The present invention relates to a simple tap water tank with a built-in filter, in particular, installed so that the filter is integrally embedded in a stainless steel cylindrical water tank, the filter medium filled in the filter is automatically drained by a backwashing process to replace the filter medium The present invention relates to a simple tap water tank that extends the cycle and facilitates the discharge of pollutants.

In general, simple water supply for farming and fishing villages is mostly stored as raw water of natural water and groundwater without additional filtration and water purification facilities, and is stored and supplied to the farmland in each home or outdoor area.

Conventional water tanks are formed in a rectangular or cylindrical shape. In the case of a rectangular water tank, a cylindrical water tank is preferred because it is difficult to clean the interior because support and reinforcing structures are required inside. It is preferable to employ a material.

 By the way, the conventional simple tap water tank has no filtration facilities, but even if there is no filtration facilities, it is to be made on the supply path of raw water or flat pipe of the plain, so that the cost of filtration treatment is burdensome, and the filtered water is transferred to the drainage basin. In case of contamination of water pipe, there was no way.

Therefore, the water quality due to contaminants is frequently contaminated during the storage of raw water on the side of the water tank adjacent to the drainage, which is because most water tanks store raw water as it is, despite its form and material. Sand and colloidal suspensions and other organic dissolved substances contained in raw water were stored in the tanks as they were, causing the water pollution in the tanks.

In order to overcome this problem, a water tank with a filtration system is required. However, in the case of a filtration facility using a filter medium such as activated carbon and sand, which is commonly used as a filter medium, it is difficult to insert, discharge, and replace the filter sand. It is a situation that cannot be used due to a difficult problem to replace.

However, the Republic of Korea Utility Model Registration No. 0271280 has three cylindrical partitions on the same side as the cylindrical water tank with multiple bulkheads so that only the supernatant can overflow to the inside. Because it is temporarily stored while being passed, there is a problem that the floating material is moved out to the inside as it is.

On the other hand, another example of the conventional water tank for liver abnormality tap water, as disclosed in the Republic of Korea Patent Registration No. 475597 "Stainless liver water tank for liver abnormality tap water", the insulating material is installed to the outside of the housing and the water in the tank is discharged to the outside As the filter tank is detachably installed in the discharge pipe, there is provided a precipitation type filtration apparatus for depositing impurities and foreign substances in the filter tank to discharge the sludge to the outside.

At this time, although the filter medium is filled in the filter tank, when contaminants are attached to the filter medium, simply discharging only the sludge accumulated in the lower part may not function properly, and the replacement of the filter medium may not be good. Winter filtration tanks were exposed to the outside, there was a fear of freezing.

In addition, the existing simple tap water tank has to periodically clean the inner surface of the tank due to foreign substances or impurities in the raw water (about 6 months), so that the worker has to enter and clean the tank directly. There was this.

The present invention has been proposed to solve the above problems in view of the above problems, the purpose of which consists of a filter in which the filter medium is laminated in the drainage water tank, and the input and discharge of the filter medium is easy, and the replacement of the filter medium and water It is to provide a simple tap water tank with a built-in filter to extend the cleaning cycle of the tank.
