Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage bag (filter) installed at a drain of a sink in a home, shop, workplace, or the like so that the drainage bag is less likely to be clogged. It relates to a draining aid that can be used.

[0002]

2. Description of the Related Art Cylindrical baskets attached to drains of sinks are designed to prevent large trash from flowing into drainage and to prevent clogging of drain pipes. Will pass through the basket and get into the wastewater, placing a heavy burden on wastewater treatment.

However, with the recent awareness of the prevention of environmental pollution, it has been practiced to install a draining bag (filter) in the above-mentioned basket and perform filtration to prevent smaller garbage from flowing. , As a drain bag for that,
For example, bags made of nonwoven fabric made of polypropylene fibers or other fibers are commercially available. This draining bag is used by setting it in a basket and then bending the upper part toward the outside of the basket (in the case of a drainage basket, further put a lid from above).

[0004] In this case, the finer the non-woven fabric forming the drain bag, the smaller the garbage will not escape into the waste water, which is preferable from the viewpoint of reducing the burden of waste water treatment and preventing water pollution of rivers.

[0005] In particular, when a drainage bag made of a non-woven fabric containing polypropylene fibers is used, the fineness of the fine fibers makes it possible to catch small dust, and the fineness of the constituent fibers makes the surface area large and the material In general, since polypropylene has oil absorbency, there is an advantage that oil coming out of the kitchen is also removed to some extent.

[0006]

However, since the removal rate for removing even small dust and the drainability are inherently contradictory, the drainage bag made of nonwoven fabric becomes more clogged as the removal rate is improved. Cheap. For this reason, when fine particles, oily substances, pastes such as curries and stews, and juice scum, etc., are passed through a sink,
Since the clogging occurs immediately, there is a trouble that frequent replacement is required, and the cost burden is increased.

In order to avoid clogging, there is a psychological effect of using a drainage bag made of a coarse nonwoven fabric, or omitting the set of the nonwoven fabric drainage bag itself to drain water. If clogging can be prevented even with the use of a nonwoven drainage bag made of a fine-grained nonwoven fabric, its practical significance and environmental pollution prevention significance will be extremely large.

[0008] Under such a background, the present invention can reduce clogging significantly even if a fine drainage bag is used as a filter medium, even though the tool has a simple structure, The purpose of the present invention is to provide drainage drainage aids that reduce the burden of wastewater treatment and prevent river water pollution and contribute to environmental pollution prevention, and to provide nonwoven fabric drainage bags for that purpose. It is.
