Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for removing water from garbage generated at home, hotels, restaurants and the like.

[0002]

2. Description of the Related Art Garbage rots and causes a bad odor,
In addition, there is a drawback that it tends to become unsanitary. A disposer that crushes and discharges it to sewage has been used as a device for treating garbage. However, in this type of processing apparatus, all raw garbage is discharged into the sewage, which causes water pollution. Due to this, the use of disposers is prohibited or restricted by law.

[0003] As a garbage disposal device replacing the disposer, dehydration type, compression type, cooling type and incineration type have been developed. In the dehydration type processing device, a high speed rotating dehydration cylinder is provided at the drain port of the sink. The dewatering cylinder is rotated at high speed to dewater the raw garbage supplied from the drainage port. This method can reduce the weight of raw garbage by only about 20%. The compression type squeezes raw garbage with a piston to dehydrate it. This type can reduce the water content by only 40%. The frozen type prevents spoilage and odors by cooling raw garbage. In the incineration type, raw garbage is dehydrated and then incinerated.

A processing device for dehydrating and compressing the garbage can reduce the water content in the garbage, but cannot sufficiently remove the water. For this reason, food waste treated with these devices cannot be handled in the same way as ordinary dried waste. After cooling the cooling type, it must be handled in the same way as ordinary wet garbage.

Since the incineration type can turn garbage into ash,
It has the feature that the amount of dust can be significantly reduced. This method
Achieve ideal characteristics as a processing method. However, incineration of garbage having a high water content requires enormous amount of energy, which significantly increases the running cost. In addition, this type of garbage processing device has a drawback that it cannot be easily installed indoors because a large amount of smoke is emitted when it is incinerated.

An apparatus for drying raw garbage with microwaves has been developed as a raw garbage processing apparatus for solving these drawbacks (Japanese Patent Laid-Open No. 63-84685). Since the raw garbage treating apparatus having this structure can internally heat the raw garbage by the microwave, the moisture of the raw garbage can be vaporized and lost in a short time. Therefore, there is a feature that the running cost can be remarkably reduced.

However, this type of garbage processing device has a drawback that it can be used only for specific garbage. The reason is that when the raw garbage is dried, the previously dried portion is overheated and scorched to generate a noticeable smoke.

The present inventor has, in order to solve this drawback,
We have developed a device for drying raw garbage using a rotating drum that rotates around a horizontal axis. This device has the advantage that it can uniformly dry the whole because it dries the raw garbage while stirring it.

However, in this apparatus, it was necessary to take out the garbage from the rotary drum after drying the garbage. If the dried dust is left without being taken out from the rotary drum, the heated dust will be decomposed to easily give off a bad odor.
The dust that has been dried can be cooled by promptly removing it from the rotating drum. Cooled debris is less likely to rot and can be dried further.

However, since it takes time to dry the garbage with microwaves, it is complicated to wait until it is dried before taking out the garbage. In order to solve this drawback, the present inventor has developed an apparatus for treating food waste having a structure shown in FIG. 7 (Japanese Patent Application No. 2-154530).

In this device, when the rotary drum 1 is normally rotated,
Garbage is not disturbed in the dry case and leaks outside. The structure is such that when the drying case is reversed, it goes out from the drying case. In order to realize this, the rotary drum 1
Is attached to the case so as to be rotatable via a horizontal rotation shaft, and has a reverse rotation discharge port 2 for discharging dust at the time of reverse rotation that is opened on the outer periphery. The reverse rotation outlet 2 has an opening 3 and
It is composed of the partition wall 4 located in the vicinity thereof. Partition wall 4
Are fixed by extending radially from the inner surface of the rotary drum 1. The partition wall 4 is adjusted to have a length such that no garbage is generated from the opening when the rotary drum 1 is normally rotated rightward as shown by an arrow A.

Further, a discharge door 6 is provided at the dust drop port 5 provided below the rotary drum 1. The discharge door 6 has a push arm 7 so that it is opened by the rotating drum 1.
Are connected. The push arm 7 is a rotating drum 1 that rotates in the reverse direction.
It is tiltably connected to the discharge door 6 so as to press the discharge door 6.

In the garbage disposal of this structure, the push arm 7 does not press the discharge door 6 when the rotary drum 1 is normally rotated, that is, the discharge door 6 closes the drop opening 5,
When the rotating drum 1 rotates in the reverse direction, the pushing arm 7 presses the discharge door 6 to open the drop port 5, and the dried dust falling from the rotating drum 1 rotating in the reverse direction is dropped into the storage chamber.

[0014]

The apparatus for treating food waste having this structure is characterized in that it can automatically collect dried dust in the storage chamber. However, the device of this structure has a drawback that the amount of food waste stored in the inner volume of the rotating drum is small. The reason is that it is not possible to store garbage up to the vicinity of the reverse rotation outlet 7. In other words, if there is garbage in the reverse rotation discharge port 7, it will be discharged from the rotating drum that rotates in the normal direction. Further, the device of this structure has a drawback that the mechanism for taking out the dried food waste is extremely complicated, the assembly is troublesome, and it is difficult to perform a reliable operation for a long period of time.

