- FIG. 1 A first embodiment 100 of the stationary waste chopping device according to the invention is shown.
- the stationary waste chopping device comprises at least at least one comminuting shaft 80, at least one electric motor 70 for driving at least one comminuting shaft 80, and a power supply connection 10 and energy store 50 for supplying the stationary waste comminuting device with electrical energy.
- the stationary waste chopping device is essentially characterized by an energy store 50 for storing energy and supplying the at least one electric motor 70 with electrical energy for partially covering the power peaks beyond the rated load of the mains connection 10, caused by the load peaks of the comminuting process.
- the crushing process takes place with strongly changing torques, and thus strongly changing power consumption of the electric motor 70.
- the graph clearly shows so-called load peaks and load valleys.
- the rated power of the system and thus the power grid connection 10, preferably in the middle between the expected load peaks and load valleys are designed.
- the power grid connection 10 in this design can not cover the load peaks that lie above the rated power of the power connection, additional energy must be supplied to the comminution system. This to cover this additional energy required, is through the energy storage 50 to Provided.
- the power from the power grid is preferably carried out in the size of the rated power of the interpretation.
- the additional power required to cover the rated current exceeding proportion of load peaks is thus applied by the energy storage 50 and provided by the electric motor 70 of the crushing shaft 80 as additional power to the power from the grid.
- the electrical energy store 50 is connected to the intermediate circuit 30 in the embodiment 100.
- the electrical energy store may be a capacitor in the form of a so-called SuperCAP, a battery or accumulator of very different design or system, or an electric flywheel storage or a similar electrical or mechanical energy store.
- a corresponding energy management module 40 is provided for the energy storage 50 for loading and unloading immediately before the energy storage or in the overall control.
- a combination of several identical, or several different energy storage is possible.
- the recharging of the energy accumulator 50 can also take place by means of a separately arranged internal combustion engine with attached generator, which also supplies its power via an AC / DC Transducer outputs in the intermediate circuit 30.
- the speed of the crushing shaft 80 via the electric motor 70 is also very easy to adjust the speed of the crushing shaft 80 via the electric motor 70 to the actual crushing task.
- Such an adjustment of the rotational speed may also be necessary in connection with the capacity of the energy accumulator 50. If the ratio of the load peaks, ie an increased energy demand from the energy storage 50, to the Lasttälern, ie the recharge of the energy storage 50 from the network, should not be sufficient to charge the energy storage 50 continuously, the speed of the motor 70 and so the crushing shaft 80th be adjusted so that the ratio of the load peaks to the load valleys is adjusted so that a continuous loading of the energy storage 50 is ensured, even if it is associated with a reduction in throughput.
- Another cause for the peak load of the power grid 10 is the starting current at the start of the electric motor 70 of this stationary crusher. This starting current is generally about four times the rated current. If this additional starting current must be obtained from the grid, the current connection must be made larger by this starting current exceeding the rated power.
- the invention is also based on the object over the rated current beyond starting current of the electric motor from the energy storage 50 and not to cover from the power grid 10.
- the grid connection and the upstream supply, switching and belay devices and cable connections need only be implemented in the size of the rated current of the electric motor, which means a significant cost savings both in the establishment of such a power connection and in the operation of the crusher itself.
- a complex control 90 with extensive software is provided in order to achieve the object underlying the invention.
- This control must take on the task that from the power grid 10 is never taken a higher power than the specified rated power, and that before the actual starting operation of the electric motor 70 sufficient capacity of the energy storage device 50 is available.
- the controller 90 After the starting process, the controller 90 must not release the actual comminution process until the energy store 50 has sufficient capacity again after the starting process.
- the controller 90 has the process control of the additional power supply from the energy storage 50 to the grid power 10 to the electric motor 70 to cover peak loads safely up to its maximum allowable power put.
