Manufacturing method of deodorization using mineral {manufacturing method of composition for deodorization using mineral}

The present invention relates to a method for manufacturing a deodorant using a mineral, and more particularly, to a method for manufacturing a deodorant that can be safely used because it is not harmful to the human body and has excellent deodorizing effect using mineral powder.

In general, various types of antibacterial and deodorizing agents for antibacterial and deodorizing are commercialized and used. Antibacterial and deodorizing agents are used not only for home use, but also throughout industries such as beauty, environmental, food, health products, livestock, and industrial fields. In particular, in recent years, it is also widely used for quarantine, disinfection, and space sterilization.

In the case of offices or houses, various microorganisms such as bacteria, fungi, pathogenic bacteria, and fungi proliferate in corners, wardrobes, shoe cabinets, under beds, etc. where humidity and temperature conditions are suitable because nutrients are abundant for bacteria to ingest. This causes allergic diseases such as respiratory diseases, itching, rashes, or odors.

Various organic or inorganic synthetic antibacterial and deodorizing agents for suppressing the growth of microorganisms and removing odors have been developed. A method for preparing an antibacterial agent by synthesizing chemicals is disclosed in Korean Patent Registration No. 10-1180117. However, antibacterial deodorant synthesized with chemicals may cause harmful side effects to the human body such as respiratory disease, itching, rash, etc., and in particular, there is a problem that can damage the skin when in direct contact with the skin.

On the other hand, antibacterial and deodorizing agents that are widely used are representative of Rox, a chlorine-based disinfectant. Rox exhibits strong antibacterial power because it exerts antibacterial and deodorizing effects by oxygen generated from hypochlorous acid (HClO), but occurs when used. Due to the toxicity of chlorine gas, which gives users discomfort and anxiety about human safety, they tend to be reluctant to use it in indoor spaces including kitchens and kitchens.

Republic of Korea Patent Registration No. 10-2179548 discloses a method for preparing a liquid composition for antibacterial and deodorant use using minerals.

The antibacterial and deodorizing composition has the advantage of not being harmful to the human body compared to antibacterial and deodorizing agents made of chemicals while having antibacterial and deodorizing effects. However, since fine mineral powders are mixed in the supernatant obtained by solid-liquid separation through precipitation, the liquid composition has a problem in that discoloration due to minerals occurs over time.

Let's look at each step.

1. Mixing step

Prepare materials to obtain mineral powder. As materials, ocher powder, illite powder, zeolite powder, elvan powder, bentonite powder, diatomaceous earth powder, and calcium powder are used.

Ocher powder is obtained by pulverizing ocher to a particle size of 100 to 300 mesh.

Loess contains calcium carbonate (CaCO ₃ ), silica (SiO ₂ ), alumina (Al ₂ O ₃ ), iron, magnesium (Mg), sodium (Na), potassium (K ₂ O), etc., mainly 0.05~0.01 It is a yellow mineral composed of millimeter silt particles. Ocher emits far-infrared rays, has excellent sterilization effect and toxic removal ability, is excellent in neutralizing harmful substances, and has excellent deodorizing ability with its unique honeycomb structure.

Illite powder is obtained by grinding illite to a particle size of 100 to 300 mesh.

Illite is a mineral that is common in sedimentary rocks or hydrothermal rocks and occupies a very important position along with kaolin minerals and smectite. Components of illite include SiO ₂ , Al ₂ O ₃ , K ₂ O, Na ₂ O and the like. Illite is a mineral material that emits far-infrared rays, is safe for the human body, and has a deodorizing effect in addition to physiological effects on cells.

Zeolite powder is obtained by grinding zeolite to a particle size of 100 to 300 mesh.

Zeolite is an inorganic substance that causes an ion exchange reaction, and belongs to the zeolite group in mineralogy as a mineral with remarkable ion exchange ability in nature. Zeolite has excellent deodorization and antibacterial power along with far-infrared radiation, so it removes various bad odors and purifies indoor air. As such zeolite, natural ore stones may be used, but artificially synthesized zeolites may be used.

Elvan powder is obtained by grinding elvan to a particle size of 100 to 300 mesh.

