[0009]
In the present invention, the term dirty sanitary ware means sanitary ware that has been soiled during the manufacturing process, transportation process, and display process of sanitary ware, as well as sanitary ware that has been used and soiled, that is, used sanitary ware. In the present invention, the term pulverization means crushing, coarse crushing, intermediate crushing, crushing and cutting.
In the present invention, a dirty sanitary article is a dirty paper diaper, a dirty milk pad, a dirty urine pad, a dirty sheet, a dirty gauze, a dirty bandage or a dirty absorbent cotton, or a combination of two or more dirty hygiene articles. As well as dirty paper diapers, used milk pads, used urine pads, used sheets, used gauze, used bandages or used absorbent cotton or a set of two or more used sanitary products. In the present invention, a sanitary article to which dirt is attached is, in particular, a used paper diaper.
[0010]
Sanitary goods, especially sanitary goods such as paper diapers and absorbent pads, have a water-absorbing layer made of pulp and superabsorbent resin placed between the layers of water-absorbing paper, and the bottom of the water-absorbing paper layer at the bottom A water-impermeable plastic material film is provided at the upper side, and a water-permeable plastic material non-woven fabric is provided above the upper absorbent paper layer. In the case of used hygiene products, for example, used paper diapers, dirt such as stool and feces due to excretion adheres mainly to a part of the nonwoven fabric made of plastic material, and dirt caused by body fluids such as urine is made of plastic material. It adheres to a part of a nonwoven fabric, a water absorbing layer, and a plastic material film. In the case of a used urine pad or milk pad, dirt due to body fluids such as sweat and urine adheres mainly to a part of the nonwoven fabric made of plastic material, a part of the water-absorbing layer, and a part of the plastic material film.
[0011]
Also in the present invention, soiled sanitary products are washed with water or water containing a disinfectant, for example by contact with a disinfectant solution or disinfectant suspension or with water or water containing a disinfectant. By spraying or spraying water or water containing a disinfectant on the sanitary product, a part of the dirt adhering to the sanitary product is separated. In particular, in a sanitary product treated with water containing a disinfectant, part of the soil is separated from the sanitary product, and the adhering microorganisms are disinfected or disinfected by getting wet with the water containing the disinfectant. In the present invention, sanitary goods are immersed in water or water containing a disinfectant, and the water containing the disinfectant is agitated with a stirrer or the like to destroy the plastic film and the nonwoven fabric of the exterior part of the sanitary goods. It is possible to remove a part of the dirt adhering to the sanitary product without any trouble. In particular, when water containing a disinfectant is used, the sanitary product can be disinfected and a part of the dirt adhering to the sanitary product can be removed. In this case, it is preferable to provide the stirring blade in a side space or a bottom space partitioned by a perforated plate or the like so that the sanitary article does not contact the stirring blade.
[0012]
When using water containing a disinfectant, it is preferred to immerse the sanitary article in water containing the disinfectant. In this case, sanitary products immersed in water containing a disinfectant, such as disposable diapers, are unwrapped by the flow of water containing the disinfectant by stirring or disturbance, and solids such as feces are sanitized. Apart from the product, it is separated from the cleaning space, for example through a perforated plate provided at the bottom. In the present invention, water-soluble dirt such as urine and body fluid adhering to sanitary goods is dissolved and separated in water containing a disinfectant, but solid dirt such as feces is separated from sanitary goods, Most of them are finely dispersed and dispersed in the solution. The sanitary materials are cleaned and sterilized by stirring in water containing disinfectant, including the separated dirt.
In the present invention, when the water containing the disinfectant is agitated or disturbed, at least a part of the pulp and the superabsorbent resin of the contents of the sanitary product immersed in the water containing the disinfectant is unraveled and biased. Water-soluble dirt such as urine and sewage adhering to the contents can be separated from sanitary goods. The sanitary product wetted with water containing the disinfectant that has been dissolved is collected on the bottom perforated plate without being crushed, scraped by a scraping device or the like, discharged, and sent to a pulverizer.
