Definitions

  • the present invention relates to an apparatus and a process for filling containers with granular or powdered materials, in particular with finely divided solids with a high air content, as well as to the container itself.
  • finely divided silica is a product having an extremely low compacted bulk density of about 40 to 50 g/1. Owing to its fine structure, finely divided silica is capable of binding a very large amount of gas, for example air, so the product is put into a quasi-fluid state of about 20 to 30 g/1.
  • the bags consist of three to four plies of paper, and one ply of the paper may additionally be laminated with polyethylene as a barrier against penetrating moisture. To achieve the desired air permeability during the filling process, all plies are microperforated. This has the effect that the product is compressed as it is introduced into the bag and its filling density increases relative to the natural pour density.
  • a process and a receptacle for repeated filling with and emptying of pourable product having a low pouring density is known from EP-A-0 773 159.
  • the woven fabric receptacle described therein, the so-called big bag or also super bag consists of flexible air-permeable woven fabric, preferably a single or multiple ply of plastic woven fabric with at least one inlet.
  • This woven fabric receptacle is also filled using vacuum filling systems. A vacuum is applied to the woven fabric receptacle and the product is aspirated through the open inlet into the woven fabric receptacle until a predetermined filling weight is achieved. The issuing gas is distributed over the entire surface of the woven fabric receptacle.
  • DE-A-198 39 106 describes flexible large containers for finely divided solids having a high air content for repeated filling using vacuum filling systems, which consist of at least two superimposed plies, an inner ply consisting of uncoated air-permeable woven fabric and an outer ply being dustproof and being coated with a moisture barrier and these plies being mutually connected by a special seam in such a way that the container may only be aerated through it.
  • the DE-A-198 39 106 describes a particular process for filling this large container, with which the filling material is subjected to preliminary deaeration prior to filling and a further deaeration via the seams of the fabric is carried out during filling.
  • the preliminary deaeration and therefore partial compaction of the filling product are also effected by the application of vacuum.
  • a drawback of the process described in DE-A-198 39 106 is the extremely high expenditure on apparatus as vacuum systems are required for both preliminary compaction and filling of the large container. Despite this expenditure, the filling capacity is still too low, so the process described in DE-A-198 39 106 is uneconomical overall.
  • an apparatus for filling containers in particular with finely divided solids having a high air content, comprising a feed nozzle which may be introduced into the feed orifice of the container, wherein the feed nozzle is so designed that the solids may be introduced under pressure and the container is surrounded by a two-part or multi-part cage (3) .
  • the present invention also relates to a process for filling containers, in particular with finely divided solids having a high air content, by arranging an air-permeable container in an apparatus according to the invention, air-tight connection of the container to the feed nozzle, filling of the container under pressure and removal of the filled container.
  • Another subject matter of the invention is a flexible container for finely divided solids for the repeated filling and draining, characterized in that it consists of at least two ply, one above the other, wherein one play consists of an air-permeable supporting material that is preferably non-coated and the other ply consists of a filter material.
  • the air- permeable, supporting material can be arranged on the outside and filter material on the inside.
  • the container according to the invention can be designed for optional amounts of finely divided filler materials.
  • the container according to the invention can preferably be used for amounts up to 1,200 kg. In contrast, containers according to prior art could only accommodate filling amounts of 90 to 100 kg.
  • the material used for each ply can be commercially available material.
  • the container according to the invention permits a dust- free filling through compacting on the inside of the container, in particular using the apparatus according to the invention, wherein clearly higher bulk weights can be achieved.
  • the finely divided material can be drained from the container according to the invention through a preceding fluidization and simultaneous conveying.
  • a further subject matter of the invention is a corrugated cardboard container (carton) for finely divided materials, which can be ventilated.
  • This container is characterized by its design, for which one side of the corrugated cardboard consists of a highly air-permeable paper and the inside undulation (s) as well as the other sides and intermediate plies consist of non air-permeable standard corrugated cardboard with a microperforation.
  • the container corrugated cardboard container
  • the container has a supporting as well as filtering design.
  • the highly air-permeable inner ply acts as a filter for the product and permits the air to escape.
  • the outer ply and the intermediate ply (plies) and the undulation (s) absorb the forces, but permit the air to escape.
  • air is moved quickly through the walls and the product can be highly compacted inside the container with considerably higher filling weights than is possible with known systems (up to 1,200 kg as compared to the known 90-100 kg, depending on the product type) .
  • the container according to the invention is shown schematically in Figure 5.
  • Finely divided solids having a high air content may be poured with adequate compression of the solids in high capacities using the apparatus according to the invention and the process according to the invention, without high expenditure on apparatus.
  • finely divided granular powdered solids having a high air content and selected from pyrogenic oxides, precipitated oxides, carbon blacks and modifications may be poured.
  • the apparatus according to the invention has a special feed nozzle which is equipped with a flexible , sealing, skin, and therefore allows dust-free pressure filling.
  • the feed nozzle may be deformable and may therefore allow the filling of containers of various sizes.
  • the cage which is an important component of the apparatus according to the invention has to withstand, in particular, the pressure required. At the same time, the cage gives the container adequate support during the filling process, to ensure that the container withstands the pressure applied and keeps its shape during the filling process.
  • Containers of a wide variety of shapes and of various materials may be filled in the apparatus according to the invention.
  • the materials may be: air-permeable plastic woven fabric, preferably polypropylene woven fabric, plastic woven fabric, textile woven fabric, cardboard, paper, paper plastic woven material, plastic non-woven fabric, textile non-woven fabric or composites of the aforementioned materials.
  • the filling pressure is generally 0 to 8 bar, preferably 0 to 2 bar and particularly preferably 0.2 to 1.2 bar.
  • the containers employed in the apparatus according to the invention using the process according to the invention may be of any conventional shapes and materials.
  • the containers may have a base area selected from a group consisting of polygon, circle, semicircle, ellipse, trapezium, triangle, rhombus, square and rectangle or a star-shaped base area.
  • the containers may also have the shape of a hood, of assembled pockets or the shape of a tied-up bag.
  • the cage contacts the container to be filled, as uniformly and snugly as possible. It is therefore expedient if the cage substantially corresponds to the shape of the container. Additional fittings in the cage allow adaptation to the respective container to be filled.
  • the cage (3) itself is also gas-permeable ' .
  • the cage may have walls with openings or with adequate porosity. This may be achieved, for example, by openings in the cage walls.
  • the cage walls are produced from a material selected from perforated plate, mesh or netting, woven fabric or sintered material or a mesh material, because this allows high gas permeability with adequate stability to ensure that the container does not explode even under high filling pressures.
