Description

Detailed Description of the Invention [Field of Industrial Application] The present invention relates to a filtration material used for filtration of fluids in various cleaners, and more specifically, for filtration of minerals, animals, plants, oils, etc. in fluids, and water, water, etc. The present invention relates to filtering materials for removing iron, sulfur, calcium, salt, etc., removing moisture and odors from the air, or separating oil and water, and removing those odors and pigments.

[Conventional technology]

A filter medium used when filtering a fluid generally has sieve-like properties for trapping solid particles in the fluid. However, in addition to the solid particles mentioned above, the fluid also contains various foreign substances such as moisture, odors, pigments, fine iron, sulfur, salt, calcium, and even fluorine and manganese. cannot be removed with a sieve. For this reason, in the past, odors and pigments were removed by using adsorbents such as activated carbon and activated clay in filter media.
Alternatively, a method is used in which water is removed by using a water-absorbing resin in combination. Further, when removing fine magnetic particles such as iron, a magnetic filter medium is used in combination to remove these fine magnetic particles.

[Problem that the invention seeks to solve]

However, with the conventional filter media mentioned above, it is possible to remove odors, pigments, water, and fine iron by using magnetic filter media, activated carbon, activated clay, and other adsorbents. It has not been possible to remove foreign substances such as sulfur, salt, calcium or fluorine, manganese.

In view of the problems of conventional filter media as described above, the present invention is a filter material used for filtering fluids that can not only remove odors, pigments, moisture, iron, etc., but also remove other substances such as sulfur and salt. It is an object of the present invention to provide a filtration material that can efficiently trap and remove foreign substances such as calcium and prevent a large decrease in filtration performance.

[Means for solving problems]

In order to solve the above-mentioned problems, the present invention uses a filter medium made of porous tape-shaped paper, cotton cloth, nonwoven fabric, etc., formed into a thread or rope shape. It is an object of the present invention to provide a filtration material characterized in that a nucleic acid-acting enzyme agent is incorporated at the same time as the filter material is formed.

[Effect]

The configuration of the filtration material according to the present invention is as described above, and if a fluid is filtered using this filtration material, for example, wound around a bottle or formed into a sheet,
In addition to the foreign matter removal function that the filter medium inherently has, the nucleic acid acting enzyme agent that is involved in the filter medium forms a compound with the foreign matter to solidify the foreign matter, which is efficiently captured by the filter medium.
It is to be removed.

[Details of the invention] The explanation will be explained in more detail.

The present invention not only makes it possible to efficiently remove pigments, odors, moisture, iron, etc. by using a nucleic acid acting enzyme agent in combination with conventional filter media, but also makes it possible to efficiently remove pigments, odors, moisture, iron, etc. that cannot be captured and removed with conventional filter media. This is based on the knowledge that salt, calcium, and sulfur can also remove fluorine, manganese, etc.

Originally, solids in fluids were removed using membrane filters, but while this can remove large solid particles, it is difficult to remove fine particles. However, there was a problem in that the film was clogged by the captured solid particles, resulting in a significant decrease in filtration efficiency.

Therefore, we used a filter medium made of tape-shaped paper or non-woven fabric shaped into a thread or lobe shape, and in addition, we used a filter medium made of tape-shaped paper or non-woven fabric.
By using activated clay, etc., solid particles can be removed without significantly reducing filtration efficiency, and iron, pigments,
Methods for removing odors and the like are also known. However, even with this method, it is still difficult to remove salt, calcium, sulfur, etc. Therefore, in the present invention, a nucleic acid acting enzyme agent is used in combination with these conventional filter media, and when the filter medium is wound into a thread or tape shape and the nucleic acid acting enzyme material is rolled in at the same time, the above-mentioned conventional filter media can be improved. This makes it possible to remove salt, calcium, sulfur, etc. that could not be removed with other methods, and also prevents the removal efficiency from decreasing.

As the nucleic acid-acting enzyme agent used in the present invention, pineapple enzyme is particularly effective for removing foreign substances, which is the object of the present invention.

Further, as the porous filter medium to be used, paper, cotton cloth, nonwoven fabric, etc. are employed, and when a nonwoven fabric is used as the filter medium, a wet type filter without using a binder is preferable. In particular, it is preferable to use a pulp nonwoven fabric as a filtration material for the purpose of separating oil and water, and when removing foreign substances from water, pulp containing a synthetic resin such as polypropylene can also be used.

