Definitions

  • ABSTRACT A tank for the continuous treatment of elongated metal strips and workpieces by transient immersion in acid solutions comprises an elongated tubular construction having circumferentially extending tubular stiffening parts at spaced positions along its length, the wall of the tubular construction being formed with ports opening into the interior of said stiffening parts and said interiors of all of said stiffening parts being connected to a manifold for fume extraction purposes.
  • This invention relates to tanks for the continuous treatment of elongated metal strips and workpieces and is particularly concerned with the continuous treatment of ferrous and non-ferrous metals by transient ir'nmersion in acid solutions.
  • Currently available tanks are normally open topped metal structures, usually lined with chemically resistant rubber or synthetic resin material and protected by internal brickwork. Loose covers are provided and rest on top of the tanks to reduce the emission of fumes and heat from the tanks.
  • Such tanks have the disadvantage that they must normally be built in situ and when a tank on an existing treatment line has to be replaced the result is that the line is out of use for a protracted period.
  • the loose covers used do not provide an efiicient fume seal and powerful fume extraction equipment is often required. This has the effect of cooling the acid in the tanks and extra heat has to be continuously supplied.
  • a tank in accordance with the invention comprises an elongated tubular construction having circumferentially extending tubular stiffening parts at spaced positions along its length, the wall of the tubular construction being formed with ports opening into the interior of said stiffening parts and said interiors of all of said stiffening parts being connected to a manifold for fume extraction purposes.
  • FIG. 1 is a section on one end of the treatment tank
  • FIG. 2 is a section on line 22 in FIG. 1 and FIG. 3 is a cross-sectional and view of a further embodiment of the invention.
  • the tank is an elongated tubular construction having a cylindrical centre section and a pair of end sections similar to that shown in FIG. 1.
  • the tank may conveniently be formed of a glass reinforced synthetic resin material in a single piece or several sections may be joined together to make up the tank. Alternatively other materials may be used.
  • the tubular section of the tank is supported by a pair of continuous hollow leg sections one of which is used as a manifold for fume extraction purposes. Extending circumferentially around the tubular tank area series of tubular reinforcing parts 1 1 which have ports 12 into the interior of the tank. These tubular reinforcing parts 1 1 each terminate at one end in the manifold 10.
  • a flanged connecting spigot 13 is provided at one end of the manifold 10 for connecting the tank to the fume extraction system.
  • the tanks described can be made off site and transported to the treatment line when required. Installation of a preformed tank in this way is a relatively simple matter and it is envisaged that the down-time on a line where a spare unit has to be installed could be a matter of hours rather than weeks. Any subsequent rubber or plastic lining with brick protection would be very light and substantially easier and cheaper to apply. The lining process would be more likely to be effectively carried out in view of the smooth internal surface of the tank.
  • the tanks can be produced very inexpensively as compared with existing tanks and this makes it economically feasible for a user to carry a spare tank in stock.
  • the tank is reinforced longitudinally by the legs 10 and circumferentailly by a reinforcing tubes 11 which form an extremely rigid structure which can therefore be made very light. Considerable savings in foundation and support costs of the tanks can therefore be achieved and on-site installation times can be reduced considerably.
  • FIG. 3 there is shown a further elongated tubular tank 14 of cylindrical section.
  • This tank 14 may also conveniently be formed of a glass reinforced synthetic resin material in a single piece or several sections joined together.
  • the tank 14 is supported by a pair of hollow leg sections 15 which need not however be continuous.
  • Extending circumferentially around the tubular tank are a series of tubular reinforcing parts 16 which have ports into the interior of the tank. These tubular reinforcing parts 16 each terminate at one end in a manifold 17 of cylindrical section.
  • a tank comprising an elongated tubular construction having circumferentially extending tubular stiffening parts at spaced positions along its length, the wall of the tubular construction being formed with ports opening into the interior of said stiffening parts and said interiors of all of said stiffening parts being connected to a manifold for fume extraction purposes.
