[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an organic substance processing apparatus that processes organic substances such as garbage.
[0002]
[Prior art]
Today, in households and convenience stores where organic matter such as garbage is discharged, organic matter processing apparatuses are often used for the purpose of self-treatment of the organic matter.
[0003]
For example, as shown in FIG. 25, the organic matter processing apparatus has a treatment tank 200 in which a carrier of microorganisms is placed. The organic matter is put into the tank 200 and stirred by a stirring body 201 to decompose organic matter by the microorganisms. It is.
[0004]
At this time, in order to activate the microorganisms and promote the decomposition process of the organic matter, the treatment tank 200 is kept at 60 ° C., for example.
[0005]
It should be noted that malodorous gas is generated during the decomposition process of the organic matter, and if it is exhausted as it is, it is deodorized and exhausted to cause environmental pollution.
[0006]
It should be noted that malodorous gas is generated during the decomposition process of the organic matter, and if it is exhausted as it is, it is deodorized and exhausted to give the user a feeling of discomfort.
[0007]
Therefore, the exhaust gas is heated to about 250 ° C. to 300 ° C. by the heater 202 and brought into contact with the catalyst 203 to perform oxidative decomposition.
[0008]
As described above, the exhausted gas is heated to increase the deodorization efficiency, and most of the heat is released to the outside air. On the other hand, the treatment tank 200 needs to be heated in order to promote the decomposition treatment of organic matter.
[0009]
For this reason, the sucked outside air is preheated by exchanging heat with the heater 202 or the like and supplied into the processing tank 200, and the heated exhausted gas from the catalyst 203 is guided to the bottom 204 of the processing tank 200. Thus, the temperature of the processing tank 200 and its contents is increased.
[0010]
Of course, it is also possible to provide a separate heater so that the outside air taken in can be directly preheated and supplied to the treatment tank 200 as it is.
[0011]
[Problems to be solved by the invention]
However, in the configuration in which the outside air is preheated by the heater 202 that heats the exhaust gas supplied to the catalyst 203, a large power is required for the heater 202, and there is a problem that the heater 202 becomes large. In the configuration in which the preheating heater is provided, there is a problem that the member cost is increased accordingly.
[0012]
In addition, in the organic matter processing apparatus so far, the heat generated by the motor that drives the stirrer, the fan that sucks in the outside air and exhausts the gas, and the control unit that drives and controls them is discarded without being used. Since it is heated, there is a problem that the utilization efficiency of heat is low.
[0013]
Then, an object of this invention is to provide the organic substance processing apparatus which raised this heat utilization efficiency.
[0014]
[Means for Solving the Problems]

[0019]
This organic matter processing apparatus is used for business use in, for example, a convenience store. For example, the organic substance introduced into the treatment tank 9 is decomposed while being stirred by the stirrer 10, and the stirrer 10 is powered. A ventilation unit 4 that circulates outside air to the drive unit 3 and the treatment tank 9 and exhausts the gas generated in the treatment tank 9 to the outside of the apparatus, a deodorization part 5 that deodorizes the gas exhausted to the outside of the apparatus, and an organic matter is decomposed The main components are a discharge unit 6 for taking out the processed product out of the apparatus, a loading unit 7 for feeding organic matter into the treatment tank 9, an alarm means (not shown) for monitoring the state of the apparatus, and the like. 8 is housed.
[0020]
The processing unit 2 stores a microbial carrier (usually wood chips such as sawdust) in advance, and a processing tank 9 into which an organic substance to be decomposed is charged, a processing tank 11 having a large capacity from the processing tank 11. It has the partition plate 14 divided into the discharge chamber 12 with a small capacity, the stirring body 10 for stirring the organic matter in the treatment tank 9, and the like.
[0021]
FIG. 5 is a perspective view showing the configuration of the frame 13 that houses the processing tank 9, and FIG. 6 is a diagram showing the configuration of the processing tank 9.
