Definitions

  • the invention relates to a tumbling drum, tanning and dyeing.
  • Each barrel is powered by three separate circuits: the air circuit, which we circulates inside the barrel, the circuit of additional chemicals, which contribute to improving the skimming operation of skins, and the water circuit, which helps maintain the proper moisture level inside the barrel itself.
  • a barrel is essentially constituted by a cylindrical steel container, a diameter of about two meters, which rotates on its axis arranged horizontally and is equipped with a hatch for the introduction and unloading of skins.
  • a disadvantage that manifests itself in the use of barrels is in the fact that, in the zone of support of the blades on the inner wall of the barrel, it is formed re-entrant angles where the products of work are deposited, which makes their elimination difficult.
  • the object of the invention is to make a barrel in which the dirt can be totally eliminated at the end of each job, so as to avoid the possibility of seeing the material being worked stained by the residues of the previous work.
  • this is achieved by inserting, between the blade and the bearing surface of this on the inner wall of the barrel, fittings that fill said angles and interstices, so as to connect them, giving them a profile curvilinear.
  • a primary or base liner is applied. practically flat and having a width greater than the width of the base of the blade, in order that the salient parts, suitably rounded, come to fill the two linear angles, rounding them.
  • barrel 1 is constituted by a body cylinder comprising a cylindrical wall liner 2, between the two flat side walls 3, or cheeks.
  • blades 4 which protrude radially on the cylindrical wall 2 and are of pentagonal section.
  • each blade a base liner 5 and two head lining 6 are respectively applied in the zone of contact with the circular wall 2 and with the two flat lateral walls 3.
  • the base trim is constituted by a lamellar body 7 compressed between the foot 8 of the blade 4 and the cylindrical wall 2, and which protrudes laterally by two profiled portions 9 which act as a coupling longitudinal base between the wall 10 of the blade and said cylindrical wall, eliminating in this way the acute angle defined by these last.
  • the head gasket 6 is constituted by a cap 11, threaded on the end 12 of the blade and compressed between the latter and the side wall 3.
  • the cap 11 is provided with a protrusion profile 13 which acts as a head connection between the wall 10 of the blade and the wall 3 and eliminates the acute angle defined by them.
  • the profile of the profiled projection 13, which follows the profile of the blade, has a base 14 slightly enlarged to enlarge the surface of connection and which is provided with housings 15 for receiving the end of the filling basic 5.
  • a rib 16 of the cap 11 made of preferably plastic material such as the base liner 5, to the right of the screws 17 of blocking of the blade on the wall 3 are inserted spacer metal washers 18, which, having a thickness slightly less than the thickness of said rib, allow a regular closure, metal against metal.
