The present invention relates to a device for collecting sludge and suspended matter in the sedimentation basin, and more particularly, the sedimentation sludge at the bottom and the floating surface of the water by using a new type of integrated scraper that can slide vertically while reciprocating forward and backward in the sedimentation basin. It relates to a vertical slide sludge collection device that can be effectively collected at the same time.

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.

The sludge removal device is a sludge removal device that collects and collects sludge from the bottom of the sedimentation basin while it is rotated by the driving force of the rotating device, and is installed at a position where the full water level of the wastewater is linked to the sludge removal device. It is equipped with a scum removal device for removing small floating foreign matter, that is, scum.

The applicant has applied for and registered Utility Model Registration No. 20-0427920 (Ratchet type sludge / scum removal device) in connection with the contents of the present invention.

However, in the case of the above patent, since the scraper for collecting sludge and scum (floating material) is towed by a separate wire rope, there are many problems in exerting two functions with one driving device.

In addition, since the scraper is rotated and restrained by the ratchet gear, wear or fracture of the ratchet gear occurs due to its own weight, and the float container is also fixed, and thus has a disadvantage in that it is difficult to discharge.

On the other hand, there is a bridge running type existing equipment for collecting the floating at the same time.

This bridge driving type has been introduced in foreign countries and has been installed and used a lot in the early days. The railroad rails are installed on both sides of the rectangular sedimentation basin structure over the entire length, and the driving wheels are mounted on the huge bridges to reciprocate.

However, the existing sludge collection facilities as described above have the following problems.

First, in driving a wire rope of two strands with one driving device, normal operation is impossible because the conveying distance of the scraper is frequently changed due to the difference between friction and friction of the rope.

Second, the scraper restraint device composed of ratchet gear is difficult to adjust the rotation angle limit, and the wear and breakage of ratchet gear occurs due to the collision caused by its own weight when the scraper rotates.

Third, since the cross section of the guide rail is a "c" shape, the sediment accumulates in the horizontal part, the inner part, and the corner part, so that there is a rot injury.

Fourth, since it is difficult to detect the position of the scraper for removing the sediment in the water, adjusting only the scraper for removing the suspended matter on the water causes a lot of problems in removing the sludge from the bottom.

Fifth, since each facility for removing the sludge on the water surface and sludge in the bottom of the sedimentation basin must be provided separately, the overall size of the device is large and there is a lot of power consumption disadvantages.

Sixth, in the case of the traveling bridge type, the running rail is worn and the surroundings are contaminated with rust, etc., and there is a problem that hurts the aesthetics.

Therefore, the present invention has been devised in view of the above, and in order to simultaneously collect the sediment sludge at the bottom and the floating surface of the water generated in a rectangular sedimentation basin in a water treatment plant or a sewage treatment plant, the scraper is vertically lowered at the time of collecting the target. In the process of reversing, the integrated scraper in which the scraper rises vertically can be effectively collected at the same time to effectively collect the sedimentation sludge and the suspended solids, and the overall structure can be simplified and lightened. Overloading factors can be eliminated, and the structural part of the scraper can be easily configured, which can reduce the economic cost.

One side of the compression roller 10 is provided with a sprocket to transfer the rotational force to each other in conjunction with each other in a chain, the sprocket and the drive motor 11 is connected to the shaft of any one of the compression rollers of each of the compression roller chain Since the rollers are electrically connected to each other, the wire ropes 12 placed in a pressurized state between the upper and lower compression rollers are rotated by the operation of the driving motor 11 in accordance with the rotation direction of the compression rollers. The bite is pulled to one side in one direction, and the scraper device to be described later can be moved by the wire rope which is finally pulled and thus moved. It is. At this time, the upper compression rollers are preferably installed in a structure that can flow up and down so that the length and tension of the wire rope can be changed.

In addition, inside the settling basin, a plurality of return sheaves 13 of a structure rotatable freely in positions adjacent to the floor are 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 only the tension separately.

This configuration is not wound much because the wire rope is hung on the compression roller with zigzag up and down compared to the drum method in which the wire rope is wound around several tens of meters. There is an advantage to it.

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

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, the wire rope 12, which is in the form of a closed curve, extends from the plurality of compression rollers 10, which are the wire feeding means, to the vicinity of the floor, and the wire ropes 12 extending in this way are each return sheave 13 Supported in the form spanning) is connected to the side of the sprapper device 15 disposed below the sedimentation basin can be moved in the form of towing the scraper device.

