The present invention relates to a sludge / scum removal device capable of removing sludge or suspended matter generated in an improved settler, such as a water purification plant or a sewage treatment plant, and more particularly, a wire rope driving means, a saddle with a ratchet scraper, and the like. By constructing a ratchet sludge / scum collection system of a new type, including sludge, it is possible to effectively and economically treat sludge and scum generated in a water treatment process or sewage treatment process, and the overall structure is simple and lightweight. The present invention relates to a ratchet sludge / scum removal device of a wastewater treatment plant that can reduce operational load and efficiently operate or manage a facility such as maintenance.

In general, a circular sedimentation or improved sedimentation system is a facility for treating water in a short time while separating and discharging a large amount of wastewater into sediment sludge and scum, and is widely used in sedimentation basins and concentration tanks in water purification plants, sewage treatment plants, and wastewater treatment plants.

These sludges are sludge removal devices that collect and collect sewage sludge from the bottom of the sedimentation basin while rotating by the driving force of the rotating device, and are installed at positions where the water level is full of wastewater while being interlocked with the sludge removal devices. A scum removal device is installed for removing floating foreign matter, that is, scum.

The applicant has filed and registered Patent No. 10-0365304 (Sliding Shoe Sludge Collection Device) in relation to the contents of the present invention. However, the rail is installed on the floor and the sludge is collected by moving the wheel using the wheels.There is a limit to completely collect the floor sludge with the scraper due to the interference of the rails installed on the floor. There was a downside.

In addition, the sludge removal apparatus generally includes a truss structure in which a plurality of angles and plates are welded, including components such as a sludge arm or a sludge blade, and a scum skimmer or a scum blade. It is composed of a structure that is integrally welded to the sludge removal apparatus, including, and the wire drive unit is a drum form is wound around a few tens of meters of wire is composed of a fairly large volume.

However, such conventional sludge and scum treatment facilities have the following problems.

First, since the truss structure for constructing the sludge removal device is a structure composed of welding of multiple angles and plates, it is an enormous weight body that must simultaneously support not only its own weight but also the weight for supporting the scum removal device. Since the apparatus is a rotating body, not a fixed body, there is a high possibility that structural stability may be seriously threatened while large loads or stresses are applied to a plurality of wires or casters for supporting it.

Second, as the sludge removal apparatus is composed of the welding structure of the angle and the plate as described above, not only the structure is complicated, but also the assembly time and installation time is excessive, and also the heavy weight body maintenance is difficult to maintain significantly have.

Third, since the sludge removal apparatus including the scum removal apparatus is a considerable weight, the initial load during driving is large and the driving method is complicated.

Fourth, the drive unit is wound around a few tens of meters of wire is composed of a considerably large volume, there is a disadvantage that the problem of the wire tangled or twisted during operation to provide a cause of malfunction.

Accordingly, the present invention has been made in view of the above, by implementing a new type of sludge / scum collection system that can simultaneously remove the sludge and scum while proceeding along the water and the surface of the sedimentation basin, The overall structure can be simplified and reduced in weight, and since there is no configuration of floor rails and trolleys, the interference caused by them can be completely eliminated, so that the structural sludge as well as the floor sludge can be completely removed. It is possible to reduce the load and to efficiently manage and manage the facilities such as maintenance, and ultimately to effectively and economically treat sludge and scum generated in the water treatment process or sewage treatment process. It is an object of the present invention to provide an apparatus for removing sludge / scum.

The present invention for achieving the above object is installed on one side of the sedimentation basin and a plurality of compression rollers and the wire feeding means for operating the wire rope while alternately pulling the wire rope extending in both directions in the water and the water surface, respectively A driving motor for operation, a plurality of return sheaves for guiding each of the wire ropes extending from the driving drum side to a predetermined trajectory, and respective guide rails in the water of the sedimentation basin and on the water surface. And a sludge remover for removing sludge in the water using a scraper and a scum remover for removing the scum on the water while being guided and pulled by the wire rope and moving back and forth.

In addition, the sludge remover is a bird consisting of a structure of the horizontal member and the vertical member, a plurality of rollers attached to both sides of the vertical member of the birds to ride on the guide rail of the sedimentation basin wall side, and is mounted on the horizontal member of the birds It characterized in that it comprises a plate-shaped scraper that can scrape the sludge of the bottom of the clarifier.

In addition, the roller is characterized by consisting of the left and right rollers standing upright and lying on the side and in contact with the upper and lower surfaces of the guide rail to contact the side of the guide rail.

In addition, the scraper is supported by the ratchet mechanism can be flipped in one direction, it is characterized in that the bending in the opposite direction can be restrained.

In addition, the scum remover is a bird consisting of a structure of the horizontal member and the vertical member, a plurality of rollers attached to both sides of the vertical member of the birds to ride on the guide rail of the sedimentation basin wall side, and is mounted on the horizontal member of the birds It is characterized in that it comprises a rubber plate-type scraper to remove the scum of the sedimentation basin level.

