<First Embodiment>
FIG. 1 is an external view of a processing apparatus A according to an embodiment of the present invention that realizes movement amount control of a processing object between processing tanks, and FIG. 2 is an explanatory diagram of an internal structure of the processing apparatus A. In the figure, the arrow Z indicates the vertical direction (the height direction of the processing apparatus A), the arrows X and Y are orthogonal to each other (the X direction is the width direction of the processing apparatus A, and the Y direction is the depth direction of the processing apparatus A). ). The processing apparatus A is a waste processing apparatus for reducing the amount of waste such as garbage.

<Outline of device>
As shown in FIG. 1, a door 1 for opening and closing a loading port 1a for loading garbage is rotatably provided on the upper surface of the processing apparatus A. When the door 1 is closed, a sealing member (not shown) is provided around the door 1 so that the inside of the processing apparatus A is kept airtight.

  An operation unit 3 is also provided on the upper surface of the processing apparatus A. The operation unit 3 is provided with a switch or the like for the user to instruct the processing apparatus A to start and stop processing. On the front surface of the processing apparatus A, an opening 2 for discharging the weight-reduced waste, and a door 2a for opening and closing the opening 2 are rotatably provided.

  Referring to FIG. 2, processing apparatus A includes a bottom plate 4, and a caster 5 is attached to the lower surface of the processing apparatus A to facilitate the movement of processing apparatus A. On the bottom plate 4, partitioning portions 6 to 8 spaced from each other in the X direction are erected. The partition parts 6 to 8 are partition walls fixed to the bottom plate 4. In the processing apparatus A, for example, waste such as garbage is heated as a processing target. Specifically, it is a waste reduction process by a fermentation process as a pretreatment of waste and a drying process as a posttreatment.

  The space between the partition 6 and the partition 7 forms a waste treatment tank 10, and the space between the partition 7 and the partition 8 forms a waste treatment tank 11, and continues in the X direction. These disposed processing tanks 10 and 11 constitute a processing tank for reducing garbage. The treatment tank 11 is further divided into three waste treatment tanks 111 to 113 arranged continuously in the X direction. Details thereof will be described later. In addition, in this embodiment, although the processing tank is divided roughly and it is set as 2 tank structure, it may be divided roughly and it may be set as 1 tank structure, or it is good also as a structure divided roughly and 3 tanks or more.

  A collection chamber 12 partitioned by a partitioning portion 8 is formed on the side of the processing tank 11 in the X direction. In the recovery chamber 12, the reduced waste is introduced from the processing tank 11 (particularly the processing tank 113). The collection chamber 12 communicates with the discharge port 2, and the weight-removed waste can be taken out from the collection chamber 12 by opening the door 2 a.

  The processing apparatus A includes a drive unit 20. The drive unit 20 includes a drive shaft 21 that traverses the processing tanks 10 and 11. The drive shaft 21 extends in the X direction and is rotatably supported by bearings 22 provided in the partition portions 6 to 8 respectively. The drive unit 20 also includes a sprocket 23 fixed to one end portion of the drive shaft 21 and a motor 24. A belt transmission mechanism is configured by winding a belt around the sprocket 23 and a sprocket fixed to the output shaft of the motor 24. The drive shaft 21 is rotated by driving the motor 24.

  In the treatment tank 10, a plurality of stirring rods 25 extending in the radial direction are attached to the drive shaft 21. As the drive shaft 21 rotates, the waste in the treatment tanks 10 and 11 is stirred by the stirring rod 25. A communication hole 71 for communicating the processing tank 10 and the processing tank 11 is formed in the lower part of the partition portion 7, and waste can be transferred from the processing tank 10 to the processing tank 11 by stirring with the stirring rod 25. ing.

  In the present embodiment, the communication hole 71 is provided in the lower part of the partition part 7 so that the waste can be moved from the processing tank 10 to the processing tank 11. However, an opening part is provided in the upper part of the partition part 14, and the partition part If the waste overflows from the treatment tank 10 to the treatment tank 11 beyond 14, the waste may be movable.

  Waste in the processing tank 11, particularly in the processing tank 113, falls into the collection chamber 12 beyond the partition portion 8 due to an increase in the amount of deposition, and accumulates in the collection chamber 12. In this embodiment, the waste can be moved from the processing tank 113 to the recovery chamber 12 beyond the partitioning portion 8, but a communication hole is provided in the lower part of the partitioning portion 8 to be discarded from the processing bath 113 to the recovery chamber 12. The waste may be movable when the material underflows.