Elvan is a semi-intrusive rock belonging to quartz porphyry and feldspar porphyry. Its composition varies depending on the region, and its main components are alkali feldspar and quartz. has a character These elvans have the ability to adsorb and filter harmful components due to their porosity, to adsorb heavy metals through the ion exchange ability of alkali metals, to relatively elute alkali ions, to emit far-infrared rays, and to deodorize.

Bentonite powder is obtained by grinding bentonite to a particle size of 100 to 300 mesh.

Bentonite is a clay mineral of the montmorillonite family, and has the characteristic of being viscous when moisture is added and being hardened and sintered during drying and firing. Bentonite is a very viscous material created by the decomposition of glass components of volcanic ash. In particular, it has excellent cation exchangeability and generally contains components such as quartz, zeolite, and feldspar.

Diatomaceous earth powder is obtained by grinding diatomaceous earth to a particle size of 100 to 300 mesh.

Diatomite is a rock or sediment formed by the accumulation of the remains of diatoms, which are single-celled organisms, after they die. Diatoms are microscopic organisms that live in lakes and seas, and their skeletal components are mainly composed of silicic acid (SiO ₂ ). Since diatomaceous earth has a porous structure with countless pores, the deodorizing effect can be greatly enhanced by adding diatomaceous earth.

Calcium powder is obtained by pulverizing a calcium mineral containing calcium into a particle size of 100 to 300 mesh. Examples of calcium minerals include calcite, plagioclase, and wollastonite.

In addition, calcium powder may be used as a shell. The shell has excellent deodorizing effect due to excellent physical adsorption due to high specific surface area and chemical adsorption by Ca component that accounts for most of the components. Oyster shells can be used as shells.

When the above materials are prepared, they are evenly mixed to obtain mineral powder. For example, 40 to 100 parts by weight of illite powder, 30 to 70 parts by weight of zeolite powder, 20 to 40 parts by weight of elvan powder, 10 to 20 parts by weight of bentonite powder, 10 to 20 parts by weight of diatomaceous earth powder, Mineral powder is obtained by mixing 10 to 20 parts by weight of calcium powder.

2. Liquid Agitation Step

Next, after adding the mineral powder to the water, it is stirred. At this time, 2 to 10 parts by weight of mineral powder may be added to 100 parts by weight of water.

After adding the mineral powder to the water, the mineral powder can be uniformly dispersed in the water by stirring for 2 to 6 hours.

Stirring of water and mineral powder can be performed using an agitator. An example of an agitator is shown in FIG. 2 .

Referring to FIG. 2, the stirrer 10 includes a stirring tank 11, a rotating shaft 20 vertically penetrating the stirring tank 11, a driving unit 30 for rotating the rotating shaft 20, and a rotating shaft ( 20) formed to be spirally wound on the lower outer circumferential surface to form an upward flow, and spirally formed on the upper outer circumferential surface of the rotating shaft 20 to be wound in the opposite direction to the lower spiral blade 41 The upper spiral blades 45 forming a downward flow, the stirring blades 50 installed in the center of the rotating shaft 20 so as to be located between the lower spiral blades 41 and the upper spiral blades 45, and the stirring tank It is installed in (11) and has a supernatant discharge pipe 15 for discharging supernatant to the outside.

The stirring tank 11 has a cylindrical structure.

A water supply pipe 11 through which water is supplied is connected to the top of the stirring tank 11 . Water stored in the water tank flows into the agitation tank 11 through the water supply pipe 11 . In addition, a mineral storage hopper 13 is installed on the top of the stirring tank 11 to input the mineral powder into the stirring tank 13. A certain amount of mineral powder is injected into the stirring tank 11 through the mineral storage hopper 13 .

In addition, a supernatant discharge pipe 15 and a drain pipe 17 are further installed in the stirring tank 11. The supernatant discharge pipe 15 is installed on the side of the stirring tank 11. The supernatant discharge pipe 15 is installed at a position spaced a certain distance from the bottom of the stirring tank 11. The supernatant separated from the solids may be discharged to the outside of the stirring tank 11 through the supernatant discharge pipe 15 .

The drain pipe 17 is installed under the stirring tank 11. Precipitated solids may be discharged to the outside of the stirring tank 11 through the drain pipe 17 .

The rotating shaft 20 is installed to pass through the stirring tank 11 vertically. The rotating shaft 20 is rotatably supported on the stirring tank 11 .

