  In the above-mentioned garbage processing machine, when the garbage that has been dried in the drying container is turned into dust, these dusted dust and the like are exhausted by an exhaust filter provided at the exhaust outlet when discharged to the outside from the exhaust outlet. Generally, it is trapped, but when the hot air fan stirs and circulates the air in the drying container, dust particles are attracted to the hot air fan. Dust that has been pulverized will accumulate in the vicinity of.

  Then, since the electric heater for heating the air introduced from the outside is provided in the vicinity of the hot air fan, the dust accumulated in the vicinity of the hot air fan is heated by the electric heater. Therefore, there is a problem that dust or the like accumulated in the vicinity of the hot air fan is heated by the electric heater and ignites and burns.

  In addition, as with an exhaust filter at the exhaust port, providing a filter to cover the hot air fan and electric heater prevents dust from accumulating near the hot air fan and reduces the risk of ignition and combustion. However, since two filters are required, and maintenance must be performed with each filter attached and detached separately, there is a problem that the maintainability deteriorates.

  An object of the present invention is to solve the above-described problems, and an object of the present invention is to provide a garbage disposal machine that eliminates the risk of ignition and combustion of dust and the like in a drying container and has excellent filter maintainability.

  The present invention includes an open / close door that opens and closes to throw in garbage, a drying container that dries the garbage, a stirring means that stirs the garbage in the drying container, and a heating means that heats and drys the garbage, In the garbage processing machine having a circulation path for circulating the air in the drying container and an exhaust path for exhausting the air in the drying container to the outside, the circulation suction port of the circulation path and the exhaust suction port of the exhaust path It is related with the garbage processing machine characterized by covering with a single filter.

  2. The garbage processing machine according to claim 1, wherein the filter is attached and detached by opening and closing the door.

  2. The garbage disposal according to claim 1, wherein a reticulated filter is provided on the upstream side of the filter.

  With the above configuration, dust and the like do not enter the circulation path for circulating the air in the drying container, and the filter covering the circulation suction port and the exhaust suction port by opening the open / close door can be easily attached and detached. Can prevent the ignition and combustion of dust, etc., and improve maintainability. Furthermore, since the fibrous dust does not easily enter the filter, the filter can be prevented from being clogged at an early stage, and the maintainability can be greatly improved.

  The preferred embodiment of the present invention will be briefly described by showing the operation of the present invention.

  The present invention relates to a garbage disposal machine having a circulation path for heat-drying garbage to circulate the air in the drying container and an exhaust path for exhausting the air inside the drying container to the outside. And the exhaust inlet of the exhaust path is covered with a single filter. The filter can be attached and detached by opening the door. Further, a mesh filter is provided on the upstream side of the filter.

  That is, since one filter covers the circulation suction port and the exhaust suction port, dust generated in the drying container is captured by the filter and does not enter the circulation path and the exhaust path. In particular, since dust or the like no longer accumulates in the heating section that generates hot air in the circulation path, there is no danger of the dust or the like igniting or burning in the heating section. Further, when maintaining the filter, it is possible to easily remove the filter from the inside of the drying container by opening the door and attaching / detaching the filter, so that the maintenance performance can be improved.

  Further, since the mesh filter is provided on the upstream side (drying vessel side) of the filter, the fibrous dust is caught by the mesh filter and is hardly trapped inside the filter. Therefore, the filter can be prevented from being clogged early, and the filter can be cleaned in a short time, so that the maintainability can be greatly improved.

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 provided downstream of the deodorization catalyst 8, and an exhaust pipe 10 is communicated downstream thereof.

  An exhaust suction port 12 and an exhaust duct 13 communicate with an upper portion in the drying container 5 via an exhaust fan 11, and the exhaust duct 13 communicates with the odorous air combustion chamber 7. The air from the drying container 5 is thermally decomposed in the odor air combustion chamber 7, then completely deodorized through the deodorizing catalyst 8, passed through the orthogonal heat exchanger 9, and odorless from the exhaust tube 10. It is discharged outside as air. That is, the inside of the drying container 5 is passed through the exhaust path 14 including the drying container 5, the exhaust inlet 12, the exhaust fan 11, the exhaust duct 13, the odorous air combustion chamber 7, the deodorization catalyst 8, the orthogonal heat exchanger 9, and the exhaust cylinder 10. The air is exhausted to the outside.

  Further, the circulation suction port 15 and the circulation duct 17 communicate with each other via a circulation fan 16 disposed in the vicinity of the circulation suction port 15, and the circulation duct 17 is an air passage around the deodorizing catalyst 8 and the orthogonal heat exchanger 9. Are communicated with a box 18 that forms a gap and a hot air outlet duct 19 for introducing high-temperature air into the drying container 5. That is, as a structure in which the air in the drying container 5 is circulated by the circulation path 20 configured by the circulation inlet 15, the circulation fan 16, the circulation duct 17, the box 18, the orthogonal heat exchanger 9, and the hot air outlet duct 19. Yes.

  The stirring means 21 provided in the bottom of the drying container 5 has a structure in which a stirring arm 25 having a stirring blade 24 is attached to a rotating shaft 23 that is rotatable by a stirring motor 22. Reference numeral 26 denotes a discharge port for discharging the dry processed product of garbage, 27 denotes a dry processed product container for storing the dry processed product from the discharge port 26, and 28 denotes a discharge port opening / closing means for opening and closing the discharge port 26 by a motor. It is.

