Description

Sludge / Scum collector of wastewater disposal plant}

The present invention relates to a sludge / scum removal apparatus, and more particularly, to a sludge / scum removal apparatus capable of effectively treating sludge and scum generated in an improved sedimentation battery such as a water purification plant or a sewage treatment plant.

In general, a water purification plant is a means of purifying raw water to make clean water, and raw water is to be delivered through a water fountain consisting of a mixing well → a sedimentation basin → a filter paper → a water pumping pump chamber having a landing well → a chemical injection unit and a formation site.

In addition, the sewage treatment plant treats sewage generated at workplaces such as residential areas and factories, and the sewage is purified to about 92 to 95% through a sedimentation basin → aeration tank → a final sedimentation basin, and then sterilized and discharged into a river or sea.

In addition, the sedimentation basin installed in the water purification plant or sewage treatment plant removes floc by using sedimentation separation process. Sludge removal device to remove sludge and scum removal device to remove floe floating on water.

Here, the sludge removal device is to scrape the sludge in the reverse direction of the water stream by a scraper attached to the water cart to discharge to the outside, or to discharge the sludge by driving the Filght connected to the chain installed on the base of the sedimentation basin in the water flow direction. It is.

In addition, the scum removing device is installed to be fixed in the transverse direction to the upper end of the inner wall constituting the sedimentation basin to remove the floating matter floating on the water.

For example, a circular settler or an improved settler 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.

In the case of the sludge removal device, the sludge is collected by the rail installed on the floor and moving the cart using wheels, but it is limited to the complete collection of the sludge by the scraper due to the interference of the rail installed on the floor. There is a significant difficulty in installing the drive unit to be installed outside the water. In addition, when cleaning the needle battery, the trolley and the scraper is located on the bottom surface was not able to perform a clean cleaning.

In addition, most sludge removal devices include truss structures in which a plurality of angles and plates are welded, including components such as sludge arms and sludge blades, and scum skimmers and scum blades. It consists of a structure that is integrally welded to the sludge removal apparatus, including, and the wire drive unit is formed in a drum form of a very large volume is wound around the wire of several tens of meters and connected to the structure installed on the inner bottom surface of the sedimentation basin.

As such, the existing sludge and scum treatment facilities have many problems in terms of function and structure.

For example, the truss structure for constructing the sludge removal device is a structure composed of welding of a plurality of angles and plates, and thus is a massive weight body that must simultaneously support not only its own weight but also the weight for supporting the scum removal device. Since the sludge removal apparatus is not a fixed body but a rotating body, there is a high possibility that structural stability may be seriously threatened while a large load or stress is applied to a plurality of wires or casters for supporting the sludge.

In addition, since the sludge removal apparatus is composed of the weld structure of the angle and plate as described above, not only the structure is complicated, but also the assembly time and installation time is excessive, and the maintenance is very difficult because of the heavy weight.

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

In the case of the drive unit, the wire is wound up to several tens of meters, so that the volume is considerably large, and a problem that the wire is entangled or twisted during operation provides a cause of a malfunction. In addition, the installation work is not easy and complicated because it is connected to the structure installed below the sedimentation basin.

Accordingly, the present invention has been made in view of the above, by implementing a new type of sludge / scum collection system that can efficiently remove sludge and scum simultaneously while proceeding along the water and the surface of the sedimentation basin, respectively, The overall structure of the equipment can be simplified and lighter, and the side guide method outside the water can be applied to completely eliminate interference caused by conventional floor rails and trolleys, thereby removing structural sludge and floor sludge completely. In addition, it can reduce the operational load by applying its own driving method, and can efficiently operate or manage the facilities such as maintenance. Especially, when cleaning in the sedimentation basin, there is no structure that is constrained by moving the sludge scraper to the upper part. Very easy and ultimately the water purification process And there is provided a sludge / scum removal apparatus which can process the sludge and the scum to more effectively and economically generated in the sewage treatment process.

