This is a preferred curved shape.

The stirring blade of the present invention is suitable for a garbage disposal apparatus because it can efficiently perform mixing, stirring and pressure feeding while crushing an object to be stirred. Further, it can be used for mixing and stirring of powders and granules and high-viscosity products, and mixing and stirring involving a chemical reaction.

A dust processing apparatus using the stirring blade will be described with reference to FIG. FIG. 2 shows an example of a refuse treatment apparatus having two rotation axes and a gas-liquid separation device.
Is a cross-sectional view as viewed from the axial direction of the rotating shaft, and FIG.
It is sectional drawing. The processing container 3 includes a rectangular external housing 7,
A reaction tank 4 having rotating shafts 2 and 2 on which a plurality of stirring blades 1 are mounted, and a reaction tank 4
And a drive device such as a stirring motor 6 for rotating the rotating shaft 2. A garbage input lid 1 rotatably mounted on the upper part of the outer housing 7.
0a is provided so that the upper part of the garbage inlet 10 can be sealed. Further, it is preferable to cover the periphery of the outer housing 7 with a heat insulating material. The reaction tank 4 is composed of a stirring section 4a for mixing, stirring and pumping the garbage and the processed product at the bottom, and a circulation section 4b formed at the top.

The stirring section 4a is formed at the bottom of the reaction tank 4 with a semicylindrical bottom so that the stirring blade 1 can rotate. Two rotating shafts 2 and 2 are provided at substantially the center of the shaft. A plurality of stirring blades 1 are attached to the rotating shaft 2 at predetermined intervals. The stirring blade 1 is attached and fixed at a mounting angle of the blade front part 1 a perpendicular to the axial direction of the rotating shaft 2. The right angle includes an allowable angle range as long as the object to be stirred such as garbage can be crushed. Further, it is preferable that the blade front portion 1a is attached and fixed so that the surface thereof is perpendicular to the rotation shaft 2. By attaching the blade front part 1a at right angles to the axial direction and perpendicularly, a force is applied at right angles to the crushing direction, so that garbage and the like can be crushed most efficiently. The plurality of stirring blades 1 are located at positions where one semicircular blade is axially symmetric with respect to one rotation axis, and are fixed at substantially the same interval in the axial direction. The relative mounting positions of the stirring blades 1 on the two rotation shafts are set such that the stirring blades mounted on one rotation shaft are located between the stirring blades mounted on the other rotation shafts.

As shown in FIG. 2B, for example, as shown in FIG. 2B, the stirring blade 1 removes garbage and the processed material from one end 2a of the rotating shaft 2 toward the other end 2b (direction B in FIG. 2B). In addition to being mounted in the same direction so that it can be pumped,
At least one stirring blade 1 at the other end 2b of the rotating shaft.
i is attached to the rotating shaft 2 so that garbage and the processed product can be pressure-fed in the opposite direction. It is preferable that one stirring blade 1i is provided for one rotation axis. With one stirring blade installed in the opposite direction, the object to be stirred that has been fed in the direction B in FIG. 2B can be inverted.

In order to feed garbage and the like in a predetermined direction,
It is necessary to set the mounting state of the stirring blade 1 and the rotation direction of the rotating shaft 2. In the present invention, the blade front part 1a
Rotates the rotating shaft in a direction in which garbage and the like can be crushed. Further, by the rotation, the curved surface of the blade rear portion 1b is set in the direction in which the crushed garbage or the like advances in the direction in which the crushed garbage or the like is pressure-fed (the direction B shown in FIG. 2B). As a most preferred example, in the case of a garbage disposal apparatus having a parallel two-axis rotating shaft, as shown in FIG. 2A, the rotating directions of the rotating shafts 2 and 2 are outward (see FIG. 2). 2
The stirring blade 1 is attached and fixed so as to be in the directions (D, D shown in (a)). Therefore, two parallel rotation axes 2, 2
The plurality of agitating blades 1 respectively attached to the blades have blade front portions 1a attached in opposite directions. When rotating the two parallel shafts 2, 2 in the same direction, the blade front portions 1a are attached to each other in the same direction. Further, in the present invention, the rotation axis provided in the stirring section 4a is preferably a parallel two axis, but may be a single axis or three or more axes.

One stirring blade 1i is mounted in the opposite direction at the other end 2b of the rotating shaft on which the plurality of stirring blades are mounted. The stirring blade 1i is connected to the other end 2b of the rotating shaft.
The moving direction of the garbage and the like fed into the reactor is changed upward, so that the garbage and the like are automatically circulated in the reaction tank (direction C shown in FIG. 2B). This circulation becomes more efficient with the arrangement of the flaps 9.

