Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating organic waste, such as garbage, which can be rapidly and easily decomposed by high-temperature fermentation by microorganisms. TECHNICAL FIELD The present invention relates to an improvement of a processing apparatus capable of performing fermentation treatment and decomposition of sexual waste in a rotating drum and automatically discharging the treated product from the rotating drum.

[0002]

2. Description of the Related Art One of the methods for sanitary disposal of organic waste (hereinafter referred to as kitchen waste) such as garbage generated daily in kitchens of general households and restaurants is to use fermentation using microorganisms.
Decomposition methods are known. When processing garbage using the microorganism, a bed suitable for the activity of the microorganism (aerobic bacteria, a water regulator, a pH regulator, a nutrient, etc., may be appropriately blended,
This is further mixed and aged and provided) is put in a treatment tank in a fixed amount, and thereafter, kitchen waste is put into the treatment tank and mixed with the bacterial bed by a stirring means.

[0003] The garbage mixed with the fungal bed is decomposed into water and carbon dioxide gas by the activity of microorganisms and almost completely disappears. It is to be noted that the bacteria bed is exchanged every predetermined period (several times a year) from the treatment tank and replaced with a new bacteria bed. In addition, if necessary, a deficient bacterial bed may be appropriately supplemented.

[0004] Stirring means provided in the treatment tank for mixing kitchen garbage and a bacterial bed are roughly classified into a stirring blade type and a rotary drum type. The former is a method in which stirring blades are rotated in a fixed processing tank, and the latter is a rotating drum type processing tank whose rotation center axis (line) is parallel to the horizontal direction, and a rotation center axis (line). There is a rotary drum type processing tank inclined with respect to the horizontal direction.

[0005]

In each of the above systems,
In the former method in which the stirring blade is rotated in the fixed processing tank, the kitchen waste and the bacterial bed are stirred and mixed by the stirring blade.For example, when kitchen waste is put into the processing tank, the stirring blade is used. There is a problem in that garbage and the like are sandwiched between the tank and the tank wall, and the electric motor that drives the stirring blades is locked, and abnormal noise is generated.

Further, in the above case, although the garbage or the like that comes into contact with the stirring blade is stirred, it is difficult to uniformly stir and mix the garbage and the bacteria bed that do not come into contact with the stirring blade in the treatment tank. Stir and mix the kitchen garbage with the bacteria bed smoothly,
There has been a problem that it is difficult to satisfactorily decompose kitchen garbage by microorganisms in the fungus bed, and the crushing ability of input materials such as kitchen garbage is low.

On the other hand, in the latter rotating drum system, the rotating drum which rotates with the rotation center axis (line) positioned in the horizontal direction, the discharge port for discharging the garbage and the discharge port when the bacteria bed is replaced are natural. However, during the operation (during rotation) of the rotating drum, it is necessary to have a closed structure. In addition, when discharging the bacteria bed for charging the garbage and replacing the processed material including the residue of the garbage, If the rotary drum is not stopped at a predetermined position (for example, the upper surface) of the charging port or the like, the charging and discharging operations become troublesome. Therefore, there is a problem that a mechanism or the like for stopping the rotary drum at a correct position is required. There was a problem of increasing the manufacturing cost. Moreover,
After the dumping of kitchen garbage or the discharge of processed material, be sure to
Since a closing operation for securely closing the lid of the discharge port without error was required, the work of charging and discharging the garbage and the processed material was extremely troublesome and troublesome.

Further, in the case of a rotating drum in which the rotation center axis (line) rotates while being inclined with respect to the horizontal direction, the bacteria bed stays below the rotating drum, so that the mixing action with the garbage is smooth. It does not work well, it takes time to disassemble the garbage, and the processed material stays in the lower part of the rotating drum, creating an unnecessary dead space in the rotating drum, making it difficult to disassemble the garbage smoothly There was a problem.

