Definitions
- the present invention relates to a container according to the preamble of claim 1.
- Bitumen has the characteristic of being solid at room temperature and becoming liquid at a higher temperature, for example 160 ° C. It can therefore easily be transported frozen at room temperature but it must be heated to be poured into a transport container; similarly, to remove it from the container, it is necessary to heat it until liquefaction.
- European patent application 0101635 describes a container for transporting bitumen, "which comprises a heating pipe arranged in a serpentine shape at the bottom of the container permanently, inlet and outlet orifices for this pipe passing through the vertical walls of the container to allow the mounting of a source of heating fluid at the inlet opening in the vertical wall at the bottom of the container.
- the heating surface of this pipe in contact with the bitumen is configured so that the interface between the pipe and the solid bitumen created a nesting of the pipe in the solid bitumen, which is why, during heating, the block of bitumen solid remains essentially immobile with respect to the pipe and liquefaction is carried out so that the heat dissipated from the pipe must pass through the entire layer of already liquefied bitumen before reaching the solid bitumen.
- the solid bitumen block remains essentially stationary relative to the pipe and the liquefaction is carried out so that the heat dissipated from the pipe must pass through the entire layer of already liquefied bitumen before reaching the solid bitumen.
- FIG. 5 shows a diagram of bitumen liquefaction as obtained with a container according to the European document described above, while FIG. 6 shows such a diagram corresponding to the present invention.
- the container according to the invention is produced according to the definition of claim 1.
- the substantially planar upper wall is slightly inclined relative to the horizontal plane and the enclosure has an outlet orifice immediately in the vicinity of the lowest point of the inclined surface.
- the essentially planar upper wall of the snake may comprise at least two flat parts with different inclinations forming at least one inclined line of intersection of the two parts of the surface, line whose lowest point is located in the vicinity of the outlet orifice .
- the pipe serpent for heating fluid can comprise at least one inlet and at least one outlet for the heating fluid which can be a combustion gas.
- the inlet of the snake may be provided with a means of establishing communication with the outlet of a gas or MPLACEMENT burner.
- this means can for example be constituted by a fixing mechanism for this burner.
- the snake comprises in the vicinity of its inlet a combustion chamber having walls different from those forming the heating fluid duct, combustion chamber which can be constituted by a cylindrical wall whose length is at least equal to the length of a gas or oil burner flame.
- the wall or the continuous upper surface of the snake may have a rectangular shape extending across the entire bottom of the enclosure, the orifice this outlet of this enclosure can be arranged in the center, in the corners, or at a place any short side of this rectangle.
- the exit of the enclosure can be in a corner of the rectangle and the line of intersection between them inclined flat parts of the continuous surface, that is to say of the upper ⁇ sroi of the snake goes towards this same point and at its lowest point also in this corner.
- the inlet of the snake can be in the center of the short side of the rectangle, and the snake can consist of a central duct crossing essentially the length of the container, and at least one return on each side of this central duct.
- the outlet (s) can be connected to vertical conduits which pass vertically through the enclosure in the vicinity of corners formed by intersections of the adjacent vertical walls and perpendicular to each other, vertical conduits which may have a section circular or rectangular cutting.
- the heating means may include a symmetrical deflector situated at the level of the communication between the
- FIG. 1 represents a plan view of an embodiment of a container according to the present invention
- FIG. 2 represents a cross section along 2-2 of the container of FIG. 1,
- FIG. 3 represents a longitudinal section along 3-3 of the same container
- FIGS. 4 and 4a represent two other embodiments of a container according to the present invention.
- FIG. 5 represents a diagram of liquefaction of bitumen in a container according to the prior art
- FIG. 6 represents a diagram of liquefaction of bitumen in a container according to the present invention.
- Figure 1 we see a container 1 from the top with a characteristic shape of a rectangular parallelepiped, the side walls being designated by the references 5 and 5 " .
- heating means having a surface or top wall 2 and a bottom wall 3, which together with FE U ITY walls REPLACEMENT vertical separation 15 a duct arranged in a snake.
- the upper wall 2 carries the material to be transported, for example bitumen, and is supported by the vertical and longitudinal walls 15 on the lower wall 3.
- the empty space forming the serpentine conduit between the upper 2 and lower 3 walls is intended to receive the heating fluid.