- the controller 90 has to provide for the occurrence of so-called Lastdälern, for the charging of the energy storage device 50 from the difference of the power supply rated current 10 and the actual current consumption of the electric motor 70.
- the controller has 90 corresponding influence on the AC / DC converter 20, DC / AC converter 60 and to take the energy storage management 40, as far as one of these components is not already integrated in the controller 90, so that there is no overload or impermissible Discharge of the energy storage 50 comes.
- the energy storage device 50 of the stationary waste crusher 100 may consist, for example, of a battery or a rechargeable battery, wherein preferably lithium-ion cells are used.
- the embodiment 100 comprises an AC / DC converter 20 which converts the mains current, preferably 400 V AC, into a direct current of the intermediate circuit 30 with 200-800 V, preferably 650 V.
- an energy management module 40 Connected to this intermediate circuit is an energy management module 40, which controls the regulation the loading and unloading of the energy storage 50 takes over.
- the intermediate circuit 30 is also the DC / AC converter 60 or frequency converter, which provides the alternating current in the predetermined frequency of the electric motor 70 for driving the crushing shaft 80.
- FIG. 2 shows a second embodiment 200 of the stationary waste chopping device according to the invention.
- the energy store 50 is arranged such that it receives energy from an intermediate circuit 30 via the energy management 40 and releases it into it again.
- the capacity of this energy storage 50 will only be sized so large that only the load peaks, which is above the average between load peaks and load valleys, can be covered. The required capacity will tend to be relatively low.
- the second embodiment 200 provides the energy storage device 50, primarily designed as a battery or rechargeable battery, in the main line of the power supply of the motor 70.
- the battery is fed via the charger 25 continuously from the network 10 and loaded. Via a DC / AC converter 60, the power is returned to the motor 70, which drives the shaft 80.
- the engine 70 also receives the power required to cover the load peaks from the energy store or the battery 50. However, only the power is supplied to the energy store, which corresponds to the coverage of the required power of the middle between the load peaks and load valleys.
- FIG. 2 the same effect is achieved as with the embodiment 100, so that the network 10 is loaded only in the size that corresponds to the required power that corresponds to the average between the load peaks and load valleys.
- the capacity of the energy storage device 50 needs to be 200 according to FIG Fig. 2 be designed for the full power of the engine 70 or 75 including the load peaks.
- This embodiment according to FIG. 2 may not be economically feasible at current battery costs. However, experience and developments in the battery sector show that the cost will probably decrease by a factor of 10 in 5 years.
- a third embodiment 300 of the stationary waste crusher according to the invention is shown. This embodiment corresponds to that after Fig. 1 However, instead of a crushing shaft in the first embodiment here two crushing shafts 80, 81 are provided (two-shaft shredder).

Description
Die Erfindung betrifft eine stationäre Abfallzerkleinerungsvorrichtung mit wenigstens einer Zerkleinerungswelle, wenigstens einem Elektromotor zum Antreiben der wenigstens einen Zerkleinerungswelle und einem Stromnetzanschluss zur Versorgung der stationären Abfallzerkleinerungsvorrichtung mit elektrischer Energie.The invention relates to a stationary waste crusher with at least one shredding shaft, at least one electric motor for driving the at least one shredding shaft and a power supply connection for supplying the stationary waste shredding device with electrical energy.
In allen folgenden Beschreibungen, sowohl zum Stand der Technik wie auch der Beschreibung der Erfindung, werden zur Vereinfachung jeweils nur eine Komponente des Systems angeführt. Natürlich können jeweils zwei oder mehrere Komponenten im System vorhanden sein oder vorgesehen werden. So wird z.B. immer eine Zerkleinerungswelle oder ein Generator oder Elektromotor angeführt. Je nach Zerkleinerungssystem können es auch zwei oder mehr Zerkleinerungswellen sein. Auch hinsichtlich der Antriebskomponenten, können es z.B. auch mehrere Verbrennungsmotoren, Generatoren, Elektromotoren oder Energiespeicher und andere mehrfache Komponenten sein.In all of the following descriptions, both prior art and description of the invention, for simplicity, only one component of the system will be cited. Of course, two or more components may be present or provided in the system. For example, always listed a crushing shaft or a generator or electric motor. Depending on the size reduction system, it can also be two or more comminution waves. Also with regard to the drive components, e.g. also be multiple internal combustion engines, generators, electric motors or energy storage and other multiple components.
