Further, the control means is provided with operation means for manually controlling the stirring means, the heating means and the exhaust means by switching the control by the control means to manual control.

  7 of the present invention is the toilet excrement disposal apparatus in a moving body of 1, 2 or 3 of the present invention, wherein when the moving body is stopped, the exhausting operation of the exhausting means is stopped or the light wind operation is stopped. It is configured to control as much as possible.

  According to the toilet excrement disposal apparatus in a moving body of 1 of the present invention, the waste introduced from the toilet in the moving body is heated, stirred, exhausted, and moisture in accordance with its moisture state. By controlling the operation of the supply means, the moisture state of the treatment object including the excrement is appropriately maintained as much as possible to keep the activity of the microorganisms well, and the treatment object including the excrement introduced thereby can be speedily processed. And can be decomposed well. Therefore, there is no need to unnecessarily configure the treatment tank installed in the moving body. Similar to the existing apparatus using microorganisms, since the decomposition process is performed in a moving body such as a vehicle or a ship, ground equipment for extracting and processing excrement is not required.

  According to the toilet excrement disposal apparatus 2 in the moving body of the present invention, there is no possibility that the filter of the exhaust duct is clogged. When the exhaust means is used for a long period of time, the filter may be clogged with the base powder. However, in the second aspect of the present invention, the clog prevention means is operated periodically or irregularly, It is possible to easily remove the clogging by removing the substrate powder and the like that are being deposited on the filter.

  As the clogging prevention means, the exhaust fan that can be reversed is adopted, and as described above, the clogging of the filter is removed by performing the reverse rotation periodically or irregularly. . Or, it consists of a purified water pipe connected between the exhaust fan of the exhaust duct and the filter and an on-off valve arranged in the middle, and opens the on-off valve periodically or irregularly to eject purified water into the exhaust duct. And the filter can be cleaned. Alternatively, it can be constituted by a compressed air introduction pipe provided with a normally closed on-off valve connected between the filter of the exhaust duct and the exhaust fan. In this case, the normally closed on-off valve is opened, compressed air is introduced and ejected through the compressed air introduction pipe between the filter and the exhaust fan, and the compressed air flows back to the treatment tank side in the reverse direction through the filter. By doing so, the clogging can be avoided.

  According to the toilet excrement disposal apparatus 3 in the moving body of the present invention, the deodorizing means is arranged in the middle of the exhaust duct, and the odor of the excrement from the processing tank, the odor from the product by the microorganisms, etc. It is possible to exhaust after deodorizing with. Therefore, it is possible to reduce the risk of spreading bad odors.

  According to the toilet excrement disposal apparatus 4 in the moving body of the present invention, the state of the object to be treated including the excrement in the treatment tank can be maintained in a state suitable for the treatment of microorganisms in most of the time. it can. Alternatively, even if the state suddenly deteriorates, it can be quickly returned to a suitable state. If the state of the to-be-processed object including the excrement in the treatment tank is left as it is, it changes depending on the excrement that is sequentially introduced. The amount of excrement input varies depending on the number of passengers and the time zone. If there is a temporary increase in the number of passengers, in many cases the amount of excreta will also increase. In some cases, a large amount of excrement is temporarily added, and the inside of the treatment tank may suddenly become excessively watery. Depending on the time of day, only the amount of urination increases, and it may become excessively watery as well. The number of passengers is small, and the amount of waste discharged into the treatment tank may be reduced for a relatively long time. In such a case, moisture may be insufficient. Of course, there is a balance between the excrement input and the treatment with microorganisms, and a normal moisture state may be maintained.

  In the toilet excrement disposal apparatus 4 in the moving body of the present invention, the moisture state of the object to be treated including the excrement in the treatment tank that changes in various ways as described above is detected by the moisture sensor, and the state is insufficient. In any case of excess water or normal, the control means appropriately controls the stirring means, heating means, exhaust means and moisture supply means to cope with these conditions, and the moisture state of the workpiece Is operated so as to lead to the normal state or to maintain the normal state, the activity of the microorganisms is always activated, and the good decomposition activity of the object to be treated can be maintained. Therefore, the decomposition speed of the object to be processed in the processing tank is high, and the object to be processed including a large amount of excrement can be decomposed in a relatively small processing tank. Therefore, it is suitable for use as equipment attached to the moving body.

  According to the toilet excrement disposal apparatus 5 in the moving body of the present invention, the excessive moisture level is divided into two, and when the moisture state of the object to be processed is slightly excessive, the heating is commensurate with it. When the ratio of excess water is very high by the gentle operation of the means, the stirring means and the exhaust means, the rapid operation of the heating means, the agitation means and the exhaust means corresponding to it is very high. By doing so, the normal state can be quickly recovered. Due to a sudden increase in the number of passengers and the like, the moisture state of the object to be processed may become excessively watery, and the moisture ratio may become very high within a short time. In such a case, if the heating means is operated in the same way as when the amount of water is slightly excessive, it takes too much time to return to the normal moisture state, and the decomposition treatment of the object to be processed by microorganisms There is a risk of hindering the good progress of the process. According to the toilet excrement disposal apparatus 5 in the moving body of the present invention, this is solved by dividing the excessive water level into two and changing the control method.

