Arrangement for transporting highly dispersed powders, and method of filling and emptying the same

Abstract

A container with a top edge, a bottom edge and a rear side provided with a door, containing an inliner, wherein the inliner comprises at least two layers located one above the other, an inner layer consisting of uncoated, air-permeable fabric and an outer layer being coated so as to be dust-tight and to provide a moisture barrier, these layers being connected to one another by a special seam such that dust-free venting of the receptacle is possible only through this seam, the inliner being fastened in a reversible manner in the container and having at least one filling opening and an emptying opening.

1 . A container with a top edge, a bottom edge and a rear side provided with a door, containing an inliner, wherein the inliner comprises at least two layers located one above the other, an inner layer of uncoated, air-permeable fabric, and an outer layer being coated so as to be dust-tight and to provide a moisture barrier, these layers being connected to one another by a seam such that dust-free venting of the receptacle is possible only through this seam, the inliner being fastened in a reversible manner in the container and having at least one filling opening and at least one emptying opening.  
   
   
       2 . The container of  claim 1 , wherein the filling opening and the emptying opening are located adjacent each other on the bottom edge of the rear side of the container.  
   
   
       3 . The container of  claim 1 , wherein the inliner is configured such that the seams of the inliner are located in the longitudinal direction of the container, on the top and bottom edges of the container.  
   
   
       4 . The container of  claim 1 , wherein the filling opening of the inliner is in the form of a filling connector comprising a fabric hose which is fixed to the inliner.  
   
   
       5 . The container of  claim 1 , wherein the emptying opening is similar, in terms of shape and size, to the filling opening.  
   
   
       6 . A method of filling and emptying a container of  claim 1 , wherein, the inliner is filled with contents via the filling opening by means of dense-stream conveying until a predetermined filling weight has been reached, the dense-stream conveying system is removed, and the filling opening is closed.  
   
   
       7 . The method of  claim 6 , wherein filling takes place by means of a diaphragm pump.  
   
   
       8 . The method of  claim 6 , wherein, a filling grid is inserted into the rear-side door opening of the container.  
   
   
       9 . A method of emptying a filled container of  claim 1 , wherein the emptying opening of the inliner of the filled container is connected to a discharge arrangement and a suction device and opened, and the contents are sucked out of the inliner with the aid of the suction device.  
   
   
       10 . The method of  claim 9 , wherein the discharge device comprises a pressure-pulse generator which ensures friction-free product discharge of the material during emptying by the flowability of the material being increased via pressure pulses.  
   
   
       11 . The method of  claim 9 , wherein the discharge device is fitted to the container.  
   
   
       12 . The method of  claim 9 , wherein the container is located in an oblique position during emptying.  
   
   
       13 . The method of  claim 12 , wherein said oblique position is greater than 30° from horizontal.
