Referring to Figures 1 to 7 the operational relationship of the present invention configured as described above is as follows.

First, an embodiment of the present invention will be described with reference to FIGS. 1 to 4.

As shown in FIG. 1, after the toilet is viewed from the toilet 1, when the water lowering button (lever) installed on the toilet or the toilet is operated, the pump 14 is operated and the low specific gravity washing liquid 25 contained in the washing liquid chamber 5 is operated. This is discharged to the toilet (1) through the washing liquid return pipe (15).

At this time, the amount of low specific gravity washing liquid 25 in the washing liquid chamber 5 supplied to the toilet 1 by operating the water down button is enough to send down the manure in the toilet 1 to the manure chamber 4 with l discharge. The amount can be determined by adjusting the time the pump 14 is operated by a timer.

The manure in the toilet 1 is flushed with the low specific gravity wash 25 in the same way that the low specific gravity wash 25 is swept away from the well-known flushing toilet by the water pressure coming down the toilet 1 as described above. Through) enters the manure chamber (4) inside the tank body (3).

The lower end of the inlet pipe 12 is spaced closer to the inner bottom surface of the tank body 3, the manure and the low specific gravity washing liquid 25 is introduced together to the lower side of the tank body (3).

At this time, the manure chamber 4 inside the tank body 3 is contained in the low specific gravity wash 25, and in this state, as the manure is introduced, the manure is reduced by the difference in specific gravity between the manure and the low specific gravity wash 25. ) Sinks downward, and the low specific gravity washing liquid 25 floats to the upper part of the manure 26 so that the lower manure layer and the upper specific gravity washing liquid 25 in the interior space of the manure chamber 4 inside the tank body 3 ) Separated into layers.

As the toilet is continuously used as described above, as the manure and the low nasal wash 25 flow into the manure chamber 4 through the inlet pipe 12, the height of the lower manure 26 layer is gradually increased. Thereby, the height of the low specific gravity washing liquid 25 layer located above the manure layer also becomes high.

When the height of the manure layer and the height of the low specific gravity washing liquid layer 25 are increased, the primary partition wall 7 on one side of the inflow pipe 12 is spaced apart from the inner bottom surface of the tank body 3 at the lower side. As the passage space is formed, and the secondary partition 8 having the upper opening is formed next to the primary partition 7 in a zigzag manner in the vertical direction, the lower manure 26 is shown in FIG. 1. As shown by the arrow of the primary partition (7) through the passage space of the lower side and the secondary partition (8) through the discharge space to be discharged to the manure discharge port (11), the manure discharged to the manure discharge outlet (11) as shown in FIG. As shown in is introduced into the septic tank (9) through the manure discharge pipe (10).

As described above, when the manure 26 under the inflow pipe 12 is discharged to the manure discharge port 11 side through the passage space between the first and second partition walls 7, 8, the secondary of the lower side of the inflow pipe 12 In the lower space between the partition wall 8 and the blocking wall 6, the inclined plate 17 having the lower edge portion on the side of the blocking wall 6 and the lower edge portion on the side of the secondary partition wall 8 has a rounding part 16. As the cover is removed, the angled edge is removed, and the downwardly inclined portion on the blocking wall 6 side and the rounded rounding portion 16 are positioned on the secondary partition wall 8 so that the manure is inclined downwardly and the rounding portion. It is discharged to the manure discharge port 11 beyond the secondary partition 8 without gathering in (16).

In addition, the low specific gravity washing liquid 25 located above the manure 26 layer enters the washing liquid chamber 5 through the screen 13 formed on the upper side of the barrier wall 6 as the height thereof increases.

At this time, when the manure and low specific gravity wash 25 comes down to the manure chamber 4 through the inflow tube 12, the manure and low specific gravity washing liquid 25 is lowered in the lower side of the inflow tube 12, the manure residue screen In consideration of being able to pass through (13), the damper 18 is installed on the front side of the screen 13 at a higher level than the liquid level of the low specific gravity washing liquid 25, so that the manure waste that may be injured upwards is damped. While hitting (18), it is possible to block the passage to the screen (13).

