Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste treatment device for drying food waste such as kitchen waste produced in a kitchen, and more particularly to drying the food waste by forcibly stirring and passing heated air. The present invention relates to a processing device.

[0002]

2. Description of the Related Art As this seed garbage processing apparatus, there is one already proposed in Japanese Patent Laid-Open No. 96271/1993. As shown in FIG. 1, this one has a bottomed cylindrical drying chamber (1) for accommodating and drying food waste, and this drying chamber.
Stirring blade (4) at the bottom of (1) for stirring food waste
And a circulation passage (2) which is connected to the drying chamber (1) and allows heated air to pass through the drying chamber (1) in the casing (K).

The drying chamber (1) is arranged in an upright posture inside the casing (K), and its open end is opened on the upper surface of the casing (K) so that an input port (for inputting garbage) ( 1
1a), and the inlet (11a) is opened and closed by the lid plate (11). And, the stirring blade (4) is a drying chamber.
It is connected to a drive shaft (41) protruding from the bottom wall of (1) and is rotationally driven by a drive motor (M ₁ ) connected to this drive shaft (41). The circulation passage (2) has a drying chamber.
A fan (F) for forcedly circulating air, a heater (H) for heating the circulating air, and the like are provided in a closed loop composed of (1) and a circulation passage (2).

In this case, the food waste put into the drying chamber (1) is forcibly stirred by the stirring blade (4). Then, in this agitated state, the heated air is forcibly circulated in the closed loop, so that the food waste is dried. As a result, the above-mentioned food waste becomes dry garbage whose volume is significantly reduced. The water vapor generated by this drying is condensed and liquefied by the condenser (71) provided in the circulation passage (2) and discharged to the outside of the machine.

In this case, since the food waste is dried by the passage of the heated air in the state of being forcibly stirred, the heated air easily penetrates into the food waste and the drying efficiency is good. However, this type has a problem that the stirring efficiency by the stirring blade (4) is insufficient. That is, when agitating the food waste by rotating the agitating blade (4), the garbage that comes into contact with the agitating blade (4) or the food waste in the vicinity of the agitating material is circumferentially and upward (in the drying chamber (1)). Ability to move in the axial direction) is given, and this movement is transmitted to garbage in other areas. However, in this case, since the axial direction of the stirring blade (4) and the direction of gravity coincide with each other, the whole gravity is directly used as the movement resistance force against the upward movement force of the above-mentioned raw garbage movement force component. To work. As a result, the upward moving force due to the stirring is not sufficiently transmitted, and the stirring efficiency tends to be insufficient.

Further, the drying chamber (1) is erected upright and the casing is
Since the input port (11a) is provided on the upper surface of (K), the position of the input port (11a) becomes high, and it is difficult to input raw garbage. The present invention has been made in view of such a point,
`` Drive shaft (41) protruding from the bottom wall of the drying chamber (1), which is formed into a cylindrical shape with a bottom and has an opening at the upper end that can be opened and closed to feed food waste (11a). Equipped with a stirring blade (4), and the raw garbage stored in the drying chamber (1) is forced to stir by the rotation of the stirring blade (4) while passing heated air to dry the raw garbage. In the processing device ”, while improving the stirring efficiency by the stirring blade (4),
The task is to make it easy to put in garbage. [Invention of Claim 1]

[0007]

[Technical Means] A technical means of the present invention for solving the above-mentioned problem is to provide a "drying chamber (1) in an obliquely upward posture, and to install the drive shaft (41) of the stirring blade (4) in the drying chamber. It is set to be coaxial or parallel to the body axis of (1).

