Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-valve pleated filter used for stacking and filling in a purifying device such as a water purifier or an air filter, and an apparatus for manufacturing the same.

[0002]

2. Description of the Related Art Charcoal material (activated carbon) is widely known as a filling material that is stacked and filled in a water purifier, for example, so that impurities are adsorbed and absorbed in a large number of minute pores formed. Has become.

[0003]

By the way, this activated carbon is naturally high in cost because it is necessary to use natural trees, especially limited kinds of trees to obtain good characteristics. At the same time, since it is a natural resource, there is a significant limitation on the amount that can be obtained. Further, this activated carbon has relatively high adsorption / absorption of unwanted substances, and although its effect is convincing to some extent, it was impossible to expect a stronger effect.

In view of the above circumstances, the present invention has been made in view of the above circumstances.
To provide a multi-valve pleated filter capable of mass production, obtained at a relatively low cost, and capable of strong adsorption and absorption by using an appropriate material as a material, and a manufacturing apparatus thereof. It is intended.

[0005]

That is, the invention according to claim 1 is a filter in which a large number of them are integrated and used to purify air or water, or to absorb or change odors. It has a large number of thin film folds having a large number of holes and / or projections and having a bent petal shape formed on the surface.

The manufacturing apparatus for a multi-valve pleated filter according to the second aspect of the present invention is a columnar or prismatic apparatus for feeding a raw material having a large number of holes or particles by a fixed length without rotating the raw material. A cutting means for cutting the raw material fed out by this feeding mechanism along the outer surface while cutting it from the tip portion into a thin-walled portion, and a large number of petal-shaped curved surfaces on the thin-walled portion cut by the cutting means. And an abutting means for forming the whole into a lump.

[0007]

The multi-valve pleated filter of the present invention is formed in a lump shape as a whole having a large number of thin film folds, whereby the surface area in a constant volume can be maximized. Moreover, since a large number of holes and / or projections are formed on this surface, the maximum number of holes and / or projections in a fixed volume can be secured, and a strong adsorption force or absorption force can be exhibited.

[0008]

Embodiments of the present invention will be described below with reference to the accompanying drawings. FIG. 1 shows a multi-valve pleated filter 1 according to the present invention.
Has a large number of curved petal-shaped thin film folds 11 and has a lump shape as a whole, and is formed in a spherical shape (or a flattened spherical shape that is slightly crushed) in this embodiment.

As shown in FIG. 2, a large number of fine holes 11A are formed in the thin film fold 11, and the surface area is further increased by this. Instead of these holes, innumerable fine particles having a large number of fine holes may be fixed.

Therefore, according to this embodiment, in the multi-valve pleated filter 1 formed into a spherical shape (or a flattened spherical shape which is slightly crushed), a large number of folds 11 and finely spread over the entire surface of the folds 11. 11A (or fine particles provided with a large number of fine holes). As a result, the surface area has increased dramatically even with a small volume,
Adsorption power and suction power are significantly increased, and by using a large number of these as a water purifier or a purifier, the purification capacity is significantly increased.

Further, for example, when the multi-valve pleated filter 1 is housed together in a breathable container and dropped into the sea, a river, a lake or the like, a bacteria house in which natural bacteria settle in fine holes and the like. , Which allows the purification of sewage. It should be noted that the same effect can be obtained by dropping the wastewater into a sewage box for treating sewage. Further, by using the nylon-based multi-valve pleated filter 1, it is possible to exert a strong dust collecting action by static electricity due to friction or the like.

Next, an apparatus for manufacturing a multi-valve pleated filter according to the present invention will be described. FIG. 3 shows a main part of a multi-valve pleated filter manufacturing apparatus according to the present invention, which is used for manufacturing a multi-valve pleated filter 1 (see FIG. 1) at a constant speed. , A cutting means 3 for cutting the raw material 1'into a thin wall shape, and a thin wall portion curved in a petal shape as a whole, in this embodiment, spherical (or slightly crushed). And an abutting member 4 formed into a flattened spherical shape.
In addition, reference numeral 5 in the drawing denotes a blade exchanging mechanism for accommodating a plurality of kinds or the same cutting blades or abutting members so as to be freely taken out in order to replace the cutting blade 31 and the abutting member 4 with another one. (For this, the applicant of the present application has filed a similar one without an abutting member, and Japanese Patent Application No. 5-475
No. 09).

As the raw material 1 ', for example, a cylindrical or prismatic porous material (plastic, ceramics, various natural materials) having a large number of fine holes can be used.
In addition, after forming a multi-valve pleated filter, predetermined particles (for example, heavy metals (Ag, Cu, etc.) are ionically bonded to the periphery of a porous material, that is, particles having an ionized metal supported on the entire surface). It may be configured such that a large number of them are fixed to each other.

A feed roller 22 forcibly rotated by a motor 21 is used as the feed means 2, but the feed means 22 is not particularly limited to this, and various known means can be applied. The feeding means 2 is controlled by a control unit (not shown), and feeds the raw material 1'at a constant rate each time at a constant speed, then stops the feeding operation for a given time, and feeds the raw material at a given rate. The material 1'is cut.

The cutting means 3 continuously cuts the raw material 1 ′ sent by the sending means 2 along the outer periphery from the tip portion in a thin-walled manner for a predetermined length, and is shown in the drawing. A cutting blade 31 is attached to the tip end surface of a cone member 32 rotated by an external motor.

As shown in FIG. 4, the abutting member 4 is provided on the downstream side of the cutting blade 31 in the feed direction of the raw material 1 ′, and in this embodiment, the tip is more constant than the cutting edge of the cutting blade 31. They are provided at positions separated by the amount d. Further, the abutting member 4 of this embodiment is provided so that its tip is located slightly outside the center of the raw material 1 '. The abutting member 4 of this embodiment is formed in a shape that is bent back toward the downstream side in the delivery direction of the raw material 1 ', but the shape is not particularly limited to this, and the same effect can be obtained. If so, various shapes are possible. Further, this abutting member does not have to be rotated integrally with the cutting blade, and only this abutting member may be fixed at a fixed position.

Therefore, according to this embodiment, there is a thermal temperature difference between the contact surface and the non-contact surface of the abutting member 4 in the cut raw material 1 ', that is, the contact surface with the abutting member 4 is made. Are heated to a high temperature due to friction, and the cut portions are curved due to the difference in expansion amount to form petals, and the petals are closely overlapped with each other to form a substantially spherical shape (or a flattened spherical shape that is slightly crushed). It is formed.

[0018]

As described above, according to the multi-valve pleated filter according to the present invention, the whole shape having a large number of thin film folds is formed in a lump shape, whereby the surface area in a constant volume can be secured to the maximum. Like this,
Moreover, since a large number of holes and / or protrusions are formed on this surface, the maximum number of holes and / or protrusions in a fixed volume can be secured, and a strong adsorption force or absorption force can be exhibited.
