DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing apparatus. More specifically, the present invention relates to a garbage processing apparatus that can easily and easily process garbage on the spot where the garbage is generated and that can reduce the burden on the surrounding environment.

[0002]

2. Description of the Related Art Conventionally, garbage discharged from homes and the like is usually separated and collected, incinerated, and then discarded. However, refuse disposal has now evolved into a social problem, and in recent years in which protection of the global environment has been called for, it has become difficult to deal with garbage disposal alone.

Therefore, garbage disposal has begun to be sought in consideration of environmental protection, and attempts to dispose of garbage in places where garbage occurs, such as homes, have been proposed. For example, as an example, as shown in FIG.
A garbage crusher called a disposer that crushes garbage is connected to the sink of a sink, etc., and the garbage is finely crushed by this disposer. A method for treating garbage, in which microorganisms are decomposed by fermentation and water is treated in a water treatment tank and then drained as sewage, and an apparatus therefor has been proposed.

As another method, the above-mentioned method has a drawback that the water after solid-flow separation contains high-concentration organic substances and fine solids, so that the load on the water treatment tank is large. Therefore, as shown in FIG. 3, the garbage was pulverized by a disposer, introduced into a fermentation decomposition tank without solid-flow separation, and decomposed, and only water discharged therefrom was separated into liquids. A method of treating this in a water treatment tank later has also been proposed.

[0005] However, although the latter method is used to reduce the processing load in the water treatment tank, in any case, sludge is inevitably generated in the treatment with microorganisms in the water treatment tank. Therefore, conventionally, as a remedy, in a garbage processing apparatus provided with a disposer (A), a fermentation decomposition tank (A) and a water treatment tank (C) as shown in FIG. Is charged with a treatment carrier loaded with microorganisms for decomposing garbage, rotating the stirring blades (d) by the heater device (e), and rotating the stirring plate (e) at the bottom of the fermentation decomposition tank (a). ) A water treatment tank equipped with an air diffuser (G)
An apparatus has been devised in which sludge (k) and decomposition tank residue generated by the treatment in (1) are returned to the fermentation decomposition tank (a) by a return pump (k), and this is completely decomposed.

[0006]

However, while the above-mentioned remedies are effective in promoting the complete decomposition of sludge, on the other hand, there remains a problem that must be solved in practice. It had been. That is, in the case of the garbage processing apparatus shown in FIG. 4, the sludge (C) from the water treatment tank (C) and the fermentation decomposition tank (B)
To return the decomposition residue from the fermentation decomposition tank (a)
After a certain period of time, for example, about every six months, there is an inconvenience that the entire amount of the treatment carrier charged in the fermentation decomposition tank (a) must be replaced. This means that the load on the processing carrier for sludge to further process the decomposition residue becomes large, and the sludge and the decomposition residue lower the processing performance of the processing carrier for reasons such as impairing air permeability. It was attributable to that.

In the conventional apparatus, the return pump
There is also a problem in that the sludge and the decomposition residue are transported, thereby causing troubles such as clogging of the pump.
For this reason, as a garbage disposal device, the inconvenience in the fermentation decomposition tank associated with the return and accumulation of decomposition residues and sludge is eliminated, and complete decomposition treatment is possible, and most of the processing carriers for fermentation decomposition are replaced. There is a need for a measure for suppressing the occurrence of troubles in the entire system, which is not necessary and has little deterioration in its performance, and which realizes effective garbage disposal.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and has been developed in order to improve the disadvantages of the conventional apparatus, to enable long-term processing, to reduce maintenance labor and cost. It aims at providing a garbage processing device.

[0009]

SUMMARY OF THE INVENTION The present invention solves the above-mentioned problems by providing a garbage disposal apparatus linked to a disposer for crushing garbage, the disposer being connected to a fermentation decomposition tank for garbage. This garbage fermentation decomposition tank is connected to a water treatment tank provided with a sedimentation tank for storing sludge at the lower part of the tank through a perforated plate for solid-liquid separation, and decomposes sludge from the sedimentation tank. The present invention provides a garbage disposal apparatus characterized in that a sludge treatment tank is provided.

In this description, the sludge treatment tank is disposed below the sedimentation tank, and a valve is provided at the discharge port of the sedimentation tank, and the sludge is guided to the sludge treatment tank by opening and closing the valve. Garbage disposal equipment is also provided.

[0011]

According to the garbage processing apparatus of the present invention as described above, the processing apparatus linked to the disposer includes (1) a fermentation decomposition tank for garbage, (2) a water treatment tank, and (3) a sludge treatment tank. A perforated plate for liquid separation is provided between the decomposition tank (1) and the water treatment tank (2), and a sedimentation tank is provided in the water treatment tank (2). The sludge from the settling tank is treated in the sludge treatment tank (3).

