As shown in FIG. 3a, a sprocket 75 is attached to one end of the rod-shaped body 71 of the rotating brush 7. Since this sprocket 75 and the sprocket 519 fixed to the drive shaft 51 are connected by a chain, when the drive shaft 51 rotates, the rotating brush 7 also rotates.

On the other hand, as shown in FIG. 6, the scraper 6 is arranged at a position where the tip of the rotating brush 7 comes into contact with the rotating brush 7 when the rotating brush 7 rotates.

Note that 57 shown in FIG. 6 is a guide member that guides the movement of the filter plate group A.

Next, the operation of this dust removal device will be explained.

This dust removal device is installed, for example, in seawater or river water intake channels or various drainage ditches.

As shown in FIG. 3, the drive shaft 51 is rotationally driven by driving the electric motor 513.
Filter plate group A rotates toward the direction of arrow D in FIG. As a result, the debris in the water flow captured by the protruding piece 19 (see Fig. 4) of the filter plate 1 is conveyed toward the upper part of the debris removal device, passes over the sprocket 555 and the sprocket 515, and reaches the filter plate. Group A turns around and falls in a position facing downward and is captured.

At this time, a part of the garbage etc. transported by the filter plate group A does not fall but remains stuck to the filter plate group A and moves together with the filter plate group A.

After passing through the sprocket 515, the filter plate group A with dust and the like stuck thereon is guided by the guide member 57 and moves downward as shown in FIG. The rotary brush 7, which rotates in conjunction with the drive shaft 51, slides into contact with the downwardly directed filter plate group A at the H portion in the opposite direction, thereby removing dust and the like stuck to the filter plate group A. scraped off. Then, the filter plate group A can be regenerated to its original state free of dust and the like.

On the other hand, some of the dust scraped off by the rotating brush 7 falls, but some remains attached to the vicinity of the tip of the vane plate 73. When the rotating brush 7 further rotates, the tip of the blade plate 73 comes into contact with the scraper 6, as shown in FIG. Since the tip of the vane plate 73 in contact with the scraper 6 is constituted by an elastic plate 733 having elasticity, it deforms and passes through the scraper 6. At this time, the deformed elastic plate 733 bounces back to its original shape, so that the dust stuck to the elastic plate 733 is also blown away, and the rotating brush 7 is also regenerated to its original state free of dust. It is possible.

[Effect of idea]

As explained in detail above, according to the dust removal device according to the present invention, even if the dust etc. caught by the filter plate group sticks to the filter plate group, the stuck dust etc. can be easily removed. Therefore, the filter plate group is not clogged, and the efficiency of collecting dust and the like is improved, which is an excellent effect.
