Problems solved by technology

[0014] The disadvantage of the process described in DE-A-198 39 106 is that both the pre-compaction and the filling of the large container require the use of a vacuum system, which leads to very high equipment costs
But the filling capacity is still too low, despite the large expenditures, so that the process described in DE-A-198 39 106 is not economical as a whole

Embodiment Construction

[0048] As shown, the preferred embodiment of the invention comprises a frame 1 provided at the top with two rails 2 along which the two halves 3a and 3b of the housing 3 can be moved by conventional drive means .

[0049] exist figure 1 with 2 In the illustrated embodiment, the housing has a square base area and is divided diagonally into the two halves 3a and 3b. This ensures that the two halves are easily separated from the filled container, even if the container is squeezed against the casing due to high filling pressures.

[0050] The casing also has two sleeve halves 4a and 4b which, when closed, surround a feed nozzle (not shown).

[0051] Such as figure 2 As shown, the casing 3 is open at the bottom and the container rests on a bracket or pallet 5 during the filling process. Furthermore, it is an advantageous configuration, as shown in the figure, that the filling nozzles are arranged symmetrically with respect to the frame 1, so that the housing halves 3a can be...

Abstract

The present invention discloses a flexible container for being repeatedly filled and discharged finely crushed solid material, the flexible container consists of at least two layers, one layer is formed by a breathable bearing material, the other layer is formed by a filter material. The present invention also discloses a breathable filtered corrugated cardboard container for finely crushed solid materials, which has the following structure: one side of the corrugated cardboard is composed of highly breathable paper and an internal corrugated structure, the other side and the middle layer is composed of a non-breathable standard corrugated cardboard processed out of micropores.

Description

[0001] This application is a divisional application of an invention patent application with an application date of July 9, 2002, an application number of 02813899.6, and an invention title of "equipment and method for filling granular or powdery materials into containers". technical field [0002] The present invention relates to an apparatus and a method for filling a container with granular or powdered material, especially finely divided solid material with a high air content, and also to the container itself. Background technique [0003] Various problems arise when handling pourable finely divided solid materials, such as finely divided silica, with high air content and very low pour density. Manufacturers and end-users are confronted with the fact that these materials generate dust with even slight air drafts. In order to prevent damage to the health of persons handling articles due to inhalation of dust, the formation of dust must be avoided. In addition, low filling ...
