Description

[Detailed Description of the Invention] <Industrial Application Field> The present invention relates to a sewage discharge treatment device in which sewage generated in facilities such as hospitals and special nursing homes is transported in a toilet tank and sucked into an outdoor suction machine. It is something.

<Conventional technology> Conventionally used sewage treatment for a sewage tank serving as a toilet tank for a nursing bed with a toilet bowl a involves carrying the sewage tank in a hand-down position to the sewage room, fully opening the top cover C, and then opening the other side. The sewage was simply dumped into a separate sewage container d while pulling up the bottom of the sewage tank by hand (see Figure 3 A, B, and C).

<Problems to be Solved by the Invention> However, in the case of current general facilities, the distance from the hospital or living room to the waste room is 5 to 40 meters.

Therefore, the caregiver must use a heavy sewage tank (10 to 1.5
kg) by hand and carrying one tank or two at a time, which meant that in facilities with many bedridden patients, the work had to be carried many times.

In addition, as mentioned above, when dumping sewage in a sewage room, the bottom of the sewage tank is pulled up, so it is necessary to visually observe the state of the sewage falling so that the sewage does not fly out of the container. Unable to avoid strong odors, caregivers have to endure heavy, ugly, and painful odors.

In view of the above-mentioned circumstances, it is an object of the present invention to provide a sewage discharge treatment device that solves the above-mentioned problems by forcibly sucking sewage through a suction pipe of a suction machine installed outdoors. .

Means for Solving the Problems> The present invention provides a sewage discharge treatment device for discharging sewage in a sewage tank outdoors, which includes a drainage tank installed outdoors, a suction device installed in the drainage tank, and a suction device installed in the drainage tank. It is equipped with a water suction pipe that sucks the sewage in the sewage tank into the drainage tank by operating a suction machine.

<Function> Due to the above structure, the sewage tank installed at the bottom of the bed is placed on a trolley, pulled into the end of the building, and transported to the position of the protruding suction pipe, and the suction pipe nozzle is inserted into the sewage tank. In this state, if you operate a suction machine that acts as a vacuum pump inside the drainage tank installed outdoors and apply suction to the suction pipe whose tip faces the drainage tank, the sewage in the sewage tank will be forcibly sucked out. It can be discharged into a wastewater tank.

<Example> Hereinafter, an example of the present invention will be described based on the drawings.

Figure 1 shows an embodiment in which a sewage tank that is transported is directly treated. 1 is a bucket-shaped sewage tank that serves as a toilet tank that is carried out from the bottom of bed a. A plurality of sewage tanks 1 are mounted on a trolley 3. It is placed and transported. Reference numeral 4 denotes a drainage tank to be installed outdoors, and a suction machine 6 serving as a vacuum pump is attached to the top of this drainage tank 4. An L-shaped water intake pipe 5 facing into the building is connected to the tip of the bellows-type flexible pipe 10 fixed to the upper part of the drainage tank 4.
Connect it. This water suction pipe 5 is suspended by a holder 13 and a hanging rod 14 attached to the outer wall 12 of the building, and a handle 15 is provided near the tip of the water suction pipe 5, and an inward opening valve 9 is provided at the end position in the drain tank 4. will be established.

Next, to explain this effect, first, the sewage tank l removed from the nursing care bed is placed on the trolley 3, transported to the water suction pipe 5 position at the end of the building, and stopped, and the L-shaped tip nozzle 5a of the water suction pipe 5 is Insert into sewage tank 1.

At this time, the suction device 6 is appropriately driven and the air in the drain tank 4 is discharged from the water type deodorizing tank 8 to the outside via the activated carbon deodorizing tank 7 by the suction force generated by the vacuum. Along with this, the valve 9 at the end of the water suction pipe 5 opens inward, the air pressure inside the water suction pipe 5 drops rapidly, and at the same time the valve 22 provided in the connection box 23 connected to the lower part of the drain tank 4 is closed. The suction force is concentrated all at once on the tip nozzle 5a of the water suction pipe 5, and the sewage and filth in the sewage tank 1 are sucked into the water suction pipe 5, and the bellows-type bending pipe 10. It is sent into the drainage tank 4 through the valve 9. In this case, the water suction pipe 5 swings vertically and horizontally around the universal joint 11, and has a flexible pipe 1 at the base.
0, so when inserting it into the sewage tank 1 by grasping the handle 15 at the tip and operating it appropriately, the movement within this operating range will be transmitted to the bending/extending tube 10 like a seesaw, but the bending/extending tube 10 will absorb the size. I can do it. In addition, the sewage collected in the drainage tank 4.

