Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention relates to a carriage cooling device for cooling a carriage in a furnace conveyed from a cremation furnace into a bone collecting chamber after completion of cremation.

(Prior Art) Conventionally, when the bereaved family collects bones from the trolley in the furnace that was transported from the cremation furnace to the bone collection chamber after the cremation process, the dolly in the furnace is placed in the vault. It is naturally cooled in the cremation furnace for a while before being transported to.
Further, when a front chamber is provided, the in-reactor carriage is transferred to the front chamber before being transferred to the bone-accommodating chamber and naturally cooled in the front chamber for a while.

However, in the case where the in-core trolley is cooled in the cremation furnace, there is a problem that the cooling efficiency is poor and the cooling time of the in-core trolley takes a very long time. Further, even when the truck inside the furnace is cooled in the front chamber, there is a limit to the temperature reduction in a short time, and there is a problem that the cooling time also takes a long time.

Therefore, in the past, a pair of bogie cooling protectors were erected on the floor of the bone collecting chamber, and after the cremation, the in-core bogie was transported between these bogie cooling protectors, and then one bogie cooling protector was used to top the in-core bogie. There is a type in which the in-core truck is forcibly cooled by blowing air toward the surroundings and sucking air around the upper surface of the in-core truck from the other truck cooling protector.

(Problems to be solved by the invention) However, in such a configuration, air is blown from one of the bogie cooling protectors toward the periphery of the upper surface of the in-reactor bogie, so that the mass on the in-reactor bogie is reduced. There is a problem that light soot and the like are blown off, which makes the bone collecting work unsanitary and difficult.

The present invention has been made in view of the above circumstances. The purpose of the present invention is to reduce the cooling time of the trolley in the furnace and to make the bone collecting work hygienic and easy. To provide a device.

[Structure of the Invention] (Means for Solving the Problems) The gist of the present invention is to provide a pair of bogie coolings on the floor surface of the bone collection chamber, which is slightly higher than the upper surface of the furnace bogie mounted on the carrier bogie. The protectors are erected opposite to each other at appropriate intervals, and an exhaust passage for sucking air around the upper surface of the in-reactor bogie is provided in the bogie cooling protector, and an exhaust fan is provided at a portion communicating from the exhaust passage to the outside of the sac chamber. There is provided an exhaust device provided with the above, and an air supply device provided with an air supply fan is provided in a portion communicating from the outside of the bone collecting chamber to the inside of the bone collecting chamber.

(Function) Immediately after the cremation, the in-furnace trolley is placed on the carrier trolley to transfer it from the cremation furnace to each trolley cooling protector in the bone collection chamber, and then the air supply fan of the air supply device and the exhaust fan of the exhaust device are operated. As a result, the air outside the bone collecting chamber is sent into the bone collecting chamber through the air supply device, and the air around the upper surface of the trolley inside the furnace is discharged to the outside of the bone collecting chamber through the exhaust passage and exhaust device in each trolley cooling protector. Is discharged. As a result, convection hot air, light soot, and the like from the surface of the in-core truck are forcibly discharged to the outside of the sac chamber, and the in-core truck is forcibly cooled.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIGS. 1 and 2, the floor surface 1a in the bone collecting chamber 1 is slightly higher than the upper surface of the in-core truck 3 mounted on the electric carrier truck 2 and is substantially the same as the in-core truck 3 A pair of bogie cooling protectors 4 and 4 having a length are erected so as to face each other at appropriate intervals so as to be slightly wider than the lateral width of the carrier bogie 2. In addition, these cart cooling protectors 4 and 4 are
Tile is attached to the outer surface of concrete, or stainless steel is attached to the outer surface of the heat insulating material to give a good appearance.

In addition, inside the furnace cooling protectors 4 and 4, the in-core truck 3
Exhaust passages 5 and 5 for sucking air around the upper surface of the are provided. These exhaust passages 5 and 5 have air passages 6 and 6 whose lower ends communicate with the floor surface 1a, and the upper surfaces of the inner surfaces of the bogie cooling protectors 4 and 4 that are the same as or slightly higher than the upper surface of the in-core bogie 3. The air suction ports 7 and 7 are provided at positions along the longitudinal direction.

Further, a first muffler chamber 9, an exhaust fan 10, a second muffler chamber 11, and an exhaust gallery 12 are provided in an exhaust duct (not shown) at a portion communicating from the exhaust passages 5 and 5 to the outside of the skeleton chamber 1. An exhaust device 13 is provided. This exhaust system
One end of the exhaust duct 13 is communicated with the exhaust passages 5 and 5 on the floor surface 1a below the central portion in the longitudinal direction of the bogie cooling protectors 4 and 4.

