The present invention relates to a partition wall device installed in a water treatment plant, in particular, a sewage treatment plant, and more particularly, to form an opening in the partition wall of the water treatment plant to minimize the influence of water pressure until the overflow through the partition wall, both sides of the partition wall When the head (pressure) of is approximately equal, the opening of the wall is sealed to induce normal water treatment, and in particular, the opening and closing of the opening is realized by using the head (pressure) without delivering a driving source, thereby simplifying the structure of the opening and closing means. The present invention relates to a water treatment plant partition wall device, which facilitates the construction and maintenance of the partition wall, thereby reducing the construction cost.

The partition walls used in water treatment plants, in particular in sewage treatment plants, are known.

For example, FIG. 1 shows an example of the partition wall 100 of a known sewage treatment plant.

That is, as shown in Figure 1, each reaction tank of the bioreactor (secondary treatment plant) 110, which is located between the primary sedimentation basin and the secondary sedimentation basin in the sewage treatment plant and cleans the sewage (waste, waste water) biologically Between the anoxic tank # 1 (120) and the subsequent anoxic tank # 2 (130) and the aerobic tank 140, the partition walls (100) are installed across the bio-ban coagulation 110 so that the treated water is purged while being stepped over. .

Meanwhile, in FIG. 1, the treated water that has passed through the bioreactor is sent to the secondary sedimentation basin through the adjacent settling tanks 150 step by step, and such a settling tank 150 may be provided with a partition wall although not shown in the drawing.

Next, FIG. 2 and FIG. 3 show the partition wall 100 of the water treatment plant, that is, the sewage treatment plant, schematically illustrated in FIG. 1.

That is, as shown in Figures 2 and 3, the partition wall 100 of the sewage treatment plant, a plurality of unit panels 102 are made of stainless steel across the concrete structure (110a) of the sewage treatment plant, for example, bioreactor 110 It is assembled using the assembly steel, such as the section steel 104, or chanel (106).

At this time, the downstream side (rear) of the trunk wall 100 is provided with fixing bars 108a and 108b fixed to the bottom of the structure and the structure side walls, respectively, to reinforce the strength of the trunk wall. 108b is a side wall fixing stand)

However, since the wall 100 of the conventional water treatment plant has a substantial depth and width of the structure of the sewage treatment plant, when water flows to one side of the trunk wall and flows to the downstream side of the partition wall, the water pressure applied to the partition wall is increased. It is considerable.

Thus, as shown in Figure 3a to Figure 3c, the conventional water treatment plant, that is, the sewage wall 100 is installed in the sewage treatment plant bioreactor 110 is fixed to the back and fixed to the structure bottom and the side wall downstream downstream 108a (108b) are provided, but in spite of the fixtures such as this, there is a problem that the barrier wall is broken or its life is very short as a considerable hydraulic pressure is applied to the barrier wall 100.

That is, even though the conventional water treatment plant, in particular, the sewage treatment plant partition walls 100 are firmly fixed to the bottom and sidewall of the concrete structure 110a through the fixing bases 108a and 108b, since the structure depth of the sewage treatment plant is substantial, If the water fills upstream of the partition wall, the water pressure applied to the partition wall cannot be tolerated for a long time.

Accordingly, Applicants of the present invention to minimize the influence of the water pressure up to the point of the overflow through the partition wall by forming an opening in the water treatment plant partition wall, and if necessary to open and close the opening of the partition wall through various types of opening and closing means In particular, the present invention has been proposed to extend the life span by facilitating the maintenance of the wall and construction after construction.

The present invention has been proposed in order to solve the conventional problems as described above, the object of the aspect is to form an opening in the wall of the water treatment plant to minimize the effect of the water pressure until the overflow through the partition wall ultimately extends the life of the partition wall When the head wall opening is almost equal to the head (pressure) of both sides of the partition wall, the partition wall opening is closed to induce normal water treatment, and especially the head (pressure) without a separate driving source is delivered. By providing a non-driven opening and closing means using a), it is to provide a water treatment plant partition wall device that implements a simplified structure of the opening and closing means.

According to the water treatment plant partition wall device of the present invention, by forming an opening in the water treatment plant partition wall to minimize the influence of water pressure until the overflow through the partition wall, thereby facilitating maintenance of the wall after construction or construction It provides an excellent effect of extending its life.