[0022]
The processing tank 9 is partitioned by a partition plate 14 and is divided into a processing chamber 11 and a discharge chamber 12. However, an organic substance such as garbage is put into the processing chamber 11 for decomposition treatment, and the processing is performed. The processed material which has been decomposed in the chamber 11 and turned into powder is transferred to the discharge chamber 12 by the movement of the stirring member 10 and is waiting to be discharged out of the apparatus in the discharge chamber 12.
[0023]
Transfer of the processed material from the processing chamber 11 to the discharge chamber 12 is performed via a transfer port 15 provided at the upper end of the partition plate 14, and a transfer door 16 is provided on the discharge chamber 12 side of the transfer port 15. It has been.
[0024]
The transfer door 16 is formed to be appropriately larger than the transfer port 15, and its upper end is rotatably attached to the partition plate 14 so that the processed material in the discharge chamber 12 is not transferred back to the process chamber 11. .
[0025]
The processing tank 9 has a substantially U-shaped side cross section, and has a bottom having a double bottom structure. A plurality of air dividers 18 are arranged in the double bottom space 17.
[0026]
And the exhaust gas heated by the deodorizing part 5 passes through this double bottom space 17, and is exhausted outside the apparatus, and the treatment tank 9 is heated by the exhaust gas at that time.
[0027]
At this time, if the exhaust gas blows to a part of the processing tank 9 and the processing tank 9 has a large temperature distribution, the processed material may burn, particularly when the stirring is stopped, Microorganisms may die.
[0028]
Therefore, the air divider 18 is provided in the double bottom space 17. The air distribution plate 18 is a plate material disposed so as to block the exhaust gas, and when the exhaust gas hits the air distribution plate 18, the exhaust gas is dispersed to the left and right to be spread over the entire double bottom space 17. It is designed to cross the line.
[0029]
In addition, although the exhaust gas is dispersed throughout the double-bottomed space 17 by the air diverting plate 18, the applied heat is diffused and spreads quickly, so that the temperature distribution in the treatment tank 9 is reduced. As shown in FIG. 2, a heat equalizing member 20 is provided on the bottom surface 19 of the treatment tank 9 at the double bottom.
[0030]
The soaking member 20 is made of a material having high thermal conductivity (for example, aluminum, copper, nickel, zinc, etc.) and is attached to the bottom surface 19 of the treatment tank 9 by adhesion or plating.
[0031]
In addition, if it arrange | positions so that the soaking | uniform-heating member 20 may be pressed against the processing tank 9 by the air-dividing plate 18, it is effective in the peeling suppression of the said soaking | uniform-heating member 20 and improving the adhesiveness of the soaking | uniform-heating member 20 and the processing tank 9. Is.
[0032]
Moreover, since the raw garbage just thrown into the processing tank 9 contains a lot of moisture, it adheres to the inner wall of the processing tank 9, and even if the stirring body 10 is driven, a part of the raw garbage may stagnate. is there.
[0033]
In general, when a new garbage is introduced, the treatment tank 9 contains a decomposed treatment product in addition to the above-described microorganism carrier. Therefore, these are mixed in the input garbage.
[0034]
For this reason, if the stagnation of garbage occurs as described above, the stagnation garbage is always heated even if the temperature distribution of the treatment tank 9 is not large or the temperature is low. As a result, the temperature may rise and burn or microorganisms may die.
[0035]
In order to prevent such a state, it is preferable to coat the inner wall of the treatment tank 9 with a stagnation prevention member 21 that has heat resistance such as fluororesin and that is slippery.
[0036]
The agitator 10 includes a rotation shaft 22 that is rotatably supported, and a large number of stirring rods 23 that are shifted in phase with respect to the rotation shaft 22, and is supported by a bearing member that will be described later. .