[0013]
For example, in the case of used paper diaper waste, the dirt separated from sanitary products is mainly sewage such as feces or urine, and is separated by sieving with a porous material such as a coarse mesh or a perforated plate. For example, it is separated from waste paper diaper waste. When the water containing the disinfectant is used, the separated waste is moved with the disinfectant-containing water to be disinfected and sent to the subsequent activated carbon treatment process or the treatment process by the activated sludge method. To be processed. In the case of water containing a disinfectant during these purification treatments, in order to reduce the disinfecting action remaining in the disinfectant-containing water, the disinfectant is decomposed by dilution with water, neutralization, or standing. Preferably it is done.
[0014]
The sanitary ware, in which a part of the dirt is separated and scraped by the scraper, is sent to the grinder and crushed. In the present invention, the term pulverization means cutting, crushing, coarse crushing, intermediate crushing and crushing, and the crusher is a crushing machine, crushing machine, crushing machine, middle crushing machine, breaking machine or cutting machine. It can be. In the present invention, a pulper can be used as such a pulverizer. According to Pulper, in the sanitary goods, the non-woven fabric and the plastic film of the exterior part are broken, and the contents including the pulp and the superabsorbent resin are drawn out and pulverized by the turbulent flow of water containing the disinfectant.
The sanitary product pulverized particles crushed, cut or pulverized by a pulverizer include particles with much dirt, particles with little dirt, and particles without dirt at all. As a result, it is possible to increase the unit separation degree of particles that are not soiled at all.
[0015]
Moreover, in this invention, at the time of a grinding | pulverization, the grind | pulverized sanitary goods ground material can be processed into the water which contains the water under stirring or disinfectant, and can be made into the raw material which comprises sanitary goods. Most of the water-soluble stains adhering to the material are dissolved in water containing a disinfectant and separated from the material, and solid matter such as feces remaining without being separated in the step before the pulverization step is Due to the stirring action of the stirring member and the disturbing action of the disinfectant solution, most of it can be separated and washed away from the material.
[0016]
In the present invention, a sanitary product to which dirt adheres is first partly separated and then wet crushed. In this way, when part of the dirt is separated prior to pulverization, most of the dirt can be separated from the sanitary goods without being crushed. Therefore, it is preferable because the separation process can be simplified. In the present invention, the sanitary product is pulverized and pulverized in the pulverization process by the rotor blades of the pulverizer, the contents are drawn out by the turbulent flow of water containing the disinfectant. Because it is crushed, sanitary products from which at least some of the dirt has been separated are strongly unwound by crushing, and dirt that adheres to sanitary goods without being separated in the previous washing process is decomposed into raw materials In the process, the material of the sanitary product dispersed or dissolved and decomposed can be strongly disturbed and sufficiently brought into contact with water containing a disinfectant, which is preferable for separating dirt.
[0017]
Further, in the present invention, it is preferable to grind dirty sanitary products in water containing a disinfectant, but crush sanitary products wet or wet with water or water containing a disinfectant. You can also. In this case, if the sanitary sanitary product is wetted in contact with water containing a disinfectant or in contact with the turbulent flow in water containing a disinfectant prior to crushing, the crushing is performed during crushing. This is preferable because scattering of objects can be prevented.
[0018]
In the present invention, the water-soluble stains that remain without being separated into the sanitary products in this way are dissolved and separated from the sanitary products by the pulverization of the sanitary products, and the amount of the soil remaining in the materials. Decreases significantly. On the other hand, in the rinsing and washing stage, solid dirt such as feces remaining without being separated in the sanitary product is mostly pulverized together with the sanitary product, and a part thereof is dispersed in the solution. Further, the pulverized sanitary product is washed and a part of the soil is separated by the stirring treatment in the disinfectant solution. It is sterilized together with dirty dirt. In order to separate the sanitary product material treated in this way, the disinfectant solution in which the sanitary product material is suspended may be, for example, a sieve or filter with openings or pore sizes of 0.5 to 5 mm. It is sent to a solid-liquid separator equipped with a cloth. Because of the stirring treatment in the disinfectant solution, most of the water-soluble stains and solid stains adhering to the sanitary product pulverized product are dissolved or suspended in the disinfectant solution. By separating with a solid-liquid separator equipped with a sieve or filter medium with a thickness of 0.5 to 5 mm, most of the water-soluble stains and solid stains adhering to the sanitary goods will be contained in the sieve or the filtrate. Separated from sanitary materials on sieve or filtration residue. The material of the sanitary article thus separated is washed under stirring in a further disinfectant solution. By repeatedly treating in the disinfectant solution in this way, the number of bacteria remaining in the sanitary product material is significantly reduced.
