BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described below based on the illustrated embodiment. As shown in FIG. 1, a fermentation treatment apparatus according to the present invention contains It has a rotating drum 1 for stirring the garbage (M) to be mixed, and an internal heating mechanism 2 for heating the inside of the rotating drum 1.

The rotary drum 1 has a drum main body 11 and a cylindrical body 12.
2 is heated by the supply of hot air from the internal heating mechanism 2.

The drum body 11 is formed in a substantially cylindrical shape with a bottom and has an opening 11a at an upper end, and accommodates the contents M into and out of the inside through the openings 11a. The lower end is closed by the bottom part 11b, while the thing M can be discharged.

The drum body 11 is rotated by an appropriate drive source 13 about an axis C inclined at an arbitrary angle, and agitates the contents M housed in the inner periphery. The blade 11c is integrally provided.

The inclination angle of the axis C is determined by the function of the blade 11a when the drum body 11 is rotated about the axis while the drum body 11 accommodates the article M. In principle, it may be set arbitrarily as long as it is enough to prevent the contents M from leaking from the opening 11a at the upper end, but from the stirring efficiency, it is set to about 5 to 12 degrees with respect to the horizontal line. Is good.

The drum body 11 has a lower drive shaft 14 supported by a bearing 15 and an upper end supported by a roller 17 adjacent to a guide 16 so as to be rotatable as described above. The bearing 13, the bearing 15, and the roller 17 are connected to a so-called fixed side, which is a frame (not shown) constituting the fermentation treatment apparatus.

The blade 11c rotates together with the rotation of the drum main body 11 about the axis thereof. As is well known, the blades 11c move the contents M in the drum main body 11 at the bottom depending on the rotation direction of the drum main body 11. 11b, or discharges to the opening 11a side. When this functions to press the contents M into the drum main body 11, a so-called destination on the bottom 11b side of the drum main body 11 is formed. Of the empty container M to the drum body 1
In this case, the stirring is performed in a direction perpendicular to the direction of the first axis.

The blade 11c is singularly formed in a spiral shape as shown in the figure. Alternatively, although not shown, a plurality of blades formed in a spiral shape, ie, two blades are formed. May be set in this case, may be set in a parallel mode, or may be set in a mode in which they are arranged in a phase and intersect,
In short, as long as the contents M are stirred as set, the shape and arrangement state thereof may be arbitrarily set.

The cylindrical body 12 is disposed at an axis of the drum body 11 in a state where rotation is prevented while forming an appropriate space between the cylindrical body 12 and the inner edge of the blade 11c. The container M stirred by the blade 11c in the direction perpendicular to the axial direction of the drum body 11 during the rotation of
In the direction along the axial direction of the drum main body 11.

That is, in the illustrated embodiment, the lower end of the tubular body 12 is rotatably connected to the bottom 11b of the drum body 11, while the lower end of the cylindrical body 12 is connected to the connecting portion 12 connected to the upper end.
The upper end of a is non-rotatably connected to a fixed side composed of a pillar P standing on a floor F of a base constituting the fermentation treatment apparatus.

The cylindrical body 12 is set so that, in the above-described supporting state, the lower end is buried in the housing M while the upper end is generally exposed from the housing M. I have.

The connecting portion 12a is connected to the inside of the cylindrical body 12 and the drum main body 11 by hot air from an internal heating mechanism 2 to be described later.
It is set in a pipe shape that can be guided inside.

It is also assumed that the cylindrical body 12 is set in a rectangular cylindrical shape having a certain area, and the presence of this flat surface allows the flow of the contents M in the drum body 1 in the direction perpendicular to the axial direction. Tends to be hindered.

As a result, the contents M flow along the plane of the cylindrical body 12, that is, the opening 1 in the drum body 11.
It tends to flow toward the 1a side, and the stirring effect is improved as compared with the case where the tubular body 12 is not provided.

The blade 11c functions to agitate the contents M in a direction perpendicular to the axial direction of the drum main body 11, but the cylindrical body 12 moves the flow by the blade 11c in the axial direction of the drum main body 11. Therefore, the flow of the storage material M in the drum main body 11 becomes so-called vertical and horizontal, and the stirring effect is improved.

According to the above, it is sufficient that a so-called shield is provided at the axis of the drum body 11.
There is a possibility that the stirring effect is inferior to the case where the cylindrical body 12 is set in a square cylindrical shape. For example, although not shown, the cylindrical body 12 may be set in a cylindrical shape. .

