  By the way, in recent years, bamboo black charcoal and bamboo white charcoal are attracting attention among bamboo charcoal because of their unique high functionality, and their use is strongly desired. However, since fine temperature control in the charcoal kiln is almost impossible, temperature unevenness is unavoidable, and carbides are generated in a state where impurities such as dust float in the kiln, so the disclosure of the above document is disclosed.

It becomes possible for the first time to be used as a material for a purified molded body.

(Premise of invention)
As a premise for explaining the embodiment of the present invention, bamboo charcoal including bamboo black charcoal and bamboo white charcoal will be described.
Bamboo black charcoal and bamboo white charcoal are a kind of bamboo charcoal obtained by carbonizing bamboo (Moso bamboo, true bamboo, maitake, light bamboo, etc.) Bamboo can be collected at the same place every year due to its resuscitation function compared to other materials (wood, coconut, etc.) used as a raw material for carbides, so it is very resource-rich and changes the place of charcoal production. There is no need.

In addition, bamboo has a unique structure in which the vascular bundle is distributed densely on the epidermis side and coarsely on the inner side, so that the epidermis is harder than the epidermis such as wood and coconut husks, and silicate compounds (silicon dioxide, etc.) Contains a lot. Therefore, even if bamboo is carbonized, most of the fine pores and silicate compounds that exist in the epidermal cell tissue before carbonization remain without being lost. The following Table 1 shows the ash composition (part) of each of Munetake bamboo and true bamboo after carbonization. Table 1 also shows that a large amount of the silicate compound contained in the bamboo skin remains after carbonization.

  As described above, bamboo charcoal has a high adsorbing ability because a large number of fine pores remain, and thus exhibits a deodorizing action, a humidity control action, a sterilization action, a water purification action, a sick house prevention action, and the like. In particular, the sterilization effect that bamboo charcoal has cannot be exhibited by other charcoal (for example, charcoal, oak charcoal, coconut charcoal). In addition to these effects, bamboo charcoal also exhibits catalytic action and the action of generating negative ions and far-infrared rays. The effects of negative ions and far infrared rays will be described later.

  And according to the “vacuum carbonization carbonization method” described later, it is possible to obtain a highly functional bamboo charcoal that is extremely lightweight with a specific gravity of about 0.35 and that exhibits each of the above-described functions extremely remarkably.

To support some of these properties of bamboo charcoal, for example, a research report by Mr. Ikuo Abe of Osaka City Institute of Engineering is known. He performs the following measurements 1 and 2.
<Measurement 1>
The surface area of bamboo charcoal is measured by applying iodine solution to the surface of bamboo charcoal and adsorbing iodine atoms into the fine pores of bamboo charcoal. The same measurement was conducted for coconut shell charcoal and oak charcoal.
<Measurement 2>
Measures the radius of fine pores in bamboo charcoal according to the mercury intrusion method. The same measurement was conducted for coconut shell charcoal and oak charcoal.

Then, the <Measurement 1> is "charcoal, like PKS charcoal and oak charcoal has a very large specific surface area of 1g per 300 meters ^2." And the measurement results of the have been published.

Regarding <Measurement 2>, “the radius of the fine pores of bamboo charcoal was 27 nm at the maximum, whereas the fine pores with radius reaching 112 nm for coconut charcoal and 129 nm for oak charcoal” were observed. The measurement results are published. Note that “1 nm = 10 ⁻⁹ m”.

  In addition to these, “Bamboo charcoal has a high purification action, such as the disappearance of phosphates and silicates that cause red tide in a short period of time (for example, 3 days). The prospects are expected to be used in many ways. "

  Based on the above-described characteristics of bamboo charcoal, embodiments of the present invention will be described in detail below with reference to the accompanying drawings with examples of environmental purification molded bodies.

