[0015] Fig. 1 is a vertical cross-sectional view of the cremation equipment to which the present invention is applied, Fig. 2 is a vertical cross-sectional view showing the state in which the incineration table is lowered by the lifting mechanism, and Fig. 3 is a plan view showing the configuration of the reburning chamber. The cremation equipment shown in the figure is equipped with a main combustion chamber (cremation chamber) 2 for cremating the cremated body 1, which is the remains of a human or animal, a crematorium 4 including a reburning chamber (combustion chamber) 3 that reburns the gas generated in the main combustion chamber 2 to make it harmless, multiple cremation tables 6 on which the cremated body 1 is placed, a single entrance 7 for taking the cremated body 1 in and out of the main combustion chamber 2, and a lifting mechanism 8 that supports the incineration table 6 so that it can be raised and lowered.

[0016] The crematorium 4 is a space formed into a vertically long rectangular parallelepiped shape by a ceiling 9, a peripheral wall 11, and a floor 12, and the ceiling 9, the peripheral wall 11, and the floor 12 are made of insulating materials such as bricks or ceramics. In the crematorium 4, multiple main combustion chambers 2, 2 (two in this example) are arranged side by side in the vertical direction, and the reburning chamber 3 is arranged directly above the upper main combustion chamber 2. In addition, the two main combustion chambers 2, 2 and the reburning chamber 3 are connected by a flue 13 provided in the crematorium 4.

[0017] Furthermore, the crematorium 4 has a lower structural part 14 extending between the two main combustion chambers 2, 2, and an upper structural part 16 extending between the upper main combustion chamber 2 and the reburning chamber 3. These structural parts 14, 16 divide the space inside the crematorium 4 into three levels in a side cross-sectional view, and the thus divided spaces are configured as the reburning chamber 3, the first main combustion chamber 2, and the second main combustion chamber 2 from the top.

[0018] In addition, in both structural parts 14, 16, a square opening 18 is formed in a plan view so that a lift 17 of the lifting mechanism 8 described later can pass through. In other words, the crematorium 4 has an open atrium where each floor from the second main combustion chamber 2 to the reburning chamber 3 is connected by the opening 18.

[0019] The first main combustion chamber 2 is a rectangular parallelepiped space whose longitudinal direction is from the front to the back, and the aforementioned entrance 7 is formed in the peripheral wall 11 on the front side, while the heating device 19 for cremation is disposed in the upper part of the central side of the peripheral wall 11 on the back side. In addition, the first incinerator 6 is disposed along the longitudinal direction.

[0020] The second main combustion chamber 2 is a rectangular parallelepiped space whose longitudinal direction is from the front to the back, and a heating device 19 for cremation is disposed in the upper part of the central side of the peripheral wall 11 on the back side. Also, the second incineration table 2 is disposed along the longitudinal direction. That is, the incineration tables 6, 6 are provided in multiple levels, one above the other.

[0021] Each heating device 19, 19 is a burner 19, 19 that incinerates the cremated body 1 by spraying a flame toward the cremated body 1 or a wooden coffin 21 in which the cremated body 1 is placed, and its base end is embedded in an arrangement hole 22, 22 formed in the peripheral wall 11 of the crematorium 4 and is supported by a swinging mechanism (not shown) so that it can swing up and down and left and right. By this swinging action, the burner 19, 19 is configured to be able to adjust the direction of the flame spray.

[0022] The entrance 7 is opened and closed by a fire door 23 arranged in front of it and configured to be openable (raised and lowered) by an operating mechanism (not shown). In addition, the cremated body 1 or the coffin 21 containing the cremated body 1 is taken in and out of the first main combustion chamber 2 through this entrance 7.

[0023] The first incineration table 6 has a main body 24 formed in a rectangular parallelepiped shape elongated in the longitudinal direction of the first main combustion chamber 2 and having a placement surface for placing the cremated body 1 or the coffin 21 on its upper surface, a plurality of running wheels 26, 26 formed symmetrically on the lower side of the main body 24, and a support part 27 provided for each running wheel 26 and rotatably supporting the running wheel 26. The first incineration table 6 is configured as a movable table 6 that can be moved by the running wheels 26 in the horizontal direction or in a direction along the horizontal direction.

