It is composed.
[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0011]
FIG. 1 shows a schematic configuration of a garbage processing apparatus of the present invention.
[0012]
In FIG. 1, reference numeral 1 denotes a garbage input device, which is provided with a hopper 11 for inputting garbage and a disposer 12 for crushing the input garbage. The garbage crushed by the disposer 12 is supplied to an introduction pipe. Through 13, it is introduced into the decomposition tank 2 as a processing tank.
[0013]
The hopper 11 is formed at an input port 14 having an open upper surface, and the input port 14 is opened and closed by an opening / closing lid 15.
[0014]
The decomposition tank 2 is for decomposing garbage, and stores a decomposition liquid containing microorganisms for processing the garbage.
[0015]
Further, the decomposition tank 2 is provided with a stirrer 3, a circulation pump 4, and a diffusion member 5.
[0016]
In the stirrer 3, a stirring blade 33 provided on a rotating shaft 32 is rotatably provided by a rotation drive of a motor 31, and a flow for guiding a decomposition liquid stored in the decomposition tank 2 downward by rotation of the stirring blade 33 is provided. The solution is stirred so that the flow causes the entire decomposition solution to be homogeneous.
[0017]
The circulation pump 4 is disposed at the bottom of the decomposition tank 2 and is for sucking the decomposition liquid in the decomposition tank 2 and supplying it to the diffusion member 5. Are connected. The supply port 41a, which is the other end of the supply pipe 41, is disposed above the diffusion member 5, and the decomposition liquid is jetted from the supply port 41a to the diffusion member 5.
[0018]
The diffusion member 5 is for diffusing the decomposed liquid injected from the supply port 41a in the upper space, and supplies oxygen to the decomposed liquid by the diffusion to activate the activity of the microorganism. In other words, food waste is decomposed by aerobic microorganisms.
[0019]
Then, a downward flow of water generated by the stirrer 3 and a flow of water generated by suction of the circulating pump 4 generate a circulating flow in the decomposition liquid in the decomposition tank 2, and supply of the decomposition liquid to the liquid surface from the supply port 41 a. In conjunction with this, the whole decomposition solution is sufficiently stirred to homogenize. Thereby, the decomposition treatment of the decomposition liquid by the microorganism can be efficiently performed in a good state.
[0020]
On the other hand, the supply pipe 41 has a return pipe 42 branching from the middle thereof, and a part of the decomposition solution is supplied to the garbage through the return pipe 42 by opening and closing a valve 43 provided on the return pipe 42. It is returned to the input device 1.
[0021]
That is, by returning the decomposed liquid to the garbage input device 1 through the return pipe 42 and introducing the decomposed liquid into the decomposition tank 2, the garbage that has been input into the garbage input device 1 and crushed is decomposed together with the decomposed liquid through the introduction pipe 13. It is introduced into the tank 2.
[0022]
Further, a drying device 6 is connected to the decomposition tank 2. The drying device 6 is for periodically extracting and drying the residue and the like contained in the decomposition solution in the decomposition tank 2, and branching and connecting a branch tube 61 to the supply pipe 41. It is connected to the. The branch pipe 61 is provided with two open / close valves 61a and 61b, and a circulation pipe 61c connected to the decomposition tank 2 is connected between the open / close valves 61a and 61b.
[0023]
Usually, by opening the on-off valve 61a and closing the on-off valve 61b, a part of the decomposition solution is circulated to the decomposition tank 2 through the branch pipe 61 and the circulation pipe 61c. By closing the opening and closing valve 61a and opening the on-off valve 61b, the decomposed liquid accumulated during this time is introduced into the drying device 6.
[0024]
That is, instead of pulling out a large amount of the decomposition solution at once from the capacity side, the drying device 6 periodically pulls out an amount corresponding to the volume to perform the drying process. Is set so that the amount of the decomposition liquid accumulated in the branch pipe 61 during this period corresponds to this amount. As described above, a part of the decomposition solution is withdrawn and dried by the drying device 6 to adjust the salt concentration of the decomposition solution in the decomposition tank 2.
[0025]
The hot air that has contributed to the drying in the drying device 6 is guided to the upper space of the decomposition tank 2 through the hot air pipe 62. This hot air is used to maintain an appropriate temperature of about 40 ° C. at which the decomposition solution is activated, and in addition to the hot air, heat for decomposing microorganisms and heat for driving the circulation pump 4 are also used to maintain the temperature of the decomposition solution. Is contributing.
[0026]
Further, a water supply means (not shown) is provided in the decomposition tank 2, and the water level of the decomposition liquid is adjusted by appropriately supplying water into the decomposition tank 2 by the water supply means.