  It should be understood that the excessive water levels X and Y are obtained by dividing the level 2 in the examples described later into two according to the excessive water level. Specifically, in the embodiment, since the moisture content of the object to be processed is 40% or more and less than 70% in level 2, the excess moisture level X is, for example, 40% or more and less than 55%, and the excess moisture level Y Can be 55 or more and less than 70%.

According to the toilet excrement disposal apparatus 6 in the moving body of the present invention, the manager of the excrement disposal tank indicates the amount, temperature, pH, moisture state, and exhaust air volume of the object to be processed in the treatment tank. If it is possible to monitor through the monitor and it is determined that the current operation of the stirring means, heating means and exhaust means is inappropriate from the viewpoint of data indicating the state of the object to be processed, etc. These can be manually controlled via the operation means, and more appropriate processing apparatus can be operated. For example, if the exhaust air flow is below a predetermined value, the exhaust duct filter may be clogged, so the manual operation will open the on-off valve of the compressed air introduction pipe connected to the exhaust duct. The compressed air is introduced into the exhaust duct and is caused to flow toward the treatment tank, so that the filter can be clogged or the exhaust fan may be broken. Proper driving will be possible.
In addition, since warning display or warning action is performed based on some more important detection results, the administrator can hardly overlook the important detection results and can perform appropriate processing promptly. .

  According to the toilet excrement disposal apparatus for a moving body according to 7 of the present invention, an unpleasant excrement odor in the station premises or the like is obtained by stopping the exhausting operation of the exhausting means when the moving body stops at the station or the like, or by causing a slight wind operation. Etc., so that passengers in the station are not uncomfortable.

  The best mode for carrying out the present invention will be described based on examples with reference to the drawings.

  The box-shaped case 1 is provided with a heat insulating material (not shown) on its outer surface to keep the inside warm, and its upper surface is also closed. In this embodiment, the box-shaped case 1 is not shown in the approximate center on the main chamber 1a side. An opening 1ah connected to a pipe extending from a toilet in the train is opened, and a connecting flange for connecting to the pipe is formed on the periphery thereof. As described above, the opening 1ah is opened near the upper center of the main chamber 1a in this embodiment. However, the opening 1ah is not limited to this and can be opened at any position.

  The box-shaped case 1 has an internal inspection that also serves as a base material inlet that can be opened and closed by a lid 13a having one end connected to the upper part of the main chamber 1a end via hinges 13h and 13h. An opening 13b is formed, and a workpiece outlet 14b closed by a lid 14a that can be opened and closed is opened below the opening 13b. The lid 14a of the workpiece outlet 14b is securely fixed with a bolt member (not shown) so that the workpiece outlet 14b can be closed securely. The lid 13a of the internal inspection port 13b is provided with known locking means 13L at the end opposite to the side connected by the hinges 13h and 13h, so that the closed state can be reliably maintained. It is like that. In addition, in this Example, although comprised in this way, the position of the internal inspection port 13b and the to-be-processed object outlet 14b, the structure of the cover bodies 13a and 14a, etc. are not restricted to this, It can produce freely. is there.

  The processing tank 2 is basically a box-shaped container having an upper opening, but in this embodiment, as described above, two rotary stirring means 3 along the length direction thereof are provided. 3 are arranged in parallel, and in order to correspond to this, as shown in FIG. 3 (b), the bottoms of both sides are arranged at the tips of the rotary blades 3b, 3b. A cross-sectional arc is formed along the drawn arc. In this embodiment, the processing tank 2 has a capacity of 375 L, and among them, the capacity of a base material, which will be described later, is 200 L.

  The rotary stirring means 3, 3... Are arranged along the length direction inside the processing tank 2 as described above and as shown in FIGS. Near both ends of the rotating shafts 3a, 3a are rotatably supported by bearings (not shown) disposed at both ends of the processing tank 2, respectively, on the side extending through the boundary wall with the sub chamber 1b and extending into the sub chamber 1b. As described above, the end portion is connected to the electric motors 6 and 6 disposed in the sub chamber 1b via the rotation transmission means.

  As shown in FIGS. 3B and 4, the rotary stirring means 3 and 3 are arranged in the direction perpendicular to the axis of the rotary shafts 3 a and 3 a and the rotary shafts 3 a and 3 a in this embodiment. Are composed of a plurality of stirring blades 3b, 3b,. The agitating blades 3b, 3b,... Are constituted by a blade shaft 3b1 attached perpendicularly to the rotation shafts 3a, 3a and a blade member 3b2 having a V-shaped cross section attached to the blade shaft 3b1. The blade member 3b2 is fixed to the blade shaft 3b1 so that the blade shaft 3b1 is held by the V-shaped groove-like portion. The stirring blades 3b, 3b,... Are attached to the rotating shaft 3a while changing the adjacent angles by 90 degrees. Further, the adjacent stirring means 3 and 3 are configured such that the mutual stirring blades 3b, 3b... Enter between the adjacent stirring blades 3b and 3b.

