Definitions

the invention relates to a device for comminuting piece goods with a drive motor, which is coupled in a force-transmitting manner to at least one hydraulic pump of a hydrostatic drive, the hydrostatic drive having at least one hydraulic motor, which has a first feed line and a first return line for hydraulic oil with the at least one hydraulic pump is connected, and the at least one hydraulic motor is coupled in a force-transmitting manner to a transmission which is coupled in a force-transmitting manner to a comminution rotor on which tools for comminuting the piece goods are arranged, in a first bypass line which is arranged between the first feed line and the first return line , a short-circuit valve unit is arranged, and in a further bypass line, which is arranged between the first feed line and the second return line, an outlet valve unit is arranged, which has a second Return line is connected to the at least one hydraulic motor.
Such a device is for example from the WO 2002/000349 A1 known.
the hydrostatic drive is intended to avoid the hard starting behavior of a mechanical drive that places a heavy load on the power transmission elements and brings about an uncontrolled following behavior.
the drive motor arrangement is connected to the rotor arrangement via a rotational direction change gear.
the direction of rotation change gearbox is controlled, for example, by monitoring the supply current drawn by the drive motor arrangement.
a device for crushing piece goods is from the EP 2 789 391A1 known.
the operating phase of the start-up comprises a period of time from the start of the drive motor until a defined target speed of the comminution rotor is reached.
the shredding rotor is driven at the defined target speed or in a defined target speed range, so that piece goods can be shredded by means of the shredding rotor.
the operating phase of the shutdown which typically follows the operating phase of the shredding, the device is stopped in a controlled manner in order to bring the shredding rotor to a standstill.
the comminuting rotor Since the comminuting rotor has a very high mass, the comminuting rotor is very sluggish compared to a rotation about its own axis when starting. If the comminution rotor was driven directly via the drive motor and without an interposed hydrostatic drive, this high moment of inertia would have to be overcome by the drive motor alone. The drive motor would have to be appropriately large for this relatively short operating phase of starting. With the hydrostatic drive arranged between the drive motor and comminution rotor, on the other hand, the high moment of inertia is advantageously overcome by continuously increasing the delivery volume of hydraulic oil of the at least one hydraulic pump when starting, so that the speed of the at least one hydraulic motor also increases continuously. The drive motor coupled to the at least one hydraulic pump therefore does not have to be dimensioned for this comparatively short operating phase of starting, but can be adapted to the needs of the operating phase of shredding and does not need to be overstressed when starting.
the hydrostatic drive also has advantages in the operating phase of the shutdown, since the flow rate of hydraulic oil of the at least one hydraulic pump can be continuously reduced in order to brake the once accelerated mass of the comminution rotor during shutdown.
the resulting pressure increase in the first supply line and the first return line of the hydrostatic drive can be reduced using optional pressure relief valves.
the drive motor also brakes the comminution rotor.
the advantages achieved by arranging the hydrostatic drive in the device for shredding piece goods during the operating phases of starting and shutting down the shredding device are accompanied by a difficulty in a fourth operating phase, which, however, only occurs in the event of a malfunction in operation.
the operating phase of the emergency operation which is activated by an emergency safety function, which triggers a shutdown of the supply of the device with current from a current source.
the emergency safety function can be activated automatically, for example, by manually actuating an emergency switch arranged on the device or by a control device.
the emergency safety function is important, for example, in cases in which components of the device have been damaged, unwanted or unsuitable piece goods get to the comminution rotor or a risk to a person.
the function of the at least one hydraulic motor is reversed to that of a pump which builds up a system-damaging excess pressure against a locked position of a stationary engine of the at least one hydraulic pump.
the hydraulic oil cannot circulate between the first supply line and the first return line, so that the hydrostatic drive can be damaged.
the object of the invention is to provide a device for comminuting piece goods of the type mentioned at the outset and a method for emergency switching off of this device which survives the operating phase of an emergency run without being destroyed.
the short-circuit valve unit is in particular set up to block a flow of hydraulic oil through the first bypass line when the short-circuit valve unit is supplied with current and to otherwise release it.