[0027]
Next, processing of garbage by the garbage processing apparatus configured as described above will be described.
[0028]
First, garbage generated in a kitchen or the like is opened into the hopper 11 through the opening 14 by opening the opening / closing lid 15 of the garbage input device 1, and crushed by the disposer 12. The crushed garbage is introduced into the decomposition tank 2 through the introduction pipe 13 together with the decomposition liquid introduced into the garbage input device 1 through the supply pipe 41 and the return pipe 42 by the circulation pump 4. That is, the introduced decomposition liquid plays a role of transporting the garbage from the garbage input device 1 to the decomposition tank 2.
[0029]
In the decomposition tank 2, the introduced garbage is decomposed by microorganisms in the decomposition liquid. At this time, the decomposition liquid is introduced into the supply port 41a through the supply pipe 41 by the circulation pump 4 and sprayed from the supply port 41a to the diffusion member 5 to supply oxygen to the decomposition liquid and to remove hot air from the drying device 6. The decomposition liquid is kept at an appropriate temperature by supplying. Further, a circulating flow is generated in the decomposed liquid by the stirring action of the stirrer 3 and the suction action of the decomposed liquid by the circulating pump 4, so that the decomposed liquid is sufficiently stirred to be homogeneous. As a result, the decomposition liquid is in a state where the activity of the microorganism is activated, and the decomposition treatment of garbage can be performed efficiently.
[0030]
On the other hand, in the drying device 6, residues of the decomposition solution and the like are periodically withdrawn according to the amount of garbage put into the decomposition tank 2, and the residue and the like dried by the drying device 6 are discharged to the outside from an outlet (not shown). Is discharged.
[0031]
By the way, the garbage processing apparatus for processing garbage in this way regulates the amount of garbage to be charged according to the processing scale of this apparatus (decomposing tank 2).
[0032]
Specifically, as shown in FIG. 2, a calculating unit 71 for calculating the amount of garbage put into the hopper 11 is provided, and the securing unit 72 is operated based on the calculation result of the calculating unit 71. A control means 73 is provided to secure the opening / closing lid 15 in a closed state.
[0033]
The calculating means 71 includes a detector 74 provided in the garbage dispenser 1 for detecting the opening and closing of the open / close lid 15 and a counter 75 for adding the number of open / close of the open / close lid 15 detected by the detector 74. The opening / closing number signal added by the counter 75 is input to the control means 73. In other words, when throwing garbage into the hopper 11, it is carried out using a container or the like, and the amount of each garbage is approximately the same. ing.
[0034]
As the detector 74, for example, a proximity sensor or a limit switch is used. Therefore, when the opening / closing lid 15 is opened and the detector 74 is turned off, and the opening / closing lid 15 is closed again and the detector 74 is turned on, the counter 75 counts. Is input to
[0035]
The control means 73 outputs an operation signal to the securing means 72 when the opening / closing number signal reaches a preset number of times set in accordance with the processing scale of the apparatus, and the securing means 72 closes the opening / closing lid 15. Secure with.
[0036]
As the securing means 72, for example, an electromagnetic lock device in which a securing pin 72a is made freely retractable is used. When the opening / closing lid 15 is closed, the securing pin 72a is provided at a base end of the opening / closing lid 15. The opening / closing lid 15 is secured in a closed state by protruding into a securing hole (not shown) of the secured securing piece 16.
[0037]
Further, the control means 73 outputs an operation signal to the securing means 72 as described above, and outputs an operation signal to the notification means 76 to operate the notification means 76.
[0038]
As the notification means 76, for example, a display device or the like is used in addition to an alarm lamp and an alarm buzzer, and as described above, when the opening / closing lid 15 is fixed, the lamp is turned on or blinking, an alarm sound, a display, etc. I'll let you know.
[0039]
The control means 73, the counter 75 and the notification means 76 are arranged in a control box 77 installed adjacent to the garbage dispenser 1, and are electrically connected to the securing means 72 and the detector 74. ing. The notification means 76 is provided facing the outer surface of the control box 77 so that an operator or the like can easily see it.
[0040]
When the opening / closing lid 15 is opened and closed a predetermined number of times, and the amount of garbage corresponding to the processing scale of the equipment is introduced into the decomposition tank 2, the locking means 72 secures the opening / closing lid 15 in a closed state. This will regulate the input of garbage. In this state, when a predetermined processing time elapses and the garbage can be decomposed by the decomposition tank 2, the locking of the opening / closing lid 15 by the locking means 72 is released and the counter 75 is reset. Then, the garbage processing as described above is performed again.
