Description

  The present invention relates to a garbage processing apparatus for reducing and reducing the volume of garbage generated in a kitchen of a home or a restaurant, and more particularly to a garbage processing apparatus of a system that decomposes garbage with a microbial carrier.

  A conventional garbage disposal apparatus of this type will be described with reference to FIG.

  The garbage disposal device mixes the microbial decomposition tank 2 containing the microbial carrier 1 such as sawdust and undegraded processed matter where the microorganisms (aerobic) live, and the input garbage 3 and the microbial carrier 1 Rotating stirrer 4 for stirring, driving device 5 for rotating the rotating stirrer 4, heating means 6 for maintaining a proper temperature in the microbial decomposition tank 2, and supplying oxygen (air) The ventilation fan 7 and the intake port 8 and control means (not shown) for controlling them are provided. The input garbage 3 is finally decomposed into carbon dioxide and water by microorganisms, and the garbage 3 is reduced. In addition, garbage disposal apparatuses that reduce the volume are generally known.

  Reference numeral 9 denotes a drying chamber provided in the upper part of the microbial decomposition tank 2 and partitioned by a rotatable plate 10, which is provided with an intake port 12 having an intake fan 11 and an exhaust port 14 having an exhaust fan 13.

  The operation of the garbage disposal apparatus configured as described above will be described.

  In a garbage processing apparatus that decomposes garbage 3 with microorganisms, it is necessary to create an environment for inhabiting and activating microorganisms. One of them requires a place where many microorganisms can inhabit and grow, and the microorganism carrier 1 is made of wood chips such as sawdust, porous plastic pieces or the like. Secondly, oxygen (air), which is a necessary condition for decomposition by microorganisms, is supplied to the microorganism carrier 1 by the stirring action of the rotating stirring bar 4. In addition, the three require moderate humidity. Microorganisms cannot survive in an excessively dry state, and conversely, in a state where there is a lot of moisture, the degradation ability is significantly reduced.

Therefore, when the garbage 3 is thrown into the drying chamber 9, air is supplied to the drying chamber 9 from the intake port 12 by the suction action of the intake fan 11, and the garbage 3 thrown into the drying chamber 9 is dried and exhausted. The air is exhausted from the exhaust port 14 by the exhaust action of the fan 13. When the plate 10 is rotated after the drying of the garbage 3, the dried garbage 3 falls into the microbial decomposition tank 2. Subsequently, the dropped garbage 3 is sufficiently mixed with the microbial carrier 1 by the stirring action of the rotating stirring bar 4 and microbial decomposition starts.

At that time, since the surface of the garbage 3 is dry, the entanglement between the garbage 3 itself or the garbage 3 and the microbial carrier 1 can be suppressed, and the size reduction of the garbage 3 and the microbial carrier 1 can be prevented. On the other hand, the control means adjusts the heating amount of the heating means 6 and the ventilation capacity of the ventilation fan 7 to keep the moisture of the microorganism carrier 1 constant. In particular, even when the garbage 3 with a lot of moisture is put into the drying chamber 9, the garbage 3 is dried to some extent in advance, so that the heating amount of the heating means 6 and the ventilation capacity of the ventilation fan 7 are increased by the control means. Thus, the moisture of the microorganism carrier 1 can be adjusted (see, for example, Patent Document 1).
JP-A-9-29211

  However, in the above-described conventional configuration, three pieces of the ventilation fan 7, the intake fan 11, and the exhaust fan 13 are necessary to dry the garbage 3, and the plate 10 and a mechanism for rotating the plate 10 are necessary. There is a problem that the structure becomes complicated and the main body itself becomes large.

  In order to simplify the structure, it is conceivable to eliminate the plate 10 and drop the garbage 3 directly on the microorganism carrier 1 and dry it. In that case, a fan is used to dry the garbage 3 with a lot of moisture. Increasing the amount of air blown causes the problem that the essential microorganism carrier 1 dries out and the activity of microorganisms becomes dull. In order to prevent this, if the amount of air blown is reduced, the water content of the garbage is infiltrated into the microbial carrier 1, resulting in excessive water content and slowing down the activity of the microorganisms.

