Definitions

  • the invention refers to a deshydrating screw press with two helical elements, which avoids partial interference zones of the spirals on the product to treat.
  • the screw presses are used to deshydrate fibrous materials containing liquid; they are particularly used in the sugar beat treatment, in fodder deshydratation, to extract oils and produce meals for fodders from food stuff recovers such as fish and other.
  • the said presses use two or more helical elements which let the product advance from an end, pressing it inside a filtering cage from which the liquid gets out steadily, while the anhydrous residue is discharged from the other end. This causes a bicylindrical interference space of the spiral filtering cage, which gives rise to non-interference zones, as well as other zones with limited interference of the spirals.
  • This intervention difformity and even of non-intervention of the spiral does not grant a uniformity of pressure of the product and causes losses of delivery.
  • GB-A-677 794 discloses a deshydrating screw press with two helical elements with constant profile as defined in the pre-characterising part of claim 1.
  • the product to deshydrate in advancing movement is pressed by the rotating motion of two screw elements with conical shaft 1 and also conical spiral 2 - total and regular - to operate in a correspondence space to wall limit of the filtering cage 3.
  • the helical elements with regular total conical interference are used side by side, since the lifting upwards of the spiral 2 is in them in accordance with a like section reduction 4 of its shaft 1, each spiral is allowed to work with profile continuity up to wall limit of the shaft of the other helical element, thus avoiding zones of either no or limited interference on the treated product in the intermediate space between the shafts.
  • the filtering cage used for the press with two helical elements consists of two components 5 and 6 connected on slanting converging lines 7 and 8 fitted on interference limit of the two intersected spirals.
  • FIG. 1 is the vertical longitudinal section of the press with side view of a helical element to point out the conical interference spiral which operates up to wall limit of the filtering cage.
  • Fig. 2 is a partial view of horizontal longitudinal section of the press, with view from above of the two flanked helical elements to show the intermediate zone between the two shafts where the interference of the two spirals can be noted, each one of which is working up to wall limit of the other one's shaft.
  • Fig 3 is a view of the press transversal section to show the interference fields of the two spirals.
  • motor 9 For the press operation, motor 9 is started which, by means of transmission 10 with pulleys 11 and 12, transmits the movements, through reducer 13 on shafts 14, to the helical elements with conical shafts 1 and conical spirals 2.
  • the biconical filtering cage is kept, by the modular ping U-bolts 15 and 16, in the frame 17 on base 18 and is contained in carter 19 complete with inspection lids 20.