The filtration material according to the present invention is produced by simultaneously rolling in a nucleic acid-acting enzyme agent such as pineapple enzyme when forming the above-mentioned filter medium into a thread or rope shape. However, as the filter medium, it is also possible to use a conventionally used adsorbent such as activated carbon, activated clay, or magnetic material, and in this case, these various adsorbents may be used. A filtration material is formed by simultaneously incorporating a nucleic acid-acting enzyme agent into the filter material during molding.

According to the filtration material of the present invention produced as described above, it is possible to remove salt, sulfur, calcium, fibres, manganese, etc. that could not be captured and removed by conventional filter media. Instead, the filter medium is a porous tape-like material formed into a thread or rope shape, so if it is wound around a bobbin or formed into a sheet shape and used for fluid filtration, the filtration efficiency will be reduced. By using activated carbon, activated clay, water-absorbing resin, etc., which are conventionally used in combination with filter media as mentioned above, in addition to the inherent adsorption effect of these adsorbents, the fluid can be filtered without causing any Foreign matter in the fluid can be efficiently removed by the resulting foreign matter trapping action.

Next, the effect of removing foreign matter in various embodiments of the filtration material according to the present invention will be explained.

First, filtration materials made by simultaneously rolling pineapple enzyme into a porous filter material such as tape-shaped cotton cloth, paper, or nonwoven fabric and forming it into a thread or rope shape are effective in dechlorinating and removing chromium, nickel, etc. do. In this case, chromium (hexavalent chromium) comes into contact with the pineapple enzyme and becomes chromium oxide, which is captured by the filter medium and removed from the fluid.

Furthermore, when a filter material containing pineapple enzyme and ammonium chloride is used as the filter material,
It is particularly effective in removing radioactive elements from tap water. This is because the ammonium chloride used with the pineapple enzyme reacts with the filaments and converts into linear ammonium, which efficiently removes the filaments.

In addition, when a filter material formed by incorporating pineapple enzyme, green zeolite, and activated clay is used as a filter material, it has decolorizing and deodorizing effects as well as oil-water separating effects. In this case, activated carbon can also be used instead of the activated clay. Although it has been known to deodorize and decolorize edible oils such as tempura oil using activated carbon or activated clay, it has not been possible to remove the moisture in the oil. However, by using the filtration material of the present invention as described above,
This made it possible to decolorize and deodorize edible oils such as tempura oil, and at the same time remove water from the oil.

Next, when a magnetic material such as ferrite is simultaneously incorporated into the filter material along with pineapple enzyme and formed into a filter material, in addition to the iron removal effect of the magnetic material such as ferrite, sulfur or calcium content can also be removed. It is possible and effective in removing sulfur content, calcium content, etc. from groundwater.

Furthermore, silica sand, along with the above-mentioned pineapple enzyme and magnetic substance,
When clay, green zeolite, activated carbon, etc. are used together, chlorine, manganese, etc. can also be removed, making it useful for filtering tap water, underground water, etc. When using this magnetic material, in order for the magnetic material to be uniformly distributed in the filter media such as paper, cotton cloth, nonwoven fabric, etc. without forming lumps, the magnetic material that is not initially magnetized is rolled into the filter media. After forming the filter medium, it is preferable to magnetize it by passing it through a magnetic field such as a permanent magnet.

Next, the method for manufacturing the filtering material 1 according to the present invention will be explained based on the attached drawings. FIGS. 1 and 2 show the filtering material 1 according to the present invention, and FIG. is a side view of the filter material 1, and FIG. 2 is a cross-sectional view thereof. The filtering material 1 is made of pineapple enzyme, or pineapple enzyme and magnetic material, and other powders such as activated carbon and activated clay, in a tape-like filter material 2 made of air permeable or water permeable paper, cotton cloth, nonwoven fabric, etc. A mixture 3 with an adsorbent and the like is rolled up, and the entire filter medium 2 is formed into a thread-like or rope-like filter material 1 with twist added thereto.

