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, 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 drainage drums and at least a part of the deflection rollers are defined, furthermore the drainage drums and deflection 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 of deflection rollers for that screen belt, on w what the sludge is abandoned.
  • 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 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 belt press according to AT-C-340331, which also 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 protruding beyond the vertical spars, lying in the planes of the side cheeks, which have connection points for the bearings of at least the upper deflection roller and possibly for a swivel castor bracket, 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 to extend the sieving zone using the same side cheeks and thus to adapt the properties of the sludge to be dewatered, while in the treatment of 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 transfer these bearings to the extension parts and to lengthen the feed belt.
  • the length of the second sieve belt, which only acts 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 straining zone is extended by the extension parts or not.
  • connection points for the bearings can be arranged on inclined or vertical bars of the extension parts.
  • the connection points on the extension part and the vertical spars 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 swivel 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, which have connection points, are connected to the side cheeks by approximately horizontal spars.
  • This takes into account the condition that the zone of the sieve belt in which sludge is applied to it or the sieving zone should be approximately horizontal, the sieving zone being lengthened or shortened only by the position of the upper deflection roller.
  • the arrangement can be such that the extension parts are connected to the side cheeks at the bottom by spars that drop entirely or partially at an angle to the vertical spars of the side cheeks.
  • These oblique spars of the extension parts make it possible for the bearings of the lower deflection roller for the screen belt on which the sludge is to be extended when the filter zone is extended or when the extension parts are connected is applied, can remain at the connection points on the vertical bars of the side cheeks.
  • 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 the belt press without extension parts.
  • 2, 3 and 4 show different variants of extension parts connected to the side cheeks of the belt filter press according to FIG. 1.
  • FIG. 5 shows an end view of the frame of the screen 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 3 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 reaches 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. 5 is shown in FIG. 5, which only shows the frame 13 with the drainage drums, the deflection rollers and the steering rollers omitted.
  • 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 deflection roller 6 and the lower deflection 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 created behind this sludge feed point.
  • the swivel castor which is used to correct the tape run, now also comes into position 8 'and the holder 9 of this swivel castor comes into position 9'.
  • the sieve belt 3 reaches 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, which partially run obliquely to the vertical spar 5 downwards.
  • 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 fed in at the point indicated by the 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 deflection roller 6 and the holder 9 of the steering roller 8 are now connected to the connection points of the oblique bars 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 position 3"'.
  • the sludge feed occurs again at the point of the arrow 20 and so a long filter zone 21 is created again.
  • the bearings of the lower deflecting roller 7 can remain at the connection points of the vertical spars 5, so that the lower deflecting roller is in its position 7 remains.
