Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a food waste processing apparatus for decomposing food waste by utilizing the force of microorganisms, and more particularly to a structure of an inspection port portion of the food waste processing apparatus.

[0002]

2. Description of the Related Art Conventionally, it has been practiced to decompose (ferment) food waste containing organic substances and water by using microorganisms to the extent that it does not affect the environment. It has been known. This food waste processing device is filled with wood chips called biochips as food waste processing material in the food waste processing tank, and inputs the food waste into the food waste processing tank from the input port provided in the food waste processing tank. However, the microorganisms that live in the garbage processing material ferment the garbage and decompose it.

However, although the garbage is digested by the microorganisms inhabiting the garbage treating material in the above-mentioned garbage treating apparatus,
Depending on the frequency of use, the bulk of the food waste disposal material in the food waste disposal tank increases little by little. When the volume of the raw garbage processing material in the raw garbage processing tank increases, there is a problem in that stirring and the like are not performed smoothly and the efficiency of the raw garbage processing deteriorates. Therefore,
By installing a processing material discharge tank through a partition plate so as to be adjacent to the food waste processing tank, and providing an opening in the upper part of the partition plate for overflowing the food waste processing material in the food waste processing tank to the processing material discharge tank. The excess food waste processing material in the food waste processing tank is overflowed from the opening to the processing material discharge tank.

[0004]

By the way, in the food waste processing apparatus having such a structure, when performing maintenance of the inside of the food waste processing tank or the inside of the processing material discharge tank, or when replacing the internal garbage processing material. It is done from the inspection port,
When this inspection port is provided in each of the food waste processing tank and the processing material discharge tank, two inspection ports must be provided and two inspection ports must be closed by two inspection port lids, and the structure is complicated. In addition, there is a problem that it is difficult to perform maintenance because a large inspection port cannot be opened.

Therefore, a large inspection port may be provided so as to extend over the food waste processing tank and the processing material discharge tank, and the inspection port may be closed by a large inspection palate. However, it is simply closed by the inspection palate. However, there is a problem that water migrates through the gap between the partition plate between the food waste processing tank and the processing material discharge tank and the inspection lid. In other words, when a large amount of water is put into the food waste treatment tank that is the primary tank, it is the secondary processing material discharge tank (this processing material discharge tank is originally a tank for drying the food waste processing material) The moisture content of the food waste treatment material in the treatment material discharge tank increases, and there is a risk that the water content of the food waste treatment material from the treatment material discharge tank will be received by the bag for the treatment material, etc. There is a risk that the strength of the bag will deteriorate.

The present invention has been made in view of the above-mentioned points, and even if an inspection port is provided so as to extend over the food waste processing tank and the processing material discharge tank, the processing apparatus discharges the processing waste from the food waste processing tank. It is an object of the present invention to provide a food waste processing device capable of preventing water from migrating toward the user.

By fitting the outer periphery of the partition plate 4 between the 9 and sandwiching the outer periphery of the partition plate 4 with the pair of ridges 9, the inspection port 7 is located between the garbage processing tank 1 and the processing material discharge tank 5. However, since there is no gap between the outer periphery of the partition plate 4 and the inner surface of the inspection port cover 8, moisture is absorbed from the raw garbage processing tank 1 as the primary tank to the processing material discharge tank 5 as the secondary tank. Does not migrate, and there is no fear that the garbage processing material having a high water content will be discharged from the processing material discharge tank 5. Further, since the inspection mouth lid 8 is provided with the pair of ridges 9, the ridges 9 function as ribs to reinforce the inspection mouth lid 8.

[0008] According to a second aspect of the present invention, there is provided a food waste disposal device, wherein a container 2 for receiving the food waste disposal material 3 processed in the disposal material exhaust tank 5 is disposed below the disposal material exhaust tank 5.
4 is provided, a discharge port 10 for discharging the raw garbage processing material 3 from the inside of the processing material discharge tank 5 is provided in the inspection mouth cover 8, and a rectangular cylindrical discharge duct 11 communicating with the discharge mouth 10 is provided in the inspection mouth cover 8.
It is characterized in that it is provided integrally with the inspection port lid 8 with the outer surface of the above as one surface, and the discharge duct 11 is communicated with the receiving container 24. The raw garbage processing material 3 is discharged from the processing material discharging tank 5 to the receiving container 24 through the discharge port 10 and the discharge duct 11,

The blades 2 and 16 are rotated to agitate the food waste processing tank 1 and the food waste processing material 3 in the processing material discharge tank 5. The control of the rotation of the stirring blades 2 and 16 is performed by the control unit.

