Definitions

  • the invention relates to a dust protection device according to the preamble of claim 1.
  • valve bag filling machines in particular pneumatic, screw and turbine packers.
  • a double-walled filler neck is known from DE-GM 82 21 267, namely with a central filling channel and an annular channel surrounding it.
  • This has an extraction nozzle and at least one preferably flexible air supply pipe in order to enable compressed air cleaning.
  • a dust cover is missing here;
  • the escape of granular contents is to be prevented by sieves and by a cone and cylinder arrangement of the filler neck parts.
  • a suction port is necessary.
  • it requires more frequent and therefore quite a lot of time to clean or replace clogged screens again and again.
  • the swiveling arrangement of the dust hood brings great advantages.
  • the upper part and the filling tube are overlapped by the swung-in dust hood, which can not only be made smaller than conventional, therefore encloses the sack more closely and sucks in much less false air, but can also be coupled to the controls of the filling machine.
  • Optimal dedusting without dust nuisance for the personnel and a significantly improved accident protection in the event of bursting bags are achieved.
  • the suction power required (the volume throughput) of the vacuum generator is considerably lower.
  • the swung-in dust hood encloses the sack at a relatively short distance, but without contact, so that a perfect weighing can take place during filling.
  • the suction is greatly improved compared to conventional devices, since leaked dust is suctioned off both at the valve bottom corners and at the pillow needles, so that the filled bags can be removed without dust.
  • the device according to the invention is shown in the assembled state on a stem 12 of a filling machine 10.
  • This has a filler neck 14, onto which the (not shown) valve of a sack 16 can be plugged, which can be moved up and down on a sack chair 18 on the machine frame 10.
  • the main component of the device according to the invention is a dust hood 20, which has a pipe bracket 22 with suction openings 24.
  • the cross section of the tube bracket 22 can expand towards the machine 10, where its tube ends are tightly connected to tubes 26, for example by welding.
  • the tubes of the bracket 22 expediently have at least one dimension identical to the tubes 26 in order to achieve a maximum passage width.
  • the tubes 26 can in turn form a swivel bracket and each have at their lower ends 28 a swivel 30 and a hose connection 32 for connection to vacuum lines in the machine 10.
  • a swivel drive 34 is provided which engages at least on one of the tubes 26 with a joint 36.
  • a sealing strip 38 seals the dust hood 20 against the stem 12 of the machine 10.
  • the dust cover 20 covers not only the filler neck 14 but also the upper part of the sack 16, for example over a height of approximately 150 mm.
  • the suction can now be switched on and the shut-off element of the filler neck 14 can be opened so that the bag 16 is filled.
  • suction openings 24 which can be arranged at least on the front part of the dust cover 20 inside the pipe bracket 22, air is now sucked out through the pipes 22, 26 and the hose connections 32 in the flow direction illustrated by arrows.
  • the suction can also be interrupted, for example by means of a switching device (not shown) which is actuated by pivoting the dust hood 20 back.
  • the front part thereof is provided with a handle designed as a handle 40.
  • the tubular bracket 22 is designed as a carrier for the dust hood 20, which is made of, for example, transparent plastic and tapers like a canopy toward the front part.
  • the tubes 26 It is possible, but not necessary, to extend the tubes 26 to an elevated swivel bracket, which can find a stop in the front 12 of the filling machine 10.
  • Another embodiment provides that the upper ends of the tubes 26 merge directly into the tube bracket 22 and are therefore mechanically and fluidly connected to one another.
  • the cross-sections of the pipes, for example consisting of square hollow profiles 22, 26 are expediently adapted to the existing vacuum devices in order to achieve a maximum delivery rate according to the vacuum achieved.
  • an air throughput of, for example, only about 800 to 100 m 3 / h, and thus about half of the conventionally required suction power, is required. This contributes to significant energy savings.