(Example of molded product)
Fig.1 (a) is a schematic external view of the environmental purification molded object which is an example of embodiment of this invention, (b) is a figure which shows this one example of use.
The environmental purification molded body (ion-reduced carbon ceramic ball) α shown in the figure is obtained by kneading and mixing bamboo black charcoal powder 1, bamboo white charcoal powder 2 and zeolite powder 3 with the composition weight ratio shown in Table 2 below. After forming into a shape (in the figure, round granular shape), it is configured by sintering. This environmental purification molded body α is provided for use by placing a container-shaped bag A containing a large number thereof in a desired place in a living / living space such as a residence or office. Note that a metal mesh case, a cloth bag, or the like may be used to store a large number of environmental purification molded bodies α to be used.

  The bamboo black charcoal powder 1 contained in the environmental purification molded body α is a powder of bamboo black charcoal obtained by carbonizing bamboo at about 700 ° C. (black carbonization). Bamboo black charcoal is a kind of bamboo charcoal and has excellent adsorbing ability, and thus exhibits any effects resulting from adsorbing ability such as deodorizing action, humidity control action, sterilization action, water purification action, and sick house prevention action. In addition to these functions, bamboo black charcoal has an effect of generating far infrared rays by heat sensitivity.

  On the other hand, the bamboo white charcoal powder 2 contained in the environmental purification molded body α is a bamboo white charcoal powder obtained by carbonizing (white carbonizing) bamboo at about 1,000 ° C. Bamboo white charcoal is a kind of bamboo charcoal similar to bamboo black charcoal, so that it has excellent adsorptivity and is harder than bamboo black charcoal and has low electrical resistance. In particular, bamboo white coal easily generates negative ions because of its low electrical resistance and good conductivity. When exposed to nitrogen gas, bamboo white coal having such characteristics is activated (activated) to become activated bamboo charcoal. Bamboo black charcoal also generates negative ions, but not as pronounced as bamboo white charcoal.

  Here, in addition to neutralizing positive ions, negative ions (1) protect humans and animals (hereinafter referred to as “humans”) from electromagnetic waves, and (2) act on human parasympathetic nerves. (3) has the effect (minus ion effect) of activating cells such as humans by sedation and strengthening their vitality. Therefore, it has been attracting attention in recent years.

  The zeolite powder 3 contained in the environmental purification molded body α is a calcined zeolite powder. Zeolite is another name for silicate-alumina hydrated mineral (Japanese name "Zeolite"), one of the naturally produced talc materials, and its surface has regularly arranged fine pores of uniform molecular level (about 1nm to 70nm). Yes. When the zeolite having such a structure is dehydrated by a calcination treatment at a specific temperature or lower, cavities (micropores) containing water molecules remain intact without being broken, and the characteristics of the zeolite described below are sufficiently extracted. It becomes.

  That is, the zeolite has a high adsorbing ability when it is calcined, and not only exhibits a deodorizing action, a humidity control action, a sterilization action, a water purification action, and a sick house prevention action, but also (1) Adsorb only molecules smaller than the pore size of the micropores, that is, molecular sieve action that sorts molecules smaller than the pore size of the micropores and larger molecules, and (2) materials with dipoles, quadrupoles, unsaturated bonds, and polarizability It also exhibits extremely high polarity and the like, which adsorbs a high substance more strongly than in a general polar adsorbent (for example, silica gel, activated alumina).

  In addition, zeolite has a cation exchange ability for reducing positive ions adsorbed in the micropores to negative ions and desorbing them, that is, exchanging positive ions for negative ions, due to its catalytic action. Since these properties of zeolite are never found in other general minerals, zeolites having such properties may be used for high-performance ecological building materials and the like.

(Example of manufacturing method)
Next, an example of a manufacturing process of the environmental purification molded body α will be described with reference to FIGS. 2 to 6.
Here, FIG. 2 is a process diagram showing an example of a processing procedure of the manufacturing process of the environmental purification molded body α, FIG. 3 is a process diagram showing an example of a processing procedure of a previous process constituting the manufacturing process, and FIG. FIG. 5 is a process diagram showing an example of a processing procedure example of a bamboo white charcoal generation process constituting the manufacturing process.
6 (a) is a schematic configuration diagram of a bamboo carbonization furnace used in the bamboo black coal production process and the bamboo white coal production process, FIG. 6 (b) is an enlarged view of the vicinity of the clutch furnace lid of the bamboo carbonization furnace, (c). Fig. 4 is a simplified sectional view taken along line II of the bamboo carbonization furnace, and (d) is a partially enlarged view of the injection thin tube of the bamboo carbonization furnace.

