Definitions

  • Each of the cells has a cylindrical portion and a curved bottom portion and engages the inner face of the outer member along at least a part of the outer face of the cylindrical portion of the cells.
  • the curved bottom portion of each of the cells forms an outer recess substantially at the point of reaching the cylindrical portion thereof, and recess is adapted to receive sealingly and flush the cylindrical portion of the next adjacent cell.
  • the present invention relates to compartmented tankers from laminated resins.
  • Tankers made of laminated resins have hitherto been madein a way similar to metal tankers, more particularly by a construction employing welded hoops, ends and wave baffles.
  • the results have not been satisfactory and it has in particular been found that the inner partitions or wave baffles become detached and leakage occurs at places because of imperfect sticking of the ends to the rings.
  • An attempt has been made to obviate this disadvantage by the .use of rings which fit over the edges of curved ends which are molded separately by means of a recess over a specific length terminating in a shoulder, the assembly forming a core which is then completely covered with a layer of resin.
  • plastics suitable for the production of tankers wchemically withstand some of the products that they-have to contain to a varying degree; Corrosive products, such as some conc'entrated acids, may ultimately affect the walls.
  • Corrosive products such as some conc'entrated acids
  • the surface condition of the walls in contact must be extremely smooth and durable to prevent any growth of germs and bacteria; no matter how well made plastic walls are, their structure necessarily results in scaling and microscopic fissures in which microorganisms can develop without being readily detached with conventional means, even the most modem means used with metal tankers for example.
  • the compartmented tanker is characterized in that cells, tubular casings or elements of identical cross-section which may or may not be circular, and which are of cylindrical shape with one end open, are so assembled that they fit hermetically in the same direction one inside the other over a limited depth to make up compartments, the last compartment being hermetically sealed from the exterior by an end, such elements being relatively thin and made from a material which is chemically and mechanically resistant to the products that the tanker may contain, and forming a core which is then covered with a covering layer of a glass-resin complex which consolidates it, the resultant assembly forming a mechanically homogeneous whole.
  • the cells, tubular casings or elements preferably have a curved end or a shape giving them a greater rigidity and, near the place where such end is connected to their side wall, have a recess terminating in a shoulder intended to fit perfectly against the inner edge of the side wall of the adjacent tubular casing or element, such recess and shoulder'forming a rebate.
  • tubular casings or elements have their end apertured, so that two adjacent compartments can communicate, the apertured ends thus constituting wave baffles.
  • the length of the tubular casings, elements orcells may vary to form compartments of different volumes.
  • the core is covered with a layer of a glassresin complex which may have a required shrinkage on drying, such shrinkage generally being accompanied by polymerization of the resin to hoop the core to prestress the tanker walls.
  • the wall has an excess thickness at the rebate and this reinforced place is chosen for anchoring the tanker, for example by means of a strap.
  • PK]. 1 is a side view of the tanker on a semi-trailer chassis; brokenlines being used to denote the compartments formed by the cells;
  • FIG. 2 is a cross-section of the tanker along the line A A of FIG. 1;
  • FIG. 3 is a detail in section showing the connection between twocells at the rebate
  • FIG. 4 is a partial section of the tanker showing its internal arrangement
  • HO. 5 is a detail in section of another embodiment of the arrangement of the cells.
  • the tanker is made up of cells, tubular casings or compartments 1 of cylindrical shape open at one end, all having the same crosssection, preferably having a rebate and differing if at all in respect of their depth, to make up tanker compartments of different volumes.
  • the closed end 2 of these elements 1 is generally curved. Some of these elements 1 may have an end formed with apertures 10, 11, so
  • the elements 1 may also have a manhole 9 and filling and emptying apertures. Near the place where the end 2 is connected to the wall of the cell or element 1, the wall has on the outside a recess 3 terminating in a shoulder 4. This recess 3 forms the rebate and is intended exactly to receive the edge 5 of the adjacent cell, so that the outer surfaces of the two cells do not project from one another and are perfectly flush.
  • the cells, tubular casings or elements 1 are either of metal or of a glass-resin complex, and their wall is thicker, particularly at the site of the rebate.
  • the elements 1 are interfitted in the required number and arrangement according tothe required tanker capacities and compartments, so that the edge of each element 1 is suitably located on the rebate of the next compartment, to which it is secured so as to be fluid-tight.
  • This is achieved by continuous gluing in the case of resin elements 1, or by a continuous weld in the case of metal elements 1.
  • the last element, which is open to the exterior, is closed by an end 7 of appropriate shape and of the same material, which is glued or welded thereto in the same way.
  • the outer edge of this end 7 preferably also has a rebate.
