  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(Configuration of the embodiment)
FIG. 1 shows a perspective view of an organic-based workpiece decomposition processor according to an embodiment. The housing 20 of the organic-based object decomposition processing apparatus is configured of a lower housing 201 and an upper housing 202. On the upper surface of the upper housing 202, a substantially rectangular inlet 21 and a lid 10 for closing the inlet 21 are provided on a main surface 202a slightly inclined forward. The lid 10 can be opened and closed by the user holding the handle 11 with the hinge provided on the rear side as a rotation axis. FIG. 1 shows a state in which the lid 10 is opened. The opening and closing of the lid 10 may be other types such as a slide type, not a rotary type. The user can insert an organic material to be treated (hereinafter, simply referred to as garbage or a material to be treated) such as garbage into the inside through the opening 21 opened. In the inside of the insertion port 21, the blade | wing 23a of the stirring member 23 (stirring means) mentioned later is visible. The lid 10 is provided with an open / close support member 12 for maintaining the open state and the closed state. Although the open / close supporting member 12 uses a gas spring in the illustrated example, the present invention is not limited to this.

  FIG. 2 is a perspective view showing the lower housing 201 and the upper housing 202 shown in FIG. 1 separated vertically. In this example, the lower housing 201 has a slightly oblong box (rectangular parallelepiped) shape in which most of the upper surface is opened.

  The upper housing 202 has a lower end adapted to the upper end of the lower housing 201 and functions as a cover member placed on the upper end of the lower housing 201. The shape in which the main surface 202a having the lid 10 is slightly inclined to the front is for the convenience of the user who inputs the garbage.

  At the opening at the upper end of the lower housing 201, a slightly smaller frame body 203 having a shape similar to that of the upper housing 202 is placed. The frame body 203 has an opening 203a in which most of the area on the upper front side is opened, and has a horizontally long top plate 203b at the rear side. The water distribution pipe 36 extended from the bottom of the right rear portion of the lower housing 201 and guided upward is a water distribution pipe constituted by a flexible pipe or the like for supplying treated water to a treatment tank described later. The water distribution pipe 36 is bent at a substantially right angle above the lower housing 201 toward the lower side of the top plate 203 b and extends horizontally in the upper housing 202. The horizontal portion of the water distribution pipe 36 is provided with a plurality of water discharge ports 37, and the water discharge direction of the water discharge port 37 is directed to a substantially central region of the treatment tank. Further, from the opening 203 a of the frame body 203, a water distribution pipe (water discharge part) 35 annularly arranged in the vicinity of the inner wall of the processing tank of the lower housing 201 can be seen.

  From the water discharge port 37 of the water distribution pipe 36, shower-like water discharge (water sprinkling) is performed to the objects and microorganisms in the treatment tank. The shower-like water discharge (water sprinkling) has the purpose of supplying moisture to the object to be treated to promote decomposition of the object while dissolving carbon dioxide gas and ammonia gas generated at the time of decomposition into the treated water. In the present invention, purified treated water as described later is used for this shower-like water discharge.

  FIG. 3 is a schematic side view of the organic-based material decomposition processor shown in FIG. 1 from the right side thereof with the right side of the case removed. The arrangement state of the water distribution pipe 36 in FIG. 3 does not coincide with the arrangement state of the water distribution pipe 36 of FIG. There is no particular limitation on the position and form of the arrangement (routing) of the water distribution pipe 36 and the like, and it is optional as long as the function and operation thereof are not hindered.

  In the housing 20, a processing tank 22 as a first processing tank is disposed below the inlet 21. The treatment tank 22 contains an organic material to be treated containing moisture and an aerobic microorganism, decomposes the organic material to be treated into treated water containing at least organic matter, and drops the treated water generated by the decomposition treatment. It has many holes for the bottom. Although the volume of the processing tank 22 assumes about 400 L in this embodiment, it does not restrict to this volume. About 200 L of fungus bed material is introduced into the treatment tank 22 as an aerobic microorganism. The plurality of openings may be provided by forming the plurality of openings in the bottom of the bottomed processing tank 22, but in the present embodiment, the plurality of openings are formed in the open bottom of the processing tank 22. The configuration in which the perforated plate 25 is installed is adopted. By providing the processing tank 22 and the porous plate 25 which is a separate member, the preparation and maintenance of the opening can be facilitated.

  In the processing tank 22, as a stirring member 23 (stirring means) for stirring an object to be processed, a plurality of blades 23a rotating around a rotating shaft 24 extending substantially in the horizontal direction is provided. The rotary shaft 24 is rotationally driven by a drive source (for example, a motor) not shown. The processing tank 22 has a bottom surface curved so as to follow the lower half of the cylindrical region that includes the rotational trajectory of the tip of the blade 23a. Therefore, the porous plate 25 is curved as well.

