TECHNICAL FIELD The present invention relates to a garbage disposal apparatus that decomposes and eliminates garbage such as kitchen garbage generated from a general household, a restaurant industry such as a cafeteria and a restaurant, and a food manufacturing and processing industry by the action of microorganisms.

"Background technology"

Conventionally, when kitchen garbage and other garbage are decomposed and destroyed by the action of microorganisms, rotating wood is installed inside a wood chip that carries microorganisms that degrade and destroy garbage, such as cedar. Put the garbage to be treated into the treatment tank, put the garbage to be treated into the treatment tank, and rotate the rotating blades while applying hot air and moisture to agitate the garbage and wood chips to convert the garbage into dioxide. It had been decomposed into carbon gas and water vapor.

However, according to the conventional method, the garbage and the wood chips are stirred by the rotating blades in the treatment tank, so that the wood chips are severely worn, and the wood chips are finely ground due to the wear and the ability to carry microorganisms is reduced. I do. For this reason, it is necessary to frequently check the wear condition of the wood chips and replace the finely divided chips, and there has been a problem that the processing cost increases due to an increase in the number of working steps. Also, in order to increase the activity of microorganisms, warm air is blown into the treatment tank to raise the temperature of the wood chips.However, to prevent overheating of the wood chips and raise the temperature of the wood chips to the optimum temperature There was a problem in that heating for a long time was required, and the cost of heat energy required for heating the wood chips was high.

In addition, if the amount of food waste is increased, for example, when processing food waste of about 50 O kg, the force applied to the rotating blades increases, so a large driving force However, there is a problem in that power costs and equipment costs increase. In addition, since the conventional equipment is a batch-type device, the rotating blades are stopped, the lid of the treatment tank is opened, and garbage is charged, so that there is a problem that odor is generated when the garbage is charged. Furthermore, the inside of the treatment tank is evacuated to promote the decomposition and elimination of garbage by microorganisms and to suppress the generation of odor in the treatment tank, but the exhaust port is easily blocked by powder such as wood chips. The problem was that the exhaust efficiency decreased.

It is possible to prevent the chips from being finely ground due to the wear between the rotating blades and the chips. In order to promote both the activity of microorganisms that decompose garbage in the chips and the activity of microorganisms that extinguish the residues of microorganisms generated by the decomposition of garbage, and promote the decomposition and elimination of garbage, chips must be used. It is necessary to heat in 30 ~ 40. When heating chips, a cylindrical drum containing chips Instead of heating the inside, the stirring blades are heated, and the chips that are in direct contact with the stirring blades are heated by the heat transfer from the stirring blades. The amount of heat energy is reduced. Also, since only the power required to rotate the cylindrical drum supported by the bearings and the supporting wheels needs to be supplied, the power energy is also reduced.

When the temperature of the chip 12 exceeds 40 ° C, the heater 13 is turned off and the heating of the chip 12 is stopped.

The microorganisms in the chip 12 use the oxygen in the air to decompose garbage. At this time, carbon dioxide gas and water vapor are generated. For this reason, it is necessary to always supply fresh air into the cylindrical drum 15 and to release the generated carbon dioxide gas and water vapor outside the cylindrical drum 15. As shown in Fig. 1 and Fig. 5, fresh air is Supplied via one end of an o-ring joint 34 attached to the end of the protruding pipe 32. The other end of the rotary joint 34 is connected to an air supply pipe 35 whose end is sealed.

Next, the configuration of each part of the garbage supply means 11 will be described in detail. If there is a large size of garbage received for disposal, blockage may occur in the transport path when transported by the screw conveyor 44 or chips 12 in the cylindrical drum 15 may not be enough. Since it is not possible to contact the surface, the time required for the decomposition process becomes longer, which is a problem. For this reason, crushing by the crusher 43 before transport prevents clogging on the transport path and further enhances the mixing with the chips 12. Instead of the crusher 43, for example, a chopper can be used.

As shown in Fig. 1 and Fig. 2, the crushing part of the crusher 43 is attached, for example, by placing two rolls 43a with stainless steel spline grooves in parallel with the mouth axis parallel to each other. It has a structure. The rotation of the drive motor 49 is reduced via a reduction gear 50 attached to the output shaft of the drive motor 49. The two rolls 4 with spline grooves in the crusher 4 3 are machined. 3A is transmitted to. The two rolls 43a rotate in directions opposite to each other, and the input garbage is drawn between the two rolls 43a to be crushed and fragmented. At the lower part of the crusher 43, a discharge port 51 for discharging crushed garbage is provided.The discharge port 51 is connected to the garbage receiving port 53 provided on the transport pipe 52 of the screw conveyor 45 for discharge. Communicating.