3 to 7 show a method of manufacturing the filter material 1. For example, a tape-shaped filter material 2 cut to a width of 50 mm and wound around a bobbin 4 is fed out while rotating the bobbin 4, and a pair of filter materials 1 are produced. It passes between the folding rolls 5a and 5b. With these folding rolls 5a and 5b, the filter medium 2 is folded into two parts as shown in FIG.
When the filter medium 2 is folded and passes through the folding rolls 5a and 5b, it expands into a V-shaped cross section as shown in FIG. 5 due to the elastic force of the filter medium 2 itself. Here, pineapple enzyme or a mixture 3 of pineapple enzyme and a non-magnetized magnetic material or other granular adsorbent is continuously charged into the concave portion of the filter medium 2 from a measuring hopper (not shown). folding roll 7a
, 7b. These folding rolls 7a and 7b are for folding the upper part of the filter medium 2, which has expanded into a V-shape, inward from both sides to cover the pineapple enzyme or the mixture 3 of pineapple enzyme and adsorbent. In order to fold the filter medium 2, as shown in FIG. 3, the filter medium 2 is placed at positions shifted from each other along the length direction, and the upper part of the filter medium 2 is bent as shown in FIG. Wrap up mixture 3.

Next, the filter medium 2 encasing the pineapple enzyme as described above is passed through the tapered cone 8 to enclose the pineapple enzyme or the mixture 3 of the pineapple enzyme and adsorbent, and the filter medium 2 is as shown in FIG. Narrow it down and regulate its diameter to, for example, about 3 ml.

Furthermore, when a magnetic substance is used in combination with the pineapple enzyme, permanent magnets 9a, 9 are used to magnetize the magnetic substance.
The magnetic material is magnetized by passing it through the magnetic field formed by b. If no magnetic material is used, the magnetization step is omitted. Next, the filter medium 2 is rotated by an electric motor 10, and a winding drum 11 is further rotated by a twisting electric motor 12.
The filtration material 1 is twisted while being rolled up to form a mechanically stable state in which the pineapple enzyme or the mixture 3 of pineapple enzyme and adsorbent will not spill out. By forming it in such a state, it has a sieve-like effect of removing solid particles as described above, and also prevents clogging caused by the solid particles and causing a large decrease in filtration efficiency, and allows the filtration material 1 to be formed together with the filter medium. As a filtration material that has the ability to remove fine iron, moisture, salt, sulfur, calcium, manganese, etc., separate oil and water, and further decolorize and deodorize using pineapple enzyme or various adsorbents made in combination with pineapple enzyme. It is what it is.

In addition, in the above manufacturing method, when winding up the filter medium 2,
Since the winding drum 11 is rotated to impart twist, the length of the completed filter material 1 is approximately the same as the length of the original tape-shaped filter material 2. When wrapping the mixture 3 with the adsorbent, the filter material 2 may be spirally wound to give twist to the filter material. At this time, the length of the completed filter material 1 will be shorter than the length of the original filter material 2.

When actually using such filter material 1,
For example, it can be applied to an oil cleaner 13 as shown in FIG. The oil cleaner 13 has an oil inlet 15 and an outlet 16 on the upper surface of an outer container 14 made of a cylindrical metal tube, and a filter body 17 is supported by a spring 18 in the outer container 14. 17 is surrounded by an oil-proof bottom plate 19 and a closing plate 20 on the top and bottom,
The inner and outer sides are surrounded by a cylindrical outer wall 21 and an inner cylindrical wall 22 through which oil passes. The bottom plate 19 and the closure plate 20 are made of, for example, rigid metal plates, and have a cylindrical outer wall 21 and an inner wall 22.
is made of wire mesh or porous metal plate, for example hunting metal. The filter body 17 is formed of the filter material 1 according to the present invention, and is wound around the cylindrical inner wall 22 with the cylindrical inner wall 22 as a core. At this time,
It is preferable that the portion close to the cylindrical inner wall 22, that is, the beginning of the winding, be densely wound, and that the portion closer to the inner wall 22 of the cylinder be wound more loosely as it progresses to the outside. By doing this, the oil flows from the oil inlet 15 to the cylindrical outer wall 2.
1, passes through the filter body 17, and passes through the inner wall of the cylinder.For foreign substances with different particle sizes in the oil, foreign substances with large particle sizes are captured on the upstream side of the filter body 17, and those with small particle sizes are captured on the downstream side. This allows the filter body 17 to capture
This prevents clogging and extends the life of the filter body 17.

The filter material 1 according to the present invention is not only used in a state wound around a bobbin as described above, but also can be formed into a sheet shape by knitting or weaving the filter material 1 to be used as a filter cloth or an adsorption cloth. It is also possible to use
