Definitions

  • the invention relates to a two-cylinder thick matter pump with a swivel-mounted in a loading container, which alternately connects the delivery cylinders to a delivery line, and a flange attached to a wall of the loading container and having at least one screw conveyor, which is connected to a filling funnel.
  • a thick matter pump of this type is known (US Pat. No. 3,465,685), in which the pre-pressing device opening into the loading container with the hopper or with its screw conveyor protrudes far beyond the loading container on one side.
  • the predefined orientation of the pre-pressing device to one side can have a disadvantageous effect when installing or installing the thick matter pump in rooms with small dimensions.
  • the invention has for its object to provide a slurry pump of the type mentioned, which can be adapted better than before despite the protruding pre-pressing device when setting up or installing it.
  • the pre-pressing device is attached to a part of the loading container which can be flange-mounted in different orientations on the other part of the loading container receiving the diverter.
  • the part of the loading container carrying the pre-pressing device can be connected via a horizontal flange to the other part receiving the pipe switch, the part carrying the pre-pressing device expediently forming the lower part of the loading container. If the flange connecting the two parts to one another is square, the pre-pressing device can be brought into different orientations to the conveying cylinders by rotation through 90 ° in each case. Any intermediate layer is also possible when using a round flange.
  • the loading container has a removable or swiveling cover plate. If, in addition, the part of the loading container which receives the pipe switch has an upper and a lower horizontal flange, each with the same dimensions, the part carrying the pre-pressing device and the cover plate can optionally be exchanged for one another.
  • a cover plate located at the bottom would have the advantage that the loading container is more easily accessible for cleaning purposes and the replacement of wear parts becomes easier.
  • the thick matter pump shown in the drawing has a loading container 1, the upper part 11 of which is connected to the lower part 12 by means of a flange 13 and can be closed with a cover plate 14 which can be flanged onto the flange 15.
  • Two feed cylinders 4 and 4 ' open into the rear wall of the upper part 11 of the feed container 1, the pistons 41 of which can be driven in a push-pull manner by hydraulic cylinders 42.
  • the conveying cylinders can be connected alternately to the conveying line S via the swiveling pipe switch 5 having an S-shaped pipe.
  • the pre-pressing device 3 has two intermeshing screw conveyors 31 and 31, which are arranged in a feed channel, which in turn is fed with material to be conveyed via a hopper 2.
  • the pre-pressing device 3 opens into the lower part 12 of the loading container 1.
  • the flange connection 13 between the two parts 11 and 12 of the loading container is square, so that the pre-pressing device by rotating through 90 ° in each Positions shown in dash-dotted lines can be brought.
  • the pre-pressing device can be attached in any direction.
