DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a garbage disposal apparatus that decomposes garbage with microorganisms.

[0002]

2. Description of the Related Art A garbage disposal apparatus has been developed in which garbage is decomposed into liquefied matter and gas by microorganisms. This type of garbage processing apparatus stirs garbage in a processing tank. Stirring, for example, rotating a drum-like processing tank,
This is performed by rotating a plurality of stirring plates in the processing tank. When decomposing garbage with such a garbage processing apparatus, garbage and a bacterial bed are introduced from the garbage inlet of the processing tank. The garbage introduced into the treatment tank is agitated, whereby oxygen is supplied to microorganisms (aerobic fermentation bacteria) living on the bacterial bed. The microorganisms supplied with oxygen decompose garbage into liquefied matter and carbon dioxide.

[0003]

However, the liquefied matter discharged from the treatment tank contains a large amount of undecomposed organic substances. If the liquefied product contains a large amount of undecomposed organic substances, the liquefied product produces a bad smell, which gives a person discomfort.

[0004] The present invention has been made in view of the above situation, and has as its object to provide a garbage disposal apparatus capable of preventing the generation of offensive odor.

[0005]

In order to solve the above problems, the garbage disposal apparatus according to the first aspect of the present invention decomposes garbage introduced from the garbage inlet into a liquefied substance by microorganisms. The apparatus includes a processing tank that discharges from the discharge port, and a storage tank that is disposed below the processing tank and temporarily stores liquefied matter discharged from the discharge port. The storage tank is provided with a partition plate for increasing the storage time of the liquefied material. The storage tank of the above-mentioned garbage disposal apparatus is provided with a partition plate for increasing the storage time of the liquefied material. The liquefied matter discharged from the processing tank contains microorganisms together with undecomposed organic substances. Therefore, when the liquefied material is stored in the storage tank for a long time, the microorganisms decompose a large amount of the organic substance in the liquefied material. For this reason, since the amount of organic substances contained in the wastewater from the garbage disposal device is reduced, it is possible to prevent the generation of offensive odor.

The garbage disposal apparatus according to claim 1, wherein the liquefied material is discharged to one end of the storage tank, and a supernatant drain port for draining the supernatant of the liquefied material is provided at the other end of the storage tank. Is preferable (claim 2). In the garbage disposal apparatus thus configured, the liquefied matter discharged from the treatment tank does not immediately drain from the storage tank, but flows from one end of the storage tank to the other end, and then the supernatant drain port Drained through. For this reason, liquefied matter is more decomposed by microorganisms.

In the garbage disposal apparatus according to claim 1 or 2, a forced drainage port for draining the stored liquefied material is provided at the bottom of the storage tank, and a storage plate is provided at the bottom of the storage tank. It is preferable that a through hole is formed near the bottom of the tank (claim 3). The garbage disposal apparatus thus configured can drain the liquefied material from the bottom of the storage tank through the forced drain port. In addition, since the through holes are formed in the partition plate, the liquefied material can be efficiently drained through the through holes.

[0010] In the garbage disposal apparatus according to the third aspect, it is preferable that the forced drain port is provided on a side surface of the storage tank and near the bottom of the storage tank, and the forced drain port and the through hole are linearly arranged. (Claim 4). The garbage disposal apparatus configured as described above inserts a liquefied substance scraping means (for example, an earpick-shaped stick) from a forced drainage port, passes through a through hole of a partition plate, and inserts it into the storage tank, Liquefied matter accumulated on the bottom of the storage tank can be scraped out. Therefore, the storage tank can be easily cleaned.

[0009] In the garbage disposal apparatus according to the fourth aspect, it is preferable that the linear portion connecting the forced drain port and the through hole is lower than the other portion of the bottom of the storage tank. In the above-mentioned garbage disposal apparatus, the linear portion connecting the forced drain port and the through hole is lower than the other portion of the bottom of the storage tank. Since liquefied matter accumulates in the linear portion connecting the forced drainage port and the through hole, which is lower than the rest of the storage tank bottom, it is easier to clean the storage tank by inserting the scraping means from the forced drainage port Can be.

[0010] In the garbage disposal apparatus according to claim 1 or 2, it is preferable that the garbage inlet and the discharge port are arranged at positions displaced in the longitudinal direction of the treatment tank. The above-mentioned garbage disposal apparatus is arranged at a position where the garbage entrance and the discharge port are shifted in the longitudinal direction of the treatment tank. Therefore, the garbage introduced into the processing tank from the garbage inlet is not immediately discharged, but is discharged after moving from the garbage inlet to the discharge port in the longitudinal direction of the processing tank. For this reason, garbage is more decomposed by microorganisms.

