Definitions

  • the invention relates to a coarse dirt trap device for lifting the coarse material out of a pulper and a corresponding working method.
  • Pulper also called pulper
  • Pulper are used for processing used by mixtures of substances, the easily friable constituents include.
  • An important area of application lies in the treatment of waste and waste-like Substances.
  • Such a pulper usually has a container which is equipped with a rotor. In operation it will mixture of substances to be prepared together with a liquid, generally water, poured into the container. The rotor is set in rotation and thereby generates strong flow forces. These flow forces ensure that the solids contained in the pulper are easily friable are frayed. In addition to the defibration sometimes a shortening of fibers takes place some of the friable materials and others in the mixture contained substances in solution. After the heavyweight of the process, however, consists in defibration here only spoken of "defibrillation” or “defibrillation” and the comminution and disintegration taking place next to it not mentioned separately.
  • the frayed components of the introduced mixture of substances form a suspension together with the liquid, which, for example, are drawn out of the pulper using a perforated screen can be.
  • Coarse dirt traps are used to remove such coarse matter from the pulper common. These generally point Tine up. They dive into the pulper in which the coarse substances are in a liquid. It can this liquid is either the suspension, or it may also be advantageous to start the suspension first from the pulper, and only then the remaining ones in the pulper Remove coarse matter, again one Liquid, preferably process water, filled into the pulper becomes. The coarse substances floating in the liquid get caught in the coarse dirt trap and then become over an extension of the coarse dirt trap removed from the pulper.
  • a coarse dirt trap is known from DE 32 25 026 C2, which has a pedestal that is at least 90 degrees is rotatable.
  • a support arm can be removed and stored on this column stored with a grass catcher at the bottom Has tines. The is used to collect the coarse material Support arm with the grass catcher on the pedestal vertically in the Pulper shut down so that the grass catcher is in the liquid immerse and can flow through it.
  • Catch the coarse substances floating in the liquid itself in the prongs of the grass catcher, which is then removed the coarse material is again perpendicular to the support arm from the pulper is brought out. Swings to throw off the coarse material the support arm in its upper position around the column in an area outside the pulper.
  • the grass catcher then hits a catch stop on what a Tilting the basket and thus throwing off the coarse material causes a ready container.
  • Another coarse dirt collector is from EP 0 598 187 B1 known.
  • the coarse dirt trap is located in a trough connected to the interior of the pulper is.
  • the coarse dirt collector is swiveled out of the trough around a horizontal axis in the interior of the Pulpers retracted and after the coarse dirt through the Tines were caught, swung out of the pulper again.
  • the swivel angle is dimensioned such that the coarse dirt trap with the coarse substances adhering to it can be swung out so far that it is above the Upper edge of the trough is located. Be in the final phase the coarse materials with a special scraper from stripped the coarse dirt trap.
  • Coarse dirt trap only to discharge those coarse substances which because of their lower specific weight or their larger surface area is floating in the liquid (hereinafter also referred to simply as "light coarse material"), because in the light coarse substances other substance groups are more concentrated than in the heavy coarse materials and by separating the two groups, better opportunities for exploitation or adapted disposal options become.
  • the heavy coarse matter is therefore usually discharged through a heavy material lock.
  • the present invention is based on the object Simplify the mechanics of the coarse dirt collector and thus the mechanical and control engineering effort to a minimum and also the cycle time too shorten.
  • the coarse dirt collector should have a large capacity have to collect the coarse material and also the Possibility of selective discharge of the light Offer coarse materials.
  • the invention is also intended to be a corresponding one Provide working procedures.
  • a coarse dirt trap is used which also pivoted into the pulper by rotation about an axis becomes.
  • this circular movement takes place not a horizontal one, but a horizontal one inclined axis.
  • the pulper axis is not aligned vertically, this is how the swivel movement takes place accordingly not in an inclination to the horizontal, but is inclined to the plane that is on the pulper axis is vertical.
  • This causes those on the grass catcher Tines when swiveling into the pulper in the end position in a horizontal at least, but rather in one come slightly upwards. In this position can the coarse substances floating in the liquid ideally be caught.
  • they swing out they come Tines in the end position in a downward inclined vertical Position in which the coarse material automatically - without further external influences, e.g. the use of a scraper, - fall into a container, which is here to catch is ready.
  • the coarse dirt trap according to the invention or the corresponding one Working methods point towards the known approaches the advantage of being only one movement must execute about said inclined axis of rotation.
  • the mechanical and control engineering effort is compared minimized the state of the art and the cycle time shortened.
  • a trough in which the coarse dirt trap moves is unnecessary.
  • Such a trough is required if - As is the case in EP 0 598 187 B1 - the tines that are on the The coarse debris catcher is located during the phase catching and also during most of the swing-out movement have a downward inclined position. Here you can expect during the rotation that the trapped coarse material falls off the tines unintentionally, if not through the wall of the trough, on which moving the tines along, an obstacle is created.
  • the trough is an additional component that the Wear is subject to change and its replacement costs.
  • a shut-off device is also necessary in the trough, which must be closed during the defibration process, to prevent friable material in the trough caught without being frayed, which is undesirable is.
