Description

Apparatus for weed outing scum of water treatment system

The present invention relates to a water treatment system for purifying raw water taken from rivers or lakes for drinking, and more particularly, to facilitate the precipitation of various foreign matters contained in raw water. The present invention relates to a scum removal device of a water treatment system, which is capable of easily removing scum that floats on the water surface in a mixed agglomeration process in which chemicals are injected into raw water to form flocs of foreign substances.

As you know, water is the most important resource for the survival of all living things, including humans. However, with the increase of population and urban concentration due to industrialization, various types of living water, industrial water, and agricultural water were required. Accordingly, water from rivers and lakes is collected and supplied to necessary areas through waterworks. .

In this way, the raw water taken from the river and the like contain not only various foreign matters, but also various pollutants due to environmental pollution, which are not suitable for use as drinking water. As a result, the raw water collected is purified to be appropriately drinkable through a predetermined water purification process and then supplied to the required area.

That is, the raw water collected by the vacuum pump through the intake tower is stored in the landing well, and chemicals are mixed in the mixed agglomeration station and mixed by agglomeration with a flash mixer to form flocs of foreign substances. It is then removed, and the water drained from it is filtered and disinfected and then watered to the home through the water pipe.

However, a large amount of scum is floated on the surface of the treated water during the water purification process, and this scum is not only visually bad but also adversely affects the water quality, so it must be removed from the treated water together with the settled sludge. Must be supplied.

Scum removal technology for this purpose is provided in various forms, for example, can be found in the Republic of Korea Utility Model Registration No. 0272682 and No. 0223223.

Utility Model Registration No. 0272682 describes a scum inlet of a cylindrical scum remover pivotally supported on a sedimentation basin, which is positioned on the water surface by a weight to remove flowing scum, and is connected to the scum eliminator on the other side of the weight by a wire. When the siphon type is filled with water and the siphon type is further lowered, the scum inlet is rotated so that the scum inlet is located at the upper surface of the water, and then the collected scum is discharged to the outside.

However, since the scum eliminator is collected by simply blocking the scum movement in the scum's movement path which is moved along the flow of the treated water, the scum elimination efficiency is not good. That is, when the scum moves along the treated water and is blocked by the scum eliminator, the scum collects near the scum inlet of the eliminator, but the scum does not flow into the eliminator because there is no flow of water in the eliminator.

Utility Model Registration No.0252231 is provided with a rotary scum remover having a blade radially on one side of the sedimentation basin and rotated so that the blade pumps the scum on the water together with the scum discharge channel.

However, these techniques are difficult to reliably remove scum, and there is a problem that a large amount of water is discharged with the scum. In addition, since the scum eliminator must be driven continuously, a lot of power is required.

The present invention was devised to solve the above-mentioned problems, and provides a scum removing device of a water treatment system capable of easily collecting and removing scum existing on the water surface and minimizing power consumed by the scum. Has its purpose.

Another object of the present invention is to provide a scum removing apparatus of a water treatment system that can minimize the amount of outflow of treated water that is unnecessarily discarded during scum removal.

In order to achieve the above objects, the scum removing device of the water treatment system according to the present invention has a scum inlet and a scum outlet at its circumference and at one end thereof, and both ends thereof face each other so that the scum inlet can be located at the water surface or the upper surface of the water. A scum collector tube pivotally supported on two walls to be inverted in a predetermined angle range and having a predetermined slope such that the scum discharge port has a lower level than the other end; A scum transfer means installed to circulate a predetermined trajectory in the agglomeration basin and forcibly transferring the scum existing on the water surface to push the scum into the scum collection pipe; And driving means for circularly driving the scum transfer means.

According to one preferred feature of this invention scum removing device, the scum conveying means is at least two driving wheels disposed at intervals in front of the scum inlet of the scum collection pipe and rotatably supported on the side wall of the coagulation paper; It is composed of a loop-shaped circulation member coupled to the driving wheel rotates and a plurality of blades are fixed at intervals so as to protrude to the outside of the circulation member to pull the scum into the scum collection pipe.

