In the figure, arrow Z indicates the vertical direction (height direction of processing device A), and arrows X and Y indicate horizontal directions perpendicular to each other (X direction is the width direction of processing device A, Y direction is the depth direction of processing device A). ) is shown. The processing device A is a waste processing device that reduces the amount of waste such as garbage.

<Overview of Apparatus> As shown in FIG. 1, on the top surface of the processing apparatus A, there is provided a rotatable input lid 1 that opens and closes an input port 1a into which food waste is input. When the input lid 1 is closed, a sealing member (not shown) is provided around the input lid 1 so that the inside of the processing apparatus A is kept airtight.

At the front of the processing device A, an operation section 3 is provided. The operation unit 3 is provided with a lamp and the like for the user to instruct the processing apparatus A to start or stop processing. Further, a discharge port 2 for discharging the object to be processed that has undergone the weight reduction process, and a door 2a for opening and closing the discharge port 2 are rotatably provided.

Referring to FIG. 2, the processing apparatus A includes a bottom plate 4, and casters 5 are attached to the lower surface of the bottom plate 4, so that the processing apparatus A can be easily moved. On the bottom plate 4, partition walls 6 to 8 are erected in the Z direction and spaced apart from each other in the X direction. The partition walls 6 to 8 are fixed to the bottom plate 4 and partition the inside of the processing apparatus A. In the processing apparatus A, waste materials such as kitchen garbage are heated and processed as objects to be processed. Specifically, it is a process for reducing the amount of the object to be processed through a fermentation process which is a pre-treatment of the object and a drying process which is a post-process.

The space between the partition walls 6 and 7 forms a first processing tank 10, and the space between the partition walls 7 and 8 forms a second processing tank 11. These first treatment tank 10 and second treatment tank 11 provided constitute a treatment tank for reducing the amount of food waste. In this embodiment, the processing tanks are roughly divided into two tank configurations, but they may be roughly divided into three or more tanks.

A storage tank 12 partitioned by a partition wall 8 is formed on the side of the second processing tank 11 in the X direction. The object to be treated, which has been subjected to weight reduction treatment, is introduced into the storage tank 12 from the second treatment tank 11 . The storage tank 12 communicates with the discharge port 2, and by opening the door 2a, it is possible to take out the object to be reduced in size from the storage tank 12.

The processing device A includes a drive unit 20. The drive unit 20 includes a drive shaft 21 that traverses the first processing tank 10 and the second processing tank 11 . The drive shaft 21 extends in the X direction and is rotatably supported by bearings 22 provided on the partition walls 6 to 8, respectively. The drive unit 20 also includes a sprocket 23 fixed to one end of the drive shaft 21 and a motor 24. A belt is wound around the sprocket 23 and a sprocket fixed to the output shaft of the motor 24 to form a belt transmission mechanism. The drive shaft 21 is rotated by the drive of the motor 24.

In the first processing tank 10, a plurality of stirring rods 25 are attached to the drive shaft 21 and extend in the radial direction thereof. Due to the rotation of the drive shaft 21, the objects to be processed in the first processing tank 10 and the second processing tank 11 are stirred by the stirring rod 25. A communication hole 71 is formed in the lower part of the partition wall 7 to communicate the first processing tank 10 and the second processing tank 11, and by stirring with the stirring rod 25, the first processing tank 10 is connected to the second processing tank 11. The object to be processed can be moved to.

The objects to be treated in the second processing tank 11 fall over the partition wall 8 into the storage tank 12 due to an increase in the amount of accumulated objects, and are deposited in the storage tank 12 . In this embodiment, the object to be processed can be moved from the second processing tank 11 to the storage tank 12 over the partition wall 8, but other methods can also be adopted. For example, the object to be processed may be movable by providing a communication hole (communicating portion) in the lower part of the partition wall 8 so that the object to be processed underflows from the second processing tank 11 to the storage tank 12.

In the space above the storage tank 12 and the second processing tank 11, a deodorizing device 32 (heating deodorizing section) housed in a drying/deodorizing unit 30 is arranged. The drying/deodorizing unit 30 has a box shape, and air from a blower 31 is introduced into the unit.

The partition wall 7 is provided with a communication hole 73 that guides the air in the processing tank 10 to the drying/deodorizing unit 30.

A duct 31 a is connected to the communication hole 73 , and the blower 31 sucks air in the processing tank 10 through the duct 31 a passing through the partition wall 7 and blows it to the deodorizing device 32 . The deodorizing device 32 includes an oxidation catalyst 32b and a heater section 32a that heats the air to the activation temperature of the oxidation catalyst 32b.