And, in the part that communicates from the outside of the bone collecting chamber 1 to the inside of the bone collecting chamber 1,
Air supply louver 15 and air supply fan in the air supply duct (not shown)
There is provided an air supply device 19 including 16, a third silencing chamber 17, and a blow-off air control port 18. The blow-off air inlet 18 of the air supply device 19 is provided for each of the truck cooling protectors 4 and 4 in the bone collecting chamber 1.
It opens towards.

Immediately after completion of the cremation, the in-furnace trolley 3 is placed on the carrier trolley 2 and pulled out from the inside of the cremation oven (not shown), and then conveyed between the trolley-cooling protectors 4 and 4 in the bone collecting chamber 1. , The air supply fan 16 of the air supply device 19 and the exhaust device 13
Operate the blower 10. Then, the air outside the skeleton chamber 1 is blown out from the air outlet 18 of the air supply device 19 and the in-reactor trolley 3 in the sac chamber 1
The air around the upper surface of the in-reactor bogie 3 is sent from the exhaust gallery 15 to the outside of the sacral chamber 1 through the exhaust passages 5 and 5 in each bogie cooling protector 4 and 4, and the exhaust device 13. Is discharged. As a result, the hot air, light dust, and the like that convection from the surface of the in-core truck 3 can protect each truck cooling protector 4,
4 is forcibly exhausted from the air intake ports 7, 7 on the inner surface of 4, and the in-core truck 3 is forcibly cooled.

By the way, in this type of device, since the bereaved family and the like need to confirm the remains on the in-core trolley 3 and collect them, the upper surface of the in-core trolley 3 must be open. Further, according to this embodiment, the air suction ports 7, 7 of the truck cooling protectors 4, 4 opening the air around the upper surface of the in-core truck 3 in the vicinity thereof.
Since the hot air convection from the surface of the in-core trolley 3 does not rise, it is forcibly exhausted directly to the outside of the sac chamber 1 so that the in-core trolley 3 is placed in the cremation furnace or in the front chamber (not shown). The cooling efficiency is remarkably better than that in the case of natural cooling, so that the cooling time of the in-core carriage 3 can be significantly shortened. Further, even though the upper surface of the in-core trolley 3 is open, even if the bereaved family or the like approaches the upper surface of the in-core trolley 3, the bereaved family or the like can be safely protected from hot air. Further, since the air around the upper surface of the in-core truck 3 is sucked into the air suction ports 7 and 7 in this way, it is possible to prevent the soot and the like having a small mass on the in-core truck 3 from being blown off, and therefore the air is collected. Bone work is hygienic and work is easy. Moreover,
Immediately after completion of the cremation, the in-reactor trolley 3 is placed between the protectors 4 and 4 of the cremation chamber 1 between the protectors 4 and 4 and the bereaved family can squeeze the in-reactor trolley 3 by forced air cooling. It is possible to quickly collect the bones and collect the bones, and thus it is possible to shorten the waiting time for the bereaved family. Further, by using the existing protector for protecting the bereaved family etc. from the high-temperature in-core trolley 3 during the bone collecting work, by providing the exhaust passages 5 and 5 therein,
The above effects are obtained, and therefore, it is not necessary to provide special cooling equipment such as a front chamber for cooling the truck 3 in the furnace, and the equipment is compact.

The present invention is not limited to the above-described embodiment, and the exhaust device 13 may include a dust collector, for example. Of course, various modifications can be made without departing from the scope of the present invention.

[Advantages of the Invention] As described above, according to the present invention, the air around the upper surface of the in-core truck is sucked in through the exhaust passage of the truck cooling protector in the vicinity thereof. The hot air that is generated does not rise and is forcibly exhausted directly to the outside of the skeleton chamber, so the cooling efficiency of the in-core trolley is significantly improved, the cooling time of the in-core trolley can be greatly shortened, and the upper surface of the in-core trolley is open. Despite this, the bereaved family can be safely protected from the heat even if the bereaved family approaches the upper surface of the furnace trolley. Also, since the air around the upper surface of the in-core truck is sucked in through the exhaust passage in this way,
It is possible to prevent light soot and dust on the bogie in the furnace from being blown off, so that bone collecting work is hygienic and the work is easy.