[0041]
Further, the side plates 28a, 28b of the processing tank 9 are provided with through holes 35 that are appropriately larger in diameter than the rotation shaft 22 and through which the rotation shaft 22 is inserted, and screws that secure the seal fixing plate 34 with screws. A hole 36 is provided.
[0042]
Further, the side plates 28a and 28b of the processing tank 9 are formed with insertion holes 37 through which screws 112 for engaging the bearing unit 31 and the bearing support fitting 32 are inserted. The insertion hole 37 is formed to be appropriately larger than the diameter of the screw 112, and the alignment of the bearing member 30 can be adjusted as will be described later.
[0043]
When the agitator 10 is attached, the left and right bearing units 31 and the bearing support fittings 32 are aligned with the positions of the through holes 35 and temporarily fixed, and the rotating shaft 22 is inserted. Thereafter, the sprocket 25 is fixed and the position of the rotary shaft 22 is adjusted.
[0044]
It is also possible to perform welding 113 on at least one of the bearing unit 31 or the bearing support fitting 32 to the side plates 28a and 28b after adjusting the position of the rotating shaft 22.
[0045]
As described above, the bearing support fitting 32, the seal fixing plate 34, and the like are provided so as to jump out into the processing tank 9, so that the following effects that cannot be obtained conventionally can be achieved. FIG. 10 shows a conventional configuration corresponding to FIG.

By providing the bearing support bracket 32 and the like so as to protrude into the processing tank 9, it becomes possible to enlarge the processing tank 9 by this protruding amount without increasing the external dimensions of the organic matter processing apparatus, and to improve the processing capacity. Increase is possible.
[0047]
Further, since the bearing support fitting 32 and the like are provided so as to protrude into the processing tank 9, the distance between the sprocket 25 and the side plate 28a corresponding thereto is shortened, and the moment applied to the rotating shaft 22 is reduced. Therefore, since the force for holding the bearing unit 31 is small, the thickness of the side plates 28a and 28b in the processing tank 9 can be reduced.
[0048]
Further, even if the bearing support metal fitting 32 is not welded and fixed to the side plates 28a and 28b as in the prior art, the side plates 28a and 28b are simply sandwiched between the bearing unit 31 and the bearing support metal fitting 32 and screwed. Since the position can be maintained, there is no displacement in the rotation shaft 22 caused by the misalignment of the welding position of the bearing support bracket 32, and the left and right bearing units 31 can be easily aligned to simplify the assembly work. Will be able to.
[0049]
The charging unit 7 is provided on the upper surface of the main body case 8 and is provided with a charging lid 38 for charging an organic substance into the treatment tank 9, and is provided in a peripheral portion of the charging lid 38 and when the charging lid 38 is closed, the main body case 8. A packing 39 or the like is provided to prevent outside air from entering the apparatus from the charging lid 38 by being in close contact therewith.
[0050]
FIG. 11A is a view showing a state when the closing lid 38 is opened, and FIG. 11B is a view showing a state when the closing lid 38 is closed.
[0051]
The charging lid 38 is a heat insulating lid formed of an inner lid 40 and an outer lid 41, and is provided with a hinge 42 on the rear end side so as to be opened with respect to the main body case 8, and a handle 43 on the front end side. Is provided so that the handle 43 can be lifted to open the insertion lid 38.
[0052]
12A is a perspective view of the outer lid 41, and FIG. 12B is a sectional view thereof. 12C is a perspective view of the inner lid 40, and FIG. 12D is a sectional view thereof.
[0053]
A recess 44 is provided on the hinge 42 side of the inner lid 40 so that a filter handle 59 to be described later does not come into contact therewith. The packing 39 is provided so as not to include the recess 44.
[0054]
As can be seen from the figure, the depression 44 is formed by bending the plate material forming the inner lid 40 into a concave shape, and there is a concern that the strength of the charging lid 38 may be reduced. Therefore, the left and right side plates 40 a and 40 b of the inner lid 40 are extended to the rear side plate 40 c so as to surround the recess 44, thereby preventing such strength reduction.
