[0002]

2. Description of the Related Art Conventionally, for use in field battles and disaster areas,
2. Description of the Related Art A vehicle-mounted toilet configured to be movable by attaching a toilet unit having a plurality of toilets to a chassis of a truck or a trailer and a human waste tank is used. The applicant has previously noted that the processing capacity of a vehicle-mounted toilet equipped with a conventional sewage tank is low,
In order to improve the hygienic inferiority, a device equipped with a septic tank instead of a human waste tank was proposed (Japanese Patent Application No. 09-194826).
issue). In this case, since the lower part of the heavy septic tank is supported by the rear wheels, the septic tank is arranged at the rear end of the chassis, and the toilet room and the machine room are sequentially arranged from there to the front. Was.

[0003]

However, in such a configuration, when the weight of the portion of the septic tank that overhangs rearward from the rear wheel is too large, the front wheels, which are the steered wheels, may be displaced depending on the axial positions of the front and rear wheels. The load to be reduced is reduced and it is difficult to optimally set the ratio of the load to be carried by the front and rear wheels.In the case of a trailer, when removing the tractor and supporting the front of the platform with outriggers, the weight of the rear becomes excessive. Posture sometimes became unstable.

[0004]

An object of the present invention is to provide a lavatory unit comprising several chambers provided with a toilet in a packing box supported by an undercarriage, and located forward of the lavatory unit in the traveling direction. It is solved by installing a septic tank. Further, a machine room is provided at the front side of the septic tank, and the septic tank has a treatment tank on the toilet unit side,
Moreover, it is preferable to arrange the water storage tank toward the machine room.

[0005]

In a first aspect of the present invention, a septic tank that accommodates a large amount of water and filth and has an extremely large weight is disposed on the front side in the traveling direction of a lightweight toilet unit having a large space. Therefore, the center of gravity of the on-vehicle type toilet moves forward as compared with the conventional product, and the toilet unit can be disposed overhanging behind the rear wheel. [Claim 2] Although the sewage generated in the toilet unit contains solid matter and has low fluidity, the toilet unit and the septic tank are adjacent to each other, so that long piping is not required. Further, since the water tank of the septic tank and the machine room are close to each other, the treated water in the water tank is circulated to the deodorizing and decolorizing means provided in the machine room through a relatively short pipe. The treated water in the water storage tank is sent to the toilet unit by a pump provided in the machine room.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. Figures 1-3
Among them, reference numeral 10 denotes a vehicle-mounted toilet using the present invention. The on-board toilet 10 is configured as a packing box 12 of a trailer towed by a tractor 11 or as a packing box 12 mounted on a rear packing bed of a truck (not shown). Reference numeral 13 denotes a chassis which supports the packing box 12, and a rear portion is supported by a rear wheel 14, and a front portion is supported by a front wheel 15. The front wheel 15 is provided mainly to support the front part when the trailer is separated from the tractor 11, and may be replaced by the outrigger 16. The carton 12 has a machine room 20 from the front to the rear of the vehicle such as the tractor 11 or a truck,
A toilet unit 40 including a septic tank 30 and several chambers provided with a toilet B is sequentially accommodated. 50 is a sewage pump unit installed on the rear lower surface of the chassis.

The machine room 20 is provided with a diesel generator 21 serving as a power source for the on-vehicle type toilet 10, a blower pump F, a switchboard, and valves interposed in various pipes as necessary. An opening / closing door 22 for performing the operation is provided. The position of the machine room 20 is provided at the forefront of the packing box 12, so that the septic tank 30 and the toilet unit 40 can be adjacent to each other. The length of the pipe 62 can be reduced. In addition, the machine room 20 is
The water tank inside can be approached, and the treatment of treated water is simplified.

As shown in FIG. 6, the inside of the purification tank 30 is a primary treatment tank 3 having two tanks as a pair from the rear to the front.
1, a secondary treatment tank 32, a sedimentation tank 33, a tertiary treatment tank 34, and a water storage tank 35. Each tank 3
1 to 35 are partitioned by wall plates 31a to 35a and the like. The upper part of each of the wall plates 31a to 35a extends to the ceiling where the water in each tank does not move mutually due to the ripples generated while the trailer 10 is running, and is connected to an adjacent tank by a small hole so that the required minimum source is provided. Only movement is allowed.

The primary treatment tank 31 contains anaerobic microorganisms and decomposes organic matter in human waste into water, methane, hydrogen and the like in an environment where the air is cut off. The generated gas is released to the outside air through the louver 17. The secondary treatment tank 32 is a so-called aeration tank to which air is sent to activate aerobic microorganisms, and is supplied with compressed air by a blower pump F installed in the machine room 20. Reference numeral 36 in the tank denotes a laminated plate, which has a large number of vertically extending synthetic resin plates juxtaposed at predetermined intervals to adhere aerobic microorganisms thereto. The aerobic microorganisms obtain oxygen from a large number of air bubbles that float from the diffuser block 37 installed below, convert organic matter in human waste into water and carbon dioxide gas, and the carbon dioxide gas flows from the upper louver 17 into the atmosphere. Release to Primary processing tank 31 and secondary processing tank 32
As a result, the human waste that has been subjected to the organic matter decomposition treatment enters the sedimentation layer 33 from below as sewage, slowly rises, removes suspended matter, and flows to the tertiary treatment tank 34.

The tertiary processing tank 34 is configured as an aeration tank similar to the secondary processing tank 32, but uses ceramic balls 39 made of a porous material instead of the laminated plate 36. That is, the inside of the tertiary processing tank 34 is divided into two in the front-rear direction by a partition wall 34a, and a rectangular bucket 38 made of stainless steel wire mesh and containing a ceramic ball 39 as shown in FIG. In the bucket 38, ceramic balls 39 are accommodated in about 40% of the bucket volume, and the remainder is left as a space. Therefore, when the bucket 38 is placed inside the tertiary processing tank 34, as shown in FIG. 4, the area with the ceramic balls 39 and the area 39a without the ceramic balls 39 are alternately formed in the vertical direction.

