Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a garbage disposal apparatus that microbiologically decomposes garbage discharged from a general household or a restaurant.
[0002]
[Prior art]
Conventionally, raw garbage discharged from ordinary households and restaurants is pulverized by a disposer and processed to flow into sewage as it is together with water. This method is very convenient for the user without the need for maintenance. However, when the disposer is used, the water quality is significantly deteriorated by the crushed garbage. In other words, in places where sewage treatment plants are burdened or where sewage facilities are not fully equipped, water pollution will occur.
[0003]
In order to prevent such deterioration of water quality, an apparatus for decomposing microorganisms by mixing raw garbage with large sawdust has been developed.
[0004]
[Problems to be solved by the invention]
The structure in which the garbage is mixed with large sawdust to decompose microorganisms is prone to failure due to clogging of the pump for moving between the decomposition tanks due to the solid content of the decomposition product of garbage decomposed by microorganisms It has a problem.
[0005]
That is, if raw garbage composed of solid-liquid two-phase components is directly put into the apparatus, it takes a very long time for the microorganism treatment. This is because a group of microorganisms that ingest only the liquid component appears and proliferates ahead of other groups of microorganisms and becomes dominant, thereby suppressing the appearance of other groups of microorganisms. For this reason, it is necessary to separate and process the solid component and the liquid component using a plurality of decomposition tanks. Therefore, in order to perform such treatment, it is necessary to transfer waste water between a plurality of decomposition tanks. At this time, conventionally, the pump is easily clogged with the wastewater containing the solid component, which causes the failure.
[0006]
[Means for Solving the Problems]
In the present invention, when the raw garbage pulverized by the pulverization unit is microbially decomposed by a plurality of decomposition tanks, an ejector pump or a jet pump is circulated in the decomposition tank by a switching valve, or moved between the decomposition tanks, The garbage disposal apparatus is capable of disassembling garbage with no maintenance without clogging the pump.

【Example】
(Example 1)
The first embodiment of the present invention will be described below. FIG. 1 is an explanatory diagram showing the configuration of this embodiment. Reference numeral 2 denotes a crushing unit for crushing the garbage 1 together with water. In this embodiment, a disposer having a motor and a hammer cutter is used. The crushing unit 2 is provided directly connected to the drain of a kitchen sink. A switching valve 3 is provided at the lower part of the pulverizing unit 2. By switching the switching valve 3, the pulverized liquid of the garbage 1 pulverized by the pulverizing unit 2 is directly discharged into the sewage through the drain pipe 40, or is processed in the apparatus of this embodiment.
[0015]
A solid-liquid separator 4 is connected to the switching valve 3. The solid-liquid separation unit 4 includes a motor 4a, a conveying screw 5 connected to the motor 4a, and a mesh-like wire net 4b used as an outer shell. The solid-liquid separation unit 4 is arranged to pass through the first decomposition tank 7 and the second decomposition tank 8. The terminal portion of the solid-liquid separation unit 4 is a dissolution tank 6 disposed in the second decomposition tank 8. The melting tank 6 has an outer shell made of a mesh-like wire net. The first decomposition tank 7, the second decomposition tank 8, and the third decomposition tank 9 connected to the second decomposition tank 8 microbially decompose the crushed garbage. The first cracking tank 7, the second cracking tank 8 and the third cracking tank 9 are configured by dividing the inside of a drum-shaped filter bed 10 holding the filter bed into three rooms. . Further, the filter bed 10 is rotated by a drive unit including a motor (not shown). Each decomposition tank is provided with pumps 11, 12, 13, switching valves 14, 15, 16, sprinklers 17, 18, 19, and water tanks 20, 21, 22.
[0016]
The pump 11 has a function of circulating the processing solution of the garbage processed in the first decomposition tank 7 in the first decomposition tank 7 by the switching function of the switching valve 14 or moving it to the second decomposition tank 8. Yes. Similarly, the pump 12 has a function of circulating the processing solution of the garbage treated in the second decomposition tank 8 in the second decomposition tank 8 by the switching function of the switching valve 15 or moving it to the third decomposition tank 9. doing. Similarly, the pump 13 has a function of circulating the processing solution of the garbage treated by the third decomposition tank 9 in the third decomposition tank 9 by the switching function of the switching valve 16 or discharging it to the outside of the apparatus. . In the present embodiment, an ejector pump or a jet pump is used as the pumps 11, 12, and 13.
