DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a microorganism (effective bacterium)
The present invention relates to a garbage disposal apparatus used for reducing and composting garbage by microbial decomposition using garbage.

[0002]

2. Description of the Related Art Conventionally, garbage disposal apparatuses include a heating weight reduction method in which garbage is dried by heat to reduce the weight thereof, and a fermentation treatment method in which garbage is fermented using microorganisms to reduce the weight. The device of the present invention belongs to the latter. Various types of garbage disposal apparatuses for decomposing garbage into carbon dioxide gas and water using such microorganisms (effective bacteria) have been proposed from business use to home use. A porous body to which effective bacteria are fixed in advance as a treatment medium, for example, a decomposition treatment tank for accommodating garbage together with a porous essential chip such as sawdust having effective bacteria fixed therein, and a wood chip in the decomposition treatment tank are provided. A basic configuration is provided with stirring means for mixing garbage.

That is, raw garbage is put into a processing vessel containing microorganisms as seeds in advance, and a rotating shaft equipped with stirring blades is rotated at a constant rotation speed to ferment while mixing and mixing the microorganisms and raw garbage. After the fermentation progresses, the amount of raw garbage is reduced and composted, then the composted garbage is discharged leaving the next seed amount. For example, a device as shown in FIG. 8 is conventionally known as this type of device used for business. The apparatus includes a plurality of agitating blades 24 on a rotating shaft 22 disposed substantially horizontally in a processing tank 28.
The garbage in the processing tank 28 is rotated and stirred in the vertical direction (substantially vertically direction) by the stirring means provided with. In particular, in this apparatus, the treatment tank 28 is
a, a first fermentation tank 28b, a second fermentation tank 28c, and an aging tank 28d, which are divided into four tanks. The raw garbage is sequentially sent to the next tank so that the raw garbage can be fermented continuously and stepwise.

[0004]

However, the conventional garbage processing apparatus has the following drawbacks. (1) A rotating shaft is disposed in a substantially horizontal direction in the processing tank, and garbage in the processing tank is rotated and stirred in a vertical direction (substantially vertical direction). Waste garbage and garbage between adjacent stirring blades cannot be sufficiently stirred. (2) Since the entire stirring means including the support portion of the rotating shaft is always immersed in the waste liquid discharged from the garbage, the stirring means is easily corroded and causes a failure. (3) Fermentation heat is generated when the microorganisms proliferate and become active, and the fermentation heat further promotes the growth and activation. However, in the conventional apparatus, the microorganisms and garbage are simply stirred. Therefore, the heat of fermentation is dissipated and the promotion of fermentation is hindered. (4) Since it is of the type that is sequentially conveyed to the next tank in the horizontal direction, garbage may remain at the bottom of the tank or may be conveyed to the next tank without being sufficiently treated. In addition, the length of the conveying process is increased, and the size of the apparatus is increased. The present invention has been made in view of the above-described disadvantages of the prior art, and can sufficiently stir and mix microorganisms and garbage in the treatment tank, and prevent corrosion of the stirring means,
Further, it is another object of the present invention to provide a garbage disposal apparatus capable of promoting stable fermentation by preventing dissipation of fermentation heat and reducing the size of the apparatus.

Embodiment 1 As shown in FIG. 1, a garbage disposal apparatus according to the present invention comprises a cylindrical tank 8 which is a treatment tank into which garbage is introduced together with microorganisms. The perforated rotary shaft 2 is rotatably supported substantially vertically from the ceiling 9 of the tank 8, and a circular portion on the upper portion of the rotary shaft 2 for leveling the surface of the thrown garbage. Bar-shaped equalizing blade 3
However, a stirring blade 4 is attached to the lower end of the rotating shaft 2 for scooping the garbage that has been thrown in upward.

As shown in FIG. 2, the stirring blade 4 is in the shape of an elongated plate, and is attached to the rotating shaft 2 so as to be vertically inclined. A ventilation tube 6 having a hollow portion 6a communicating with the ventilation hole 1 of the rotating shaft 2 is attached to the back surface 4b of the stirring blade 4 along the length of the stirring blade 4. A plurality of air outlets 5 are provided at predetermined intervals on the opposite side of the direction.

Then, garbage is put into the tank 8, the motor 10 connected to the rotating shaft 2 is driven to rotate the rotating shaft 2, and the air supply blower 11 is further driven to the ventilation hole 1. When aerated, the garbage deposited below the tank 8 is scooped upward while being mixed with the air ejected from the ejection port 5 of the ventilation pipe 6 attached to the stirring blade 4, and the scooped garbage is removed. The leveling blades 3 are pressed down so as to be leveled. The leveling blade 3 is attached at predetermined angles α and β with respect to the rotating shaft 2. According to experiments, α was about 15 degrees and β was about 5 degrees for ordinary garbage such as vegetable waste and garbage.