  The processing tank 10 is provided with a blower 35. The blower 35 sucks and blows air in the processing tank 10 in a direction indicated by an arrow in FIG. 2 to circulate the air in the processing tank 10. A drying / deodorizing unit 30 is disposed in the space above the collection chamber 12 and the processing tank 11. The drying / deodorizing unit 30 includes a blower 31. The blower 31 sucks the air in the treatment tank 10 through the duct 31 a passing through the partition portion 7 and blows it to the deodorizer 32. The deodorizer 32 includes an oxidation catalyst 32a and a heater 32b that warms air to the activation temperature of the oxidation catalyst 32a.

  A part of the deodorized / heated air passing through the deodorizer 32 is guided to the treatment tank 11 through the duct 32c. A communication hole 72 that allows the processing tank 10 and the processing tank 11 to communicate with each other is formed in the upper portion of the partition portion 7, and the air guided from the duct 32 c to the processing tank 11 passes through the communication hole 72 to the processing tank 10. Inflow.

  The blower 33 sucks the air deodorized and heated by the deodorizer 32 and exhausts it to the outside of the processing apparatus A through the duct 33 a and the ventilation hole 34. The processing tanks 10 and 11 and the recovery chamber 12 are configured to maintain airtightness except for the ventilation hole 34, and outside air corresponding to the amount of air exhausted from the duct 33a is naturally aspirated into the processing apparatus A from the ventilation hole 34. Is done.

<Weight loss treatment>
The processing for reducing the amount of waste such as garbage by the processing apparatus A will be described. Known methods for reducing food waste include a method of simply dehydrating food waste, a method of drying food waste, and a decomposition treatment (fermentation treatment) using microorganisms. In the present embodiment, the weight loss process is a combination of the decomposition process and the drying process, but other methods may be used.

  The garbage thrown in from the loading port 1a enters the treatment tank 10 first. The garbage RD1 containing a large amount of water in the treatment tank 10 is decomposed by the action of a base material that becomes a fungus bed such as microorganisms present in the garbage RD1 or large sawdust previously introduced. At that time, the heated air exhausted from the duct 32c is introduced into the treatment tank 10 through the communication hole 72, whereby the inside of the treatment tank 10 is maintained at a temperature and humidity suitable for activating microorganisms. Further, the uniform decomposition of the garbage RD1 is promoted by the stirring by the stirring rod 25 and the circulation of air by the blower 35.

  By the fermentation of the garbage RD1, the air in the treatment tank 10 has a strange odor, but it is deodorized by the deodorizer 32 and exhausted to the outside of the processing apparatus A, and outside air is naturally aspirated into the processing apparatus A from the ventilation hole 34 The degree is reduced.

  The garbage RD1 in the processing tank 10 that has been reduced in weight as the decomposition process proceeds moves from the processing tank 10 to the processing tank 11 through the communication hole 71 in the lower part of the partition portion 7. The garbage RD2 in the processing tank 11 is dried while moving the processing tanks 111 to 113 mainly by blowing heated air exhausted from the duct 32c. The garbage RD <b> 2 that has been dried and accumulated in the treatment tank 113 overflows from the treatment tank 113 and is discharged into the collection chamber 12. Garbage residue RD3 generated by such weight reduction processing is deposited in the collection chamber 12.

<Details of treatment tank 11>
The structure of the processing tank 11 is demonstrated with reference to FIG.2 and FIG.3. FIG. 3 is a sectional view taken along line II in FIG. As described above, the treatment tank 11 is divided into three waste treatment tanks 111 to 113 arranged continuously in the X direction. Partition sections 13 and 13 are disposed on the virtual boundary surfaces S1 and S2 of the processing tanks 111 to 113, and the partition sections 13 and 13 form partition walls that partition the processing tanks 111 to 113. The partitions 13 and 13 are fixed to the drive shaft 21 and rotate on the virtual boundary surfaces S <b> 1 and S <b> 2 by the rotation of the drive shaft 21.

