Definitions
- the invention relates to a method for operating a water jet cutting system, in which a liquid-particle mixture resulting from a cutting process is fed to a collecting device by means of a pumping device, according to the features of the preamble of claim 1.
- a liquid-particle mixture is created, with the added solid particles (such as sand, for example) from the component particles separated during the cutting process, for example metallic particles, so that this liquid-particle mixture has highly abrasive properties having.
- a pump is used to discharge this mixture from the water jet cutting system to a collecting basin, which sucks this mixture and conveys it in the direction of the collecting basin.
- the liquid-particle mixture collected in the collecting basin can be further processed in a suitable manner, for example disposed of or recycled, this not being the subject of the present invention.
- the pump wears out very quickly, so that either the entire pump or those parts of the pump that suck in the liquid-particle mixture from the water jet cutting system and convey it to the collecting basin have to be replaced. During this time there is disadvantageously a standstill of the water jet cutting system, which is undesirable because no components can be cut during this time.
- the invention is therefore based on the object of improving a method for operating a water jet cutting system in such a way that the liquid-particle mixture resulting from the cutting process can be continuously removed and the wear on the pump is significantly reduced.
- the liquid-particle mixture is fed to a filter system, some of the particles from the liquid Particle mixture settles in the filter system and is collected there and the remaining liquid-particle mixture reaches the pumping device, the settled particles still being flushed out of the filter system by means of the pumping device in predeterminable time cycles.
- the filter system prevents the pumping device from being subjected to the complete liquid-particle mixture which is sucked in by it by the water jet cutting system.
- a certain amount of abrasive particles which are composed of the cutting particles (such as sand) and the particles released by the component to be cut (such as steel), are already separated to a certain extent beforehand.
- the filter system is designed to at least partially, ideally completely, separate these solid particles from the liquid-particle mixture coming from the water jet cutting system. These can accumulate in the filter system. It could be thought of after a certain time, when a certain amount of such separated solid particles has accumulated, to remove them from the filter system. However, this would mean that the operation of the water jet cutting system would have to be interrupted, which, however, is not desired. For this purpose, it is further provided according to the invention that the deposited and thus collected particles continue to be flushed out of the filter system by means of the pump device in predeterminable time cycles.
- the water jet cutting system can advantageously continue to be operated, in particular continuously, without there being an interruption when the deposited and collected particles have to be removed from the filter system.
- the particles are removed from the filter system by rinsing, using the liquid that is also used for the cutting process in the water jet cutting system. It therefore no additional, in particular no other type of liquid is required.
- a closed circuit is thus formed in which the liquid-particle mixture originating from the water jet cutting system is at least partially, ideally completely, separated from the solid particles and is also used to remove the particles deposited and collected in the filter system to remove from the filter system, in particular to rinse.
- the supply of the liquid-particle mixture from the water jet cutting system via the pumping device and the filter system to the collecting device and the flushing of the filter system are controlled by a control unit.
- a control unit This means that the process of rinsing out the filter system can either be controlled manually or carried out automatically.
- the actuators required for the flushing process, in particular valves, can be controlled, possibly remotely, by an operator operating the control unit.
- the amount of particles deposited in the filter system is determined and the predefinable time cycle is started as a function of the determined amount. This makes it possible to automate the flushing process very well, in particular using the control unit. This automation takes place in particular depending on the degree of filling of the
- the degree of filling being a measure of the amount of particles deposited in the filter system. If this degree of filling exceeds a specifiable, especially the upper threshold value, the rinsing process is started.
- the end of the rinsing process can be fixed, for example after a predefinable period of time.
- the length of the time interval for the rinsing process can be smaller, equal to or greater than the time interval during which no rinsing takes place (pause).
- Figure 1 a first embodiment of an inventive
- Figure 2 a further embodiment of an inventive
- FIG. 3 a filter system, which in one of the two according to the invention
- Water jet cutting machine can be used.
- the reference numeral 1 is provided with a water jet cutting system 1, which is representative of all cutting systems in which a component with a liquid-particle mixture is cut.
- the liquid can be, but does not have to be, water, just as the particles used for cutting, which are mixed with the liquid, are sand, but can also be other particles.
- the component generally consists of a metallic material, although other, in particular non-metallic materials can also be cut with such a system.
- the liquid-particle mixture formed after the cutting process which may also be provided with particles of the component that have been loosened by the cutting process, is sucked in by a pumping device 2 and conveyed towards a collecting device 3, for example a collecting basin.
- a filter system 4 is connected between the water jet cutting system 1 and the pumping device 2.
- the liquid-particle mixture emitted by the water jet cutting system 1, as defined above and simply referred to as “mixture” in the following, is fed to the filter system 4 via a line 5 in the flow direction 6.
