Description

[0001]
[Technical field to which the invention belongs]
The present invention relates to a garbage processing machine that measures the weight reduction by heating and drying the garbage from a factory, a restaurant, a hotel, a general household, and the like.
[0002]
[Prior art]
As a garbage processing machine that heats and drys garbage, a method of heating to high temperature with an electric heater or high temperature air obtained by burning liquid fuel such as gas or kerosene with a burner and exchanging heat with the combustion heat is used. Although there is a method of spraying and drying garbage, the present inventor has invented a garbage processing machine of the type shown in FIG. 8 that burns liquid fuel such as kerosene with a burner.
[0003]
Referring to FIG. 8, an odor air combustion chamber 52, a deodorizing catalyst 53, an orthogonal heat exchanger 54, an exhaust path are provided downstream of a burner 51 that generates combustion heat for heating and drying raw garbage put into the drying container 50. 55 is arranged. The orthogonal heat exchanger 54 is configured such that one path communicates with the deodorizing catalyst 53 and the exhaust path 55 and the other path communicates with a circulation duct 56 and a high-temperature air duct 57 that circulate the air in the drying container 50. It is what. That is, an internal air circulation path 58 including the drying container 50, the circulation duct 56, the orthogonal heat exchanger 54, and the high temperature air duct 57 is formed. Reference numeral 59 denotes odor air suction means for introducing odor air from the inside of the drying container 50 into the odor air combustion chamber 52.
[0004]
According to this configuration, the odorous air sucked from the inside of the drying container 50 by the odorous air suction means 59 flows into the odorous air combustion chamber 52 along with the heat drying process of the garbage. The odor component of the odor air is thermally decomposed in the odor air combustion chamber 52 by the combustion flame of the burner 51, and the odor component that is not thermally decomposed is also oxidized by the deodorization catalyst 53 activated by the combustion heat of the burner 51. As a result of being decomposed and having almost no odor component, the air is discharged to the outside from the exhaust passage 55.
[0005]
The air in the drying container 50 also flows into the orthogonal heat exchanger 54 through the circulation duct 56. Since the orthogonal heat exchanger 54 disposed downstream of the deodorizing catalyst 53 is also heated by the combustion heat of the burner 51, the air in the drying vessel 50 introduced into the orthogonal heat exchanger 54 by the circulation duct 56 is orthogonally heat exchanged. While passing through the vessel 54, it becomes hot air, enters the drying container 50 again via the high-temperature air duct 57, and heats and drys the garbage. As described above, in the drying container 50, the high temperature air diffuses through the internal air circulation path 58, so that the garbage can be efficiently dried. Further, the odor component generated when the garbage is dried also has the odor air combustion chamber 52 and the deodorization. Since it is decomposed by the catalyst 53, a garbage dryer with less odor can be supplied.

[Problems to be solved by the invention]
However, in the conventional garbage processing machine, it is necessary to increase the amount of air circulated by the internal air circulation path as much as possible in order to efficiently dry the garbage, and to maintain the activation of the deodorization catalyst. In order to keep the temperature of the deodorizing catalyst at a high temperature, it is necessary to minimize the amount of air from the drying container sucked by the odorous air sucking means. Therefore, the internal pressure of the internal air circulation path is larger than the internal pressure of the exhaust path.
[0008]
In such a structure in which the internal pressure of the internal air circulation path and the exhaust path is different, for example, there are fine holes in the orthogonal heat exchanger, or due to variations in packing etc. when assembling the orthogonal heat exchanger in the garbage treatment machine When the sealing performance is poor, the air in the internal air circulation path may leak into the exhaust path with a small internal pressure when passing through the orthogonal heat exchanger. Therefore, the air that passes through the exhaust path is air that has not been brominated by passing through the deodorizing catalyst, but this air contains air that contains odor components that have not been deodorized, and is used depending on the odor components that are mixed in. There was a problem of adversely affecting the people and the surrounding environment.
[0009]
This invention is for solving the said subject, and it aims at providing the garbage processing machine which can prevent a odor component from leaking out from a garbage processing machine while being able to dry garbage efficiently.

[0015]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
[0016]
1 is an external perspective view of a garbage disposal machine, FIG. 2 is a side configuration diagram, and FIG. 3 is a front configuration diagram. First, as shown in FIG. 1, reference numeral 1 denotes a main body of the garbage processing machine, and 2 denotes an openable / closable door for putting the garbage into the main body 1. Reference numeral 3 denotes an operation unit for controlling the operation of the garbage processing machine, and a processed product container for storing a container for receiving a dried processed product in the main body 1 below the operation unit 3. A storage unit 4 is provided.
