Definitions

  • the invention relates to a method and an apparatus for Avoidance of product dust or product gas leakage Filling with solid or liquid dosing systems.
  • Such metering devices usually include a product storage silo tapering from top to bottom, on its lower front is a vertical one Filler tube emerges. The passage through the filling pipe can can be opened and closed using a slide. That Filling tube goes up to the upper part of the container, which is a certain amount of the product to be filled. The For this purpose, the container is packed in one during dosing and filling appropriate location attached.
  • closed systems that cause lower emissions.
  • Such closed systems are known to be achieved in that between the container and a tight connection is created to the filling pipe.
  • facilities are necessary which evacuate or evacuate the air when filling a product is displaced from the container.
  • the suction device consists, for example, of containers a funnel-shaped sack nozzle, the upper front side with a bowl-like cover is closed.
  • the fill pipe penetrates the cover in the middle.
  • An upper one Section of the fill tube protrudes from the top of the cover forth.
  • a lower section protrudes into the sack nozzle.
  • the sack nozzle and the cover are gas-tight with each other connected.
  • a suction or aspiration tube opens into the cover. This aspiration tube is on its lower face connected gastight to the cover.
  • an annular, inflatable inflation hose For attaching a bag-shaped container, for example an annular, inflatable inflation hose can be used, which is attached to the outside of the sack nozzle.
  • the outer diameter of the inflation hose is not inflated smaller than the inside diameter of the sack-shaped Container, so that the upper end portion of the container over the lower end section of the sack nozzle and over the inflation hose can be put up. If the inflation hose is put on Container is inflated, then its outer diameter increases and the wall of the inflation hose is pressed against the container wall. This fixes the container and at the same time one tight connection between the sack nozzle and the container is achieved.
  • the present invention sets itself the task based on the prior art mentioned at the outset To create methods and an apparatus with which the leak of product dust or gas when filling powdery or liquid products with the help of solid or Liquid dosing systems can be reliably avoided.
  • the object is achieved by a method and a device with the features of Claims 1 and 4 solved.
  • Advantageous further training the invention are the subject of the dependent claims.
  • the drawings show a device for avoiding Product dust or product gas leakage, which e.g. in a conventional metering device 1 for filling sack-like Container 5 is installed.
  • the metering device 1 is with a Suction device of a known type equipped, which consists of a Sack socket 2 with inflation hose 6, a cover 3 and one Aspiration or suction tube 4 exists.
  • the embodiment of the proposed device has a first flushing pipe 7, which penetrates the cover 3 and along the filler tube 8 below the cover 3 extends to the lower end of the filling tube 8 (see FIG. 1a, 1b and 2).
  • the lower end face of the flushing pipe 7 is with the lower end of the filler tube 8 flush.
  • the piercing point the flushing pipe 7 in the cover 3 is gas-tight.
  • the proposed device has a second one Flushing pipe 15, which also outside the cover 3 runs parallel to the filling pipe 8 and the inflation hose 6 from penetrates downwards.
  • the two breakthrough points on Inflatable hose 6 are gas-tight.
  • the deflection ring 13 below the inflation hose 6 is a flat, hollow deflection ring 13 arranged.
  • the lower end of the second flush pipe 15 opens into this deflection ring 13.
  • the deflection ring 13 has several Nozzles 14, which open laterally outwards.
  • the nozzles 14 are regular along the circumference of the deflector ring 13 Intervals arranged. If gas is blown into the purge pipe 15 , this gas gets into the deflection ring 13 and flows out through the side nozzles 14.
  • a filling process proceeds as follows: First, an empty container 5 is attached to the sack nozzle 2 with the aid of the inflation hose 6.
  • the deflection ring 13 has the upper inner wall section of the container 5 from the inflation hose 6.
  • the first Flushing pipe 7 gas especially air, in a defined manner and Blown vertically into the container 5.
  • the gas stream 12 will through the surface of the filled product 10 upwards redirected. It flows due to the suction of the aspiration or.
  • Suction pipe 4 through the space between the bag neck wall and the filling pipe wall upwards and tears the Dust particles with them.
  • the gas infused with dust becomes finally sucked into the aspiration or suction tube 4.
  • the gas can then be returned to the purge pipe 7 become. A closed one can therefore be used for the purge gas Realize the cycle.
