Definitions

  • a first embodiment thereof is provided with a suction box co-displacing with a filter cloth and making a reciprocating movement.
  • side boxes are situated close to a side edge of a carrier belt for the filter cloth, and the liquids are sucked through channels in the carrier belt to the suction boxes.
  • This latter embodiment has the advantage over the above mentioned first embodiment that the suction boxes can be of relatively simple embodiment, since they are placed in stationary position. Due to the arrangement close to the edges the suction boxes are readily accessible for inspection, cleaning and maintenance.
  • the present invention provides a device for separating liquid and solid material from a mixture, comprising:
  • a carrier belt for supporting the filter cloth with the mixture thereon, wherein the carrier belt is optionally provided with one or more openings close to at least one of the side edges or at least eccentrically thereof;
  • a suction box arranged under the support construction and/or on the side of the carrier belt and connecting to the optional openings in the carrier belt for extracting liquid from the mixture.
  • the carrier belt is embodied in plastic, this being recommended for particular chemical compounds since it does not give off any colour to the separated liquid and/or solid material.
  • the carrier belt is of rubber, since rubber is extremely wear-resistant and has a long lifespan.
  • FIG. 1 shows a view in perspective of a preferred embodiment of the device according to the present invention
  • FIG. 2 is a cross-sectional view along the preferred embodiment shown in FIG. 1;
  • FIG. 3 shows a cross-sectional view of a further preferred embodiment of the device according to the present invention.
  • a filter cloth 2 and a rubber belt 3 placed thereunder and provided with channels 4 are trained round rollers 5 , 6 , at least one of which is driven.
  • suction boxes 7 , 8 Disposed along the edges in stationary position under carrier belt 3 are suction boxes 7 , 8 which are provided on the underside with a discharge connection 9 respectively 10 for discharging the liquid sucked through filter cloth 2 , while the suction boxes are provided on the top side with suction connection 11 respectively 12 , whereby a further separation between volatile constituents of the liquid and less volatile constituents thereof also takes place in suction boxes 7 , 8 .
  • the carrier belt is provided on both edges with heel parts 16 respectively 17 in order to ensure that the liquid enters the openings 13 via the arrows.
  • the carrier belt is sealed on the upper side relative to the fixedly disposed construction 20 using seals 18 respectively 19 .
  • the suctions boxes 37 , 38 are arranged in stationary position on the sides of carrier belt 3 , wherein the suction boxes are again provided on the underside with discharge connections 39 respectively 40 for discharging liquid sucked through filter cloth 2 , said boxes being provided on the top side with suction connections 41 respectively 42 whereby a separation between volatile constituents of the liquid and less volatile constituents thereof also takes place in suction boxes 37 , 38 .
  • the carrier belt lies at both sides on seals 44 , 45 of a wear-resistant material, such as for instance teflon, which is situated on supports 46 , 47 fixed to suction boxes 37 , 38 .
  • channels 43 , 44 are made in the outer ends of the carrier belt and/or heel parts 16 respectively 17 , which channels connect onto elongate opening parts 50 , 51 on the side of suction boxes 37 , 38 .
  • shoulder parts 48 are situated on the sloping upper part of the suction boxes respectively 49 of a wear-resistant material with a low coefficient of friction, such as for instance teflon, on which the filter cloth 2 supports and along which this cloth is pulled.
  • suction boxes are disposed in stationary position under and on the side of the carrier belt. This embodiment is therefore a combination of the embodiments shown in FIGS. 1, 2 and 3 .
