Definitions

  • the invention relates to a receptacle for vacuum suction and pressure systems with a monitoring device, the receptacle being connected via a line switchable from suction to pressure operation to a pump / compressor provided with a drive motor, the line having a four-way valve, the outlets of which are connected to the suction port of the pump / compressor, the line to the receptacle and the pressure port of the pump / compressor, while the fourth outlet ends freely, and a suction line is connected to the receptacle for receiving and conveying liquid, muddy, dusty or free-flowing media .
  • Such receptacles are used for disposal purposes in order to suck the media to be disposed of in liquid, muddy, dusty or free-flowing form into the container via the suction line and to store them there. After filling the container, these media are discharged via an emptying nozzle or through an openable container flap. if necessary with the help of an ejection piston.
  • the container must be large enough to hold the media, it must be capable of being placed under the appropriate negative pressure and it must be placed under considerable excess pressure, particularly when using an ejection piston or when connecting a pneumatic delivery line to the emptying nozzle.
  • there are also receptacles which, mounted on vehicles, allow the accommodated media to be transported to the emptying point.
  • Such a receptacle for vacuum suction and pressure systems which is connected via a line switchable from suction to pressure operation with a pump / compressor provided with a drive motor, a four-way valve being provided in the line, the outlets of which are connected to the suction port of The FR describes the pump / compressor, the line to the receptacle and the pressure port of the pump / compressor, while the fourth outlet ends freely, and a suction line is connected to the receptacle for receiving and conveying liquid, muddy, dusting or free-flowing media -PS 2 413 509; the container is placed in a switching position of the four-way valve by means of a pump under vacuum for sucking in liquid medium via a suction line, while after switching over the four-way valve the same container can be pressurized to over the absorbed medium to deliver a drain line again.
  • the pumps used have different vacuum or pressure capacities depending on the type and type.
  • the performance for full working operation is given by the nominal speed of the pump. This full workload is not required in all operating modes.
  • the speed of the drive motor of the pressure / suction unit is set by the operating personnel by hand, for example, using a hand throttle or the like. set. Only in favorable but rare cases is the operating option for speed adjustment within easy reach, the operating personnel must always pay attention to the speed and devote yourself to the speed setting. This additional load leads to distraction of the operating personnel for the other work and operating necessities and may also endanger the personnel or the environment.
  • the four-way valve in the line leading from the tank to the pump / compressor makes it easy to switch from suction to pressure, with just a single movement.
  • the four-way valve connects either the suction port or the pressure port of the pump / compressor to the free atmosphere, while the other of the two is connected to the receptacle via the line.
  • the vacuum or overpressure is monitored by a pressure measuring device, which is operatively connected to the speed changeover via limit contacts and, when the maximum contact (maximum overpressure or maximum vacuum) is reached, causes the speed to be switched over to a speed that is between the nominal speed for maximum performance and the idle speed. This speed, which can be switched on in this way, can be specified by the operating personnel, in accordance with the disposal task to be solved.
  • the nominal speed of the pump is reduced to the preset speed until the pressure or vacuum has decreased so far that the minimum contact is reached.
  • Hydraulic motors can be provided as drives for the pump / compressor as well as electric motors or internal combustion engines.
  • the speed can be adjusted accordingly by adjusting the hydraulic flow via a hydraulic valve with an adjustment drive.
  • Electric motors are either pole-changing three-phase motors or speed-adjustable motors with corresponding ballasts (phase gating control, variable resistors), whereby either the pole switching or the adjustment of the phase-determining resistance or the variable resistance is carried out by the adjusting drive.
  • the fuel supply is brought to the value necessary for this speed by the means adjusting the speed, the adjusting drive acting on the injection pump or the carburetor.
  • the adjustment motor as a stepper motor, since fixed speed stages can be preselected by the number of steps.
  • the introduction of a time delay in the adjustment drive causes a delayed transition of the speed and thus a delayed start-up or a delayed shutdown with corresponding slow transitions of the noise level.
  • push-button contacts are provided on the switch box in parallel with the switch contacts of the contact manometer and interact with the means switching the speed or with their adjustment drives.
  • the insertion of an emergency switch allows the pump / compressor drive to be stopped in the event of danger.
  • Signaling by optical signals in normal operation with a changed color or flashing frequency during the transition to maximum operation and finally again after changing the color and / or flashing frequency in the event of an emergency stop allows the operating state to be recognized remotely.
  • a rupture disk can also be provided as the last stage, which is designed in such a way that it can just safely withstand the maximum pressure permitted for the receptacle, but tears when this pressure is exceeded. To make sure it rips apart, that's it Destroy with a detonating pill, triggered advantageously as the last step of the sequential circuit.
  • these safety locking cams must be anchored accordingly firmly to the container, the ejection piston being designed in such a way that the ejection piston is deformed when it strikes the safety locking cams and through the deformation is deformed so that its movement in the receptacle is blocked by friction or tilting.
  • a nozzle is provided and each of the Nozzle has a shut-off valve. This means that each chamber can be shut off individually, regardless of the switching of the four-way valve. If the connecting line is connected to the suction port via the four-way valve, Opening the valve assigned to the suction chamber, the suction operation for receiving the media to be disposed of can be carried out.
