Description

Porous filter and manufacturing process thereof {Porous filter and manufacturing process of the same}

1 is a perspective view showing a first application embodiment of the porous filter according to the present invention,

Figure 2 is a perspective view showing a second application embodiment of the porous filter according to the present invention.

The present invention relates to a porous filter, and more particularly, to a porous filter for filtering impurities contained in water and water softening.

Generally, the water currently supplied for home use is tap water or groundwater. Such tap water or groundwater is often exposed to various pollutants such as heavy metals due to the aging of water supply pipes leading to each household or water pollution. In particular, tap water often has a disinfecting odor due to chlorine components used to sterilize various harmful bacteria during the tap water purification process.

In addition, water currently supplied to homes often contains ionized minerals such as calcium and magnesium. Water containing a large amount of calcium ions or magnesium ions is generally called hard water. In the case of such fresh water, when drinking for a long time, it may cause abdominal pain and diarrhea. Reaction reacts with the precipitate, which can prevent soaps or detergents from functioning. In addition, when the hard water is used to operate the boiler, sediments generated at high temperatures accumulate in the pipe walls, which may cause a decrease in the efficiency of the boiler.

Hard water can also be divided into temporary hard water and permanent hard water. In the case of temporary hard water, heating causes thermal decomposition to produce precipitates containing calcium and magnesium ions, resulting in lower calcium and magnesium ions remaining in the water. Will change to However, in the case of permanently hard water, even more complicated chemical treatment is required to change it into sweet water because it does not turn into a sweet water even when heated.

Conventionally, many kinds of water purifiers have been developed for facilitating the use of tap water or ground water. However, since these functions are inclined to remove contaminants remaining in the water, the ions of light components remaining in the water are removed. It was necessary to soften water so that it could be easily removed and used in real life.

An object of the present invention is to provide a porous filter that can supply water that is easy to use in real life by purifying and softening contaminants remaining in water through a simple configuration. .

Porous filter according to the present invention for achieving the above object comprises a zeolite of 200 to 300 mesh, tourmaline and charcoal, it is preferable that the caustic soda or silicon powder is further provided.

Each component is 80 to 120 parts by weight (wt%) of tourmaline, 20 to 50 parts by weight (wt%) of charcoal, 90 to 100 parts by weight (wt%) of caustic soda, and silicon powder based on 100 parts by weight of zeolite (wt%). 20-50 parts by weight (wt%) are mixed and the mixture is calcined to form a porous filter.

The porous filter is provided with tourmaline powder 80 to 120, charcoal 20 to 50, caustic soda 90 to 100, and silicon powder to 20 to 50 parts by weight (wt%) based on 100 parts by weight of the zeolite powder. A dissolving step of mixing silicon powder and dissolving at 1200 to 1400 ° C., and concentrating the mixture dissolved in the dissolving step at high temperature to form a concentrate by filtration at a high temperature in a liquid state. A mixing step of mixing the tourmaline, zeolite and charcoal in water, a molding step of compression molding the mixture mixed in the mixing step, and a firing step of firing the molded product compressed in the molding step at 850 to 950 ° C. It is preferably formed through a series of steps.

Hereinafter, the porous filter according to the present invention will be described in detail.

The porous filter according to the present invention is formed through a series of processes as follows.

Phase 1-Raw Material Preparation

The raw materials used to make the porous filter are zeolite, tourmaline, charcoal, caustic soda and silicon powder. Each raw material is 80 to 120 parts by weight (wt%) of tourmaline, 20 to 50 parts by weight (wt%) of charcoal, 90 to 100 parts by weight (wt%), silicon powder, based on 100 parts by weight of zeolite (wt%). 20 to 50 parts by weight (wt%) are prepared respectively.

Zeolites, also called zeolites, are of various kinds but have a high water content and have properties in common with the nature of crystals and acids. The bond of each atom is loosely crystallized structurally, and even though the moisture filling the space is released at high heat, the skeleton remains the same, so other fine substances can be adsorbed, and thus it is widely used as an adsorbent.

Tourmaline is a complex rod silicate of iron, magnesium, alkali metals and aluminum. Electricity is generated by friction, and it is also called tourmaline because both ends are charged positively and negatively when heated. The use of tourmaline in water is known to make the water slightly alkaline, rich in minerals and, in particular, tap water, which eliminates the chlorine odor used for disinfection. In addition, it is known that the use of water whose properties have been changed by tourmaline is excellent for moisturizing the skin, relieving the symptoms of skin diseases such as atopy, and regenerating and purifying skin cells. Therefore, tourmaline is excellent for softening and purifying tap water. It is known to have a functioning substance.

Silicon powder acts as a binder in the molding process of the porous filter, and caustic soda is used as a melting catalyst when melting the silicon powder. When the content of caustic soda is low, the melting time of the silicon powder is increased. On the contrary, when the content of caustic soda is too high, bubbles are generated when the silicon powder is melted. Therefore, it is very important to maintain the content of caustic soda at an appropriate level. .

Charcoal is added to form pores in the porous filter and forms pores inside and outside while leaving the molding by combining with oxygen during the firing step described later.

Second Step-Dissolution Step

Caustic soda and silicon powder in the prepared raw materials are mixed and dissolved at 1200 ~ 1400 ℃.

Stage 3-Concentration

The mixture of hot caustic soda and silicon powder dissolved in the dissolution step is filtered to remove impurities in a high temperature state and concentrated to a liquid state to form a concentrate.

Step 4-Mixing Step

In the mixing step, the tourmaline, zeolite and charcoal are mixed with the concentrate concentrated in the concentration step.

Step 5-forming step

In the molding step, the mixture mixed in the mixing step is compression molded into a desired shape, and may be molded to have various shapes and sizes according to the purpose of use of the porous filter and the installation location or mechanism.

6th step-firing step

The molded article compressed in the molding step is completed as a product through a sintering step of firing at 850 ~ 950 ℃, in which the char is combined with oxygen is released from the molding, in this process a plurality of fine pores in the molding Is formed.

Porous filters formed through the same method as described above can be used to purify and soften the water supplied to the home.

As shown in FIG. 1, a filter including a porous filter between a main supply pipe 11 of household water supplied to a home and a branch pipe 12 connected to a toilet, a kitchen, a boiler room, etc. from the main supply pipe 11. By installing the box 10, the contaminants may be purified and softened in the course of passing the household water supplied from the main supply pipe 11 through the filter box 10.

Alternatively, as shown in FIG. 2, the porous filter may be directly installed in the shower 20. The water introduced into the shower body 21 through the hose 24 is purified and softened while passing through the filter part 22 including the porous filter before being discharged through the discharge part 23. In the present embodiment, the shower 20 is shown, but in addition, it may be installed in a kitchen, a boiler room, a sink, or the like so that the water may be purified and softened before being discharged to the user.