In order to achieve the above object, the sludge / scum removal device provided in the present invention is supported in a form of horizontally extending on a frame moving along two guide rails on both sides of the upper end of the sedimentation basin structure, and two parallel spindles extending vertically from the frame. The sludge scraper and the scum scraper disposed in the water and the water surface of the sedimentation basin structure, respectively, and the drive unit is installed on the frame to operate the entire frame including the sludge scraper and scum scraper, etc. It is done.

Here, the drive unit is in the form of a motor, a rotating shaft which is installed in parallel with it on the frame while being rotated by the motor, sprockets that are engaged with the chain is installed in the upper end of the sedimentation basin structure while being mounted at both ends of the rotating shaft. It is preferred to be configured.

In addition, in the case of the frame is preferably provided with a tapered roller rolls while contacting both sides of the "V" type guide rail to form a certain angle.

The sludge / scum removal device is composed of two vertically parallel feed shafts connected to the sludge scraper and the scum scraper side, and an actuator connected to the feed shaft while being installed on the frame to control the height of the sludge scraper and the scum scraper. It may further include a transfer device.

Sludge / scum removal device provided by the present invention has the following advantages.

First, since it is operated by its own driving means, the scale can be reduced as much as possible, thereby simplifying the overall structure of the facility and realizing light weight.

Second, since the guide rail is installed outside the water to guide the facility, the previous floor rails and trolleys can be completely removed, and thus, the sludge can be completely adhered to the floor to collect sludge. Elimination effect can be obtained.

Third, since the size of the facility as a whole is light, it is possible to efficiently operate or manage the facility in relation to the effect and maintenance, such as securing structural stability and reducing the load on the operation.

Fourth, when cleaning in the sedimentation basin by moving the sludge scraper to the top there is no structure at the bottom in the sedimentation basin can facilitate the washing operation.

Therefore, the above advantages have the effect of efficiently and economically treating the sludge and scum generated in the water treatment process or sewage treatment process.

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

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

1 and 2, the sludge / scum removal device floats on the surface of the sludge and water accumulated in the bottom of the water while moving along the longitudinal direction of the sedimentation basin structure 100 containing a certain amount of sewage or wastewater. It is structured to remove scum at the same time.

Frame 11 of the sludge / scum removal device is disposed across the width direction of the sedimentation basin structure 100, guides the guide rail 10 is installed along the longitudinal direction at both upper ends of the sedimentation basin structure (100) It is to move upon receiving.

To this end, both ends of the frame 11 are provided with at least two roller means, for example four roller means for moving while maintaining balance.

At this time, the roller means, as shown in Figure 3, each of the two rollers in a pair of up and down a constant angle, for example, consisting of a tapered roller 20 combined at an angle of 90 ° "V" type The upper and lower surfaces of the guide rail 10 having a cross section can be rolled stably while being in contact with each other.

Since the guide structure of the roller and the guide rail is a guide structure that can be rolled in the form of the two rollers in engagement with the rail, the frame 11 can be moved stably without any shaking as well as detachment.

The driving unit 15 for the operation of the frame 11 is not installed around the sedimentation basin structure 100, etc., but is formed on a frame 11 so as to move together with the frame 11. .

To this end, the motor 16 is installed about the middle of the length of the frame 11, the rotation shaft 17 is installed side by side along the left and right width direction of the frame (11).

At this time, the rotating shaft 17 is installed in a form supported by a plurality of bearings 23, the motor 16 is connected to the gear transmission means, for example bevel gears to be rotated when the motor is operating. do.

In addition, sprockets 19 are mounted at both ends of the rotary shaft 17, and the sprockets 19 are engaged with the chains 18, which are installed in the longitudinal direction on the upper surface of the upper end of the sedimentation basin structure 100, to roll. It can be in a form that can be.

Accordingly, when the motor 16 operates, the entire frame 11 may move along the longitudinal direction of the settling basin structure 100 by the rotation of the rotary shaft 17 and the sprocket 19.