[0017]
FIG. 2 is a cross-sectional view showing the configuration of the first decomposition tank 7 or the second decomposition tank 8 or the third decomposition tank 9 and the configuration of the ejector pump according to this embodiment. The ejector pump 11 or 12 or 13 of the present embodiment includes a flow pipe 23 connected to the water tank 20 or 21 or 22, a centrifugal pump 24 disposed in the middle of the flow pipe 23, and a centrifugal type. A driving water tank 25 in which the pulverized liquid of the garbage 1 pumped up by the pump 24 is stored, and a centrifugal pump 27 connected to a suction port 26 provided at the bottom of the driving water tank 25; The nozzle 28 is connected to the discharge port of the centrifugal pump 27, and the suction path 31 in which the nozzle 28 is disposed. The suction path 31 is connected to a suction port 30 opened at the bottom of the water tank 20, 21, or 22. Further, since the pulverized liquid of the garbage 1 discharged from the centrifugal pump 27 becomes a jet jet ejected from the nozzle 28, the pulverized liquid of the garbage 1 sucked from the suction port 30 in the mixing part 29 is contained in the pulverized liquid. The solid component is sufficiently mixed with the liquid component. Thus, the pulverized liquid of the garbage 1 mixed in the mixing unit 29 is supplied to the water tank at the next stage, for example, the water tank 21 shown in FIG.
[0018]
The water tank 20, the water tank 21, and the water tank 22 are provided with a water level detection means 33 using, for example, a diaphragm type pressure sensor so as not to exceed the capacity.
[0019]
Next, the operation of the garbage disposal apparatus of this embodiment will be described. When the user puts garbage into an outlet disposed below the sink of the kitchen and presses a switch (not shown), the apparatus starts driving. That is, the damper in the switching valve 3 closes the drain port 40 side and opens the solid-liquid separation unit 4 side. At the same time, the crushing unit 2 starts to operate. The raw garbage thrown into the pulverizing unit 2 is finely pulverized with water by a hammer cutter. The crushed soot is moved in the solid-liquid separation unit 4 by the conveying screw 5 that rotates by receiving the rotation of the motor 4a constituting the solid-liquid separation unit 4. During this movement, the liquid component of the crushed soot is dropped into the first decomposition tank 7 through the metal mesh constituting the outline of the solid-liquid separator 4. Further, the solid component is conveyed to the dissolution tank 6 installed in the second decomposition tank 8.
[0020]
The first decomposition tank 7 mainly stores the liquid component of the crushed soot as described above. For this reason, a group of microorganisms that ingest soluble organic substances first appears, and this group of microorganisms dominates. Therefore, the liquid component of the soot stored in the first decomposition tank 7 is decomposed by the microorganism group. The second decomposition tank 8 mainly stores the solid components of the crushed soot. This solid component is mostly insoluble organic matter. Therefore, the second decomposition tank 8 is dominated by a group of microorganisms ingesting insoluble organic matter. Therefore, the solid component of the soot stored in the second decomposition tank 8 is decomposed by the microorganism group.
[0021]
In the present embodiment, the microbial decomposition in the first decomposition tank 7 is performed while internally circulating the liquid component of the soot stored by the pump 11 from about half a day to one day. That is, the setting of the switching valve 14 is set to the internal circulation side. The reason for this internal circulation is the liquid component of the soot stored in the water tank 20 constituting the first decomposition tank 7. By repeatedly contacting the filter bed 10, microbial degradation is promoted. That is, the above-mentioned microorganism group is propagated on the filter bed 10.
[0022]
That is, as described above, the pump 11 is driven by setting the switching valve 14 to the internal circulation side. As shown in FIG. 2, the pump 11 includes a flow pipe 23 and a centrifugal pump 24 provided in the middle of the flow pipe 23. When the centrifugal pump 24 is driven, the liquid component of the soot is sucked from the suction port 23a at the end of the flow pipe 23 and accumulates in the driving water tank 25. At this time, the fibrous solid component or the fine solid component stored in the bottom of the water tank 20 is located at a position where the suction port 23a is slightly away from the bottom surface of the water tank 20 in the first decomposition tank 7. Because it is not sucked. Thus, the liquid component of the soot stored in the water tank for driving water 25 is discharged through the nozzle 28 using the centrifugal pump 27. The nozzle 28 is provided in the suction path 31 connected to the suction port 30 at the bottom of the water tank 20. Due to the jet jet ejected by the nozzle 28, an ejector effect is generated in the mixing portion 29, which is a region in front of the nozzle 28, and negative pressure is generated. Due to this negative pressure, the liquid component and the solid component of the soot stored in the water tank 20 pass through the flow pipe 32 continuing from the suction path 31 to the suction path 31 as shown in FIG. 1 It is conveyed above the decomposition tank 7. Moreover, it contacts the filter floor part 10 through the water sprinkling part 17 from the upper direction of the 1st decomposition tank 7, and returns to the water tank 20 again. By repeating this internal circulation, the liquid component in the water tank 20 frequently comes into contact with the microbial group in the filter bed 10 and microbial decomposition proceeds.
