Definitions
- the invention relates to a method for operating a Mixer and shredder for waste, especially for biodegradable waste.
- Another object of the invention is a shredder working according to the method and Mixer.
- the invention is based on the subject of AT 402 638 B, which already has a device for shredding and Mixing waste, especially biodegradable, Waste is known.
- This facility essentially exists from a container, in the interior of which are arranged in pairs Screw conveyors are arranged, an upper one Screw conveyor pair parallel and side by side in mutual distance is arranged and also a lower Screw conveyor pair, which is also coaxial with that upper pair of screw conveyors is driven in rotation in the container.
- the crushing and mixing operation takes place in the known Patent specification in the manner that an upper screw conveyor in the same direction as the screw conveyor below is driven, but that the direction of rotation of these two superimposed screw conveyors with respect to the Filling operation and discharge operation not changed can be. All screw conveyors of the well-known facility convey the mix both in the filling and mixing operation, as well always in the same direction of rotation, even in discharge mode.
- the filling opening becomes, for example, the left side the screw conveyor is driven clockwise while the right side of the augers, which are located one above the other in the Is driven counterclockwise.
- the filling plant is designed so that the material itself distributed as homogeneously as possible in the container. After filling the The operation of the screw conveyor takes place in the container same, previously mentioned direction of rotation, so that Material is circulated in the container. It will be here guided along the ground by the lower screw conveyors one end of the container is conveyed upwards and over the upper snails again parallel to the ground to the other End of the container conveyed back.
- the known device For changing from filling and mixing operation to discharge operation the known device provides that the near-ground, lower Augers of the screw conveyor are divided and that the section is assigned its own drive, the is capable of these partial screw conveyors in an opposite sense to the Main conveyor screws flanged axially there can be. It is important that the main screw conveyor of the known equipment always the material - both in the mixing and Filling operation, as well as in the discharge operation - in one Promote direction of rotation, arranged by the front Discharge opening is facing away. During the filling and Mixed operations promote the divided screw conveyors in the same direction as the axially flanged to it Main screw conveyors. In the discharge mode, however, only the direction of conveyance of these partial screw conveyors by 180 degrees twisted, so that this is still in mixed operation circulating flow of the mixed material each a partial flow remove and against the - then open - front Promote discharge opening.
- the disadvantage of the known device is that the Division of the screw conveyor near the ground into two Partial screws and the arrangement of two separate Drives for these partial screw conveyors with high Machine expenditure, high maintenance expenditure and accordingly is also associated with high manufacturing costs.
- the invention is therefore based on the object of a method to operate a known device for shredding and Mixing waste and one working according to the process Continuing education so that they are essential works more cost-effectively, more simply and more reliably.
- An essential feature of the invention is that in a first Process step for the purpose of filling and Mixed operation which are arranged approximately one above the other Screw conveyors on one side, for example, clockwise and the other side is driven counterclockwise and that the direction of rotation of the superimposed screw conveyors are exchanged in such a way that now, for example, the right side counterclockwise and the left side is driven clockwise.
- a constructive embodiment of such a device provides for an improvement in material diversion from the lower conveyor screw pair to the upper conveyor screw pair done by a so-called conveyor plate.
- This conveyor plate ensures that against the front side (drive side) pressing material flow of the mix does not have this flange loaded, but it is redirected to this conveyor plate and sent towards the top where it enters the lead-in area of the upper pair of screw conveyors.
- This on the drive end of the container arranged conveyor plate has the further advantage that in Discharge this conveyor sheet for a complete Emptying the container ensures. That on this conveyor plate material is removed from the top, and brought into the area of the lower pair of screw conveyors, see above that it is caught by the lower pairs of screw conveyors and on simple way on the opposite end arranged discharge opening is supplied.
- the result is essential advantage that with two drives (compared with the four drives according to AT-PS 402 638) are essential better mixing and grinding performance in such a Establishment is reached.
- the device according to the invention consists essentially of a container 1, which according to Figures 1 to 4 an elongated Has shape and a conical cross section downward tapering profile shape.
- a container 1 which according to Figures 1 to 4 an elongated Has shape and a conical cross section downward tapering profile shape.
- Screw conveyor pairs arranged in the container 1
- an upper Auger pair 6.7 approximately aligned and oblique to each other offset to a lower pair of screw conveyors Screw conveyors 12, 13 are arranged.
- a vertical one Longitudinal center line 46 divides the container into two Container sides.
- the container is filled via an upper filling opening 2, the limitation of which is indicated approximately by the arrows 3.
- the mixed material 19 filled via the filling opening 2 is from the augers 6,7 and 12,13 circulated and here crushed.
- the shredding takes place according to FIG. that each screw conveyor 6, 7, 12, 13 on its screw blade 26 is equipped with a large number of knives 27, which Rip knife on its outer edge with a housing-fixed the container wall 29 attached counter knife 28 combs. Any material between these two knife gaps is crushed and homogenized. Also done a crushing and homogenization through the whole Mixing process according to Figures 1 and 2.
- the mixing container has on the outside on the Container wall 29 holder 16 arranged with associated Weigh cells 17 cooperate, which in turn on the floor-standing stands 18 are supported.
- the aforementioned conveyor plate 32 now ensures that the in Arrow direction 43 falling material on the conveyor plate 32 this is rejected and in the inlet area of the lower Screw conveyor pair 12, 13 arrives.
- both lower screw conveyors 12, 13 convey over their entire length Length of the mix in the direction of the discharge opening 39, see above that there is an excellent discharge effect.
- the conveyor plate 32 ensures complete emptying of the container, because all material that is still in the area of End face 5 of the container 1 is from this Conveyor plate 32 detected and in the inlet area of the lower Screw conveyors 12, 13 promoted.
- This conveyor plate essentially consists of one approximately wing-shaped, triangular-shaped sheet, which is non-rotatable with the respective shaft of the lower screw conveyor 12, 13 is connected and the outer edge 44 approximately with the Outer edge 45 of the respective screw blade 26 is aligned and is the same with this.
- This conveyor plate also exists 32 from two slats 36, 37 arranged at an angle to one another, which in the axial direction and in the middle of the Auger shaft converge symmetrically and there one form radial end edge 34 over which these two lamellae 36,37 are connected.
- the conveyor plate 32 In the direction of the discharge side, the conveyor plate 32 is fixed with connected to the screw flange 33 and is accordingly non-rotatable connected to the shaft of the screw conveyors 12, 13.
- the yourself rotating screw flange 33 lies in the rest of the Drive flange 31 opposite, with the screw flange 33 is coupled. Both flanges 31, 33 are accordingly rotating driven and lie within the front edge 5 fixed to the housing according to FIGS. 7 and 8.
- the material is discharged by a Clearing device 41 facilitates, which consists of an angle plate exists, which is in the manner of the previously described Conveyor plate 32 but only a single lamella 36 or 37 while the other slat is missing. Otherwise it is given the same shape.
- This clearing device 41 ensures easier discharge of the material towards the Discharge opening 39.
- the discharge opening is from externally connected by a discharge slide 30, the is designed to be hydraulically raised and lowered and not with Flaps shown in detail interacts, which flaps over laterally arranged pivot bearing in front of the discharge opening Can be swiveled clockwise and counterclockwise are.
