Abstract

PURPOSE:To permit increasing of the length of one side in the upper half part of a settling tank and to assure the capacity of the settling tank sufficiently, by projecting the upper parts between both side parts in the axial direction of a housing for a purifying tank contg. the settling tank to the outside in conformity with the shoulder parts on both sides of the settling tank to be contained therein. CONSTITUTION:A settling tank 3 is contained in a housing 4 for a purifying tank. The upper half part 1 of the tank 3 is a square shape which is of the same shape over the entire length in a longitudinal direction. The lower half part 2 thereof is of an inverted conical shape of which the diameter decreases downward, and the bottom part thereof is placed on the bottom surface of the housing 4. The upper pat of the housing 4 projects and curves upward to form projecting parts 6 which are so formed that the shoulder parts 5 on both sides of the part 1 of the tank 3 are contained in the parts 6. The dimensional limitation of the housing 4 is relieved by as much as the projecting parts 6, and by this relieving, the length of one side in the part 1 of the settling tank is increased and the capacity of the settling tank is increased.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a septic tank with a built-in sinker. The sedimentation tank (3), which has an inverted conical shape, is inserted into the horizontal cylindrical housing (41, housing J) + 41 from the upper part located on both sides in the axial direction of the housing (4). This relates to a purification cypress with a built-in sedimentation tank characterized by the shoulders (6) on both sides of the upper half i1111 of the sedimentation tank (31) protruding and collapsed.In general, in the cylindrical combined sedimentation purification cypress of FRPIII,
There is no example of a built-in sedimentation tank built into the tank, except for small-sized cypress trees (treated water capacity: 15 trt/day).

Almost all of the conventional septic tank enclosures are separated into separate tanks as shown in Figure 1.The disadvantages of this type of septic tank construction are: ■ How is the construction? .

1. Since it is a separate tank, a bi-connection is required Δ 2. In most cases, the height is not the same as the main body, so it is necessary to add a step to the foundation slab.

3. Because the bottom is hopper-shaped, it is difficult to hold it upright.

■ The quality of construction affects performance.

If the construction is sloppy, it may cause a reverse slope of the pipe,
It may not be level or it may not come out properly, which will affect the performance.

■ A stand is required at the bottom, which is costly.

The bottom of the sink tIl# itself is very narrow, so
Without a stand, it is impossible to stand on its own.

However, if you choose this type and incorporate the sink m-+a etc. in the housing (4f) as shown in Figure 2,
This is because dimensional limitations occur and the specified capacity cannot be secured. Specifically, as shown in Figure 2, the river angle k(θ

) for K [mFio, 2L, etc., according to the structure & semi-regulations,
J2r2500M housing (maximum approx. 3.8 at 41')
Only - capacity can be secured.

The present invention has been made in consideration of the above points, and its purpose is to provide an Ik type purification right in a sedimentation tank that can secure a specified capacity even if the sedimentation tank is built-in. .

It is composed of the lower half i +21 and the upper half (1),
The upper half (1) Fi has the same diameter over the entire length in the vertical direction, and the lower half (21 Fi) is formed in an inverted conical shape (hopper shape) with the diameter becoming smaller as it goes downwards.Housing (4・The parts located on both stools 1 with respect to the axial direction of the housing (4) are bent upward and protrude ill>+6'

7), and a rectangular frame for supporting the machine hole is formed from the periphery of the opening (7).

Now, if the settling tank ts+ satisfies the R condition of the structural standard as shown in Figure 5, the specified capacity v#-i is expressed by the following equation: V=L

It would be better to increase the stagnation to secure it, but the housing of the septic tank (4), which is about 02,500 pieces, is usually used.
There is a limit within the condition. Therefore, by protruding the chest II>16 of the sedimentation tank (3) as in the present invention, it is possible to overcome the dimensional limitations of the rehabilitation tank (3) and increase the size of the sedimentation tank (3). It becomes possible.

As described above, the present invention has a sedimentation tank built into a horizontal cylindrical housing, which has an inverted conical shape in which the upper half has the same diameter over the entire length in the vertical direction and the lower half has a smaller diameter as it goes downward.

Since the JMifl> on both sides of the upper half of the sedimentation tank protruded from the upper part of the housing located on both sides in the axial direction of the housing, the dimensional limit of the housing was
The length of the septic tank that protrudes from the housing has been relaxed, and this relaxation has made it possible to increase the length of one side of the septic tank where the water surface is located, ensuring the specified capacity.Moreover, it has a built-in sedimentation tank, making it easier to construct the septic tank. The advantage is that it can be improved.
