Description

Cycling apparatus for softner

The present invention relates to a circulator of the water softener in which the raw water and the ion exchange resin are circulated in the vertical direction in the water softener in which the raw water is introduced into the lower side of the ion exchange vessel and discharged to the upper side. A suction hole is placed in the jaw portion of the reducing pipe which is connected in the direction, and the ion exchange resin is sucked into the reducing pipe by the flow rate of the raw water passing through the reducing pipe, and the up and down direction in the ion exchange container is increased. The present invention relates to a circulation device for a water softener, which facilitates an ion exchange action by circulating, and has a pretreatment filter at a raw water inlet to help purge.

In general, tap water contains a large amount of chlorine components used in the purification process, and contains a variety of heavy metals (ions) such as iron, lead, zinc, mercury, etc., which are harmful to humans due to deterioration pipes and water pollution.

When the tap water is used as it is when washing the skin, the metal ions contained in the water and the fatty acids of the soap combine to form a metallic foreign substance. When the metallic foreign substance comes into contact with the skin, it causes various skin diseases such as allergies. Or promote aging of the skin.

To prevent this, tap water is passed through Na + type strong acid cation exchange resin, and softener is developed to exchange Ca + 2 and Mg + 2 ions, which are hardness components, with Na + ions in the resin to make soft water. It is becoming.

The conventional water softener such as the upper end portion of the raw water inlet pipe 24 is installed so as to penetrate the center of the ion exchange resin 22 from the bottom surface of the ion exchange vessel 20 as shown in Figure 1 attached to the ion exchange resin It was configured to discharge the soft water 28 through the soft water discharge port 26 located at a position higher than the upper side of (22) above the ion exchange vessel 20.

However, the conventional water softener such as the raw water introduced through the raw water inlet pipe 24 because both the upper end of the raw water inlet pipe 24 and the soft water outlet 26 are located in the upper portion of the ion exchange vessel (20). ) Stayed on the upper portion of the ion exchange resin 22 for a while, and there was a problem that it was immediately discharged through the soft water outlet 26 before the ion exchange action occurred.

That is, in the upper portion of the ion exchange resin 22 located near the upper end of the raw water inlet pipe 24, the ion exchange action is actively performed, but the ion exchange resin is located at a relatively long distance from the raw water inlet pipe 24. In the lower layer of (22), there is a problem that the ion exchange action is biased only in the upper layer of the ion exchange resin 22 because the supply amount of the raw water 29 is low and the flow is weak due to the fluid resistance.

In addition, since the raw water 29 has not been purified and flows into the inside of the ion exchange vessel 20 as it is, there is a problem that foreign matters having a relatively large particle size that cannot be purified by the ion exchange resin 22 are mixed with soft water. There was this.

The present invention has been made to solve the above problems, the object of which is to enable the up and down circulation in the ion exchange resin and the ion exchange vessel of the raw water to make a more even ion exchange action, It is to provide a circulator of the water softener to filter the contained foreign matter before entering the ion exchange vessel.

In order to achieve the object of the present invention, a reducing pipe vertically connected to a raw water inlet located on the bottom surface of the ion exchange vessel is placed vertically so that the diameter of the upper portion is larger than the diameter of the lower portion, A suction hole for circulating the exchange resin in the up and down direction is formed, and a water perforated plate is disposed between the soft water discharge port provided on the upper side of the ion exchange vessel and the upper end of the reducing pipe to filter the ion exchange resin from the soft water. The circulation device of is provided.

On the other hand, it is located between the soft water outlet (44) 46 and the upper end of the reducing pipe (30) (32) provided on the upper side of the ion exchange vessel (40) (42) and ion exchange from the soft water (60) The perforated plate 70, 72 which filters out resin 50, 52 was provided and comprised.

The reducing pipes 30 and 32 consist of the small diameter pipes 30b and 32b on the lower side and the large diameter pipes 30c and 32c on the upper side, and the small diameter pipes 30b and 32b are the large diameter pipes 30c. It is shorter than (32c), a part of the upper end of the small diameter pipe (30b) 32b is introduced into the large diameter pipe (30c) (32c), the outer peripheral surface of the small diameter pipe (30b) 32b and the large diameter pipe (30c) ( A plurality of ribs 80, 81, 82, 83 are provided on the inner circumferential surface of 32c.

That is, a part of the upper end of the small diameter pipes 30b and 32b enters into the lower end of the large diameter pipes 30c and 32c, and connects the small diameter pipes 30b and 32b to the large diameter pipes 30c and 32c. The ribs 80, 81, 82, and 83 are formed of thin steel plates, and are vertically installed so as not to disturb the flow of the fluid.

The pretreatment filters 90 and 92 are installed on the flow paths flowing into the raw water inlets 40a and 42a to filter out foreign substances contained in the raw water 65. The diaphragm 90a, 92a is installed in the inside to extend the flow path.

In addition, the soft water discharge pipe 104, 106 for discharging the soft water 60 is installed on the side of the soft water discharge port (44, 46), the ion exchange containers (40, 42) to use hot and cold water The two are organized into a pair.

In addition, between the pretreatment filter 90 (92) and the soft water discharge pipe (104) (106), a four-port two-switched switching valve (130) 132 is provided so that the flow path can be switched or opened and closed.

In the drawings, reference numerals 100 and 102 denote the raw water supply hoses coupled to the lower ends of the pretreatment filters 90 and 92 to supply the raw water 65, and 110 and 112 to open and close the upper ends of the soft water outlets 44 and 46. One-touch cap is shown, 120 is a discharge faucet, 150 is a case surrounding the outside of the ion exchange vessel (40, 42).

Hereinafter, the operation according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in Figs. 2 to 6, when both or one of the switching valves 130 and 132 are switched to open the flow passage to the raw water supply hose 100 and 102, the raw water 65 is The raw water supply hoses 100 and 102 and the pretreatment filters 90 and 92 are supplied to the reducing pipes 30 and 32 installed in the ion exchange vessels 40 and 42.

At this time, the raw water 65 is primarily filtered by the relatively large particles contained in the raw water 65 by the pre-treatment filter (90, 92), the small constituting the reducing pipe (30, 32) As the raw water 65 rises vertically through the landscape 30b, 32b and the large diameter tube 30c, 32c, the upper layer of the ion exchange vessels 40, 42 through the upper end of the large diameter tube 30c, 32c.
