照）。[Prior Art] Conventionally, this type of dust removal device has been designed to rotate vertically in an oblong shape between a bulkhead protruding from both side walls of a waterway and an intermediate support erected at the center of the downstream side of the bulkhead. An endless wire mesh screen cylinder is installed, the upper part is hung on the driving chain wheel, and the lower part is guided by a roughly U-shaped guide rail, so that the screen cylinder can be connected from the open upstream side of the screen cylinder. Flowing water is taken in, flows out toward the left and right side walls through the left and right meshes of the screen body, and is further guided downstream along the channel side walls, during which time it adheres to the inner surface of the screen body. There is a known structure in which the collected garbage is thrown into a dust collecting chute above the water surface and carried out to the outside of the screen cylinder (see, for example, Japanese Utility Model Publication No. 56-21855).

At this time, the long hair is pressed against the base fabric by the pressure of the running water, so fine dust is reliably captured and only water passes through. The screen cylinder that has captured fine dust is washed with washing water at the top, and
In particular, the long hairs hang downward to enhance the cleaning effect of fine dust, and after cleaning, the moisture is removed by compressed air. On the other hand, the water used to wash the long wool filter cloth falls onto the trough along with the dust and is forcibly discharged by the suction means.
The pressure in the upper space inside the screen barrel decreases slightly, facilitating the separation and removal of fine dust adhering to the long-hair filter cloth. In addition, the tips of the long hairs that hang down in the upper part of the screen body are soaked in washing water and washed.

15) is rotated by the motor (13) in the direction shown by the arrow (A) in Figure 1, raw water flows from the water channel (1) into the screen body (15) through its upstream opening,
Fine dust in the raw water is captured by the long-hair filter cloth (20), and the water flows outward through the long-hair filter cloth (20). At this time, the long bristles (21) are pressed against the base fabric of the filter cloth (20) by the pressure of the running water, so fine dust is reliably captured.
Only water passes through smoothly. The screen cylinder (15) that has captured the fine dust is then washed at the upper part by washing water from the washing water spray pipe (27) and the screen cylinder (15) is washed by the washing water from the washing water distribution pipe (27), and
At this time, the long hair (21
) hangs downward and efficiently washes away adhering dust. The cleaned screen cylinder (15) is blown with compressed air from the compressed air injection pipe (29).
Fine dust remaining on the long bristles (21) is blown away and separated and removed together with the washing water. In this way, the screen cylinder (15) from which the attached dust has been removed is rotated forward into the raw water. On the other hand, the wastewater from which the long wool filter cloth (20) was washed is
It falls onto the trough (30) together with the dust and is forcibly discharged by suction means such as a drainage pump.

The difference from the first embodiment is that the front and rear sprockets (1
0) and (11) are provided, two on the left and right respectively, and the long bristles (21) are immersed in the water in the garbage and washing wastewater receiving trough (30), and the trough (30) is moved horizontally by the swinging means (32). The main feature is that the long hair cleaning effect is improved by shaking the hair. That is, the trough (30) has its front and rear ends connected to the frame (4).
The connecting rod (34) connected to the trolley (33) is placed on a trolley (33) mounted on the upper part so as to be movable in the left and right direction.
Connect it to the crank pin (36) of the crank (35).
5) is connected to the chain mechanism (38) by the motor with reducer (37).
), etc., to swing the trough (30) back and forth in the left-right direction. In this way, by swinging the trough (30) in the horizontal direction, the long hair (21
) is washed using the same principle as the hair (21) is shaken and washed, and washing is performed in addition to spraying washing water and jetting air, so fine dust (including sludge, algae, etc.) adhering to the long hair (21) is more reliably removed. Separation and removal can be carried out. Note that the screen cylinder (15) and the like are completely the same as in the first embodiment, so detailed explanation will be omitted.