  When the waste is agitated, the pressure distribution of the waste in the treatment tank fluctuates, and a pressing force acts on the partition portion 13, but the partition portion 13 itself rotates together with the stirring rod 25. Thus, compared with the case of the combination of the fixed partition part 7 and the stirring by the stirring rod 25, the action of the repeated load on the partition part 13 accompanying the stirring in the treatment tank is reduced. Therefore, the partition part 13 can be made lower in strength, and an increase in size and weight of the apparatus can be avoided.

  The lower portions of the treatment tanks 10 and 11 are formed by the wall member 9. As shown in FIG. 3, the wall member 9 has a U-shaped cross-sectional shape with a semicircular lower side. For this reason, the cross-sectional shapes of the treatment tanks 10 and 11 are U-shaped including a semicircular arc-shaped portion at the lower part thereof. The drive shaft 21 is arranged so that the center axis thereof is concentric with the center of the arc-shaped portion, and as a result, the rotation axes of the partition portions 13 and 13 are also concentric.

  The partition 13 has a disk shape, and is fixed to the drive shaft 21 so that the center axis thereof coincides with the center axis of the drive shaft 21. The partition 13 has substantially the same diameter (slightly smaller) as the semicircular portion so that the gap with the semicircular portion of the wall member 9 is as small as possible. Thereby, the movement of the waste through the clearance gap between the partition part 13 and the wall member 9 is prevented between the processing tanks 111, 112, and 113.

  Since the processing tanks 10 and 11 are U-shaped in cross-section, the partition 13 is circular, so that a gap is generated between the partition 13 and the wall member 9 on the upper side of the partition 13. . In this embodiment, the fixed partition 14 is provided to fill this gap. Two fixed walls 14 are provided for each partition 13, and each has a circular arc-shaped notch 14 a concentric with the central axis of the partition 13. A gap between the partition 13 and the inner surface of the treatment tank 111 is filled above the central axis of the partition 13.

  The notch part 14a has substantially the same diameter (slightly larger) as the partition part 13 so that the gap with the partition part 13 is as small as possible. Thereby, the movement of the waste through the clearance gap between the partition part 13 and the fixed partition 14 between the processing tanks 111, 112, and 113 is prevented.

  In addition, when the processing time in each processing tank is comparatively long like a waste processing device, the processing target such as garbage should not move between the processing tanks in a short time. It is desirable to be able to control the amount of movement of objects. However, the waste overflows the partition (using the overflow of the waste into the next treatment tank beyond the partition) or underflow (the waste moves from the gap below the partition to the next treatment tank). It is also possible to control the amount of movement of waste between treatment tanks, but it may be dependent on the amount of waste accumulated in the treatment tank, and it may be difficult to control the amount of movement. is there.

  Therefore, in the present embodiment, the partition portion 13 has a plurality of capturing portions 131. The configuration of the capturing unit 131 will be described with reference to FIGS. 3 and 4A. 4A is a cross-sectional view taken along line II-II in FIG. The taking-in part 131 consists of a set of a communication part 131a and a guide part 131b. In the example of FIG. 3, four capturing portions 131 are provided. Therefore, there are four pairs of communication portions 131 a and guide portions 131 b.

  In the case of this embodiment, the communication part 131a is a rectangular hole penetrating the partition part 13, and communicates between adjacent processing tanks (111 and 112, 112 and 113, the same applies hereinafter) to dispose of waste. Allow movement. In the case of this embodiment, the guide part 131b is a protruding piece that protrudes from the partition part 13. When the rotation direction of the partition portion 13 is the D1 direction, the guide portion 131b guides the waste to the communication portion 131a by the rotation of the partition portion 13 and moves it between the adjacent treatment tanks with respect to the communication portion 131a. It is arranged on the rear side in the direction D1. Moreover, the guide part 131b inclines from the normal line direction of the partition part 13 to the communication part 131a side so that waste can be more efficiently guided to the communication part 131a.

  The operation of the capturing unit 131 will be described with reference to FIGS. 3 and 4B and 4C. 4 (B) and 4 (C) are explanatory views of the action of the capturing portion 131, showing a cross-sectional shape along the line II-II in FIG.

  FIG. 4B shows a case where the partition 13 that partitions the processing tank 111 and the processing tank 112 is rotating in the D1 direction. In this case, the waste in the processing tank 111 is caught by the guide part 131b and guided to the inside thereof, and moves to the processing tank 112 via the communication part 131a as indicated by an arrow.