In order to solve the above-mentioned problem, there is also a case where a stirring blade is provided in a drum during a stirring operation.
A large load is imposed by the load of the processed material staying on the stirring blade itself, and the stirring blade needs to be driven by an electric motor having a large driving force as in the case of the rotary drum. In addition, there is a problem that the manufacturing cost is unnecessarily high.

The present invention has been made in consideration of the above-described various problems, in that organic waste is uniformly fermented by microorganisms in a rotating drum, and the fermented / decomposed product is automatically discharged from the rotating drum. Another object of the present invention is to provide a rotating drum type organic waste treatment apparatus.

The other locking member 4a (right side in FIG. 1) which covers the opening b on the discharge side of the rotary drum 3 is used for automatic discharge of the processed foods as shown in FIG. A cylindrical discharge / inflow cylinder 28 for inflowing outside air is attached, and the discharge side opening b of the rotary drum 3 is formed in a rectangular shape so that it can be closed from the outside of the seal member 19a. I have. A part of the truncated cone of the rotary drum 3 provided with the opening b on the discharge side is provided with a microorganism for fermenting kitchen garbage and various base materials suitable for the inhabitation of the microorganism. An outlet for discharging the bacterial bed every few months (see Fig. 5)
The discharge port 29 is always closed by a discharge door 30 except when the bacteria bed is discharged.

Next, a fermentation process of kitchen garbage and a case where the fermented product is automatically discharged from the rotating drum 3 are mainly described with reference to FIGS.
Description will be made based on 0. First, a bacterial bed for fermenting kitchen waste is put into the rotating drum 3. This bed is, for example,
It is produced by mixing an appropriate amount of a seed bacterium (microorganism) composed of an aerobic fermentation bacterium and a water adjusting material such as sawdust. This bed is to be replenished to the rotating drum 3 as needed during the fermentation treatment / decomposition of the garbage, so it is preferable to prepare it in advance.

After the bacterial bed has been prepared, the opening / closing door 26 of the organic waste treatment apparatus A is opened as shown by a two-dot chain line in FIG. An appropriate amount of the bacterial bed is put into the rotating drum 3 through the opening a. An appropriate amount of the initial amount of the bacterial bed is about 1/3 of the volume of the rotating drum 3.

[0038] After introducing bacteria bed in the rotary drum 3, the rotary drum 3 by introducing the operation switch B ₁ controller 8
Is rotated, and the bacteria bed charged into the rotating drum 3 is
Rotating drum 3 while stirring with stirring blades 20 to 22 of
Spread on average. That is, the bacterial beds are evenly distributed in the rotating drum 3.

When the rotary drum 3 is rotated, the rotary drum 3 has support frames 24, 25 in which seal members 19, 19a attached to flange edges 17, 17a at both ends in the axial direction of the rotary drum 3 stand upright on the gantry 1. The rotating drum 3 is rotated by slidingly contacting the locking members 4 and 4a, so that the bacterial bed in the rotating drum 3 does not leak to the outside.

This is because the rotating drum 3 has the sealing member 19,
This is because the elastic member 19a is sandwiched between the locking members 4 and 4a so as to be able to rotate in a substantially airtight state by effectively utilizing the elasticity. For this reason, the rotation shafts 10 and 11 equipped with the rotating wheels 2 are rotated via the chain 16 by the activation of the electric motor 7,
The rotating drum 3 mounted on the rotating wheel 2 is
Make one revolution per minute. All of the commands for rotating the rotary drum 3 are issued by commands from the controller 8, and start the electric motor 7 to rotate the rotary drum 3 for a required time. After introducing the bacterial bed requirements rotary drum 3, stop the rotation of the rotary drum 3 once by operating the stop switch B _2.

Subsequently, kitchen garbage is put into the rotating drum 3 from an inlet (not shown) provided in the locking body 4. About 20% (20%) of the bacterial bed is appropriate for the input amount of kitchen waste. For this reason,
When a large amount of garbage is input at one time, it is necessary to prepare a bacterial bed according to the amount in advance. Closed door 26 After completing the insertion of garbage, again as shown in Step S ₁ of FIG. 8, turning on the operation switch B _1. With the introduction of the operation switch B _1, the motor 7 is activated by a command from the controller 8, thereby rotating the rotary drum 3 (FIG. 8
See step S ₂₎ of the.