Vorrichtungen zur Abfallzerkleinerung, die für einen stationären Betrieb ausgelegt sind können beispielsweise einen Dieselmotor oder einen Elektromotor zum Antreiben einer Zerkleinerungswelle aufweisen. Eine derartige Vorrichtung zur Abfallzerkleinerung ist aus der
Im Falle einer elektrischen Antriebs der Zerkleinerungswelle ist ein Anschluss für ein Stromnetz vorgesehen. Die stationäre Abfallzerkleinerungsvorrichtung wird dann ausschließlich mit elektrischer Energie aus dem Stromnetz betrieben. Weil jedoch im Betrieb der Abfallzerkleinerungsvorrichtung Schwankungen im Bedarf an elektrischer Energie auftreten, z.B. weil festes und weiches Zerkleinerungsgut gemischt ist oder weil die aufzubringende Kraft zum Zerkleinern von der zufälligen Ausrichtung des Gutes an der Zerkleinerungswelle abhängt, können Lastspitzen auftreten, die teilweise deutlich über der Durchschnittslast liegen. Solche Lastspitzen sind durch den Elektromotor bzw. die dem Elektromotor aus dem Stromnetz zugeführte elektrische Energie/Leistung bereitzustellen.In the case of an electrical drive of the crushing shaft is provided a connection for a power grid. The stationary waste crusher is then operated exclusively with electrical energy from the mains. However, because fluctuations in the demand for electrical energy occur during operation of the waste crusher, for example because solid and soft comminuted material is mixed or because the force to be applied for comminuting the random orientation of the Good depends on the crushing shaft, peak loads can occur, which are sometimes significantly above the average load. Such load peaks are to be provided by the electric motor or the electrical power supplied to the electric motor from the power grid.
Ebenso wirkt sich der beim Start anfallende Anlaufstrom der bis zum Vierfachen des Nennstroms des Elektromotors betragen kann, auf die gesamten Energiekosten eines solchen Zerkleinerungssystems negativ aus.Likewise, the startup current at startup, which can be up to four times the nominal current of the electric motor, has a negative effect on the total energy costs of such a comminuting system.
Nach dem Stand der Technik wird versucht diesen negativen Aspekten durch sogenannte Schalteinrichtungen für den Sanftanlauf oder durch Frequenzumformer zu begegnen. Dies gelingt doch nur sehr unzureichend. Diese Schalteinrichtungen sind zudem bei den Netzbetreibern nicht sehr beliebt, da sie durch die Erzeugung von sogenannten Oberwellen zu einer "Verseuchung" des Netzes führen können.In the prior art, it is attempted to counteract these negative aspects by so-called switching devices for soft starting or by frequency converters. This succeeds only very inadequate. These switching devices are also not very popular with the network operators, since they can lead to a "contamination" of the network by the generation of so-called harmonics.
Dieses Vorgehen gemäß dem Stand der Technik ist dahingehend nachteilig, dass gegenüber den Stromnetzbetreibern kostenintensivere Tarife abgeschlossen werden müssen, welche nicht nur die mittlere sondern auch die maximale Leistungsentnahme bereitstellen. Dabei sind diese Tarife unabhängig davon, wie häufig die maximale Leistung entnommen wird. Es müssen also vergleichsweise hohe Kosten für Tarife mit hoher Leistung aufgewendet werden, auch wenn die maximale Leistung nur selten abgerufen wird.This procedure according to the prior art is disadvantageous in that more cost-intensive tariffs have to be concluded with regard to the power grid operators, which provide not only the average but also the maximum power take-off. These tariffs are independent of how often the maximum power is taken. Thus, it must be relatively high costs for tariffs with high power spent, even if the maximum power is rarely retrieved.