  FIG. 4C shows a case where the partition 13 that partitions the processing tank 111 and the processing tank 112 is rotating in the D2 direction. In this case, since the waste in the treatment tank 111 rides on the guide part 131b, it is not guided to the communication part 131a as indicated by an arrow. Therefore, there is no or almost no waste moving from the processing tank 111 to the processing tank 112. These actions are the same for the partition 13 that partitions the processing tank 112 and the processing tank 113.

  As described above, according to the present embodiment, the waste can be moved from the processing tank 111 to the processing tank 112 or from the processing tank 112 to the processing tank 113 by the take-in section 131 according to the rotation direction of the partition section 13. Since the amount of movement is proportional to the amount of rotation of the partitioning portion 13 and the like, it is possible to realize control of the amount of movement of waste between the treatment tanks.

<Control unit>
FIG. 5 is a block diagram of the control unit 40 of the processing apparatus A. The control unit 40 includes a CPU 41, a ROM 42, a RAM 43, and an I / F (interface) 44. CPU41 acquires the operation state of the operation part 3 via I / F44, and controls the air blowers 31, 33, 35, the heater 32b, and the motor 24. FIG. The ROM 42 stores control programs executed by the CPU 41 and data. The RAM 43 stores temporary data. The ROM 42 and RAM 43 may employ other types of storage means.

  The control unit 40 changes the rotation direction of the partition unit 13 by switching the rotation direction of the motor 24, and controls the movement of waste from the processing tank 111 to the processing tank 112 and from the processing tank 112 to the processing tank 113. To do. When the waste is not moved, the motor 24 is not driven or the partition 13 is driven to rotate in the D2 direction. When the motor 24 is driven so that the partition 13 rotates in the D2 direction, the movement of the waste in the treatment tank 11 does not substantially occur, but the agitation of the waste in the treatment tank 10 by the stirring rod 25 Done. Therefore, what is necessary is just to rotate the partition part 13 to D2 direction, when only stirring in the processing tank 10 is performed.

  When the partition part 13 is rotated in the D1 direction, the amount of waste that moves through the partition part 13 can be adjusted by the rotation speed of the partition part 13 and the operation time. That is, in the case of fine movement, the rotational speed is relatively slow, or the operation time for rotating the partition 13 in the direction D1 is shortened. When the waste is constantly stirred in the treatment tank 10, the rotation direction of the motor 24 may be switched alternately. The amount of waste that moves through the partition 13 can be controlled by the ratio of rotating the partition 13 in the direction D1.

<Summary>
As described above, in this embodiment, since the partition 13 itself rotates, the action of repeated load on the partition 13 due to the stirring in the treatment tank can be reduced, and the partition 13 can be further reduced in strength. Therefore, it is possible to avoid an increase in size and weight of the apparatus.

  In addition, it is possible to control the amount of waste transferred between treatment tanks. In the present embodiment, the partition portions 13 and 13 have the same configuration, but the capturing portion 131 may be different. With this configuration, the amount of movement of waste from the processing tank 111 to the processing tank 112 and the amount of movement of waste from the processing tank 112 to the processing tank 113 can be made different.

  Moreover, in this embodiment, although the partition parts 13 and 13 were made to rotate with the common drive unit 20, you may make it drive independently by providing a drive unit separately. Thereby, since rotation of the partition parts 13 and 13 can be controlled individually, the amount of movement of waste from the processing tank 111 to the processing tank 112 and the amount of movement of waste from the processing tank 112 to the processing tank 113 are separately set. Can be controlled. Further, in the present embodiment, the partition portions 6, 7, and 8 are fixed, but some or all of them may be rotated with the same configuration as the partition portion 13.

Second Embodiment
In the first embodiment, the communicating portion 131a of the capturing portion 131 is a through hole and the guide portion 131b is a protruding piece. However, the configuration of the capturing portion 131 is not limited to this. FIGS. 6A and 6B are perspective views showing other examples of the partition portion 13.

  The take-in portion 131 of the partition portion 13 in FIG. 6A includes a communication portion 131 a formed as a space extending in the radial direction with respect to the rotation axis of the partition portion 13, and the space 131 a among the partition portions 13. And a guide part 131b formed as an edge part to be defined. The edge part 131b is inclined in the rotation axis direction. When the partition part 13 rotates in the direction of the arrow D1, waste is guided to the gap 131a by the edge part 131b. When rotating in the reverse direction, the waste passes over the edge portion 131b and is not guided to the gap 131a.

