  EMBODIMENT OF THE INVENTION The form for implementing the manufacturing method of the petrochemical ashes ash which concerns on this invention is demonstrated below based on an Example.

  The method for producing petrified ashes ash according to the embodiment will be described with reference to FIGS. FIG. 1 shows a ball mill 1, a vibration sieve 3, and a vacuum melting furnace 2 that are necessary for carrying out the method for producing a petrochemical ashes ash according to the present invention. The ball mill 1 is used to pulverize the remains, the vibration sieve 3 is used to classify the crushed remains ash, and the vacuum melting furnace 2 is used to heat and melt the remains.

  In this embodiment, the ball mill 1 is used as a means for pulverizing the remains ash (ashes), but the present invention is not limited to this, and the means for pulverizing these may be other pulverization. You may use the machine. Moreover, the vibration sieve machine can use a general desktop type vibration sieve machine, and can also use a sonic sieve machine or the like.

  In addition, the vibration sieve machine 3 performs classification using a three-stage nylon mesh sieve, and in the first stage, the input ashes ash is diffused to the front of the sieve surface and efficiently screened. A very coarse mesh (30 mesh) sieve is arranged to remove impurities mixed in the ashes ash, and a 100 mesh sieve is arranged below (second stage) and further below (3). In the stage), a 150 mesh sieve is arranged so that the ashes ash that has passed through the 150 mesh can be taken out.

  As shown in FIG. 1, the vacuum melting furnace 2 includes a substantially cylindrical vacuum chamber 4 and a vacuum pump 5 connected to the vacuum chamber 4 for reducing the atmospheric pressure in the vacuum chamber 4 to bring it into a vacuum state. (See FIG. 2), an oscillating table 6 that supports the vacuum chamber 4 and the vacuum pump 5 and can apply vibration to the entire vacuum chamber 4 is provided. The vacuum chamber 4, the vacuum pump 5, and the vibrating table 6 are connected to the control unit 10 through electric cables 7, 8, and 9, and the operator can control the vacuum melting furnace 2 by operating the control unit 10. It is like that.

  As shown in FIG. 2, on the front surface of the vacuum chamber 4, an openable / closable lid 13 is provided in which a monitoring window 11 is formed for an operator to monitor the inside of the vacuum chamber 4. A connection part 14 is formed on the upper part of the vacuum chamber 4, and an adapter 15 provided with a monitoring window 12, a temperature sensor (not shown) and the like is connected to the connection part 14.

  The connecting pipe 16 connecting the vacuum chamber 4 and the vacuum pump 5 is provided with a leak valve 17, and the decompressed state in the vacuum chamber 4 can be released by opening the leak valve 17.

  As shown in FIGS. 3 and 4, the vacuum chamber 4 has a double wall dewar structure, and can insulate the inside and the outside of the vacuum chamber 4. Inside the vacuum chamber 4, there is provided a swinging table 19 that can swing in the vertical direction about a pivot 18 provided on the inner surface of the vacuum chamber 4. The swinging table 19 is located on the side of the vacuum chamber 4. It is swung by the drive of the drive motor 20 attached to the section.

  A crucible socket 22 for holding the heat-resistant crucible 21 is attached on the rocking table 19, and a high-frequency coil 23 is clamped around the crucible socket 22. The high frequency coil 23 is connected to a coaxial electrode 24 provided through the axis of the drive motor 20, and power is supplied to the coaxial electrode 24 from the control unit 10 via the electric cable 7. (See FIG. 1). In this embodiment, a heat-resistant crucible 21 such as a high-density carbon crucible is used.

  In the present embodiment, a heat-resistant crucible 21 is used. The heat-resistant crucible 21 has a bottomed cylindrical shape, and ashes ash powder 27 obtained by pulverizing the remains 26 by the ball mill 1 is placed therein. The carbon crucible 21 in which the ashes ash powder 27 is introduced and melts the ashes ash powder 27. When the carbon density is low, the thermal conductivity of the crucible 21 is relatively low, and temperature unevenness occurs due to heating. Since it becomes easy, it is preferable to use the heat-resistant crucible 21 with good thermal conductivity.

