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, etc., the present applicant has invented a garbage disposal machine as shown in FIG. 5 as a method of burning liquid fuel such as kerosene with a burner.
[0003]
Referring to FIG. 5, an odor air combustion chamber 52, a deodorizing catalyst 53, an orthogonal heat exchanger 54, downstream of a burner 51 that generates combustion heat for heating and drying raw garbage put into the drying container 50, An exhaust cylinder 55 is arranged. The heat exchanger 54 has a configuration in which one path communicates with the deodorization catalyst 53 and the exhaust cylinder 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. It is a thing.
[0004]
According to this configuration, the odorous air discharged from the inside of the drying container 50 flows into the odorous air combustion chamber 52 through the odorous air duct 58 as the garbage is heated and dried. 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 not decomposed by heating is 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 from the exhaust cylinder 55 to the outside.
[0005]
The air in the drying container also flows into the heat exchanger 54 through the circulation duct 56. Since the 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 container 50 introduced into the heat exchanger 54 by the circulation duct 56 passes through the heat exchanger 54. While passing, it becomes high-temperature air, enters the drying container 50 again through the high-temperature air duct 57, and heats and drys garbage. In this way, in the drying container 50, the high temperature air diffuses inside, so that the garbage can be efficiently dried. Further, the odor component generated when the garbage is dried is decomposed by the odor air combustion chamber 52 and the deodorization catalyst 53. Therefore, a garbage dryer with less odor can be supplied.
[0006]
[Problems to be solved by the invention]
However, in the structure as described above, since there are many ducts for communicating the constituent parts, the apparatus is complicated and the manufacturing cost is very high. In addition, heat is constantly radiated to the outside of the device from heat exchangers and ducts where the temperature is higher than the outside air, so the temperature of the air circulating inside the device decreases, which reduces the drying efficiency. It was also a cause.
[0007]
The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a garbage disposal machine that has a simple apparatus configuration, is inexpensive to manufacture, and has little reduction in drying efficiency due to heat dissipation.
[0008]

DETAILED DESCRIPTION OF THE INVENTION
With such a configuration, the odor air combustion chamber, the deodorization catalyst and the box body surrounding the orthogonal heat exchange chamber are provided, and the air in the drying container is configured to circulate through the inside of the box body. Since the orthogonal heat exchanger is covered with this circulating air, heat radiation from the deodorizing catalyst and the orthogonal heat exchanger to the outside of the apparatus is also suppressed, and a decrease in drying efficiency is suppressed. Further, at least one surface of the box is dried. By sharing the outer wall of the container, all the heat radiation from the surface shared with the drying container of the box flows into the drying container, so that the drying efficiency is improved and the piping structure is simplified.
[0014]
In addition, since a partition plate for separating the odorous air discharged from the odorous air suction means and the air circulating in the drying container is provided in the box, the odorous air and the air circulating in the drying container are There is no mixing.
[0016]
【Example】
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 and 2, 1 is a drying container for drying garbage, 2 is a burner section for generating combustion heat necessary for drying the garbage, and 3 is an odor component discharged from the drying container 1. It is an odorous air combustion chamber that is thermally decomposed by the combustion flame of part 2. Reference numeral 4 denotes a deodorization catalyst that is activated by the combustion heat of the burner section 2 to oxidatively decompose odor components. An orthogonal heat exchanger 5 is disposed downstream of the deodorization catalyst 4. And 6 is a discharge part which discharges the garbage which dried and 7 is an exhaust pipe.
[0017]
8 is a box extending from the bottom of the odorous air combustion chamber 3 so as to surround the odorous air combustion chamber 3, the deodorizing catalyst 4 and the orthogonal heat exchanger 5, and is orthogonal to the odorous air combustion chamber 3 and the deodorizing catalyst 4. It is provided so that the space | gap used as the air passage may be formed around the heat exchanger 5. Further, the box 8 has a partition plate 9 between the internal odorous air combustion chamber 3 and the deodorizing catalyst 4.