A portion of the deodorized and heated air passing through the deodorizing device 32 is guided to the processing tank 11 via the duct 31c. A communication hole 72 is formed in the upper part of the partition wall 7 to allow the processing tank 10 and the processing tank 11 to communicate with each other.

A blower 35 is provided at the upper part of the second processing tank 11 . The blower 35 sucks air in the second processing tank 11 and sends it in the direction shown by the arrow in FIG. 2 to circulate the air into the first processing tank 10 through the communication hole 72.

The blower 33 sucks the air deodorized and heated by the deodorizing device 32 through the duct 31b, and exhausts it to the outside of the processing device A through the duct 33a and the ventilation hole 34. The processing tank 10, the processing tank 11, and the storage tank 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 flows into the processing apparatus A from the ventilation hole 34. Naturally aspirated.

Further, the air that has passed through the oxidation catalyst 32b and has been introduced into the reflux passage is led to the processing tank 11 via the duct 31c, and is blown onto the object to be processed RD2 in the processing tank, thereby promoting its drying. Furthermore, a communication hole 72 is formed in the upper part of the partition wall 7 to communicate the processing tank 10 and the processing tank 11, and the air guided from the duct 31c to the processing tank 11 is passed through the communication hole 72 through the blower 35. It flows into the processing tank 10 through the.

The flow of air circulating in the first processing tank 10 will be explained. Air heated by the deodorizing device 32 and blown onto the processed material RD2 in the second processing tank 11 is sucked into the blower 35 and blown toward the first processing tank 10 through the communication hole 72. The wind hitting the surface of the object RD1 flows along the surface of the object RD1. By using the heated air, the processed material RD1 in the first processing tank 10 can be efficiently dried. The wind flowing on the surface of the object to be treated RD1 rises along the partition wall 6 facing the partition wall 7, and is sucked into the communication hole 73 via the duct member 80. In this way, by using the heated and deodorized air to heat the first processing tank 10 and the second processing tank 11 without exhausting it all, the thermal energy of the heater section 32b of the deodorizing device 32 can be used more effectively. , it can be used for heating treatment of objects to be treated.

Next, the configuration of the duct member 80 of the present invention will be explained. The partition wall 7 is provided with a communication hole 72 that serves as a passage for the wind to blow into the first processing tank 10 and a communication hole 73 that sucks the wind inside the first processing tank 10 . The duct member 80 is provided on the first processing tank 10 side so as to cover the communication hole 73, and is provided outside and above the stirring area by the stirring blade so that the processed material does not directly enter when the processed material is stirred. It is being

The air blown from the communication hole 72 circulates within the first processing tank 10 and is taken into the duct member 80 from the inlet portion 82 . Inside the duct member 80 covered by the cover member 81, a plurality of plate members 84 are arranged vertically alternately, and the air flow taken into the duct member 80 is meandered in the vertical direction by the plate members 84. Dust contained in the inhaled air is separated from the air by creating turbulence as the air flow is alternately changed upward and downward inside the duct member.

The air from which dust has been separated flows toward the outlet section 83 from which air is discharged from the duct member. The outlet portion 83 is connected to the communication hole 73, and the air that has passed through the duct member is guided from the communication hole 73 through the duct 31a to the blower 31. At this time, the dust separated inside the duct member 80 falls onto the discharge member 85 and is deposited on the discharge member 85 .

In this embodiment, the duct member 80 is shaped to form a flow path using the wall surface of the first processing tank 10, but it is designed so that the sucked air can be guided to the communication hole 73 and dust can be removed inside. It is sufficient that the duct has a shape such that the duct member alone constitutes the flow path.

Furthermore, as in the present embodiment shown in FIG. 3(a), the duct member 80 may be provided so as to span only one wall surface of the first processing tank, or as shown in FIG. It may be installed so as to hang on the above wall surface. By providing the duct member 80 over multiple walls, the distance through which the air passes through the inside of the duct can be increased, and the number of points where the airflow can be changed can be increased, making it possible to obtain a greater effect of removing dust from the airflow. can.

The operation of the discharge member 85 will be explained. The discharge member 85 is configured to be rotatably movable in conjunction with the opening/closing operation of the input lid 1. In this embodiment, as shown in FIG. 4A, the input lid 1 and the discharge member 85 are connected by a lever member 86, and the discharge member 85 is attached to a hinge member 87. A discharge member 85 is provided below the cover member 81, and when the discharge member 85 is opened, the lower side of the cover member 81 is opened.