the current supplying the short-circuit valve unit is obtained in particular from a current source supplying the device with power, for which purpose the device has at least one power connection.
the first bypass line is released, which enables the hydraulic oil now in a closed circuit to circulate and thus the hydraulic oil to be supplied and removed to the at least one rotating hydraulic motor. This prevents damage to the hydrostatic drive as a result of an overpressure which would otherwise build up and damage the system.
the drive motor is preferably designed as an internal combustion engine, in particular as a gasoline engine or a diesel engine. In these cases, the direction of rotation of the drive motor is unidirectional. For starting and crushing, the speed of the drive motor is preferably set to a defined target speed. In the case of a diesel engine, the combination of a diesel engine and a hydrostatic drive is also referred to as a diesel-hydraulic drive.
the hydrostatic drive preferably has at least two hydraulic pumps and at least two hydraulic motors, particularly preferably exactly two hydraulic pumps and exactly two hydraulic motors.
the at least one hydraulic pump works in particular with a variable delivery volume, while the at least one hydraulic motor works in particular with a fixed displacement.
the speed of the at least one hydraulic motor is preferably detected via a speed sensor.
at least one electromagnetic control element in particular an electric proportional valve, can be arranged on the hydraulic pump, wherein the delivery rate of hydraulic oil can be regulated by an electrical control of the at least one hydraulic pump, which can be connected to the hydraulic pump .
At least one feed pump is preferred in the at least one hydraulic pump integrated, which compensates for leakage oil losses in the first supply line and the first return line.
the comminuting rotor is preferably infinitely variable up to a maximum speed, the infinitely variable regulation of the speed of the comminuting rotor being carried out in particular by an electrical control of the hydrostatic drive.
the transmission can be designed as a belt drive or chain drive.
the short-circuit valve unit has a two-way cartridge valve and / or a pilot valve.
the pilot valve is preferably designed as a second 4 / -2-way valve with a first electrical actuating device.
the short-circuit valve unit preferably also has two pressure limiting valves.
the 2-way cartridge valve is arranged in particular in the first bypass line.
the pilot valve is connected in particular to the first pressure relief valve, the second pressure relief valve and the 2-way cartridge valve via control pressure lines in order to regulate the control pressure of the 2-way cartridge valve.
the first electrical actuating device of the 4-2-way valve is supplied with power and the control pressure is limited by the second pressure relief valve, so that the 2-way cartridge valve is in the blocking position and the first bypass line remains closed.
the first electrical actuation device is activated and switches the control pressure to the first pressure relief valve, which now releases the control pressure for the 2-way cartridge valve and thus the flow through the first bypass line.
a third bypass line is arranged between the first feed line and the second return line, an outlet valve unit being arranged in the third bypass line and the outlet valve unit being connected to the at least one hydraulic motor via a second return line.
a separate aspect of the invention relates to a device for comminuting piece goods with a drive motor, which is coupled in a force-transmitting manner to at least one hydraulic pump of a hydrostatic drive, the hydrostatic drive having at least one hydraulic motor, which is connected via a first feed line and a first return line for hydraulic oil is connected to the at least one hydraulic pump, and the at least one hydraulic motor is coupled in a power-transmitting manner to a transmission, which is coupled in a force-transmitting manner to a comminution rotor, on which tools for comminuting the piece goods are arranged, a third bypass line between the The first feed line and the second return line is arranged, wherein an outlet valve unit is arranged in the third bypass line and the outlet valve unit is connected to the at least one hydraulic motor via a second return line.
the feed valve takes a defined amount of hydraulic oil from the third bypass line and passes it on to the at least one hydraulic motor, in particular to a motor housing of the at least one hydraulic motor. This prevents an oil deficiency and a defective temperature increase in the at least one hydraulic motor in the operating phase of the shredding.
a minimum system pressure preferably a minimum system pressure of 30 bar
Leakage oil losses of the hydraulic oil that may occur in the lines of the hydrostatic drive can be compensated for during comminution by the at least one preferably integrated feed pump in the at least one hydraulic pump.
the outlet valve unit preferably has a 3/3-way valve and / or a pressure holding valve.