The pores of the ceramic ball 39 are occupied by aerobic microorganisms. The aerobic microorganisms are activated by air floating from the lower air diffusion block, and decompose the contents of wastewater into water and carbon monoxide. I do. Therefore, the precipitation layer 33
When the sewage flows into the tank, it first descends on the front side of the partition wall 34a, then rises on the rear side and proceeds to the subsequent water storage tank 35. Purifying action is performed by the action of aerobic microorganisms. Therefore, compared with the case where the ceramic balls 39 are used for the entire tertiary treatment tank 34, the amount used can be reduced, and the total weight of the purification tank 30 can be reduced. Further, the tertiary treatment tank 34 is divided into two tanks before and after the partition wall 34a, and the sewage flows in series. Therefore, the flow path becomes long, a sufficient purification time is obtained, and the effluent containing no sewage composition becomes the next effluent. It flows to the water storage tank 35.

Reference numeral 71 denotes a drain pipe for discharging the treated water in the water storage tank 35 to the outside so as not to exceed a predetermined water level WL.
As described above, since the septic tank 30 has the primary treatment tank 31 adjacent to the toilet unit 40, the relatively poorly flowable sewage generated in the toilet unit 40 is pumped to the septic tank 30 with the shortest pipe length. And the likelihood of clogging the sewage pipe 62 is reduced.

The toilet unit 40 is divided into a front male unit 42 and a rear female unit 43 by a partition wall 41 extending in the left-right direction of the vehicle. Unit 4 for men
2 is provided with a pair of urinals and toilets, and the female unit 43 is provided with two pairs of toilets. Each unit 42, 43 is provided with a pair of a hand-washing machine 44 and a washing mirror 45. Reference numeral 46 denotes a detachable staircase, and reference numeral 47 denotes an opening / closing door. An independent pair is prepared for the male unit 42 and the female unit 43, respectively. 48 is a skylight. As described above, since the partition 41 is a high wall reaching the ceiling, the male unit 42 and the female unit 43 are completely shut off, and the voice is not transmitted, so that the female use of the female unit 43 is easy. Will be able to do it.

As shown in FIG. 6, the sewage pump unit 50 is connected to each toilet B of the lavatory unit 40 by a sewage pipe 61, and is connected to the wastewater discharged therefrom and the treated water used to wash them. Collect the liquid mixture once. There, a solid is finely crushed by a rotary blade (not shown) to improve the fluidity, and when the inside exceeds a predetermined water level, the solid is pressure-fed to the purification tank 30 through the sewage pipe 62 by a built-in pump. In this embodiment, the sewage pipe 62 is constituted by two juxtaposed pipes, and even if filth may be clogged in the pipe, the clogged pipe is used as a bypass so as not to cause any trouble. You can do it. The sewage sent to the septic tank 30 flows through the tank sequentially and is subjected to a purification treatment, and the organic matter is removed through the above-described process, and is stored in the water tank 35 as decolorized and deodorized treated water.

When the toilet unit 40 is in use, the treated water is pumped to each toilet B by the water supply pump 64 through the sink pipe 63, and after the toilet, the toilet B is washed and sent to the lower sewage pump unit 50 below. Runs down by gravity. The purification process of the sewage in the septic tank 30 can be advanced even when the toilet unit 40 is not in use, such as when moving. That is, the purification tank 30 is provided with a circulation pipe 65 that connects the inside of the water storage tank 35 to the inside of the primary treatment tank 31, and a part of the treated water is primarily removed by the circulation pump 66 while the use of the toilet unit 40 is suspended. The wastewater is refluxed to the treatment tank 31 so that the sewage does not stay in the clarification tank 30 so that the decomposition of the organic matter in the sewage is continued.

A small circulation pipe 67 for connecting a pipe downstream of the circulation pump 66 of the circulation pipe 65 into the water storage tank 35 is provided in a branched manner. The small circulation pipe 67 has activated carbon 68 contained in a container. Is interposed. A switching valve 69 selectively connects the downstream side of the circulation pump 66 to the circulation pipe 65 and the small circulation pipe 67. When the switching valve 69 connects the circulation pump 66 to the circulation pipe 65, the treated water is recirculated from the water storage tank 35 to the primary treatment tank 31, and when the switching valve 69 is connected to the small circulation pipe 67, the treated water in the water storage tank 35 After passing through the activated carbon 68, it is deodorized and decolored, and is returned to the water storage tank 35 again. Thus, when the use of the toilet unit 40 is suspended, if the switching valve 69 is switched to the circulation pipe 65, the sewage in the septic tank is sequentially purified, and eventually the entire amount becomes treated water.
When the use is suspended for a long period of time, it can be discharged to the outside sewer or road gutter.

[0017]

As described above, according to the invention of claim 1 of the present application, as a result of the center of gravity moving forward, the running stability is reduced even when the septic tank moves in use with water filled. Less is needed. In addition, the portion protruding rearward from the rear wheel of the carrier, so-called overhang, can be increased,
The processing capacity can be increased by increasing the size of the toilet unit. According to the second aspect of the present invention, since the distance between the toilet unit and the treatment tank of the septic tank is short, the problem that the low-flow sewage discharged from the toilet unit is clogged in the piping is eliminated. In addition, since the water storage tank in the septic tank approaches the machine room, a short piping for deodorizing and decolorizing the treated water is sufficient, and water can be efficiently sent to a distant toilet unit.
