Definitions

  • the invention relates to a screw press with two screws lying next to one another, consisting of a housing, an inlet-side loading opening, an outlet-side shaping or briquetting head and two screw shafts driven by a gear, which are composed of individual screw elements provided with a core cylinder, the housing is divided into the length of the screw elements corresponding housing elements 3-6, between which there is a throttle device 19 which blocks the free cross section of the screws with the formation of a passage gap.
  • Screw presses are already known (DE-A-1 944 642) in which a single-screw design is used for processing the material to be treated, in which both the screw and the housing are divided into individual elements.
  • a throttle device is installed between two elements, the through opening of which is delimited by a tapering inner and outer surface.
  • the outer surface is designed to be axially displaceable.
  • the relatively large axial space requirement between two elements is disadvantageous.
  • only a pressing of the material without substantial heating of the same is possible with an annular nozzle-like design of the through opening.
  • any material to be processed can be minced, dewatered and compacted in a compact manner bring.
  • the throttle is a throttle disc 19 located between two housing elements, which constricts the free cross section of the screw flights of the screws 10, 11 to form an adjustable throttle gap on the circumference of the core cylinder of the screw and is formed in two parts, whereby with one part 20 a bottom throttle gap and with the other part 21 a top throttle gap is adjustable and the other part has a width that is at least equal to twice the core diameter and a pitch.
  • the two-screw press shown in FIGS. 1 and 2 has a housing 1 which is composed of housing elements 2, 3, 4, 5, 6, the housing element 2 deviating from the other housing elements 3-6 and having a loading opening 7.
  • the housing elements 2-6 are connected by screws 8 or 9 bolts.
  • Screw elements 14 are attached to a worm shaft 12, 13, the length of which corresponds to that of the housing elements 2-6. They can be single or multi-course and have the same or a different pitch. The sequence of the screw elements 14 and their number can be adapted to the respective material to be processed.
  • a tensioning shaft 15 is screwed in, which extends through the worm elements 14 to the end of the last worm element and carries a tensioning flange 16 at its end, is screwed into the tensioning screws 17, which are in a in the last worm element 14 supported clamping head 18 are mounted and allow the clamping of the clamping shaft 15 and thus the screw elements 14 by turning.
  • a throttle disc is arranged between the individual housing elements 3-6, the design of which can be seen in FIG. 3.
  • the throttle disk 19, with which a narrow gap is formed around the core diameter of the screw elements 14, is composed of two parts 20, 21, which have corresponding bores 22 or slots 23, with the aid of which they pass through between the housing elements 3-6 Bolts 9 are held.
  • the slots 23 in the part 21 on the apex enable the gap between the throttle disk 19 and the core diameter of the screw elements 14 to be set differently.
  • the throttle disk 19 enables the most varied materials to be processed practically with the same screw press.
  • the housing elements 3-6, which are, for example, in two parts in FIGS. 1 and 2, and the screw elements 14 need not be changed. An adaptation to different types Materials can be achieved in a simple manner by changing the housing 1 and, accordingly, the screws 10, 11 by adding or removing further housing and screw elements.
  • the two worm shafts 12, 13 protrude from the housing 1 on the inlet side and extend through a gear transmission and are supported on an axial bearing 24.
  • the support can be done in various ways, e.g. B. by thrust roller bearings. It is essential here that the force exerted by the two worm shafts 12, 13 on the axial bearing 24 is diverted to the housing 1 via tie rods 25 which are fastened in the housing 1, as a result of which a self-contained force flow is achieved.
  • the transmission 26, preferably a gear transmission, serves to couple a drive motor and to drive the two worm shafts 12, 13 via the transmission 26.
  • An expansion pressure sensor 27 is provided between the housing 1 and the gear 26.
  • the worm shafts 12, 13 passing through the expansion pressure transducer 27 are supported therein by means of bearings. If spreading forces occur on the worm shafts 12, 13, these are supported via their bearings on the spreading pressure sensor 27.
  • the expansion pressure transducer 27 is not supported on the housing 1 or on the gear 26, but is guided loosely on the tie rods 25.
  • a shaping or briquetting head 28 is attached to the outlet side of the screw press. The material emerging from the screw press can thereby be given a specific shape. Guides 29 serve to discharge the ejected material.
  • One or more openings 30 can be arranged in the housing elements 3-6 at the top and / or at the bottom. There, juice or steam that collects or flows out during the pressing process can be sucked off and sent for further treatment. It is also possible that juice squeezed out of the openings closer to the loading opening 7 and steam can be canceled at the openings further away. In this regard too, the screw press can be adapted to the respective requirements without major changes.
  • Fig. 4 is a plant for processing green mass, z. B. grass.
  • the screw shafts 12, 13 of the screw press are driven via the gear 26 by a motor 31 which is coupled to a second motor 32.
  • the juice squeezed out of the green mass is drawn in by a peristaltic pump 33 and conveyed into a flocculation container 34.
  • the flocculant is added there by means of a schematically indicated device 35, the gel which is formed in this case being discharged through a line 36 and the residual liquid through a line 37.
  • the two further openings 31 are used to extract damper by a fan 39 or a vacuum pump via a line 38.
  • the screw press described thus solves the problem of drying materials on the one hand and briquetting on the other hand. Liquids and vapors can be easily extracted and processed separately. It is essential that the press described consists of standardized elements, i.e. H. can be assembled from the housing elements 2-6 and the screw elements 14, and the corresponding number of standardized throttle disks 19 can also be used. During the operation of such a press, it has surprisingly been found that the power consumption of the screw press is comparatively low, so that less power is required compared to other drying processes, and that a multitude of functions can be solved with the described method and the described screw press. Mechanical drying is of particular importance. H. without the addition of heat, and the hygienization achievable with it, d. H.
  • the adaptation of the screw press to the different materials to be processed and which vary greatly in composition is determined by the number and arrangement of the screw elements 14, e.g. B. with opposite slope, and - with two screws 10, 11 - by the mode, z. B. with up or down counter-rotating direction and with right or left rotation of both screws, quickly and easily achieved.
  • the material of the screw elements 14 is expediently resistant to abrasion, e.g. B. high-alloy steel, which can still be fitted with hard metal on heavily wearing parts.