  In FIG. 6B as well, the taking-in portion 131 includes a communication portion 131a formed as a space extending in the radial direction with respect to the rotation axis of the partition portion 13, and an end of the partition portion 13 that defines the space 131a. And a guide portion 131b formed as an edge portion. However, in FIG. 6B, the air gap 131a is formed by arranging and combining the blade portions 13a to 13d, which are separate members, in a propeller shape, and each of the blade portions 13a to 13d is the entire guide portion 131b. In this configuration, the waste is guided to the gap 131a. When the partition 13 rotates in the direction of the arrow D1, waste is guided to the gap 131a. However, when the partition 13 rotates in the opposite direction, the waste passes through the blade portions 13a to 13d and is not guided to the gap 131a.

<Third Embodiment>
In the first embodiment, when the partition portion 13 is rotated in the D2 direction, the waste does not move between the treatment tanks. However, when the partition portion 13 is rotated in the D2 direction, the waste is not moved. It is good also as a structure which moves to a reverse direction between process tanks. With this configuration, the waste is not only moved in the direction of the processing tank 111 → the processing tank 112 and in the direction of the processing tank 112 → the processing tank 113 (hereinafter, referred to as a forward direction) depending on the rotation direction of the partition portion 13, but also the processing tank. It can also be moved in the direction of 112 → processing tank 111 and in the direction of processing tank 113 → processing tank 112 (hereinafter referred to as the reverse direction).

  7A shows another example of the partition portion 13, FIG. 7B is a cross-sectional view taken along line III-III in FIG. 7A, and FIG. 7C is a line in FIG. 7A. It is sectional drawing which follows IV-IV. The partitioning section 13 in the figure assumes that the processing tank 111 and the processing tank 112 are partitioned.

  The partition unit 13 includes a capturing unit 131 and a capturing unit 132. The configuration of the capturing unit 131 is the same as that in the first embodiment. The configuration of the capturing portion 132 is the same as the configuration of the capturing portion 131, and includes a communicating portion 132a that is a through hole and a guide portion 132b that is a protruding piece, but the arrangement and the protruding direction of the guiding portion 132b are different. .

  When the rotation direction of the partition part 13 is the D2 direction, the guide part 132b guides the waste to the communication part 132a by the rotation of the partition part 13 and moves it between the adjacent treatment tanks with respect to the communication part 132a. It is arranged on the rear side in the direction D2. Moreover, the guide part 132b protrudes to the processing tank 112 side.

  When the rotation direction of the partition portion 13 is the D1 direction, the waste in the treatment tank 111 is caught by the guide portion 131b and guided to the inside thereof, and the communication portion 131a is passed through as shown by an arrow in FIG. 7B. It moves to the processing tank 112. At this time, since the waste in the processing tank 112 rides on the guide part 132b, it is hardly guided to the communication part 132a.

  When the rotation direction of the partition portion 13 is the D2 direction, the waste in the treatment tank 112 is caught by the guide portion 132b and guided to the inside thereof, and the communication portion 132a is passed through as shown by an arrow in FIG. It moves to the processing tank 111. At this time, since the waste in the processing tank 111 rides on the guide part 131b, it is hardly guided to the communication part 131a.

  Thus, in this embodiment, according to the rotation direction of the partition part 13, waste can be moved to a forward direction or a reverse direction. In this embodiment, the waste is moved from the treatment tank 111 to the treatment tank 112 to the treatment tank 113, but the waste can be moved in the reverse direction, so that each treatment tank can be treated sufficiently. It is possible to reduce the situation where waste that has not been made moves to the next treatment tank. In addition, since the waste can move in the reverse direction, the difference between the forward movement amount and the reverse movement amount becomes the total waste movement amount. Therefore, it becomes easy to move the waste by a minute amount.

  Adjustment of the difference between the amount of forward movement and the amount of backward movement of the waste can be made by controlling the rotation of the partitioning section 13, the structure of the capturing sections 131 and 132, or both.

  For example, the CPU 41 of the control unit 40 makes the rotation time in the D1 direction longer than the rotation time in the D2 direction, and the rotation speed in the D1 direction is higher than the rotation speed in the D2 direction. And a control of increasing the rotation amount in the D1 direction more than the rotation amount in the D2 direction. By such rotation control of the partition unit 13, the amount of waste moved by the capturing unit 131 can be made larger than the amount of waste moved by the capturing unit 132.

