Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mobile temporary toilet unit utilizing a vacuum sewage collection system.

[Prior Art] A vacuum wastewater collection system is known as one of the systems for collecting local wastewater. This system consists of a vacuum pumping station for collecting and storing sewage, a vacuum valve for sucking the sewage, and a vacuum sewer pipe connecting the vacuum valve and the vacuum pumping station. Then, the wastewater flows through the vacuum sewer pipe together with air through a vacuum valve as a multiphase flow, and is collected in a water collection tank within the vacuum pumping station.

Mobile temporary tray units using this vacuum wastewater collection system have been put into practical use in the United States, Sweden, and other countries. These include a men's toilet, a women's toilet, a vacuum pump, and a water collection tank room in the same container, and the container is placed on a trolley and loaded onto a trailer (truck).
This is the driving force behind this. When an event or the like was held, a trolley carrying a container was transported to the venue using a trailer (truck), and the container was left there for the duration of the event.

[Problems to be Solved by the Invention] However, in the above unit, all the equipment is housed in the same container, so the size of the container is, for example, 6 to 12 m in length and 2 to 3 in width. .6m.

Therefore, it is too large to be transported due to Japan's traffic and road conditions. In addition, it is not possible to bring equipment into event venues due to site restrictions, and if the event venue is located on a riverbed, slopes make it difficult to bring in equipment.

SUMMARY OF THE INVENTION An object of the present invention is to provide a mobile temporary toilet unit using a vacuum sewage collection system that is easy to transport and can be installed in narrow spaces.

[Means for Solving the Problems] According to the present invention, a water collection tank, a water collection tank/vacuum pump unit equipped with a vacuum pump, etc., a toilet unit equipped with a toilet bowl, a vacuum valve, etc., and a power generation system equipped with a generator. The machine is divided into machine units, and each unit is housed in a compact cargo that can be loaded onto a truck. Here, it is preferable that the truck weighs about 4 tons.

Preferably, a drain pipe equipped with a pressure pump is connected to the water collection tank.

Further, it is preferable that the toilet unit is provided with a drain pipe connected to the toilet bowl and connected to the water collection tank by a hose, and that the drain pipe is provided with a vacuum valve and a water level detection pipe.

Further, it is preferable that the generator unit is provided with a private power generator and connected to a power distribution board provided in the vacuum pump unit and connected to the vacuum pump and the pressure pump via a power cable. However, if power can be supplied from outside, the generator unit can be omitted.

[Operations] In the mobile temporary toilet unit using the vacuum sewage collection system configured as described above, the cargo of each unit is loaded onto, for example, a 4-ton truck, easily transported to the site, and installed using a vehicle-mounted crane. , connect the toilet unit to the water collection tank with a hose, and connect the private power generator to the power distribution board with a power cable.

During operation, the vacuum pump is activated to maintain a vacuum in the drain pipe through the water collection tank and hose up to the vacuum valve.

When a certain amount of sewage accumulates in the drain pipe on the side of the toilet, the water level detection pipe detects the water level, the vacuum valve opens, and the sewage is sucked into the water collection pipe through the hose. Therefore, when a certain amount of wastewater in the water collection tank reaches a certain level, a pressure pump is activated to force the wastewater to be sent through the drain pipe to the public sewer system, or the wastewater is periodically removed from the water collection tank using a vacuum car.

[Example code] The present invention will be described in detail below with reference to the drawings.

In FIG. 1, the mobile temporary toilet unit according to the present invention includes a water collection tank/vacuum pump unit 11, a men's toilet unit 21, and a men's toilet unit 21, which are housed in cargos 10, 20, 30, and 40, respectively, which can be loaded on a truck of about 4 tons. It consists of a women's toilet unit 31 and a generator unit 41.

The water collection tank/vacuum pump unit 11 is provided with a water collection tank 12 that temporarily stores the collected wastewater.
4 is connected, and also a drain pipe 16 with a pressure pump 15.15. In addition, the symbol 17 in the figure is a switchboard, and the symbol 18 is a discharge port.

The men's toilet unit 21 includes a toilet bowl 22.22.
and a washstand 23a are provided, each of which is connected to the water collection tank 12 via a hose 51 by a drain pipe 23. A vacuum valve 24 and a water level detection pipe 25 are provided in the middle of the drain pipe 23.

The women's toilet unit 31 is configured substantially the same as the men's toilet unit 21 and is connected to the water collection tank 12 by a hose 51.

The generator unit 41 is provided with a private power generator 42, and is connected to the power distribution board 17 of the water collection tank/vacuum pump unit via a power cable 52.

Note that if power can be supplied from the outside, the cargo 40 of the generator unit 41 can be omitted. Also,
In places such as construction sites where only the men's toilet unit 21 is required, the cargo 30 of the women's toilet unit 31 may be omitted, and the quantity of the cargo 20.30 of the toilet unit 21.31 may be changed depending on the scale of the event venue. can be increased.

2 to 4 show an example of the equipment arrangement of the men's toilet unit 21, which includes one toilet bowl 22, three urinals 26, two wash basins 23a, and a mirror 27. It is being In addition, at the entrance of the cargo 20 and the partition wall 20c,
A door 20a120b is provided respectively, and the ceiling is provided with a door 20a120b.
Four frosted glass plates 28 are provided for lighting.

5 and 6 show an example of the equipment arrangement of the women's toilet unit 31, in which two toilet bowls 22 are provided, and the rest is substantially the same as the men's toilet unit 21.

When transporting the temporary toilet unit, as shown in FIGS. 8 and 9, the cargo 1 is loaded onto the loading platforms 61 of four 4-ton trucks 60 by an on-vehicle crane 62 with a working radius R of, for example, 3 m.
Each of the cargoes 0 to 40 is loaded and transported, carried to the site, and the crane 62 lowers and installs the cargoes 10 to 40.

Then, connect the power cable 52 to the switchboard 17, and connect the drain pipes 23, 23 to the water collection tank 12 with the hoses 51, 51.
Connect to.

During operation, the private power generator 42 is activated and power is supplied to the vacuum pump 14.1 via the power cable 52 and the switchboard 17.
4 and pressure pump 15.15. First, the vacuum pumps 14 and 14 are operated to maintain a vacuum in the drain pipe 23 up to the vacuum valve 24 via the water collection tank 12 and the hose 51. When a certain amount of sewage accumulates in the drain pipe 23 on the toilet bowl 22 side, the vacuum valve 24 opens in response to a signal from the water level detection pipe 25 that detects the water level, and the sewage in the drain pipe 23 is sucked into the hose 51. The suctioned wastewater is collected in the water collection tank 12 via the hose 51. When a certain amount of sewage has accumulated in the water collection tank 12, the pressure pump 15.15 is operated to force the sewage to be sent from the drain pipe 16 to the public sewer system, or periodically carried out from the drain port 17a by a vacuum car.

[Effects of the Invention] Since the present invention is configured as described above, it is divided into a water collection tank/vacuum pump unit, a toilet unit, and a generator unit, and is compacted and stored in a cargo for easy transportation. It can be installed in a narrow place.