  In the present embodiment, as shown in FIG. 2, the manufacturing process of the environmental purification molded body α includes the previous process (ST1), the bamboo black charcoal production process (ST2a), the bamboo white charcoal production process (ST2b), and the bamboo charcoal fine powdering process. (ST3), zeolite powder mixing step (ST4), hydration step (ST5), kneading step (ST6), hydration step (ST7), molding step (ST8), and sintering step (ST9) are divided into 10 steps. These steps are performed in this order. In addition, a high-purity and high-quality bamboo black charcoal or bamboo white charcoal is made homogeneous by sequentially performing a pre-process (ST1) and a bamboo black charcoal production process (ST2a) or a bamboo white charcoal production process (ST2b) which are the following processing procedures. The method of mass production is the aforementioned “vacuum carbonization carbonization method”.

The pre-process (ST1) constituting the manufacturing process of the environmental purification molded body α is performed mainly for the purpose of processing the bamboo material that is black carbonized or white carbonized. This pre-process is performed according to the processing procedure shown in FIG.
That is, first, the harvested bamboo is cut and divided into an appropriate length (for example, about 1 m) (ST11). The best time to cut bamboo is from October to December, when bamboo stores a large amount of sugar.

  Next, the bamboo material obtained in ST11 is further divided into 4 to 6 pieces to obtain plate-like split bamboo (ST12). In addition, if it is a bamboo material once dried, it can be easily made into split bamboo. The split bamboo obtained in ST12 is bonded to some other split bamboo after removing the nodes and the like (ST13).

  Immediately thereafter, a plurality of split bamboos bound together are put into a potassium permanganate dilute solution having a concentration of 0.05% to 0.07% and soaked for a certain period (for example, 24 hours) (ST14). If this soaking is carried out, the sterilization and disinfection action of the dilute potassium permanganate solution can prevent the worm-eaten of the split bamboo, and the astringent action of this solution can provide the advantage that the number of micropores in the split bamboo is increased.

  In ST14, such a merit can be obtained by using a nitric acid solution in which nickel is dissolved instead of the potassium permanganate dilute solution. However, in this case, after being soaked with the nitric acid solution, it is necessary to wash the bound split bamboo taken out from this solution with water for acid removal.

  In any case, the bundled split bamboo that has been soaked in can be preserved for a long period of time because it is worm-eaten-prevented, so it is harvested by harvesting from October to December when a large amount of sugar is stored. Because the time is limited, high-quality bamboo material (bundled split bamboo), which is a processed material of bamboo that has been harvested in large quantities, can be gradually stocked according to demand without urgent carbonization, so it can be stocked in large quantities .

  Then, by removing the fully-bundled split bamboo from the potassium permanganate dilute solution and drying it sufficiently (ST15), a processed bamboo material suitable for black carbonization or white carbonization can be obtained. Become.

  As shown in FIG. 2, next to the previous step (ST1), there are a bamboo black coal production step (ST2a) for the purpose of bamboo black coal production and a bamboo white coal production step (ST2b) for the purpose of bamboo white coal production. Performed in parallel or back and forth. These bamboo black charcoal production process and bamboo white charcoal production process are performed using the bamboo carbonization furnace shown in FIG. 6 by the respective processing procedures shown in FIG. 4 or FIG.

Here, before explaining the detailed processing procedure of each of the bamboo black charcoal generating step (ST2a) and the bamboo white charcoal generating step (ST2b) shown in FIG. 2, these two steps are performed with reference to FIG. The bamboo carbonization furnace used suitably is demonstrated.
A bamboo carbonization furnace (hereinafter, also simply referred to as “carbonization furnace”) C shown in the figure includes a drawing work vehicle 4 with wheels 4 a that can be carried into and out of the inside. This drawer work vehicle 4 is normally placed and fixed on a carriage D placed outside the furnace C before the start of production of bamboo black charcoal or bamboo white charcoal in the carbonization furnace C, and at least bamboo black charcoal or bamboo white charcoal is produced. Immediately before the start, bamboo material B (processed in accordance with the preceding process shown in detail in FIG. 3 has been processed. The same applies hereinafter) is loaded and fixed at a predetermined position (shown by a two-dot chain line) in the carbonization furnace C. The Note that the example of loading bamboo material B onto the drawing work vehicle 4 shown in FIG. 6 is a simple example of illustration, and a plurality of bamboo materials B are provided so as not to interfere with the loading / unloading of the drawing work vehicle 4 into the carbonization furnace C. Needless to say, the vehicle is loaded on the extraction work vehicle 4.

