The present invention is installed so that the water truck with a scraper can be moved forward and backward on the rail installed at the bottom of the sedimentation basin in the water treatment and sewage treatment plant. In the water-repellent rope traction sludge removal apparatus for removing sludge while moving, a circular arc-shaped scraper support plate, in which a scraper is coupled to a lower end, is installed in a predetermined portion of the subcar, allowing the scraper to move up and down without disturbing the water flow. And an arcuate scraper support plate is installed at the rear end of the water cart, so that it can be removed with sludge settled at the rear part of the sedimentation basin.

The sludge removal apparatus of the sedimentation basin which is conventionally used for this purpose is of various methods and structures, but the following two are representative of them. One is to use the bridge girder on the rail installed in the longitudinal direction on the structure of the sedimentation basin, and to install the sludge removal scraper device to the bottom of the bucket guard to reach the bottom of the sedimentation basin. It is driven by power and lowered to the sedimentation basin when moving forward, and on the contrary, when it is reversed, the bridge guard is reciprocated as a separate driving device to lift the sludge away from the sedimentation basin to remove the so-called sludge removal. It is a device, and the other is installed so that two rows of castless endless link chains can be rotated on the rail laid at the bottom of the sedimentation basin, and the sludge removal plates made of wood are fixed at regular intervals through the two rows of link chains. So-called link sieves that remove sludge by moving in close contact with the bottom of the settling basin Recognition sludge removal device.

However, the former bridge type sludge removal device is a reciprocating movement of the sedimentation basin structure at the top of the sedimentation basin structure from the top to the bottom of the sedimentation basin. There is a closed end where a high speed sedimentation device, such as a sloping plate sedimentation device, is installed to increase efficiency, and the latter link chain sludge removal device allows heavy cast link chains to run on rails installed directly on the sediment floor. As the weight of the facility was large, the power required was high, and the sludge removal plate was made of wood, which was limited in the width of the device.

Therefore, the applicant of the present invention installs an underwater truck having a sludge removal plate on the rail installed at the bottom of the sedimentation basin to reciprocate back and forth for the purpose of eliminating the defects of the conventional sludge removing device as described above. It is possible to drive by a low-off traction device installed outside the sedimentation basin, so that not only a high-speed sedimentation device such as a gradient plate sedimentation unit can be installed inside the sedimentation basin, but also one or several submersible bogies can be driven alone or by one driving unit. Simultaneous driving operation can be performed, and the operation of lifting and lowering of the sludge removing plate is performed by mechanical means by the guide device, not by power. Elected a submerged rope pull-out sludge removal device designed for planning The devices are disclosed in Utility Model Application Publication Nos. 84-1949 and 84-2666, and registered as Utility Model Registrations 38778 and 38777, respectively.

Compared with the conventional sludge removal apparatus, the above-mentioned pre-registration devices can be operated with less power, and their installation area can be reduced, so that they can be operated with economical facilities. Since it was not equipped, it was also possible to install a high-speed sedimentation device to increase sedimentation efficiency, such as a lodge plate sedimentation device, in water in the sedimentation basin.

In addition, in the water-repellent rope traction sludge removal apparatus as described above, the applicant of the present invention installs two sets of rails in the sedimentation basin in a double row, and mounts the water carts on the rails for drying, respectively. The front and rear traction ropes are interconnected to each other so that the two trucks can be reciprocated forward and backward alternately, and the front traction ropes are each wound by independent lifting and tensioning devices. It was previously filed with a submerged rope traction sludge removal device configured to be driven simultaneously by a single drive motor by winding on a drum. This apparatus is disclosed in Utility Model Publication No. 85-1000 and registered in Utility Model Registration No. 29029.

This device is designed to install two sub-tanks in the sedimentation basin in a double row, and to remove sludge by moving both sub-tanks to the front and back alternately by a single driving unit. There is no facility cost and power consumption can be reduced, and both underwater carts to remove the sludge continuously can improve the removal speed and efficiency of the sludge.

However, the above-mentioned prior application submerged rope traction sludge removal device is a flat plate-type scraper support plate, so the sludge is raised and raised during the scraper lifting operation due to the disturbance of water flow due to the high water flow and external frictional resistance during scraper lifting. There was a disadvantage in reducing the effect, and also because the scraper support plate is installed in the front portion or the middle portion of the water cart, the scraper did not finish until the rear portion of the sedimentation basin, the sludge settled in the rear portion of the sedimentation basin had a disadvantage.

The present invention has been devised to solve the defects of the prior application device as described above, the main purpose is to prevent the sludge re-injury to reduce the phenomenon of sludge re-emergence so that the scraper does not disturb the water flow during lifting operation. It is to provide a mold sludge removal device.

Referring to the effect of the present invention as described above is as follows.

1 and 2 show a state in which the sludge is removed while the subsea vehicle moves forward. In this case, the center of gravity of the cylindrical scraper support plate 30 provided at the rear end of the subsea vehicle 20 is based on the shaft 32. The scraper 40 fixed to the lower end of the cylindrical scraper support plate 30 is in contact with the bottom surface 1 'of the sedimentation basin 1, which is ubiquitous on the right side of the vertical line, and the rotation moment is hung on the shaft 32 in the clockwise direction. Under the driving force of the motor 11, the submersible truck 20 moves forward in the direction of the arrow shown on the rail 2 to scrape sludge deposited on the bottom surface 1 'of the sedimentation basin 1 and move it forward. do.

At this time, the guide roller 33 installed at the lower end of the cylindrical scraper support plate 30 moves in contact with the bottom surface 1 'of the sedimentation basin 1, thereby smoothly applying no excessive load to the scraper 40. Will move.

In this way, when the submersible bogie 20 moves to the front end of the sedimentation basin 1 as shown in FIG. 3, the sludge transported by the scraper 40 is collected by falling into the hopper 3 of the sedimentation basin 1, and an arc-shaped scraper Since the guide roller 33 installed at the lower end of the support plate 30 moves on the inclined surface 59a of the guide protrusion 59 formed to protrude toward the hopper 3 on the bottom surface 1 'of the sedimentation basin 1, The arc scraper support plate 30 rotates counterclockwise, and the scraper 40 fixed to the lower end of the arc scraper support tube 30 is separated from the bottom surface 1 ′ of the sedimentation basin 1.

And when the arc-shaped scraper support plate 30 is rotated as shown in FIG. 3, the center of gravity is ubiquitous to the left side of the vertical line with respect to the axis 32, and the switch operation portion 5 at the front end of the subsea vehicle 20.
