Japanese Unexamined Patent Publication No. 2008-256237

Since the carcass P of the pet animal contains a large amount of water and fat, as described above, the crematorium R on which the carcass P is placed is placed on the pair of mounting portions 83, 83 made of the tube material of the support base 82. In the crematorium 80, in which air is supplied to the vicinity of the body P from the air outlets 83a of the pair of mounting portions 83, 83, the body P of the pet animal to be cremated came out. Moisture and fat are dropped from the grate R, and air is not supplied to the lower sides of the mounting portions 83, 83, so that the fat accumulated at the bottom of the cremation chamber 81 is incompletely burned and a foul odor is generated. There's a problem.

Further, in the crematorium 80 in which air is not supplied to the lower side of the pair of mounting portions 83, 83, the members on the lower side of the pair of mounting portions 83, 83 are exposed to the high temperature combustion gas. It is necessary to make it heat-resistant, and there is also a problem that the member cost becomes high.

Therefore, an object of this invention is to provide a pet crematorium that does not generate a foul odor and does not require the lower member of the mobile hearth on which the pet's body is placed to have heat resistance specifications.

In order to solve the above problem, the device according to claim 1 is a pet mortar furnace provided with a mobile hearth on which the body of the pet to be burial is placed and a combustion chamber for accommodating the mobile hearth in and out. The mobile hearth has a tray shape in which the peripheral wall rises from the peripheral edge of the bottom wall, and the combustion chamber closes the opening for taking in and out the mobile hearth and the opening openable and closable. In a state in which the door and the air supply means for supplying air to the combustion chamber are provided, the mobile hearth is housed in the combustion chamber, and the opening is closed by the door, the combustion chamber is the mobile hearth. It is divided into an upper space on the upper side of the mobile hearth and a lower space blocked from the outside on the lower side of the mobile hearth, and is surrounded by the combustion chamber around the mobile hearth. A gap communicating the upper space and the lower space is formed in the lower space, and the air supply means supplies air to the lower space, and the air supply means supplies the air to the lower space. The air is provided for a pet mortuary furnace characterized in that the air is sent to the upper space through a gap formed around the mobile hearth.

The device according to claim 2 is the pet crematorium according to claim 1, wherein the air supply means has an air supply header installed along the wall surface of the combustion chamber in the lower space. The air supply header is characterized in that a large number of air discharge holes for blowing air in the lateral direction with respect to the lower space are formed.

Further, the device according to claim 3 is the pet crematorium according to claim 1 or 2, wherein the mobile hearth is housed in the combustion chamber and pulled out from the combustion chamber. It is characterized in that it is provided with holding means for holding each at the drawer position.

As described above, in the pet crematorium devised according to claim 1, since the mobile hearth has a tray shape in which the peripheral wall rises from the peripheral edge of the bottom wall, the pet crematorium is released from the body of the pet to be cremated. Since the water and fat are not accumulated in the mobile hearth and dropped on the bottom of the combustion chamber, the fat and the like from the pet's body P can be surely burned and the generation of foul odor is prevented. be able to.

Further, in a state where the mobile hearth is housed in the combustion chamber and the opening is closed by a door, the combustion chamber is blocked from the upper space on the upper side of the mobile hearth and the outside on the lower side of the mobile hearth by the mobile hearth. In addition to being partitioned into the lower space, a gap is formed around the mobile hearth that communicates the upper space and the lower space with the combustion chamber, and the air supplied to the lower space by the air supply means. Is sent to the upper space through the gap formed around the mobile hearth, so there is no need to separately form an air flow path that communicates between the upper space and the lower space, and the structure of the furnace having a combustion chamber can be constructed. The effect of simplification can be obtained.

Further, since the air supplied to the lower space by the air supply means is sent to the upper space through the gap formed around the moving hearth, the high-temperature combustion gas does not flow into the lower space and moves. Since the members arranged on the lower side of the hearth are less likely to be exposed to high-temperature combustion gas, it is not necessary to make those members heat-resistant specifications, the cost of the members can be suppressed, and the non-combustion gas moves downward. Since it is not filled and the fat of the body can be reliably burned, the combustion efficiency is also improved.

