Definitions

  • the subject of the invention is an installation for the preparation of starch adhesives intended for the industry, in particular the paper industry, and more particularly for the manufacture of corrugated cardboard.
  • the starch is used dry in the form of a commercial powder, delivered by pneumatic means at the level of the stirring means, that is to say within the adhesive in preparation.
  • starch is meant, throughout the text, native starches from all sources (wheat, but, but waxy, but with a high amylose content, potato, cassava and others) as well as the corresponding modified starches which can be obtained. in particular by physical or chemical modification of native starch.
  • the drawback of the installations in question lies in the fact that at a height of the piping (parallel to the axis of the enclosure) which corresponds to the final level of the glue contained in the latter, there occurs after a few manufacturing cycles, a deposit on the inner wall of the pipe as a result of glue rising, deposit which results in an internal shrinkage thereof; such a narrowing of the section of the piping causes a pressure drop in the powder starch supply circuit and causes an increasing lengthening of the starch introduction times.
  • the object of the invention is, above all, to remedy this drawback and to provide an installation of the kind in question which responds better than those which already exist to the various wishes of the practice and in which, in particular, is eliminated or at least largely spaced the need for cleaning of the powdery starch supply piping.
  • the Applicant Company has the merit of having been able to determine that this goal could be achieved as soon as the starch supply pipe, conveyed by pneumatic means, crosses the wall of the enclosure from the outside and towards the inside thereof at a level close to the lower part of the enclosure, adjacent to the stirring means arranged inside the latter.
  • the installation according to the invention for the preparation, preferably discontinuously, of starch adhesives in particular for the manufacture of corrugated cardboard and which essentially comprises a chamber of substantially vertical axis equipped with means of agitation acting at a lower level of the enclosure as well as of means for feeding the latter with all the constituents of the adhesive to be produced and in particular of starch used vre in the dry state in the form of powder conveyed by pneumatic means, is characterized in that the means for supplying the enclosure with powdery starch comprise a pipe by which the starch arrives and which passes through the wall of the 'enclosure from the outside to the inside thereof at a level close to the lower part of the enclosure and adjacent to the stirring means formed by the latter.
  • the powder starch supply piping comprises a part substantially parallel to the axis of the enclosure and situated outside thereof, this part extending from a level located above the highest level that the glue can reach in the enclosure up to a substantially horizontal end portion, crossing the wall of the enclosure from the outside towards the inside and emerging at a level close to the stirring means, preferably tangentially to the circle described by the ends thereof, said piping comprising, according to an advantageous embodiment of the invention, as close as possible to the enclosure but outside the latter , means for opening and closing the passage of starch.
  • Proposing therefore, to establish, according to the invention, an installation of the kind in question, it is done as follows or in a similar manner.
  • This installation is made to consist essentially of an enclosure with a substantially vertical axis XY, and generally designated by 1.
  • the enclosure 1 comprises, as known, stirring means, for example a turbine 2, held in the vicinity of the bottom 3 of the enclosure by a shaft 4, substantially parallel to the axis XY and being able to be driven in rotation by drive means 5.
  • stirring means for example a turbine 2
  • a shaft 4 substantially parallel to the axis XY and being able to be driven in rotation by drive means 5.
  • the starch is introduced by a pipe generally designated at 12, arranged outside the tank and on which are mounted pneumatic means not shown, for example, a device of the booster type, under the influence of which the powdery starch is conveyed to the enclosure.
  • the piping 12 crosses the wall of the enclosure 1 and penetrates inside the latter at a level located in the lower part thereof and close to the level at which the turbine 2 is located. , i.e. near the bottom 3.
  • the end 12a of the pipe 12 opens tangentially to the circumference C described by the turbine, as shown in FIGS. 1 and 2.
  • the last part of the piping 12, through the which it penetrates inside, is advantageously constituted as shown by a horizontal element 12b and it follows a substantially vertical part 12c which itself is connected at a level higher than that which the glue can reach. inside the enclosure (to avoid any accidental rise of the adhesive to the booster device), to a part 12d which connects the assembly to the starch tank not shown and which comprises the means of overpressure not shown.
  • the pipe 12 comprises means for opening and closing the passage of the starch generally shown at 13 and which are arranged as close as possible and, preferably, outside the enclosure 1 ; in the embodiment illustrated in Figure 1, they are arranged on the part 12b.
  • opening and closing means 13 are advantageously constituted by a motorized isolation valve, for example of the ball valve type.
  • an elastic element 14 consisting, for example, of a tubing element made of elastomer, allowing these movements.
  • a nozzle 15 comprising closing means 16 and authorizing, in the open position of said means 16 and of the valve 13, to sweep the part 12b.
  • Installations of this type are intended to work with charges comprising several hundred kg of starch and several thousand liters of water.
  • the precision achieved is easily of the order of 1 '.
  • the measurement of the quantities of sodium hydroxide, borax and possibly of resin introduced, quantities which are of the order of a few kg or a few tens of kg, is preferably carried out using volumetric metering devices.
  • the device for introducing powdery starch is actuated twice according to the sequence indicated above.
  • starch adhesives prepared in accordance with the present invention can be used in all industries where starch-based adhesives are commonly used.