[0055]
FIG. 13 is a detailed view of the closing lid 38 with the hinge 42 as the center. A magnet 45 is provided in the vicinity of the filter handle 59 and a first switch 46 is provided on the inner lid 40 at a position facing the magnet 45.

[0057]
FIG. 14A is a top view of the discharge unit 6, FIG. 14B is a front view thereof, and FIG. 15 is a side view of the discharge unit 6. At this time, in FIG. 14B, the door cover 54 is omitted, and a handle position regulating rib 64 and a key 62 described later when the door cover 54 is closed are indicated by dotted lines. 16A is a perspective view of the chute 51, and FIG. 16B is a perspective view of the door cover 54.
[0058]
The discharge door 53 has a handle 52 and a discharge door lock 55. A handle 56 is provided at one end of the handle 52 and a roller 57 is provided at the other end. Further, the discharge door lock 55 is a screw type, and when tightened, the tip of the screw hits the discharge door 53 so that the discharge door 53 does not move.
[0059]
Then, when the handle 52 is rotated (the handle 56 is pushed downward) with the discharge door lock 55 loosened, the roller 57 of the handle 52 is guided by the guide member 58 fixed to the discharge door 53, and the guide The member 58 moves so as to lift up, whereby the discharge door 53 moves upward and the discharge port 49 is opened.
[0060]
On the other hand, when closing the discharge door 53, the reverse is true. When the discharge door 53 is kept closed, the discharge door lock 55 is tightened.
[0061]
At this time, the opening of the discharge chamber 12 and the opening of the main body case 8 are connected by a chute 51 having a swash plate 50 inclined downward so that the processed material can be smoothly taken out.
[0062]
By the way, when the chute 51 is only the swash plate 50, there is a problem that the processed material spills from the left and right ends of the swash plate 50, and the processing tank 9 and the main body case 8 are not in close contact with each other. Therefore, there is an inconvenience that outside air enters the apparatus and cools the treatment tank 9 and the like.
[0063]
In order to cope with such inconvenience, side plates 50a, 50b, and 50c are provided on the swash plate 50 as shown in FIG. 16 so that the gap between the processing tank 9 and the main body case 8 is closed.
[0064]
The discharge door 53, the handle 52, and the like are covered with a door cover 54, and the door cover 54 is provided with a key 62 so that the handle 52 is not inadvertently operated.
[0065]
As shown in FIG. 16, the door cover 54 is a single-sided door, and the side plate 54a on the hinge side and the upper side plate 54b are fixed to the main body case 8, and the side plate 54c and the lower side plate facing the side plate 54a on the hinge side. 54d is fixed to the front plate 60 so that the front plate 60 can be opened and closed.
[0066]
Further, an overhang plate 61 is provided on the upper side plate 54 b, and a key 62 is engaged with the overhang plate 61. The key 62 has an engaging piece 63, and the locking is performed by rotating the engaging piece 63 and positioning it on the back surface of the overhanging plate 61.
[0067]
A handle position regulating rib 64 that regulates the position of the handle 52 is provided on the back surface of the front plate 60 in the door cover 54.
[0068]
FIG. 17 is a view showing an example of a failure that occurs when the door cover 54 is closed when the handle position restricting rib 64 is not provided. FIG. 17A is a top view and FIG. 17B is a front view. is there. By the way, FIG. 17 corresponds to FIG. 14, so that the operation of the handle position regulating rib 64 can be easily understood by comparing these figures. In FIG. 17B, the door cover 54 is omitted as in the case of FIG. 14B.
[0069]
Normally, the discharge door 53 is closed after the processed material is discharged from the treatment tank 9, but sometimes the discharge door 53 is forgotten to be closed.
[0070]
However, if the handle position regulating rib 64 shown in FIG. 17 is not provided, the door cover 54 will be closed even if the discharge door 53 is forgotten to close. The processed product is discharged from the processing tank 9 and is dammed by the door cover 54 by operating.
