Double-walled tank container

Abstract

The present invention concerns a double-walled tank container ( 1, 12, 13, 14 ) whereby the inner container ( 2, 3 ) is stored at the bottom inside the outer enclosure ( 6 ) by a spacer consisting of several spacer pieces ( 16 ). The spacer provided, which is preferably placed near a front saddle ring ( 12, 13 ), imparts transportation and storage stresses between the inner tank ( 2, 3 ) and the outer enclosure ( 6 ) and consequently between the inner container ( 2, 3 ) and the frame ( 14 ) of the tank container. The spacer ( 16 ) can be laid out in such a way that it absorbs shocks and/or defines a hollow space ( 10 ). This hollow space can serve as a thermal insulation or for the installation of temperature equalization devices, mediums or a leak detector fluid.

1 . Tank container with a double-walled tank ( 1 ) connected on both sides by a vaulted interior and exterior bottom plate ( 2 ,  8 ), whereby the outer tank enclosure ( 6 ) is connected with a frame ( 14 ), characterized by 
 a spacer placed on one end between the exterior bottom plate ( 8 ) and the interior bottom plate ( 3 ).    
     
     
         2 . Tank container as described in  claim 1 , whereby the spacer is attached (in particular welded or glued) to either the interior or the exterior bottom plate ( 3 ,  8 ).  
     
     
         3 . Tank container as described in  claim 1 , whereby the spacer is composed of several spacer pieces ( 16 ,  16   a ) and/or is placed in a conical ring arrangement concentric with respect to the tank axle and following the exterior of the interior bottom plate and the interior of the exterior bottom plate, respectively.  
     
     
         4 . Tank container as described in  claim 1 , whereby the spacer is located inside a front ring ( 12 ), which is part of a front saddle mounting ( 12 ,  13 ) and connected with the exterior bottom plate ( 8 ).  
     
     
         5 . Tank container as described in  claim 1 , whereby the cylindrical section of the outer enclosure ( 7 ) between the exterior bottom plate ( 8 ) and the inner tank ( 2 ,  3 ) encompasses only in part in a lower area.  
     
     
         6 . Tank container as described in  claim 1 , whereby the outer enclosure ( 6 ) completely encompasses the inner tank ( 2 ,  3 ) and is attached to the inner tank ( 2 ,  3 ) only with spacers.  
     
     
         7 . Tank container as described in  claim 1 , whereby the hollow space ( 10 ), which is defined by the spacers or spacer pieces ( 16 ,  16   a ), between the outer enclosure ( 6 ) and the inner tank ( 2 ,  3 ) is filled with a test liquid or a temperature equalization medium.  
     
     
         8 . Tank container as described in  claim 1 , whereby spacers or spacer pieces ( 16 ,  16   a ) made of a shock-absorbing material and the hollow space ( 10 ) between the inner tank ( 2 ,  3 ) and the outer enclosure ( 6 ) are filled with a second material. The first material includes in particular of high-resistance PUR/PIR, elastomers and plastics, and the second material includes of PUR/PIR border foams.  
     
     
         9 . Tank container as described in  claim 1 , whereby the interior of the inner tank ( 2 ,  3 ) is equipped with a coat, in particular a phenolic resin or vitreous enamel coat, or the inner tank ( 2 ,  3 ) is made of a brittle material, in particular glass.  
     
     
         10 . Tank container following  claim 1 , whereby the clearance between the inner and outer enclosure is equipped with a temperature equalizing devise.
