Definitions

  • the invention relates to a two-chamber disposal container with an axially displaceable discharge piston, which separates a first chamber of the container, which is designed as a suction chamber and is provided with an openable cover, from a second chamber, which is designed as a pressure chamber, the discharge piston having at least one guide ring adjacent to the container wall and is provided between the outside of the guide ring and the inside of the container wall and has a plate which blocks the lumen of the guide ring, in particular for containers mounted on disposal vehicles.
  • ejection pistons are also used, which divide the disposal container into two chambers, namely into a front pressure chamber and a rear suction chamber, the latter pointing towards the discharge opening.
  • This suction chamber serves as a collecting container for the media to be accommodated
  • the front chamber is used as a pressure chamber for moving the ejection piston
  • an overpressure means a movement towards the rear end of the container and thus an ejection of the medium
  • negative pressure means a retraction of the ejection piston into its normal position.
  • Both chambers are connected by separate suction and compressed air lines to a vacuum or compressed air pump, which are switched via corresponding changeover valves so that the suction chamber is under vacuum during suction operation and no overpressure is built up in the pressure chamber that the pressure chamber is pressurized when ejected and that finally after the ejection of the piston is withdrawn by negative pressure in the pressure chamber.
  • a separate shut-off valve is provided in each of the lines: these shut-off valves make it possible to control the pressure in each of the two chambers.
  • the discharge piston In the practice of actuating and moving the discharge piston, the discharge piston receives an excessive movement (sliding) impulse due to the overloading of its pressure surfaces due to the excess pressure in the pressure chamber, and overruns or breaks off the intended end stops at the discharge opening of the disposal container , "shoots" through the opening of the container into the open and poses a significant risk to people and Represents material in the environment. Such incidents are also due to operating errors and - as has been shown in practice - the previously known safety measures are not sufficient to bring the sliding movement of the ejection piston under control.
  • an inflatable seal with a pressure fluid is able to brake and even stop a piston that is in motion. It is sufficient for this that the seal is inflated with compressed air, the compressed air from the pressure chamber already being sufficient with suitable seal dimensions. Especially with the problem of sudden acceleration of the piston due to a (higher) overpressure generated in the pressure chamber, such a braking effect can prevent the piston from "going over", since the braking effect increases progressively with the pressure in the pressure chamber. It goes without saying that others too Pressurized fluid sources can be used; It is also possible to switch over the inflation pressure, for example when the piston has traveled a distance that corresponds almost to the container length.
  • the known piston stops are used to mechanically stop the piston, the kinetic energy of the piston, which the piston stops cannot withstand, being at least partially converted into deformation work by a "crumple zone" of a compressible piston attachment and thus reduced.
  • the piston stops absorb the kinetic residual energy. It is advantageous to provide the compressible attachment with predetermined breaking points so that tongues occur which, as a result of the pre-deformation, interact with the container wall as brake tongues in an outward direction.
  • outflow flaps can also be provided which can be opened when the trigger is activated. Such discharge flaps can also be formed by tearing open the plate that closes the lumen of the guide ring of the ejection piston or by means of rupture disks, whereby the release can take place mechanically (via chain or other tension links) or electromechanically (via electrically ignited explosive charges or the like).
  • the rupture disks are designed so that they just do not respond to a load at the pressure in the pressure chamber, which is required for a slow sliding movement of the ejection piston, but tear open when this pressure is exceeded. It is also advantageous to vent the pressure chamber by a discharge channel that is released by the discharge piston when the discharge piston has reached its maximum position. When moving into this maximum position, the cross section of the outflow channel can also be successively released in that the cross section becomes larger the further the piston is extended. A triangular-shaped channel is advantageous because it is easy to manufacture.
  • Another advantageous application for the limit contacts of the pressure measuring device is to open the valve in the line through which a pressurized fluid, usually compressed air, is supplied to the inflatable seal of the ejection piston, so that the seal is inflated and the ejection piston is inflated by the inflated one Seal is braked to a standstill.
