Description

[Detailed description of the invention] [Technical field] This invention relates to the structure of an air jet pipe used in a septic tank, and more specifically, the present invention relates to the structure of an air jet pipe used in a septic tank. Regarding the technique of trying to make it erupt.

[Background Art] Conventionally, a pipe is composed of a vertical pipe 5' and a horizontal pipe 1',
In the case of an inverted T-shaped air jet pipe 3' used as an aeration pipe or a backwash pipe in a septic tank, air is pumped through a vertical pipe 5' and air jet ports 2 are bored in the left and right horizontal pipes 1'. If you want to blow out air evenly from left to right into the septic tank, you can make the air blow out evenly from the left and right air outlets 2' by increasing the pressure by reducing the hole diameter of the air outlets 2'. At this time, the drawback was that the smaller the pore diameter, the easier it was to cause clogging. Particularly in cases such as backwash pipes, which are not normally used but are used only for maintenance every 3 to 4 months, if the pore diameter is small, clogging will almost certainly occur due to adhesion of microorganisms, etc. In addition, when the hole diameter is made larger to prevent clogging, air can be easily ejected from the air outlet 2' near the vertical pipe 5' with less pressure loss, and if the horizontal pipe 1' is not horizontal on the left and right This had a drawback in that air was ejected only from the air ejection port 2' of the horizontal pipe 1' on the upward side.

[Purpose of the invention] The present invention has been made in view of the points mentioned above, and the purpose of the invention is to create an air ejection pipe that has a well-balanced air ejection from the left and right horizontal pipes and is less prone to clogging. It is on offer.

[Disclosure of the invention] The air jet pipe of the septic tank of the present invention is in an inverted T-shape, and the air jet pipe 3 has an air jet port 2 for jetting air in the horizontal pipe 1. A partition plate 4 that partitions the left and right sides is vertically installed from the horizontal pipe 1 to the vertical pipe 5, and by configuring it as described above, the drawbacks of the conventional example are solved. In other words, with the above configuration, the air sent from the vertical pipe 5 is divided into two parts by the partition plate 4 and is sent equally to the left and right horizontal pipes 1, so that the horizontal pipe 1 is not horizontal to some extent. Even if the holes are perfect or the hole diameters of the air jet ports 2 are different on the left and right sides, air can be jetted into the septic tank from the left and right horizontal pipes 1 in a well-balanced manner.

The present invention will be explained in detail below using examples.

As shown in Fig. 1, the air jet pipe 3 used as an aeration pipe or backwash pipe in a septic tank is mainly composed of a vertical pipe 5 and a horizontal pipe 1, and the right horizontal pipe is connected to an inverted T-shaped joint 6. 1a, left horizontal pipe 1b, and vertical pipe 5 are inserted to form an inverted T-shape. The right horizontal pipe 1a and the left horizontal pipe 1b are each provided with a plurality of air ejection ports 2 for ejecting air. Air jet pipe 3
A partition plate 4 is vertically disposed inside the air jet tube 3 from the horizontal tube 1 side to the vertical tube 5 side so as to partition the inside of the air jet tube 3 into left and right sides. At this time, the partition plate 4 is
It is vertically installed inside the air jet pipe 3 so as to be located in the center of the air jet pipe 3. With the above configuration, the air sent to the horizontal pipe 1 through the vertical pipe 5 in order to blow air into the septic tank is divided into two parts by the partition plate 4 vertically installed inside the air jet pipe 3. and is sent equally to the left and right horizontal pipes 1. Therefore, even if the left and right horizontal pipes 1 are somewhat imperfectly level, air will not be blown into the septic tank only from the horizontal pipe 1 on the upward side, and the air in the horizontal pipe 1 will not be blown into the septic tank. Even if the diameter of the hole in the outlet 2 is set to be different on the left and right sides, the air is divided into two by the partition plate 4 and sent to the horizontal pipe 1 equally on the left and right sides.
Air can be blown out into the septic tank from the left and right horizontal pipes 1 in a well-balanced manner.

In addition, in the embodiment described above, the air jet pipe 3 has an inverted T shape.
Although the case of a T-shape is shown, the same effect as the above-mentioned embodiment can be obtained even if it is a T-shape.

[Effect of the invention] As described above, in this invention, a partition plate is vertically installed inside the air jet pipe to partition the inside of the air jet pipe into left and right sides from the horizontal pipe to the vertical pipe, so that air can be jetted into the septic tank. The air sent through the vertical pipe is divided into two parts by a partition plate and sent equally to the left and right horizontal pipes, which may cause the horizontal pipe to be somewhat imperfectly leveled or due to the hole diameter of the air outlet. Even if the left and right sides are different, air can be blown out into the septic tank in a well-balanced manner from the left and right horizontal pipes. In addition, since the hole diameter of the air outlet can be made larger, there is less clogging of the air outlet, so even if it is used for a backwash pipe etc. that is used after a certain period of time, the air outlet will not be clogged and the air can be reliably placed inside the septic tank. air can be blown out.
