Sludge Collector with Sludge Collection Block

The present invention relates to a sludge collector having a sludge collecting block, and more particularly, to a sludge collecting block of a cone type to remove sludge in the sedimentation basin in a simpler and more efficient manner than before. It is about a sludge collector that can solve a problem that requires a lot of time and manpower.

1 is a process diagram of a general sewage treatment plant, the sewage is purified while forming a flow through the inlet dong, the first settling basin, the bioreactor, the final settling basin, the outlet.

The sedimentation basin, especially the longitudinal sedimentation basin, which is essentially used in such a sewage treatment plant (or water purification plant), is a very important process for performing solid-liquid separation.

The primary sedimentation basin, the first sedimentation basin, removes the solids present in the sewage through gravity to protect the subsequent secondary treatment.

Secondary sedimentation basin, which is the final sedimentation basin, separates the effluent from the secondary treatment process into treated water and sludge and finally secures treated water quality. Therefore, it can be regarded as one of the most important processes in the water treatment process.

The sedimentation basin serves to remove sedimentable solids through gravity, which accumulate at the bottom of the sedimentation basin.

At this time, the sedimentation solids can be continuously operated only if the sludge which is a precipitated solid is removed quickly.

If the sludge is not removed, the sludge depth may increase to resuspend with the flow of water, thereby deteriorating the treated water quality, and may not be able to smoothly supply microorganisms to the reaction tank, which is a post-stage process.

There are several ways to remove the sludge.

Referring to these drawings, the sludge collector equipped with the sludge collecting block of the present embodiment can remove sludge in the sedimentation basin 1 in a simpler and more efficient manner than before, which requires a lot of time and manpower for maintenance during operation. In order to solve the problem, the cone type sludge collection block 110, the sludge extraction unit pipe unit 120, the sludge guide 130, and the sludge discharge pipe 140.

FIG. 2 is a view of a sludge collector in which a sludge drawing pump is provided on the outside, and FIG. 3 is a view of a sludge collector in which a sludge suction pump is provided in water in FIG. 2, and in the case of FIG. The sludge collected in the cone-type sludge collection block 110 by the sludge drawing pump to transfer the sludge to the next process is sucked through the sludge withdrawal unit pipe unit 120 is discharged after the structure, in the case of FIG. The sludge collected in the cone-type sludge collection block 110 is sucked by the sludge suction pump 150 through the sludge withdrawal unit pipe unit 120 and then collected in a separate hopper and the sludge drawing pump provided to the outside again. It is a structure to transfer sludge by using.

The sedimentation basin 1 may be a primary sedimentation basin or a secondary sedimentation basin described with reference to FIG. 1, and the cone-type sludge collection block 110 below for sludge withdrawal to remove sludge that is solid precipitated in the sedimentation basin 1. The unit pipe unit 120, the sludge guide 130, and the drawing pipe 140 for sludge discharge is applied.

These structures solve the problem of time-consuming and man- ual maintenance during operation because sludge in the sedimentation basin (1) can be removed in a simpler and more efficient way than conventional chain-flighted sludge collectors and meander sludge collectors. Can be.

First, the cone type sludge collection block 110 is a rectangular block structure and is arranged in a lateral direction in the sedimentation basin 1 so that sludge accumulated in the sedimentation basin 1 is collected therein.

That is, the cone type sludge collection blocks 110 are connected in a lateral direction in the lower region in the sedimentation basin 1 to remove the sludge after gravity sedimentation occurs in the sedimentation basin 1.

As such, the technology for removing sludge after gravity settling in the sedimentation basin 1 is applied, thereby deviating from the conventional scraper method.

In manufacturing the cone type sludge collection block 110 may be considered a polygonal shape other than a rectangular shape.

However, considering that the cone-type sludge collection blocks 110 should be connected laterally as shown in FIGS. 2 and 3, the cone-type sludge collection blocks 110 are preferably rectangular block structures as shown. .

The cone type sludge collection block 110 has a collection space formed therein so that sludge accumulated in the sedimentation basin 1 is collected, and a block body 111 having a plurality of communication holes 112 formed at a side thereof, and a block body. The first sludge is formed in the upper portion of the 111 and is formed concave in the cone (cone type) so that the sludge is collected into the collection space in the block body 111, the first sludge falling in communication with the collection space in the block body 111 in the center And a first cone type recess 113 in which the hole 114 is formed.

