Definitions

  • the present invention relates to a device for sealing and evacuating (or pressurizing gas) a particularly high-viscosity liquid in a container whose interior has a cylindrical inner contour.
  • the containers used in this context are usually barrels whose interior has a cylindrical, in particular circular cylindrical inner contour (possibly with stiffening longitudinal beads), wherein the inner contour usually opens without tapering into an outer opening of the interior, namely in the barrel opening to the outside.
  • air in the system is a highly detrimental event because, from a certain amount and size of air pockets, the feed pumps can not compress them against the material in the system and / or because the introduced air results in mixing ratio problems or even process termination.
  • users take the risk of removing (and thus losing) a large amount of material from the venting device in order to ensure as much as possible that no air remains in the system.
  • An apparatus according to the preamble of claim 1 is for example off DE 10 2007 003972 known.
  • the present invention is based on the object to provide a device for sealing and evacuating or gas pressure applying a particular pasty liquid in a container, which is process and user friendly, as well as cost-saving and in particular overcomes the disadvantages mentioned above.
  • the device according to the invention serves for sealing and evacuating or pressurizing gas, in particular, with a pasty liquid in a container, for example in the process engineering processes described here above.
  • the invention prevents air entry into the system, risk of splashing, loss of material and danger to users when inserting the device and in particular when changing the container.
  • the device according to the invention has a seal which is arranged on a circumference of the device and adapted to be sealingly insertable into the cylindrical inner contour of a container (in particular one of the containers already described).
  • the inner contour of the container to which the device according to the invention is adapted, without rejuvenation opens into an opening to the outside of the container.
  • the inner contour is preferably circular cylindrical; It is particularly preferably the circular cylindrical inner contour of a smooth-walled sheet steel lidded barrel with clamping ring closure (the diameter in a common embodiment is 572 mm).
  • the inner contour, to which the invention is adapted can have beads (or other structures, for example for barrel reinforcement), in particular in the direction of the cylinder axis.
  • the seal is preferably adapted, for example, by elastically nestling in the shape of this structure.
  • the seal of the device according to the invention delimits an outer side of the device from an inner side of the device.
  • a connection device On the outside of the device, a connection device is arranged, which is adapted to the (direct) connection of a vacuum pump.
  • a line can also be connected to the connection device (indirectly), which is then in line connection with a vacuum pump.
  • Vauum pump or "evacuation pump” stands for a gas pump or plant which is designed to generate negative pressure and / or (in particular for dismantling an empty drum in the processes described above) also overpressure.
  • overpressure can also be introduced from an air pressure network, which is often available as an installation in production facilities.
  • the device according to the invention also has an open-pored porous wall of the inside of the device, which is in line connection with the connection device.
  • the porous material allows gas to be sucked off (in particular air), while it represents a kind of labyrinth seal for the particularly pasty material.
  • the porous wall is preferably made of aluminum granules-epoxy resin composite material such as Metapor® the company Hohnen & Co, Bielefeld.
  • Metapor® the company Hohnen & Co, Bielefeld.
  • all materials and structures are suitable (and are meant to be porous with open-pore), let the air through and no liquids.
  • tiles such as Goretex® is conceivable, whereby such non-inherently stable materials and structures may require a shape-retaining support structure.
  • the porous wall can by a transitional cavity in the line connection with the connection device, wherein the transition cavity preferably has a larger line cross-section than the line connection.
  • the air in the container especially on the material surface
  • the material in the form of inclusions or bubbles, especially close to the material surface
  • the (conveyor / dosing) pump When placing the follower plate can so directly through the follower plate, the air in the container (especially on the material surface), in the material (in the form of inclusions or bubbles, especially close to the material surface), in the (conveyor / dosing) pump and as far as possible be sucked in the material conveying lines.
  • a porous pore diameter of between 0.0001 and 1 mm has proved suitable for the porous wall.
  • a mean pore diameter between about 0.001 and 0.01 mm is suitable.
  • a mean pore diameter between 0.1 and 1 mm for the sealing of a pasty liquid having a viscosity between 50,000 and 200,000 mPas is advantageous such as Raku-Tool® CP-6070 from Rampf Tooling or a similar material from other manufacturers.
  • connecting device can when moving out (by means of, for example, hydraulic, pneumatic or electric actuator) of the device from the container (for example, to exchange an empty barrel against a full) and the air are introduced so that no negative pressure obstructs the disassembly by moving out of the follower plate.
  • an active "pneumatic" moving out of the device by pumping air under the device and the device is pushed out of the container - and more preferably the combination of active retraction by means of actuator and compressed air entry under the follower plate.
  • the invention together with the control provided thereon, can ensure that fully automatic retraction and extension of the follower follower plate becomes a safe and problem-free standard process, which also saves costs because no material is lost.
  • the device 2 illustrated in the figure is used for sealing and evacuating or pressurizing a particularly pasty liquid 4 in a container 6 with gas pressure.
  • the device 2 has an annular rubber seal 8, which is arranged on a circumference of the device 2. It has four axially adjacent, radially outwardly projecting lamellar rings 10 with staggered outer diameter (but also all sorts of other seal types and shapes are conceivable such as only one or more sealing rings with solid or hollow (hose-like) cross-section 8 adapted to be circumferentially sealingly insertable into the circular cylindrical inner contour 12 of a steel sheet drum 6.
  • the inner contour of the drum 6, to which the device 2 according to the invention is adapted, ends without tapering into the drum opening 16 to the outside of the sheet steel lidded drum. wherein the drum opening 16 for storage and transport of the therein filled high-viscosity material 4 with a metal lid with clamping ring closure (not shown) can be closed.
  • the seal 8 of the device 2 defines an outer side 18 of the device 2 from an inner side 20 of the device 2.
  • a connection device 22 in the form of an internal thread 22 is arranged on the outer side 18.
  • a line (not shown) can be connected to the connecting device 22 (namely screwed in), which can then be connected to a pneumatic feed pump (electric or pneumatic vacuum pump, not shown).
  • the pump is designed to generate negative pressure and (in particular for dismantling the device 2 from the drum 6 after its emptying) also overpressure. Via the connecting device 22, however, air pressure can also be introduced from the conventional pressure network (not shown).
  • the device 2 also has an open-pore porous wall 24, which forms an annular region 26 of the surface on the inner side 20 of the device 2.
  • the porous wall 24 is in line connection 25 with the connecting device 22.
  • the porous material 24 can be sucked gas 28 (in particular air) through, while it represents a kind of labyrinth seal for the pasty material 4.
  • the porous wall 24 is made of aluminum granule-epoxy resin composite having an average pore diameter of 0.4 mm.
  • the high-viscosity material 4 is, for example, Raku-Tool® CP-6070 from Rampf Tooling.
  • the inserted porous molding 24 is sealed with sealing rings 33 in the joining gaps to the base body 34, so that neither material nor compressed air can search the porous molding 24 a "different way" to the transition cavities 30, as only by the porous material 24th
  • the aggregate 32 is an element of a feed pump, through which the viscous liquid 4 can be conveyed out of the drum 6 safely and without air inclusions. This is done after placing the follower plate 2 and the evacuation of the air 28 the gap between the device 2 and the (not visible horizontal) liquid level of the viscous liquid 4 and also from the ducts of the pump unit 32nd