  If the heat-resistant crucibles 21 are thin, heat from a high-frequency heating coil (described later) is locally applied to the ashes ash powder 27 and excessive convection due to temperature unevenness in the ashes ash powder 27. While deformation due to occurrence and scattering due to the bumping phenomenon of the molten ashes ash 27 are likely to occur, if the thickness is thick, the cause is not clear, but the phenomenon that the molten ashes ash 27 partially scatters frequently occurs. It is preferable to use about 3 mm.

  As shown in FIG. 5, a heat-resistant heat insulating material 31 such as ceramic wool is interposed between the crucible socket 22 (also referred to as an outer cylinder crucible) and the crucible 21. This heat-resistant heat insulating material 31 has a temperature decreasing rate of the portion 27b of the molten ashes ash 27 in contact with the melting crucible 21 and a portion 27a exposed to the reduced pressure atmosphere of the molten ashes ash 27 in the slow cooling step described later. The temperature decrease rate is the same means for making the temperature decrease rate substantially the same.

  Next, the process for producing the petrified ashes ash 28 from the remains 26 using the ball mill 1, the vibration sieving machine 3, and the vacuum melting furnace 2 in the present embodiment described above will be described based on the flowchart shown in FIG. To do.

  Ashes 26 cremation in the crematorium include various metal components such as metal members used for sub-funerals and metal members used for dental treatment in the ashes ash. Remove the member.

  As shown in FIG. 11, first, a manually magnetized metal component such as an iron nail contained in the remains 26 cremated in the crematorium is attracted by a permanent magnet or the like (which may be an electromagnet) having magnetic force. Remove (S1, magnetic force removal step). Moreover, the metal component which is not adsorbed by the magnet is removed by visual observation (S2, visual removal step). It should be noted that external contaminants other than metal such as refractory material, earth, sand, stone, glass, lime, and brick waste should be removed as much as possible.

  When the metal component is included in the remains 26, the metal component is rapidly vaporized due to the influence of high frequency or high temperature due to the ambient temperature during heating and melting described later. Therefore, there is a bumping phenomenon in which the molten ashes ash 27 melts, and the molten ashes 27 melted by the bumping phenomenon may be scattered. There is a risk of shape defects. Therefore, metal components are removed as much as possible.

  The cremated remains 26 include various metal components such as aluminum, chromium, and cobalt. These metal components are those in which external contaminants such as clothing and accessories included in the sub-funeral are burned during the cremation and attached to the remains 26. For example, as shown in FIG. 6, the remains 26 are attached with a silver material such as an aluminum foil 32 or a brown material such as a copper melt 33. There is a blue weld 34 attached. These colored portions of the remains 26 are manually scraped off the remains 26.

  The visual removal step includes a selection step of selecting a portion of the remains 26 used for manufacturing the petrified ashes 28. The remains 26 contain various substance components in addition to the main component calcium phosphate. In particular, the metal components included in the remains 26 cause a bumping phenomenon. The color of the ash 28 is affected.

  Therefore, the remains 26 are appropriately selected into a high content portion with a high metal component content and a low content portion with a low metal component content, and a predetermined site is used. FIG. 7 shows a long bone 25 such as a human femur, and in such a bone 25, the highly contained portion is a portion such as a joint portion 25a or a bone marrow portion 25b. The joint part 25a is a part containing a large amount of metal components to ensure joint strength, and the bone marrow part 25b is a part containing a large amount of metal components such as iron for hematopoiesis. In addition, since the structure of the joint portion 25a and the bone marrow portion 25b is a porous portion having a large number of voids, a metal component gasified or powdered during cremation is easily attached to this portion. You might also say that. Further, the low content portion is a portion such as the diaphyseal portion 25c (particularly the surface thereof). It is considered that this small content portion is dense with the main component of the bone 26.

  In this embodiment, the long bone 25 is referred to as an example of the high content part and the low content part. However, even in the case of bones such as the skull, pelvis, spine, etc., the high content part and the metal having a high content of metal components. Since there are some small content parts with a small content of components, these are selected and used as appropriate. Furthermore, when a high content portion is used, the petrified ashes ash 28 after production becomes a colored system (black, brown, gray, green, blue, purple, etc.), and a small content When the part is used, the petrified ashes ash 28 after production has a white color.

