Description

The present invention relates to a structure of a liquid absorber that effectively absorbs water, ice creams, shakes, etc. mixed with fats and oils in waste generated at large restaurants, etc. It is put in a normal trash box installed in, and these liquids are discarded and absorbed here and disposed as general waste.

  With the widespread use of large restaurants and fast food restaurants, the properties and absolute amount of wastewater are changing in an unfavorable direction.

  For example, in the case of a hamburger shop of a certain size or more that operates in the suburbs of the city, examples of solid waste include various types of leftover food, packaging bags, containers, paper napkins, disposable tableware These are disposed of in a trash box installed in a store or a kitchen, and are collected and treated as general waste or industrial waste.

  On the other hand, liquid waste is processed by consigning a specialized recovery company for complete fats and oils (for example, deep-fried oil), but enormous amounts of oils and fats containing water (meat juice, ice cream, shakes, etc.) are generated. Nevertheless, there is no simple means for processing.

The most common method is to discard in a sink in the kitchen and separate the oil and water with equipment such as a grease trap. Such equipment is often required to be installed by law, and theoretically it can be processed without any problems. Furthermore, a technique has also been proposed in which a chemical or a microorganism is introduced into a grease trap to decompose oil.

  However, in reality, work that should be performed frequently and regularly, that is, oil removal from the grease strap and cleaning work are indispensable for maintaining the capacity, but in reality, they tend to be neglected. Accordingly, the processing capacity of facilities tends to be much lower than the design capacity at many stores. In addition, depending on the equipment installed in the kitchen, for example, certain types of soft cream making machines may require periodic cleaning work from a hygienic point of view, in which case they remain in the container. All liquids (soft cream) must be discarded. The remaining amount is 10 to 20 kg in the case of an average capacity soft cream making machine. When this amount of liquid is discarded through the kitchen sink, the amount of liquid depending on the grease wrap is large, and since it is emulsified, oil-water separation is difficult to perform effectively. This means that there are many stores that are in a very serious situation where clogged, emulsified liquids that are difficult to separate oil and water are put in an amount that exceeds the initial setting in facilities that cannot demonstrate their initial capacity. .

  In view of the above points, the inventors of the present invention have intensively studied and finally achieved the present invention. The feature of the present invention is that the liquid that has been thrown into the container is absorbed in advance. It is for the purpose, and it is in the point which made the fibrous material into a lump.

  Here, the “container” is not limited in its structure, material or the like in the present invention. Although the same thing as the conventional trash can installed in a kitchen etc. is employable, of course, you may prepare separately the trash box for solid waste, and the trash box only for liquid injection. Further, in consideration of convenience at the time of disposal, dirt on the trash due to liquid leakage, etc., it is desirable to set the plastic trash bag in advance in the trash.

  There is no particular limitation on the “fibrous material” for absorbing liquid, but there is a difference in absorption capacity, degree of environmental pollution at the time of disposal, etc. It is preferable to select one having a low possibility of environmental pollution. As far as the present inventors have experimented, with regard to the ability to absorb oil and water, synthetic fibers and natural fibers are more suitable than paper made of pulp. In the case of absorption, cotton was superior to other fibers, and kapok fibers were superior in the absorption capacity of oil alone. In addition, some synthetic fibers have a large absorbency, but considering the harmful effects on the environment when disposed as general waste, they are not necessarily the optimum material.

  The structure of the fibrous material may be a knitted fabric, a non-woven fabric, or a cotton-like body. However, as a result of experiments conducted by the present inventors, a cotton-like body (with a fibrous structure such as futon cotton or absorbent cotton) was suitable. . Therefore, a fibrous material containing 50% by weight or more of natural cotton (cotton) is optimal. This is exactly the same as the waste that is generated as a scrap when producing a disposable makeup remover sheet, which can be used in an almost unprocessed state. This disposable makeup remover sheet is made by covering the front and back of the absorbent cotton made into a sheet with gauze-like cotton cloth, and cutting it into narrow widths while pressing and heating the vicinity of the edges to melt them. It is manufactured by a method of cutting the shape by a predetermined length. The end material also occurs at both end portions when cutting into narrow widths, and also occurs when cutting the narrow body by a predetermined length. This aggregate of mill ends consists only of a cotton-like body and a gauze-like body, and the weight ratio of the cotton-like body slightly exceeds 60%. Since the mill ends are a mixture of cotton-like bodies and gauze-like bodies, it is practically impossible to collect and re-use them as raw materials for production. Therefore, when this is used as the material of the liquid absorbent body of the present invention, it is possible for the make-up removal sheet manufacturer to dispose of waste that has to be disposed of at an expense almost free of charge (in some cases, profitable form). However, there is a merit that the raw material cost can be extremely small for the manufacturer of the present invention.