  The rotation transmission means (not shown) interposed between the rotating shafts 3a and 3a of the rotary stirring means 3 and 3 and the electric motors 6 and 6 can freely employ various types such as a gear train, a chain and a chain wheel. Is possible. In this embodiment, the rotation transmission means is composed of a chain wheel and a chain.

  The silicon cord heaters 4, 4... Are cord-shaped heaters in which a nichrome wire is covered with silicon rubber. As shown in FIG. 3 (b), the silicon cord heaters 4, 4. Are arranged in parallel with each other at regular intervals. Note that the heating means is not limited to this, and it is needless to say that a surface heater or the like can be freely employed as long as an object to be processed inside the processing tank 2 can be appropriately heated. Alternatively, the exhaust heat of the vehicle engine or the generated heat of the electric motor can be used by exchanging heat using some liquid heat medium or the like.

  As shown in FIGS. 4 and 5A, the exhaust means 5 includes an exhaust duct 5b, a filter (not shown) located at the end of the exhaust duct 5b on the processing tank 2 side, a deodorizing tank 5a, and an exhaust fan 5c. The exhaust duct 5b is opened from the boundary wall with the sub chamber 1b in the upper part of the treatment tank 2 in the main chamber 1a, and the filter is disposed in the opening. The exhaust fan 5c is interposed in the middle of the opening and connected to the deodorizing tank 5a in the sub chamber 1b. Further, it extends into the atmosphere from the side of the deodorizing tank 5a and opens to the atmosphere at the outer end. This opening is the exhaust port 5d. An electromagnetic opening / closing valve (not shown) is inserted immediately before the exhaust port 5d of the exhaust duct 5b. Further, as shown in the figure, a compressed air introduction pipe 5e provided with a normally closed electromagnetic on-off valve (not shown) is connected to a portion of the exhaust duct 5b immediately adjacent to the treatment tank 2 side of the exhaust fan 5c. The other end of the compressed air introduction pipe 5e is connected to a compressor tank provided in the vehicle.

  The exhaust means 5 sucks various gases generated in the treatment tank 2 by the exhaust fan 5c through the filter at the opening end on the treatment tank 2 side, introduces the gases into the deodorization tank 5a, and deodorizes them. Then, the deodorized exhaust is discharged from the side portion, and is discharged into the atmosphere through the exhaust port 5d at the outer end. When the vehicle is stopped at a station or the like, the operation of the exhaust fan 5c is stopped and the electromagnetic on-off valve in the exhaust duct 5b is closed so that the exhaust is not discharged from the exhaust port 5d. Although this exhaust means 5 deodorizes and exhausts, since the odor is not completely removed, this is intended to prevent the passengers from feeling uncomfortable. is there. Further, the compressed air introduction pipe 5e opens an electromagnetic on-off valve therein as necessary (regularly or irregularly), and sends compressed air that flows back to the treatment tank 2 side to the exhaust duct 5b. In order to prevent clogging of the filter. This is because the filter may be clogged with the base powder that may be discharged from the treatment tank 2 together with the exhaust gas.

As the exhaust fan 5c, an exhaust air volume that can be adjusted is adopted. Exhaust air volume, in this embodiment, the case of level 0 determined by the moisture percentage (for lack of water) to 1 m ³ / min below to the object to be treated, in the case of level 1 (the case of water normal) to 3m ³ / min In the case of level 2 (in the case of excessive moisture), it was set to be adjusted to 4.5 m ³ / min. Such control of the exhaust air volume for the exhaust fan 5c is performed by the control means. The control means receives the detection signal from the workpiece moisture measuring sensor 8 to determine whether the level is 0 to 2, and controls the exhaust fan 5c as described above in response. Of course, other settings of the above-described exhaust air volume are possible in relation to various other configurations.

  The deodorizing tank 2 is filled with a substrate carrying a deodorizing complex microorganism. In this example, a piece of wood to which activated sludge was adhered was adopted as the substrate carrying the composite microorganism, and this was filled. In this way, the malodorous gas introduced from the treatment tank 2 is decomposed and is not brominated. The tree species of the wood piece is not limited, but in this example, a cedar piece of a cube or a rectangular parallelepiped having a side of about 5 to 10 mm was used. A cedar piece of such a size was adopted as a piece of wood, and the combined proportion of the activated sludge to be attached to this piece of wood was such that the activated sludge was about 5 to 20% in terms of volume. The purpose of this is to increase the area of contact with the malodorous gas to be processed and to facilitate the passage of malodorous gas during the activity of microorganisms, while reducing the pressure loss. In addition, the capacity | capacitance of this deodorizing tank 2 was 31 L in this Example. Further, a drain port (not shown) is opened at the bottom of the deodorizing tank 2 so that water can be drained through a drain pipe connected thereto.

