Definitions

  • the present invention relates to a sustainable process of separating, recovering, processing and purifying cellulose pulp contained in sanitary napkins and diapers for the purpose of obtaining pure cellulose pulp belonging to the chemical field. particularly related to personal hygiene products, in order to reuse the discarded material in the manufacture of absorbent and diapers, since the industrial applicability of cellulose in hygienic absorbents and diapers is extremely important and its very high cost necessitates strict control. and any loss in manufacturing system due to the high speed of the machines and process losses are considered major losses to the absorbent and diaper industry.
  • the present invention relates to a continuous and closed process for treating this residue.
  • plastic called scrap is separated from cellulose.
  • the gel is also separated at a specific stage of the process and both are treated as high quality raw materials that return to the diaper manufacturing process or to animal feces absorption mats as well as the manufacture of industry waterproofers. paints and others, including hospital absorbent mattresses, as a result of the innovation of this process. Because the process is continuous, a high rate of productivity, having industrial applicability and generating several economic advantages. Because the process is closed, another technology concern, the technical advantage of the present technology is that gel cellulose is produced from a recoverable waste and not from the pulp extraction and manufacture.
  • Another advantage that can be mentioned refers to the fact that it has production cost well below the cost of the conventional process, where the absorbent manufacturer buys and buys the virgin cellulose and also the gel. Both are introduced into the process to obtain the absorbent or diaper and the cost of these products is high relative to that of the patent in question.

  • the material (absorbent or diaper) is placed on a low speed (1) feed belt (1) that feeds an automatic continuous continuous knife sieve cutter (2) 2.5 "(inches), where the through material undergoes a cutting process, ie it is chopped into strips of size 10 to 15 mm;
  • Step 2 Separation and material displacement by following the following steps:
  • a cyclone system (5) consisting of at least four pulpers (51) is formed, formed by a tubular body (52) that tapers into the bottom forming a opening which is coupled to the duct (6) and is internally provided with a cyclone (53) of the same shape, which consists of perforated walls (54) with uniform holes and at the bottom is provided with an opening that is coupled to the duct (7).
  • the holes range from 10 to 15 mm in the first stage, 8 to 12 mm in the second and third stages and 6 to 10 mm in the fourth stage.
  • Step 3 Condensation, pressing and filtering, performing the following steps:
  • Step 4 Extraction and separation of the gel of the cellulose, according to the following steps:
  • the cellulose recovered from the diapers by the previous phases is centrifuged in a centrifuge (30), internally equipped with a 3mm opening cyclone (31), with a high radial speed of 20 m / 2, where the separation by centrifugal force pushes the cellulose out of the cyclone and simultaneously down where it is transported to exit, provided at the bottom of the centrifuge and driven to a cellulose condenser (32) and the gel with some cellulose is transferred by the fan (33 ) to a duct (34) leading it to another capacitor (35);
  • the cellulose separated in the previous step receives the same condensing and pressing treatment as in step 5, where it is conducted to the condenser (32), and after passing through the horizontal rotary mixer (321) it is gravity transported. for press (36) where the purified and processed cellulose bales which can be returned to the manufacture of diapers and absorbents are formed;
  • the product originating from this process is intended for the animal-care mat industries which use cellulose as an absorbent to receive pet urine and feces.
  • the pulp obtained in this process has a high percentage of gel in its composition, and this invention has the innovation of applying separation of the gel contained in the cellulose, further purifying the cellulose to obtain the high molecular weight gel (sodium polyacrylate) as a second resulting product.
  • the resulting product is a composition of Pe and pp plastics that are intended for plastics processing, recycling and extrusion companies.

Abstract

La présente demande de brevet d'invention concerne un procédé de séparation, de récupération, de traitement et de purification de pulpe de cellulose contenue dans les serviettes hygiéniques absorbantes et les couches à usage personnel, relevant du domaine de la chimie, et notamment des produits d'hygiène personnelle, avec pour objectif de réutiliser la matière jetée dans la fabrication de serviettes absorbantes et de couches. L'applicabilité industrielle de la cellulose dans les serviettes absorbantes et les couches hygiéniques revêt une importante considérable et son coût est très élevé. Il est donc nécessaire d'exercer un contrôle rigoureux, toutes les pertes subies dans le système de fabrication du fait de la haute vitesse des machines, de même que les pertes en cours de processus, étant considérées comme très dommageables à l'industrie des serviettes absorbantes. Le procédé comprend trois étapes : Premièrement, la préparation et le déplacement de la matière ; deuxièmement, la séparation de la cellulose et du plastique ; et troisièmement, la condensation, le pressage et le filtrage. Dans le cas des couches, la troisième étape est remplacée par une quatrième étape d'extraction du gel et de séparation de la cellulose.