  A water storage tank 27 as a second processing tank is disposed below the processing tank 22, that is, below the perforated plate 25. Although the volume of the water storage tank 27 assumes about 100 L in this embodiment, it does not restrict to this volume. The water storage tank 27 is a container for storing treated water obtained from the treatment tank 22 and decomposing organic substances contained in the treated water by aerobic microorganisms. In the water storage tank 27, as a drainage means, the drainage port 32 for forcibly discharging the treated water inside to the outside, and the treated water when the water surface 26 of the treated water exceeds a predetermined level as the overflow water outside And a drainage port 31 for draining the water.

  A third processing tank 41 is connected to and connected to the water storage tank 27 adjacent to the outside thereof. The treatment tank 41 is connected to a water supply means for taking the treated water therein and supplying it to the treatment tank 22. The water supply means is constituted by a pump 30 as a water pumping means disposed at the bottom of the lower housing 201 and a water distribution pipe 36 connected to the pump 30.

  The water distribution pipe 36 is for supplying treated water to the treatment tank 22, extends upward from the pump 30, bends almost at right angles and enters the inside of the treatment tank 22, and has the above-mentioned water outlet 37. It communicates with an annular water distribution pipe 35 (water discharge part) branched from the water pipe portion.

  The water distribution pipe 35 is disposed at least in the vicinity of the inner wall of the processing tank 22 above the rotation shaft 24 of the stirring member 23 and has a water outlet (not shown) for discharging treated water toward the inner wall of the processing tank 22. . The shape and position (height) of the water distribution pipe 35 and the position and number of the water discharge ports will be described in detail later.

  In addition, although it was set as the endless cyclic | annular water distribution pipe which connected the 360 degrees of water distribution pipes 35, the form of the end which the front-end closed may be sufficient. Alternatively, it may be in the form of an end which is bifurcated from the root.

  Between the water storage tank 27 and the processing tank 41, that is, at the inlet of the processing tank 41, a filter (filtering means) 33 in which a large number of openings are formed is disposed. The filtration means 33 constitutes treated water purification means for removing relatively large floating matter such as lipids solidified in the treatment tank 27 as impurities in treated water, and is constituted by, for example, a mesh-like member such as punching metal. can do. The size of the openings formed in the filtration means is preferably smaller than the openings in the bottom of the processing tank 22. Thereby, the to-be-processed object as a large sized impurity contained in the treated water to be pumped is removed, and problems such as clogging of the pump 30 and the water distribution pipe 36 are prevented.

  In the treatment tank 41, there is provided another treated water purification means for removing components such as carbon dioxide and ammonia contained in the treated water as other impurities in the treated water. The treated water purification means is, for example, a replaceable activated carbon cartridge or a distillation apparatus. In the present embodiment, since the fresh water supply means is not provided, the concentration of carbon dioxide, ammonia gas, and the like of the treated water becomes higher when the treatment is continued. An activated carbon cartridge, a distillation apparatus, etc. are for removing the said component.

  At the lower part in the water storage tank 27, a diffuser pipe 43 for supplying oxygen to the microorganisms in the water storage tank 27 is disposed along the longitudinal direction. The air diffuser 43 is provided with exhaust holes at a plurality of locations. A blower 68 as an air supply (aeration) means is installed outside the water storage tank 27, and the exhaust port is connected to one end of the air diffusion pipe 43. The air supply from the air diffusion pipe 43 by the blower 68 promotes the processing of the organic matter in the processing tank 27. The length, shape, and the like of the air diffusion tube 43 in the water storage tank 27 are not particularly limited.

  FIG. 4 is a schematic front view of the lower housing 201 from which the front part is removed. As shown in this figure, in the present embodiment, ten blades 23a are attached at approximately equal intervals in the longitudinal direction of the rotary shaft 24 so as to project radially outward from the rotary shaft 24. In this example, they project in four directions at an angle of 90 °. The bolt at the base of the blade 23a passes through the rotary shaft 24 and is fixed on the opposite side by a nut 23b. The shape, the number, the arrangement, the mounting structure, and the like of the blades 23a are merely examples, and the present invention is not limited to the illustrated ones.

  As shown in the partial enlarged view of the upper left part of FIG. 4, the water distribution pipe 35 is provided with a water outlet 35 a. Depending on the position (direction) of the water outlet 35a in the water distribution pipe, the direction of water discharge, for example, the discharge of treated water toward the inner wall of the treatment tank 22 is realized.