Nicht zu verkennen ist auch, dass es dabei nicht nur um die Kosten des sogenannten Arbeits- oder Leistungspreises geht. Vielfach stehen an bestimmten Standorten die Stromnetze in der Kapazität für die Antriebsleistung derartiger stationärer Zerkleinerer nicht zur Verfügung. Dazu kommt, dass die bereitgestellte Leistung nach dem größten Leistungsbedarf bemessen wird. Im Falle eines solchen Zerkleinerers also nach dem Anlaufstrom und der Spitzenlast des Zerkleinerungsprozesses. Für diesen sehr hohen Leistungsbedarf werden die einmaligen Kosten für den Netzanschluss und so für den überregionalen Netzausbau, und die fortlaufenden Kosten für die bereitgestellte Leistung bemessen. Dazu kommen neben den Kosten des sogenannten Arbeitspreises, auch die Kosten des sogenannten Leistungspreises, der sich überwiegend nach den höchsten 15 Minuten des Strombezugs eines Monats bemisst.It is also clear that this is not just about the cost of the so-called work or performance price. In many cases, the power grids in the capacity for the drive power of such stationary shredders are not available at certain locations. In addition, the provided power is measured according to the largest power requirement. In the case of such a shredder so after the starting current and the peak load of the crushing process. For this very high power requirement, the one-time costs for the grid connection and thus for the nationwide grid expansion, and the ongoing costs for the provided power are measured. In addition to the costs of the so-called labor price, there are also the costs of the so-called performance price, which is mostly measured after the highest 15 minutes of the electricity purchase of a month.
Neben diesen Kosten sind auch die zusätzlichen Kosten der sogenannten Hardware nicht unerheblich. Sowohl die Transformatoreneinrichtung, oder die Bereitstellung eines Dieselstromaggregates, wenn die Stromversorgung nicht aus dem Netz erfolgt, die Schalt- und Sicherungsanlagen, wie auch die Kabelverbindungen, müssen auf den maximal auftretenden Spitzenstrom ausgelegt werden, was erhebliche Kosten verursacht.In addition to these costs, the additional costs of the so-called hardware are not insignificant. Both the transformer device, or the provision of a diesel generator, when the power supply is not out of the network, the switching and safety systems, as well as the cable connections, must be designed for the maximum occurring peak current, which causes considerable costs.
Der Erfindung liegt daher die Aufgabe zugrunde, die genannten Nachteile zumindest teilweise zu überwinden, so die tatsächlich erforderlich Anschlussleistung des Stromnetzes erheblich zu reduzieren, und die auftretenden Leistungsspitzen durch den Anlaufstrom des Elektromotors und die Lastspitzen durch den Zerkleinerungsprozess selbst, zu vermeiden oder so weit als möglich abzumildern.The invention is therefore based on the object at least partially overcome the disadvantages mentioned, so to reduce the actually required power connection of the power grid considerably, and the power peaks occurring by the starting current of the electric motor and the load peaks through the crushing process itself, or so far as to avoid possible mitigate.
