That is, 1 is a cremation furnace body composed of refractory bricks, etc., 2 is a main combustion chamber, and 3 is a re-combustion chamber. A combustion burner 4 is provided at the rear of the main combustion chamber 2, and an opening / closing door 6 is provided at an entrance 5 at the front. An exhaust port 7 communicating with the re-combustion chamber 3 is provided on an upper wall of the main combustion chamber 2 near the entrance / exit 5, and a smoke exhaust port 8 is provided in the re-combustion chamber 3.

A guide rail 9 is provided at the bottom of the main combustion chamber 2 in the front-rear direction, and a tray 10 that can be inserted into and removed from the entrance 5 is slidably mounted on the guide rail 9.

A casket mounting table 11 projecting inward is provided on both left and right side walls forming the main combustion chamber 2, and the casket mounting table 11 is supported by both side edges of a casket 12 containing a body in the longitudinal direction. It is supposed to be done. Therefore, spaces are formed at the top, bottom, left and right, and front and rear of the casket 12, so that the flame from the combustion burner 4 is spread over the entire casket 12.

A casket supporting member 13 is provided below the casket mounting table 11 and above the tray 10. The casket supporting member 13 is formed of a rod made of a heat-resistant material, and two coffin supporting members are provided in parallel with each other in the front-rear direction of the main combustion chamber 2. It is fixed on the brick. In addition, 14 and 15 are inlets for secondary air. ,

According to the cremation furnace configured as described above, the casket 12 containing the body is introduced into the main combustion chamber 2 from the doorway 5 by the cremation carriage or the like, and the casket 12 is supported by the casket mounting table 11. When the open / close door 6 is closed and the combustion burner 4 is ignited, the burner flame generated from the combustion burner 4 is injected toward the front of the main combustion chamber 2, but the exhaust port 7 is provided on the upper wall. Therefore, the burner flame rises toward the exhaust port 7, and the casket 12 supported by the casket mounting table 11 is cremated.

[0009]

[Problems to be solved by the device]

 However, in the conventional cremation furnace configured as described above, as the cremation progresses, the casket 12 supported by the casket placing table 11 burns down and the body is supported by the two casket supporting members 13. Since the two casket support members 13 are at the same height, the body is supported horizontally. In other words, even if the combustion burner 4 is adjusted in the vertical direction to some extent, the body and the direction of the burner flame are parallel to each other, and the burner flame cannot be concentrated on the waist and abdomen of the body, which are the most difficult to burn. Therefore, cremation time is long and fuel consumption is high.

This invention was made in view of the above circumstances, and its purpose is to bring the most inflammable waist and abdomen of the body closer to the burner flame as the cremation progresses. It is an object of the present invention to provide a cremation furnace that can face a flame, shorten cremation time, and reduce fuel consumption.

[0011]

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. However, the same components as those of the related art will be denoted by the same reference numerals and description thereof will be omitted.

As shown in FIGS. 1 and 2, the width of the main combustion chamber 2 of the cremation furnace body 1 made of refractory bricks in the left-right direction is such that the upper portion is the wide portion 2a and the lower portion is the narrow portion 2b. The left and right side walls of the main combustion chamber 2 are formed with inclined surfaces 21 so that the width gradually narrows from the wide portion 2a to the narrow portion 2b.

First and second casket supporting members 22 and 23 are provided in the middle of the inclination of the inclined surface 21 so as to be separated from each other in the front-rear direction of the main combustion chamber 2. As shown in FIG. 3, the first and second casket support members 22 and 23 are made of a heat-resistant material, for example, a rod-shaped body made of ceramic or the like. Support legs 25 are provided that project downward at a right angle.

A pivotal support portion 26 extending outward is provided on one of the support legs 25, and the pivotal support portion 26 is rotatably supported by a bearing 27. On the other side of the support leg 25, there is provided a projecting portion 28 which further projects upward from a pivotally supporting portion 26 rotatably supported by a bearing 27.

Further, the protruding portions 28 of the first and second casket supporting members 22 and 23 are connected to one connecting rod 29 by a pivot pin 30, and the connecting rod 29 is connected to an air cylinder 31 as a driving means. It is connected.