As described above, it is possible to minimize the excretion of the manure residues beyond the screen 13 by the damper 18, but the small manure residues may exceed the screen 13, and the screen 13 together with the low specific gravity washing solution 25. The small manure waste introduced into the washing liquid chamber 5 is caught by the strainer 22 installed in the washing liquid chamber 5, and the low specific gravity washing liquid 25 of the liquid flows through the strainer 22 of the washing liquid chamber 5. Goes down there.

Thus, the low specific gravity washing liquid 25 accumulated in the lower side of the washing liquid chamber 5 sends the low specific gravity washing liquid 25 in the washing liquid chamber 5 to the toilet when the pump 14 is operated using a toilet next time. Sweep into the manure chamber (4).

In addition, in the present invention, the inspection port 19 is provided on the upper surface of the tank body 3 on the upper side of the tank body 3 and the upper side of the manure chamber 4 in which the secondary partition wall 8 is installed. In the case where manure wastes are accumulated in (22) and foreign matter has flowed into the manure chamber (4) above the secondary partition (8), each of the inspection openings (19) can be opened to remove the manure waste and foreign matter. The inside of the tank 2 can be used without clogging.

In addition, since the present invention is mainly installed outdoors, there is a fear that the separation tank (2) and the washing liquid return pipe (15) are frozen in cold weather, the insulating material (23) is installed to be wrapped around the entire outer surface of the separation tank (2) The heating wire 24 is wound around the washing liquid return pipe 15 exposed to the outside of the tank main body 3 so that the separation tank 2 and the washing liquid return pipe 15 can be used without being frozen.

The low specific gravity wash uses vegetable oil having a lower specific gravity than water, such as mineral oil, olive oil, palm oil, soybean oil, coconut oil, and palm oil, and should be employed to have a low volatility and not easily catch fire. It turns out that it is preferable to add and use a pigment | dye and an aromatic agent as needed.

The following is a description of the working relationship for this embodiment shown in Figs. 5 and 6, this embodiment is the same as the one embodiment, but the air pump 28 and the air injection section 29 is added to the configuration of one embodiment As it is installed in the description of the same parts as the embodiment will be omitted, and only the parts added to this embodiment will be described.

That is, when the manure and the low nasal washing liquid 25 is introduced into the manure chamber 4 through the inflow pipe 12, the tissue is also introduced together, and the manure, the resting tissue and the low nasal washing liquid are separated by the specific gravity. Sinks to the lower side and the low specific gravity wash rises to the upper side of the manure layer.

At this time, the amount of the manure is increased by the inclined plate 17 having the rounding part 16, and the manure and the tissue do not collect at the lower edges of the secondary partition 8 and the blocking wall 7 in the manure chamber 4. While the manure is to go beyond the secondary partition (8), the rounding part 16, there is a fear that the wet tissue and the waste and the manure debris accumulated.

Therefore, in this case, when the air generated by the air pump is operated by injecting the air pump 28 to the rounding part 16 through the air injection pipe 29, the rounding is performed by the injection pressure of the air injected through the air injection pipe. The sediment, such as the manure and wet tissues that are accumulated in the wetted part 16 is injured, and the sediment thus injured is discharged to the manure outlet 11 beyond the secondary partition 8 without accumulating on the rounding part 16. will be.

In addition, the following is a description of the working relationship of the third embodiment shown in Figure 7, the working example and the third embodiment is the same, but the only difference is that in this embodiment the manure accumulated on the rounding part 16 is wet An object such as a toilet paper is released to inject air generated in the air pump 28 to rise to the air pressure, the third embodiment is to inject the manure by injecting the manure by the pumping pressure of the submerged pump 30 submerged in the manure.

Therefore, this embodiment differs only in the use of an air pump and an underwater pump, and accordingly, the injection fluid is different according to the difference. In fact, sediment collected in the rounding part and sediment, such as a wet tissue released from the injection fluid, Pushing up to injection pressure is the same.

In this embodiment, the air pump 28 or the submersible pump 30 is operated by installing a control means such as a timer in the air pump 28 or the control device for controlling the submersible pump 30. It can be operated automatically every set time.