Diese Aufgabe wird gelöst durch eine stationäre Abfallzerkleinerungsvorrichtung gemäß Anspruch 1. Vorteilhafte Weiterbildung sind in den davon abhängigen Ansprüchen definiert.This object is achieved by a stationary waste crusher according to
Die erfindungsgemäße stationäre Abfallzerkleinerungsvorrichtung umfasst wenigstens eine Zerkleinerungswelle, wenigstens einen Elektromotor zum Antreiben der wenigstens einen Zerkleinerungswelle, einen Stromnetzanschluss zur Versorgung der stationären Abfallzerkleinerungsvorrichtung mit elektrischer Energie und einen Energiespeicher zum Speichern von Energie und zur wenigstens teilweisen Versorgung des wenigstens einen Elektromotors mit elektrischer Energie, insbesondere zur Abdeckung von Leistungsspitzen. Dies hat den Vorteil, dass der die Nennleistung übersteigende Anteil der Lastspitzen, nicht durch die Leistung aus dem Stromnetz abgedeckt werden muss, sondern vom Energiespeicher zur Verfügung gestellt wird. Solche Leistungsspitzen können auch beim Starten der Abfallzerkleinerungsvorrichtung in Form eines Anlaufstroms auftreten. Durch die Erfindung wird eine kleinere bereitgestellte Leistung des Stromnetzes ermöglicht, als wenn beispielsweise ein die Nennleistung übersteigende Anteil der Leistungsspitzen durch das Stromnetz bezogen werden müsste. Entsprechend wird auch ein schwaches Stromnetz weniger belastet, wodurch Ausfälle des Netzes vermieden werden können.The stationary waste chopping device according to the invention comprises at least one comminution shaft, at least one electric motor for driving the at least one comminution shaft, a power supply connection for supplying the stationary waste comminution device with electrical energy and an energy store for storing energy and at least partially supplying the at least one electric motor with electrical energy, in particular to cover power peaks. This has the advantage that the portion of the load peaks exceeding the rated power does not have to be covered by the power from the power grid, but is provided by the energy store.

Die hier in Folgenden beschriebenen Ausführungsformen sind nur beispielhaft für die Lösung der Aufgabenstellung. Andere Ausführungsformen zu Verfolgung der erfindungsgemäßen Ziele sind denkbar.The embodiments described below are only examples of the solution of the problem. Other embodiments for pursuing the objectives according to the invention are conceivable.
In
Die erfindungsgemäße stationäre Abfallzerkleinerungsvorrichtung umfasst zumindest wenigstens eine Zerkleinerungswelle 80, wenigstens einen Elektromotor 70 zum Antreiben zumindest einer Zerkleinerungswelle 80, und einen Stromnetzanschluss 10 und Energiespeicher 50, zur Versorgung der stationären Abfallzerkleinerungsvorrichtung mit elektrischer Energie.The stationary waste chopping device according to the invention comprises at least at least one
Die erfindungsgemäße stationäre Abfallzerkleinerungsvorrichtung ist wesentlich gekennzeichnet durch einen Energiespeicher 50 zum Speichern von Energie und zur Versorgung des wenigstens einen Elektromotors 70 mit elektrischer Energie zur teilweisen Abdeckung der über die Nennlast des Netzanschlusses 10 hinausgehenden Leistungsspitzen, hervorgerufen durch die Lastspitzen des Zerkleinerungsprozesses.The stationary waste chopping device according to the invention is essentially characterized by an
Wie aus der Grafik gemäß
