Description

  The present invention relates to a garbage disposal apparatus that decomposes and eliminates garbage generated from ordinary households, schools, factories, restaurants, hotels, etc. by the action of microorganisms, and is mainly suitable for business use. The present invention relates to a garbage disposal apparatus.

  Conventionally, as this kind of garbage processing apparatus, a fungus bed made of sawdust, wood chips, peat moss, palm peat, etc. containing microorganisms that decompose organic matter (for example, Bacillus soil fungi activated at high temperatures). An agitating blade is rotatably disposed inside a treatment tank that is accommodated and into which raw garbage is charged, and the raw garbage is decomposed to reduce its volume.

FIG. 7 shows an example of a conventional horizontal garbage processing apparatus. In the horizontal processing tank 101, a processing chamber 103 having a garbage input port 102 formed in the upper portion is provided. A rotation shaft 106 is rotatably provided so as to extend substantially horizontally from one side wall surface 104 to the other side wall surface 105, and the side wall surfaces 104, 105 are arranged around the rotation shaft 106 from the central portion of the processing chamber 103. A small-diameter spiral blade 107 that stirs and moves the garbage and the fungus bed 100 toward the side, and a large diameter that stirs and moves the garbage and the fungus bed 100 from the side wall surfaces 104 and 105 of the processing chamber 103 toward the center. A spiral blade 108 is attached, and by rotating the small-diameter spiral blade 107 and the large-diameter spiral blade 108, the garbage introduced into the processing chamber 103 from the garbage input port 102 is brought together with the fungus bed 100.

  However, in the conventional horizontal garbage processing apparatus as shown in FIG. 7, the small-diameter spiral blade 107 and the large-diameter spiral blade 108 attached to the rotating shaft 106 extending in the horizontal direction are rotated to dispose the garbage. Since it is agitated while being mixed with 100, not only does it require a large amount of power to drive, but the power consumption increases, a large-capacity motor is required, and the installation space is wide due to the horizontal type. It had a problem that it had to be taken.

  In order to solve these problems, recently, a garbage disposal device with a vertical cylindrical shape in the treatment tank has also been proposed. However, the volume, height, diameter, etc. of the fungus bed in the treatment tank are the amount of garbage input. In the current situation, there is no established index for quantitative determination in relation to

  In view of such circumstances, the present invention can quantitatively determine the volume, height, diameter, and the like of the fungus bed in a bowl-shaped cylindrical treatment tank in association with the amount of garbage input, and the power consumption In addition, an object of the present invention is to provide a garbage disposal device capable of efficiently decomposing and reducing the volume of garbage while reducing the installation space.

In the present invention, a stirring blade is rotatably disposed around a drive shaft extending in the vertical direction inside a vertical cylindrical processing tank in which a fungus bed containing microorganisms that decompose organic matter is stored and raw garbage is placed. However, in the garbage processing equipment that decomposes and reduces the volume of garbage,
The volume of the fungus bed is V _C = W / μ × K _C
However, V _C : Volume of fungus bed [l]
W: Daily garbage input [kg / day]
μ: Density of garbage [kg / l]
K _C : Bacteria bed coefficient (correction coefficient determined empirically for the volume of garbage)
The present invention relates to a garbage processing apparatus characterized by being set to a value calculated by the mathematical formula.

When configured as described above, in a garbage processing apparatus having a bowl-shaped cylindrical treatment tank, the volume V _C [l] of the fungus bed is quantitatively determined based on the amount of garbage input W [kg / day] per day. This makes it extremely effective for efficiently decomposing and reducing the volume of garbage while reducing power consumption and installation space.

In the above-mentioned garbage disposal apparatus, the density of garbage is μ≈0.5 [kg / l], the bacteria bed coefficient is K _C ≈6, and the bacteria bed volume is V _C ≈12 · W [l]. What can be obtained has been clarified by research of the present inventors, and this makes it possible to give the volume of the fungus bed as a more specific numerical value.

Further, in the garbage disposal apparatus, based on the volume V _C of the mushroom bed is calculated, so that the mushroom bed height is h ≦ 1 [m], determine the diameter of the fungal bed, the inner diameter of the processing tank If the inner diameter of the treatment tank is set in this way, the height of the fungus bed does not become h> 1 [m], and the microorganisms contained in the fungus bed can be prevented from being killed.

  On the other hand, in the garbage processing apparatus, a processing tank is installed inside a frame in which a bottom frame and an upper frame are connected by a plurality of support columns, and a stirring blade is disposed on the upper frame of the frame. It is possible to install a drive device for the drive shaft and a deodorization device that releases the exhaust gas containing malodorous substances generated inside the treatment tank and releases it to the outside. In this way, the treatment tank itself is not loaded. The driving device and the deodorizing device can be arranged above the processing tank so that the weight thereof is supported by the frame, and there is no fear that the installation space becomes wide.

  In addition, a garbage input port can be opened and closed at the top of the treatment tank, and an automatic input device is installed on the side of the frame to raise the bucket containing the garbage and input the garbage from the input port. Then, in a state where the bucket of the automatic charging device is lowered, after putting garbage into the bucket, the bucket in which the garbage is put is raised, the inlet of the processing tank is opened, and the garbage in the bucket is removed. It becomes possible to put into the treatment tank, and it becomes possible to automate a series of operations for throwing garbage.

