Details of the normal operation mode and the holiday operation mode will be described later with reference to flowcharts.
[0028]
Next, the operation of the embodiment of the present invention having the above configuration will be described.
[0029]
First, the inlet opening / closing doors 62 and 62 provided on the ceiling wall 15 of the housing 11 are opened, and garbage is put into the first and second garbage treatment tanks 18a and 18b. In this state, the fan heater 46 is operated, the air sucked from the inlet duct 47 is heated by the fan heater 46 and supplied to the heated air supply duct 44 from the connection pipe 48, and the motors 36 and 36 are driven to rotate the rotating shaft 34. , 34 are rotated, and in addition to this, the discharge blower 50 is operated, and the heated air inside the first and second garbage disposal tanks 18a, 18b is heated to the heated air discharge duct 45. Then, the gas is discharged through the connecting pipe 49, the heating pipe 25, the connecting pipe 51, the discharge blower 50, and the outlet duct 52.
[0030]
The garbage thrown into the first and second garbage treatment tanks 18a and 18b is heated by the heated air supplied from the heated air supply duct 44 while being stirred by the stirring blades 40, 42, and the panel. By heating with the heat generated by the heaters 27 and 28 and the heated air flowing inside the heating pipe 25, a small amount of residue is fermented by the action of a microorganism group in which facultative anaerobic bacteria and aerobic bacteria are mixed. Generate. At this time, carbon dioxide and water (steam) generated by fermentation of the garbage are discharged to the outside of the first and second garbage treatment tanks 18a and 18b through the heated air discharge duct 45 together with the heated air. And the produced | generated residue can be taken out from the 1st, 2nd garbage processing tank 18a, 18b by opening the discharge port opening-and-closing door 69 .... In addition, the said residue can be utilized as a fertilizer, a soil improvement material, or a fermentation promotion material.
[0031]
While the heated air from the fan heater 46 flows from the front end side (the right side in FIG. 6) to the rear end side (the left side in FIG. 6) of the heated air supply duct 44, the heated air supply duct 44 passes through the seven heated air supply ports 44a. 1. It flows into the second garbage processing tanks 18a, 18b, but if the opening degree of the seven heating air supply ports 44a is uniform, the heating air supply port 44a on the front end side of the heating air supply duct 44 Since the amount of heated air flowing in increases and the amount of heated air flowing in from the heated air supply port 44a on the rear end side decreases, the heated air is uniformly distributed throughout the first and second garbage disposal tanks 18a and 18b. Can no longer supply. Therefore, as shown in FIG. 6, the positions of the lid bodies 53 of the seven heated air supply ports 44a are individually adjusted, the opening degree of the heated air supply port 44a on the front end side is reduced, and the rear end side heating is performed. By increasing the opening degree of the air supply port 44a, the heated air can be uniformly supplied to the entire first and second garbage disposal tanks 18a and 18b.
[0032]
The heated air inside the first and second garbage disposal tanks 18a and 18b is sucked into the eight heated air discharge ports 45 of the heated air discharge duct 45 by the discharge blower 50. If the opening degree of the discharge ports 45a is uniform, the amount of heated air sucked from the heated air discharge port 45a on the front end side (right side in FIG. 6) of the heated air discharge duct 45 is reduced, and the rear end side (FIG. Since the amount of heated air sucked from the heated air discharge port 45a on the left side in FIG. 6 increases, the heated air cannot be uniformly sucked from the entire first and second garbage disposal tanks 18a and 18b. Therefore, as shown in FIG. 6, the positions of the lids 56 of the eight heated air discharge ports 45a are individually adjusted, the opening degree of the heated air discharge port 45a on the front end side is increased, and the rear end side heating is performed. By reducing the opening degree of the air discharge port 45a, the heated air can be uniformly sucked from the entire first and second garbage disposal tanks 18a and 18b.
[0033]
By the way, since heated air is ejected from the heated air supply port 44a ... of the heated air supply duct 44, the garbage scraps scattered and scattered inside the first and second garbage treatment tanks 18a, 18b. Although there is no risk of entering the inside of the heated air supply duct 44, the heated air discharge port 45a of the heated air discharge duct 45 sucks heated air. There is a risk of being sucked into the interior. However, in this example By arranging the heated air discharge port 45a on the upper surface of the heated air discharge duct 45 and below the input port opening / closing door 62 for throwing in garbage, and providing the lid 56 in the heated air discharge port 45a in an adjustable manner, Since the heated air discharge port 45a is opened on the upper surface of the heated air discharge duct 45, the garbage which is stirred and scattered under the heated air discharge port 45a is prevented from being sucked into the heated air discharge port 45a ... The clogging of the duct 45 can be reliably prevented. Moreover, since it is not necessary to arrange the heated air discharge duct 45 at a particularly high position with respect to the stirring blades 40, 42, etc. in order to prevent inhalation of garbage waste, the first and second garbage disposal tank 18a. , 18b can be lowered to facilitate the operation of charging garbage from the input port door 62.