  For example, the number of the capturing units 132 may be smaller than the number of the capturing units 131 due to the structure of the capturing units 131 and 132. FIG. 8A shows an example of this, in which there are two capturing units 131 and one capturing unit 132. Therefore, even when the partition 13 is alternately rotated in the rotation directions D1 and D2 for the same time and at the same speed, the amount of movement of the waste by the intake unit 131 is increased.

  As another example, the capturing unit 132 may be smaller than the capturing unit 131. FIG. 8B shows an example of this. The number of the capturing units 131 and the capturing units 132 is the same, but both the communicating unit 132a and the guiding unit 132b of the capturing unit 132 are communicating units of the capturing unit 131. It is smaller than 131a and the guide part 131b. Therefore, even when the partition 13 is alternately rotated in the rotation directions D1 and D2 for the same time and at the same speed, the amount of movement of the waste by the intake unit 131 is increased.

  As another example, the capturing unit 131 may be disposed at a position farther from the rotation axis of the partition unit 13 than the capturing unit 132. FIG. 8C shows an example of this. The number of the capturing portions 131 and the capturing portions 132 are the same and have the same shape, but the capturing portions 131 are disposed at a position R1 away from the rotation axis of the partition portion 13. The take-in part 132 is disposed at a position separated from the rotation axis of the partition part 13 by R2 (<R1). By arranging in this way, the moving speed of the capturing section 131 is faster than that of the capturing section 132 even if the rotation speed of the partition section 13 is the same. Therefore, even when the partition 13 is alternately rotated in the rotation directions D1 and D2 for the same time and at the same speed, the amount of movement of the waste by the intake unit 131 is increased.

<Fourth embodiment>
FIG. 9 is an explanatory view of the internal structure of the processing apparatus B according to another embodiment of the present invention, and FIG. 10 is a cross-sectional view taken along line VV in FIG. The processing device B is different from the above processing device A in the configuration of the partitioning section 13, but the other configurations are the same. Therefore, in the configuration of the processing device B, the same configuration as that of the processing device A is denoted by the same reference numeral and description thereof is omitted.

  Unlike the processing apparatus A, the partition unit 13 of the processing apparatus B does not have the take-in part 131 but has a stirring part 133. In the case of the present embodiment, the stirring unit 133 is a rod-like member protruding in the normal direction of the partition unit 13, but the shape is not limited as long as the processing tanks 111, 112, and 113 can be stirred. Moreover, in this embodiment, although the stirring part 133 is each provided in both surfaces of the partition part 13, what is necessary is just to provide according to the processing tank to stir, and what is necessary is just to provide in at least any one.

  In the processing apparatus B having such a configuration, the waste in the processing tanks 111, 112, and 113 is stirred by the stirring unit 133 by the rotation of the partition units 13 and 13. In the present embodiment, the movement of the waste in the treatment tanks 111 to 113 is performed by overflow due to the stirring of the stirring unit 133.

  When the waste is agitated, the pressure distribution of the waste in the treatment tank fluctuates, and a pressing force acts on the partition part 13, but the partition part 13 itself rotates together with the stirring part 133. Thus, compared with the case of the combination of the fixed partition part 7 and the stirring by the stirring rod 25, the action of the repeated load on the partition part 13 accompanying the stirring in the treatment tank is reduced. Therefore, the partition part 13 can be made lower in strength, and an increase in size and weight of the apparatus can be avoided.

  In addition, in this embodiment, although the partition parts 6, 7, and 8 were fixed, you may make it rotate as a structure similar to the partition part 13 which has a stirring part 133 for some or all of these.

  When the partition 6 is configured similarly to the partition 13 and the processing tank 10 is stirred by the stirring unit 133, the stirring rod 25 can be omitted or at least the number thereof can be reduced. When several stirring rods 25 are provided, it is considered that a load is repeatedly applied to the partition 6 due to the stirring of the waste by the stirring rod 25. However, since the stirring is performed by the stirring unit 133 in the vicinity of the partition 6, the repetition is repeated. It is considered that the load is difficult to act and is small even if it acts.

<Fifth Embodiment>
The first to third embodiments and the fourth embodiment can be appropriately combined. For example, as shown in FIG. 11, the intake part 131 and the agitation part 133 can be provided in the partition part 13. By doing so, waste movement control and stirring in the treatment tank can be performed, and the advantages of each embodiment can be enjoyed.