[0024] The second incineration stand 6 has a main body 28 formed in a rectangular parallelepiped shape elongated in the longitudinal direction of the second main combustion chamber 2 and having a placement surface for placing the cremated body 1 or the coffin 21 on its upper surface, a plurality of running wheels 29, 29 formed symmetrically on the lower side of the main body 28, and a support part 31 provided for each running wheel 29 and rotatably supporting the running wheel 29. The second incineration stand 6 is configured as a movable stand 6 that can be moved horizontally or in a direction along the horizontal direction by the running wheels 29.

[0025] Furthermore, both incinerator tables 6,6 may be configured so that the cremated body 1 or the coffin 21 can be placed on their placement surfaces. For example, they may not have running wheels 26,29 and support parts 27,31, and may be fixed tables 6,6 fixed to each main combustion chamber 2,2.

[0026] Next, the configuration of the lifting mechanism will be described with reference to FIGS.

[0027] The lifting mechanism 8 has a plurality of lifts 17 (two in this example) arranged in a vertical direction, a pair of left and right lifting rails 32, 32 that support the lifts 17, 17 so that they can be raised and lowered, and a lifting actuator. The first incineration table 6 is placed on the upper surface side of the lift 17 arranged above, while the second incineration table 6 is placed on the upper surface side of the lift 17 arranged below.

[0028] The pair of lifting rails 32, 32 are track members made of a material with excellent heat resistance such as ceramics, and are vertically extended from the floor 12 of the crematorium (second main combustion chamber) 4 to the lower end of the upper structure 16, and are arranged so that the distance between them is the same or approximately the same as the width (left-right length) of the lifts 17, 17 in a plan view. In addition, the lifting rails 32 are formed in a U-shape with the sides approaching each other open in a plan view.

[0029] The lift 17 is a thick plate member formed in a rectangular shape and made of a material having excellent heat resistance such as ceramic, and has engagement parts 33, 33 protruding symmetrically toward the left and right outside in a plan view. The engagement parts 33, 33 engage with a pair of U-shaped lift rails 32, 32, so that the lift 17 can be raised and lowered along the lift rails 32.

[0030] The lifting actuator is an electric actuator that is operated by power supplied from the outside, and lifts and lowers the lifts 17, 17 based on a signal output from a control unit 34 described later.

[0031] By raising the lifts 17, 17 arranged above and below by the lifting mechanism 8, the lower lift 17 is displaced to just above the lower structure 14 and raised to a height where the second incineration table 6 is located in front of the entrance 7, and the upper lift 17 is displaced to just below the upper structure 16 and raised so that the first incineration table 6 is located in the reburning chamber 3. On the other hand, by lowering the lifts 17, 17 arranged above and below, the lower lift 17 is displaced to just above the floor 12 of the crematorium 4 and the second incineration table 6 is located in the second main combustion chamber 2, and the upper lift 17 is displaced to just above the lower structure 14 and lowered to a height where the first incineration table 6 is located in front of the entrance 7.

[0032] As described above, by adopting a structure that allows the incineration table 6 to be positioned at the height of the entrance / exit 7 to be switched, different cremated bodies 1 or coffins 21 can be placed on each incineration table 6, 6 through a single entrance / exit 7.

[0033] The lift 17 may also have a pair of left and right guide rails 36, 36 laid in the front-rear direction on its upper surface. The guide rails 36 are formed in a concave shape when viewed from the front, and engage and support the running wheels 26, 29 so that they can rotate back and forth, thereby supporting the movable base 6 so that it can slide back and forth in the front-rear direction. This allows the movable base 6 to be easily inserted and removed from the main combustion chamber 2 through the entrance 7.

[0034] Next, the configuration of the reburning chamber 3 and the smoke treatment will be described based on Figures 1 to 4. Figure 4 is a block diagram showing the configuration of the smoke treatment. The reburning chamber 3 is provided with the outlet of the above-mentioned flue 13, and the exhaust gas containing harmful substances generated in each main combustion chamber 2, 2 during the incineration treatment of the cremated body 1 flows into the reburning chamber 3 through the flue 13.

[0035] The re-burning chamber 3 is a rectangular parallelepiped space whose longitudinal direction runs from the front to the back, and has a heating device 37 for re-burning, an opening and closing floor 38 that can be opened and closed, and a smoke exhaust duct 39 that leads the exhaust gas that has been re-burned to the exhaust gas treatment chamber 42.

