Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a waste processing device for incinerating and reducing the amount of waste such as kitchen waste.

BACKGROUND OF THE INVENTION Conventionally, as shown in FIG. 6, this type of garbage disposal apparatus has a box-shaped frame 1 having a lid 104 that can be opened and closed at the top.
A heat insulating material 102 is pasted on the inner surface of 01, and an exhaust port 109 communicating with the outside is provided on the side wall surface of the exhaust port 109.
On the downstream side of the catalyst 11 is heated by a catalyst heater 111.
A purifier 110 that purifies exhaust gas by enhancing the effect of No. 2 is connected.

A heater 103'jz is fixed to the inner bottom of the frame 101 so that its tip protrudes inward.
The terminal portion of the frame body 101 projects outward from the frame body 101. Inside the frame 101, a metal processing container 105 is placed on the heater 103. A cylindrical portion that encloses the heater 103 is formed at the bottom of the processing container 105, and an opening is provided in the wall of the cylindrical portion. Air supply port 1 allows air to flow into the processing chamber 19105 from this opening.
07 is provided on the bottom surface of the frame 101, and this air supply port 107
A blower 108 is provided.

Then, open the lid 104 and dump the garbage 106 into the processing container 106.
When the heater 103 is turned on after the lid 104 is closed, the thermal energy of the heater 103 will remove the waste 1.
06 is heated and incinerated.

The air necessary for combustion is supplied to the blower 10B through the air supply port 107.
The exhaust gas supplied and generated is mainly unburned hydrocarbon compounds, but it is decomposed into water and carbon dioxide gas by the purifier 110, purified, and discharged. The operation of the device is controlled by the set time of a program timer that is predetermined according to the amount of waste.5 As shown in Fig. 7, the catalytic heater 111 and the blower 108 are first operated, and then the purifier is turned on for the set time l. 110 into a sufficiently functional state, the heater 103 is operated, and after a set time ■', the heater 103 and the catalyst heating heater 111 are stopped to complete the incineration process, and then the device is cooled with air during the set time ■. The blower 108'i was to be stopped.

Problems to be Solved by the Invention In such a conventional configuration, the set time for incineration processing is arbitrarily set by the user, so it is set longer than the net required operating time for boat fishing. For no energy,
In addition to being wasted, there are problems in that depending on the composition of the waste, it takes time to process it, and the equipment may stop working without being processed. In addition, there are cases where temperature detection is used as a method for determining the completion of incineration processing.1 For example, there is a method of detecting the atmospheric temperature inside the furnace, but since there are large variations in the combustion state and progress of combustion, this is not a simple method. The problem was that the determination accuracy was poor and there was no effective method.

The present invention solves these problems.

It is an object of the present invention to provide an easy-to-use operating method for a garbage processing device that can be operated automatically in a simple manner and accurately according to the amount and quality of garbage.

Means for Solving the Problems In order to solve the above-mentioned problem FI'%, the present invention provides temperature detection means for detecting temperature changes in the processing volume 2g disposed within the frame body and in which waste is incinerated. The system is configured to determine whether incineration is complete based on changes in the temperature of the processing container.

Function: With this configuration, the end of incineration is detected based on temperature changes in the processing container, which is less susceptible to variations in combustion conditions, etc., so it can respond to changes in the quantity and quality of waste.

Furthermore, it is possible to easily and accurately determine the end of the incineration process.

EXAMPLE Hereinafter, an example of the present invention will be described based on FIGS. 1 to 5. In the figure, a frame 1 is made of a material with high heat resistance such as metal or ceramic, and its inner surface is lined with a heat insulating material 2 such as ceramic fiber which has high heat resistance and has a heat insulating effect. A heater 3 is provided at the inner bottom of the frame 1 to heat the dirt 6 that penetrates the heat insulating material 2 from the outside and protrudes into the frame 1. Furthermore, a lid 4 that can be opened and closed is provided on the top of the frame 1 to allow garbage 6 to be thrown in. A waste 6 processing container 6 is disposed above the heater 3 and has a cylindrical part with an opening in the wall surrounding the heater 3 at the bottom, and the waste 6 thrown in after opening the lid 4 is processed. It is stored in a container 6. Furthermore, a temperature detection means 6a such as a thermistor for detecting the temperature of the lower part of the processing container 5 is provided on the bottom surface of the frame 1 so as to penetrate through the frame 1. There are other things on the bottom of frame 1.