<Sixth Embodiment>
In the said 1st thru | or 5th embodiment, although the partition part 13 was made into disk shape, the shape is not ask | required. For example, as shown in FIG. 12, a rectangular partition portion 13 ′ is configured to be sandwiched between a pair of auxiliary partition plates 15 having a circular opening 15a concentric with the rotation axis L, thereby separating a partition other than a disk shape. Part can also be adopted. In this case, it is desirable that the gap between the auxiliary partition plate 15 and the partition portion 13 ′ is minute so that waste does not enter.

<Other embodiments>
As mentioned above, although this invention was demonstrated based on 1st-6th embodiment, this invention is not limited to each embodiment mentioned above.

  In the first embodiment and the like described above, the structural example in which the rotation of the partitioning unit 13 is interlocked with the rotation of the stirring unit including the stirring shaft 21 and the stirring unit 25 is, of course, the present invention is not limited to this. For example, while providing a stirring means in the inside of the processing tank which accommodates a process target object, the partition part which divides a processing tank and defines the 1st processing tank and the 2nd processing tank in the said processing tank is a 1st process. You may make it provide rotatably on the interface of a tank and a 2nd processing tank. As a result, internal stress during stirring by the stirring means concentrates on the partition portion or the vicinity thereof, for example, problems such as chipping, cracks, cracks, cracks, partial deformation, etc. (hereinafter referred to as fatigue rupture, etc.) It can be effectively prevented.

  Specifically, when a processing object (for example, garbage) is stirred by the stirring means, the stirring means (stirring unit) proceeds while scraping the processing object, so that the partition plate of the processing tank is a fixed partition. , Internal stress such as local pressure (including frictional force, tensile or compressive stress) is generated on each part of the fixed partition wall and the inner periphery of the tank. Further, such internal stress tends to concentrate on the joint between the fixed partition wall and the tank.

  Furthermore, in the stirring means, for example, when the stirring force is generated by a rotational force or the like, the internal stress described above is repeatedly applied to each part of the fixed partition wall or the inner periphery of the tank according to the rotation or the like. . Therefore, for example, in the fixed partition wall or the joint between the fixed partition wall and the tank, the internal stress (including repeated stress [concentrated load]) is applied to each of those portions, and fatigue fracture or the like may occur. .

  The present invention provides a stirring unit provided inside the processing tank for storing the processing object, and further includes a partition section that partitions the processing tank and defines the first processing tank and the second processing tank in the processing tank. By providing rotation on the boundary surface between the first treatment tank and the second treatment tank, the internal stress at the time of stirring can be dispersed or reduced to effectively prevent the above-described fatigue fracture and the like. By applying such a structure to the above-described embodiments, similarly, fatigue fracture or the like can be effectively prevented.

  In the present invention, the rotation of the stirring means and the rotation of the partitioning portion may be driven by separate drive sources, or they are structured such that both are connected coaxially and interlocked with one drive source. Also good. In any case, according to the present invention, by providing a partition portion that divides one treatment tank to be rotatable, internal stress during stirring can be dispersed or reduced, and fatigue fracture or the like can be effectively prevented. In addition, since the fatigue fracture and the like can be effectively prevented in this way, the structure of the partition portion can be simplified, and the selectivity of the material forming the partition portion can be improved.

  In the first embodiment described above, the example of the structure in which the waste treatment tank 10 is provided with the agitation unit 25 and the waste treatment tank 11 is provided with the plurality of partition portions 13 to be rotatable is described. In the tank 11, a stirring unit 25 may be separately provided between the partitioning units 13. Thereby, it can dry efficiently, stirring a process target object between the partition parts 13 toward the upper part from the bottom face side of the waste treatment tank 11. FIG. In particular, by adopting such a structure, hot air from the upper deodorizer 32 is generated while stirring the object to be introduced (underflow introduction) from the communication hole 71 of the waste treatment tank 11 to the upper side. It is possible to efficiently give the object to be processed, and the processing efficiency can be increased.

  In each of the above-described embodiments, a waste treatment apparatus that treats waste such as garbage as an object to be treated has been described as an example. However, the present invention is not limited to this, for example, a heat treatment apparatus, The present invention can be applied to an agitation processing device, a mixing processing device, a reducing solution processing device and the like.
