Description

REINFORCED TANK FOR TRANSPORTING AND STORAGE OF LIQUIDS
The present invention relates to a reinforced tank for transporting and storage of liquids .
In the state of the art , tanks for transporting and storage of liquids are known, caged in metal cages . The metal cage serves to protect the tank and to contain the deformations of the shape of the tank itsel f . The tanks in fact have a parallelepiped shape which on one hand allows for rapid stacking, but on the other hand does not allow for balanced distribution of stresses on the surface of the tank . The metal cage is thus necessary to reinforce the shape of the tank and contain the deformation thereof .
In the state of the prior art , caged tanks comprising a bottom portion comprising a recess towards the inside of a volume of the tank . The recess comprises an inner wall where a through hole is drilled between the outside and the inside of the volume of the tank to which a tap is applied to extract the fluid contained in the tank .
The wall of the tank which is immediately above the recess for the tap is particularly subj ected to deformations , in particular to bulging, because no vertical tubular element of the metal cage can pass in front of the tap, and thus no vertical tubular element passes in front of this portion of the wall .
In the state of the prior art , the part of the wall of the tank immediately above the recess for the tap comprises a top recess that partially limits the bulging deformation of the wall of the tank, but often deformations of the wall occur that are so large as to cause breakages in this part of the wall , resulting in the dangerous release of the fluid contained in the tank .
An obj ect of the present invention is to make a tank for transporting and storage of liquids that is reinforced and reduces the bulging deformation of the wall arranged above the recess designed for the tap .
According to the invention, such obj ect is achieved with a tank for transporting and storage of liquids according to claim 1 .
The features and advantages of the present invention will be more apparent from the following description, which is illustrative and not limiting, with reference to the attached schematic drawings in which : figure 1 is a perspective view of a portion of a tank for transporting and storage of liquids according to the present invention, wherein the tank comprises a bottom portion of a side wall comprising a bottom recess . The bottom recess comprises a through hole mounting a tap to extract the fluid contained in the tank . The side wall comprises a top recess arranged immediately above the bottom recess for the tap, wherein the top recess comprises substantially vertical ribs , wherein the top recess is symmetrical with respect to a vertical geometric axis of symmetry; figure 2 is a front view of a detail of the tank of figure 1 where the tank caged in a metal cage comprising vertical and hori zontal tubular elements is shown . It should be noted that there is no vertical tubular element of the cage in front of the tap ; figure 3 is an enlarged view of detail A of figure 2 showing a left portion of the top recess of the side wall ; figure 4 is a cross-sectional view along line IV- IV of figure 3 ; figure 5 is a longitudinal sectional view along line

Additionally, preferably, the widening of the width of the first longitudinal rib 20 is not symmetrical , but it widens only towards the centre of the top recess 10 , expanding its extreme portions 22 towards the first concave portion 12 in the direction of the vertical geometric axis of symmetry S .
Even more preferably, the top recess 10 comprises two second longitudinal ribs 21 arranged symmetrically with respect to the vertical geometric axis S .

Preferably, the second concave recess portion 12 of the left portion shown in figures 4 and 7 provides a single bending radius , which is a third bending radius R_12 .
Preferably, the third bending radius R_12 is between the first bending radius R_l l l and the second bending radius R_112 .
The second concave recess portion 12 comprises a central portion arranged above the vertical geometric line of symmetry S which is arranged on a first bottom geometric plane © that is parallel to the geometric plane 2 identi fied by the outer surface of the side wall 101 , but at a smaller height than the outer surface of the side wall 101 as the first bottom geometric plane © represents the most recessing level of the tank of the top recess 10 .
Preferably, a fourth bending radius R_20 of the first longitudinal rib 20 is smaller than a fi fth bending radius R_21 of the second longitudinal rib 21 .

The shape of the top recess 10 along the longitudinal direction is discussed below .
With particular reference to figures 3 , 5 , 6 , and 8 , the top recess 10 provides that the first 11 and the second concave recesses 12 comprise a substantially central concave portion 15 that develops along the longitudinal direction and two convex portions 13 and 14 that develop along the transverse direction which are respectively a top convex portion 13 which starts from a top edge 17 of the top recess 10 and a bottom convex portion 14 which starts from a bottom edge 18 of the top recess 10 .
Preferably, a sixth bending radius R_13 of the top convex portion 13 is lower than a seventh bending radius R_14 of the bottom convex portion 14 , as the bottom edge 18 of the top recess 10 borders a more pronounced top edge of the bottom recess 110 , while the top edge 17 of the top recess 10 is level led with the rest of the side wall 101 .
Preferably, the top edge of the bottom recess 110 can be at a height level greater than the geometric plane 2 identi fied by the side wall 101 , in the sense that it rises towards the outside of the tank 100 with respect to the geometric plane 2 .