  FIG. 5 shows a configuration example of the water distribution pipe 35 disposed annularly in the vicinity of the inner wall of the processing tank 22 in accordance with the shape of the inner wall. Fig.5 (a)-(d) has shown the structural example from which the position and number of objects of a water discharge port differ. The approximate position of the water outlet and the direction of water discharge are indicated by arrows in the figure. The direction of the arrows distinguishes the water discharge (or watering) for the inner wall of the treatment tank and the organic waste between the outside and the inside.

  In the configuration example of FIG. 5A, a water discharge port for discharging water (or watering) in the outward direction (direction toward the inner wall of the treatment tank 22) is provided at regular intervals around the entire circumference of the annular water distribution pipe 35.

  In the configuration example of FIG. 5 (b), the number of water outlets (arrangement density) is changed depending on the area of the annular water distribution pipe 35. In this example, the arrangement density of the water discharge ports is changed by the rectangular annular side. For example, the arrangement density of the water outlet at the upper side of the figure (the rear side of the treatment tank 22) is increased. This reason corresponds to the case where the adhesion of the adherend is different depending on the area of the inner wall of the processing tank 22 as described later. There is a limit to the amount of treated water that is pumped up when trying to use treated water as effectively as possible while saving the amount of fresh water used. Therefore, in order to efficiently reuse such treated water, it is considered effective to change the arrangement density of the water discharge ports.

  5 (c) belongs to the case where the arrangement density of the water discharge ports is changed depending on the side as in FIG. 5 (b), but in this case, a specific side (in this case, it faces the side of the treatment tank 22) An example of a configuration in which the water outlet in side is eliminated is shown.

  FIG. 5D shows a configuration example in which the water distribution pipe 35 is provided with a water discharge port for discharging water (or watering) toward the inner direction instead of the direction toward the inner wall of the treatment tank 22. This is effective when supplementing the water released toward the object from the water outlet 37 of the water distribution pipe 36 as shown in FIG. That is, by providing a water discharge port for discharging water to the inside of the annular water distribution pipe 35, it is possible to supplement the water discharge (water sprinkling) by the water discharge port 37 for discharging water to the object in the treatment tank 22 and the microorganisms.

  In addition, although not shown, a form in which the features shown in FIGS. 5 (a) to 5 (d) are combined or other form may be employed.

  The control of each part such as the drive source (motor), the drainage means (electromagnetic valve), the pumping means, and the air supply means of the stirring means described above can be realized by a control unit described later.

(Operation of the embodiment)
At the time of use, the user opens the lid 10, inputs raw garbage from the inlet 21 together with the decomposition medium agent containing the microorganism, closes the lid 10, and turns on the power. After the power is turned on, the agitating member 23 rotates in a predetermined direction at a predetermined speed to agitate raw garbage. In the treatment tank 22, the raw garbage is decomposed by the action of microorganisms, and the treated water drops from the opening of the porous plate 25 into the water storage tank 27 and is accumulated in the water storage tank 27. The decomposition process continues in the water reservoir 27 as well. Organic waste, which is organic matter, is finally decomposed into water and carbon dioxide.

  Although treated water is not initially present in the water storage tank 27 and the treated water is not pumped and supplied to the treatment tank 22, the raw garbage usually contains water, so treatment is not carried out. There is no particular problem in the treatment in the tank 22. Moreover, you may supply water | moisture content with raw garbage from the inlet 21 as needed.

  Thereafter, the treated water generated by the treatment in the water storage tank 27 is filtered by the filter 33 which is a filtering means, and the filtered treated water is accumulated in the treatment tank 41. The filtered treated water is pumped by the pump 30 at a predetermined timing as described above, and is discharged from the water distribution pipe 35 into the treatment tank 22. That is, the treated water is discharged toward the object and the inner wall in the treatment tank 22. The treated water adhering to the inner wall can be washed away by the treated water discharged toward the inner wall. According to the test results of the applicant, it is possible that the object is likely to adhere to the inner wall in the region within the processing tank 22 on the side where the stirring member 23 rotating around the rotating shaft 24 extending substantially horizontally lifts up raw garbage. found. That is, when the stirring means for stirring the object in the treatment tank is provided, the material to be treated adheres to the inner wall of the treatment tank, in particular, to a position where the stirring blade in the treatment tank can not reach There is a problem of being left behind. Therefore, as described in FIG. 5, the water outlet of the water distribution pipe 35 is configured to discharge more treated water toward the region where at least the stirring member 23 rotates and passes upward on the inner wall of the treatment tank 22. It is also good.

  As described above, the treated water in the water storage tank 27 is drained to the outside as overflow water from the drainage port 31 when it exceeds a predetermined water level.