Da der Stromnetzanschluss 10 bei dieser Auslegung, den über die Nennleistung des Stromanschlusses liegenden Lastspitzen nicht abdecken kann, muss dem Zerkleinerungssystem zusätzlich Energie zugeführt werden. Diese zur Abdeckung dieser zusätzlich erforderlichen Energie, wird durch den Energiespeicher 50 zur Verfügung gestellt. Der Strombezug aus dem Stromnetz erfolgt dabei bevorzugt in der Größe der Nennleistung der Auslegung.Since the
Die zusätzliche erforderliche Leistung zur Abdeckung des den Nennstrom übersteigenden Anteil der Lastspitzen wird also durch den Energiespeicher 50 aufgebracht und durch den Elektromotor 70 der Zerkleinerungswelle 80 als zusätzlich Leistung zum Leistungsbezug aus dem Stromnetz zur Verfügung gestellt.The additional power required to cover the rated current exceeding proportion of load peaks is thus applied by the
Da der die Nennleistung übersteigende Anteil der Lastspitzen, nicht durch die Leistung aus dem Stromnetz 10 abgedeckt werden muss, sondern vom Energiespeicher 50 zur Verfügung gestellt wird, ist eine kleinere bereitgestellte Leistung des Stromnetzes möglich, als wenn die den Nennstrom übersteigende Anteil der Lastspitzen durch das Stromnetz 10 bezogen werden müssten.Since the nominal power exceeding portion of the load peaks, must not be covered by the power from the
Der elektrische Energiespeicher 50 ist in der Ausführungsform 100 am Zwischenkreis 30 angeschlossen. Der elektrische Energiespeicher kann ein Kondensator in Form eines sogenannten SuperCAP sein, eine Batterie bzw. Akkumulator verschiedenster Bauart oder System, oder ein elektrischer Schwungradspeicher oder ein ähnlicher elektrischer oder mechanischer Energiespeicher sein. Dabei ist unmittelbar vor dem Energiespeicher oder in der Gesamtsteuerung, ein entsprechendes Energiemanagementmodul 40 für den Energiespeicher 50 für die Be- und Entladung vorgesehen.The
Auch eine Kombination aus mehreren gleichen, oder mehreren unterschiedlichen Energiespeichern ist möglich. So z.B. ein Batterieenergiespeicher für den Startvorgang und Abdeckung des den Nennstrom überschreitenden Anlaufstroms vom Elektromotor des Zerkleinerers 100 und ein Kondensator für die Abdeckung der kurzzeitigen Lastspitzen.A combination of several identical, or several different energy storage is possible. For example, a battery energy storage for the starting process and coverage of the nominal current exceeding starting current from the electric motor of the
Wenn sich wieder Lasttäler einstellen, wie sie aus der Grafik gemäß
Sollte sich im Betrieb eines solchen Zerkleinerungssystems zeigen, dass die sogenannten Lasttäler zum Wiederaufladen des Energiespeichers 50 aus dem Stromnetz nicht auseichen, kann das Wiederaufladen des Energiespeichers 50 auch durch einen gesondert angeordneten Verbrennungsmotor mit angebauten Generator erfolgen, der seine Leistung ebenfalls über einen AC/DC Wandler in den Zwischenkreis 30 abgibt.Should it become apparent during operation of such a comminution system that the so-called load valleys for recharging the
Mit der erfindungsgemäßen Ausbildung der Erfindung ist es auch sehr einfach möglich, die Drehzahl der Zerkleinerungswelle 80 über den Elektromotor 70 an die eigentliche Zerkleinerungsaufgabe anzupassen. Ein solches Anpassen der Drehzahl kann auch im Zusammenhang mit der Kapazität des Energiespeichers 50 erforderlich sein. Wenn das Verhältnis der Lastspitzen, also eines erhöhten Energiebedarfs aus dem Energiespeicher 50, zu den Lasttälern, also der Wiederaufladung des Energiespeichers 50 aus dem Netz, nicht ausreichen sollte, den Energiespeicher 50 kontinuierlich aufzuladen, kann die Drehzahl des Motors 70 und so der Zerkleinerungswelle 80 dahingehend angepasst werden, dass das Verhältnis der Lastspitzen zu den Lasttälern sich so einstellt, dass eine kontinuierliche Beladung des Energiespeichers 50 sicher gestellt ist, auch wenn damit eine Minderung der Durchsatzleistung verbunden ist.With the inventive design of the invention, it is also very easy to adjust the speed of the crushing