the respective low-pressure side of the closed third bypass line is scanned via the flushing piston of the 3/3-way valve (62) and rinsed out of this bypass line from a pressure difference of approx. 5 bar.
a pressure control valve is installed in the tank channel of the outlet valve unit. As soon as the pressure level falls below the set holding pressure, e.g. B. by too large flushing volume, the pressure control valve reduces the flushing volume and thus prevents an inadmissible pressure drop.
the outlet valve unit is followed by a second 4/2-way valve with a second electrical actuating device and / or a throttle valve.
the 4/2-way valve is in a switching position in which the hydraulic oil fed out by the outlet valve is connected to the at least one hydraulic motor via a second return line , in particular the motor housing of the at least one hydraulic motor, is passed on.
the first return line is connected via a second bypass line, the first 2/4-way valve and a throttle valve to the emergency running hydraulic motor, which is coupled to the emergency running hydraulic pump, the emergency running hydraulic motor being set up to operate the emergency running hydraulic pump by means of the to drive hydraulic oil fed out of the first return line via the second bypass line, and the emergency running hydraulic pump is connected to an emergency running hydraulic oil tank and the at least one hydraulic motor via a third return line.
the outlet valve has no function during emergency operation, since the considerably higher pressure in the bypass line blocks a check valve.
the second electrical actuating device is no longer supplied with power and switches the 4/2-way valve into a switch position in which the hydraulic oil that is fed out flows via the second bypass line to the emergency operation hydraulic motor.
the throttle valve is preferably arranged in the second bypass line.
the discharged hydraulic oil supplied to the emergency running hydraulic motor is preferably supplied to the motor housing of the at least one hydraulic motor.
the emergency running hydraulic pump sucks hydraulic oil from the emergency running hydraulic oil tank, which is preferably formed separately from other hydraulic oil tanks of the device, and feeds it to the at least one engine housing.
the hydraulic oil is supplied from the emergency running hydraulic oil tank via at least one shut-off valve with a suction function via at least one working connection of the at least one hydraulic motor which is under low pressure.
According to the invention is also a method for emergency switching off a device for crushing piece goods according to claim 1, in which the drive motor, the hydrostatic drive, the gear and the crushing rotor are driven, the short-circuit valve unit being short-circuited in the event of a power failure of the device, so that the flow hydraulic oil is released through the first bypass line.
Hydraulic oil is preferably fed out of the third bypass line from the outlet valve unit, which is arranged in the third bypass line between the first feed line and the second return line, and is conducted via the second return line to the at least one hydraulic motor.
Hydraulic oil is further preferably conducted from the working line via the second bypass line to the emergency running hydraulic motor which drives an emergency running hydraulic pump, the emergency running hydraulic pump leading hydraulic oil from the emergency running hydraulic oil tank to the at least one hydraulic motor.
a hydraulic oil volume flow Q P directed from the emergency running hydraulic pump to the at least one hydraulic motor is greater than a hydraulic oil volume flow Q M directed from the working line to the emergency running hydraulic motor.
the hydraulic oil volume flow Q P directed from the emergency running hydraulic pump to the at least one hydraulic motor is at least 1.1 times, in particular 1.5 times, the hydraulic oil volume flow Q M directed from the exhaust valve unit to the emergency running hydraulic motor .
FIG. 1 shows a hydraulic diagram of a device for crushing piece goods according to an embodiment of the invention in the operating phase of crushing.
a drive motor 10 which in the present case is designed as a diesel engine, is coupled via a distribution gear 21 to a first hydraulic pump 22 and a second hydraulic pump 23 in a force-transmitting manner.
the hydraulic pumps 22, 23 and hydraulic motors 24, 25 are via a first feed line 26 and a first return line 27 for Hydraulic oil connected together.
the hydraulic motors 24, 25 are coupled to a comminuting rotor 41 in a force-transmitting manner in order to drive the latter.
the representations of the lines with hydraulic oil have different lines. According to the bottom left in the Figures 1 and 3rd Legend is present in the lines H high pressure shown in dashed lines. Low pressure prevails in the lines N shown in broken lines. Accordingly prevail in Fig. 1 in the operating phase of shredding in the first feed line 26 high pressure and in the first return line 27 low pressure.