As shown in FIG. 4(b), when the user opens the input lid 1 to input garbage, the lever member 86 connecting the input lid 1 and the discharge member 85 pushes the discharge member 85 in the opening direction. The discharge member 85 is rotated and the discharge member 85 is opened. At this time, the dust accumulated in the duct member 80 and the discharge member 85 falls into the first processing tank 10.

When the input of garbage is completed and the input lid 1 is closed, the lever member 86 that is in the state of pushing the discharge member 85 moves in the return direction, the discharge member 85 rotates in the closing direction, and the discharge member 85 is in the closed state. Therefore, the duct member 80 maintains the duct shape.

Further, as shown in FIG. 5, a hinge member 87 with a spring may be attached to the discharge member 85 so that the discharge member 85 is always biased in a direction to maintain the duct shape.

When the user opens the input lid 1 to input food waste, the lever member 86 protruding from the input lid 1 maintains a state in which the discharge member 85 is pressed, and the discharge member 85 opens against the biasing force of the spring. direction, and the discharge member 85 is in an open state. When the input of garbage is completed and the input lid 1 is closed, the lever member 86 that is pushing the discharge member 85 is released, so the discharge member 85 is rotated in the closing direction by the biasing force of the spring and is in the closed state. Therefore, the duct member 80 can maintain its duct shape.

It is sufficient that the discharge member 85 rotates in conjunction with the opening and closing of the input lid 1 by the user, and allows the dust accumulated on the discharge member 85 to fall into the first processing tank 10. The member 85 may be provided with a gear or a motor. When the sensor detects that the input lid 1 is opened, the motor is driven to rotate the discharge member 85 and maintain the open state. When the sensor detects that the input lid 1 is closed after inputting the garbage, the motor is driven to rotate the discharge member 85 to the closed state, and the duct member 80 maintains its duct shape. Good too.

Since the discharge member 85 operates in conjunction with the opening/closing operation of the input lid 1 when the user inputs food waste, the dust accumulated in the duct member 80 and the discharge member 85 can be discharged every time the user performs the input operation. Therefore, the interior of the duct member 80 can be maintained in a clean state.

In this embodiment, the communication hole 72 and the communication hole 73 are provided in the same partition wall, but they may be provided in separate partition walls, for example, the opposing partition wall 6, or they may be provided in adjacent partition walls constituting the processing tank. It may be installed on the partition wall. Further, if a flow path is created in which the air from the communication hole 72 flows toward the communication hole 73, it may be provided using a charging cover instead of the partition wall. In that case, the duct member may be arranged in accordance with the position of the communication hole 73, and the outlet portion may be provided so as to cover the communication hole 73. Further, although a case with a plurality of processing tanks is illustrated, as long as the opening/closing operation of the input lid 1 and the opening/closing operation of the discharge member 85 are linked, a single processing tank may be used.

In the embodiment of the present invention, an underflow configuration is shown in which the liquid is transferred from the processing tank 10 to the processing tank 11 through the communication hole 71 below the bearing 22 of the stirring shaft. The processing method may be another method such as overflow. However, by configuring the two processing tanks to have an underflow configuration, the processing tank 11 is blown with air at a higher temperature than the processing tank 10 to efficiently dry the processed material before being transferred to the storage tank 12. In a configuration in which the heat for heating deodorization of the deodorizing device 32 above the processing tank is used to heat the processing tank, it is better to install the communication hole 73 above the stirring rod 25 of the partition wall 7 to shorten the duct. can.

Further, a blower 35 for blowing the air in the second processing tank 11 toward the first processing tank 10 and a blower 31 for sucking in the air in the first processing tank 10 are provided. In order to balance the pressure inside the first treatment tank 10, fans are installed on both the ventilation and intake sides, but it is recommended to install a fan only on one side, that is, on the ventilation side only, or on the intake side only. However, similar effects can be obtained because circulating air can be created within the processing tank.

In addition, in the above-mentioned embodiment, the waste processing apparatus that processes waste such as kitchen garbage as the processing object is illustrated and explained, but the processing apparatus of the present invention is not limited to this, and for example, heat treatment, etc. Applicable to equipment, stirring processing equipment, mixing processing equipment, solubility reduction processing equipment, etc. Furthermore, the treatment device of the present invention can also be used in various devices other than waste treatment devices.
