More particularly, the connecting bars for connecting and fixing the screen bars of the main screen at regular intervals are concave and curved toward the both ends gradually in a circular arc shape. So that the screen bar is connected and fixed to the connecting bar in a shape of front and back hung in front of the neck to narrow the width of the front part of the neck to be spaced apart from each other by a predetermined distance so that the contaminants of water flowing in the water channel At the same time, the rake for filtering the contaminants between the screen bars can filter out the obstacles caught in front of the neck portion, thereby preventing the necking phenomenon between the screen bars, Flows smoothly without any resistance by the connection bar A rotary barrel for preventing the maintenance of the rotary damper and the maintenance cost of the rotary damper so that the damper can smoothly and easily hang the damper by contact with the neck in a state in which the rake is in close contact with the narrow neck portion of the fixed screen bar. Quot;

Generally, the damper is installed in a repair channel such as a drainage pumping station, a water supply depot, a related water supply channel, a sewage disposal plant, and a dam, which is lower than the water surface, and the floating screen is screened with the main screen, (Such as straws, branches, binders, vinyls or aquatic plants).

FIG. 1 is a perspective view showing a conventional rotary damper, and FIG. 2 is a side view showing a conventional rotary damper.

1 and 2, a conventional rotary damper 10 includes a frame 12, a guide rail 14, a main screen 16, a potential screen 18, a rake 20, An apron 22, an endless chain 24, and a drive unit 26. [

Here, the frame 12 is installed on a water wall surface of a drainage pumping station, a water supply water intake pipe, a related water supply pipe, a sewage treatment plant, a dam, or the like, which is lower than the water surface, and the guide rail 14 is located inside the frame 12 Respectively.

The main screen 16 is installed between the guide rails 14, and is installed at a predetermined interval in the horizontal direction in order to filter off the contaminants that are separated along with the water flow.

The disposable screen 18 is installed at a lower front end of the main screen 16 in order to filter contaminants passing between the main screen 16 and the bottom surface of the disposable screen 18, And moves the contaminants led to the main screen 16 upwardly.

The apron 22 is disposed on the upper surface of the main screen 16 for collecting contaminants by guiding the raked droplets 20 rearwardly and located on the water surface of the upper part of the vibration damper, Are installed on the both side guide rails 14 so that the rake 20 is continuously rotated and circulated in one direction.

At this time, the endless chain 24 is rotated by the driving device 26, and the conveyor 28 collects the clogged material that has fallen behind the apron 22.

The vibration damper 10 according to the related art having the above-described structure operates the drive unit 26 to rotate the endless chain 24 guided by the guide rails 14, 24 are guided along the space between the main screens 16 to filter out the clogging between the main screens 16.

Thereafter, the rake 20 which has filtered the impurities is guided rearward along the apron 22 and is moved downward along the guide rail 14 at the rear of the apron 22 to drop the impurities, And is collected by a conveyor 28.

The driving device 26 for operating the conventional vibration damper 10 constructed as described above includes a drive motor 26 having a rotational force for smoothly rotating the endless chain 24 and the rake 20 to filter out contaminants And a sprocket 26b connected to the rotation shaft of the drive motor 26a and engaged with the endless chain 24. [

At this time, the rake 20 is transported upward by the endless chain 24 through the electric potential screen 18 and the main screen 16.

As described above, the conventional rotary damper has a configuration in which the main screen 16, in which a plurality of screen bars are fixed to the screen connecting bar 30 at a constant interval, The rake 20 lifts up and collects the obstacles caught on the main screen 16 and collects them.

However, in the case of the rotary damper as described above, the front width T and the rear width t between the screen bars of the main screen 16 are formed so as to maintain the same constant interval, As the rake 20 moves up and down to filter the contaminants, the contaminants trapped in the inside of the screen bars can not be removed while passing through the screen bars. And the flow of water is reduced as well as the flow of water is lowered due to the necking phenomenon, and when the necking phenomenon occurs, the worker moves down to the main screen of the damper and causes necking phenomenon It is necessary to remove the contaminants from the dust collectors and thus the maintenance and repair costs of the dust collectors are excessively generated.
