Description
Die Erfindung betrifft ein Verfahren zum Betreiben des Luftkreislaufes und Fördern des Gutstromes im Gehäuse eines Hammerbrechers, der vorzugsweise Altmaterial zerkleinert. Die Erfindung betrifft ferner ein Gehäuse des Hammerbrechers zur Durchführung des Verfahrens.The invention relates to a method for operating the air circuit and conveying the material flow in the housing of a hammer crusher, which is preferably old material crushed. The invention further relates to a housing of the hammer crusher Execution of the procedure.
Es ist allgemein bekannt, daß Hammerbrecher zum Zerkleinern von Schrott, wie Autokarosserien, von sogenannter weißer Ware sowie Elektronikschrott und dgl. verwendet werden.It is well known that hammer crushers for crushing scrap, such as Car bodies, of so-called white goods as well as electronic waste and the like. be used.
Derartige Hammerbrecher bestehen im wesentlichen aus einem Gehäuse mit einem Guteinlaß, einem oberen und unteren Klassierrost, einem im Gehäuse drehbar gelagerten Rotor mit Werkzeugen wie Hämmern, der mit relativ hoher Umfangsgeschwindigkeit angetrieben wird. Der im Gehäuse umlaufende Rotor verleiht dem Hammerbrecher dadurch praktisch unerwünschte Eigenschaften eines Radialgebläses. Dabei wirken die Hämmer als Schaufeln, die die Umgebungsluft durch einen Teil der Rostöffnungen des unteren Klassierrostes ansaugen und durch die Rostöffnungen des oberen Klassierrostes ausblasen. Such hammer breakers essentially consist of a housing with a Good inlet, an upper and lower classification grate, one rotatable in the housing mounted rotor with tools like hammers, the one with relatively high Peripheral speed is driven. The rotor rotating in the housing gives the hammer crusher practically undesirable properties Radial fan. The hammers act as blades that carry the ambient air suck through part of the grate openings of the lower grate and through Blow out the grate openings of the upper grate.
Im Gehäuseinneren wird durch diesen Effekt ein Überdruck gebildet, der sich gegenüber dem Atmosphärendruck auszugleichen versucht. Dadurch kommt es in der Umgebung des Hammerbrechers je nach der Beschaffenheit des zu zerkleinernden Gutes zu erheblichen Staubentwicklungen bzw. Umweltbelastungen.This effect creates an overpressure inside the housing, which tries to compensate for atmospheric pressure. It comes in the environment of the hammer crusher depending on the nature of the material to be crushed Good for considerable dust or environmental pollution.
Gemäß der DE 32 33 985 A1 wurde schon für mit Entstaubungsanlagen verbundene Hammerbrecher festgestellt, daß die Größe und Luftleistung der Entstaubungsanlage vielmehr von der Gebläsewirkung des Hammerrotors beeinflußt wird als von der eigentlich abzusaugenden Staubmenge.According to DE 32 33 985 A1 was already associated with dedusting systems Hammer breakers found that the size and air performance of the dedusting system rather is influenced by the fan action of the hammer rotor than the amount of dust actually to be extracted.
Um die überdimensionierten Entstaubungsanlagen, die einen hohen Energieverbrauch
erfordern und dazu noch sehr lärmintensiv und bauaufwendig sind, zu
optimieren, wurde deshalb nach der DE 32 33 985 A1 vorgeschlagen, die
nachteilige Gebläsewirkung des Hammerrotors durch eine Unterteilung des
Gehäuses in mindestens zwei in Rotordrehrichtung hintereinander liegende Räume
zu reduzieren.
Wenn dies auch eine wirksame Lösung schien, blieb der praktische Erfolg aus, da
erkannt wurde, daß sich prinzipiell die beschriebene Gebläsewirkung nicht
ausschalten läßt und es im großen und ganzen bei den kostenaufwendigen und
umweltbelastenden überdimensionierten Entstaubungsanlagen blieb. In order to optimize the oversized dedusting systems, which require high energy consumption and are also very noise-intensive and construction-intensive, it was proposed according to DE 32 33 985 A1 to reduce the disadvantageous blower effect of the hammer rotor by dividing the housing into at least two rotor rotations one after the other Reduce spaces.
Although this appeared to be an effective solution, practical success failed to materialize, since it was recognized that, in principle, the blower effect described cannot be switched off and, on the whole, it remained with the costly and polluting oversized dedusting systems.
Gemäß der DE 35 17 579 C2 wird zwar die Möglichkeit eröffnet, mit geschlossenem oder geöffnetem Rost den Hammerbrecher zu betreiben, jedoch bietet diese Lehre keinen Ansatz, das eingangs dargestellte Problem zu lösen.According to DE 35 17 579 C2, the possibility is opened with a closed one or open grate to operate the hammer crusher, however, this teaching offers no approach to solve the problem described at the beginning.
Auch der in Fig. 1 in der DE 37 44 241 C2 dargestellte Vorschlag eines
Hammerbrechers mit Absaugung zeigt schon im Ansatz deutlich, daß die dortigen
Druckverhältnisse und -zusammenhänge das aufgezeigte Problem nicht lösen
können.
Weitere Untersuchungen, so z.B. aus der US 3,004,721 Lösungsansätze für die
Beseitigung der dem einschlägigen Stand der Technik anhaftenden Mängel zu
finden, blieben ohne Erfolg.The proposal of a hammer breaker with suction shown in DE 37 44 241 C2 in FIG. 1 clearly shows even in the beginning that the pressure conditions and relationships there cannot solve the problem shown.
Further investigations, for example from US 3,004,721 to find solutions for eliminating the deficiencies inherent in the relevant prior art, were unsuccessful.
Nach der erfindungsgemäßen Aufgabe soll deshalb die an sich nachteilige Gebläsewirkung für den Betrieb des Hammerbrechers genutzt, das Gehäuse entsprechend gestaltet und der Aufwand für erforderliche Entstaubungsanlagen und Energie gesenkt werden.According to the object of the invention, therefore, the blower effect, which is disadvantageous per se used for the operation of the hammer crusher, the housing accordingly designed and the effort for required dedusting systems and energy be lowered.
Dabei soll das Verfahren zum Betreiben des Luftkreislaufes und Fördern des Gutstromes im Gehäuse eines Hammerbrechers während des Zerkleinerns von Altmaterial mit den Verfahrensschritten