  • the system made up of the elements 1 and end after assembly forms a core which would not be strong enough for practical use of the tanker.
  • the core is then covered by a layer of a glass-resin complex consisting, for example, of wisps and threads ofglass coated with a polyester resin identical with that of the core.
  • a glass-resin complex consisting, for example, of wisps and threads ofglass coated with a polyester resin identical with that of the core.
  • the place where the ends 2 are connected to the outer wall of the tanker at the site of the rebate is thicker than the rest of the tanker and is more resistant to the radial stresses because of the presence of the ends 2.
  • This place is chosen as the location for straps 12 to anchor the tanker to the chassis 13 or any other mechanical component used for transportation or handling of the tanker.
  • the tanker will rest on a cradle shown diagrammatically at 14, at this place.
  • Low-level points are formed at the bottom of some of the compartments by deformation of the wall in order to facilitate complete emptying ofthe tanker.
  • the first production operation is to make cells or elements 1.
  • a mold of the required shape is externally lined with a glass-resin complex, and plugs corresponding to the manhole 9, emptying aperture, and the apertures and 11 in the ends 2 are fitted in the mold.
  • the mold is lined over the required length depending on the required width of the cell.
  • Appropriate conventional processes are applied in order exactly to form the recess 3 and shoulder 4 to make the rebate.
  • the edge 5 of the cell is exactly molded, so that it will fit exactly in the rebate ofthe adjacent element.
  • the utilized resin is a polyester resin and one utilizes a layer of glass at a proportion of about 50 percent of the total thickness.
  • the polyester is not saturated and catalysts and accelerators, as it is known, are added.
  • the second production operation consists of the polymerization, which is of a duration of several hours and is performed at first at ambient temperature and then terminated at about 80 C in a stove, in order to obtain a total reticulation.
  • the mold being smooth, one obtains cells or compartments 1 with an excellent interior surface, which could not be obtained, if the complex of resin is rolled directly over the mold serving as a core.
  • the third production operation in the case of resin elements 1 is to coat each rebate with an appropriate glue which is the same polyester resin used in the manufacture of the cells, which is catalyzed and accelerated and fit the cells one inside the other, and the end 7, to make up the tanker core, whose elements are exactly glued over a relatively large area to ensure sealing-tightness.
  • the last operation comprises coating exteriorly the core with a layer of glass fabric, filaments or fibers impregnated with the same polyester resin.
  • the coating is performed with constant tension and the proportion of glass is more important than before, namely about percent.
  • the polyester resin is catalyzed and its reticulation is obtained in a stove by heating to a superior temperature of about C.
  • This coating may be carried out with a machine on which the complete tanker rotates about its major axis, so as to wrap the glass-resin complex thereon. These machines are generally designed to make hollow bodies about a retractable core which is withdrawn when the body is complete.
  • the glass-resin complex covering will enclose the entire core and the walls of the tanker will be prestressed and have a greater strength.
  • the covering operation conventional steps are taken to provide the apertures, more particularly the manholes 9.
  • the total thickness of the walls of a tanker made in this way may be of the order of one centimeter.
  • each of the cells are equipped with a liner 15 preferably made of pure 100 percent resins, while the cells are preferably about 20 percent of glass fibers and 80 percent resins.
  • the outer member 8' is preferably made of about 20 percent resins and about 80 percent glass fibers.
  • the liner 15, if chosen of particular material permits the use of the tanker for food material or any other material.
  • the tankers according to the present invention are of a much lower cost price and weight. As compared with existing laminated resin tankers, the tankers according to the present invention are stronger and more rigid, more particularly because of the hooping effect provided by the outer covering; in particular, there is no danger of the internal partitions working themselves loose.
  • the junction points of the elements 1 which might tend to be weak are situated at the strongest places of the tanker: i.e., at the place where the partitions and wave baffles are situated. This type of construction avoids any reduction of the thickness of the edges of the elements 1. Also, the use of prefabricated cells makes the production much faster and more flexible for the production of tankers of various volumes on request.
  • tankers resin elements intended to contain foodstuffs can readily be annealed.
  • the inner coating of these tankers may be so selected as chemically to withstand the various substances they will contain and to have a surface condition suitable for the requirements of all food products.
  • these tankers can be made on machines for covering hollow bodies with a core remaining captive in the material.
  • a compartmented tank comprising a cylindrical outer member
  • each of said cells having a cylindrical portion and a convex end portion and engaging the inner face of said outer member along at least a part of the outer face of said'cylindrical portion of said cells, and said cylindrical portion of each of said cells having a peripheral'recess substantially at its line of junction with said convex end portion, and said recess being adapted to receive sealingly the cylindrical percent of glass fibers andabout 20 percent of resin.