[0018]
The drying container 1 has an opening lid 10 that can be opened and closed at the top, a high-temperature air outlet 11, a circulating air inlet 12, a odorous air outlet 13, and a new airflow inlet 14 for introducing air from the outside. Have. The high temperature air outlet 11 communicates with the orthogonal heat exchanger 5, and a circulation fan 15 is disposed outside the circulation air inlet 12, and the circulation air inlet 12 is connected to the circulation air inlet 12 via the circulation fan 15. The circulation duct 16 communicates with the box body 8. That is, the internal air circulation means 17 composed of the circulation air inlet 12, the circulation fan 15, the circulation duct 16, and the high temperature air outlet 11 communicates with the orthogonal heat exchanger 5 and the drying container 1 through the box body 8. Constitutes an air circulation path.
[0019]
Reference numeral 19 denotes an odorous air suction fan 18 that sucks odorous air from the drying container 1 and blows it to the odorous air combustion chamber 3, and an odorous air duct 20 that communicates the odorous air suction fan 18 and the odorous air combustion chamber 3. A suction means 21 is a fresh air introduction port communicating with the new air flow inlet 14. Further, a stirring means 22 for stirring the garbage is provided in the vicinity of the bottom of the drying container, and a stirring driving means 23 for driving the stirring means 22 is provided outside. In order to prevent the garbage from sticking to the inside of the drying container and the stirring means 22, a fluorine-based surface treatment is applied.
[0020]
Moreover, as shown in FIG. 3, one path | route of the orthogonal heat exchanger 5 is connected to the deodorizing catalyst 4 and the exhaust pipe 7 (shaded arrow). The other path communicates with the box body 8 and the drying container 1 and is configured to heat and heat the air (white arrow) circulating through the air circulation path described above by the combustion heat of the burner section 2. Therefore, the air flowing into the box 8 from the circulation duct 16 flows in the gaps provided between the deodorizing catalyst 4 and the orthogonal heat exchange chamber 5 and the box 8 as indicated by black arrows, and passes through the orthogonal heat exchanger 5. Into the drying container 1.
[0021]
As shown in FIG. 4, the burner unit 2 includes a combustion fan 24, a burner 25, and a carburetor 26 that jets fuel gas to the burner 25. The burner 24 has a secondary air ejection plate 28 provided with a number of secondary air holes 27 for ejecting secondary air. The secondary air ejection plates 28 face each other on both sides of the crater 29. The outer peripheral passage 30 is connected to the outer peripheral passage 30 and has a double structure, and the inside and the outside communicate with each other through the odorous air ejection holes 31 formed in the opposing wall surface.
[0022]
Next, the operation in the above configuration will be described. When the charging lid 10 is opened and the garbage is thrown in for operation, the carburetor 26 is preheated and combustion preparations are started. When preheating is completed, an oil feed pump (not shown) is started, kerosene flows into the vaporizer 26, and the vaporized gas that has been heated and vaporized is ejected to the burner 25. On the other hand, the combustion fan 24 starts to rotate at a low speed, and the primary air flows into the burner 25.
[0023]
Therefore, the premixed gas of vaporized gas and primary air is ejected from the crater 29, ignited by an ignition device (not shown), and combustion starts. Further, secondary air is forcibly supplied from the secondary air ejection plate 28 to the combustion flame and complete combustion occurs. And the combustion heat of this combustion exhaust gas heats the odor air combustion chamber 3, the deodorization catalyst 4, and the orthogonal heat exchanger 5, and then is exhausted to the outside from the exhaust cylinder 7.
[0024]
Further, the stirring means 22 is rotated by the stirring drive means 23 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 23 rotates in the forward and reverse directions so that the garbage is not displaced in the drying container.
[0025]
When the circulation fan 15 is started almost simultaneously with the start of combustion, the air in the drying container 1 flows into the circulation duct 16 from the circulation air inlet 12 and is sent to the box body 8, passing through the gap in the box body 8, It flows into the orthogonal heat exchanger 5. Then, while passing through the orthogonal heat exchanger 5, heat exchange with the combustion heat of the combustion exhaust gas becomes high-temperature air, enters the drying container 1 from the high-temperature air outlet 11, and is crushed and agitated so that the garbage with an enlarged surface area is obtained. It will dry efficiently.
