More specifically, the present invention relates to a garbage processing apparatus that decomposes garbage into moisture and carbon dioxide gas by mixing and stirring while supplying moisture and air to the garbage and microorganisms. The present invention relates to a waste disposal apparatus.

Garbage is always discharged along with human daily life and production activities. Conventionally, the amount of garbage generated from households and other food and beverage business operators is disposed of by incineration or landfill in a processing facility provided in an urban area. Recently, however, the amount of garbage has increased rapidly as living standards have improved and the economy has grown, and incineration and landfill disposal have increased fuel costs and labor costs for incineration, and landfill disposal sites have disappeared. It is difficult to process. For this reason, garbage processing apparatuses have been developed that can be decomposed into water and carbon dioxide gas using microorganisms and disposed of for disposal by ordinary households and other food service providers.

However, the garbage processing apparatus as described above has the following problems.
When a horizontal screw type stirring blade such as the garbage processing machine proposed in Patent Document 1 is used, the stirring efficiency of the garbage in the microorganism activation treatment tank is not necessarily high. When the horizontal axis is rotated and stirred, the garbage in the microorganism activation treatment tank is sent in the direction opposite to the stirring direction of the stirring blade and is pressed against the wall surface in the treatment tank. Therefore, there is a problem that the garbage is locally retained and the stirring efficiency of the garbage is lowered.
Moreover, in the vertical processing tank like the garbage processing apparatus proposed in Patent Document 2, the garbage is consolidated in the lower part, and uniform mixing of the garbage and the microorganisms is difficult, and stirring and mixing are not performed. Residual garbage may be generated. Furthermore, there are problems such as insufficient supply of air and moisture to the microorganisms, impairing the active environment of the microorganisms, and generation of odor because the garbage cannot be decomposed.
Furthermore, in a semicircular fermenter or processing tank such as the garbage processing machine proposed in Patent Document 3, when a large paddle is introduced, a large load is applied to the stirring blade, so that the energization of the stirring motor is stopped. There is. In this case, there is a problem that a separate work is required to remove the foreign matter caught on the stirring blade.

The present invention has been made in view of the above-mentioned problems, and its problem is to improve the mixing ability by stirring the microorganisms in the treatment tank and the garbage, etc., so that the decomposition treatment can be performed efficiently in a short time. It is to provide a waste disposal device. It is another object of the present invention to provide a garbage treatment apparatus having a treatment tank that facilitates air supply, water replenishment / drainage, and can smoothly rotate a stirring blade.

It is (c) side view which abbreviate | omitted one part of the exterior, the partition, etc. in order to show the structure of the garbage processing apparatus of this invention in three dimensions. It is a figure which shows the arrangement | positioning which the stirring blade used for the garbage processing apparatus of this invention has penetrated the rotating shaft. It is a figure which shows the other arrangement | positioning which the stirring blade used for the garbage processing apparatus of this invention has penetrated the rotating shaft.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1A is a front view, FIG. 1B is a plan view, and FIG. 1C is a side view of a garbage disposal apparatus according to the present invention.
The garbage processing apparatus 1 of this invention has the processing tank 2 which decomposes | disassembles garbage with microorganisms, and the waste_water | drain tank 3 which discharges | emits the water | moisture content generated in the processing tank 2. FIG.
The treatment tank 2 is formed of a cylindrical treatment tank main body 20 having a circular cross section on the lower side or a shape close thereto, and a horizontal axis-type rotation shaft 21 in which stirring blades 22 are dispersedly disposed inside. It is installed.
A water addition nozzle 24 is disposed on the upper part of the treatment tank 2.
The stirring blade 22 rotates inside the processing tank body 20 of the processing tank 2 to stir and mix the garbage and microorganisms. At this time, water is sprinkled from the water nozzle 24, thereby improving the mixing of garbage and microorganisms and assisting the activity of microorganisms.
The water used for the hydration nozzle 24 may be normal tap water. This hydration increases the activity of microorganisms and can dispose of garbage. Moreover, warm water can be used as a water | moisture content used for water addition. This is because the activity for annihilation treatment of microorganisms for garbage disposal is greatly influenced by temperature, and if there is a large difference between the temperature in the treatment tank 2 and the temperature of water to be added, the annihilation treatment rate becomes small. . By hydrating warm water, the activity of microorganisms can be further increased, and the rate of disposal of garbage can be increased.

The processing tank body 20 of the processing tank 2 can be simplified in structure by forming a cylindrical shape having a circular shape on the lower side or a shape close thereto. The shape close to a circle includes a shape such as an ellipse or a U-shape aligned vertically. By making the treatment tank body 20 of the treatment tank 2 into a circular shape or the like, smooth rotation can be obtained, so that the mixing property of garbage and microorganisms can be improved.
A hole for discharging water to be sprinkled and moisture generated by the action of microorganisms is provided on a part or the entire lower surface of the processing tank main body 20 in the processing tank 2. The hole may be circular or polygonal. Moreover, the whole or a part of the treatment tank main body 20 may be configured by a mesh, and further, a long and narrow gap may be provided in a slit shape. The shape of the hole is not particularly limited as long as it allows moisture to pass therethrough, and the size of the hole can be appropriately determined depending on the size of the treatment tank body 20 and the amount of garbage to be treated.