For this reason, unlike the conventional apparatus shown in FIG. 4, sludge generated by water treatment and decomposition residue from fermentation decomposition do not need to be treated again in the fermentation decomposition tank. No matter accumulates, there is almost no need to replace the processing carrier, and the performance degradation is reduced.
Further, since no inconvenience such as aeration inhibition occurs, the treated carrier maintains the activity as described above, the shape change is small, and the particle diameter is kept constant, so that the solid-liquid separation becomes easy.

Further, the load on the sludge treatment tank is small, and a small amount of the treatment carrier can be filled, and the treatment carrier can be easily replaced in this treatment tank. Furthermore, by adopting a valve opening and closing mechanism for discharging sludge from the water treatment tank, there is no inconvenience such as clogging of the pump as in the related art. Therefore, an embodiment will be described below, and the configuration of the present invention and the operation and effect thereof will be specifically described in more detail.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 of the accompanying drawings illustrates an example of a garbage processing apparatus according to the present invention as an outline of its configuration. For example, as illustrated in FIG. 1, the garbage disposal apparatus of the present invention is linked to a disposer (10) connected to a sink sink, and is provided with a garbage fermentation decomposition tank (1) and a water treatment tank (2). And a sludge treatment tank (3).

A stirring blade (11) is provided in the fermentation decomposition tank (1).
Is arranged to be rotated by a motor device (12), and a perforated plate (13) made of punched metal or the like is provided at the bottom thereof. And this fermentation decomposition tank (1)
Is charged with a processing carrier such as wood powder supporting microorganisms for fermentation and decomposition of garbage. Of course, the stirring blade (1
Appropriate stirring means may be used instead of 1), and ventilation means and the like may be considered as appropriate.

In the water treatment tank (2), a sedimentation tank (21) for storing sludge and a diffuser pipe (22) for aeration treatment are provided at its lower part. In the example of FIG. 1, the settling tank (21) is provided with a valve (23) for discharging the sludge. And further, in the sludge treatment tank (3),
A treatment carrier for fermenting and decomposing the sludge (31) is charged. Further, in this sludge treatment tank (3), a stirrer or a ventilation device for promoting fermentation decomposition can be appropriately arranged.

More specifically, for example, the fermentation decomposition tank (1) has a capacity of about 30 to 50 l, the water treatment tank (2) has a capacity of about 30 to 50 l, and the sludge treatment tank (3).
Is considered to be about 10 to 20 l. Of course, it is not limited to this. In the garbage processing apparatus of the present invention having the above configuration, the garbage solids and water discharged from the sink sink from home, restaurant, etc. are guided to the disposer (10), where the solids are finely crushed. And fed into the fermentation decomposition tank (1). Interlocking with the disposer (10) makes garbage disposal easier and more effective.

In the fermentation / decomposition tank (1), for the fermentation of microorganisms, the solid waste and water of the garbage are stirred together with the treated carrier and fermented / decomposed. The remaining water and fine decomposition residues are transferred from the perforated plate (13) to the water treatment tank (2). The decomposition residue does not accumulate in the decomposition fermenter (1), and there is almost no need to change the processing carrier. And the deterioration of the performance is small.

Further, deterioration of the treated carrier is suppressed and the particle size is kept constant, so that solid-liquid separation is facilitated. The water aerated in the water treatment tank (2) is drained to sewage, and the sludge (31) precipitates in the sedimentation tank (21). So, for example, every week to one month,
Open the valve (23) of the settling tank (21) and set the sludge (31).
And the like are discharged into the sludge treatment tank (3). Valve (2
In 3), there is no inconvenience such as a pump blockage as in the related art.

Next, in the sludge treatment tank (3), the sludge is fermented and decomposed by the treatment carrier. The treatment carrier in the sludge treatment tank (3) has a small load, can be used in a small amount, and can be easily replaced. It may be exchanged every six months to one year. Of course, the present invention is not limited to the above examples, and it goes without saying that garbage can be completely disassembled, and various details can be made in its detailed configuration.

[0021]

As is apparent from the embodiments of the present invention described in detail above, in the case of the present invention, the garbage can be completely decomposed and the following excellent effects can be obtained. . 1) Since no decomposition residue accumulates in the fermentation decomposition tank, there is almost no need to replace the processing carrier for fermentation decomposition, and there is little deterioration in its performance.

2) Since sludge and decomposition residues are not returned as in the prior art, the performance of the treated carrier in the fermentation / decomposition tank is prevented from being deteriorated due to accumulation of sludge and decomposition residues, and its deterioration is also suppressed. The particle size is kept constant, and the solid-liquid separation is facilitated. 3) Since the load on the sludge treatment tank is small, the amount of the treatment carrier used may be small, and the exchange of the treatment carrier is extremely easy as compared with the case of the fermentation decomposition tank.

4) Since the sediment in the water treatment tank is discharged by opening the valve, it is possible to suppress the occurrence of inconvenience due to troubles such as clogging such as a return means by a conventional pump.
