Definitions

  • the present invention relates to a reamer for a Rundabsetzbecken and provided with such a reamer round heel basin.
  • scraper bridge is placed on the central structure and the pelvic crown of the settling tank and driven laterally or centrally with a chassis.
  • the present invention comprises the finding that the very high demands on the construction and machine technology have a disadvantageous effect on settling tanks with the known reamers mentioned at the outset.
  • the present invention has recognized that - in order to achieve a good evacuation effect with the known scavengers - the pelvic floor of the sedimentation tank with high accuracy and the pelvic crown of the settling tank must be carried out horizontally. So that the bending of the bridge is as small as possible or remains within the permissible range, strong constructions with a correspondingly high weight must be selected for the bridge.
  • the chassis has a high abrasion force on the Maschinenrlaufbahn on the pelvic crown.
  • the pelvic crown must therefore be refined or treated with expensive technology, e.g. Abrasion-resistant coating or stainless steel cover.
  • the track In order to be able to ensure winter operation in this context, the track must finally also be provided with tracing heating.
  • the reamer according to the invention is

  • FIG. 1 shows an embodiment of a scraper 7 according to the invention in a Rundabsetzbecken 1 in a plan view.
  • the Rundabsetzbecken 1 has a pelvic floor 1a and a pool wall 1b, see also Fig. 2.
  • Below the basin sole 1a is a feed pipe 2 for a sewage activated sludge mixture.
  • drainage channels 5 are formed, which are radially inwardly directed, with distance to the pelvic floor 1a on this partially extending immersion tubes 4 (or a Ringtauchrohr with smaller pelvis diameter (not shown)) with the defined from pool bottom 1a and pool wall 1b working space the Rundabsetzbeckens 1 are connected.
  • the reamer 7 On the pelvic floor 1a a reamer 7 is formed.
  • the reamer 7 consists according to the figures 5-7 of individual reamer elements 20.
  • the reamer elements 20 in turn consist of redesignrschilden 16 with a rubber lip 15th for sealing and brackets 14.
  • the reamer shields 16 are supported on horizontal brackets 14.
  • the brackets 14 also carry webs 17, the holes 17 a, through which in turn a rope or a chain 18 is guided.
  • the rope 18 connects the individual reamer elements 20 with each other to form a link chain or a chain chain 7.
  • the reamer shields 16 shown in greater detail in FIGS. 6 and 7, together with the holders 14, can have the shapes of an L, U or T in section. In order to avoid a breakdown of the mud through the link chain 7, the reamer shields 16 are arranged overlapping.

As the effluent flows blasted in the outward direction toward the pool wall 1b, the heavy solids settle towards the bottom 1a. The clear water is collected with the perforated dip tubes 4 and discharged via the gutter 5 on the pool wall 1b and the drain pipe 6. The bottom sludge is pushed into the sludge funnel 13 with the link chain scraper 7 according to the invention. From there it is withdrawn by means of the sludge exhaust pipe 13a.

Abstract

La présente invention concerne un racleur (7), notamment un racleur pour boues de sédimentation, pour un bassin de décantation rond (1), notamment pour la séparation des phases de matières solides et de liquides dans des stations d'épuration. Le racleur (7) se caractérise par au moins deux éléments de racleur (20) de préférence mobiles l'un par rapport à l'autre.