[0034]
In addition, as shown in FIG. 5, in this embodiment, the tip of the right bottom wall 22 and the tip of the left bottom wall 24 facing each other are welded W1 and W1 to both side surfaces of the heating pipe 25. When the front end of the wall 22 and the front end of the left bottom wall 24 are directly abutted and welded, the joint may be distorted like a wave due to the heat of welding, and accuracy may be reduced. However, by interposing a highly rigid heating pipe 25 between the tip of the right bottom wall 22 and the tip of the left bottom wall 24 as in the present embodiment, it is possible to prevent the joint from being distorted and undulating. it can. In addition, since the heating pipe 25 is interposed, the joined portion of the right bottom wall 22 and the left bottom wall 24 is smoothly and continuously sharpened, so that garbage can be prevented from being caught there.
[0035]
When the amount of garbage to be treated is large, the treatment is performed using the two garbage treatment tanks 18a and 18b. However, the amount of garbage input into the both garbage treatment tanks 18a and 18b becomes uneven. In this case, the amount of garbage inside the both garbage processing tanks 18a and 18b because the excessively thrown garbage moves over the partition wall 26 and moves from one of the first and second garbage disposal tanks 18a and 18b to the other. Can be prevented from becoming extremely unbalanced. From this, even if garbage is introduced from only one of the two inlet opening / closing doors 62, 62, the treatment can be performed in the two garbage treatment tanks 18a, 18b. Of course, when the amount of garbage to be treated is small, the treatment can be performed using only one of the garbage treatment tanks 18a and 18b.
[0036]
By the way, the operation of the garbage fermentation treatment apparatus is basically performed continuously for 24 hours. However, when the garbage treatment is not performed on a holiday, the garbage fermentation treatment apparatus is operated for a necessary time to save power. Can be planned. Hereinafter, this method will be described based on the flowcharts of FIGS. 14 and 15.
[0037]
First, when the normal operation mode is selected by operating the normal / stop / discharge switching switch 88 in step S1, the normal operation mode is executed in step S2, and the stirring device (that is, the motors 36 and 36) and the air supply device (that is, the air supply device) The fan heater 46) and the exhaust device (that is, the exhaust blower 50) operate. In this normal operation mode, unless the holiday operation mode is selected by operating the holiday operation lamp pushbutton switch 90 in step S3, the opening / closing detection means 67, 67 are turned on in step S4, and the inlet opening / closing doors 62, 62 are turned on. It will continue unless it is detected that it has been opened. When the normal / stop / discharge switch 88 is operated to select the stop mode in step S5, the stop mode is executed in step S6, and the operations of the motors 36 and 36, the fan heater 46, and the discharge blower 50 are stopped. When the normal operation mode is being executed, when opening / closing doors 62 and 62 are opened in step S4 to put garbage into the first and second garbage disposal tanks 18a and 18b, the opening / closing detection means 67 and 67 are opened. In step S7, only the motors 36 and 36 are stopped while the fan heater 46 and the exhaust blower 50 are operating. As a result, the rotation of the stirring blades 40, 42,... Stops, and safety when the garbage is put in is ensured. When the input of the garbage is finished and the inlet opening / closing doors 62, 62 are closed, the opening / closing detection means 67, 67 are turned off in step S8, the process returns to step S2, and the normal operation mode is resumed.
[0038]
When the holiday operation mode is selected by operating the holiday operation lamp push button switch 90 in step S3 on the day before the holiday when no garbage is scheduled to be input, the holiday operation timer 91 is started in step S9 and the holiday is performed in step S10. The operation mode is executed, and the motors 36, 36, the fan heater 46, and the discharge blower 50 are operated. This holiday operation mode is continued if the opening / closing doors 62, 62 are opened in step S11 and the opening / closing detection means 67, 67 are not turned on. When the holiday operation timer 91 times out in step S12, holiday operation is performed in step S13. The mode ends, the motors 36 and 36 and the fan heater 46 stop operating, and only the discharge blower 50 continues to operate at a low speed. Therefore, when the last garbage is put on the day before the holiday, if the minimum time required for processing the garbage is set by the holiday operation timer 91, the garbage is processed after the garbage processing is finished. It is possible to prevent the waste fermentation processing apparatus from continuing the useless operation and increasing the power consumption.