  In this embodiment, the activated sludge is a concentrated activated sludge that retains the fluidity generated in a sewage treatment plant or human waste treatment plant. Other activated sludges can be used.

  As described above, the electromagnetic on-off valve immediately before the exhaust port 5d of the exhaust duct 5b is closed when the vehicle stops at the station to stop exhaust emission, which is uncomfortable for passengers getting on and off passengers and other passengers passing through the platform. Don't make me think. The above-described operation of the electromagnetic on-off valve is performed by determining whether or not the vehicle on which the valve is mounted is stopped by receiving the vehicle speed signal supplied from the vehicle speed sensor provided in the vehicle. Control. The stop of the vehicle can be determined using various other signals. For example, it is possible to determine that the vehicle is stopped when a door opening / closing signal is supplied from the vehicle and this indicates that the vehicle is open. Further, for example, a unique vehicle speed sensor using an acceleration sensor is provided. It is also possible to create and use this.

  As described above, the electric motors 6 and 6 are respectively connected to the rotary shafts 3a and 3a of the rotary stirring means 3 and 3 through the rotation transmitting means, and are controlled by the control means to rotate the rotation. The stirring means 3 and 3 can be rotated forward and backward at a desired rotational speed. In this embodiment, the operations of the rotary stirring means 3 and 3 are configured so as to repeat “forward rotation-stop-reverse rotation-stop-”, respectively, and the respective times are as follows. When the moisture ratio is level 0, the operation is completely stopped, and when it is level 1, “repetition of forward 3 minutes-stop 1 minute-reverse 3 minutes-stop 1 minute-” is set to level 2 In this case, “repetition of forward rotation 4 minutes−stop 1 minute−reverse 4 minutes−stop 1 minute−” is set. In this embodiment, the rotation speed is 3.3 rpm. Various settings can be made according to the specific circumstances, but in the case of the processing tank 2 having the size as in this embodiment, when the two rotary stirring means 3 and 3 are arranged in parallel, the rotational speed is It can be set in a range of approximately 2 to 5 rpm.

  The air inlet 7 is open to the top plate near the end of the main chamber 1a of the box-shaped case 1 as shown in FIGS. 1, 2, 3 (a), 3 (b) and 5. This is opened by changing the direction in the extending direction of the end with a guide body, and an electromagnetic opening / closing valve (not shown) is provided inside. In this embodiment, the electromagnetic open / close valve is configured to be opened and closed in conjunction with the electromagnetic open / close valve of the exhaust duct 5b of the exhaust means 5 by the control means.

  As shown in FIG. 4, the purified water supply pipe 16 reaches the boundary wall with the main chamber 1 a from the outside of the sub chamber 1 b through the sub chamber 1 b, penetrates the upper portion thereof, and reaches the upper portion of the treatment tank 2. It is an open pipe, and the end on the side extending from the sub chamber 1b is connected to a water purification tank mounted on the vehicle.

The processing object amount sensor 15 measures the amount of the processing object consisting of excrement and a base material. In this embodiment, an ultrasonic position sensor is used, and thereby the level of the upper surface of the processing object is determined. It is to be measured. Accordingly, the ratio of the object to be processed to the capacity of the processing tank 2 can be detected. In this embodiment, the amount of the object to be processed is measured by measuring the bulk. However, it goes without saying that the weight may be measured instead.

  As shown in FIGS. 1 to 3 (a), (b) and FIGS. 5 (a), (b), the in-tank camera 12 is arranged on the main chamber 1a side of the box-shaped case 1 in this embodiment. It is fixed on the top plate near the end in a state of being installed in a protective case. The lower surface of the protective case is in an open state. On the other hand, the corresponding part of the top plate of the main room 1a is partially made of transparent glass, and the camera body of the in-tank camera 12 is seen through the glass. The inside of the tank can be photographed. The tank camera 12 is provided with an illumination lamp so as to illuminate the inside of the tank.

Note that a touch panel configured as an image monitor may be employed instead of the keyboard.

In this embodiment, the control means is configured to perform the following control operation.
The first is an operation for preventing clogging of the filter of the exhaust duct 5 b of the exhaust means 5.
This is because the electromagnetic on-off valve is opened only for 1 second from the compressed air introduction pipe 5e connected to the exhaust duct 5b on the treatment tank 2 side and closer to the exhaust fan 5c than the exhaust fan 5c. Compressed air generated by a vehicle compressor is introduced into the exhaust duct 5b, and the base powder or the like accumulated on the filter of the exhaust duct 5b is caused to flow back into the processing tank 2 and removed. is there.

The second is processing when the temperature of the object to be processed becomes abnormally low.
When the detected temperature signal, which is the temperature of the object to be processed, is received from the object temperature sensor 9 and it is determined that the temperature is lower than 4 ° C., the rotation operation of the rotary stirring means 3 and 3 is stopped simultaneously. A warning display indicating that the temperature has dropped is displayed on the image monitor, and a buzzer is sounded. Then, the temperature of the silicon cord heaters 4, 4... Is increased to 120 ° C., and the operation of the exhaust fan 5c of the exhaust means 5 is stopped.

