Description

[Detailed Description of the Invention] This invention relates to a switching type waste treatment device that can freely switch between a purification type and a vertical flow type, and is mainly used in vehicles such as railways.

For example, in the treatment of waste from railway vehicles, it is hygienic to use a purification type filter, but ground equipment is required to incinerate the cassette filter filled with waste.

On the other hand, if a vertical flow type is adopted, such equipment is unnecessary, but it is not sanitary.

Therefore, the purification method, which requires above-ground equipment, will not be adopted on all lines, and as long as above-ground equipment is fully equipped, the purification method and the vertical flow method will be used together.

Therefore, if a vehicle equipped with a purification-type filth treatment device is transferred to a line section without ground facilities, the existing toilet cannot be used as it is, so the existing treatment device must be removed and a droop-type one installed. The same was true in the opposite case.

In addition, because such switching work is required, it is not only difficult to relocate vehicles and make effective use of the vehicles. Since it is necessary to prepare, there is a drawback that it is not possible to change the vertical flow type waste treatment to a purification type in a flexible plan.

This invention provides a filth treatment device that includes a filter, a dish-shaped storage box lid provided with an appropriate protrusion for placing the filter, a spiral-shaped storage box that stores a filter medium and fits into the lid;
A cassette type in which dish-shaped water collection trays each having an appropriate protrusion for placing the storage box are stacked one after another, one end of the storage box communicates with the lid, and the other end communicates with the water collection tray. A purification type passage constituted by a filter and an inflow port is removably constructed between the sink pipe holder of the toilet bowl and the disinfection tank, and a vertical flow passage constituted by a vertical flow pipe is installed between the sink pipe holder and the disinfection tank. It is an object of the present invention to provide a switching type filth treatment device which is configured to be detachably attached to a through hole and which eliminates the above drawbacks by allowing the purification type passage and the vertical flow type passage to be mutually switched.

To explain the embodiment shown in the drawings, reference numeral 1 denotes a filter cloth (filter) made of polyolefin fiber, which is a cylinder with an open top surface.

Reference numeral 2 designates a dish-shaped storage box lid which is provided with protrusions 3 on which the filter cloth is placed at appropriate locations (in this example, 6 radially), and is made of polyolefin resin, and the dish-shaped part 4 serves as a sewage receptacle. ing.

Reference numeral 5 denotes a spiral storage box containing a filter material (activated carbon in this example) 6, which is made of polyolefin resin and is fitted into the lid 2.

Reference numeral 7 denotes a dish-shaped water collection tray having protrusions 8 on which the storage box 5 is placed at appropriate locations (in this example, 6 radially), and is made of polyolefin resin.

The water collection receiver 7 collects filtrate (overflow water) which has only passed through the filter cloth 1 and has not been treated with activated carbon at the outermost receiver part 9.
The activated carbon-treated filtrate is collected in the inner receiving part 10 which is sunk in one step.

A hole 11 communicating with the lid body 2 is opened at the outermost end of the storage box, and a hole 12 communicating with the water collection receiver 7 is opened at the innermost end.
is opened.

Reference numeral 13 denotes a tapered resin on-off valve, which is provided in the central opening 14 of the water collection receiver 7, and is urged in the direction of the opening 14 by a spring 15.

The spring 15 is made of resin.

16 is a cover made of waterproof kraft paper, and 17 is a top plate made of waterproof veneer.

The cassette type filter 18, which is constructed by laminating and appropriately combining the above members, is placed on a push-up plate 19 that is urged upward by a spring 20.

Reference numeral 21 denotes an inflow port, which has a large circular inlet 22 and a small circular outflow pipe 23 communicating with each other through a passageway 24, and a push-up body 25 of the on-off valve 13 is protruded from the center of the inlet 22. be.

Reference numeral 26 designates a mounting seat for the inflow account which is detachable with a bolt 27 and closes the through hole 29 of the disinfection tank 28.

The sterilization tank 28 is a donut-shaped tank with an opening in a part of the upper surface so that it can be fitted to the outflow pipe 23 of the inflow account 21 via an O-ring, and a through hole 29 in the center.
is formed so that the vertical flow tube 30 can be inserted thereinto.

The vertical flow pipe 30 is a cylinder with open upper and lower surfaces, and is made of metal, resin, waterproof paper, etc. When using this device in a vertical flow type, the cassette type filter 18 and the inflow port 21 are removed. Cassette type filter holding lid 31.3
2 and a disinfection tank 28.

32 is a sink pipe, 33 is a sink pipe holder, 34 is a toilet bowl, and 35 is a detachable screw.

Next, the operation of this invention will be explained.

When using this device as a purification type, turn the attachment/detachment screw 35 to raise the holding lid 31, and then
The outflow pipe 23 of No. 1 is fitted into the sterilization tank 28, and the cassette type filter 18 is set, and the cassette type filter 18 is held down and fixed with the holding lid 31.

Then, the push-up body 25 of the inflow port 21 pushes up the on-off valve 13 of the cassette type filter 18, so that a gap 14' is formed in the central opening 14 of the water collection receiver 7.

When the toilet bowl 34 is used, the solid matter in the stool is filtered out by the filter cloth 1, and the sewage flows into the storage box 5 from the hole 11 and collects in the spiral-shaped filter chamber. 6 and flows out into the water collection receiver 7 through the hole 12.

This filtered water flows into the inflow account 21 through the gap 14';
It flows out from the outflow pipe 23 into the disinfection tank 28 .

In the above, in order to prevent the toilet from becoming unusable due to the activated carbon 6 in the storage box 5 freezing, wastewater may overflow from the filter cloth 1; This sewage flows out into the disinfection tank 28 following the above-mentioned paths.

Next, when switching this device to the perpendicular type, rotate the attachment/detachment screw 35 to raise the presser cover 31, and the spring 2
Since the push-up plate 19 is pushed up by the force of 0, remove the cassette-type filter 18, remove the bolt 27, remove the inflow account 21, fit the vertical flow pipe 30 in place of the cassette-type filter 18, and remove it. The holding lid 31 may be lowered using the screw 35 and inserted into the through hole 29 of the disinfection tank 28.

Therefore, there is no need to remove the entire device.

In such a case, the toilet bowl 34 passes through the sink pipe 32 and is discharged from the vertical flow pipe 30 to the outside of the vehicle.

In addition, if feces accumulate in the cassette type filter 18 when using the purification type, the cassette type filter 18 can be removed by the above-mentioned procedure and used in the vertical flow type, where it can be incinerated as is. Even if the vertical flow pipe 30 is made of paper, it can be incinerated at the time of switching, which is sanitary.

As described above, this invention has the effect that switching between the purification type and the vertical flow type can be performed hygienically, extremely easily, and quickly by a simple operation.

Therefore, when this device is used in a railway vehicle,
The filth treatment equipment can be easily and quickly switched between the purification type and the vertical flow type, making it possible to make effective use of vehicles and reduce labor costs.Also, since the equipment can be installed on the vehicle before ground equipment is installed, This has the effect of allowing flexible planning of equipment.