  In the present embodiment, a small content portion is used for the purpose of producing the petrochemical ash 28 having a white hue and for reducing the bumping phenomenon during heating and melting. In addition, since the occurrence of bumping phenomenon can be suppressed even with a trace amount of metal components, if the other metal components such as collateral funerals are completely removed, a colored system petrification can be used by deliberately using the content of the remains 26. The ashes ash 28 may be manufactured.

  Next, the remains 26 are washed with water. The remains 26 are put into the monkey 35 (see FIG. 8A), and the remains 35 are submerged in a container 37 containing water 36 (hot water) to wash the remains 26 (see FIG. 8B). By this water washing, the metal component that has been gasified or powdered during cremation and adhered to the remains 26 can be washed away by water washing (S3, water washing removal step).

  In particular, it is possible to remove water-soluble metal components that tend to ionize. In addition, in order to promote ionization of a metal component, it is good to wash with high temperature hot water 36. Furthermore, hot steam may be sprayed on the remains 26 and washed. Also, shower water can be poured over the colander 35 into which the remains 26 have been placed and washed. After the washed remains 26 are sufficiently dried, the process proceeds to the next step.

  Next, only the remains 26 from which the metal component has been removed and selected are put into the ball mill 1 and pulverized until the remains 26 become powdery (S4, pulverization step). As the ball mill 1, a planetary ball mill that is excellent in grinding power of solid powder can be suitably used, and the processing time may be appropriately selected depending on the condition of ashes and the like. It was carried out until the crushed ashes ash became a powder that could pass through a nylon mesh sieve (# 150) as appropriate. The remains 26 may be powdered manually using a mortar or the like. It should be noted that by grinding the remains 26, each part of the remains 26 (such as a high content part and a low content part) is made uniform. Moreover, it becomes easy to remove the metal component contained in the bone marrow, blood, etc. contained in the remains 26 in the process mentioned later.

  Next, the ashes ash powder 27 pulverized and homogenized by the ball mill 1 is charged from the upper charging port of the vibration sieving machine 3 and classified (S5, classification step). Specifically, as described above, the ashes ash powder 27 that has passed through 150 mesh (about 120 microns) is discharged from below the vibrating screen machine 3.

  Next, a high content portion containing a large amount of metal component is adsorbed and selected by a magnet having a magnetic force and removed from the ashes ash powder 27 (S6, magnetic force selection step). In the visual removal process described above, a certain amount of highly contained parts are removed manually, but this magnetic force sorting process is performed to further remove the metal component. Since the ashes ash powder 27 is in the form of powder, the ashes ash powder 27 containing a small amount of metal components is adsorbed by the magnet, and the high content portion and the low content portion can be selected.

  Next, the metal component is removed from the ashes ash powder 27 using the complex reagent solution 38 (S7, reagent removal step). In this step, the ashes ash powder 27 is put into a beaker 39 containing a complex reagent solution 38 such as a chelate reagent having a complex forming ability (see FIG. 9A). In this embodiment, a complex reagent solution 38 such as ethylenediamine, bipyridine, ethylenediaminetetraacetic acid, phenanthroline, porphyrin, and crown ether can be used, but other complex reagent solutions 38 may be used.

  Then, the complex reagent solution 38 into which the ashes ash powder 27 is charged is sufficiently stirred using the stirring rod 40 (see FIG. 9B). By impregnating the ashes ash powder 27 into the complex reagent solution 38, the metal component is removed from the high content portion of the ashes ash powder 27, and the high content portion changes to the low content portion. The removed metal component dissolves in the complex reagent solution 38 and the color of the complex reagent solution 38 changes, so that the operator can easily determine that the metal component has been removed.

  Thereafter, the ashes ash powder 27 is separated from the complex reagent solution 38 using the funnel 41 (see FIG. 9C). After the ashes ash powder 27 accumulated in the filter 42 of the funnel 41 is sufficiently dried. Move on to the next step. Further, among the ashes ash powder 27 immersed in the complex reagent solution 38, the high content portion is colored by the complex reaction, so that the operator can visually identify the high content portion. Therefore, you may make it remove these colored many content parts by visual observation before moving to the next process.