  • 1 and 2 show the coarse dirt trap on the one hand in the suitable end position for collecting the coarse material in the pulper or on the other hand in the disposal of these coarse materials suitable end position.
  • the entire coarse dirt trap is designed so that a maximum collecting capacity is reached. Because of the least horizontal, more inclined position the tine in the catch position also becomes selective Removal of the light coarse material enables such a greater sieving effect is generated and the tines themselves higher up in the suspension.
  • a preferred application for the coarse dirt trap described is the treatment of waste for one biological recycling of individual components. In doing so the biologically usable components from the non-biologically usable components separately. Because the biological recyclable components are easily shredded compared to the other ingredients that are difficult or cannot be shredded. The generated and by that Sieve separated suspension in which the biologically usable Components are then concentrated biological recycling are fed while the biological non-recoverable components after the deduction of the suspension remain in the pulper, i.e. the coarse materials be sent to another appropriate form of utilization can.
  • the waste mixture AF is filled into the pulper 1, the Axis P is vertical in the illustration. It will water W also added.
  • the waste water mixture is set in motion. It a strong toroidal flow is generated, which in addition leads to the biologically usable components of the waste mixture be frayed.
  • These fibers form with the liquid present in the pulper is a suspension which through the perforated screen located in the lower part of the pulp 3 is subtracted. What remains are those that cannot be used biologically Components of the waste caused by the flow forces remain largely undamaged, i.e. the Coarse materials.
  • the pulper is provided with a lid 4 to close it to ensure against odor emissions.
  • This Cover 4 has an opening for the discharge of the coarse material the coarse dirt catcher, to which an odor-tight seal is attached Hood 5 for the coarse dirt trap connects. Is possible also to design the pulper cover so that it overall is opened when the coarse material is discharged.
  • the pulper becomes again after the suspension S has been drawn off filled with a liquid, preferably with water W.
  • the heavy coarse matter sinks down and can from there, e.g. can be removed via a heavy material lock 6.
  • the light coarse substances because of their nature float in the liquid through a coarse dirt trap 7 removed.
  • This coarse dirt collector 7 consists of a support arm 8 and a collecting basket 9.
  • the support arm is on the pulper itself suspended from a suspension 10 or has one from the pulper independent support structure. He is on one Shaft rotatably mounted. The swivel range is between 90 ° and 270 °.
  • the catcher 9 is attached to the support arm 8. This consists of a frame 11 in which there is a grate from fixed or variable lattice or parallel arranged Rods or bars. Perpendicular to the frame or slightly inclined upwards, tines Z are attached.
  • the shape of the support arm is like this designed (curved and / or angled) that the opening, provided in the pulper cover for throwing off the coarse dirt is as small as possible.
  • the Frame is attached to the support arm 8 so that it does this task with a maximum computing area. additionally the positioning of the frame on the support arm is aligned so that he has an optimal catch position, further in its movement to or from the drop position between the container wall of the pulper and the rotor come through well and the coarse dirt does not fall off too early.
  • the carrier arm of the Coarse dirt collector now, for example, a rotary movement of at least 90 ° and at most 270 °, preferably between 150 ° and 200 °, off.
  • This rotary movement is one Axis A outside the pulper at the upper edge of the cylinder part, which is inclined to the horizontal, preferably by 20 ° to 40 °.
  • This rotation movement dives the grass collector completely into the liquid.
  • the frame fills the area between the rotor and the outer wall of the pulper as optimally as possible and located preferably in a slightly vertical and also inclined to the radial to the pulper axis.
  • the tines attached to the frame point slightly upwards. This position ensures that a possible large part of the coarse substances floating in the liquid caught in the flow through the grass catcher.
  • the grass catcher is then turned in the opposite direction the support arm lifted out of the pulper. Move it the tines initially by rotating the support arm into the horizontal and with increasing rotation Crossing the pulper edge downwards, so that the coarse dirt automatically through the opening in the pulper cover and is thrown off through the hood for the coarse dirt trap.
  • the dropping can be supported mechanically in that the dirt trap moves against a stop and / or it is suddenly moved back suddenly.
  • the dropping takes place in a discharge hopper 13, which the coarse material in the Entrance to a drainage system or a conveyor passes.
  • the Pulper system, hood for the Coarse dirt trap, collecting funnel and downstream aggregate can be encapsulated odor-tight to connect to an exhaust system to be connected.
  • the coarse dirt collector has an electrical or hydraulic one Drive on.
  • the control of the coarse dirt collector can be partially or completely automated.
  • the suspension generated and separated by the sieve in which the biologically usable constituents are concentrated biological recycling (fermentation, Composting).
  • the heavy coarse matter contain largely inert materials (stones, ceramics, Glass, metals, bones) that are otherwise recycled or deposited can be.
  • Those separated with the coarse dirt trap light coarse materials are particularly exposed Plastics, textiles and wood together. Because of the concentration of plastics in this fraction, is theirs Recovery possible. Otherwise the are in the light coarse materials predominantly present very high calorific value Materials good for combustion. It is also a further processing of the light coarse materials before their Recycling or their disposal possible. It can a drainage and / or crushing and / or Act sorting. It is also a drying and / or one biological after-treatment conceivable.
  • the container shape and the shape of the frame and the tines can be chosen arbitrarily.