A surface heater is attached to the outer surface of the lower portion of the food waste processing tank 1 so that when the temperature of the food waste processing material 3 loaded in the food waste processing tank 1 is low, it is heated by the surface heater. It has become. Further, in the raw garbage processing tank 1, a raw garbage processing material 3 made of a carrier such as sawdust-like wood chips called a biochip in which microorganisms inhabit is placed. As the raw garbage processing material 3, for example, a conventionally known wood strip (for example, Japanese Patent Publication No. 2-30760) can be used. A water content sensor is provided in the food waste processing tank 1 so that the water content of the food waste processing material 3 in the food waste processing tank 1 can be measured. The control unit can control the rotation of the fan 18, the surface heater, and the stirring shaft 15 based on the water content measured by the water content sensor.

In the above-described food waste processing apparatus, when food waste is put into the food waste processing tank 1, the stirring blade 2 rotates and the food waste and the food waste processing material 3 are agitated and mixed.
Then, the garbage is decomposed by the action of the microorganisms inhabiting the garbage processing material 3. And fan 18
The exhaust of moisture, gas, etc., generated by the processing of food waste in the food waste processing tank 1 is exhausted to the outside via the exhaust path 21, and at the same time the fan 18 is operated to exhaust the air, thereby introducing the intake path. The outside air is supplied from the intake port into the raw garbage processing tank 1 via 19 and fresh oxygen is supplied to the raw garbage processing material 3 to activate the action of microorganisms. As a result, the decomposition processing of food waste is gradually performed. As described above, the raw garbage is treated in the raw garbage treating tank 1, but the amount of the raw garbage treating material 3 increases as the raw garbage is treated. When the amount of the raw garbage processing material 3 in the raw garbage processing tank 1 increases, the excess raw garbage processing material 3 is discharged from the overflow opening 6 to the processing material discharging tank 5. The food waste treatment material 3 discharged to the treatment material discharge tank 5 is heated and dried, or is crushed or decomposed by stirring by the stirring blade 16. The raw garbage processing material 3 processed in the processing material discharge tank 5 is discharged from the discharge port 10 and received by a receiving container 24 such as a receiving bag. The raw garbage processing device operates as described above, and the raw garbage is put in the raw garbage processing tank 1 so that it has a large amount of water. However, since the outer periphery of the partition plate 4 is sandwiched by the pair of protrusions 9, the raw garbage is processed. The harmful effect of water transfer from the waste treatment tank 1 to the treatment material discharge tank 5 is eliminated, and the raw garbage treatment material 3 having a large amount of moisture is received by a receiving container such as a receiving bag and There is no risk of deterioration of strength. Further, the protrusion 9 provided on the inspection lid 8 functions as a rib, and the inspection lid 8 is reinforced.

The inspection port cover 8 is provided with a rectangular tubular discharge duct 11 so as to be integrated with the inspection port cover 8. The discharge port 11 communicates with the upper portion of the discharge duct 11, and the outer surface of the inspection port lid 8 constitutes one surface of the discharge duct 11. In addition, the exhaust duct 11
A flange portion 25 is integrally provided at a lower end of the receiving container 24, and a receiving opening 24a at an upper end of a receiving container 24 such as a receiving bag is attached to the flange portion 25. In the case of this example, a rectangular tubular discharge duct 11 is provided integrally with the inspection port cover 8, and one surface of the discharge duct 11 is the outer surface of the inspection port cover 8. When the processing material 3 is discharged, there is no part where the garbage processing material 3 stays, the food processing material 3 is smoothly discharged, and clogging of the processing material 3 can be prevented. That is, when the discharge duct 11 is provided so as to be separated from the outer surface of the inspection port lid 8 as shown in FIG. 5B, a step portion 27 is formed at the lower edge of the discharge port 10, and the raw garbage processing material 3 is formed on the step portion 27. May get on and get stuck. At this time, the first one to get on the step portion 27 grows and stays as a nucleus. In the present invention, since the step portion 27 as described above cannot be formed, the raw garbage processing material 3 can be prevented from accumulating.