[0042] Thereafter, it is checked whether the stop switch is pressed in step S _3, if not depressed, the process proceeds to step S _4, the predetermined time T1 (Rotary drum 3
Is one rotation, and in this embodiment, it is determined whether or not one minute has elapsed.

In the present embodiment, the rotating drum 3 is set in advance by the controller 8 so as to make one rotation / one minute as described above. Needless to say, when discharging the processed material, the controller 8 may be switched to a manual operation, for example, to rotate the rotary drum 3 a little earlier for a predetermined time.

[0044] When turned on after the drum 3 of the garbage is rotated 1, as shown in step S ₅ of FIG. 8, the rotary drum 3
Stop the rotation of.

The deodorizing means 6 is activated by a switch operation (not shown) at the time when the rotating drum 3 starts rotating or before that time, for example, when the bacterial bed is accommodated in the rotating drum 3. Discharge / inflow cylinder 2
Simultaneously with the inflow of the outside air from the inside 8, the air (bad odor) in the rotary drum 3 is forcibly sucked, introduced into the deodorizing means 6 through the connecting hose 5, and deodorized and exhausted (FIG. 10). Operation switch, electric motor, kitchen waste input, rotating drum, deodorizing device, stop switch).

When the rotating drum 3 starts rotating by the activation of the electric motor 7, the garbage and the bacteria bed are scraped up by the first to third stirring blades 20 to 22, and mixed by falling. In the initial stage of the rotation of the rotating drum 3, since the rotating drum 3 makes only one rotation, the mixing of the garbage and the bacterial bed is rough, but in the present embodiment, the rotating drum 3 is 3 to 4 hours (FIG. 8). because it is set in the show T2) every step S ₆ to rotate by one rotation, by a predetermined number of times rotation within the rotary drum 3 for several days, may be garbage and bacteria bed is stirred successively better .

When the garbage and the bacterial bed are mixed, the garbage is sequentially fermented and decomposed by vigorous activities of microorganisms living in the bacterial bed. As the fermentation process of kitchen garbage by this microorganism progresses, the base material in which the kitchen garbage and the bacterial bed are mixed rises to a temperature at which the activity of the microorganism is activated by the heat of fermentation,
Further, the fermentation treatment is promoted.

During the garbage fermentation treatment by the microorganisms, the deodorizing means 6 is constantly operated, and fresh outside air always flows into the inside of the rotary drum 3 from the discharge side opening b through the discharge / inflow cylinder 28. In addition to activating the activity of microorganisms, the microorganisms themselves are greatly proliferated, and the fermentation treatment and decomposition of garbage are favorably promoted. On the other hand, in the rotating drum 3,
The odor generated during the fermentation treatment is discharged to the outside of the rotary drum 3 through the connecting hose 5 by the deodorizing means 6, and is satisfactorily deodorized by a deodorizing member (not shown) such as activated carbon present in the deodorizing means 6. Exhausted.

Each time the rotating drum 3 rotates every predetermined time (3 to 4 hours), the processed material consisting of the kitchen waste and the bacteria bed in the rotating drum 3 is spirally moved toward the opening b on the discharge side of the rotating drum. By the first stirring blades 20 arranged in a shape,
It is transferred little by little to the opening b on the discharge side.

The processed material is transferred by the first stirring blade 20 to the opening b side by the second stirring blade 21 disposed in parallel with the axis of the rotary drum 2.
Alternatively, when falling from the gap existing between the first stirring blades 20, this is lifted to the upper side of the rotating drum 3,
After that, it is forcibly dropped to the lower side of the rotating drum 3 to understand that the processed material is agglomerated, to promote the agitation of the processed material satisfactorily, to increase the activity of microorganisms, and to carry out the fermentation process of garbage. Allow the disassembly to proceed smoothly.