[0019]
In the present invention, the pulverized sanitary product is rinsed and washed under water in a disinfectant-containing water, thereby killing bacteria attached to the sanitary product material and significantly reducing the number of bacteria. The sanitary material thus cleaned is subjected to sieving treatment under vibration with a sieve having an aperture of 0.5 to 5 mm, preferably 0.5 to 1 mm. On the sieve, a sieving product mainly containing a plastic substance wetted with water containing a disinfectant and a gelled superabsorbent resin is obtained, and sewage containing a disinfectant containing dirt is separated under the sieve. The
[0020]
In the present invention, a sieve having a sieve mesh of 3 to 10 mm, preferably 4 to 6 mm is used to separate the plastic material. In this case, the superabsorbent resin under the sieve is a gel-like substance by absorbing the superabsorbent resin, and is preferably 0.3 to 2 mm in order to separate the gel-like superabsorbent resin from water. Is sieved with a sieve having a mesh size of 0.5 to 1 mm. The separated superabsorbent resin is dried by a dryer, for example, a blow dryer. The dried superabsorbent resin can be used as a raw material for sanitary goods.
[0021]
In the present invention, the disinfectant is used for sterilizing bacteria adhering to dirty sanitary goods, and ozone, chlorine, liquid chlorine, sodium hypochlorite, bleaching powder, high bleaching powder (calcium hypochlorite) ), Calcium hypochlorite, lithium hypochlorite, organic chlorine agent, chlorine dioxide, ozone, chlorine bromide, chlorinated isocyanuric acid, chloramine B or chloramine T can be used. However, in addition to these disinfectants, disinfectants, antibacterial agents, or disinfectants that are generally used for disinfecting bacteria or microorganisms can be used. In the case of using a disinfectant solution as a means for sterilizing germs of sanitary goods, the concentration of the disinfectant is increased when the treatment time is shortened. However, if the treatment time is 30 minutes or more, the disinfectant can be used at a concentration that is normally used. For example, in the case of a sodium hypochlorite solution, it is used in an amount of 0.05 to 3% by weight. However, the results of disinfection can be examined, and the amount can be appropriately increased or decreased each time. Ozone has a high decomposition rate and a high sterilizing power, and sterilizes in a short time. However, chlorine has a small sterilizing power compared to ozone and requires a long time for sterilization. However, since the chlorine disinfectant has a longer sterilizing power than the ozone disinfectant, it is preferable to use liquid chlorine, sodium hypochlorite or calcium hypochlorite in the present invention. Regarding the concentration of the disinfectant solution, it is preferable to set the concentration of the disinfectant solution used according to the type of soiled sanitary products, the state of soiling, and the processing time.
[0022]
In the present invention, pulverization of used sanitary sanitary products is preferably carried out batchwise in water containing a disinfectant in order to effectively use the time required for disinfection. However, in the present invention, in order to disinfect the pulverized sanitary product material, the sanitary product pulverized product from which a part of the soil has been separated is subjected to the disturbance of the rotating device of the pulverizer in the disinfectant solution. Sanitized.
In the present invention, for example, bacteria that have been heated and dried with hot air at 100 to 120 ° C. and adhered to the sanitary product material can be sterilized by heat, and the Escherichia coli adhering to the regenerated and recovered sanitary product material can be made negative. can do. Generally, the number of bacteria before sterilization of disposable medical products is, for example, 10 for raw cotton.⁶Thru 10⁷/ 1g, 10 cotton wool²Thru 10^Four/ G and 10 gauze²Thru 10^FourHowever, in the present invention, at least the number of bacteria in the sanitary product material collected in the present invention can be less than or equal to the number of bacteria before sterilization of the exemplified disposable medical product. In the present invention, Escherichia coli is killed and formed into a body, and it is rarely left, so it is not a sanitary problem.
