Definitions

  • the present invention refers to the sector of centrifuges for oil extraction from an oily mixing which comes from the treatment of olives. Those centrifuges, being used in the oil industry, are known to skilled technicians also as "decanter”. In particular, the present invention refers to a horizontal centrifuge for oil extraction from an oily mixing due to previous rivendication No. 1.
  • oil will be obtained from an oily mixing which comes from an olive treatment and also from other oily products.
  • Oil will be obtained by means of extraction through centrifugation, which is based on the separation of liquids (essentially water and oil), which are contained in the oily mixing and which differ from each other for their specific weights in a centrifugal area.
  • centrifuges for oil extraction have a cilindrical drum with conical or cilindrical extremities; inlet heading with nozzles for the outlet of liquids (water and oil), a closing heading at the conical extremity with perforations for the sansa outlet; a coaxial scroll disposed in the internal part of the drum, which is foreseen to transport the humid solids to the outlet perforations which are disposed on the conical or cilindrical extremity, and a leading-in tube for the oily mixing from which oil will be extracted.
  • the centrifuges are able to work in a bimodal way, this is to say in two or three phases functioning. You will have a two phases functioning, when there are foreseen an oil outlet and an outlet for solid residual, this is to say for sansa and water. You will have a three phases functioning, when three outlets are foreseen respectively for each phase, this is to say for oil, water and sansa.
  • the general task of the present invention is to supply a horizontal centrifuge for the oil extraction, which offers a considerable better efficiency instead of the centrifuges already known.
  • the particular task of the present invention is furthermore to supply a centrifuge which doesn't suffer the inconvenience already mentioned above.
  • the horizontal centrifuge for the oil extraction from oily mixings consists of drum 1 supplied with two headings (2,3) and with a registrable leading-in tube (4) for the immission of the mixing, the tube (4) passes through the first heading (2) and ends in the internal part of the scroll (5), on the central axe of the same, the which forms a unique body with the helicoidal spirals, giving to the scroll the ability to expel the solids fed.
  • the central axe of the scroll (5) are provided with four perforations (7) and further four perforations (24), corresponding to two respective chambers (17,18) for the mixing's outlet which will be fed through an adjustable tube (4).
  • the diaphragm (8) with internal perforations is located near the closing heading (2) and allows the oil passing towards the outlet (12), in this way the machine works at two phases and allows the dam of oil, when the machine works at three phases.
  • the diaphragm (9) divides the two extraction chambers.
  • the diaphragms (10 and 11) are provided with perforations in the internal part which allow the four tubes (13) not to emulsify the liquid (oil) in the second chamber and not to suck the solid accumulated in that point to interrupt the spiral, the spiral's interruption allows the passing of the four tubes (13).
  • the perforations in the internal part of the two diaphragms (10 and 11) allow the oil passing, in order to be sucked from the tubes (13) which on their turn bring oil to the drum's outside (1).
  • the four tubes (16) allow to remove oil from the separation chambers (22), both when machine works at two phases, this is to say without addition of dilution water, and when machine works at three phases with addition of water.
  • the oil contained in the mixing leaks out from tube (13), while water goes back and goes beyond the diaphragm (9) and entering the separation chamber (22) to leak out from the heading level (12), going through the space between the external disk's diameter of the diaphragm 8 and the internal diameter of the drum 1.

  1. Centrifugeuse horizontale pour l'extraction de l'huile de pâtes huileuses, comprenant une carcasse, un bol rotatif monté à l'intérieur de cette dernière et une vis rotative avec un relatif axe central, montée dans le bol, bol et vis tournant à des régimes différents, et comprenant un diaphragme axial 9 délimitant dans la double paroi existante entre la vis et le bol deux chambres d'extraction de l'huile en pêchant respectivement dans les-dites première et deuxième chambres d'extracion; elle comprend également un tuyeau d'aduction de la pâte huileuse à l'intérieur del'axe central de la vis, qui, étant dotée de double paroi pour le soumettre au champ centrifuge généré par la rotation de la vis et du bol, et comprend une sortie pour le résidu solide de cette pâte huileuse. Cette double paroi étant fermée par des têtes d'entrée et de sortie, carctérisée par le fait que ces ouvertures de l'axe central de la vis sont distribuées en deux séries qui mettent en communication ces deux chambres d'extraction avec des chambres respectives 17-18 fournies en série dans l'axe central; le tube d'alimentation étant réglable pour pouvoir le placer aussi bien dans l'une que dans l'autre de ces chambres, faisant ainsi sortir la pâte dans le champ centrifuge de l'une ou de l'autre de ces chambres de séparation. Et que cette tête d'entrée qui possède de perforations 12 de sortie de liquide et que ces buses d'extraction radiale qui sont réglables de façon à ce que telle perforations de la tête d'entrée servent de sortie de l'huile dans le mode à deux phases et de l'eau dans le modes à trois phases. Ces buses radiales dans la seconde chambre d'extraction sont protégées d'un côté et de l'autre dans la direction axiale de la vis par des diaphragmes contre le cumul de résidus solides.