Further, the third stirring blade 22 is disposed at a symmetrical angle with respect to the first stirring blade 20 as shown in FIGS. A part of the processed material sequentially transferred to the garbage is pushed back to the opening a on the input side, and the fermentation process in the garbage is promoted in the immature portion.

As described above, the garbage introduced into the rotating drum 3 is supplied to the three types of stirring blades 20 disposed on the rotating drum 3.
~ 22, not only is it stirred and mixed well with the bacterial bed, but also by the presence of the second and third stirring blades 21,22,
The garbage itself is finely crushed by suppressing clumping of the garbage and causing the part of the garbage to be transferred to the discharge side to be stirred and mixed again with the bacterial bed, thereby crushing the garbage itself. The fermentation treatment / decomposition by the garbage can be activated, and kitchen garbage can be treated efficiently.

Furthermore, the microorganisms that inhabit the bacterial bed are treated every time when the outside air flowing into the rotating drum 3 by the driving of the deodorizing means 6 is stirred, mixed and transferred by the rotation of the rotating drum 3. Activated and proliferated well by penetrating into the garbage, and most of the garbage becomes water (H ₂
O) and carbon dioxide (CO ₂ ).

This disassembling operation is performed while the rotating drum 3 is stopped until the next rotation. This is because even when the rotary drum 3 is stopped, the fermentation heat generated by the fermentation treatment of the microorganisms and the outside air are constantly flowing into the rotary drum 3 by the drive of the deodorizing means 6, so that the activity of the microorganisms is maintained. Can be performed well. Furthermore, by appropriately ventilating the decomposed water and carbon dioxide gas in the rotating drum 3,
By forcibly flowing into the deodorizing means 6 and subjecting it to clean deodorizing treatment and exhausting it to the atmosphere, kitchen waste is reduced.

The fermentation decomposition and treatment of the garbage are carried out by rotating the rotating drum 3 every several hours, and
The garbage and the germ bed are well stirred and mixed by 22 and the activity of the microorganisms inhabiting the germ bed is activated by the outside air constantly flowing into the discharge / inflow cylinder 28, and the garbage is fermented by the microorganism. After being treated, it is sequentially decomposed into water and carbon dioxide to reduce the weight.

On the other hand, the odor in the rotating drum 3 generated by the fermentation treatment is caused by the operation of the deodorizing means 6 to cause fresh outside air to flow into the rotating drum 3 and to discharge the fresh air at the same time. As it is configured to deodorize and exhaust, the harm caused by leakage of odor can be suppressed, and fresh oxygen is always supplied to the microorganisms by introducing outside air, and the fermentation heat is improved as the activity becomes active This makes it possible to effectively use the heat generated by natural fermentation to grow microorganisms without special preparation of heat-generating means that promotes the activity of microorganisms. It is possible to easily perform fermentation decomposition and treatment without using, and it is possible to manufacture an organic waste treatment apparatus with a simple configuration.

Then, the garbage is fermented and decomposed by microorganisms in the rotating drum 3 for a predetermined time, whereby
Most of the water is decomposed into water and carbon dioxide and can be discharged from the deodorizing means 6. However, after a lapse of a required time (about 3 weeks in the case of the present embodiment), a part of the kitchen garbage is converted into a finely powdered processed product, that is, a processed product (compost) mixed with a bacterial bed,
Due to the transfer action of the first stirring blades 20 sequentially, the rotary drum 3 is gradually discharged from the opening b on the discharge side through the discharge / inflow cylinder 28 every time the rotary drum 3 rotates, as shown in FIG. Then, it is stored little by little in a collection box 31 installed below the discharge / inflow cylinder 28.