Further, in the pet crematorium of the invention according to claim 2, the air supply means has an air supply header installed along the wall surface of the combustion chamber in the lower space, and the air supply header has an air supply header in the lower space. On the other hand, since a large number of air discharge holes that blow out air in the lateral direction are formed, the air supplied to the lower space is uniformly sent to the upper space through the gap at the peripheral edge of the mobile hearth, causing uneven cremation on the body. In addition to being less likely to occur, the effect of being able to uniformly cool the lower space can be obtained.

For example, in a mobile crematorium with a pet crematorium loaded on a vehicle, it may be necessary to perform the crematorium while parked on a slope. In such a case, when moving the hearth in and out of the combustion chamber, There is a problem that the mobile hearth moves naturally toward the lower side of the slope, but in the pet crematorium of the invention according to claim 3, the mobile hearth is housed in the combustion chamber at a predetermined storage position. And because it is equipped with holding means to hold each in the predetermined drawer position pulled out from the combustion chamber, when the crematorium with the mobile crematorium loaded on the vehicle must be parked on the slope. In addition, the mobile hearth can be reliably held in the accommodation position and the drawer position, the workability of the crematorium is improved, and when the mobile hearth is moved while being housed in the combustion chamber, the mobile hearth is specified. By holding the crematorium in the accommodation position, the mobile hearth does not move in the combustion chamber due to the shaking of the mobile crematorium while the mobile crematorium is running, and the components of the pet crematorium are not easily damaged.

In this state, when the operating member 63 is rotated to engage the locking claw 62 with the locked portion 65, the moving hearth 3 is held at the drawer position.

Therefore, for example, even when the cremation work is performed with the mobile cremation vehicle loaded with the pet cremation furnace 1 loaded on the vehicle on a slope, the holding means is used when the mobile hearth 3 is taken in and out of the primary combustion chamber CC1. By holding the mobile hearth 3 in the accommodation position or the drawer position, respectively, the mobile hearth 3 does not naturally move toward the lower side of the slope, and the workability of the cremation work is improved. Further, such a mobile crematorium travels (moves) with the mobile hearth 3 housed in the primary combustion chamber CC1. At that time, the mobile hearth 3 is held in a predetermined storage position. By doing so, the mobile hearth 3 does not move in the primary combustion chamber CC1 due to the shaking of the mobile crematorium during traveling, and the components of the pet crematorium 1 are not easily damaged.

In the pet burial furnace 1 configured as described above, as described above, in a state where the mobile hearth 3 is housed in the primary combustion chamber CC1 and the opening 17 is closed by the door 18, the combustion gas is in the primary combustion chamber CC1. As shown by the arrow in FIG. 4, the primary combustion chamber CC1 has the upper space US on the upper side of the mobile hearth 3 and the lower part of the mobile hearth 3 by the mobile hearth 3 without leaking to the outside from the lower part of the mobile hearth 3. It is divided into a lower space DS that is cut off from the outside on the side, and a gap that communicates the upper space US and the lower space DS is formed between the mobile hearth 3 and the primary combustion chamber CC1. Since air is supplied to the lower space DS via the air supply header 13, the air supplied into the lower space DS from the air outlet hole 13a of the air supply header 13 is constantly moving to the hearth. It is pushed up to the upper side of 3 and sent to the upper space US through the gap at the peripheral edge of the mobile hearth 3.

Therefore, the iron plate covering the front and rear surfaces of the mobile hearth 3, the lower portions of both side surfaces, and the peripheral edge of the bottom surface, the support roller 14 supported by the floor surface of the base member 10a, and the auxiliary roller supported by the mobile hearth 3. Since 54 is not easily exposed to high-temperature combustion gas and it is not necessary to make these members heat-resistant specifications, the cost of members can be suppressed, and the non-combustion gas does not fill downward, so that the fat of the body P Etc. can be reliably burned, so that the combustion efficiency is also improved.