Although not shown, the cylindrical body 12 may be formed in a shape of a pyramid having a thicker lower end, and in this case, the storage material M on the side of the bottom 11b in the drum main body 11 will be described. As the stored amount decreases, the amount of the stored material M flowing in the direction along the axial center line increases, which is advantageous in that the stirring effect on the stored material M is further improved.

Further, although not shown, the cylindrical body 12
Is set to a triangular pyramid, and when one plane is set to a horizontal plane so as to exhibit a so-called inverted triangular shape,
Alternatively, when the shape is set so as to exhibit a triangular shape with the apex facing upward, the amount of material required for forming the cylindrical body 12 is reduced as compared with the case where the cylindrical body 12 is set to have a pyramid shape. This is advantageous in that the size of the cylindrical body 12 can be reduced and the weight of the cylindrical body 12 can be reduced, and the accommodation space in the drum main body 11 can be increased.

In the rotary drum 1 formed as described above, the contents M in the drum main body 11 can be effectively agitated. However, in order to promote the activity of bacteria, an internal heating mechanism is required. 2 is the inside of the drum body 11 and the cylindrical body 1
It is stated that hot air is supplied into the container 2 and the container M itself is maintained in an environment at a temperature and humidity at which bacteria can easily act.

Incidentally, in the illustrated embodiment, the drum body 11 is externally heated not only by the internal heating mechanism 2 but also by the external heating mechanism 3.

The external heating mechanism 3 has a panel heater 31 provided on the outer periphery of the drum body 11 as shown in the figure, and this panel heater 31 is not shown under the control panel 32. It is described that the drum body 11 is heated from the outer periphery by being heated by the heating source.

Incidentally, the internal heating mechanism 2 is provided with an air supply source 21.
And an air supply passage 23 having a heat exchanger 22 and a dehydrator 2
4, an exhaust path 27 having a dust remover 25 and an exhaust source 26.

A deodorizer 28 is connected to the heat exchanger 22 while being connected to the end of the exhaust path 27. An exhaust path portion between the exhaust source 26 and the deodorizer 28 is provided. 27a is communicated with the air supply passage 23 through the communication passage 29.

A brief description will be given below.
1 has a pump 21b that drives the motor 21a and discharges the sucked outside air toward the heat exchanger 22.

Incidentally, in view of the function of the air supply source 21, the air supply source 21 may be provided in an air supply passage 23 to be described later as shown by a dotted line in the figure. Of course.

The heat exchanger 22 is a so-called heater,
In this embodiment, the outside air from the air supply source 21 is almost 80
It is going to be hot.

The air supply passage 23 is for flowing hot air from the heat exchanger 22 toward the inside of the rotary drum 1, and has a base end connected to the heat exchanger 22 and a distal end connected to the cylindrical body 12. It is guided in the connecting portion 12a provided continuously.

The dehydrator 24 is disposed in an exhaust passage 27 to be described later, and functions to separate moisture from hot air returned from the rotary drum 1.

The dust remover 25 is disposed in the exhaust passage 27 downstream of the dehydrator 24, and functions to separate dust from dehydrated hot air.

The exhaust source 26 is disposed in an exhaust passage 27 downstream of the dust remover 25, and is driven by a motor 26a to pump the exhaust gas to a deodorizer 28 under pressure.
b, and acts as a suction machine so as to apply a load so that hot air returning from the rotary drum 1 can pass through the dehydrator 24 and the dust remover 25 described above.

The exhaust path 27 has a base end on the rotating drum 1.
While connected to the side, the tip is connected to a deodorizer 28 described later, while an exhaust path portion 27a between the exhaust source 26 and the deodorizer 28 is connected to the air supply path 23 described above through a communication path 29 described later. It is said that it will be communicated.

At this time, the deodorizer 28 not only performs the deodorization to release the hot air exhausted to the atmosphere, but also emits a considerable amount of heat because it passes the hot air exhausted. That is, in the present invention, the released heat can be used to heat the outside air which is the intake air in the heat exchanger 22.

By providing the communication path 29, the hot air exhausted from the rotary drum 1 can be returned to the air supply passage 23, and the hot air can be reused.

Further, by reusing the hot air, a so-called oxygen deficiency state may be caused in the hot air. However, as described above, since the air supply source 21 replenishes fresh outside air, the hot air is replenished. No oxygen deficiency condition is caused.

By the way, throttles 27b and 29a are arranged in the exhaust passage portion 27a and the communication passage 29, respectively, to prevent generation of noise such as a so-called steam hammer.
