- Powdery substances are also conveyed and transported in a controlled atmosphere in the chemical, pharmaceutical and food industries.
- the known systems for conveying powdery materials of this type are mostly matched in their construction to the product to be conveyed subsequently; these systems are one-offs that require high investment costs.
- two material flows - in particular in opposite directions - are fed to the container space and swirled in the container space.
- the material flows it has proven advantageous for the material flows to be supplied approximately tangentially, preferably also at approximately the same container height, so that their paths interlock. In this way, an intimate swirl is created.
- the material flows are preferably also introduced at an angle of inclination to a radial plane of the container, i.e. the material flows are introduced inclined downwards.
- each of the material flows is removed from a common vessel and a cycle is thus generated.
- the swirled material flows from the container space should be introduced into the common vessel and withdrawn from it together.
- Another approach which can also be combined with the above method, is to remove each of the material flows from a separate vessel. In the latter case, different substances are preferably mixed together.
- the lower end of the container preferably sits on a collecting vessel and is provided at the other end with a connecting piece.
- At least one reflection device can also be arranged in the flow path in the interior of the vessel as a baffle, on which the particles bounce off and are pressed back into the stream.
- the outlet element at the bottom has at least two outlet elements for one line each - connected at the other end to one of the connecting pieces -; according to a further feature of the invention, the latter is intended to connect the outlet member of the reaction vessel to an extension piece of the container, that is to say to enable a circuit.
- a branch line is connected to the line; this branch line is then connected at another end to a vessel which contains one of the powdery substances.
- Another device serves to change the temperature of the conveyed material, in which at least one temperature generating device crossing the conveying path of the conveyed material is arranged in the interior of the container, preferably a warm air generating device.
- at least two tubular hollow profiles of uniform cross section should advantageously be joined axially through an intermediate chamber, and the hot air generating device should be arranged in the intermediate chamber; the latter is preferably inclined to the longitudinal axis of the device.
- Fig. 2 the enlarged cross section through Figure 1 along the line II-II;
- FIG. 4 an enlarged cross section through FIG. 3 corresponding to the position of line II-II in FIG. 1;
- a device 10 for the pneumatic conveying of powdery materials with a small grain size range has a collecting vessel 12 as the main container with a cylindrical vessel wall 14 of a height h and an outer diameter d.
- the interior 15 of the collecting vessel 12 is closed at the bottom by a housing base 16, from which a bowl-like base piece 17 projects in the axis A of the vessel.
- the interior 15 of the vessel is spanned by a domed lid 18, from which - axially to the axis of the vessel A - a cylindrical container 20 made of electrolytically polished stainless steel with a length a of, for example, 600 mm protrudes; whose interior 22 of a diameter di of here 200 mm serves as a swirl chamber.
- This container interior 22 is from spanned a plate-like sieve 24, above which protrudes from a container cover 26 a - here T-shaped - connector 28.
- a vacuum line and a conveying gas line can be connected at one end to the latter, at least the latter containing a shut-off valve. Such valves are indicated by way of example at 29 in FIG. 3.
- Two lateral attachment pieces 30, 30 a lead into the container interior 22, which - according to FIG. 2 parallel to each other on both sides of a common diametral - at an angle w from here about 15 ° to a radial plane E - downward towards the vessel axis A.
- a butterfly valve 32 is integrated in each of these connecting pieces 30, 30 a as a blocking element in a connecting flange 34.
- a hose-like line 40 or 40 a leads to a radial pipe 38 of that bowl-like base piece 17.
- the line 40 a on the right in FIGS. 1, 3 is only in sections shown.
- the interior 22 of the container 20 is fed tangentially through the connecting piece 30, 30 a and the lines 40, 40 a two streams of powdery substances in the conveying direction x or y and according to Fig.2 on the inner surface of the container 20 in opposite circular paths x ⁇ or yi convicted. This creates a swirling of the substances and their intimate mixing. This mixture reaches the interior 15 of the vessel thanks to a central bottom opening 23 which is designed to be closable.
- a central bottom opening 23 which is designed to be closable.
- the collecting vessel 12 a which is suspended in a support ring 51 of a chassis 52 , is funnel-shaped, and its tip 46 merges into a T-shaped pipe connection 47, on the transverse pipe 48 of which the two lines 40, 40 a are connected.
- the latter are fixed in loops 53 of that support ring 51.
- an intermediate piece is integrated here as a lock insert 50, to which a branch line 42 or 42 a is connected; on the other hand, this ends with an insert tip 44 or 44 a made of rigid material.

Powders can be obtained automatically from the vessels 54, 55 - for example from barrels, sacks - or directly from process equipment granulators or the like. be sucked in. After the mixing process has been completed, the system can be emptied fully automatically and completely into the next processing step.