[0023]
Thus, when the internal circulation for about half a day to 1 day is completed, the setting of the switching valve 14 is set to the transfer side to the second decomposition tank 8. For this reason, as a result of the pumping action of the ejector pump 11, the soot in the first cracking tank 7 that has passed through the suction passage 31 and the flow pipe 32 passes through the switching valve 14 from above the second cracking tank 8 to the filter bed. It passes through the part 10 and is dropped into the water tank 21. In the second decomposition tank 8, the solid component of the straw is decomposed by a group of microorganisms ingesting insoluble organic matter. At this time, the microbially decomposed liquid component is subjected to internal circulation similar to the internal circulation in the first decomposition tank 7. For this reason, the microbial decomposition of the solid component of the soot in the second decomposition tank 8 also proceeds efficiently. Further, when the internal circulation for about half a day to 1 day is completed, the setting of the switching valve 15 is set to the transfer side to the third decomposition tank 9. For this reason, as a result of the pump action of the ejector pump 12, the soot in the second cracking tank 8 that has passed through the suction passage 31 and the flow pipe 32 passes through the switching valve 14 from above the third cracking tank 8, and the filter bed portion. 10 is dropped into the water tank 22.
[0024]
The soot stored in the water tank 22 of the third decomposition tank 9 is a soot that has passed through the first decomposition tank 7 and the second decomposition tank 8. That is, it is the remaining soot that has been sufficiently microbially decomposed by the first decomposition tank 7 and the second decomposition tank 8. That is, most of the components that are difficult for microorganisms to ingest and decompose. Therefore, the microbial group that dominates in the third decomposition tank 9 can ingest hardly decomposable components. By performing the internal circulation performed in the first decomposition tank 7 and the second decomposition tank 8 by this group of microorganisms, the microorganism decomposition in the third decomposition tank 9 also proceeds. Thus, when the internal circulation for one day is completed from about half a day, the switching valve 16 is set to the drain outlet 41 side. For this reason, the soot stored in the water tank 22 is discharged out of the system from the drain port 73 by the pump action of the ejector pump 13.
[0025]
In the above description, a microbial membrane oxidation tank using a trickling filter is used, but there is no problem even if a microbial membrane oxidation tank such as an activated sludge tank or a rotating filter bed is used. .
[0026]
As described above, according to the present embodiment, by using the ejector pump or the jet pumps 11, 12, and 13, solid contents are not clogged in the pump, maintenance is not required, and garbage is efficiently decomposed. It is possible to realize a garbage disposal apparatus that can perform the above-described process.
Because of that.
[0027]
(Example 2)
Next, a second embodiment of the present invention will be described. FIG. 3 is a cross-sectional view showing a configuration of an ejector pump or a jet pump used in the garbage processing apparatus of this embodiment.
[0028]
In this embodiment, the soot discharged from the nozzle 34 is from the pump 70. The pump 70 sucks the liquid component of the soot stored in the water tank from the water absorption pipe 71 connected to the upper part of the water tank 7 or 8 or 9, and stores it in the water tank 53 for driving water from the drain pipe 72 It is. The liquid component of the soot stored in the driving water tank 53 is ejected as a jet jet from the nozzle 34 connected to the end of the drain pipe 55 by the centrifugal pump 54. For this reason, the mixing part 36 becomes a negative pressure by an ejector effect similarly to Example 1. FIG. Accordingly, the soot is sucked from the water tank 7, 8 or 9 from the flow pipe 37 generated by the mixing unit 36 and conveyed.
[0029]
At this time, in this embodiment, the nozzle 34 is configured to supply a jet jet from the outside of the flow pipe 37. For this reason, the nozzle 34 is less likely to be clogged as compared with the configuration described in the first embodiment. That is, when the nozzle 34 is disposed inside the flow pipe 37, the solid component of the soot sucked from the water tank may be entangled and clogged.
[0030]
As described above, according to the present embodiment, the ejector pump or the jet pump includes the nozzle 34 that ejects the jet flow from the outside, so that the pump is not clogged and the garbage is decomposed without maintenance. It is possible to realize a garbage disposal apparatus that can handle the above.
[0031]
(Example 3)
Next, a third embodiment of the present invention will be described. FIG. 4 is a cross-sectional view showing the configuration of an inflow pipe 38 constituting an ejector pump or a jet pump used in this embodiment. In this embodiment, a slit-like jet port 39 is annularly arranged on the outer wall of the flow pipe 38. Therefore, the jet flow ejected from the ejection port 39 is ejected in an annular shape to the mixing unit 40 shown in FIG. Therefore, the ejector effect generated is very large.
