Definitions

  • a sieving, screening, filtering or washing machine has a sieving machine frame and a yieldable sieving bottom which is fixed in sections to parallel drivable carriers which are mounted in the frame so as to be tippable by limited amounts about fixed axes.
  • the invention is particularly characterized in that all bottom carriers are continuously pivotally connected with one or two rods swinging in the same direction and thus can be driven in the same tipping direction.
  • the sieving zones are connected from the lower edge of the first carrier to the upper edge of the second carrier and from the lower edge of the second carrier to the upper edge of the third carrier, etc., thereby producing at the same time sieving zones of continuously changing width with differently low hanging curve-like arches or alternately tensioned locations or different tensions between all carriers.
  • Similar sieving, screening, settling or filtering processes are known in case of so-called two path sieving machines which use two carrier systems movable relatively to each other to form transverse or longitudinal sieving zones of continuously changing width with variable differently deep hanging curve-line archings or different tensions.
  • An object of the present invention is to provide a movement of transverse or longitudinal sieving zones by the use of one system sieving machine.
  • the basic difference of the present invention from prior art consists in that it does not use two swinging rods shifted by 180 as a drive for moving the two systems.
  • the present invention provides that all carriers are operated by a single system actuated by similar rod or rods and in one direction.
  • the present invention refers to a simple one system machine.
  • the present invention uses the consideration that in a parallelogram having the shape of a rhombus the diagonals connect the corners once by a longer stretch and once by a shorter stretch and when these corners are made movable or swingable the sides of the parallelogram can be shifted. Then the diagonals are in one position long and in the other short, depending upon the selected position.
  • a very useable solution for the operation of elastic sieving bottoms consists also in that the elastic sieving bottoms, for example, are actually rolled up at an end of the carriers with round cross-sections opposite the transportation direction.
  • This also provides a tensioning and an untensioning of the individual zones with the additional advantage that the sticking of the wet sieving goods upon the carriers which is always feared, is eliminated, since it is prevented by the sieving mat rolling on and off upon the upper side of the carriers.
  • the basic principle of the machine of the present invention makes possible the use of the correspondingly cut elastic sieving bottoms also in case of multiple separations, filtering requirements or washing processes.
  • P10. 1 is a diagram showing a sieving method.
  • FIG. 2 is a diagram showing the basic solution of the present invention.
  • FIG. 3 is a diagrammatic side view of a device of the present invention.
  • FIG. 4 is a side view of the sieving machine of the present invention.
  • FIG. 5 is a top view of the machine of FIG. 4.
  • FIG. 6 is a partial side view of the machine.
  • FIG. 7 is a section through a somewhat differently constructed machine.
  • FIG. 8 is a diagram showing the use of two machines with a common drive.
  • FIG. 9 is a side view of a double deck sieving machine having the sieving principle of the present invention.
  • FIG. 10 is a diagrammatic view of an air filter.
  • FIG. 11 is a perspective partial view of a side sealing device.
  • FIG. 12 is a diagrammatic view illustrating the use of the sieving machine principle of the present invention in a washing vat.
  • FIG. 1 shows in a simplified form the principle of the new sieving method with elastical sieving bottoms by the use of one movable system.
  • the mat connected to a fixed point F has a tensioned shape or an untensioned curved shape B if it is connected to a reciprocating point a, b.
  • FIG. 2 shows the principle of the new solution of the present invention wherein a single moving system makes it possible to produce tension and untensioning of the intermediately connected sieving mat and to hold movable all connecting points of this sieving mat.
  • the tipping carriers located upon rotary points D have connections for the sieving mats at their upper as well as lower sides so that each sieving mat S is connected once to the lower side of the carrier and once to the upper side of the carrier.
  • the tubular carriers 1 having connecting profiles 2 and 2 are shown in the two end positions into which they are placed by swinging levers 3 and rod 4.
  • the rod 4 can be actuated by excenters and connecting rods or by pneumatic, hydraulic or electromagnetic hoisting drives (not shown).
  • the present invention suggests that a preferably elastic covering cap be placed over the carriers upon the side on which the sieving goods run.
  • the cap consists preferably of the same material as the actual sieving mats. It is also possible to pull an undivided mat over the entire length of the sieving surface and to attach it doubly upon the upper and lower sides of the carriers, whereby then the lengths 6 covering the carriers will have no holes, while the lengths or widths located between the carriers will constitute the actual sieving bottom.
  • Balancing masses 11 are excentrically mounted with their centers of gravity shifted by and have the purpose of balancing the run of the sieving machine.
  • Covering frames 12 are located above the sieving surface in the usual manner. Their purpose is to provide a seal and hold back the very highly accelerated sieving grains.
  • FIG. 6 illustrates in detail the locations of the rod 4, the swinging levers 3, the tube carriers 1 and the connecting profiles 2 and 2'.
  • FIG. 7 also shows the core of the machine of the present invention with the rod 4, the swinging levers 3, the carrier supports 13 and the tube carriers 1.
  • FIG. 8 shows diagrammatically the construction of the present invention wherein two machines are provided with a common drive.
  • the central arrangement of the transporting band 14 makes possible a great output.
  • the excenter connection running while shifted by 180 provides a good balancing of the masses.
  • FIG. 9 A sieving machine of the present invention having a double deck is shown in FIG. 9.
  • FIG. 10 An air filter in an air withdrawing channel is shown by way of example in FIG. 10. Dirty air is introduced through the inlet 14 of the filter in front of the intermediate opening of filter surfaces of the present invention. Dirt particles of the air are withdrawn through the outlet conduit 15 while clean air is removed through the outlet 16.
  • FIG. 11 shows a side sealing 17 particularly for use on sieving machines and described in detail in the copending German patent application No. P 21 32 163.1. In this construction there is a rhombus-like shifting movement of the frame of this sealing 17.
  • a device comprising a length of yieldable sieve bottom, a plurality of parallel spaced pivoted carriers forming at least one section, at least one movable rod, means pivotally connecting said rod with said carriers, to provide a uniform swinging movement of said carriers, said sieve bottom extending along said carriers and being connected to a lower edge of one carrier and the upper edge of an adjacent carrier, then to a lower edge of the following carrier and so on along all carriers,
  • said sieve bottom forms sieving zones between said carriers of variable shapes during the actuation of said carriers.
  • a device in accordance with claim 1, comprising a machine frame and a plurality of carrier sections carried by said frame.
  • said means comprise swingable levers connecting said rod with said carriers, said rod being located upon one side of said carriers.
  • a device in accordance with claim 1 the machine serving as a settling or washing machine and having a container, the device being located in said container in an inclined position.