According to a sixth aspect of the present invention, there is provided an apparatus for treating garbage, comprising: a stirring plate rotating in the treatment tank; and means for driving the stirring plate. It is preferable to stir while stirring (claim 7). In the above-mentioned garbage disposal apparatus, the stirring plate rotating in the treatment tank stirs the garbage while moving the garbage in the direction of the rotation axis.
Therefore, more agitation is performed while the garbage is moved in the direction of the rotation axis, so that the decomposition of the garbage by microorganisms is further promoted. Here, “rotating in the processing tank” means rotating with respect to garbage in the processing tank, and not only rotating the stirring plate with respect to the processing tank, but also stirring the inner wall of the processing tank. It is intended to include a case where a plate is provided and the processing tank itself rotates.

In the garbage disposal apparatus according to the present invention, it is preferable that the stirring plate is inclined with respect to the rotation axis. The above-mentioned garbage disposal apparatus stirs the garbage while moving the garbage in the rotation axis direction by inclining the stirring plate with respect to the rotation axis.

In the garbage disposal apparatus according to the eighth aspect, it is preferable that a plurality of stirring plates are provided, and that the inclination direction of some of the stirring plates is different from the inclination direction of the other stirring plates. (Claim 9). If the inclination directions of the stirring plates are different, the stirring plates move the garbage not only in one direction of the rotation axis but also in the opposite direction. For this reason, more stirring is performed, and the decomposition of garbage by microorganisms is further promoted.

According to a tenth aspect of the present invention, there is provided a garbage disposal apparatus comprising: a treatment tank for decomposing garbage introduced from the garbage inlet into liquefied substances by microorganisms and discharging the liquefied matter from the outlet; Means for driving the stirring plate. Then, the stirring plate stirs while moving the garbage in the direction of the rotation axis. In the above-mentioned garbage disposal apparatus, the stirring plate rotating in the treatment tank stirs the garbage while moving the garbage in the direction of the rotation axis. Therefore, more agitation is performed while the garbage is moved in the direction of the rotation axis, so that the decomposition of the garbage by microorganisms is further promoted.

[0015] In the garbage disposal apparatus according to the tenth aspect, it is preferable that the stirring plate is inclined with respect to the rotation axis thereof. The above-mentioned garbage disposal apparatus stirs the garbage while moving the garbage in the rotation axis direction by inclining the stirring plate with respect to the rotation axis.

In the garbage disposal apparatus according to the eleventh aspect, it is preferable that a plurality of stirring plates are provided, and that the inclination direction of some of the stirring plates is different from the inclination direction of the other stirring plates. (Claim 12). If the inclination directions of the stirring plates are different, the stirring plates move the garbage not only in one direction of the rotation axis but also in the opposite direction. For this reason, more stirring is performed, and the decomposition of garbage by microorganisms is further promoted.

The set numerical value is determined by pressing the enter button 71d, and the garbage disposal apparatus 10 is operated. When the clear button 71f is pressed, the set numerical value is cleared.

The configuration of the garbage disposal apparatus 10 has been described above. Hereinafter, the operation of the garbage processing apparatus 10 will be described. When processing the garbage by the garbage processing apparatus 10, the open / close lid 14 is opened, a predetermined amount of the bacterial bed is put into the hopper 22, and the electric motor 24 is operated by operating the operation panel 71. When the electric motor 24 is operated,
The screw 26 rotates together with the shaft 27, and the bacterial bed is sent to the tip of the supply pipe 25, and the treatment tank 3 is opened through the opening 25a.
Bacteria beds are supplied within zero. It is desirable that the microbial bed be easily inhabited by microorganisms (aerobic fermentation bacteria) that decompose garbage at a relatively low temperature. For example, rice hulls, wood chips, and sawdust are used. Then, an electric heater (not shown) is energized to raise the temperature in the processing tank 30 to a temperature at which microorganisms actively decompose garbage. However, in the season from spring to autumn, the treatment tank 30 is heated by fermentation heat generated by microorganisms.
It is not necessary to use an electric heater because the temperature inside increases.

Next, garbage and an appropriate amount of P are placed in the hopper 22.
The H adjuster is supplied, the electric motor 24 is operated to rotate the screw 26, and the garbage is supplied into the treatment tank 30. Subsequently, when the electric motor 62 is operated, the processing bath 30 is rotated via the chain 68, and the stirring plate 31 formed on the inner peripheral surface of the processing bath 30 stirs the garbage. As described above, the plate surface 31a of the stirring plate 31 is
The garbage is moved in the direction of the axis 30a of the processing tank 30,
More agitation is performed. With more agitation,
Sufficient oxygen is supplied to the microorganisms in the garbage to promote the decomposition of the garbage. Also, since the inclination (angle 31b) of the plate surface 31a of the stirring plate 31 is opposite every other row,
The garbage does not move in the fixed direction of the shaft 30a of the processing tank 30, but repeats the movement in the direction of the shaft 30a while changing the direction (back and forth). This also contributes to the agitation of garbage.