[0039]
After the holiday operation mode is finished in step S13, when the opening / closing doors 62 and 62 are opened and the open / close detection means 67 and 67 are turned on in order to throw in garbage in step S14, the motors 36 and 36 are activated in step S15. When the fan heater 46 and the discharge blower 50 are operated normally while stopped and the inlet opening / closing doors 62, 62 are closed and the opening / closing detection means 67, 67 are turned off in step S16, the process returns to step S2 to return to the normal operation mode. To do. Also, before the holiday operation timer 91 times out in step S12, when the opening / closing doors 62 and 62 are opened to turn on garbage in step S11 and the open / close detection means 67 and 67 are turned on, the holiday operation timer in step S17. 91 is canceled and the process proceeds to step S15. Then, in step S15, the motors 36 and 36 stop operating while the fan heater 46 and the exhaust blower 50 are operated. In step S16, when the inlet opening / closing doors 62 and 62 are closed and the open / close detection means 67 and 67 are turned off, Return to S2 to return to the normal operation mode.

As described above, when the holiday operation mode is selected, before the holiday operation timer 91 expires (that is, during operation of the garbage fermentation treatment apparatus), the inlet opening / closing is performed so as to newly input garbage. Since the doors 62 and 62 are opened to return to the normal operation mode, the holiday operation timer 91 is timed up while the newly added garbage is not yet processed, and the garbage fermentation processing apparatus stops operating. Can be reliably prevented. In addition, after the holiday operation timer 91 has timed out and the garbage fermentation treatment apparatus has stopped operating, the opening / closing doors 62 and 62 are opened to newly introduce garbage, so that the normal operation mode is restored. It is not necessary to operate the normal / stop / discharge switch 88 in order to resume the operation of the garbage fermentation processing apparatus at the end of the day, and it is automatically performed by opening the inlet opening / closing doors 62 and 62 to newly input garbage. Therefore, it is possible to return to the normal operation mode and to forget the operation for returning to the normal operation mode after newly adding garbage.
[0041]
In addition, in order to discharge the residue inside the first and second garbage processing tanks 18a, 18b, after the stop mode is selected with the normal / stop / discharge switch 88 and the operation of the garbage fermentation processing apparatus is stopped. The discharge opening / closing door 69 is opened, and the forward / stop / reverse selector switch 89 is operated in the forward or reverse position. As a result, the stirring blades 40, 42,... Rotate forward or reverse and the residue is automatically discharged.
[0042]
As mentioned above, although the Example of this invention was explained in full detail, this invention can perform a various design change in the range which does not deviate from the summary.
[0043]
For example, in the embodiment, a two-shaft type garbage fermentation processing apparatus provided with two rotating shafts 43 and 43 is illustrated, but the present invention is directed to a single-axis or three-axis or more garbage fermentation processing apparatus. Can also be applied.
[0044]
【The invention's effect】
As described above, according to the invention described in claim 1, The heated air outlet is located on the upper surface of the heated air outlet duct and below the open / close door for throwing in garbage, and the heated air outlet has an adjustable lid. Therefore, garbage scraps stirred and scattered by the stirring blades rotating below it are prevented from being sucked into the heated air discharge duct from the heated air discharge port together with the heated air, thereby reliably preventing clogging of the heated air discharge duct. be able to. As a result, it is not necessary to provide the heated air discharge duct at a particularly high position, and the height of the garbage processing tank can be lowered to facilitate the operation of charging garbage.
[0045]
Further, according to the invention described in claim 2, since the opening degrees of the plurality of heating air supply ports can be adjusted independently, the heating air supply is performed along the flow direction of the heating air in the heating air supply duct. By changing the opening of the mouth, heated air can be uniformly supplied to the inside of the garbage treatment tank, and the opening of the plurality of heated air discharge ports can be adjusted independently, so that heating By changing the opening degree of the heated air discharge port along the flow direction of the heated air in the air discharge duct, the heated air inside the garbage treatment tank can be discharged uniformly.