[0071]
If the door cover 54 is opened without knowing that it is in such a state, a large amount of processed material spills out of the machine, and the heat of the outside air is directly transmitted to the processing tank 9 through the door cover 54. The said processing tank 9 will be cooled and processing efficiency will fall.
[0072]
Therefore, a handle position regulating rib 64 is provided, and even if the door cover 54 is to be closed when the discharge door 53 is not closed, that is, when the handle 52 is not positioned at a predetermined position above, the handle position regulating rib 64 is It does not close by hitting 52.
[0073]
Since the open / closed state of the door cover 54 can be confirmed from the outside, it is possible to easily know the open / closed state of the discharge door 53 and to prevent the inconveniences described above.
[0074]
Further, in the case where the handle position regulating rib 64 is not provided, it may be assumed that even if the discharge door 53 is closed, if the forgetting to close the discharge door lock 55, vibration or the like is transmitted from the outside to the apparatus for some reason and the handle 52 moves. In such a case, the state is substantially the same as forgetting to close the discharge door 53.
[0075]
However, by providing the handle position restricting rib 64, even if the handle 52 is about to move due to external vibration or the like, the handle position restricting rib 64 restricts this movement, so that such inconvenience can be prevented. Yes.
[0076]
In addition, since the door cover 54 covers the discharge door 53, it becomes a double door substantially, and the heat of outside air is not directly transmitted to the processing tank 9. Accordingly, it is possible to prevent a reduction in processing efficiency due to the provision of the discharge door 53.
[0077]
The deodorization unit 5 includes a heater 65 that heats the exhaust gas, a deodorizer 66 that is disposed on the leeward side of the heater 65 and deodorizes the gas heated by the heater 65, the heater 65, and the deodorizer. 66, a storage box 67 for storing 66, a storage lid 68 as a lid thereof, and the like.
[0078]
18 is an exploded perspective view of the deodorizing unit 5, FIG. 19 is a top view of the deodorizing unit 5, and FIG. 20 is a diagram showing an internal configuration of the deodorizing unit 5.
[0079]
The heater 65 is formed by forming a plurality of ventilation holes 70 in a rectangular parallelepiped 69 made of quartz or ceramic and passing the nichrome wire 71 therein, and is stored in a storage box 67 via a heat insulating material 72.
[0080]
Further, the deodorizer 66 is provided with a catalyst 73, and this catalyst 73 is a columnar one formed with fine honeycomb-shaped vent holes 74 and is accommodated in a storage box 67 via a heat insulating material 75.
[0081]
Then, the exhaust gas from the treatment tank 9 is supplied to the heater 65 through a filter, and the exhaust gas heated by the heater 65 is supplied to the deodorizer 66 and deodorized.
[0082]
At this time, since the exhaust gas is heated by the heater 65, the temperature of the exhaust gas supplied to the deodorizer 66 is high, thereby promoting the decomposition reaction of the exhaust gas by the catalyst 73 and the deodorization efficiency. Has come to improve.
[0083]
The storage box 67 is covered with the storage cover 68 as described above, and the storage cover 68 is provided with a storage cover closing prevention cover 76 and a one-touch lock 77 for engaging the storage cover 68 with the storage box 67 is provided. It has been.
[0084]
The one-touch lock 77 is fixed to the storage lid 68, is provided with a hook 78, is fixed to the lever 80 urged by a spring 79, and the storage box 67, and is engaged with an engaging claw 81 and a hook 78. And a non-engagement preventing member 82 for preventing the storage lid closing / forgetting prevention cover 76 from being closed even when the lever 80 is closed when the engaging claw 81 is not normally engaged.
[0085]
As a result, the lever 80 is opened (the lever 80 is raised), the hook 78 is engaged with the engaging claw 81, and the lever 80 is closed (the lever 80 is laid down) to fix the storage lid 68 to the storage box 67. .
