- Fig. 1 shows a first embodiment of the stationary according to the invention
- Fig. 2 shows a second embodiment of the stationary waste crusher according to the invention.
- Fig. 3 shows a graph with load peaks and Lastdälern.
- Fig. 4 shows a third embodiment of the stationary according to the invention
- a first embodiment 100 of the stationary waste crusher 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 comminution 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 store 50 takes place via the power grid 10 up to the level of the designed power consumption, so that the energy thus stored is available for the further coverage of load peaks .
- 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.
- the starting current at the start of the electric motor 70 of this stationary crusher 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. Therefore, 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. As a result, 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 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.
- a second embodiment 200 of the stationary waste crusher according to the invention is shown.
- 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 may hardly be economically viable at the present 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. 4, a third embodiment 300 of the stationary waste crusher according to the invention is shown. This embodiment corresponds to that of Fig. 1, but instead of a crushing shaft in the first embodiment here two crushing shafts 80, 81 are provided (two-shaft shredder). The optional connection between the electric motor 70 and the crushing shafts 80, 81 via a transmission 90 (for example, a synchronous transmission).
- a transmission 90 for example, a synchronous transmission.