  In order to raise the heat insulating property in the carbonization furnace C, the stainless steel layer 5a, the fine ceramics layer 5b as a heat insulating layer, and the stainless steel layer or the steel layer 5c are laminated on the furnace wall 5 in this order from the inside except the inner bottom portion. A three-layer structure is adopted. Note that the structure adopted for the furnace wall 5 in order to increase the heat insulating property in the carbonization furnace C is not limited to such a three-layer structure, and includes a plurality of heat insulating layers including at least one heat insulating material such as fine ceramics. What is necessary is just a multilayer structure in which layers are stacked.

  The furnace wall 5 of the carbonization furnace C is provided with an exhaust pipe 6 for evacuating the furnace C. The outer end of the exhaust pipe 6 (exposed from the furnace C to the right in the drawing) is carbonized. While connected to a vacuum pump E placed outside the furnace C, foreign matter having a predetermined particle size or more (for example, these fine powders remaining after the formation of bamboo black charcoal or bamboo white charcoal) is vacuum pumped at the inner end. A filter member 24 for preventing suction by E is attached. The vacuum pump E is controlled based on the detected values of two vacuum gauges 7 and 8 (one or more is sufficient) installed in the carbonization furnace C as a vacuum degree detection means, so that the inside of the furnace C Is reduced and maintained at the vacuum level of the target pressure value.

  The carbonization furnace C includes a clutch furnace lid 9 that can be opened and closed in the vertical direction of the drawing. The clutch furnace lid 9 is opened and closed by a furnace lid opening / closing support mechanism 10 so that the clutch furnace lid 9 can be opened and closed. However, it is controlled manually. Only when the clutch furnace lid 9 is opened can the drawer work vehicle 4 be carried into and out of the carbonization furnace C. In the present embodiment, in order to further improve the airtightness and sealing performance in the carbonization furnace C in which the clutch furnace lid 9 is closed, and to prevent the closed clutch furnace lid 9 from being flooded, By transmitting the driving force of the hydraulic motor 11 installed outside 5 to the hydraulic rotary clutch ring 13 via the hydraulic cylinder 12, the hydraulic rotary clutch ring 13 is rotated by a predetermined angle in a predetermined direction to open the furnace wall 5 A mechanism that tightly closes the end is adopted.

  In the carbonization furnace C, there is a tube-shaped stainless steel pipe 14 (which is also referred to as “SUS pipe” hereinafter) because the material is made of stainless steel. It is installed along the inner surface of the furnace wall 5 so as to be parallel to the left and right direction on the paper surface, and both ends thereof are outer end portions 14a and 14b exposed from the carbonization furnace C in the right direction on the paper surface. The outer end 14a of the SUS pipe 14 is connected to the oil burner 15, while the outer end 14b is connected to a chimney 16 (shown by a two-dot chain line) extending in the upward direction on the paper surface. The oil burner 15 is controlled based on a detection value of a temperature sensor 17 (for example, composed of a thermocouple) installed on the furnace wall 5 of the carbonization furnace C (which may be inside the furnace C) as temperature detection means. The carbonization furnace C is heated and maintained at the target temperature value.

  Furthermore, the carbonization furnace C has a nitrogen gas introduction pipe 18 to which cooled nitrogen gas is supplied from a nitrogen cylinder (not shown) installed outside thereof, and air that can take in air from outside air around the furnace C. And an introduction pipe 19.