[0036] The heating device 37 for re-burning is a burner 37 that performs re-burning by injecting a flame into the exhaust gas flowing into the re-burning chamber 3, and its base end side is embedded in an arrangement hole 41 formed in the peripheral wall 11 of the crematorium 4 and is supported so as to be able to swing up and down and left and right by a swinging mechanism (not shown). By this swinging action, the burner 37 is configured to be able to adjust the direction of the flame injection.

[0037] The opening and closing floor 38 is formed to be slightly smaller in thickness than the upper structure 16, is embedded in the upper structure 16, and is configured to be slidable in the left and right directions by an opening and closing mechanism (not shown). When the opening and closing floor 38 is in the open state, the opening 18 of the upper structure 16 is opened, and the first incinerator 6, which is lifted by the lift 17, is allowed to enter the reburning chamber 3, while when the opening and closing floor 38 is switched to the closed state, the opening 18 of the upper structure 16 is closed.

[0038] The smoke exhaust duct 39 has an entrance disposed at the front end of the ceiling 9 of the reburning chamber 3, and extends to a separately provided exhaust gas treatment chamber 42. The smoke exhaust duct 39 connects the reburning chamber 3 and the exhaust gas treatment chamber 42.

[0039] With the above-mentioned configuration, by switching the opening / closing floor 38 to the closed state and blocking the opening 18 during the incineration process of the cremated body 1, it is possible to prevent exhaust gas from leaking into the main combustion chamber 2 through the opening 18 due to convection associated with the re-burning process, and the exhaust gas that has been rendered harmless by the re-burning process can be introduced into the exhaust gas treatment chamber 42 through the exhaust smoke duct 39.

[0040] The exhaust gas introduced into the exhaust gas treatment chamber 42 is cooled and dust-collected by the cooling device and dust collection device installed in the exhaust gas treatment chamber 42, and is exhausted to the outside of the cremation equipment through the exhaust port.

[0041] Next, the configuration of the control unit 34 will be described with reference to Fig. 5. Fig. 5 is a block diagram showing the configuration of the control unit.

[0042] An operation panel 43 is connected to the control unit 34 as an input side, while the burners 19, 19, 37, the lifting mechanism 8, the fire door 23, and the opening / closing floor 38 are connected to the control unit 34 as an output side.

[0043] The operation panel 43 has a start button for starting the cremation process, a forced stop button for terminating the process midway, and a display unit that displays various information about the cremation equipment, such as the temperature inside each of the main combustion chambers 2,2.

[0044] The control unit 34 is configured to execute an ignition process for igniting each burner 19, 19, 37, a swing process for swinging each burner 19, 19, 37, an extinguishing process for extinguishing each burner 19, 19, 37, an adjustment process for adjusting the output of each burner 19, 19, 37, an ascent process for raising the lifting mechanism 8, a descent process for lowering the lifting mechanism 8, an opening process for raising the fire door 23, a closing process for lowering the fire door 23, a blocking process for switching the open-close floor 38 from an open state to a closed state, and an opening process for switching the closed-close floor 38 from a closed state to an open state.

[0045] To explain the cremation process in detail, the process starts when the start button is pressed. First, the raising process is performed and the second incineration table 6 is positioned at a height in front of the entrance 7. Next, the door opening process is performed and the entrance 7 is opened. At this time, the cremated body 1 or the coffin 21 is placed on the placement surface of the second incineration table 6.

[0046] After the cremated body 1 or coffin 21 is placed, the lowering process is performed, and the first crematorium 6 is placed at a height in front of the entrance 7, and the cremated body 1 or coffin 21 is placed on the placement surface. After it is confirmed that the cremated body 1 or coffin 21 is placed on each crematorium 6, 6, the door closing process is performed and the entrance 7 is closed.

[0047] After it is confirmed that the entrance 7 is closed, a closing process is carried out, and the opening 18 of the upper structure 16 is closed by the opening / closing floor 38 which has been switched to the closed state.