[0008]

The above technical means operates as follows. Input port
The garbage put into the drying chamber (1) from (11a) is stirred by the rotation of the stirring blade (4). At the time of this stirring, a moving force in the circumferential direction and in the axial direction of the drying chamber (1) is given to the garbage that comes into contact with the stirring blade (4) or the garbage in the vicinity thereof. Is transmitted to kitchen garbage in other areas. In this case, since the drive shaft (41) is set to be coaxial or parallel to the body axis of the drying chamber (1) provided in the inclined posture, the direction of the axis of the drive shaft (41) and the direction of gravity. And become mutually inclined. As a result, the resistance force to the axial movement force described above becomes an axial component of the drive shaft (41) in the gravity.

[0009]

[Effect] With this type, the resistance force to the axial moving force acting on the food waste by the rotation of the stirring blade (4) is only a part of the gravity acting on the food waste, so that the entire gravity is directly applied to the resistance. The resistance is smaller than that in the above-mentioned conventional example which is a force. Therefore, in this product, the axial moving force becomes large, and the stirring of food waste is easily transmitted. This improves the stirring efficiency.

Further, since the drying chamber (1) is in an inclined posture, the charging port (11a) is at a lower position than that in the conventional example in which the drying chamber (1) is in an upright posture. This makes it easy to throw in garbage. [Invention of Claim 2] The invention of Claim 2 is the same as the invention of Claim 1, except that "the drive shaft (41) is projected to the middle of the drying chamber (1) or to the vicinity of the open end, This is equipped with a plurality of stirring blades (4) (4) at predetermined intervals in the axial direction, in this case, the area where the stirring blades (4) (4) are directly contacted and stirred. As a result, the agitation efficiency is further improved because each agitation is propagated to other areas. [Invention of Claim 3] In the invention of Claim 1 or Claim 2, the present invention provides the "drying chamber (1) with heated air at the lowermost part of the boundary between the bottom and the body. Inlet for inhalation (18)
And an outlet (16) for discharging heated air was provided on top of it. ”
In this case, from the inlet part (18) to the drying chamber
The heated air sucked into the inside of the (1) permeates the food waste inside the drying chamber (1) and rises, and further from the outlet (16) to the drying chamber.
It is discharged to the outside of (1).

In this case, since the inlet portion (18) is provided at the lowermost portion of the drying chamber (1), the heated air is easily permeated to the bottom of the garbage in the drying chamber (1). In addition, since the bottom of the drying chamber (1) and the body portion are expanded upward from the inlet (18), the drying chamber (1) should be placed in an upright posture on the bottom when the heated air permeates and rises. The non-penetrated area is less likely to occur as compared with the case where the inlet portion (18) is provided. For these reasons, the degree of contact of the heated air with the food waste in the drying chamber (1) is large, and the drying efficiency is improved.

[0012]

Embodiments of the present invention described above will now be described in detail with reference to the drawings. In this embodiment, as shown in FIG. 2, the drying chamber (1) described above is housed in a casing (K) formed in a rectangular box shape, and the forced circulation heating air is placed in the drying chamber (1).

Further, a drive shaft (41) projects from the bottom wall of the drying chamber (1), and the drive shaft (41) is
It is coaxial with (1) and the tip is located in the middle of the drying chamber (1). A plurality of stirring blades (4) and (4) are continuously provided on the drive shaft (41) at predetermined intervals in the axial direction. Each stirring blade
As shown in FIGS. 2 and 3, (4) is configured to extend at a right angle and radially from the drive shaft (41).
As shown in FIG. 3, the blade (43) is provided with a blade piece (43) projecting obliquely upward from a tip of the blade (4).
In 3), the front surface in the direction of rotation is inclined so that it faces upward.

The drive shaft (41) extends through the bottom wall of the drying chamber (1) and the circulation passage (2) and is connected to a drive motor (M ₁ ) attached to the outer wall of the circulation passage (2). , Is driven to rotate by this drive motor (M ₁ ). Further, the agitating blades (4) (4) on the base end side of the drive shaft (41) have their both edges located near the side wall portion of the drying chamber (1).
(4) The area directly stirred by (4) is large. or,
The length of the most advanced stirring blade (4) on the drive shaft (41) is short. This is because when the food waste is stored in the drying chamber (1), the depth and amount of the food waste accumulated near the input port (11a) becomes small. Is thoroughly stirred. As a result, the weight of the stirring blades (4) (4) can be reduced.