- a line 7 leads from the filter system 4 with a flow direction 8 of the mixture to the pumping device 2 and from there via a line 9 in the flow direction 10 to the collecting device 3.
- This configuration is for the devices as shown in FIGS. 1 and 2 , identical.
- a further line 11 branches off from the line 9 behind the pump device 2, through which the mixture can be conducted in the flow direction 12 to the filter system 4.
- the line 9 (after the branch of the line 11) there is a valve 13.
- a further valve 13.1 is arranged in the line 11, behind the branch from the line 9.
- a further line 14 leads from the filter system 4 in the flow direction 15 to the collecting device 3.
- valve 13.1 interposed in the line 11 is closed, whereas the valve 13 in the line 9 is open, so that the ongoing operation of the waterjet cutting system 1 is guaranteed, but at the same time that which occurs during the cutting process Liquid-particle mixture can reach the collecting device 3 via the filter system 4, conveyed by the pump device 2.
- the liquid-particle mixture is not supplied to the filter system 4 from the water jet cutting system 1 during the rinsing cycle (rinsing process). In such a case, however, it is necessary for the filter system 4 to be rinsed with a liquid that does not come from the water jet cutting system 1. It could be thought of supplying the liquid that is present in the collecting device 3 to the filter system 4 via appropriate lines and valves during the flushing.
- valve 13.1 in the line 11 is opened by a control device (not shown here) or by hand, and analogously to this the valve 13 in the line 9 is closed, so that the mixture which leaves the pump device 2 and already contains a reduced proportion of solid particles is only fed to the filter system 4 via the line 11 through the opened valve 13.1.
- the particles that have settled in the filter system 4 are rinsed out of the latter and fed to the collecting device 3 via the line 14 in the flow direction 15.
- valve 13.1 is closed again and the valve 13 is opened so that the liquid-particle mixture delivered by the pumping device 2 (with a reduced proportion of particles that is retained (separated) in the filter system 4) only overflows the line 9 is fed to the collecting device 3 in the direction of flow 10.
- FIG. 2 shows an alternative device in which, as in the device according to FIG.
- I I intermediate valve 13 is present. From the line 11, behind the branch from the line 9 and upstream of the valve 13, another line 16 leads in the direction of flow 17 to the collecting device 3, a further valve 18 being interposed in the line 16. In addition, a line 19 leads in the flow direction 20 from the filter system 4 to the collecting device 3. The line 19 also has an interposed valve 21, the line 19 downstream of the valve 21 being connected to the line 16 downstream of the valve 18. In this device, the valve 13 is located behind the branch at which the line 16 branches off from the line 11 and in front of the filter system 4.
- This alternative device also implements the inventive concept that the liquid-particle mixture is fed to a filter system 4, with some of the particles from the liquid-particle mixture settling in the filter system 4 and being collected there, and the remaining The liquid-particle mixture reaches the pumping device 2, the deposited particles continue to be flushed out of the filter system 4 by means of the pumping device 2 in predeterminable time cycles.
- the valves 13 and 21 are closed, while the valve 18 and also the valve 25 is open, so that the mixture that leaves the filter system 4 via the line 7 with only one A reduced proportion of solid particles is fed to the pumping device 2 or is sucked in by it in order to then feed it to the collecting device 3 via the lines 9 and 16.
- the liquid-particle mixture continues to be fed from the water jet cutting system 1 to the filter system 4 during the flushing cycle and at least part of the liquid-particle mixture, reduced by some of the particles, is used for flushing out the deposited particles from the filter system 4 used.
- the cutting system 1 can also be operated normally with this alternative device, which is shown in FIG. This means that the liquid-particle mixture is collected via the filter 4 in the manner described above, while the cutting system 1 continues to be operated without restricting its operation. If it was found that a certain volume of the liquid-particle mixture (either by measuring the volume, after time or the like) has been separated (collected) by means of the filter 4, the rinsing process takes place in which the particles collected in the filter 4 are removed be flushed out of this by means of the pump 2 and collected in the collecting basin 3.
- valve 13 which is arranged in the flow direction 12 in the line 11 from the pumping device 2 to the filter 4 is closed, as is the valve 21 in the line 19.
- valve 18, which is arranged in the line 16 is open. This means that the liquid-particle mixture sucked out of the filter 4 by the pump device 2 is fed to the collecting basin 3 via the two lines 9 and 16 (in each case in the direction of flow 10 and 17).
- this liquid-particle mixture a certain part, preferably a large part, of the solid particles coming from the cutting system 1 is separated via the filter 4 and has been collected there.
