JPH08266816A - Bag body simplified filter, cylindrical body for simplified filter and simplified filter - Google Patents

Abstract

PURPOSE: To provide an extremely simple and inexpensive bag-shaped filter body for purifying water by connecting a filter medium housing part fitted with a drainage port successively to the lower end of a bag body which is made of flexible synthetic resin and whose upper end is opened. CONSTITUTION: A water filter is made of a flexible sheet of synthetic resin such as polyethylene. A cylindrical thin sheet is formed into a water storage chamber 1 by opening the upper end and holing lift holes 3 on the right and the left to make them a handle 4. A filter chamber 2 is integrally formed on the bottom surface of the water storage chamber 1, and a drainage port 6 is installed in the tip of the filter chamber 2. When granular active carbon is caused to flow, the filter chamber 2 is filled with the active carbon to form a simplified filter.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extremely simple and inexpensive bag for a simple filtration device and a tube for a simple filtration device which are used for purifying water at home, in the suburbs, in campgrounds, or in overseas travel. The present invention relates to a body and a simple filtration device.

[0002]

2. Description of the Related Art A conventional water filter is composed of highly rigid parts and its manufacturing cost is considerably high.

[0003]

The material of the water filter is composed of a resin sheet such as a soft vinyl sheet and a polyethylene sheet having a thickness of about 0.5 to 0.1 mm, and an extremely inexpensive water filtration device is provided. To get.

[0004]

FIG. 1 and FIG. 2 exemplify the water filtration device of the present invention. A filtration device is used in which a filtration chamber 2 for accommodating activated carbon and other filter media is connected in the center of the bottom of a water storage chamber 1 that swells in a cylindrical shape when water is poured with a soft polyethylene sheet or the like having a thickness of 0.05 to 0.1 mm When not in use, it folds into a flat surface. The diameter of the water storage chamber 1 is 15
If the height is set to 0 mm and the height is set to 200 mm, 2 liters of water can be put, and if the filtration chamber for putting 5 gr of granular activated carbon is 12 mm in diameter and 100 mm in length, it is 10 to 15
Filter 1 liter of water in minutes.

As shown in FIG. 5, if a cylindrical thin plastic sheet 7 is flattened and cut along the contour lines 8 forming the water storage chamber 1 and the filtration chamber 2 one after another, a bag as shown in FIG. 3 is obtained. Can be done. If the bottom of the water storage chamber 1 and the outer edge of the part that becomes the filtration chamber are welded and the part of the upper end of the water storage chamber that becomes the handle 4 is cut off, the upper end is open, so the water is stored in the water storage chamber 1. Water can be taken out from the drain port 6 provided at the lower end of the filtration chamber. A hanging hole 3-3 for hooking is provided in the portion of the carrying hand 4, and an open-cell sponge 5 for preventing leakage of granular activated carbon is inserted at the lower end of the filtration chamber 2. The original sheet of the plastic sheet 7 is 2 instead of the cylindrical sheet.
You may pile up a sheet. When the filtration chamber 2 is cut out, the handle 4 is naturally configured, and continuous production is possible.

[0006]

As illustrated in FIGS. 1 and 2, when raw water is put into the water storage chamber, the container expands into a cylindrical shape because it is soft.
The raw water passes through the filtration chamber 2 containing activated carbon and other filter media and flows out from the drainage port 6 at the end. The flow rate depends on the size of the filtration chamber 2 and the filter medium.

This filtering device made of thin polyethylene sheet of 0.05 to 0.1 mm thickness is a little thicker than a shopping bag in a supermarket, and is 5 to 10 mm.
Even if filled with gram of activated carbon, the price is around 5 to 10 yen. If the whole container is made of polyethylene sheet continuously, one piece can be made in a few yen, so the manufacturing cost is very low and disposable, but the bag is durable and can be used for several months. As for activated carbon, tap water, well water, etc. can filter 1 ton with 5 grams. The filtration chamber 2 may be provided by being filled with activated carbon or other filter material, or a bag made of non-woven cloth or a cartridge filled with activated carbon may be separately prepared and inserted into the filtration chamber 2. Good. When the granular activated carbon is directly filled in the filtration chamber 2, it is possible to prevent the activated carbon from leaking out by inserting a small piece 5 of the open cell sponge into the tip of the filtration chamber 2.

[0008]

EXAMPLE FIG. 2 shows the structure of an example. The carrying hand 4 may be carried by tying the left and right together, or the hanging hole 3 may be hooked on the protrusion. A filtration chamber 2 is integrally formed on the bottom surface of the water storage chamber 1, and a drain port 6 is provided at the tip of the filtration chamber 2, and a sponge 5 is filled as necessary. It is convenient to receive the water from the drain port 6 in a suitable container. It is possible to make a non-woven cloth bag which can be fitted in the filtration chamber 2 and put granular activated carbon, sponge-like activated carbon, fiber-like activated carbon or the like into the bag, and insert and fill the bag into the filtration chamber 2. Alternatively, the open-cell sponge 5 is cut into the bottom of the filtration chamber 2 to a thickness of about 5 to 10 millimeters, and the granular activated carbon is poured into the bottom of the filtration chamber 2 so that the activated carbon is filled in the filtration chamber 2. The present invention has a simple structure, low material cost, and has a sufficient function as a practical product. According to the present invention, as shown in FIG. 6, a filtration chamber 2 for forming a bucket 9 with a waterproof sheet or the like and storing activated carbon on the bottom surface
You can also connect. A bag-shaped body made of a thin plastic sheet for containing raw water, or a filter material storage section connected to the lower end of a cylindrical body made of a waterproof sheet, that is,
The simplest way is to store the activator or other filtering material directly in the filtration chamber, and digging of the filtering material can be easily prevented by inserting an open cell sponge near the drain hole. Wrap the filtering material in a bag of water-permeable non-woven fabric, or
It is convenient for replacement and portable if you prepare the one in a water-permeable cartridge. These bags or cartridges are used by inserting them into the filtration chamber as they are.