Diese hier beschriebenen stationären Zerkleinerer werden auch in bestimmten Zeitabständen, oder nach Eintreten bestimmter Ereignisse, auch im sogenannten Reversierbetrieb für sehr kurze Zeit betrieben, also in geänderter Drehrichtung des Motors 70 und der Zerkleinerungswelle 80. Ein solches Ereignis, das Anlass zu einer Änderung der Drehrichtung gibt, ist beispielsweise, dass sich das Aufgabegut vor der Zerkleinerungswelle so stark verdichtet aufgebaut hat, dass es zu keiner eigentlichen Zerkleinerung mehr kommt und so die Dursatzleistung stark vermindert wird.These stationary shredder described here are also operated at certain intervals, or after the occurrence of certain events, even in the so-called reversing for a very short time, so in a different direction of rotation of the
Um das zu beheben ist es erforderlich, die Drehrichtung der Zerkleinerungswelle 80 für eine kurze voreingestellte Zeit zu reversieren. Dadurch wird das Aufgabegut aufgelockert, und kann dann im anschließenden Normalbetrieb wieder mit ausreichender Durchsatzleistung zerkleinert werden.To remedy this, it is necessary to reverse the direction of rotation of the crushing
Um diesen Reversiervorgang einzuleiten, ist es jedoch erforderlich, zunächst einmal den Motor 70 mit der Zerkleinerungswelle 80 zum Stillstand zu bringen. Um den Zeitaufwand dafür so gering als möglich zu halten, wird dazu der Motor 70 vom Motorbetrieb auf Generatorbetrieb umgeschaltet. Im Generatorbetrieb kann die Bremsenergie bis zum Stillstand der Zerkleinerungswelle 80 zur Aufladung des Speichers 50 genutzt werden, und sollte dessen Aufnahmekapazität erschöpft sein, erfolgt eine Rückspeisung der Bremsenergie gegen Kostenerstattung ins Netz.To initiate this reversing, it is necessary, however, first to bring the
Eine weitere Ursache für die Spitzenbelastung des Stromnetzes 10 ist der Anlaufstrom beim Start des Elektromotors 70 dieses stationären Zerkleinerers. Dieser Anlaufstrom beträgt im Allgemeinden ungefähr das Vierfache des Nennstroms. Wenn dieser zusätzliche Anlaufstrom aus dem Netz bezogen werden muss, ist der Stromanschluss um diesen die Nennleistung übersteigenden Anlaufstrom größer auszulegen.Another cause for the peak load of the
Daher liegt der Erfindung auch die Aufgabe zugrunde, den über den Nennstrom hinausgehenden Anlaufstrom des Elektromotors aus dem Energiespeicher 50 und nicht aus dem Stromnetz 10 zu decken. Dadurch braucht der Netzanschluss und die vorgelagerten Versorgungs-, Schalt- und Sicherungsgeräte und Kabelverbindungen, nur in der Größe des Nennstroms des Elektromotors ausgeführt zu werden, was eine erhebliche Kosteneinsparung sowohl bei der Errichtung eines solchen Stromanschlusses und auch im Betrieb des Zerkleinerers selbst bedeutet.Therefore, the invention is also based on the object over the rated current beyond starting current of the electric motor from the
