Description

Ion Exchange Resin Tank Structure {THE STRUCTURE OF ION-EXCHANGE RESIN TANK}

The present invention relates to an ion exchange resin tank structure, and more particularly, raw water introduced into the lower part of the storage compartment may be converted into soft water in the storage compartment and discharged through the lower compartment again, thereby facilitating the storage compartment of the ion exchange resin tank. It is to provide an ion exchange resin tank structure that can be easily removable.

Currently, water softeners installed in homes or offices have a basic function of chemically converting hard water ions contained in tap water into softened water.

In general, tap water (hard water) contains a large amount of chlorine used in the purification process, and also contains various heavy metals (ions) such as iron, zinc, lead, and mercury, which are harmful to humans due to deteriorated pipes and water pollution. . Such tap water is not fatal to the human body, but when used as it is when washing the skin, the metal ions contained in the water and the fatty acids of the soap are combined to make a metallic foreign substance. It causes skin diseases or accelerates aging of the skin.

Therefore, in order to prevent this, a water softener is developed to pass the tap water through the Na + type strong acid cation exchange resin to exchange the hardness components Ca2 + and Mg2 + with Na + in the resin to make soft water, which is mainly used for cleaning. .

The water softener has the principle of softening by replacing calcium ions and magnesium ions contained in hard water with sodium ions (Na +). For this purpose, a soft water container containing an ion exchange resin of a special high molecular compound containing sodium ions is an essential component. And a regeneration vessel containing ion exchange resin regenerators such as salt which, when dissolved in water, produces sodium ions.

That is, the water softener continuously generates tap water by contacting the ion exchange resin by continuously passing tap water into the soft water container in a state where a large number of fine ball-shaped ion exchange resins are stored in the soft water container. Since Na + is greatly reduced by continuous contact with tap water, salt water consisting of NaCl component is introduced into the soft water tank in order to preserve it.

Conventional water softeners are generally filled with a soft water tank including an ion exchange resin for converting raw water supplied from the outside into soft water, and filled with salt for supplying regeneration water for regenerating the ion exchange resin when the performance of the ion exchange resin is degraded. It is equipped with a recycling container.

In spite of the regeneration treatment, the ion exchange resin has a problem in that performance decreases depending on the amount of usage due to aging and crushing of the ion exchange resin itself, contamination by foreign matters, etc. over time. In addition, when a plurality of soft water tanks are used, when the amount of ion exchange resins in one soft water tank is small, the performance is degraded early due to relatively more frequent regeneration and a large amount of water flow than a tank having a large amount of ion exchange resins. There is this.

However, conventionally, there is a problem in that the replacement of the ion exchange resin in the soft water container is not easy, and therefore, the ion exchange resin whose performance is degraded must be continuously used.

On the other hand, in the past, when the raw water falls into the soft water tank, it does not spread widely throughout the soft water tank, but falls directly to the bottom of the soft water tank to form a thick stream of water. Ion resin of shows the shape of the channel (C) recessed into.

In order to prevent this, the distribution plate is provided in the part where the raw water falls, but these conventional distribution plates are structurally complicated and separate from the mesh network, which causes a complicated water softener structure and an increase in production cost.

The present invention has been made to solve the above-described problems, an object of the present invention, raw water introduced into the storage compartment can be converted into soft water in the storage compartment and discharged again through the storage compartment bottom, thereby It is to provide an ion exchange resin tank structure that can easily detach the storage compartment.
