DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage disposal apparatus for treating and rendering harmless garbage discharged from homes and the like.

[0002]

2. Description of the Related Art Generally, garbage from households is collected by local governments and collected and disposed of. However, large-scale processing equipment is required, which increases costs, and increases odor and sanitation. Is a social problem.

[0003] Recently, a household garbage disposal apparatus has been proposed in which garbage is accommodated in a treatment tank together with a filler, and the garbage is decomposed by the action of microorganisms.
Various are commercially available.

[0004] For example, Japanese Patent Application Laid-Open No. 5-572 is an example.
No. 65 is known. In this method, a filling material and garbage are stored in a treatment tank, and the garbage is fermented and decomposed and treated while stirring the filler and the garbage in the treatment tank with stirring blades. .

Japanese Patent Application Laid-Open No. Hei 5-221765 discloses that garbage in a treatment tank is stirred by a manual stirring device, and then air is forced into the garbage to ferment the garbage aerobically. An apparatus for disassembly is described.

[0006] In this type of garbage disposal apparatus, when garbage is decomposed by the action of microorganisms, it may be decomposed aerobically or anaerobically. In general, a method of aerobically decomposing in the presence of air is often employed because of the low generation of odor.

In this type of apparatus, the garbage is mixed with a filler such as sawdust to adjust the water content, and in order to activate the aerobic microorganisms, the filler is agitated to generate air therein. While supplying, fresh air is always supplied by ventilating the air in the tank.

[0008]

In this type of garbage disposal apparatus, it is necessary to agitate the filler mixed with garbage in order to aerobically decompose the garbage.
Even if it is stirred more than necessary, it is not possible to improve the decomposition efficiency of garbage, and especially when the temperature is low, mixing excessively cool air into the filler will rather inhibit the activity of microorganisms. It is designed to intermittently stir.

The frequency of the stirring is usually about once every 15 minutes to 2 hours, and the stirring time is about several minutes. At other times, the stirrer is stopped and the garbage is decomposed while the filler remains stationary.

However, in the stirring device, a plurality of stirring blades are radially protruded around the rotary shaft, and the filler is stirred by the stirring blades. From the upper space.

[0011] Since the stirring device rotates in one direction,
If large garbage is mixed in the filler, the garbage may rotate while being hooked on the stirring blade, and the stirring blade with such garbage may protrude from the filler. When stopped, the caught garbage may dry out.

[0012] Once dried, the garbage hardens and the cell tissue hardens, even if the garbage enters the filler by the next stirring, and remains in the filler without being decomposed forever.

The present invention has been made in view of such circumstances, and has as its object to prevent garbage from drying while protruding from the filler and to surely decompose the garbage that has been put in. It is.

[0014]

According to a first aspect of the present invention, there is provided a processing tank for storing a filler and garbage, and a stirrer for stirring the filler and the garbage is provided in the processing tank. A stirrer intermittently driven by a control means, wherein the stirrer comprises a rotating shaft extending in a horizontal direction, and a plurality of stirring blades protruding around the rotating shaft. Is projected from the filler at least at one time of stirring, and the stirring device is controlled to stir for 3 to 10 minutes at an interval of 10 to 120 minutes and to reverse 1 to 3 rotations at the end of the stirring. It is assumed that.

According to a second aspect of the present invention, there is provided a treatment tank for containing a filler and garbage, a stirring device for stirring the filler in the treatment tank, and the stirring device being intermittently controlled by a control means. In the processing apparatus, the stirring device comprises a rotating shaft extending in a horizontal direction, and a plurality of stirring blades protruding within a range of approximately half a circumference of the rotating shaft, wherein the stirring blade has at least stirring. At one time, and control is performed such that all the stirring blades are present in the filler when the stirring device is stopped.

Reference numeral 5 denotes a stirring device provided in the processing tank 3. A plurality of stirring blades 7 are attached to the outer circumference of a rotating shaft 6 extending in the horizontal direction. So that it can be rotated.

Reference numeral 9 denotes a ventilator for discharging the air in the processing tank 3 to the outside and replacing the air in the processing tank 3.

A control circuit 10 controls the driving of the stirring device 5 and the ventilation device 9.
Thereby, the stirring device 5 is intermittently rotated at predetermined time intervals.

The stirrer 5 may be rotated at regular intervals. However, the stirrer 5 may be rotated depending on the outside air or the temperature of the filler 11 stored in the processing tank 3 or the humidity in the space above the filler 11. The stirring conditions of No. 5 can also be adjusted.

In this case, the higher the temperature of the outside air or the filler 11 and the higher the humidity, the more frequently and agitation is performed, and the ventilation volume of the ventilation device 9 is increased. When the temperature is low and the humidity is low, it is preferable to shorten the stirring time, increase the interval, and reduce the ventilation.

A filler 11 such as sawdust is stored in the treatment tank 3 and garbage 12 is put therein. Then, at predetermined time intervals, the stirring device 5 is driven by the drive motor 8.
Is rotated for a predetermined time to stir the filler 11.

At this time, the stirring is performed such that the stirring blades 7 of the stirring device 5 protrude from the filler at least at one stage of the stirring, and the time for stirring the filler 11 is 3 to 10 times.
It is appropriate that the interval is about 10 minutes and the interval is about 10 to 120 minutes.

In this embodiment, the stirrer 5
Is rotated to stir the filler 11 and when the rotation of the stirring device 5 is stopped, the control circuit 10 controls to temporarily reverse the stirring device 5. The time for the reversal is 1
A time of about 3 rotations is appropriate.

The ventilation device 9 is operated to ventilate the air in the processing tank 3. Although the ventilator 9 may be operated at all times, it is preferable to operate the ventilator 9 except during the operation of the stirrer 5 in order to reduce power consumption. The ventilation device 9 can also be operated intermittently.

FIG. 2 shows an embodiment of the second invention. The stirring device 5 in this embodiment has a stirring blade 7 protruding from the outer circumference of a rotating shaft 6 extending in the horizontal direction similarly to the previous embodiment. It is installed only within the range,
There is no stirring blade 7 in the other half circumference.

When the filler 11 is stirred by the stirring device 5, the stirring blades 7 of the stirring device 5 protrude from the filler at least at one time of stirring, and when the stirring device 5 is stopped after stirring, the control circuit 10, all the stirring blades 7 in the stirring device 5 are filled with the filler 11.
It is controlled so that it stops in the state that exists in.