- the cross-sections of the two lines 10, 16 are of the same size, so that over these 100% of that volume flow that is emitted by the pump 2 in equal parts (50% each) via the lines 9, 16 in the flow direction 10, 17 is fed to the collecting basin 3.
- the cross section of that line 7 which is led in the flow direction 8 to the pump device 2 corresponds to the cross section of that line which leads out of the pump 2 and which is then divided into the two lines 9, 16.
- valves 13, 18 and 21 are actuated. This is done manually or automatically via a control device, in the latter case ideally simultaneously.
- the valve 13 is opened, just like the valve 21.
- the previously open valve 18 is closed so that no volume flow can be fed to the collecting basin 3 via the line 16 (that part behind the valve 18).
- the volume flow emerging from the pumping device 2 is divided into two partial volume flows, with one partial volume flow being fed to the collecting basin 3 as before in the flow direction 10 via the line 9.
- the further partial volume flow is fed via the now open valve 13 via the line 11 arranged behind it in the direction of flow 12 to the filter 4 for rinsing. After rinsing, this partial volume flow, enriched by the particles collected in the filter 4, leaves the filter 4 via the line 19 in the flow direction 20 via the opened valve 21 and is fed to the collecting basin 3.
- valve 25 is open during the collection of the particles (while the valves 13, 21 are closed and the valve 18 is open) and during the flushing process, in which the valves 13, 21 are open and the valve 18 is closed, the valve 25 is closed.
- the cross-section of the line 7, which leads in the flow direction 8 into the pump device 2 is exactly twice as large as the respective one Cross-sections of the lines 11, 16 and 19 behind the pump device 2.
- the cross-sections of the line 9 and 16 are selected to be the same, as well as the cross-sections of the line 7, which leads into the pump device 2, and the cross-section of the line section, which comes from Pump device 2 leads out and which is divided into the two lines 9, 11.
- FIG. 3 shows, by way of example, the configuration of a filter system 4 which can be used in the devices according to FIGS. 1 and 2. It can be seen that a vibration device 22 is arranged in an upper region of the filter system 4.
- the filter system 4 also has a filter container 23, in which a collecting container 24 is provided at its lower end.
- the filter container 23 and the collecting container 24 are connected to one another via a valve 25.
- Within the filter container 23, separating webs 26, 27, 28 and 29 are arranged, for example in the arrangement shown.
- These partitions can be impermeable, for example plate-shaped. Alternatively or in addition, they can be designed as sieves, grids or the like.
- separating webs 26-29 have the effect that the liquid-particle mixture supplied via the line 5 is not unhindered to the Line 7 can reach, and thus allow the particles to settle (ideally the settling of the complete proportion of the particles, in practice a larger part of the particles fed in) inside the filter container 23 (there on the bottom).
- the valve 25 is open during this collecting process, ie also during normal operation of the water jet cutting system 1, so that the particles can settle in the collecting container 24 below.
- the valve 13 according to FIG. 1 or the valves 13 and 21 according to FIG. 2 are closed, so that no liquid-particle mixture can move through the collecting container 24 via the lines 11, 14/19.
- the particles in the collecting container 24 are removed from the liquid-particle mixture, which comes from the line 11, rinsed out and carried away via the line 14/19 in the direction of the collecting device 3.
- the water jet cutting system 1 can also continue to operate while this rinsing process is being carried out.
- the vibration device 22 can be arranged on the cover 30 and removed with it.
- a vibration device 22 can also be arranged, for example, on the side wall of the filter container 23.
- the vibration device 22 can be switched on as required. Either it is always switched on while the waterjet cutting system 1 is in operation or it is only switched on during the rinsing process (and thus not during the collection and settling of particles in the filter container 23 or the collecting container 24) or it is only switched on during the collection and settlement of particles and not switched on during the rinsing process. As an alternative to this, it can also be thought of operating the vibration device 22 only during certain time intervals, that is to say continuously alternating on and off turn off again. In a preferred manner, the vibration device 22 is always switched on or operated when the valve 25 during the
- the rinsing process is open.
- valve 13 in the line 9 is open, whereas the valve 13.1 in the line 11 is closed.
- the valve 25 is also open so that the particles from the liquid-particle mixture leaving the cutting system 1 can be collected in the filter system 4.
- the vibration device 22 is also activated.
- valve 13 in the line 9 is closed, whereas the valve 13.1 in the line 11 is open. During this time the valve 25 is closed and the vibration device 22 is deactivated.
- valve 18 in the line 16 is open, whereas the valve 13 in the line 11 and the valve 21 in the line 19 are closed. During this time the valve 25 is open and the vibration device 22 is activated.
- valve 18 is closed, whereas the valves 13 in the line 11 and 21 in the line 19 are open.
- valve 25 is closed and the vibration device 22 is deactivated.
