Abstract
The invention relates to the technical field of reclaimable resource recovery and utilization, and discloses a recovering and treating method for discarded disposable sanitary products. The method comprises the following steps that: (1) discarded disposable sanitary products are crushed and separated; plastic materials in the discarded disposable sanitary products are delivered to a collecting chamber through an upper port on a crushing and separating machine; super-absorbent materials and cotton fabrics in the discarded disposable sanitary products are delivered to a separating tower through a lower port on the crushing and separating machine; (2) with the controlling upon the air delivery, according to the principle of gravity difference between the super-absorbent materials and the cotton fabrics, the super-absorbent materials and the cotton fabrics are separated in the separating tower; the super-absorbent materials are discharged from a lower port of the separating tower, and the cotton fabrics are delivered to a cotton fiber settling chamber.
Description
Technical field
The present invention relates generally to the utilization of the recycling of renewable resources technical field, is specifically related to scrap the recovery and treatment method of disposable sanitary articles, especially has the disposable sanitary articles of scrapping of plastic components, as the recycling of paper nappy, sanitary napkin etc.
Background technology
Application and popularization along with disposable sanitary articles, the consumption of disposable sanitary articles all significantly increases every year, the waster of Chan Shenging generally is directly proportional with output in process of production, for sanitary paper product and personal hygiene article, the waster rate of production equipment is about 2% at present, and this does not also comprise owing to the substandard products that connect material and the glue power traction rises.According to incompletely statistics, about 5,000 hundred million of the disposable sanitary articles of global annual production and sales at present (comprising that the adult uses), and the defective scrap that produces of process of factory production and corner etc. also are that quantity is surprising, and only China's Mainland disposable sanitary articles and sanitary napkin manufacturing enterprise just produce scrap and the leftover pieces more than 20000 tons every year.
Present domestic recycling technical elements at disposable sanitary articles and sanitary napkin, it almost still is blank out, usually all be the mode of burning and landfill, scrap and leftover pieces are in the simple and crude individual workship of some conditions, and separating technology is simply equipped, and recovery utilization rate is low, the operation site surrounding is abominable, this mode not only forms environment to be polluted, and also can cause the serious waste of resource, reduces the use value of these waste and old materials.
Summary of the invention
In order to address the above problem, the invention provides a kind of rate of recovery height, the disposable sanitary articles recovery and treatment method of scrapping free from environmental pollution.
The present invention is achieved in that
A kind of recovery and treatment method of scrapping disposable sanitary articles may further comprise the steps:
(1) will scrap disposable sanitary articles and carry out broken apartly, and scrap plastic material in the disposable sanitary articles from the plastics collecting bin that enters suitable for reading of millerator, high-absorbent material and cotton fiber material are delivered to knockout tower by blower fan from the end opening of millerator;
(2) by control to air quantity, in knockout tower, utilize the gravitational difference principle of high-absorbent material and cotton fiber material, high-absorbent material is separated with cotton fiber material, and high-absorbent material is discharged from the knockout tower end opening, and cotton fiber material is delivered to cotton fine expansion chamber from knockout tower by blower fan.
Preferably, the described blower fan angle of carrying cotton fiber material and high-absorbent material to enter knockout tower is 90 degree.
Preferably, described cotton fiber material and the time of high-absorbent material in knockout tower are 15～20 seconds.
The present invention can do further improvement: in (1) separating step, in the middle of millerator screen cloth is set, prevents that plastic material from entering end opening.
The present invention can also do further improvement: in (2) separating step, screen cloth is set in the middle of the knockout tower and rotation is swept.
The recovery and treatment method of scrapping disposable sanitary articles provided by the invention adopts the dry process method, has the following advantages:
1, the method that adopts dry method to separate does not adopt water in the whole recovery separation process, has reduced the consumption and the pollution of water resource, has realized the unification of resource regeneration and environmental protection;
2, can each material to separate completely in the disposable sanitary articles with scrapping, the effect of separation can reach more than 90%, and each material yield rate height, can reach more than 99.5%, high-absorbent material is all reclaimed, and can not enter in the environment, reduces not salvage material to the pollution of environment;
3, separate removal process mechanization, controllability is strong on the one hand, is convenient to unified standard, is suitable for scale on the other hand and reclaims, and lean on artificial cotton fiber material and the plastic material of separating in the prior art fully.
The specific embodiment
The recovery and treatment method of scrapping disposable sanitary articles that present embodiment provides may further comprise the steps:
The disposable sanitary articles (paper nappy, sanitary napkin) of scrapping that (1) will be recovered to carries out broken apart, scrap plastic material in the disposable sanitary articles from the plastics collecting bin that enters suitable for reading of millerator, high-absorbent material and cotton fiber material are delivered to knockout tower by blower fan from the end opening of millerator;
(2) by control to air quantity, in knockout tower, utilize the gravitational difference principle of high-absorbent material and cotton fiber material, high-absorbent material is separated with cotton fiber material, and high-absorbent material is discharged from the knockout tower end opening, and cotton fiber material is delivered to cotton fine expansion chamber from knockout tower by blower fan.
In the present embodiment, the angle that blower fan carries cotton fiber material and high-absorbent material to enter knockout tower is preferably 90 degree, this angle can further improve the rate of recovery of cotton fiber material and high-absorbent material,, not thorough with what avoid next step cotton fiber material to separate with high-absorbent material for next step cotton fiber material and separating of high-absorbent material doing better preparation yet.
In order further to improve the separation rate of cotton fiber material and high-absorbent material, preferred cotton fiber material and the time of high-absorbent material in knockout tower are 15～20 seconds among the present invention, the cotton fiber material and the time of staying of high-absorbent material in knockout tower are appropriate, be more conducive to the separation of the two, if the time is oversize also to be a kind of waste of the energy, operating efficiency is also low, so preferred 15～20 seconds time in this method.
In addition, enter end opening, can also in first step separation process, in the middle of millerator, screen cloth be set in this method, prevent that plastic material from entering end opening for fear of plastic material.
Equally, in (2) separating step, can screen cloth be set in the middle of the knockout tower and rotation is swept, strengthen the effect of separating.
More than the technical scheme that the embodiment of the invention provided is described in detail, used specific case herein the principle and the embodiment of the embodiment of the invention are set forth, the explanation of above embodiment only is applicable to the principle that helps to understand the embodiment of the invention; Simultaneously, for one of ordinary skill in the art, according to the embodiment of the invention, the part that on the specific embodiment and range of application, all can change, in sum, this description should not be construed as limitation of the present invention.