The third is processing when the amount of the object to be processed exceeds the reference value.
When the upper surface level signal of the object to be processed is received from the object amount sensor 15 and it is determined whether or not the upper surface level signal of the object to be processed exceeds a certain ratio with respect to the capacity of the processing tank 2 as a reference value. Displays an indication of the suspension of use on the image monitor and sounds the buzzer.

The fourth is a treatment when the pH of the workpiece exceeds a reference value.
In this embodiment, as will be described later, since a microorganism that is active in an acidic state is used, a treatment is performed when the pH value that is the limit is exceeded. That is, when the detected pH signal of the object to be processed is received from the pH measurement sensor 10 and it is determined that the detected pH signal exceeds 7.2, a warning display to that effect is displayed on the image monitor. This indicates that the microbial activity is not being performed properly, so the administrator should review all other data in detail and observe the condition of the work piece and take appropriate action. And Manual control of each operation such as the operation of the rotary stirring means 3 and 3, the heating operation of the silicon code heaters 4, 4... And the exhaust operation of the exhaust means 5, addition of moisture, addition of the microorganism substrate, and other processing are performed.

No. 5 is processing according to the level of the moisture ratio of the workpiece.
In this process, the moisture content detection signal of the workpiece is received from the workpiece moisture measuring sensor 8, and it is determined whether the moisture percentage level belongs to 0, 1, or 2, depending on each case. The rotary stirring means 3, 3, silicon code heaters 4, 4..., The pump device and the electromagnetic on-off valve of the purified water supply pipe 16 and the operation of the exhaust means 5 are controlled. When the exhaust operation of the exhaust means 5 is controlled, the upper space of the processing tank 2 becomes atmospheric pressure or the pressure is reduced to various levels, and the introduction of air from the air inlet 7 is automatically controlled accordingly. Will be.

  The level of the moisture ratio can be changed in various ways by an administrator while observing the progress of decomposition of microorganisms by the microorganisms depending on the season. An example is as follows. Level 0 = moisture content of the object to be treated is 10%, level 1 = moisture content of the object to be treated is 10% or more and less than 40%, and level 2 = water content of the object to be treated is 40% or more and less than 70%. When the water content of the object to be treated is 70% or more, the operation exceeds the range in which the normal activity of the microorganism can be recovered by the operation of the rotary stirring means 3, 3 and the like.

The detailed control operation of the control means in this case is as follows.
When the moisture content of the object to be processed is level 0, the exhaust means 5 makes the exhaust air flow 1 m ³ / min, the rotary stirring means 3 and 3 stop its operation, and the silicon cord The heaters 4, 4... Stop the heating operation, the pump device of the purified water supply pipe 16 is turned on, the electromagnetic on-off valve is opened, and the purified water is supplied to the treatment tank 2.
When the moisture content of the object to be processed is level 1, the exhaust means 5 sets the exhaust air flow to 3 m ³ / min, and the rotary agitating means 3 and 3 perform the normal rotation 3 minutes-stop 1 The operation of minute-reverse rotation 3 minutes-stop 1 minute- is repeated so that the temperature of the silicon cord heaters 4, 4... Is 60.degree. The valve is closed and the supply of purified water is stopped.
When the moisture content of the object to be processed is level 2, the exhaust means 5 sets the exhaust air flow to 4.5 m ³ / min, and the rotary stirring means 3 and 3 The operation of -stop 1 minute-reverse rotation 4 minutes-stop 1 minute- is repeated, the temperature of the silicon cord heaters 4, 4,... Is 120.degree. C., and the pump device of the purified water supply pipe 16 is turned off. The electromagnetic on-off valve is closed and the supply of purified water is stopped.

No. 6 is a display by the image monitor of the video by the in-tank camera 12.
In this embodiment, the detection result data of the object temperature sensor 9, the object amount sensor 15, the pH measurement sensor 10, the object moisture measurement sensor 8, and the exhaust air volume sensor 11 are usually displayed on the image monitor. The video of the in-vessel camera 12 is configured to be displayed on the image monitor in place of the detection result data of the sensors when the administrator operates and selects a keyboard as an input means.

The seventh is storage of detection result data of sensors.
When the detection result data of the workpiece temperature sensor 9, the workpiece amount sensor 15, the pH measurement sensor 10, the workpiece moisture measurement sensor 8, and the exhaust air volume sensor 11 are received, as described above, the image While displaying on a monitor, those data are preserve | saved at a memory | storage part. In this embodiment, the recording of these data is performed for 120 minutes, and the data before that is deleted each time new data is written.