Furthermore, in this embodiment, an air chamber (60) is formed so as to surround the body of the drying chamber (1), and the inlet (60a) of this air chamber (60) is It opens at the bottom of the body of 1). With this configuration, the inside of the drying chamber (1) is kept warm and insulated, and the thermal loss is reduced. An air inlet (22) for communicating the air chamber (60) with the circulation passage (2) opens on the upstream side wall of the fan (F), and the damper (6) is in contact with this. ing. The damper (6) is set to an arbitrary opening by a drive device (62) connected to the damper (6).
In addition, in the air chamber (60), the primary air port of the gas burner (3)
(32) is located.

A discharge port (12) for discharging the dust after the drying process is provided on the side wall of the drying chamber (1) and near the inlet part (18). ) Is openably closed by a bottom lid (13). Then, in a mode that surrounds the bottom lid (13), the cylindrical body (53) is downward from the body of the drying chamber (1).
And a garbage container (5) is installed below the cylindrical body (53). The bottom lid (13) is provided with a lever mechanism (L) for opening it.

[Regarding the Actual Use] In this food waste processing apparatus, food waste is put into the drying chamber (1) through the input port (11a). At this time, since the drying chamber (1) is in the inclined posture, the charging port (11a) is located at a lower position than that provided on the upper surface of the casing (K) as in the conventional example described above.
It becomes easy to do the above.

Then, the cover plate (11) is used for the above-mentioned inlet (11a).
When the drive motor (M ₁ ) is rotated after closing, the food waste in the drying chamber (1) is stirred by the rotation of the stirring blades (4) (4). At this time, the garbage that comes into contact with the stirring blades (4) (4) or the garbage in the vicinity thereof moves from the stirring blades (4) (4) in the circumferential direction and in the axial direction upward. Power is given. Then, this moving power is transmitted to the garbage in other areas. In this one, since the drive shaft (41) is coaxial with the axis of the body of the drying chamber (1) provided in the inclined posture,
The axis of the drive shaft (41) and the direction of gravity are inclined with respect to each other. As a result, the above-mentioned movement resistance force against the axial movement force becomes an axial direction component of the drive shaft (41) in the gravity.

Forced circulation. At the same time as the suction, the air inlet (22)
Fresh air sucked from, and primary air and gas sucked from the primary air port (32) by gas combustion in the combustion section (31), that is, combustion gas, together with the air in the drying chamber (1) Forced circulation. At this time, since the circulating air becomes hot air due to the gas combustion, this is the drying chamber (1)
It is dried by permeating through the food waste inside. In this case, since the inlet portion (18) is provided at the lowermost portion of the drying chamber (1), the drying chamber from the inlet portion (18) is
The heated air sucked into the inside of (1) permeates the inside of the garbage in the drying chamber (1) and rises. As a result, the heated air also penetrates into the lower part of the food waste in the drying chamber (1). Further, since the bottom part and the body part of the drying chamber (1) expand upward from the inlet part (18), the above-mentioned impervious area is unlikely to occur.
For these reasons, the degree of contact of the heated air with the food waste in the drying chamber (1) is significantly large.

Further, the volume expansion of water vapor and the like generated by the drying and the amount of sucked air from the outside of the circulation system become an excess air amount with respect to the amount of air in the circulation system. The discharged amount is discharged from the exhaust circuit (21), and the steam is discharged to the outside of the machine together with the discharged gas. It should be noted that fine particles such as odorous components and dust generated during the above-mentioned drying are generated in the combustion part (3
Since the particles are burned while passing through 1) and are removed by the deodorizing device (7), the fine particles are not discharged to the outside of the machine.