The driving unit 30 includes a motor 31, a driving gear 33 coupled to the driving shaft of the motor 31, and a driven gear 35 coupled to the lower portion of the rotating shaft 20 and meshing with the driving gear 33. provide

A geared motor may be used as the motor 31 . When the motor 31 operates, the rotating shaft 20 rotates at a constant speed.

The lower spiral blades 41 and the upper spiral blades 45 are installed on the rotating shaft 20 with the stirring blades 50 interposed therebetween.

The lower spiral blade 41 is formed in a shape wound around the lower outer circumferential surface of the rotating shaft 20 . The lower spiral blade 41 is formed along a spiral trajectory from the lower part of the rotating shaft 20 to the agitation blade 50. The lower spiral blades 41 form a flow from the bottom to the top when the rotating shaft 20 rotates, that is, upstream. Therefore, the contents located in the lower layer of the stirring tank 11 are moved upward by the lower spiral blades 41.

The upper spiral feathers 45 are formed in a shape wound around the upper outer circumferential surface of the rotating shaft 20. The upper spiral blade 45 is formed along a spiral trajectory from the top of the rotating shaft 20 to the agitation blade 50. The winding direction of the upper spiral blades 45 is opposite to that of the lower spiral blades 41. That is, when the lower spiral blades 41 draw a spiral trajectory wound in a counterclockwise direction, the upper spiral blades 45 draw a spiral trajectory wound in a clockwise direction.

The upper spiral blades 45 form a flow from the top to the bottom when the rotating shaft 20 rotates, that is, a downward flow. Therefore, the contents located on the upper layer of the stirring tank 11 move downward by the upper spiral blade 45.

The stirring blades 50 are located at the center of the rotating shaft 20. The stirring blades 50 are located above the lower spiral blades 41 and below the upper spiral blades 45.

Two stirring blades 50 are provided on the rotation shaft 20 at intervals of 180 degrees. Unlike this, of course, the stirring blades may be provided with three or four.

Each stirring blade 50 is composed of a pair of connecting rods 51 extending horizontally outward from the rotating shaft 20 and a blade 55 coupled to an end of the connecting rod 51.

The stirring blades 50 serve to mix water and mineral powder while rotating. In particular, since the upward flow formed by the lower spiral blades 41 and the downward flow formed by the upper spiral blades 45 collide in the agitation blades 50, a vigorous vortex is formed, so the agitation effect can be greatly increased.

3. Precipitation aging step

Next, while the mixture obtained in the liquid phase stirring step is left still and aged, solids are precipitated.

The precipitation maturation step may be performed in the agitation tank described above. That is, after the liquid phase agitation is completed, the operation of the motor is stopped, and then the mixture is allowed to stand in the agitation tank for a certain period of time. For example, it can be allowed to stand for 1 to 3 days.

Mineral particles with a high specific gravity are precipitated at the bottom of the stirring tank through settling for a certain period of time and separated from the liquid supernatant. Along with this, an aging process in which various mineral components are eluted and fused with each other during the settling time is stabilized.

4. Supernatant water recovery step

Next, the supernatant separated from the solids is recovered after the precipitation aging step.

The supernatant can be recovered by discharging the supernatant to the outside of the stirring tank using the supernatant discharge pipe.

5. Filtration step

Next, the supernatant is filtered through a filter.

In the solid-liquid separated supernatant, a small amount of mineral powder is mixed and remains. These mineral powders cause discoloration of the supernatant over time. Therefore, it is necessary to remove the mineral powder remaining in the supernatant.

If the structure can remove fine particles, various filters can be applied. For example, a reverse osmosis (RO) filter or a hollow fiber membrane (HF) filter may be used.

When the supernatant is filtered through a filter, a liquid deodorant is finally prepared.

The liquid-type deodorant prepared in this way is safe for the human body and the surrounding environment and has an excellent deodorizing effect. In addition, since the deodorant prepared according to the present invention is provided in a liquid form, it is convenient to use and store, and can be formulated into various formulations, so that it can be usefully used in a wide range of fields.

The deodorant prepared according to the present invention can be used for various purposes. For example, it can be used for deodorization to remove odors generated from water treatment facilities, food waste treatment facilities, and livestock facilities. In addition, it can be used not only for deodorization but also for antibacterial purposes.

Hereinafter, the deodorizing effect of the deodorizing agent was confirmed through an experiment.