The eighth is processing when the vehicle is stopped.
When a vehicle speed signal is received from the vehicle speed sensor of the vehicle and it is determined that this indicates that the vehicle is stopped, the operation of the exhaust fan 5c of the exhaust means 5 is stopped, and at the same time, the electromagnetic on-off valve and the air introduction of the exhaust duct 5b are stopped. The electromagnetic on-off valve of the mouth 7 is closed. This operation is canceled when it is determined that the vehicle speed signal received subsequently indicates that the vehicle has started to move, the electromagnetic on-off valve is opened, and the exhaust fan 5c operates normally. When the vehicle starts to move in this way, the normal operation is immediately started. In this embodiment, the vehicle speed sensor is used to determine the stop of the vehicle. However, as described above, other means can be employed, and in this case, the same operation is performed.

  In this embodiment, sawdust carrying acidophilic microorganisms was employed as the base material to be put into the treatment tank 2. As the acidophilic microorganism, Sulfolobus acidocaldarius (Succolobus acidocaldarius ATCC49426), Alicyclobacillus sendaiensis JCM11817, Bacillus genus bacteria, lactic acid bacteria, and the like can be used. In this example, Sulfolobus acid cardarius was employed.

In this embodiment, an in-tank temperature / humidity sensor constituted by a commercially available temperature / humidity sensor is arranged in the upper part of the main chamber 1. The temperature signal and humidity signal of the tank temperature / humidity sensor are input to the control means and displayed on the image monitor through the control means.
In addition, in FIGS. 1-5, 17a, 17b is an attachment piece for attaching this box-shaped case 1 to the bottom part of a vehicle.

  Hereinafter, the operation when the toilet excrement disposal apparatus in the railway vehicle of this embodiment is attached to the vehicle will be described. In this embodiment, excrement piping extended from a toilet (a toilet or a urinal) of a vacuum toilet is connected to the upper opening 1ah of the box-shaped case 1 and used. Of course, other types of toilets can be employed.

  First, the lid 13a is opened, and the base material carrying the acidophilic microorganisms is introduced into the treatment tank 2 in the main chamber 1a from the internal inspection port 13b which also serves as the base material inlet. The input amount is 200 as described above. After the insertion, the internal inspection port 13b is naturally closed with the lid 13a.

  Thereafter, operation of the toilet excrement disposal apparatus in the railway vehicle is started. This will be described with reference to the flowcharts shown in FIGS.

  As shown in step s1, first, the photographing operation of the in-tank camera 12 arranged on the top plate portion of the main chamber 1a of the box-shaped case 1 is started. Next, as shown in step s2, a response as to whether or not to change various reference value settings is obtained. As shown in FIG. 8, the “reference value setting and change” screen is displayed on the image monitor of the control means, and it is required to respond to the screen. Specifically, as shown in the figure, the reference values of the moisture content levels 0, 1, and 2 are set, and three types of exhaust air flow values by the exhaust means 5 corresponding to the levels 0, 1, and 2 are set. , Setting of three types of heater temperature values corresponding to the silicon code heaters 4, 4... In the same case, setting of corresponding three types of operation modes of the pump device of the purified water supply pipe 16 and the electromagnetic on-off valve in the same case. In the same case, the setting of the corresponding three types of rotational operation modes of the rotary stirring means 3 and 3, the setting of the amount (%) of the processing object that issues a warning, and the processing to stop the rotational stirring operation of the rotary stirring means 3 and 3 Columns for setting the lower limit temperature (° C) of the product, setting the pH value of the workpiece to be warned, and setting the data recording time are displayed, and whether or not to change the standard values entered in advance in these columns Response is required.

  If you don't need to make changes, simply click the Enter button. If it does so, it will transfer to step s4. If any change is desired, if the change button is clicked, the process proceeds to step s3, and the numerical value of the desired column in the screen displayed as shown in FIG. After rewriting all of the above, click the OK button. In this case, the process proceeds to step s4.

  Step s4 is an operation for preventing clogging of the exhaust duct 5b of the exhaust means 5. As described above, the electromagnetic on-off valve is opened for 1 second. Accordingly, compressed air generated by the compressor of the vehicle is supplied to the exhaust duct 5b from the compressed air introduction pipe 5e connected to the exhaust duct 5b on the processing tank 2 side and closer to the exhaust fan 5c than the exhaust fan 5c. The substrate powder and the like introduced and deposited on the filter of the exhaust duct 5b is caused to flow back into the treatment tank 2 and removed. In this embodiment, the clogging prevention operation is performed every time the operation is started.

  When this clogging prevention operation is completed, the process proceeds to step s5, and the control means includes the workpiece moisture measuring sensor 8, the workpiece temperature sensor 9, the pH measuring sensor 10, the workpiece amount sensor 15, and the exhaust air volume sensor. 11 and vehicle speed sensors provided in the vehicle respectively receive current detection result signals to be detected, and store them in the storage unit of the control means as shown in the next step s6.

