Definitions

  • PROCESSING DRUM FOR TREATING I-llDES Inventors: Manuel Portavella Casanova;
  • the present invention relates to drums for hidetreatment processes in which the hide loading and unloading operations are effected automatically by simple reversal of the direction of rotation, introducing or removing them from the radial apertures directed in the same direction though diametrically opposing each other and located at the ends of two rectangular section ducts close to each other and fitting over more than 180 of the outside of the drum cylindrical face, communicating by the other end in the form of a bend with the inside of the drum. Connections also located diametrically opposite each other.
  • a. Tubs These are semi-cylindrical tanks located horizontally, open at the top by way of a rectangular face. These tanks are fixed and secured to the floor. They are generally the product of lined civil engineering work, wood and less frequently polyester or other materials. Loading. and unloading is generally effected through the open top of the tank. It is an arduous and troublesome operation.
  • Drums These are cylindrical containers with one or several doors in the curved face and rotating about their geometrical axis, generally being made of wood, though an increasing number is being made at present in polyester.
  • the liquids are fed in through holes perforated around the drum. Discharge is effected through the side-doors, as well as the loading of the hides. This operation is largely arduous and troublesome.
  • Rotors These are extended blade wheels rotating at the surface of the open face of the tubs cited above. The blades are half-submerged within the liquid/hides mass, and on rotating, promote the movement of the said mass within the tub.
  • Vanes and blades These are cylindrical rods or curved and polished profile blades, integral and distributed on the internal face of the curved wall of the drums cited above, and which on rotating the drums, ensure the movement of the contents. If the internal cylindrical and smooth part of the drum lacked such vanes or blades, the stirring movement as produced by rotation, would be very limited and quite insufficient to ensure a homogeneous solution and to unfold the hides within the process liquid.
  • CONTAINER Clearly this is not a mill-type arrangement, nor can it be classified as a drum in the normally accepted sense of the word, since the internal form is cylindrical, excepting that it has two large curved spiral-like ducts of rectangular cross section fitted to the cylindrical part, thus increasing the capacity of the central cylindrical compartment by 20 percent each.
  • This stirring motion can be compared with a transverse ducting transporting the liquid mass from one compartment to another.
  • FIG. 6 shows a transverse section through the vertical plane indicated in Vl-VI of FIG. 2.
  • the relevant drum is made entirely in polyester to take advantage of its impermeability and the fine surface finish which can be achieved.
  • the drum consists of a cylinder (1), two truncated cone perforated partitions (4, an end wall with the fluids inlet (2), another end wall with the fluids discharge (3) and two spiral-like ducts of rectangular cross section located at the center of the cylinder (1) and wound over more than l80 of the outer face of the cylinder.
  • the spiral-like ducts (6, 7) have radial apertures running in the same direction, though diametrically in opposing positions, as well as the connections curving into the inside of the drum.
  • the outline of one of the connections can be seen in FIG. 5 with reference to component (7).
  • Accesses (8, 9, 10, 11) are provided to all internal compartments of the drum. The purposes of such accesses are to allow inspection, maintenance, and cleaning of each compartment.
  • the compartments and their related accesses are:
  • An external recirculation circuit (19) shown in FIG. 1 is located on the outside of the drum, communicating with the drum at the fluid outlet (13) and with the fluid inlet (12).
  • the movement is a rotary movement on the geometrical axis of the cylinder (1) in the horizontal position, drivenby a unit shown in FIG. 1 equally allowing reverse rotation.
  • Recirculation This is effected by way of the eccentric container (18) which, as the drum revolves in a suitable direction and when passing through the lower part of the fluid, fills up by way of the loading aperture (14), raising its contents above the central axis and forcing the fluid to discharge by gravity through the duct (13), thus commencing the circulation in the outer recirculation circuit (19), the fluid finally returning by way of the opposing part of the drum, or by way of the inlet duct (12).
  • the cycle is repeated with each striguion of the drum, thus ensuring automatic recirculation of the fluid within the drum.
  • the said fluid in the external circuit passes through the additional equipment (not detailed herein), allowing complete control of the chemical properties of the solution, controlled adjustment of pH, addition of products, temperature control etc. ,etc. ,thus allowing the solution to be maintained in the required conditions throughout the whole of the process.