In addition, the present invention, if the head (pressure) of both sides of the partition wall is almost equal, the closing of the wall opening to induce normal water treatment, in particular, the non-driven opening and closing using the head (pressure) without a separate drive source transmission By providing the means, while simplifying the structure of the opening and closing means, it is possible to reduce the construction cost and to provide other excellent effects to facilitate the operation management.

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

First, Figure 4 shows the water treatment plant partition wall device of the first embodiment according to the present invention.

That is, as shown in Figure 4, the water treatment plant partition wall apparatus of the first embodiment of the present invention, the water treatment plant, for example, the partition wall 100 provided across the structure of the sewage treatment plant (bioreactor 110 of) And a rectangular wall opening 300 (square) formed in the panel 102 constituting the trunk wall.

Accordingly, the present invention partition wall 100 of FIG. 4 minimizes the influence of the water pressure applied to the partition wall because the initially introduced water (W in FIG. 2) flows downstream of the trunk wall through the opening 300 formed in the partition wall. .

Then, as shown in FIG. 9C, which will be described in detail below, when both sides of the wall are filled with water, and both pressures (water heads) applied to the walls are equal, water flows through the walls, and the heads on both sides of the walls are almost equal. Since the water pressure applied to the trunk wall on both sides (upstream and downstream) of the trunk wall is almost equal, the trunk wall receives the same hydraulic pressure on both sides, so that problems such as deflection of the trunk wall to one side do not occur.

That is, in the conventional partition wall 100, as shown in Figs. 2 and 3, even if the fixing base (108a, 108b) is fixed to the bottom of the structure and the structure side wall, respectively, the depth of the structure is large and applied to the partition wall upstream of the partition wall If the water pressure is considerable and there is no opening 300 provided in the trunk wall of the partition wall device of the first embodiment of the present invention, the hydraulic pressure is significantly affected.

On the other hand, the partition wall opening 300 of the present invention is preferably closed because the water pressure applied to both sides of the partition wall is almost equal to the head of the trunk wall, because it gives the same force to support the partition wall, the opening and closing structure to implement this Will be described below.

Next, Fig. 5 and Figs. 6 to 12 show the partition wall apparatus of the second and third embodiments according to the present invention.

That is, the trunk wall device of the second and third embodiments of the present invention of FIGS. 5 and 6 to 12 relates to the trunk wall opening opening and closing means for intentionally closing the opening 300 formed in the trunk wall described above.

For example, in the trunk opening 300, when the water is filled on both sides of the trunk wall as shown in FIG. 9C, the water pressure (water pressure) becomes almost equal, and the water continuously flowing flows over the barrier wall to the downstream side of the barrier wall. While passing through each reaction tank 120, 130, 140 of the bioreactor 110 of FIG. 1 step by step, water purification is performed.

Therefore, when water overflows to both sides of the partition wall, it is preferable to close the partition wall opening 300. If such an opening is left open, untreated water during the actual water purification treatment is the partition wall opening. This is because it flows through to the next stage.

Thus, the trunk wall device according to the second embodiment of the present invention shown in FIG. 5 shows a driving trunk wall opening opening / closing means 200 for opening and closing the trunk wall opening 300 using a driving source.

That is, as shown in Figure 5, the partition wall device 1 of the second embodiment according to the present invention, the liver wall 100 is installed across the water treatment plant structure and includes one or more openings 300, and It is configured to include a drive-type opening wall opening and closing means 200 is provided in association with the opening wall to open and close the opening of the partition wall.

For example, the drive-type opening wall opening and closing means 200 of the present invention shown in Figure 5, the opening opening and closing plate 220 provided slidably between the channel 210 provided on the opening 300 side of the partition wall 100. And a driving source connected to the lifting bar 230 connected to the opening and closing plate and installed vertically, wherein the driving source includes, for example, a rod coupling block 250 to which the lifting bar is fastened and disposed in the water treatment plant structure. It may be an associated manipulation handle 240.

Alternatively, the driving source may be a hydraulic, pneumatic cylinder or other electrically driven actuator connected to the lifting rod (not shown).