According to another preferred feature of the present invention scum removing device, the driving means is provided in the coagulation paper and consists of an agglomerator which is connected to any one of the rotating shafts of the scum transfer means by the drive chain.

Accordingly, the present invention can easily collect and remove scum present on the surface of the treated water, prevent unnecessary flow of the treated water, and minimize the power required for scum removal by using the existing agglomerator power. As a result, the present invention can greatly improve the reliability and efficiency of the water treatment system.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

1 to 3, the scum removing apparatus of the water treatment system according to the present invention is located on the surface of the treated water to collect scum (S) and the scum collection pipe (10) to the scum collection tube (10) It consists of a scum conveying means 20 for conveying the scum S and a driving means 30 for circularly driving the scum conveying means 20.

On the other hand, the scum (S) is most often generated in the process of mixing agglomeration to form flocs of fine suspended matter or organic matter in the water, the scum removal device of the present invention is preferably a mixed agglomeration paper (B: "" flocculation ") (Abbreviated as "G").

As shown in FIGS. 4 and 5, the scum collection pipe 10 has an axial long scum inlet 11 axially on the circumferential surface so that the scum S on the water surface can be introduced therein. At one end thereof, a scum discharge port 12 for discharging the scum S introduced therein to the outside of the coagulation paper B is provided.

The scum collection tube 10 is supported on two walls (W) opposite ends of the flocculation paper (B) so that a portion of the body is submerged in the water, the scum collection tube 10 is formed with a scum discharge port 12 It has an appropriate inclination α such that the end side has a relatively low level compared to the other end. This is to allow the scum (S) introduced into the scum collection pipe 10 to be naturally discharged to the outside along the water introduced together without external help.

The tilt α of the scum collection tube 10 may be achieved by configuring the tube itself in the form of a fine taper, or as shown, may be achieved by inclining the scum collection tube 10.

Here, the scum inlet 11 should be arranged in parallel with the surface of the water in the installed state. When the scum collection tube 10 is installed inclined, the scum inlet 11 has the same slope α in the opposite direction to the inclination direction of the scum collection tube 10. It is formed to be inclined.

On the other hand, the scum collection pipe 10 may be fixed so that the scum inlet 11 is located on the surface of the water, but in this case, the amount of the treated water flowing out to the outside becomes unnecessarily large, thereby reducing the purification efficiency of the constant.

Accordingly, the scum collection pipe 10 pivots so that both ends thereof can be inverted in a predetermined angle range with respect to the wall W of the coagulation paper B so that the scum inlet 11 can be positioned at the upper side apart from the water surface. It is supported, and the other end is provided with a handle 13 for selectively rotating the scum collection pipe (10).

Of course, such a handle 13 may be replaced by a motor (not shown) that can be inverted in a predetermined angle range as necessary.

For example, when the scum inlet 11 is located on the surface of the water, the scum discharge port 12 is eccentrically formed with the scum collection pipe 10 so as to be positioned above the water, and only when the scum inlet 11 is discharged. As the collection pipe 10 is inverted, it matches with the scum discharge hole H provided in the wall W of the aggregation paper B. As shown in FIG.

The scum conveying means 20 may be configured in various forms, for example, in the form of a conveyor circulating between the scum collection pipe 10 and the agglomerator C provided in the coagulation paper B. Can be configured.

To this end, the scum conveying means 20 is disposed at intervals in the longitudinal direction of the scum collecting pipe 10 and rotates on a pair of chains 21 that rotate and rotate on the wall W of the flocculation paper B. A plurality of sprocket wheels 22 and a plurality of sprocket wheels 22 which are supported so as to be coupled and guided so that each chain 21 circulates in a triangular shape and are arranged at regular intervals along the length direction of the chain 21 so that both ends 21 are connected to both chains 21. It is composed of a plurality of blades 23 for transferring the scum (S) on the water surface to the scum collection pipe 10 by being fixed to).

Here, the reason that the blades 23 are directly fixed to each chain 21 after the two chains 21 are arranged at intervals is that the scum transfer means 20 flows the treated water in the flocculation paper B. This is to minimize the impact on the system.