Here, the cover 24 is covered in the entire section in which the chain 18 is installed, so that a poor contact between the sprocket 19 and the chain 18 due to the inflow of foreign matters can be prevented.

The sludge scraper 13 and the scum scraper 14, which are responsible for substantially removing sludge and scum, are installed in a structure arranged side by side up and down in the water and the water surface in the clarifier structure 100.

That is, two parallel spindles 12 which are supported on the frame 11 side are installed vertically long, and the sludge scraper 13 is connected to the lower ends of the two spindles 12 which are thus installed, and slightly smaller than the middle of the length. The scum scraper 14 is connected and attached to the upper side.

At this time, the main shaft 12 is supported in a slide support 22 which is installed on the frame 11, for example, a slide support 22 that can serve as a guide and move up and down.

Here, the scrapers are in the form of elongated bars, and in the case of the scraper for sludge removal, the scrapers are installed in contact with the bottom surface of the sedimentation basin structure 100 while having a slightly larger width than the scraper for removing the scum.

Particularly, when the sludge scraper 13 and the scum scraper 14 require a predetermined operation such as when the inside of the sedimentation basin structure 100 is inspected or cleaned, the sludge scraper 13 and the scum scraper 14 require a work situation such as when the sludge or the scum scraper is returned. The position (height) can be controlled.

To this end, the frame 11 is provided with two actuators 21b, such as cylinders, on both sides, and two vertically parallel feeds connected to the sludge scraper 13 and the scum scraper 14 on the actuator 21b side. The shaft 21a is connected.

Accordingly, when the actuator 21b is operated, the feed shaft 21a can move up and down, and thus, the sludge scraper 13 and the scum scraper 14 can also move together up and down while being guided by the main shaft 12, The sludge scraper 13 and scum scraper 14 may be dropped from the bottom of the clarifier structure 100 when work is required or upon return.

Therefore, the process of removing sludge and scum using the sludge / scum removal device configured as described above is as follows.

The sludge accumulated on the bottom of the sedimentation basin structure 100 and the scum floating on the water surface may be simultaneously removed by the sludge scraper 13 and the scum scraper 14.

That is, when the rotating shaft 17 is rotated by the operation of the motor 16, the sprocket 19 also rotates to roll the chain 18, the frame 11 is moved under the chain driving force at this time.

Accordingly, the sludge scraper 13 and the scum scraper 14 moves back and forth from the bottom and the surface of the sedimentation basin structure 100 while scraping or scraping the sludge on the bottom and the scum on the water surface, thereby the sedimentation basin structure 100 The sludge and scum inside can be removed.

For example, in the case of the scum scraper 14, the scum floating on the surface of the scum scraper 14 can be removed by driving to one scum collector (not shown), and in the case of the sludge scraper 13, the sludge scraper 13 proceeds to one side to scrape the sludge. It can be removed in the form of driving toward the sludge collector (not shown) at the end of the sedimentation basin structure (100).

At this time, when the sludge scraper 13 and the scum scraper 14 is returned to the rear of the sedimentation basin structure 100, the sludge or scum is driven to the opposite side of the collecting part by moving the scraper and lifting the scraper. There will be no going.

As such, the sludge scraper and the scum scraper can be removed at the front and the back of the sedimentation basin at the same time, so that sludge and scum in the water and the surface of the sedimentation basin structure can be removed at the same time. Can also increase the processing efficiency.

Meanwhile, in the present invention, the driving unit may be adopted as a wire driving method.

Conventionally known wire driving method is inconvenient to install and complicated structure because the wire of the drive unit is connected to the structure installed on the bottom surface in the water, the present invention is a frame moving along the guide rail is located at the upper end of the sedimentation basin structure The installation work is quite advantageous and not complicated.

In particular, such a wire driving method, when not only one settling basin as shown in Fig. 4, but also two settling basins as shown in Fig. 5 by one drive means to alternately transfer the scraper of both settling basins and sludge and scum It is more useful because it can be removed.

To this end, the sludge / scum removal device of another embodiment of the present invention,
