Definitions

  • My invention relates to an apparatus and a method utilized in the manutactureo't paper dough.
  • the present invention has for an object a boiler arrangement with an interior hearth for transforming vegetable matter into paper dough by oxidation with ozone and lixiviation by means of thevegetable matter cin ders.”
  • This arrangement has the advantage of eliminating the numerous'pieces of appa-' ratus heretofore mentionedas well as the manual labor connected therewith.
  • the accompanying drawing shows a perspective view otmy apparatus with parts broken away to show the interior.
  • My apparatus comprises a casing-0t sheet steel A.
  • Said casing forms in eltect a sort of boiler and is provided on the interior with afirebox C formed of a sheet metal member'H and a. header I L, The remainingportion of the interior of said casing A provides a steam and water space B.
  • Firetubes Hare connected tosaid header and. communicate with a stack 0 provided with a damper O passing throughfithe steam and water space B.
  • an outlet D provided with a valve D for allowing the residuary lixiviumsgiven off by the G only part of which is shown.
  • a valve D for allowing the residuary lixiviumsgiven off by the G only part of which is shown.
  • the fire box is provided with a door R for obtaining access thereto and inj ectors P -tor projecting the residuary-water 0f the heating process by atomization.
  • the water is transformed intostcam and escapesby stack 0 thereby accelerating "the draft therein.
  • the solid material decomposed from the vegetable matter such as 'vasculose, pectose and the like is calcinated' and transformed into cinders and becomes added tothose of the hearth.
  • Thepotash is likewise recovered andis mixed with the cinders for the preparation of other lixiviums.
  • lhe basket B is firstfilled with vegetable matter previously cut into small pieces and then introduced into the space B of easing A.
  • Door F is then sealed hern'ietically by means of its-pressure screws F and water is introduced into th'e's'pace B through the inlet pipe N until the vegetablematter to be treat- 1,710,325 PATENT OFFICE.
  • Previously ozonized air of a suitable'fconcentration is then introduced into the space B at a pressure of from 3 to 4 atmospheres for a periodof about two hours according to the character oft-he'vegetable matter being treated and the degree of oxidization desired,
  • the ozone is then evacuated from the space B after which it is filled with a lixivium oil potassium previously prepared to the proper degrees Baume according to the vegetable matter under treatment and the paste to be obtained by lixiviation oit the c inders of the vegetable matter after having served as a combustible.
  • the carbonate o l-Y potassium thus obtained will be subsequently icaustified when quicklime is added in suitable proportions which is obtained as previously mentioned .by dehydrating limestone in the the box C during roasting of :the vegetable matter.
  • the fire is then lighted in the firebox and the pressure in space E is then gradually brought up to from 3 to 8 kilograms which pressure is held during-the time necessary to treat the vegetable matter and obtain the quality of paste desired.
  • the space 13 is again. filled with ordinary water for washing and cooling the paste obtained.
  • the space I) is filled with a suitable bleaching agent under pressure, such as, chlorine, ozone, hypoclrlorite-or the like, after which, if the agent used is of a gaseous nature it is allowed toescape through escape valve L, or by running :water through the space E by means of inlet N and outlet D it the agent isof a liquid nature.
  • the paste thus obtained is suitable for the manufacture of wrapping paper, printing paper or even papero fthe finer grades which is formed into sheets by any otthe processes known in the art.
  • the injector P may be .operated for recovering the residuany lixiviums .of the different operations described. Also during said heating operation limestone i'or dehydration is introduced into the firebox (l by means of the door R, which lime is used for the purpose above mentioned.
  • va ,paper paste from vegetable substances, which comprises, soa ing a quanti y o veg tabl matter i water, withdrawing said water, treating said vegetable matter with ozone, subsequently treating said vegetable matter with a lixivium of potassium, adding quickliine to the said vegetable matter, heating said vegetable matter and allowingit .to be subjected to pressure and washing and bleaching the'paste thus formed, said lixivium of potassium being prepared from the ashes of the combustible used in heating said'vegetable matter.
  • the method of obtaining a paper paste from vegetable substances which comprises, soaking a quantity of vegetable matter in water, ithdrawing said water, treating said vegetable matter with ozone, subsequently treating said vegetable matter with a liXivium of potassium, adding .quickline to the said vegetable matter, heating said vegetable matter and allowing it to be subjected .to the pressure generated thereby and washing and bleaching the paste thus obtained, said 1iXi-' vium'oit potassium being prepared from the ashes of the combustible used in heating said vegetable matter and said quickli-me being obtained by dehydrating limestonesby said combustible.
  • the method of obtaining a'paper paste from vegetable substances which comprises, soaking a quantity of vegetable matter in water, witlidrawingsaid water, treating said vegetable matter with ozone, subsequently treating said vegetable matter with a lixivium of potassium, adding iquicklime to the said vegetable matter, heating said vegetable mat ter and allowing it to be subjected .to :the pressure generated thereby, washing the paste'thus obtained,:bl-eaching said paste, said lixivium of potassium being prepared from the ashes of the combustible used in heating said vegetable matter and recovering the residuary lixiviums 01 the combustible by evaporation and calcination.
  • An apparatus for obtaining paper paste comprising in combination, a casing, a firebox in said casing, firetubes associated with said firebox, a steam and Water space surrounding said firebox and said firetubes, an inlet pipe "for said steam and water space, an outlet pipe for said steam and water space, a steam dome associated with said steam and Water space,
  • a steam exhaust connected to said steamdome, a hermetically sealed door for said steam and water space and means for introducing vegetable matter for treatment into said steam and Water space for the purpose described.
  • said means comprises a wire basket mounted on rollers sliding on rails provided in said steam and Water space.
  • said firebox is provided with a grate, a shaker beneath said grate and a seive beneath said shaker for recovering the cinders of said
