Definitions

  • the invention relates generically to a device for the task of conveyed material to an eccentric screw pump, d. H. a pump of the type of a Moineau pump, with an elongated feed hopper which is rectangular in plan and a closed feed housing, feed screw in the feed housing and bridge breaker arrangement in the feed hopper, the feed screw being built up from a worm shaft and at least one worm web of a predetermined pitch arranged thereon, and the bridge breaker has two bridge breaker shafts parallel to the worm shaft, driven in opposite directions, with attached bridge breaker paddles, the circulation circles of which overlap one another and are brought up close to the circulation circuit of the worm land.
  • sludge in particular activated sludge
  • this sludge has a predrying, z. B. on a so-called belt dryer or vacuum belt dryer.
  • the feed screw and the bridge breaker arrangement generally have independent drives. It works with speeds between 30 to 150 revolutions per minute, mostly selectable.
  • the eccentric screw pump is usually flanged to the screw shaft with its eccentric.
  • the invention has for its object to improve the filling level of the feed screw and thus the overall efficiency of the device in a generic pump.
  • the invention teaches that the bridge breaker paddles are so inclined in relation to the axis of their bridge breaker shaft in accordance with the slope of the screw bridge that the material thrown from the bridge breaker paddles reaches the area of the feed screw essentially tangentially to the direction of the screw bridge.
  • the bridge breaker paddles are less inclined in the area of the bridge breaker shaft than in the area of their ends. As a result, you are wounded.
  • the device according to the invention works with a high degree of filling and high efficiency.
  • fine-grained dry additives e.g. B. Lime and cement, mix very homogeneously.
  • the device explained in the figures is used for feeding material to an eccentric screw pump of the Moineau pump type.
  • the device has an elongated feed hopper 1 with a rectangular layout and a connected feed housing 2.
  • a feed screw 3, 4 rotates in the feed housing 2.
  • a bridge breaker arrangement is provided in the feed hopper 1.
  • the feed screw consists of a screw shaft 3 and a screw web 4 of predetermined pitch arranged thereon.
  • the bridge breaker has two bridge breaker shafts 5, 6, which are parallel to the worm shaft 3 and are driven in opposite directions, with bridge breaker paddles 7, 8 attached.
  • FIGS. 1 and 2 the circulation circles 9 and, indicated by an arrow, the rotation directions can be seen.
  • the circulation circles 9 overlap.
  • the material to be conveyed is dropped between the two bridge breaker shafts 5, 6.
  • the circulation circles 9 are brought up to the envelope of the screw web 4.
  • the distance should be kept as small as possible and be only a few millimeters, for example only 2 to 3 mm. 3
  • the drive motors (not shown) for the feed screw 3, 4 and for the bridge breaker arrangement with their gears and devices are connected upwards.
  • the eccentric screw pump is connected down, the housing 10 has been indicated.
  • the bridge breaker paddles 7, 8 are inclined in relation to the axis 11 of their bridge breaker shaft 5 in accordance with the slope of the screw webs 4 so that the conveyed material dropped by the bridge breaker paddles 7, 8 get into the area of the feed screw 3, 4 essentially tangentially to the direction of the screw flights 4.
  • This throwing direction has been indicated in FIGS. 3 and 4 by arrows 12.
  • the known embodiment is shown on the left in FIG. 4, and the one according to the invention on the right. In this way, a considerable improvement in the filling level of the feed screw 3, 4 and thus an improvement in the efficiency of the device as a whole, including the efficiency of the connected eccentric screw pump, are achieved.
  • the bridge breaker paddles 7, 8 can have a smaller inclined position in the area of the bridge breaker shaft 5, 6 than in the area of their ends. They are twisted in themselves, which was not shown in the drawing.