The present invention was developed for the purpose of solving this drawback, and an important object of the present invention is to reliably remove dried raw garbage with a simple mechanism. It is an object of the present invention to provide a raw garbage processing apparatus capable of increasing the amount of raw garbage stored with respect to the volume of a storage container for storing garbage.

[0016]

In order to achieve the above-mentioned object, an apparatus for treating garbage according to the present invention has the following constitution. An apparatus for treating raw garbage includes a dry case 8 shielded by radio waves, a storage container 9 disposed in the dry case 8 for filling the inside with raw waste, and raw garbage stored by moving the storage container 9 The drying case 8 is provided with a driving means 10 for stirring and a high frequency power source 11 for irradiating microwaves.

Further, in the processing apparatus of the present invention, the storage container 9 is a container having an upper opening, and the driving means 10 swings the storage container 9 at a predetermined angle to dry the garbage and then turn it upside down. It is characterized in that it is configured to drop and remove the dried garbage.

[0018]

The apparatus for treating garbage according to the present invention dries the garbage in the following conditions. The storage container 9 is filled with garbage. At this time, preferably, the garbage is put in an air-permeable bag, for example, a water-proof paper bag and filled in the storage container 9. The inside of the drying case 8 is irradiated with microwaves while swinging the storage container 9. Garbage absorbs microwaves and generates heat. The water contained in the garbage is boiled and vaporized to generate water vapor. The water vapor generated in the storage container 9 fills the gap between the garbage. The steam that has boiled from the excessive water content of the garbage is supplied to the overdry area. The portion of raw garbage having a high water content absorbs a large amount of microwaves and generates a large amount of water. When the drying of the raw garbage is completed, the swinging of the storage container 9 is stopped, the storage container 9 is turned upside down, and the stored raw garbage is dropped to the outside of the drying case 8.

The garbage that is dried in this state is prevented from burning in the overdried portion and can be dried uniformly. The reason is that the water vapor evaporated by boiling from the portion having a large amount of water is absorbed by the overdried portion having a small amount of water. In particular, since the raw garbage processing apparatus of the present invention heats the raw garbage while stirring it in the storage container 9, the overdried portion can be made to absorb moisture in an ideal state.

The “column” and the “column of action” are added. However, the members shown in the claims are not limited to the members of the embodiment.

The apparatus for treating garbage shown in FIGS. 1 to 3 is provided in a drying case 8 shielded by radio waves, a high frequency power source 11 for irradiating microwaves in the drying case 8, and a drying case 8. And a storage container 9.

The drying case 8 containing the storage container 9 is composed of a metal casing 13 and a drawer 12, and the storage container 9 is built in the drawer 12. The drawer 12 has a box shape with an upper opening, and is provided so that it can be horizontally taken in and out of the casing 13 via a horizontal rail 14.
With drawer 12 pushed into casing 13, drawer 1
The opening on the upper surface of the upper surface 2 is closed by the ceiling plate 15 of the casing 13. Therefore, in a state where the drawer 12 is pushed into the casing 13, the drawer 12 and the casing 13 form a radio wave shielded room in which microwaves do not leak. As described above, the device in which the storage container 9 is provided in the drawer 12 has a feature that the garbage can be easily put in the storage container 9 by pulling out the drawer 12.

As shown in FIG. 1, the storage container 9 is formed into a cylindrical shape with its both ends closed. The storage container 9 can be formed of synthetic resin or a metal plate. The storage container 9 has an innumerable vent hole so that water vapor generated when drying the garbage can be transmitted. The storage container made of synthetic resin has a property of transmitting microwaves. However, the metal container has a large number of holes larger than the wavelength of the microwave in order to transmit the microwave. Furthermore, at the top of the storage container 9,
The raw garbage supply port 16 is opened.

The storage container 9 is made smaller than the drawer 12, and is set inside the drawer 12 so as to be detachable and swingable. For this reason, the storage container 9 is horizontally extended and fixed to the rotation shaft 17 at the center of the disk that closes both ends. As shown in FIG. 4, the rotating shaft 17 is mounted on a U metal fitting 18 fixed to the inside of the drawer 12 and connected thereto. The U metal fitting 18 has a U shape having an upper opening, and rotatably supports the inserted rotary shaft 17. Therefore, the inner shape of the U metal fitting 18 is designed to be slightly larger than the thickness of the rotating shaft 17.

Further, the storage container 9 is swung in the drawer 12 via the rotating shaft 17 and rotated 180 degrees to be turned upside down. The drive means 10 for swinging and reversing the storage container 9 includes a reversing motor 19 fixed to the lower surface of the bottom plate of the drawer 12, a position detection switch 20 for detecting the rotational position of the storage container 9, and an output shaft of the reversing motor 19.