  In the above case, it is necessary to control the air flow rate, but it has been extremely difficult to accurately detect the moisture content of garbage that does not satisfy certain conditions.

  The present invention solves the above-mentioned conventional problems, and by stably maintaining the drying performance of the garbage and the active state of the microorganisms, the garbage disposal apparatus can continue the decomposition performance of the garbage and has little odor. Is intended to provide.

In order to solve the above-described conventional problems, the garbage processing apparatus of the present invention includes a microbial decomposition unit that incorporates a microbial carrier and decomposes garbage with microorganisms, and is rotatably attached to the upper part of the microbial decomposition unit. A lid portion, a stirring means for stirring the microbial carrier and the garbage, an exhaust means for exhausting the air in the microbial decomposition processing section, an air blowing means for sucking outside air and blowing the garbage in the microbial decomposition processing section, Provided separately from the air flow path of the air blowing means, provided with a vent hole through which the microbial decomposition treatment part communicates with the outside air , operates the exhaust means and the air blowing means when the lid part is closed, and The amount of exhaust of the exhaust means is set to be larger than the amount of air blown to the garbage by the blower means. The amount of outside air is sucked and exhausted more efficiently than the amount of air blown to the input garbage. Odor is rare as it dries It smells to to discharge it is possible to realize a level which is not worried. Further, by taking in outside air from other vents other than the air blowing means, the exhaust dilution efficiency can be increased and the odor can be further reduced.

  The garbage disposal apparatus of the present invention is excellent in the ability to adjust the moisture content of the microbial carrier and can be used comfortably with very little odor.

According to a first aspect of the present invention, there is provided a microbial decomposition processing unit that contains a microbial carrier and decomposes garbage with microorganisms, a lid that is pivotally attached to the upper portion of the microbial decomposition processing unit, and a microbial carrier and garbage. The agitating means, the exhaust means for exhausting the air in the microbial decomposition processing section, the blowing means for sucking outside air and blowing to the garbage in the microbial decomposition processing section, and the blowing path of the blowing means are provided separately , A vent for communicating outside air with the microbial decomposition treatment unit, and when the lid is closed, the exhaust means and the blower means are operated, and the exhaust means makes the exhaust amount to the garbage The amount of air blown is set higher than the amount of air blown, and the amount of outside air that is blown to the input garbage is sucked and exhausted to efficiently dry the garbage and dilute and discharge the odor. Realize the level you don't care about It can be. Further, by taking in outside air from other vents other than the air blowing means, the exhaust dilution efficiency can be increased and the odor can be further reduced.

  In the second invention, in particular, the static pressure of the exhaust means of the first invention is set lower than the static pressure of the blower means. By slightly weakening the static pressure on the exhaust side, the blown air to the garbage is decomposed by microorganisms. Drying is performed more efficiently because it reaches the entire area.

  In the third invention, the exhaust means of the first or second invention is constituted by an air volume type fan such as an axial fan, and the air blowing means is constituted by a pressure type fan such as a centrifugal fan. The exhaust means and the air blowing means of the invention of 2 can be reduced in size, and an inexpensive garbage disposal machine can be provided.

  In the fourth aspect of the invention, in particular, the ventilation pressure loss of the blowing means of any one of the first to third aspects is made higher than the ventilation pressure loss of the exhaust means, and the static pressure of the exhaust means is higher than the ventilation pressure loss of the exhaust means. High and lower than the ventilation pressure loss of the air blowing means, and further the static pressure of the air blowing means is set higher than the air pressure loss of the air blowing means, and the exhaust air volume increases only when the air blowing means is activated. Moreover, extra air can be sucked in even during drying by blowing, and the exhaust can be diluted and discharged, so that the odor can be kept to a level that does not matter.

