  • Each half-shell 1, 2 has side walls and a bottom wall, which can be the upper or lower one according to the position of the half-shell in the tank when assembled.
  • the two half-shells can be identical or distinct.
  • said tank 10 comprises a first half-shell or upper half-shell 1 and a second half-shell or lower half-shell 2.

  • Said half-shells 1 and 2 couple together at said terminal edges 11, 21 along a horizontal coupling X-plane. Furthermore, the assembly between said half-shells 1, 2 takes place parallel to a vertical y-axis, transversal to said horizontal X-plane.
  • the solution according to the invention provides a fastening system for constraining the two half-shells 1, 2 on the vertical y-axis, allowing a gasket 4 to maintain a hydraulic sealing by its compression, and a constraint system along the X-plane which makes it possible to reduce the rotations caused by the hydrostatic thrust and the consequent separation of the half-shells which would cause the gasket 4 to lose compression and, consequently, cause the hydraulic sealing to fail.
  • a gasket 4 is in fact interposed between the first half-shell 1 and the second lower half-shell 2 for the hydraulic sealing of the modular tank 1, once assembled and filled with the fluid to be stored.
  • the internal portions of said half-shells 1, 2 of said two coupling edges 11 and 21, in other words the portions which will come into contact with the fluid to be contained, are shaped in such a way as to form an internal seat 3 for housing the gasket 4.
  • a first half-shell 1 in particular the upper half-shell 1, has an internal abutting flange 14 spaced from the respective terminal edge 11.
  • said internal abutting flange 14 is located in the internal part of the concavity of the half-shell 1.
  • the gasket 4 has a "U"-shaped cross section such as to fit onto said "L"-shaped internal flange 24 of the second half-shell 2. As can be seen, such "U"-shaped gasket 4 therefore has two side walls 41, 45 and an upper wall 43.
  • a first vertical wall 41 of the gasket 4 is provided with a plurality of protuberances 42 and is adapted to be fitted between said "L"-shaped internal flange 24 of the second half-shell 2 and the internal wall of the first half-shell 1 when the tank 10 is in its assembled configuration.
  • the upper wall 43 of the gasket 4 has an internal hollow portion 44 such that, when the tank 10 is in its assembled configuration, it is in abutment and compressed between the internal abutting flange 14 of the first half-shell 1 and the upper portion of the "L"-shaped internal flange 24 of the second half-shell 2.
  • the liquid gasket may be of the FIPFG (formed in place foam gasket) type, due to its main characteristic of being in a very viscous liquid state, it tends to fill the shape that is available (seat) and, in contact with the air, begins to polymerise forming a closed-cell foam. In this way there is a good filling of the seat using a material which is able to fulfil the hydraulic sealing tasks in the best possible way.
  • FIPFG formed in place foam gasket
  • the liquid gasket may be of the FIPG (formed in place gasket) type, due to its main characteristic of being in a very viscous liquid state, it tends to fill the shape that is available (seat) and, in contact with the air, begins to polymerise forming a compact bead. In this way there is a good filling of the seat using a material which is able to fulfil the hydraulic sealing tasks in the best possible way.
  • FIPG formed in place gasket
  • Each half-shell 1 or 2 also has, at the external portion of the respective terminal edge 11 or 21, a plurality of protruding flanges 12 or 22, in particular toothed portions 12, 22 protruding from the external body of the half-shells 1, 2.
  • Each protruding flange 12, 22 has a flat surface substantially parallel to the horizontal coupling X-plane.
  • said plurality of protruding flanges 12, 22 is arranged radially to a plane parallel to said horizontal X-plane on the respective terminal edge 11, 21, more particularly equidistantly on the perimeter of said terminal edges 11, 21.
  • Each protruding flange 12, 22 of a half-shell 1, 2 is spaced from the following flange of the same half-shell 1, 2 by such a distance that each of its two side ends overlaps a respective side end of a protruding flange 22, 12 of the other half-shell 2, 1.
  • each flange 12, 22 there are respective holes 5 arranged in such a way as to allow the passage of suitable screws 6, each screw 6 being adapted to pass through the holes 5 obtained in the free ends of a pair of flanges 12, 22, respectively a flange 12 of the first half-shell 1 and a flange 22 of the second half-shell 2.
  • Such screws 6 can be locked in place by means of bolted joints, in particular by means of nuts 7 and washers 8.
  • Such coupling means make it possible to create a simple and reliable mechanical block in the external part of the tank 10, avoiding the separation of the two half-shells 1 and 2 and acting on the gasket 4 positioned in the internal seat 3 by applying an initial compression.