[0086]
Conventionally, since the storage lid 68 is screwed to the storage box 67, the maintenance work is troublesome. However, the above configuration improves the workability because the storage lid 68 can be opened and closed with a single touch.
[0087]
FIG. 21 is a view for explaining the action of the non-engagement preventing member 82 when locking the storage lid 68. FIG. 21 (a) shows the case where the non-engagement preventing member 82 is not provided. FIG. 6B shows a state when the lever 80 is closed in a state where the hook 78 and the engaging claw 81 are not engaged when the non-engagement preventing member 82 is provided. In the figure, a dotted line indicates the storage lid closing / forgetting prevention cover 76. FIG. 21C is a top view of the engaging claw 81.
[0088]
As can be seen from FIG. 21A, the lever 80 can be closed even when the hook 78 is not engaged with the engaging claw 81 or when the engagement is incomplete. However, in this state, since the storage lid 68 is not completely closed, outside air enters the storage box 67 and cools the heater 65 and the like, causing heat loss.
[0089]
Therefore, as shown in FIG. 21B, a non-engagement preventing member 82 is provided to prevent such a state, and the hook 78 is not engaged when the engagement between the hook 78 and the engagement claw 81 is incomplete. The storage cover closing preventive cover 76 hits the protruding hook 78 so that it does not close.
[0090]
Since the storage lid closing / forgetting prevention cover 76 is screwed to the main body case 8, the main body case 8 is not normally closed when the storage lid closing / forgetting prevention cover 76 is not normally closed. Therefore, it is possible to determine the engagement state between the storage lid 68 and the storage box 67 based on whether the main body case 8 is normally closed.
[0091]
The main body case 8 and the storage lid closing forgetting prevention cover 76 are screwed as described above, but the main body case 8 and the storage lid are closed in order to prevent the heat of the deodorizing unit 5 from escaping to the outside air. A heat insulating member 83 is disposed between the anti-forgetting cover 76 and a female screw is formed on the connecting member 84 having a low thermal conductivity such as ceramics, and the housing lid is closed from the main body case 8 side to the female screw. The male screws 85 are screwed together from the prevention cover 76 side, and these male screws 85 are prevented from contacting each other.
[0092]
The ventilation unit 4 sucks outside air into the treatment tank 9, and then exhausts the dust 86 contained in the air sent from the treatment tank 9 to the deodorization unit 5 by the fan 86 that exhausts the deodorization unit 5 and the double bottom of the treatment tank 9. A filter 87 to be removed is included.
[0093]
As shown in FIG. 22, the filter 87 is formed by placing a mesh-like net 89 on the bottom side of a boat-shaped frame 88 and placing a non-woven fabric or the like thereon, and a filter handle on the top of the frame 88. 59 is provided. Such a filter 87 needs to be regularly cleaned and replaced.
[0094]
The filter 87 is inserted into and attached to a filter insertion port 90 provided in the main body case 8 at a position corresponding to the recess 44 of the inner lid 40 in the charging lid 38.
[0095]
At this time, a guide 91 is provided in the filter insertion port 90 so that the filter 87 can be smoothly mounted.
[0096]
As described above, the magnet 45 is provided on the handle 59 of the filter 87, the first switch 46 is provided on the inner lid 40 at a position facing the magnet 45, and the second switch is provided on the main body case 8 side. 47 is provided.
[0097]
The first switch 46 and the second switch 47 are set to be “ON” when receiving a magnetic field. For example, when the closing cover 38 is opened, the first switch 46 changes the magnetic field of the magnet 45. When the closing lid 38 is closed, the first switch 46 receives the magnetic field of the magnet 45 and is turned “ON”.
[0098]
When the state in which the first switch 46 is “OFF” and the second switch 47 is “ON” continues for a predetermined time (a time sufficient to throw organic matter such as garbage) into the treatment tank 9, the loading lid 38 is reached. It is determined that the closing lid 38 is forgotten, and an alarm is output, thereby preventing the closing lid 38 from being forgotten to close.