  Further, since the fibrous material has a large volume and tends to increase transportation and storage costs, it is preferable to compress it except during use. Specifically, a method of filling a plastic film bag with a fibrous material and reducing the pressure in the bag is preferable. The bag is opened, its volume is recovered, and stored in a trash can. At that time, a larger compression ratio is preferable, but an experimental result that “cotton-like body” is most preferable also in this regard.

In the present invention, in the case where the consumable item is provided with the above-mentioned “bag for compression”, the bag is also included, but is basically only a fibrous material. Only the one that absorbs and holds the liquid or the like is consumed, and as a structure for storing it, a trash can that is naturally installed in the kitchen can be used as it is. Even if a container for absorbing liquid or the like is newly installed and the liquid or the like is discarded, the container will be used repeatedly and need not be discarded. That is, the processing method has a very low running cost.

The liquid absorber according to the present invention has the following effects.
(1) If put in the trash box in advance, the burden on the grease trap and other wastewater treatment facilities will be greatly reduced by discarding the water mixed with oil in the sink.
(2) Since the end material at the time of manufacturing the cotton product can be used as it is, it can be provided at a very low cost.
(3) Since consumables are basically only fibrous materials, it is possible to treat liquids and the like with extremely low running costs.

  Hereinafter, the present invention will be described in more detail with reference to the drawings.

  FIG. 1 shows an example of a liquid absorber 1 according to the present invention (hereinafter referred to as “the present invention absorber 1”). As is clear from the figure, the absorbent body 1 of the present example is composed of a rectangular plastic film bag 2 and a fibrous material 3 filled therein. The size of the absorbent body 1 of the present example in the illustrated state is approximately 200 × 350 × 50 × 50 mm in height, but the fibrous material 3 is particularly preferable because the internal space of the bag is sealed after being decompressed. Compressed in the height direction. Therefore, when opened, the height swells about twice, although it depends on the restoring force of the fibrous material 3.

  FIG. 2 shows a state in which the absorbent body 1 of the present invention is installed in a trash box D installed in a kitchen. First, a plastic film trash bag P is set in the trash box D, and the absorbent body 1 of the present invention is placed therein. The state of the input is illustrated. In this state, the absorbent body 1 of the present invention is sufficiently swollen because it is taken out from the plastic film bag 2. If the liquid (such as gravy or shakes) is discarded here, it will be absorbed by the fibrous material 3.

  At a stage where the liquid is absorbed to some extent, the absorbent body 1 of the present invention is discarded together with the trash bag P. However, when the present inventors inquired to the related ministries and agencies, the trash generated in such a form is “general waste”. "Is likely to correspond. It is a simple processing method that does not go through equipment such as clogging or grease traps.

  The present inventors conducted various experiments in order to find an optimum material and structure as the fibrous material 3 in the present invention. As a result, paper made from pulp absorbs only about the same weight as its own weight, even in the case of toilet paper, which is most capable of absorbing liquids, and paper made from natural cotton uses its own weight in the case of absorbent cotton or spunlace. It was found to absorb more than 2 times. It has also been found that fibrous natural cotton, such as absorbent cotton, becomes very compact when compressed and is excellent in resilience when the compression is released.

  FIGS. 3A, 3B and 3C are diagrams for showing the structure and form of the edge material generated during the manufacture of the “disposable makeup remover sheet” which is one of the most suitable materials for the fibrous material 3. FIG. FIG. Apply gauze-like body 32 (usually “spun lace” is used on both front and back sides of the plate-like absorbent cotton 31; however, if it has the same level of water absorption, it can also be used with the original gauze and other non-woven fabrics. FIG. At that time, the width of the absorbent cotton 31 is wider than that of the gauze-like body 32 so that a product in which the absorbent cotton is lost is not generated. The figure is a plan view, and the gauze-like body 32 on the back side cannot be seen from this figure.

  Next, the multilayer structure is cut into a narrow width [FIG. At the time of cutting, pressure heating devices are arranged on the left and right sides of the cutting blade, so that the multilayer structure is integrated. The pressure contact line B is formed in parallel in the vicinity of the cutting line A. At this time, the strip-shaped end material 42 is formed at both ends of the strip-shaped product material 41, and this is used as the material of the fibrous material 3 according to the present invention.

  Subsequently, the strip-shaped product material 41 is cut at a predetermined interval to complete the product C (disposable makeup remover sheet) [FIG. Also at this time, in many cases, a rectangular end member 43 is formed, which is also the material of the fibrous material 3 according to the present invention. In addition, a defective product C is also a material for the fibrous material 3 according to the present invention.

If the strip-shaped end material 42, the rectangular end material 43, and the defective product C obtained in this way are collected, the absorbent cotton itself has a high water absorption capacity because the cotton fiber wax is removed, and is a very preferable fibrous material. 3 In particular, the generation of the strip-shaped end material 42 is large and inevitable unless the current manufacturing method is drastically improved. Therefore, it can be said that the supply amount is ample.