In addition, the rotation support shaft 27 of the cylindrical drum 15 having a stepped hollow shape has a small-diameter portion 54 having a small diameter at one end 22 and a large diameter at the other end 23. It has a large-diameter portion 55, and the small-diameter portion 54 and the large-diameter portion 55 are connected at substantially the center of the cylindrical drum 15. The garbage receiving cylinder 46 of the cylindrical drum 15 is provided at the tip of the large diameter section 55 on the bearing 26 side. The large-diameter portion 55 also functions as a transport pipe for the charging screw conveyor 48, and a rotary shaft 56 for the charging screw conveyor 48 is provided in the large-diameter portion 55. I have.

The screw conveyor 4 4 is driven by a drive motor 57. The rotation of the drive motor 57 is transmitted to the rotation shaft 60 of the discharge screw conveyor 45 via a chain 59 through a reduction gear 58 attached to the output shaft of the drive motor 57. The rotating force of the rotating shaft 60 is transmitted to the rotating shaft 62 of the ascending screw conveyor 47 via the universal joint 61, and the rotating force of the rotating shaft 62 is transferred via the universal joint 63. And transmitted to the rotating shaft 56 of the screw conveyor 48. The rotary shaft 56 for the charging screw conveyor 48 is mounted so as to reach from the garbage receiving port 46 in the length direction of the cylindrical drum 15, for example, to a position advanced by about 1 Z 3. . In the portion of the large-diameter portion 55 where the rotary shaft 56 does not exist, the lower portion of the large-diameter portion 55 is cut out to form an opening 64, and the cylindrical screw drum 1 extends from the input screw conveyor 48. 5 Garbage input port And

Next, a method of processing garbage by the garbage processing apparatus 10 will be described. First, the principle of processing garbage using microorganisms is described.

A method of treating garbage to which the garbage disposal apparatus 10 according to one embodiment of the present invention is applied is a method of forming a chip 12 carrying microorganisms that decompose garbage and micro-micrococci that decompose and eliminate these residues. Maintain the temperature at 30 to 40 ° C, maintain the humidity in the cylindrical drum 15 containing the chips 12 at 60 to 90%, and put the crushed garbage into the cylindrical drum 15. By rotating the cylindrical drum 15, the garbage and the chips 12 are stirred, and the garbage is decomposed and eliminated by the action of microorganisms. Thus, during operation, the tip 12 is always maintained at a temperature at which the microorganisms are activated, and the inside of the cylindrical drum 15 is maintained at a humidity (preferably 65 to 85%) at which the microorganisms are activated. This makes it possible to continuously process garbage with little replacement of the chip 12 carrying the microorganism.

Microorganisms that decompose garbage include unicellular bacteria belonging to eubacteria, multicellular actinomycetes, and algae, protozoa, fungi, etc. belonging to eukaryotes. Sources include, for example, those capable of decomposing garbage and the like into carbon dioxide gas and water vapor while secreting enzymes. Enzymes secreted into and out of cells of microorganisms have the function of decomposing or synthesizing various substances, and play the role of biological catalyst. The main enzymes produced by microorganisms include human amylase, cellulase, maltase, perease, laccase, protease, and caratases.

It is preferable to use a wood chip (for example, a cedar chip) as the chip 12, but if it is a porous granular material capable of carrying microorganisms, it may be a synthetic wood chip. The present invention is applicable to the use of a fat material, an inorganic material, and other materials. Further

However, in the garbage processing method applied to the garbage processing apparatus 10 in the present embodiment, the micrococci are carried on the chip 12. Micrococci are bacteria that decompose and destroy dead bodies and residues of microorganisms. By carrying these bacteria on the chip 12, it is possible to prevent the generation of surplus (compost) such as processed food waste.

Next, a method of using the garbage disposal apparatus 10 will be described.

(1) Preparation operation

The lid 30 provided on the cylindrical drum 15 of the garbage disposal device 10 is opened, and a chip 12 carrying microorganisms for decomposing and eliminating garbage is put into the cylindrical drum 15. The amount of chips 12 to be introduced is about 100 liters per 100 kg of garbage. Microorganisms are more active in slightly humid conditions, so tip 12 is slightly moistened.

After closing the opening / closing lid 30, the rotary driving means 16 is driven to rotate the cylindrical drum 15 at a speed of, for example, one rotation Z 45 seconds while the heater 13 attached to the stirring blade 14 is turned on. The temperature of the chip 12 is set to 30 to 40 ° C. by energizing, and the humidity in the cylindrical drum 15 is set to 60 to 90%. When the temperature and humidity reach the predetermined conditions, the rotation of the cylindrical drum 15 is stopped.