The drive shaft 21 penetrates the side plate of the drawer 12 and is mounted so as to be rotatable. The part protruding to the drawer 12 is shown in FIG. As shown in this figure, the tip of the drive shaft 21 is provided with a slit 23 in the diameter direction. On the other hand, at the tip of the rotary shaft 17 of the storage container 9, a ridge 24 having a width that can be inserted into the slit 23 is extended in the diameter direction. The slits 23 and the ridges 24 are provided so as to be vertically oriented in this posture so that the storage container 9 can be taken in and out from the U fitting 18 with the storage container 9 facing upward. The drive shaft 21 is rotated by a reversing motor 19 via a pulley and a timing belt 22.

The position detection switch 20 detects the rotation angle of the storage container 9 and the center stationary position, and one switch is provided directly above and two switches are provided on both sides. Position detection switch 20
Detects the rotational position of the storage container 9 via the tilting arm 25 fixed to the drive shaft 21. Therefore, the drive shaft 21
The tilting arm 25 is fixed by extending in the radial direction.
The tilting arm 25 is extended right above and fixed to the drive shaft 21 with the storage container 9 facing upward. The position detection switches 20 on both sides limit the rotation angle of the storage container 9,
The position detection switch 20 immediately above determines the stationary position of the storage container 9.

The reversing motor 19 has a position detecting switch 2
Driving is controlled by a signal of 0. Each time the tilting arm 25 moves to the position detection switches 20 on both sides, the reversing motor 19
Is rotated in the opposite direction to swing the storage container 9. Further, after the drying is completed, the storage container 9 is rotated 360 degrees to drop dust, and then stopped at a position where the tilting arm 25 approaches the position detection switch 20 immediately above.

The apparatus shown in FIG. 1 has a position detection switch 20.
Are arranged within a range of 90 degrees with respect to the drive shaft 21. Therefore, this device reverses and swings the storage container 9 at a rotation angle of 90 degrees. The storage container 9 has a dust supply port 16 opened right above in a range of 90 degrees. The rotation angle of the storage container 9 can be freely adjusted by changing the arrangement positions of the position detection switches 20 on both sides.

At the bottom of the drawer 12, a lid 26 is provided which is opened when the dried dust is dropped. The lid 26 is
When the garbage is dried, it is blocked to prevent the microwave from leaking, and when the dried garbage is dropped, it is opened and dropped into the garbage chamber 34 below. The lid can also be opened by the weight of dust. This lid is closed by a spring and opened by the weight of dust.

Further, the lid 26 can be forcibly opened by an opening / closing motor 27 as shown in FIG. The lid 26 shown in this figure has a pin 29 fixed at its upper end to an arm 28 of an opening / closing motor 27. The pin 29 is inserted into a slit 30 provided in the arm 28 in the radial direction. The pin 29 is pulled up by the arm 28 and the lid 26 is opened. Further, guide ridges (not shown) are fixed to the upper and lower ends of the lid 26, and the side plates of the drawer 12 are provided with guide slits 31 on which the guide ridges slide. The lid 26 includes a guide protrusion and a guide slit 31.
Slide to open and close. The opening / closing motor 27 opens the lid 26 after the drying of the garbage in the storage container 9 is completed and the irradiation of microwaves is stopped, and the storage container 9 is opened in this state.
Rotate 60 degrees to drop the dust into the dust chamber 34, and then block it.

The high frequency power source 11 irradiates the drying case 8 with microwaves. The high frequency power supply 11 is a magnetron 32.
Is equipped with. The magnetron 32 is, for example, 2450
It oscillates a microwave of MHz. The oscillated microwave is sent to the drying case 8 by the waveguide 33.

When the garbage is irradiated with microwaves, the garbage has a microwave irradiation power, a dielectric constant, a dielectric power factor, and
Generates heat proportional to the product of frequency. The product of the dielectric constant and the dielectric power factor changes depending on the type of garbage. For example,
The product of the permittivity and permittivity of water, boiled spinach, boiled potato, and polyethylene is as follows. Water: Boiled spinach: 6.5 Boiled potato: 0.9 Polyethylene: 0.012

The electric power of the microwave applied to the inside of the drying case 8 is adjusted to an optimum value in consideration of the amount of raw dust supplied to the storage container 9 and the drying time.

The high frequency power source 11 having a microwave output of 500 W can vaporize 100 g of water in 10 minutes. Therefore, the output of the high frequency power supply 11 is adjusted within the range of 200 to 2000W.

EFFECTS OF THE INVENTION The apparatus for treating garbage according to the present invention can store a large amount of garbage in a small storage container and can evenly dry the whole, and can reliably remove the dried garbage with a simple mechanism. There is a feature that can be done. The reason why the amount of raw garbage stored in a small storage container can be increased is that the storage container is rocked and agitated instead of rotating the storage container as in the conventional case. Since the storage container accommodating the raw garbage stored in this state is swung without the opening portion facing downward, a large amount of raw garbage can be stored in almost the entire storage container.

Further, the storage container which is opened and swings upward is stopped by swinging and is turned upside down.
Dried raw garbage can be easily dropped. Therefore, the feature that the mechanism for discharging the dried raw garbage can be simplified is also realized. In addition, the simple mechanism also reduces manufacturing costs and also ensures the operation and features of simplifying maintenance.
