Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simple type of incinerator for incinerating trash such as household garbage and excrement at home and the apparatus therefor.

[0002]

2. Description of the Related Art As a device of this type, a special table 2-50
There is a so-called "incinerator with catalyst container" described in No. 0820. In this device, an annular electric heating coil is arranged around the upper part of the ash pan that collects waste, and when excrement is dropped into the ash pan through the center of the annular electric heating coil, the annular electric heating coil heats up. , This heat incinerates the excrement in the ash pan. The vaporized gas generated by this incineration is sucked into a catalyst provided along the outer periphery of the annular electric heating coil, and the odor is removed by this catalyst before being discharged.

[0003]

However, in the above-mentioned conventional apparatus, since the annular electric heating coil is arranged above the ash pan for storing the excrement, the excrement in the ash pan can be efficiently disposed. Could not be incinerated. That is, since the annular electric heating coil has an annular shape, the ash pan is disposed below the coil even though the inner side of the coil is heated most, so that the excrement in the ash pan efficiently heats. It could not be said that it was burned and incinerated.

[0004] Therefore, an object of the present invention is to more efficiently incinerate garbage such as household garbage and excrement.

[0005]

In order to solve the above problems, in the present invention, a heater is provided on the upper surface of the housing.

A reflector can be arranged on the upper side of the reflector,
Furthermore, a flow path for vaporized gas can be formed.

Further, according to the present invention, the incineration of the filth is repeatedly performed, the incineration is repeated at the first set temperature for a predetermined number of times, and then the incineration is performed at least at the second set temperature higher than the first set temperature. It is configured to be performed once.

[0008]

According to the present invention, since the filth exists immediately below the heater in the heat radiation direction, the heat generated by the heater is effectively transmitted to the filth and efficiently heated to be incinerated.

In the case where the reflector is provided, the heat directed to the upper side of the heater is reflected downward by the reflector so that the amount of heat reaching the waste increases and the heat is more efficiently heated and incinerated. ..

If the flow path is provided above the reflector, the heat of the heater reaches the flow path to a considerable extent, so that vaporization of the vaporized gas passing through the path is promoted.

Further, according to the incineration method of the present invention, most of the waste is treated by repeating the incineration at the first set temperature a predetermined number of times, and the incineration at the higher second set temperature is performed. The remaining waste is processed.

[0012]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a sectional view showing an embodiment of the incineration processing apparatus according to the present invention. In the same figure, a casing composed of a pot 1 and a lid 2 is for accumulating filth. A reflector 3 is attached to the lower side of the lid 2, and a heater 4 is attached to the lower side of the reflector 3. In the terminal housing 5, each terminal 6 of the heater 4, a thermocouple 7a for measuring the temperature of the heater 4, and a thermocouple 7 for measuring the temperature inside the pot 1.
Terminals 8a and 8b of b are accommodated. Dirty suction pipe 9
Is partially bendable because the lid 2 is opened and closed, and is introduced into the pot 1 through the lid 2 to guide dirt to the bottom of the pot 1. The odor absorbing unit 10 is incorporated in the lid 2 and sucks vaporized gas generated from the waste in the pot 1 into the suction hole 1
The odor of the vaporized gas is removed from the exhaust gas 1 and the exhaust gas is exhausted from the exhaust hole 12.

The air adjusting hole 13 has a valve function, supplies necessary or appropriate air into the kettle 1 for efficient combustion, and causes the inside of the kettle 1 to be heated more than necessary as the temperature rises. When various dangerous conditions due to gas expansion etc. occur, air is released (depressurized). The chain block clasp 14 is used when hoisting the device described later.

The pot 1 and the lid 2 are cylindrical bodies as shown in FIG. 2, and are assembled by being fitted to each other. further,
Between the pair of L-shaped metal fittings 21 attached to the peripheral surfaces of the shuttle 1 and the lid 2 and between the other pair of L-shaped metal fittings 22 are tightened by the respective thumbscrews 23 and 24. The space between the lids 2 is sealed. The hook 1 and the lid 2 are not limited to the cylindrical shape, but may be various shapes such as a square tube shape.