  Next, the ashes ash powder 27 is put into the heat-resistant crucible 21 (see FIG. 10A), the lid 13 of the vacuum chamber 4 is opened, and the crucible 21 is attached to the crucible socket 22 in the vacuum chamber 4. Then, the lid 13 of the vacuum chamber 4 is closed and the vacuum pump 5 is operated, and the inside of the vacuum chamber 4 is depressurized to be in a vacuum state (depressurized atmosphere state) (S8, depressurization step).

  As for the degree of vacuum in the vacuum chamber 4, as in the present invention, when ashes ash is 100% and contains no melting point depressant or binder, As will be described later, an ultra-high temperature of 1500 degrees Celsius (1500 ° C.) or higher is required. At temperatures of 1500 ° C. or higher, if there is air, especially oxygen around the remains, the normal atmosphere including humidity The composition of the crushed ashes ash is easily changed to a substance that is easily decomposed, and if the obtained petrified ashes ash is left in a normal atmosphere, cracks, cracks, whitening, and even pulverization will occur. Therefore, since it does not become a good petrified ashes ash, these oxygen may be a relatively low pressure, specifically, a reduced pressure atmosphere of 100 Pascal (Pa) or less, in order to stably obtain a petrified ashes ash, Preferably 40 packs Cal (Pa) or less, and more preferably may be a reduced pressure atmosphere of 10 Pascal (Pa) or less.

  When the inside of the vacuum chamber 4 is in a vacuum state (depressurized state) of the predetermined pressure described above, a current is passed through the high-frequency coil 23 to start heating the ashes ash powder 27 in the heat-resistant crucible 21 (S9, high-frequency heating and melting step). . In the vacuum melting furnace 2 of the present embodiment, the temperature reaches about 1400 ° C. in about 15 to 20 minutes. Depending on the type of ashes ash, etc., generally, the softening of the powder starts around 1420 ° C., and melting of a part of the powder is recognized around 1480 ° C.

  After the temperature of 1480 ° C., the temperature of the molten ashes ash 27 in the heat-resistant crucible 21 is carefully watched, and the temperature is gradually increased so as not to cause bumping. The temperature is raised to a temperature in the range of 1550 to 1650 ° C. over about 3 to 5 minutes. At this time, the vibrating table 6 may be operated to apply vibration to the vacuum chamber 4 so that local melting occurs and bumping or the like does not occur.

  As a result of the heating, the molten ashes ash 27 that has started melting near 1480 ° C. may be uniformly melted at about 1550 ° C. if it is low, or may not be melted uniformly to near 1650 ° C. if it is high. However, most of them melt uniformly in the range of 1550 degrees to 1650 degrees Celsius, so the melting temperature of the molten ashes ash 27 may be in the range of 1550 degrees to 1650 degrees Celsius.

  Even in the range of 1550 degrees to 1650 degrees Celsius, as described above, the temperature at which the molten ashes ash 27 is uniformly melted varies depending on the type of the molten ashes ash 27. It is preferable to check and hold the heating at a temperature slightly higher than the temperature at which it is uniformly melted in these temperature ranges, and to suppress the melting temperature to a temperature within the range of 1550 to 1650 degrees Celsius and capable of being stoned as uniformly as possible. .

  Until the uniform melting, as shown in FIG. 10A, the heat-resistant crucible 21 is erected, and the molten ashes ash 27 is accumulated in the bottom 21 a of the heat-resistant crucible 21. The operator monitors the inside of the heat-resistant crucible 21 from the monitoring window 12 provided at the upper part of the vacuum chamber 4, and when the molten ashes ash 27 is sufficiently melted, the vibrating table 6 is operated to give vibration to the vacuum chamber 4. Thus, vibration is applied to the heat-resistant crucible 21 disposed inside the vacuum chamber 4 (S10, vibration step).

  Applying vibration to the heat-resistant crucible 21 in this manner, that is, applying vibration to the molten ashes 27 that have been uniformly melted makes it easier for the gas contained in the molten ashes 27 to be discharged to the outside, Due to the difference in specific gravity of the ashes ash 27, a substance having a high specific gravity concentrates downward, so that it is possible to reduce the occurrence of cracks and cracks due to uneven composition and the occurrence of shape defects. However, the vibration process may be omitted as appropriate.