  • valve assigned to the pressure chamber it is also advantageous to open the valve assigned to the pressure chamber in order to prevent the discharge piston from being displaced by the overpressure (prevailing relative to the suction chamber).
  • the four-way valve is switched to pressure mode and the valve assigned to the suction chamber is closed.
  • the compressed air flows from the compressor into the pressure chamber via the four-way valve; the discharge piston can move towards the end of the container under the effect of the excess pressure. It does not matter whether the ejection takes place via the open container lid or through the opened emptying nozzle.
  • Pressure relief is provided both by the opened container lid and by the opened emptying nozzle, so that pressure build-up in the suction chamber, which leads to pressure equilibrium (and thus to piston stoppage), is prevented.
  • the discharge piston After emptying, the discharge piston must return to its old position. To do this, the four-way valve is switched to suction mode and, when the valve associated with the suction chamber is closed, the valve associated with the pressure chamber is opened. The negative pressure that arises in the pressure chamber moves the suction piston back into its rest position.
  • the single-chamber container 1 which can also be mounted as a container on a vehicle - is provided with an openable cover 1.5 and has an emptying nozzle 1.3 at the lower end of the cover or bottom of the container, which is closed by a valve. For emptying, either the valve of the emptying nozzle 1.3 is opened or the entire cover 1.5 is opened (with hinges and cylinders, not shown).
  • a suction dome 1.9 with a suction hose connection is provided on the top of the container, the connected suction hose being guided, for example, over an extension arm or being able to be unwound from a horizontally lying suction hose reel arranged on the connection.
  • a vacuum breaker or pressure relief valve 1.8 is also provided on the container and can be operated remotely.
  • a nozzle 1.7 is also provided, which is closed with a rupture disk.
  • the container 1 is connected via line 2 to a four-way valve 3.
  • a contact manometer 6 Arranged in the train of the line is a contact manometer 6, the limit contacts for pressure and / or vacuum, each equipped with a maximum and a minimum contact, are connected to the switch box 7 via the lines 6.1 and 6.2.
  • the connecting line 2 is connected to the connector 3.2 of the four-way valve, the connector 3.1 is firmly connected to the suction port of the pump 4 and 3.3 to the pressure port of the pump 4.
  • the fourth connection piece 3.4 opens freely into the atmosphere.
  • the pump / compressor 4 is driven by means of a drive motor 5 via a reduction gear 5.3, which permits a rough adaptation of the nominal motor speed to the nominal pump speed.
  • the operating speed is selected using means for setting the speed 5.1, a drive 5.2 making it possible to adjust the operating speed to the (maximum) nominal speed.
  • the operating speed can be pre-selected on the setting means for the respective disposal case.
  • the control is in principle carried out by the contact manometer 6, the maximum and minimum contacts of which give switching impulses to the switch box 7 either only for vacuum or for both pressure and vacuum via lines 6.1 and 6.2. Parallel to the maximum and minimum contacts are the buttons 7.1, which allow manual intervention in the automatic system.
  • the switch 8 can also be used for manual operation only, by means of which the automatic system can be switched off.
  • an emergency stop switch 7.2 is connected to the switch box, it goes without saying that a plurality of electrically switched emergency stop switches can be provided, which are arranged in such a way that they can be easily reached by the operating personnel during normal operation of the receptacle.
  • the actuator 5.2 for the means for speed change is activated via the switch box 7, the speed change switches in steps with a delay or the drive motor 5 switches from operating speed to nominal speed by slow transition. Due to this run-up, including the suction vacuum pump, the pump output is increased, the pressure gauge moves in the direction of maximum contact. If this is reached, another pulse goes to the switch box 7, which reverses the speed change again makes. If the pressure does not follow the reduced speed, e.g. due to a malfunction, the emergency stop is activated and the pump drive is shut down. If this does not cause a change in the limit state either, the vacuum breaking valve or the pressure relief valve 1.8 is opened, thus forcing a change in the limit state. Should this valve also fail, the rupture disk 1.7 (unless it has burst due to the overpressure reached) is finally destroyed by mechanical action, for example by means of a detonated detonating pill.
  • Fig. La shows the receiving container 1, which is designed here as a two-chamber container.
  • the discharge piston 1.4 separates the pressure chamber 1.2 from the suction chamber 1.1.
  • the suction chamber 1.1 serves to collect the media to be disposed of, while the pressure chamber 1.2 is essentially responsible for the ejection and movement of the ejection piston 1.4.
  • Both lines are connected to line 2 via shut-off valves 2.1 and 2.2.
  • the connection for the suction hose 1.9 is of course in the area of the suction chamber 1.1.
  • Both chambers are provided with the remotely operable vacuum break or pressure relief valves 1.8 near the end position.
  • safety locking cams 1.6 that can be inserted into the interior of the container are provided on the side of the openable container lid 1.5, near the end of the container. These locking cams - also remotely operated - have the task of stopping the ejection piston 1.4 that is in motion before it emerges from the receptacle 1.