  Subsequently, the latest detected temperature data of the workpiece temperature sensor 9 is read from the storage unit, and as shown in step s7, it is determined whether or not it is less than 4 ° C. If so, step s8. Then, the rotary stirring operation of the rotary stirring means 3 and 3 is stopped, and subsequently, as shown in step s9, a warning display is displayed on the image monitor of the control means, and the buzzer sounds at the same time. On the other hand, following the stop of the rotary stirring operation of the rotary stirring means 3, 3, the process proceeds to step s 10 where the silicon code heaters 4, 4... Are controlled to be heated up to 120 ° C., and further to step s 11. Then, the operation of the exhaust fan 5c of the exhaust means 5 is stopped. Along with this, the introduction of air from the air inlet 7 is also stopped. The above-mentioned operation stop of the rotating stirring means 3 and 3, warning display on the image monitor, buzzer sounding, heating operation of the silicon code heaters 4, 120 ° C. at 120 ° C. and operation stop of the exhaust fan 5 c are changed by the control means. It goes without saying that the stop state or operation continues until a control signal is issued or a manual forced change operation is performed.

  Thereafter, the process proceeds to step s5. As described above, the detection data from the various sensors is read into the control means, and subsequently, the data is stored in the storage unit in step s6. Then, the latest data of the workpiece temperature is read from the storage unit to the control means, and it is determined whether or not the workpiece temperature is less than 4 ° C.

  This time, normally, the temperature of the object to be processed should have increased due to the stop of the rotary stirring means 3, 3 and the temperature raising operation of the silicon code heaters 4, 4... The determination of s7 is “not lower than 4 ° C.”, that is, “No”, and the process proceeds to the next step s12.

  In step s12, the processing object amount, which is the latest detection data of the processing object amount sensor 15, is read from the storage unit, and it is determined whether or not this exceeds a reference value. This reference value is 80% shown as a standard value in FIG. 8 (80% of the capacity of the processing tank 2). If the current amount of the object to be processed exceeds this, the process proceeds to step s13. The use stop display is displayed on the image monitor, and the buzzer is sounded. In this case, the administrator manually stops the ringing of the buzzer and promptly prohibits the use of the toilet in the vehicle connected to the toilet excrement disposal device in this railway vehicle, and at a possible time (for example, When entering the vehicle base, etc., the lid 14a is removed, the workpiece outlet 14b is opened, and the overlying workpiece is taken out. After the removal, the lid 14a is naturally attached as it is. After that, naturally, the prohibition of use is canceled, and the operation is manually returned to step s5 to advance the operation.

  Thereafter, after the steps already described, the process proceeds to step s14 as shown in FIG. Even when the amount of the object to be processed does not exceed the reference value, the process naturally moves to step s14. In step s14, the latest pH data of the object to be processed output from the pH measurement sensor 10 is read from the storage unit, and it is determined whether or not this exceeds a reference value related to pH. As shown in FIG. 8, the reference value is “7.2”, which is adopted as a standard value in this embodiment. If the latest pH value of the object to be processed exceeds 7.2, the process proceeds to step s15, and a warning is displayed on the image monitor.

  If the pH is above 7.2, it is likely that the microbe is not performing well, so the administrator can review the display in the image monitor to determine the current operating status of the device, and Examine data indicating the state of the tank and the object to be processed, and manually switch the display on the image monitor to the image of the camera 12 in the tank, observe the state in the processing tank 2, and take appropriate measures. . For example, through manual control of each operation such as the operation of the rotary stirring means 3, 3, the heating operation of the silicon code heaters 4, 4,..., The exhaust operation of the exhaust means 5, the operation of the pump device of the purified water supply pipe 16 and the electromagnetic on-off valve. Water treatment, addition of microbial substrate or addition of nutrients, and other treatments.

  Thereafter, or when the pH value does not exceed “7.2”, the process proceeds to step s16, where it is determined whether the moisture content (%) of the object to be processed corresponds to level 0 or not. The In this embodiment, as shown in FIG. 8, the moisture content of the level 0 workpiece is less than 10%, the moisture content of the level 1 workpiece is 10% or more and less than 40%, and the moisture content of the level 2 workpiece The rate is set to 40% or more and less than 70%. In step s16, the latest moisture content data relating to the object to be processed of the object to be processed moisture measurement sensor 8 is read from the storage unit, and it is determined whether or not this exceeds the level 0 as described above. That is, it is determined whether it is less than 10%.

If it is determined that it is within this range, the routine proceeds to step s17, where the rotational stirring operation of the rotary stirring means 3, 3 is stopped, and the routine proceeds to step 18, where the heating operation of the silicon code heaters 4, 4,. , The operation of the exhaust fan 5c is controlled so that the exhaust air volume becomes 1 m ³ / min in step s19, and the purified water supply is performed so that the process proceeds to step s20 and purified water is supplied to the treatment tank 2. The pump device of the pipe 16 is turned on, and the electromagnetic on-off valve is opened. Thus, the object to be treated is treated so as not to proceed with drying, and is treated so as to activate the activity of microorganisms. It should be noted that the above-described rotation stirring means 3, 3, silicon code heaters 4, 4,..., Exhaust fan 5c, pump device of purified water supply piping 16, and electromagnetic on / off valve operation stop or predetermined operation are changed by the control means. Needless to say, the operation or the operation stop state is maintained until the control signal is given or a manual change operation is applied. Next, the process proceeds to step s21, the above control data is stored in the storage unit, the process returns to step s5, and thereafter the operation after step s5 is repeated.