[0032]
As described above, according to the present embodiment, since the slit-like ejection port 39 is annularly arranged on the outer wall of the flow pipe 38, the generated ejector effect can be increased and the solid content is clogged. Therefore, the processing water can be sufficiently stirred, the microorganisms can be effectively decomposed, and a garbage processing apparatus that does not require maintenance is realized.
[0033]
(Example 4)
Next, a fourth embodiment of the present invention will be described. FIG. 5 is a cross-sectional view showing the configuration of the ejector pump or jet pump used in this embodiment. In this embodiment, a certain amount of tap water is used in the driving water tank 43. That is, a water level sensor 45 is provided in the driving water tank 43, and a predetermined amount of tap water is supplied in advance using a route not shown. Moreover, when the tap water stored here decreases, tap water is automatically supplied up to a predetermined amount.
[0034]
For this reason, the jet which the centrifugal pump 42 ejects from the nozzle 44 is tap water. That is, the jet blown out from the nozzle 44 contains almost no solid content. For this reason, the nozzle 44 is not clogged by the solid content, and a garbage disposal apparatus that does not require maintenance is realized.
[0035]
(Example 5)
Next, a fifth embodiment of the present invention will be described. FIG. 6 is a cross-sectional view showing the configuration of this embodiment. In this embodiment, a plurality of ejector pumps or jet pumps are used. That is, it has a centrifugal pump 51, a nozzle 47 connected to the centrifugal pump 51, a centrifugal pump 52, and a nozzle 48 connected to the centrifugal pump 52. For this reason, with respect to what uses a single pump and a single nozzle, a head can be earned and the load concerning a motor can be reduced. For this reason, the garbage processing apparatus which can be used for a long term and can decompose | disassemble garbage with no maintenance is realized.
[0036]
(Example 6)

In this embodiment, a stirring pipe 57 is provided in the water tank 20, the water tank 21, or the water tank 22. The stirring pipe 57 is constituted by a pipe, and stirs the crushed liquid stored in the water tank in the horizontal direction. In other words, the agitation pipe 57 has a suction port 58 and a blowout port 59 at the connection with the water tank. Further, the centrifugal pump 60 ejects the water sucked from the driving water tank 61 from the circulation nozzle 49 and the stirring nozzle 50 as a jet jet. The circulation nozzle 49 is connected to the flow pipe 54, and the stirring nozzle 50 is connected to the stirring path 57.
[0037]
The jet flow ejected by the stirring nozzle 50 sucks the crushed liquid stored in the water tank from the suction port 58 and blows it out from the blow port 59 to perform horizontal stirring using the circulation pipe 57. . At the same time, the circulation nozzle 49 ejects a jet jet in the vertical direction to the flow pipe 54, whereby the circulation in the microbial decomposition tank described in the above embodiments is performed. Moreover, the transfer to the microbial decomposition tank of the next stage is performed.
[0038]
As described above, according to the present embodiment, the decomposition tank feeds the agitation pipe 57 for agitating the treatment liquid for garbage in the decomposition tank and the treatment liquid for garbage in the decomposition tank to another decomposition tank. By having a flow pipe 55 and a configuration in which the stirring pipe 57 and the nozzles 49 and 50 for jetting water are provided in the flow pipe 54, the pulverized liquid of the soot in the decomposition tank is uniformly mixed, and the efficiency The present invention realizes a garbage disposal apparatus that can perform microbial decomposition well and can decompose garbage without maintenance.
[0039]

Next, a seventh embodiment of the present invention will be described. FIG. 8 is a cross-sectional view illustrating the configuration of this embodiment. In this embodiment, driving of the circulation nozzle 49 and driving of the stirring nozzle 50 are switched by the switching valve 65. The switching valve 65 is connected to the discharge port of the pump 60 and switches so that the water discharged from the discharge port of the pump 60 passes through either the circulation nozzle 49 or the stirring nozzle 50.
[0040]

When a predetermined time or time set in advance is reached, a control device (not shown) controls the switching valve 65 so as to open the path on the stirring nozzle 50 side and close the path on the circulation nozzle 49 side. Accordingly, the garbage pulverized liquid stored in the water tank 53 shown in FIG. 7 is subjected to circulation using the stirring pipe 57. When a predetermined time further elapses, the control device controls the switching valve 65 to open the path on the circulation nozzle 49 side and close the path on the stirring nozzle 50 side. Therefore, the crushed liquid of garbage stored in the water tank 53 is agitated using the flow pipe 54 and transferred to the water tank in the next stage.