(2) Garbage disposal

Put the garbage into the crusher 43 and crush it to a size that can mix well with the chips 12, for example, less than about 10 cm. A garbage detection sensor (not shown) that detects the presence of garbage is provided at the input of the crusher 43, so that the crusher 43 stops automatically when crushing of the garbage ends. Has become. The crushed garbage is transported to the center of the cylindrical drum 15 by the screw conveyor 44. Then, it falls into the cylindrical drum 15 from the opening 64. The opening 64, which is the exit of the screw conveyor 44, is provided with a fall detection sensor (not shown) that detects the fall of garbage, and drives the screw conveyor 44 when the transfer of garbage is completed. Is automatically stopped, and the cylindrical drum 15 is stopped, for example, by rotating it for 2 minutes. The fallen garbage is stirred together with the chips 12 in the cylindrical drum 15 to form a uniform mixed state. In addition, the timer is set so that the cylindrical drum 15 rotates intermittently, stopping at a rate of once every 30 minutes to 1 hour for 2 minutes and stopping independently of the introduction of garbage.

The microorganisms in the chip 12 use the oxygen in the air to decompose garbage. At this time, carbon dioxide gas and water vapor are generated. For this reason, it is necessary to always supply fresh air into the cylindrical drum 15 and to release the generated carbon dioxide gas and water vapor outside the cylindrical drum 15. Fresh air is sent from the blower fan 33a to the air supply pipe 35 provided in the cylindrical drum 15 via the mouth joint 334, and is opened to the air supply pipe 35 (not shown). It is supplied into the cylindrical drum 15 from the air supply port. The generated carbon dioxide gas and water vapor are sucked by an exhaust fan 39a from an exhaust port 37 provided at one end 22 of the cylindrical drum 15 and released into the air. Since the wire mesh 38 is attached to the exhaust port 37, the gas exhausted from the cylindrical drum 15 is discharged into the air in a clean state. The powders such as the chips 12 adhere to the wire mesh 38. The chips 1 2 attached to the wire mesh 38 by the stripping plate 42 provided on the rotating support shaft 27 in the cylindrical drum 15. Etc. are immediately removed. Therefore, stable exhaust can always be performed from the inside of the cylindrical drum 15, and odor generation in the cylindrical drum 15 can be prevented. Inside the cylindrical drum 15, a temperature sensor and a temperature controller (not shown) are attached for temperature control of the chip 12. If the temperature of the chip 12 is low, the activity of microorganisms is reduced. Therefore, when the temperature of the chip 12 becomes lower than 30 ° C, the heater 13 is energized to heat the chip 12, and the chip 12 is heated. When the temperature exceeds 40 ° C, the heater 13 is turned off and the heating of the chip 12 is stopped.

As described above, in the embodiment of the present invention, the cylindrical member 15 is connected to the rotary support shaft 27 provided at the axis of the cylindrical drum 15 by the bearings 25 and 26, and the heater 1 Power is supplied to the cylinder 3 via the slip ring 3 3, and air is blown to the cylindrical drum 15 and exhaust from the cylindrical drum 15 is performed via the rotary joints 34, 39. All the members attached to 15 rotate with the cylindrical drum 15 so that no large stress is generated on any particular member.

The embodiment of the present invention has been described above, but the present invention is not limited to this embodiment. For example, in this example, cedar wood chips were used as chips. However, if chips capable of carrying microorganisms capable of decomposing and eliminating garbage can be carried, for example, Nara, Hinoki, cherry blossoms, etc. Wood may be broken into pieces. Further, as a heating element for heating the chip, a thermoelectric element may be provided on the stirring blade instead of the heater, a heating medium may be circulated inside the stirring blade, or a method of combining the heating element and the heating medium may be used. . In order to supply fresh air into the cylindrical drum, one pipe provided with a number of air supply ports was used as the air supply pipe, but two or more pipes can be used. Further, in order to automatically adjust the humidity in the cylindrical drum, a humidity adjusting means having a humidity sensor, a humidity controller, and a moisture supplier may be provided. A wiping plate was provided to contact the rotating wire mesh to remove chips attached to the wire mesh, but a rod whose pendulum motion was induced by the rotation of the cylindrical drum was attached to the inner surface of the cylindrical drum at one end. The powder such as chips attached to the wire mesh may be wiped off by repeatedly sweeping the wire mesh. Further, although the rotary support shaft is provided as a method for supporting the cylindrical drum, a small-diameter portion of the rotary support shaft may be removed to provide a non-support shaft structure having only a large-diameter portion. In the case of an unsupported shaft structure, the end of the large-diameter portion can be made open so that the garbage conveyed by the input screw conveyor can be dropped directly from the opening of the large-diameter portion.

In addition, the screw conveyor that transports the garbage to the cylindrical drum has a screw screw conveyor for discharging, a screw conveyor for raising, and a screw conveyor for charging, but the crushed garbage by the crusher is used to raise the screw. It is also possible to adopt a configuration in which the conveyor belt is directly lifted to the garbage receiving port of the cylindrical drum by the U-conveyor, and is charged into the cylindrical drum by the screw-in conveyor for charging.