[0026]
Here, since the deodorizing catalyst 4 and the orthogonal heat exchanger 5 are heated to high temperatures due to the combustion heat from the burner section 2, they radiate heat to the outside of the apparatus. However, since the deodorizing catalyst 4 and the orthogonal heat exchanger 5 are covered with relatively low-temperature circulating air when the air in the drying container 1 passes through the gap of the box 8 as described above, the deodorizing catalyst 4 and the orthogonal heat The heat released from the exchanger 5 is absorbed by this circulating air. Therefore, heat radiation to the outside of the apparatus is suppressed, and a decrease in drying efficiency is suppressed.
[0027]
Furthermore, since at least one surface of the box 8 is shared with the outer wall of the drying container 1, all heat released from the shared surface flows into the drying container 1 and is consumed as heat energy for drying the garbage. As a result, the drying efficiency is improved, and the duct for communicating the box 8 and the drying container 1 is not required, so that the piping structure is simplified.
[0028]
Further, since the odorous air suction fan 18 forcibly sucks the odorous air inside the drying container 1 through the odorous air discharge port 13, the inside of the drying container 1 becomes negative pressure and enters the new air flow inlet 14 of the drying container 1. External air is introduced from the fresh air inlet 21, and water vapor is taken away from the garbage, resulting in high-humidity odor air. Moreover, the odor component is also prevented from leaking outside from the seal portion of the drying container 1.
[0029]
Then, the odor component of the odor air blown into the odor air combustion chamber 3 through the odor air duct 20 by the suction of the odor air suction fan 18 is thermally decomposed by the combustion flame of the burner section 2. Further, the odor component remaining in the odor air combustion chamber 3 without being thermally decomposed flows into the deodorization catalyst 4 downstream of the odor air combustion chamber 3 and is completely oxidized and decomposed. At this time, the amount of odorous air sent to the odorous air combustion chamber 3 by the odorous air suction fan 18 is set to a minimum to suppress the temperature drop of the odorous air combustion chamber 3 and the deodorizing catalyst 4, so that the odorous air is efficiently used. Can be processed well.
[0030]
Moreover, since the space | gap formed between the box 8 and the deodorizing catalyst 4 and the orthogonal heat exchange chamber 5 is connected with the drying container 1 by the circulation duct 16, it is a negative pressure. On the other hand, in the burner unit 2 and the odorous air combustion chamber 3, the internal pressure becomes positive due to the rotation of the combustion fan 24 and the odorous air suction fan 18, and when such a pressure difference occurs, the air becomes negative from the positive pressure. It flows into the pressure. Therefore, the partition plate 9 is provided in the box 8, and the inside of the box 8 is divided to prevent the odorous air that has flowed into the odorous air combustion chamber 3 from flowing into the air circulating inside the apparatus by the internal air circulation means 17. The path for deodorizing and discharging the odorous air and the path for heating the drying container 1 by circulating inside the apparatus are prevented from being mixed.
[0031]
【The invention's effect】
As described above, the garbage processing machine of the present invention is provided with a box body that surrounds the odorous air combustion chamber, the deodorization catalyst, and the orthogonal heat exchange chamber, and the air flowing from the internal air circulation means passes through the gaps in the box body. Since the deodorizing catalyst and the orthogonal heat exchanger are covered with the circulating air, the heat release to the outside of the apparatus is suppressed, and the reduction in drying efficiency can be suppressed.
[0032]
In addition, all the heat radiation from the surface shared with the drying container of the box flows into the drying container and is consumed as thermal energy for drying the garbage. And the piping structure can be simplified.
[0033]
Further, in the invention of claim 2, since the inside of the box is divided by the partition plate, the path for deodorizing and discharging the odorous air and the path for circulating the inside of the apparatus and heating the drying container are mixed. Can be prevented.
