Description

  The present invention relates to an absorbent sanitary product collection processing system, and more particularly to an absorbent sanitary product collection processing system used for processing a large amount of diapers, care pads, and the like.

  These types of disposable absorbent hygiene products have been used in everyday life and medical care since they have brought great convenience to people's lives since the invention of disposable absorbent hygiene products such as disposable diapers, care pads, sanitary napkins, etc. Widely used in applications.

  When an infant diaper is illustrated as an absorbent hygiene product, the layer in contact with the skin is generally a non-woven fabric and the outer layer is a polymer film (for example, a polyethylene film) as a waterproof layer, for the structure of an infant diaper. The contents are an absorbent layer made of fluff pulp and a water-absorbing polymer material (for example, sodium polyacrylate). After the diaper was used, feces were wrapped in the diaper, and the urine fluid was absorbed into the absorption layer. And the diaper containing feces and urine is thrown into the trash as it is.

  Disposable sanitary products are convenient, but used disposable sanitary products have a large volume, so that when they are consumed in large quantities, a large amount of garbage is generated. In addition, contaminants such as urine fluid, feces or blood remain in the used diaper and care pad, so that not only a strange odor is generated but also bacteria may propagate and cause environmental pollution. Therefore, in hospitals, nursing homes, nursing homes, postpartum care centers, etc., large amounts of used diapers, care pads, and other sanitary items are generated every day. You need to spend considerable costs to do that.

  Currently, most absorbent sanitary products are processed as they are by burying treatment or incineration in an incinerator, but are not suitable for burying treatment because the volume of used absorbent sanitary articles that have absorbed liquid is expanded. Furthermore, when the absorbent sanitary article is incinerated, energy consumption is large and corrosive gas is easily generated, which leads to the necessity of early maintenance of the incinerator and shortening of the incinerator life. For this reason, the waste of used absorbent hygiene articles becomes a serious problem of waste disposal and environmental protection.

  Moreover, in the prior art, various materials (for example, polymer film, non-woven fabric, fluff fiber, water-absorbing material) of used absorbent sanitary goods can be collected by pulverizing, precipitating, and separating. First, after the used absorbent sanitary goods are pulverized, various materials are obtained by precipitation and separation, and the collected materials are washed to remove contaminants. Therefore, during this process, various contaminants are lost to the crushed absorbent sanitary hygiene fragments and fiber materials, so the subsequent washing process is very difficult and the recovered material is clean enough. Rather, it cannot be reused, so such contaminated fibers can only be treated again by incineration.

  For the above reasons, there are considerable drawbacks to the existing absorbent hygiene product recovery and processing schemes. Therefore, how to overcome the above-mentioned drawbacks through the improvement of the processing method is one of the important problems to be solved by this field.

  The object of the present invention is to solve the drawbacks that current disposable absorbent article waste is difficult to process and materials cannot be recovered and reused.