  Here, with reference to FIG. 6, an operation example regarding water supply and drainage etc. of the organic-based material decomposition processing apparatus will be described.

  FIGS. 6 (a) and 6 (b) show an example of a plurality of different timings of treatment such as water supply and drainage. The horizontal direction of the figure represents a time axis. As the main processing items to be executed, “treated water supply” to feed water to the treatment tank 22 by pumping with the pump 30, “stirring” to perform the stirring operation by the stirring member 23, discharging overflowed treated water or forced when necessary It is "drainage" which discharges treated water, and "air supply" which supplies air (gas containing at least oxygen) to treated water by an air supply means.

(Processing timing example 1)
At the timing shown in FIG. 6A, after the start of treatment, water is supplied (“treated water supply”) by treated water pumping for a predetermined amount (here, 15 to 20 L) for a predetermined time (here, 1 minute) to the treatment tank 22 At the same time, stirring is performed for a predetermined time (here, 3 minutes). However, if the treated water is not initially stored in the water storage tank 27 and the processing tank 41, there may be cases where effective pumping can not be performed. This treatment water supply is not only replenishment of water for promoting decomposition processing in the treatment tank 22 but also treatment at the same time as stirring operation to a part of the object to be treated adheres to the inner wall of the treatment tank during stirring. It also has the purpose of supplying water and washing away the object adhering to the inner wall of the treatment tank. For “Drainage”, the overflowed treated water is automatically drained. Forced drainage will be implemented as needed.

  Such processing is performed continuously or intermittently at predetermined time intervals. The "air supply" by the air supply means can always be performed during operation.

(Processing timing example 2)
At the timing shown in FIG. 6 (b), the processing water supply and stirring shown in FIG. 6 (a) are executed more frequently (in this example, twice). As for the “drainage”, the overflowed treated water is automatically drained off as in the processing timing example 1. Forced drainage will be implemented as needed.

  Such processing is performed continuously or intermittently at predetermined time intervals. The "air supply" by the air supply means can always be performed during operation.

  In the processing timing examples 1 and 2, the treatment water supply capacity differs depending on the capacity of the treatment tank 22, the capacity of the pump 30, the configuration of the water distribution pipes 36 and 35, etc. It is These times may be set variably by the user.

(Modification of the embodiment)
FIG. 7 shows a schematic side view of an organic-based workpiece decomposition processor according to a modification of the embodiment. The same components as those shown in FIG. 3 are denoted by the same reference numerals, and duplicate descriptions will be omitted. The difference from the configuration shown in FIG. 3 is the installation position (height) of the annular water distribution pipe 35 as the water discharger. The water distribution pipe 35 of FIG. 7 is installed at a lower position than that of FIG. As a result, when the water discharge port 37 is sufficient to discharge water to the object to be treated (water sprinkling), the treated water is discharged more directly toward the region on the inner wall of the treatment tank 22 where the object to be treated tends to adhere. Can focus on cleaning the inner wall.

(Example of configuration of processing device)
FIG. 8 is a block diagram showing an example of the configuration of a processing apparatus for performing control for realizing the processing timing of the organic-based object decomposition processor as described in FIG. The processing apparatus includes a power cable 51 with a power plug, a power switch (SW) 53, a power unit 55, a control unit 57, an input / output unit 59, an open / close sensor 61, a pump 63 (corresponding to the pump 30), and a stirring motor 65. , A solenoid valve 67 (drainage means), and a blower 68 (air supply means).

  The power switch 53 is a switch for turning on / off the power of the organic material decomposition processing apparatus. The control unit 57 is configured by a processing unit such as a processor for executing the above-described various processes of the organic-based material decomposition processing apparatus. The open / close sensor 61 is a means for detecting the open / close operation of the window portion 10. The detection principle may be any of optical, mechanical, electromagnetic, etc., and it does not matter in particular. The control unit 57 receives an input from the open / close sensor 61 or the like through the input / output unit 59, and outputs a control signal to the pump 63, the stirring motor 65, or the like. The control unit 57 also has a timer function for performing desired control when the set time has elapsed. The operation of the control unit 57 can be determined by a predetermined control program. For example, when the opening / closing sensor 61 detects that the lid 10 is open during operation of the organic material decomposition processing machine, for example, the control unit 57 temporarily stops the stirring motor 65 and other operations for safety And resume their operation when closure is detected. Further, the control unit 57 controls the pump 63, the stirring motor 65, the solenoid valve 67, and the blower 68 in accordance with the processing timing as described above.

(Other modifications)
As mentioned above, although preferred embodiment of this invention was described, it is possible to perform various deformation | transformation and changes other than having mentioned above.