  • a pressurized fluid usually compressed air
  • safety lock stops are provided at the end of the container, which, when the ejection piston is opened, cause further deformations or canting of the ejection piston in addition to the deformations already caused by the limit stops and thus cause the ejection piston to slide on prevent.
  • the arrangement of these safety locking stops at a gap to the limit stops has the consequence that the deformations caused by the limit stops have weakened the stiffness of the compressible attachment and thus have a more effective effect on the crumple zone of the compressible attachment.
  • the drive takes place either via a separate drive source or from the drive of the main vacuum / pressure unit, with a countershaft for speed adjustment and clutches expediently being provided can be seen with which either both units can be operated simultaneously or each individually.
  • a silent circulation promotion can be carried out via a bypass from the suction port to the pressure port, or a valve lift ensures that the delivered and unnecessary compressed air is blown off.
  • the described automatic functions eliminate operating errors when operating the two-chamber disposal container, in particular when ejecting with the ejection piston, and ensure the safety of people and materials in the area. All security systems can be used next to each other, especially all security systems with the additional compressed air pump.
  • the main vacuum pressure unit 5 is arranged, the suction connection of which is connected to the suction chamber 3.1 (FIG. 2) via a line (not shown).
  • the pressure port is fed to a four-way valve 8 via a line 5.1.
  • An outlet of the four-way valve establishes the connection 5.2 to the pressure chamber 3.1 (FIG. 2) of the disposal container.
  • the pressure measuring device 9 is arranged with - not shown - limit contacts.
  • FIG. 2 shows a section through the location of the container 3 at which the ejection piston 10 is located, which separates the suction chamber 3.1 from the pressure chamber 3.2.
  • the suction piston 10 is guided by the guide ring 11, the lumen of which is closed by an inclined plate 12.
  • the all-round sealing profile rings 13 which - set relatively hard - essentially serve to guide the ejection piston.
  • two sealing profile rings 13 are provided, between which an inflatable seal 14 is arranged.
  • the lumen of the inflatable seal 14 can be connected via a line 16 to a supply for a pressure fluid.
  • the front end of the ejection piston is provided with a compressible attachment 11.1, which is deformable when driven against the ejection piston stops 21 (FIG.
  • the disc 12 is provided with parallel or annular grooves 15, which represent tearable predetermined breaking points, it is further connected via a chain 17, attached to the eye 16, to a fixed part of the container (not shown in detail). If the chain is stretched when it is stretched by the chain length, the predetermined breaking points tear open, the torn points of the plate 12 form outflow openings through which the pressure can escape from the pressure chamber 3.2 of the container 3.
  • the chain 17 acts as a trigger for the valve 23 inserted into the line 16, which in the end position - with the chain 17 tightened (as shown) flips the shift lever 23.1 of the valve 23 and thus the line 16 with the connects a compressed air source leading spiral line 16.1.
  • a pressure fluid is conducted into the annular chamber of the inflatable seal 14 and expanded, which - depending on the pressure applied - acts as a brake or stop member.
  • this chain 17 can also be connected to a trigger which switches off the compressed air supply to the pressure chamber 3.2, opens a vent valve for the pressure chamber 3.2, releases rupture disks or the like.
  • the container wall 3 shows a section of the container end with the piston stop 21 and with an outflow channel 19.1, which opens into an outflow pipe 18, which is closed with a pendulum-mounted flap 20 which is tightly fitting in suction mode.
  • the container wall 3 is raised in a wedge shape in the region of the container apex approximately twice the width of the seals 13, 14, 13 and approximately over such a length and opens into an outflow line 18, which is then closed with the pendulum flap 20.
  • the ejection piston stops 21 are located approximately half the distance from the end flange 9.1 and - FIG. 4 - are placed at a distance of 90 ° from U-iron pieces which are adapted to the curvature of the container wall 3.
  • safety stop stops 22 are provided in the area of the upper part of the container, which are set against the limit stops 21.
  • the sliding surfaces of the safety stop stops can also be designed as an inclined plane.