In this example, as described above, after about three weeks have passed since the kitchen waste was first put into the rotating drum 3,
The example in which the treated material (compost) is discharged from the discharge / inflow cylinder 28 has been described. However, the present invention is not limited to this. The type of microorganisms inhabiting the bacterial bed, the mixing ratio between the bacterial bed and the kitchen garbage, the rotating drum 3 Arbitrarily change the volume of the garbage, the number of rotations of the rotating drum 3, etc., depending on the amount of the garbage to be processed and the degree of the contents, so that the processing is not necessarily performed in three weeks, and the processing is performed faster. Of course, it is good.

The garbage can be charged according to the amount of the bacterial bed contained in the rotating drum 3. The processing of the garbage proceeds, and the processed material is discharged from the discharge / inflow cylinder 28. When the time has been reached, the opening / closing door 26 may be opened at any time, and a proper amount of garbage to be processed may be charged and the processing may be continuously performed. Naturally, it is possible to replenish fresh bacterial beds little by little and to continuously perform fermentation and decomposition of kitchen garbage without stagnating.

Further, the opening / closing door 26 is opened when the kitchen waste is charged or the bacteria bed is replenished. However, since the odor in the rotary drum 3 is always suctioned by the deodorizing means 6, it is possible to prevent the odor from leaking out. It can be prevented well. In addition, the rotating drum 3 has a sealing member 1 attached to both ends in the axial direction.
Since the rotating members 9 and 19a are in close contact with the locking members 4 and 4a provided on the gantry 1 so as to be able to slide and rotate, odor is locked from the openings a and b during the rotation of the rotating drum 3. Body 4,
Leaking to the outside through a minute gap between
Since the sealing members 19 and 19a are removed by making close contact with the locking members 4 and 4a using the elastic force thereof,
Leakage of the odor can be prevented by simple means.

Next, when replacing the bacterial bed in the rotating drum 3 or cleaning the inside of the rotating drum 3,
When discharging the all processing of the rotary drum 3 (bacteria including floor) closes the inlet (not shown) together with (see step S ₇ of FIG. 9), the rotary drum shown in FIGS. 3 and 5 The discharge port 29 provided in the conical part inside the discharge side opening b of the third
Is opened.

According to the present invention, as described above, the present invention provides a fungus bed in which kitchen garbage and microorganisms for fermenting and decomposing the garbage are appropriately mixed by three types of stirring blades having different roles mounted in a rotating drum. The garbage is efficiently stirred and mixed, and the garbage is automatically transferred to the discharge port sequentially while being fermented and decomposed, and the processed product obtained by fermenting and decomposing the garbage from the discharge side of the rotating drum, that is, the bacterial bed Constructed so that the mixed processed material is automatically discharged, the kitchen waste can be satisfactorily fermented and decomposed by simply throwing it into the rotating drum from the input port each time it is generated, which is convenient. .

The rotary drum having the three types of stirring blades is formed in a hollow cylindrical shape, and is provided on the gantry side via seal members provided around the outer edges of the openings at both ends in the axial direction. Since the rotating drum is configured to be mounted on the rotating wheel while being rotatably slidably in contact with the pair of locking members, the rotating drum is opened in a hollow cylindrical shape, so that different types of stirring blades enter the inside thereof. Can be easily mounted, and the rotating drum itself can be easily mounted on and detached from the gantry, whereby washing and cleaning operations of the rotating drum can be easily performed.

Further, the seal members provided on both sides of the rotary drum are in sliding contact with the locking members provided on the frame, and
In addition to sealing the outside, a pair of locking bodies have an input port on one side, and a discharge / inflow cylinder on the other, so that when loading garbage into the rotating drum or rotating the processed material The discharge from the drum can be performed arbitrarily without stopping the rotating drum, so that operation management and maintenance of the processing apparatus can be easily performed.

In addition, a deodorizing means for deodorizing the odor generated during the fermentation processing of the garbage and for allowing the outside air to always flow into the rotating drum from the discharge / inflow cylinder is connected to the engaging body provided with the charging port via a connecting hose. It is convenient to handle because the odor can be satisfactorily controlled without dispersing the odor to the outside when throwing in the garbage and discharging the processed product after the fermentation decomposition and treatment. It is possible to provide a simple processing device.