The circulating portion 4b has a substantially cubic space through which garbage and the processed material can sufficiently circulate, and has a side wall surface 4c.
Are tilted inward from the vertical plane by a predetermined angle θ. The angle θ increases the heat of compression of the garbage and the processed product during the ascending circulation of the garbage and prevents the garbage from agglomerating during the descending, thereby making it possible to eliminate cavitation around the stirring blade 1 in the stirring section 4a. By setting the angle θ to 3 to 5 °, the garbage and the processed product are smoothly stirred and circulated. Further, a flap 9 which rises from one end of the rotating shaft and is curved is provided in the circulating portion 4b to assist circulation of garbage and the like. In addition, by forming the corner of the substantially cube in the reaction tank 4 with a curve having a predetermined radius of curvature, the garbage and the processed material can be more smoothly stirred and circulated.

At the upper part of the circulating portion 4b, there are provided ventilation holes 8 composed of an exhaust hole 8a and a dry air supply hole 8b, which communicate with the gas-liquid separation device 5, respectively. As the gas-liquid separator 5, any gas-liquid separator having a function of separating condensed water by cooling a gas containing high-temperature saturated steam can be used. For example, a radiator for a vehicle can be used. The garbage introduced into the reaction tank 4 is crushed, mixed, and pressure-fed in the stirring unit 4a, and is circulated again to the stirring unit 4a via the circulation unit 4b. During this process, the garbage undergoes a fermentation reaction and the composting proceeds. Due to the exothermic effect of this fermentation reaction, the moisture contained in the garbage is gasified. In addition, carbon dioxide and the like are also generated by the fermentation reaction.

The generated products such as moisture are led to the gas-liquid separator 5 through the exhaust port 8a to perform gas-liquid separation. Introduction of air containing saturated steam into the gas-liquid separation device 5 and reaction tank 4
The low-temperature dry air is resupplied to the dehumidifying motor 5a. The circulation of the cooling liquid in the gas-liquid separator 5 is performed by the cooling motor 5.
Perform by the operation of b. The separated water is stored in a predetermined container 5
c, and the cooled gas is returned to the reaction tank 4 again from the dry air supply hole 8b. The high-temperature gas containing saturated water vapor guided to the gas-liquid separation device 5 is cooled to a temperature lower than its dew point, so that the water is separated. Become. For this reason, by adjusting the operation of the dehumidifying motor 5a and the gas-liquid separation device 5, it is possible to adjust the water content and temperature of the garbage and the processed product thereof, and the humidity in the reaction tank, and the garbage fermentation reaction Can be optimized.

The garbage disposal apparatus of the present invention mainly turns on / off the stirring blades of the stirring section 4 a provided in the lower part of the reaction tank 4, the dehumidifying motor 5 a, and the cooling motor 5 b for controlling the temperature of the gas-liquid separator 5. The garbage thrown into the reaction tank can be processed by the control. Since a heating device for promoting fermentation provided in a conventional garbage fermentation device or the like is not required, energy saving can be achieved. In particular, by using the stirring blade of the present invention, crushing, mixing, and stirring can be performed efficiently, so that a fermentation reaction of garbage occurs in a short time. Further, since no external heating device is used, further energy saving can be achieved.

FIG. 3 shows the processing operation of the garbage processing apparatus of the present invention.
This will be described below. FIG. 3 is a block diagram of the garbage processing apparatus. The garbage processing apparatus includes a stirring motor 6 for crushing, mixing, pumping, and mixing garbage to maintain a fermentation reaction and a decomposition reaction, and a dehumidification motor 5a and a cooling motor 5b for operating the gas-liquid separation device 5. And Here, the dehumidifying motor 5a is a motor for operating an intake / exhaust pump for adjusting the amount of air flowing into and out of the ventilation hole 8, and the cooling motor 5b is for operating a pump for adjusting the amount of cooling water supplied to the gas-liquid separation device 5. It is a motor to make it. The stirring motor 6 is operated by a current supplied from a power supply 11 via an electromagnetic switch 12 to which a protection circuit 12a, a malfunction prevention circuit, a heating prevention circuit and an overcurrent prevention circuit 12b are connected. The operation of the stirring motor 6 is controlled by connecting the temperature sensor 15 and the operation time setting timer 14 to the electromagnetic switch 12 via the relay 16. This control is started and stopped by the start switch 13. The dehumidifying motor 5a is controlled in substantially the same manner as the stirring motor 6. Also,
The cooling motor 5b is directly controlled by the operation of the temperature sensor 15. By making such a block diagram, for example, the garbage with a water content of about 80% by weight
20 kg can be composted in about 6 hours by using a three-phase 200 V, 2.2 KW stirring motor 6.

A garbage disposal method using the garbage disposal apparatus of the present invention will be described. The garbage disposer has a reaction tank with a volume of about 200 liters, and has two parallel rotating shafts that rotate outward from each other at the bottom.
Five stirring blades are fixed at intervals, of which four are installed in the same direction and one at the shaft end is installed in the opposite direction. The maximum radius of the stirring blade is about 100 mm.