The heater 4 is composed of two heaters 4a and 4b as shown in FIG. 2 (a). These heaters 4a, 4
By appropriately bending "b" and arranging it on the lower side of the lid 2, the area of heat radiation to the bottom side of the pot 2 is expanded and the most efficient heating is performed. Further, each end of each heater 4a, 4b, that is, a total of four ends is connected to each terminal 6 in the terminal housing 5.
Therefore, if a voltage is applied between the terminals 6 of the heaters 4a and 4b, the heaters 4a and 4b generate heat. Heater 4
The shape is not limited to the shape shown in FIG. 2A, and can be formed by three pieces 4a, 4b and 4c as shown in FIG.

The reflecting plate 3 above the heater 4 is a metallic disc having a smooth lower surface, and reflects the heat radiated upward from the heater 4 toward the bottom of the pot 1. Further, on the upper surface of the reflection plate 3, two spiral walls 31, 32 shown in FIG.
Are projected, and the disc 33 is attached to the upper side thereof. As a result, two spiral paths 34 partitioned by the two spiral walls 31 and 32 are formed between the reflection plate 3 and the circular plate 33. Further, the disc 33 is provided with the suction hole 11 communicating with the odor absorbing unit 10. Therefore, the room surrounded by the pot 1 and the lid 2 and the odor absorbing unit 10 are connected via the two spiral paths 34, 34 and the suction hole 11. Increasing the number of spiral walls 31 and 32 also increases the number of spiral paths 34.

The odor absorbing unit 10 has first and second catalyst housings 41 and 42 respectively housing various catalysts such as a honeycomb catalyst for removing the odor of vaporized gas,
The first and second heaters 43 and 44, and the first and second heaters
The thermocouples 45 and 46 are incorporated and an exhaust fan 47 is provided.

First and second catalyst housings 41, 42
As shown in FIG. 4, the honeycomb catalyst 51 and the like are housed, and a plurality of slits 52 for passing vaporized gas are provided on each of the left and right side walls. These slits 52 have an inclination that becomes lower inside so that the powder generated by the powdering of the catalyst 51 does not leak to the outside of the housings 41, 42. A binding lid 53 is provided on the upper side of the housings 41 and 42, and the catalyst 51 can be replaced by removing the binding lid 53.
When the catalyst 51 is actually replaced, the upper plate of the odor absorbing unit 10 is removed, and then the binding lids 53 of the first and second catalyst housings 41 and 42 are removed,
Each catalyst 51 will be exchanged.

The first heater 43 heats the vaporized gas sucked from the suction hole 11 and heats the catalyst 51 to a temperature at which the catalyst 51 in the first catalyst housing 41 sufficiently operates. It is for heating. The first thermocouple 45 is provided to measure the degree of heating by the first heater 43.

Similarly, the second heater 44 is for heating the vaporized gas and appropriately heating the catalyst 51 in the second catalyst housing 42. Also, the second thermocouple 4
6 is for measuring the degree of heating by the second heater 44. In addition, according to the detection value of the thermocouple 46, both housings 4
The thermocouple 45 can be eliminated because the degree of heating of the catalyst 51 in 1, 42 can be inferred.

The exhaust fan 47 has a built-in fan (not shown) and a motor 48 for rotating the fan. By the exhaust fan 47, the vaporized gas in the chamber surrounded by the kettle 1 and the lid 2 is guided through the spiral path 34 on the upper side of the reflection plate 3, the suction hole 11, and the first and second catalyst housings 41 and 42, The deodorized exhaust gas is discharged from the discharge hole 12.

The process for incinerating the waste with such a structure will be described below.

First, for example, excrement is guided to the pot 1 through the waste suction pipe 9 and stored therein.

Next, heating by the heater 4 is performed until the temperature measured by the thermocouple 7 reaches a preset temperature. As a result, the waste in the pot 1 is boiled and incinerated, and vaporized gas containing water, odor, etc. is generated.

At this time, in the odor absorbing unit 10, while the temperature is measured by the first and second thermocouples 45 and 46, the heating is appropriately performed by the first and second heaters 43 and 44, and the exhaust gas is exhausted. The fan 47 is operated to deodorize the vaporized gas and discharge it from the discharge hole 12.

FIG. 5 shows the above processing in a simplified manner. In the same figure, the thin solid line arrow shows the radiant heat from the heater 4, the thin dotted line arrow shows the heat reflected by the reflection plate 3, and the thick solid line arrow shows the path of the vaporized gas a.

As is apparent from FIG. 5, since the heater 4 is arranged immediately above the dirt, the dirt can be efficiently heated. Further, since the reflection plate 3 that reflects the upward radiant heat of the heater 4 downward is provided on the upper side of the heater 4, the filth is heated more efficiently.