Agitation blades 22 are dispersedly arranged inside the processing tank 2.
The stirring blade 22 is disposed on a rotating shaft 21 provided in the processing tank 2, and the rotating shaft 21 is supported by bearings 26 at both ends of the garbage disposal apparatus 1. Further, the rotary shaft 21 drives a motor 25 provided below the garbage disposal apparatus 1 at a predetermined rotational speed by a sprocket 252 through a chain 251. At this time, the rotating shaft 21 is supported by the bearing 26 on the outer frame of the garbage disposal apparatus 1.
FIG. 2 is a view showing an arrangement in which stirring blades used in the garbage processing apparatus of the present invention pass through the rotation shaft.
Further, the tip end portion of the stirring blade 22 is inclined at an angle α with respect to the horizontal axis type rotating shaft 21 as shown in FIG. Thus, it is possible to prevent the food from being strongly hit against the garbage, and to efficiently and smoothly rotate and stir. Specifically, the angle α is inclined at 20 to 40 °, so that it can rotate smoothly and stir the garbage. Furthermore, the angle α is more preferably 30 °. It is possible to achieve both the mixing and stirring of garbage and microorganisms by the stirring blade 22 and the safety of preventing destruction by impact and the like.
Further, the stirring blade 22 has a trapezoidal or elliptical tip. Thereby, the stirring blade 22 can rotate smoothly inside the processing tank 2. In particular, it is preferable that the tip of the stirring blade 22 has a trapezoidal shape with an angle β. The angle β of the stirring blade 22 is set by the inner diameter of the treatment tank 2 of the garbage processing apparatus 1, so that efficient stirring is possible. Furthermore, it is possible to rotate without touching the treatment tank 2, to stir the garbage, and to rotate while pushing away from the portion spread at an angle β.

At this time, a part of the rotating shaft 21 is disposed so as to penetrate inside the horizontal shaft-type rotating shaft 21. Specifically, as shown in FIG. 2, the stirring blade shaft 34 set according to the size of the treatment tank 2 of the garbage processing apparatus 1 is made to penetrate the rotary shaft 21 so as to obtain a stable strength. It is fixed by welding at the welded portion 35.
Further, the reinforcing plates 23 and 23-1 of the stirring blade shaft 34 are welded. Another aim of the reinforcing plates 23 and 23-1 is to improve the stirring efficiency of the central portion of the processing tank 2 close to the rotating shaft 21 together with the tip of the stirring blade. The length of the reinforcing plate 23-1 parallel to the rotating shaft 21 is set to ½ of the stirring blade shaft 34. The length of the reinforcing plate 23 orthogonal to the rotating shaft 21 is set to a length of 50 to 80 mm from the rotating shaft 21 to the lower side of the stirring blade 22.

FIG. 3 is a view showing another arrangement in which the stirring blades used in the garbage processing apparatus of the present invention penetrate the rotating shaft.
Moreover, as shown in FIG. 3, you may arrange | position the stirring blade axis | shaft reinforcement material 23 like a square pyramid-shaped reinforcement pillar. Similarly, the stirring blade shaft 34 set according to the size of the treatment tank 2 of the garbage processing apparatus 1 is penetrated through the rotary shaft 21 and fixed by welding at a welding portion 35 so as to obtain a stable strength. . In this case, the reinforcing plate divided into two is fixed by welding.
Thus, even when there is a large amount of garbage in the treatment tank 2, the stirring blade 22 can be rotated without being damaged.

A drainage tank 3 for receiving drainage is provided under the treatment tank 2, and a drainage port 32 is provided at the end of the drainage tank body 30 of the drainage tank 3. The drainage tank body 30 of the drainage tank 3 has a cylindrical shape whose lower cross section is a triangle or a shape close thereto. By making it a triangular shape, drainage can be performed efficiently.
The drain port 32 can be communicated with the sewage port as it is. A water purifier may be provided between the drain port 32 and the sewage port.
Above the drainage tank 3, a cleaning pipe 31 for supplying cleaning water is disposed at the end opposite to the end where the drainage port 32 is located.
The inside of the garbage disposal apparatus 1 is in a temperature / humidity condition in which fungi and the like easily propagate. In particular, mold grows on the walls in the garbage treatment apparatus 1, the outer surface of the treatment tank 2, and the like and becomes the basis of odor. In order to clean this mold and other dirt, a cleaning pipe 31 is provided in the drainage tank 3 in the garbage disposal apparatus 1. The cleaning pipe 31 is disposed in the horizontal direction along the end of the drain tank 3. Moreover, it is provided in the edge part of the drainage tank 3 on the opposite side of the edge part with the drain port 32. FIG. The cleaning pipe 31 has a tubular structure and has a plurality of supply nozzles. The number and position of the supply nozzles of the cleaning pipe 31 are not particularly limited. Thereby, the whole drain tank main body 30 can be wash | cleaned uniformly.
Moreover, the bottom 33 of the drainage tank is inclined with respect to the end direction where the drainage port 32 is located with respect to the horizontal direction. By tilting and improving the flow of water, it is possible to drain the supplied water and water generated by the garbage treatment without stagnation. Furthermore, it is preferable that this inclination is 2 to 5 ° as an angle θ. The flow of water is improved by tilting at an angle θ of 2-5 °. Accordingly, suspended matter, oil phase, etc. can be discharged without stagnation. More preferably, the angle θ is 3 °. The drainage can be run without stagnation.