Further, in the pet burial furnace 1, as described above, the air supply means for supplying air to the lower space DS of the primary combustion chamber CC1 is provided along the wall surface of the primary combustion chamber CC1 in the lower space DS. The air header 13 is provided, and a large number of air discharge holes 13a for blowing air laterally with respect to the lower space DS are formed in the air supply header 13, so that the air supplied to the lower space DS moves.

Further, as described above, the pet burial furnace 1 is held in a substantially horizontal state without the drawer end side of the mobile hearth 3 pulled out from the opening 17 of the refractory container 10b tilting downward. When moving the mobile hearth 3 in and out of the primary combustion chamber CC1, it is not necessary to use an external support member that supports the mobile hearth 3 pulled out from the opening 17 of the primary combustion chamber CC1 outside the refractory container 10b. Since the moving hearth 3 moves while the auxiliary roller 54 in contact with the lower surface of the support plate 19 rolls, the moving resistance of the moving hearth 3 is small, and the movement resistance of the moving hearth 3 is small with respect to the refractory container 10b (primary combustion chamber CC1). The work of putting in and taking out the mobile hearth 3 can be performed smoothly and easily.

In the pet crematorium 1 described above, the support roller 14 with a brim and the auxiliary roller 54 are used, but a rolling member such as a ball roller can also be used, and the support roller 14 with a brim can be used. When a ball roller is used instead of the above, it is necessary to provide a guide member that regulates the moving direction of the moving hearth 3.

Further, in the pet cremation furnace 1 described above, the support plates 19 with which the auxiliary rollers 54 come into contact are attached to the exterior plates 15a on both sides of the refractory container 10b, but they can also be attached to the upper surface of the air supply header 13. ..

Further, in the above-mentioned pet mortuary furnace 1, the moving hearth 3 is movably supported in the front-rear direction by a plurality of support rollers 14 with flanges arranged on the bottom plate 11 of the base member 10a. For example, as in the furnace 2A shown in FIGS. 7 to 9, the wheels 14a are attached to the iron plate portion on the bottom surface of the hearth body 51, and the wheels 14a are guided by the pair extending in the front-rear direction. The rail 14b may be arranged on the bottom plate 11 of the base member 10a, and the moving hearth 3A may be taken in and out of the primary combustion chamber CC1 along the pair of rails 14b.

Further, in the above-described embodiment, the mobile hearth 3 is provided at the rear end of the mobile hearth 3 so that an external rail or the like does not need to be used separately to move the mobile hearth 3 in and out of the primary combustion chamber CC1. By bringing the pair of left and right auxiliary rollers 54 into contact with the lower surfaces of the pair of left and right support plates 19 of the fireproof container 10b, the drawer end side of the mobile hearth 3 is prevented from tilting downward, but this is limited. If the lower space DS of the primary combustion chamber CC1 can be cut off from the outside while the mobile hearth 3 is housed in the primary combustion chamber CC1, the mobile hearth 3 is provided with respect to the primary combustion chamber CC1. When taking in and out, an external support member such as a rail that supports the mobile hearth 3 drawn out from the opening 17 of the primary combustion chamber CC1 outside the fireproof container 10b may be used.

Further, in the above-described embodiment, in order to uniformly supply air to the lower space DS of the primary combustion chamber CC1, lateral to the lower space DS installed along the wall surface of the primary combustion chamber CC1 in the lower space DS. An air supply header 13 having a large number of air discharge holes 13a for blowing air in the direction is provided, but the air supply pipe 41a for primary combustion is connected to the lower part of the primary combustion chamber CC1 without providing such an air supply header 13. The air may be directly supplied to the lower space DS.

Further, in the above-described embodiment, the combustion chamber is divided into the primary combustion chamber CC1 and the secondary combustion chamber CC2 by the partition wall 16, and the combustion exhaust gas generated in the primary combustion chamber CC1 is completely heated and decomposed in the secondary combustion chamber CC2. However, the present invention is not limited to this, and it is not always necessary to provide a secondary combustion chamber as long as it can be completely burned in one combustion chamber.