Zur Steuerung der erfindungsgemäßen Zerkleinerungsvorrichtung 100 ist eine komplexe Steuerung 90 mit umfangreicher Software vorgesehen, um die der Erfindung zu Grunde liegende Aufgabe zu lösen. Diese Steuerung muss die Aufgabe übernehmen, dass aus dem Stromnetz 10 nie eine höhere Leistung als die festgelegte Nennleistung entnommen wird, und dass vor dem eigentlichen Startvorgang des Elektromotors 70 ausreichende Kapazität des Energiespeichers 50 zur Verfügung steht. Nach dem Startvorgang darf die Steuerung 90 den eigentlichen Zerkleinerungsprozess erst frei geben, wenn der Energiespeicher 50 nach dem Startvorgang wieder über ausreichende Kapazität verfügt. Im Zerkleinerungsprozess selbst hat die Steuerung 90 die Prozessregelung der zusätzlichen Energiezufuhr aus dem Energiespeicher 50 zu der Netzleistung 10 an den Elektromotor 70 zur Abdeckung von Lastspitzen bis zu dessen zulässiger maximalen Leistung sicher zu stellen. Umgekehrt hat die Steuerung 90 beim Auftreten von sogenannten Lasttälern, für die Aufladung des Energiespeichers 50 aus der Differenz der Stromnetznennleistung 10 und der tatsächlichen Stromaufnahme des Elektromotors 70 zu sorgen. Dabei hat die Steuerung 90 entsprechenden Einfluss auf den AC/DC Wandler 20, DC/AC Wandler 60 und auf das Energiespeicher Management 40 zu nehmen, soweit eine dieser Komponenten nicht bereits in der Steuerung 90 integriert ist, so dass es zu keiner Überladung oder unzulässigen Entladung des Energiespeichers 50 kommt.To control the
Der Energiespeicher 50 der stationären Abfallzerkleinerungsvorrichtung 100 kann beispielsweise aus einer Batterie oder einem Akkumulator bestehen, wobei vorzugsweis Lithium-Ionen Zellen Verwendung finden. Weiterhin umfasst die Ausführungsform 100 einen AC/DC Wandler 20, der den Netzstrom, vorzugsweise 400 V Wechselstrom, in einen Gleichstrom des Zwischenkreises 30 mit 200 - 800 V umwandelt, vorzugsweise 650 V. An diesen Zwischenkreis ist ein Energiemanagementmodul 40 angeschlossen, welches die Regelung der Be- und Entladung des Energiespeichers 50 übernimmt. Am Zwischenkreis 30 ist auch der DC/AC Wandler 60 oder Frequenzumformer, der den Wechselstrom in der vorgegebenen Frequenz dem Elektromotor 70 zum Antrieb der Zerkleinerungswelle 80 zur Verfügung stellt.The
In
Bei der ersten Ausführungsform 100 ist der Energiespeicher 50 so angeordnet, dass er über das Energiemanagement 40 Energie aus einem Zwischenkreis 30 aufnimmt und in diesen wieder abgibt. Die Kapazität dieses Energiespeichers 50 wird nur so groß bemessen sein, dass nur die Lastspitzen, die über dem Mittel zwischen Lastspitzen und Lasttälern liegt, abgedeckt werden kann. Die erforderliche Kapazität wird eher relativ gering sein.In the
Die zweite Ausführungsform 200 sieht den Energiespeicher 50, vorrangig als Batterie bzw. Akkumulator ausgeführt, im Hauptstrang der Energieversorgung des Motors 70 vor. Die Batterie wird über das Ladegerät 25 kontinuierlich vom Netz 10 gespeist und geladen. Über einen DC/AC Wandler 60 wird die Leistung wieder an den Motor 70 abgegeben, der die Welle 80 antreibt.The
Dabei bekommt der Motor 70 auch die zur Abdeckung der Lastspitzen erforderliche Leistung aus dem Energiespeicher bzw. der Batterie 50. Dem Energiespeicher wird jedoch nur jene Leistung zugeführt, die zur Abdeckung der erforderlichen Leistung die der Mitte zwischen den Lastspitzen und Lasttälern entspricht.The
Bei den sogenannten Lasttälern, wo der Energiebedarf des Motors 70 unterhalb der oben beschriebenen Mitte zwischen Lastspitzen und Lasttälern liegt, kann der Energiespeicher bzw. die Batterie 50, wieder um die vorher zur Abdeckung der Lastspitzen entnommenen Energie, aufgeladen werden.In the so-called last valleys, where the energy requirement of the

Die zusätzliche zur Abdeckung der Lastspitzen erforderliche Energie, und die Leistung zur Aufbringung des Anlaufstroms des Motors 70 bzw. 75, deckt der Energiespeicher bzw. die Batterie 50 ab. Daher muss die Kapazität des Energiespeichers 50 in der zweiten Ausführungsform 200 gemäß