In FIG. 8, although the communication hole 112 is formed only on one side of the block body 111, the communication hole 112 may be formed on both side surfaces of the block body 111.

Accordingly, as the communication holes 112 of the block body 111 communicate with each other as shown in FIGS. 2 and 3, sludge that accumulates in the collection space in the block body 111 gathers toward the unit pipe units 120 for sludge extraction and discharges for sludge discharge. It may be discharged through the tube 140.

As the first cone type recess 113 has a shape inclined downward toward the first sludge dropping hole 114 in the center, the sludge falling toward the first cone type recess 113 is lowered along the inclined surface and the first Through the sludge drop hole 114 may be collected into the collection space in the block body 111.

In the present embodiment, the first cone type recess 113 has a concave quadrangular pyramid shape, but may be applied in a concave triangular pyramid, a concave cone, or the like. Therefore, the scope of the present invention can not be limited to the shape of the drawings.

For reference, as illustrated in FIG. 10, a foreign material inflow blocking grating 170 may be coupled to a region of the first cone type recess 113 of the block body 111.

The foreign material inflow blocking grating 170 is coupled to the area of the first cone type recess 113 of the block body 111 to block foreign matter from entering the block body 111.

A plurality of holes 171 are formed at the side surface of the foreign matter inflow blocking grating 170 manufactured in a quadrangular pyramid shape. Therefore, only sludge smaller than the size of the plurality of holes 171 may flow through the holes 171 of the foreign matter inflow blocking grating 170 and may face the first cone-type recess 113.

In FIG. 10, the foreign matter inlet blocking grating 170 is illustrated as being formed in a quadrangular pyramid shape, but is not limited to the illustrated form, and is formed in a flat mesh shape to be detachably disposed on the cone type sludge collection block 110. Can be. Therefore, it may be advantageous to maintain the sludge collector according to the present invention as well as blocking foreign matters while the operator moves from the cone type sludge collection block 110. In addition, the foreign material inlet blocking grating 170 may be provided not only on the cone type sludge collection block 110 but also on the sludge guide 130 to be described later.

Next, the sludge withdrawal unit pipe unit 120 is connected to a pair of cone-type sludge collection block 110 adjacent to each other by a pair of cone-type sludge collecting blocks 110 adjacent to each other at a spacing interval. The sludge collection block 110 is a pipe structure of the unit size for withdrawing the sludge collected in.

In the present embodiment, one unit pipe unit 120 for sludge withdrawal connects them between a pair of cone type sludge collection block 110.

And the unit pipe unit 120 for sludge withdrawal having a unit size is continuously connected along the longitudinal direction. In the connection, a pipe coupling or the like may be used, and the illustration is omitted for convenience.

The sludge withdrawal unit pipe unit 120 is provided with a pair of pipe arms 121 inserted into the communication hole 112 of the pair of cone-type sludge collection block adjacent to each other.

Next, the sludge guide 130 is coupled to the upper portion of the sludge withdrawal unit pipe unit 120 serves to guide the sludge falling from the corresponding position to the sludge withdrawal unit pipe unit 120.

As described above, a large number of cone type sludge collection blocks 110 are laterally connected, but the area in which the sludge withdrawal unit pipe unit 120 is disposed is inevitably spaced apart from the cone type sludge collection blocks 110. Cone type sludge collection block 110 is provided with a plurality of sludge guides 130 to receive the sludge falling into the space is formed spaced apart to send the sludge withdrawal unit pipe unit 120.

The sludge guide 130 is formed in the guide body 131 and the concave type (cone type) in the upper portion of the guide body 131, the second cone type in which the second sludge drop hole 133 is formed in the center The second sludge dropping hole of the concave portion 132 and the upper through hole 122 of the unit pipe unit 120 for sludge withdrawal is provided under the guide body 131. Sludge delivery pipe 134 for transmitting the sludge introduced through the 133 to the sludge withdrawal unit pipe unit 120.

Similar to the structure of the cone type sludge collection block 110, the second cone type recess 132 of the sludge guide 130 has a form inclined downward toward the second sludge dropping hole 133 in the center to form the second cone type. The sludge falling toward the concave portion 132 may be transferred along the inclined surface to the sludge withdrawal unit pipe unit 120 via the sludge delivery pipe 134 through the second sludge dropping hole 133.