A heating device (not shown) is provided to adjust the temperature of the treatment tank 2 and the like. As the heating device, a ceramic heater and a heat reflecting plate for diffusing heat throughout the garbage processing device 1 are used. Examples of the heating device include a ceramic heater and an infrared heater, and these heaters are provided with a thermostat in order to stabilize the active environment of microorganisms regardless of the outside air temperature. At the same time, a heat reflecting plate is provided. In addition, a sensor for detecting temperature and humidity is attached to the vicinity of the processing tank 2.
Here, partition walls (not shown) are provided to seal both sides of the treatment tank 2 and the like. An operation panel for adjusting the rotational speed, temperature, and the like is attached between the partition wall and the side surface of the garbage disposal apparatus 1. Furthermore, a ventilation fan is provided to discharge the supplied air and the generated carbon dioxide. A filter for removing odor is attached to this ventilation fan.
Moreover, you may attach a caster to the lower part of this garbage processing apparatus 1. FIG. In such a garbage disposal apparatus 1, an opening / closing lid for placing microorganisms disposed in the treatment tank 2 and an openable / closable exterior opening / closing lid for placing garbage are disposed on the upper exterior plate.

The treatment tank 2 has a cylindrical shape with a diameter of 300 to 1400 mm, and preferably has a horizontal length of 400 to 3000 mm. If it is this magnitude | size, 2-300 kg can be thrown in as a garbage amount per day. The amount of microorganisms to be simultaneously added is usually 1/500 to 1/2000 of the amount of garbage.
Here, examples of the microorganism include aerobic bacteria such as Bacillus subtilis and Bacillus licheniformus, facultative anaerobes such as Lactobacillus acidophilus and Streptococcus lactis, and anaerobic bacteria such as Luminococcus albus and the like. You may use these individually or in mixture. Furthermore, it is only necessary to input the microorganism first by using a microorganism having a self-propagating function.
At the same time, the contact agent can be introduced as another substance. The contact agent is preferably one that adsorbs microorganisms and keeps it inside the apparatus, and does not decompose itself. Rice husk, sawdust, coconut shell chips, charcoal, zeolite and pearlite porous powder are used. As the contact agent, these can be mixed and used, and it is particularly preferable to use a mixture of rice husk and zeolite. In the case of charging, it is preferable to include the microorganism in the contact agent in advance. As the amount of the contact agent to be introduced, 20 to 50 times the weight of the microorganism and 5 to 30% with respect to the volume of the treatment tank 2 are appropriate.
Further, in the treatment tank 2, the internal garbage and microorganisms are uniformly mixed by rotating to enable contact with air and supply of moisture, and further, uniform contact between the garbage and the contact agent containing microorganisms. In order to achieve proper mixing and stirring, the rotational speed of the treatment tank 2 is controlled at a speed of about 1 to 4 revolutions per minute and an operation of about 3 to 10 minutes per hour.
If it rotates more than this, there will be a problem of dryness and waste littering. Conversely, if the rotation is too small, the supply of air and the like will be reduced, and anaerobic bacteria will increase, causing odor problems.

Water into the treatment tank 2 is sprinkled with tap water for about 30 seconds to 5 minutes simultaneously with the start of rotation from the water nozzle 24. In particular, it is preferable to spray water for about 1 to 3 minutes. Furthermore, it is desirable to spray water as appropriate to adjust the humidity with respect to long-time rotation. Moreover, as water to sprinkle, you may use the warm water whose temperature is the range of 30-50 degreeC.
Further, the temperature is uniformly diffused inside the garbage disposal device 1 by a heating device (not shown), and the internal temperature is kept constant. The internal temperature is preferably in the range of 15 to 40 ° C. Furthermore, it is preferable that it exists in the range of 25-30 degreeC.
These temperatures are detected by a sensor (not shown) provided inside the garbage disposal apparatus 1. Although the place to detect is not specifically limited, it is good to install so that the inside of the processing tank 2 may be caught exactly. At this time, a humidity sensor can be installed at the same time. The internal humidity is preferably in the range of 40 to 85 RH%. In particular, it is preferably in the range of 50 to 60 RH%. This is because the activity of microorganisms is greatly affected by temperature and humidity. The internal temperature and humidity are adjusted by watering from the heating device and the hydration nozzle 24.
