Filter type cartridge and water treatment method {Filter type cartridge}

The present invention relates to a structure of a filter for removing harmful components such as impurities and chlorine compounds in treated water in a water treatment. The present invention includes a filter cartridge of the present invention in an intermediate position forming a channel and passes purified water therethrough to remove impurities. It is to provide.

In the filter cartridge of the present application, a hole of 0.3 to 1.0 mm is formed at the top and side of the cartridge, and the treated water reacts with an internal filler such as vitamin C or chitosan, which is filled in the cartridge, and is a component such as chlorine, which is harmful to human skin. It is to provide nutritional purified water by removing the ingredients and nourishing the skin. The upper and the side of the cartridge of the present application is formed with two to ten holes of 0.3 to 1.0 mm, and relates to a filter using a cartridge made of a transparent or translucent material to visually identify the state of use of the internal filling.

In general, each local government is to disinfect the chlorine in the water treatment plant to provide tap water to each household, the chlorine is removed by volatilization into some air during the water purification process or supply to each household However, most of the chlorine remains dissolved in the water, rather than removed, causing a unique chlorine disinfection odor.

When the amount of residual chlorine is high, it acts as a cause of dermatitis and atopic disease in children or people with weak skin, or when the water with high amount of residual chlorine is used, the chlorine content contained in the vapor is very bad for people with weak bronchus or lung. In addition to affecting, it is also known to act as a factor causing a carcinogen called THM (trihalomethane).

Various methods have been used and attempted to remove the residual chlorine, which is harmful to the human body. In one embodiment, a shower device capable of removing residual chlorine by providing a filtration device inside the shower head is known. . However, the shower has a disadvantage in that the removal efficiency of the residual chlorine is inferior and it is difficult to use in a low pressure household due to the water pressure.

As another method for removing residual chlorine components, a filter manufactured by filling vitamin C in the filter is known (Korean Patent Application No. 2001-68335). The filter reveals that the vitamin C removes the chlorine component through the chemical reaction of the following Scheme 1 with respect to the chlorine component contained in the tap water.

Scheme 1

C ₆ H ₈ O ₆ (vitamin) + HOCl (hypochlorous acid) => C ₆ H ₆ O ₆ -H ₂ O + HCl (hydrochloric acid)

In order to slow down the solubility of the vitamin C component due to the rapid inflow of water by the incoming water, the filter can further comprise a poorly soluble chitosan, and solidified by mixing a certain amount of calcium sulfate as a curing agent. Filters are also used. At this time, the solid filter has a problem that the water softening function of the filter is significantly lowered and the service life is shortened when it is installed in the water softener due to the excess calcium sulfate used for solidification.

In FIG. 4, the head part 102, the cylinder part 100 (which also serves as a handle part), and the sprinkling part 103 of the showerhead are not shown separately, but may be detachably connected by screw or bayonet coupling.

 If the water treatment mechanism of the present application will be described in detail again through the presented drawings,

As shown in FIGS. 1 to 3, the water introduced from the water inlet 1 passes through the activated carbon nonwoven fabric 12 to first remove impurities such as particulate matter and green water, and passes through the nonwoven fabric 12. Primary purified water flows between the cylinder part 200 and the cartridge 10 through the filtered water discharge groove 19 by hydraulic pressure, and is formed in the upper and side holes 17 and 17 protruded into the baffle jet plate 16 installed on the upper end of the cartridge. It is introduced into the cartridge through '). At this time, harmful components such as chlorine compounds are reacted with internal fillers containing vitamin C, chitosan, etc. to remove the harmful components and contain functional water containing nutrients such as vitamin or chitosan aloe extract. It is the principle to discharge the functional purified water via the outlet (2) via the hole (17).

The transparent cartridge 10 is a cartridge of a transparent or translucent material made of a synthetic resin material such as polypropylene or ABS resin is used to visually change the state of use of the internal filler 20 in a state in which it is mounted in a bathtub, a basin, a water purifier, a shower, or the like. It can be used to easily identify and recognize the need for refilling.

In particular, when the internal filler 20 is a powder, in order to be difficult to determine the replacement time of the filter by changing the powder to a gel state, the ceramic ball together with the internal filler 20 inside the transparent cartridge 10 ( By including 1 to 5 21, it is possible to easily distinguish the gel state and the water (liquid) state to determine the replacement time of the filter.

The holes 17 and 17 'formed at the top or side of the cartridge may vary depending on the purpose of use and the size of the cartridge in order to allow the filter internal filler 20 to be discharged slowly while being less affected by the water pressure. When treating the tap water used in the diameter of the hole is 0.3 to 1.0 mm, according to the dissolution rate of the inner filler 20 can be made by the number of 2 to 10 holes 33 to adjust the dissolution rate. When the diameter of the hole 17 is less than 0.3 mm and the number of holes is 2 or less, the inflow and outflow of water is not easy, and when the diameter exceeds 1.0 mm or the number of holes is 10 or more, the inside filled in the cartridge Fill 20 dissolves easily in water and is released out of the cartridge more than necessary, eventually reducing filter life.

In addition, the baffle ejection plate of the filter cartridge is characterized in that the circular plate suitable for the cylinder inner diameter is used as it is or oval to adjust the contact time and the outflow rate of the water to be treated and the contents of the cartridge. If the amount of treated metabolic water is low and you want to obtain nutrient water at low speed, use the round plate to contact the entire flow with the filling inside the cartridge. If you want to react, and if you want to increase the flow rate and the flow rate is large, the elliptical plate can be used to bypass some of them.

In the above drawings, the internal filler 20 is described as a mixed composition of vitamin C and chitosan powder, but as the second embodiment of the filter cartridge of the present invention, the internal filler 20 adds vitamin C and chitosan powder or ceramic balls. It can be applied in the same manner as in the first embodiment, except that the solid body prepared by compression molding with a conventional press is inserted into the transparent cartridge 10.

In addition, the solid produced by compression molding the powder can be changed in various shapes in the form of a rod, spherical, polygonal or rod and round according to the use, and inserting the prepared solid into the cartridge Since the filter cartridge can be manufactured in a convenient form, the manufacturing process is simple. In particular, the internal fillers may have the advantages of slow elution and ease of refilling of vitamin C due to solids.

The filter cartridge of the present invention is filled with vitamin C and chitosan powder or a solid compacted by pressing the powder into the cartridge, so that there is no mutual reaction between the contents before water is introduced into the cartridge, so that it can be stored for a long time.

By using only vitamin C and chitosan composition inside the cartridge and not using a separate hardener, it is useful as a pretreatment filter, bidet filter, faucet filter, and lotion filter of water softener without deteriorating softening function by hardener.

Including a ceramic ball inside the cartridge provides a filter-type cartridge structure that provides the convenience of identifying the filter replacement time,

The lower and upper cartridges are made of different diameters so that the lower part has a diameter that is in close contact with the cylinder. The upper part forms a flow path between the cylinder and the cartridge, but the upper flow path is installed on the top of the cartridge. Through the openings in the top and side of the cartridge, it enters the cartridge and makes contact with the internal fillings of the cartridge. It provides a water treatment method that reacts to remove harmful substances and to contain and release useful substances.

A cartridge applying the invention of the present invention to a general domestic shower, for example, is used by injection molding the cartridge shown in FIG. 1 so as to be suitable for the inner diameter of a shower having a certain model specification, and is used in the cartridge for vitamin C and chitosan powder. , A mixture of green tea extract, aloe extract, and 1 to 3 ceramic balls are mixed into the cartridge, and the solid molded product is filled into the cartridge and refilled the internal filler after a certain period of time.