In particular, the fifth invention provides an air blowing port for blowing air from the air blowing means of any one of the first to fourth inventions into the microbial decomposition processing unit, and exhausts the microbial decomposition processing unit from the opening area of the air blowing port. Since the opening area of the exhaust port flowing into the means is set large, the setting of the ventilation pressure loss of each part in the fourth aspect of the invention can be easily configured, and an inexpensive and less odory garbage disposal machine can be provided .

According to a sixth aspect of the invention, in particular, the exhaust means of any one of the first to fifth aspects is formed by a suction fan disposed in a substantially cylindrical exhaust passage, and the center of the suction fan is the center of the exhaust passage. Since it is disposed at a position different from the center, moisture, dust, and dust discharged from the microbial decomposition tank do not directly hit the suction fan with respect to the exhaust means, and failure can be prevented.

In the seventh invention, in particular, the exhaust means of any one of the first to fifth inventions is formed by a suction fan disposed in a substantially cylindrical exhaust passage, and the suction fan is formed in the exhaust passage by 10 It is provided with an inclination in an angle range of 0 ° to 90 °, and even if water vapor or water droplets adhere to the suction fan, it can flow down naturally, thereby preventing a failure.

In an eighth aspect of the invention, in particular, the exhaust means according to any one of the first to seventh aspects includes a suction fan and a control device that controls the suction fan, and the control device is disposed upstream of the suction fan. As a result, water vapor and water droplets are less likely to adhere to a control device that is particularly susceptible to short circuit, and failure can be prevented.

Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the present invention is not limited to the embodiments.

(Embodiment 1)
The garbage processing apparatus in the 1st Embodiment of this invention is demonstrated using FIGS. 1-3.

  1 and 2 are cross-sectional views of the garbage disposal apparatus in the present embodiment, and FIG. 3 is a plan sectional view of the garbage disposal apparatus.

  In the figure, reference numeral 21 denotes a bottomed garbage storage container, which comprises a microbial decomposition treatment unit 22 for decomposing the garbage 26 and four rotating stirring bars 23 forming stirring means. Reference numeral 24 denotes a microbial carrier such as sawdust or undecomposed processed material that becomes a habitat of microorganisms. Reference numeral 25 denotes a drive device that rotationally drives the rotary stirring rod 23. Then, the rotating stirring rod 23 mixes and stirs the garbage 26 and the microbial carrier 24, and supplies oxygen (air) to the microbial carrier 24. Reference numeral 27 denotes a heating means including an electric heater for keeping the temperature in the microbial decomposition processing unit 22 properly.

  A lid 28 is pivotally attached to the upper part of the microbial decomposition processing unit 22 and opens and closes when the garbage 26 is put in. Reference numeral 29 denotes an exhaust port opened at the upper part of the side surface of the microbial decomposition processing unit 22 and is connected to an exhaust passage 51 having a built-in suction fan 30 serving as exhaust means. A plurality of discharge ports 56 are provided at the bottom of the blower-side main body of the suction fan 30. The suction fan 30 is an airflow type axial flow fan, and is disposed below the exhaust passage 51 so as to be shifted from the center of the exhaust passage 51 and is inclined at an angle of about 15 degrees.

  A control device 33 is built in the suction fan 30 and controls the suction fan 30, and is attached to the upstream side of the suction fan 30. Reference numeral 31 denotes a blower opening, which is a pressure type centrifugal fan and is connected to a blower passage 53 having a built-in drying fan 35 serving as a blower. Reference numeral 32 denotes a blow drying unit for drying the garbage 26 by blowing air.

  Further, the bottom surface of the lid 28 protrudes downward as shown in FIG. 1, and a part of the inclined portion 28 a formed thereby faces the air blowing port 31. The air blown from 31 is blown obliquely upward from the thrown-in garbage 26.