For example, the wire rope 12 extends through a plurality of compression rollers 10 serving as wire feeding means to form a closed curve while passing through the front return sheave 13 and the rear return sheave 13. The wire rope 12 is pulled in one direction by the forward rotation or the reverse rotation of the plurality of compression rollers 10, which are wire feeding means, connected to the front and the rear of the scraper device 15 in the section between the closed curves. As a result, the scraper device 15 fixedly connected to the wire rope 12 may move forward or backward in the settling basin as the wire rope 12 proceeds.

In addition, the both sides of the settling basin is provided with a guide rail 14 horizontally formed in the form of an inequality channel having a cross-section ">" and "<" shape, the guide rail 14 at this time is located near the floor It will be able to guide the movement of the scraper device 15 there.

In other words, the scraper device 15 is guided by the guide rails 14 opposed to each other and moved along a predetermined path to remove sludge from the bottom and floats on the surface of the water.

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

In addition, a means for guiding the rise and fall of the scraper device 15, that is, the elevating guide rail 16, is installed back and forth in the form of being supported on the wall or the like, and the elevating guide rail 16 is provided. ) Serves to induce the rise and fall of the scraper device 15, substantially the scraper (19a), (19b) using the front and rear inclined portion.

For example, when the scraper is moving forward to collect the object, that is, sludge collection and float collection, the scraper may be normally vertically lowered, and during the reverse process, the guide roller in the scraper is not lowered. Since the contents rail 16 is to be climbed, the scraper at this time can proceed to the rear in a vertically elevated state, and when it leaves the elevating guide rail, the inclined portion of the elevating guide rail is guided in the state almost advanced to the rear. As it falls down, the scraper can again be in the vertically lowered state.

In other words, the scraper can be collected by scraping the sludge on the bottom only in the case of going forward, and proceeds to the bottom in the situation returning to the back, so that the sludge of the bottom is never taken back.

Figure 3 is a front view showing an example of the scraper device in the vertical slide sludge collection device according to an embodiment of the present invention.

As shown in FIG. 3, the main body of the scraper device 15 is a saddle 17 composed of a horizontal member and a vertical member structure having an approximately "H" shape.

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

Particularly, in the case of the roller 18, the top and bottom two are laid down in a pair and are configured in a combination of left and right rollers contacting the side surfaces of the guide rails 14 to ensure a more stable movement of the saddle 17. Will be.

The scraper for removing sludge and floats of the present invention consists of an integral combination of an upper scraper 19a for removing float on the water surface and a lower scraper 19b for removing sludge from the bottom, and the saddle 17 The sludge on the bottom of the sedimentation basin can be scraped while being supported on the horizontal member of the sludge, and the float on the water surface can be removed.

Therefore, since there is no interference member such as a floor rail, which is a path for existing trolleys, the sludge on the bottom surface can be cleaned and collected.

At this time, the scrapers 19a and 19b are formed in a plate shape having a predetermined area, and the upper end portion in the standing state extends to the upper surface of the water and the lower end portion can contact the bottom of the sedimentation basin.

In particular, the scrapers 19a and 19b are supported by a structure that can be raised or lowered in the forward and backward operation.

To this end, the tubular housing 24 is vertically installed on the horizontal member of the saddle 17, the slide shaft 21 is formed on one side of the rear side of the scraper (19a), (19b), the slide shaft at this time As the 21 is coupled to the housing 24 in a slidable structure, the scrapers 19a and 19b can be vertically slidable.

In addition, the upper end of the lower scraper 19b is provided with a guide roller 20, and the guide roller 20 is guided up and down by the lifting guide rail 16 in which the guide roller 20 is located in the sedimentation basin. You can go up or down.

For example, the scraper floats from the floor at a certain height while the guide roller 20 is in contact with the elevating guide rail 16 for the first time, and the guide roller is off the elevating guide rail. During the process, the scraper comes into contact with the bottom of the settler.

To this end, the tip of the elevating guide rail 16 is inclined downward and is formed lower than the guide roller, and the upper and lower points are preferably installed to be horizontally extended to a predetermined length, that is, to the rear of the settling basin. Accordingly, the guide roller is able to move to the rear of the settling basin in a state in which the predetermined section is raised, and descends by its own load when it moves out of the lifting guide rail 16.

