Detailed description of the invention

(Industrial use)

The present invention relates to a waste concrete wastewater sedimentation tank, and more particularly, to a waste concrete wastewater sedimentation tank capable of efficiently treating waste concrete from a construction site and flowing it to a sewage outlet.

(Prior art)

Conventional waste concrete wastewater sedimentation tank is generally made of a rectangular parallelepiped, the upper part of which is opened, a drainage hole is formed on the outlet side, and a purification tank part and an inlet side sedimentation tank into which waste concrete is introduced by installing a partition wall in the center of the purification tank part; It consists of an outlet sedimentation tank where the waste water is purified and flows to the sewer through the drain hole.If the waste concrete is put together with the groundwater in the inlet sedimentation tank, the gravel and sand having a high specific gravity will precipitate and the small specific gravity particles will enter the sedimentation tank. When it settled and the water reached a certain level, it was discharged to the sewer through the drain hole.

(Problems with Prior Art)

However, in the conventional waste concrete sedimentation tank, firstly, gravel and sand having a relatively high specific gravity are precipitated in the inlet sedimentation tank, and the fine particles are partially precipitated in the outlet sedimentation tank, but most of the fine particles are discharged together with the wastewater. Since the wastewater is discharged to the sewer, there is a problem in that the wastewater is discharged to the sewer without being completely purified and contaminates the stream.

Secondly, since the waste concrete is poured directly into the inlet sedimentation tank, there is a problem of contaminating the surrounding by splashing the wastewater accumulated therein.

Third, when the waste concrete is poured into the inlet sedimentation tank, gravel, wood chips, styropol pieces, etc., enters the sedimentation tank, so there is a problem in that the sedimentation tank should be frequently cleaned.

(Purpose of invention)

Therefore, the present invention was devised to solve the problems described above, first, to efficiently purify the waste concrete to be sent to the sewage outlet, and second, when the waste concrete is poured into the waste water to the outside The third object is to provide a waste concrete wastewater sedimentation tank that can be prevented, and to facilitate the cleaning of each sedimentation tank.

(Means to solve problems)

The waste concrete wastewater sedimentation tank according to the present invention for achieving the above object is made of a generally rectangular parallelepiped, the upper part of which is opened and a drainage hole is formed on the outlet side, and a partition is installed in the middle of the inner side of the purification tank part. A sedimentation tank consisting of an inlet sedimentation tank into which concrete is introduced and an outlet sedimentation tank in which waste water is purified and flows to a sewer through a drain hole, wherein partition walls are gradually moved from the inlet side to the outlet side at predetermined intervals inside the purification vessel. Its height is gradually lowered and consists of the inlet sedimentation tank, the intermediate sedimentation tank, and the outlet sedimentation tank, and a fixed base is installed on the inner side wall of the sedimentation tank opposite to the inlet side sedimentation tank so that the upper surface of the net is covered. The outlet side sedimentation tank is configured to be filled with activated carbon so that the waste concrete can be efficiently Purification by features configured to send the sewage flows into the outlet.

(Configuration)

Hereinafter, with reference to the accompanying drawings, the present invention will be described in detail.

1 is a perspective view showing the waste concrete wastewater sedimentation tank according to the present invention, Figure 2 is a side cross-sectional view showing the waste concrete wastewater sedimentation tank according to the present invention.

As shown in these figures, the waste concrete wastewater sedimentation tank according to the present invention is made of a rectangular parallelepiped as a whole, the upper part of which is opened and a drainage hole is formed on the outlet side, and a partition wall is installed in the center of the purification part. A settling tank composed of an inlet settling tank into which waste concrete flows in and an outlet settling tank through which waste water is purified and flows to a sewer through a drain hole, the partition walls 23a and 23b at predetermined intervals in the purification tank section 10. ), The height is gradually lowered from the inlet side toward the outlet side, and consists of the inlet settling tank 20a, the intermediate settling tank 20b, and the outlet settling tank 20c, and the settling tanks 20a, 20b, and 20c. Among them, a fixed pedestal 22 is installed on an inner side wall of the inlet sedimentation tank 20a to cover the mesh 2l on the upper side thereof, and the activated carbon 30 is disposed on the outlet side sedimentation tank 20c. It is configured to be filled, thereby purifying the waste concrete efficiently is characterized on the technical configuration adapted to send the flow to the sewer outlet.

Here, the heights of the partitions 23a and 23b are gradually lowered toward the outlet side sedimentation tank 20c from the inlet side sedimentation tank 20a toward the outlet side sedimentation tank 20c at predetermined intervals. Thus, the wastewater introduced from the inlet side sedimentation tank 20a can flow smoothly toward one side sedimentation tank 20a, 20b, and 20c.

