It is possible to store and fix it. .

Description

[Detailed explanation of the idea]

0001

[Industrial application field]

This idea is based on a septic tank with an improved structure of the support that supports the contact material installed inside. Regarding.

0002

[Conventional technology]

The structure of a conventional septic tank will be explained based on FIGS. 3 and 4. Inside the septic tank 1, A contact material 2 is accommodated, and in order to accommodate and hold this contact material 2 in the proper position, a cut-off is required. The L-shaped mounting plates 3 and 4 are attached to the holder 7 on the side wall 5 of the septic tank 1. It is also fixed directly to the six partition walls by means of mounting such as screws. There is.

0003 Furthermore, in order to clean this contact material 2, a backwash pipe 8 is provided with a large number of air holes 8a. is installed, and this backwash pipe 8 is attached to the mounting plates 3 and 4 with brackets 9 and It is attached via a tool 9a.

0004

[Problem that the idea aims to solve]

In this way, in the configuration of the conventional septic tank 1, the contact material 2 housed inside is held. The mounting plates 3 and 4 for cleaning and the backwash pipe 8 for cleaning the contact material 2 are installed. , and the contact material 2 and backwashing due to corrosion of the screws. There is a risk that the pipe 8 may fall off, so make sure to securely connect the contact material 2 and backwash pipe 8 inside the septic tank 1. The challenge was to install it.

[0005] Furthermore, mounting holes for screwing are set in the side wall 5 and partition wall 6 of the septic tank 1. Therefore, there is a problem of water leakage, and in addition, the mounting plates 3 and 4 and the backwash pipe The problem is that the installation work in item 8 is performed in a narrow space, resulting in poor installation workability. This point has also been pointed out at the same time.

[0006] This invention was made in view of these circumstances, and the purpose of this invention is In a septic tank with a contact material and a backwash pipe installed inside, the roller is used as a contact material support and Easy and reliable installation of septic tank and backwash pipes, and also reliably prevents water leakage from the septic tank. Our goal is to provide a septic tank that is designed to

[0007]

[Means to solve the problem]

In order to achieve the above objective, the present invention supports the contact material by an internally installed support. In a septic tank that is housed and maintained in an appropriate position, The support is formed by bending a resin hollow pipe, and includes a holding part that holds the contact material. , the above-mentioned holding part should be placed in the correct position in the septic tank by touching the partition wall and bottom of the septic tank. It consists of legs that are positioned in the It is characterized by having many holes.

[0008]

[Effect]

As is clear from the above configuration, the legs of the support are attached to the partition wall and bottom of the septic tank. By abutting against a surface, the support can be easily positioned inside the septic tank, making it possible to easily position the support in the septic tank. Fixing means such as screws can be eliminated.

[0009] Furthermore, the support is made of a resin hollow pipe, which also has the function of cleaning the contact material. Therefore, the conventional backwash pipe can be abolished.

0010 In addition, it is necessary to make mounting holes for screws on the side walls and partition walls of the septic tank. Since there is no water leakage, conventional problems such as water leakage can be reliably prevented.

[0011]

【Example】

Below, one embodiment of the septic tank according to the present invention will be explained in detail based on Figures 1 and 2. Ru.

0012 Figure 1 is a partially cutaway perspective view showing the state in which the support is installed in the septic tank, and Figure 2 is a similar view of the septic tank. FIG. 3 is a sectional view showing a state in which the support tool is installed in the chemical tank.

[0013] In FIGS. 1 and 2, a support 3 that supports a contact material 20 accommodated in a septic tank 10 0 is formed by bending a hollow pipe made of synthetic resin, and this support 30 is a contact material 20. A holding part 31 that holds a 32, 33 (the one extending laterally is 32, and the one extending downward is 33) Furthermore, the holding part 31 of the support 30 has air holes 34 for backwashing at regular intervals. Many have been established.

[0014] The support device 30 according to the present invention is configured as described above, and is installed in the septic tank 10. When cutting, the leg portions 32 extending laterally of the support 30 come into contact with the surface of the partition wall 11. At the same time, the legs 33 extending downward contact the bottom surface 12 of the septic tank 10. , the support 30 can be positioned at an appropriate position in the septic tank 10, and the holding part 3 of the support 30 It is only necessary to place the contact material 20 on top of the contact material 20.

[0015] Therefore, unlike conventional methods, it is difficult to tighten screws in the narrow space inside the septic tank 10. Since the work etc. can be eliminated, work efficiency is significantly improved, and the partition wall 11 and side There is no need to provide screw holes on the wall, and the problem of water leakage is also eliminated.

[0016] Also, air is supplied to the backwash air hole 34 provided in the support 30 through the air supply pipe 35. By sending it in, the contact material 20 can be cleaned, the conventional backwash pipe can be abolished, and the work can be performed more easily, and can also be expected to reduce costs by reducing the number of parts. .

[0017]

[Effect of the idea]

As explained above, the septic tank according to the present invention has the following special effects: have (1) The support that supports the contact material is configured with a hollow pipe shape, and the legs provided on the support are The structure is such that the support is fixed by coming into contact with the partition wall and bottom. , compared to conventional screw fixation, allows for reliable fixation over a long period of time, making it easier to attach contact materials. This has the effect of improving stability. (2) It can be fixed simply by setting the support inside the septic tank, so it can be fixed simply by setting the support inside the septic tank. There is no need to provide screw holes on the walls or side walls, and the watertightness of the septic tank is improved. have fruit. (3) The contact material support, which also serves as a backwash pipe, can be fixed by simply setting it inside the septic tank. This has the effect of greatly improving work efficiency. (4) By using it as a backwash pipe and significantly reducing the number of installed parts, This has the effect that a significant cost reduction can be expected.
