Definitions

  • the invention relates to an inverting filter centrifuge for separation of liquid-solid mixtures with a rotating drive Centrifugal drum, with one on the centrifugal drum arranged, reversible filter cloth, with a filtrate housing for receiving and discharging the liquid-solid mixture by centrifuging in the centrifugal drum liquid filter, with the filter cloth a solid housing for receiving and discharging the liquid-solid mixture while rotating the centrifugal drum with the filter cloth separated solid (Filter cake) and with the edge of the centrifugal drum in the Area of the filtrate housing and the solid housing surrounding Annular gap.
  • a gas inlet connector 51 provided on the solid housing 11 a compressed gas source (pressure pump) connected in the direction of the arrow a gaseous medium, for example air or a introduces inert gas into the solid housing 11.
  • the one in the solid housing 11 overpressure used can be, for example, 5 to 50, preferably 10 to 30 mbar.
  • the filtrate housing 10 has a further nozzle 52, which in the simplest case is open to the atmosphere.
  • That discharged from the solid housing 11 via the exhaust line 59 Gas can be reprocessed. If you are with a sealing gas flow works in the opposite direction, so the gas not from the solid housing 11, but from the filtrate housing 10 subtracts - with closed valves 54, 57 the valve 55 opened and the gas also for the purpose of processing inserted into the exhaust pipe 59. In this case for example the introduction of the gas via the pipe socket 51 into the solid housing 11, the pipe socket 52 is tightly closed.

Claims (13)

  1. Centrifugeuse à filtre réversible servant à séparer des mélanges liquide-substance solide, comportant un tambour de centrifugation (16) entraíné en rotation, une toile filtrante réversible (22) disposée sur le tambour de centrifugation (16), un boítier (10) pour le filtrat servant à recevoir et évacuer le filtrat liquide séparé du mélange liquide-substance solide par centrifugation lorsque la toile filtrante (22) est insérée dans le tambour de centrifugation (16), un boítier (11) pour substance solide servant à recevoir et évacuer la substance solide (gâteau de filtre) séparée du mélange liquide-substance solide sous l'effet de la rotation ultérieure du tambour de centrifugation (16) avec la toile filtrante (22) retroussée, et une fente annulaire (15) qui entoure le bord du tambour de centrifugation (16) dans la zone du boítier (18) pour le filtrat et du boítier (10) pour la substance solide, caractérisée en ce que sur la centrifugeuse à filtre réversible sont prévus des dispositifs de protection (51, 52, 62, 63, 64, P) sous la forme de dispositifs de production de gaz de blocage, à l'aide desquels peut être produit, dans la fente annulaire (15) entourant le bord du tambour, un courant de gaz de blocage, qui agit dans deux directions et empêche un transfert indésirable de substances gazeuses, liquides et/ou solides en direction du boítier (10) pour le filtrat et/ou du boítier (11) pour la substance solide, par le fait qu'une surpression ou une dépression peut être produite directement dans le boítier pour le filtrat ou dans le boítier pour la substance solide.
  2. Centrifugeuse à filtre réversible selon la revendication 1, caractérisée en ce que les dispositifs de protection comprennent une pompe (P).
  3. Centrifugeuse à filtre réversible selon la revendication 2, caractérisée en ce que la pompe (P) est reliée par l'intermédiaire de moyens de guidage et de commande (50, 52, 53, 54, 55, 57) aux boítiers (10, 11) prévus pour le filtrat et la substance solide et qu'au choix une dépression est produite dans l'un de ces boítiers (10; 11) de telle sorte que le gaz de blocage pénètre dans l'autre boítier respectif en passant par la fente annulaire (15).
  4. Centrifugeuse à filtre réversible selon la revendication 2, caractérisée en ce que la pompe (P) est raccordée par l'intermédiaire de moyens de guidage et de commande (62, 63, 64) à la fente annulaire (15) qui entoure la paroi du tambour, et produit directement dans cette dernière le courant de gaz de blocage.
  5. Centrifugeuse à filtre réversible selon la revendication 4, caractérisée en ce que la pompe (P) produit dans la fente annulaire (15) deux écoulements (I, II) d'un gaz de blocage, dont l'un est dirigé dans le boítier (10) pour le filtrat et dont l'autre est dirigé dans le boítier (11) pour la substance solide.
  6. Centrifugeuse à filtre réversible selon la revendication 1, caractérisée en ce que le gaz de blocage est de l'air ou un gaz inerte.
  7. Centrifugeuse à filtre réversible selon la revendication 1, caractérisée en ce qu'une garniture d'étanchéité (41) est disposée dans la fente annulaire (15) entre le bord du tambour rotatif de centrifugation (16) et une partie fixe (14) du carter de la machine.
  8. Centrifugeuse à filtre réversible selon la revendication 1, caractérisée en ce qu'il est prévu une conduite de gaz d'échappement (59), dans laquelle peut être introduit le gaz de blocage qui sort du filtre du boítier pour la substance solide (10, 11).
  9. Centrifugeuse à filtre réversible selon la revendication 8, caractérisée en ce que le conduit de gaz d'échappement (59) contient une soupape de maintien de pression (61).
  10. Centrifugeuse à filtre réversible selon la revendication 1, caractérisée en ce qu'il est prévu une conduite d'oscillation de gaz (53) comportant une soupape de blocage (54) entre le boítier (10) pour le filtrat et le boítier (11) pour la substance solide.
  11. Centrifugeuse à filtre réversible selon les revendications 2 et 10, caractérisée en ce que la pompe (P) est disposée dans la conduite d'oscillation de gaz (53).
  12. Centrifugeuse à filtre réversible selon la revendication 1, caractérisée par un filtre (58) pour la substance solide pour le courant de gaz de blocage qui sort du boítier (11) pour la substance solide.
  13. Centrifugeuse à filtre réversible selon la revendication 1, caractérisée par un séparateur de liquide (91) pour le courant de gaz de blocage qui sort du boítier (10) pour le filtrat.
