Abstract

PURPOSE:To reduce the installation space of a water purification device and purify a contaminated water economically by a method wherein the water purified in each of purification cartridges is collected for sending as a clean water. CONSTITUTION:A contaminated water is supplied from a water feed pipe 1 into each of a plurality of purification cartridgers 4, through which this water is filtered. The water thus purified is collected for discharge from a water supply pipe 9. To clean the inside of the purification cartridge 4, a clean water is supplied thereinto from the water supply pipe 9 and this clean water is made to flow backward inside the purification cartridge 4 and discharged from the water feed pipe 1. In this way, the substances adhered to a filter 15 are separated therefrom for discharge to clean the inside of each purification cartridge 4.

Recently, due to the influence of the fitness boom, many people are taking up swimming as a full-body exercise that is most suitable for improving health and relieving stress, and many people of all ages enjoy swimming pools. It has become. Accordingly, the number of swimming pools is increasing from public ones to privately run ones such as sports clubs.

Along with this, there is a growing interest in the sanitary conditions of swimming pools, especially water purification equipment that determines water quality. This is especially common in heated pools, where bacteria breed in the pool water, or when human sweat, urine, feces, spittle, hair, etc. mix in, causing the pool water to become contaminated and the water quality to deteriorate. It is something.

Conventionally, the most basic method for purifying pool water is a so-called pool water filtration method and its device, and activated carbon, ceramic filters, etc. are used as filter media for the filtration method. In addition to chlorine sterilization,
Ultraviolet sterilization, ozone sterilization, etc. are carried out in parallel.

However, according to the conventional water purification method and device described above, in order to efficiently purify pool water, the filtration device is large and its installation requires a vast space and a large amount of cost. Therefore, it can be said that it is economically burdensome and inappropriate as a purification device for use in private swimming pools.

Therefore, various types of convenient equipment such as water purification tanks have been provided for purifying pool water, but it is no exaggeration to say that there are still not enough of them. Therefore, how to easily and economically solve the contamination of pool water, which increases in proportion to the increased use of pools, has become an important management issue for pool management. There is.

1 back plate Next, embodiments of the present invention will be described based on the drawings.

As shown in Fig. 1, a water supply pipe 1 led from a pool is connected to a tank 2 consisting of a thin box-like body with a predetermined area and a valve 3.
A plurality of purification cartridges 4 are erected on the upper surface of the tank 2 and removably connected with nuts 5, and approximately in the middle of the purification cartridges 4 are connected to the tank 2. Tanks 6 having substantially the same configuration are connected by a clean water stopper 7 and a nut 8, and a water pipe 9 is connected to the tanks 6 through a valve 10 so as to be communicable.

The purification cartridge 4 has a rectangular or circular shape, and its interior has water repellent portions 11 at the lower and approximately middle portions.
．． The lower purification chamber 12 and the upper purification chamber 13 are separated by lla.
It is divided into two parts.

A valve 14 is interposed between the lower purification chamber 12 and the water retarding section 10, and a porous filter 15 is provided in the center in the axial direction, the upper end of which is brought into close contact with the water passage port 16 communicating with the water retarding section 11. Further, it is suspended from a partition wall 19 by a rod 18 whose lower end is connected to a cap 17. The porous filter 15 is a cylindrical body made of a ceramic filter medium, and the upper end of the cylindrical body is connected to the water retarding section 1.
1 and has diatomaceous earth 20 applied to its outer peripheral surface. On the other hand, in the upper purification chamber 13, a water inlet 23 is formed in the partition wall 21 forming the water retarding section 11 and communicates with the water inlet 23 via a valve 22, and the lower end of the cylinder 24 is brought into close contact with the water inlet 23 so as to be able to communicate therewith. They are connected upright in the axial direction, and their upper ends are opened into the upper purification chamber 13. The cylinder body 24 is made of a rectangular cylinder or a cylinder, and a glass tube 25 is inserted into its upper end.The glass tube 25 is inserted in the axial direction from the upper end of the purification cartridge 4, and the air supply pipe 2 is inserted into the inside thereof.
6 and an ultraviolet germicidal lamp 27 are suspended and inserted. In addition, an open hole 28 is provided at the upper end of the upper purification chamber 13 so that the air inside can be removed.
and the air supply pipe 30 is inserted, and the air supply pipe 30 is inserted into the cylinder body 2.
It has entered the bottom of 4. The air supply pipe 30 supplies air and ozone, either alone or in a mixture of qt, into the cylinder body 24.

To explain the operation of the above embodiment, as shown in FIG. 2, when contaminated pool water is supplied from the water supply pipe 1, the pool water flows into the tank 2 and enters the water retarding section 11.
It flows into the lower purification chamber 13 via the valve 14. In the lower purification chamber 12, the pool water flows into the porous filter 1 due to its pressure.
5, and at that time, due to diatom ±20 and ceramic,
Contaminants mixed into the water are filtered out. The water that has entered the porous filter 15 then directly enters the cylindrical body 24 in the upper purification chamber 13 via the valve 22. Therefore, cylinder body 2
4, it is further sterilized by an ultraviolet germicidal lamp 27 in a glass tube 25, and falls from the top of the cylinder 24 onto activated carbon 29. The activated carbon 29 removes organic substances contained in water and removes odors and the like. The purified water thus reaches the inside of the tank 6 via the water retardation section 11a, and is returned from the tank 6 via the water pipe 9 to the pool.

Note that, before performing the above-mentioned purification, it is desirable that the pool water supplied from the water supply pipe 1 be purified to some extent in advance by a filtration process to remove bulky debris such as hair and other lumps.

When filtered pollutants adhere to the outer peripheral surface of the porous filter 15 in the purification cartridge 4 and the filtration rate decreases, clean water is removed from the water pipe 9 as shown in FIG. The water is fed under pressure from the retarding section 11a to the inside of the porous filter 1.
5 and ejected into the lower purification chamber 12. Therefore, the pollutants adhering to the outer peripheral surface of the porous filter 15 can be peeled off from the surface, enter the tank 2 from the water retardation section 11 via the valve 14, and be discharged to the outside from the water supply pipe 1. .

When one of the purification cartridges 4 reaches the end of its service life or becomes unusable due to damage, etc., in order to stop using that purification cartridge 4, the valve 14 is closed to stop the water supply, or the purification cartridge 4 is stopped. Replace the cartridge 4 itself. When replacing, water supply pipe 1 and water supply pipe 9
Close the comrade valves 14 and 22 respectively and open the tank 2.
．． 6, remove the purification cartridge 4 as shown in Fig. 4, attach a new purification cartridge to the removed part, supply water to the tank 2 again, and perform purification in the same manner as above. Continues its action.