  In addition, a filter assembly 29 is provided in the upper part of the drying container 5 so as to cover the exhaust suction port 12 and the circulation suction port 15, and this filter assembly 29 has a structure in which the opening / closing door 2 can be opened and closed and pulled out to the front side. . That is, dust or the like generated during the drying process in the drying container 5 is captured by the filter assembly 29 provided on the upper part of the drying container 5 before being sucked into the exhaust suction port 12 and the circulation suction port 15. is there.

  4 and 5 are an oblique view and a cross-sectional configuration diagram showing details of the filter assembly 29. The filter assembly 29 includes a filter 29a, a metal net (mesh filter) 29b, a filter frame 29c, and a handle 29d. A metal net 29b is stacked on the upstream side of the filter 29a (inside the drying container 5) and fixed by a filter frame 29c, and a handle 29d is provided on the filter frame 29c. This handle 29d is used when the door 2 is opened and the filter assembly 29 is pulled out to the front side.

  The metal net 29b captures fibrous dust generated in the drying container 5. In other words, since it takes time to remove the fibrous dust when it enters the filter 29a, the metal net (network filter) 29b is provided so that the fibrous dust does not enter the filter 29a. In this embodiment, the filter assembly 29 is attached to the upper part of the drying container 5, but only the filter 29a may be attached. Furthermore, although the metal net 29b is used as the net filter, a resin net having heat resistance may be used, and the present invention is not limited to this embodiment.

  Next, the operation in the above configuration will be described. When the open / close door 2 of the main body 1 is opened, garbage is put into the drying container 5 and the operation start operation is performed by the operation unit 3, the burner unit 6 starts preparation for combustion such as preheating. When the preparation for combustion is completed, the burner unit 6 ignites the vaporized gas of kerosene and the premixed gas of primary air by an ignition device (not shown) and starts combustion. The combustion heat of the combustion exhaust gas generated by this combustion heats the odor air combustion chamber 7, the deodorization catalyst 8, and the orthogonal heat exchanger 9, and then is exhausted to the outside from the exhaust cylinder 10.

  Also, before and after the start of combustion, the stirring means 21 is rotated by the stirring motor 22 so as to repeat stirring and stopping, for example, stirring for 15 seconds / stopping for 15 seconds. This is to prevent the garbage from being caught in the stirring blade 24 and the inner surface of the drying container 5 at the same time.

  Further, when the circulation fan 16 is started at the same time as the stirring means 21 is driven, the air in the drying container 5 flows into the circulation duct 17 from the circulation suction port 15 and is sent to the box 18 and passes through the gap in the box 18. It flows into the orthogonal heat exchanger 9. The air passing through the orthogonal heat exchanger 9 exchanges heat with the combustion heat of the burner section 6 to become high-temperature air, flows into the drying container 5 from the hot air outlet duct 19, and is pulverized and stirred by the stirring means 21. Garbage with an enlarged surface area can be efficiently dried.

  On the other hand, since water vapor and odorous air generated in the drying container 5 by the drying operation is ejected from the exhaust inlet 11 through the exhaust duct 13 to the odorous air combustion chamber 7 by the exhaust fan 11, the odor component of the odorous air is The odor components which are thermally decomposed by the combustion flame of the burner section 6 and remain without being thermally decomposed in the odorous air combustion chamber 7 flow into the deodorizing catalyst 8 downstream of the odorous air combustion chamber 7 and are completely oxidized and decomposed to be exhaust cylinder 10. To the outside as odorless air.

  Here, in the drying container 5, the garbage is heated and dried by the high-temperature air generated in the circulation path 20, so that water vapor, odorous air, dust and the like are generated. The dust and the like are captured by the filter assembly 29 provided at the upper portion of the drying container 5 before being sucked into the circulation suction port 15 and the exhaust suction port 12 by the circulation fan 16 and the exhaust fan 11. That is, it is possible to prevent dust and the like from entering the circulation path 20 and the exhaust path 14 with one filter assembly 29.

  That is, clogging of the deodorizing catalyst 8 is less likely to occur in the exhaust path 14, and clogging is less likely to occur in the orthogonal heat exchanger 9 that generates high-temperature air in the circulation path 20. Therefore, there is no risk that dust or the like enters the circulation path 20 and the orthogonal heat exchanger 9 is clogged, and the dust or the like is heated to ignite and burn.

  When maintaining the filter assembly 29, the opening and closing door 2 is opened, the handle 29d of the filter assembly 29 is held, and the filter assembly 29 can be easily taken out from the inside of the drying container 5 to improve the maintainability. It can be done. In this embodiment, the filter assembly 29 is provided on the upper part of the drying container 5, but it may be provided on the side surface, and is not limited to this embodiment. In short, the circulation inlet 15 and the exhaust inlet 12 may be covered with a single filter assembly 29, and the filter assembly 29 may be attached and detached by opening the door 2.

  Furthermore, since the fibrous dust generated in the drying container 5 is caught by the metal net 29b provided on the upstream side of the filter 29a and captured, it does not enter the filter 29a. That is, when fibrous dust enters the filter 29a, it takes time to remove it. However, by providing the metal net 29b, almost no fibrous dust enters the filter 29a, so that the filter 29a can be cleaned easily. It can be done in time, and maintenance can be greatly improved.