- kontinuierliche Aufgabe des zu zerkleinernden Altmaterials über einen Guteinlaß im Gehäuse,
- Zerkleinern des Altmaterials mittels eines im Gehäuse drehend gelagerten, mit Werkzeugen bestückten und eine Ventilatorwirkung erzeugenden Rotors,
- Förderung des Gutstromes des zerkleinerten Altmaterials durch einen im oberen Gehäuse vorgesehenen Gutaustritt mit oberem Klassierrost sowie Förderung des Gutstromes des zerkleinerten Altmaterials durch einen im unteren Gehäuse vorgesehenen Gutaustritt mit unterem Klassierrost innerhalb eines internen Luftkreislaufes
- continuous feeding of the old material to be shredded through a good inlet in the housing,
- Shredding of the old material by means of a rotor mounted in the housing in a rotating manner, equipped with tools and producing a fan effect,
- Promotion of the good flow of the shredded old material through a good outlet provided in the upper housing with upper classifying grate and promotion of the good flow of the shredded old material through a good outlet provided in the lower housing with lower classifying grate within an internal air circuit
Für den Fall des Anschlusses einer Entstaubungsanlage kann diese nun in ihrer zu erzeugenden Luftleistung um den Anteil der schon zirkulierenden Umluft reduziert werden.In the event that a dedusting system is connected, it can now be closed generating air output is reduced by the proportion of circulating air that is already circulating become.
Vorteilhaft wird so auch durch die Verlegung des Anschlusses der Entstaubungsluft zum Ende des Kanals bzw. in den Bereich des unteren Klassierrostes eine bessere Sichtwirkung zur Reinigung des zerkleinerten Schwergutes, wie z.B. zerkleinerte Metallteile, aus dem Hammerbrecher über den Guteinlaß zugeführten Alt-Autokarosserien von dem zerkleinerten Leichtgut, wie z.B. Polstermaterialien (Shredderleichffraktion), erreicht.It is also advantageous if the connection of the dedusting air is laid a better one at the end of the channel or in the area of the lower grating Visibility for cleaning the shredded heavy goods, e.g. crushed Metal parts, from the hammer crusher through old car bodies fed through the inlet from the shredded light goods, e.g. upholstery materials (Shredder light fraction).
Diese Sichtwirkung kann noch dadurch verstärkt werden, wenn die unter dem Bereich des unteren Klassierrostes vorgesehene Einrichtung zur weiteren Verarbeitung, Sortierung und/oder Förderung des zerkleinerten Altmaterials eine Stufe/Kaskade erhält, in welcher ein zusätzlicher Ventilator mit geringer Leistung Luft einbläst, womit die leichteren Bestandteile, wie z.B. die sogenannte Shredderleichtfraktion, noch sauberer von der Metallfraktion getrennt dem Entstaubungsschacht zugeführt werden.This visual effect can be enhanced if the under the Area of the lower grating for further processing, Sorting and / or conveying the shredded waste material Stage / cascade, in which an additional fan with low power air with which the lighter components, e.g. the so-called shredder light fraction, separated even more cleanly from the metal fraction of the dedusting shaft be fed.
Ein zusätzlicher Effekt ist erreichbar, wenn mit der Zugabe von feinverdüstem oder vernebelten Wasser während des Zerkleinerungsprozesses in den Umluftstrom bzw. in das Gehäuse mittels der Wassermoleküle bzw. der großen Oberfläche der Wasserteilchen dem aufgegebenen Altmaterial, wie z.B. Autokarosserien, bei der Zerkleinerung eine erhebliche Menge von Wärme entzogen wird. Dadurch kann die Gefahr von Verpuffungen und Bränden bzw. die Entstehung von verbrannten Kohlenwasserstoffen oder sogenanntem "blauen Rauch", wie häufig durch die im Altmaterial vorhandenen Treibstoffreste oder auch Ziehölreste verursacht, verringert werden.An additional effect can be achieved if with the addition of finely atomized or nebulized water into the circulating air flow during the shredding process or into the housing by means of the water molecules or the large surface of the Water particles in the abandoned waste material, e.g. Car bodies at which Shredding a significant amount of heat is extracted. This allows the Risk of deflagration and fire or the occurrence of burned Hydrocarbons or so-called "blue smoke", as often caused by the im Old material causes existing fuel residues or pull oil residues, reduced become.
Die Eindüsung des Wassernebels erfolgt zweckmäßigerweise durch Rohrleitungen in das Gehäuse oberhalb des Rotors. Die Wassernebelmenge pro Zeiteinheit kann einerseits in Abhängigkeit von der Materialmenge im Zerkleinerungsraum durch Messung der Stromaufnahme des Antriebsmotors für den Rotor und andererseits durch Messung der Temperaturdifferenz der Umluft im Vergleich zur Umgebungsluft reguliert zugeführt werden.The water mist is expediently injected through pipes in the housing above the rotor. The amount of water mist per unit of time can on the one hand depending on the amount of material in the shredding room Measurement of the current consumption of the drive motor for the rotor and on the other by measuring the temperature difference of the circulating air compared to the ambient air be fed regulated.
Im einzelnen ist die weitere verfahrensmäßige Ausbildung den Ansprüchen 2 bis 10
zu entnehmen.In particular, the further procedural training is
Der verfahrensgemäßen Aufgabe zugeordnet soll ein Gehäuse eines Hammerbrechers, bestehend aus einem in einem Gehäuse drehend gelagerten, mit Werkzeugen bestückten Rotor, einem Guteinlaß, einem im oberen Gehäuse vorgesehenen Gutaustritt mit oberem Klassierrost und einem im unteren Gehäuse vorgesehenen Gutaustritt mit unterem Klassierrost, verwendet werden, bei dem erfindungsgemäß das Gehäuse eine Umlenkhaube nach dem oberen Klassierrost aufweist, dem sich ein Kanal anschließt, der zum Bereich des unteren Klassierrostes führt. A housing of a should be assigned to the procedural task Hammer crusher, consisting of a rotating in a housing, with Tools equipped rotor, a good inlet, one in the upper housing provided good exit with upper grating and one in the lower housing provided good exit with lower grating, can be used in the According to the invention, the housing has a deflection hood according to the upper grating has a channel that leads to the area of the lower grating leads.