  Here, by making the opening area of the exhaust port 29 larger than the opening area of the blower port 31, the ventilation pressure loss of the drying fan 35 is made higher than the ventilation pressure loss of the suction fan 30 and the static pressure of the suction fan 30 is increased. Is set higher than the ventilation pressure loss of the blower port 31, and the static pressure of the drying fan 35 is set higher than the ventilation pressure loss of the blower port 31.

  Further, a processed product discharge port 41 for discharging processed products collected in the garbage storage container 21 is provided in front of the garbage storage container 21. A box-shaped processed product receiver 42 having an opening 42 a is attached at a position where the processed product discharge port 41 abuts, and the processed product overflowing from the garbage storage container 21 passes through the processed product discharge port 41 and is processed. It is intended to enter the receptacle 42.

  About the garbage processing machine comprised as mentioned above, the operation | movement and an effect | action are demonstrated below.

First, when a switch (not shown) is operated and the power is supplied, the suction fan 30 starts continuous operation, the outside air flows into the air passage 53, exits the air outlet 31, and blows air above the garbage storage container 21. It flows into the drying processing unit 32. Subsequently, the air is exhausted from the exhaust port 29 through the exhaust passage 51 through the exhaust port 56 by the exhausting action of the suction fan 30 and then to the outside. That is, the upper part of the garbage storage container 21 is constantly ventilated.

  Then, the lid 28 is opened, the garbage 26 is put into the microbial decomposition processing unit 22, and the lid 28 is closed again. Subsequently, when the drying fan 35 starts air blowing, the air hitting the lid 28 is rectified and ejected toward the garbage. The ejected air penetrates from the upper part to the lower part of the garbage 26 and, after colliding with the microorganism carrier 24, exits from the side of the garbage 26 and is exhausted from the exhaust port 29.

  At that time, since the air immediately carries out the water vapor generated from the garbage 26 (the steam partial pressure in the atmosphere of the garbage 26 is lowered), the garbage 26 is quickly dried. Furthermore, by making the opening area of the exhaust port 29 larger than the opening area of the air blowing port 31, the exhaust air flow rate of the suction fan 30 is made larger than the air flow rate of the drying fan 35, and the ventilation pressure loss of the drying fan 35 is reduced. The static pressure of the suction fan 30 is set higher than the vent pressure loss of the exhaust port 29 and lower than the vent pressure loss of the blower port 31, and the static pressure of the drying fan 35 is set higher than the vent pressure loss of the blower port 31. At the same time, since the outside air also enters the garbage processing container 21 from the treated product discharge port 41 that is not in direct communication with the drying fan 35, the exhaust gas can be diluted and discharged, so that the odor is not anxious. It can be kept to the standard. That is, the processed product discharge port 41 is a vent for taking in outside air different from the blower port 31.

  Note that, due to the exhausting action of the suction fan 30, the air ejected from the air blowing port 31 hardly flows backward from the packing 57 provided in the lid 28 and is almost exhausted from the exhaust port 56.

  Then, after the drying fan 35 starts blowing, a predetermined time has elapsed (for example, after 3 hours), and the operation of the drying fan 35 is stopped. Subsequently, the rotating stirring rod 23 is driven to rotate by the driving device 25, and the dried garbage 26 (for example, moisture is reduced by 10 to 50%) and the microorganism carrier 24 are mixed. On the other hand, the heating means 27 is ON / OFF controlled by a control device (not shown) so that the microbial carrier 24 of the microbial decomposition processing unit 22 maintains a predetermined temperature (for example, about 30 ° C.). Further, the rotary stirring rod 23 that is rotationally driven by the driving device 25 intermittently mixes and stirs the microbial carrier 24 and the dried garbage 26, and supplies oxygen (air) to the microbial carrier 24.

  At the same time, the stirring operation of the rotary stirring rod 23 releases the water vapor of the microorganism carrier 24 into the upper space of the garbage storage container 21. Furthermore, since the suction fan 30 exhausts water vapor, air, and the like in the garbage storage container 21 from the discharge port 56, the moisture of the microorganism carrier 24 can be adjusted (reduced moisture). Further, the suction fan 30 introduces outside air from the blower opening 31 to the garbage storage container 21. Next, the microorganisms that inhabit the microbial carrier 24 finally decompose the dried garbage 26 into carbon dioxide and water, and reduce and reduce the volume of the dried garbage 26.