  The nitrogen gas introduction pipe 18 is an arc or horseshoe-shaped pipe along the inner surface of the furnace wall 5, the top portion of which communicates with the outer opening end 18 a exposed from the carbonization furnace C and the lower ends on both sides become the closed ends 18 b. A nitrogen gas introduction / stop switching valve 20 is attached to the outer end 18 a of the nitrogen gas introduction pipe 18. The air introduction pipe 19 is also an arc or horseshoe-shaped pipe along the inner surface of the furnace wall 5, the top portion of which communicates with the outer opening end 19 a exposed from the carbonization furnace C and the lower ends on both sides become the closed ends 19 b. A valve 21 for air introduction / stop switching is attached to the outer end 19 a of the air introduction pipe 19.

  The pipes 18 and 19 are connected by a plurality of injection thin tubes 22, and the pipes 18 and 19 communicate with each other. The injection thin tubes 22 have injection holes 22 a for injecting nitrogen gas and air. 22b, 22c,... Are equally spaced with respect to the longitudinal direction. In short, in this embodiment, the nitrogen gas injection means includes the nitrogen gas introduction pipe 18, the valve 20, and the injection thin tube 22, and the air injection means includes the air introduction pipe 19, the valve 21, and the injection. It is composed of a thin tube 22 and is inexpensive. In addition, in each of the case of nitrogen gas injection and the case of air injection, the nitrogen gas introduction pipe 18, the air introduction pipe 19, and the injection thin tube 22 are selectively used without being inexpensive as in the present embodiment. And the injection thin tubes 22 may be arranged and combined.

Next, with reference to FIG. 4 or FIG. 5, the detailed processing procedure of each of the bamboo black charcoal generation step (ST2a) and the bamboo white charcoal generation step (ST2b) illustrated in FIG. 2 will be described.
As shown in FIGS. 4 and 5, first, the sufficiently dried bamboo material B is packed into the carbonization furnace C (ST21). This clogging is performed in detail by the following work procedure. (1) Bamboo material B is loaded on the drawer work vehicle 4 placed and fixed on the carriage D outside the carbonization furnace C. (2) Since the wheel 4a of the drawing work vehicle 4 is at the same level as the drawing work vehicle storage floor 23 of the carbonization furnace C, the drawing work vehicle 4 is moved from the stop position on the carriage D to the inside of the carbonization furnace C. Move and fix to a predetermined position (two-dot chain line shown).

  Next, the inside of the carbonizing furnace C is evacuated by the vacuum pump E (ST22). This evacuation is performed in detail by the following work procedure. That is, (1) The valve 20 with the nitrogen gas introduction pipe 18 and the valve 21 with the air introduction pipe 19 are tightened by hand, or it is confirmed that the valves 20 and 21 are tight. (2) The clutch furnace lid 9 supported by the furnace lid opening / closing support mechanism 10 so as to be opened and closed is manually closed. (3) In order to prepare for evacuation in the carbonizing furnace C, the driving force of the hydraulic motor 11 is transmitted to the hydraulic rotary clutch ring 13 via the hydraulic cylinder 12 so that the hydraulic rotary clutch ring 13 is predetermined in a predetermined direction. The angle is rotated to close and close the open end of the furnace wall 5. By doing so, a slight gap or the like existing between the furnace wall 5 and the hydraulic rotary clutch ring 13 is eliminated, so that the airtightness / sealing performance in the carbonization furnace C is further enhanced and it does not open to the flood. To do. (4) The vacuum pump E is operated to depressurize the carbonization furnace C until the detected values of the vacuum gauges 7 and 8 are reduced to the target pressure value.

  By this evacuation (ST22), most of impurities such as dust are removed from the inside of the carbonizing furnace C, so that it becomes possible for the first time to produce high-purity bamboo black charcoal or bamboo white charcoal with a very low impurity content.

  Next, in the case of the bamboo black charcoal production process, as shown in FIG. 4, the oil burner is used until the detected value of the temperature sensor 17 reaches a temperature value of about 700 ° C. just before the maximum heating limit value of the carbonization furnace C is about 800 ° C. 15 is operated to heat the inside of the carbonization furnace C (ST23). During this time, the hot air blown into the SUS pipe 14 from the oil burner 15 through the outer end 14a radiates heat to the surroundings while flowing in the pipe 14 toward the outer end 14b, whereby the bamboo material B is black carbonized. The temperature inside the carbonization furnace C is uniformly raised to a temperature value of about 700 ° C., and the heat necessary for the production of bamboo black coal is sufficiently distributed to every corner of the furnace C without causing temperature unevenness. As a result, the bamboo material B is black carbonized sufficiently and reliably up to the fiber material.

