【Example】
Embodiments of the present invention will be described below with reference to the drawings.
[0011]
(Example 1)
FIG. 1 shows a cross-sectional view of a waste disposal apparatus in a first embodiment of the present invention.
[0012]
In FIG. 1, reference numeral 20 denotes a waste treatment apparatus main body (hereinafter referred to as a main body). Reference numeral 21 denotes a waste processing container (hereinafter referred to as a processing container) for storing the waste A. Reference numeral 22 denotes a heating means including an electric heater which is detachably installed on the bottom wall of the processing vessel 21. Reference numeral 23 denotes a lid that detachably fits the upper opening of the processing container 21 so that the upper opening of the processing container 21 is substantially sealed with the waste A inside. An exhaust passage 24 communicates with the inner wall of the lid 23, and the other communicates with an oxidation catalyst portion 26 that houses an oxidation catalyst 25, and is connected to the outside air via the oxidation catalyst portion 26. A control unit 27 is connected to the heating unit 22 and controls energization. Reference numeral 28 denotes a temperature measuring means that is in pressure contact with the processing vessel 21 and is connected to the control means 27. Reference numeral 29 denotes a cooling air passage (space) provided around the processing vessel 21, and communicates the intake port 30 at the bottom of the main body and the exhaust port 31 provided around the upper lid 23.
[0013]
About the waste processing apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. When the lid 23 of the main body 20 is opened, the waste A is put in, the lid 23 is closed, and the operation is started, the control means 27 measures the temperature of the processing container 21 with the temperature measuring means 28 and makes a predetermined heating pattern. In addition, the energization control is performed on the heating means 22 to heat the processing container 21. Water vapor and dry distillation gas are generated from the waste A by heating, pass through the exhaust passage 24, undergo oxidation through the oxidation catalyst portion 26, and then released to the outside air. When the generation of the dry distillation gas is finished, the heating process is finished, and the control means 27 stops energizing the heating means 22. Since a cooling air passage 29 that communicates from the inlet 30 at the bottom of the main body 20 to the periphery of the lid 23 at the top of the main body 20 is disposed around the processing container 21, outside air naturally flows from the bottom to the top of the cooling air passage 29. Introduced and efficiently cooled the processing vessel 21 from the surroundings, the processing vessel can be cooled quickly and the outer shell of the main body can be prevented from being heated.
[0014]
As described above, according to the present embodiment, the cooling after the heat treatment is efficiently and smoothly performed, thereby achieving a faster process time and preventing the outer shell from being heated at a high temperature. It is possible to provide a good waste treatment apparatus.
[0015]
In the present embodiment, the temperature measuring means 28 is pressed against the processing container 21 and is provided to measure the temperature of the processing container 21, but may be attached to measure the atmospheric temperature inside the processing container 21. There is no problem.
[0016]
(Example 2)
FIG. 2 shows a configuration diagram of the waste disposal apparatus in the second embodiment of the present invention. In addition, the thing of the same code | symbol as Example 1 has the same structure, and detailed description is abbreviate | omitted.
[0017]
In FIG. 2, the difference from the configuration of the first embodiment is that a blower 32 is provided in the cooling air passage 29. The blower 32 is installed with the air outlet 33 facing the cooling air passage 29 and is connected to the control means 27.
[0018]
About the waste processing apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. When the waste treatment apparatus according to the second embodiment of the present invention is operated, outside air flows into the cooling air passage 29 from the lower side to the upper side, which contributes to shortening the cooling time after the heating process is completed. In the present embodiment, the cooling air passage 29 is further provided with a blower 32 so that even the narrow cooling air passage 29 can be efficiently and efficiently cooled in a short time, and the blower 32 is controlled. After the heating process is completed by connecting the means 27 and operating the blower 32 at the time of the temperature drop of the processing vessel 21 measured by the temperature measuring means 28 after the heating process using the heating means 22 is completed, More efficient cooling using the blower 32 is possible only when cooling.
[0019]
( Reference Example 1 )
FIG. 3 shows a configuration diagram of the waste disposal apparatus in the first reference example of the present invention. In addition, the thing of the same code | symbol as Example 1 has the same structure, and detailed description is abbreviate | omitted.
[0020]
In FIG. 3, the difference from the configuration of the first embodiment is that an air passage shut-off valve 34 for opening and closing the exhaust port 31 is provided at the exhaust port 31 of the cooling air passage 29, and a drive device 35 for driving the air passage shut-off valve 34 is controlled by the control means. This is a point connected to 27.
[0021]
About the waste processing apparatus comprised as mentioned above, the operation | movement and an effect | action are demonstrated below. The overall operation is the same as that of the waste disposal apparatus described in the first embodiment. In addition, by providing the air passage shutoff valve 34 at the exhaust port 31 of the cooling air passage 29, the cooling air passage 29 becomes a closed space when the air passage shutoff valve 34 is closed, and there is no air movement. When the air passage shut-off valve 34 is opened, the outside air flows through the cooling air passage 29 as described in the first embodiment, and the cooling effect can be exhibited. Insulation and cooling can be selectively operated by the air passage opening / closing valve 34, so that both the improvement of the insulation performance during heating and the improvement of the cooling performance during cooling can be achieved, enabling more efficient waste disposal, The processing time can be shortened and the usability can be improved.
[0022]
Further, by connecting and controlling the driving device 35 of the air passage shut-off valve 34 to the control means 27, the air passage shut-off valve 34 can be driven automatically at a predetermined time or in a predetermined process, so that it is easier to cool. Thus, the cooling performance can be improved, more efficient waste processing becomes possible, the processing time can be shortened, and the usability can be further improved.
[0023]
Further, since the air passage shut-off valve 34 is closed when the temperature of the processing container 21 measured by the temperature measuring means 28 reaches a predetermined temperature or more, the heat insulation performance during heating is improved, and more efficient waste treatment is performed. This makes it possible to shorten the processing time and further improve the usability.
[0024]
Subsequently, by opening the air passage shut-off valve 34 when the temperature of the processing container 21 measured by the temperature measuring means 28 is lowered, the cooling performance at the time of cooling is improved, and more efficient waste processing is possible. Thus, the processing time can be shortened and the usability can be further improved.
[0025]
In the present invention, an example in which the airway shut-off valve is opened / closed by the control means 27 has been described. The present invention is effective even when a driving source that directly receives the power and generates the driving force is used, and even if it does not necessarily depend on the control means, it does not depart from the spirit of the present invention.
[0026]
Further, the air passage shut-off valve 34 described in Reference Example 1 of the present invention is effective regardless of where it is disposed from the upstream to the downstream of the cooling air passage 29, and the effectiveness of the present invention depends on the installation position. Is not impaired and does not depart from the spirit of the present invention.
[0027]