Since the blade 23 must be able to pull the scum S present on the water surface toward the scum collection tube 10, the blade 23 is fixed so as to protrude appropriately from the outside of the chain 21 so that its free end is a certain length above the water surface. Protrudes as much.

On the other hand, the scum conveying means 20 is preferably arranged side by side along the longitudinal direction of the scum collection pipe 10, for example, two sprocket wheels 22 of each scum conveying means 20 The axis of rotation 24 is shared, each of which is made of a nonmetallic material.

The drive means 30 may consist of a motor (not shown) connected to the rotational shaft 24 of any one of the sprocket wheels 22 of the scum transfer means 20, but preferably consists of an agglomerator (C).

To this end, driving sprocket wheels 31 are provided on the rotary shaft 24 of the agglomerator C and one of the rotary shafts 24 of the scum transfer means 20, respectively, to drive the respective sprocket wheels 31 to the driving chain 32. Connect and configure.

The remaining code T is the scum container provided in the coagulation paper B, and M is the coagulator driving motor.

Next, the operation of the water treatment system scum removing apparatus according to the present invention configured as described above will be described with reference to FIGS. 6A to 6C.

First, in the case of collecting the scum S, as shown in FIG. 6A, the scum collection pipe 10 is rotated counterclockwise by operating the handle 13 so that the scum inlet 11 is aggregated. ) Is placed on the water surface of the treated water.

Then, the scum collection pipe 10 by dragging the scum S floating on the surface of the blades 23 of the scum transfer means 20 connected to the rotation shaft of the agglomerator C by the driving chain 32 and circulating continuously After transporting to the side, it is pushed into the scum inlet 11, whereby the scum S is not easily gathered around the scum collection pipe 10 and is collected very easily therein.

At this time, since the scum discharge port 12 of the scum collection pipe 10 is located above the water surface, the collected scums S are accumulated in the scum collection pipe 10 without being discharged to the outside.

Next, when the scum S is collected to some extent inside the scum collection tube 10, as shown in FIG. 6B, the scum collection tube 10 is rotated by a predetermined angle clockwise through the handle 13.

Then, the scum inlet 11 is positioned above the scum inlet 11 from the surface of the water, and the scum discharge port 12 coincides with the scum discharge hole H provided in the wall W of the coagulation paper B. As shown in FIG. Accordingly, the scum (S) collected toward the scum discharge port 12 having a relatively low level is moved along with the introduced water and discharged to the outer scum bin (T).

Of course, the scum transfer means 20 continues to circulate while discharging the scum S collected in the scum collection pipe 10 to the outside, but the scum S present on the water surface of the coagulation paper B ) Is blocked by the scum collection pipe 10, which is partially submerged in the water, do not escape to the sedimentation basin, etc., is caught in the scum collection pipe 10.

Next, after the discharge of the collected scum (S) is completed, the scum collection pipe 10 is rotated as shown in Figure 6a by placing the scum inlet 11 on the water to collect the scum (S), By repeatedly performing the above-described process, the scum S is collected and removed.

On the other hand, Figure 7 schematically shows another embodiment of the scum removing apparatus according to the present invention. In the structure of the above-mentioned embodiment, this is a gate which can open and close one end of the scum collection pipe 10 to function as a scum discharge port 14, and can be selectively opened and closed by the scum discharge hole H of the coagulation paper B. (gate: G) is installed.

In this embodiment, the collected scum (S) can be discharged more quickly and easily, and although not shown separately, by increasing the diving area of the scum collection pipe 10 to collect and discharge the scum (S) per synagogue You will be able to improve your skills.

As described above, according to the scum removing apparatus of the water treatment system according to the present invention, it is possible to easily collect and remove scum existing on the surface of the treated water, while minimizing the unnecessary outflow of the treated water which is inevitably accompanying scum removal. In addition, the power required to remove scum is also minimized because it utilizes the power of agglomerators that are used in the past.

Therefore, the present invention has a very excellent effect that greatly contributes to the improvement of the reliability and efficiency of the water treatment system.