[0017]
Next, from FIG. 2, 5 is a drying container stored in the main body 1 for drying the garbage, 6 is a burner section for generating combustion heat necessary for drying the garbage, and 7 is discharged from the drying container 5. This is an odor air combustion chamber in which the odor component to be heated is decomposed by the combustion flame of the burner section 6. Reference numeral 8 denotes a deodorization catalyst that is activated by the combustion heat of the burner section 6 to oxidatively decompose odor components. An orthogonal heat exchanger 9 is disposed downstream of the deodorization catalyst 8, and an exhaust path having an exhaust cylinder 10 downstream thereof. 11 communicates.
[0018]
Further, as shown in FIG. 3, a stirring means 12 for stirring the garbage is provided in the vicinity of the bottom of the drying container 5, and a stirring driving means 13 for driving the stirring means 12 is provided outside. Reference numeral 14 denotes a discharge port for discharging the garbage processed waste, and reference numeral 15 denotes a processed product container for storing the dried processed product from the discharge port 14. Reference numeral 16 denotes a discharge port opening / closing means for opening and closing the discharge port 14, and the discharge port 14 is opened and closed by a motor.
[0019]
Further, in the upper part of the drying container 5, an odor air suction port 18, which is provided with an odor air suction fan 17 as an odor air suction means for sucking odor air from the drying container 5 and sending it to the odor air combustion chamber 7. The odorous air inlet 18 and the odorous air combustion chamber 7 communicate with each other via an odorous air duct 19. That is, the odorous air from the drying container 5 is thermally decomposed in the odorous air combustion chamber 7 and then completely deodorized through the deodorizing catalyst 8, passes through the orthogonal heat exchanger 9, and has the exhaust cylinder 10. It is set as the structure discharged | emitted outside from the path | route 11 as odorless air.
[0020]
Here, FIG. 4 shows the exhaust path 11 communicating with the orthogonal heat exchanger 9, but a constricted portion 20 is provided in the cross section of the cylindrical exhaust tube 10, and the exhaust tube is connected to the orthogonal heat exchanger 9. The opening area through which the odorless air discharged to 10 passes is reduced. Although the throttle section 20 of the present embodiment adopts a shape in which the cross-sectional area of the exhaust cylinder 10 is reduced, the point is to reduce the opening area in order to increase the internal pressure of the exhaust path. The shape is not limited to the example.
[0021]
Further, as shown in FIG. 3, a circulation fan 22 as an internal air circulation means is disposed outside the circulation air suction port 21, and the circulation air suction port 21 and the circulation duct 23 are communicated with each other via the circulation fan 22. The duct 23 communicates with a box body 24 provided so as to form a gap serving as an air passage around the deodorizing catalyst 8 and the orthogonal heat exchanger 9. Reference numeral 25 denotes a hot air outlet duct for introducing high-temperature air that has passed through the orthogonal heat exchanger 9 into the drying container 5. That is, an internal air circulation path 26 having a circulation air inlet 21, a circulation fan 22, a circulation duct 23, a box body 24, an orthogonal heat exchanger 9, and a hot air outlet duct 25 communicating with the drying container 5 is configured.
[0022]
As shown in FIG. 5, the burner unit 6 includes a combustion fan 27, a burner 28, and a carburetor 29 that ejects fuel vaporized gas to the burner 28. Further, downstream of the burner 28, a secondary air ejection plate 31 having a number of secondary air holes 30 for ejecting secondary air is erected on both sides of the crater 32, and the odorous air combustion chamber 7 has an odor. A double structure having an outer peripheral passage that communicates with the air duct 19 is formed, and the inside and outside communicate with each other through a scented air ejection hole 33 formed in a large number on the opposing wall surface.
[0023]
Next, the operation in the above configuration will be described. When the door 2 of the main body 1 is opened and the garbage is put into the drying container 5 and the operation part 3 is operated, the combustion preparation such as preheating the vaporizer 29 is started. When preheating is completed, an oil feed pump (not shown) is started, kerosene flows into the vaporizer 29, and the vaporized gas heated and vaporized is ejected to the burner 28. On the other hand, the combustion fan 27 is also started at a low speed, and the primary air flows into the burner 28.