[0041]
As a result, the processing capacity in the decomposition tank 2 is reduced by introducing more garbage into the decomposition tank 2 than the processing scale, and the garbage is degraded by the large amount of garbage that is larger than the processing scale. Accidents such as spilling over from the surroundings and harming the surrounding environment due to dirt and odor can be prevented, and the garbage can be efficiently decomposed and treated under a favorable environment.
[0042]
Further, the garbage input device 1 and the decomposition tank 2 can be installed in places separated from each other by extending the introduction pipe 13 and the return pipe 42. Therefore, it is possible to install even a kitchen or the like where space is not sufficient if only the garbage input device 1 is used, and another device such as the disassembling tank 2 which requires a large installation space is installed in a place where space is available. Can be installed.
[0043]
For example, the garbage dispenser 1 is installed near the entrance opening to the kitchen of the building, and devices such as the decomposition tank 2 other than the garbage dispenser 1 are installed on the back side of the building where the installation space is relatively large. be able to.
[0044]
As a result, the restrictions on the installation of the garbage disposal device, which had been received from the viewpoint of the installation space, can be eased, and the garbage does not need to be turned around on the back side of the building. Can easily put in garbage.
[0045]
FIG. 3 shows another configuration of the calculating means.
[0046]
The calculating means 71 is provided in the garbage input device 1 and includes a detector 78 for detecting the amount of input garbage, and a counter 75 for adding the amount of garbage detected by the detector 78. The amount of garbage added by the counter 75 is input to the control means 73.
[0047]
As the detector 78, for example, a load cell provided below the disposer 12 is used. Therefore, every time the garbage is thrown in by opening the opening / closing lid 15, the throwing amount at that time is detected by the detector 78, and the throwing amount signal obtained by adding the throwing amount by the counter 75 is input to the control means 73. .
[0048]
The control means 73 outputs an operation signal to the securing means 72 and closes the opening / closing lid 15 by the securing means 72 when the total input signal reaches the preset dosage set in accordance with the processing scale of the apparatus. Secure in state.
[0049]
Note that the configurations of the securing means 72 and the notification means 76, and the operation control by these control means 73 are the same as those in the above-described embodiment, and the description is omitted.
[0050]
Thereby, similarly to the above, the reduction of the processing capacity in the decomposition tank 2 by introducing more garbage into the decomposition tank 2 than the processing scale, and a large amount of garbage larger than the processing scale are introduced. As a result, it is possible to prevent accidents such as garbage overflowing from the decomposition tank 2 to the surroundings and harming the surrounding environment due to dirt and odor, and it is possible to efficiently decompose garbage in a favorable environment. it can.
[0051]
FIG. 4 shows another example of the garbage processing apparatus of the present invention.
[0052]
This garbage processing apparatus is provided with a plurality of decomposition tanks 2a, 2b, and 2c as described above, and a middle part of an introduction pipe 13 connected to the disposer 12 of the garbage input apparatus 1 is provided with decomposition tanks 2a, 2b, and 2c. And the branched pipes 13a, 13b, 13c are communicated with the decomposition tanks 2a, 2b, 2c.
[0053]
Each branch pipe 13a, 13b, 13c is provided with an electromagnetic on-off valve 13d. The electromagnetic on-off valve 13d is set to a left position (see FIG. 4) in which the branch pipes 13a, 13b, 13c are shut off by a switching signal from the control means 73, and a right position in which the branch pipes 13a, 13b, 13c are opened. It is controlled to switch.
[0054]
In the case of the decomposition tanks 2a, 2b, and 2c, a part of the decomposition liquid is returned to the garbage input device 1 through the return pipe as described above, though not shown, and the decomposition liquid is formed together with the decomposition liquid. What is necessary is just to introduce garbage into the decomposition tanks 2a, 2b, and 2c from the refuse input apparatus 1.
[0055]
Therefore, first, only the solenoid on-off valve 13d of the branch pipe 13a connected to the decomposition tank 2a is switched to the right position by the control means 73, and the garbage input device 1 is communicated with the decomposition tank 2a through the introduction pipe 13 and the branch pipe 13a. . Thereby, the garbage thrown into the garbage throwing-in device 1 is introduced into the decomposition tank 2a and decomposed.
[0056]
In the case where the opening and closing of the opening / closing lid 15 is detected by the above-described detector 74 as shown in FIG. 4, the opening / closing lid 15 is opened and closed a predetermined number of times, and the amount of garbage corresponding to the processing scale of the decomposition tank 2a is reduced. When introduced into the decomposition tank 2a, the electromagnetic opening / closing valve 13d switched to the right position by the control means 73 is switched to the left position, and the communication between the decomposition tank 2a into which the garbage is introduced and the garbage charging device 1 is cut off.
