Description

[Detailed Description of the Invention] This invention relates to an improvement in a connecting device between a tank and connecting pipes such as an inlet pipe, an advection pipe, and an outflow pipe.

Conventionally, for example, when connecting two separate aeration-type septic tanks, for example, one tank was installed in the appropriate position, a connecting pipe was connected to the connection socket of one tank, and then the other tank was connected to the position of the connecting pipe. Accordingly, the connecting tube was moved horizontally and inserted into the other connecting socket to connect both tanks.

However, horizontally moving the tank itself requires a great deal of effort, and the difficulty increases as the tank becomes larger. Not only is the work efficiency extremely low, but the work itself involves many dangers. It had the disadvantage of being accompanied by

Furthermore, if the centers of the connection sockets of the connecting parts of both tanks do not match, the work must be stopped, the tank positions must be corrected so that the centers match, and then the connections are made, making the work process complicated. It had the disadvantage of becoming.

This invention eliminates the above drawbacks and prevents the tank from moving by filling the filling part of the fixture that supports the connecting pipe inserted into the opening hole of the tank and fixing the connecting pipe to the tank. To provide a tank pipe connecting device which can easily and reliably connect a connecting pipe to a tank, can connect reliably even if the arrangement positions of each tank are slightly shifted, and can improve work efficiency.

An embodiment of this invention will be described below with reference to the drawings. Fig. 1 is a cross-sectional view of the pipe connecting device according to the invention, Fig. 2 is a perspective view of the same, Fig. 3 is another embodiment of the mounting part of the above device, and Figs. 4 and 5 are the same. A schematic cross-sectional view when the device is applied to a tank is shown.

This invention consists of a connecting pipe 3 inserted into an opening 2 in the side wall of a tank 1, and a fitting 4 that supports this connecting pipe 3.
and a filler 5 filled in this fixture 4.

The connecting pipe 3 is, for example, an advection pipe that connects two tanks, and as shown in FIG. The other end of the tub 1 that is inserted and protrudes outward is supported by the fixture 4 mentioned above.

As shown in Figs. 1 and 2, the mounting fixture 4 has an opening 6 through which the protruding end of the connecting pipe 3 is inserted and supported.
and a filling portion 7 for filling the filling material 5. The filling portion 7 is substantially pocket-shaped.
and is fixed to the outer peripheral wall of the tank 1.

The filling material 5 is made of, for example, concrete or mortar, and is filled into the filling part 7 of the fixture 4 to firmly fix the connecting pipe 3 to the tank 1 and prevent water leakage from the connecting part between the two. completely prevented.

In this invention, when connecting two tanks 1, first attach the above-mentioned fittings 4 to both tanks 1, and then extend the connecting pipe 3 from inside one tank 1 toward the other tank and insert it into the other tank 1. do. Then, the filling portion 7 of the fitting 4 is filled with the filling material 5, and the connecting pipe is fixed.

Therefore, there is no need to move the tanks and connect them as in the past, and the connection work is not difficult or dangerous at all. In addition, since the opening hole 2 of the tank 1 has a larger diameter than the connecting pipe 3, the connecting pipe 3 can be connected to the tank 1 while allowing some inclination in the vertical and horizontal directions. Reliable connection is possible even if the center of the tank is slightly off-center.

The connecting pipe may be inserted into one of the tanks in advance, or may be inserted into the other tank from the outside at a slight angle.

FIG. 3 shows another embodiment in which the fixture 4 is attached to the inner circumferential wall of the tank 1, and has exactly the same effect as when it is attached to the outer circumferential wall of the tank 1 as described above. .

FIG. 4 shows another embodiment, in which two tanks are connected by the pipe connecting device according to this invention. In this embodiment, the fixture 4 is fixed to the outer peripheral wall of the tank 1. If the connecting pipe 3 is longer than the inner dimension R of the tank 1, it cannot be inserted into the tank, so it is connected with a socket 10 to connect both tanks. In this way, the connecting pipe 3 can also be inserted from the outside of the tank 1.

In addition, if the fixture 4 is prepared to correspond to the shape of the tank 1, it does not matter what shape the tank 1 is to be connected, and the tank 1 is not limited to an FRP tank, but can also be made of a material with a thin film structure. Bye.

Further, the above-mentioned fixture 4, like the above-mentioned embodiment,
Since it can be easily fixed to the tank 1, for example, by screwing means, it can be assembled on site. Furthermore, since the fixture 4 can be attached to either the inner or outer circumferential walls of the tank 1, there is no difficulty in the installation work depending on the installation location of the tank. Furthermore, the pipe connecting device of this invention is useful as a connecting device for inlet pipes, outlet pipes, air pipes, etc. other than the connecting pipes for two tanks.

As described above, according to the pipe connecting device of this invention, connecting pipes can be easily connected between tanks without causing water leakage, regardless of the shape of the applicable tanks.
In addition, excellent practical effects such as improved work efficiency and no danger can be obtained.
