Description

[Detailed Description of the Invention] The present invention is applicable to buildings where sewerage facilities are not sufficiently installed.
Or it relates to an excrement treatment device attached to a ship, vehicle, etc.

Conventionally, in this kind of excrement treatment device, the excrement and urine excreted into the toilet bowl are introduced into the tank as a cleaning liquid, and the cleaning liquid and the excrement are separated in the tank, and the cleaning liquid is supplied to the toilet bowl again and the excrement is introduced into the tank. A so-called circulating water treatment method is well known, in which excrement is sent to a storage tank, but since a pump is used to send the waste to the storage tank, the equipment becomes large and costly (not only does it require a large amount of equipment, but it also increases costs). Pump piping is easily clogged, often rendering the toilet unusable. Moreover, since the pump is installed underground along with the piping, it is extremely difficult to repair it if it breaks down.

In addition, in order to separate the washing liquid that flows into the tank together with the excrement from the excrement, special chemicals are used or differences in specific gravity are used, but it is difficult to create a separated liquid that can be immediately reused. There were drawbacks such as:

In order to eliminate such drawbacks, the present invention opens the excrement discharge pipe of the toilet bowl into a separated washing liquid at an appropriate height that floats and accumulates above the excrement in a sealed tank, thereby sealing the excrement from the toilet bowl. The separated washing liquid is introduced into a predetermined part of the excrement accumulation part in the tank, and the separated washing liquid that is constantly floating and accumulating above the excrement in the closed tank can be supplied into the toilet bowl by a pump,
Furthermore, the inside of the upper end of the sealed tank is connected to a compressed air supply source.
The present invention provides an excrement treatment device characterized in that the excrement is forced into a storage tank through a lead-out pipe from the bottom of the tank by pressurizing the surface of the separated washing liquid by supplying compressed air. .

To explain an embodiment of the present invention with reference to the drawings, reference numeral 1 denotes a pressurized sealed tank having a structure in which the upper surface and outer peripheral wall surface are hermetically closed, the bottom of which is formed in the shape of an inverted truncated cone, and the lower end of the bottom and the excrement It is connected and communicated with the storage tank 2 through an outlet pipe 3.

The outlet pipe 3 is bent in a U-shape from the bottom of the sealed tank 1 and extends upward, and the upper part thereof is bent in an inverted U-shape to communicate with the inside of the upper end of the storage tank 2, thereby removing excrement (feces and urine) 4. The outlet pipe 3 is always filled with the liquid from the center of the closed tank 1, and the storage tank 2 is disposed at an appropriate position on one side of the closed tank 1.

5 is a liquid paraffin-based separation washing liquid (product name Nismoil P)
-70), which has an extremely lighter specific gravity than the excrement, does not react with the components of the excrement, and is easily separated from the excrement. It floats up to a certain amount and accumulates.

Reference numeral 6 denotes a toilet bowl disposed above the sealed tank 1. The excrement discharge pipe 7 connected to the lower end of the toilet bowl is passed through the upper wall of the sealed tank 1 in an airtight manner and introduced into the tank, and the lower end is connected to the separated washing liquid. It is immersed therein so that the opening 7a faces the interface with the excrement 4 at the lower end of the separation washing liquid 5.

8 is a float valve installed inside the discharge pipe introduced into the separated washing liquid 5, and in the normal state when floating above the separated washing liquid 5, the valve seat 9
It is closed and close to the

Reference numeral 10 denotes a suction pipe whose upper end is connected to the suction side of a pump 11 installed at a suitable place on the floor surface, and whose lower end is arranged in the separated washing liquid 5 in the sealed tank 1 so as to surround the lower end. A filter 12 is provided, and the separation washing liquid is opened through the filter 12.

Further, a drain pipe 13 is connected to the discharge side of the pump 11, and the drain pipe 13 is communicated with the inner surface of the toilet bowl 6.

Reference numeral 14 denotes a compressed air supply source such as a compressor or a compressed pump placed at an appropriate location on the floor surface, and the tip opening of the air pipe 15 is placed under the inner surface of the earthen wall of the closed tank 1 to separate it from the inner surface of the upper wall. Compressed air is sent into the space 16 between the liquid levels.

17 is an exhaust pipe connected to the earthen wall of the sealed tank 1, and is equipped with a solenoid valve 18.
When the compressed air supply source 14 such as the compressor is in operation, the exhaust pipe 17 is closed, but normally it is open.