In addition, the inside of the sedimentation basin is characterized in that the scraper roll over / restore guide is disposed on the front and rear sides of the movement trajectory line of the scraper having the sludge eliminator to induce the roll over and restore.

Hereinafter, an embodiment of the sludge / scum removal device of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 is a side view showing a ratchet sludge / scum removal device according to an embodiment of the present invention, Figure 2 is a plan view showing a ratchet sludge / scum removal apparatus according to an embodiment of the present invention.

As shown in Fig. 1 and 2, a plurality of compression rollers 10 are installed on the outer periphery of the sedimentation basin containing a certain amount of sewage or wastewater by a wire feeding means supported by a rotatable structure on the frame structure. One side is provided with a drive motor 11 that can rotate each compression roller 10 at the same time through a chain transmission means.

At this time, the drive motor 11 is a motor capable of forward and reverse operation, it is possible to rotate a plurality of compression rollers 10 in the forward or reverse direction.

For example, as shown in Figure 5, parallel to the wire rope 12 running in a linear trajectory, a plurality of compression rollers 10 are arranged in a row by pairing up and down by wire feeding means, each One side of the compression roller 10 is fitted with gears that are engaged with each other, and the sprocket and the driving motor 11 connected to the shaft of one of the compression rollers of each of the compression rollers are electrically connected through the chain. Therefore, when each of the compression rollers is rotated by the operation of the driving motor 11, the wire rope 12 placed in a pressurized state between the up and down compression rollers is bitten in accordance with the rotational direction of the compression rollers, thereby being one of the one directions. The scum remover and the sludge remover, which will be described later, may be moved by the wire rope which is thus pulled and thus moved.

In addition, inside the settling basin, a plurality of return sheaves 13 of a structure rotatable freely in positions adjacent to the floor and close to the water surface are respectively installed in a form of being supported by a bracket or the like. At this time, any one of the return sheave 13 may be provided with a tension (not shown) to prevent the sagging of the wire rope and adjust the tension, it may be configured separately only the tension.

This configuration is simple compared to the drum method of the wire rope wound around several tens of meters, and only a plurality of compression rollers can be configured as a wire feeding means, so the configuration of the driving unit is simple and the overall volume can be minimized. There is an advantage to it.

Return sheaves may be installed at the front and back, respectively, near the bottom of the clarifier and near the surface of the water.

At this time, the return sheave 13 is a means for guiding the trajectory of the wire rope 12, and an appropriate number and installation positions may be determined according to the layout related to the trajectory of the wire rope according to the surrounding installation conditions.

In addition, two pairs of wire ropes 12 which are in the form of one closed curve from the plurality of compression rollers 10, which are the wire feeding means, respectively, are extended in the vicinity of the bottom and the surface of the water, respectively, and the pair of wire ropes 12 thus extended ) Is supported in the form spanning each return sheave 13 and connected to the scum remover 16 side and the sludge remover 15 side respectively disposed above and below the sedimentation basin to move each remover. I can give it.

For example, each pair of wire ropes 12 extends through a plurality of compression rollers 10, which are wire feeding means, to pass a closed curve while passing through the front return sheave 13 and the rear return sheave 13, respectively. It is formed, and is connected to the scum remover 16 or the sludge remover 15 in the interval between these closed curves, the wire rope 12 by the forward rotation or the reverse rotation of the plurality of compression rollers 10 which is a wire feed means It is pulled in one direction, so that the scum remover 16 and the sludge remover 15 fixedly connected to the wire rope 12 can move forward or backward along the progress of the wire rope 12. .

At this time, the movement of the eliminator can be moved in the opposite direction in the case of two sides when viewed in a plane, that is, one moves forward and the other moves backward.

In addition, the guide rails 14a and 14b formed in a substantially "c" channel form are horizontally installed on both wall surfaces of the settling basin, and the guide rails 14a and 14b at this time are near the bottom and near the water surface, respectively. It is positioned to guide the movement of the sludge remover 15 and scum remover 16 there.

That is, the sludge remover 15 and the scum remover 16 are guided by the guide rails 14a and 14b installed opposite to each other to move along a predetermined path while removing sludge from the bottom and scum from the water surface. .

In addition, the sludge collection unit 23 and the tubular scum collection unit 22 of the concave-type structure are formed on one side of the settling basin, for example, in front of the bottom and the water surface, and the sludge and scum collected therein The can be sent to the outside through a separate processing device (not shown).

In particular, the scum collecting unit 22 is provided with a scum guide plate 24 inclined from the water surface to the collecting unit, so that the rubber plate-shaped scraper 19b of the scum remover 16, which will be described later, rises up here. The collected scum can be naturally pushed into the collecting unit.

In addition, the inside of the sedimentation basin is provided with a scraper roll over / restore guide 21 in the front and rear, respectively, the scraper roll over / restore guide 21 at this time is the movement trajectory of the scraper (19a) of the sludge remover 15 It is disposed on the ship in front and rear, respectively, and serves to induce overturning and restoration of the scraper.