The bearings 27 at both ends of the first and second casket supporting members 22 and 23 thus configured are fixed to a fixing portion 21 a provided in the middle of the inclined surface 21 of the main combustion chamber 2. Therefore, the rod-shaped support portion 24 is installed in the width direction of the main combustion chamber 2.

The connecting rod 29 extends to the rear of the main combustion chamber 2, and the air cylinder 31 is provided outside the rear of the cremation furnace body 1. The first and second casket supporting members 22 and 23 can be rotated by moving the connecting rod 29 forward and backward by the air cylinder 31.

That is, when the supporting legs 25 of the first and second casket supporting members 22 and 23 are standing in a vertical state, the casket 12 has a predetermined height in the main combustion chamber 2 and a predetermined longitudinal direction. When the support leg 25 is held in the position and pivoted rearward (backward of the main combustion chamber 2) about the pivotal support portion 26 as a fulcrum, the height of the casket 12 becomes low, and the combustion burner 4 can be approached.

The combustion burner 4 is supported by a bracket 32 provided on the rear wall of the cremation furnace main body 1 so as to be rotatable in the vertical direction, and is driven by an air cylinder 33. Then, the flame injection part 4a of the combustion burner 4 can be moved in the vertical direction in the main combustion chamber 2 so that the burner flame can be directed in any vertical direction. A monitoring window 34 is provided near the combustion burner 4 to monitor the inside of the main combustion chamber 2.

The casket 12 containing the body is introduced into the main combustion chamber 2 through the doorway 5 by a cremation carriage or the like, and the casket 12 is supported by the rod-shaped support portions 24 of the first and second casket support members 22 and 23. When the open / close door 6 is closed and the combustion burner 4 is ignited, the burner flame generated from the combustion burner 4 is injected toward the front of the main combustion chamber 2 to cremate the casket 12.

When the connecting rod 29 is gradually retracted by the air cylinder 31 while monitoring the state of the casket 12 through the monitoring window 34 during the cremation, that is, when the cremation has progressed to a certain extent, the first and second casket supports are performed. The members 22 and 23 rotate rearward (toward the inner side of the main combustion chamber 2) with the pivot portion 26 as a fulcrum.

Therefore, as shown by the chain double-dashed line in FIG. 4, the height of the casket 12 supported by the rod-shaped support portions 24 of the first and second casket support members 22 and 23 is reduced, and the combustion burner is also reduced. Move in the direction of approaching 4. At the same time, when the combustion burner 4 is rotated by the air cylinder 34 to move the flame injection part 4a of the combustion burner 4 downward in the main combustion chamber 2, the burner flame is transferred to the casket 12 near the tray 10. It allows you to concentrate toward your body and strengthens the burning power of the body's most inflammable waist and abdomen. After the cremation is completed, the ashes are received in the saucer 10 together with the ashes.

In this way, the casket 12 of the main combustion chamber 2 is moved as the cremation progresses, and the burner flame is concentrated on the most inflammable waist and abdomen of the body, so that the entire body is uniformly and in a short time. Can be cremated. Further, the operation is facilitated by rotating the first and second casket supporting members 22 and 23 supporting the casket 12 by the air cylinder 31 provided outside the cremation furnace main body 1.

In the above embodiment, the first and second casket supporting members 22 and 23 are connected by one connecting rod 29 and are simultaneously rotated by the air cylinder 31. As shown in FIG. 5, an air cylinder in which connecting rods 35 and 36 are independently connected to the protruding portions 28 of the first and second casket supporting members 22 and 23, respectively, and these connecting rods 35 and 36 are independently provided. It may be connected to 37 and 38.

With this configuration, the first and second casket supporting members 22 and 23 can be independently rotated, and the first casket supporting member 22 can be rotated in the upright position. By rotating the casket supporting member 23 of No. 2, it is possible to incline the casket 12 toward the combustion burner 4 side as the cremation proceeds.

Further, in the above embodiment, the air cylinder 31 or 37, 38 is used as the means for rotating the first and second casket supporting members 22, 23, but the screw rod is rotated by the motor. A nut that meshes with the screw rod may be provided on the protruding portion 28 for rotation, or a handle or the like may be provided on the connecting rod 29 or 35, 36 for manual rotation.