- This heating fluid can be created for example by an oil or gas burner (not shown) injecting the flame or the combustion gases through an inlet opening 6 of the heating fluid directly through a short side wall 5 ′, of the container in the snake.
- the snake being made up of sections 9 which are arranged side by side, the heating fluid is forced to pass under the entire surface of the upper wall 2.
- the combustion gases are preferably evacuated from the end of the snake by a conduit or a vertical chimney 8 in contact on its sides with the material to be heated and higher than the maximum level of this material.
- the chimney 8 can be adjacent to a side wall 5.
- the combustio gases exit through the outlet opening 7 at the top of the chimney
- the lower wall 3 d of the serpent is covered with a thermal insulator 10.
- an opening is provided in a side wall 5 ′ of the container 1 at the top of the upper face that the upper wall 2
- the flow can be further facilitated by tilting the bottom so that the opening 4 is the lowest point l of the bottom.
- the flow opening 4 placed at the lowest point of container on line 63 which is constituted by the fon of a very flat V obtained by inclinations 1 symmetrical with respect to median axis, inclinations that FIRE I REPLACEMENT are constituted by parts 2 'and 2 "of the wall 2.
- FIG. 3 the entire snake formed by the walls 2 and 3 is inclined towards the side, where the flow opening 4 is located according to an inclination 11.
- the inclinations 11 and 12 can be combined in the same container or else only one of them can be incorporated in.
- the opening 4 is generally closed by a closure (not shown) and is open only during the evacuation of the material after it has been heated to liquefaction.
- FIG 4 shows another embodiment of the heating means, in which the snake consists of a central duct 64 and two return ducts 64 ', one on each side of the central duct.
- the central duct 64 comprises in the vicinity of the inlet 20 a combustion chamber 21, a chamber which consists of a cylindrical wall 21 'whose diameter corresponds to the vertical distance between the lower and upper walls of the heating means, and whose the length is dimensioned in order to guarantee that the burner flame (not shown) is maintained inside the combustion chamber 21.
- the heating means comprises a deflector 22 arranged on the short face of the container and opposite the inlet 20 of the combustion chamber, a deflector which serves to reduce turbulence during the deflection of the gas stream leaving the central duct 64 and rotating in the return duct 64 'at the loops 22'.
- REPLACEMENT SHEET Figure 4a shows an embodiment of the present invention similar to that of Figure 4, however having a slightly modified snake.
- the central duct 64 is followed by two return conduits 64 ′ which are again followed by two double return conduits 64 ".
- This geometry makes it possible to arrange the chimneys 8, through which the heating fluids escape, in the vicinity of the rear wall 5b, opposite the wall 5a, through which the heating fluid is introduced by means of a burner.
- FIG. 5 schematically shows the consecutive steps of the reliquefaction of the solid material 52, inside the enclosure 50.
- the enclosure is filled with solid material 52 with the exception of a empty space 51.
- the enclosure 50 comprises a heating pipe 54, the serpentine configuration of which produces three sections as illustrated in each position ae in FIG. 5.
- FIG. 6 shows the same steps of liquefying solid material inside an enclosure 50 which comprises a heating means 62 according to the present invention, heating means which has been illustrated diagrammatically as comprising a perfectly flat upper wall 2, it being understood that the liquefaction takes place in a completely analogous manner on an upper surface comprising slightly inclined parts.
- Position b shows the conditions inside the enclosure after a certain initial heating time, during which a thin layer 60 between the upper wall
- Positions c, d and e show the decrease in block 52 during the continuation of heating, during which the lower surface of block 52 always remains in very good thermal contact with the upper wall 2 of heating means 62, contact by which the passage of heat given off by the wall 2 is transmitted inside the block 52 in the fastest and most efficient way. In this way the time required to liquefy the solid block 52 in an enclosure 50 according to FIG. 6 is considerably shorter than that required by a heating means as illustrated in FIG. 5.
- Line 63 can be arranged according to the location of the flow opening 4.
- the containers 1 are constructed, apart from the features mentioned above, according to the usual techniques for this product with longitudinal 13 and transverse 14 profiles to give a solid background to the
- REPLACEMENT SHEET container with corner profiles 16 and side walls 5.