That is, the scraper 19a of the sludge remover 15 can be turned back and lying down while being interfered with the inclined portion of the scraper rollover / restoration guide 21, and can be turned upside down.

3 is a side view showing a sludge remover of the sludge / scum removal device according to an embodiment of the present invention, Figure 4 is a plan view showing a sludge remover of the sludge / scum removal device according to an embodiment of the present invention.

As shown in FIG. 3 and FIG. 4, the specific form of the sludge remover is shown here, but the scum remover may have almost the same structure except that the scraper is slightly different in form or operation. Therefore, the technique of a scum remover mentioned later reveals that it is a technique of a sludge remover.

The main body of the sludge remover 15 is a saddle 17a consisting of a horizontal member and a vertical member structure having an approximately "H" shape.

A plurality of rollers 18a are attached to both sides of the vertical member of the saddle 17a so that the rollers 18a can be used to move between the front and rear of the settler while traveling on the guide rail 14a on the wall of the settler. .

In particular, in the case of the roller (18a) is composed of a combination of the upper and lower rollers standing upright and in contact with the upper and lower surfaces of the guide rail (14a) and the left and right rollers lying on the side and in contact with the side of the guide rail (14a) saddle (17a) The more stable movement state of can be secured.

The scraper 19a, which substantially removes the sludge, is mounted on the horizontal member of the saddle 17a to scrape the sludge from the bottom of the sedimentation basin. The sludge from the cotton can be cleaned and collected.

At this time, the scraper (19a) is in the form of a plate having a predetermined area, the lower end is in contact with the settling basin in the standing state.

In particular, the scraper (19a) is mounted on the side of the horizontal member of the birds in a form supported by the ratchet mechanism 20, and thus can be flipped in one direction and the opposite direction (ie, sludge geography forward direction) As a result, wetting can be constrained.

That is, when birds move forward from the rear of the sedimentation basin, it is possible to maintain the upright posture under the binding force of the ratchet mechanism 20, and when moving from the front to the rear, the ratchet is released to be inclined while being released. It becomes possible.

This is to ensure that the scraper does not scratch the sludge when going to the rear, but only to scrape the sludge when going to the front.

Here, the configuration of the ratchet mechanism 20 is known in the art, not to specifically describe the structure, it is possible to apply a conventional one.

Meanwhile, the scum remover 16 includes saddles 17b and rollers 18b similar to those of the sludge remover, and the scraper 19b is formed of a rubber plate to remove the scum floating on the surface of the scum. It can be removed, approaching the scum collecting unit 22 side bends itself while being able to climb up the inclined surface of the scum induction plate 24 to push the scum up.

Therefore, the form of removing sludge and scum by using the sludge / scum removal apparatus of the present invention configured as described above is as follows.

Sludge accumulated at the bottom of the sedimentation basin and scum floating on the water surface can be removed simultaneously by each sludge and scum remover.

To this end, when the plurality of compression rollers 11, which are wire feed means, are rotated by the operation of the driving motor 11, each pair of compression rollers that are bitten by the plurality of compression rollers at this time and extended to near the water surface and near the bottom, respectively. The wire rope 12 is moved and moved, so that the sludge remover 15 and the scum remover 16 fixed and interlocked to the wire rope 12 move back and forth at the bottom and the water surface of the sedimentation basin, respectively. By scraping or scraping the scum on the surface with each scraper 19a, 19b, the sludge and scum of the sedimentation basin can be removed.

That is, in the case of the scum remover, the scum can be removed by pulling the scum floating on the water to one side, that is, the scum collector 22, and in the case of the sludge eliminator, Sludge may be removed in the form of scraping the sludge toward the sludge collection unit 23.

At this time, since the sludge remover 15 and the scum remover 16 are ratchet driven, the sludge remover 15 is moved in a state in which the spreader 19a is flipped to one side so as not to drive the sludge to the opposite side of the collecting part.

In this way, since the scum remover and the sludge eliminator can be repeatedly moved between the front and the rear of the sedimentation basin at the same time, the sludge and the scum of the sedimentation basin and the water surface can be effectively removed. Efficiency can also be increased.

As described above, the present invention can effectively remove sludge and scum in the water of the sedimentation basin and the water surface by using a wire rope driving method using a plurality of compression rollers, a ratchet scraper, a saddle, etc. as a wire feeding means. By providing a new type of sludge / scum collection system, the driving method can make the volume as small as possible compared to the drum method in which the wire rope is wound, thereby simplifying the overall structure of the facility and reducing the weight. In addition, since there is no floor rail and trolley configuration, the scraper can be completely adhered to the bottom surface to collect sludge, so that the sludge removal effect can be obtained. The efficient operation and management of equipment related to maintenance It is effective, and furthermore, the sludge and scum generated in the water treatment process or the sewage treatment process can be efficiently and economically treated.