  Next, after the vibration of the heat-resistant crucible 21 due to the operation of the vibrating table 6 is stopped, the heat-resistant crucible 21 is tilted by tilting the rocking table 19 as shown in FIGS. 5 and 10B. The molten ashes ash 27 is accumulated over the bottom 21a and the inner peripheral side wall 21b. In this state, the heating is stopped and the cooling is gradually performed (S11, gradual cooling step). The slow cooling may be performed by, for example, natural cooling. If the rate of temperature decrease is large, reheating may be performed as appropriate so that the solidified (petrotized) petrified ash 28 does not crack. good.

  Note that a heat-resistant heat insulating material 31 made of ceramic wool as a means for the same temperature decrease rate is provided between the crucible socket 22 (also referred to as an outer cylinder crucible) and the crucible 21 so that the heat-insulating material 31 can melt the crucible 21. It is difficult to conduct heat to the crucible socket 22 and the temperature lowering speed of the molten crucible 21 is reduced by the heat insulating material 31, so that the temperature lowering speed of the portion 27b of the molten ashes 27 that contacts the molten crucible 21 can be reduced. This temperature decrease rate is substantially the same as the temperature decrease rate of the portion 27a exposed to the reduced pressure atmosphere of the molten ashes 27. Moreover, the heat insulating material 31 is comprised with the material which can also be equal to the high temperature in the melting process called ceramic wool, and it becomes possible to use the heat insulating material 31 in both a melting process and a slow cooling process.

  Then, it is confirmed that the molten ashes ash 27 is solidified (petrified) into a petrified ashes ash 28 by slow cooling, and after the temperature has been sufficiently lowered, the leak valve 17 is opened to release the reduced pressure state, and then the vacuum chamber 4 lid 13 is opened and heat-resistant crucible 21 is taken out.

  It is only necessary to take out the petrified ashes ash 28, which is a solidified (lithiated) ashes ash powder, from the heat-resistant crucible 21 thus taken out, and the surface 29 of the petrified ashes ash 28 is a molten liquid surface and becomes a mirror surface. . If necessary, the surface 29 may be decorated with a character 30 or the like using a YAG laser or the like. Note that the petrified ashes ash 28 produced in this example is considered to have a component structure similar to fluorite.

  As described above, according to the method for producing petrochemical ashes ash according to the present embodiment, various metal components such as metal members used for sub-funerals and cremation tools, and metal members used for dental treatment, surgical treatment, etc. Although the metal components contained in the body 27 are removed in advance in the removal steps S1, S2, S3, S6, and S7, the metal components are included in the melting step S9. In the middle, for example, it is possible to remarkably reduce the occurrence of bumping phenomenon due to, for example, rapid vaporization by heating or reaction with components in the molten ashes 27. Can be manufactured. The metal component of the present embodiment includes not only metal members used during cremation but also internal metal components such as blood condensed in the bone marrow of the remains 26.

  In addition, by including magnetic force removal steps S1 and S6 for removing the metal component from the ashes ash powder 27 by magnetic force, the magnetizable metal component used in the sub-funerals and the like is adsorbed by a magnet having magnetic force, etc. It can be easily removed from the ash powder 27, and the occurrence of bumping phenomenon of the molten ashes ash powder 27 can be significantly reduced. In addition, the part containing many metal components in the body such as blood in the ashes ash powder 27 can be removed with a magnet or the like.

  Further, by including the water removal step S3 for washing the remains 26, the metal contained in the remains 26 can be removed by a magnet or the like by being gasified or powdered and attached to the remains 26 during cremation, for example. Even if it is difficult, it can be easily removed from the remains 26 by being dissolved (ionized) in water by washing with water, and the occurrence of bumping phenomenon of the molten ashes ash 27 by the metal adhering to these remains 26 can be significantly reduced. .

  Further, by including the reagent removal step S7 for removing the metal component from the ashes ash powder 27 using the complex reagent solution 38, the metal contained in the ashes ash powder 27 is good even by, for example, adsorption with a magnet or washing with water. Even if these metals cannot be removed easily, they can be easily removed from the ashes ash powder 27 by complexing them with the complex reagent solution 38. It can be significantly reduced.