  • Each flange 12, 22 is provided with a respective vertical extension 13, 23, in particular an external panel 13, 23, in particular having a flat surface with vertical development, substantially parallel to the vertical y-axis.

  • the use of the external panels 13, 23 makes it possible to align and exchange mutual forces between the half-shells 1, 2, creating continuity on the whole circumference of the tank 10. Another aspect which should not be underestimated is the effectiveness of the exchange of rheonomic constraints, given by the external panels 13, 23 which act as continuous protrusions of the half-shell 1, 2 towards the opposite half-shell 2, 1 and are not elements added at a later stage, such as the pins used in known technical solutions.
  • the external panels 13, 23 also have the function of facilitating the alignment between the two half-shells 1, 2 during the assembly and installation phase.
  • the tank 10 since the tank 10 is to be installed above ground, it has been developed in such a way that minimal fluid leakages do not occur in the area where the half-shells 1, 2 are coupled.
  • tie rods 9 placed in the internal part of the modular tank 10 when assembled.
  • Suitable seats 5 can be made on the internal flange 14, whose aim is to accommodate bolted joints, formed by screws 6, nuts 7 and washers 8, and to make the tie rod 9, preferably made of the same material as the tank 10, integral with the internal flange 14 itself.
  • each external panel 13, 23, intended as the extension parallel to the terminal edge 11, 21 of the respective half-shell 1, 2 is eight or ten times the extension in height of the vertical extension 13, 23 itself, intended as the extension along an axis parallel to the vertical y-axis.
  • the smaller number of flanges 12, 22 entails a smaller number of screws and bolts, and makes it possible to reduce the time for assembling the half-shells 1, 2 while guaranteeing the structural strength and the hydraulic sealing which characterise the invention.
  • each half-shell 1, 2 it is provided a continuous seat 3, in particular having a semicircle section, for housing the gasket (not shown in the figure).
  • each terminal edge 11, 21 it is provided an internal flange 15, 25 which continues along the entire respective terminal edge 11, 21.
  • the modular tank 10 according to the second embodiment is advantageously cheaper and requires a reduced installation time, given the smaller number of screws.
  • the resistance at the flanged part is lower and the deformations are higher.
  • Figures 13 - 18 show a third embodiment of the modular tank 10 not according to the invention.
  • the tank 10 of the third embodiment is similar to those previously described and therefore the common elements will not be described and have the same reference numbers.
  • each half-shell 1, 2 has a single external flange 16, 26 which is continuous along the perimeter of the respective terminal edge 11, 21 and projecting towards the outside of the body of the respective half-shell 1, 2.
  • each external flange 16, 26 has a flat surface substantially parallel to the horizontal X-plane.
  • each external flange 16, 26 there is a plurality of vertical extensions 17, 27, in particular, said vertical extensions are shaped external panels 17, 27.
  • Said shaped panels 17, 27 of a half-shell 1, 2 are arranged radially to a plane parallel to said horizontal X-plane on the respective external flange 16, 26, so as to leave empty spaces and are arranged alternately to the shaped panels 27, 17 of the other half-shell 2, 1.
  • each shaped panel 17 of the first half-shell 1 is arranged on the face of the external flange 16 facing the second half-shell 2
  • each shaped panel 27 of the second half-shell 2 is arranged on the face of the respective external flange 26 facing the first half-shell 1, in such a way that when the half-shells 1, 2 are assembled together, the shaped panels 17, 27 of a half-shell 1, 2 are located adjacent to the external wall of the body of the other half-shell 2, 1, fitted into the empty spaces of the mutual half-shell 2, 1.
  • Such empty spaces correspond to the interspace between two adjacent shaped panels 17, 27 of the same half-shell 1, 2.
  • Such shaped panels 17, 27 are adapted to limit the deformations induced on the coupling area, caused by the hydrostatic thrust, which could cause a loss of compression at the terminal edge 11 or 21 and at the gasket positioned in the seat 3 with consequent leakage of the fluid contained inside the tank 10.
  • the particular geometry of the shaped panels 17, 27 also makes it possible to have a resistance on the vertical y-axis given that the external flange 16, 26 of a half-shell 1, 2 intersects with the shaped panel 27, 17 of the mutual half-shell 2, 1.
  • the solution according to the present invention allows the two half-shells 1, 2 to be coupled in such a way as to have an excellent mechanical and hydraulic sealing.
  • the fastening means between the half-shells of the tank do not have added pins or mechanical inserts, using conventional fastening means such as screws and bolts. This makes it possible to reduce the assembly time of the half-shells, which can also be performed by non-professional personnel.
