Definitions

  • the present invention refers to a sub-helix system with double spiral turns for use in horizontal volumetric presses with two horizontal subhelices in parallel.
  • the present invention finds its field of application in the manufacture of press machines commonly used in the sugar industry, increasing the performance of said presses, based on the optimization of the cleaning of the accumulated pulp that obstructs the filter surface preventing the water outlet, mixing and crushing of it, as well as a greater labyrinth effect of the path of the pulp as it passes through the press. That is, a geometric closure that prevents the recoil of the product when compressed.
  • the pressing performance of the depleted beet pulp in the aforementioned presses conditions the subsequent final thermal drying processes, with the consequent fuel savings.
  • this thermal drying is carried out in rotary dryers / ovens where the product is dried until it reaches around 90% of dry matter, then a final pressing in pellets is carried out, prior to its commercialization as feed for cattle .
  • the "pulp press propellers with double turns” contribute with respect to the state of the art in general and, particularly, with respect to the aforementioned invention of BABBINI & C SAS FLLI, a horizontal double helix press, where the propellers have a double pitch of turns of the same height, housed so that there is no collision between them and whose use contributes, in combination with the incorporation of a scraper / cleaner edge on the outer end of the turns that make up the propellers of the press, the following advantages or effects that result in an improvement in the total performance of the press;
  • A. Cleaning effect This effect is improved by the use of a cutting edge with appropriate geometry and which gives it a great scratching and cleaning capacity.
  • the effective edge length of the turns on the filter jacket is doubled. This implies that the cleaning of the perforation of the filter jacket that may be obstructed by the pulp during the pressing operation is doubled and that it is cleaned or uncovered when the propeller is scratched by scratching the accumulated pulp on the surface.
  • C. Crushed Effect The crushing and twisting capacity of the pulp fibers is greatly increased as there are more turns and closer to each other. This effect occurs in the central zone between the two propellers. In said area, between the spiral flanks of different propellers when rotating in the opposite direction very close to each other and when the product is trapped between said turns, squeezing, twisting and crushing of the pulp fibers very beneficial for water extraction occurs. inside.
  • D. Labyrinth effect The closing of roads through which the product can go back due to pressure differences during product compression is significantly enhanced. Thus, in the area located between the two propellers, the turns are so close that any movement of pulp between the turns or turns compartments is limited.
  • each sub-propeller is formed according to two turns or turns of turns of the same distance to the filter jacket, this being constant and being once mounted on the volumetric press, said distance between one and two millimeters to the filter or wrapping jacket It contains the pulp.
  • the spiral edge of both the first and second pass has an extension of the spire or scraper-cleaner as a hard recharge provided by abrasion-resistant welding and with a knife effect as it passes through the inside of the jacket filter, based on its termination forming an obtuse angle with the filter jacket itself, with a scratching-cleaning effect that forms the leading edge of all the turns of each of the two sub-propellers, on the face that carries out the compression on the pulp, maintaining a constant distance throughout its outer perimeter.
  • Figure 1 Main section of "Pulp press propellers with double turns”.
  • Figure 2. Main section of "Pulp press propellers with double spiral passage" inside a horizontal volumetric press with two horizontal subhelics in parallel.
  • each sub-propeller contains a second step or spiral edge (2) identical to the first step or spiral edge (1). That is to say, each sub-propeller is shaped according to two turns of turns (1, 2) introduced in a jacket (4) or longitudinal envelope, of equal constant distance in relation to the inside of the longitudinal shirt (4) itself, to position itself in its sweep on the inside of the filter jacket (4). Said minimum distance is between one and two millimeters.
  • the steps or edges of turns (1, 2) move the pulp (6) with the scraper-cleaner (5), cleaning accordingly the layer of pulp (6) that obstructs the drilled surface of the filtering jacket (4) and making a differentiation in its passage between a previous area of the filtering jacket (4) where water withdrawal is reduced (7) followed by a subsequent one where water extraction is high (8) .
  • the yields obtained in the same horizontal volumetric press with two horizontal propellers in parallel are compared by means of certified tests in a sugar bowl, using two single-step propellers, in relation to the use of the propellers subject to the present invention, evidencing an increase of dry matter between 2% and 2.5%.

Abstract

L'invention concerne des hélices de presse à pulpe à double pas de spires, pour leur utilisation dans des presses volumétriques horizontales à deux sous-hélices horizontales en parallèle introduites dans une chemise ou enveloppe longitudinale, communes dans l'industrie sucrière ; les sous-hélices présentant un double pas de spires de même distance jusqu'à la chemise filtrante, logées de façon à ne pas pouvoir entrer en collision et dont l'utilisation apporte, conjointement à l'incorporation d'un fil racleur-nettoyeur sur l'extrémité extérieure des spires qui forment les deux sous-hélices de la presse, une amélioration sensible de rendement de l'ensemble.