[0024]
Therefore, the premixed gas of vaporized gas and primary air is ejected from the crater 32, ignited by an ignition device (not shown), and combustion starts. Further, secondary air is forcibly supplied from the secondary air ejection plate 31 to the combustion flame and complete combustion occurs. And the combustion heat of this combustion exhaust gas heats the odor air combustion chamber 7, the deodorization catalyst 8, and the orthogonal heat exchanger 9, and then is exhausted to the outside through an exhaust path 11 having an exhaust cylinder 10.
[0025]
Also, the stirring means 12 is rotated by the stirring driving means 13 before and after the start of combustion, and the garbage is crushed and stirred to increase the surface area, thereby increasing the drying efficiency. Further, at the time of agitation / pulverization, the agitation drive means 13 rotates in the forward and reverse directions so that the garbage is not displaced in the drying container 5.
[0026]
Further, when the circulation fan 22 is started almost simultaneously with the start of combustion, the air in the drying container 5 flows into the circulation duct 23 from the circulation air suction port 21 and is sent to the box body 24, and as shown by the arrow in FIG. It flows into the orthogonal heat exchanger 9 through the air gap in the body 24. Then, the air passing through the orthogonal heat exchanger 9 exchanges heat with the combustion heat of the burner 28 to become high-temperature air, flows into the drying container 5 from the hot air outlet duct 25, and is crushed and stirred to increase the surface area of garbage. Will be dried efficiently.
[0027]
On the other hand, since the odorous air inside the drying container 5 is ejected from the odorous air suction port 17 through the odorous air duct 19 to the odorous air combustion chamber 7 by the odorous air suction fan 17. Further, the odor component that has been thermally decomposed by the combustion flame and remained without being thermally decomposed in the odor air combustion chamber 7 flows into the deodorization catalyst 8 downstream of the odor air combustion chamber 7 and is completely oxidized and decomposed.
[0028]
Here, the air circulated through the internal air circulation path 26 communicating with the drying container 5 is odorous air containing a lot of odor components generated from garbage in the drying container 5, but passes through the exhaust path 11. The air to be processed is odorless because it is completely deodorized by the odorous air combustion chamber 7 and the deodorizing catalyst 8. When the odorous air and odorless air pass through each path of the orthogonal heat exchanger 9 as shown in FIG. 7, if the internal pressure of the exhaust path 11 is smaller than the internal pressure of the internal air circulation path 26, for example, the orthogonal heat exchanger 9. If the orthogonal heat exchanger 9 has poor sealing performance, the odorous air in the internal air circulation path 26 leaks into the exhaust path 11 having a low internal pressure.
[0029]
However, as shown in FIG. 4, the exhaust passage 11 is provided with a constricted portion 20 so that the internal pressure of the exhaust passage 11 is larger than the internal pressure of the internal air circulation passage 26, so that there are fine holes in the orthogonal heat exchanger 9. Even if there is a bad sealing performance, odorous air does not leak into the exhaust path 11, and only odorless air leaks from the exhaust path 11 to the internal air circulation path 26. Therefore, the odor component does not leak to the outside of the main body 1 of the garbage disposal machine via the exhaust path 11, and it is possible to prevent the odor component from adversely affecting the user and the surrounding environment.
[0030]
As the garbage is dried as described above and the moisture in the drying container 5 is reduced, the temperature gradually rises from the upper part of the drying container 5. Then, when the temperature sensor provided in the drying container 5 detects a predetermined temperature, it is determined that the drying of the garbage has been completed, the combustion thermal power of the burner 28 is lowered, and after operating for a predetermined time, the burner 28 is extinguished. Thereafter, the circulation fan 22, the odorous air suction fan 17 and the stirring means 12 are operated for a predetermined time to cool the drying container 5 and the dried product, thereby completing the drying process of the garbage.
[0031]
When the drying process is completed, the motor of the discharge port opening / closing means 16 is actuated to open the discharge port 14 provided in the drying container 5, and the stirring means 12 is rotated in a fixed direction by the stirring drive means 13 to dry the garbage. The material is discharged from the discharge port 14 to the processed material container 15.
[0032]
【The invention's effect】
As described above, according to the first and second aspects of the present invention, the odor air in the drying container is sucked by the odor air suction means, and the deodorization treatment is performed by the odor air combustion chamber and the deodorization catalyst. After that, the internal pressure of the exhaust passage that passes through the orthogonal heat exchanger and is discharged to the outside is circulated while the constriction is provided in the exhaust passage and the air in the drying container is circulated while being heated and heated by the orthogonal heat exchanger. By making it larger than the internal pressure of the circulation path, it is possible to prevent the air in the internal air circulation path containing odor components from leaking into the exhaust path when passing through the orthogonal heat exchanger. It can prevent adverse effects.