Since the stirring blades 4 are plate-shaped and attached to the rotating shaft 2 at an angle, the garbage can be scooped. For this reason, when fresh garbage is put into the tank 8 in which the composted garbage containing the seed microorganisms is left, the rotating shaft 2 is rotated, and the garbage is ventilated through the ventilation hole 1, the new garbage is removed. Is stirred up by the stirring blades 4 together with the microorganisms and the air ejected from the ejection port 5 of the ventilation pipe 6, and is scooped upward. Then, the scooped-up garbage is leveled by the leveling blades 3 so as to compress the surface, and the lid is covered, so that the heat of fermentation and dissipation of air can be prevented. Thereby, microorganisms proliferate and activate, and fermentation of garbage is further promoted. In FIG. 1, reference numeral 12 denotes an oil seal.

In this embodiment, as shown in FIG.
An observation window 7 for stirring the garbage in the tank 8 and observing the state of the garbage that is undergoing fermentation is provided on the wall of the tank 8, and the garbage in the fermentation process is visually observed from the observation window 7. Based on the content, for example, normal stage, moist stage,
The state is classified into a plurality of stages such as a sticky stage and a muddy stage, and the number of rotations of the rotating shaft 2 and the ventilation pipe 6 are determined according to each stage.
The amount of air flow from the jet port 5 can be controlled.
For example, as shown in FIG.
Normal button a, moist button b, sticky button c,
An operation panel A on which a muddy button d is arranged is attached, and these buttons a, b, and
By pressing c and d, a signal is sent to the operation circuit of the motor of the motor 10 and the air supply blower 11, the frequency is changed by the inverter, the rotation speed of the rotating shaft 2 and the amount of air supplied from the air supply blower 11. Can be adjusted. For example, as a result of observing garbage through the viewing window 7, when it is determined that the garbage is moist, when the moist button b is pressed, the rotation speed of the rotating shaft 2 increases,
The amount of ventilation from the spout 5 of the ventilation pipe 6 is increased, and the growth and activation of the microorganisms become more active, and the fermentation heat is actively generated, and the excess water is evaporated by the heat. Returns to the normal stage. Therefore, it is not necessary to add a water absorbing agent such as sawdust in order to remove moisture as in the conventional case. In addition, the set value of the rotation speed of the rotating shaft 2 and the set value of the ventilation amount from the ejection port 5 of the ventilation pipe 6 according to the state of the garbage are determined based on the experimental results.

The apparatus of the present invention is provided with a means for preventing corruption and an energy saving means for preventing the garbage from being spoiled even when the garbage is irregularly inputted such that the days when the garbage is not put on during consecutive holidays or long holidays. ing. As the rot prevention means and energy saving means, the apparatus automatically operates for a certain period of time within a day, performs normal operation, and can prevent garbage from rot. For example, a sleep button e is provided on the operation panel A, and a signal is sent from the sleep button e to an operation circuit of the apparatus via a timer so that the apparatus can be turned on and off. To set the timer on / off time,
Determined from experimental results. Experiments have confirmed that it is appropriate to operate about 3 hours per day for ordinary garbage such as vegetable waste and garbage.

[0017]

[Experimental example] First, a dedicated bacterium (microorganism group) blended with thermophilic bacteria, thermophilic bacterium, etc. was placed in the tank 8 of the apparatus of the present invention.
Fill the tank up to about one-third of the height,
Normal garbage such as leftovers is charged, the temperature in the tank is maintained at about 50 ° C., the rotation speed of the rotating shaft 2 is 1/3 rpm,
As a result of continuing the operation for 24 hours by setting the amount of ventilation from the outlet 6 of the ventilation pipe 5 to 0.3 cubic meters per minute,
The water content of the composted garbage was reduced to 30% or less, and it was confirmed that it became a light brown organic fertilizer. In addition, since the effective bacteria (microorganisms) are alive in the organic fertilizer, this organic fertilizer is left as a seed to a level of about one third of the height of the tank 8, and the remaining is removed from the tank 8. It can be taken out and used as a soil conditioner. Therefore, if an effective bacterium is first purchased and introduced, it is not necessary to introduce a new microorganism (effective bacterium) from the next time, which is economical.
In the present embodiment, description of the odor exhaust device and the like is omitted for the sake of simplicity, but it is optional to incorporate these devices.

FIGS. 5 to 7 are a partially cutaway sectional view and a plan view showing a garbage disposal system using the apparatus of the present invention. The same components as those in the first embodiment will be described with the same reference numerals.