  At this time, moisture, dust, and dust are discharged to the outside by the suction fan 30 through the exhaust passage 51. However, since the suction fan 30 is disposed at a position different from the center of the exhaust passage 51, Even if dirt or dust does not directly hit the suction fan 30, even if condensed water falls on the suction fan 30, the suction fan 30 is tilted and the control device 33 is arranged on the upstream side. Since water does not stay in the suction fan 30 or the control device 33 for a long time, a failure can be prevented.

Even when a large amount of garbage 26 or a lot of garbage 26 is put in, the air supplied from the drying fan 35 and ejected from the air blowing port 31 dries the garbage 26. Since the moisture content of the microbial carrier 24 can be adjusted by this dry matter, the microbial carrier 24 does not become particles or lumps, and air permeability can be ensured. That is, oxygen (air) can be efficiently supplied to the microorganism carrier 24 by intermittent mixing and stirring of the rotary stirring rod 23. In particular, since the air blown out from the air blowing port 31 permeates near the surface of the microorganism carrier 24 of the garbage storage container 21, the garbage storage container 21 can ensure good air permeability, and the dry garbage 26 with less smell can be secured. Decomposition performance can be continued.

  In addition, since the garbage 26 is dried by blowing air from the drying fan 35 using atmospheric heat without using a heat source by heating means (electric heater or burner) that consumes a large amount of energy in order to dry the garbage 26, energy saving can be achieved. .

  Furthermore, since the surface of the garbage 26 is dry, the decomposition of the garbage 26 is suppressed until the surface of the garbage 26 absorbs moisture from the microorganism carrier 24. As a result, the decomposition performance of the input garbage 26 is leveled, the generation peak of the odor component is reduced, and the instantaneous odor is reduced. Further, even when the amount of the microbial carrier 24 is small or the surface of the microbial carrier 24 is uneven, the air 26 always blown toward the bottom of the garbage storage container 21 is the garbage 26 put into the garbage storage container 21. The garbage 26 is dried while passing through the garbage 26. As a result, a stable drying performance of the garbage 26 is always obtained.

  As described above, in the present embodiment, the microbial decomposition processing unit 22 that incorporates the microbial carrier 24 and decomposes garbage with microorganisms, the stirring means 23 that agitates the microbial carrier 24 and garbage, and the microbial decomposition processing unit. The suction fan 30 that exhausts the air in 22 and the drying fan 35 that blows air into the microbial decomposition processing unit 22, and the exhaust air amount of the suction fan 30 is larger than the air blowing amount of the drying fan 35. The pressure is set lower than the static pressure of the drying fan 35, the ventilation pressure loss of the air outlet 31 is higher than the air pressure loss of the exhaust port 29, the static pressure of the suction fan 30 is higher than the air pressure loss of the exhaust port 29, and the air outlet 31. Since the static pressure of the drying fan 35 is set to be higher than the ventilation pressure loss of the blower port 31, in the normal exhaust state, the slight amount generated during the microbial decomposition process is set. By discharging the steam, the moisture of the microorganism carrier 24 is properly maintained, the activity of the microorganisms is maintained, and when the garbage is thrown in, the garbage is efficiently dried by the air blowing by the drying fan 35, and the smell is lost. As the microbial carrier 24 is discharged while being diluted, it is possible to prevent the microbial carrier 24 from becoming excessively watery and to maintain a level at which the odor does not matter.

  As described above, the garbage processing apparatus according to the present invention is excellent in the ability to adjust the moisture content of the microorganism carrier and can be maintained at a level that does not bother odors, so it is discharged from the cafeteria of homes, restaurants, and various facilities. The present invention can be widely applied to household and business use cocoon processing equipment for processing generated cocoons.
