Description

[Detailed description of the invention] Industrial application field The present invention relates to a filtration attachment for filtering water used once in hot springs, public baths, swimming pools, etc., and for reusing it. This invention relates to a filter attachment for a filter that circulates and filters water.

BACKGROUND ART Conventionally, various types of filtration attachments have been proposed for filtering polluted water using pumps. Broadly speaking, these filtration attachments are:
They can be divided into those that can be used multiple times by cleaning, etc., and those that are disposable and can be discarded after one use.

For items that are used multiple times for cleaning, etc., it is possible to use high-quality filtration attachments at a somewhat high price. It is impossible to sufficiently remove clogging due to

In addition, disposable filtration attachments require at least a low material cost for the disposable part.
In terms of maintenance costs, it is difficult to replace and use the filter attachment. Therefore, low-cost, high-quality materials for filtration attachments are required. However, conventional filtration attachments for filtering water, particularly in hot springs, public baths, swimming pools, etc., have not fully satisfied users in terms of quality and price.

Problems to be solved by the invention The present invention was made in view of the above-mentioned problems and provides a new filtration attachment, which is made by laminating inexpensively available cotton fibers such as cotton fibers and water-soluble paper. The present invention aims to provide a filtration attachment capable of high-quality filtration at an extremely low price.

Means and Effects for Solving the Problems The filtration attachment according to the present invention is removably attached to the inside of a filter that performs filtration by forcibly circulating water using a pump. Filtration is performed by replacing the filter attachment. For this purpose, a thick filter layer of cotton fibers such as cotton fibers is formed around the outer periphery of the mesh tube, and water-soluble paper is wrapped around the outer periphery.

Here, when talking about the case where cotton fiber alone is used as a filter medium, cotton fiber alone can pass not only fine organic matter but also small diameter sand, etc.
It is particularly unsuitable for filtering water from hot springs, swimming pools, etc. that has been used once.

The present invention is characterized in that water-soluble paper is wrapped around the outer periphery of the filter layer made of cotton fibers.

This filter layer and water-soluble paper are used to filter out fine organic substances and sand that are mixed in the water from hot springs, public baths, swimming pools, etc. In addition to filtering out the contaminants, the water-soluble paper penetrates into the filter layer made of cotton fibers such as cotton wool, and the synergistic effect of the cotton fibers and the water-soluble paper makes it especially useful for hot springs and swimming pools that have been used once. It is capable of sufficiently filtering out fine organic substances, which are the main cause of water contamination.

Embodiment Hereinafter, an embodiment of the filtration attachment according to the present invention will be described in detail with reference to the drawings.

FIG. 1 is a longitudinal sectional view of an embodiment of the filtration attachment according to the present invention, and FIG. 2 is a cut end view of the filtration attachment taken along line A-A in FIG. mounting pipe,
3 is a mesh tube, 4 is an inner cloth, 5 is a filter medium layer, and 6 is water-soluble paper.

The filter attachment 1 is constructed by sequentially stacking an inner cloth 4, a filter medium layer 5, and a water-soluble paper 6 on the outer periphery of a mesh tube 3 that is fixed to a mounting pipe 2 by welding, adhesive, or the like.

The mounting pipe 2 is provided with a threaded portion 2a for removably attaching it to the water outlet of the filter.
The filter is replaced with a new one to continue filtration. The threaded portion 2a does not necessarily have to be a screw, and can of course be formed by various attachment means such as a flange or a bayonet.

On the outer periphery of the mesh tube 3 fixed to the mounting pipe 2,
An inner cloth 4 is provided in close contact with each other. The inner cloth 4 is a fine-mesh cloth such as nylon, and is used to prevent the cotton fibers of the filter layer 5 made of fallen cotton from passing through the mesh tube 3.

Although the mesh pipe 3 is a cylindrical mesh, the mesh of the mesh pipe 3 may be made finer, or a large number of filter holes may be formed in the pipe as one unit with the attached pipe.