the lines S shown in dash-dotted lines are feed pressure lines which ensure a minimum system pressure of 30 bar in the present case on the hydraulic pumps 22, 23 and the hydraulic motors 24, 25, so that they do not suffer any damage.
the second return line 65 for returning hydraulic oil fed out of an outlet valve unit 50 to the motor housing of the hydraulic motors 24, 25 is also shown in dashed lines.
a first bypass line 51 and a third bypass line 61 are each arranged between the first feed line 26 and the first return line 27.
the first bypass line 51 leads to a short-circuit valve unit 50 and the third bypass line 61 leads to an outlet valve unit 60.
a section of FIG Figure 1 which shows the first bypass line 51 and the third bypass line 61 with the components therein, framed in bold dashed lines and as Figure 2 shown enlarged.
the short-circuit valve unit 50 has a 2-way built-in valve 54, which is arranged in the first bypass line 51 in order to block or enable the flow through the first bypass line 51.
the 2-way cartridge valve 54 is controlled by a pilot valve.
the pilot valve has a second 4/2-way valve 52, a first pressure relief valve 55 and a second pressure relief valve 56, which are connected to one another via control pressure lines, a control pressure hydraulic oil tank 57, the first bypass line 51 and the 2-way cartridge valve 54 to regulate the control pressure of the 2-way cartridge valve 54.
a first electrical actuating device 53 of the 4-2-way valve 52 is supplied with current and the control pressure is limited by the second pressure limiting valve 56 in such a way that the 2-way cartridge valve 54 is in the blocking position and the first bypass line 51 remains closed . Even when starting and shutting down the first bypass line 51 is closed due to the supply of the first electrical actuating device 53 with current. Hydraulic oil can therefore not circulate in the first bypass line 51 during starting, crushing and shutdown.
the outlet valve unit 60 in the third bypass line 61 has a 3/3-way valve 62 and a pressure holding valve (3).
the operation of the 3/3-way valve and pressure-maintaining valve 63 is as follows: The respective low-pressure side of the closed lines 61 is scanned via the flushing piston of the 3/3-way valve 62 and rinsed out of this line from a pressure difference of approx. 5 bar.
a pressure-maintaining valve 63 is installed in the tank channel of the outlet valve unit 60. As soon as the pressure level falls below the set holding pressure, e.g. B. by too large a flushing amount, the pressure control valve reduces the flushing amount and thus prevents an impermissible pressure drop.
the outlet valve unit 60 is connected via a second return line 65, in which a first check valve 64, which in the present case is designed to be spring-loaded, to a first 4/2-way valve 67, on which a second electrical actuating device 68 is arranged.
hydraulic oil fed out of the outlet valve unit 60 is fed via the second return line 65 to the motor housings of the first hydraulic motor 24 and the second hydraulic motor 25 in order to prevent an oil deficiency and an excess temperature on the hydraulic motors 24, 25.
FIG 3 shows the hydraulic diagram of the device Figure 1 in the operational phase of the emergency operation.
the drive motor 10 and the hydraulic pumps 22, 23 are at a standstill, while the comminution rotor 41 continues to rotate and drives the hydraulic motors 24, 25, which now operate like pumps.
low pressure prevails in the first feed line 26 and high pressure prevails in the second feed line 27.
a section of FIG Figure 3 that with the first bypass line 51 and the third bypass line 61 shows the components in it, framed in bold dashed lines and in Figure 4 shown enlarged.
the first electrical actuating device 53 of the short-circuit valve unit 50 is no longer supplied with current in emergency operation, so that the second 4/2-way valve 52 changes the switching position and the control pressure of the 2-way cartridge valve 54 is no longer from the second pressure limiting valve 56, but is now controlled by the first pressure relief valve 55, which is set up so that it opens the 2-way cartridge valve 54 to enable the flow of hydraulic oil for the first bypass line 51.
the hydraulic oil in the first feed line 26 and the first return line 27 can circulate through the first bypass line 51. A build-up of overpressure against the locked position of stationary engines of the hydraulic pumps 22, 23 and thus damage to the hydrostatic drive 20 is avoided.