Reference numeral 19 denotes an upper sensor whose detection part is disposed close to the surface of the separated washing liquid in the normal state, and when the detection part comes into contact with the separated washing liquid due to the rise of the separated washing liquid 5, the solenoid valve 1
8 is closed and the compressed air supply source 14 is operated for a certain period of time.

Reference numeral 20 denotes a lower sensor whose detection part is disposed in the liquid appropriately below the liquid level of the separated washing liquid 5, and when the liquid level reaches the sensor 5, the operation of the compressed air supply source 14 is stopped. be.

Reference numeral 21 denotes a pump activation button or lever, which is provided near the toilet bowl 6.

22 is a timer that operates the pump 11 for a certain period of time.

To describe the usage and operation of the excrement treatment device configured as described above, if you operate the button or lever 21 after excreting excrement, urine, etc. into the toilet bowl 6, the pump 11 will operate for a certain period of time and the closed tank will be closed. A certain amount of the separated washing liquid 5 in the toilet bowl 6 is sucked up through the suction pipe 10, and is forced into the toilet bowl 6 through the drainage pipe 13, and the excrement in the toilet bowl 6 is passed through the discharge pipe 7 and passed through the float valve 8.
is pushed down to allow the separated washing liquid to flow out into the lower layer of the sealed tank 1.

The excrement that has flowed into the lower layer of the separated washing liquid in the sealed tank 1 is immediately separated from the washing liquid and deposited on the excrement in the tank 1.
The separated washing liquid is combined with the washing liquid 5 in the tank 1 and reused.

In this way, as the tank 1 is used many times, the amount of excrement 4 in the tank 1 gradually increases and the washing liquid level rises. When the liquid level reaches the upper sensor 19, the upper sensor 19 When this is detected, the solenoid valve 18 of the exhaust pipe 17 is activated to close the limb pipe, and the compressed air supply source 14 such as a compressor is activated to forcefully send compressed air to the upper end space 16 in the tank 1 for cleaning. The liquid level is pressurized to flow the excrement 4 filling the outlet pipe 3 from the lower part of the tank, and a part of it is sent out from the outlet pipe 3 into the storage tank '2.

As a result, the washing liquid level drops due to the pressurization, and the lower sensor 20
When the level reaches the lower sensor 20, it is sensed by the sensor 20 and the operation of the compressed air supply source 14 is stopped, the pulp 18 is opened, and from the state where the washing liquid level has descended to the lower sensor 20, the circuit is opened again due to the collection of excrement. It is something to do.

Note that a sensing mechanism other than the sensor may be used to sense the upper and lower limits of the washing liquid surface.

As described above, the present invention connects and communicates the bottom of a sealed tank whose top surface and surrounding wall surface are airtightly closed with an excrement storage tank via an excrement outlet pipe, and also provides a toilet bowl above the sealed tank. Then, the excrement discharge pipe of the toilet bowl is opened into the separated washing liquid that floats and accumulates above the excrement in the pressurized sealed tank, and a fixed amount of this separated washing liquid can be supplied into the toilet bowl by a pump, and the water is heated. Excretion characterized in that the excrement in the sealed tank is forcibly discharged into the excrement storage tank via the outlet pipe by supplying compressed air into the pressure-tight tank and pressurizing the separated washing liquid surface. Since it is related to waste treatment equipment, the compressed air supply source can be placed at an appropriate location on the floor regardless of underground pipes, so it is suitable for this type of excrement treatment equipment where equipment area is limited. In addition, in the case of conventional direct-type toilets, the excrement storage tank must be installed below the toilet bowl, which not only makes it difficult to pump up and dispose of excrement from the storage tank, but also limits the installation location. However, in the present invention, a sealed tank is provided below the toilet bowl, and a storage tank is provided through a lead-out pipe from the sealed tank, so that the storage tank can be easily installed and placed in a place where excrement can be easily disposed of. It is something that can be done.

Furthermore, the present invention is configured such that compressed air is supplied into the sealed tank to pressurize the surface of the separated washing liquid above the excrement in the tank, and then discharged from the bottom of the tank through the outlet pipe into the storage tank. Compared to the conventional pump system, it is possible to flow smoothly and reliably through the outlet pipe, and maintenance and inspection are also easier.Furthermore, the toilet bowl's waste discharge pipe is inserted into the separated washing liquid in the sealed tank. The excrement that is discharged into the tank together with the washing liquid is separated from the washing liquid below the discharge pipe and is immediately deposited on the excrement in the tank without being mixed into the washing liquid layer in the tank, which scatters in all directions. This means that clean flushing fluid can always be supplied back into the toilet bowl by the pump.
