustability of the Scraper conveyor lifts the sludge to different depths.

From the German Auslegeschrift 1093 780 is a device for discharging sludge from the ground a sedimentation vessel known in which the sedimentation vessel is round and radially extending screws over the sloping inwardly inclined bottom when they are carried by a suitable support device over the bottom of the vessel be moved away. Such a construction is structurally very complex, since the screw must extend over the entire radius of the sedimentation vessel. Furthermore, the worm works immediately at the bottom of the vessel. It can therefore not be used for upward promotion. this leads to in turn to the fact that a use for lifting coal sludge from sludge basins is not at all is possible. Rather, the prerequisite for the use of the construction according to this interpretative document is that the screw at the bottom of a basin filled with water works and there the solids to the deepest Moved point of the basin, where it is drawn off by means of liquid pumping.

Finally, from US Pat. No. 2 298 332, a screw conveyor device is known which to be used for unloading grain silos. For this purpose a screw is provided which is pivotally mounted and is in the silo for the purpose of conveying out the material lying at the bottom of the silo

cereal can be inserted. Such a screw construction is used for conveying from bottom to top Unsuitable because most of their length does not have baffles only convey the provided screw at the bottom of a channel dug by the screw itself in the conveyed material can. There is also no device provided to move the screw transversely to the direction of its axis to promote an area to be withdrawn. Finally, there is also no shovel for lifting the conveyed goods. The well-known auger is only suitable for sliding bulk material from above, which is ready by default, further down to promote.

The last two facilities described are only suitable for conveying from top to bottom, because they have screw conveyors that work without a housing.

The invention is based on the object of creating a device of the type outlined above, which is simple and reliable in construction and allows the Raise coal sludge at different distances from the horizontal plane of the conveyor and promote to the edge of the pool.

Experience has shown that this is achieved by the fact that an over the basin extending on his entire length of loadable, transversely to its conveying direction displaceable horizontal conveyor provided is on which a lifting device supporting