[0048] Then, the ignition process is performed, and the cremated body 1 is incinerated by each burner 19, 19, 37, and the re-burning process is performed in the re-burning chamber 3. The rocking process is performed as appropriate when there is a bias in the heating area, and the adjustment process is performed as appropriate so that the internal temperatures of each main combustion chamber 2, 2 and the re-burning chamber 3 are kept at 800 ° C to 1000 ° C.

[0049] When the incineration and re-burning processes are completed, the extinguishing process is performed. After it is confirmed that each incineration rack 6, 6 has been cooled to a temperature at which it can be removed, the door opening process is performed, and the cremated body 1 placed on the first incineration rack 6 is removed through the entrance 7. Next, the lifting process is performed, and the cremated body 1 placed on the second incineration rack 6 is similarly removed.

[0050] After each cremated body 1,1 is removed, the door is closed. This completes the cremation process.

[0051] According to the cremation equipment configured as described above, multiple cremated bodies 1,1 can be transported into the cremation chamber 2,2 through a single entrance / exit 7 and incinerated in parallel, so that the incineration work of multiple cremated bodies 1,1 can be carried out more efficiently.

[0052] Next, the difference between the above-mentioned embodiment and another embodiment of the present invention will be described with reference to Figures 6 to 8. Figure 6 is a side cross-sectional view of a cremation facility according to another embodiment of the present invention, Figure 7 is a side cross-sectional view showing the state in which the cremation furnace is raised by the lifting mechanism, and Figure 8 is a block diagram showing the configuration of the smoke exhaust treatment of the cremation facility shown in Figure 6.

[0053] The cremation equipment of the above-mentioned embodiment was configured to include two main combustion chambers 2, 2 arranged vertically side by side in the crematorium 4, a reburning chamber 3 arranged directly above them, and a lifting mechanism 8 provided in the crematorium 4. However, the cremation equipment of this embodiment has a space S1 formed by being surrounded by an insulating wall 44, a single main combustion chamber 2, and a reburning chamber 3 arranged directly above it, and is equipped with multiple crematoriums 4, 4 housed in the space S1, and a lifting mechanism 8 arranged below the crematorium 4. The crematoriums 4, 4 are arranged vertically side by side, and the lifting mechanism 8 is configured to raise and lower the multiple crematoriums 4, 4 as a whole.

[0054] In addition, this embodiment differs from the above-described embodiment in that the entrance / exit 7 is formed as an opening in the insulating wall 44 toward the front, that each main combustion chamber 2,2 is also provided with a separate entrance / exit 7,7 and fire doors 23,23, and that the entrances to the smoke exhaust duct 39 are provided separately in the reburning chambers 3,3 of both crematorium furnaces 4,4, and that the flow paths are configured to merge halfway through.

[0055] According to the cremation equipment configured as described above, the lifting mechanism 8 is positioned outside the crematorium furnace 4, so that the lifting mechanism 8 is not exposed to high temperatures during the incineration process, thereby extending its service life. In addition, since the structure of the opening and closing floor 38 is omitted, a simpler structure can be achieved.

[0056] Next, a different embodiment of the present invention will be described with reference to Fig. 9. Fig. 9 is a side cross-sectional view of a cremation facility according to another embodiment of the present invention. This embodiment is equipped with a single main combustion chamber 2 and a support frame 46 arranged in the main combustion chamber 2 and to which multiple incineration stands 6,6 are attached and supported, and the lifting mechanism 8 is configured to lift and lower the support frame 46 together with the multiple upper and lower incineration stands 6,6 attached and supported thereto.

[0057] The support frame 46 is formed in a box shape and has a plurality of storage spaces S2, S3 arranged side by side in the vertical direction. The incineration stands 6, 6 are arranged in each of these storage spaces S2, S3 and are detachably attached to the support frame 46 by mounting members.

[0058] According to the cremation equipment configured as described above, the main combustion chamber 2 is a single unit, which allows for a simpler structure. In addition, the lifting mechanism 8 is designed to lift and lower only the support frame 46 and the incineration platform 6, and there is no need to lift and lower heavy objects such as the main combustion chamber 2, which reduces the load on the lifting mechanism 8.

[0059] In the above example, two incineration stands 6 are arranged vertically, but three or more incineration stands 6 may be arranged vertically. These three or more incineration stands 6 arranged vertically are raised and lowered together in the main combustion chamber 2 by the lifting mechanism 8. [Explanation of symbols]
