Description

M256887 IV. Creation Instructions (1) [Technical Field to which the New Type belongs] This creation is to provide a septic tank structure improvement, especially a septic tank design for treating general domestic sewage. [Previous technology] According to my daily discharge of sewage mainly consisting of faeces, the sewage in the living is generally treated by flowing into the septic tank underground of the residence first, so that the clarified wastewater obtained by decomposing and purifying the septic tank, and then The drainage pipe is discharged into the adjacent drainage channel to avoid pollution and drinking water and damage to the ecological environment, and then flows into the septic tank to decompose, and the sludge is accumulated to a certain degree and then extracted and removed. In order to make the discharged wastewater have a proper purification effect, the septic tank is generally separated from a single septic tank into a multi-slot chamber structure, that is, a so-called decomposition tank, The filter tank and the sedimentation tank d [are the chambers. Among them, sewage is connected at a higher position on the first isolation tank, and a waste water discharge pipe is connected at a lower position of the second isolation tank. The feces are broken up to accelerate decomposition; when excrement and / or water can enter the hydrazine to separate, precipitate and purify it, after that: you can first use the septic tank to decompose the single septic tank through the decomposition tank and Shendian tank:? Or: The discharge pipe discharges. It can make the discharged waste water ί: t separated into the structure of the tank chamber, although the structure of the tank chamber will cause chemical precipitation: but also because this kind of septic tank is easy to be blocked or 4 = The volume inside the tank is reduced, which in turn leads to the structure of the septic tank. As a result, the use of multiple tank chambers is hindered, which is not conducive to the agitator. It ’s also causing the feces to break up to speed up the analysis.

M256887 4. Creation instructions (2) Therefore, there should be a septic tank with a different structure. 1 It can improve the lack of the volume of the conventional septic tank structure, and it must be able to form a space for helmet obstacles to facilitate the mixer. Install and make sure that the wastewater purified by decomposition and precipitation in the septic tank can be smoothly discharged to improve the efficiency of the overall septic tank. [New content] In view of this, the creator carefully researched, analyzed, and designed. After actual experiments and multiple improvements, this creation has been created today; the main purpose of this creation is to provide a siphon with a siphon. The septic tank structure of the functioning discharge pipe can smoothly discharge the purified and dischargeable wastewater located on the sedimentation area in the septic tank to improve the efficiency of the overall septic tank.丨 験 The second purpose of this creation is to provide a septic tank structure without a separation tank, which can effectively increase the volume of the septic tank and accelerate the decomposition and sedimentation speed of sewage. Another object of this creation is to provide a septic tank structure with a barrier-free space to facilitate the design of the agitator and improve the efficiency of accelerated decomposition of feces.

This creation is a specific structure and technical means to achieve the above purpose. It mainly includes a septic tank without an internal compartment. The septic tank has an inlet to provide a sewage inlet pipe connection. A slightly lower position of the inlet has an outlet for providing a discharge pipe installation. The discharge pipe has an inner section which slopes downwardly into the septic tank, and a circle of a plurality of holes is provided at the lower part of the inner section. The water suction part enables the purified wastewater located on the sedimentation area in the septic tank to be sucked out and discharged through the water suction part, and an obstacle-free space without a partition is formed in the septic tank to effectively improve the septic tank. The volume of the tank

The exemplary embodiment of the present invention and the further description with reference to the accompanying drawings are only for the purpose of making the discussion of this creation more comprehensible. : Γ = Beyond the scope of this creation, for those skilled in the art, it is conceivable to implement, change, modify and equivalent implementation content. Please refer to the first and second pictures shown in the picture. This creative system provides a chemical tank m 'structure that can effectively increase the volume of the chemical tank tank, including a septic tank and a tank for discharging the chemical tank. The septic tank trough 1 is a drainage pipe 2 which can be discharged by 7 knives to dissolve sediment. The septic tank trough i is mostly a closed trough with no internal compartment and sufficient depth. An inlet is provided at the top for providing connection of the sewage introduction pipe 13 so that the general domestic sewage or excrement flushed from the toilet can enter the septic tank 1 through the inlet and be on the other side away from the inlet. In addition, an outlet 丨 2 is provided at a position slightly lower than the inlet 11 (about 2 inches lower) so that the discharge pipe 2 can be installed. The above-mentioned discharge pipe 2 has a pipe body 21 that can be inserted into the outlet 12 of the septic tank and an inner section 22 that slopes downwardly into the septic tank. The inner section 22 is essentially the discharge pipe 2 inserted in The extension of the inner end of the pipe body 21 of the outlet 12 is sloping downwards between about 30 and 60 degrees, and is the best length in the picture, and its mouth 2 21 is closed and is in the inner section. The lower part of 2 2 is slightly lower than the horizontal plane of exit 12 (about 6 inches to 8 inches lower)

M256887 4. Creation instructions (4) A water absorption part 2 2 2 is provided with a plurality of holes 2 2 3 around it, so that waste water that can be discharged by decomposition and sedimentation in the septic tank 1 will pass through the holes 2 2 3 of the water absorption part 222 It's not out. Please refer to the second figure, which shows that the general domestic sewage or excrement from the toilet is introduced into the septic tank 1 through the inlet 11. The decomposed and degraded sewage will settle to the bottom of the pond to form silt to define a sedimentation area 1 4. On the sedimentation area 丨 4 is a relatively clear wastewater area 15 that has met the discharge standard through decomposition and purification, and light suspended solids will float on the upper layer to define a suspension area 16. In terms of a general septic tank, the waste water zone 15 containing a large amount of fresh water purified by decomposition is in a range of about 6 inches below the suspension zone 16. The septic tank formed in accordance with this creative structure, wherein the inner section 22 of the discharge pipe 2 extends into the waste water area 15 of the septic tank tank 1 at a predetermined downward angle, and is opposite to the inner section 22 A water absorption part 222 with a plurality of holes 223 around it is provided in the 15th section of the waste water area. As a result, once sewage or toilet flushed excrement is introduced into the septic tank i through the inlet 11, the purified dischargeable wastewater located in the wastewater area 15 will be sucked out through the hole 223 of the water absorption part 222 And outward. This is because when the amount of liquid accumulated in the septic tank 1 increases, the water in the septic tank 1 will be driven to balance the water pressure. Therefore, each time sewage is introduced from the inlet 11 to make the water level When the height exceeds the position of the outlet 丨 2, the hole 223 in the water suction portion 222 of the discharge pipe 2 will have a siphon effect, so that the waste water in the waste water area 15 is quickly sucked into the discharge pipe 2 and discharged. In addition, because the port 221 of the inner section 22 and the pipe wall about 6 inches to 8 inches away from the horizontal surface of the outlet 12 are closed, it will not discharge unpurified wastewater or dirt. At the same time, the septic tank formed according to this creative structure will make the septic tank