  Next, when all of the bamboo material B packed in the carbonization furnace C is completely black carbonized, the heating of ST23 is finished at that time, and the valve 20 is loosened at an appropriate time thereafter, and the nitrogen gas is introduced into the nitrogen gas introduction pipe 18. To cool the inside of the carbonization furnace C by uniformly injecting nitrogen gas from the injection ports 22a, 22b, 22c,... ST25). By doing in this way, the time required for lowering the temperature of bamboo black charcoal shortly after generation to room temperature will be much shorter than when using a charcoal kiln. The same applies to the case of the bamboo white charcoal generation step described below.

  On the other hand, in the case of the bamboo white charcoal production process, the oil burner 15 is operated until the detected value of the temperature sensor 17 reaches the maximum heating limit value of about 800 ° C., as shown in FIG. The inside is heated (ST23 ').

  Here, since the heating temperature value necessary for white carbonization of the bamboo material B is about 1,000 ° C., bamboo white charcoal cannot be obtained only by heating of ST23 ′. Therefore, when all of the bamboo material B packed in the carbonization furnace C is completely black carbonized, the valve 21 is temporarily loosened and air is temporarily introduced into the air introduction pipe 19 at each point, whereby each injection tubule The air is uniformly injected from the 22 injection ports 22a, 22b, 22c,... To heat the inside of the carbonizing furnace C (ST23 ″). By doing so, black carbonization is performed in the carbonizing furnace C. When the bamboo material B is exposed to air and ignites, the temperature in the carbonization furnace C is uniformly raised to a temperature value of about 1,000 ° C. at which the bamboo material B is white carbonized, and the furnace does not cause temperature unevenness. Since the heat necessary for producing bamboo white charcoal is evenly distributed to every corner in C (ST24), all these black carbonized bamboo materials B are white carbonized sufficiently and reliably up to the fiber material. This completes the heating of ST23 '.

  Further, when the inside of the carbonizing furnace C is sufficiently leveled and all the bamboo material B packed therein is completely white carbonized, after the valve 21 is closed and the introduction of air into the air introduction pipe 19 is stopped, an appropriate time point is reached. Then, the valve 20 is loosened and nitrogen gas is introduced into the nitrogen gas introduction pipe 18, whereby nitrogen gas is evenly injected from the injection ports 22a, 22b, 22c,. Is cooled (ST25). At this time, bamboo white charcoal already generated in the carbonization furnace C is activated (activated) by being exposed to nitrogen gas, and becomes activated bamboo charcoal.

  As described above, in the case of the bamboo black charcoal generating step, the processing procedures illustrated in FIG. 4 are sequentially performed, whereas in the case of the bamboo white charcoal generating step, the processing procedures illustrated in FIG. 5 are sequentially performed. If this is the case, it becomes possible for the first time to produce high-quality bamboo black charcoal and bamboo white charcoal that have been carbonized or white carbonized sufficiently and reliably up to the fiber using only a single device (carbonization furnace C).

  And in any case of a bamboo black charcoal production | generation process and a bamboo white charcoal production | generation process, if the inside of the carbonization furnace C is fully cooled, several produced | generated bamboo black charcoal or bamboo white charcoal will be taken out from the same furnace C together with the drawing work vehicle 4. . Thus, when the bamboo black charcoal generation process or the bamboo white charcoal generation process is completed, product inspection, safe storage, or the like may be performed. On the other hand, when shifting to a new bamboo black charcoal production process or bamboo white charcoal production process, each processing procedure illustrated in FIG. 4 or 5 is sequentially performed again. By doing in this way, it becomes possible for the first time to mass-produce high quality bamboo black charcoal and bamboo white charcoal that have been sufficiently and surely black carbonized or white carbonized up to fiber quality.