About 20 kg of garbage generated in a small-scale restaurant is input from the garbage input port 10. A predetermined amount of the processing residue which is composted the day before and contains a large amount of microorganisms together with the garbage is simultaneously charged. Instead of the processing residue, useful microorganisms such as bacteria, actinomycetes and filamentous fungi may be added. The agitation motor 6 starts operating by closing the garbage inlet 10 and turning on the power by turning on the start switch 13. The thrown garbage is mixed and pressure-fed toward the direction B in FIG. 2B by the curved portion at the rear of the blade while being crushed at the front of the blade of the stirring blade. The garbage fed to the other end is pushed upward by the action of the stirring blade 1i attached in the opposite direction and rises along the flap 9,
Circulation and stirring are performed in the reaction tank in the direction C in FIG. 2 (b).

The composting of garbage utilizes the fermentation action of microorganisms or the action of enzymes secreted by these microorganisms. Fermentation of temperature, moisture, humidity, oxygen amount, etc., which is an index of the calorific value in the reaction tank, is performed. It is necessary to adjust the reaction to proceed efficiently. In the present invention, the raw garbage and the microorganisms are sufficiently mixed by mixing and pumping the raw garbage that has been input while being crushed at the bottom of the reaction tank. Furthermore, the circulation is repeated while oxygen is supplied in contact with air at the upper portion of the reaction tank having a sufficient space, so that the fermentation reaction is easily caused. As a result, the fermentation reaction of garbage can be performed by stirring the stirring blade of the present invention.

In the above-mentioned processing method, the relationship between the operating state of the stirring motor 6, the dehumidifying motor 5a and the cooling motor 5c, the temperature of the object to be stirred such as garbage, and the amount of water collected in the gas-liquid separator 5 are shown in FIG. Shown in FIG. 4 shows an example in which composting is performed by operating the garbage disposal apparatus of the present invention. The horizontal axis indicates the reaction time, and the vertical axis indicates each parameter.
Also, the operation status of each motor is turned on (ON) and off (OF).
F).

The operation of the stirring motor 6 mixes and circulates objects to be stirred such as garbage in the reaction tank, and the temperature starts to rise. The motor power consumption of the stirring motor 6 measured by the current value shows a high value at the start of the reaction mainly due to the crushing of the material to be stirred, but gradually decreases from about one hour, and thereafter becomes substantially constant. In about 2 hours, the material to be stirred reaches about 75 ° C, the odor of garbage disappears, and it does not rot even if left to stand. For this reason, use secondary materials such as rice husks and sawdust,
Alternatively, if the intended use is taken into consideration, it can be used as compost in this state, and the composting can be completed in a very short time.

The fermentation reaction can be further promoted without the use of auxiliary materials, so as not to cause harm such as poor germination or poor growth on the plant. The fermentation reaction is performed by maintaining the temperature at which the fermentation can be maintained and at which the microorganisms do not die, for example, about 75 ° C., by turning on and off the stirring motor 6 and the dehumidifying motor 5a. The operation of the dehumidifying motor 5a can be automatically performed by the temperature sensor 15, the operation time setting timer 14, and the like. It may be operated manually. At the same time as or before the operation of the dehumidifying motor 5a, the cooling motor 5
The cooling water is supplied by automatically or manually turning c on or off. By the operation of the dehumidifying motor 5a, the gas in the reaction tank containing saturated steam at a temperature close to the fermentation reaction temperature is dehydrated through the gas-liquid separation device 5, and circulates in the reaction tank as cooled dry air. By turning on / off the operation of the stirring motor 6 and / or the dehumidifying motor 5a, the fermentation reaction temperature can be reduced.
The reaction is maintained at 60-90 ° C, preferably 70-80 ° C, and the humidity of the reactants at about 60% RH. By maintaining the fermentation conditions in this range, composting of garbage can be promoted without killing microorganisms. The measurement of temperature and humidity can be obtained by each sensor. Alternatively, the humidity is determined by the amount of water in the garbage input and the gas-liquid separation device 5.
And the amount of water separated in the above.

When the fermentation reaction proceeds and composting is completed, the garbage odor is completely eliminated, and the input garbage becomes granular or powdery compost. According to the method for treating garbage of the present invention, a) garbage can be taken out as compost, and b) the volume of compost produced by further promoting the fermentation and decomposition reactions can be achieved. B) When removing garbage as compost, use a dehumidifying motor 5
a and the cooling motor 5b are stopped, and the agitation motor 6 is operated intermittently, for example, once every 15 minutes within 30 seconds to lower the temperature of the compost to room temperature. Thereafter, the contents are taken out, the garbage disposal is completed, and compost is obtained. B) In order to further reduce the volume of the compost produced by further proceeding the reaction, the agitation motor 6 is operated intermittently to advance the compost secondary fermentation reaction so that the temperature of the compost can be maintained at 50 to 60 ° C. . As the fermentation progresses, the content decreases and almost disappears.

In the garbage processing method using the garbage processing apparatus of the present invention, composting can be performed by the action of a stirring motor, a cooling motor, and the like, so that a small size and energy saving can be achieved. Therefore, garbage generated during one day of business in small and medium-sized canteens, restaurants, restaurants, and the like can be processed on the same day. In addition, the use of the stirring blade of the present invention enables efficient stirring, so that the size of the reaction tank can be increased.
