Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a cremation furnace.

[0002]

2. Description of the Related Art A conventional cremation furnace is provided with a burner substantially at the same height as the coffin or slightly above the coffin, and employs a method of burning a corpse from the upper surface side. Workers operating the crematorium,
The burner's swing angle is adjusted so that the flame hits the flame-retardant directly by looking into the main combustion chamber, or the flame-retardant is moved to the position where the flame hits by the operation rod, and the body is completely incinerated. Was.

[0003] When cremated, a temperature difference occurs between the upper and lower portions of the main combustion chamber due to the rising action of hot air, and the furnace body is distorted and damaged by the temperature difference. When using a crematory furnace many times a day, it was desirable to cool the furnace to a certain extent in order to extend the life of the furnace, but to increase the life of the furnace, In some cases, the remains must be incinerated, in which case the spacing is insufficient and the other remains are cremated while the furnace is hot, increasing the temperature difference between the upper and lower parts of the main combustion chamber. , The furnace body distortion is promoted,
The life is shortened at a stretch. On the other hand, if the burner power is increased and the incineration time of the body is shortened, it is possible to secure a sufficient interval, but the fuel efficiency deteriorates and moreover, it occurs in the main combustion chamber during one use. The temperature difference became larger than in the case of normal burner output, which led to a shortened life of the furnace body.

[0004]

SUMMARY OF THE INVENTION The present invention has been developed in view of the above circumstances, and an object of the present invention is to provide a cremation furnace capable of shortening the burning time of a corpse and extending the life of the furnace body. To provide.

[0005]

In the cremation furnace of the present invention, the furnace body is provided with a roster for mounting a coffin at an intermediate height of the main combustion chamber, and the upper space and the lower space of the main combustion chamber are provided by a through hole provided in the roaster. The space is communicated, a pair of burners are provided on the rear wall in a state in which flames are separately sprayed to the upper space and the lower space, and a bone receiving means disposed below the roster is provided so as to be able to enter and exit the furnace body. It is characterized by the following.

[0006] "Rostor" means a member provided with a passage communicating between the upper space and the lower space of the main combustion chamber. Examples of specific shapes include a lattice shape and a fence shape.
"Bone receiving means" means a means for receiving bones when bones naturally fall from the entrance of Rostor or when an operator forcibly drops bones remaining on Rostor, Typical examples include a dish shape and a cart shape.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As shown in FIG. 1, a first example of a cremation furnace of the present invention is that an inner space of a furnace body 1 is vertically divided by a partition wall 2 provided at an intermediate height, and a coffin 3 is provided on a lower side. Is a main combustion chamber 4 for cremating, the upper side is a reburning chamber 5 for burning unburned gas generated from the main combustion chamber 4, and a flue 6 connecting the two combustion chambers 4, 5 is formed of a partition wall 2 and a rear wall 7. Opened in the middle, at the intermediate height position of the main combustion chamber 4, there is provided a roster 8 on which the coffin 3 is placed. The rostr 8 partitions the main combustion chamber 4 into an upper space 4 a and a lower space 4 b, and a through hole 9 provided in the rostr 8. Upper space 4
a communicates with the lower space 4b. Window holes 10 are opened in the rear wall 7 above and below the rostrum 8, and a burner 11 is swingably provided in each window hole 10, and the bottom wall 12 is provided with a bone support just below the position where the coffin 3 is placed. A bone tray as means 13 is arranged. In the front wall 14, an entrance 15 of the coffin is opened at the upper position of the main combustion chamber 4, and an entrance 16 of the bone tray 13 is opened on the lower side, and the entrance 15 for the coffin is opened and closed by the first door 17, The tray entrance 16 is openably closed by a second door 18. Note that a burner 11 is also provided on the rear wall 7 at the height of the reburning chamber 5.

The rostr 8 used here has a plurality of support rods 20 laid side-by-side at right and left side walls 19, 19 of the furnace body 1 at intervals in the front-rear direction. The space between them becomes a passage 9 and the upper surface of each support rod 20
The casket 3 is easy to put in according to the bottom of. The support rod 20 is made of fire-resistant fired brick.

A second example of the cremation furnace of the present invention is characterized in that, as shown in FIG. 2, a pipe 21 is used in place of the supporting rod 20 which constitutes the roaster 8. The pipe 21 is provided so as to protrude laterally from between the left and right side walls 19, 19, and allows liquid or gas to pass through the inside during cremation for cooling.
Avoid burning. Since the pipe 21 has a circular cross section, it naturally falls as if the bone slides down. In addition,
Since the furnace body 1 used here has the flue 6 bent, it is difficult for the noise of the main combustion chamber 4 to be transmitted to the reburning chamber 5.

In the third example of the cremation furnace of the present invention, as shown in FIG. 3, a truck is used as the bone receiving means 13, and a rail 22 for sliding the truck 13 is laid on the bottom wall 12. An air outlet 23 for sending cool air is opened in the rear wall 7. By using the trolley 13, the operation of pulling the bone out of the furnace body 1 can be performed quickly. The furnace body 1 used in the third example is called a co-current type, and a flue 6 is provided between the main combustion chamber 4 and the re-combustion chamber 5.
With a structure interposed substantially parallel to both combustion chambers 4 and 5, the hot air moved to the front wall 14 side by the injection of the burner 11
It rises as it is and enters the flue 6. In addition,
The furnace body 1 used in the first example and the second example is called a countercurrent type, in which the hot air that has moved to the front wall 14 returns to the rear wall 7 side (burner side), and then rises and the flue 6 It is something that invades.

[0011]

According to the cremation furnace of the present invention, the flame from the burner reaches the upper space and the lower space of the main combustion chamber separately.
Since the ostre carrying the coffin is provided with an opening communicating the upper space and the lower space, the heat of the flame that reaches the lower space rises to the upper space via the opening, and the body is moved from both upper and lower sides. It is possible to create an ideal burning state for incineration, and as a result, it is possible to incinerate the corpse in a short time with little work to expose the flame-retardant to the flame. In addition, since the fuel is combusted using the heat-raising effect skillfully, the fuel is effectively used. Furthermore, since the flames are separately injected into the upper space and the lower space, the main combustion chamber warms up approximately evenly, and the temperature difference between the two spaces becomes smaller as compared with the conventional structure, and as a result, the distortion of the furnace body is reduced. Since the size is reduced, the life of the furnace body is extended. In addition, when the corpse is burned, if the bone falls naturally from the opening of the rostrum, or if the bone remaining on the rostrum is forcibly dropped, the bone will fall into the bone receiving means disposed below the rostol. Since the bones are stored in the bone, the bones can be easily collected.
