Definitions

  • the invention relates to a belt press for the dewatering of sludges or the like.
  • Water-containing substances in which sieve belts are guided over dewatering drums and deflection rollers, which are mounted on a frame, and the sludge or the like is pressed between two belt belts, wherein the sludge is fed onto a sieve belt in an approximately horizontal area between two deflection rollers and is conveyed away from the sludge feed point to the gap between the two sieve belts, the frame having two side walls consisting of rigidly connected bars, on which bars the bearings of the dewatering drums and at least a part of the deflecting rollers are fixed, furthermore the drainage drums and deflecting rollers are arranged between the side cheeks and wherein the approximately vertical spars of the side cheeks adjacent to the sludge application point are connection points for bearings for deflecting rollers for that screen belt, on we the sludge is released.
  • the arrangement is selected differently depending on the task of this belt press and on the consistency of the sludge that is considered.
  • the sludge is placed on a sieve belt and with some sludges with a certain consistency the water drips off at the point of application and behind it only by gravity, so that a pre-dewatering takes place here.
  • This zone in which the sludge is already dewatered by gravity, is called the sieving zone and is also provided, for example, in a screen belt press according to AT-PS 340 331, which likewise has deflection rollers protruding from the frame.
  • the object of the invention is to create a uniform frame construction for belt presses with sieving zones that can be set up to different lengths.
  • the invention consists essentially in that to the side cheeks on the sludge feed side projecting beyond the vertical spars, lying in the planes of the side cheeks extension parts can be connected, which have connection points for the bearings at least of the upper deflection roller and optionally for a steering roller holder, which are of the same design like the corresponding connection points on the vertical bars of the side cheeks.
  • extension parts and the equality of the connection points on these extension parts make it possible, using the same side cheeks, to extend the sieving zone and thus adapt it to the properties of the sludge to be dewatered, while treating sludges in which a long sieving zone has no effect , the frame can be used without extension parts and thus the dimensions of the belt press can be reduced.
  • the sludge is fed onto the belt in the zone between the upper pulleys. To achieve a long screen zone, it is sufficient to extend this zone between the upper pulleys.
  • connection points for the bearings of the upper deflection rollers on the vertical bars of the side cheeks and on the extension parts are of the same design, the same bearings can be used and it is only necessary to implement these bearings on the extension parts and to lengthen the feed belt.
  • the length of the second screen belt, which acts only as a press belt, and the arrangement of the drainage drums and deflection rollers on the side cheeks of the frame can remain unchanged regardless of whether the screening zone is extended by the extension parts or not.
  • connection points for the bearings can be arranged on oblique or vertical bars of the extension parts.
  • the connection points on the extension part and the vertical bars of the side cheeks are each in approximately the same position, which further simplifies them.
  • the running of the screen belt can be corrected by castors, which are adjustable in that their bearings are slidably arranged in a holder.
  • the rollers can be slightly inclined relative to the perpendicular to the running direction of the sieve belt, by means of which the running of the sieve belt is corrected.
  • the vertical spars of the side cheeks and the corresponding vertical or oblique spars of the extension parts can also have the same connection points for this swivel castor holder.
  • the arrangement is expediently such that the vertical or oblique spars of the extension parts having connection points are connected at the top to the side walls by approximately horizontal spars.
  • the arrangement can be such that the extension parts are connected to the side cheeks at the bottom by wholly or partially obliquely sloping to the vertical struts of the side cheeks.
  • These oblique spars of the extension parts make it possible for the bearings of the lower deflection roller for the sieve belt to which the sludge is applied to the extension of the filter zone or when connecting the extension parts Connection points on the vertical bars of the side cheeks can remain.
  • the two sides of the extension parts can be connected to one another by means of spars connected to the crossing points of the horizontal spars with the vertical or oblique spars to form a fixed unit.
  • FIG. 1 to 4 show simplified views of the belt press in side views.
  • Fig. 1 shows belt press without Longer side réellesmaschine g. 2, 3 and 4 show different variants of extension parts connected to the side cheeks of the belt filter press according to FIG. 1.
  • 5 shows an end view of the frame of the belt press according to FIG. 1 in the direction of arrow V of FIG. 1.
  • the sludge is fed in at the point indicated by an arrow 2 onto the sieve belt 3r which runs in the direction of the arrow 4.
  • 8 is an adjustable swivel castor which serves to correct the sieve belt run and whose holder 9 is connected to the vertical bars 5 of the side cheeks 1.
  • the sludge passes from the sieve belt 3 to the second sieve belt 10 and is conveyed between the sieve belts 3 and 10 via dewatering drums and deflection rollers.
  • FIG. 5 A front view of this frame 13 in the direction of arrow V according to FIG. 1 is shown in FIG. 5, which only shows the frame 13 with the omission of the drainage drums, the deflection rollers and the steering rollers.
  • an extension part 16 is connected to the feed side of the side cheeks 1.
  • Each of these extension parts 16 has a vertical spar 17 and two horizontal spars 18 and 19.
  • the vertical spar 17 has connection points for the bearings of the upper guide roller 6 and the lower guide roller 7, which are now in the position 6 'or 7'.
  • These connection points are of the same design as the connection points on the vertical spar and the bearings of the upper and lower deflection rollers 6 and 7 can therefore be easily connected to the vertical spars 17 of the extension parts 16.
  • the sludge feed can now take place at the point indicated by the arrow 20, so that a long filter zone 21 is formed behind this sludge feed point.
  • the swivel castor which is used to correct the belt run, now also comes into position '8' and the holder 9 of this swivel castor comes into position 9 '.
  • the sieve belt 3 reaches the position 3 '.
  • the embodiment according to FIG. 3 differs from the embodiment according to FIG. 2 in that the extension parts 22 attached to the side cheeks 1 have spars 23, some of which extend obliquely to the vertical spar 5.
  • the upper deflection roller 6 now reaches the position 6 "on a vertical part 24 of the spar and the steering roller 8 reaches the position 8", the holder 9 of this steering roller reaching the position 9 ".
  • the lower deflection roller 7 can remain in its position on the vertical spars 5 due to the inclined part of the spar 23.
  • the filter zone 21 is again extended and the Sludge is now applied at the point indicated by arrow 20.
  • the horizontal bars 18 of the extension parts 25 are connected to the side walls 1 by oblique bars 26.
  • the bearings of the upper guide roller 6 and the bracket 9 of the steering roller 8 are now connected to the connection points of the oblique spars 26.
  • the upper deflection roller 6 therefore comes into position 6 '' '
  • the steering roller 8 comes into position 8' ''
  • the holder of this steering roller comes into position 9 '' '.
  • the sieve belt 3 now runs in the position 3 '' '.
  • the sludge feed occurs again at the location of the arrow 20 and so a long filter zone 21 is created again.
  • the bearings of the lower deflection roller 7 can remain at the connection points of the vertical spars 5, so that the lower deflection roller is in its position 7 remains.