  In addition, the carbonization furnace C having the above-described configuration is different from existing charcoal baking kilns, and most of the smoke filled inside is used for black carbonization and white carbonization of bamboo without leaking to the outside. Although not suitable for liquid collection, it is not necessary to consider measures to prevent air pollution.

  As shown in FIG. 2, after the bamboo black charcoal production step (ST2a) and the bamboo white charcoal production step (ST2b), bamboo charcoal pulverization for the purpose of pulverizing the produced bamboo black charcoal and bamboo white charcoal. Step (ST3) is performed. Not only bamboo black charcoal powder and bamboo white charcoal powder obtained by this bamboo charcoal fine powdering process, but also residual bamboo black charcoal generated in carbonization furnace C in bamboo black charcoal production process (ST2a) or bamboo white charcoal production process (ST2b) If powder and bamboo white charcoal powder are also used, it is economical.

  Next to the bamboo charcoal fine powdering step (ST3), there is a zeolite powder mixing step (ST4) for the purpose of further mixing the zeolite powder into the mixture of bamboo black charcoal powder and bamboo white charcoal powder obtained in this step. Is called. Here, the ratio of bamboo black charcoal powder, bamboo white charcoal powder, and zeolite powder is set to the mixing weight ratio, 30% to 25%, 30% to 25%, and 40% to 50%, respectively.

  Simultaneously with or after the zeolite powder mixing step (ST4), a kneading step (ST6) is performed for the purpose of uniform kneading of each powder of bamboo black and bamboo white and zeolite powder while adding water as appropriate (ST5). . In this kneading step, for example, an existing mixer kneader or the like is used.

  Next to the kneading step (ST6), water is appropriately added to the kneaded product obtained in this step, so that the binder action of the zeolite powder contained in the kneaded product appears and the moldability is improved as necessary. The water addition process (ST7) aiming at this is performed.

  Next to the hydration step (ST7), the kneaded material obtained in this step, the binder action by the zeolite powder and the moldability action as necessary, which has already been revealed, is put into a mold, and an existing granulator is used. Thus, a molding step (ST8) for the purpose of extruding into a round particle of φ3 mm is performed. Even the granulated product obtained at this stage synergistically exhibits an effect effective for improving the environment and can be sustained semipermanently, but since the hardness is low, it does not maintain a certain shape and does not last long. In addition, the shape of the granulated product obtained in ST8 can be changed to a shape other than a round shape (for example, a quadrangular shape, a meteorite shape, or another globular shape) by using an appropriate stamping die.

  Next to the forming step (ST8), a sintering step (ST9) for the purpose of converting the molded product obtained in this step into a ceramic is performed using an existing dry distillation furnace, etc. Thus, a ceramic (environmental purification molded body α) having a hardness capable of maintaining the shape is obtained for the first time.

  Although the embodiments of the present invention have been described above, the present invention is not necessarily limited only to the above-described means, methods, and usage examples, and can be appropriately changed within the scope of achieving the above-described effects. It is possible to implement. For example, if figurines such as dolls, Buddha statues, dishes, vases, etc. are produced using the required amount of kneaded material consisting of bamboo black charcoal powder 1, bamboo white charcoal powder 2 and zeolite powder 3, it can be used as an interior that adds flowers to living and living spaces. Is also available.

  Also, if the required number of environmental purification molded bodies α are submerged in water (for example, aquariums, seas, rivers, lakes, and ponds), the water purification, eutrophication suppression, and sterilization can be achieved through the above-mentioned various functions. It is possible to contribute greatly to Furthermore, when aiming at soil improvement, the environmental purification molded body α may be buried in the soil.

  In addition, since the bamboo black charcoal powder 1 contained in the environmental purification molded body α has a feature of generating far infrared rays when heat-sensitive, various effects of the far infrared rays are expected by wearing the environmental purification molded body α. The That is, for example, if the environmental purification molded body α is put in the back pocket of the clothes or attached to the skin with a compress or the like, the environmental purification molded body α heats the body temperature and generates far infrared rays. The far-infrared rays emitted from the environmental purification molded body α are expected to have a heat retaining effect, an effect similar to a warm compress, and the like.