Finally, the sludge discharge drawing pipe 140 is connected to one side of the plurality of sludge withdrawal unit pipe unit 120 connected to each other serves to discharge the sludge to the outside of the sedimentation basin (1).

In other words, the sludge discharge drawing pipe 140 is collected through the cone-type sludge collection blocks 110 and the sludge guides 130 to be passed to the sludge withdrawal unit pipe unit 120 to settle the sludge (1). Pipe structure to discharge to the outside.

The sludge discharge drawing pipe 140 is the main drawing pipe portion 141 connected to the sludge withdrawal unit pipe unit 120, one end thereof is in communication with the main drawing pipe portion 141 and the other end of the sedimentation basin (1) It includes an outer sludge drawing pump connecting pipe portion 142 extending to the outside.

The diameters of the main drawing pipe part 141 and the external sludge drawing pump connecting pipe part 142 including the aforementioned sludge withdrawal unit pipe unit 120 may be the same or different. In addition, although not shown in the drawings, the main drawing pipe part 141 and the external sludge drawing pump connecting pipe part 142 are provided with a valve for controlling the flow of sludge, and the sludge drawing pump connecting pipe part 142 is provided with a surplus sludge. External sludge drawing pump (not shown) for sending to the reaction tank and the concentration tank is combined. Therefore, the discharge of sludge can be controlled by the valve and the pump.

The main drawing pipe 141 has a curved shape, that is, a non-linear shape, and the sludge suction pump 150 may be connected to the main drawing pipe 141 as shown in FIG. 3.

As the sludge suction pump 150 is operated, the sludge collected through the cone-type sludge collection blocks 110 and the sludge guide 130 by the force and transmitted to the unit pipe unit 120 for sludge withdrawal is deposited. It can be discharged outside of 1).

For reference, since the external sludge drawing pump (not shown) is configured in the sedimentation basin 1 anyway, the cone type sludge collection block 110, the sludge withdrawal unit pipe unit 120, the sludge guide 130 as in the present embodiment ), And when applying the structure including the discharge pipe 140 for sludge discharge to the sedimentation basin (1), sludge can be removed without a separate power as before.

In other words, in the past, a separate power source was required to drive the chain flight and also to drive the scraper. However, in the present embodiment, an external sludge drawing pump (not shown) originally provided on the outside of the sedimentation basin 1 is used. Because of this, no power source is required.

In the present embodiment, when the hopper 2 collecting the sludge is present in the sedimentation basin 1, the discharge pipe 140 for sludge discharge further includes a sludge suction head 143 for the hopper.

In other words, the hopper sludge suction head 143 disposed in the sedimentation basin hopper 2 is further connected to the main drawing pipe part 141.

Hopper sludge suction head 143 having a plurality of sludge suction through holes (143a) is connected to the end of the main drawing pipe 141, disposed in the sedimentation basin hopper (2) formed on one side of the sedimentation basin (1) It serves to suck the sludge in the hopper (2). That is, since the suction force of the external sludge drawing pump (not shown) also acts on the hopper sludge suction head 143, the sludge accumulated in the clarifier hopper 2 is sucked through the suction holes 143a of the hopper sludge suction head 143. It can be discharged to the outside of the sedimentation basin (1) through the external sludge drawing pump connecting pipe 142.

By this configuration, when the external sludge drawing pump (not shown) is operated through the cone-type sludge collection block 110 and the sludge guide 130 by the force to the sludge withdrawal unit pipe units 120 Sludge conveyed may be discharged to the outside of the settling basin 1 through the main drawing pipe part 141 and the external sludge drawing pump connecting pipe part 142, and in addition, the settling hopper 2 due to the sludge suction head 143 for the hopper. Sludge in) may also be discharged to the outside of the sedimentation basin 1 through the external sludge drawing pump connecting pipe 142.

In addition, in the case of a wide sedimentation basin having a large width and length as shown in FIG. 11, the cone type sludge collection block 110, the sludge guide 130, and the sludge withdrawal unit pipe unit 120 are bundled into one bundle. Sludge discharge drawing pipe 140 formed to be formed in a plurality of transverse direction and having a branch pipe-shaped main draw pipe 141 ', an external sludge draw pump connecting pipe 142 and the hopper sludge suction head 143 When connected to a wide settling basin, a sludge collector may be provided.