Further, the spiral path 34 on the upper side of the reflection plate 3 is heated by the heater 4, so that the vaporized gas a passing through the spiral path 34 is further heated, and vaporization is promoted. Therefore, the heat radiated from the heater 4 is used without waste.

On the other hand, in the odor absorbing unit 10,
Since the heating is performed by the first and second heaters 43 and 44, not only the vaporization of the vaporized gas a is further promoted, but also the respective catalysts in the first and second catalyst housings 41 and 42 are 51 is set to an appropriate temperature, and the effect of the catalyst 51 can be maximized.

As described above, if the vaporization of the vaporized gas a is promoted at various places and the temperature of the catalyst 51 is appropriately set, the vaporized gas a can be deodorized extremely well and no odor is felt from the exhaust gas. Absent. In addition, if heating is performed by the first and second heaters 43 and 44 before the incineration of filth is started, the catalyst 51 effectively performs the deodorizing action from the start of the incineration and the odor is not felt. ..

6 and 7 show a storage case of the incinerator according to the above embodiment.

In this storage case, the two doors 6 with two doors open
1, the doors 61 are opened, the incinerator is placed on each crossbar 62 at the bottom of the case, and the incinerator is fixed by a plurality of stoppers 63.

The left side wall of this storage case has an exhaust hole 64.
The exhaust hole 64 and the discharge hole 12 of the incinerator are connected through an aluminum corrugated pipe 81 as shown in FIG. 8 so that the exhaust hole 64 is discharged from the discharge hole 12 of the incinerator. Guide the exhaust gas to the exhaust hole 64,
Exhaust from here.

A heat exhaust fan 65 is provided on the right side wall of the storage case, and the heat exhaust fan 65 is provided.
The hot air in the case is released to the outside.

Further, suspension hooks 66 are provided at the four corners of the upper side wall of the storage case, and a chain block 91 as shown in FIG. It is fixed by screwing 91a. One chain 92 of the chain block 91 is connected to the chain block clasp 14 of the incinerator. Here, when hoisting the storage case and the incinerator, the four hanging hooks 6 of the storage case
Connect a rope or chain to 6 and lift. When removing the ash generated in the pot 1 of the incinerator, the thumbscrews 23, 24 of the incinerator are removed, the chain block 91 is removed from the hole 67, and the other chain 93 is removed from the hole 67. The chain 2 is pulled out and the chain 93 is pulled up by an appropriate means.
To remove ash.

A control device 68 is installed on the right outer wall of the storage case. The control device 68 includes terminals of the heaters of the incineration treatment device and thermocouples 7a, 7b, 4 respectively.
5, 46 terminals are connected through respective lines (not shown). The control device 68 includes a microcomputer that executes a preset program,
The heaters 4, 43, 44 are caused to generate heat on the basis of the respective temperatures measured by the thermocouples 7a, 7b, 45, 46, whereby the incineration process described above is performed.

By the way, the controller 68 repeats the above-mentioned incineration process every time waste is stored in the pot 1 of the incinerator, but repeats the heating of the first set temperature by the heater 4 a predetermined number of times. Then, after this, heating at a second preset temperature higher than the first preset temperature is performed once. For example, 10
Nine of the incineration treatments are performed at the first set temperature (for example, 4
Repeat at 50 ° C, once for the second set temperature (eg 6
00 ° C). The process is shown in the graph of FIG.

By thus periodically performing the incineration process at a temperature higher than usual (second set temperature), the unburned residue in the pot 1 of the incinerator can be completely burned. If the incineration process is always performed at a high temperature, the filth can be completely burned at any time, but in this case, a large amount of energy is consumed, and the maintenance cost is high. Further, considering the durability of the main body of the apparatus, it is preferable to perform the treatment at a high temperature periodically. This incineration method is not limited to the apparatus of the embodiment and can be appropriately applied to other simple incinerators.

[0040]

As described above, according to the present invention, since the waste is stored right under the heater, the waste can be efficiently heated and incinerated.

Further, since the reflecting plate is provided on the upper side of the heater, the filth is heated more efficiently and incinerated.

Further, since the vaporized gas flow passage is formed on the upper side of the reflection plate, vaporization of the vaporized gas passing through this passage can be promoted.

Further, since the incineration process is performed at a temperature higher than usual from time to time, the unburned residue in the pot can be completely burned with energy saving.