Sewage will be discharged through the existing septic tank (not shown).

In addition, a special cleaning device is used to remove the dirty water that adheres to and remains on the outside and inside of the tip nozzle 5a of the water suction pipe 5 and the inner surface of the flexible pipe 10. That is, as shown in FIG.
The water washer 16, the fixed shower nozzle 17, the water level sensor 18, the water tank 19, and the water supply 20. It consists of a sewer system 21.

When cleaning the inner and outer surfaces of the nozzle 5a, the suction device 6 serving as a vacuum pump is operated, the nozzle 5a is placed in the washer 16, and a shower from the shower nozzle 17 is sprayed onto the entire outer surface of the nozzle 5a. Thus, the dirt on the outer surface of the nozzle 5a is washed away by the fountain and enters the washer 16. This nozzle 5a absorbs dirt together with the water in the washer 16, and since this water also passes through the inner surface of the flexible pipe 10, it also washes away dirt from the flexible pipe 10 and sends it to the drainage tank 4. Furthermore, when the water in the washer 16 decreases and the water level drops, the water surface sensor 18 detects this, drops new water in the water tank 19, and the tip nozzle 5a absorbs water again, causing its own inner surface to flow.
Finish cleaning by rinsing the outer surface.

In addition, when suctioning sewage and filth, when the suction device 6 sucks out the air in the drain tank 4, the vertically suspended valve 22 closes due to its own weight, and the upper part of the drain tank 4 is closed. Since the valve 9 located in the water intake pipe 5 is sucked inward, it becomes open.
Sewage and filth that have passed through the flexible pipe 10 are guided into the drainage tank 4. Further, since the tip nozzle 5a of the water suction pipe 5 is always in a vertical or nearly vertical position, dirt is less likely to adhere or remain there than in a flat state, and it is easier to wash off.

<Effects of the Invention> As described above, the sewage discharge treatment device of the present invention has a water suction pipe protruding from a suction type drainage tank installed outdoors, facing indoors,
The sewage from the sewage tank transported through the water suction pipe is forcibly sucked up, so when dumping T9 materials, the caregiver inserts the nozzle into the mouth of the sewage tank and turns on the suction machine (vacuum pump). The dumping operation can be done easily, eliminating the need for heavy lifting. What's more, the dumping operation can be started simply by inserting the nozzle into the mouth of the sewage tank, so there is no need to fully open the top cover like in conventional bucket-type sewage containers.

Caregivers do not see the sewage or filth, and during the dumping process, the odors from the sewage tank itself do not spread into the room because the dumping power or vacuum pump is used for suction.

In this case, in order to transport multiple sewage tanks (toilet tanks) from the hospital room or living room to the sewage room using a trolley, for example, a sewage tank used for a nursing bed with a toilet bowl can be moved between two sewage tanks.
When a patient finishes their business and calls, another sewage tank can be replaced. Even in facilities with many sad patients and elderly people, multiple sewage tanks can be removed with just one rotation of the trolley. It is convenient to be able to collect and replace the tank.

For example, a ready-made medical bucket has a diameter of 30 cm,
If we put six of these, three in two rows, on a trolley, it would take six people to replace the sewage tank in one round, and the width of the trolley would be just over 60an, so it could be used in each hospital room.

It is now possible to get close to the bed in the living room, and the labor required for caregivers to load, unload, unload, hand-carry, etc. can be significantly reduced. Therefore, the method of dumping and transporting these items is to use existing hospitals.

Even if a facility requires major renovation work, it can be put to practical use simply by adding the device of the present invention.