According to the present embodiment having such a structure and action, it is possible to remove the sludge in the sedimentation basin 1 in a simpler and more efficient manner than before, thereby solving the problem of requiring time and manpower for maintenance during operation. .

Referring to this figure, the sludge collector of this embodiment can also remove the sludge in the sedimentation basin 1 in a simpler and more efficient manner than before, thus solving the problem of time-consuming and labor-intensive maintenance during operation. As a conical sludge collection block 110, a sludge withdrawal unit pipe unit 120, a sludge guide 130, and a sludge discharge pipe 140 is the same as the above-described embodiment .

However, in the present embodiment, the sludge drawing mechanism 160 is applied instead of the external sludge drawing pump (not shown) and the sludge suction pump 150 as the power source.

The sludge drawing mechanism 160 may include a reciprocating pump 161 and a check valve 162 providing a compressive force according to the reciprocating motion, in particular, the check valve 162 is a reverse flow of the sludge discharged out of the settling basin 1 It helps to prevent.

Even if the structure of the present embodiment is applied, it is possible to remove the sludge in the sedimentation basin 1 in a simpler and more efficient manner than before, thus solving the problem of requiring a lot of time and manpower for maintenance during operation.

Referring to this figure, in the present embodiment, the funnel-shaped cone cap 180 having a top and bottom opening is coupled to the first sludge dropping holes 114 of the cone type sludge collection blocks 110.

The cone type sludge collection block 110 is different in length and number depending on the length and width of the sedimentation basin 1, the cone type sludge collection block 110 adjacent to the sludge suction pump 150 during the operation of the sludge suction pump 150. ) Will take a lot of sludge withdrawal pressure, the farther the sludge suction pump 150 will take less sludge withdrawal pressure.

This is a phenomenon in which the sludge suction pump 150 is inevitably generated to be provided on one side of the sedimentation basin 1, and sludge withdrawal is smooth and uniform to all the cone type sludge collection blocks 110 installed in the sedimentation basin 1. The funnel-shaped cone cap 180 is opened and coupled to the first sludge dropping holes 114 of the cone-type sludge collecting blocks 110 to apply pressure.

At this time, the upper and lower cone caps 180 are gradually enlarged as the opening diameter is gradually wider from the cone type sludge collection block 110 adjacent to the sludge discharge drawing tube 140 or the sludge suction pump 150. Is formed. For example, the opening diameter of the cone cap 180 close to the sludge discharge drawing tube 140 or the sludge suction pump 150 is narrow and is far from the sludge discharge drawing tube 140 or the sludge suction pump 150. The opening diameter of the 180 may be formed to be wide, and through this structure, all the cone-type sludge collection blocks 110 installed in the sedimentation basin 1 may be subjected to a smooth and uniform sludge drawing pressure as a whole. At this time, the opening diameter of the cone caps 180 may be adjusted by step adjustment according to the computer design.

Referring to this figure, in the present embodiment, disposed in one side of the sedimentation basin (1), the discharge of the sludge suction pump when the sludge suction according to the operation of the sludge suction pump 150 in front of the rectifying wall (3) into which the sludge is introduced The settling baffle 190 is further provided to prevent the sludge precipitated by the discharge flow rate of the pipe 151 to rise.

In other words, when the sludge suction according to the operation of the sludge suction pump 150, the discharge flow rate of the discharge pipe 151 for the sludge suction pump is fast, which may cause the problem of floating the sludge, which is sludge for effective sedimentation of the sludge By attaching the settling baffle 190 to the front end of the rectifying wall (3) into which the flow rate of the rectifying wall (3) and the flow rate discharged from the sludge suction pump 150 can be provided more effectively sludge sedimentation effect and As a result, it is possible to destroy the scum chunks accumulated on the top.

In such a structure, it is effective to attach the settling baffle 190 even when the sludge suction pump 150 as well as the sludge drawing mechanism 160 (see FIG. 12) having a large discharge pressure are used.

As described above, the present invention is not limited to the described embodiments, and various modifications and changes can be made without departing from the spirit and scope of the present invention, which will be apparent to those skilled in the art. Therefore, such modifications or variations will have to be belong to the claims of the present invention.