Accordingly, when the operation handle 240 is operated, the opening and closing plate 220 between the openings 300 and the side panel 210 of the panel 102 connected to the lifting bar 230 is elevated according to the operation direction thereof. While opening and closing the liver wall opening.

That is, the drive-type opening wall opening and closing means 200 of the embodiment of the present invention of Figure 5, it can be seen a kind of winch 200.

Next, Figs. 6 to 12 show the water treatment plant partition wall apparatus 1 of the third embodiment according to the present invention. The water treatment plant partition wall apparatus 1 according to the third embodiment of the present invention is a water treatment plant (sewage). The liver wall 100 is installed across the structure 110a of the treatment plant) and includes one or more liver wall openings 300, and the opening is connected to one side of the opening of the liver wall without additional manipulation by hydraulic pressure on both sides of the liver wall. It may be configured to include a non-driven open wall opening and closing means provided to open and close.

That is, the non-driven opening wall opening and closing means of the present invention, as described in detail in the following Figures 6 to 12, a separate driving force different from the drive-type opening wall opening and closing means 200, such as the winch of Figure 5 Alternatively, the operating force is not transmitted, but it is possible to automatically open and close the trunk wall opening 300 according to the head (pressure) by using the water pressure (water head) of the water filled on both sides (upstream and downstream) of the trunk wall. have.

Therefore, the non-driven interlock opening and closing means of the present invention described in detail with reference to Figs. 6 to 12 does not transmit external driving force or operating force differently from the driven interlock opening and closing means of Fig. 5, and thus the installation cost. Will reduce operational complexity. In particular, the structure is simple.

In addition, the non-driven trunk opening opening means such that the barrier opening is not opened or closed if necessary due to a misoperation or a missing operation of the driving barrier opening opening means described above. It will suppress the occurrence of overload.

At this time, the partition wall opening 300 of the present invention, as shown in Figure 4, is provided on both sides of the lower portion of the partition wall, and thus the drive and non-driven partition wall opening opening and closing means of the second and third embodiments of the present invention are also partition walls. It is a matter of course that the same number is installed depending on the number of openings.

Next, the non-driven trunk wall opening opening and closing means of the present invention, specifically, the pivotable trunk wall opening opening and closing means 10 or 10 to FIG. According to the water pressure shown in 12 may be divided into a sliding-type opening wall opening and closing means 30 for opening and closing the opening wall while sliding vertically along the partition wall.

Of course, it is also possible to install such a rotational or sliding type interlocking opening and closing means 10, 30 in a single partition wall of course.

For example, in the non-driving trunk wall opening opening and closing means of the third embodiment of the present invention, the present invention pivotal trunk opening and closing means 10 of Figs. 6 to 9 is the sliding trunk wall opening of the present invention of Figs. Compared to the opening and closing means 30, the structure provides a simple advantage, and on the contrary, the sliding type opening wall opening and closing means 30 is complicated, but since the opening and closing of the opening wall 300 in a sliding form, the opening blocking property is more reliable. can do.

Therefore, the opening and closing means may be selectively used in consideration of the size of the partition wall installation.

Hereinafter, it looks at in detail with respect to the rotation type and the sliding inter-wall opening and closing means (10, 30).

First, as shown in FIGS. 6 to 9, the pivot type opening / closing opening and closing means 10 of the present invention includes a pivot member 12 installed in the panel 102 on which the trunk wall opening 300 is formed. And, it may be composed of the interlocking opening opening and closing member that is fastened to the rotating member 12 while being in close contact with the interlocking opening according to the hydraulic pressure.

At this time, the rotation member 12 may be provided as a hinge provided between the support member 14 and the opening and closing member, such as' '' shape installed in the panel 102 on the side of the gap opening 300.

At the same time, the opening and closing member is provided as a thin plate member 16, as shown in Figs. 6 to 7, or as the panel 102 constituting the partition wall 100, as shown in Figs. It may be provided as a panel member 18 of the).

However, in the case of the plate member 16, as shown in Figs. 6 and 7, the hinge member 12 of the hinge is connected to the support member 14 and the plate member back that is a steel, and in the case of a panel member Similarly, there is only a difference in which the hinge member 12 of the hinge is connected between the shaped steel 20 and the support member 14 fixed to the upper end of the panel member 18.