An air supply lower is provided to allow air to flow into the processing container 5, and a blower 8 provided in communication with the air supply lower sends the air necessary for combustion. It also communicates with an exhaust port 9 opened in a part of the side wall of the frame 1, and is heated by a heater 11. A purifier 1Q is provided to purify exhaust gas by enhancing the action of 1412, and the exhaust gas generated by combustion is purified and discharged to the outside. The temperature detection means 5a
and the start switch 13 are input to the control means 14. This control means 14 controls the heater 3, the blower 8°, the catalyst heating heater 11, and the start switch 13.
When the button is pressed, each part is brought into operation in sequence, and the amount of waste 6 in the frame 1 is reduced by incineration. Then, the temperature detecting means 5a detects a temperature change in the processing container 6 that occurs near the end of the arm removal, and based on this input number m, the control means 14 stops each part,
Terminate the process.

Next, a detailed explanation will be given based on FIGS. 2 and 3. Blower 8, heater 3. The contact 11X heater 11 is connected to an AC α source through switching means 15a to 150% f source switch 20i which are controlled on and off by a control means 14. This control means 14 receives input from the start switch 13 and controls the catalyst heating heater 11 and the blower 8.
Switching means 16a and 15c (5
Turn on. Then, the catalyst heater 11 produces a salmon taste 12.
is heated, the purifier 10 becomes active, and air is blown into the trunk body 1 by the blower 8. Then, the switching means 15bi is turned on to heat the heater 3 at a predetermined time of 1 m long enough for the purifier 1o to be activated. The throughput container 5 contains waste 6 which is thrown in after opening the lid 4 and is strongly heated by the thermal energy of the heater 3. And garbage 6
It dries, reduces its volume, and is eventually incinerated.

FIG. 4 is a graph showing changes in the atmospheric humidity in the frame 1 and the temperature in the upper, middle, and lower parts of the throughput container 6 from the time when the heater 3 is energized until the end of incineration. As shown by the thin line in the graph, the ambient temperature changes irregularly due to variations in the quality of the garbage and the combustion itself. However, the temperature of the processing container 6 is not easily affected by variations in combustion, changes stably, and always rises to a certain temperature range by the end of incineration, regardless of the amount of processing. On the other hand, the temperature of the processing container 5 exhibits a characteristic change pattern toward the lower part. The thick solid line in the graph indicates the temperature at the lower part of the processing container 5, which is maintained near the water evaporation temperature of 100° C. until just before the end of incineration, and then rapidly rises to the above-mentioned constant temperature range.

In addition, we investigated the time required from when the processing amount er6 reached a certain temperature to the incineration process.

It is known that the temperature will settle down within a certain amount of time depending on the set temperature level. Therefore, after determining that the temperature at the lower part of the processing container 5 has reached a predetermined set temperature based on a signal from the temperature detection means 5a after the heater 3 is energized, the control means 14 also sets a predetermined setting according to the set temperature. After time {circle over (2)}, switching means 16b and 15c are turned off to stop heater 3 and catalyst heating heater 11. After that, the blower 8 is operated for a predetermined set time (■), and after cooling the device with air, the switching means 16a
is turned off to stop the blower 8. Further, the control procedure of the control means 14 is as shown in FIG.
After reaching the set temperature, delay the set time, set time ■
Then stop the cold air operation.

In the above embodiment, the heater 3 and the catalyst heater 11 were stopped at the same time, but the catalyst heater 11 was operated even after the heater 3 was stopped to treat residual gas.
The operation may be controlled to be delayed.

Effects of the Invention As described above, according to the present invention, a temperature detection means is provided in the waste processing container, and the temperature change during the waste incineration process is detected to determine the completion of incineration. It is possible to realize an easy-to-use garbage treatment device that is capable of automatic operation and that does not waste power or leave untreated waste.
