Abstract

The present invention relates to a continuous pool water purifier which efficiently purifies contaminated water in a swimming pool into clean water that is not harmful to a human body, in a short period of time. The pool water purifier disclosed in prior art has a filter unit that needs to be taken out to the outside to be directly cleaned or maintained and repaired; has an ozone treatment unit with a complicated structure and high equipment cost; and conducts ozone treatment on water only once, thereby exhibiting reduced sterilizing effects in spite of the expensive equipment cost. In order to eliminate these problems, the continuous pool water purifier of the present invention enables a micro filter unit detachably installed inside a first filtration tank to be extracted to the outside to be directly cleaned; allows only the vertical drum screen part of the micro filter unit to be replaced; and sterilizes purified water which is filtered for a first time by an ozone spray nozzle and again sterilizes the water which is filtered for a second time by using a UV sterilizer.

Description

{Continuous pool water purifier}

The present invention relates to a novel concept of supplying polluted water of a swimming pool in a short period of time in a clean water which does not harm the human body efficiently.

In general, swimming pools are used jointly by several people, and pools contain chemicals such as body oil, suntan lotion, impurities such as manure, foreign bodies such as swimmer's hair, or organic / inorganic The accumulation of very high concentration of dirt in the reaction with the flocculant causes a serious deterioration in the cleanliness of the water quality as well as the contamination due to the corruption of the material. Therefore, the water quality control .

Previously, for filtration, circulation filtration was carried out until the closing time after the opening of the swimming pool. During the filtration, water was introduced into the upper layer by filtration through an upstream downflow filtration, passed through several layers of filter media, impurities were filtered from the upper portion, Water is reintroduced into the swimming pool, and during long-time filtration, impurities are filtered from the inside of the filter to lower the filtration ability, so that backwashing and washing are performed to regenerate the filtration ability.

As a prior art document for purifying polluted water in such a pool, "Patent Registration No. 1056048, name / swimming pool water purification system" is disclosed.

The prior art filtration apparatus periodically supplies a coating material for filtering without having to replace the filter unit and can be used semi-permanently as the precoated coating material is removed from the filter member through backwashing. By increasing the rate of water disinfection, the dependence of disinfection on the chemical treatment section is lowered, so that the damage caused by the purified water can be minimized.

The prior art filtration apparatus has a limitation in removing the coating material only through backwashing, and it is most preferable to directly draw out the filter unit to perform a direct cleaning or maintenance.

In addition, since the ozone treatment unit has a complicated structure including an ozone generating unit, an ozone mixing unit, an ozone reaction tank, and an ozone removing unit, the ozone treatment unit has a complicated structure and an extremely high equipment cost. There is a problem that the sterilizing effect is lowered.

In order to solve the above-mentioned problem, the present invention provides a microfilter unit detachably installed in a primary filtration tank to be directly drawn out to the outside, so that only a vertical drum screen can be partially replaced in the microfilter unit Technology.

The present invention also provides a technique for primarily sterilizing purified water that is primarily filtered by an ozone spray nozzle installed in a water supply pipe connected between a plurality of primary filtration tanks.

In addition, the present invention provides a technique for directly removing a horizontal drum screen detachably installed in a secondary filtration tank and directly washing the activated carbon in the horizontal drum screen.

A technique for sterilizing the secondary water filtered by the ultraviolet sterilizer installed in the secondary filtration tank and easily replacing the ultraviolet lamp from the outside is proposed.

According to the present invention, the microfilter unit installed inside the primary filtration tank is directly drawn out to be directly cleaned, thereby being excellent in cleaning efficiency and reusable. Further, the microfilter unit can be reused, It provides the effect of drastically reducing the maintenance cost by replacing only the screen.

In addition, the present invention is characterized in that the primary filtered water is primarily sterilized by using an ozone spray nozzle, and the secondary filtered water is sterilized by secondary sterilization using an ultraviolet sterilizer, The structure of the ozone spray nozzle and the ultraviolet sterilizer is very simple, and the miniaturization is realized, so that the equipment cost is very low, a separate occupation space is not required, and it is economical and provides an effect of maximizing the utilization of the space around .

Furthermore, the ultraviolet sterilizer can open the lamp housing from the outside to easily replace the ultraviolet lamp, thus providing excellent operability and convenience of maintenance.

In addition, since the horizontal type drum screen installed inside the secondary filtration tank is directly drawn out to directly wash it, the cleaning efficiency is excellent as well as reusable. Also, only the activated carbon having the end of life can be replaced Thereby significantly reducing the maintenance cost.