When the moisture content of the object to be treated is not within the range of level 0 in step s16, the process proceeds to step s22, and this time, whether or not the moisture content of the object to be treated corresponds to level 1, that is, FIG. As shown, it is determined whether the moisture content of the workpiece is 10% or more and less than 40%. If it is determined that the value is within this range, the process proceeds to step s23 where the operation of the stirring condition A of the rotary stirring means 3 and 3 is performed. As shown in FIG. 8, the stirring condition A is forward rotation 3 minutes-stop 1 minute-reverse 3 minutes-stop 1 minute-. Next, the process proceeds to step s24, and the heating operation of the silicon code heaters 4, 4,... Is controlled to 60 ° C. Then, the process proceeds to step s25, and the exhaust is performed so that the exhaust air volume becomes 3 m ³ / min. The operation of the fan 5c is controlled, and the pump device of the purified water supply pipe 16 is turned off so that the purified water is not supplied to the treatment tank 2 by moving to step s26, and the electromagnetic on-off valve is closed. In this way, the object to be treated is considered to maintain an appropriate moisture state, and is treated to maintain the active activity of microorganisms. In this case, the rotation stirring means 3, 3, the silicon code heaters 4, 4,..., The exhaust fan 5c, the pump device of the purified water supply pipe 16, and the electromagnetic on-off valve are operated or stopped by a control signal or manual change. Until the change operation is received, the operation state or the stop state is similarly maintained. Subsequently, the process proceeds to step s21, the above control data is stored in the storage unit, the process returns to step s5, and thereafter the operation after step s5 is repeated.

If the moisture content of the object to be treated is not within the range of level 1 in step s22, it is determined that the moisture content of the object to be treated is 40% or more and less than 70% as shown in FIG. And immediately go to that step. Specifically, the process proceeds to step s27 and the operation of the stirring condition B of the rotary stirring means 3 and 3 is performed. As shown in FIG. 8, the stirring condition B is a repetition of forward rotation 4 minutes—stop 1 minute—reverse rotation 4 minutes—stop 1 minute—. Next, the process proceeds to step s28, and the heating operation of the silicon cord heaters 4, 4,... Is controlled to 120 ° C., and the process further proceeds to step s29 so that the exhaust air volume becomes 4.5 m ³ / min. The operation of the exhaust fan 5c is controlled. Further, the pump device of the purified water supply pipe 16 is turned off and the electromagnetic on-off valve is closed so that the process proceeds to step s30 and purified water is not supplied to the treatment tank 2. In this way, the object to be treated is treated to evaporate and remove excess moisture to return to an appropriate moisture state, and is treated to recover the active activity of microorganisms. In this case, the rotating stirring means 3, 3, the silicon code heaters 4, 4,..., The exhaust fan 5c, the pump device of the purified water supply pipe 16, and the operation state or non-operation state of the electromagnetic on-off valve are also controlled by a control signal or It goes without saying that the operation state or the non-operation state is maintained until a manual change operation is received. Subsequently, the process proceeds to step s21, the above control data is stored in the storage unit, the process returns to step s5, and thereafter the operation after step s5 is repeated.

  The normal operation of the toilet excrement disposal apparatus in a railway vehicle is as described above. However, when a vehicle equipped with this device stops at a station or the like, the control means sends a vehicle speed signal from the vehicle speed sensor. When it is received and it is determined that this indicates a stop of the vehicle, the operation of the exhaust fan 5c of the exhaust means 5 is stopped, and at the same time, the electromagnetic open / close valve of the exhaust duct 5b and the electromagnetic open / close valve of the air inlet 7 are closed. Let This operation is canceled when it is determined that the subsequently received vehicle speed signal indicates that the vehicle has started to move, both electromagnetic on-off valves are opened, and the exhaust fan 5c operates normally. When the vehicle starts to move in this way, the normal operation is immediately started.

  Also, during the normal operation, when the pH of the workpiece exceeds 7.2, when the temperature falls below 4 ° C, when other abnormalities are detected by sensors, or when other problems are felt Can be manually switched to display the image of the in-vessel camera 12 on the image monitor, and the inside can be observed in detail. For example, it is possible to check the mixing of foreign matters that hinder the stirring operation of the rotary stirring means 3 and 3 such as stockings.

  In addition, the state of the object to be processed is inappropriate in the operation of the current rotating stirring means 3, 3, silicon code heaters 4, 4,..., The exhaust fan 5c, etc. from the viewpoint of appearance or displayed data. If it is determined that, it is possible to manually control them through the keyboard of the control means, and more appropriate operation of the treatment tank 2 can be performed. Specifically, per unit time of the exhaust fan 5c, which changes or stops the heating pattern of the silicon code heaters 4, 4,. For example, the exhaust air volume is changed or stopped.