The filter medium layer 5 is provided with a thickness on the outer circumference of the inner cloth 4. A preferred material for use as the filter layer 5 is cotton lint used for work gloves, etc. Sewing waste made of other cotton fibers can also be used. Further, the filter layer 5 does not need to be cloth-like, and may be fabric waste from cotton products discarded from spinning factories, sewing factories, etc.

The water-soluble paper 6 is arranged to cover the outer periphery of the thick filter medium layer 5, that is, the outermost periphery of the filter attachment 1. This water-soluble paper 6 does not need to be wrapped thickly several times, but is wrapped around once or several times.

The water-soluble paper 6 initially filters out fine organic substances, sand, etc. at the outermost periphery of the filter attachment 1 by itself, but gradually dissolves in water and penetrates into the filter layer 5. Fill in the gaps created by single cotton fibers. In this way, due to the synergistic effect of the bond between the water-soluble paper 6 dissolved in water and the cotton fibers of the filter medium layer 5, fine organic matter, sand, etc. mixed in the water from hot springs, swimming pools, etc. that have been used can be sufficiently removed. can be removed.

These inner cloth 4, filter medium layer 5, and water-soluble paper 6 are firmly attached to the mesh tube 3 with a ring fitting 7. Needless to say, the inner cloth 4, the filter medium layer 5, and the water-soluble paper 6 can be attached using various conventional attachment means other than the ring fitting 7.

Here, the fibers used for the filter medium layer 5 are preferably cotton fibers. For example, if synthetic fibers such as polyester or polyamide are used, the water-soluble paper 6 cannot penetrate into the inside of the filter medium layer 5, and the outermost periphery of the filter attachment 1 It forms a hard layer with the filtered waste, making it impossible to perform effective filtration.

In addition, regarding the replacement period of this filter attachment 1, when using it in a normal public bath etc.
With one filtration attachment, filtration can be performed continuously for about 1 to 2 months.

Next, a case will be described in which an embodiment of the filtration attachment according to the present invention is used in a filter.

Figure 3 shows the filter attachment 1 as a cylindrical filter 8.
FIG.

The filtration attachment 1 is removably attached by screwing a threaded portion 2a formed at the end of an attachment pipe 2 to a threaded portion 13a of a water outlet pipe 13.

The cylindrical filter 8 is composed of an outer cylinder 9 having a water inlet 11 and a water outlet side part 10 having a water outlet pipe attachment part 10b, and is integrally attached by fitting flanges 9a and 10a and being removable with bolt nuts 14. It is being Outlet pipe mounting part 10
A water outlet pipe 13 having a water outlet 12 is fixed to b, and as described above, the threaded portion 1 of the water outlet pipe 13
The filtration attachment 1 is attached to the inside of the cylindrical filter 8 by screwing the threaded portion 2a of the attachment pipe 2 onto the cylindrical filter 3a.

When performing filtration, water from a hot spring, swimming pool, etc. that has been pumped up by a pump or the like and used once is sent through the water inlet 11 and flows from the outside to the inside of the filtration attachment 1 to perform filtration.
The filtered water passes through the water outlet pipe 13 to the water outlet 1.
It will flow from 2.

After performing filtration in this manner for a certain period of time, the outer cylinder 9 is removed and the filtration attachment 1 is replaced. Here, the used filter attachment 1 may not be discarded as it is, but may be collected in one place, the inner cloth 4, the filter medium layer 5, and the water-soluble paper 6 replaced with new ones, and then supplied again.

Furthermore, the filtration attachment according to the present invention is
In addition to the cylindrical filter 8, various types of pump-based filters can be used.

Effects of the invention As explained above, the filtration attachment according to the present invention is a filtration attachment that can perform high-quality filtration at an extremely low price by using cotton fibers such as cotton fibers and water-soluble paper that are available at low cost. It will be provided at