the second electrical actuating device 68 of the first 4/2-way valve 67 is also not supplied with power in emergency operation and consequently changes the switching position of the first 4/2-way valve 67.
a second bypass line 66 in which high pressure prevails in emergency operation and which is connected to the first supply line 26 and the first 4/2-way valve 67, hydraulic oil now flows through the first 4/2-way valve 67, through the throttle valve 69 and a third pressure relief valve 70 to an emergency running hydraulic motor 71 which is connected to a Emergency running hydraulic pump 72 is coupled.
the hydraulic oil drives the emergency running hydraulic motor 71, which in turn drives the emergency running hydraulic pump 72, which supplies hydraulic oil from a separate emergency running hydraulic oil tank 73 via a third return line 74, in which a second check valve 75, which in the present case is spring-loaded, is the emergency running Hydraulic pump 72 is arranged downstream, to the hydraulic motors 24, 25, in particular to the first feed line 26 in front of the hydraulic motors 24, 25, in which there is low pressure in emergency operation.
the hydraulic oil volume flow Q P directed from the emergency running hydraulic pump 72 to the hydraulic motors 24, 25 is twice the hydraulic oil volume flow Q M directed from the outlet valve unit 60 to the emergency running hydraulic motor 71. This prevents the hydraulic motors 24, 25 from running dry and any damage associated therewith.
the emergency running hydraulic motor Hydraulic oil leaving 71 is fed to the second return line 65, which supplies the hydraulic oil to the motor housing of the hydraulic motors 24, 25.
the emergency running hydraulic oil tank 73 does not necessarily have to be physically designed as a separate component.
the emergency running hydraulic pump 72 can also pump oil from the hydraulic oil tank 57 in the emergency running.
the emergency running hydraulic motor 71 is through the return line 27 via the second bypass line 66, which has free passage to the emergency running hydraulic motor 73 in the event of a power drop in the solenoid valve 68.
the pressure from the return line 27 closes the check valve 64.
the outlet valve 60 cannot discharge oil in the emergency mode.
the respective low-pressure side of the closed third bypass line 61 is scanned via the flushing piston of the 3/3-way valve 62 and rinsed out of this bypass line 61 from a pressure difference of approximately 5 bar.
a pressure-maintaining valve 63 is installed in the tank channel of the outlet valve unit 60. As soon as the pressure level falls below the set holding pressure, e.g. B. by too large flushing quantities, the pressure-maintaining valve 63 reduces the flushing quantity and thus prevents an impermissible drop in pressure.
FIG. 5 shows a plan view of the device Figure 1 .
the drive motor 10 is coupled to the first hydraulic pump 22 and the second hydraulic pump 23 of the hydrostatic drive 20 by means of the distribution gear 21.
the hydraulic pumps 22, 23 are coupled to the first hydraulic motor 24 and the second hydraulic motor 25 by means of the first feed line 26 and the first return line 27.
a first speed sensor 28 is arranged on the first hydraulic motor 24 and a second speed sensor 29 is arranged on the second hydraulic motor 25.
the hydraulic motors 24, 25 are coupled to the transmission 30, which in the present case is designed as a belt drive.
the gear 30 is coupled to the comminution rotor 41 of a comminution unit 40.
comminution beaters 42 for comminuting a piece of goods filled via a feed chute 44 of the comminution unit 40.
a sieve basket 43 of the comminution unit 40 sifts sufficiently comminuted piece goods and does not yet collect sufficiently comminuted piece goods so that it is further comminuted before it can leave the sieve basket 43 and exit the comminution unit 40.
Figure 6 is an oblique side view of the device of FIG Figure 5 .
the comminution unit 40 with the comminution rotor 41 and the comminution beaters 42 arranged thereon can be seen particularly well here.
Figure 7 shows the circular section A. Figure 6 in a detailed view.
the short-circuit valve unit 50, the first 4/2-way valve 67, the throttle valve 69, the emergency running hydraulic motor 71 and the emergency running hydraulic pump 72 can be seen.