mit einem Guteinlaß 3, einem Gutaustritt mit oberem Klassierrost 4, einem
Gutaustritt mit unterem Klassierrost 5 sowie einem im Gehäuse 1 drehend

wie z.B. Amboß an dem oberen Klassierrost 4 (Fig. 1), das in einen

Wie eingangs schon beschrieben, herrschte bisher die Auffassung, die
Gebläsewirkung des Rotors 2 durch eine Unterteilung des Gehäuses 1 und
Absaugung der Entstaubungsluft an den jeweiligen Klassierrosten 4, 5 ausschalten

Blower effect of the
Die Erfindung macht sich nun die zuvor ungewünschte Gebläsewirkung
überraschend insofern zu nutze, indem der Luftstrom als Umluft wirksam eingesetzt
wird und der Luftstrom zusammen mit dem den oberen Klassierrost 4 passierenden,
klassierten Gutstrom des zerkleinerten Altmaterials durch eine bisher nicht übliche
Umlenkhaube 8 umgelenkt und vertikal nach unten in einem vom Gehäuse 1
abgegrenzten Kanal 6 geführt, dieser Gutstrom im Bereich des unteren
Klassierrostes 5 mit dem hier klassierten Gutstrom des zerkleinerten Altmaterials

geführt sowie andererseits der vereinigte Gutstrom des zerkleinerten Altmaterials zu
einer Einrichtung 11 für die weitere Verarbeitung, Sortierung und/oder Förderung
desselben geführt wird.The invention now makes the previously undesired fan action

In besonderen Fällen ist es erforderlich, dem Gehäuse 1 gemäß Fig. 2 eine
Entstaubungsanlage zuzuschalten, insbesondere dann, wenn im Gehäuse 1
Überdruck vorherrscht und/oder eine wirksamere Trennung der sogenannten Shredderleichtfraktion
von der Schwerfraktion (Fe) erfolgen muß. Hierzu wird nun energetisch
günstig und bauaufwandsenkend eine um den Anteil der infolge der Gebläsewirkung
