Definitions

  • the invention relates to a device for mechanical dewatering of product or sewage sludge on site.
  • This device consists of a commercially available plate filter press and a frame holding this press, which is provided with correspondingly adjustable lifting supports.
  • Plate filter presses that can be set up to dewater sludge at the sludge collection site are known (brochure ACHEMA 1985 from F. Schlammpress-Technik und Industriergraphy GmbH & Co KG / Dormagen).
  • a plate filter press is mounted on a standard semi-trailer.
  • the trailer has extendable jacks at the four corners, which hold the filter press at such a height that the filter cake can be collected and transported away, for example, in transport rubbish containers.
  • the task was to develop a transport device for a plate filter press that has a significantly higher capacity. To do this, it is necessary to use the transport width and height of a heavy transporter as much as possible and to modify the frame so that it can be set up and dismantled under its own power.
  • the frame is designed for transport by a low loader and is provided with hydraulic multi-stage adjustable jacks which are pivoted into the outline of the frame in their highest position.
  • the frame is therefore not itself a transport element, but has the dimensions and strength for transport by a standard low loader. Since a low loader allows a significantly higher overall height of the filter press than a semi-trailer, a larger capacity press can be used.
  • the pivoting device for each lifting support preferably consists of a vertically upwardly projecting bearing pin anchored to a frame corner and a bearing bush which can be pivoted about this bearing pin and which carries the sliding guide for the lifting support to a very short extension arm.
  • the lift support and sliding guide preferably have a rectangular or square cross section, so that there is no need for rotation locks.
  • the bearing bush can preferably be locked in the two positions of the cantilever arm by a cross pin.
  • the frame 1 consists of two crossheads 2 and two longitudinal profiles 3, which are connected at the corners by nodes 4.
  • the plate filter press 5 sits with its stands 6 only on the crossheads 2 and is secured there by pin 7 against displacement.
  • the triangular holders 8 provided on the longitudinal profiles 3 serve to prevent the tie rods 9 of the filter press 5 from sagging in the unloaded state.
  • the design of the lifting support pivot bearing 10 can be seen.
  • a tightly fitted bearing bush 13 which carries a short extension arm 14 with a double-T profile.
  • the slide guide 15 is attached for the lifting support 16 consisting of a square tube. Both bearing elements can be locked by transverse pins 17, 18 in the pivoted-out position of the slide guide 15.
  • the Bearing bush 13 has on its rear side a pull tab 19 which can be screwed to the top of the press stand 6 when the lifting support 16 is pivoted out. In this way, the leg bearing is connected to the filter press in the raised state of the frame to form a structure that is resistant to pressure and tension. The support forces are transferred to the press without generating bending and shear moments.
  • the device for stroke adjustment of the lifting support contains a double-acting hydraulic piston 20, a coupling fork 21 and a lockable with the lifting support 16 (cross pin 22) slide shoe 23, in the side fork 24 of which the head of the piston rod 25 is articulated.
  • the slide shoe 23 is closed at the bottom and has a socket 26 there for the stand base 27 provided with a corresponding plug pin, which has a wide base plate for sitting on a foundation 28 created on site.
  • the socket 26 is dimensioned so that it fits over the spigot 37 seated on the longitudinal profile 3 of the frame and thus securely locks the lifting supports in the pivoted-in state in which they cannot be pinned to the bearing pin 11.
  • Fig. 1 shows the frame with the filter press 5 as it is lifted from the low loader.
  • the press only takes up the space 30 indicated by dash-dotted lines during transport.
  • the lifting supports 16 do not protrude beyond this contour.
  • the jacks are first hydraulically lifted out of the plug pins 7 and then pivoted outwards. In this position, the bearing bushes 13 are locked by the cross pins 17.
  • all four lifting supports 16 are extended synchronously and the stand feet 27 are placed shortly before reaching the foundations. Now they are Now the guide shoes 23 of the piston rod heads are released from the lifting supports 16 by pulling the cross pins 23 and then moved upwards by retracting the piston rods 25. There they are pinned with the lifting supports 16 in the transverse holes 31.
  • the cross pins 18 of the slide guides 15 can be loosened by actuating the hydraulic cylinders in the stroke direction and the lift supports 16 can be extended to the uppermost position in which they are pinned again with the slide guide (cross hole 32).
  • the low loader can be pulled out and the press connected and put into operation.
  • the dismantling takes place in reverse order.