When the garbage is moved in the direction of the axis 30a of the processing tank 30 by the agitating plate 31, the garbage forms a mountain-like shape below the opening 25a of the supply pipe 25 for supplying the garbage into the processing tank 30. The garbage is flattened without stacking on the garbage. When the upper surface of the garbage is leveled, more garbage can be supplied into the processing tank 30. The rotation speed of the processing tank 30 is 1 to 2 rpm, and after the garbage is sufficiently stirred, it may be rotated only for about 5 minutes per hour. Further, at the same time as the rotation of the processing tank 30, a water opening / closing valve (not shown) is opened, and water passing through the shaft 27 and the hose 74 is sprinkled into the processing tank 30 from the water sprinkling port 72 a of the water sprinkling pipe 72. When water is sprinkled into the processing tank 30,
The decomposition of garbage by microorganisms is promoted. It is desirable that the amount of the bacterial bed and the amount of garbage to be charged into the processing tank 30 is about 1/2 of the height of the processing tank 30 from the viewpoint of the stirring effect. In addition, PH supplied into the processing tank 30
The amount of the adjusting agent is sufficient to neutralize garbage and bacteria beds that become acidic as the garbage is decomposed.

In this manner, the garbage is decomposed in the treatment tank 30 to become a liquefied substance, passes through the liquid permeable plate 34, and falls into the storage tank 42. The liquefied material contains undecomposed organic substances and microorganisms. As shown in FIG. 7, since the supernatant drain port 19 is provided at the upper part of the storage tank 42, the liquid surface 41 of the liquefied material is kept at a position slightly higher than the upper edge 42f of the partition plate 42b. It is. The liquefied material that has fallen from the liquid permeable plate 34 into the storage tank 42 is
a and a gap 42c between the bottom surface 42d of the storage tank 42 and
It passes over the upper end 42f of the partition plate 42b and again passes through the gap 42c between the partition plate 42a and the bottom surface 42d. That is, the liquefied material is retained in the storage tank 42 for a long time while changing its direction up and down, and then drained from the supernatant drain port 19. In addition, the high-viscosity components (such as fats and oils) contained in the liquefied matter adhere to the partition plates (42a, 42b). When the liquefied material stays in the storage tank 42 for a long time and the high viscosity component adheres to the partition plates (42a, 42b), the liquefied material and the high viscosity component are sufficiently decomposed by microorganisms. The liquefied matter decomposed by the microorganism is discharged as a supernatant from a supernatant drain port 19, passed through a hose 15, and guided to the outside of the garbage disposal apparatus 10. As described above, the liquefied material is further decomposed by the microorganisms,
Since the water is drained to the outside, the generation of offensive odor is prevented.

The forced drain port 1 provided in the storage tank 42
8 is normally closed. The handle 18a is operated by the user to open the forced drain port 18 when the storage tank 42 is cleaned. Forced drain 18
Is opened, the liquefied matter in the storage tank 42 is discharged. Then, a long cleaning stick is moved from the forced drain port 18 to the partition plate 42.
a through the through hole 42e of the partition plate 42b, and can be inserted to the end face on the supernatant drain port 19 side of the storage tank 42. When the cleaning rod can be inserted into the storage tank 42, dirt and the like accumulated at the bottom of the storage tank 42 can be scraped. As described above, the storage tank 42
Since the bottom is inclined, scraping of dirt and the like can be easily performed.

When processing the garbage by the garbage processing apparatus 110, the open / close lid 143 is opened, and the garbage, a predetermined amount of a bacterial bed, and a pH adjuster are introduced from the garbage inlet 139, and the shaft 122 is driven. Then, the stirring plate 126 is rotated. At the same time as the rotation of the stirring plate 126, water is sprinkled from a sprinkler pipe (not shown), and when the temperature is low, an electric heater (not shown) is energized to raise the temperature in the processing tank 130. When the stirring plate 126 is rotated, the garbage in the processing tank 130 is stirred. Further, as described above, the stirring plate 12
Since the plate surface 126a of No. 6 is inclined with respect to the axis of the shaft 122, the garbage is also moved in the axial direction of the shaft 122, and the stirring is performed more efficiently. When the garbage is stirred, the decomposition of the garbage by microorganisms is promoted. In this way, the raw garbage is decomposed in the processing tank 130 to become a liquefied substance, which passes through the liquid-permeable plate 145, and
Fall to 2. The fats and oils in the liquefied matter are further decomposed in the storage tank 142 to prevent the generation of offensive odors from the fats and oils, but the details are the same as those of the garbage disposal apparatus 10 of the first embodiment, and therefore the description is omitted. I do.