  In addition, by including sorting and removing steps S2 and S6 for sorting and removing a high-contained portion containing a large amount of metal component in the remains 26, the bone 25 is partially filled with metal in addition to calcium phosphate as the main component. Since there are relatively many containing parts, the occurrence of bumping phenomenon of the molten ashes ash 27 by metal can be further reduced by selecting and removing these containing parts.

  Further, since the bone-containing part of the bone 25 is the joint part 25a or the bone marrow part 25b, the joint part 25a is a part containing a large amount of metal components for securing joint strength, and the bone marrow part 25b is hematopoietic. Therefore, the metal component can be removed from the ashes ash powder 27 by removing these many-containing portions. The sorting / removing step of sorting and removing the high content portion of the remains 26 is not limited to the visual removing step S2 in which the operator visually selects and removes the joint portion 25a or the bone marrow portion 25b, but also the magnetic force sorting step S6. And the like, a step of adsorbing and removing a high content portion from the powdered ashes ash powder 27 by a magnet or the like is also included.

  Although the embodiments of the present invention have been described with reference to the drawings, the specific configuration is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. It is.

  For example, in the above embodiment, the method for producing petrified ashes ash according to the present invention was used when calcining the remains of the deceased to produce the petrified ashes 28, but the present invention is not limited thereto. Alternatively, it may be used for producing the petrified ashes 28 by burning bone ash when pet animals such as dogs and cats are cremation.

  Moreover, in the said Example, when the ashes ash powder 27 in the vacuum chamber 4 is heated and melted, the high frequency coil 23 is used for high frequency heating, but it is used when the ashes ash powder 27 is heated and melted. The heating means is not limited to high-frequency heating, and the ashes ash powder 27 may be heated and melted by light heating using a laser beam, or the ashes ash powder 27 is heated and melted by electric heating using heat generated by electric resistance. May be.

  Further, it is not necessary to heat and melt the ashes ash powder 27 in the heating and melting process by high frequency heating. For example, the ashes ash powder 27 is heated to a predetermined temperature by using electric heating at the beginning of the heating and melting process. Then, the ashes ash powder 27 may be heated to a higher temperature by switching to heating by high-frequency heating. A plurality of heating means may be alternately switched during the heating and melting step, or may be used simultaneously.

  Moreover, in the said Example, although the petrified ashes ash 28 is made into the rice ball-shaped plate (figure) as shown in FIG. 12, this invention is not limited to this, The shape of these petrified ashes ashes 28 is shown. By introducing molten ashes ash 27 into carbon molds of various shapes, for example, it can be made into a ball shape, pendant, bracelet, ring, earring, earring, rosary, eggplant, mobile phone strap, key holder, Ornaments such as objects may be formed.

  In the above-described embodiment, the ashes ash powder 27 is introduced into the beaker 39 containing the complex reagent solution 38 in the reagent removing step. For example, the ashes 26 are added to the ball mill 1 used in the pulverizing step. The complex reagent solution 38 may also be poured into the ball mill 1 together with the complex reagent solution 38 while pulverizing the remains 26. In this case, the ashes ash powder 27 taken out from the ball mill 1 using the funnel 41 and the complex reagent solution 38 are separated and dried well.

  In the above embodiment, the reagent removing step is provided after the pulverizing step. However, before the ashes 26 are pulverized, the ashes 26 may be impregnated in the complex reagent solution 38, and the many-containing sites are formed by complex reaction. Since it is colored, the operator may visually identify the high-contained sites and take measures such as scraping these colored sites off the remains 26.

  Moreover, in the said Example, one site | part selected by classify | selecting the high content site | part with many metal component content and the low content site | part with little metal component content in the selection process S2, S6, S7. The ashes ash powder 27 of the low content part is melted in the melting step S9, but the high content part and the low content part are appropriately mixed so as to become the petrified ashes ash 28 of the color desired by the bereaved family. The prepared ashes ash powder 27 may be melted in the melting step S9.

  In addition, the ashes ash in the present invention may be one obtained by crushing only bones that have been cremated and boned (actually the ash content at the time of cremation is included on the surface), It may be a mixture of ash, including those with a remains of 100% (ash of 0%).

  In the above embodiment, in the pulverizing step S4, the remains 26 are pulverized until they are powdered. However, in order to melt and solidify, it is not always necessary to pulverize the remains 26, and a part of the remains 26 is obtained. May be fragments of a predetermined size.