[0057]
At the same time, the control means 73 switches only the solenoid on-off valve 13d of the branch pipe 13b connected to the decomposition tank 2b to the right position and resets the counter 75. Thereby, the garbage input device 1 communicates with the decomposition tank 2b through the introduction pipe 13 and the branch pipe 13b, and the garbage input into the garbage input apparatus 1 is now decomposed in the decomposition tank 2b.
[0058]
When the opening / closing lid 15 is opened and closed a predetermined number of times and the amount of garbage corresponding to the processing scale of the decomposition tank 2b is introduced into the decomposition tank 2b, the electromagnetic opening / closing valve 13d switched to the right position by the control means 73 is activated. The position is switched to the left position, and the communication between the decomposition tank 2b into which the garbage is introduced and the garbage charging device 1 is cut off.
[0059]
At the same time, the control means 73 switches only the electromagnetic opening / closing valve 13d of the branch pipe 13c connected to the decomposition tank 2c to the right position, resets the counter 75, and subsequently decomposes the garbage input into the garbage input device 1. It is introduced into the tank 2c to be decomposed.
[0060]
Then, when the opening / closing lid 15 is opened and closed a predetermined number of times and the amount of garbage corresponding to the processing scale of the decomposition tank 2c is introduced into the decomposition tank 2c, the electromagnetic opening / closing valve 13d switched to the right position by the control means 73 is activated. Switching to the left position, the communication between the decomposition tank 2c into which the garbage is introduced and the garbage charging device 1 is cut off, and the securing means 72 is operated by the control means 73 to secure the open / close lid 15 in a closed state. Regulate the input of garbage thereafter.
[0061]
In this manner, the plurality of decomposition tanks 2a, 2b, 2c are provided, and the garbage is sequentially introduced into the decomposition tanks 2a, 2b, 2c from the garbage input device 1 by the switching of the electromagnetic opening / closing valve 13d by the control means 73 to be decomposed. By processing, the processing amount of garbage can be significantly increased. In addition, the control of the control means 73 based on the calculation means 71 introduces a larger amount of garbage into the decomposition tanks 2a, 2b, 2c than the processing amount, thereby reducing the processing capacity of the decomposition tanks 2a, 2b, 2c. In addition, it is possible to prevent an accident such that garbage or the like overflows from each of the decomposition tanks 2a, 2b, and 2c to the surroundings due to a large amount of garbage that exceeds the processing amount and damages the surrounding environment due to dirt and odor. .
[0062]
In addition, as described above, when the garbage is sequentially introduced into each of the decomposition tanks 2a, 2b, and 2c and a predetermined amount of garbage is introduced into the last decomposition tank 2c, the garbage is first introduced into the decomposition tank 2a. If the garbage decomposition process is completed, the control means 73 can continuously introduce the garbage into the decomposition tank 2a without securing the open / close lid 15 in the closed state. That is, since the decomposition time of the garbage in each of the decomposition tanks 2a, 2b, and 2c can be grasped in advance based on the scale, the control means 73 completes the introduction of the garbage into each of the decomposition tanks 2a, 2b, and 2c. By measuring the time taken, it becomes possible to continuously perform the decomposition processing of the garbage by the decomposition tanks 2a, 2b, and 2c.
[0063]
Note that the above-described embodiment merely shows a preferred embodiment of the present invention, and the present invention is not limited to this, and various design changes can be made within the scope.
[0064]
For example, in the present embodiment, a so-called underwater decomposition type treatment apparatus for treating garbage with microorganisms of a decomposition solution stored in the decomposition tank 2 has been described, but the treatment method for decomposing garbage is not limited thereto. Instead, for example, a processing device of a system for decomposing garbage by microorganisms in a processing tank and performing a composting process may be employed.
[0065]
Further, in the present embodiment, it has been described that both the securing means 72 and the notifying means 76 are operated, but either one of the securing means 72 and the notifying means 76 may be operated.
[0066]
【The invention's effect】
As described above, according to the garbage processing apparatus of the present invention, based on the calculation result of the calculation means for calculating the amount of the input garbage, the notification means or the opening / closing lid is secured in a closed state. By providing a control means for operating the securing means or both, the introduction of more garbage into the processing tank than the processing scale causes a reduction in the processing capacity of the processing tank or a garbage larger than the processing scale. Injecting a large amount of garbage can prevent accidents such as garbage overflowing from the treatment tank and harming the surrounding environment due to dirt and odors. It can be disassembled.