At this time, the lower portion of the scraper device descending by the weight may be impacted by hitting the bottom of the sedimentation basin, and thus, the time from the lifting guide rail to the rear of the sedimentation basin before the scraper reaches the floor may be adjusted and the scraper may bottom. Shock absorbing means for absorbing the impact of the surface is provided.

To this end, as shown in (b) of FIG. 3, a piston rod 25 extending vertically is formed at one side of the scraper, and a piston rod having a water entry hole 27 at the lower end at the saddle 17 side. It is provided with the cylinder 26 which accommodates 25.

Accordingly, as the piston rod 25 rises when the scrapers 19a and 19b are raised, water is filled in the cylinder 26 by the suction force at this time, and the scraper device 15 proceeds backward. Then, when the scrapers 19a and 19b are lowered by their own weight again, the piston rod 25 is subjected to resistance by the water filled in the cylinder 26 at this time, that is, the piston rod 25 As it is pushed down gradually, the scrapers 19a and 19b are brought into contact with the bottom at the rear of the sedimentation basin and can be seated at the bottom of the sedimentation basin without impact.

More preferably, it is preferable to install a stopper 28 which can hold the lifting guide rail 16 of the scraper while lifting up to the rear at the time of lifting. As an example, the locking means is provided on the fixed housing and the slide shaft coupled thereto, and the lifting means is lifted by the locking at the time of lifting, and is forced by the lifting guide rail 16 on the rear side to be lowered.

In addition, as shown in Figure 4, here shows an example of performing the buffer function using the housing and the slide shaft coupled to each other for the slide guide of the scraper.

To this end, the housing 24 is formed in the form of a cylinder having a water entry hole 27 on one side of the lower side, the slide shaft 21 is slide coupled to the housing 24 to serve as a piston rod do.

Here too, water is filled in the housing 24 by the rise of the slide shaft 21 when the scrapers 19a and 19b are raised, and the slide shaft 21 when the scrapers 19a and 19b are lowered. Receiving the resistance of the water it is possible to effect the buffer of the scraper (19a, 19b).

Therefore, looking at the form to remove sludge and suspended matter using the sludge collection device of the present invention configured as described above are as follows.

Sludge and sludge floating on the surface of the sedimentation basin can be removed at the same time by an integrated scraper device.

To this end, when the plurality of compression rollers 11, which are wire feeding means, are rotated by the operation of the driving motor 11, the wire rope 12 which is bitten by the plurality of compression rollers at this time and extends near the floor is The scraper device 15 fixed and interlocked to the wire rope 12 moves forward and backward from the bottom and the surface of the sedimentation basin, and the floating sludge on the bottom and the floating surface on the water surface are integrated. ), (19b) by scraping or kicking out, it is possible to remove the sludge and suspended solids together.

That is, in the case of removing the float, the float floating on the water surface can be removed in the form of being attracted to the float collecting part 22 on one side of the sedimentation basin, and in the case of sludge removal, the sludge of the bottom is scraped through the bottom scraper when going to the front. While scraping the sludge can be removed in the form of scraping toward the collecting portion (23).

At this time, the scraper device 15 has a vertically slidable structure, so that the scraper 19a, 19b moves in a lifted state when moved to the rear of the sedimentation basin, so that the sludge or floating object is not driven to the opposite side of the collecting part.

In this way, since the scraper device can repeatedly move between the front and the rear of the sedimentation basin to remove floats and sludge at the same time, it is possible to effectively remove sludge and suspended matter in the water of the sedimentation basin and the surface of the water, and to increase the treatment efficiency at this time. It becomes possible.

As described above, the present invention simplifies the overall structure of the facility by implementing a new type of sludge collecting device including an integrated scraper that simultaneously collects the bottom sediment and the surface floating water while reciprocating the longitudinal direction of the rectangular sedimentation basin. At the same time, it is possible to reduce the load on the equipment, and to reduce the overload occurring during operation without causing the trouble of the equipment, and to constantly check the position of the scraper. It is effective in the efficient operation and management of equipment related to the effects such as maintenance and maintenance, and furthermore, it is effective in efficiently and economically treating sludge and suspended matter generated in the water treatment process or sewage treatment process. .