  Furthermore, maintenance and the like can be easily performed by providing a maintenance inspection opening on the side surface of the treatment tank so that an operator can go in and out.

  Further, when the planar shape of the frame is a polygonal shape of a pentagon or more, the installation space can be further reduced as compared with a simple rectangular shape.

  According to the garbage processing apparatus according to claims 1 to 7 of the present invention, the volume, height, diameter, and the like of the fungus bed in the bowl-shaped cylindrical processing tank are quantitatively associated with the amount of garbage input. It is possible to determine the power consumption and the installation space, and it is possible to achieve an excellent effect that the garbage can be efficiently decomposed and reduced in volume.

  Next, the operation of the illustrated example will be described.

As described above, the volume of the bacterial bed 1 is V _C = W / μ × K _C
In the garbage processing apparatus in which the treatment tank 2 has a bowl-shaped cylindrical shape, the volume V of the fungus bed 1 based on the daily garbage input W [kg / day]. _C [l] can be determined quantitatively, which is extremely effective in efficiently decomposing and reducing the volume of garbage while reducing power consumption and installation space.

Further, in the garbage processing apparatus, the density of garbage is μ≈0.5 [kg / l], the bacteria bed coefficient is K _C ≈6, and the volume of the bacteria bed 1 is V _C ≈12 · W [ Since it has been found by the present inventors' research that it can be obtained as [1], this makes it possible to give the volume of the fungus bed 1 as a more specific numerical value.

When the height of the fungus bed 1 is h> 1 [m], the earth pressure at the bottom of the fungus bed increases due to its own weight, and the microorganisms contained in the fungus bed 1 may be killed. If the diameter of the fungus bed 1 is determined so that the height of the fungus bed 1 is h ≦ 1 [m] based on the volume V _C of the fungus bed 1 and the inner diameter of the treatment tank 2 is set, the fungus bed 1 H> 1 [m] is not satisfied, and the microorganisms contained in the fungus bed 1 are avoided from being killed.

Here, as a specific example, for example, when the input amount of garbage per day is W = 600 [kg / day],
The volume of fungus bed 1 is
V _C = W / μ × K _C
= 600 / 0.5 × 6
= 7200 [l]
= 7.2 [m ³ ]
Then, considering the fungus bed 1 as a cylinder with a diameter D,
^{_{V C = π · D 2/}} 4 × h
Than,
D = √ (4 · V _C / π / h)
= √ (4 × 7.2 / π / 1)
= 3.028 [m]
Therefore, the inner diameter of the treatment tank 2 may be set to 3.028 [m].

  On the other hand, in the case of this illustrated example, as shown in FIGS. 1 and 2, the treatment tank 2 is installed inside the frame 5 in which the bottom frame 5a and the upper frame 5b are connected by a plurality of columns 5c, and Installed on the upper frame 5b of the frame 5 are a drive device 6 for the drive shaft 3 of the stirring blade 4 and a deodorization device 7 for deodorizing and releasing the exhaust gas containing malodorous substances generated inside the treatment tank 2 to the outside. Therefore, the driving device 6 and the deodorizing device 7 can be arranged above the processing tank 2 so that the weight thereof is supported by the frame 5 without applying a load to the processing tank 2 itself. There is no need to worry about a large installation space.

  Further, as shown in FIG. 1 and FIG. 2, a garbage input port 8 is provided at the upper portion of the treatment tank 2 so as to be openable and closable, and a bucket 9 e containing garbage is placed on the side of the frame 5. Since the automatic charging device 9 that raises and throws the garbage from the charging port 8 is installed, after the bucket 9e of the automatic charging device 9 is lowered, the garbage 9e is put into the bucket 9e, The bucket 9e in which the garbage is put is raised, the inlet 8 of the processing tank 2 is opened, the garbage in the bucket 9e can be put into the processing tank 2, and a series of operations for putting the garbage is automated. Is possible.

  Further, as shown in FIGS. 2 and 6, the side surface of the treatment tank 2 is provided with a maintenance inspection opening 10 that can be opened and closed by an operator, so that airtightness is maintained during normal operation. However, if the open / close door 10a that is closed is opened, maintenance such as replacement of the bacteria bed 1 and inspection of the stirring blade 4 can be easily performed. Similarly to the maintenance inspection opening 10, if the opening / closing cover 11 a that is closed while maintaining airtightness is opened during normal operation, the inside of the processing tank 2 can be visually observed from the inspection window 11 as necessary. It is also easy to collect and check the processing status of garbage.

  Further, since the planar shape of the frame 5 is an octagon, the installation space can be made smaller than a simple quadrangular shape.

In this way, the volume V _C , height h, diameter D, etc. of the fungus bed 1 in the bowl-shaped cylindrical treatment tank 2 can be quantitatively determined in association with the raw garbage input amount W, While reducing the installation space, the garbage can be efficiently decomposed and reduced in volume.

  In addition, the garbage processing apparatus of the present invention is not limited to the above illustrated example, the number of stages of the stirring blade 4 is not limited to four stages, it may be one stage or a plurality of stages other than four stages, The deodorizing device 7 is not limited to two, but may be one group or a plurality of three or more groups. Furthermore, the planar shape of the frame 5 is not limited to an octagon but any polygonal shape as long as it is a pentagon or more. Of course, various modifications can be made without departing from the scope of the present invention.