[0099]
If both the first switch 46 and the second switch 47 remain “OFF” for a predetermined time (for example, the time required for replacing the filter 87), it is determined that the filter 87 is not attached and an alarm is output. As a result, operation without the filter 87 is prevented.
[0100]
Further, when the second switch 47 is in the “ON” state for a predetermined time (for example, a period during which the filter 87 is maintained), it is determined that the maintenance of the filter 87 has been forgotten, and an alarm is output. The filter 87 is prevented from being used without being washed.
[0101]
Note that these alarms are output by a warning means such as a buzzer or light such as an LED based on signals from the first switch 46 and the second switch 47.
[0102]
Next, the operation of the organic matter processing apparatus having such a configuration will be described including the steps of sucking and exhausting outside air. First, the input lid 38 is opened, and an organic substance such as garbage is input into the processing chamber 11 of the processing tank 9 and the input lid 38 is closed.
[0103]
At this time, if the closing door is forgotten to close, the first switch 46 does not receive the magnetic field, so an alarm is given based on the signal from the first switch 46 that the closing door is open.
[0104]
The filter 87 needs to be periodically cleaned and replaced. If the filter 87 is forgotten to be remounted in such a cleaning operation, the first switch 46 and the second switch 47 receive a magnetic field. Since there is no filter 87, it can be determined that there is no filter 87, and the alarm device outputs an alarm to that effect based on the signals from the first and second switches 47.
[0105]
Since the filter 87 must be set during operation of the apparatus, the handle 59 of the filter 87 is covered with the charging lid 38. Therefore, there is no fear of removing the filter 87 inadvertently.
[0106]
The charged organic substance is mixed with the processed substance in the processing chamber 11 by the stirring body 10 and decomposed by the carrier to become a processed powder product.
[0107]
In addition, since a large amount of moisture is attached to the newly introduced organic matter, there is a concern that it will adhere to the inner wall of the processing tank 9, but the inner wall of the processing chamber 11 is coated with the stagnation prevention member 21. Therefore, stagnation of organic substances is suppressed. Therefore, the organic matter is not burned and the microorganisms are not killed.
[0108]
Thereafter, the processed material is transferred from the processing chamber 11 to the discharge chamber 12 through the transfer port 15 by the movement of the stirring body 10 and waits for discharge.
[0109]
When taking out the processed product, the key 62 of the door cover 54 is unlocked, the door cover 54 is opened, and the discharge door lock 55 is loosened. Then, the handle 52 is turned to open the discharge door 53.
[0110]
As a result, the processed material in the discharge chamber 12 is discharged to the outside of the machine by sliding on the swash plate 50 from the discharge port 49 by the movement of the stirring body 10, so that the processed material is stored in the swash plate 50 with the garbage bag or the like. .
[0111]
Since the gap formed between the opening on the processing tank 9 side and the opening on the main body case 8 side is blocked by the side plates 50a, 50b, 50c and the swash plate 50 that constitute the chute 51, the outside air enters the apparatus. There is no such thing as intrusion and cooling of the treatment tank 9 and the deodorizing part 5.
[0112]
When the discharge of the processed material is completed, the handle 52 is raised, the discharge door 53 is closed, and the discharge door lock 55 is closed. Then, the door cover 54 is closed.
[0113]
At this time, if the discharge door 53 is forgotten to be closed or cannot be completely closed, the handle position restricting rib 64 provided on the door cover 54 abuts the handle 56 of the handle 52 so that the door cover 54 cannot be tightened and locked. . Therefore, it is possible to prevent the discharge door 53 from being forgotten to be closed or incomplete.
[0114]
Further, even if external vibration or the like is applied to the apparatus, the position of the handle 52 is restricted by the handle position restricting rib 64, so that the discharge door 53 does not open.