At this time, when the plate member 16 or the panel member 18 descends by hydraulic pressure on the bottom side of the structure, a section steel 14 supporting the lower end may be installed.

Of course, such a shaped steel may be fixed across the panel opening portion through which the trunk opening 300 is formed.

Therefore, referring to the operation of the pivotal opening / closing opening and closing means 10 as described above, referring to the pivotal opening and closing means 10 including the opening and closing member of the panel member 18 of FIG. As shown in the figure, when water (W) flows into the upstream side of the wall of the concrete structure 100a of the bioreaction 110 of the water treatment plant, for example, a sewage treatment plant, it flows to the downstream side of the wall through the interwall opening 300.

Then, as shown in FIG. 9B, water is filled with the same head on both sides (upstream and downstream) of the trunk wall through the trunk wall opening 300, and as shown in FIG. 9C, when the trunk wall 100 flows over, the heads on both sides of the partition wall become It is almost the same, so that the water flows through the barrier wall opening 300 directly through the barrier at the water surface, rather than passing through, the opening and closing member 18 connected to the panel by the hinge of the pivot member 12 is automatically lowered to open the barrier wall opening. Close 300.

Therefore, water no longer flows through the opening of the partition wall, and only the surface-side treated water treated through the biological reaction flows through the partition wall to the next space (reactor).

Next, as shown in FIGS. 10 to 12, the sliding-type opening wall opening and closing means 30 according to another embodiment of the present invention includes guide members 32 installed on both sides of one side of the opening wall, that is, 'c'. Sliding opening and closing member 36 and the sliding opening and closing member 36 and the other end of the spring 34, which is provided to be slidably provided between the male steel is connected to the bracket (34a) is fixed to the upper portion of the guide member, It may be composed of a hydraulic pressure applying plate 38 having a predetermined area mounted horizontally.

10 and 11, the hydraulic pressure applying plate 38 may be detachably assembled to the opening / closing member 36 formed of a plate or panel member, for example, an opening / closing member of a plate or panel member. In the case where the groove 36a is formed in the longitudinal direction at the center side of the 36, and the protrusion 38a of the hydraulic pressure application plate 38 is inserted by force fitting, the hydraulic pressure application plate can be assembled in a different size. do.

Therefore, as shown in FIG. 10, when the hydraulic pressure applying plate 38 having a large area is assembled, the sliding timing using the hydraulic pressure applying plate may be adjusted because the influence of the hydraulic pressure applied to the application plate becomes larger.

12A and 12B, according to the sliding trunk wall opening and closing means 30 of the present invention, since the pressure applied to the hydraulic pressure applying plate 38 is small at the initial stage when water is introduced, That is, since the elastic force of the tension spring 34 is greater, the sliding opening and closing member 36 does not descend in the vertical direction along the guide member 32, so that water flows downstream of the trunk wall through the trunk wall opening 300.

However, as shown in Fig. 12B, at the time when water is filled on both sides of the trunk wall and the water flows over the trunk wall, the head on the downstream side of the trunk wall that pressurizes the hydraulic pressure applying plate 38 becomes high, and thus the hydraulic pressure applied to the hydraulic plate (Fig. F) of 12b is greater than the elastic force of the tension spring 34, and thus the opening and closing member 36 descends along the guide member 32, thereby closing the inter-wall opening 300 while reaching the bottom of the structure.

Therefore, in the sliding trunk | drum opening opening / closing means 30 of this invention, when the water | water head which fills the elastic force of the spring 34 to the downstream side of a trunk | bulb, and water overflows the trunk | drum is formed, it is applied to a hydraulic pressure application board. It is necessary to adjust to enable the sliding opening and closing member 36 to descend by the losing pressure.

Of course, it is also possible to make the sliding opening / closing member 36 descend when the water is filled at about 90% on the downstream side of the wall, not necessarily at the time of overflowing, so as to completely close the wall opening when the water flows.

Since the spring's elastic force has a fixed depth and width, and the height of the interstitial wall 100 through which the water flows is constant, the spring's elastic force may be selectively adjusted according to the amount of water to be sufficiently calculated and filled in the downstream side of the interstitial wall. .

While the invention has been shown and described in connection with specific embodiments so far, it will be appreciated that the invention can be varied and modified without departing from the spirit or scope of the invention as set forth in the following claims.
