Definitions

  • the present invention relates to an arrangement in a screw press with horizontal screw elements having mutually co-operating screw threads for conjointly feeding the material to be conveyed through the press for pressing out liquid therefrom, and being conjointly enclosed by a relatively tight-fitting press casing having openings for straining liquid from the material conveyed through the press.
  • the present invention aims at solving the above-­indicated problems by relatively simple means.
  • the present invention is characterized in that the press casing encloses three screw elements of which a first and a second screw element are disposed side by side at the bottom of the press casing and delimited at the bottom by a common, lower press casing part, while a third screw element is disposed at the top of the press casing parallel to, above and midway between said first and second screw elements and de­limited by one or a pair of upper press casing parts.
  • first and second screw elements are disposed at the bottom of the press. In this way, it will be easy to modify existing presses while retaining the essential parts thereof. In addition, it is possible, when feeding material into the press, to ensure an even supply to all three screw elements at the very inlet end of the press by supplying the material to the third screw element and, respectively, on opposite sides thereof to the subjacent first and second screw elements.
  • a horizontal screw press 10 having a lower frame 11 resting on a horizontal supporting surface 12.
  • the screw press comprises a press casing 13,14 divided into two parts and having a statio­nary bottom part 13 and a removable top part 14.
  • the press casing is provided in a conventional manner (not shown in more detail) with an inner surface 15 forming a straining surface throughout the entire circumference of the press casing and throughout the entire length thereof.
  • Longitudinal clamping strips 16,17 are provided on opposite sides of the press casing at the joint between the press casing parts 13,14.
  • longitudinal, central strips 18,19 at the interspace 20 between two internal, parallel working chambers 21,22 i.e. a lower strip 18 extending upwards into said interspace, and an upper strip 19 extending downwards into said interspace 20.
  • the screw elements 23,24 In the working chambers 21,22, there are mounted two parallel screw elements 23,24. None of the illu­strated screw elements has a straining surface, but for increased drainage of liquid, the screw elements may be provided with a straining surface, e.g. on the screw trunks 23a,24a of the screw elements. Option strictlyally, there may also be provided straining surfaces on the screw threads 23b,24b of the screw element.
  • the press casing 13,14 is supported in upper and lower bridge sections 13a,14a which, at their outer ends, are adjustably clamped against each other by clamping means 25,26.
  • the press according to Fig. 1 is modified by a reconstruction of the top part of the press.
  • the bottom part 13 remains unaltered with the associated clamping strips 16, the lower central strip 18 and the bridge sections 13a.
  • the two screw elements 23,24 and the lower frame 11 remain the same.
  • the three screw elements 23,24,30 define three overlapping thread portions 35,36,37 (hatched portions) and an intermediate triangular space 38 defined between the peripheries of the three screw elements.
  • the screw trunks 23a,24a, 30a are indicated by dashed lines, while the peripheries of the screw threads 23b,24b, 30b are indicated by full lines. It is evident that the material is fed through the press in the interspaces between the screw threads of the rotating screw elements and the adjoining stationary press casing but also at the hatched thread portions where the screw threads of the screw elements overlap each other and at the space 38 centrally defined between the screw elements.
  • the first screw element 23 is rotatable anticlockwise as indicated by the arrow 39, while the second screw element 24 and the third screw element 30 are rotatable clock­wise as indicated by the arrows 40 and 41, i.e. in a direction opposite to the direction of rotation of the screw element 23. This results in a forced or positive feed of material.
  • screw elements 23,24 rotate in the same direction, and the screw element 30 rotate in the opposite direction with respect to the screw elements 23,24. Further, it is possible to have the screw elements 23,24 rotate in mutually opposite directions, i.e. in directions opposite to those shown in Fig. 2.
  • a stationary section or bottom part 42 extends through only one third of the press casing while two further sections 43,44 form the top parts of the press and together extend through the remaining two thirds of the press casing.
  • each of the sections 42,43,44 can be designed substantially identical.
  • the upper two sections 43,44 may, for instance, be hingedly connected at the bottom to the section 42 at 45,46, while they can be clamped together at the top by clamp­ing means corresponding to one of the clamping means in the embodiment according to Fig. 1.
  • the hinge connections are provided at 45,46 in a manner to make the upper sections 43,44 easily dismountable from the press.
  • the screw casing diameter is widened at the inlet end, but may alter­natively be constant throughout the entire length of the screw.