[0115]
On the other hand, the outside air is sucked into the control unit 92 from the intake port 93 by the exhaust fan 94 provided in the control unit 92, cools the electrical components such as the triac, and is heated and deodorized by the deodorization unit 5, and then the piping. After facing 110, the air flows into the space in which the fan 86 and the agitation motor 24 are housed, absorbs heat generated from them, and becomes hot air and flows into the treatment tank 9 from the in-machine intake port 111.
[0116]
Accordingly, heat that is originally discarded is recovered and high-temperature air is supplied to the processing tank 9, so that the thermal efficiency can be improved.
[0117]
In the treatment tank 9, microorganisms are activated by the oxygen in the supplied air, and the organic matter is decomposed into a processed powder product. At that time, since a gas with bad odor is generated, this exhaust gas is guided to the heater 65 in the deodorizing section 5 and heated by the heater 65 to enhance the deodorizing action by the deodorizer 66 and deodorize.
[0118]
Since the temperature of the exhaust gas deodorized by the deodorizing unit 5 is sufficiently high, exhausting it as it is will lower the thermal efficiency. On the other hand, the treatment tank 9 needs to raise the temperature of the treatment tank 9 in order to activate microorganisms and increase the decomposition treatment speed.
[0119]
Therefore, the hot exhaust gas from the deodorizing unit 5 is guided into the double bottom of the processing tank 9, where the processing tank 9 is heated and finally discharged from the chimney 95.
[0120]
At this time, if a large temperature distribution is generated by the high temperature exhaust gas being blown to a part of the bottom of the treatment tank 9, there is a risk that organic matter in the treatment tank 9 may be burned or microorganisms may be killed. The double bottom is provided with the air distribution plate 18 and the soaking member 20 so that the exhaust gas uniformly blows to the bottom of the treatment tank 9 and the heat spreads quickly throughout. Yes.
[0121]
In the above description, the case where the filter 87 is manually detached and maintenance such as cleaning is performed has been described, but a configuration described below may be employed.
[0122]
That is, as described above, since dust such as a processed material adheres to the filter 87, maintenance such as cleaning is necessary periodically. However, when this is as short as one week, such maintenance work is troublesome. It may become.
[0123]
In such a case, as shown in FIG. 23, it is possible to remove dust adhering to the filter in conjunction with the charging lid 38.
[0124]
That is, a filter having a one-way cam (not shown) that rotates in conjunction with opening and closing of the closing lid 38, a tooth-like roller 96 that rotates only in one direction, and a belt-like filter 97 on the main body case 8 side. A unit 98 is provided.
[0125]
The filter unit 98 is stretched by two opposed filter rotation shafts 103, and a gear roller 99 is fixed to one filter rotation shaft 103.
[0126]
For example, when the closing lid 38 is closed, the toothed roller 96 is engaged with the end portion of the closing lid 38 and is rotated, whereby the gear 97 is rotated, whereby the filter 97 is rotated.
[0127]
Since the duct connection portion 100 is in contact with the filter 97, dust adhering to the filter 97 is scraped off and removed.
[0128]
It is also possible to automate using the motor 104 as shown in FIG. In such a case, the rotational speed of the filter 97 can be set arbitrarily, so that dust can be sufficiently removed at the duct connecting portion 100 and the motor 104 can be rotated forward and backward.
[0129]
In this case, the operation timing of the motor 104 can be performed in conjunction with the opening / closing operation of the closing lid 38, and if it is operated by a signal from the first switch 46 provided on the closing lid 38 as shown in FIG. In addition, there is an advantage that it is not necessary to set the operation timing of the motor 104.
[0130]
Of course, even when the filter 97 as shown in FIGS. 23 and 24 is unitized, the filter 104 may need to be washed or replaced, or the motor 104 or the like may fail due to unforeseen reasons. The unit can be removed from the extraction cover 105 of the filter unit 98 to perform a desired process.
