Definitions
- Gearing in screw presses The gearing is used in screw presses in front of the entrance to the screen area.
- the object of the invention is to prevent these blockages.
- the screw presses work with cylindrical bar screens (5).
- the screw starts in the region of the inlet, the housing having a cylindrical transition from the inlet box until the beginning of the screen screen.
- this cylindrical transition is provided with axial teeth (6) in an angle favoring the shear and shear action for the worm rotating above it.
- the teeth form a narrow gap to the screw (4).
- the 4-6 mm deep slots between the teeth and the teeth have a width of 5-20 mm.
- the gap between the teeth and the screw is 0.3-0.5 mm.
- Teeth and piebalds are armored on the surfaces.
- the gearing is used in screw presses in front of the entrance to the sieve area.
- long-fiber components such as poultry feathers, straw, solid hay or binders such as strings, ropes or the like are introduced into the machine with the mixture of liquid and solids to be separated, they can become lodged over the screw flights. Between the cylindrical transition and the rotating screw, these substances are compressed and thus reach the inlet region of the rod screen. Due to the surface provided with sieve gaps in the sieve, this compression dissolves after a few centimeters. Since abrasive components are included in the feed to Preßschneckenseparator, it comes through the pressures occurring to excessive wear in the inlet region of the rod screen. All at once get larger amounts of long-fibered parts in the
- the object of the invention is to provide a robust device for avoiding compacting material and for preventing blockages even before the area of entry of the mixture of liquid and partly long-fiber solids into the sieve to be separated.
- the long parts are to be largely crushed.
- it must be prevented that the inlet area of the screen screen and the screen itself are damaged by a compression of fibers and abrasive components between the screw and the cylindrical transition.
- the cylindrical transition in the housing between inlet box in the area of Preßschneckenseparators and the beginning bar screen for this purpose is changed constructively.
- a feature of the invention is to obtain a shearing action on as many edges as possible, over which the worm moves with a narrow gap, which cuts all disturbing long-fiber solids and exerts a thrust action in the axial direction.
- the cylindrical transition is provided with a plurality of axially arranged teeth at an angle such that opposite the cutting edge of the screw, the edges of the teeth form an angle and so a pushing and cutting action is achieved.
- This angle can be performed differently in different applications according to the feed to be separated and the long-fiber fractions contained therein.
- the arrangement of the teeth in the axial direction is sufficient, as shown in the following example.
- the 4 to 6 mm deep teeth and the slots have a width of 5 to 20 mm and the gap between the armored webs and the screw is 0.3 to 0.5 mm.
- FIG. 1 shows a partial section through a screw press.
- the liquid to be separated from the partly long-fiber solids (1) is introduced into the machine via a pipe socket (2).
- the largely dewatered solid is pressed into the region of the hollow cylindrical plug (7) and discharged via the discharge regulator (8) as a moist crumbly solid (9). About the nozzle (10) leaves the separated liquid (11) the machine.
- Figure 2 shows the same Preßschneckenseparator. For a better view, the cuts have been extended so that the cylindrical transition (6) and the bar screen (5) can be seen without the screw concealing this area.
- FIG. 3 shows the section A-A indicated in FIG. 2 and thus the 36 teeth (12) arranged on the circumference of the cylindrical transition (6) with the slots of the same width lying therebetween.