In addition, the inlet side settling tank 20a among the plurality of settling tanks 20a, 20b, and 20c is covered with the net body 21 on the upper part thereof, so that when the waste concrete is poured into the net body 21 once it reaches the net body 21. Falling out of the sedimentation tank prevents the waste water from splashing out, and makes it easier to clean the sedimentation tanks 20a, 20b, and 20c by catching relatively large objects such as dirt and garbage on the net body 21, and exit side sedimentation tank 20c. In order to further purify the waste water by filling the activated carbon 30 in the adsorbed fine particles.

In addition, by installing a fixed support 22 on the inner wall of the inlet side sedimentation tank 20a so as to place the net body 21.

That is, when the waste concrete is poured into the inlet sedimentation tank 20a having the mesh 21 formed thereon together with the washing water, large objects such as gravel and rubbish are filtered out of the mesh 21, and small particles of sand, etc. ) Is settled at the bottom of the inlet sedimentation tank (20a), and when the inlet sedimentation tank (20a) is full of washings, overflows to the first bulkhead (23a) to accumulate in the middle sedimentation tank (20b), and at this time relatively small grains When precipitated in the settling tank (20b), when the washing water is filled in the intermediate settling tank (20b) flows over the second partition 23b flows into the outlet side settling tank (20C) containing the activated carbon 30, fine particles are activated carbon (30) The water adsorbed and finally purified is then used to discharge to the sewer through the drain hole l1.

In this case, as shown in FIG. 1, the purifying cylinder part 10 is made of a rectangular parallelepiped as a whole, and made of metal or synthetic resin material and installed at each construction site so that the construction can be repeatedly used when moving to another construction site. The upper surface of the purifying cylinder part 10 is embedded in a cart to transport the waste concrete to be poured into the purifying container part 10 so as to be flush with the ground, and to the outlet side sedimentation tank 20c of the purifying container part 10. The drain hole 11 is formed to connect the drain pipe 40 extending to the sewer to discharge the purified water to the sewer.

On the other hand, the position of the drain hole 11 is formed in the outlet side sedimentation tank (20c), as shown in Figure 2, the second partition wall (23a, 23b) is the lowest partition wall (23a, 23b) to prevent the back flow 23b) to be formed at a lower position so that the washing water flows smoothly toward the sewer, and the mesh pipe 21 is installed at the inlet of the drain hole 11 so as to filter the waste, so that the drain pipe 40 is blocked. Prevent it.

The settling tanks 20a, 20b, and 20c are divided into an inlet settling tank 20a, an intermediate settling tank 20b, and an outlet side settling tank 20c, as shown in FIG. 1, and each settling tank 20a, 20b, 20c. The first partition 23a and the second partition 23b are installed and separated therebetween.

In this case, as shown in FIG. 2, the heights of the partitions 23a and 23b are lower than those of the first partition 23a so that the water overflows the partitions 23a and 23b so that the water flows through the drain holes 23. 11) has an effect flowing smoothly to the sewer.

In this case, the partitions 23a and 23b are integrally welded to the inner surface of the purification vessel 10. In particular, the upper portion of the inlet side sedimentation tank 20a covers the net body 21 so that when the waste concrete is poured into the inlet side sedimentation tank 20a, the waste concrete reaches the net body 21 and falls in the settling tank so that the wastewater is discharged. In addition to preventing splashing, sewage and garbage are caught on the mesh 21 so that when cleaning the trash filtered on the mesh 21, the mesh 21 itself can be lifted to easily contain the waste in the trash. Make it easy to clean the 20a, 20b, 20c.

At this time, the net body 21 can be detached so that the waste to be filtered thereon can be easily cleaned, the material of the net body 21 is preferably made of metal that requires structural strength because the gravel is poured, The size of the net body 21 is preferably matched with the size of the inlet side settling tank 20a.

Meanwhile, as shown in FIG. 1, the fixing base 22 fixing the net body 21 welds an angle to an inner side wall of the purifying tank part 10 so as to weld the angle to the upper end of the angle 21. The opposite edge is raised, and the angle welded height is positioned higher than the first partition 23a so that when the network 21 is installed, the water is formed in the space formed above the first partition 23a and under the network 21. It smoothly flows to the intermediate settling tank 20b.

In addition, the outlet side sedimentation tank 20c is filled with activated carbon 30 so as to adsorb the fine particles of cement powder, so as to further purify the waste water.
